In April 2019, we announced that the Board determined that it was in the long-term best interest of the Company to exit the solar business segment and focus our strategic efforts on our semiconductor and silicon carbide/polishing business segments in order to more fully realize the opportunities the Company believes are presented in those areas.

The Board made its decision, effective March 28, 2019, after analyzing current market conditions and the strategic outlook for its Solar segment, which operates in a highly competitive market among lower cost manufacturers, particularly in China. Historical fluctuations in the solar cell industry combined with downward pricing pressure has negatively affected the Company’s results of operations in recent years. In response, we had been pursuing strategic alternatives for the continued operations of the Solar segment, including the possibility of restructuring the Solar segment to achieve profitability and compete more effectively. After further assessment, however (including input from management of the Solar segment and our external advisors), the Board determined that the investment required to return our solar business to profitability would be better utilized to pursue strategic opportunities in the Semiconductor and SiC/LED segments.

The anticipated divestiture of our solar business included our Tempress and SoLayTec subsidiaries, which comprised substantially all of our Solar segment. We adopted a plan to sell our Solar operations on or before March 31, 2020. As such, we classified substantially all of the Solar segment as held for sale in our Consolidated Balance Sheets and reported its results as discontinued operations in our Consolidated Statements of Operations. We expect to incur one-time costs to sell Tempress of approximately $750,000, which includes $500,000 in broker fees and $250,000 in legal fees, although the final amount could be greater if certain timing and/or price targets are met.

On June 7, 2019 (“Sale Date”), we completed the sale of our subsidiary, SoLayTec, to a third party located in the Netherlands. Upon the Sale Date, we recognized a gain of approximately $1.6 million, which we included in loss from discontinued operations reported in our Consolidated Statements of Operations for the year ended September 30, 2019. Also, effective on the Sale Date, SoLayTec is no longer included in our consolidated financial statements. SoLayTec is not material to Amtech’s results of operations or financial position.
