Enviva Partners, LP Reports Strong Financial Results for Full-Year 2016 and Affirms 2017 Guidance

BETHESDA, MD, February 23, 2017 — Enviva Partners, LP (NYSE: EVA) (the “Partnership” or “we”) today reported financial and operating results for the fourth quarter and full-year 2016.

Highlights:

·                  Completed the Sampson Drop-Down acquisition on December 14, 2016

·                  Generated net revenue of $464.3 million and net income of $17.7 million for the full-year 2016, after giving effect to the recast for the Sampson Drop-Down

·                  Excluding the results of the Sampson Drop-Down for the period prior to the Acquisition Date, generated adjusted EBITDA of $89.6 million for the full-year 2016

·                  Affirming full-year 2017 guidance for net income in a range of $31.0 million to $35.0 million and adjusted EBITDA in a range of $110.0 million to $114.0 million, excluding the impact of any additional drop-downs or third-party acquisitions

“Strong plant performance and reduced costs across our operations enabled the partnership to deliver solid financial results for the year,” said John Keppler, Chairman and Chief Executive Officer.  “We completed the Sampson drop-down acquisition earlier than anticipated, setting the stage for robust growth in 2017.”

Presentation of Recast Financial Results

On December 14, 2016 (the “Acquisition Date”), we consummated the acquisition of all of the issued and outstanding limited liability company interests in Enviva Pellets Sampson, LLC (“Sampson”).  The acquisition consisted of a fully operational wood pellet production plant in Sampson County, North Carolina (the “Sampson Plant”), a 10-year, 420,000 metric tons per year (“MTPY”) off-take contract with DONG Energy Thermal Power A/S (“DONG Energy”), a 15-year, 95,000 MTPY off-take contract with our sponsor’s joint venture, and related third-party shipping contracts (collectively, the “Sampson Drop-Down”).  Because the Sampson Drop-Down was a transfer between entities under common control, generally accepted accounting principles in the United States (“GAAP”) require that we recast our financial results to include the results of the Sampson Drop-Down since the date Sampson was originally organized.  In addition, certain intercompany transactions between us and Sampson during such periods have been eliminated and the results are presented as if the assets included in the Sampson Drop-Down had been the Partnership’s assets since Sampson was initially organized.  As a result, Sampson’s results are now included in our results presented in accordance with GAAP.  The effect of this recast is to present financial statements as if the Partnership had developed the Sampson plant when in fact it is our sponsor’s strategy to develop new projects outside the Partnership.  Unless otherwise indicated, the financial results presented in this release are recast on this basis.

Annual Financial Results

For the full-year 2016, we generated net revenue of $464.3 million, an increase of 1.5 percent, or $6.9 million, from 2015.  Included in net revenue were product sales of $444.5 million during 2016 and $451.0 million during 2015.  Other revenue increased to $19.8 million in 2016 from $6.4 million for 2015, principally due to increased fees earned related to customer requests to adjust the timing of or cancel shipments.  We generated net income of $17.7 million in 2016 compared to $19.5 million last year, a decrease of $1.7 million, driven principally by a $10.0 million non-cash impairment charge associated with the planned sale of our smallest production plant located in Wiggins, Mississippi, and higher interest expense.

Excluding the results of the Sampson Drop-Down for the period prior to the Acquisition Date, adjusted EBITDA for 2016 was $89.6 million, an increase of 16.0 percent, or $12.4 million, from 2015.  The increase in adjusted EBITDA was driven by increased other revenue and cost improvements across our operations during 2016, primarily related to increased plant utilization, lower raw material costs and lower fuel costs that reduced our to-port logistics costs.  Distributable cash flow, prior to any distributions attributable to incentive distribution rights paid to the general partner, was $68.8 million.

Fourth Quarter Financial Results

For the fourth quarter of 2016, we generated net revenue of $126.5 million, an increase of 8.3 percent, or $9.7 million, from the corresponding quarter of 2015.  Included in net revenue were product sales of $121.2 million, an increase of $6.1 million from the corresponding quarter of last year due to an increased number of shipments under CIF contracts, which had the effect of increasing revenue and cost of sales, as well as favorable contract pricing mix.  We had a net loss of $8.1 million compared to net income of $7.6 million for the fourth quarter of 2015, a decrease of $15.7 million, driven by the non-cash impairment charge mentioned above and an increase in interest expense.

