AMERICAN DG ENERGY INC.


PART I

Item 1. Business.

General

American DG Energy Inc., or the Company, we, our, or us, distributes, owns and operates clean, on-site energy systems that produce electricity, hot water, heat and cooling. Our business model is to own the equipment that we install at customers' facilities and to sell the energy produced by these systems to the customer on a long-term contractual basis. We call this business the “On-Site Utility”.
We offer natural gas powered cogeneration systems that are reliable and energy efficient. Our cogeneration systems produce electricity from an internal combustion engine driving a generator, while the heat from the engine and exhaust is recovered and typically used to produce heat and hot water for use at the site. We also distribute and operate water chiller systems for building cooling applications that operate in a similar manner, except that the engine's power drives a large air-conditioning compressor while recovering heat for hot water. Cogeneration systems reduce the amount of electricity that the customer must purchase from the local utility and produce valuable heat and hot water for the site to use as required. By simultaneously providing electricity, hot water and heat, cogeneration systems also have a significant, positive impact on the environment by reducing the carbon dioxide or CO2, produced by replacing a portion of the traditional energy supplied by the electric grid and conventional hot water boilers.
Distributed generation of electricity (DG), often referred to as cogeneration systems, or combined heat and power systems (CHP), is an attractive option for reducing energy costs and increasing the reliability of available energy. DG has been successfully implemented by others in large industrial installations over 10 Megawatts (MW), where the market has been growing for a number of years, and is increasingly being accepted in smaller size units because of technology improvements, increased energy costs and better DG economics. We believe that our target market (users of up to 1 MW) has been barely penetrated and that the reduced reliability of the utility grid, increasing cost pressures experienced by energy users, advances in new, low cost technologies and DG-favorable legislation and regulation at the state and federal level will drive our near-term growth and penetration of the target market. The Company maintains a website at www.americandg.com, but our website address included in this Annual Report is a textual reference only, and the information in the website is not incorporated by reference into this Annual Report.
The Company was incorporated as a Delaware corporation on July 24, 2001 to install, own, operate and maintain complete DG systems, or energy systems, and other complementary systems at customer sites and sell electricity, hot water, heat and cooling energy under long-term contracts at prices guaranteed to the customer to be below conventional utility rates. As of December 31, 2014, we had installed energy systems, representing an aggregate of approximately 8,186 kilowatts, or kW, 60.0 million British thermal units, or MMBtu's, of heat and hot water and 4,525 tons of cooling. kW is a measure of electricity generated, MMBtu is a measure of heat generated and a ton is a measure of cooling generated. Due to the high efficiency of CHP systems, the Environmental Protection Agency (EPA), has recognized CHP as a means to improve the environment.
We believe that our primary near-term opportunity for DG energy and equipment sales is where commercial electricity rates exceed $0.12 per kW hour, or kWh, which is predominantly in the Northeast and California. Attractive DG economics are currently attainable in applications that include hospitals, nursing homes, multi-tenant residential housing, hotels, schools and colleges, recreational facilities, food processing plants, dairies and other light industrial facilities.
We believe that the largest number of potential DG users in the U.S. require less than 1 MW of electric power and less than 1,200 tons of cooling capacity. We are able to design our systems to suit a particular customer's needs because of our ability to place multiple units at a site. This approach is part of what allows our products and services to meet changing power and cooling demands throughout the day (also from season-to-season) and greatly improves efficiency.
American DG Energy purchases energy equipment from various suppliers. The primary type of equipment used is a natural gas-powered, reciprocating engine provided by Tecogen Inc., or Tecogen, an affiliate of the Company. Tecogen is a leading manufacturer of natural gas, engine-driven commercial and industrial cooling and cogeneration systems suitable for a variety of applications, including hospitals, nursing homes and schools. A CHP system simultaneously produces two types of energy - heat and electricity - from a single fuel source, generally natural gas. The two key components of a CHP system are an internal combustion reciprocating engine and an electric generator. The clean natural gas fired engine spins a generator to produce electricity. The natural byproduct of the working engine is heat. The heat is captured and used to supply space heating, domestic hot water heating, laundry hot water, or heating for swimming pools and spas. While Tecogen is our

2

AMERICAN DG ENERGY INC.


principal supplier of CHP equipment, we believe there are enough alternative vendors of CHP to satisfy the Company's needs.
In July 2010, the Company established EuroSite Power Inc., or EuroSite Power, a subsidiary formed to introduce the Company's On-Site Utility solution into the European market. As of December 31, 2014 the Company owned a 50.1% interest in EuroSite Power and had consolidated EuroSite Power into its financial statements in accordance with generally accepted accounting principles, or GAAP.

As power sources that use alternative energy technologies mature to the point when they are both reliable and economical, we will consider employing them to supply energy for our customers. We regularly assess the technical, economic, reliability and emissions issues associated with systems that use solar, micro-turbine or fuel cell technologies to generate power.
The Company and its Affiliates

EuroSite Power, Tecogen and Ilios Inc., or Ilios, are affiliated companies by virtue of common ownership. The common stockholders include:

John N. Hatsopoulos, the Co-Chief Executive Officer and a director of the Company who holds 19.4% of its common stock is also: (a) the Chairman of EuroSite Power and holds 4.3% of their common stock; (b) the Chief Executive Officer and a director of Tecogen and holds 23.4% of their common stock and (c) a director of Ilios and holds 7.2% of their common stock.

Dr. George N. Hatsopoulos, who is John N. Hatsopoulos' brother, holds 13.0% of the Company's common stock and also: (a) holds of 22.4% of Tecogen's common stock; (b) holds 3.1% of Ilios's common stock and (c) holds 0.7% of EuroSite Power's common stock.

Background and Market
The delivery of energy services to commercial and residential customers in the U.S., we believe, has evolved over many decades into an inefficient and increasingly unreliable structure. Power for lighting, air conditioning, refrigeration, communications and computing demands comes almost exclusively from centralized power plants serving users through a complex grid of transmission and distribution lines and substations. Even with continuous improvements in central station generation and transmission technologies, today's power industry is only about 33% efficient, meaning that it discharges to the environment roughly twice as much heat as the amount of electrical energy delivered to end-users (see Energy Information Administration, Voluntary Reporting of Greenhouse Gases, 2004, Section 2, Reducing Emissions from Electric Power, Efficiency Projects: Definitions and Terminology, page 20, available at http://www.eia.gov/oiaf/1605/archive/vr04data/pdf/0608(04).pdf. This website address and any other website addresses included in this Annual Report on Form 10-K are included as textual references only and the information in such websites is not incorporated by reference into this Annual Report on Form 10-K). Since coal accounts for more than half of all electric power generation, these inefficiencies are a major contributor to rising atmospheric CO2 emissions. As countermeasures are sought to limit global warming, environmental pressures against coal will favor the deployment of alternative energy technologies.
On-site boilers and furnaces burning either natural gas or petroleum distillate fuels produce most thermal energy for space heating and hot water services. This separation of thermal and electrical energy supply services has persisted despite a general recognition that CHP can be significantly more energy efficient than central generation of electricity by itself. Except in large-scale industrial applications (e.g., paper and chemical manufacturing), cogeneration has not yet attained general acceptance. This is due, in part, to the long-established monopoly-like structure of the regulated utility industry. Also, the technologies previously available for small on-site cogeneration systems were incapable of delivering the reliability, cost and environmental performance necessary to displace or even substantially modify the established power industry structure.
Because of these factors, electricity reserve margins have declined, and the reliability of service has begun to deteriorate, particularly in regions of high economic growth. Widespread acceptance of computing and communications technologies by consumers and commercial users has further increased the demand for electricity, while also creating new requirements for very high power quality and reliability. At the same time, technological advances in emission control, microprocessors and internet technologies have sharply altered the competitive balance between centralized generation and DG. These fundamental shifts in economics and requirements are key to the emerging opportunity for DG equipment and services.

AMERICAN DG ENERGY INC.


The Role of DG
DG, or cogeneration, is the production of two sources or two types of energy (electricity or cooling and heat) from a single energy source (natural gas). We use technology that utilizes a low-cost, mass-produced, internal combustion engine from General Motors, used primarily in light trucks and sport utility vehicles that is modified to run on natural gas. The engine spins either a standard generator to produce electricity, or a conventional compressor to produce cooling. For heating, since the working engine generates heat, we capture the byproduct heat with a heat exchanger and utilize the heat for facility applications in the form of space heating and hot water for buildings or industrial facilities. This process is very similar to an automobile, where the engine provides the motion to the automobile and the byproduct heat is used to keep the passengers warm during the winter months. For refrigeration or cooling, standard available equipment uses an electric motor to spin a conventional compressor to make cooling. We replace the electric motor with the same modified engine that runs on natural gas to spin the compressor to run a refrigeration cycle and produce cooling.
DG refers to the application of small-scale energy production systems, including electricity generators, at locations in close proximity to the end-use loads that they serve. Integrated energy systems, operating at user sites but interconnected to existing electric distribution networks, can reduce demand on the nation's utility grid, increase energy efficiency, avoid the waste inherent in long distance wire and cable transmission of electricity, reduce air pollution and greenhouse gas emissions, and protect against power outages, while, in most cases, significantly lowering utility costs for power users and building operators.
Until recently, many DG technologies have not been a feasible alternative to traditional energy sources because of economic, technological and regulatory considerations. Even now, many “alternative energy” technologies (such as solar, wind, fuel cells and micro-turbines) have not been sufficiently developed or proven to economically meet the demands of commercial users or the ability to be connected to the existing utility grid.
We supply cogeneration systems that are capable of meeting the demands of commercial users and that can be connected to the existing utility grid. Specific advantages of the Company's on-site DG of multiple energy services, compared with traditional centralized generation and distribution of electricity alone, include the following:
Greatly increased overall energy efficiency (up to 90% versus less than 33% for the existing power grid - see Environmental and Energy Study Institute (EESI), Energy Generation and Distribution Efficiency, available at http://www.eesi.org/generation_distribution. This website address and any other website addresses included in this Annual Report on Form 10-K are included as textual references only and the information in such websites is not incorporated by reference into this Annual Report on Form 10-K).
Rapid adaptation to changing demand requirements (e.g., weeks, not years, to add new generating capacity where and when it is needed).
Ability to by-pass transmission line and substation bottlenecks in congested service areas.
Avoidance of site and right-of-way issues affecting large-scale power generation and distribution projects.
Clean operation, in the case of natural gas fired reciprocating engines using microprocessor combustion controls and low-cost exhaust catalyst technology developed for automobiles.
Rapid economic paybacks for equipment investments, as fast as four to six years when compared to existing utility costs and technologies.
Decreased sensitivity to fuel prices due to high overall efficiencies achieved with cogeneration of electricity and thermal energy, including the use of waste heat to operate absorption type air conditioning systems (displacing electric-powered cooling capacity at times of peak summer demand).
Reduced vulnerability of multiple de-centralized small-scale generating units compared to the risk of major outages from natural disasters or terrorist attacks against large central-station power plants and long distance transmission lines.
Ability to remotely monitor, control and dispatch energy services on a real-time basis using advanced switchgear, software, microprocessor and internet modalities. Through our on-site energy products and services, energy users are able to optimize, in real time, the mix of centralized and distributed electricity-generating resources.

Also, DG systems possess significant positive environmental impact. The EPA has created a Combined Heat and Power Partnership to promote the benefits of DG systems. The Company is a member of this Partnership. The following statement is found on the EPA web site.
"Combined heat and power systems offer considerable environmental benefits when compared with purchased electricity and onsite-generated heat. By capturing and utilizing heat that would otherwise be wasted from the production of electricity, CHP systems require less fuel than equivalent separate heat and power systems to produce the same amount of

4

energy. Because less fuel is combusted, greenhouse gas emissions, such as carbon dioxide (CO2), as well as criteria air pollutants like nitrogen oxides (NOx) and sulfur dioxide (SO2), are reduced." (See: http://epa.gov/chp/basic/environmental.html).
Business Model
We are a DG onsite energy company that sells energy in the form of electricity, heat, hot water and air conditioning under long-term contracts with commercial, institutional and light industrial customers with a typical term of 10 to 15 years. We install our systems at no cost to our customers and retain ownership of the system. Because our systems operate at over 90% efficiency (versus less than 33% for the existing power grid -see Environmental and Energy Study Institute (EESI), Energy Generation and Distribution Efficiency, available at http://www.eesi.org/generation_distribution. This website address and any other website addresses included in this Annual Report on Form 10-K are included as textual references only and the information in such websites is not incorporated by reference into this Annual Report on Form 10-K), we are able to sell the energy produced by these systems to our customers at prices below their existing cost of electricity (or air conditioning), heat and hot water. Our cogeneration systems consist of natural gas-powered internal combustion engines that drive an electrical generator to produce electricity and that capture the engine heat to produce space heating and hot water. Our energy systems also can be configured to drive a compressor that produces air conditioning and that also captures the engine heat. As of December 31, 2014, we had 123 energy systems operational.
To date, each of our installations runs in conjunction with the electric utility grid and requires standard interconnection approval from the local utility. Our customers use both our energy system and the electric utility grid for their electricity requirements. We typically supply the first 20% to 60% of the building's electricity requirements while the remaining electricity is supplied by the electric utility grid. Our customers are contractually bound to use the energy we supply.
To date, the price that we have charged our customers is set in our customer contracts at a discount to the price of the building's local electric utility. For the 20% to 60% portion of the customer's electricity that we supply, the customer realizes immediate savings on his/her electric bill. In addition to electricity, we sell our customers the heat and hot water at the same price they were previously paying or at a discount equivalent to their discount from us on electricity. Our air conditioning systems are also priced at a discount so that the customer realizes overall cost savings from the installation.
Since we own and operate the energy systems and since our customers have no investment in the units, our customers benefit from no capital requirements and no operating responsibilities. We manage the energy systems so our customers require no staff, and have no energy system responsibilities. They are bound, however, to pay for the energy supplied by the energy systems over the term of the agreement.

