Item 1.01 Entry into a Material Definitive Agreement.
On October 10, 2011, Amtech Systems, Inc. (the “Company”) entered into an amendment (the “Amendment”) to the Stock Purchase and Sale Agreement, dated January 27, 2011, among the Company, Kingstone Technology Hong Kong Limited (“Kingstone”), Silicon Jade Limited (“Silicon Jade”), the sole shareholder of Kingstone, and certain shareholders of Silicon Jade (the “Original Purchase Agreement”) to provide that the consideration in the aggregate amount of $5.5 million which was to be paid to Silicon Jade partly in cash and partly in stock of the Company will now be paid all in cash. The Amendment provides that the payment of cash to the shareholders of Silicon Jade be made to such shareholders consistent with the manner in which the stock was to be issued in the Original Purchase Agreement. The Amendment provides that a portion of the cash be paid out by the Company now and the remaining amount be deposited into escrow with such amounts to be distributed to the shareholders of Silicon Jade upon the achievement of specified milestones in the development of the Solar Tool.
