Cummins (NYSE:CMI) Q1 2026 revenue of USD 8.4 billion beat estimates, with Power Systems delivering record performance driven by data centre demand, though GAAP EPS of USD 4.71 missed consensus due to USD 199 million in charges from the sale of its low-pressure fuel cell business.

Key Highlights

  • Revenue of USD 8.4 billion grew 2.7% year over year, beating the USD 8.32 billion analyst estimate.
  • GAAP diluted EPS of USD 4.71 missed the USD 5.55 consensus, including USD 1.44 per share in charges from the fuel cell business sale.
  • Power Systems segment posted record EBITDA of USD 577 million, or 29.5% of sales, up from 23.6% a year ago.
  • Full-year 2026 revenue guidance raised to up 8% to 11%, from prior guidance of up 3% to 8%.
  • Full-year EBITDA margin guidance raised to 17.75% to 18.50%, from 17.0% to 18.0%.

A Quarter of Two Narratives

Cummins (NYSE:CMI) delivered a first quarter that requires careful separation of operating performance from one-time charges. On the surface, GAAP diluted EPS of USD 4.71 fell well short of the USD 5.55 analyst consensus, a 15.1% miss. Net income attributable to Cummins declined to USD 654 million from USD 824 million in Q1 2025, and EBITDA margin compressed to 15.4% from 17.9% a year earlier.

However, the quarter included USD 199 million in charges, equivalent to USD 1.44 per diluted share, related to the sale of the company's low-pressure fuel cell business on March 31, 2026. Excluding these charges, EBITDA of USD 1.49 billion represented a margin of 17.7%, broadly in line with the prior-year period and consistent with the company's longer-term profitability profile. The EPS miss, in this context, is largely a function of an accounting event rather than a deterioration in the underlying commercial engine.

Revenue of USD 8.4 billion grew 3% year over year, beating the USD 8.32 billion estimate. North America revenues declined 6%, reflecting softness in medium-duty and heavy-duty truck demand, while international revenues expanded 16%, led by stronger construction and industrial activity in China.

Power Systems: The Quarter's Standout

The Power Systems segment delivered what management described as a record performance. Sales reached USD 2.0 billion, up 19% year over year, with EBITDA of USD 577 million representing a 29.5% margin, up from 23.6% in Q1 2025. Both North America and international revenues grew 19% and 18% respectively, driven by surging demand for power generation products across data centre applications in North America, China, and Asia Pacific.

The data centre demand tailwind is not a short-term phenomenon. Hyperscaler investment in AI infrastructure is driving sustained demand for backup and primary power generation systems at a pace that continues to outpace original forecasts. Cummins is positioned as a primary beneficiary of this structural shift, and the Power Systems segment's margin expansion illustrates the operating leverage available when volume in this higher-margin business accelerates.

The Distribution segment also contributed positively, with sales of USD 3.1 billion up 7% year over year. EBITDA margin expanded to 14.2% from 12.9%, driven by increased power generation demand, particularly for data centre applications, alongside aftermarket parts and service activity.

Engine and Components: Cyclical Pressure Continues

Against the Power Systems strength, the Engine and Components segments faced cyclical headwinds from the North American truck market. Engine segment sales of USD 2.7 billion declined 4% year over year, with North America revenues down 12% as medium-duty and heavy-duty truck demand remained depressed. EBITDA margin in the segment compressed sharply to 10.4% from 16.5% a year earlier, reflecting the volume deleverage that accompanies a cyclical trough in on-highway markets.

Components segment sales of USD 2.5 billion fell 5% year over year, with North America down 13%, partially offset by growth in China and Brazil. EBITDA margin edged down to 13.3% from 14.3%. Over the past two years, Components revenue has averaged declines of 10.8% annually, and Engine revenue has averaged declines of 6.3%, reflecting the prolonged softness in North American truck markets that began in 2024.

Management signalled that North America on-highway markets are beginning to recover from their cyclical low, a view that underpins the significantly upgraded full-year revenue guidance. Wall Street analysts project full-year EPS of USD 19.26, implying approximately 42% growth over the next twelve months, consistent with a cyclical recovery playing out alongside continued data centre-driven strength in Power Systems.

Accelera and the Fuel Cell Exit

The Accelera segment, Cummins' zero-emissions business, generated sales of USD 101 million, broadly flat year over year, but recorded an EBITDA loss of USD 277 million, of which USD 199 million related directly to the fuel cell divestiture. The decision to sell the low-pressure fuel cell business reflects a pragmatic reassessment of hydrogen adoption timelines. Management cited lower-than-expected adoption rates as the rationale, consistent with a broader recalibration across the industrial sector on near-term hydrogen commercialisation prospects.

Cummins indicated it remains committed to zero-emissions investment through its Destination Zero strategy, but will concentrate resources on the most commercially viable pathways. The exit reduces the ongoing EBITDA drag from Accelera and signals a more disciplined approach to capital allocation within the segment going forward.

Guidance Upgrade and Capital Returns

The full-year 2026 revenue guidance raise to up 8% to 11%, from a prior range of up 3% to 8%, is the most significant signal in the quarter. It implies Cummins is seeing demand strengthen across multiple end markets simultaneously, with North America on-highway recovery adding to the structural data centre tailwind. EBITDA margin guidance of 17.75% to 18.50% represents an improvement from the prior range and, critically, excludes the first-quarter fuel cell charges.

Cummins returned USD 519 million to shareholders in the quarter through dividends of USD 276 million and share repurchases of USD 243 million, consistent with its long-term commitment to return 50% of operating cash flow to shareholders. Free cash flow of USD 120 million improved significantly from negative USD 165 million in Q1 2025, driven by better working capital management despite higher receivables and inventory balances associated with the revenue increase.

Conclusion

Cummins' Q1 2026 results present a mixed but fundamentally constructive picture. The EPS miss is largely attributable to a discrete charge on the fuel cell divestiture rather than operational deterioration. Beneath that, Power Systems delivered record margins, Distribution accelerated, and management raised full-year guidance materially. The Engine and Components segments remain under near-term pressure, but management's commentary on North America truck market improvement provides a credible basis for the upgraded outlook. The combination of data centre-driven structural demand in Power Systems and a cyclical recovery in on-highway markets, if both materialise as guided, could support meaningful earnings growth through the remainder of 2026.
