Pentair (PNR) Q4 2025 earnings review

Pool Segment Resurges, but Water Solutions Drags Anchor

Pentair ended FY25 with accelerating momentum. Q4 sales grew 5% YoY (up from 3% in Q3), driven by a sharp 11% rebound in the critical Pool segment. However, the portfolio remains bifurcated: while Pool and Flow are growing, Water Solutions deteriorated significantly, shrinking 10% YoY. Despite the top-line volatility, the margin story remains intact due to Transformation initiatives, with Adjusted ROS expanding 90 bps to 24.7%. Management's initial FY26 guidance suggests a continuation of this stable, moderate-growth compounding, targeting 7-10% Adjusted EPS growth.

🐂 Bull Case

Pool Segment Acceleration

The Pool segment—Pentair's highest margin business—is accelerating. Sales grew 11% YoY in Q4 (Core +9%), a significant step up from the 7% growth seen in Q3. This confirms the end of the destocking cycle and a return to volume growth.

Dividend Aristocrat Status

Pentair announced its 50th consecutive year of dividend increases. Combined with $748M in Free Cash Flow (+8% YoY), the capital allocation story remains a bedrock for investors.

🐻 Bear Case

Water Solutions Deterioration

Water Solutions is becoming a serious laggard. Sales dropped 10% YoY in Q4 (Core -4%), worsening from the -6% decline in Q3. Margin in this segment also compressed 60 bps to 23.5%.

Pool Margin Compression

Despite the 11% sales surge, Pool segment margins actually compressed 20 bps to 33.6%. Investors should monitor if Pentair is sacrificing pricing power or spending heavily to chase volume recovery.

⚖️ Verdict: 🟢

Bullish. The recovery in the Pool segment (the company's profit engine) is the most critical signal in this report. While Water Solutions is a concern, the overall acceleration in revenue and strong guidance for FY26 outweigh the pocket of weakness.

Key Themes

DRIVER🟢🟢

Pool Segment Recovery

The Pool segment has definitively turned the corner. After stabilizing in Q2/Q3, growth accelerated to +11% reported (+9% core) in Q4. This segment generates the highest margins (33.6%) for Pentair, so volume recovery here has an outsized impact on the bottom line. The recovery appears to be broad-based across the portfolio.

CONCERN🔴

Water Solutions Drag

Water Solutions is moving in the wrong direction. Q4 sales fell 10% (Core -4%), and margins contracted 60bps to 23.5%. This segment has faced headwinds from residential softness and portfolio rationalization throughout 2025, but the acceleration of the decline in Q4 is a red flag that requires explanation on the call.

DRIVER🟢

Margin Expansion via Transformation

The 'Transformation' and '80/20' initiatives continue to deliver. Despite flat ROS in GAAP terms, Adjusted ROS expanded 90 basis points to 24.7% in Q4 and 170 basis points to 25.2% for the full year. This structural margin improvement allows earnings to grow faster than sales (FY25 Sales +2% vs Adj EPS +14%).

THEMENEW

Leadership Re-alignment

The company announced new executive roles to 'better align' residential Flow and Water Solutions with distribution channels. This appears to be a direct response to the underperformance in Water Solutions and the need to streamline go-to-market strategies.

Other KPIs

Adjusted EPS (25FY)$4.92

Up 14% YoY. Beat the full-year guidance midpoint provided in previous quarters. The company effectively converted 2% top-line growth into double-digit earnings growth.

Free Cash Flow (25FY)$748 million

Up 8% ($55M) YoY. Cash conversion remains excellent, funding the dividend increase and $225M in share repurchases for the year ($50M in Q4).

Flow Segment Sales (25Q4)$394 million (+9%)

Accelerating. Up 9% YoY (Core +4%). The delta between reported and core likely reflects the Hydra-Stop acquisition contribution mentioned in Q3. Margins expanded significantly (+240 bps) to 22.8%.

Guidance

FY26 Adjusted EPS$5.25 - $5.40

Stable growth. Implies +7% to +10% growth over FY25. This aligns with the company's long-term algorithm of compounding earnings through modest sales growth and margin expansion.

FY26 Net Sales+3% to +4%

Accelerating. An improvement over the +2% achieved in FY25. Suggests management sees the Water Solutions drag stabilizing and Pool/Flow strength continuing.

Q1 26 Adjusted EPS$1.15 - $1.18

Accelerating. The midpoint ($1.165) implies ~5% growth over 25Q1 ($1.11). While positive, it is slower than the full-year target of 7-10%, suggesting a back-half weighted year.

Key Questions

Water Solutions Deterioration

Water Solutions sales worsened to -10% in Q4 from -6% in Q3. Is this purely residential macro weakness, or are there execution issues? When do you expect this segment to find a bottom?

Pool Margin Dynamics

Pool sales surged 11%, yet ROS compressed 20 bps YoY. Was this due to mix shift, promotional activity to drive volume, or one-time costs? Should we expect margins to re-expand as volume leverage kicks in during 2026?

Acquisition Contribution vs Core Growth

Flow segment reported +9% growth but only +4% core. Can you parse out the specific contribution and performance of the Hydra-Stop acquisition in the quarter?

Pricing Power in 2026

With inflation normalizing, what level of price realization is embedded in the +3-4% sales guidance for 2026?
