GenTek Inc. Agrees to be Acquired by
American Securities LLC for $38.00 Per Share in Cash

PARSIPPANY, N.J., September 28, 2009 — GenTek Inc. (NASDAQ: GETI), a leading provider of specialty inorganic chemical products and valve actuation systems and components for automotive and heavy duty/commercial engines, announced today that it has entered into a definitive agreement to be acquired by ASP GT Acquisition Corp.(ASP), a wholly-owned subsidiary of investment funds managed by American Securities LLC, a private equity firm.

Under the terms of the merger agreement, ASP will commence a tender offer to purchase for cash all of the outstanding shares of GenTek common stock at a price of $38.00 per share. The transaction is valued at $673 million consisting of equity value of approximately $411 million plus the assumption of net debt and similar liabilities of approximately $262 million. The tender offer is expected to commence on or before October 9, 2009 and to expire on the 20th business day from and including the commencement date, unless extended in accordance with the terms of the merger agreement and the applicable rules and regulations of the Securities and Exchange Commission. Following completion of the tender offer, the parties will complete a second-step merger in which any remaining shares of GenTek will be converted into the right to receive the same price per share paid in the tender offer, and GenTek will cease to be a public company. Holders of GenTek’s Tranche C Warrants will have the right to receive a cash payment net of their per share exercise price and $38.00.

William E. Redmond, Jr., GenTek’s President and CEO, said, “Following consideration of a full range of strategic alternatives, we are pleased to have reached this agreement with American Securities which creates substantial value for our stockholders. This transaction represents a premium of 40.7% over GenTek’s closing share price of $27.00 on September 25,2009, the last trading day before the merger agreement was signed. In addition, we believe that the transaction will have a positive outcome for our customers and employees.”

The Board of Directors of GenTek has unanimously approved the merger agreement and the transactions contemplated by the merger agreement, and has resolved to recommend that GenTek’s stockholders tender their shares in connection with the tender offer contemplated by the merger agreement. The closing of the tender offer by ASP is subject to certain conditions, including a minimum tender condition. In addition, upon closing of the tender offer and assuming the minimum tender condition is satisfied, ASP has been granted the option to purchase all authorized but unissued shares from GenTek that would enable ASP to hold one share more than 90% of GenTek’s outstanding common stock.

Moelis & Company is acting as financial advisor to GenTek and has delivered a fairness opinion to the GenTek Board. Latham & Watkins LLP is legal counsel to GenTek.
