FLOWSERVE CORP

There are numerous factors that affect our business, financial condition, results of operations, cash flows, reputation and/or prospects, many of which are beyond our control. In addition to other information set forth in this Quarterly Report, careful consideration should be given to "Item 1A. Risk Factors" in Part I and "Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations" in Part II of our 2025 Annual Report, which contain descriptions of significant factors that might cause the actual results of operations in future periods to differ materially from those currently projected in the forward-looking statements contained therein.

There have been no material changes in risk factors discussed in our 2025 Annual Report and subsequent SEC filings. The risks described in this Quarterly Report filed for the period ended September 30, 2026, our 2025 Annual Report and in our other SEC filings or press releases from time to time are not the only risks we face. Additional risks and uncertainties are currently deemed immaterial based on management's assessment of currently available information, which remains subject to change; however, new risks that are currently unknown to us may surface in the future that materially adversely affect our business, financial condition, results of operations or cash flows.
