Robbins Geller Rudman & Dowd LLP ("Robbins Geller") today announced that a class action has been commenced in the United States District Court for the Southern District of Ohio on behalf of holders of Robbins & Myers, Inc. ("R&M") (NYSE:RBN) common stock on August 9, 2012, against R&M, its Board of Directors (the "Board") and National OilWell Varco, Inc. ("NOVI") and NOVI's wholly owned subsidiary, Raven Process Corp. ("Merger Sub"), alleging breaches of fiduciary duty, and/or aiding and abetting those breaches, in connection with the Board's decision to sell R&M to NOVI via an inherently unfair process (the "Proposed Acquisition"), and violations of §§14(a) and 20(a) of the Securities Exchange Act of 1934 ("1934 Act") in connection with defendants' failure to disclose all material information to R&M shareholders in the Preliminary Proxy Statement filed by R&M with the SEC on August 31, 2012 (the "Proxy"). R&M is a supplier of engineered equipment and systems for critical applications in global energy, industrial, chemical and pharmaceutical markets.

If you wish to serve as lead plaintiff, you must move the Court no later than 60 days from today. If you wish to discuss this action or have any questions concerning this notice or your rights or interests, please contact plaintiff's counsel, Darren Robbins of Robbins Geller at 800/449-4900 or 619/231-1058, or via e-mail at djr@rgrdlaw.com. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.

On August 9, 2012, R&M, Merger Sub and NOVI announced they had entered into an agreement (the "Merger Agreement") under which NOVI will acquire R&M in an all-cash transaction that values R&M at approximately $2.5 billion. The complaint alleges that the Proposed Acquisition is the product of a fundamentally flawed process that is designed to ensure the acquisition of R&M by NOVI on terms preferential to NOVI and R&M's Board members, but detrimental to plaintiff and the other public stockholders of R&M, in breach of the Board's fiduciary duties.

The complaint further alleges that the Proxy filed on August 31, 2012 in connection with the Proposed Acquisition was false and misleading and omitted or misrepresented material information regarding the Proposed Acquisition in violation of §§14(a) and 20(a) of the 1934 Act and in contravention of the Board's fiduciary duties under state law. The Proxy failed to disclose material information regarding: (i) the sales process for the Company; (ii) strategic alternatives for the Company; (iii) the Company's financial projections; and (iv) the financial analyses conducted by Citi, the Company's financial advisor. Without this material information, the Company's public shareholders will be precluded from casting a fully informed vote in connection with the Proposed Acquisition.

Plaintiff seeks injunctive and equitable relief on behalf of holders of R&M common stock on August 9, 2012. The plaintiff is represented by Robbins Geller, which has expertise in prosecuting investor class actions and extensive experience in actions involving financial fraud.
