Timing note: August 4, 2026 is today, not tomorrow. This preview is therefore framed for CMI’s expected Q2 2026 release/call today before the U.S. market opens.
Cummins enters Q2 with a favorable setup—but also a high bar. The central debate is no longer whether Power Systems is strong; it is whether data-center-driven power demand, an improving North American truck backdrop, and reduced Accelera losses are strong enough to support another guidance raise or, at minimum, reinforce confidence in the company’s newly elevated medium-term targets.
The Street is looking for approximately $9.32 billion of revenue (+7.9% year over year) and $7.19 of EPS. The expected beat-or-miss will matter, but the more important determinants of the stock reaction are likely to be:
| Metric | Street expectation |
|---|---|
| Revenue | $9.32B |
| EPS | $7.19 |
| Power Systems revenue | $2.18B (+15.5% YoY) |
| Engine revenue | $3.03B (+4.5% YoY) |
| Components revenue | $2.78B (+3.0% YoY) |
| Distribution revenue | $3.38B (+11.3% YoY) |
These expectations imply broad-based growth, with the principal earnings engine still being Power Systems and its related Distribution activity—not simply a truck-cycle recovery.
CMI’s Power Systems business is benefiting from demand for backup generation equipment for data centers, particularly in North America and China. In Q1, Power Systems revenue rose 19%, while EBITDA margin reached 29.5%, helped by volume, pricing, operating leverage, tariff recoveries, and some non-recurring cost recoveries.
Management cautioned that Q1 Power Systems margins were unusually strong and should normalize somewhat through the rest of the year. That makes the Q2 margin print particularly important:
At its May Analyst Day, Cummins raised its 2030 targets to $45B–$50B of revenue and more than 20% EBITDA margin, supported heavily by power-generation growth. It expects data-center-related revenue across Power Systems and Distribution to grow from roughly $5B in 2026 to more than $9B by 2030. Q2 needs to validate that long-term framework.
In Q1, North American heavy- and medium-duty truck markets were still weak year over year, but Cummins said demand was improving sooner than it expected. It raised its 2026 North American heavy-duty truck forecast to 230,000–250,000 units, from 220,000–240,000, and lifted its medium-duty outlook to 125,000–135,000 units, from 110,000–120,000.
Management characterized Q2 as likely to be a strong build quarter, with Engines and Components expected to improve further in Q3. Key items to watch:
The prebuy could provide an additional tailwind into late 2026, but it also introduces a risk of softer demand after the regulatory transition. Cummins has said the X15 and X10 launches remain planned for 2027, while the new B-platform launch has moved to January 2028 amid regulatory uncertainty.
Following Q1, CMI guided for:
| 2026 guidance, issued with Q1 | Current range |
|---|---|
| Total company revenue | +8% to +11% |
| EBITDA margin | 17.75% to 18.5% |
| Power Systems revenue | +14% to +19% |
| Power Systems EBITDA margin | ~25% to 26% |
| Engine revenue | +7% to +12% |
| Engine EBITDA margin | 12.5% to 13.5% |
| Components revenue | +5% to +10% |
| Components EBITDA margin | 13.5% to 14.5% |
| Distribution revenue | +9% to +14% |
| Distribution EBITDA margin | 13.7% to 14.7% |
| Accelera EBITDA loss, excluding fuel-cell-sale charge | $270M–$300M |
A guidance raise would likely require management to express increased confidence in both data-center power demand and on-highway truck production. However, merely maintaining guidance could be sufficient if Power Systems margins normalize as previously telegraphed and the company preserves its strong second-half outlook.
What to watch - Growth in data-center-related generator demand; - China and broader Asia-Pacific demand; - Large-engine and genset capacity utilization; - Margin progression against the ~25%–26% full-year target; - Updates on orders, lead times, capacity additions, and future prime-power opportunities.
Why it matters Power Systems is the clearest source of CMI’s changed earnings profile. At the Analyst Day, Cummins announced an additional $450M investment intended to expand high-horsepower engine and genset capacity by 20 gigawatts, reaching 55 gigawatts by 2030. This is a large opportunity, but investors will want confirmation that demand visibility supports the capital deployment.
Distribution combines power-equipment sales, installation, parts, and service. Q1 revenue rose 7%, while EBITDA margin improved 130 basis points to 14.2%, driven by higher power-generation volumes and favorable mix.
What to watch - The split between power-generation equipment versus parts and service; - Margin durability as whole-goods power sales grow faster than higher-margin parts; - Data-center installation and balance-of-plant activity; - Aftermarket growth from Cummins’ expanding installed base.
Distribution is strategically important because it captures service and lifecycle value long after the initial engine or genset sale.
In Q1, Engine revenue fell 4% and Engine EBITDA margin fell to 10.4%, while Components revenue declined 5% and margin fell to 13.3%. The pressure was tied primarily to weaker North American truck volumes, higher costs, and continued investment ahead of the new emissions-platform launches.
The setup improves from here if truck builds strengthen. Beyond the near-term cycle, the EPA 2027 transition should raise content per vehicle across engines, aftertreatment, and related powertrain systems.
Watch for: evidence that the recovery is translating into volume rather than just optimistic order commentary; margin conversion as production rises; and any updated assumptions around the regulatory timetable.
Accelera remains a near-term drag, but the trajectory is improving. In Q1, the segment reported a $277M EBITDA loss, including a $199M charge related to the sale of the low-pressure fuel-cell business. Excluding that item, the loss improved to $78M from $86M a year earlier.
Cummins has been narrowing the portfolio, reducing exposure to slower-adoption hydrogen and electrolyzer opportunities, and focusing capital on areas such as battery-electric powertrains, e-axles, traction systems, and selected e-mobility markets.
Q2 read-through: Investors should focus on the underlying loss run rate and cash needs, not headline GAAP comparisons distorted by Q1’s divestiture-related charge.
CMI closed at $648.89 on August 3, down roughly 11% from its late-June high of $727.59 and modestly below its early-May level. That pullback may reduce some near-term valuation pressure, but expectations remain centered on the durability of the data-center power cycle and the company’s ability to translate elevated revenue into sustainably higher margins.
The most constructive Q2 outcome would be a Power Systems-led beat, continued Distribution strength, visibly improving truck volumes, and either raised guidance or a clear indication that the upper end of current ranges is increasingly achievable. The key downside scenario is not necessarily weaker reported EPS; it is evidence that Power Systems margins are normalizing faster than expected, truck recovery is less tangible than anticipated, or regulatory and tariff uncertainty is constraining management’s confidence.
