Overview

We are the world’s largest supplier by production capacity of utility‑grade wood pellets to major power generators. Since our entry into this business in 2010, we have executed multiple long‑term, take‑or‑pay off‑take contracts with utilities and large scale power generators and have built and acquired the production and terminaling capacity necessary to serve them. Our existing production constitutes approximately 14% of current global utility‑grade wood pellet production capacity and the product we deliver to our customers typically comprises a material portion of their fuel supply. We own and operate six industrial‑scale production plants in the Southeastern United States that have a fully contracted combined wood pellet production capacity of 2.9 million metric tons per year (“MTPY”). We constructed four of our production plants using our templated design and standardized equipment. A fifth plant, our largest in terms of production capacity, has been in operation since 2008. We also own dry‑bulk, deep‑water marine terminal assets at the Port of Chesapeake, Virginia (the “Chesapeake terminal”) and the Port of Wilmington, North Carolina (the “Wilmington terminal”), which reduce our storage and shiploading costs and enable us to reliably supply our customers. All of our facilities are located in geographic regions with low input costs and favorable transportation logistics. Owning these cost‑advantaged assets in a rapidly expanding industry provides us with a platform to generate stable and growing cash flows that we anticipate will enable us to increase our per‑unit cash distributions over time, which is our primary business objective.

We were formed on November 12, 2013 as a wholly owned subsidiary of our sponsor. On April 9, 2015, our sponsor contributed certain of our Predecessor’s assets and liabilities to us. On May 4, 2015, we completed an initial public offering (the “IPO”) of common units representing limited partner interests in the Partnership (“common units”). Our assets and operations are organized into a single reportable segment and are all located and conducted in the United States. Please read Part II, Item 8. “Financial Statements and Supplementary Data—Note 1, Description of Business and Basis of Presentation” for further discussion regarding our formation and organization.

We procure wood fiber and process it into utility‑grade wood pellets at our production plants. We load the finished wood pellets into railcars, trucks and barges that are transported to our owned or leased deep‑water marine terminal assets, where they are received, stored and ultimately loaded onto oceangoing vessels for transport to our principally European customers.

Our customers use our wood pellets as a substitute fuel for coal in dedicated biomass or co‑fired coal power plants. Wood pellets serve as a suitable “drop‑in” alternative to coal because of their comparable heat content, density and form. Due to the uninterruptible nature of our customers’ fuel consumption, our customers require a reliable supply of wood pellets that meet stringent product specifications. We have built our operations and assets to deliver and certify the highest levels of product quality, and our proven track record enables us to charge premium prices for this certainty. In addition to our customers’ focus on the reliability of supply, they are concerned about the combustion efficiency of

the wood pellets and their safe handling. Because combustion efficiency is a function of energy density, particle size distribution, ash/inert content and moisture, our customers require that we supply wood pellets meeting minimum criteria for a variety of specifications and, in some cases, provide incentives for exceeding our contract specifications.

Industry Overview

Our product, utility‑grade wood pellets, is used as a substitute for coal in both dedicated and co‑fired power generation and combined heat and power plants. It enables major power generators to profitably generate electricity in a manner that reduces the overall cost of compliance with mandatory greenhouse gas (“GHG”) emissions limits and renewable energy targets while also allowing countries to diversify their sources of electricity supply.

Unlike intermittent sources of renewable generation like wind and solar power, wood pellet‑fired plants are capable of meeting baseload electricity demand and are dispatchable (that is, power output can be switched on or off or adjusted based on demand). As a result, utilities and major power generators in Europe and Asia have made and continue to make long‑term, profitable investments in power‑plant conversions and new builds of generating assets that either co‑fire wood pellets with coal or are fully dedicated wood pellet‑fired plants. Such developments help generators in European and Asian markets maintain and increase baseload generating capacity, comply with binding climate change regulations and other emissions reduction targets and increase renewable energy usage at a lower cost to consumers and taxpayers than other forms of renewable energy generation.

The capital costs required to convert a coal plant to co‑fire biomass, or to burn biomass exclusively, are a fraction of the capital costs associated with implementing offshore wind and most other renewable technologies. Furthermore, the relatively quick process of converting coal‑fired plants to biomass‑fired generation is an attractive benefit for power generators whose generation assets are no longer viable as coal plants due to the expiration of operating permits or the introduction of taxes or other restrictions on fossil fuel usage or emissions of GHGs and other pollutants.

There also continues to be significant growth in the European and Asian demand for wood pellets as the preferred fuel source and lower‑cost alternative to delivered fossil fuels for district heating loops, for heating homes and commercial buildings and for the production of process heat at industrial sites. Increasingly, wood pellets are also being sought as a raw material input for bio‑based substitutes for traditional fossil fuel‑based fuels and chemicals. As these markets further develop, there will continue to be opportunities for utility‑grade wood pellet producers to serve this growing demand.

Recent Developments

Wilmington Drop‑Down

On October 2, 2017, pursuant to the terms of a contribution agreement by and between the Partnership and the First Hancock JV (the “Wilmington Contribution Agreement”), the First Hancock JV sold to the Partnership all of the issued and outstanding limited liability company interests in Enviva Port of Wilmington, LLC (“Wilmington”), which owns the Wilmington terminal. We refer to this transaction as the “Wilmington Drop-Down.”

The purchase price for Wilmington was $130.0 million, which included an initial payment of $54.6 million, net of an approximate purchase price adjustment of $1.4 million. The initial payment was funded with borrowings from revolving credit commitments and cash on hand. We accounted for the Wilmington Drop-Down as a combination of entities under common control at historical cost in a manner similar to a pooling of interests. Accordingly, the consolidated financial statements for the periods prior to the acquisition were retrospectively recast to reflect the acquisition as if it had occurred on May 15, 2013, the date Wilmington was originally organized.

The Wilmington terminal, which is capable of receiving product by rail and truck, has the capacity to store up to 90,000 metric tons (“MT”) of wood pellets, and load up to Panamax-sized vessels. It utilizes state-of-the-art handling equipment and storage infrastructure designed to maintain product quality and safety with throughput capacity of up to 3.0 million MTPY of wood pellets.

Wilmington will handle up to approximately 600,000 MTPY of throughput from our wood pellet production plant located in Sampson, North Carolina (the “Sampson plant”) and is party to a long-term terminal services agreement with Enviva Pellets Greenwood, LLC, a wholly owned subsidiary of the Second Hancock JV (“Greenwood”). Wilmington will handle throughput volumes sourced from Greenwood’s wood pellet production plant located in Greenwood, South Carolina (the “Greenwood plant”). The terminal services agreement with Greenwood provides for deficiency payments to Wilmington if minimum throughput requirements are not met.

In addition, the Wilmington Contribution Agreement contemplates that Wilmington will enter into a long-term terminal services agreement (the “Wilmington Hamlet TSA”) with the First Hancock JV and Enviva Pellets Hamlet, LLC (“Hamlet”) to receive, store and load wood pellets from the First Hancock JV’s proposed production plant in Hamlet, North Carolina (the “Hamlet plant”) when the First Hancock JV completes construction of the Hamlet plant. The Wilmington Hamlet TSA also provides for deficiency payments to Wilmington if minimum throughput requirements are not met. Pursuant to the Wilmington Contribution Agreement, following notice of the anticipated first delivery of wood pellets to the Wilmington terminal from the Hamlet plant, Wilmington, Hamlet, and the First Hancock JV would enter into the Wilmington Hamlet TSA and the Partnership would make a final payment of $74.0 million in cash or common units to the First Hancock JV, subject to certain conditions, as deferred consideration for the Wilmington Drop-Down.

Wilmington also entered into a throughput option agreement with the sponsor granting the sponsor, subject to certain conditions, the option to obtain terminal services at the Wilmington terminal at marginal cost throughput rates for wood pellets produced by one of the sponsor’s potential wood pellet production plants. 

Senior Notes Due 2021

On November 1, 2016, we issued $300.0 million in aggregate principal amount of 8.5% senior unsecured notes due November 1, 2021 (the “Senior Notes”) to eligible purchasers in a private placement transaction. In August 2017, holders of 100% of the Senior Notes tendered such notes in exchange for newly issued registered notes with terms substantially identical to the Senior Notes (except that the registered notes are not subject to restrictions on transfer).

On October 10, 2017, we completed the issuance to an institutional investor in a private placement transaction of an additional $55.0 million in aggregate principal amount of Senior Notes at a price of 106.25% of par plus accrued interest from May 1, 2017. The additional Senior Notes have the same terms as our outstanding Senior Notes.

The sale of the additional Senior Notes at a purchase price of $58.4 million resulted in gross proceeds of approximately $60.0 million, after including accrued interest of $2.1 million and deducting estimated expenses of approximately $0.5 million. The net proceeds were used to repay the borrowings on our revolving credit facility that were used to fund the Wilmington Drop-Down and for general partnership purposes.

In December 2017, the holder of the additional Senior Notes tendered such notes in exchange for newly issued registered notes with terms substantially identical to such additional Senior Notes (except that the registered notes are not subject to restrictions on transfer). The additional Senior Notes will be treated together with the outstanding Senior Notes as a single class for all purposes under the Indenture.

Sale of the Wiggins Plant

In December 2016, we initiated a plan to sell our 110,000 MTPY production plant located in Wiggins, Mississippi and related assets (the “Wiggins plant”). We sold the Wiggins plant to a third-party buyer for a purchase price of $0.4 million on December 27, 2017, and on December 28, 2017, Enviva Pellets Wiggins, LLC (“Wiggins”), the owner of the Wiggins plant, was dissolved. We recorded a loss on the sale of $0.8 million, net, upon deconsolidation.

At‑the‑Market Offering Program

On August 8, 2016, we filed a prospectus supplement to our shelf registration filed with the U.S. Securities Exchange Act Commission (“SEC”) on June 24, 2016, for the continuous offering of up to $100.0 million of common

units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of our offerings. In August 2016, we also entered into an equity distribution agreement (the “Equity Distribution Agreement”) with certain managers pursuant to which we may offer and sell common units from time to time through or to one or more of the managers, subject to the terms and conditions set forth in the Equity Distribution Agreement, of up to an aggregate sales amount of $100.0 million (the “ATM Program”).

During the years ended December 31, 2017 and 2016, we sold 71,368 and 358,593 common units, respectively, under the Equity Distribution Agreement for net proceeds of $1.9 million, net of an insignificant amount of commissions, during 2017, and net proceeds of $9.3 million, net of $0.1 million of commissions, during 2016. Accounting and other fees of approximately $0.2 million were offset against the proceeds during 2017. Deferred issuance costs of approximately $0.4 million, primarily consisting of legal, accounting and other fees, were offset against the proceeds during 2016. Net proceeds from sales under the ATM Program were used for general partnership purposes. As of February 16, 2018, $88.6 million of common units remained available for issuance under the ATM Program.

Assets and Operations

Our Production Plants

We own and operate six industrial‑scale wood pellet production plants located in the Mid‑Atlantic and the Gulf Coast regions of the United States, geographic areas in which wood fiber resources are plentiful and readily available. These facilities are designed to operate 24 hours per day, 365 days per year, although we schedule up to 15 days of maintenance for our plants during each calendar year. There are no regularly required major turnarounds or overhauls.

Mid‑Atlantic Region Plants

The following table describes our four wood pellet production plants in the Mid‑Atlantic region:

Ahoskie

We acquired the site of the Ahoskie plant in December 2010 and constructed a dedicated wood pellet production plant in Ahoskie, North Carolina (the “Ahoskie plant”) in less than one year, commencing operations in November 2011. Through an expansion completed in June 2012, we increased the plant’s production from 260,000 MTPY to 350,000 MTPY and have made further improvements to increase production to its current capacity of 400,000 MTPY.

Production from the Ahoskie plant is transported by truck to our Chesapeake terminal.

Northampton

Our wood pellet production plant in Northampton, North Carolina (the “Northampton plant”) was constructed based on the Ahoskie plant design, utilizing the same major equipment suppliers. The Northampton plant currently produces 550,000 MTPY of wood pellets.

Production from the Northampton plant is transported by truck to our Chesapeake terminal.

Sampson

The Sampson plant, which we acquired from the First Hancock JV in December 2016, commenced operations during the fourth quarter of 2016. The Sampson plant was built based on our templated design and we believe that it will produce 545,000 MTPY of wood pellets in 2018 and reach an annual production capacity of 600,000 MTPY by 2019.

Production from the Sampson plant is transported by truck to our Wilmington terminal.

Southampton

We acquired a wood pellet production plant in Southampton County, Virginia (the “Southampton plant”) from the First Hancock JV in December 2015 (the “Southampton Drop‑Down”). The Southampton plant is a build‑and‑copy replica of our Northampton plant and currently produces 550,000 MTPY of wood pellets.

Production from the Southampton plant is transported by truck to our Chesapeake terminal.

Gulf Coast Region Plants

The following table describes our two wood pellet production plants in the Gulf Coast region:

Cottondale

Our sponsor acquired Green Circle Bio Energy, Inc., which owns a wood pellet production plant in Cottondale, Florida (the “Cottondale Plant”), in January 2015, changed the name of this entity to Enviva Pellets Cottondale, LLC (“Cottondale”) and contributed Cottondale to us in April 2015. The Cottondale plant was commissioned in 2008 and has since undergone several expansions and process improvements. Expansion projects during 2016 and 2017 increased production from 720,000 MTPY to 730,000 MTPY.

