Cummins Prints a Record Quarter and Gets De-Rated Anyway

18.9% EBITDA margin, orders into 2H 2028, a $200M shipment slip — and a 34% drawdown as the AI-power complex reprices

CMI · Earnings Call · 2026-11-05

The record nobody bid

Cummins delivered $9.4 billion of third-quarter revenue, up 13%, record EBITDA of $1.8 billion at 18.9% of sales, and a record 27.7% gross margin. Earnings per share of $8.25 nearly doubled. And yet the equity sits 34% lower over the last ninety trading days and 38% below its June peak, in an unbroken downtrend since early July. That divergence — flawless income statement, collapsing tape — is the whole story of this report. Guidance is where the crack shows. Full-year revenue growth was trimmed to approximately 10% from a 10%–13% range, and EBITDA margin to approximately 18.2% from 18%–18.5%. Management then framed the shortfall with unusual precision for a company that just posted records:

Half of it is supply chain issues, which we believe will catch up in the fourth quarter, and roughly half of it market conditions primarily related to lower pickup trucks.

Two very different problems hiding in one revenue line. The pickup engine business — lower pickup truck demand from elevated diesel and interest rates — was cut to 118,000–122,000 units from 125,000–140,000. That is end-market deterioration. The other half is a single supplier that failed in Power Systems: “we would have expected, let's say, about $200 million more of that revenue to incur in the third quarter that is rolled into the fourth quarter.” — Mark A. Smith, Chief Financial Officer · 2026-11-05 One is a demand question the market can argue about; the other is a timing question that resolves in ninety days. The tape is treating both as the former.

Power Systems is still the machine

The engine of the bull case did not crack. Power Systems revenue hit a record $2.3 billion, up 15%, with segment EBITDA margin of 25.4%, up 250 basis points on favorable pricing and power generation mix. Data center customers remain the company's single highest-momentum theme by a wide margin, and Power Systems is right behind it — the two keywords that define this quarter's narrative in Know Trend's own extraction. Jennifer Rumsey was unusually granular on forward visibility: “Our order intake in the third quarter exceeded what we thought it would be... orders extending out into the second half of 28.” — Jennifer W. Rumsey, Chair and Chief Executive Officer · 2026-11-05 That is a continuation, not a revelation — six months ago Mark Smith said essentially the same thing: “if you want a new one, it's going to be the second half of 2028.” — Mark Smith, Chief Financial Officer · 2026-08-04 What is genuinely incremental is the language about contractual commitments with hyperscalers extending beyond the firm order board, and the first material battery storage win. That win — a battery energy storage system for a large US data center, the company's largest such deployment — is new for Cummins and the analysts probed hard on whether it lifts the 2030 framework. The CFO's answer was disciplined to the point of deflating: likely to grow, but not the most significant factor in Power Systems guidance. A new capability, deliberately not sold as a new thesis.

What is actually being repriced

Step back from Cummins and the drawdown explains itself. Across the whole market, the AI data centers theme is the single largest cluster of decliners — down roughly 31% over thirty days across dozens of tickers, dragging co-packaged optics, high-bandwidth memory, and data center power names with it. Cummins, the backup-power vendor to the hyperscalers, is trading as a member of that complex rather than as a diesel engine company. The company once pitched itself as the defensive way in: “we are a low-risk weighted play on the AI boom.” — Mark Smith, Chief Financial Officer · 2026-02-05 When the complex de-rates, low-risk weighting buys you relative outperformance, not immunity. The internal evidence that demand has not broken is real. Supply chain is the constraint, not the order book: Supply chain constraints limited shipments in both power systems and distribution, and management expects to catch up. Fourth-quarter implied revenue growth of 15% is a step up, powered by a distribution segment that must grow 23% sequentially to hit guidance. Distribution's third-quarter margin fell to 13.9% from 15.5% precisely because of mix — fewer aftermarket parts, more big-ticket installations.

The quiet rot under the record

Three things deserve more attention than the headline. First, the electrolyzer problem stopped being a revenue problem. Two Hydrogenics subsidiaries issued a stop-use recommendation on HyLYZER electrolyzer products after a fleet data review, and “The potential financial impact of this remains under evaluation and is not reflected in our guidance.” — Mark A. Smith, Chief Financial Officer · 2026-11-05 Compare that to a year ago, when the same business was described as a decline that was “sharp and dramatic and merits further close review.” — Mark Smith, Chief Financial Officer · 2025-11-06 A sub-scale, shrinking business has now acquired an unquantified liability. That is the sort of thing a 34x price-to-earnings multiple has no room for. Second, the price/cost tailwind is gone. After quarters of modest positive pricing, Smith conceded “we are starting to see some creeping cost increases. Right? Freight's gone up... it is more of a slight headwind on price costs in the second half.” — Mark A. Smith, Chief Financial Officer · 2026-11-05 The margin expansion this quarter came from volume and operations, not price. Third, tariffs — the dominant macro theme for four straight quarters — have effectively vanished from the narrative: “The net impact of tariffs, if you are still asking about that, was immaterial in the quarter.” — Mark A. Smith, Chief Financial Officer · 2026-11-05 A year ago that same management team called tariffs “a big hindrance to our industry.” — Mark Smith, Chief Financial Officer · 2025-11-06 The theme that once explained every margin miss now explains nothing. Traders should note how quickly consensus macro anxieties are retired. One more disappearance: the prebuy thesis. In August, executives were still anticipating customers pulling orders forward ahead of EPA27. On this call: “what we have seen this year is been, we believe, pretty limited pre buy in The US truck market.” — Jennifer W. Rumsey, Chair and Chief Executive Officer · 2026-11-05 Non-conforming penalties are still expected to be passed through, with the EPA's final rule due in December — the same posture as the prior two calls. Nothing new there, which is itself the point.

The setup into year-end

Financially, Cummins is not strained. Effective net cash of −$3.7 billion improved 25% year over year, capex of $249 million in the quarter remains inside an unchanged $1.35–1.45 billion program, and $661 million went back to shareholders. A variable compensation expense headwind is the mechanical cost of record earnings — a quality-of-earnings quirk, not a deterioration. The bear case is not the balance sheet or the order book. It is that a stock priced for an AI power supercycle must keep beating and raising through it, and this quarter it did neither. The fourth quarter now has to deliver three things simultaneously: the $200 million of slipped shipments, a 23% distribution step-up, and Power Systems margins that the CFO explicitly warned are not a run rate. Cummins will probably deliver the numbers. Whether the market re-rates the complex is a different question entirely, and not one this company controls.
