Exhibit 99.1 MAGELLAN HEALTH SERVICES 6950 Columbia Gateway Drive Columbia, MD 21046 www.magellanhealth.com FOR IMMEDIATE RELEASE - --------------------- INVESTOR CONTACT: Melissa Rose 877-645-6464 MEDIA CONTACT: Erin Somers 410-953-2405 MAGELLAN HEALTH SERVICES CLARIFIES AND CORRECTS CERTAIN INFORMATION REGARDING ITS FINANCIAL RESTRUCTURING -- COMPANY REITERATES IMPACT OF INCREASED SHARES AND RESULTING PRICES PER SHARE-- -- WARRANT EXERCISE PRICE IS CORRECTED -- COLUMBIA, Md. - January 7, 2004 - Magellan Health Services, Inc. (Nasdaq:MGLN) today clarified and corrected certain information regarding the transactions resulting from its emergence from Chapter 11 bankruptcy as previously disclosed on January 5, 2004. The Company reiterated the change in the number of shares of common stock that were issued under its plan of reorganization and the effect such increase had on certain per share prices. As previously disclosed, the Company was authorized in connection with implementing the plan to increase the number of shares to be issued pursuant to the plan to all parties proportionally. The Company increased the number of shares by 2.3 times the number stated in its plan, with the same effect as if the Company had effected a 2.3 stock split. All share amounts and per share prices were accordingly adjusted proportionally. The effect of the stock split on some of the key components of the plan of reorganization was as follows: Post-Split (as issued) ----------- Equity Value per Share as Set Forth in the Disclosure Statement.............................$9.39 to $11.57 Shares issued to Subordinated Note Holders............................20,518,830 (including 858,967 shares that elected Cash-Out Option) Price Paid by Onex for Shares Purchased Pursuant to Investment Commitment......................................$12.39 Price Paid by Onex for Shares Purchased to Fund Cash-Out Election..............................................$ 9.78 Price Paid by Creditors and Onex to Purchase Shares in Equity Offering..............................................$12.39 Total Shares Purchased by Onex.........................................8,415,580 Total Shares Issued and Outstanding...................................35,356,537 (including approximately 0.5 million shares being held pending the resolution of certain disputed claims in the bankruptcy) - more - MAGELLAN HEALTH SERVICES CLARIFIES AND CORRECTS CERTAIN INFORMATION REGARDING ITS FINANCIAL RESTRUCTURING - - PAGE 2 - The Company also announced today that it had entered into documents clarifying the terms of the warrants to purchase shares of its Ordinary Common Stock that it issued to the former holders of the common stock and the Series A Redeemable Preferred Stock of Magellan in connection with the consummation of the Chapter 11 in order to reflect correctly the stock split. The exercise price of the warrants was corrected so as to equal $30.46 (rather than $30.20 as previously announced), as required to give proper effect to the stock split. Pursuant to a Warrant Agreement entered into on January 5, 2004, warrants to purchase a total of 570,826 shares of Magellan's Ordinary Common Stock were issued to the former holders of common stock and Series A Redeemable Preferred Stock of Magellan as provided by the plan of reorganization. The Warrants are exercisable until January 5, 2011. The plan calls for such warrants to be issued at an exercise price determined by a formula which varies with the number of shares issued to other parties in accordance with the plan. The stock split made in connection with the implementation of the plan affected the exercise price of the warrants. A clerical error was made in the calculation of the exercise price applicable to the warrants after giving effect to this adjustment and the exercise price included in the Warrant Agreement and announced to be applicable to the warrants in the Company's January 5 press release and Form 8-K Current Report was incorrectly stated to be $30.20. The exercise price required by the plan, giving correct effect to the adjustment, was $30.46. In order to conform to this requirement and as permitted by the Warrant Agreement, Magellan has entered into corrective documents providing that the exercise price of the warrants is $30.46. No other terms of the Warrants were changed. About Magellan: Headquartered in Columbia, Md., Magellan Health Services (Nasdaq:MGLN) is the country's leading behavioral managed care organization.
