Simpson Manufacturing Co., Inc. Announces Capital Allocation Program and Share Repurchases

PLEASANTON, Calif., Sept. 22, 2015

On September 14, 2015, the Company entered into a Master Confirmation and a Supplemental Confirmation for an accelerated share repurchase program (the "ASR Agreement") with Wells Fargo Bank, National Association to repurchase approximately $25 million worth of Common Stock. The total number of shares that will be repurchased will be determined based on the daily volume weighted average market price of the Company's common stock, less a discount.

This action does not change the Company's overall growth strategy. The Company has a strong cash position and remains committed to seeking growth opportunities in the building products range where it can leverage its expertise in engineering, testing, manufacturing and distribution to invest in and grow its business. Those opportunities include internal improvements or acquisitions that fit within the Company's strategic growth plan. Additionally, the Company has financial flexibility and is committed to providing returns to its shareholders. Considering the Company's current strong cash position and balance sheet, the Company entered into the ASR Agreement as a means to repurchase shares under the remaining balance of the Authorization. Over the next three years, the Company currently plans to utilize future share repurchase authorizations and to consider future dividend increases, both of which will require approval by the Company's Board of Directors.