Production from the Cottondale plant is transported approximately 50 miles by short‑line rail to a warehouse that can store up to 32,000 MT of wood pellet inventory at a third-party deep water marine terminal located in Port Panama City, Florida (the “Panama City terminal”).

Amory

We purchased a wood pellet production plant in Amory, Mississippi (the “Amory plant”) in August 2010. The Amory plant initially consisted of three pellet mills producing at a rate of 41,500 MTPY. Through basic operational improvements and installation of a fourth pellet mill, the Amory plant currently produces 120,000 MTPY.

Production from the Amory plant is transported by barge to a third‑party deep‑water marine terminal in Mobile, Alabama (the “Mobile terminal”).

Logistics and Storage Capabilities

To‑Port Logistics and Port Infrastructure

We site our production plants to minimize wood fiber procurement and logistics costs. Our production plants are strategically located in advantaged fiber baskets and near multiple truck, rail, river and ocean transportation access points. We also have inland waterway access and rail access at our Chesapeake terminal and Wilmington terminal and the Panama City terminal. Our multi‑year fixed‑cost contracts with third‑party logistics providers allow for long‑term visibility into our to‑port logistics cost structure.

The wood pellets produced at our plants must be stored, terminaled and shipped to our principally European customers. Limited deep‑water, bulk terminaling assets exist in the Southeastern United States, and very few of them have the appropriate handling and storage infrastructure necessary for receiving, storing and loading wood pellets. In response to such scarcity, we have vertically integrated our Mid‑Atlantic operations downstream to encompass finished product logistics and storage. As a largely fixed cost and capital intensive piece of the value chain, our port infrastructure allows us to ship incremental product from our regional plants at a small fraction of the cost of our competitors. Management of port terminal infrastructure is also a key element in reducing distribution‑related costs as it allows us to manage the arrival and loading of vessels. Additionally, we are able to improve our cost position by maintaining a dedicated berth where pellets from our Mid‑Atlantic region plants have priority and equipment with sufficient load-rate capabilities to turn around vessels within the allotted time windows.

In addition to terminaling wood pellets from our production plants, we will, on occasion, provide terminaling services for third‑ and related-party wood pellet producers as well as for owners of other dry-bulk commodities. 

Port Operation in the Mid‑Atlantic Region

We acquired the Chesapeake terminal in January 2011 and converted it into a major dry‑bulk terminal. The Chesapeake terminal receives, stores and loads wood pellets for export and serves as the shipment point for products produced at our Ahoskie, Northampton and Southampton plants. The Chesapeake terminal accommodates Handysize, Supramax and Panamax‑sized vessels, and has a 200‑car rail yard adjacent to a Norfolk Southern track, a loading/unloading system that accommodates deliveries by truck, rail and barge and a highly automated conveying system. In May 2011, we erected a 157‑foot tall, 175‑foot wide storage dome that receives, stores and loads up to 45,000 MT of wood pellets. In April 2013, we placed into operation a second storage dome at the site to add an additional 45,000 MT of storage.

The Chesapeake terminal’s storage and loading capacity is more than adequate to store and facilitate the loading of the wood pellets produced from our Northampton, Southampton and Ahoskie plants, and its location decreases our customers’ transportation time and costs. Efficiently positioned near our Ahoskie, Northampton, and Southampton plants, the Chesapeake terminal delivers up to a three‑ to four‑day European shipping advantage compared to other Southern or Gulf Coast ports. In addition, because we own the Chesapeake terminal, we enjoy preferential berth access and loading, which minimizes costs of shipping and logistics without the need for excess storage. Our ownership and operation of this terminal enable us to control shipment of the production of our Mid‑Atlantic region plants that it serves.

Wood pellets produced at our Sampson plant are terminaled at our Wilmington terminal. The Wilmington terminal accommodates Handysize, Supramax and Panamax‑sized vessels, and has a receiving system that accommodates deliveries by truck and rail, a highly automated conveying system and two wood pellet storage domes with capacities of 45,000 MT each. The Wilmington terminal’s storage and loading capacity is more than adequate to store and facilitate the loading of pellets produced from our Sampson plant and its location decreases transportation time and costs through the entire supply chain. We benefit from preferential berth access and loading at our Wilmington terminal, which minimizes costs of shipping and logistics without the need for excess storage.

Port Operation in the Gulf Coast Region

Wood pellets from our Cottondale plant are transported via short‑line rail to the Panama City terminal, where we store up to 32,000 MT of wood pellet inventory in a warehouse at Port Panama City. Production from the Cottondale plant is received, stored and loaded under a long‑term warehouse service agreement with the Panama City Port Authority and a stevedoring contract, each of which runs through September 2023 and may be extended by us for an additional five-year period.

Wood pellets produced at our Amory plant are transported by barge to the Mobile terminal, where, pursuant to a throughput agreement with Cooper Marine & Timberlands (“Cooper”), we export from Cooper’s ChipCo terminal. This privately owned and maintained deep‑water, multi‑berth terminal operates 24 hours per day, seven days per week and is the fleeting and loading point for production from our Amory plant. The Amory plant is sited along a major inland waterway that makes transportation to the Mobile terminal easy and efficient, thereby reducing emissions and costs. Our ability to store our wood pellets in barges provides a capital‑light, flexible solution that accommodates the storage needs of the Amory plant.

Please read Part II, Item 8. “Financial Statements and Supplementary Data—Significant Accounting Policies—Segment and Geographic Information” for more information regarding our plants, terminals and other long‑lived assets.

Our Relationship with Our Sponsor

Our sponsor, Enviva Holdings, LP, is a majority owned subsidiary of the Riverstone Funds.

Our sponsor owns approximately 9% of our common units, all of our subordinated units and our General Partner. Our General Partner owns our incentive distribution rights, which entitles our General Partner to increasing percentages of our cash distributions above certain targets. As a result, our sponsor is incentivized to facilitate our access to accretive acquisitions and organic growth opportunities, including those pursuant to the right of first offer it granted to us in connection with our IPO.

In November 2014, Enviva Development Holdings, LLC (“Development Holdings”) entered into the First Hancock JV with Hancock Natural Resource Group, Inc. and certain other affiliates of John Hancock Life Insurance Company (U.S.A.) to acquire, develop and construct wood pellet production plants and deep-water marine terminals such as the Southampton, Sampson and Hamlet plants and the Wilmington terminal. In December 2017, Development Holdings entered into the Second Hancock JV with Hancock Natural Resource Group, Inc. and certain other affiliates of John Hancock Life Insurance Company (U.S.A.) to acquire, develop and construct wood pellet production plants and deep-water marine terminals in the Southeastern United States. Development Holdings is the managing member and Enviva Management is the operator of the Hancock JVs; together, they are responsible for managing the activities of the First Hancock JV and the Second Hancock JV (together, the “Hancock JVs”), including the development and construction of the development projects of the Hancock JVs.

Our Sponsor’s Assets and Development Projects

Hamlet Plant

The First Hancock JV has secured permits and commenced construction of the Hamlet plant, which is strategically sited in an attractive wood fiber basket and will be constructed using our “build‑and‑copy” approach, using substantially the same design and equipment as the Sampson plant. Production from the Hamlet plant, once completed, will be terminaled at the Wilmington terminal.

Greenwood Plant

As its first investment, the Second Hancock JV, through a wholly owned subsidiary, entered into an agreement to purchase the Greenwood plant. Upon closing, the Second Hancock JV intends to make investments in the Greenwood plant to improve its operational efficiency and increase its production capacity to 600,000 MTPY. The production of the

Greenwood plant initially will be sold to the Partnership under a take-or-pay off-take contract and will continue to be exported from the Partnership’s Wilmington terminal.

Other Sponsor Development Projects

In addition to the projects discussed above, the Second Hancock JV is pursuing the development of additional deep‑water marine terminals and production plants. The Second Hancock JV has executed an agreement with the Jackson County Port Authority granting the Second Hancock JV an option to build and operate a marine export terminal at the Port of Pascagoula, Mississippi, which would service new, regionally proximate production plants, including a potential production plant in Lucedale, Mississippi.

In connection with the closing of the IPO in 2015, we entered into a purchase rights agreement (the “Purchase Rights Agreement”) with our sponsor, pursuant to which our sponsor granted us a five‑year right of first offer to acquire any wood pellet production plants and associated deep‑water marine terminals that it or the Hancock JVs may develop or acquire and elect to sell. We expect to continue to pursue the acquisition of such assets from our sponsor and the Hancock JVs to the extent that they are supported by long‑term off‑take contracts with creditworthy counterparties and have long useful lives, stable cost positions and advantaged locations.

Although we expect to continue to have the opportunity to acquire assets, including those described above, from our sponsor and the Hancock JVs, there can be no assurance that our sponsor or the Hancock JVs will complete their development projects or that our sponsor will decide to sell, or compel the Hancock JVs to sell, assets or completed development projects to us. The right of first offer under the Purchase Rights Agreement expires in May 2020.

Customers

For the year ended December 31, 2017, we generated substantially all of our revenues from sales under long‑term take‑or‑pay off‑take contracts with customers outside of the United States. We seek to fully contract our production capacity through long‑term off‑take contracts and supplement such agreements with smaller contracts of intermediate or short duration to take advantage of opportunities in the market.

Depending on the specific off‑take contract, shipping terms are either Cost, Insurance and Freight (“CIF”), Cost and Freight (“CFR”) or Free on Board (“FOB”). Under a CIF contract, we procure and pay for shipping costs, which include insurance and all other charges, up to the port of destination for the customer. Under a CFR contract, we procure and pay for shipping costs, which include insurance (excluding marine cargo insurance) and all other charges, up to the port of destination for the customer. Shipping costs under CIF and CFR contracts are included in the price to the customer and, as such, are included in revenue and cost of goods sold. Under FOB contracts, the customer is directly responsible for shipping costs. We seek to enter into fixed-price shipping contracts with reputable shippers matching the terms and volumes of our contracts for which we are responsible for arranging shipping.

We have long-term, take‑or‑pay off‑take contracts with utilities and large European power generators such as Drax Power Limited (“Drax”), Ørsted Bioenergy & Thermal Power A/S (“Ørsted,” formerly known as “DONG Energy Thermal Power A/S”), Lynemouth Power Limited (“Lynemouth Power”), Engie Energy Management SCRL (“ENGIE”), MGT Teesside Limited (“MGT”) (through two contracts with the First Hancock JV) and RWE Supply and Trading GmbH (“RWE”).  

Drax Contracts.  We began selling utility‑grade wood pellets pursuant to a take-or-pay off-take contract with Drax (the “First Drax Contract”) on April 1, 2013. We supplied 468,750 MT for the first delivery year and will supply 1.0 million MTPY of wood pellets through 2022. In connection with the Southampton Drop‑Down, the First Hancock JV assigned to us a ten‑year contract with Drax (the “Second Drax Contract”). The Second Drax Contract commenced on December 1, 2015, and we supplied 385,000 MT for the first delivery year, supplied 500,000 MT for the second delivery year and will supply 500,000 MTPY for years three through ten.

Ørsted Contract.  In connection with the Sampson Drop‑Down, the First Hancock JV assigned to us a ten‑year take‑or‑pay off‑take contract with Ørsted. This contract commenced September 1, 2016 and provides for sales of

360,000 MTPY for the first delivery year and 420,000 MTPY for years two through ten. In the fourth quarter of 2017, the Partnership entered into an amendment to the contract with Ørsted for the supply of an incremental 200,000 MT from late 2018 through mid-2021. Ørsted’s obligations under the contract are guaranteed by its parent, Ørsted A/S.

Lynemouth Power Contract.  We entered into a take‑or‑pay off‑take contract to supply wood pellets to Lynemouth Power. Lynemouth Power is converting its coal‑fired power station in the United Kingdom to a biomass fired power station. Deliveries under this contract commenced in late 2017, are expected to ramp to full supply of 800,000 MTPY of wood pellets in 2018, and will continue through the first quarter of 2027. The volumes under the Lynemouth Power Contract are denominated in U.S. Dollars, except for 160,000 MTPY that are denominated in British Pound Sterling (“GBP”).

ENGIE Contracts.  We began selling 480,000 MTPY of utility‑grade wood pellets to Electrabel, a subsidiary of ENGIE, under a contract that commenced in June 2011 and continued through 2017. In May 2017 we entered into a new agreement to supply a total of 450,000 MT of wood pellets to ENGIE from mid-2017 through and including 2019. We recently entered into two additional agreements with ENGIE to sell 90,000 MT in 2018 and an aggregate 585,000 MT from 2019-2023.

EVA‑MGT Contracts.  We have contracted with the First Hancock JV to supply 375,000 MTPY of wood pellets (the “EVA-MGT Contract”) to MGT Teesside Limited’s Tees Renewable Energy Plant (the “Tees REP”). The EVA‑MGT Contract commences in 2019, ramps to full supply in 2021, and continues through 2034. The EVA-MGT Contract is denominated in U.S. Dollars for commissioning volumes in 2019 and in GBP thereafter.

In connection with the Sampson Drop‑Down, we entered into a second contract with the First Hancock JV to supply an additional 95,000 MTPY of the contracted volume to the Tees REP. For more information on the EVA‑MGT Contracts, please read Part III, Item 13. “Certain Relationships and Related Transactions, and Director Independence—Agreements with Affiliates—EVA‑MGT Contracts.”