For customers seeking an alternative to the outright purchase of CHP equipment, we will install, maintain, finance, own and operate complete on-site CHP systems that supply, on a long-term, contractual basis, electricity and other energy services. We sell the energy to customers at a guaranteed discount rate to the rates charged by conventional utility suppliers. Customers benefit from our On-Site Utility in a number of ways:

AMERICAN DG ENERGY INC.



Guaranteed lower price for energy
Only pay for the energy they use
No capital costs for equipment, engineering and installation
No equipment operating costs for fuel and maintenance
Immediate cash flow improvement
Significant green impact by the reduction of carbon produced
No staffing, operations and equipment responsibility
Customers are billed monthly and benefit from a reduction in their current energy bills without the capital costs and risks associated with owning and operating a cogeneration or chiller system. Also, by outsourcing the management and financing of on-site energy facilities to us, they can reap the economic advantages of DG without the need for retaining specialized in-house staff with skills unrelated to their core business. We also agree to obtain any necessary permits or regulatory approvals at our sole expense. Our agreements are generally for a term of 15 years, renewable for two additional five years terms upon the mutual agreement of the parties.

In regions where high electricity rates prevail, such as the Northeast, monthly payments for CHP energy services can yield attractive paybacks (e.g. in some cases as quickly as 3-5 years) on our investments in On-Site Utility projects. The price of natural gas has a minor effect on the financial returns obtained from our energy service contracts because we believe the value of hot water and other thermal services produced from the recovered heat generated by the internal combustion engine in our on-site DG system will generally increase or decrease faster relative to higher or lower fuel costs. This recovered energy, which comprises up to 60% of the total heating value of fuel supplied to our CHP equipment, displaces some fuel use, but requires less than would otherwise be burned in a conventional boiler. Each of our customer sites becomes a profit center. The example below presents the energy supplied by two 75 kW cogeneration units and the economics of a typical energy service contract where we supply 80% of the site's heat and hot water and 45% of the site's electricity. Our customers range from hotels to nursing homes and apartment buildings and they usually require two energy systems or more. The savings calculations in the example are based on many variables, such as the customer's base electricity charge per kWh, the kW used at the site, the operating time of the equipment, the customer's base gas price per 1 million BTU, or British Thermal Units, the net heat recovery of our equipment, the efficiency of the customer's boiler, the electric demand savings rate and the discount to the customer, which may range from 0% to 10%. The economics of the Company's typical energy service contract assumes that the customer's base electric rate per kWh and gas price per 1 million BTU is greater than or equal to $0.14 per kWh and 1 million BTU at $12.00, respectively. The example also reflects a 2% of expected annual increase in energy costs that should occur over a 15-year period:

The example reflects an American DG Energy investment of $345,000 with a payback in 4 years or a 25% internal rate of return.
Energy Producing Products
We typically offer cogeneration units sized to produce 75 kW to 100 kW of electricity, water chillers sized to produce 200 to 400 tons of cooling and ultra-high-efficiency heating products, such as with the high efficiency water heater.
For cogeneration, we prefer a modular design approach to allow us to group multiple units together to serve customers with considerably larger power requirements. Often, cogeneration units are conveniently dispersed within a large operation, such as a hospital or campus, serving multiple process heating systems that would otherwise be impractical to serve from a single large machine. The equipment we select often yield overall energy efficiencies in excess of 80% (from our equipment supplier's specifications). We also purchase energy equipment that incorporates mechanical work to extract heat from the environment, like high-efficiency water heaters, in order to supplement the chemical energy available in the fuel. The result is a significant boost in efficiency and reduced carbon emissions relative to conventional heating systems.
Many other DG technologies are challenged by technical, economic and reliability issues associated with systems that generate power using solar, micro-turbine or fuel cell technologies, which have not yet proven to be economical for

6

AMERICAN DG ENERGY INC.


typical customer needs. When alternative energy technologies mature to the point that they are both reliable and economical, we will employ them for the best-fit applications.
Service and Installation

Where appropriate, we utilize the best local service infrastructure for the equipment we deploy. We require long-term maintenance contracts and ongoing parts sales. Our centralized remote monitoring capability allows us to keep track of our equipment in the field. Our installations are performed by local contractors with experience in energy cogeneration systems.
    
For the customers that want to own the CHP system themselves, we offer our “turn-key” option whereby we provide equipment, systems engineering, installation, interconnect approvals, on-site labor and startup services needed to bring the complete CHP system on-line. For some customers, we are also paid a fee to operate the systems and may receive a portion of the savings generated from the equipment.

Other Funding and Revenue Opportunities
    
The Company is able to participate in the demand response market and receive payments due to the availability of our energy systems. Demand response programs provide payments for either the reduction of electricity usage or the increase in electricity production during periods of peak usage throughout a utility territory. We have also received grants and incentives from state organizations and natural gas companies for our installed energy systems.

Sales and Marketing

Our On-Site Utility services are sold directly to end-users by our in-house marketing team and by established sales agents and representatives. We offer standardized packages of energy, equipment and services suited to the needs of property owners and operators in healthcare, hospitality, large residential, athletic facilities and certain industrial sites. This includes national accounts and other customer groups having a common set of energy requirements at multiple locations.

We focus our marketing efforts on senior management and technical personnel, who are best situated to recognize the gain in cash flow, the increase in net income and the preservation of capital we offer. As such, our energy sales are focused on reaching these decision makers. Additionally, we have benefited with increased sales and maintenance support through our consolidated 51.0% joint venture with AES-NJ Cogen Co. and American DG NY LLC, or ADGNY. AES-NJ Cogen Co. is an established developer of small cogeneration systems.

The Company is continually expanding its sales efforts by developing joint marketing initiatives with key suppliers to our target industries.

DG is enjoying growing support among state utility regulators seeking to increase the reliability of electricity supply with cost effective and environmentally responsible demand-side resources. New York, New Jersey, Connecticut and Massachusetts are among the states that encourage DG through inter-connecting standards, incentives and/or supply planning. Unlike large central station power plants, DG investments can be made in small increments and with lead-times as short as just a few months.
    
Competition

We compete with established utilities that provide electricity, wholesale electricity and gas utility distributors, companies that provide services similar to ours, and other forms of alternative energy. DG is beginning to gain acceptance in regions where energy customers are dissatisfied with the cost and reliability of traditional electricity service. These end-users, together with growing support from state legislatures and regulators, are creating a favorable climate for the growth of DG that is overcoming the objections of established utility providers. In our target markets, we compete with large utility companies such as Con Edison, Inc. and Long Island Power Authority in New York, Public Service Electric and Gas Company (PSE&G) in New Jersey, and Eversource and National Grid USA Service Company, Inc. in Massachusetts. Those companies are much larger than us in terms of revenues, assets and resources. We aim to compete with large utility companies by selling electricity to the same commercial building customers. We sell directly to each building customer, but typically only supply 20%-60% of the electricity needs of the building. The remaining portion is supplied by the electric utility. We aim to compete with electric utilities by selling electricity at a lower price. However, there is no assurance we will be able to provide electricity at a lower price.

AMERICAN DG ENERGY INC.


In the United Kingdom, we primarily compete with Cogenco Limited, a subsidiary of Dalkia PLC and ENER-G plc, both alternative energy companies with customers in the 50-5,000 kW range, and Jenbacher, a subsidiary of General Electric Company via their UK distributor Clarke Energy Ltd. Other companies in the same market are Pure World Energy and Vital Energi. Competing equipment manufactures also selling CHP solutions include SAV Systems, Worcester Bosch, Veissman and Baxi-SenerTec UK. Elsewhere in Europe competition includes CogenGreen S.A., Capstone Turbine Corporation, Cummins Power Generation Inc, EC Power Systems, Baxi-SenerTec UK, MicroPower Europe, Guascor Power, Icogen SA and Pasch y Cia SA.

Engine manufacturers sell DG units that range in size from a few kWs to many MWs in size. Those manufacturers are predominantly greater than 1 MW and include Caterpillar Inc., Cummins Power Generation Inc., and Waukesha, a subsidiary of General Electric Company. In many cases, we view these companies as potential suppliers of equipment and not as competitors. For example, we have installed a Waukesha unit at a customer site.

The alternative energy market is emerging rapidly. Many companies are developing alternative and renewable energy sources including solar power, wind power, fuel cells and micro-turbines. Some of the companies in this sector include General Electric Company, BP p.l.c, Royal Dutch Shell and SunEdison, a division of MEMC Electronic Materials, Inc.; Plug Power, Inc. and FuelCell Energy, Inc. (in the fuel cell space); and Capstone Turbine Corporation, Ingersoll Rand PLC and Elliott Turbomachinery, a division of the Elliott Group, Inc. (in the micro-turbine space). The effect of these developing technologies on our business is difficult to predict; however, when their technologies become more viable for our target markets, we may be able to adopt their technologies into our business model.

There are a number of energy service companies that offer related services. These companies include Siemens AG, Honeywell International Inc. and Johnson Controls Inc. In general, these companies seek large, diverse projects for electric demand reduction for campuses that include building lighting and controls, and electricity (on rare occasions) or cooling. Because of their overhead structures, these companies often solicit large projects rather than individual properties. Since we focus on smaller projects for energy supply, we believe we are suited to work in tandem with these companies when the opportunity arises.

There are also a few local emerging cogeneration developers and contractors that are attempting to offer services similar to ours. To be successful, they would need to have the proper experience in equipment and technology, installation contracting, equipment maintenance and operation, economic site evaluation, project financing and energy sales plus capability of covering a broad region.
Material Contracts
American DG Energy signed a Facilities and Support Services Agreement with Tecogen on January 1, 2006, as amended. The term of the agreement is 1 year. Certain portions of the agreement, including office space allocation, are renewed or amended annually upon mutual written agreement.

On August 8, 2014, the Company entered into a new Facilities, Support Services and Business Agreement with Tecogen. This agreement between the Company and Tecogen states that in exchange for consideration Tecogen will provide the Company with, among other things; (1) certain office space; (2) certain business support services; (3) certain rights to purchase Cogeneration products directly from Tecogen at a discounted price; (4) certain rights to purchase Tecogen services at a discounted price; (5) certain rights that allow the Company to purchase Tecogen products from Tecogen’s sales representatives; and (6) the right to certain royalty fees. The Agreement was effective July 1, 2014 and shall expire on July 1, 2015. Under this agreement the Company leases from Tecogen approximately 3,282 square feet. The amount that the Company pays Tecogen for the space and services that Tecogen provides under the agreement is approximately $6,495 per month.

We have granted Tecogen sales representation rights to our On-Site Utility energy service in California.
In October 2009, as amended on November 12, 2013, the Company entered into a five-year exclusive distribution agreement with Ilios, a subsidiary of Tecogen that was formed in April 2009 to develop and distribute a line of ultra-high-efficiency heating products, such as a high efficiency water heater, that provide twice the efficiency of conventional boilers, based on management estimates, for commercial and industrial applications utilizing advanced thermodynamic principles. Under terms of the agreement, the Company has exclusive rights to incorporate Ilios' products in its energy systems throughout the European Union and New England. The Company also has non-exclusive rights to distribute Ilios' products into the remaining parts of the United States and the world in cases where the Company retains ownership of the equipment for its On-Site Utility business. The agreement allows Ilios to appoint sales representatives in the European Union (EU) in addition to the Company.

Government Regulation
We are subject to extensive government regulation. We are required to file for local construction permits (electrical, mechanical and the like) and utility interconnects, and we must make various local and state filings related to environmental emissions. The U.S. government has been developing and refining various funding opportunities related to its economic recovery or stimulus initiatives. The Company believes that its CHP systems would fit very well with any of these programs. Other than funding opportunities related to the economic recovery or stimulus initiatives, there does not appear to be any new government regulations that will affect the Company.

Compliance with Environmental Laws

We are not required to comply with any environmental laws that are particular to our business, either in the United States or Europe. However, it is our policy to be environmentally conscientious in every aspect of our operations.

Employees

As of December 31, 2014, the Company employed twenty-five active full-time employees and one part-time employee. We believe that our relationship with our employees is satisfactory. None of our employees are represented by a collective bargaining agreement.

Item 1A. Risk Factors.

Our business faces many risks. The risks described below may not be the only risks we face. Additional risks that we do not yet know of, or that we currently think are immaterial, may also impair our business operations or financial results. If any of the events or circumstances described in the following risks occurs, our business, financial condition or results of operations could suffer and the trading price of our common stock could decline. Investors and prospective investors should consider the following risks and the information contained under the heading ''Warning Concerning Forward-Looking Statements'' before deciding whether to invest in our securities.
We have incurred losses, and these losses may continue.

We have incurred losses in each of our fiscal years since inception. There is no assurance that profitability will be achieved in the near term, if at all in the future.

Because unfavorable utility regulations make the installation of our systems more difficult or less economical, any slowdown in the utility deregulation process would be an impediment to the growth of our business.

In the past, many electric utility companies have raised opposition to DG, a critical element of our On-Site Utility business. Such resistance has generally taken the form of unrealistic standards for interconnection, and the use of targeted rate structures as disincentives to combined generation of on-site power and heating or cooling services. A DG company's ability to obtain reliable and affordable back-up power through interconnection with the grid is essential to our business model. Utility policies and regulations in most states are often not prepared to accommodate widespread on-site generation. These barriers erected by electric utility companies and unfavorable regulations, where applicable, make more difficult or uneconomic our ability to connect to the electric grid at customer sites and are an impediment to the growth of our business. Development of our business could be adversely affected by any slowdown or reversal in the utility deregulation process or by difficulties in negotiating backup power supply agreements with electric providers in the areas where we intend to do business.

Our onsite utility concept is largely unproven in the United States and United Kingdom and may not be accepted by a sufficient number of customers.
    
The sale of cogeneration and cooling equipment has been successfully carried out for more than a decade. However, our On-Site Utility concept (i.e., the sale of on-site energy services, rather than equipment) is still in an early stage of implementation. Unresolved issues include the pricing of energy services and the structuring of contracts to provide cost savings to customers and optimum financial returns to us. There is no assurance that we will be successful in developing a profitable On-Site Utility business model, and failure to do so would have a material adverse effect on our business and financial performance.

