VMC Welcome Page Language
On December 12, 2011, Martin Marietta Materials, Inc. commenced an unsolicited exchange offer to acquire all outstanding common shares of Vulcan Materials Company. The Board of Directors of Vulcan, after consultation with its independent financial and legal advisors, unanimously determined that the Martin Marietta exchange offer was not in the best interests of Vulcans shareholders and recommended that Vulcan shareholders reject the offer.
On May 4, 2012, the Delaware Chancery Court ruled that Martin Marietta had breached two confidentiality agreements between the companies, and enjoined Martin Marietta for a period of four months from prosecuting a proxy contest, making an exchange or tender offer, or otherwise taking steps to acquire control of Vulcan shares or assets and from any further violations of the two confidentiality agreements between the parties. Martin Marietta has indicated an intent to appeal.
Vulcans Board and management team remain focused on enhancing value for all Vulcan shareholders. Vulcan is well positioned for growth, with superior aggregates operations and operating leverage, and we look forward to continuing to build shareholder value.
This website provides information from Vulcan Materials on these matters and on Vulcans strong value proposition. Please read all of these materials carefully.
We thank you for your continued support.