RWE Contracts.  We have contracted with RWE pursuant to two confirmations under master agreements to sell 720,000 MT of wood pellets to RWE from our terminal locations and to purchase 720,000 MT of wood pellets from RWE in British Columbia during the period from January 2020 through December 2021.

We also have entered into several other contracts that have smaller off-take quantities than the contracts described above. We diversified our customer base during 2017; however, our three largest customers accounted for 93% of the Partnership’s product sales in 2017.

We refer to the structure of our contracts as “take‑or‑pay” because they include a firm obligation of the customer to take a fixed quantity of product at a stated price and provisions that compensate us in the case of our customer’s failure to accept all or a part of the contracted volumes or for termination by our customer. Our long-term contracts typically provide for annual inflation‑based adjustments or price escalators. Certain of our long-term contracts also contain provisions that allow us to increase or decrease the volume of product that we deliver by a percentage of the base volume of the contract, as well as cost pass‑through provisions related to stumpage, fuel or transportation costs and price adjustments for actual product specifications. In addition, certain of our long-term contracts and related arrangements provide for certain cost recovery and sharing arrangements in connection with certain changes in law or sustainability requirements as well as payments to us in the case of their termination as a result of such changes.

In addition to our long-term contracts, we also sell prompt deliveries of product to new and existing customers. On occasion, we will intermediate dislocations in the market by entering into back-to-back transactions with physical delivery. In some instances, a customer may request to cancel, defer, or accelerate a shipment. Contractually, we will seek to optimize our position by selling or purchasing the subject shipment to or from another party, including in some cases a related party, either within our contracted off‑take portfolio or as an independent transaction on the spot market. In most instances, the original customer pays us a fee, including reimbursement of any incremental costs, which is included in “Other revenue.” We also provide terminaling services for third‑party wood pellet producers as well as for owners of other bulk commodities.

Contracted Backlog

As of February 15, 2018, we had approximately $5.8 billion of product sales backlog for firm contracted product sales to major power generators compared to approximately $5.7 billion as of February 1, 2017. Backlog represents the revenue to be recognized under existing contracts assuming deliveries occur as specified in the contract. Expected future product sales revenue denominated in foreign currencies, excluding revenue hedged with foreign currency forward contracts, are included in U.S. Dollars at February 15, 2018 forward rates. Please read Part II, Item 8. “Financial Statements and Supplementary Data—Derivative Instruments” for more information regarding our foreign currency forward contracts.

Our expected future product sales revenue under our contracted backlog as of February 15, 2018 is as follows (in millions):

Wood Fiber Procurement

Although stumpage constitutes a small portion of our total cost of delivered products, wood fiber procurement is a vital function of our business, and cost‑effective access to wood fiber is an important factor in our pricing stability. Our raw materials are byproducts of traditional timber harvesting, principally the tops and limbs of trees as well as other low‑value wood materials that are generated in a harvest. We procure wood fiber directly from timber owners, loggers and other suppliers. We also opportunistically acquire industrial residuals (sawdust and shavings) and forest residuals (woodchips and slash) when they provide a cost advantage. Due to the moisture content of unprocessed wood, it cannot be transported economically over long distances. Therefore, the specific regional wood fiber resource supply and demand balance dictates the underlying economics of wood fiber procurement. For this reason, we have elected to site our facilities in some of the most robust and advantaged fiber baskets in the world.

Our customers are subject to stringent requirements regarding the sustainability of the fuels they procure. In addition to our internal sustainability policies and initiatives, our wood fiber procurement is conducted in accordance with leading forest certification standards. Our fiber supply chains are routinely audited by independent third parties. We maintain multiple forest certifications including: Forest Stewardship Council (FSC®) Chain of Custody, FSC® Controlled Wood, Programme for the Endorsement of Forest Certification (PEFC™) Chain of Custody, Sustainable Forestry Initiative (SFI®) Fiber Sourcing and SFI® Chain of Custody. We have obtained independent third-party certification for our Ahoskie, Cottondale, Northampton, Sampson and Southampton plants to the applicable Sustainable Biomass Program (SBP) Standards in 2016 and 2017. We expect that our Amory plant will obtain third-party SBP certification in early 2018.

Our wood fiber demand is complementary to, rather than in competition with, demand for high‑grade wood for use by most other forest‑related industries, such as lumber and furniture making. For example, improvements in the U.S. housing construction industry increase the demand for construction‑quality lumber, which in turn increases the available supply of the low‑cost pulpwood and mill residues that are used in wood pellet production. By using commercial thinnings and byproducts as raw materials, wood pellet production also indirectly supports other forest‑related industries as well as the sustainable management of commercial forests.

The wood fiber used for wood pellet production comprises predominantly pulpwood, which derives its name from its traditional use by the pulp and paper industry and includes roundwood (typically thinnings from forest management operations and the tops and branches from sawlogs), and wood residues (primarily mill residues, a byproduct of sawmilling and veneer mill operations). Our procured wood fiber consists of:

Demand for the non‑merchantable trees, waste products or byproducts that we use is generally low because they have few competing uses. The tops, limbs and other low‑grade wood fiber we purchase would otherwise generally be left on the forest floor, impeding reforestation, or burned. Wood pellet production provides a profitable use for the residues from sawmill and furniture industries and for the trees that are thinned to make room for higher value lumber‑grade timber. U.S. demand for such low grade wood fiber historically emerged from the pulp and paper industry. However, due to the decline in demand from paper and pulp, many landowners lack commercial markets for this wood fiber. Wood pellet producers help fill the gap.

As a result of the fragmented nature of tract ownership, we procure raw materials from hundreds of landowners, loggers and timber industry participants, with no individual landowner representing a material fraction of any of our production plants’ needs. Our wood fiber is procured under a variety of arrangements, including (1) logging contracts for the thinnings, pulpwood and other unmerchandised chip‑and‑saw timber cut by a harvester, (2) in‑woods chipping contracts where we may also provide the actual harvesting assets and (3) contracts with timber dealers. Via our internal Track and Trace system, we maintain 100% traceability of the primary wood that is delivered to us directly from forests. Any supplier delivering wood to one of our plants must first share the details about the forest characteristics of the tract from which the wood is sourced with our forestry staff so we can verify that it meets our strict sustainability criteria. Our supplier contracts require a certification that the relevant tract information has been entered into our database before wood may be delivered directly from a particular tract. We summarize all such tract information periodically and publish tract‑level details on our website. During 2017, we sourced wood fiber from approximately 300 suppliers, including landowners growing both hardwoods and softwoods and other suppliers. The diversity of our supply base enables us to maintain stable costs, and our facilities’ advantaged siting ensures consistent and reliable deliveries at lower cost than others in our region or industry.

Competition

We compete with other utility‑grade wood pellet producers for long‑term, take‑or‑pay off‑take contracts with major power generation customers. Competition in our industry is based on the price, quality and consistency of the wood pellets produced, the reliability of wood pellet deliveries and the producer’s ability to verify and document, through customer and third‑party audits, that its wood pellets meet the regulatory sustainability obligations of a particular customer.

Most of the world’s current wood pellet production plants are owned by small, private companies, with few companies owning or operating multiple plants. Few companies have the scale, technical expertise or commercial infrastructure necessary to supply utility‑grade wood pellets under large, long‑term off‑take contracts with power generators.

We are the largest producer by production capacity, and consider other companies with comparable scale, technical expertise or commercial infrastructure to be our competitors, including AS Graanul Invest, Pinnacle Renewable Energy Inc., Drax Biomass Inc., Georgia Biomass, LLC, Fram Renewable Fuels, LLC, Highland Pellets LLC, Pacific BioEnergy Corporation, and The Westervelt Company.

Employees

We are party to a management services agreement with Enviva Management, pursuant to which Enviva Management provides us with the employees, management and services necessary for the operation of our business. As of December 31, 2017, Enviva Management had 652 employees. Please read Part II, Item 13. “Financial Statements and

Supplementary Data—Related-Party Transactions” for more information regarding our management services agreement with Enviva Management.

Environmental Matters

Our operations are subject to stringent and comprehensive federal, state and local laws and regulations governing matters including environmental protection, occupational health and safety and the release or discharge of materials into the environment, including air emissions and wastewater discharges. These laws and regulations may (i) require acquisition, compliance with and maintenance of certain permits or other approvals to conduct regulated activities, (ii) impose technology requirements or standards on our operations, (iii) restrict the amounts and types of substances that may be discharged or emitted into the environment, (iv) limit or prohibit construction or timbering activities in sensitive areas such as wetlands or areas inhabited by endangered or threatened species, (v) govern worker health and safety aspects of operations, (vi) require measures to investigate, mitigate or remediate releases of hazardous or other substances from our operations and (vii) impose substantial liabilities, including possible fines and penalties for unpermitted emissions or discharges from our operations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of investigatory and remedial obligations and the issuance of orders enjoining some or all of our operations in affected areas.

Moreover, the global trend in environmental regulation is towards increasingly broad and stringent requirements for activities that may affect the environment. Any changes in environmental laws and regulations or re‑interpretation of enforcement policies that result in more stringent and costly requirements could have a material adverse effect on our operations and financial position. Although we monitor environmental requirements closely and budget for the expected costs, actual future expenditures may be different from the amounts we currently anticipate spending. Moreover, certain environmental laws impose strict joint and several liability for costs to clean up and restore sites where pollutants have been disposed or otherwise spilled or released. We cannot assure you that we will not incur significant costs and liabilities for remediation or damage to property, natural resources or persons as a result of spills or releases from our operations or those of a third party. Although we believe that our competitors will face similar environmental requirements, other market factors may prevent us from passing on any increased costs to our customers. Although we believe that we are in substantial compliance with existing environmental laws and regulations and that continued compliance with existing requirements will not materially adversely affect us, there is no assurance that the current levels of regulation will continue in the future.

The following summarizes some of the more significant existing environmental, health and safety laws and regulations applicable to our operations, the failure to comply with which could have a material adverse impact on our capital expenditures, results of operations and financial position.

Air Emissions

The Clean Air Act, as amended (the “CAA”), and state and local laws and regulations that implement and add to CAA requirements, regulate the emission of air pollutants from our facilities. The CAA imposes significant monitoring, recordkeeping and reporting requirements for these emissions. These laws and regulations require us to obtain pre‑approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and strictly comply with stringent air permits, and in certain cases utilize specific equipment or technologies to control and measure emissions. Obtaining these permits can be both costly and time intensive and has the potential to delay the opening of new plants or the significant expansion of existing plants.

The CAA requires that we obtain various construction and operating permits, including, in some cases, Title V air permits. In certain cases, the CAA requires us to incur capital expenditures to install air pollution control devices at our facilities. We are also required to control fugitive emissions from our operations and may face fines, penalties or injunctive orders in connection with fugitive emissions from our operations.  We have incurred, and expect to continue to incur, substantial administrative, operating and capital expenditures to maintain compliance with CAA requirements that have been promulgated or may be promulgated or revised in the future.

Climate Change and Greenhouse Gases

In response to findings that emissions of carbon dioxide, methane and GHGs present an endangerment to public health and the environment, the U.S. Environmental Protection Agency (the “EPA”) has adopted regulations under existing provisions of the CAA that require a reduction in emissions of GHGs from motor vehicles and certain stationary sources. At this time, the EPA requires biomass facilities with GHG emissions above 75,000 tons per year that are otherwise subject to CAA permitting to undergo CAA permitting for their GHG emissions. Any other legislation or regulations that require permitting or reporting of GHG emissions or limit such emissions from our equipment and operations or from biomass‑fired power plants operated by our customers could require us to incur costs to reduce such emissions or negatively impact demand for wood pellets. Furthermore, scientists have concluded that increasing concentrations of GHGs in the earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods and other climatic events. If any such effects were to occur, they could have an adverse effect on our operations.

Water Discharges

The Federal Water Pollution Control Act, as amended (the “Clean Water Act”), as well as state laws and regulations that implement, and may be more stringent than, the Clean Water Act, restrict the discharge of pollutants into waters of the United States. Any such discharge of pollutants must be performed in accordance with the terms of a permit issued by the EPA or the implementing state agency. In addition, the Clean Water Act and implementing state laws and regulations require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non‑compliance with discharge permits or other requirements of the Clean Water Act and analogous state laws and regulations. These permits generally have a term of five years. Although our facilities are presently in compliance with these requirements, changes to the terms and conditions of our permits in future renewals or new or modified regulations could require us to incur additional capital or operating expenditures, which may be material.

Pursuant to the Clean Water Act, the EPA has adopted the Discharge of Oil regulation, which requires any person in charge of an onshore facility to report any discharge of a harmful quantity of oil into U.S. navigable waters, adjoining shorelines or the contiguous zone. A harmful quantity is any quantity of discharged oil that violates state water quality standards, causes a film or sheen on the water’s surface or leaves sludge or emulsion beneath the surface. Spills from our production plants that are located along waterways or from our deep‑water marine terminal facilities may result in fines, penalties and obligations to respond to and remediate any such spills.

