•The company is raising its guidance for full year 2024 revenue and EBITDA after adjusting for the separation of Atmus.

•Full year revenues are expected to decline 2% to 5%; prior guidance was also down 2% to 5% but assumed the inclusion of Atmus revenues for the full year.

COLUMBUS, IND. - Cummins Inc. (NYSE: CMI) today reported results for the first quarter of 2024.

“We continued to see strong demand from customers in the first quarter of 2024, reflecting the quality and performance of our products,” said Jennifer Rumsey, Chair and CEO. “We delivered solid profitability and also completed the separation of Atmus, allowing Cummins to continue its focus on advancing innovative power solutions and positioning Atmus to pursue its own plans for profitable growth. I am deeply appreciative of our Cummins employees across the globe, whose broad expertise and diverse perspectives are driving our ability to innovate for our customers and meet global demand.”

First quarter revenues of $8.4 billion decreased 1% from the same quarter in 2023. Sales in North America were flat, and international revenues decreased 1% due to lower demand in China and Europe.

Net income attributable to Cummins in the first quarter was $2.0 billion, or $14.03 per diluted share, compared to $790 million, or $5.55 per diluted share, in 2023. The results reflect the gain related to the separation of Atmus, net of transaction costs and other expenses, of $1.3 billion, or $9.08 per diluted share, and restructuring expenses of $29 million, or $0.15 per diluted share. The first quarter of 2023 included costs related to the separation of Atmus of $18 million, or $0.10 per diluted share. The tax rate in the first quarter was 8.7%, primarily due to the nontaxable gain on the separation of Atmus.

Earnings before interest, taxes, depreciation and amortization (EBITDA) in the first quarter were $2.6 billion, or 30.6% of sales, compared to $1.4 billion, or 16.1% of sales, a year ago. EBITDA for the first quarter of 2024 and the first quarter of 2023 included the gain and costs noted above.

Based on its current forecast, Cummins projects full year 2024 revenues to decline 2% to 5% on a year-over-year basis, and EBITDA to be in the range of 14.5% and 15.5% of sales.

The prior guidance, which was also a decline of 2% to 5%, assumed the inclusion of the financial results of Atmus for the full year. Due to strong global demand, the revenue guidance is unchanged as compared to the prior guidance despite the separation of Atmus. The current EBITDA guidance is an increase from the prior guidance of between 14.4% and 15.4%.

Cummins plans to continue to generate strong operating cash flow and returns for shareholders and is committed to our long-term strategic goal of returning 50% of operating cash flow back to shareholders. In the near term, we will focus on reinvesting for profitable growth, dividends and reducing debt.

“We have raised our expectations on revenue and profitability for 2024 due to continued demand for Cummins’ products and services. We do still expect slowing demand in some of our key markets in the second half of the year,” said Rumsey. “Despite lower sales, Cummins is in a strong position to keep investing in future growth, bringing new technologies to customers and returning cash to shareholders.”

•In March, Cummins finalized the separation of Atmus Filtration Technologies Inc. through a share exchange offer in which shareholders had the option to exchange their shares of Cummins common stock for shares of Atmus. Following completion of the exchange offer, Cummins did not retain any outstanding shares of Atmus common stock.

•Accelera™ by Cummins, Daimler Trucks & Buses and PACCAR selected Marshall County, Mississippi, as the future site of advanced battery cell manufacturing for their planned joint venture. The joint venture will localize battery cell production for commercial electric vehicles and is expected to create more than 2,000 U.S. manufacturing jobs, with the option for further expansion as demand grows. The 21-gigawatt hour (GWh) factory is expected to begin producing battery cells in 2027.

•Cummins re-introduced the fuel agnostic platforms with a name that captures the innovation that powers the business forward, the Cummins HELM™ platforms. With higher efficiency, lower emissions and multiple fuels, the Cummins HELM™ platforms give customers control of how they navigate their own journeys as part of the energy transition. As the next product in the Cummins HELM™15-liter platform, Cummins announced it will launch the next generation diesel X15 in North America for the heavy-duty on-highway market which will be compliant with U.S. EPA and CARB 2027 aligned regulations at launch.

