Section 1— Registrant’s Business and Operations
Item 1.01 Entry into a Material Definitive Agreement

On September 29, 2016, Active Power, Inc., a Delaware corporation (the “Company”), Langley Holdings plc, a United Kingdom public limited company (“Langley”), and Piller USA, Inc., a Delaware corporation and a wholly owned subsidiary of Langley (“Buyer”) entered into an Asset Purchase Agreement (the “Purchase Agreement”).
 
The Purchase Agreement provides, among other things and subject to the terms and conditions set forth therein, that Buyer will purchase from the Company substantially all of the assets and operations of the Company, for a nominal purchase price plus the assumption of all indebtedness, including bank debt, liabilities and customer, employee and purchase commitments going forward (the “Acquisition”).
 
The Board of Directors of the Company (the “Board”) has unanimously approved the Purchase Agreement and the transactions contemplated thereby. The closing of the Acquisition is subject to the approval of the Acquisition by the affirmative vote of holders of at a majority of all outstanding shares of common stock of the Company (the “Company Stockholder Approval”). The closing of the Acquisition is also subject to various customary conditions, including the absence of any governmental order prohibiting the consummation of the transactions contemplated by the Purchase Agreement, the accuracy of the representations and warranties contained in the Purchase Agreement and compliance with the covenants and agreements in the Purchase Agreement.
 
The Company has made customary representations, warranties and covenants in the Purchase Agreement, including, among others, covenants (1) to conduct its business in the ordinary course of business during the period between the execution of the Purchase Agreement and the closing of the Acquisition, (2) not to engage in specified types of transactions during this period unless agreed to in writing by Buyer, and (3) to convene and hold a meeting of its stockholders for the purpose of obtaining the Company Stockholder Approval.
 
The Purchase Agreement contains certain termination rights, including the right of either party to terminate the Purchase Agreement if the closing of the Acquisition has not taken place on or before December 31, 2016.
 
The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by the full text of the Purchase Agreement, a copy of which is attached hereto as Exhibit 2.1  and is incorporated into this report by reference in its entirety. The Purchase Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company or Langley. In particular, the assertions embodied in the representations and warranties contained in the Purchase Agreement are qualified by information in a confidential Seller Disclosure Schedule provided by the Company to Langley and Buyer in connection with the signing of the Purchase Agreement. This confidential Seller Disclosure Schedule contains information that modifies, qualifies and creates exceptions to the representations and warranties of the Company set forth in the Purchase Agreement. Moreover, certain representations and warranties in the Purchase Agreement were used for the purposes of allocating risk between the Company and Langley rather than establishing matters of fact. Accordingly, the representations and warranties in the Purchase Agreement should not be relied on as characterization of the actual state of facts about the Company, Langley or Buyer.

Forward-Looking Statements

 This current report contains certain “forward-looking” statements as that term is defined by Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Forward-looking statements may be typically identified by such words as “may,” “will,” “should,” “expect,” “anticipate,” “plan,” “likely,” “believe,” “estimate,” “project,” “intend” and other similar expressions, among others. These forward-looking statements are subject to known and unknown risks and uncertainties that could cause our actual results to differ materially from the expectations expressed in the forward-looking statements. Although we believe that the expectations reflected in our forward-looking statements are reasonable, any or all of our forward-looking statements may prove to be incorrect. Consequently, no forward-looking statements may be guaranteed and there can be no assurance that the actual results or developments anticipated by such forward-looking statements will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, the Company or its business or operations. Factors that could cause our actual results to differ from those projected or contemplated in any such forward-looking statements include, but are not limited to, the following factors: (1) the risk that the conditions to the closing of the proposed transaction are not satisfied (including a failure of the stockholders of the Company to approve, on a timely basis or otherwise, the proposed transaction); (2) litigation relating to the proposed transaction; (3) uncertainties as to the timing of the consummation of the proposed transaction and the ability of each of Langley and the Company to consummate the proposed transaction; (4) risks that the proposed transaction disrupts the current plans and operations of the Company; (5) competitive responses to the proposed transaction; (6) unexpected costs, charges or expenses resulting from the proposed transaction; (7) potential adverse reactions or changes to business relationships resulting from the announcement of the proposed transaction; and (8) legislative, regulatory and economic developments. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors included in the Company’s most recent Annual Report on Form 10-K for the year ended December 31, 2015, and our more recent reports filed with the SEC. You should not rely upon forward-looking statements as predictions of future events. The forward-looking statements speak only as of the date of the communication in which they are contained. The Company can give no assurance that the conditions to the proposed transaction will be satisfied. Except as required by applicable law, the Company undertakes no obligation to revise or update any forward-looking statement, or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.