Spill Response and Release Reporting

Certain of our facilities are subject to federal requirements to prepare for and respond to spills or releases from tanks and other equipment located at these facilities and provide training to employees on operation, maintenance and discharge prevention procedures and the applicable pollution control laws. At such facilities, we have developed or will develop Spill Prevention, Control and Countermeasure plans to memorialize our preparation and response plans and will update them on a regular basis. From time to time, these requirements may be made more stringent and may require us to modify our operations or expand our plans accordingly. The costs of implementing any such modifications or expansion may be significant. In addition, in the event of a spill or release, we may incur fines or penalties or incur responsibility for damage to natural resources, private property or personal injury in addition to obligations to respond to and remediate any such spill or release.

Endangered Species Act

The federal Endangered Species Act, as amended (the “ESA”), restricts activities that may affect endangered and threatened species or their habitats. Although some of our facilities may be located in areas that are designated as habitats for endangered or threatened species, we believe that we are in substantial compliance with the ESA. Some of our suppliers may source materials from locations that provide habitats for species that are protected under the ESA, which may extend the time required to access those areas, or may impose conditions or restrictions on accessing those areas in a way that restricts our access to raw materials. Moreover, as a result of a settlement approved by the U.S.

District Court for the District of Columbia on September 9, 2011, the U.S. Fish and Wildlife Service is required to make a determination regarding the listing of more than 250 species by the end of the agency’s 2017 fiscal year. That process reportedly remains underway. The designation of previously unidentified endangered or threatened species could cause us to incur additional costs or become subject to operating restrictions or bans in the affected areas, which could have an adverse impact on the availability or price of raw materials.

Coastal Area Protection and Wetlands and Navigable Waters Activity Regulations

Our terminals are located in areas that are subject to the various federal and state programs that regulate the conservation and development of coastal resources. At the federal level, the Coastal Zone Management Act (the “CZMA”) was enacted to preserve, protect, develop and, where possible, restore or enhance valuable natural coastal resources of the U.S. coastal zone. The CZMA authorizes and provides grants for state management programs to regulate land and water use and coastal development.  Requirements under the CZMA may affect the siting of any new terminals and could impact the expansion of modification of existing terminal facilities. The CZMA process may result either in delays in obtaining the required authorizations to construct a new terminal or expand an existing terminal or conditions that may restrict the construction or operation of our terminals.

In addition to the CZMA, requirements under the Clean Water Act and related federal laws may result in federal or state regulators imposing conditions or restrictions on our operations or construction activities. For instance, the dredge and fill provisions of the Clean Water Act require a permit to conduct construction activities in protected waters and wetlands and prohibit unpermitted discharges of fill materials. Likewise, the Rivers and Harbors Act requires permits for the construction of certain port structures. We believe that we are in material compliance with these various requirements; however, any delays in obtaining future permits or renewals, or the inclusion of restrictive conditions in such permits, could adversely affect the cost of, or result in delays to, our operations and the construction of new, or expansion of existing, terminals.

Safety and Maintenance

We are subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act, as amended (“OSHA”), and comparable state statutes, whose purpose is to protect the health and safety of workers. We have a corporate health and safety program that governs the way we conduct our operations at our facilities. Our employees receive OSHA training that is appropriate in light of the tasks performed at our facilities and general training on our health and safety plans. Compliance with OSHA and general training is mandatory. We perform preventive and routine maintenance on all of our manufacturing and deep‑water marine terminaling systems, and make repairs and replacements when necessary or appropriate. We also conduct routine and required inspections of those assets in accordance with applicable regulations. In addition, the OSHA hazard communication standards in the Emergency Planning and Community Right‑to‑Know Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in our operations and that this information be provided to employees, state and local governmental authorities and citizens. Our facilities adhere to National Fire Protection Association (NFPA) standards for combustible dust and incorporate pollution control equipment such as cyclones, baghouses and electrostatic precipitators to minimize regulated emissions. Our deep‑water marine terminals adhere to Homeland Security/U.S. Coast Guard regulations regarding physical security and emergency response plans. We continually strive to maintain compliance with applicable air, solid waste and wastewater regulations; nevertheless, we cannot guarantee that serious accidents will not occur in the future.

Seasonality

Our business is affected to some extent by seasonal fluctuations. The cost of producing wood pellets tends to be higher in the winter months because the delivered cost of fiber typically increases with wet weather and our raw materials have, on average, higher moisture content during this period of the year, resulting in a lower product yield. In addition, lower ambient temperatures increase the cost of drying wood fiber. Seasonality may also impact the availability and pricing of limited-scope wood pellet purchase and sale transactions. For example, colder periods typically drive increased demand for wood pellets in the heating and industrial markets, which can increase pricing for prompt deliveries, while warmer periods typically have the opposite effect.

Principal Executive Offices

We lease office space for our principal executive offices at 7200 Wisconsin Avenue, Suite 1000, Bethesda, Maryland 20814. The lease expires in June 2024.

ITEM 1A.  RISK FACTORS

There are many factors that could have a material adverse effect on the Partnership’s business, financial condition, results of operations and cash available for distribution. New risks may emerge at any time, and the Partnership cannot predict those risks or estimate the extent to which they may affect financial performance. Each of the risks described below could adversely impact the value of the Partnership’s common units.

Risks Inherent in Our Business

We may not have sufficient cash from operations following the establishment of cash reserves and payment of costs and expenses, including cost reimbursements to our General Partner and its affiliates, to enable us to pay quarterly distributions to our unitholders at our current distribution rate.

We may not have sufficient cash each quarter to enable us to pay quarterly distributions at our current distribution rate. The amount of cash we can distribute on our common and subordinated units principally depends upon the amount of cash we generate from our operations, which fluctuates from quarter to quarter based on the following factors, some of which are beyond our control:

In addition, the actual amount of cash we have available for distribution depends on other factors, some of which are beyond our control, including:

The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from making cash distributions during periods when we record net income.

The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from reserves and working capital or other borrowings, and not solely on profitability, which will be affected by non‑cash items. As a result, we may pay cash distributions during periods when we record net losses for financial accounting purposes and may be unable to pay cash distributions during periods when we record net income.

Substantially all of our revenues currently are generated under contracts with four customers, and the loss of any of them could adversely affect our business, financial condition, results of operations, cash flows and ability to make cash distributions. We may not be able to renew or obtain new and favorable contracts with these customers when our existing contracts expire, and we may not be able to obtain contracts with new customers, which could adversely affect our revenues and profitability.

Our contracts with Drax, Ørsted, Lynemouth Power and ENGIE will represent substantially all of our sales volumes in 2018. Because we have a small number of customers, we face counterparty concentration risk. The ability of each of our customers to perform its obligations under a contract with us will depend on a number of factors that are beyond our control and may include, among other things, the overall financial condition of the counterparty, the counterparty’s access to capital, the condition of the regional and global power generation industry, continuing

regulatory and economic support for wood pellet‑generated power, spot market pricing trends and general economic conditions. In addition, in depressed market conditions, our customers may no longer need the amount of our products they have contracted for or may be able to obtain comparable products at a lower price. If our customers experience a significant downturn in their business or financial condition, they may attempt to renegotiate, reject or declare force majeure under our contracts. Should any counterparty fail to honor its obligations under a contract with us, we could sustain losses, which could have a material adverse effect on our business, financial condition, results of operations and cash available for distribution. We may also decide to renegotiate our existing contracts on less favorable terms and/or at reduced volumes in order to preserve our relationships with our customers.

Upon the expiration of our off‑take contracts, our customers may decide not to recontract on terms as favorable to us as our current contracts, or at all. For example, our current customers may acquire wood pellets from other providers that offer more competitive pricing or logistics or develop their own sources of wood pellets. Some of our customers could also exit their current business or be acquired by other companies that purchase wood pellets from other providers. The demand for wood pellets or their prevailing prices at the times at which our current off‑take contracts expire may also render entry into new long‑term off‑take contracts difficult or impossible.

Any reduction in the amount of wood pellets purchased by our customers, renegotiation of our contracts on less favorable terms, or our inability to enter into new contracts on economically acceptable terms upon the expiration of our current contracts could have a material adverse effect on our results of operations, business and financial position, as well as our ability to pay distributions to our unitholders.

Termination penalties within our off‑take contracts may not fully compensate us for our total economic losses.

Certain of our off‑take contracts provide the customer with a right of termination for various events of convenience or changes in law or policy. Although some of these contracts are subject to certain protective termination payments, the termination payments made by our customers may not fully compensate us for losses resulting from a termination by such counterparty. In each case, we may be unable to re‑contract our production at favorable prices or at all, and our results of operations, business and financial position, and our ability to make cash distributions to our unitholders may be materially adversely affected as a result.

We derive substantially all of our revenues from customers in Europe. If we fail to diversify our customer base geographically in the future, our results of operations, business and financial position and ability to make cash distributions could be materially adversely affected.

Substantially all of our revenues currently are derived from customers in Europe, and our revenues have been heavily dependent on developments in the European markets. If economic, political, regulatory or financial market conditions in Europe deteriorate, including as a result of weakness in European economies, our customers may respond by suspending, delaying or reducing their expenditures and may attempt to renegotiate, reject or declare force majeure under our contracts. Our failure to successfully penetrate markets outside of Europe in the future could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

The actions of certain special interest groups could adversely impact our business.

Certain special interest groups that focus on environmental issues have expressed their opposition to the use of biomass for power generation, both publicly and directly to domestic and foreign regulators, policy makers, power generators and other industrial users of biomass. These groups are also actively lobbying, litigating and undertaking other actions domestically and abroad in an effort to increase the regulation of, reduce or eliminate the incentives and support for, or otherwise delay, interfere with or impede the production and use of biomass for power generation. Such efforts, if successful, could materially adversely affect our results of operations, business and financial condition, and our ability to make cash distributions to our unitholders.

Our exposure to risks associated with foreign currency and interest rate fluctuations, as well the hedging arrangements we may enter into to mitigate those risks, could have an adverse effect on our financial condition and results of operations.

We may experience foreign currency exchange and interest rate volatility in operating our business. We began to use hedging transactions in 2016 with respect to certain of our off‑take contracts which are, in part or in whole, denominated in British Pound Sterling (“GBP”), as well as an interest rate swap with respect to a portion of our variable rate debt, in an effort to achieve more predictable cash flow and to reduce our exposure to foreign currency exchange and interest rate fluctuations. We currently do not hedge a significant portion of our overall revenue pursuant to our off‑take contracts.

Fluctuations in foreign currency exchange rates could be material to us depending upon, among other things, the currency denominations of our off‑take contracts. In particular, we will in the future have exposure to fluctuations in foreign currency exchange rates between the U.S. Dollar and the GBP as sales under the EVA‑MGT Contract or the 95,000 MTPY contract with the First Hancock JV, which commence in 2019 and 2020, respectively, are denominated in GBP from 2020 onward and sales under the Lynemouth Power Contract, which commenced in 2017, are denominated in U.S. Dollars and GBP. Although the use of hedging transactions limits our downside risk, their use may also limit future revenues.

In addition, there may be instances in which costs and revenue will not be matched with respect to currency denomination. As a result, to the extent that existing and future off‑take contracts are not denominated in U.S. Dollars, it is possible that increasing portions of revenue, costs, assets and liabilities will be subject to fluctuations in foreign currency valuations.

Our hedging transactions involve cost and risk and may not be effective at mitigating our exposure to fluctuations in foreign currency exchange and interest rates. Risks inherent in our hedging transactions include the risk that counterparties to derivative contracts may be unable to perform their obligations and the risk that the terms of such instruments will not be legally enforceable. Likewise, our hedging activities may be ineffective or may not offset more than a portion of the financial impact resulting from foreign currency exchange or interest rates fluctuations, which could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

Challenges to or delays in the issuance of air permits could impair our ability to expand production.

Our pellet production facilities are subject to the requirements of the CAA and must either receive minor source permits from the states in which they are located or a major source permit, which is subject to the approval of the EPA. In general, our facilities are eligible for minor source permits following the application of pollution control technologies. However, should we be subject to any challenges to the issuance of our permits, we could experience substantial delays in the issuance of our permits, which could impair our ability to expand our production capacity. In addition, any new air permits we receive could require that we incur additional expenses to install emissions control technologies or limit operations to satisfy emission limitations.

Changes in laws or government policies, incentives and taxes implemented to support increased generation of or otherwise regulate low‑carbon and renewable energy may affect customer demand for our products.

Consumers of utility‑grade wood pellets currently use our products either as part of a binding obligation to generate a certain percentage of low‑carbon energy or because they receive direct or indirect financial support or incentives to do so. Financial support is often necessary to cover the generally higher costs of wood pellets compared to conventional fossil fuels like coal. In most countries, once the government implements a tax (e.g., the United Kingdom’s carbon price floor tax) or a preferable tariff or a specific renewable energy policy either supporting a renewable energy generator or the energy generating sector as a whole, such tax, tariff or policy is guaranteed for a specified period of time, sometimes for the investment lifetime of any electricity generator’s project. However, governmental policies that

currently support the use of biomass may modify their tax, tariff or incentive regimes, and the future availability of such taxes, tariffs or policies, either in current jurisdictions beyond the prescribed timeframes or in new jurisdictions, is uncertain. Demand for wood pellets could be substantially lower than expected if government support is reduced or delayed or, in the future, is insufficient to enable successful deployment of biomass power to the levels currently projected. In addition, regulatory changes such as new requirements to install additional pollution control technology or curtail operations to meet new GHG emission limits may also affect demand for our products.

