Executive Summary
            
                Donaldson Company delivered a solid start to fiscal 2025 with total sales of $900.1 million, up 6% year over year, driven by volume growth across all three segments and modest pricing and currency benefits. The quarter showcased continued margin discipline, with gross margin of 35.6% and operating margin of 14.9%, supported by product mix and volume leverage. Management highlighted ongoing efficiency actions, including footprint optimization in Life Sciences, and a broader investment stance aimed at sustainable long-term profitability through capacity additions, new products, and strategic acquisitions.
Mobile Solutions led top-line growth via aftermarket share gains and expanded distribution capacity, Industrial Solutions benefited from strong Aerospace & Defense performance and rising connected solutions, while Life Sciences posted double-digit sales growth on Disk Drive and Food & Beverage strengths, albeit with a pre-tax loss driven by ramp costs in acquisitions. The balance sheet remains robust (net debt/EBITDA ≈ 0.6x), and the company reaffirmed a diligent capital deployment plan: capex of $85–$105 million, 85–95% cash conversion, and return of 2–3% of outstanding shares alongside a long-standing dividend track record. The guidance implies execution of a mid-single-digit top-line trajectory for the year with improving profitability as backlogs normalize, though Life Sciences profitability remains a key swing factor in the outlook.

            Management Commentary
            
                Theme: Strategy and growth priorities
- Quote: Tod Carpenter, CEO: “Our record first quarter earnings mark a strong start to fiscal 2025. We increased sales in all three segments, gained share in key business units through our technology-led solutions, and maintained strong gross margins.” This underscores a balanced mix shift toward higher-value filtration solutions and ongoing market-share gains across segments.
- Quote: Tod Carpenter, CEO: “We expanded our presence in food and beverage markets with the launch of filtration services in France, Germany, and Austria … sets the stage for further expansion and share gains across Europe.” This signals a geographic and vertical expansion push in Life Sciences-related markets.
Theme: Operational execution and demand environment
- Quote: Brad Pogalz, CFO: “Cash conversion is expected to be in the range of 85% to 95%, in line with historical averages.” Highlights disciplined cash management and a clear path to higher annual cash conversion with expected revenue growth.
- Quote: Tod Carpenter, CEO: “Backlogs remain high; as we work down our backlogs through the balance of this year, we expect profitability to improve as we get leverage on higher sales.” Indicates management’s view that near-term profitability will benefit from backlog-driven leverage.

            Forward Guidance
            
                Guidance and assessment:
- Revenue: Expect total sales to grow 2%–6% for fiscal 2025, factoring in approximately 1% pricing benefit and currency. This implies organic growth in the low-to-mid single digits, with Mobile Solutions flat to up 4%, Industrial Solutions up 4%–8%, and Life Sciences in the low double digits.
- Margin: Operating margin guidance unchanged at 15.3%–15.9%, with the midpoint up ~20 bps vs. prior year, reflecting ongoing leverage from higher volumes and targeted cost actions. This implies a still-strong profitability trajectory even as Life Sciences remains a near-term drag on pre-tax profitability.
- EPS: Adjusted EPS guidance reaffirmed at $3.56–$3.72 for FY2025; GAAP EPS will be influenced by Life Sciences’ restructuring actions and acquisitions ramp.
- Capital allocation: Capex guidance $85–$105 million; cash conversion 85%–95%; dividend policy continued (dividends with 69th year of quarterly payments) and 2%–3% share repurchase.
- Assessment: The outlook is achievable if Life Sciences normalization progresses, backlogs unwind in Industrial Solutions, and supply chain constraints ease in Aerospace & Defense. Risks include macro weakness in agricultural and global trucking markets (On-Rroad) and potential tariff or raw material cost volatility. Management’s emphasis on in-region manufacturing and strategic investments supports optionality for upside if project timing improves and backlogs normalize further.
