INVITATION TO 2026 ANNUALMEETING OF SHAREHOLDERS

Dear Fellow Shareholder:

I invite you to join Flowserve’s Annual Meeting of Shareholders on May 14, 2026. More information about our meeting topics and

agenda can be found in this Notice and Proxy Statement.

Elevated Growth

2025 was a remarkable year for Flowserve. We delivered outstanding results, including significant EPS growth of 24 percent, adjusted

EPS 1 growth of 38 percent, and strong operating cash flow for the full year. At the same time, our disciplined execution driven by the

Flowserve Business System enabled us to achieve our long-term margin targets two years ahead of schedule.

Our 3D strategy has made Flowserve more resilient to cyclicality than ever before, supported by consistent and durable bookings in

diverse end markets and expanded aftermarket opportunities. We remain excited about the significant opportunities in nuclear and

traditional power, with notable project awards in these markets, in addition to broadly positive trends in most of the other end markets.

Given our progress to date and positive momentum entering 2026, we are also looking ahead to how we further strengthen Flowserve

for the future. As we drive even greater focus on strategic growth markets, we are confident we will expand on our proven strengths to

drive continued growth increasing shareholder value for years to come.

I’m very proud of our accomplishments in 2025 and pleased with the value we were able to generate for our shareholders.

2025 Highlights include:

(1)Non-GAAP financial measure; see Annex I to this Proxy Statement for a reconciliation of such measure to the most directly comparable GAAP

financial measure. Adjusted EPS excludes realignment expenses, the impact from other specific discrete and below-the-line foreign currency effects

and utilizes the then-applicable foreign exchange rates and fully diluted shares.

Our Business Strategy

In 2024, we introduced the Flowserve Business System – a comprehensive framework that

defines how we align our processes across the enterprise to deliver sustainable, long-term

success for Flowserve. These five disciplines help our processes drive the desired outcomes

and priorities in the center of the Business System: profitable growth, margin expansion, cycle

resiliency, and customer experience.

People Excellence encompasses the programs that unlock the power of associates to enable

our enterprise strategy, underscored by our commitments to development and leadership.

Operational Excellence has strengthened our core operational capabilities and execution

abilities to differentiate the customer experience. Portfolio Excellence has been fully

embedded across all product business units, with the CORE 80/20 methodology as a key

lever of achieving our long-term margin targets two years early. We have made meaningful

progress integrating Commercial Excellence into the business through training and tools

enablement, and it will prove to be a critical growth enabler within the Business System as we

target sustained bookings and revenue growth. Finally, in 2026, we will broaden Innovation

Excellence beyond product and customer solutions to include internal processes and

functional productivity to support efficiency in delivering solutions to our customers.

We intentionally surround the Flowserve Business System with culture, strategy and execution because a winning company has to be

great at all of them. Our associates fully embraced and applied the Flowserve Business System in 2025, enabling us to achieve

operational and financial targets ahead of schedule. Looking ahead, we will regularly refine impact areas of the Flowserve Business

System to continue its effectiveness in how we run the company.

Executive Compensation Highlights (Page 30)

Compensation Philosophy and Principles

Pay for Performance Alignment

Our annual incentive program paid out above target in 2025. The 2025 payout aligned with our robust

shareholder return for the year and was driven by strong execution of the Flowserve Business System and

above-target adjusted operating income.

Incentive Plan” beginning on page 39.

(2)Customer bookings is calculated as the weighted average of the payout for the customer bookings for our divisions and is not a sum of the

attained performance of the divisions.

(3)Adjusted Primary Working Capital (“PWC”) as a % of Sales incentivizes efficiency. Lower percentage values indicate higher levels of

performance, reflecting an inverse relationship. The Corporate threshold was 28.0%. Actual performance of 28.8% resulted in no payout.

Following below target payouts for three performance cycles, 2023 PSUs were earned at 214.8% of target due to

the Company’s disciplined approach to capital allocation and robust shareholder return for the

performance period.

2025 Executive Total Compensation Mix

The majority of the total target compensation provided to our Named Executive Officers is “at risk” and aligned with our

compensation philosophy and principals to drive shareho lder value creation.

CEO Target Compensation Mix

Other NEO Average Target Compensation Mix

*At risk variable compensation is comprised of the target value of annual cash incentive and stock-based awards, as their value is tied to our

performance results against our financial and operational targets, our stock price, or both.

Engagement with Shareholders

Engagement with Shareholders

Flowserve regularly engages with current and potential shareholders to better understand their views of the Company’s

strategy, performance, and results. We review the results of the annual advisory vote on executive compensation in

making determinations about the structure of Flowserve’s pay program, and whether any changes to the program should

be considered.

In the fall of 2025, we proactively reached out to our top 25 shareholders, representing approximately 63% of our common

shares outstanding to offer them the opportunity to discuss our corporate governance practices with members of

management and to solicit feedback from our shareholders on these topics. The feedback we received was positive and

has been and continues to be carefully considered by management and the Board as we further develop our

compensation practices.

Flowserve, including our CEO and CFO, participated in investor conferences, in-person meetings and video conference

calls in 2025. This combination of meeting venues furthered our active engagement with Flowserve shareholders. We

value the views and perspectives that our shareholders and the financial community provide during these interactions,

and we formally communicate the information and feedback that we obtain to the Board and its Committees on a

regular basis.

We anticipate in 2026 that we will continue to have both in-person and virtual opportunities to continue our shareholder

outreach, which management and the Board find extremely valuable.