In Europe, the European Union’s Renewable Energy Directive (“RED”) requires that it fulfill 20% of its energy demand from renewable sources by 2020. Under the current RED framework, biofuels are subject to a set of sustainability criteria that must be met in order to qualify as renewable fuels. The European Union is currently in the process of finalizing a second Renewable Energy Directive (“RED II”) that seeks to increase the renewable energy goal to 27% of energy demand by 2030. Under the RED II proposal, qualifying biofuels would be subject to new sustainability requirements, including a requirement that biofuel feedstocks be harvested from areas with increasing carbon stocks. The finalization of these requirements could cause us to incur additional compliance costs. Moreover, there can be no guarantee that the final version of RED II will be favorable to biomass producers in the United States. Finally, any actions the European Union takes to regulate biofuels may influence future regulatory actions in other countries where our customers are located. In the event that RED II limits or otherwise constrains our ability to export our product to the European Union or has other adverse consequences, it could have a material adverse effect on our results of operations and financial condition.

In the United States, on October 16, 2017, the EPA proposed a rule to repeal the Clean Power Plan (the “CPP”), the Obama Administration’s rule establishing carbon pollution standards for existing power plants. Under the proposal, the CPP—which is currently subject to a judicial stay issued by the U.S. Supreme Court—would be repealed. The current repeal proposal suggests that the EPA has yet to determine when or whether it might promulgate new GHG emissions standards for existing power plants. At this time, it is not clear what impact the repeal of the CPP and any future rulemaking will have on the demand for biomass in the United States. Also, almost half of U.S. states, either individually or through multi‑state regional initiatives, have begun to address GHG emissions, primarily through the planned development of GHG emission inventories and/or regional GHG cap‑and‑trade programs. Although neither the U.S. Congress nor the states in which our facilities are located have adopted such legislation at this time, they may do so in the future. The adoption of a different approach to the treatment of biogenic carbon in the United States could be treated as precedential by European regulators and impact the regulatory treatment of our product in our primary markets.

Moreover, many nations have agreed to limit emissions of GHGs pursuant to the United Nations Framework Convention on Climate Change and more recently, in December 2015, 195 countries met in Paris, France to approve a landmark climate accord. On November 4, 2016, the Paris Agreement entered into force, potentially providing additional incentives for participating countries to reduce their GHG emissions. While the Trump Administration has signaled its intent to withdraw from the Paris Agreement, substantially all of our current customers are located in countries that have agreed to be bound by the Paris Agreement. Although it is not possible at this time to accurately estimate how potential future laws or regulations addressing GHG emissions would impact our business, any such future laws or implementing regulations could require us to incur increased operating or maintenance costs, which, in turn, could have a material adverse effect on our business, financial condition and results of operations.

The international nature of our business subjects us to a number of risks, including foreign exchange risk and unfavorable political, regulatory and tax conditions in foreign countries.

Substantially all of our current product sales are to customers that operate outside of the United States. As a result, we face certain risks inherent in maintaining international operations that include, but are not limited to, the following:

Our business in foreign countries requires us to respond to rapid changes in market conditions in these countries. Our overall success as a global business depends, in part, on our ability to succeed under differing legal, regulatory, economic, social and political conditions. There can be no assurance, however, that we will be able to develop, implement and maintain policies and strategies that will be effective in each location where our customers operate. Any of the foregoing factors could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

Federal, state and local legislative and regulatory initiatives relating to forestry products and the potential for related litigation could result in increased costs, additional operating restrictions or delays for our suppliers and customers, respectively, which could cause a decline in the demand for our products and negatively impact our business, financial condition and results of operations.

Currently, our raw materials are byproducts of traditional timber harvesting, principally the tops and limbs of trees, as well as other low‑value wood materials that are generated in a harvest and industrial residuals (chips, sawdust and other wood industry byproducts). Commercial forestry is regulated by complex regulatory frameworks at each of the federal, state and local levels. Among other federal laws, the Clean Water Act and the Endangered Species Act have been applied to commercial forestry operations through agency regulations and court decisions, as well as through the delegation to states to implement and monitor compliance with such laws. State forestry laws, as well as land-use regulations and zoning ordinances at the local level, are also used to manage forests in the Southeastern United States, as well as other regions from which we may need to source raw materials in the future. Any new or modified laws or regulations at any of these levels could have the effect of reducing forestry operations in areas where we procure our raw materials and consequently may prevent us from purchasing raw materials in an economic manner, or at all. In addition, future regulation of, or litigation concerning, the use of timberlands, the protection of endangered species, the promotion of forest biodiversity, and the response to and prevention of wildfires, as well as litigation, campaigns or other measures advanced by environmental activist groups, could also reduce the availability of the raw materials required for our operations.

The enactment of derivatives legislation could have an adverse effect on our ability to use derivative instruments to reduce the effect of foreign currency, interest rate, and other risks associated with our business.

The Dodd‑Frank Wall Street Reform and Consumer Protection Act (“Dodd‑Frank Act”) enacted on July 21, 2010, established federal oversight and regulation over the derivatives markets and entities, such as us, that participate in such markets. The Dodd‑Frank Act requires the Commodities Futures Trading Commission (“CFTC”) and the SEC to promulgate rules and regulations implementing the Dodd‑Frank Act. Although the CFTC has finalized certain regulations, others remain to be finalized or implemented and it is not possible at this time to predict when this will be accomplished.

The CFTC has designated certain interest rate swaps and credit default swaps for mandatory clearing and the associated rules also require us, in connection with covered derivative activities, to comply with clearing and trade‑execution requirements or take steps to qualify for an exemption to such requirements. We do not utilize credit default swaps and we qualify for, and expect to continue to qualify for, the end‑user exception from the mandatory clearing requirements for swaps entered to hedge our interest rate risks. Pursuant to the Dodd‑Frank Act, however, the CFTC or federal banking regulators may require the posting of collateral with respect to uncleared interest rate derivative transactions.

Certain banking regulators and the CFTC have recently adopted final rules establishing minimum margin requirements for uncleared swaps. Although we qualify for the end‑user exception from such margin requirements for swaps entered into to hedge our commercial risks, the application of such requirements to other market participants, such

as swap dealers, may change the cost and availability of the swaps that we use for hedging. Moreover, if any of our swaps do not qualify for the commercial end‑user exception, we may be required to post additional cash margin or collateral, which could impact our liquidity and reduce our ability to use cash for capital expenditures or other partnership purposes.

The full impact of the Dodd‑Frank Act and related regulatory requirements upon our business will not be known until the regulations are implemented and the market for derivatives contracts has adjusted. The Dodd‑Frank Act and regulations could significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks we encounter, or reduce our ability to monetize or restructure our existing derivative contracts. If we reduce our use of derivatives as a result of the Dodd‑Frank Act and regulations implementing the Dodd‑Frank Act our results of operations may become more volatile and our cash flows may be less predictable, which could materially adversely affect our ability to plan for and fund capital expenditures.

In addition, the European Union and other non‑U.S. jurisdictions are implementing regulations with respect to the derivatives market. To the extent we transact with counterparties in foreign jurisdictions, we may become subject to such regulations. At this time, the impact of such regulations on us is uncertain.

The vote by the United Kingdom to leave the European Union could adversely affect our results of operations, business and financial position and ability to make cash distributions.

In March 2017, the Prime Minister of the United Kingdom (“U.K.”) formally notified the European Counsel of the commencement of the process by which the United Kingdom will exit (“Brexit”) from the European Union under Article 50 of the Treaty of the European Union. This notification began a two-year period pursuant to which the U.K. and the remaining European Union Member States will negotiate a withdrawal agreement. The United Kingdom is scheduled to withdraw from the European Union in March 2019.

We have take‑or‑pay off‑take contracts with utilities and large power generators in the United Kingdom and in other European markets. For the year ended December 31, 2017, approximately 66% of our product sales were derived from contracts with customers in the United Kingdom and 34% of our product sales were derived from contracts with customers in other European markets.

Brexit may create uncertainty with respect to the legal and regulatory requirements to which we and our customers in the United Kingdom are subject and lead to divergent national laws and regulations as the United Kingdom government determines which European Union laws to replace or replicate. The absence of precedent for an exit of a European Member State from the European Union means that it is unclear how the access of United Kingdom businesses to the European Union Single Market and how the legal and regulatory environments in the United Kingdom and the European Union could be impacted by Brexit, and ultimately how Brexit could impact our business or that of our customers.

The consequences of Brexit, together with what may be protracted negotiations around the terms of Brexit, could also introduce significant uncertainties into global financial markets and adversely impact the markets in which we and our customers operate. For example, prolonged exchange rate volatility or weakness of the local currencies of our customers relative to the U.S. Dollar may impair the purchasing power of our customers and cause them to default on payment or seek modification of the terms of our off‑take contracts. The impacts of Brexit may also adversely affect our ability to re‑negotiate our existing contracts on terms acceptable to us as they expire or enter into new contracts with new or existing customers.

These uncertainties surrounding Brexit and risks associated with the commencement of Brexit could have a material adverse effect on our operations, business and financial position, as well as our ability to pay distributions to our unitholders.

The viability of our customers’ businesses may also affect demand for our products and the results of our business and operations.

The viability of our customers’ businesses is dependent on their ability to compete in their respective electricity and heat markets. Our customers’ competitiveness is a function of, among other things, the market price of electricity, the market price of competing fuels (e.g. coal and natural gas), the relative cost of carbon and the costs of generating heat or electricity using other renewable energy technologies. Changes in the values of the inputs and outputs of our customers’ businesses, or of the businesses of their competitors, could have a material adverse effect on our customers and, as a result, could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

The growth of our business depends in part upon locating and acquiring interests in additional production plants and deep‑water marine terminals at favorable prices.

Our business strategy includes growing our business through drop‑down and third‑party acquisitions that increase our cash generated from operations and cash available for distribution on a per unit basis. Various factors could affect the availability of attractive projects to grow our business, including:

Any of these factors could prevent us from executing our growth strategy or otherwise could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

Any acquisitions we make may reduce, rather than increase, our cash generated from operations on a per unit basis.

We may consummate acquisitions that we believe will be accretive, but result in a decrease in our cash available for distribution per unit. Any acquisition involves potential risks, some of which are beyond our control, including, among other things:

If we consummate any future acquisitions, our capitalization and results of operations may change significantly, and unitholders will not have the opportunity to evaluate the economic, financial and other relevant information that we will consider in determining the application of our funds and other resources.

If there are significant increases in the cost of raw materials or our suppliers suffer from operating or financial difficulties, we could generate lower revenue, operating profits and cash flows or lose our ability to meet commitments to our customers.

We purchase wood fiber from third‑party landowners and other suppliers for use at our production plants. Our reliance on third parties to secure wood fiber exposes us to potential price volatility and unavailability of such raw materials, and the associated costs may exceed our ability to pass through such price increases under our contracts with our customers. Further, delays or disruptions in obtaining wood fiber may result from a number of factors affecting our suppliers, including extreme weather, production or delivery disruptions, inadequate logging capacity, labor disputes, impaired financial condition of a particular supplier, the inability of suppliers to comply with regulatory or sustainability requirements or decreased availability of raw materials. In addition, other companies, whether or not in our industry, could procure wood fiber within our procurement areas and adversely change regional market dynamics, resulting in insufficient quantities of raw material or higher prices. Any of these events could increase our operating costs or prevent us from meeting our commitments to our customers, and thereby could have a material adverse effect on our results of operations, business and financial position, and our ability to make distributions to our unitholders.

Any interruption or delay in the supply of wood fiber, or our inability to obtain wood fiber at acceptable prices in a timely manner, could impair our ability to meet the demands of our customers and expand our operations, which could have a material adverse effect on our results of operations, business and financial position, and our ability to make distributions to our unitholders.

We are exposed to the credit risk of our contract counterparties, including the customers for our products, and any material nonpayment or nonperformance by our customers could adversely affect our financial results and cash available for distribution.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our contract counterparties, including our long-term off-take customers, whose operations are concentrated in the European power generation industry. Our credit procedures and policies may not be adequate to fully eliminate counterparty credit risk. If we fail to adequately assess the creditworthiness of existing or future customers, or if their creditworthiness deteriorates unexpectedly, any resulting unremedied nonpayment or nonperformance by them could have a material adverse effect on our results of operations, business and financial position, and our ability to make cash distributions to our unitholders.

The satisfactory delivery of substantially all of our production is dependent upon continuous access to infrastructure at our owned, leased and third‑party-operated ports. Loss of access to our ports of shipment and destination, including through failure of port equipment and port closures, could adversely affect our financial results and cash available for distribution.

A significant portion of our total production is loaded for shipment utilizing automated conveyor and ship loading equipment at the Port of Chesapeake, Port of Wilmington, and Port Panama City, and substantially all of our

production is dependent upon infrastructure at our owned and third‑party operated ports. Should we suffer a catastrophic failure of the equipment at these ports or otherwise experience port closures, including for security or weather‑related reasons, we could be unable to fulfill off‑take obligations or incur substantial additional transportation costs, which would reduce our cash flow. Moreover, we rely on various ports of destination, as well as third parties who provide stevedoring or other services at our ports of shipment and destination or from whom we charter oceangoing vessels and crews, to transport our product to our customers. Loss of access to these ports for any reason, or failure of such third‑party service providers to uphold their contractual obligations, may impact our ability to fulfill off‑take obligations, cause interruptions to our shipping schedule, and/or cause us to incur substantial additional transportation or other costs, all of which could have a material adverse effect on our business, financial condition and results of operations.

