Item 3.02                                           Unregistered Sales of Equity Securities.

On December 15, 2014 (the “Closing Date”), STR Holdings, Inc. (the “Company”), completed its previously announced sale of 27,632,130 shares (the “Purchased Shares”) of its authorized but unissued common stock, par value $0.01 per share (the “Common Stock”), to Zhen Fa New Energy (U.S.) Co., Ltd. (the “Purchaser”), a Nevada corporation and indirect subsidiary of Zhenfa Energy Group Co., Ltd., a Chinese limited liability company (“Zhenfa”), for an aggregate purchase price of approximately $21.7 million (the “Share Issuance”), pursuant to a Stock Purchase Agreement, dated as of August 11, 2014 (the “Purchase Agreement”), by and between the Company and the Purchaser. The issuance and sale of the Purchased Shares was a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended.

In connection with the closing of the Share Issuance (the “Closing”), the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the Purchaser that will, among other things, require the Company to register the Purchased Shares upon the request of the Purchaser or certain transferees of the Purchaser.  Pursuant to the terms of the Registration Rights Agreement, these registration rights will not become effective until one year after the Closing Date and the costs incurred in connection with such registrations will be borne by the Company.

The foregoing description of the Share Issuance, the Purchase Agreement and the Registration Rights Agreement is not complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which was attached as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on August 12, 2014, and is incorporated herein by reference, and the Registration Rights Agreement, which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 5.01                                           Changes in Control of Registrant.

As more fully described under Item 3.02 of this Current Report on Form 8-K, which disclosures are incorporated herein by reference, following the Share Issuance, the Purchaser currently owns approximately 51% of the Company’s outstanding Common Stock.  Therefore, the Share Issuance resulted in a change in control of the Company.

Pursuant to the Purchase Agreement, two members of the Board of Directors of the Company (the “Board”) resigned effective as of the Closing and the Board was expanded from five members to seven members. Four new directors, who were each nominated by the Purchaser, were appointed to the Board effective as of the Closing, constituting a majority of the Board. Reference is made to Item 5.02 of this Current Report on Form 8-K regarding the resignation of certain directors and the appointment of new officers and directors. The disclosure contained in Item 5.02 is hereby incorporated by reference in its entirety into this Item 5.01.

Item 5.02                                           Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Effective as of the Closing, each of Robert M. Chiste and Dennis L. Jilot, who served as members of the Board prior to the Closing, resigned from their directorships and any committee of which they were a member. These resignations were as a result of the Closing and pursuant to the terms of the Purchase Agreement and were not

a result of any disagreements with the Company on any matter relating to the Company’s operations, policies or practices.

Effective as of the Closing, and pursuant to the terms of the Purchase Agreement, the Company appointed Andrew Africk, Eugene Cha, Qu Chao and Xin (Cindy) Lin to the Board. Each of Messrs. Africk, Cha, Chao and Ms. Lin were nominated by the Purchaser (each, a “Purchaser Director”). Messrs. Africk and Cha are independent directors (in accordance with the rules of the New York Stock Exchange) and have each been named to the Audit Committee and the Nominating and Corporate Governance Committee of the Board. Mr. Africk has also been named to the Compensation Committee of the Board.

Nevertheless, as a result of his independence from the Purchaser, Mr. Africk is one of two independent directors nominated by the Purchaser. Mr. Africk was selected to serve on our Board in light of his significant experience in making and managing private equity investments and extensive experience in financing, analyzing and investing in public and private companies, as well as his experience as a director of public and private companies, including service on audit, compensation and nominating committees.
