Item 3.03 Material Modifications to Rights of Security Holders.

The disclosure set forth under Item 5.03 below is incorporated herein by reference.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On July 18, 2012, Satcon Technology Corporation (the “Company”) filed a Certificate of Amendment (the “Certificate of Amendment”) to its Certificate of Incorporation, as amended to date, with the Secretary of State of the State of Delaware to effect a 1-for-8 reverse stock split (the “Reverse Split”) of the Company’s outstanding common stock, par value $0.01 per share (the “Common Stock”), and proportionately reduced the number of authorized shares of Common Stock to 37,500,000.  The Company’s Board of Directors authorized the Reverse Split in accordance with stockholder approval granted at the Annual Meeting of Stockholders held on June 20, 2012.  Pursuant to the filing of the Certificate of Amendment, the Reverse Split became effective at 12:01 a.m., Eastern Time, on July 19, 2012 (the “Effective Time”).

At the Effective Time, each eight shares of Common Stock issued and outstanding immediately prior to the Effective Time were automatically combined into one validly issued, fully paid and non-assessable share of Common Stock without any further action by the Company or the holders thereof.  No cash or fractional shares will be issued in connection with the Reverse Split, and instead the Company will round up to the next whole share in lieu of issuing factional shares that would have been issued in the Reverse Split.  The Reverse Split reduced the number of outstanding shares of Common Stock from approximately 144.2 million to approximately 18.0 million.

American Stock Transfer & Trust Company, LLC is the exchange agent for the Reverse Split.  Stockholders who hold their shares in brokerage accounts or “street name” are not required to take any action to effect the exchange of their shares.  Stockholders who hold stock certificates will receive instructions from the transfer agent regarding the process for exchanging their shares shortly after the Effective Time.

Item 8.01 Other Events.

For the 20 trading days immediately following the Reverse Split, the Common Stock will trade on The NASDAQ Capital Market under the trading symbol “SATCD” as an interim symbol to denote the effectiveness of the Reverse Split.  After this 20 trading day period, the Common Stock will resume trading under the symbol “SATC.”  In addition, the split-adjusted common stock will trade under a new CUSIP number, 803893 403.

On July 19, 2012, the Company issued a press release announcing the Reverse Split.  A copy of the press release is attached as Exhibit 99.1 and is incorporated herein by reference.
