OnElection February 5, 2026, Flowserve Corporation, a New York corporation (the “Company”), issued a press release announcing financial results for the fourth quarter and full year ended December 31, 2025. A copy of ~~this~~Directors ~~press release is attached as Exhibit 99.1 and incorporated herein by reference.~~

On March 16, 2026, Flowserve Corporation (the “Company”) announced that Brian D. Savoy, Executive Vice President and Chief Financial Officer for Duke Energy Corporation (“Duke Energy”) has been elected by the Company’s Board of Directors (the “Board”) as a new member of the Board, effective March 16, 2026. Prior to Mr. Savoy’s appointment as Executive Vice President and Chief Financial Officer of Duke Energy in 2022, Mr. Savoy was the Senior Vice President and Chief Transformation and Administrative Officer of Duke Energy from 2019 to 2021 and the Senior Vice President, Business Transformation and Technology of Duke Energy from 2016 to 2019.

Mr. Savoy fills the newly created directorship resulting from the increase in the number of directors pursuant to resolutions duly adopted by the Board under the Company’s Amended and Restated By-Laws (as amended and restated, the “By-Laws”) disclosed in Item 5.03 below. In connection with his election to the Board, Mr. Savoy has also been appointed as a member of the Audit Committee and Technology, Innovation and Risk Committee of the Board. Mr. Savoy is expected to be nominated for reelection by the Company’s shareholders at the 2026 annual meeting of shareholders. There is no agreement or understanding between Mr. Savoy and any other person pursuant to which he was selected as a director. The Company anticipates reducing the number of directors following Ken Siegel’s previously announced departure from the Board following the expiration of Mr. Siegel’s term at the conclusion of the Company’s May 2026 annual meeting.

The Board has made an affirmative determination that Mr. Savoy qualifies as an independent director under the New York Stock Exchange listing standards and the Company’s standards for director independence and qualifies as independent for purposes of Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Board has also made the affirmative determination that Mr. Savoy qualifies as an “audit committee financial expert” as such term is defined under Item 407(d)(5) of Regulation S-K under the Exchange Act. There have been no transactions directly or indirectly involving Mr. Savoy that would be required to be disclosed pursuant to Item 404(a) of Regulation S-K under the Exchange Act.

Mr. Savoy will be compensated for his service on the Board in accordance with the Company’s compensatory and other arrangements for non-employee directors, which are described in detail in the Company’s definitive proxy statement dated April 2, 2025, under the heading “Director Compensation”.

Item 5.03

Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On March 12, 2026, the Board approved an amendment to the Company’s By-Laws, effective March 16, 2026. Article III, Section 2 of the By-Laws, which sets forth the number of directors of the Company, was amended by the Board to increase the number of directors of the Company from ten to eleven.

The foregoing description of the amendment contained in the By-Laws is qualified in its entirety by reference to the full text of, and should be read in conjunction with, the By-Laws, a copy of which is filed with this Current Report on Form 8-K as Exhibit 3.1 and incorporated herein by reference.

Such forward-looking statements are subject to numerous risks and uncertainties that are difficult to predict.

These risks and uncertainties may cause actual results to differ materially from what is forecast in such forward-looking statements, and include, without limitation, the following: global supply chain disruptions and the current inflationary environment could adversely affect the efficiency of our manufacturing and increase the cost of providing our products to customers; a portion of our bookings may not lead to completed sales, and our ability to convert bookings into revenues at acceptable profit margins; changes in global economic conditions and the potential for unexpected cancellations or delays of customer orders in our reported backlog; our dependence on our customers’ ability to make required capital investment and maintenance expenditures; if we are not able to successfully execute and realize the expected financial benefits from any restructuring and realignment initiatives, our business could be adversely affected; the substantial dependence of our sales on the success of the energy, chemical, power generation and general industries; the adverse impact of volatile raw materials prices on our products and operating margins; economic, political and other risks associated with our international operations, including military actions, trade embargoes, epidemics or pandemics and changes to tariffs or trade agreements that could affect customer markets, particularly North African, Latin American, Asian and Middle Eastern markets and global oil and gas producers, and non-compliance with U.S. export/re-export control, foreign corrupt practice laws, economic sanctions and import laws and regulations; the impact of public health emergencies, such as outbreaks of epidemics, pandemics, and contagious diseases, on our business and operations; increased aging and slower collection of receivables, particularly in Latin America and other emerging markets; potential adverse effects resulting from the implementation of new tariffs and related retaliatory actions and changes to or uncertainties related to tariffs and trade agreements; our exposure to fluctuations in foreign currency exchange rates, including in hyperinflationary countries such as Argentina; potential adverse consequences resulting from litigation to which we are a party, such as litigation involving asbestos-containing material claims; expectations regarding acquisitions and the integration of acquired businesses; the potential adverse impact of an impairment in the carrying value of goodwill or other intangible assets; our dependence upon third-party suppliers whose failure to perform timely could adversely affect our business operations; the highly competitive nature of the markets in which we operate; if we are not able to maintain our competitive position by successfully developing and introducing new products and integrate new technologies, including artificial intelligence and machine learning; environmental compliance costs and liabilities; potential work stoppages and other labor matters; access to public and private sources of debt financing; our inability to protect our intellectual property in the United States, as well as in foreign countries; obligations under our defined benefit pension plans; our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud; the recording of increased deferred tax asset valuation allowances in the future or the impact of tax law changes on such deferred tax assets could affect our operating results; our information technology infrastructure could be subject to service interruptions, data corruption, cyber-based attacks or network security breaches, which could disrupt our business operations and result in the loss of critical and confidential information; ineffective internal controls could impact the accuracy and timely reporting of our business and financial results; and other factors described from time to time in our filings with the Securities and Exchange Commission.
