MINNEAPOLIS (February 27, 2025) — Donaldson Company, Inc. (NYSE: DCI) (Donaldson or the Company), a global leader in technology-led filtration products and solutions, today reported second quarter fiscal 2025 generally accepted accounting principles (GAAP) net earnings of $95.9 million, compared with $98.7 million in fiscal 2024. Second quarter 2025 GAAP earnings per share (EPS)1 were $0.79 compared with 2024 EPS of $0.81. Second quarter 2025 adjusted EPS2,3 was $0.83. The tables attached to this press release include a reconciliation of GAAP to non-GAAP measures.

“The Donaldson team delivered robust margins this quarter, displaying resilience and agility despite ongoing macroeconomic headwinds,” said Tod Carpenter, chairman, president and chief executive officer. “We generated sales growth in Aftermarket, Aerospace and Defense, and Life Sciences, while also diligently managing costs and further optimizing operating expenses.

“Our diversified portfolio of businesses, once again, provides balance in an uncertain environment, giving us confidence in our ability to drive record earnings in fiscal 2025. We remain committed to delivering long-term value creation through the execution of our strategic initiatives, with a focus on new product innovation and investments across all verticals.”

1 All EPS figures refer to diluted EPS.

2 Adjusted EPS is a non-GAAP financial measure that excludes the impact of certain items not related to ongoing operations.

3 Second quarter fiscal 2025 adjusted results exclude $2.2 million of pre-tax restructuring charges related to footprint optimization and cost reduction initiatives as well as $4.4 million of business development charges.

Sales of $870.0 million declined 0.8% compared with 2024 driven by a 170 basis point negative impact from currency translation partially offset by pricing benefits.

Mobile Solutions segment (Mobile) sales decreased 0.5% as a result of headwinds from currency translation. Aftermarket sales increased 4.0% driven by strong market demand in the OEM channel. Off-Road and On-Road sales decreased 12.8% and 24.4%, respectively, from a decline in global equipment production mainly in agriculture and transportation markets.

Industrial Solutions segment (Industrial) sales decreased 3.7% mainly due to volume declines. Industrial Filtration Solutions (IFS) sales declined 7.5% as a result of slower investments in capex-based businesses and Power Generation project timing. Aerospace and Defense sales grew 18.7%, driven by robust Defense sales.

Life Sciences segment (Life Sciences) sales increased 9.2% from strong volume growth in Disk Drive.

Gross margin was 35.2%, flat versus 2024 with benefits from select input cost deflation offset by unfavorable sales mix.

Operating expenses as a percentage of sales were 20.7%, an increase from 20.4% in the prior year, due to restructuring and business development charges. Excluding these charges, adjusted operating expenses as a percentage of sales were 20.0%, down 40 basis points from 2024, due to disciplined expense management.

Operating income as a percentage of sales (operating margin) of 14.4% decreased 40 basis points year over year from 14.8% in 2024 driven by restructuring and business development charges. Adjusted operating margin was 15.2%, a 40-basis point year-over-year increase due to expense leverage.

Interest expense was $5.9 million versus $5.6 million a year ago due to higher interest rates. Other income, net increased to $5.4 million compared with $4.9 million in 2024, primarily from fewer foreign exchange losses versus prior year. The Company’s effective tax rate was 23.2% compared with 23.5% a year ago.

Year-to-date, Donaldson paid $64.6 million in dividends and repurchased 0.9% of its outstanding shares for $81.4 million.

Adjusted full-year EPS guidance is narrowed to between $3.60 and $3.68, excluding $0.06 of first half fiscal 2025 restructuring and business development charges, and the midpoint is consistent with previous guidance. 2024 GAAP and adjusted4 EPS were $3.38 and $3.42, respectively. Sales are forecast to be flat to up 4% compared with prior year, with a headwind from currency translation of roughly 1% and a pricing benefit of approximately 1%.

Mobile sales are projected to be down 1% to up 3% versus 2024. Off-Road sales are expected to decline mid-single digits due to end-market weakness, particularly in agriculture. On-Road sales are forecast to decrease low-double digits due to an exit from non-strategic product sales combined with a decline in global truck production. Aftermarket sales are projected to increase low-single digits, driven by robust OEM channel demand and market share gains.

Industrial sales are forecast to grow between 1% and 5% year over year. IFS sales are projected to increase low-single digits with growth across most businesses, including dust collection, Industrial Hydraulics and Industrial Gases. Aerospace and Defense sales are expected to increase high-single digits as robust end-market conditions continue.

Life Sciences sales are forecast to grow high-single digits compared with 2024 driven by growth in Disk Drive and Food & Beverage.

4 Fiscal 2024 adjusted results exclude $6.4 million of pre-tax restructuring and other charges largely related to footprint optimization and cost reduction initiatives.

Adjusted operating margin, resulting from solid gross margin and operating expense leverage, is expected to be between 15.6% and 16.0%, up from previous guidance of 15.3% and 15.9%, and versus 15.2%, or 15.4% on an adjusted basis, in 2024.

Interest expense is estimated to be approximately $21 million and other income is forecast to be between $18 million and $20 million. Donaldson projects a fiscal 2025 effective income tax rate of between 23% and 25%.

Capital expenditures are forecast to be between $85 million and $100 million and free cash flow conversion is expected to be between 85% and 95%. For the full year, Donaldson anticipates repurchasing 2% to 3% of its shares outstanding.

2025 Adjusted EPS Guidance

A reconciliation of the Company’s fiscal 2025 adjusted EPS guidance to fiscal 2025 GAAP EPS guidance is not included in this release due to the number of variables in the projected GAAP EPS range and the Company’s current inability to reasonably quantify certain amounts, such as restructuring or other charges, that would be included in the GAAP measure or the individual adjustments for such reconciliation.

Note: Although free cash flow, EBITDA, adjusted EBITDA, adjusted gross profit, adjusted operating expense, adjusted operating income, adjusted net earnings and adjusted diluted EPS are not measures of financial performance under GAAP, the Company believes they are useful in understanding its financial results. Free cash flow is a commonly used measure of a company’s ability to generate cash in excess of its operating needs. EBITDA is a commonly used measure of operating earnings less non-cash expenses. The adjusted basis presentation excludes the impact of certain matters not related to the Company’s ongoing operations. Management believes that the adjusted basis presentation reflects management’s performance in operating the Company and provides a meaningful representation of the performance of the Company’s core business and is useful to understanding its financial results. A shortcoming of these financial measures is that they do not reflect the Company’s actual results under GAAP. Management does not intend these items to be considered in isolation or as a substitute for the related GAAP measures. Amounts may not foot due to rounding.