AMERICAN DG ENERGY INC.


The economic viability of our projects depends on the price spread between fuel and electricity, and the variability of the prices of these components creates a risk that our projects will be uneconomic.

The economic viability of DG projects is dependent upon the price spread between fuel costs and electricity prices. Volatility in one component of the spread, the cost of natural gas and other fuels (e.g., propane or distillate oil) can be managed to a greater or lesser extent by means of futures contracts. However, the regional rates charged for both base load and peak electricity services may decline periodically due to excess capacity arising from over-building of utility power plants or recessions in economic activity. Any sustained weakness in electricity prices could significantly limit the market for our cogeneration, cooling equipment and On-Site Utility energy services.

We may fail to make sales to certain prospective customers because of resistance from facilities management personnel to the outsourcing of their service function.

Any outsourcing of non-core activities by institutional or commercial entities will generally lead to reductions in permanent on-site staff employment. As a result, our proposals to implement On-Site Utility contracts are likely to encounter strong initial resistance from the facilities managers whose jobs will be threatened by energy outsourcing. The growth of our business will depend upon our ability to overcome such barriers among prospective customers.

Future government regulations, such as increased emissions standards, safety standards and taxes, may adversely impact the economics of our business.

The operation of DG equipment at our customers' sites may be subject to future changes in federal, state and local laws and regulations (e.g., emissions, safety, taxes, etc.). Any such new or substantially altered rules and standards may adversely affect our revenues, profits and general financial condition.

If we cannot expand our network of skilled technical support personnel, we will be unable to grow our business.

Each additional customer site for our services requires the initial installation and subsequent maintenance and service of equipment to be provided by a team of technicians skilled in a broad range of technologies, including combustion, instrumentation, heat transfer, information processing, microprocessor controls, fluid systems and other elements of DG. If we are unable to recruit, train, motivate, sub-contract, and retain such personnel in each of the regional markets where our business operates we will be unable to grow our business in those markets.

The Company operates in highly competitive markets and may be unable to successfully compete against competitors having significantly greater resources and experience.

Our business may be limited by competition from energy services companies arising from the breakup of conventional regulated electric utilities. Such competitors, both in the equipment and energy services sectors, are likely to have far greater financial and other resources than us, and could possess specialized market knowledge with existing channels of access to prospective customer locations. We may be unable to successfully compete against those competitors.

Our ability to access capital for the repayment of debts and for future growth is limited as the financial markets can be unpredictable.
 
Our ability to access capital could be impacted by various factors including general market conditions or a slowdown in the economy, interest rates, the perception of our potential future earnings and cash distributions, any unwillingness on the part of lenders to make loans to us and any deterioration in the financial position of lenders that might make them unable to meet their obligations to us.

Future technology changes may render obsolete various elements of equipment comprising our On-Site Utility installations.

We must select equipment for our DG projects so as to achieve attractive operating efficiencies, while avoiding excessive downtimes from the failure of unproven technologies. If we are unable to achieve a proper balance between the cost, efficiency and reliability of equipment selected for our projects, our growth and profitability will be adversely impacted.

Operating diverse on-site utility sites across many different locations presents significant maintenance challenges.

We operate 123 systems at various locations which require considerable monitoring and maintenance on a twenty-four hour basis. Managing multiple sites simultaneous creates challenges of engineering resource and spare part availability.

We will need to raise additional capital for our business, which will dilute existing stockholders.

Additional financings will be required to implement our overall business plan. We will need additional capital. Equity financings will dilute the percentage ownership of our existing stockholders. Our ability to raise an adequate amount of capital and the terms of any capital that we are able to raise will be dependent upon our progress in implementing demonstration projects and related marketing service development activities. If we do not make adequate progress, we may be unable to raise adequate funds, which will limit our ability to expand our business. If the terms of any equity financings are unfavorable, the dilutive impact on our stockholders might be severe.

We may make acquisitions that could harm our financial performance.

In order to expedite development of our corporate infrastructure, particularly with regard to equipment installation and service functions, we anticipate the future acquisition of complementary businesses. Risks associated with such acquisitions include the disruption of our existing operations, loss of key personnel in the acquired companies, dilution through the issuance of additional securities, assumptions of existing liabilities and commitment to further operating expenses. If any or all of these problems actually occur, acquisitions could negatively impact our financial performance and future stock value.

We are controlled by a small group of majority stockholders, and our minority stockholders could be unable to effect changes in our governance structure or implement actions that require stockholder approval, such as a sale of the Company.

George N. Hatsopoulos and John N. Hatsopoulos, who are brothers, beneficially own a large portion of our outstanding shares of common stock. These stockholders, with a small group of other major stockholders, have the ability to control various corporate decisions, including our direction and policies, the election of directors, the content of our charter and bylaws and the outcome of any other matter requiring stockholder approval, including a merger, consolidation and sale of substantially all of our assets or other change of control transaction. The concurrence of our minority stockholders will not be required for any of these decisions.

We may be exposed to substantial liability claims if we fail to fulfill our obligations to our customers.

We enter into contracts with large commercial and not-for-profit customers under which we will assume responsibility for meeting a portion of the customers' building energy demand and equipment installation. We may be exposed to substantial liability claims if we fail to fulfill our obligations to customers. There can be no assurance that we will not be vulnerable to claims by customers and by third parties that are beyond any contractual protections that we are able to negotiate. We may be unable to obtain liability and other insurance on terms and at prices that are commercially acceptable to us. As a result, liability claims could cause us significant financial harm.

Investment in our common stock is subject to price fluctuations which have been significant for emerging growth companies like us.

Historically, valuations of emerging growth companies have been highly volatile. The securities of many of these companies have experienced significant price and trading volume fluctuations, unrelated to the operating performance or the prospects of such companies. If the conditions in the equity markets further deteriorate, we may be unable to finance our additional funding needs in the private or the public markets. There can be no assurance that any future offering will be

11

AMERICAN DG ENERGY INC.


consummated or, if consummated, will be at a share price equal or superior to the price paid by our investors even if we meet our technological and marketing goals.
    
Future sales of common stock by our existing stockholders may cause our stock price to fall.

The market price of our common stock could decline as a result of sales by our existing stockholders of shares of common stock in the market or the perception that these sales could occur. These sales might also make it more difficult for us to sell equity securities at a time and price that we deem appropriate and thus inhibit our ability to raise additional capital when it is needed.

Because we do not intend to pay cash dividends, our stockholders will receive no current income from holding our stock.

We have paid no cash dividends on our capital stock to date and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. We currently expect to retain earnings for use in the operation and expansion of our business, and therefore do not anticipate paying any cash dividends in the foreseeable future. In addition, the terms of any future debt or credit facility may preclude us from paying any cash dividends. As a result, capital appreciation, if any, of our common stock could be the sole source of gain for our stockholders for the foreseeable future.

Our business is affected by general economic conditions and related uncertainties affecting markets in which we operate. The current economic conditions could adversely impact our business in 2015 and beyond.

The current economic conditions could adversely impact our business in 2015 and beyond, resulting in reduced demand for our products, increased rate of order cancellations or delays, increased risk of excess and obsolete inventories, increased pressure on the prices for our products and services; and greater difficulty in collecting accounts receivable.

There are material weaknesses in our disclosure controls and procedures and our internal control over financial reporting, which could harm our operating results or cause us to fail to meet our reporting obligations.

As of the end of the period covered by this Annual Report on Form 10-K, our principal executive officer and principal accounting officer have performed an evaluation of controls and procedures and concluded that our controls were not effective to provide reasonable assurance that information required to be disclosed by our Company in reports that we file under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported as and when required. Management conducted an evaluation of our internal control over financial reporting and based on this evaluation, management concluded that the Company's internal control over financial reporting was not effective as of the end of the period covered by this report. The Company currently has material weaknesses in financial reporting relating to the lack of a sufficient number of controls over manual processes of revenue recognition. This constitutes a material weakness in financial reporting. Any failure to implement effective internal controls could harm our operating results or cause us to fail to meet our reporting obligations. Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock, and might require us to incur additional costs to improve our internal control system.

Trading of our common stock is restricted by the Securities and Exchange Commission's, or the SEC's, “penny stock” regulations which may limit a stockholder's ability to buy and sell our stock.

The SEC has adopted regulations which generally define “penny stock” to be any equity security that has a market price less than $5.00 per share or an exercise price of less than $5.00 per share, subject to certain exceptions. Our securities may be covered by the penny stock rules, which impose additional sales practice requirements on broker-dealers who sell to persons other than established customers and accredited investors. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC that provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and other quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction and monthly account statement showing the market value of each penny stock held in the customer's account. The bid and offer quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer's confirmation. In addition, the penny stock rules require that prior to a transaction in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to the transaction. These disclosure and suitability requirements may have the effect of reducing the level of trading activity in

12

AMERICAN DG ENERGY INC.


the secondary market for a stock that is subject to these penny stock rules. Consequently, these penny stock rules may affect the ability of broker-dealers to trade our securities. We believe that the penny stock rules discourage investor interest in and limit the marketability of our capital stock. Trading of our capital stock may be restricted by the SEC's “penny stock” regulations which may limit a stockholder's ability to buy and sell our stock.

None.

Item 2.    Properties.
Our headquarters are located in Waltham, Massachusetts and consist of 3,282 square feet of office and storage space that are shared with EuroSite Power and are sub-leased from Tecogen. We believe that our facilities are appropriate and adequate for our current needs.

Item 3.    Legal Proceedings.

We are not currently a party to any material litigation, and we are not aware of any pending or threatened litigation against us that could have a material adverse effect on our business, operating results or financial condition.

Holders
  
As of March 30, 2015, there were approximately 49 holders of our common stock.
 
Special Stock Dividend
 
On July 2, 2013, the Company declared a special dividend of one share of EuroSite Power common stock for every ten shares of the Company's common stock. The special dividend was paid on August 15, 2013, to stockholders of record as of the close of business on July 25, 2013 and in connection with this transaction the Company issued to its stockholders an aggregate of 4,880,679 shares of EuroSite Power common stock that it owns. The EuroSite Power shares issued pursuant to the special dividend are not restricted securities in the hands of shareholders who are not affiliates of the Company or Eurosite Power. Affiliates may sell the securities only after a 6 month holding period pursuant to the provisions of the SEC's Rule 144.

On August 15, 2013, in connection with the special dividend, the Company modified the conversion price of the 6%, $19,400,000 convertible debentures issued on May 23, 2011  and November 30, 2011 from $2.20 to $2.11 per share.

We have never declared or paid any cash dividends on shares of our common stock. We currently intend to retain earnings, if any, to fund the development and growth of our business and do not anticipate paying cash dividends in the foreseeable future. Our payment of any future dividends will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, cash needs and growth plans.

Our management has conducted an assessment of the risks associated with our compensation policies and practices. This process included a review of our compensation programs, a discussion of the types of practices that could be reasonably likely to create material risks, and an analysis of the potential effects on the company on related risks as a whole. Although we reviewed all of our compensation programs, we paid particular attention to programs involving incentive-based payouts and programs that involve our executive officers. During the course of our assessment, we consulted with the Compensation Committee of our Board of Directors. We believe that our compensation programs are designed to create appropriate incentives without encouraging excessive risk taking by our employees. In this regard, our compensation structure contains various features intended to mitigate risk. For example:
 
A portion of the compensation package for our sales-based employees consists of commissions for units sold and installed, which package is designed to link an appropriate portion of compensation to long-term performance, while providing a balanced compensation model overall.

The Compensation Committee oversees our compensation policies and practices and is responsible for reviewing and approving executive compensation, annual incentive compensation plans applicable to sales employees and other compensation plans.

Our Compensation Committee, in its evaluation, determined that the company does not employ any compensation plans or practices that create incentives for employees to deliver short-term profits at the expense of generating systematic risks for the Company. Based on this and the assessment described above, we have concluded that the risks associated with our compensation policies and practices are not reasonably likely to have a material adverse effect on the Company.

The grant of such options was exempt from registration under Rule 701 under the Securities Act.

Convertible Debentures

On May 25, 2014, the total interest due to the debenture holders was $582,000 and the Company issued to the debenture holders 260,154 shares of common stock at $2.24 per share which was the average price of the Company's common stock during the month of April. In connection with this transaction, the Company recorded an additional charge of $42,368 of non-cash interest expense, which was the difference between the average stock price and the fair market value on May 25, 2014.

On October 3, 2014, the Company consummated a series of transactions whereby, under an agreement with the holders of the Company’s existing 6% Senior Unsecured Convertible Debentures Due 2018, or the convertible debentures, it paid the interest due under the convertible debentures through the next semiannual payment date of November 25, 2014 by delivering to the holders of the convertible debentures 1,164,000shares of common stock of its subsidiary EuroSite Power, which were owned by the Company and which had a market value of $582,000.The Company also delivered 8,245,000 additional shares of EuroSite Power it owned with an aggregate market value of $4,122,500 to the holders of the convertible debentures for prepayment of all interest which would become due under the convertible debentures through the maturity date of May 25, 2018. In connection with these transactions, the Company also delivered to the holders of the convertible debentures three year warrants with an exercise price per share of $0.60 to purchase an additional 1,164,000 shares of EuroSite Power from the Company with an aggregate market value of $84,911.

Following the payment of all current and future interest under the convertible debentures, the Company exchanged the convertible debentures which bore interest at an annual rate of 6% for non-interest bearing convertible debentures with all other terms including the principal amount, maturity date, and conversion terms and privileges remaining unchanged. The face amount of the convertible debentures at December 31, 2014 was $19,400,000. See Financial Statements, Note 4 "Convertible debentures" for the details of all convertible debenture transactions.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. You should review “Item 1A. Risk Factors” beginning on page 10 of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview
 
We primarily derive sales from selling energy in the form of electricity, heat, hot water and cooling to our customers under long-term energy sales agreements (with a typical term of 10 to 15 years). The energy systems are owned by us and are installed in our customers’ buildings. Each month we obtain readings from our energy meters to determine the amount of energy produced for each customer. We multiply these readings by the appropriate published price of energy (electricity, natural gas or oil) from our customers’ local energy utility, to derive the value of our monthly energy sale, less the applicable negotiated discount. Our revenues per customer on a monthly basis vary based on the amount of energy produced by our energy systems and the published price of energy (electricity, natural gas or oil) from our customers’ local energy utility that month. Our revenues commence as new energy systems become operational. As of December 31, 2014, we had 123 energy systems operational.
  
