AMERICAN DG ENERGY INC.

Notes to Interim Unaudited Condensed Consolidated Financial Statements for the period ending June 30, 2013

Note 1 – Description of business and summary of significant accounting policies:

Description of business

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”.

Basis of Presentation

The unaudited condensed consolidated financial statements, or the Unaudited Financial Statements, presented herein have been prepared by the Company, without audit, and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the interim periods presented. The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, for reporting in this Quarterly Report on Form 10-Q, or the Quarterly Report. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. It is suggested that the Unaudited Financial Statements be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual report on Form 10-K for the year ended December 31, 2012, or the Annual report, filed with the SEC. The Company’s operating results for the six month periods ended June 30, 2013, may not be indicative of the results expected for any succeeding interim periods or for the entire year ending December 31, 2013.     

The accompanying consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary American DG Energy, its 51.0% joint venture, American DG New York, LLC, or ADGNY, and its 79.3% owned subsidiary EuroSite Power Inc., or EuroSite Power.

The Company owns 51.0% of ADGNY, after elimination of all material intercompany accounts, transactions and profits. The interest in underlying energy system projects in the joint venture varies 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 and profitability of the underlying energy projects. The economic ownership of the energy projects 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, Peter Westerhoff, each quarter. On the Company’s consolidated balance sheets, 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 a 62.8% economic interest in ADGNY as of June 30, 2013.

In July 2010 the Company invested $45,000 in exchange for 45 million shares of EuroSite Power, a newly established corporation. The investment gave the Company a controlling financial interest in EuroSite Power, whose business focus is to introduce the On-Site Utility solution into the European market. Also in July 2010, Nettlestone Enterprises Limited, invested $5,000 in exchange for 5 million shares in EuroSite Power. During the year ended December 31, 2012, EuroSite Power raised approximately $1,250,000 in private placements by selling 1,250,000 shares of EuroSite Power common stock to accredited investors at $1.00 per share. As of June 30, 2013 the Company owns an 79.3% interest in EuroSite Power and has consolidated EuroSite Power into its financial statements in accordance with GAAP.

On February 10, 2012, EuroSite Power announced that its Board of Directors declared a stock dividend of 10.0% per share on the outstanding shares of EuroSite Power common stock. The dividend was payable on March 12, 2012 to common stockholders of record at the close of business on February 24, 2012. EuroSite Power has retroactively reflected this dividend to its December 31, 2012 financial statements. The Company has rejected the receipt of the dividend on the EuroSite Power shares it currently holds.

AMERICAN DG ENERGY INC.

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 has experienced total net losses since inception of approximately $26.7 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 12 months; however, as the Company continues to grow its business by adding more energy systems, the cash requirements will increase. Beyond June 30, 2014, 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 2012, the Company raised $3,535,038, net of issuance costs, from private placements of common stock, $7,500 from issuance of warrants and $200,923 from exercise of stock options. If the Company is unable to raise additional capital in 2013 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 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.

As a by-product of the energy business, in some cases, the customer may choose to have the Company construct the system for them 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.

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 had no such arrangements at June 30, 2013 and 2012, respectively.

Occasionally, 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

8

AMERICAN DG ENERGY INC.

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 had no such arrangements at June 30, 2013 and 2012, respectively.

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. At June 30, 2013 and 2012, the revenue recognized from demand response activity was $12,287 and $51,784, respectively. The Company treats demand response payments as an operating activity in the statements of cash flows.

Other revenue represents various types of ancillary activities for which the Company expects to engage in from time to time such as the sale of equipment, construction work, engineering work and feasibility studies.

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 of 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 June 30, 2013, the Company had a balance of $6,728,359 in cash and cash equivalents that exceeded the Federal Deposit Insurance Corporation limit of $250,000 per institution.

Accounts Receivable

The Company maintains receivable balances primarily with customers located throughout New York and New Jersey. 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 June 30, 2013 and December 31, 2012, the allowance for doubtful accounts was $114,000 and $54,000, 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 June 30, 2013 and December 31, 2012, there were no reserves or write-downs recorded against inventory.

Supply Concentrations

The majority of the Company’s cogeneration unit purchases as of June 30, 2013 and December 31, 2012, 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. 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 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.

