Weiss & Lurie, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by members of the Board of Directors of Frontier Oil Corporation (“Frontier” or the “Company”) (NYSE: FTO) arising from its proposed merger with Holly Corporation (“Holly”) (NYSE: HOC). Under the terms of the proposed transaction, Frontier shareholders will receive 0.4811 Holly shares for each Frontier share they hold, or approximately $26.99 per Frontier share, excluding the issuance of a special dividend. Weiss & Lurie is investigating whether Frontier’s Board acted in the best interests of shareholders in approving the transaction and whether the Board properly sought to maximize shareholder value. Notably, the total merger consideration is significantly below the $28.12 at which Frontier shares closed on the last market day before the transaction was announced, and is drastically lower than the target price of $33.00 per share recently set by at least one industry analyst. If you own Frontier shares and would like more information about your rights as a shareholder or additional information concerning our investigation, please contact Michael A. Rogovin either by email at email@example.com or by telephone at (888) 593-4771.
