Illinois Tool Works (ITW) Q4 2025 earnings review
Execution Machine: Organic Growth Turns Positive, Guidance Hits Mark
ITW closed 2025 with momentum, delivering Q4 revenue of $4.1B (+4.1% YoY) and GAAP EPS of $2.72 (+7%). Crucially, organic growth accelerated to +1.3%, marking the strongest performance of the year after starting 2025 in negative territory. The company’s 'self-help' strategy remains the primary earnings driver: Enterprise Initiatives added 140 basis points to margins, pushing Q4 operating margin to 26.5%. Management initiated FY26 guidance calling for 7% EPS growth at the midpoint ($11.20), signaling confidence that the industrial cycle is turning in their favor.
🐂 Bull Case
ITW continues to expand margins regardless of the macro environment. Enterprise initiatives contributed 140bps to Q4 margins and 130bps for the full year. FY26 guidance expects another ~100bps contribution, providing a high floor for earnings growth.
Automotive OEM grew 5.5% in Q4 (1.9% organic) with 21.8% margins. Previous quarters highlighted China EVs as a key driver. This segment is outperforming global auto builds, validating the 'Customer-Back Innovation' strategy.
🐻 Bear Case
Construction Products remains the clear laggard, with organic revenue declining 3.5% in Q4. High interest rates continue to pressure residential and commercial builds, and this segment was the only one with negative organic growth in the quarter.
While EPS grew 7%, full-year revenue was up only 0.9%. The company relies heavily on cost-outs and efficiency (Enterprise Initiatives) rather than robust end-market demand. If the industrial recovery stalls, 'self-help' measures face diminishing returns.
⚖️ Verdict: 🟢
Bullish. ITW demonstrated a clean break from the negative organic growth trends of early 2025. With organic sales accelerating to +1.3% and guidance pointing to +1-3% in FY26, combined with best-in-class margin execution, the setup for 2026 is robust.
Key Themes
Enterprise Initiatives: The Margin Engine
This remains the most consistent driver of shareholder value. In Q4, these initiatives (80/20, strategic sourcing) contributed 140 basis points to operating margin. For FY26, management explicitly guides for another 100 bps contribution. This structural margin expansion allows ITW to grow EPS faster than revenue.
Automotive OEM Outperformance
Accelerating. Automotive OEM revenue grew 5.5% (1.9% organic) in Q4, significantly outperforming flat-to-down global auto build rates. Margins in this segment expanded 200 bps YoY to 21.8%. The segment has successfully pivoted to capture EV content, particularly in China (noted in prior calls), decoupling its growth from stagnant unit volumes.
Test & Measurement Recovery
Reversing. After struggling in early 2025 (Q1 -5.4%, Q3 -1.4%), the Test & Measurement segment flipped to positive organic growth of +1.8% in Q4. This suggests the semiconductor and electronics CapEx cycle, which dragged on results earlier in the year, has finally bottomed.
Construction Segment Weakness
Decelerating. Construction Products remains the primary weak spot, posting a -3.5% organic decline in Q4. While margins remain healthy at 29.0%, the top-line trend is negative and disconnected from the recovery seen in other industrial segments like Welding and Polymers. Rate sensitivity continues to bite.
Currency Winds Shift
Reversing. Foreign currency translation turned from a headwind earlier in the year to a +2.5% revenue tailwind in Q4. This added significant gloss to the reported numbers (4.1% reported growth vs 1.3% organic). Investors should watch if the dollar strengthens again in 2026, potentially removing this boost.
Customer-Back Innovation (CBI)
Stable. Management cited CBI as contributing 2.4% to full-year revenue growth. However, with full-year organic growth at 0.0%, this implies the base business (excluding innovation) eroded by ~2.4%. While innovation is working, it is currently fighting against portfolio simplification headwinds and base erosion.
Other KPIs
Conversion remains elite at 109% of Net Income. While down slightly from $996M in 24Q4, the conversion rate >100% confirms high earnings quality and supports the $375M quarterly share repurchases.
Accelerating. This segment was the standout performer for organic growth, jumping from -3.1% in Q3 to +4.7% in Q4. Margins remained robust at 29.0%, showing strong operating leverage.
Beat guidance. Final result exceeded the prior guidance mid-point of $10.45. While optically down from FY24's $11.71, FY24 included a massive one-time gain ($1.26/share from Wilsonart). On an adjusted basis, earnings quality improved.
Guidance
Accelerating. The midpoint ($11.20) implies ~7% growth over FY25's $10.49. This is consistent with ITW's long-term algorithm of growing EPS faster than revenue.
Accelerating. Implies a distinct improvement from FY25's +0.9% reported growth. Includes organic growth of 1-3%, suggesting management sees the industrial bottom in the rearview mirror.
Stable/Improving. The midpoint (27.0%) represents a ~70bps expansion over FY25's 26.3%. The company explicitly attributes 100bps of this to enterprise initiatives, providing high visibility.
Key Questions
Base Business Erosion
You cite a 2.4% contribution from Customer-Back Innovation for the year, yet full-year organic growth was flat (0.0%). Does this imply the core legacy portfolio is eroding at a 2.4% annual rate, and is this acceleration of erosion concerning?
Construction Outlook
Construction was the only segment with negative organic growth in Q4 (-3.5%). With interest rates potentially staying higher for longer, do you anticipate this segment returning to growth in FY26, or will it remain a drag on the portfolio?
Pricing vs. Volume in FY26
Of the 1-3% organic growth guided for FY26, how much is driven by volume recovery versus pricing actions? Are you seeing actual unit volume upticks in early 2026?
M&A Appetite
With free cash flow conversion expected >100% and a pristine balance sheet, does the 2026 guidance include any capital deployment for M&A, or is the focus purely on buybacks ($1.5B planned)?