•In April, Cummins Power Generation introduced four new generator sets to the award-winning CentumTM Series, two each powered by Cummins’ QSK50 and QSK78 engines. In response to high market demand, these new models have been engineered specifically for the most critical applications such as data centers, healthcare facilities and wastewater treatment plants. These products build on decades of experience meeting our customers' needs and deliver a step-change improvement in power density, assured reliability, sustainability and low emissions.

•Cummins received several prestigious honors during the quarter including being ranked in the Financial Times Diversity Leaders list for the third consecutive year, winning the World 50 Inclusion & Diversity Impact Award, and being named industry leader in the Commercial Vehicle and Machinery category for America’s Most JUST Companies list. Also, Cummins was named a 2024 Handshake Early Talent Award winner for its role in shaping the workforce of the future and was recognized as a 2024 Top Hispanic Employer by DiversityComm Magazine.

Equity, royalty and interest income from investees included in our Condensed Consolidated Statements of Net Income for the reporting periods was as follows:

On March 18, 2024, we completed the divestiture of our remaining 80.5 percent ownership of Atmus common stock through a tax-free split-off. The transaction involved the exchange of our shares in Atmus for shares of Cummins stock with a 7.0 percent discount on the exchange ratio for Atmus shares. The exchange ratio was determined based on each entity's respective stock price using the daily volume weighted-average stock price for three days preceding the final exchange offer date. Based on the final exchange ratio, we exchanged all 67 million of our Atmus shares for 5.6 million shares of Cummins stock, which was recorded as treasury stock based on the fair value of the Cummins shares obtained.

We evaluated the full divestiture of Atmus and determined the transaction did not qualify for discontinued operation presentation. We recognized a gain related to the divestiture of approximately $1.3 billion (based on the difference between the fair value of the Cummins shares obtained less the carrying value of our Atmus investment), which was recorded as other income in the Condensed Consolidated Statements of Net Income for the three months ended March 31, 2024. Approximately $114 million of goodwill was included in the carrying value of the Atmus investment for purposes of calculating the gain. The operating results of Atmus were reported in the Condensed Consolidated Financial Statements through March 18, 2024, the date of divestiture.

Our effective tax rate for 2024 is expected to approximate 24.0 percent, excluding any discrete items that may arise.

Our effective tax rates for the three months ended March 31, 2024 and 2023, were 8.7 percent and 21.7 percent, respectively.

The three months ended March 31, 2024, contained favorable discrete tax items primarily due to the $1.3 billion non-taxable gain on the Atmus split-off. Other discrete tax items were $21 million favorable primarily due to adjustments related to audit settlements.

The three months ended March 31, 2023, contained favorable discrete tax items of $3 million, primarily due to share-based compensation tax benefits.

We believe EBITDA is a useful measure of our operating performance as it assists investors and debt holders in comparing our performance on a consistent basis without regard to financing methods, capital structure, income taxes or depreciation and amortization methods, which can vary significantly depending upon many factors. We believe EBITDA excluding special items is a useful measure of our operating performance without regard to the impact of the gain recognized and costs associated with the divestiture of Atmus and restructuring actions. This statement excludes forward looking measures of EBITDA where a reconciliation to the corresponding accounting principles generally accepted in the United States (GAAP) measures is not available due to the variability, complexity and limited visibility of non-cash items that are excluded from the non-GAAP outlook measure.

EBITDA is not in accordance with, or an alternative for, GAAP and may not be consistent with measures used by other companies. It should be considered supplemental data; however, the amounts included in the EBITDA calculation are derived from amounts included in the Condensed Consolidated Statements of Net Income. Below is a reconciliation of net income attributable to Cummins Inc. to EBITDA for each of the applicable periods:

We believe these are useful measures of our operating performance for the periods presented as they illustrate our operating performance without regard to the gain recognized and costs associated with the divestiture of Atmus and restructuring actions. These measures are not in accordance with, or an alternative for GAAP and may not be consistent with measures used by other companies. This should be considered supplemental data.