The Seller is not required to give any notice to, make any filing with, or obtain any authorization, consent, or approval of any Person, including, without limitation, any government or governmental agency, in order for the parties to consummate the transactions contemplated in this Agreement or any of the Other Seller Documents, except for (i) the Requisite Stockholder Approval, (ii) the filing with the SEC of such reports under the Securities Exchange Act as may be

4

required in connection with this Agreement and the transactions contemplated by this Agreement, (iii) any filings required under the rules of NASDAQ, and (vii) such other consents, approvals, authorizations or permits, filings or notifications, the failure of which to have, make or obtain, as applicable, would not constitute, individually or in the aggregate, a Material Adverse Effect.

Each such lease under which the lessor is an officer, director or stockholder of the Seller, or an Affiliate of any such person, will be so identified to the Buyer in writing and is on terms not less favorable to the Seller than if made with an independent third party.
2.6    Subsidiaries. Section 2.6 of the Seller Disclosure Schedule sets forth a list of all the subsidiaries of the Seller (the “Subsidiaries”). As of the Execution Date, the Seller does not, directly or indirectly, own any capital stock or other equity interest in any Person other than the Subsidiaries.

Active Power Enters into Asset Purchase Agreement
with Langley Holdings PLC

Transaction Unites Flywheel UPS Specialist with
World’s Largest Rotary UPS Manufacturer

AUSTIN, Texas (Sept. 30, 2016) – Active Power (NASDAQ: ACPW) (“Company”), a manufacturer of flywheel energy storage products and modular infrastructure solutions (MIS), today announced that it has signed an Asset Purchase Agreement (APA) with Langley Holdings PLC (“Langley”). Under the terms of the APA, Langley will acquire substantially all assets and operations of Active Power, including the Active Power name, through their Piller USA Inc. subsidiary for a nominal purchase price, plus the assumption of all debt, liabilities, customer, employee and purchase commitments going forward. Closing is subject to customary conditions and to the approval of the stockholders of Active Power. Closing is expected to occur in the fourth quarter of 2016.

Langley is a diverse, privately owned engineering and industrial group based in the United Kingdom with principal operating divisions located in Germany and France and more than 80 subsidiaries worldwide. The group was founded by the current Chairman, Tony Langley, in 1975 and had revenues of $1.1 billion in 2015. In 2004, Langley acquired Piller Group GmbH, a world leader in power protection technology and rotary UPS systems. Langley’s mid-year 2016 financial statements can be viewed here.

“The acquisition of the assets of Active Power is consistent with Langley’s strategy and business model,” said Board member, Bernard J. Langley. “The addition of Active Power’s differentiated flywheel UPS technology to Piller’s power protection portfolio will further strengthen its position in the market, creating more compelling alternatives to traditional UPS offerings for mission critical applications. We plan to maintain Active Power’s manufacturing operations in Austin, further expanding our operating footprint in the United States with this acquisition.”

“We are delighted to enter into this agreement with Langley as we believe it equitably addresses the present circumstances facing Active Power with an optimized outcome,” said Mark A. Ascolese, the Company’s President and CEO. “The current capital market environment is very challenging, making it difficult to raise capital through traditional equity financing to support our current operations. Langley is a proven, long-term investor and this deal enables us to avoid a costly liquidation process or further funding operations given our diminished cash balance. We believe it is the best alternative available for the benefit of our stockholders, customers, employees and vendors.”

After the Closing, under the APA the Company will transition its business model to monetize non-core intellectual property assets not purchased by Langley, and to acquire profitable businesses. The Company is in active negotiations with several parties to raise additional capital to support this business strategy.

“The Agreement with Langley is an important step towards positioning the Company for the future,” Ascolese continued. “Our business plan is to leverage the assets not sold to Langley and to acquire and operate businesses that will generate profit and positive cash flows, thereby creating enterprise value and utilizing our net operating loss carry forward and other tax benefits 1 . We believe this strategy is in the best interest of all our stakeholders and will result in higher long term stockholder value than the other alternatives available to us.”