9

AMERICAN DG ENERGY INC.

The Company evaluates the recoverability of its long-lived assets by comparing the 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 lesser of the economic life of the asset or the term of the underlying contract with the customer, typically 12 to 15 years. The Company reviews for impairment 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. If impairment is indicated, the asset is written down to its estimated fair value based on a discounted cash flow analysis.

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. During the period ending June 30, 2013 and 2012, the amount of rebates applied to the cost of construction was $146,318 and $260,701, 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 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 6 – Stock based compensation” for a summary of the restricted stock and stock option activity under the Company’s stock-based employee compensation plan for the periods ended June 30, 2013 and 2012, respectively.

Loss per Common Share

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.

Other Comprehensive Net Loss

The comprehensive net loss for the period ended June 30, 2013 and December 31, 2012, does not differ from the reported 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% 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.

The tax years 2003 through 2005 and 2010 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 12 months of the reporting date.

Reclassifications

Certain prior period balances have been reclassified to conform with current period presentation.

Impact of New Accounting Pronouncements

Management does not believe that any recently issued accounting pronouncements or issued but yet effective

accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Note 2 – Loss per common share:

The Company computes basic loss per share by dividing net loss for the period by the weighted-average number of shares of common stock outstanding during the period. The Company computes its diluted earnings per common share using the treasury stock method. For purposes of calculating diluted loss 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/conversion price is less than the average market price of the common stock for the period. All shares issuable for both periods were anti-dilutive because of the reported net loss. Basic and diluted loss per share for the three months and six months ended June 30, 2013 and 2012 respectively was as follows:

	Three Months Ended						Six Months Ended

Note 3 – Convertible debentures:

On May 23, 2011, the Company issued $12,500,000 aggregate principal amount of debentures to a European investor and to John N. Hatsopoulos, the Company’s Chief Executive Officer. The debentures mature on May 25, 2018 and accrue interest at the rate of 6% 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 proceeds of the debentures will be used in connection with the development and installation of current and new energy systems, business development and for general corporate purposes. 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 European investor. The debentures mature on May 25, 2018 and accrue interest at the rate of 6% 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 proceeds of the debentures will be used in connection with the development and installation of current and new energy systems, business development and for general corporate purposes.

In March 2012, the debenture holders amended the terms on the debentures with respect to the interest payment and agreed to receive their interest payment 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 the agreement, for the May semi-annual interest payment, the Company used the April average daily closing price of the common stock in order to determine the conversion price. All other terms and conditions, including interest rate and maturity date remained the same.

On May 25, 2012, the total interest due to the debenture holders was $559,000 and in connection with the amendment the Company issued to the debenture holders 251,917 shares of common stock at $2.22 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 $153,921 of non-cash interest expense, which was the difference between the average stock price and the fair market value on May 25, 2012.

In September 2012, the debenture holders amended the terms on the debentures with respect to the interest payment and agreed to receive their interest payment 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 the agreement, the Company will use the average daily closing price of the Common Stock 10 business days before the interest payment date (May 25^th and November 25^th) in order to determine the conversion price. All other terms and conditions, including interest rate and maturity date remain the same.

On November 25, 2012, the total interest due to the debenture holders was $582,000 and in connection with the amendment the Company issued to the debenture holders 249,787 shares of common stock at $2.33 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 $57,451 of non-cash interest expense, which was the difference between the average stock price and the fair market value on November 25, 2012.

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 interest payments 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 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.

At June 30, 2013, the Company had a balance of $20,000 due to John N. Hatsopoulos related to interest payable on his outstanding convertible debentures.

On June 14, 2013, EuroSite Power entered into subscription agreements with certain investors, including American DG Energy for a private placement of an aggregate principal amount of $4,000,000 of 4.0% Senior Unsecured Convertible Notes due on June 14, 2015, or the Notes. In connection with the private placement, American DG Energy exchanged a promissory note in the aggregate principal amount of $1,100,000, originally issued on February 26, 2013, or the Old Note, for a like principal amount of the Notes and cash paid for any accrued but unpaid interest on the Old Note. The Company guarantees, or the Guarantees, the 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 Noteholders Agreement, may proceed directly against the Company, as guarantor, to enforce the Guarantee without first proceeding against EuroSite Power.