In some cases the customer may choose to own the energy system rather than have it owned by American DG Energy. In this case, we account for revenue and costs using the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting, revenues are recognized by applying percentages of completion to the total estimated revenues for the respective contracts. Costs are recognized as incurred. The percentages of completion are determined by relating the actual cost of work performed to date to the current estimated total cost at completion of the respective contracts. When the estimate on a contract indicates a loss, the Company’s policy is to record the entire expected loss, regardless of the percentage of completion. The excess of contract costs and profit recognized to date on the percentage-of-completion accounting method in excess of billings is recorded as unbilled revenue. Billings in excess of related costs and estimated earnings is recorded as deferred revenue. Customers may buy out their long-term obligation under energy contracts and purchase the underlying equipment from the Company. Any resulting gain on these transactions is recognized over the payment period in the accompanying consolidated statements of operations. Revenues from operation and maintenance services, including shared savings are recorded when provided and verified.

We have experienced total net losses since inception of approximately $35.2 million. For the foreseeable future, we expect to experience continuing operating losses and negative cash flows from operations as our management executes our current business plan. The cash and cash equivalents available at December 31, 2014 will, we believe, provide sufficient working capital to meet our anticipated expenditures including installations of new equipment for the next twelve months; however, as we continue to grow our business by adding more energy systems, the cash requirements will increase. We believe that our cash and cash equivalents available at December 31, 2014 and our ability to control certain costs, including those related to general and administrative expenses, will enable us to meet our anticipated cash expenditures through March 31, 2016. Beyond March 31, 2016, we may need to raise additional capital through a debt financing or equity offering to meet our operating and capital needs. There can be no assurance, however, that we will be successful in our fundraising efforts or that additional funds will be available on acceptable terms, if at all.
 
If we are unable to raise additional capital in 2016 we may need to terminate certain of our employees and adjust our current business plan. Financial considerations may cause us to modify planned deployment of new energy systems and we may decide to suspend installations until we are able to secure additional working capital. We will evaluate possible acquisitions of, or investments in, businesses, technologies and products that are complementary to our business. However, we are not currently engaged in such discussions.
 
The Company’s operations are comprised of one business segment. Our business is selling energy in the form of electricity, heat, hot water and cooling to our customers under long-term sales agreements.

AMERICAN DG ENERGY INC.


Fiscal Year Ended December 31, 2014 Compared with Fiscal Year Ended December 31, 2013
 
Revenues

Revenues in 2014 were $8,567,553 compared to $7,461,880 for the same period in 2013, an increase of $1,105,673 or 14.8%. The increase in revenues was primarily due to higher energy production and units operational in the United Kingdom (UK). Our On-Site Utility energy revenues in 2014 increased to $7,808,933 compared to $7,164,226 for the same period in 2013, an increase of $644,707 or 9.0%. As part of our On-Site Utility energy revenue, the revenue recognized from demand response activity was $247,518 and $112,405, for the years ended December 31, 2014 and 2013, respectively. Our turnkey and other revenues in 2014 increased to $758,620 compared to $297,654 for the same period in 2013. The revenue from our turnkey projects can vary substantially per period.
 
During 2014, we operated 123 energy systems, at 69 locations, representing 8,186 kW of installed electricity plus thermal energy, compared to 109 energy systems at 64 locations, representing 7,278 kW of installed electricity plus thermal energy for the same period in 2013. The revenue per customer on a monthly basis is based on the sum of the amount of energy produced by our energy systems, which is derived by the monthly published price of energy (electricity, natural gas or oil) from our customers’ local utility, less the discounts we provide our customers. Our revenues commence as new energy systems become operational.
 
Cost of Sales
 
Cost of sales, including depreciation, in 2014 was $8,481,780 compared to $6,245,598 for the same period in 2013, an increase of $2,236,182 or 35.8%. The increase in expense was principally driven by the partial impairment of four sites totaling $723,438 in 2014, versus no site impairments in 2013. Also included in the cost of sales was an increase in depreciation expense of $461,124 to $1,843,817 in 2014, from $1,382,693 for the same period in 2013. In addition, driven by higher maintenance and fuels costs, as a result of more sites and higher gas prices in 2014, fuel, maintenance and installation costs increased by $1,051,620 to $5,914,525 in 2014 from $4,862,905 in 2013.
 
In 2014, our gross margins were 1.0% compared to 16.3% for the same period in 2013. The decrease was primarily due to higher maintenance, fuel and site impairment costs. Our On-Site Utility energy margins excluding site impairments and depreciation were at 30.6% in 2014 compared to 33.4% for the same period in 2013.
 
Operating Expenses
 
Our general and administrative expenses consist of executive staff, accounting and legal expenses, office space, general insurance and other administrative expenses. Our general and administrative expenses in 2014 were $3,238,141 compared to $2,940,833 for the same period in 2013, an increase of $297,308 or 10.1%. The increase was primarily due to additional legal staff, increased legal expense and increased external accounting and auditing expenses.
 
Our selling expenses consist of sales staff, commissions, marketing, travel and other selling related expenses including provisions for bad debt write-offs. The Company sells energy using both direct sales and commissioned agents. Our marketing efforts consisted of internet marketing, print literature, media relations and event driven direct mail. Our selling expenses in 2014 were $1,078,351 compared to $1,383,077 for the same period in 2013, a decrease of $304,726. The reduction in costs was principally due to lower spending in the UK, as EuroSite Power moved past the start up stage during which we spent more on marketing to gain market awareness.
 
Our engineering expenses consisted of technical staff and other engineering related expenses. The role of engineering is to evaluate potential customer sites based on technical and economic feasibility, manage the installed base of energy systems and oversee each new installation project. Our engineering expenses in 2014 were $897,445 compared to $1,018,914 for the same period in 2013, a decrease of $121,469 or 11.9%. The decrease in our engineering expenses was due to less salary and benefit costs due to lower headcount in 2014 compared to the same period in 2013. The reduction in salary and benefit costs was partially offset by higher engineering subcontracting expense.
 
Loss from Operations
 
The loss from operations in 2014 was $5,128,164 compared to $4,126,542 for the same period in 2013. The increase in the operating loss of $1,001,622 was principally due to site impairment expenses of $723,438 in 2014.

Other Income (Expense), Net

Our other income (expense), net, in 2014 was an expense of $2,042,234 compared to an expense of $986,286 for the same period in 2013. Other income (expense), net, includes interest and other income, interest expense, debt conversion inducement expense, loss on extinguishment of debt and change in fair value of warrant liability. Interest and other income was $92,928 in 2014 compared to $49,291 for the same period in 2013. The increase was primarily due to more invested funds. Interest expense was $1,402,493 in 2014 compared to $1,292,766 for the same period in 2013, a 8.5% increase due to more interest expense from increased convertible debenture at the EuroSite Power subsidiary. In 2014, the change in fair value of warrant liability resulted in income of $125,485 compared to $257,189 in 2013 (see “Note 6 – Warrant liability”). We also took a non-cash charge of $533,177 in 2014 for the extinguishment of old EuroSite Power convertible debt which was exchanged for new EuroSite Power convertible debt and we recorded a debt conversion inducement expense of $324,977 for the conversion of EuroSite convertible debt into common shares of EuroSite Power at favorable conversion rates.
 
Provision for Income Taxes
 
Our benefit from income taxes in 2014 was $645,040 compared to a provision of $13,450 for the same period in 2013. The favorable tax provision in 2014 was principally due to "Advanced Capital Allowances" (ECA) of $649,000 from the UK, whereby we receive a cash benefit that is an acceleration of tax relief on capital expenditures of co-generation equipment put into service at approved sites in the UK.
 
Noncontrolling Interest
 
The noncontrolling interest share in the losses in ADGNY and EuroSite Power was a loss of $636,464 in 2014 compared to a loss of $239,606 for the same period in 2013. Losses at EuroSite Power were up in 2014 over 2013 largely due to convertible debt conversion inducement and convertible debt extinguishment expenses.
 
Liquidity and Capital Resources
 
Consolidated working capital at December 31, 2014 was $13,303,032, compared to $11,881,175 at December 31, 2013. Included in working capital were cash and cash equivalents of $11,825,915 at December 31, 2014, compared to $9,804,291 at December 31, 2013. The increase in working capital was largely the result of cash received from our financing activities of $8,453,717, offset by capital expenditures of $5,649,433, and the net uses of funds in operating activities of $782,660.
  
Cash used in operating activities was $782,660 in 2014 compared to $1,553,257 for the same period in 2013. The Company's short and long-term receivables balance, including unbilled revenue, increased to $1,156,944, in 2014 compared to $1,046,385 at December 31, 2013, reducing $110,559 of cash due to increased sales. Amounts due to the Company from related parties decreased to $39,682 in 2014 compared to $304,288 at December 31, 2013, increasing cash $264,606. Our inventory decreased to $1,153,927 in 2014 compared to $2,246,335 at December 31, 2013, supplying $1,092,408 of cash.
 
Accounts payable decreased to $605,530 in 2014, compared to $871,079 at December 31, 2013, requiring $265,549 of cash. The amount due to related party increased to $630,805 in 2014, compared to $178,216 at December 31, 2013, providing $452,589 of cash.
 
During 2014, the investing activities of the Company's operations were expenditures for the purchase of property, plant and equipment for energy system installations. The Company used $5,649,433 for purchases and installation of energy systems, net of rebates and incentives of $27,500. The Company's financing activities provided $8,453,717 of cash in 2014 from the issuance of convertible debentures by Eurosite Power, the sale of the Company's common stock, the sale of common stock by EuroSite Power, a related party loan to EuroSite Power, offset by share repurchases of common stock by the Company and EuroSite Power and distributions to noncontrolling interest.

The Company’s On-Site Utility energy program allows customers to reduce both their energy costs and site carbon production by deploying combined heat and power technology on its customers’ premises at no capital cost to the customer. Therefore the Company's business model is capital intensive as the Company owns the On-Site Utility equipment. The Company believes that its existing resources, including cash and cash equivalents and future cash flow from operations, are sufficient to meet the working capital requirements of its existing business for the foreseeable future, including the next 12 months; however, as the Company continues to grow its business by adding more energy systems, the cash requirements will

19

AMERICAN DG ENERGY INC.


increase. Beyond March 31, 2016, the Company may need to raise additional capital through a debt financing or an equity offering to meet its operating and capital needs for future growth. There can be no assurance, however, that the Company will be successful in its fundraising efforts or that additional funds will be available on acceptable terms, if at all.
 
Our ability to continue to access capital could be impacted by various factors including general market conditions, interest rates, the perception of our potential future earnings and cash distributions, any unwillingness on the part of lenders to make loans to us and any deterioration in the financial position of lenders that might make them unable to meet their obligations to us. If these conditions continue and we cannot raise funds through a public or private debt financing, or an equity offering, our ability to grow our business might be negatively affected. In such case, the Company might need to suspend new installation of energy systems and significantly reduce its operating costs until market conditions improve.

Summary of Financial Transactions

The Company has raised the majority of its funds through convertible debentures, its subsidiaries convertible debentures, unregistered private placements and public offerings of its common stock.

On May 23, 2011 and November 30, 2011, the Company issued $19,400,000 aggregate principal amount of debentures to John Hatsopoulos, the Company’s Chief Executive Officer and a principal owner of the Company. See Financial Statements, Note 4 "Convertible debentures" for the details and a full history of these convertible debentures.

On August 28, 2013, after the closing of trading on the NYSE-MKT, the Company, entered into a subscription agreement with Charles T. Maxwell, the Company's Chairman of the Board, or the Investor, selling to the Charles T. Maxwell IRA an aggregate of 300,000 shares of the Company's Common Stock, $.001 par value per share, or the Securities, at a purchase price of $1.55 per share for an aggregate purchase price of $465,000.

On September 4, 2013, after the closing of trading on the NYSE-MKT, the Company, entered into a subscription agreement with Frost Gamma Investments Trust, or the Trust, an accredited investor, by selling to the Trust an aggregate of 333,334 shares of the Company's common stock at a per share price of $1.50 for an aggregate purchase price of $500,001.
    
On August 6, 2014, in a public offering, the Company issued; 2,650,000 shares of its common stock, three-year warrants to purchase up to 2,829,732 shares and five-year warrants to purchase an additional 112,538 to the underwriters with an exercise price of $1.8875 per share for net proceeds of $3,269,275.
    
On October 3, 2014, the Company consummated a series of transactions whereby, under an agreement with the holders of the Company’s existing 6% Senior Unsecured Convertible Debentures Due 2018, or the convertible debentures, it paid the interest due under the convertible debentures through the next semiannual payment date of November 25, 2014 by delivering to the holders of the convertible debentures 1,164,000 shares of common stock of its subsidiary EuroSite Power, which were owned by the Company. The Company also delivered 8,245,000 additional shares of EuroSite Power it owned to the holders of the convertible debentures for prepayment of all interest which would become due under the convertible debentures through the maturity date of May 25, 2018. Following the payment of all current and future interest under the convertible debentures, the Company exchanged the convertible debentures which bore interest at an annual rate of 6% for non-interest bearing convertible debentures with all other terms including the principal amount, maturity date, and conversion terms and privileges remaining unchanged.The face amount of the convertible debentures at December 31, 2014 was $19,400,000.
        
On June 14, 2013, EuroSite Power entered into subscription agreements with certain investors, including the Company, for a private placement of an aggregate principal amount of $4,000,000 of 4% Senior Convertible Notes Due 2015. In connection with the private placement, the Company exchanged certain notes it held, which had a principal balance of $1,100,000, for a like principal amount of the 4% Senior Convertible Notes Due 2015 and paid in cash any accrued but unpaid interest on those notes.

