Flowserve Corporation (FLS) | The Buildout — AI Infrastructure
The Verdict
Flowserve makes precision-engineered flow-control equipment — pumps, valves, seals, automation — and the aftermarket parts and services that keep those systems running. Its link to the AI build-out is indirect: rising electricity demand feeds investment in power and nuclear generation, where Flowserve supplies flow-control and aftermarket support.

What We Like
- Aftermarket bookings have run above $600M for eight consecutive quarters and hit a record $696M in Q2 2026.
- Nuclear awards were $400M in FY2025 and over $110M in Q1 2026, a roughly $100M-per-quarter run-rate.
- Adjusted gross margin has expanded year over year for 13 consecutive quarters; Q1 2026 adjusted gross margin was 37.2%, up 370 bps.
- The Trillium acquisition adds nuclear-certified valves and actuators and raises content per large new reactor from about $100M to $115–120M.
- FY26 guidance keeps adjusted EPS at $4.00–$4.20 and calls for about 100 bps of adjusted operating margin expansion.
What We’re Watching
- Second-half 2026 OE bookings ramp is load-bearing; Q1 organic revenue was roughly -10%, against full-year organic guide of -1% to +2%.
- Middle East rebuild is expected to begin later in 2026, but guidance assumes no material escalation.
- The Q2 2026 release digest omits segment detail, EPS, and updated full-year guidance.
- Trillium synergy quantification was still 'a couple of months out' as of April 30, 2026.
Thesis intact but timing-dependent. Aftermarket durability, nuclear awards, and self-help margins support the case, while the top line depends on a second-half OE recovery and Middle East rebuild. The key open question is whether the strong Q2 bookings accelerate into reported revenue before year-end.
Earnings Beat
Flowserve's Q2 2026 revenue was $1,169.2 million, gross margin was 32.9%, and EBITDA was $175.7 million, or 15.0% of revenue. Net income was $99.0 million and free cash flow was $112.3 million. Bookings were $1.35 billion, up 26% year over year, with record aftermarket bookings of $696 million; operating margin was 13.0% and adjusted operating margin was 15.3%, both up 70 bps.

|---|---|---|---|---|
| Revenue | $1.2B | $1.1B | $1.2B | −1.6% |

Management Guidance
The Q2 2026 release did not update full-year guidance. The most recent guidance, from the Q1 call, is organic sales of -1% to +2%, total sales of +3% to +6%, about 100 bps of adjusted operating margin expansion, and adjusted EPS of $4.00 to $4.20.
Trajectory
The revenue pattern is choppy. Flowserve reported a 6.7% year-over-year decline in Q1 2026 on 10.5% organic, then rebounded 9.4% sequentially in Q2 to $1,169.2 million. Management attributed Q1 weakness to Middle East disruption and a soft January/February MRO start; Q2 bookings of $1.35 billion, up 26% year over year, indicate improving demand, but full Q2 detail is absent from the source set. Gross margin stepped down from 37.1% in Q1 to 32.9% in Q2, while EBITDA margin was 15.0%.
The Model
The model projects FY+1 revenue of $4,950 million and EBITDA of $866 million, or a 17.5% margin, followed by FY+2 revenue of $5,250 million and EBITDA of $971 million, or an 18.5% margin. The near-term projection sits above the current trailing revenue base, while FY+2 assumes another advance in revenue and EBITDA margin.
| Metric | FY2025 | Next FY (E) | Following FY (E) |
|---|---|---|---|
| Revenue | $4.7B | $5.0B | $5.2B |
| YoY Growth | — | +4.7% | +6.1% |
| EBITDA | $673M | $866M | $971M |
| EBITDA Margin | 14.2% | 17.5% | 18.5% |
Projections are the median of 5 independent model runs. The model’s revenue sits 0.3% above analyst consensus.

What Could Go Right — and Wrong
- Confirmed European new-reactor awards arrive during 2026, converting nuclear expectations into reported orders.
- A U.S. new nuclear program moves from discussion to a concrete build-out commitment.
- Middle East rebuild and energy-security investment begins later in 2026 and turns into bookings.
- Trillium integration delivers quantified synergies and follows the Mogas playbook, lifting FCD margins.
- Scaled SMR work arrives sooner than the current 'couple of years away' expectation.
- Middle East conflict escalates beyond the no-escalation assumption, damaging revenue, bookings, and the earnings guide.
- The second-half OE bookings ramp does not arrive, leaving organic revenue short of the -1% to +2% guide.
- Nuclear-heavy backlog continues to convert slowly, keeping near-term OE revenue depressed.
- Trillium integration or synergy shortfalls make the deal less than neutral to adjusted earnings.
- 80/20 product-line walkaway cuts revenue deeper than the margin benefit.
Looking Ahead
Over the next 12 months the story tests whether project conversion catches up with bookings. Management expects European new-reactor awards during 2026, a possible U.S. nuclear build-out, and Middle East rebuild activity later in the year. Trillium synergy detail and the slow path to scaled SMR work are the other named milestones.
- 2H 2026OE bookings acceleration — Tests project, nuclear, and Middle East rebuild demand against the full-year guide.
- During 2026European new-reactor awards — Management expects awards; would confirm nuclear as an active order driver.
- Later 2026Middle East rebuild activity — Tests whether rebuild and energy-security demand becomes reported bookings.
- Later 2026Trillium synergy quantification — Management said detail was a couple of months out from April.

The Company
Flowserve designs and manufactures precision-engineered flow-control equipment — pumps, valves, seals, and automation — plus aftermarket parts and services. Its products keep materials moving and contained in energy, chemical, power generation, and water/pharmaceutical processes, the mechanical layer required before new power or nuclear capacity can run.
The company operates through two segments: Flowserve Pumps Division and Flow Control Division. It runs a global manufacturing and quick-response-center network, with about 800 associates in the Middle East, and services a large installed base through QRCs. The source set names no single plant or sole-source facility.
Business Segments
Competitive Landscape
The 10-K splits competition between pumps and valves and names large rivals including Sulzer, John Crane, Emerson, Baker Hughes, and Crane. It describes Flowserve as a 'world-leading' manufacturer and aftermarket provider, but supplies no market-share figures.
- Sulzer PumpsNamed in 10-K as one of Flowserve's largest pump/industrial competitors.
- John Crane Inc.Named in 10-K as a pump/industrial competitor; a unit of Smiths Group Plc.
- Named in 10-K as one of the largest valve competitors.
- Baker HughesNamed in 10-K as one of the largest valve competitors.
- Crane Co.Named in 10-K as one of the largest valve competitors.
Supply Chain
Flowserve sits between materials and component producers and operators of energy, chemical, power, and nuclear assets. No neighbor transcript in the source set mentioned Flowserve by name; its chain role is inferred from shared end markets.
