Dril-Quip Challenges Accuracy of Glass Lewis Report and Urges Stockholders to Vote “FOR” Merger with Innovex

Glass Lewis declined to meet with Dril-Quip board and management and issued report that

contains unsubstantiated and misguided conclusions

Proposed transaction follows comprehensive assessment of standalone and strategic

alternatives and represents value maximizing outcome for Dril-Quip stockholders

Dril-Quip Board unanimously recommends stockholders vote “FOR” the transaction with

Innovex at the special meeting on September 5^th, 2024

HOUSTON—(BUSINESS WIRE)—Aug. 28, 2024—Dril-Quip, Inc. (NYSE: DRQ) (“Dril-Quip” or the “Company”) today commented on the report issued by Glass, Lewis & Co. (“Glass Lewis”) on August 23, 2024 and updated on August 27, 2024 in connection with the Company’s proposed merger with Innovex Downhole Solutions, Inc. (“Innovex”). Dril-Quip and its Board of Directors strongly disagree with the review and recommendations issued by Glass Lewis.

Dril-Quip and its Board of Directors believe the report should be revised to address the unsubstantiated and misguided conclusions and its disregard for the compelling rationale and financial benefits of the transaction. Dril-Quip and its advisors have repeatedly offered to hold discussions that would enable Glass Lewis to develop a fully informed opinion regarding the proposed merger with Innovex, but Glass Lewis has consistently declined to engage with the Company. As a result, the Company believes the Glass Lewis report provides a misguided review and recommendations to Dril-Quip stockholders.

“We are surprised by Glass Lewis’s decision to publish its recommendations without engaging in any dialogue with the Company,” said John V. Lovoi, Dril-Quip’s Chairman of the Board. “The report, issued without a prior meeting or discussion with the Company, contains unsupported conclusions, and does not capture the significant strategic and financial potential of this transaction. A meeting would have provided an opportunity to address any concerns and clarify the thoughtful and thorough process our Board undertook in reaching its decision to recommend the merger to our stockholders.”

Mr. Lovoi continued, “Dril-Quip and its Board of Directors continue to believe that this proposed transaction with Innovex is in the best interests of our stockholders. The Board is confident the merger will deliver significant value and strategic benefits that will enhance the Company’s long-term growth, resilience and prospects.”

Glass Lewis’s Comments on the Review Process Lack Factual Support: Dril-Quip and its Board of Directors Undertook a Comprehensive Process

Prior to entering into the proposed merger agreement with Innovex, Dril-Quip and its Board of Directors:

Glass Lewis’s report ignores the thorough process actually undertaken by the Board.

Glass Lewis’s Recommendations Fail to Appropriately Consider the Compelling Rationale and Financial Benefits of the Transaction

Despite recognizing the “strategic and financial impetus for the contemplated arrangement”¹, Glass Lewis’s recommendations fail to evaluate the compelling value outcome of the transaction relative to the Company on a standalone basis. Instead, Glass Lewis seeks support for its recommendations based on uninformed and misguided process perspectives (as outlined above) and a small number of other miscellaneous and isolated deal observations for which Glass Lewis offers no or little explanation as to how it justifies its recommendations. For example, the report mentions a special dividend by Innovex in isolation, focusing on the beneficiary rather than considering the overall context of the transaction, the incremental pro forma ownership it provides to Dril-Quip’s stockholders, or the fact that the combined company maintains a net cash position. Moreover, Glass Lewis neglects to balance such observations against the compelling rationale and financial benefits of the transaction in any way.

The merger of Dril-Quip and Innovex is immediately and significantly accretive on all metrics to Dril-Quip stockholders and offers the following strategic merits:

The Dril-Quip Board of Directors unanimously recommends that Dril-Quip stockholders vote “FOR” the transaction and each of the proposals to be considered at the special meeting, which will be held on Thursday, September 5, 2024, at 9:30 a.m. Central Time.

Following extensive discussions with stockholders, Dril-Quip and Innovex withdrew the charter amendment proposal (Proposal No. 2) and the related non-binding governance proposals (Proposal Nos. 3A – F), eliminating the requirement that stockholders approve these proposals as a condition of the closing of the merger. This withdrawal reflects our responsiveness to stockholder input and commitment to strong corporate governance practices.
