On November 20, 2014, Dresser-Rand Group Inc. (the “Company”) held a special meeting of the Company’s stockholders (the “Special Meeting”) to, among other things, consider and vote on a proposal (the “Merger Proposal”) to approve and adopt the Agreement and Plan of Merger, dated as of September 21, 2014 (the “Merger Agreement”), by and among the Company, Siemens Energy, Inc. (“Siemens”), and Dynamo Acquisition Corporation, a wholly owned subsidiary of Siemens (“Merger Sub”), whereby Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Siemens. The Merger Proposal and the other proposals outlined below were submitted to a vote of the stockholders, each of which is described in detail in the Company’s Definitive Proxy Statement on Schedule 14A that was filed with the U.S. Securities and Exchange Commission on October 22, 2014.

At the Special Meeting, 56,371,786 shares of the Company’s common stock, representing approximately 73.54% of the total number of shares of the Company’s common stock entitled to vote, were represented by the holders thereof or by proxy, which constituted a quorum. A summary of the matters voted upon by the Company’s stockholders is set forth below.

Proposal 1. Approval and Adoption of Agreement and Plan of Merger.

At the Special Meeting, the Company’s stockholders approved and adopted the Merger Agreement, based on the following votes:

Proposal 2. Approval of Adjournment of the Special Meeting, if necessary.

The proposal to approve an adjournment of the Special Meeting, if necessary, to solicit additional proxies in favor of the Merger Proposal if there are not sufficient votes at the time of such adjournment to approve and adopt the Merger Agreement was withdrawn at the Special Meeting, as sufficient votes were cast at the Special Meeting to approve the Merger Proposal.

Proposal 3. Advisory Resolution to Approve Executive Compensation.

Stockholders approved, on a non-binding, advisory basis, certain compensation that will or may be paid by the Company to its named executive officers that is based on or otherwise related to the Merger, based upon the votes set forth below:

On November 20, 2014, the Company issued a press release announcing the results of its stockholders’ vote at the Special Meeting, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