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 4.0% 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 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 3.0% per annum; or exchange the Notes for a new non-convertible note with a 3 year maturity and a 6.0% per annum interest rate; no accrued interest will be lost on such exchange. The Company and EuroSite Power have evaluated the term-extending option and have determined that the extension option on the Notes represents a derivative under ASC 815-15-25-44 however, they have concluded that its value at inception and at June 30, 2013 was de minimis based on the current rising interest rate environment; the improving U.S. economy and the potential end of Federal Reserve bond purchases; and current market yields of convertible debentures with maturities similar to ours.

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 30.0% of the holders of Registrable Securities, 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, and use its commercially reasonable efforts to cause such registration statement to become effective. For additional disclosure see the Company's filings with the SEC.

In January 2011, the Company’s subsidiary EuroSite Power, adopted the 2011 Stock Incentive Plan, or the Stock Plan. The aggregate number of shares of common stock which may be issued pursuant to this Stock Plan is 3,000,000 shares.

On June 13, 2011, the board unanimously amended the Stock Plan, subject to shareholder approval, to increase the reserved shares of common stock issuable under the Stock 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 two- or ten-year period with an acceleration of the unvested portion of such options upon a liquidity event, as defined in the Company’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 market value of the shares on the date of the grant. At June 30, 2013 there were 2,310,000 unvested stock options outstanding of EuroSite Power with a vesting schedule of 25% per year and expiration in 10 years.

Note 7 – Warrant liability:

On December 9, 2010, the Company entered into subscription agreements with selected investors for the purchase of units consisting, in the aggregate, of 500,000 shares of its common stock and warrants to purchase 500,000 shares of its common stock. The subscription agreements provided for the purchase of the units at a purchase price of $2.50 per unit, and the warrants had an exercise price of $3.25 per share of common stock and are exercisable for 5 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 consolidated statements of operations (see “Note 10 – Fair value measurements”).

Note 9 – Commitments and contingencies:

16

AMERICAN DG ENERGY INC.

In July 2011, the Company put on notice an On-Site Utility energy customer, River Point Towers Cooperative Inc., or RPT, over services provided pursuant to an Equipment Lease Agreement between the Company and RPT due to breach of contract for non-payment of receivables. The Company notified RPT’s management that the non-payment of receivables violated the terms of the agreement and that termination charges would apply. The Company stopped providing energy services at that site in August 2011. In October 2011, the Company filed a lawsuit at the United States District Court for the Southern District of New York to collect the receivables it was due and in May 2012, the Company and RPT settled their claims without admission of any liability. As a result of this settlement, the equipment was removed from the site at a cost of $100,500 and the movement of the equipment resulted in an additional charge of $237,968 (included in depreciation expense) in the second quarter of 2012.

Note 10 – 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 currently does not have any Level 2 financial assets or liabilities.

Level 3 — Unobservable inputs reflecting management’s own assumptions about the input used in pricing the asset or liability. As of June 30, 2013, the Company has classified 500,000 warrants with an exercise price of $3.25 per share that contain put and call rights as Level 3 (see “Note 7 – Warrant liability”). The Company records the fair value of the warrant liability on a recurring basis and estimates 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 60.7%, 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 June 30, 2013, using this same model with the following average assumptions assigned to the varying outcomes: expected volatility of 56.0%, risk free interest rates of 1.41%, expected lives of 2.46 years and no dividends. The fair value measurement of the warrant liability is particularly sensitive to the price and volatility of the Company's common stock. As of June 30, 2013, the financial liabilities held by the Company and measured at fair value on a recurring basis (which consist solely of the warrant liability) were $70,448.