Fluctuations in transportation costs and the availability or reliability of shipping, rail or truck transportation could reduce revenues by causing us to reduce our production or by impairing our ability to deliver products to our customers or the ability of our customers to take delivery of our products.

Disruptions of local or regional transportation services due to shortages of vessels, barges, railcars or trucks, weather‑related problems, flooding, drought, accidents, mechanical difficulties, bankruptcy, strikes, lockouts, bottlenecks or other events could temporarily impair our ability to deliver products to our customers and might, in certain circumstances, constitute a force majeure event under our customer contracts, permitting our customers to suspend taking delivery of and paying for our products.

In addition, persistent disruptions in marine transportation may force us to halt production as we reach storage capacity at our deep‑water marine terminals. Accordingly, if the transportation services we use to transport our products are disrupted, and we are unable to find alternative transportation providers, it could have a material adverse effect on our results of operations, business and financial position, and our ability to make cash distributions to our unitholders.

Our long‑term off‑take contracts with our customers may only partially offset certain increases in our costs or preclude us from taking advantage of relatively high wood prices.

Our long-term off‑take contracts typically set base prices subject to annual price escalation and other pricing adjustments for changes in certain of our underlying costs of operations, including, in some cases, for stumpage or shipping fuel. However, such cost pass‑through mechanisms may only pass a portion of our total costs through to our customers. If our operating costs increase significantly during the terms of our long-term off‑take contracts beyond the levels of pricing and cost protection afforded to us under the terms of such contracts, our results of operations, business and financial position, and ability to make cash distributions to our unitholders could be materially adversely affected.

Moreover, during periods when the price of wood pellets exceeds the prices under our long-term off-take contracts, our revenues could be significantly lower than they otherwise could have been were we not party to such contracts for substantially all of our production. In addition, our current and future competitors may be in a better position than we are to take advantage of relatively high prices during such periods.

We may be required to make substantial capital expenditures to maintain and improve our facilities.

Although we currently use a portion of our cash reserves and cash generated from our operations to maintain, develop and improve our assets and facilities, such investment may, over time, be insufficient to preserve the operating profile required for us to meet our planned profitability or meet the evolving quality and product specifications demanded by our customers. Accordingly, if additional capital expenditures become necessary in the future and we are unable to execute our maintenance or improvement programs successfully and in a timely manner, our results of operations, business and financial position, and our ability to make cash distributions to our unitholders, may be materially adversely affected.

We compete with other wood pellet producers and, if growth in domestic and global demand for wood pellets meets or exceeds management’s expectations, the competition within our industry may grow significantly.

We compete with other wood pellet production companies for the customers to whom we sell our products. Other current producers of utility‑grade wood pellets include AS Graanul Invest, Pinnacle Renewable Energy Inc., Drax Biomass Inc., Georgia Biomass, LLC, Fram Renewable Fuels, LLC, Highland Pellets LLC, Pacific BioEnergy Corporation and The Westervelt Company. Competition in our industry is based on price, consistency and quality of product, site location, distribution and logistics capabilities, customer service, creditworthiness and reliability of supply. Some of our competitors may have greater financial and other resources than we do, may develop technology superior to ours or may have production plants that are sited in more advantageous locations from a transport or other cost perspective.

In addition, we expect global demand for solid biomass to increase significantly in the coming years. This demand growth may lead to a significant increase in the production levels of our existing competitors and may incentivize new, well‑capitalized competitors to enter the industry, both of which could reduce the demand and the prices we are able to obtain under future off‑take contracts. Significant price decreases or reduced demand could have a material adverse effect on our results of operations, business and financial position, and our ability to pay distributions to our unitholders.

For our products to be acceptable to our customers, they must comply with stringent sustainability requirements, which may continue to develop and change.

Biomass energy generation requires the use of biomass that is derived from acceptable sources and is demonstrably sustainable. This typically is implemented through biomass sustainability criteria, which either are a mandatory element of eligibility for financial subsidies to biomass energy generators or will become mandatory in the future. As a biomass fuel supplier, the viability of our business is therefore dependent upon our ability to comply with such requirements. This may restrict the types of biomass we can use and the geographic regions from which we source our raw materials, and may require us to reduce the GHG emissions associated with our supply and production processes. Currently, some elements of the criteria with which we will have to comply, including rules relating to forest management practices, are not yet finalized. If more stringent sustainability requirements are adopted in the future, demand for our products could be materially reduced in certain markets, and our results of operations, business and financial position, and our ability to make cash distributions to our unitholders, may be materially adversely affected as a result.

Our level of indebtedness may increase and reduce our financial flexibility.

As of December 31, 2017, our total debt was $401.0 million, which primarily consisted of $352.2 million outstanding under the Senior Notes and $43.6 million outstanding under the Senior Secured Credit Facilities. In the future, we may incur additional indebtedness in order to make acquisitions or to develop our properties. Our level of indebtedness could affect our operations in several ways, including the following:

In addition, borrowings under the Senior Secured Credit Facilities bear, and potentially other credit facilities we or our subsidiaries may enter into in the future will bear, interest at variable rates. If market interest rates increase, such variable‑rate debt will create higher debt service requirements, which could adversely affect our cash flow.

In addition to our debt service obligations, our operations require substantial expenditures on a continuing basis. Our ability to make scheduled debt payments, to refinance our obligations with respect to our indebtedness and to fund capital and non‑capital expenditures necessary to maintain the condition of our operating assets and properties, as well as to provide capacity for the growth of our business, depends on our financial and operating performance. General economic conditions and financial, business and other factors affect our operations and our future performance. Many of these factors are beyond our control. We may not be able to generate sufficient cash flows to pay the interest on our debt, and future working capital borrowings or equity financing may not be available to pay or refinance such debt.

An increase in the price or a significant interruption in the supply of electricity could have a material adverse effect on our results of operations.

Our production plants use a substantial amount of electricity. The price and supply of electricity are unpredictable and can fluctuate significantly based on international, political and economic circumstances, as well as other events outside our control, such as changes in supply and demand due to weather conditions, regional production patterns and environmental concerns. In addition, potential climate change regulations or carbon or emissions taxes could result in higher production costs for electricity, which may be passed on to us in whole or in part. A significant increase in the price of electricity or an extended interruption in the supply of electricity to our production plants could have a material adverse effect on our results of operations, cash flows and ability to make cash distributions.

Changes in the price of diesel fuel may adversely affect our results of operations.

Diesel fuel costs generally fluctuate with world crude oil prices, and accordingly are subject to political, economic and market factors that are outside of our control. Our operations are dependent on rolling stock and trucks, and diesel fuel costs are a significant component of the operating expense of these vehicles. In addition, diesel fuel is consumed by our wood suppliers in the harvesting and transport of our raw material and is therefore a component of the delivered cost we pay for wood fiber. It is also consumed by the handling equipment at our plants. Some of our off‑take contracts contain mechanisms that are intended to reduce the impact that changes in the price of diesel fuel would have on us, but these mechanisms may not be effective. Accordingly, changes in diesel fuel prices could have an adverse effect on our results of operations, cash flows and ability to make cash distributions.

Our business may suffer if we lose, or are unable to attract and retain, key personnel.

We depend to a large extent on the services of our senior management team and other key personnel. Members of our senior management and other key employees collectively have extensive expertise in designing, building and operating wood pellet production plants, negotiating long‑term off‑take contracts and managing businesses such as ours. Competition for management and key personnel is intense, and the pool of qualified candidates is limited. The loss of any of these individuals or the failure to attract additional personnel, as needed, could have a material adverse effect on our operations and could lead to higher labor costs or the use of less‑qualified personnel. In addition, if any of our executives or other key employees were to join a competitor or form a competing company, we could lose customers, suppliers, know‑how and key personnel. Our success is dependent on our ability to continue to attract, employ and retain highly skilled personnel.

Failure to maintain effective quality control systems at our production plants and deep‑water marine terminals could have a material adverse effect on our business and operations.

Our customers require a reliable supply of wood pellets that meet stringent product specifications. We have built our operations and assets to consistently deliver and certify the highest levels of product quality and performance,

which is critical to the success of our business. These factors depend significantly on the effectiveness of our quality control systems which, in turn, depends on a number of factors. These include the design and efficacy of our quality control systems, the success of our quality training program and our ability to ensure that our employees and third‑party contractors adhere to our quality control policies and guidelines. Any significant failure or deterioration of our quality control systems could impact our ability to deliver product that meets our customers’ specifications and, in turn, could lead to rejection of our product by our customers, which could have a material adverse effect on our business, financial condition, and results of operations.

Our business is subject to operating hazards and other operational risks, which may have a material adverse effect on our business and results of operation. We may also not be adequately insured against such events.

Our business could be adversely affected by operating hazards and other risks to our operations. We produce a combustible product that may under certain circumstances present a risk of fires and explosions or other hazards. Severe weather, such as floods, earthquakes, hurricanes or other natural disasters, climatic phenomena, such as drought, and other catastrophic events, such as plant or shipping disasters, could impact our operations by causing damage to our facilities and equipment, affecting our ability to deliver our product to our customers and impacting our customers’ ability to take delivery of our products. Such events may also adversely affect the ability of our suppliers to provide us with the raw materials we require or the ability of vessels to load, transport and unload our product.

We maintain insurance policies to mitigate against certain risks related to our business, in types and amounts that we believe are reasonable depending on the circumstances surrounding each identified risk; however, we may not be fully insured against all operating hazards and other operational risks incident to our business. Furthermore, we may be unable to maintain or obtain insurance of the type and amount we desire at reasonable rates, if at all. As a result of market conditions and certain claims we may make under our insurance policies, premiums and deductibles for certain of our insurance policies could escalate. In some instances, insurance could become unavailable or available only for reduced amounts of coverage or at unreasonable rates. If we were to incur a significant liability for which we are not fully insured, it could have a material adverse effect on our financial condition, results of operations and cash available for distribution to our unitholders.

Our operations are subject to stringent environmental and occupational health and safety laws and regulations that may expose us to significant costs and liabilities.

Our operations are subject to stringent federal, regional, state and local environmental, health and safety laws and regulations. These laws and regulations govern environmental protection, occupational health and safety, the release or discharge of materials into the environment, air emissions, wastewater discharges, the investigation and remediation of contaminated sites and allocation of liability for cleanup of such sites. These laws and regulations may restrict or impact our business in many ways, including by requiring us to acquire permits or other approvals to conduct regulated activities; limiting our air emissions or wastewater discharges or requiring us to install costly equipment to control, reduce or treat such emissions or discharges; imposing requirements on the handling or disposal of wastes; impacting our ability to modify or expand our operations (for example, by limiting or prohibiting construction and operating activities in environmentally sensitive areas); and imposing health and safety requirements for worker protection. We may be required to make significant capital and operating expenditures to comply with these laws and regulations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of investigatory or remedial obligations, suspension or revocation of permits and the issuance of orders limiting or prohibiting some or all of our operations. Adoption of new or modified environmental laws and regulations may impair the operation of our business, delay or prevent expansion of existing facilities or construction of new facilities and otherwise result in increased costs and liabilities, which may be material.

Our business and operating results are subject to seasonal fluctuations.

Our business is affected to some extent by seasonal fluctuations. The cost of producing wood pellets tends to be higher in colder periods because the delivered cost of fiber typically increases with wet weather and our raw materials have, on average, higher moisture content during such period, resulting in a lower product yield. In addition, lower ambient temperatures increase the cost of drying wood fiber. Seasonality may also impact the availability and pricing of

limited-scope wood pellet purchase and sale transactions. For example, colder periods typically drive increased demand for wood pellets in the heating and industrial markets, which can increase pricing for prompt deliveries, while warmer periods typically have the opposite effect. While our contracts generally call for ratable deliveries throughout the year, we are party to one contract that calls for a higher percentage of deliveries during the first and fourth calendar quarters. These seasonal fluctuations could have an adverse effect on our business, financial condition and results of operations and cause comparisons of operating measures between consecutive quarters may not be as meaningful as comparisons between longer reporting periods.

A terrorist attack or armed conflict could harm our business.

Terrorist activities and armed conflicts could adversely affect the U.S. and global economies and could prevent us from meeting financial and other obligations or prevent our customers from meeting their obligations to us. We could experience loss of business, delays or defaults in payments from customers or disruptions of fuel supplies and markets, including if domestic and global power generators are direct targets or indirect casualties of an act of terror or war. Terrorist activities and the threat of potential terrorist activities and any resulting economic downturn could adversely affect our results of operations, impair our ability to raise capital or otherwise adversely impact our ability to realize certain business strategies.

Risks Related to Our Partnership Structure

Enviva Holdings, LP owns and controls our General Partner, which has sole responsibility for conducting our business and managing our operations. Our General Partner and its affiliates, including Enviva Holdings, LP, have conflicts of interest with us and limited duties, and they may favor their own interests to our detriment and that of our unitholders.

Enviva Holdings, LP, owns and controls our General Partner and appoints all of the directors of our General Partner. Although our General Partner has a duty to manage us in a manner that it believes is not adverse to our interest, the executive officers and directors of our General Partner have a fiduciary duty to manage our General Partner in a manner beneficial to our sponsor. Therefore, conflicts of interest may arise between our sponsor or any of its affiliates, including our General Partner, on the one hand, and us or any of our unitholders, on the other hand. In resolving these conflicts of interest, our General Partner may favor its own interests and the interests of its affiliates over the interests of our common unitholders. These conflicts include the following situations, among others:

In addition, we may compete directly with our sponsor and entities in which it has an interest for acquisition opportunities and potentially will compete with these entities for new business or extensions of the existing services provided by us.

