Section 2 - Financial Information

Item 2.01 Completion of Acquisition or Disposition of Assets.

On April 18, 2013, we closed on our share purchase agreement to acquire 100% of the equity interest in Orbital Gas Systems Limited, a company organized under the laws of England and Wales (“Orbital”), from Orbital’s sole shareholder, Andrew Marks Clews. The purchase price for the acquisition of Orbital was £17,000,000 British pounds sterling (“£”), subject to purchase price adjustments, 100% of the purchase price was paid in cash. To secure indemnification obligations, 5.0% of the purchase price, or £850,000, will be held in escrow to and through December 1, 2013. The purchase price is $26,205,500 million, based on the actual exchange rate for British pound sterling to U.S. dollars achieved on April 18, 2013 for the acquisition of Orbital.

We financed the consideration paid to the shareholder of Orbital with a portion of the net proceeds received from a public offering of our $0.001 par value common stock that was registered on an SEC Form S-1 registration statement that was declared effective by the SEC on April 11, 2013. Subsequent to closing on this acquisition, Orbital Gas Systems, Ltd. became a wholly owned subsidiary of CUI Global, Inc.

The foregoing summary of the share purchase does not purport to be complete and is qualified in its entirety by reference to the share purchase agreement, which is attached as Exhibit 2.1 to our Form 8-K filed with the Commission on March 6, 2013 and is incorporated herein by reference.