Effective April 15, 2014 and April 24, 2014 EuroSite Power, entered into subscription agreements with John N. Hatsopoulos, the Co-Chief Executive Officer, certain other investors and a principal owner of the Company for the sale of a $1,450,000, 4% Senior Convertible Note Due 2018.

On October 3, 2014, EuroSite Power, entered into convertible note amendment agreements, or the Note Amendment Agreements, with the Company, John N. Hatsopoulos and a principal owner of the Company, as well as certain separate convertible note conversion agreements, or the Note Conversion Agreements, with certain other investors, whereby

20

AMERICAN DG ENERGY INC.


$3,050,000 of EuroSite Power's convertible notes were converted into 6,100,000 shares of Eurosite Power common stock at a conversion price of $0.50 per share.
 
On September 19, 2014, John Hatsopoulos loaned EuroSite Power $3,000,000 without interest pursuant to a promissory note (the "Loan"). The Loan matures upon a substantial capital raise or on September 19, 2019. Prepayment of principal may be made at any time without penalty. The proceeds of the Loan will be used in connection with the development and installation of current and new energy systems in the United Kingdom and Europe. On December 30, 2014, the EuroSite Power amended and restated the existing promissory note to provide for interest at a rate of 1.85%.

See Financial Statements, Note 4 "Convertible debentures" for the details of these convertible notes and convertible notes amendment agreements.

Critical Accounting Policies
 
The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Management believes the following critical accounting policies involve more significant judgments and estimates used in the preparation of our consolidated financial statements.

Partnerships, Joint Ventures and Entities under Common Control
 
Certain contracts are executed jointly through partnerships and joint ventures with unrelated third parties. The Company consolidates all joint ventures and partnerships in which it owns, directly or indirectly, 50% or more of the membership interests and any Variable Interest Entities (VIE) in which it has a controlling financial interest. Determination of a controlling financial interest in a VIE requires management to identify and analyze all explicit and implicit variable interests in the entity and determine whether the VIE model applies. It also requires management to analyze various factors in order to determine who if anyone is the primary beneficiary of the entity. These analyses and determinations require a high level judgment. All significant intercompany accounts and transactions are eliminated. Noncontrolling interest in net assets and earnings or losses of consolidated entities are reflected in the caption “Noncontrolling interest” in the accompanying consolidated financial statements. Noncontrolling interest adjusts the consolidated results of operations to reflect only the Company’s share of the earnings or losses of the consolidated entities.
 
Property and Equipment and Depreciation and Amortization
 
Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method at rates sufficient to write off the cost of the applicable assets over their estimated useful lives. Repairs and maintenance are expensed as incurred.
 
The Company reviews the useful life of its energy systems on a quarterly basis or whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable or that the useful lives of the assets are no longer appropriate. The Company evaluates the recoverability of its long-lived assets when impairment is indicated by comparing the net book value of the asset group to the estimated future undiscounted cash flows attributable to such assets. The useful life of the Company’s energy systems is the lesser of the economic life of the asset or the term of the underlying contract with the customer, typically 12 to 15 years. If impairment is indicated, the asset is written down to its estimated fair value.
 
The Company receives rebates and incentives from various utility companies which are accounted for as a reduction in the book value of the assets. The rebates are payable from the utility to the Company and are applied against the cost of construction, therefore reducing the book value of the installation. As a reduction of the facility construction costs, these rebates are treated as an investing activity in the statements of cash flows. The rebates received by the Company from the utilities that apply to the cost of construction are one time rebates based on the installed cost, capacity and thermal efficiency of installed unit and are earned upon the installation and inspection by the utility and are not related to or subject to adjustment based on the future operating performance of the installed units. The rebate agreements with utilities are based on standard terms and conditions, the most significant being customer eligibility and post-installation work verification by a specific date.

Stock-Based Compensation

21

AMERICAN DG ENERGY INC.


 
Stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as an expense in the consolidated statements of operations over the requisite service period. The fair value of stock options granted is estimated using the Black-Scholes option pricing valuation model. The Company recognizes compensation on a straight-line basis for each separately vesting portion of the option award. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on the Company’s historic volatility over the expected life of the option grant. The average expected life is estimated using the simplified method for “plain vanilla” options. The simplified method determines the expected life in years based on the vesting period and contractual terms as set forth when the award is made. The Company uses the simplified method for awards of stock-based compensation since it does not have the necessary historical exercise and forfeiture data to determine an expected life for stock options. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term which approximates the expected life assumed at the date of grant. When options are exercised the Company normally issues new shares.
  
Revenue Recognition
 
Revenue from energy contracts is recognized when electricity, heat, and chilled water is produced by the cogeneration systems on-site. The Company bills each month based on various meter readings installed at each site. The amount of energy produced by on-site energy systems is invoiced, as determined by a contractually defined formula. Under certain energy contracts, the customer directly acquires the fuel to power the systems and receives credit for that expense from the Company. The credit is recorded as a reduction of revenue and as reduction of cost of fuel. Revenues from operation, including shared savings are recorded when provided and verified. Maintenance service revenue is recognized over the term of the agreement and is billed on a monthly basis in arrears. Customers may buy out their long-term obligation under energy contracts and purchase the underlying equipment from the Company. Any resulting gain on these transactions is recognized over the payment period in the accompanying consolidated statements of operations.
 
In some cases, the customer may choose to own the energy system rather than have it owned by American DG Energy. In this case, the Company accounts for revenue, or turnkey revenue, and costs using the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting, revenues are recognized by applying percentages of completion to the total estimated revenues for the respective contracts. Costs are recognized as incurred. The percentages of completion are determined by relating the actual cost of work performed to date to the current estimated total cost at completion of the respective contracts. When the estimate on a contract indicates a loss, the Company’s policy is to record the entire expected loss, regardless of the percentage of completion. The excess of contract costs and profit recognized to date on the percentage-of-completion accounting method in excess of billings is recorded as unbilled revenue. Billings in excess of related costs and estimated earnings is recorded as deferred revenue.
 
At times the Company will enter into a sales arrangement with a customer to construct and sell an energy system and provide energy and maintenance services over the term of the contract. Based on the fact that the Company sells each deliverable to other customers on a stand-alone basis, the Company has determined that each deliverable has a stand-alone value. Additionally, there are no rights of return relative to the delivered items; therefore, each deliverable is considered a separate unit of accounting. Revenue is allocated to each element based upon its relative fair value which is determined based on the estimated price of the deliverables when sold on a standalone basis. Revenue related to the construction of the energy system is recognized using the percentage-of-completion method as the unit is being constructed. Revenue from the sale of energy is recognized when electricity, heat, and chilled water is produced by the energy system, and revenue from maintenance services is recognized over the term of the maintenance agreement.

The Company is able to participate in the demand response market. Demand response programs provide payments for either the reduction of electricity usage or low capacity utilization throughout a utility territory. For the year ended December 31, 2014 and 2013, the revenue recognized from demand response activity was $247,518 and $112,405, respectively.
 
Income Taxes
 
As part of the process of preparing its consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as depreciation and certain accrued liabilities for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Company’s consolidated balance sheet. The Company must then assess the likelihood that its

22

AMERICAN DG ENERGY INC.


deferred tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, the Company must establish a valuation allowance.
 
The Company is allowed to recognize the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The amount recognized is the amount that represents the largest amount of tax benefit that is greater than 50% likely of being ultimately realized. A liability is recognized for any benefit claimed, or expected to be claimed, in a tax return in excess of the benefit recorded in the financial statements, along with any interest and penalties (if applicable) on that excess. In addition, the Company is required to provide a tabular reconciliation of the change in the aggregate unrecognized tax benefits claimed, or expected to be claimed, in tax returns and disclosure relating to the accrued interest and penalties for unrecognized tax benefits. Discussion is also required for those uncertain tax positions where it is reasonably possible that the estimate of the tax benefit will change significantly in the next twelve months.

Impact of New Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and the International Financial Reporting Standards. This guidance supersedes previously issued guidance on revenue recognition and gives a five step process an entity should follow so that the entity recognizes revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for our fiscal 2017 reporting period and must be applied either retrospectively during each prior reporting period presented or retrospectively with the cumulative effect of initially applying this guidance recognized at the date of the initial application. Early adoption is not permitted. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15 "Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern". The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.
 
Seasonality
 
The majority of our heating systems sales are in the winter and the majority of our chilling systems sales are in the summer.

Inflation
 
We install, maintain, finance, own and operate complete on-site CHP systems that supply, on a long-term, contractual basis, electricity and other energy services. We sell the energy to customers at a guaranteed discount rate to the rates charged by conventional utility suppliers. Our customers benefit from a reduction in their current energy bills without the capital costs and risks associated with owning and operating a CHP or chiller system. Inflation will cause an increase in the rates charged by conventional utility suppliers, and since we bill our customers based on the electric utility rates, our pricing will increase in tandem and positively affect our revenue. However, inflation might cause both our investment and cost of goods sold to increase, therefore lowering our return on investment and depressing our gross margins.
 
Off Balance Sheet Arrangements
 
The Company has no material off balance sheet arrangements.

Management’s Evaluation of Disclosure Controls and Procedures:
 
Our disclosure controls and procedures are designed to provide reasonable assurance that the control system’s objectives will be met. Our management, including our Co-Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report, or the Evaluation Date, have concluded that as of the Evaluation Date, our disclosure controls and procedures were not effective.

For these purposes, the term disclosure controls and procedures of an issuer means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
 
Management’s Annual Report on Internal Control over Financial Reporting:
 
The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting in accordance with the Exchange Act. Management, including our Co-Chief Executive Officer and Chief Financial Officer, conducted an evaluation of our internal control over financial reporting based on the framework and criteria established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission in 1992. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion of this evaluation. Based on this evaluation, management concluded that the Company’s internal control over financial reporting is not effective as of December 31, 2014. Considerable progress was made during 2014 with the addition of competent staff, competent consultants and changes in processes, however, management has concluded that it is not yet satisfied with the number of controls and the number of tests of controls over the manual revenue recognition process of the Company.
  
Our management, including our Co-Chief Executive Officer and Chief Financial Officer, do not expect that our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

This Annual Report on Form 10-K does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this Annual Report on Form 10-K.

Changes to Disclosure Controls and Procedures and Changes to Internal Controls over Financial Reporting:

Remediation steps taken in 2014 the appointment of a new Chief Financial Officer with public company experience, an internal securities counsel, a GAAP consultant and an experienced accounting firm to advise management on complex accounting issues and disclosure controls and processes. In addition, processes were enhanced during the year to ensure complex

To the Board of Directors and Stockholders of

American DG Energy Inc.:
 
We have audited the accompanying consolidated balance sheet of American DG Energy Inc. and subsidiaries (the “Company”) as of December 31, 2014 and the related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated financial statements based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform our audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.
 
In our opinion, the 2014 consolidated financial statements referred to above, present fairly, in all material respects, the consolidated financial position of American DG Energy Inc. and subsidiaries as of December 31, 2014 and the results of their operations and their cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

AMERICAN DG ENERGY INC.


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — The Company:
 
American DG Energy Inc., or the Company, we, our or us, distributes, owns, operates and maintains clean, on-site energy systems that produce electricity, hot water, heat and cooling. The Company's business model is to own the equipment that it installs at customers' facilities and to sell the energy produced by these systems to its customers on a long-term contractual basis at prices guaranteed to the customer to be below conventional utility rates. The Company calls this business the American DG Energy “On-Site Utility”.
 
The Company was incorporated as a Delaware corporation on July 24, 2001 to install, own, operate and maintain complete DG systems, or energy systems, and other complementary systems at customer sites and sell electricity, hot water, heat and cooling energy under long-term contracts at prices guaranteed to the customer to be below conventional utility rates.

The Company derives revenues from selling energy in the form of electricity, heat, hot water and cooling to its customers under long-term energy sales agreements (with a typical term of 10 to 15 years). The energy systems are generally owned by the Company and are installed in its customers’ buildings. Each month the Company obtains readings from energy meters to determine the amount of energy produced for each customer. The Company multiplies these readings by the appropriate published price of energy (electricity, natural gas or oil) from its customers’ local energy utility, to derive the value of its monthly energy sale, less the applicable negotiated discount. The Company’s revenues per customer on a monthly basis vary based on the amount of energy produced by its energy systems and the published price of energy (electricity, natural gas or oil) from its customers’ local energy utility that month. The Company’s revenues commence as new energy systems become operational. As of December 31, 2014, the Company had 123 energy systems operational. In some cases the customer may choose to own the system rather than have it owned by American DG Energy.
 
Note 2 — Summary of significant accounting policies:
 
Principles of Consolidation and Basis of Presentation:
 
The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of the Company and entities in which it has a controlling financial interest. Those entities include the Company's 51.0% joint venture, American DG New York, LLC, or ADGNY, and its 50.1% owned subsidiary EuroSite Power Inc., or EuroSite Power. The interests in underlying energy system projects in the joint venture vary between the Company and its joint venture partner. As the controlling partner, all major decisions in ADGNY are made by the Company according to the joint venture agreement. Distributions, however, are made based on the economic ownership. The economic ownership is calculated by the amount invested by the Company and the noncontrolling partner in each site. Each quarter the Company calculates a year-to-date profit/loss for each site that is part of ADGNY and the noncontrolling interest percent ownership in each site is applied to determine the noncontrolling interest share in the profit/loss. The Company follows the same calculation regarding available cash and a cash distribution is made to the noncontrolling interest partner each quarter. On the Company’s balance sheet, noncontrolling interest represents the partner’s investment in the entity, plus its share of after tax profits less any cash distributions. The Company owned a controlling 51.0% legal interest and had a 62.5% economic interest in ADGNY as of December 31, 2014.

As of December 31, 2014 and December 31, 2013, the Company owned a 50.1% and a 70.7%, interest in EuroSite Power, respectively, and has consolidated EuroSite Power into its financial statements in both years in accordance with GAAP.

