## Exhibit 99.1

**Exhibit 99.1** 

**Flowserve Underscores Commitment to Driving Value Creation for Shareholders** 

**DALLAS, May 28, 2026** – Flowserve Corporation (NYSE: FLS) ("Flowserve" or the "Company"), a leading provider of flow control products and services for the global infrastructure markets, today issued the following statement in response to a letter issued by Starboard Value LP (collectively with its affiliates, "Starboard").

The Flowserve Board of Directors (the "Board") and management team are committed to acting in the best interests of the Company and all shareholders. We regularly engage with investors to better understand their perspectives, and we welcome constructive input that furthers our goal of creating sustainable, long-term value for all shareholders. To this end, members of Flowserve's management team have held discussions with Starboard in recent months.

The Company reaffirms its 2026 guidance, including adjusted operating margin expansion and double-digit adjusted EPS growth. Additionally, the management team remains committed to its 2030 financial targets of mid-single digit organic sales CAGR from 2025-2030, 20% adjusted operating margin by 2030, and double-digit adjusted EPS CAGR from 2025-2030.

The strength of our aftermarket franchise and a resurgent power and nuclear end market fueled by AI growth, data center development and broader electrification trends provide a strong backdrop for growth. The current geopolitical environment should drive increased investment in energy security and diversification globally, providing another long-term tailwind for the Company. In addition, strong cash generation continues to facilitate disciplined, value-creating capital deployment, such as the acquisition of the Valves Division of Trillium Flow Technologies, as well as the return of $365 million to shareholders in 2025, including $255 million in share repurchases.

The Board and management team will continue to take action to drive sustainable growth, expand margins and enhance cash flow, thereby increasing value for all shareholders.

**About Flowserve** 

Flowserve Corporation is one of the world's leading providers of fluid motion and control products and services. Operating in more than 50 countries, the Company produces engineered and industrial pumps, seals and valves as well as a range of related flow management services.

------

The Company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). However, management believes that non-GAAP financial measures which exclude certain non-recurring items present additional useful comparisons between current results and results in prior operating periods, providing investors with a clearer view of the underlying trends of the business. Management also uses these non-GAAP financial measures in making financial, operating, planning and compensation decisions and in evaluating the Company's performance. Non-GAAP financial measures, which may be inconsistent with similarly captioned measures presented by other companies, should be viewed in addition to, and not as a substitute for, the Company's reported results prepared in accordance with GAAP.

All forward-looking statements included in this news release are based on information available to us on the date hereof, and we assume no obligation to update any forward-looking statement.
