Theragenics® (TGX) Announces Plans to Repurchase up to $10 Million of Its Shares

Theragenics Corporation^® (NYSE: TGX), a medical device company serving the surgical products and prostate cancer treatment markets, today announced it is commencing a modified “Dutch Auction” tender offer to purchase up to $10 million of its common stock. Under the terms of the tender offer, Theragenics stockholders will have the opportunity to tender some or all of their shares at a price within a range of $2.00 to $2.40 per share. Based on the number of shares tendered and the prices specified by the tendering stockholders, Theragenics will determine the lowest per share price within the range that will enable it to buy $10 million of its shares, or such lesser number of shares that are properly tendered. All shares accepted for payment will be purchased at the same price, regardless of whether a stockholder tendered such shares at a lower price within the range. At the minimum price of $2.00 per share, Theragenics would repurchase a maximum of 5,000,000 shares, which represents approximately 14% of Theragenics’ currently outstanding common stock. Theragenics will fund this repurchase from available cash on hand. The low and high ends of the price range for the tender offer represent premiums of approximately 14% and 36%, respectively, to the closing price per share of $1.76 for Theragenics’ common stock on June 11, 2012, the last trading day prior to the announcement of the tender offer.

”The strength of our balance sheet allows us to fund this $10 million repurchase offer from available cash on hand,” stated M. Christine Jacobs, Chairman and CEO of Theragenics. “We expect our remaining cash and investment balances plus the ongoing cash flows from our business to allow us to continue to pursue other facets of our strategic plan.”

The tender offer will be subject to various terms and conditions as will be described in offer materials that will be publicly filed and distributed to stockholders on or about June 12, 2012. Additional copies of the offer materials will also be available from the information agent, Georgeson Inc. The dealer manager for the tender offer will be Georgeson Securities Corporation, and the depositary for the tender offer will be Computershare Trust Company, N.A.

None of Theragenics’ management, its board of directors and executive officers, the information agent or the depositary is making any recommendation to stockholders as to whether to tender or refrain from tendering their shares in the proposed tender offer. Theragenics’ directors and executive officers have advised the Company that they do not intend to tender shares in the offer. Stockholders must decide how many shares they will tender, if any, and the price within the stated range at which they will tender their shares.
