Cummins (CMI) Q1 FY26 earnings call: guidance and Q&A

How much of Q1 Power Systems margin was one-time, and what is the cadence for the rest of the year?

Mark declined to quantify the one-time precisely but cited stronger China demand (H1-weighted, weaker H2), net tariff recoveries, and some one-time cost recovery as above-plan contributors. Absent those, back out normal seasonality with a slightly softer Q4 on fewer production days; otherwise margins should be fairly even.

“if you just factor in a slightly slower Q4 because of the lower production days, the rest of the quarter should look pretty even for the remainder.”

Are there meaningful fuel-efficiency gains on the new heavy-duty engine, and is the medium-duty engine ready — what if it slips to 2028?

Jennifer confirmed a decision to delay the B platform launch to January 2028 (final Diesel HELM launch) due to late regulatory changes, while X15 and X10 proceed in 2027. The current B Series will be sold through 2027, phasing product launches; a modest H2 heavy-duty prebuy is still anticipated.

“we have made the decision to delay the launch of our B platform to January '28, that will be the final launch of our Diesel HELM platform.”

How far out do 95-liter lead times extend, and can Power Systems sustain its ~45% incremental margins as production ramps?

Jennifer noted 95-liter capacity was doubled last year with strong multiyear demand underpinning the raise, deferring specifics to the May 21 Analyst Day. Mark expressed high confidence in Power Systems, said prospects have strengthened in recent months, and reaffirmed the goal of expanding margins as revenue grows while continuing to invest.

“they've only strengthened, Jerry, even in in the last few months. So we are very optimistic, confident, maybe optimistic, is not the right word, confident in the performance in the Power Systems business.”

What is a fair Engine incremental margin given rolling-off launch spend but higher warranty on new platforms?

Mark explained new platforms start with a fresh warranty accrual rate, fixed for the first ~6 quarters until field experience allows reductions; 2027 platforms will begin with higher accruals. Combined with tariffs (heaviest on Engine) and the peak-investment period ending, incremental margins should improve over the next 18 months.

“when we launch a brand-new platform, we start with a new warranty accrual rate, and that's usually fixed for the first 6 quarters until we get enough field experience”

Why are rest-of-year incrementals only ~7% in Distribution and ~19% in Components, and how full are 2026 heavy-duty build slots?

Mark attributed low Distribution incrementals to parts growth lagging whole-goods/power-gen equipment and tougher Q2/Q3 pricing comps, with no one-time item. Jennifer cited rising truck orders, improved spot rates, and EPA'27 anticipation lifting demand — Cummins is adding a third shift at Rocky Mount and watching supply-base constraints as a gate on upside.

“the rate of growth at parts is not keeping pace with the rate of growth in whole goods, as we refer to them, or power generation equipment.”

What are the underlying tariff puts and takes, and where are benefits vs headwinds netting out?

Mark declined a segment-by-segment breakdown but reiterated a very small net EBITDA impact; the gross full-year impact is now ~20-30 bps (down from the prior ~0.5% estimate). Jennifer added that Cummins predominantly makes/sources in the US and is working with the Department of Commerce on an engine-offset program (Section 232), which is reflected in guidance though not finalized.

“That large number is still large, is probably just a little bit less now, 20 to 30 basis points full year impact.”

What was price realization in the quarter, and how do Q2-Q4 builds/Engine margins ramp?

Mark said price/cost was a very modest positive overall, not significant. On cadence, builds step up in Q2 and again in Q3, with Q4 seasonally lower on fewer OEM production days and product transitions; the rest of the year should be as good or better than Q1.

“price/cost was a very modest positive overall, I would say, not significant.”

Why is implied engine pricing down YoY and sequentially despite improving demand, and when does it move higher?

Mark attributed the decline to mix (on- vs off-highway, NA vs international, parts included in revenue but not unit counts) rather than any per-unit price cut. He reiterated 2027 emissions content adds are expected to be largely powertrain-related and content-driven.

“There's no significant change on a per unit basis to most -- what you've really got is a mix going on between what's being sold in the quarter”
