United Rentals reported Q1 2026 revenue of $3.985 billion (+7.2% year-over-year), adjusted EPS of $9.71, and raised full-year guidance — and the 10-Q filed April 22, 2026 lets a retail reader see the margin picture management's headline compression language hides. Net margin printed 13.32%, down 60 basis points year-over-year. Back out the $29 million after-tax benefit from the 2025 H&E merger break-up (which will not recur) and the new $45 million Q1 2026 restructuring charge (which did not exist last year), and underlying net margin is about +20 basis points year-over-year. The segment split shows the real operating story: General rentals gross margin +150 bps to 33.8% while Specialty gross margin -170 bps to 41.4% on a mix-driven drag that is not in the press release's one-sentence treatment.
CSX Corp.'s Q1 2026 10-Q, filed April 22, 2026, shows operating margin hitting 36.0% — a 558 basis-point year-over-year expansion and the best Q1 in the eight-quarter window MetricDuck tracks. The 10-Q rail-segment footnote discloses a $44 million gain on property disposition embedded inside the $153 million expense decline — a line the 8-K press release and the earnings-call narrative did not itemize. Backing it out, 'core' margin expansion is closer to 430bps and underlying operating-income growth is about +16%, not the headline +20%. Freight receivables also jumped 15.4% quarter-over-quarter against flat sequential revenue, creating a $130 million working-capital drag that softens the cash-earnings story.
While Caterpillar is up +60% YTD, most see it as construction/mining. But CAT's Energy & Transportation segment—which powers AI data centers—is the real growth story at +16.8% YoY with stable 20% margins.
Honeywell is spinning into THREE companies by 2026. But while management focuses on restructuring, ROIC has quietly declined from 26.3% to 19.4% over 8 quarters. Here's what's dragging down returns and which segments might escape the trap.