The following table summarizes the activity for the period: 

	Warrant Liabilities
Fair value at December 31, 2012	$	389,454
Fair value adjustment at 6/30/2013	319,006
Fair value at 6/30/2013	$	70,448

The Company’s other financial instruments include cash and cash equivalents, 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 carrying value of the convertible debentures on the balance sheet at June 30, 2013 approximates fair value as the terms (Level 2 inputs) approximate those currently available for similar instruments.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-looking statements are made throughout this Management’s Discussion and Analysis of Financial Condition and Results of Operations. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects,” “seeks,” “estimates” and similar expressions are intended to identify forward-looking statements. Such forward-looking statements include, among other things, statements regarding our current and future cash requirements, our expectations regarding suppliers of cogeneration units, and statements regarding potential financing activities in the future. While the Company may elect to update forward-looking statements in the future, it specifically disclaims any obligation to do so, even if the Company’s estimates change and readers should not rely on those forward-looking statements as representing the Company’s views as of any date subsequent to the date of the filing of this Quarterly Report. There are a number of important factors that could cause the actual results of the Company to differ materially from those indicated by such forward-looking statements, including those detailed under the heading “Risk Factors” in this Quarterly Report.

The Company distributes and operates on-site cogeneration systems that produce both electricity and heat. The Company’s primary business 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. The Company calls this business the American DG Energy “On-Site Utility”.

Second Quarter 2013 Compared to Second Quarter 2012.

Revenues

Revenues in the second quarter of 2013 were $1,769,783 compared to $1,192,957 for the same period in 2012, an increase of $576,826 or 48.4%. The increase in revenues was primarily due to increase in output of our energy systems during the second quarter of 2013 compared to the same period in 2012, offset by a decrease in our turnkey and other revenue. Our On-Site Utility energy revenue in the second quarter of 2013 was $1,732,497 compared to $1,136,265 for the same period in 2012, an increase of $596,232 or 48.4%. Our turnkey and other revenue in the second quarter of 2013 decreased to $37,286 compared to $56,692 for the same period in 2012, a decrease of $19,406 or 34.2%. During the second quarter of 2013 the Company performed billable services and recorded revenue from the maintenance of energy systems and commissions from the sale of equipment. The revenue from our turnkey projects can vary substantially per period. While the Company accepts turnkey installation projects, they are not considered our core business.

During the second quarter of 2013, the Company operated 104 energy systems, at 62 locations representing 6,863 kW of installed electricity plus thermal energy, compared to 89 energy systems at 48 locations, representing 6,202 kW of installed electricity plus thermal energy for the same period in 2012. The revenue per customer on a monthly basis is based on the sum of the amount of energy produced by the Company’s energy systems and the published price of energy (electricity, natural gas or oil) from its customers’ local energy utility that month, less the discounts the Company provides its customers. The Company’s revenues commence as new energy systems become operational.

Cost of Sales

Cost of sales, including depreciation, in the second quarter of 2013 were $1,466,104 compared to $1,229,634 for the same period in 2012, an increase of $236,470 or 19.2%. Included in the cost of sales was depreciation expense of $329,302 in the second quarter of 2013, compared to $534,888 for the same period in 2012. The depreciation in 2012 included $237,968 of additional depreciation expense related to River Point Towers Cooperative Inc. The cost of fuel, maintenance and installation was $1,136,802 in the second quarter of 2013, compared to $694,746 for the same period in 2012, an increase of $442,056 or 63.6% due to the increase in the cost of sales at our EuroSite Power subsidiary.

During the second quarter of 2013, our gross margins were 17.2% compared to negative 3.1% for the same period in 2012, primarily due to the increase in our revenue base. Our On-Site Utility energy margins excluding depreciation were at 34.2% in the second quarter of 2013, compared to 39.2% for the same period in 2012.

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 the second quarter of 2013 were $844,418 compared to $677,371 for the same period in 2012, an increase of $167,047 or 24.7%. The increase was due to the exchange rate difference and administrative expenses at our EuroSite Power subsidiary.

19

AMERICAN DG ENERGY INC.

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 the second quarter of 2013 were $277,388 compared to $624,159 for the same period in 2012, a decrease of $346,771 or 55.6%. The decrease was primarily due to the reduction in advertising, equipment removal coats and other selling expenses.

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 the second quarter of 2013 were $267,588 compared to $300,265 for the same period in 2012, a decrease of $32,677. The decrease was due to reduction in engineering consulting services.

Loss from Operations

The loss from operations in the second quarter of 2013 was $1,085,715 compared to loss $1,638,472 for the same period in 2012, a decrease of $552,757 or 33.7%. The decrease in the operating loss was due to better cost controls at the parent and subsidiary companies and due to lower professional services fees. Our non-cash compensation expense related to outstanding restricted stock and option awards to our employees was $146,672 in the second quarter of 2013, compared to $189,130 for the same period in 2012.

