Reporting Tuesday, August 4, 2026 (before market open) | 2026Q2 Earnings Call


The Setup

Cummins goes into this print as one of the year's momentum stories in industrials. The stock closed around $649 on Aug 3, having nearly doubled off its August 2025 low near $356. Notably, though, shares have cooled from their late-June peak of ~$728 (roughly 11% below the high), and traded soft into the print — dipping to ~$606 on July 29 before recovering. In other words, expectations are elevated but sentiment has become slightly less one-sided heading into the report.

The core narrative: a Power Systems / data center boom offsetting (and now outrunning) a North America truck market recovering off cyclical lows. Management has now raised full-year guidance twice this year, and the May 21 Analyst Day lifted 2030 targets, so the bar for a "beat-and-raise" continuation is high.


What the Street Expects

Consensus for Q2 2026 (per the pre-earnings digest):

Metric Q2 2026 Est. Q2 2025 Actual Implied Y/Y
Total revenue ~$9.32B $8.64B +7.9%
EPS ~$7.19 $6.43 +12%
Power Systems $2.18B $1.89B +15.5%
Engine $3.03B $2.90B +4.5%
Components $2.78B $2.71B +3%
Distribution $3.38B $3.04B +11.3%

For context, Q2 2025 delivered $8.64B revenue, EPS of $6.43, and 18.4% EBITDA margin. Q1 2026 came in at $8.4B revenue with 17.7% EBITDA margin ex-charge and $6.15 EPS ex-charge (GAAP EPS was $4.71 after a $1.44/share charge on the low-pressure fuel cell divestiture).


The Big Questions Into the Print

1. Does guidance get raised a third time?

This is the swing factor for the stock. On the Q1 call, CMI raised FY2026 revenue guidance to +8% to +11% (from +3% to +8%) and EBITDA margin to 17.75%–18.5% (from 17.0%–18.0%). Management explicitly said the first half is running stronger than expected while keeping the second half largely unchanged. With a "strong Q2 ahead" telegraphed, investors will want to see whether continued truck-market momentum and data-center strength push the outlook higher again — and, importantly, whether the beat is "quality" or reliant on one-timers.

2. Power Systems — can margins hold near record levels?

Power Systems is the crown jewel. Q1 posted a record 29.5% EBITDA margin (up from 23.6% a year ago) on 19% revenue growth. But management flagged that ~29.5% is not repeatable — it benefited from net tariff recoveries, front-half-weighted China demand, and one-time cost recoveries. Full-year guidance is 25%–26%, so a sequential step-down in Q2 margin is expected and should not spook investors. Watch the absolute EBITDA dollars and any commentary on the $450M capacity expansion (to 55 GW by 2030) and data-center order book.

3. North America truck — how much prebuy, how much recovery?

Q1 showed NA heavy-duty industry production down 23% y/y, but management said orders and spot rates inflected sharply — they're adding a third shift at Rocky Mount and ramping heavy-duty engine build rates from ~240/day early in the year toward ~400/day by end-June. FY guidance was raised to 230k–250k HD units and 125k–135k MD units. The key nuance: how much of 2H strength is genuine freight recovery versus prebuy ahead of the 2027 EPA rules, and whether supply-chain constraints cap the upside.

4. EPA 2027 regulatory clarity

A live overhang. Management delayed the B-series (7-liter) launch to January 2028 while keeping X15 and X10 on track for 2027, and is awaiting a revised draft rule (expected around this quarter). Any update on the final rule, potential non-compliance penalties, content-per-truck economics (industry estimates ~$10k of added content per truck, much of it in the powertrain where CMI plays), and pricing would be a meaningful catalyst.

5. China / international

China surprised to the upside in Q1 (+19% including JVs, with data-center power gen up 84%), driving a big guidance swing — full-year China revenue is now expected +10% vs. a prior -1%. Watch whether this momentum sustained into Q2, keeping in mind China power-gen demand tends to be first-half weighted.

6. Accelera losses and tariffs

Two clean-up items trending favorably: FY Accelera EBITDA loss guidance improved to -$270M to -$300M (from -$325M to -$355M) after the fuel-cell exit, and management continues to characterize the net tariff impact as immaterial to EBITDA. Confirmation of both supports the earnings-quality story.


Segment Guidance Scorecard (FY2026, post-Q1 raise)

Segment Revenue Guide EBITDA Margin Guide
Engine +7% to +12% 12.5%–13.5%
Components +5% to +10% 13.5%–14.5%
Distribution +9% to +14% 13.7%–14.7%
Power Systems +14% to +19% ~25%–26%
Accelera Rev $300–350M Loss $270–300M

Capital Returns & Balance Sheet

Cummins remains committed to returning ~50% of operating cash flow to shareholders. In Q1 it returned $519M ($243M buybacks at ~$537 avg, $276M dividends) — notably restarting repurchases. The dividend sits at $2.00/quarter (raised 16 consecutive years). With the stock now ~$650, watch whether buyback pace continues at higher prices. Q1 operating cash flow was a positive $309M (vs. a small outflow a year ago); working capital (receivables/inventory build to support the ramp) is worth monitoring as production scales.


Longer-Term Frame (from the May 21 Analyst Day)

Management raised 2030 targets to $45–50B revenue and >20% EBITDA margin (up from $43–48B and 17–18%), underpinned by a 6–9% revenue CAGR built on three roughly equal pillars: data-center growth, content/on-highway recovery, and other markets + aftermarket. Data-center revenue is targeted to grow from ~$5B in 2026 to >$9B by 2030, with new prime-power, natural gas (up to 4MW), and mining engine platforms broadening the story. This reframes CMI from a truck-cycle play toward a more diversified power franchise — a key reason for the multiple re-rating.


Bottom Line — What Matters Most Tomorrow

  1. The guidance raise (or lack thereof). After two hikes and a big rally, an in-line print with no further raise could disappoint; the stock is priced for continued upside.
  2. Power Systems EBITDA dollars and data-center order commentary — the primary earnings and narrative driver.
  3. Truck 2H cadence & prebuy visibility, plus any EPA-2027 rule clarity.
  4. Earnings quality — how much of any beat is durable (volume/content/aftermarket) vs. one-time (tariff recoveries, China timing).

Risk skew: With shares off their highs and having wobbled into the print, a clean beat-and-raise with sustained Power Systems margins could re-energize the stock; conversely, a "good but not raised" quarter — or Power Systems margin normalization read negatively — is the more likely source of a pullback given rich expectations.