The Company has consolidated the operating results and financial position of EuroSite Power as it has determined it has a controlling financial interest in EuroSite Power. This determination was based on application of the variable interest entity (VIE) model which determines whether a controlling financial interest exists by other than majority voting ownership. In applying the VIE model, the Company considered the explicit and implicit variable interests which exist in EuroSite Power including its own and its ability to direct the activities of EuroSite Power which most significantly effect it’s economic performance and the Company’s obligation to absorb the expected losses of EuroSite Power.  In addition to its equity ownership in EuroSite Power, the Company has an implicit variable interest in EuroSite Power through its guarantee of the long term convertible indebtedness of EuroSite Power. This results in the Company’s voting ownership being disproportional to its obligation to absorb the expected losses of EuroSite Power. This combined with the fact that substantially all of EuroSite Power’s  activities either involve or are conducted on behalf of the Company results in EuroSite Power being considered a VIE.

F-7

AMERICAN DG ENERGY INC.


The current level of the Company’s ownership results in the Company’s ability to control the activities which most significantly effect the economic performance of EuroSite  Power. This combined with the Company’s obligation to absorb losses which could be significant to EuroSite Power qualify the Company as the primary beneficiary of EuroSite Power. As the primary beneficiary of a VIE, the Company is required to consolidate the operating results and financial position of the VIE.

On July 2, 2013, the Company declared a special dividend of one share of EuroSite Power common stock for every ten shares of American DG Energy common stock (“special dividend”). The special dividend was paid on August 15, 2013, to stockholders of record as of the close of business on July 25, 2013. In connection with this transaction, the Company issued to its stockholders an aggregate of 4,880,679 shares of EuroSite Power common stock that it owns.

The Company provides a guarantee with respect to the outstanding third party convertible indebtedness under EuroSite Power’s convertible debentures which it was not contractually obligated to provide. During 2013, the Company loaned $1,100,000 to EuroSite Power which it was not contractually obligated to do. The loan was made to facilitate deployment of new energy systems and the loan was ultimately converted into common stock of EuroSite Power. The Company also helps facilitate and assists EuroSite Power in obtaining additional sources of financing.

The Company’s operations are comprised of one business segment. The Company’s business is selling energy in the form of electricity, heat, hot water and cooling to its customers under long-term sales agreements. The Company’s revenue is generated in the United States of America and in the United Kingdom. During the years ended December 31, 2014 and 2013 revenue generated in the United States amounted to $6,989,680 and $6,623,001, respectively, and revenue generated in the United Kingdom amounted to $1,577,873 and $838,879 respectively.  At December 31, 2014, $18,536,250 of the Company’s long lived assets were located in the United States of America and $6,348,905 were located in the United Kingdom.  At December 31, 2013, $17,900,959 of the Company’s long lived assets were located in the United States of America and $4,030,330 were located in the United Kingdom.

The Company has experienced total net losses since inception of approximately $35.2 million. For the foreseeable future, the Company expects to experience continuing operating losses and negative cash flows from operations as its management executes the current business plan. The Company believes that its existing resources, including cash and cash equivalents and future cash flow from operations, are sufficient to meet the working capital requirements of its existing business for the foreseeable future, including the next twelve months; however, as the Company continues to grow its business by adding more energy systems, the cash requirements will increase. Beyond March 31, 2016, the Company may need to raise additional capital through a debt financing or an equity offering to meet its operating and capital needs. There can be no assurance, however, that the Company will be successful in its fundraising efforts or that additional funds will be available on acceptable terms, if at all.
 
In 2014, the Company raised $8,453,717, net of issuance costs, share repurchases and distributions, from the sale of the Company and its subsidiary's common stock, its subsidiaries loans and convertible debt. If the Company is unable to raise additional capital in 2016 it may need to terminate certain of its employees and adjust its current business plan. Financial considerations may cause the Company to modify planned deployment of new energy systems and may decide to suspend installations until it is able to secure additional working capital. The Company will evaluate possible acquisitions of, or investments in, businesses, technologies and products that are complementary to its business; however, the Company is not currently engaged in such discussions.
 
Use of Estimates
 
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
 
Revenue Recognition
 
Revenue from energy contracts is recognized when electricity, heat, and chilled water is produced by the cogeneration systems on-site. The Company bills each month based on various meter readings installed at each site. The amount of energy produced by on-site energy systems is invoiced, as determined by a contractually defined formula. Under certain energy contracts, the customer directly acquires the fuel to power the systems and receives credit for that expense from the Company. The credit is recorded as a cost of sale. Revenues from operations, including shared savings are recorded

F-8

AMERICAN DG ENERGY INC.


when provided and verified. Maintenance service revenue is recognized over the term of the agreement and is billed on a monthly basis in arrears.
 
In some cases, the customer may choose to own the energy system rather than have it owned by American DG Energy. In this case, the Company accounts for revenue, or turnkey revenue, and costs using the percentage-of-completion method of accounting. Under the percentage-of-completion method of accounting, revenues are recognized by applying percentages of completion to the total estimated revenues for the respective contracts. Costs are recognized as incurred. The percentages of completion are determined by relating the actual cost of work performed to date to the current estimated total cost at completion of the respective contracts. When the estimate on a contract indicates a loss, the Company records the entire expected loss, regardless of the percentage of completion. The excess of contract costs and profit recognized to date on the percentage-of-completion accounting method in excess of billings is recorded as unbilled revenue. Billings in excess of related costs and estimated earnings is recorded as deferred revenue.
 
Customers may buy out their long-term obligation under energy contracts and purchase the underlying equipment from the Company. Any resulting gain on these transactions is recognized over the payment period in the accompanying consolidated statements of operations.
 
The Company is able to participate in the demand response market and receive payments due to the availability of its energy systems. Demand response programs provide payments for either the reduction of electricity usage or the increase in electricity production during periods of peak usage throughout a utility territory. For the year ended December 31, 2014 and 2013, the revenue recognized from demand response activity was $247,518 and $112,405, respectively.
 
Cash and Cash Equivalents
 
The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The Company has cash balances in certain financial institutions in amounts which occasionally exceed current federal deposit insurance limits. The financial stability of these institutions is continually reviewed by senior management. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents.
 
Concentration and Credit Risk
 
Financial instruments, which potentially subject the Company to concentrations of credit risk, consist of highly liquid cash equivalents and trade receivables. The Company’s cash equivalents are placed with certain financial institutions and issuers. As of December 31, 2014, the Company had a balance of $10,771,457 in cash and cash equivalents that exceeded the Federal Deposit Insurance Corporation limit.

During the years ended December 31, 2014 and 2013, one customer accounted for 11.0% and 12.0% of revenue, respectively.
 
Accounts Receivable
 
The Company maintains receivable balances primarily with customers located throughout New York, New Jersey and the United Kingdom. The Company reviews its customers’ credit history before extending credit and generally does not require collateral. An allowance for doubtful accounts is established based upon factors surrounding the credit risk of specific customers, historical trends and other information. Generally, such losses have been within management’s expectations. Bad debt is written off when identified.

At December 31, 2014 and 2013, the allowance for doubtful accounts was $112,000 and $183,201, respectively. Included in accounts receivable are amounts from four major customers accounting for approximately 27.0% and 35.0% of total accounts receivable for the years ended December 31, 2014 and 2013, respectively.

Inventory
 
Inventories are stated at the lower of cost or market, valued on a first-in, first-out basis. Inventory is reviewed periodically for slow-moving and obsolete items. As of December 31, 2014 and 2013, there were no reserves or write-downs recorded against inventory.

Supply Concentrations
 

F-9

AMERICAN DG ENERGY INC.


Most of the Company’s cogeneration unit purchases for the years ended December 31, 2014 and 2013 were from one vendor (see “Note 8 - Related parties”). The Company believes there are sufficient alternative vendors available to ensure a constant supply of cogeneration units on comparable terms. However, in the event of a change in suppliers, there could be a delay in obtaining units which could result in a temporary slowdown of installing additional income producing sites. In addition, the majority of the Company’s units are installed and maintained by the noncontrolling interest holder or maintained by Tecogen Inc., or Tecogen (see “Note 8 - Related parties”). The Company believes there are sufficient alternative vendors available to ensure a constant supply of maintenance and installation services on comparable terms. However, in the event of a change of vendor, there could be a delay in installation or maintenance services.
 
Property, Plant and Equipment
 
Property, plant and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method at rates sufficient to write off the cost of the applicable assets over their estimated useful lives. Repairs and maintenance are expensed as incurred.
 
The Company reviews the useful life of its energy systems on a quarterly basis or whenever events or changes in business circumstances indicate that the carrying value of the assets may not be fully recoverable or that the useful lives of the assets are no longer appropriate. The Company evaluates the recoverability of its long-lived assets when potential impairment is indicated by comparing the remaining net book value of the assets to the estimated future undiscounted cash flows attributable to such assets. The useful life of the Company’s energy systems is the lesser of the economic life of the asset or the term of the underlying contract with the customer, typically 12 to 15 years. If impairment is indicated, the asset is written down to its estimated fair value based on a discounted cash flow analysis. During 2014, the Company recorded asset impairment losses totaling $723,438 relating to certain of its energy systems as a result of changing or unexpected conditions with respect to the energy systems which impact the estimated future cash flows. The conditional changes impacting the estimated future cash flows related to these assets resulted from changes in the level of demand for electricity and/or hot water at particular installations, finalization of start-up period customization at particular installations and/or price changes in electrical and natural gas rates, all of which impacted estimated future cash flows.
 
The Company receives rebates and incentives from various utility companies which are accounted for as a reduction in the book value of the assets. The rebates are payable from the utility to the Company and are applied against the cost of construction, therefore reducing the book value of the installation. As a reduction of the facility construction costs, these rebates are treated as an investing activity in the statements of cash flows. The rebates received by the Company from the utilities that apply to the cost of construction are one time rebates based on the installed cost, capacity and thermal efficiency of the installed unit and are earned upon the installation and inspection by the utility and are not related to or subject to adjustment based on the future operating performance of the installed units. The rebate agreements with utilities are based on standard terms and conditions, the most significant being customer eligibility and post-installation work verification by a specific date. During 2014 and 2013, the amount of rebates applied to the cost of construction was $27,500 and $285,718, respectively.
 
Stock Based Compensation
 
Stock based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as an expense in the consolidated statements of operations over the requisite service period. The fair value of stock options granted is estimated using the Black-Scholes option pricing valuation model. The Company recognizes compensation on a straight-line basis over the expected life for each separately vesting portion of the option award. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on the Company’s historic volatility over the expected life of the option grant. The average expected life is estimated using the simplified method for “plain vanilla” options. The simplified method determines the expected life in years based on the vesting period and contractual terms as set forth when the award is made. The Company uses the simplified method for awards of stock-based compensation since it does not have the necessary historical exercise and forfeiture data to determine an expected life for stock options. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term which approximates the expected life assumed at the date of grant. When options are exercised the Company normally issues new shares.
 
See “Note 5 – Stockholders’ equity” for a summary of the restricted stock and stock option activity under the Company’s stock-based employee compensation plan for the years ended December 31, 2014 and 2013, respectively.

Loss per Common Share
 

F-10

AMERICAN DG ENERGY INC.


The Company computes basic loss per share by dividing net income (loss) for the period by the weighted average number of shares of common stock outstanding during the period. The Company computes diluted earnings per common share using the treasury stock method. For purposes of calculating diluted earnings per share, the Company considers its shares issuable in connection with convertible debentures, stock options and warrants to be dilutive common stock equivalents when the exercise price is less than the average market price of its common stock for the period. For the year ended December 31, 2014, the Company excluded 15,763,083 anti-dilutive shares resulting from exercise of stock options, warrants and shares issuable in connection with convertible debentures, and for the year ended December 31, 2013, the Company excluded 12,088,313 anti-dilutive shares resulting from exercise of stock options, warrants and unvested restricted stock. All shares issuable for both years were anti-dilutive because of the reported net loss.

Income Taxes
 
As part of the process of preparing its consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as depreciation and certain accrued liabilities for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Company’s consolidated balance sheet. The Company must then assess the likelihood that its deferred tax assets will be recovered from future taxable income and to the extent it believes that recovery is not likely, the Company must establish a valuation allowance.
 
The Company is allowed to recognize the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The amount recognized is the amount that represents the largest amount of tax benefit that is greater than 50.0% likely of being ultimately realized. A liability is recognized for any benefit claimed, or expected to be claimed, in a tax return in excess of the benefit recorded in the financial statements, along with any interest and penalties (if applicable) on that excess.

The tax years 2003 through 2013 remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in the United States, as carry forward attributes generated in years past may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they are or will be used in a future period. The Company is currently not under examination by the Internal Revenue Service or any other jurisdiction for any tax years. The Company did not recognize any interest and penalties associated with unrecognized tax benefits in the accompanying consolidated financial statements. The Company would record any such interest and penalties as a component of interest expense. The Company does not expect any material changes to the unrecognized benefits within twelve months of the reporting date.
 
Fair Value of Financial Instruments
 
The Company’s financial instruments are cash and cash equivalents, short-term investments, accounts receivable, accounts payable, convertible debentures and amounts due to/from related parties. The recorded values of cash and cash equivalents, accounts receivable, accounts payable and amounts due to/from related parties approximate their fair values based on their short-term nature. The warrant liability is recorded at fair value. The loan payable to related party is at fair value. The carrying value of the convertible debentures on the balance sheet at December 31, 2014 approximates fair value as the terms approximate those currently available for similar instruments. See “Note 9 - Fair value measurements.”

Reclassifications

In our 2013 Consolidated Balance Sheet, certain amounts between Convertible debentures and Convertible debentures due related parties have been reclassified to conform with current year presentation.
 
New Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and the International Financial Reporting Standards. This guidance supersedes previously issued guidance on revenue recognition and gives a five step process an entity should follow so that the entity recognizes revenue that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This new guidance will be effective for our fiscal 2017 reporting period and must be applied either retrospectively during each prior reporting period presented or retrospectively with the cumulative effect of initially applying

F-11

this guidance recognized at the date of the initial application. Early adoption is not permitted. We are currently evaluating the impact of the adoption of this ASU on our consolidated financial statements.