Interest and other income was $42,144 in the second quarter of 2013 compared to $13,682 for the same period in 2012, an increase of $28,462. The increase was due to higher yields on our invested funds. Interest expense was $260,537 in the second quarter of 2013 compared to $447,477 for the same period in 2012, a decrease of $186,940 due to interest payable in common stock on our convertible debentures issued in May 2011. In the second quarter of 2013, the change in fair value of warrant liability resulted in a gain of $208,187 compared to a loss of $44,602 for the same period in 2012 (see “Note 7 – Warrant liability”).

Benefit (Provision) for Income Taxes

Our provision for state income taxes in the second quarter of 2013 was $7,055 compared to a benefit of $7,140 for the same period in 2012.

Noncontrolling Interest

The noncontrolling interest share in the profits or losses in ADGNY and EuroSite Power was a loss of $54,484 in the second quarter of 2013 compared to a loss of $60,764 for the same period in 2012. The change was due to expenses in the EuroSite Power subsidiary, offset by revenue in the joint venture. 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. The special dividend will be payable 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 will issue to its stockholders approximately 4,880,720 shares of EuroSite Power common stock that it owns and, as a result, its noncontrolling interest ownership percentage in EuroSite Power is expected to be 29.3%.

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 interest payments 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 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.

On June 14, 2013, EuroSite Power entered into subscription agreements with certain investors, including American DG Energy for a private placement of an aggregate principal amount of $4,000,000 of 4.0% Senior Unsecured Convertible Notes due on June 14, 2015, or the Notes. In connection with the private placement, American DG Energy exchanged a promissory note in the aggregate principal amount of $1,100,000, originally issued on February 26, 2013, or the Old Note, for a like principal amount of the Notes and cash paid for any accrued but unpaid interest on the Old Note. The Company guarantees, or the Guarantees, the 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 Noteholders Agreement, may proceed directly against the Company, as guarantor, to enforce the Guarantee without first proceeding against EuroSite Power. See "Note 3 - Convertible debentures".

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 cost. Therefore the Company is capital intensive. 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

23

AMERICAN DG ENERGY INC.

systems, the cash requirements will increase. Beyond June 30, 2014, 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 may be negatively affected. In such case, the Company may need to suspend any new installation of energy systems and significantly reduce its operating costs until market conditions improve.

Significant Accounting Policies and Critical Estimates

The Company’s significant accounting policies are discussed in the Notes to the Consolidated Financial Statements above and are those that are incorporated in the Annual Report. The accounting policies and estimates that can have a significant impact upon the operating results, financial position and footnote disclosures of the Company are described in the above notes and the Financial Review in the Company’s Annual Report.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, including any outstanding derivative financial statements, off-balance sheet guarantees, interest rate swap transactions or foreign currency contracts. We do not engage in trading activities involving non-exchange traded contracts.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Not applicable

Item 4. Controls and Procedures

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 Chief Executive Officer and Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures as of June 30, 2013, or the Evaluation Date, have concluded that as of the Evaluation Date, our disclosure controls and procedures were not effective due to material weaknesses in financial reporting relating to lack of personnel with a sufficient level of accounting knowledge and a small number of employees dealing with general controls over information technology. At the present time, our management has decided that, considering the employees involved and the control procedures in place, there are risks associated with the above, but the potential benefits of adding additional employees to mitigate these weaknesses do not justify the expenses associated with such increases. Management will continue to evaluate the above weaknesses, and as the Company grows and resources become available, the Company plans to take the necessary steps in the future to remediate the weaknesses.

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 Securities Exchange Act of 1934 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.

Changes in Internal Control over Financial Reporting:

In connection with the evaluation referred to in the foregoing paragraph, we have made changes in our internal controls over financial reporting. We hired a consultant to review existing controls and review recent updates and changes to the Company’s documentation to ensure that any process or control changes are properly identified and documented, including updating the Company’s existing risk matrix. The engagement included the creation of testing plans based upon the current state of processes and key controls and the identification of areas for process improvements and documentation updates. The Company has already implemented many of the recommended processes.
