Company Description: Flowserve is a leading manufacturer of flow control systems, including pumps, valves, and seals, for the global infrastructure markets. The company operates in two divisions: Flowserve Pump Division (FPD) and Flow Control Division (FCD).

Current Stock Price: ~$85 (closes, Feb 6, 2026)

Market Capitalization: About $11.2 billion

Rating: Flowserve trades at a forward P/E ratio of approx 20.6x based on the midpoint of 2026 EPS guidance. This represents a premium compared to historical levels, supported by the early attainment of long-term margin targets and double-digit earnings growth expectations.

Strong Margin Expansion Offsets Muted Lively Revenue

Flowserve reported earnings for the fourth quarter of 2025 $1.22 billionup 3.5% year on year but below analyst consensus approx $1.26–$1.27 billion. Adjusted earnings per share (EPS) was achieved $1.11a 59% increase from $0.70 over the past year and beyond $0.94 prediction.

• Adjusted Operating Margin: 16.8%, up 420 base points year after year.
• Adjusted Gross Margin: 36%, up 320 base points.
• Booking: $1.2 billion, up 3% YoY; aftermarket bookings increased 10.4% to $682.3 million.

In the full year 2025, the total revenue has increased ~4% to $4.73 billion. Adjusted EPS was $3.64up from $2.63 in 2024. The company has produced $506 million with money from jobs, up 19% year after year.

2026 Direction and Strategic Outlook

Management has initiated 2026 adjusted EPS guidance for $4.00 to $4.20representing ~13% growing in the center. Total sales growth is expected by 5% to 7%with projected organic income growth 1% to 3%.

The vision highlights the acceleration in the nuclear and electric power markets, approx $100 million on nuclear bookings in Q4. The pending acquisition of Trillium Flow Technologies’ Valves Division (expected near mid-2026) is expected to be neutral to 2026 earnings.

Macro Pressures and Geopolitical Exposure

Flowserve continues to experience customer project delays and inventory fluctuations, which reduced organic revenue by approx. 50 base points of q4. A change in the backlog is expected 76% in 2026 due to long-term nuclear projects.

The company is vulnerable to country risks in regions such as the Middle East, where increased costs are expected to support the booking of the first machines later in 2026. Supply chain disruptions and potential tax impacts on material costs remain an ongoing concern for global operations.

Power
