GAAP EPS increased 30.4%; Adjusted EPS increased 9.8%

Donaldson increases fiscal 2022 sales and EPS guidance

Donaldson Company, Inc. (NYSE:DCI) (Donaldson or the Company) today reported second quarter 2022 net earnings of $71.8 million, an increase of 27.7% from $56.2 million in 2021. Earnings per share (EPS)¹ for the second quarter 2022 increased 30.4% to $0.57 from $0.44. The prior year EPS includes an impact of approximately $0.08 related to restructuring charges. Excluding this impact, second quarter 2022 EPS increased 9.8% from adjusted EPS² of $0.52 in 2021. The tables attached to this press release include a reconciliation of measures calculated in accordance with generally accepted accounting principles (GAAP) to non-GAAP measures.

"Second quarter record sales demonstrate the resiliency of our business model, the Donaldson team and our commitment to delivering value to our customers," said Tod Carpenter, chairman, president and chief executive officer. "Although ongoing inflation and supply chain challenges pressured gross margin more than we expected, we worked to mitigate the impact through our strategic pricing and expense management while continuing to invest for future growth.

"With the first half of the fiscal year behind us and given our expectations for robust sales through the balance of the year, we are increasing our fiscal 2022 sales and earnings guidance. Inflation and supply chain constraints are likely to remain a headwind, however, we expect our second half gross margins to improve sequentially as we realize increased benefits from pricing actions. More broadly, I am confident in the direction Donaldson is heading with our expanded global footprint, commitment to R&D, and integration and scaling of recent and future acquisitions."

¹ All earnings per share figures refer to diluted earnings per share.

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

Operating Results

Second quarter 2022 sales increased 18.2% to $802.5 million from $679.1 million in 2021, including a negative impact of 2.6 percentage points from currency translation.

Second quarter 2022 sales in the Engine Products segment (Engine) increased 19.8%, with Aerospace and Defense, Off-Road, and Aftermarket strength partially offset by a slight decrease in On-Road. Aerospace and Defense sales grew 29.6% compared with 2021, as stronger economic conditions in the commercial aerospace industry and market share gains drove results. Off-Road sales increased 22.6% versus the prior year, with growth in all regions as equipment production levels remained high and Exhaust and Emissions program wins in Europe bolstered results. Second quarter 2022 Aftermarket sales rose 20.6%, driven by strong demand across all primary end-markets. On-Road sales, down 0.7% year-over-year, continue to be negatively impacted by a strategic decision to discontinue sales of a low profit product line in the United States.

Second quarter Industrial Products segment (Industrial) sales rose 14.6%, with strong growth in Gas Turbine Systems (GTS) and Industrial Filtration Solutions (IFS). GTS sales increased 26.3% versus the prior year due to timing of project deliveries. IFS sales growth of 14.1% was the result of ongoing momentum in the industrial dust collection business as well as Process Filtration sales performance. Special Applications sales rose 9.8% compared with 2021, with growth in all regions and across the product portfolio.

Second quarter 2022 operating income as a percentage of sales (operating margin) increased to 11.9% from 11.2% in 2021. Second quarter 2021 adjusted operating margin, which excludes the impact of restructuring charges, was 13.4%. Gross margin decreased to 31.1% from 33.2% in the prior year, as inflation headwinds from raw materials, freight and labor costs persisted. Second quarter 2021 adjusted gross margin was 34.0%.

Second quarter 2022 operating expenses as a percentage of sales were 19.2%, an improvement from 22.0% in 2021 due to leverage on higher sales. Prior year adjusted operating expenses as a percentage of sales, which excludes $9.0 million of restructuring charges, was 20.7%.

Second quarter 2022 interest expense was $3.6 million, compared with $3.3 million in the prior year. Other income, net was favorable by $1.3 million versus the prior year, primarily driven by a reduction in donation expense. Second quarter 2022 effective tax rate increased to 24.1% from 23.9% in 2021.

During the second quarter, Donaldson paid dividends of $27.2 million and repurchased approximately 0.2% of its outstanding shares for $12.8 million. Year to date, the Company has paid $54.6 million in dividends and repurchased approximately 1.4% of its outstanding shares for $115.6 million.

Updated Fiscal 2022 Outlook

Donaldson is increasing its fiscal 2022 sales and EPS guidance to reflect a better-than-expected sales outlook given first half performance combined with additional pricing realization planned in the second half of the year. Net sales are projected to increase between 11% and 15% year-over-year, up from previous guidance of 8% to 12%. Currency translation is forecast to negatively impact sales by approximately 2%. Fiscal 2022 GAAP EPS is now expected to be between $2.66 and $2.76, versus a previous range of between $2.57 and $2.73. GAAP and adjusted EPS² in 2021 were $2.24 and $2.32, respectively.

Fiscal 2022 Engine sales are projected to increase between 12% to 16% compared with 2021 and versus previous guidance of an 8% to 12% increase. Incremental pricing and ongoing demand are expected to drive the overall improvement, particularly in the Aftermarket segment. Aerospace and Defense sales are also projected to increase versus previous expectations due to improved commercial aerospace market conditions and market share gains. Forecasts for Off-Road and On-Road performance are unchanged.

Fiscal 2022 gross margin is expected to be down between 1 to 1.5 percentage points compared with 2021 and versus the previous forecast of a decrease of 0.5 to 1 percentage point. Inflationary pressures were greater than expected in the first half and are anticipated to continue through the balance of the year.

Fiscal 2022 operating margin is forecast to be between 14.0% and 14.4% compared with previous guidance of between 14.1% and 14.7%. GAAP and adjusted operating margin were 13.5% and 14.0%, respectively, in 2021. Compared with 2021, leverage on higher sales and expense management will drive results.

The Company anticipates fiscal 2022 interest expense of approximately $14.0 million, and other income of between $7.0 million and $11.0 million. Donaldson expects a fiscal 2022 effective income tax rate of between 24% and 26%.

Fiscal 2022 capital expenditures are projected to be between $90.0 million and $110.0 million and free cash flow conversion is expected to be between 70% and 80%. Donaldson anticipates repurchasing approximately 2% of its outstanding shares during fiscal 2022.

Note: The constant currency presentation, which is a non-GAAP measure, excludes the impact of fluctuations in foreign currency exchange rates. The Company believes providing constant currency information provides valuable supplemental information regarding its results of operations. The Company calculates constant currency percentages by converting its current period local currency financial results using the prior period exchanges rates and compared these adjusted amounts to its prior period reported results. Amounts may not foot due to rounding.

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.