Excluding the results of the Sampson Drop-Down for the period prior to the Acquisition Date, adjusted EBITDA for the fourth quarter of 2016 was $22.2 million, an increase of 3.1 percent, or $0.7 million, from the corresponding period in 2015.  The increase in adjusted EBITDA was driven by increased product sales and lower raw material costs.  Distributable cash flow, prior to any distributions attributable to incentive distribution rights paid to the general partner, was $12.9 million.

Distribution

As announced February 1, 2017, the board of directors of our general partner declared a distribution of $0.5350 per common and subordinated unit for the fourth quarter of 2016.  This distribution is 16.3 percent higher than the distribution for the fourth quarter of 2015.  The quarterly distribution will be paid on Tuesday, February 28, 2017, to unitholders of record as of the close of business on Wednesday, February 15, 2017.

Including the fourth quarter distribution, the Partnership will have distributed $2.10 per common and subordinated unit for full-year 2016.  The Partnership’s distributable cash flow, excluding the results of the Sampson Drop-Down for the period prior to the Acquisition Date and net of amounts attributable to incentive distribution rights, was $67.8 million for 2016, resulting in a distribution coverage ratio of 1.28 times.

Outlook and Guidance

Consistent with the guidance provided on November 3, 2016, the Partnership expects full-year 2017 net income to be in the range of $31.0 million to $35.0 million and adjusted EBITDA to be in the range of $110.0 million to $114.0 million.  The Partnership expects to incur maintenance capital expenditures of $5.0 million and interest expense net of amortization of debt issuance costs and original issue discount of $29.0 million in 2017.  As a result, the Partnership expects full-year distributable cash flow to be in the range of $76.0 million to $80.0 million, prior to any distributions attributable to incentive distribution rights paid to the general partner.  For full-year 2017, we expect to distribute at least $2.35 per common and subordinated unit.  The guidance amounts provided above do not include the impact of any additional acquisitions from the Partnership’s sponsor or third parties.  Although deliveries to our customers are generally ratable over the year, the Partnership’s quarterly income and cash flow are subject to modest seasonality in the first quarter and to the mix of customer shipments made, which may vary from period to period.  As such, the board of directors of the Partnership’s general partner evaluates the Partnership’s distribution coverage ratio on an annual basis when determining the distribution for a quarter.

Market and Contracting Update

Our sales strategy is to fully contract the production capacity of the Partnership.  Our current capacity is matched with a portfolio of off-take contracts that has a weighted-average remaining term of 9.8 years from February 1, 2017.

Independent industry experts Hawkins Wright project that worldwide demand for industrial wood pellets will increase to approximately 27 million tons in 2020, representing an annual growth rate of nearly 20 percent, driven predominantly by biomass consumption in Europe and Asia.  The following are key recent developments:

·                  DONG Energy, the largest power producer in Denmark, announced in February 2017 that it will completely eliminate the use of coal in its generation of power and heat by 2023, and will replace the fuel with biomass.  DONG Energy already has two facilities burning wood pellets, which are expected to consume approximately 1.8 million MTPY of wood pellets at full capacity.

·                  In December, Drax Power Limited (“Drax”) received EU state-aid approval of the contract for difference (CfD) through 2027 for its third 660 megawatt (“MW”) biomass unit, which is anticipated to require more than 2 million MTPY of wood pellets.  Drax has stated that it could convert the remaining three coal-burning units to biomass in the next two to three years under the right conditions.

·                  In the Netherlands, biomass projects were awarded the majority of the 5.0 billion euros in funding available through the second and final round of applications for the 2016 renewable incentive program, including 2.1 billion euros awarded to coal plants planning to co-fire biomass.  Both rounds in 2016 were heavily oversubscribed, and RWE, Engie, and Uniper received awards.  The Minister of Economic Affairs has announced that the program budget will be increased from 9.0 billion euros in 2016 to 12.0 billion euros in 2017.

·                  In November, Japan ratified the Paris climate agreement, demonstrating the government’s commitment to reducing carbon emissions.  As part of their plan for significant emissions reductions by 2030, Japan has set a target of 6.0 — 7.5 gigawatts (“GWs”) of biomass-fired

3

capacity, of which nearly 3.2 GWs have been approved through Japan’s feed-in tariff (FiT) program with many other projects that are either awaiting approval or expected to apply prior to the September deadline for the 2017 award applications.  Several power producers have announced biomass projects, including Japan’s largest electricity wholesaler, Electric Power Development Company (J-Power), which stated recently it expects to co-fire biomass at all seven of its coal-fired plants.