The board of directors of our General Partner may modify or revoke our cash distribution policy at any time at its discretion. Our partnership agreement does not require us to pay any distributions at all.

Pursuant to our cash distribution policy, we intend to distribute quarterly at least $0.4125 per unit on all of our units to the extent we have sufficient cash after the establishment of cash reserves and the payment of our expenses, including payments to our General Partner and its affiliates. However, the board may change such policy at any time at its discretion and could elect not to pay distributions for one or more quarters. Please read Part II, Item 5. “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—Cash Distribution Policy.”

In addition, our partnership agreement does not require us to pay any distributions at all. Accordingly, investors are cautioned not to place undue reliance on the permanence of such a policy in making an investment decision. Any modification or revocation of our cash distribution policy could substantially reduce or eliminate the amounts of distributions to our unitholders. The amount of distributions we make, if any, and the decision to make any distribution at all will be determined by the board of directors of our General Partner, whose interests may differ from those of our common unitholders. Our General Partner has limited duties to our unitholders, which may permit it to favor its own interests or the interests of our sponsor to the detriment of our common unitholders.

Our General Partner limits its liability regarding our obligations.

Our General Partner limits its liability under contractual arrangements between us and third parties so that the counterparties to such arrangements have recourse only against our assets, and not against our General Partner or its assets. Our General Partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our General Partner. Our partnership agreement provides that any action taken by our General Partner to limit its liability is not a breach of our General Partner’s duties, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our General Partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders.

We intend to distribute a significant portion of our cash available for distribution to our partners, which could limit our ability to grow and make acquisitions.

We intend to distribute most of our cash available for distribution, which may cause our growth to proceed at a slower pace than that of businesses that reinvest their cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may impact the cash that we have available to distribute to our unitholders.

Our partnership agreement eliminates and replaces our General Partner’s fiduciary duties to holders of our units.

Our partnership agreement contains provisions that eliminate and replace the fiduciary standards to which our General Partner would otherwise be held by state fiduciary duty law. For example, our partnership agreement permits our General Partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our General Partner, or otherwise free of fiduciary duties to us and our unitholders. This entitles our General Partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our General Partner may make in its individual capacity include:

Limited partners who own common units are treated as having consented to the provisions in the partnership agreement, including the provisions discussed above.

Our partnership agreement restricts the remedies available to holders of our units for actions taken by our General Partner that might otherwise constitute breaches of fiduciary duty.

Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our General Partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our partnership agreement provides that:

In connection with a situation involving a transaction with an affiliate or a conflict of interest, other than one where our General Partner is permitted to act in its sole discretion, any determination by our General Partner must be made in good faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the conflicts committee then it will be presumed that, in making its decision, taking any action or failing to act, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

Our sponsor and other affiliates of our General Partner may compete with us.

Our partnership agreement provides that our General Partner is restricted from engaging in any business activities other than acting as our General Partner, engaging in those activities incidental to its ownership interest in us and providing management, advisory and administrative services to its affiliates or to other persons. However, affiliates of our General Partner, including our sponsor, are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us. In addition, our sponsor may compete with us for investment opportunities and may own an interest in entities that compete with us.

Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our General Partner or any of its affiliates, including its executive officers and directors and our sponsor. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our General Partner and result in less than favorable treatment of us and our unitholders.

The holder or holders of our incentive distribution rights may elect to cause us to issue common units to it in connection with a resetting of the incentive distribution without the approval of our unitholders. This election may result in lower distributions to our common unitholders in certain situations.

The holder or holders of a majority of our incentive distribution rights (currently our General Partner) have the right, at any time when there are no subordinated units outstanding and we have made cash distributions in excess of the then‑applicable third target distribution for each of the prior four consecutive fiscal quarters, to reset the initial target distribution levels at higher levels based on our cash distribution levels at the time of the exercise of the reset election. Following a reset election, a baseline distribution amount will be calculated equal to an amount equal to the prior cash distribution per common unit for the fiscal quarter immediately preceding the reset election (such amount is referred to as the “reset minimum quarterly distribution”), and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterly distribution.

We anticipate that our General Partner would exercise this reset right in order to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cash distributions per unit without such conversion. However, our General Partner may transfer the incentive distribution rights at any time. It is possible that our General Partner or a transferee could exercise this reset election at a time when we are experiencing declines in our aggregate cash distributions or at a time when the holders of the incentive distribution rights expect that we will experience declines in our aggregate cash distributions in the foreseeable future. In such situations, the holders of the incentive distribution rights may be experiencing, or may expect to experience, declines in the cash distributions they receive related to the incentive distribution rights and may therefore desire to be issued our common units, which are entitled to specified priorities with respect to our distributions and which therefore may be more advantageous for them to own in lieu of the right to receive incentive distribution payments based on target distribution levels that are less certain to be achieved. As a result, a reset election may cause our common unitholders to experience dilution in the amount of cash distributions that they would have otherwise received had we not issued new common units to the holders of the incentive distribution rights in connection with resetting the target distribution levels.

Our general partner has certain incentive distribution rights that reduce the amount of our cash available for distribution to our common unitholders.

Our General Partner currently holds incentive distribution rights that entitle it to receive an increasing percentage (15 percent, 25 percent and 50 percent) of the cash that we distribute to our common unitholders from available cash after the minimum quarterly distribution and certain target distribution levels have been achieved. The maximum distribution right for our General Partner to receive 50 percent of any distributions paid to our common unitholders does not include any distributions that our General Partner or its affiliates may receive on common units that they own. Effective as of our quarterly cash distribution in the fourth quarter of 2017, our General Partner was at the top tier of the incentive distribution rights scale. Given that a higher percentage of our cash flows is allocated to our general partner due to these incentive distribution rights, it may be more difficult for us to increase the amount of distributions to our unitholders and our cost of capital may be higher, making investments, capital expenditures and acquisitions, and therefore, future growth, by us potentially more costly, and in some cases, potentially prohibitively so.

Holders of our common units have limited voting rights and are not entitled to elect our General Partner or its directors, which could reduce the price at which our common units will trade.

Compared to the holders of common stock in a corporation, unitholders have limited voting rights and, therefore, limited ability to influence management’s decisions regarding our business. Unitholders have no right on an annual or ongoing basis to elect our General Partner or its board of directors. The board of directors of our General Partner, including the independent directors, is chosen entirely by our sponsor, as a result of it owning our General Partner, and not by our unitholders. Unlike publicly traded corporations, we do not hold annual meetings of our unitholders to elect directors or consider other matters routinely addressed at annual meetings of stockholders of corporations. As a result of these limitations, the price at which the common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

Even if holders of our common units are dissatisfied, they cannot currently remove our General Partner without our sponsor’s consent.

If our unitholders are dissatisfied with the performance of our General Partner, they have limited ability to remove our General Partner. Unitholders are currently unable to remove our General Partner without our sponsor’s consent because our sponsor and its affiliates own sufficient units to be able to prevent its removal. The vote of the holders of at least 662/₃% of all outstanding common and subordinated units voting together as a single class is required to remove our General Partner. As of February 16, 2018, our sponsor owned approximately 50% of our common and subordinated units, taken together. In addition, any vote to remove our General Partner during the subordination period must provide for the election of a successor General Partner by the holders of a majority of the common units and a majority of the subordinated units, voting as separate classes. Both of these conditions provide our sponsor the ability to prevent the removal of our General Partner.

Our general partner interest or the control of our General Partner may be transferred to a third party without unitholder consent.

Our General Partner may transfer its general partner interest to a third party without the consent of our unitholders. Furthermore, our partnership agreement does not restrict the ability of the owner of our General Partner to transfer its membership interests in our General Partner to a third party. The new owner of our General Partner would then be in a position to replace the board of directors and executive officers of our General Partner with its own designees and thereby exert significant control over the decisions taken by the board of directors and executive officers of our General Partner. This effectively permits a “change of control” without the vote or consent of the unitholders.

The incentive distribution rights may be transferred to a third party without unitholder consent.

Our General Partner may transfer the incentive distribution rights to a third party at any time without the consent of our unitholders. If our General Partner transfers the incentive distribution rights to a third party, our General Partner would not have the same incentive to grow our partnership and increase quarterly distributions to unitholders over time. For example, a transfer of incentive distribution rights by our General Partner could reduce the likelihood of our sponsor accepting offers made by us relating to assets owned by our sponsor, as it would have less of an economic incentive to grow our business, which in turn would impact our ability to grow our asset base.

Our General Partner has a call right that may require unitholders to sell their common units at an undesirable time or price.

If at any time our General Partner and its affiliates own more than 80% of the common units, our General Partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price equal to the greater of (1) the average of the daily closing price of the common units over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (2) the highest per‑unit price paid by our General Partner or any of its affiliates for common units during the 90‑day period preceding the date such notice is first mailed. As a result, unitholders may be required to sell their common units at an undesirable time or price and may not receive any return or a negative return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our General Partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the call right. There is no restriction in our partnership agreement that prevents our General Partner from causing us to issue additional common units and then exercising its call right. If our General Partner exercised its call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Exchange Act.

We may issue additional units without unitholder approval, which would dilute existing unitholder ownership interests.

Our partnership agreement does not limit the number of additional limited partner interests we may issue at any time without the approval of our unitholders. The issuance of additional common units or other equity interests of equal or senior rank will have the following effects:

There are no limitations in our partnership agreement on our ability to issue units ranking senior to the common units.

In accordance with Delaware law and the provisions of our partnership agreement, we may issue additional partnership interests that are senior to the common units in right of distribution, liquidation and voting. The issuance by us of units of senior rank may (i) reduce or eliminate the amount of cash available for distribution to our common unitholders; (ii) diminish the relative voting strength of the total common units outstanding as a class; or (iii) subordinate the claims of the common unitholders to our assets in the event of our liquidation.

The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public or private markets, including sales by our sponsor or other large holders.

All of the subordinated units will convert into common units on a one‑for‑one basis at the end of the subordination period, which is expected to occur in May 2018. Our sponsor has registration rights with respect to the common units it currently holds and the common units it will hold upon conversion of the subordinated units. Sales by our sponsor or other large holders of a substantial number of our common units in the public markets, or the perception that such sales might occur, could have a material adverse effect on the price of our common units or could impair our ability to obtain capital through an offering of equity securities.

Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Our partnership agreement restricts unitholders’ voting rights by providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than our General Partner and its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our General Partner, cannot vote on any matter.

Cost reimbursements due to our General Partner and its affiliates for services provided to us or on our behalf will reduce cash available for distribution to our unitholders. The amount and timing of such reimbursements will be determined by our General Partner.

Under our management services agreement with Enviva Management (the “MSA”), we are obligated to reimburse Enviva Management for all direct or indirect costs and expenses incurred by, or chargeable to, Enviva Management in connection with its provision of services necessary for the operation of our business. If the MSA were

terminated without replacement, or our General Partner or its affiliates provided services outside of the scope of the MSA, our partnership agreement would require us to reimburse our General Partner and its affiliates for all expenses they incur and payments they make on our behalf. Our partnership agreement does not set a limit on the amount of expenses for which our General Partner and its affiliates may be reimbursed. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our General Partner by its affiliates. Our partnership agreement provides that our General Partner determines the expenses that are allocable to us. The reimbursement of expenses and payment of fees, if any, to our General Partner and its affiliates will reduce the amount of cash available for distribution to our unitholders.

The price of our common units may fluctuate significantly and unitholders could lose all or part of their investment.

The market price of our common units may be influenced by many factors, some of which are beyond our control, including:

Unitholders may have liability to repay distributions.

Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under Section 17‑607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution to our unitholders if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Liabilities to partners on account of their partnership interests and liabilities that are non‑recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

For as long as we are an emerging growth company, we will not be required to comply with certain disclosure requirements that apply to other public companies.

For as long as we remain an “emerging growth company” as defined in the JOBS Act, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to provide an auditor’s attestation report on management’s assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404 of the Sarbanes‑Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports. We will remain an emerging growth company for up to five years, although we will lose that status earlier if we have more than $1.0 billion of revenues in a fiscal year, have more than $700.0 million in market value of our common units held by non‑affiliates, or issue more than $1.0 billion of non‑convertible debt over a three‑year period.

To the extent that we rely on any of the exemptions available to emerging growth companies, our unitholders will receive less information about our executive compensation and internal control over financial reporting than issuers

that are not emerging growth companies. If some investors find our common units to be less attractive as a result, there may be a less active trading market for our common units and our trading price may be more volatile.

The New York Stock Exchange (the “NYSE”) does not require a publicly traded partnership like us to comply with certain of its corporate governance requirements.

Our common units are listed on the NYSE. Because we are a publicly traded partnership, the NYSE does not require us to have a majority of independent directors on our General Partner’s board of directors or to establish a compensation committee or a nominating and corporate governance committee. Accordingly, unitholders do not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements. Please read Part III, Item 10. “Directors, Executive Officers and Corporate Governance—Director Independence.”

