Kirby McInerney LLP is investigating potential claims against the Board of Directors of Vanguard Health Systems, Inc. (“Vanguard” or the “Company”) (NYSE: VHS) related to the proposed acquisition of the Company by Tenet Healthcare Corporation (“Tenet”) (NYSE: THC). Under the terms of the definitive agreement, Tenet will purchase all of the outstanding common stock of Vanguard for $21.00 per share in cash, for a total transaction value of approximately $4.3 billion including the assumption of $2.5 billion of Vanguard debt. The investigation concerns whether the Vanguard Board of Directors violated its fiduciary duties by agreeing to this transaction and whether the proposed $21.00 per share consideration adequately values Vanguard common shares. If you are a Vanguard shareholder and wish to obtain additional information, please contact J. Brandon Walker, Esq. by email at firstname.lastname@example.org, by telephone at (212) 699-1145 or (888) 529-4787, or by filling out this contact form.