In August 2014, the FASB issued ASU 2014-15 "Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern". The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on our consolidated financial statements.

Note 4 — Convertible debentures:

American DG Energy Convertible Debentures

On May 23, 2011, the Company issued $12,500,000 aggregate principal amount of debentures to John N. Hatsopoulos, the Company’s Co-Chief Executive Officer, and a principal owner of the Company. The debentures mature on May 25, 2018 and accrue interest at the rate of 6.0% per annum payable on a semi-annual basis. At the holder’s option, the debentures may be converted into shares of the Company’s common stock at a conversion price of $2.20 per share, subject to adjustment in certain circumstances. The Company has the option to redeem at 115% of Par Value any or all of the debentures after May 25, 2016. The debentures canceled the revolving line of credit agreement with John N. Hatsopoulos, which as of May 23, 2011 had a principal amount outstanding of $2,400,000.
 
On November 30, 2011, the Company issued an additional $6,900,000 aggregate principal amount of debentures to the same principal owner of the Company. The debentures mature on May 25, 2018 and accrue interest at the rate of 6.0% per annum payable on a semi-annual basis. At the holder’s option, the debentures may be converted into shares of the Company’s common stock at a conversion price of $2.20 per share, subject to adjustment in certain circumstances. The Company has the option to redeem at 115% of Par Value any or all of the debentures after May 25, 2016.
 
On January 10, 2013, at the request of all holders of the Company’s Senior Unsecured Convertible Debentures, due 2018, the Company modified through a third amendment the terms of the interest payment due to the holders. Under the terms of the third amendment, the holders agreed to receive interest payments on an annual basis starting on November 25, 2013 (instead of semi-annual interest payments) and that the Company use the average daily closing price of the Common Stock 10 business days before the interest payment due date in order to determine the conversion price. All other terms and conditions of the debentures, including interest rate and maturity date remained the same.

On May 24, 2013, at the request of all holders of the Company’s Senior Unsecured Convertible Debentures, due 2018, the Company modified through a fourth amendment the terms of the interest payment due to the holders. Under the terms of the fourth amendment, the holders agreed to receive semi-annual interest payments on May 25th and November 25th in shares of the Company's common stock instead of cash for 2012, 2013 and 2014, provided that the Company's shares are listed on a National Securities Exchange. Under the terms of this amendment, for the May semi-annual interest payment, the Company will use the April average daily closing price of the Common Stock in order to determine the conversion price and for the

F-12

AMERICAN DG ENERGY INC.


November semi-annual interest payment the Company will use the October average daily closing price of the Common Stock in order to determine the conversion price. All other terms and conditions of the debentures, including interest rate and maturity date remained the same.

On May 25, 2013, the total interest due to the debenture holders was $582,000 and in connection with the amendment the Company issued to the debenture holders 316,462 shares of common stock at $1.84 per share which was the average price of the Company's common stock during the month of April. In connection with this transaction, the Company recorded a reduction of $53,511 of non-cash interest expense, which was the difference between the average stock price and the fair market value on May 25, 2013.

On July 2, 2013, the Company declared a special dividend of one share of EuroSite Power common stock for every ten shares of American DG Energy common stock (“special dividend”). The special dividend was paid on August 15, 2013, to stockholders of record as of the close of business on July 25, 2013. In connection with this transaction the Company, issued to its stockholders an aggregate of 4,880,679 shares of EuroSite Power common stock that it owns. Affiliates may sell the securities only after a 6 month holding period pursuant to the provisions of the SEC's Rule 144.

On August 15, 2013, in connection with the special dividend, the Company modified the conversion price of the 6%, $19,400,000 debentures issued on May 23, 2011 and November 30, 2011 from $2.20 to $2.11 per share. The adjustment to the conversion price was not an automatic adjustment pursuant to the original terms of the debentures. Accordingly, the adjustment to the conversion price was accounted for as a modification under ASC 470. The modification of the convertible debt instrument resulted in an increase in the fair value of the embedded conversion option and the carrying amount of the debt instrument was reduced by approximately $649,000. This debt discount is being amortized over the remaining term of the debt. In accordance with ASC 820, the fair value of the conversion option at the date of modification was determined by utilizing a binomial lattice model with the following key assumptions:
Company stock price
$1.64 per share
Risk -free rate
1.43% - 1.45%
Term
4.78 years
Volatility
68.8%

On November 25, 2013, the total interest due to the debenture holders was $582,000 and in connection with the amendment the Company issued to the debenture holders 377,391 shares of common stock at $1.54 per share which was the average price of the Company's common stock during the month of October. In connection with this transaction, the Company recorded an additional charge of $59,562 of non-cash interest expense, which was the difference between the average stock price and the fair market value on November 25, 2013.

On May 25, 2014, the total interest due to the debenture holders was $582,000 and the Company issued to the debenture holders 260,154 shares of common stock at $2.24 per share which was the average price of the Company's common stock during the month of April. In connection with this transaction, the Company recorded an additional charge of $42,368 of non-cash interest expense, which was the difference between the average stock price and the fair market value on May 25, 2014.

On October 3, 2014, the Company consummated a series of transactions whereby, under an agreement with John N. Hatsopoulos and a principal owner of the Company whereby, the holders of the Company’s existing 6% Senior Unsecured Convertible Debentures Due 2018, paid the interest due under the convertible debentures through the next semiannual payment date of November 25, 2014 by delivering to the holders of the convertible debentures 1,164,000 shares of common stock of its subsidiary EuroSite Power, which were owned by the Company and which had a market value of $582,000. The Company also delivered 8,245,000 additional shares of EuroSite Power it owned with an aggregate market value of $4,122,500 to the holders of the convertible debentures for prepayment of all interest which would become due under the convertible debentures through the maturity date of May 25, 2018. In connection with these transactions, the Company delivered to the holders of the convertible debentures three-year warrants with an exercise price per share of $0.60 to purchase an additional 1,164,000 shares of EuroSite Power from the Company with an aggregate market value of $84,911.

These transactions are reciprocal transfers and thus exchanges of non-monetary assets which are accounted for at fair value. The fair value recognized in recording the exchanges equaled the fair market value of the EuroSite Power shares relinquished and the amount of cash the counterparties to the exchange could have received in cash in lieu of accepting the shares, which amounts were identical with the exception of the additional value ascribed to the warrants of $84,911. No gain or loss was recognized relative to these transactions under ASC 810-10-45-23 since the Company retained a controlling financial

F-13

AMERICAN DG ENERGY INC.


interest in EuroSite Power following these transactions. Accordingly, these transactions were accounted for as equity transactions with any difference between the fair value assigned and the necessary adjustment to noncontrolling interest being assigned to the additional paid-in capital of the Company.

Following the payment of all current and future interest under the convertible debentures, the Company exchanged the convertible debentures which bore interest at an annual rate of 6% for non-interest bearing convertible debentures, the 2014 Convertible Debentures, with all other terms including the principal amount, maturity date, and conversion terms and privileges remaining unchanged.

The exchange of debentures was not considered to be an extinguishment under ASC 470-50 as the debt instruments exchanged were not considered to have substantially different terms and, accordingly, no gain or loss was recognized. The existing basis in the convertible debentures prior to the exchange was carried over and an additional discount equal to the fair value of the EuroSite Power shares exchanged for future interest and the fair value of the warrants was recorded. The total discount, including the fair value of the warrant of $84,911, was $4,207,411. The revised discount is being amortized to interest expense on the interest method. The effective interest rates to fully accrete the 2014 Convertible Debentures to their face value at maturity is 7.8%.

The unamortized discount at December 31, 2014 was $4,523,051 and non-cash interest expense related to amortization of the discount in the year ended December 31, 2014 was $162,486.
    
Eurosite Power Convertible Debentures

On February 26, 2013, EuroSite Power issued a promissory note in the amount of $1,100,000 to the Company. Under the terms of the agreement EuroSite Power was to pay interest at a rate of 6.0% per annum payable quarterly in arrears.  

                On June 14, 2013, EuroSite Power entered into subscription agreements with certain investors, including the Company, for a private placement of an aggregate principal amount of $4,000,000 of 4% Senior Unsecured Convertible Notes Due 2015, or the Notes. In connection with the private placement, the Company exchanged the promissory note in the aggregate principal amount of $1,100,000, originally issued on February 26, 2013 for a like principal amount of the Notes and cash paid for any accrued but unpaid interest. Included among the investors subscribing for the Notes are: Bruno Meier, a director of EuroSite, in the amount of $250,000; Joan Giacinti, a director of the Company and EuroSite Power, in the amount of $300,000; Charles T. Maxwell, Chairman of the Board of Directors of the Company, in the amount of $250,000; Nettlestone Enterprises Limited, a shareholder of both Eurosite Power and the Company, in the amount of $300,000; Perastra Management S.A., an investor in the Company and EuroSite Power, in the amount of $1,500,000; and Yves Micheli, an investor in EuroSite Power, in the amount of $300,000. The proceeds of the offering of the Notes will be used in connection with the development and installation of current and new energy systems, business development and for general corporate purposes.

                The holders of the Notes are subject to and entitled to the benefits of the 4% Senior Convertible Notes due 2015 Noteholders Agreement, dated June 14, 2013, or the Noteholders Agreement. The Notes will mature on June 14, 2015 and will accrue interest at the rate of 4% per annum payable in cash on a semi-annual basis. At the Investor's option, the Notes may be converted into shares of EuroSite Power's common stock at an initial conversion rate of 1,000 shares of common stock per $1,000 principal amount of Notes, subject to adjustment. At the scheduled maturity date, each of the Investors will have the following options: request payment of their principal amount and accrued interest in cash; extend the term of the Notes for an additional 3 years with an automatic decrease in interest rate to 3% per annum; or exchange the Notes for a new non-convertible note with a 3 year maturity and a 6% per annum interest rate; no accrued interest will be lost on such exchange.

                EuroSite Power initially concluded that the term-extending option mentioned above was an embedded derivative with de minimis value but has subsequently concluded that it is not considered a derivative under ASC 815-Derivatives and Hedging because the term extending feature is considered clearly and closely related to the Notes. Thus, this feature was no required to be bifurcated and no other initial accounting was required. The term-extending option has subsequently been eliminated pursuant to the note exchange agreements discussed below.

                The Noteholders Agreement provides for customary events of default by EuroSite Power, including failure to pay interest within ten days of becoming due, failure to pay principal when due, failure to comply provisions of the Notes or the Noteholders Agreement, subject to cure, and certain events of bankruptcy or insolvency.

                The holders of the Notes are entitled to the benefits of a registration rights agreement dated June 14, 2013 by and among EuroSite Power and the Noteholders named therein, or the Registration Rights Agreement. The Registration Rights Agreement provides for demand registration rights, such that upon the demand of 30% of the holders of Registrable Securities,

F-14

AMERICAN DG ENERGY INC.


as defined in the Registration Rights Agreement and subject to certain conditions (including that EuroSite Power is eligible to use a Form S-3 registration statement and that such holders anticipate an aggregate offering price, net of selling expenses, of at least $250,000), EuroSite Power will file a Form S-3 registration statement covering the Registrable Securities requested to be included in such registration, subject to adjustment.

On February 20, 2014, EuroSite Power accepted certain separate note exchange agreements, or the Note Exchange Agreements, from the holders of the Notes, pursuant to which EuroSite Power exchanged the Notes for like principal amounts of 4% Senior Convertible Notes Due 2017, or the New Notes, in an aggregate principal amount of $4,000,000. Accrued but unpaid interest on the Notes was treated as accrued interest under the New Notes. Included among the investors exchanging their Notes for New Notes were: the Company, in the amount of $1,100,000; Bruno Meier, a director of EuroSite Power, in the amount of $250,000; Prime World Inc., a company controlled by Joan Giacinti, one of the Company's directors, in the amount of $300,000; Charles T. Maxwell, Chairman of the Board of Directors of the Company, in the amount of $250,000; Nettlestone Enterprises Limited, a shareholder of both EuroSite Power and the Company, in the amount of $300,000; Perastra Management S.A., an investor in the Company and EuroSite Power, in the amount of $1,500,000; and Yves Micheli, an investor in EuroSite Power, in the amount of $300,000.

The effect of the Note Exchange agreement (a) extended the maturity date from June 14, 2015 to June 14, 2017, (b) adjusted the conversion price of the notes which changed from 1,000 shares of EuroSite Power's common stock for each $1,000 of principal converted to 1,667 shares of EuroSite Power’s common stock for each $1,000 of principal converted, and (c) eliminated the Holders’ options to extend the Notes. The Company analyzed the impact of the Note Exchange Agreement and determined that the Notes and the New Notes were substantially different and, as a result, EuroSite Power recognized a loss on extinguishment of $713,577 to recognize the excess of the fair value of the New Notes that were issued in the exchange over the carrying value of the Notes surrendered, of which, $180,400 related to the Company's holdings and was eliminated in consolidation. The New Notes were recorded at fair value as of the date of the exchange with the difference between the fair value of the debt of $4,656,000 and the carrying value of $4,000,000, or $656,000, being recorded as a premium. The portion of the $656,000 premium attributable to the Company's holdings, or $180,400, is eliminated in consolidation. The interest method of accounting is used to amortize the premium over the life of the New Notes. The fair value of the New Notes was determined using a binomial lattice model.  The following table provides quantitative information used in the fair value measurement, including the assumptions for the significant unobservable inputs used in the binomial lattice model valuation:

Notional amount

Significant increases (decreases) in the significant unobservable inputs used in the fair value measurement of the New Notes would result in a significantly higher (lower) fair value measurement.

Effective April 15, 2014 and April 24, 2014 EuroSite Power, entered into a subscription agreements with John N. Hatsopoulos, the chairman of the Company's Board of Directors, certain other investors and a principal owner of the Company for the sale of a $1,450,000, 4% Senior Convertible Note Due 2018. The 2014 Notes will mature in four years and will accrue interest at the rate of 4% per annum payable on a semi-annual basis. At the holder’s option, the 2014 Notes may be converted into shares of the EuroSite Power’s common stock at a conversion price of $0.60 per share, subject to adjustment in certain circumstances. The proceeds of the 2014 Notes will be used in connection with the development and installation of current and new energy systems, business development and for general corporate purposes.