·                  Several recently announced biomass-fueled projects in South Korea are expected to be operational by 2020, increasing the expected South Korean demand for wood pellets up to 6 million MTPY.  As this demand is well in excess of expected domestic supply, a significant amount of wood pellets are expected to be imported under long-term contracts, representing a shift from the short-term tender mechanism currently used to purchase biomass in South Korea.

·                  In January, China’s National Energy Administration announced that the country will spend at least $360.0 billion on renewable energy through 2030.  In addition, published reports indicate that China is expected to increase biomass-fired generation capacity from 10.3 GWs in 2015 to 15.0 GWs by 2020.

Sponsor Activity

Construction of our sponsor’s deep-water marine terminal in Wilmington, North Carolina (the “Wilmington terminal”) is complete.  The first shipment was loaded in December 2016, the facility receives regular deliveries via truck and rail, and routinely loads vessels consistent with our sponsor’s expectations.  The Partnership expects to have the opportunity to acquire the Wilmington terminal in 2017.

Our sponsor’s joint venture is currently completing the detailed design for a build-and-copy replica of the Sampson plant at a permitted site in Hamlet, North Carolina, to supply MGT Power’s Teesside Renewable Energy Plant.  In order to supply anticipated incremental volume growth in Europe and the emerging Asian market, our sponsor is also evaluating additional production capacity investments at its sites in Lucedale, Mississippi and Abbeville, Alabama, as well as other sites positioned to take advantage of the existing terminal capacity at our Port of Chesapeake and the Port of Wilmington.  In addition, our sponsor continues to evaluate its option to build and operate a marine export terminal at the Port of Pascagoula, Mississippi, which could support pellet production from the potential plant in Lucedale, Mississippi and other potential facilities in the region.

Conference Call

We will host a conference call with executive management related to our fourth quarter and full-year 2016 results and to discuss our outlook and guidance, and a more detailed market update, at 10:00 a.m. (Eastern Time) on Thursday, February 23, 2017.  Information on how interested parties may listen to the conference call is available in the Investor Relations page of our website (www.envivabiomass.com).  A replay of the conference call will be available on our website after the live call concludes.

Non-GAAP Financial Measures

We provide results in this release that (i) do not give effect to the recast of financial results and assume the Sampson Drop-Down had not occurred or (ii) include financial results of assets excluding the period prior to the Acquisition Date.  These illustrative presentations are not presented in accordance with GAAP and should not be considered alternatives to the presentation of the recast financial results of the Partnership. Management views these presentations as important to reflect the Partnership’s actual performance during 2016, including as measured against our published guidance for 2016, which did not include the impact of acquisitions.

We use adjusted gross margin per metric ton, adjusted EBITDA and distributable cash flow to measure our financial performance.

Adjusted Gross Margin per Metric Ton

We define adjusted gross margin as gross margin excluding depreciation and amortization included in cost of goods sold.  We believe adjusted gross margin per metric ton is a meaningful measure because it compares our revenue-generating activities to our operating costs for a view of profitability and performance on a per metric ton basis.  Adjusted gross margin per metric ton will be affected primarily by our ability to meet targeted production volumes and to control direct and indirect costs associated with procurement and delivery of wood fiber to our production plants and the production and distribution of wood pellets.

Adjusted EBITDA

We define adjusted EBITDA as net income or loss excluding depreciation and amortization, interest expense, income tax expense, early retirement of debt obligations, non-cash unit compensation expense, asset impairments and disposals and certain items of income or loss that we characterize as unrepresentative of our ongoing operations.  Adjusted EBITDA is a supplemental measure used by our management and other users of our financial statements, such as investors, commercial banks and research analysts, to assess the financial performance of our assets without regard to financing methods or capital structure.

Distributable Cash Flow

We define distributable cash flow as adjusted EBITDA less maintenance capital expenditures and interest expense net of amortization of debt issuance costs and original issue discount.  We use distributable cash flow as a performance metric to compare the cash-generating performance of the Partnership from period to period and to compare the cash-generating performance for specific periods to the cash distributions (if any) that are expected to be paid to our unitholders.  We do not rely on distributable cash flow as a liquidity measure.

Adjusted gross margin per metric ton, adjusted EBITDA, and distributable cash flow are not financial measures presented in accordance with GAAP.  We believe that the presentation of these non-GAAP financial measures provides useful information to investors in assessing our financial condition and results of operations.  Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measures.  Each of these non-GAAP financial measures has important limitations as an analytical tool because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures.  You should not consider adjusted gross margin per metric ton, adjusted EBITDA, or distributable cash flow in

6

isolation or as substitutes for analysis of our results as reported under GAAP.  Our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.