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for federal income tax purposes and not being subject to a material amount of entity‑level taxation. If the Internal Revenue Service (“IRS”) were to treat us as a corporation for federal income tax purposes, or we become subject to entity‑level taxation for state tax purposes, our cash available for distribution to our unitholders would be substantially reduced.

The anticipated after‑tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income tax purposes.

Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a “qualifying income” requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement. We have requested and obtained a favorable private letter ruling from the IRS to the effect that, based on facts presented in the private letter ruling request, our income from processing timber feedstocks into pellets and transporting, storing, marketing and distributing such timber feedstocks and wood pellets constitute “qualifying income” within the meaning of Section 7704 of the Internal Revenue Code of 1986 (the “Code”). However, no ruling has been or will be requested regarding our treatment as a partnership for U.S. federal income tax purposes. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate. Distributions to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses or deductions would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after‑tax return to the unitholders, likely causing a substantial reduction in the value of our common units.

Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity‑level taxation for U.S. federal, state, local or foreign income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law or interpretation on us. At the state level, several states have been evaluating ways to subject partnerships to entity‑level taxation through the imposition of state income, franchise or other forms of taxation. Specifically, we currently own assets and conduct business in Mississippi, North Carolina, Florida and Virginia, each of which imposes a margin or franchise tax. In the future, we may expand our operations. Imposition of a similar tax on us in other jurisdictions that we may expand to could substantially reduce our cash available for distribution to our unitholders.

The tax treatment of publicly traded partnerships or an investment in our units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any

time. From time to time, members of Congress propose and consider substantive changes to the existing U.S. federal income tax laws that affect publicly traded partnerships. Although there is no current legislative proposal, a prior legislative proposal would have eliminated the qualifying income exception to the treatment of all publicly traded partnerships as corporations upon which we rely for our treatment as a partnership for U.S. federal income tax purposes.

In addition, on January 24, 2017, final regulations regarding which activities give rise to qualifying income within the meaning of Section 7704 of the Code (the “Final Regulations”) were published in the Federal Register. The Final Regulations are effective as of January 19, 2017 and apply to taxable years beginning on or after January 19, 2017 and, consistent with our private letter ruling, the Final Regulations generally treat income from the production, transportation and marketing of wood pellets as qualifying income. However, there can be no assurance that there would not be further changes to the Treasury Department’s interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership for U.S. federal income tax purposes.

Any modification to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible for us to meet the exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be enacted. Any such changes could negatively impact the value of an investment in our common units. You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential effect on your investment in our common units.

If the IRS were to contest the federal income tax positions we take, it may adversely impact the market for our common units, and the costs of any such contest would reduce cash available for distribution to our unitholders.

We have requested and obtained a favorable private letter ruling from the IRS to the effect that, based on facts presented in the private letter ruling request, our income from processing timber feedstocks into pellets and transporting, storing, marketing and distributing such timber feedstocks and wood pellets will constitute “qualifying income” within the meaning of Section 7704 of the Internal Revenue Code. However, no ruling has been or will be requested regarding our treatment as a partnership for U.S. federal income tax purposes. The IRS may adopt positions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. Moreover, the costs of any contest between us and the IRS will result in a reduction in cash available for distribution to our unitholders and thus will be borne indirectly by our unitholders.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us, in which case we may require our unitholders and former unitholders to reimburse us for such taxes (including any applicable penalties or interest) or, if we are required to bear such payments, our cash available for distribution to our unitholders might be substantially reduced.

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us. To the extent possible under the new rules, our General Partner may elect to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each unitholder and former unitholder with respect to an audited and adjusted return, which statement reports the items adjusted and certain other amounts. Although our General Partner may elect to have our unitholders and former unitholders take such audit adjustment into account in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties and interest, we may require our unitholders and former unitholders to reimburse us for such taxes (including any applicable penalties or interest) or, if we are required to bear such payments, our cash available for distribution to our unitholders might be substantially reduced. These rules are not applicable for tax years beginning on or prior to December 31, 2017.

Even if unitholders do not receive any cash distributions from us, unitholders will be required to pay taxes on their share of our taxable income.

Unitholders are required to pay federal income taxes and, in some cases, state and local income taxes, on unitholders’ share of our taxable income, whether or not they receive cash distributions from us. For example, if we sell assets and use the proceeds to repay existing debt or fund capital expenditures, you may be allocated taxable income and gain resulting from the sale, and our cash available for distribution would not increase. Similarly, taking advantage of opportunities to reduce our existing debt, such as debt exchanges, debt repurchases, or modifications of our existing debt could result in “cancellation of indebtedness income” being allocated to our unitholders as taxable income without any increase in our cash available for distribution. Unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax due from them with respect to that income.

A tax gain or loss on the disposition of our common units could be more or less than unitholders expect.

If unitholders sell their common units, they will recognize a gain or loss equal to the difference between the amount realized and their tax basis in those common units. Because distributions in excess of unitholders’ allocable share of our net taxable income decrease their tax basis in their common units, the amount, if any, of such prior excess distributions with respect to the units unitholders sell will, in effect, become taxable income to our unitholders if they sell such units at a price greater than their tax basis in those units, even if the price they receive is less than their original cost. In addition, because the amount realized includes a unitholder’s share of our nonrecourse liabilities, if they sell their units, unitholders may incur a tax liability in excess of the amount of cash they receive from the sale.

Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. Thus, you may recognize both ordinary income and capital loss from the sale of your units if the amount realized on a sale of your units is less than your adjusted basis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period in which you sell your units, you may recognize ordinary income from our allocations of income and gain to you prior to the sale and from recapture items that generally cannot be offset by any capital loss recognized upon the sale of units.

Tax‑exempt entities face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in common units by tax‑exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs), raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Further, with respect to taxable years beginning after December 31, 2017, a tax-exempt entity with more than one unrelated trade or business (including by attribution from investment in a partnership such as ours that is engaged in one or more unrelated trade or business) is required to compute the unrelated business taxable income of such tax-exempt entity separately with respect to each such trade or business (including for purposes of determining any net operating loss deduction). As a result, for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our partnership to offset unrelated business taxable income from another unrelated trade or business and vice versa. Any tax‑exempt entity should consult their tax advisor before investing in our common units.

Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.

Historically, we have been entitled to a full deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, under the Tax Cuts and Jobs Act signed into law in December 2017, for taxable years beginning after December 31, 2017, our deduction for “business interest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.” For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, amortization or depletion.

Non-U.S. Unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.

Non-U.S. unitholders are generally taxed and subject to income tax filing requirements by the United States on income effectively connected with a U.S. trade or business (“effectively connected income”). Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be “effectively connected” with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate and a non-U.S. unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the sale or disposition of such unit. 

The Tax Cuts and Jobs Act imposes a withholding obligation of 10% of the amount realized upon a non-U.S. unitholder’s sale or exchange of an interest in a partnership that is engaged in a U.S. trade or business. However, due to challenges of administering a withholding obligation applicable to open market trading and other complications, the IRS has temporarily suspended the application of this withholding rule to open market transfers of interests in publicly traded partnerships pending promulgation of regulations or other guidance that resolves the challenges. It is not clear if or when such regulations or other guidance will be issued. Non-U.S. unitholders should consult a tax advisor before investing in our common units.

We treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units, we have adopted certain methods for allocating depreciation and amortization deductions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to the use of those methods could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from our unitholders’ sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to their tax returns.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month (the “Allocation Date”), instead of on the basis of the date a particular unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital additions, gain or loss realized on a sale or other disposition of our assets and, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of our proration method. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of units) may be considered as having disposed of those units. If so, he would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.

Because there are no specific rules governing the U.S. federal income tax consequence of loaning a partnership interest, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a

securities loan are urged to consult a tax advisor to determine whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.

We have adopted certain valuation methodologies in determining a unitholder’s allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, which could adversely affect the value of the common units.

In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may, from time to time, consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

A successful IRS challenge to these methods or allocations could adversely affect the timing or amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain from our unitholders’ sale of common units and could have a negative impact on the value of the common units or result in audit adjustments to our unitholders’ tax returns without the benefit of additional deductions.

Our unitholders will likely be subject to state and local taxes and income tax return filing requirements in jurisdictions where they do not live as a result of investing in our common units.

In addition to U.S. federal income taxes, our unitholders may be subject to other taxes, including foreign, state and local taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if they do not live in any of those jurisdictions. Our unitholders will likely be required to file foreign, state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those requirements.

We currently own assets in multiple states. Many of these states currently impose a personal income tax on individuals, corporations and other entities. As we make acquisitions or expand our business, we may own assets or conduct business in additional states that impose a personal income tax. It is our unitholders’ responsibility to file all U.S. federal, foreign, state and local tax returns.

None.

ITEM 2.  PROPERTIES

Information regarding our properties is contained in Part I, Item 1. “Business” and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

ITEM 3.  LEGAL PROCEEDINGS

During the fourth quarter of 2016, we re‑purchased a shipment of wood pellets from one customer and subsequently sold it to a different customer in a back‑to‑back transaction. Smoldering was observed onboard the vessel carrying the shipment, which resulted in damage to a portion of the shipment and one of the vessel’s five cargo holds (the “Shipping Event”). The disponent owner of the vessel (the “Shipowner”) had directly or indirectly chartered the vessel from certain other parties (collectively, the “Head Owners”) and in turn contracted with Cottondale as the charterer of the vessel. Following the mutual appointment of arbitrators in connection with the Shipping Event, on June 8, 2017, the Shipowner submitted claims against Cottondale (the “Claims”) alleging damages of approximately $11.8 million (calculated using exchange rates as of December 31, 2017), together with other unquantified losses and damages. The Claims provide that the Shipowner would seek indemnification and other damages from Cottondale to the extent

that the Shipowner is unsuccessful in its defense of claims raised by the Head Owners against it for damages arising in connection with the Shipping Event.

Although it is reasonably possible that the Shipping Event may result in additional costs and liabilities for our account, responsibility for such costs and liabilities incurred in connection with the Shipping Event is disputed among the various parties involved. If any such costs and liabilities ultimately are allocated to us, a portion may be recovered under insurance. We believe we have meritorious defenses to the Claims, but we are generally unable to predict the timing or outcome of any claims or proceedings, including the Claims, associated with the Shipping Event, or any insurance recoveries in respect thereof. Consequently, we are unable to provide an estimate of the amount or range of possible loss.

ITEM 5.  MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information

Our common units representing limited partner interests in the Partnership (“common units”) are traded on the New York Stock Exchange (“NYSE”) under the symbol “EVA.” The following tables set forth the range of high and low sales prices per unit for our common units, as reported by the NYSE, and the quarterly cash distributions for the indicated periods:

As of February 16, 2018, there were 14,445,268 common units outstanding held by three unitholders of record. Because many of our common units are held by brokers and other institutions on behalf of unitholders, we are unable to estimate the total number of unitholders represented by these unitholders of record. As of February 16, 2018, we also had 11,905,138 subordinated units outstanding. There is no established public market in which the subordinated units are traded. As of February 16, 2018, our sponsor held approximately 9% of the common units and all of the subordinated units.

Cash Distribution Policy

General

Our partnership agreement provides that our General Partner will make a determination as to whether to make a distribution, but our partnership agreement does not require us to pay distributions at any time or in any amount. Instead, the board of directors of our General Partner adopted a cash distribution policy that sets forth our General Partner’s intention with respect to the distributions to be made to unitholders. Pursuant to our cash distribution policy, within 60 days after the end of each quarter, we intend to distribute to the holders of common and subordinated units on a quarterly basis at least the minimum quarterly distribution of $0.4125 per unit, or $1.65 on an annualized basis, to the extent we have sufficient cash after establishment of cash reserves and payment of fees and expenses, including payments to our General Partner and its affiliates.

The board of directors of our General Partner may change the foregoing distribution policy at any time and from time to time, and even if our cash distribution policy is not modified or revoked, the amount of distributions paid under our policy and the decision to make any distribution is determined by our General Partner. Our partnership agreement does not contain a requirement for us to pay distributions to our unitholders, and there is no guarantee that we will pay any specific distribution level, or any distribution, on the units in any quarter. However, our partnership agreement does contain provisions intended to motivate our General Partner to make steady, increasing and sustainable distributions over time.

Please read Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Senior Secured Credit Facilities” for a discussion of the provisions included in our credit facility that may restrict our ability to make distributions.

Subordination Period

Our partnership agreement provides that, during the subordination period, holders of our common units have the right to receive distributions from operating surplus (as defined in our partnership agreement) each quarter in an amount equal to $0.4125 per common unit, which amount is defined in our partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions from operating surplus may be made to holders of the subordinated units. These units are deemed “subordinated” because for a period of time, referred to as the subordination period, the subordinated units will not be entitled to receive any distributions from operating surplus until the common units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly distribution from prior quarters. Furthermore, no arrearages will be paid on the subordinated units. We expect the subordination period to expire in May 2018, at which time all of the subordinated units will convert into common units on a one‑for‑one basis.

General Partner Interest and Incentive Distribution Rights

Our General Partner owns a non‑economic general partner interest in us, which does not entitle it to receive cash distributions. However, our General Partner owns the incentive distribution rights and may in the future own common units or other equity interests in us and will be entitled to receive distributions on any such interests.

Incentive distribution rights represent the right to receive increasing percentages (15.0%, 25.0% and 50.0%) of quarterly distributions from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Our General Partner currently holds the incentive distribution rights, but may transfer these rights separately from its general partner interest.