On October 3, 2014, EuroSite Power, entered into convertible note amendment agreements, or the Note Amendment Agreements, with the Company, John N. Hatsopoulos and principal owner of the Company, as well as certain separate convertible note conversion agreements, or the Note Conversion Agreements, with certain other investors, which eliminated $3,050,000 of EuroSite Power's convertible notes.


F-15

AMERICAN DG ENERGY INC.


Among other things, the Note Amendment Agreements provided for the conversion, in full, of the principal amount of certain of the Notes and the 2014 Notes or collectively, the Converted Notes, in an aggregate principal amount of $3,050,000, pursuant to which the holders of such Converted Notes, or the Holders, agreed to convert, in full, the principal amount of the Converted Notes. In connection with the conversion, the Converted Notes were cancelled and the Holders were issued 6,100,000 shares of EuroSite Power’s common stock at a conversion price of $.50 per share, with any accrued but unpaid interest to be paid in cash.

The conversion price of $.50 per share was less than the $.60 per share that was contractually provided for on the convertible debentures. Accordingly, in accordance with ASC 470-20-40, this transaction was accounted for as an inducement conversion with the fair value of the incremental shares issued being recognized as an expense. On a consolidated basis after elimination of intercompany items, the expense recognized was $324,977.
    
The unamortized premium was $232,710 at December 31, 2014 and non-cash interest income related to amortization of the premium for the year-ended December 31, 2014 was $127,554, which was net with interest expense.

The Company guarantees (the “Guarantees”), the remaining Notes on a subordinated basis. Among other things, the Guarantees provide that, in the event of EuroSite Power's failure to pay principal or interest on a Note, the holder of such Note, on the terms and conditions set forth in the Notes, may proceed directly against the Company, as guarantor, to enforce the Guarantee. These securities were offered and sold to the investors in private placement transactions made in reliance upon exemptions from registration pursuant to Section 4(a)(2) under the Securities Act of 1933 and Rule 506 promulgated thereunder. The investors are accredited investors as defined in Rule 501 of Regulation D promulgated under the Securities Act of 1933.

 Stock-Based Compensation – EuroSite Power
 
In January 2011, EuroSite Power adopted the 2011 Stock Incentive Plan, or the Plan, under which their board of directors may grant up to 3,000,000 shares of incentive or non-qualified stock options and stock grants to key employees, directors, advisors and consultants of EuroSite Power. On June 13, 2011, their board of directors unanimously amended the Plan to increase the reserved shares of common stock issuable under the Plan from 3,000,000 to 4,500,000, or the Amended Plan.
 
Stock options vest based upon the terms within the individual option grants, usually over a four year period with an acceleration of the unvested portion of such options upon a liquidity event, as defined in EuroSite Power’s stock option agreement. The options are not transferable except by will or domestic relations order. The option price per share under the Amended Plan is not less than the fair value of the shares on the date of the grant. The number of securities remaining available for future issuance under the Amended Plan was 195,000 at December 31, 2014.

On March 20, 2013, EuroSite Power granted to a director options to purchase 100,000 shares of common stock, to a consultant options to purchase 50,000 shares of common stock, and to six employees options to purchase 88,000 shares of common stock. Those options have a vesting schedule of 4 years and expire in 10 years.

Note 6 – Warrant liability:
 

F-19

AMERICAN DG ENERGY INC.


In connection with a subscription agreement that the Company entered into on December 9, 2010, the Company issued warrants for the purchase of 500,000 shares of its common stock. The warrants have an exercise price of $3.25 and are exercisable for five years, commencing six months after the closing of the offering and expire on December 14, 2015.
 
The warrants contain both a right to obtain stock upon exercise, or a Call, and a right to settle the warrants for cash upon the occurrence of certain events, or a Put. Generally, the Put provisions allow the warrant holders liquidity protection; the right to receive cash equal to the value of the remaining unexercised portion of the warrants in certain situations where the holders would not have a means of readily selling the shares issuable upon exercise of the warrants (e.g., where there would no longer be a significant public market for the Company’s common stock). Specifically, the Put rights would be triggered upon the occurrence of a Fundamental Transaction as defined in the agreement. Pursuant to the agreement, in the case of a Fundamental Transaction the warrant holders would receive a cash settlement in an amount equal to the value of obtained by using the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg L.P. using (i) a price per share of Common Stock equal to the Volume-Weighted Average Price of the Common Stock for the Trading Day immediately preceding the date of consummation of the applicable Fundamental Transaction, (ii) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of the date of consummation of the applicable Fundamental Transaction and (iii) an expected volatility equal to the lesser of (1) the thirty (30) day volatility obtained from the “HVT” function on Bloomberg L.P. determined as of the end of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction or (2) 70%. These warrants are classified as liabilities pursuant to the FASB guidance contained in ASC 480. Changes in the fair value of the warrant liabilities are recorded in the accompanying statements of operations (see “Note 9 – Fair value measurements”).
 
Note 7 — Employee benefit plan:
 
The Company has a defined contribution retirement plan, or the Retirement Plan, which qualifies under Section 401(k) of the Internal Revenue Code, or the IRC. Under the Retirement Plan, employees meeting certain requirements may elect to contribute a percentage of their salary up to the maximum allowed by the IRC. The Company matches a variable amount based on participant contributions up to a maximum of 4.50% of each participant’s salary. The Company contributed $49,816 and $53,697 to the Retirement Plan for the years ended December 31, 2014 and 2013, respectively.
 
Note 8 — Related parties:
 
Eurosite Power, Tecogen, Ilios Inc., or Ilios are affiliated companies by virtue of common ownership.

The Company purchases the majority of its cogeneration units from Tecogen, an affiliate Company sharing similar ownership. In addition, Tecogen pays certain operating expenses, including benefits and payroll, on behalf of the Company and the Company leases office space from Tecogen. These costs were reimbursed by the Company. For year-ending December 31, 2014 and 2013, the Company bought equipment and maintenance services form Tecogen of $1,432,801 and $817,700, respectively.
  
In July 2012, the Company entered into a Facilities, Support Services and Business Agreement, or the Agreement, with Tecogen, to provide the Company with certain office and business support services for a period of one year, renewable annually by mutual agreement. Under the current amendment to the Agreement, Tecogen provides the Company with office space and utilities at a monthly rate of $6,495. On July 1, 2013 and November 12, 2013, the Company entered into an Amendments with Tecogen. The Amendments renews the term of the Facilities, Support Services and Business Agreement between the Company and Tecogen. The Amendments further clarifies that the total sales thresholds for volume discounts are to be met during a calendar year and that the Company's representation rights may be terminated by either the Company or Tecogen upon 60 days' notice, without cause. The Amendments state that in New England States the Company shall have the right to purchase Cogeneration products directly from Tecogen as described in the agreement so long as the Company intended use is it to retain long-term ownership of the Cogeneration product and utilize it for the production and sale of electricity and thermal energy. Tecogen will not sell its products to parties for which the intended use is to earn revenue from metered energy to third parties (i.e., ADG Energy “On-Site Utility” energy projects) other than the Company. In cases where the Company has the opportunity to sell Cogeneration products to an unaffiliated party in the New England States and where Tecogen has no other appointed representation in that specific region, the Company may buy/resell the Cogeneration product as specified under the terms of this agreement. If, however, Tecogen has appointed a local exclusive representative in that specific New England region, The Company will defer to the local representative for pricing and other specific details for working cooperatively. The Company has granted Tecogen sales representation rights on its On-Site Utility energy service in California.

In March 2013 the Company provided Tecogen, a related party, funds as prepayment for equipment purchases and services to be delivered or performed in 2013. The Company received a 6.0% per annum discount on deposit balances towards future purchases.

On October 22, 2009, the Company signed a five-year exclusive distribution agreement with Ilios Inc., or Ilios, a subsidiary of Tecogen. Under terms of the agreement, the Company has exclusive rights to incorporate Ilios’ ultra-high-efficiency heating products, such as a high efficiency water heater, in its energy systems throughout the European Union and New England. The Company also has non-exclusive rights to distribute Ilios’ product in the remaining parts of the United States and the world in cases where the Company retains ownership of the equipment for its On-Site Utility business.

On November 12, 2013, the Company entered into the First Amendment to the Sales Representative Agreement with Ilios. The Amendment allows Ilios to appoint sales representatives in the European Union (EU) in addition to the Company. For nations of the EU the company has the right under this agreement to purchase Ilios products directly from Ilios at a stipulated price so long as the Company intends use is to retain long-term ownership of the Ilios product and utilize it for the production and sale of thermal energy (i.e., ADG Energy/EuroSite Power “On-Site Utility” energy projects). Ilios will not sell its products to parties for which the intended use is to earn revenue from metered energy to third parties (i.e., ADG Energy/EuroSite Power “On-Site Utility” energy projects) other than the Company. In cases where the Company has the opportunity to sell Ilios product to an unaffiliated party in the EU and where Ilios has no other appointed representation in that specific region, the Company may buy/resell the Ilios product as specified under the terms of this contact. If, however, Ilios has appointed a local exclusive representative in that specific EU region, the Company will defer to the local representative for pricing and other specific details for working cooperatively.

On September 19, 2014, John Hatsopoulos loaned EuroSite Power $3,000,000 without interest pursuant to a promissory note (the "Loan"). The Loan matures upon a substantial capital raise or on September 19, 2019. Prepayment of principal may be made at any time without penalty. The proceeds of the Loan will be used in connection with the development and installation of current and new energy systems in the United Kingdom and Europe. On December 30, 2014, the EuroSite Power amended and restated the existing promissory note to provide for interest at a rate of 1.85%.

Note 9 — Fair value measurements:
 
The fair value topic of the FASB Accounting Standards Codification defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:
 
Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities. The Company currently does not have any Level 1 financial assets or liabilities.
 
Level 2 — Observable inputs other than quoted prices included in Level 1. Level 2 inputs include quoted prices for identical assets or liabilities in non-active markets, quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for substantially the full term of the asset or liability. The Company considers its convertible debentures a level 2 liability and believes that its carrying value approximates fair value.
 
Level 3 — Unobservable inputs reflecting management’s own assumptions about the input used in pricing the asset or liability.

As of December 31, 2014, the Company has classified the warrants with put and call rights as Level 3 (see “Note 6 – Warrant liability”). The Company estimated that the fair value of the warrants using a Black-Scholes option pricing model under various probability-weighted outcomes which take into consideration the protective, but limited, cash-settlement feature of the warrants. At issuance, the following average assumptions were assigned to the varying outcomes: expected volatility of 57.0%, risk free interest rate of 2.08%, expected life of five years and no dividends. The Company estimated that the fair value of the warrants at December 31, 2014 using this same model with the following average assumptions assigned to the varying outcomes: expected volatility of 91.4%, risk free interest rates of 0.02%, expected lives of 0.96 and no dividends. As of December 31, 2014, the financial liabilities held by the Company and measured at fair value on a recurring

               In connection with the Company’s asset impairment analysis (See “Note 2 - Summary of significant accounting policies” - Property, plant and equipment),  the Company utilized Level 3 category fair value measurements. Those measurements employed the use of discounted cash flow analysis to determine the fair value of certain energy systems. These analyses considered any conditional change which may impact the estimated future cash flows related to these assets resulting from changes in the level of demand for electricity and/or hot water at particular installations, finalization of start-up period customization at particular installations and/or price changes in electrical and natural gas rates, all of which impacted estimated future cash flows. The estimated expected cash flows were than discounted at a rate of 6% per annum.

As of December 31, 2014, the Company has federal and state loss carryforwards of approximately $24,683,000 and $19,865,000, respectively, which may be used to offset future federal and state taxable income, expiring at various dates through 2034. Included in these net operating losses is $1,353,000 of excess stock compensation deductions, related to the amount of tax deductions on restricted stock, in excess of book compensation expense. As of December 31, 2014, the Company also has foreign loss carryforwards of approximately $3,595,000 which may be used to offset future foreign taxable income. Management has determined that it is more likely than not that the Company will not recognize the benefits of the federal and state deferred tax assets and as a result has recorded a valuation allowance against the entire net deferred tax asset. If the Company should generate sustained future taxable income, against which these tax attributes may be recognized, some portion or all of the valuation allowance would be reversed. The valuation allowance increased by $1,316,000 during the year-ended December 31, 2014, due primarily to net operating losses generated, stock compensation and depreciation. The valuation allowance increased $1,511,000 during year-ended December 31, 2013, due primarily to net operating losses generated, stock compensation and depreciation.
 
The tax years 2003 through 2013 remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in the United States, as carry forward attributes generated in years past may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they are or will be used in a future period. The Company is currently not under examination by the Internal Revenue Service or any other jurisdiction for any tax years. The Company did not recognize any interest and penalties associated with unrecognized tax benefits in the accompanying consolidated financial statements.
The Company has no uncertain tax positions as of December 31, 2014.
In 2014, the Company recognized an United Kingdom energy tax incentive benefit of $649,000 for "Advanced Capital Allowances" (ECA), whereby the Company will receive a cash benefit that is an acceleration of tax relief on capital expenditures of co-generation equipment put into service at approved sites in the UK.

The Company's federal and state net operating losses could be limited to the extent that there are significant changes in ownership of the Company's stock. The company has not assessed the impacts of these limitations on its tax attributes.

Note 11 — Commitments and contingencies:
 
On July 1, 2013 the Company entered into an Amendment to the Facilities, Support Services and Business Agreement, or the Amendment, with Tecogen. The Amendment renews the term of the Facilities, Support Services and Business Agreement between the Company and Tecogen for a one year period, beginning on July 1, 2013. The Amendment

also increases the space provided to the Company by Tecogen from approximately 3,071 square feet to 3,282 square feet and from six offices to nine offices. Under the Amendment, the amount that the Company will pay Tecogen for the space and services that Tecogen provides under the Agreement increased to $6,495 per month.
