Record revenue and core business: Consolidated revenue of $1.566 billion; Transmission segment delivered a record quarterly revenue of $860 million
Guidance and cash flow: Full-year guidance raised; adjusted free cash flow of $281 million (a quarterly record)
Q2 2026 consolidated revenue came in at $1.566 billion, above the $1.506 billion consensus reported before the release. A large portion of the increase came from the consolidation of the Allison Off-Highway business acquired on January 1, 2026, which contributed $706 million in quarterly revenue, while the legacy Transmission business also grew 6% year-over-year to post its highest quarterly revenue on record. Adjusted diluted EPS of $2.73 exceeded the $2.59 analyst estimate and rose 8% from a year earlier. Adjusted EBITDA reached $404 million (26% of revenue), up 29% year-over-year.
Cash generation was also strong. Operating cash flow of $312 million (+70% year-over-year) and adjusted free cash flow of $281 million (+84% year-over-year) set quarterly records. The company returned capital and deleveraged in parallel, paying a quarterly dividend of $0.29 per share, repurchasing $46 million of stock, and retiring the remaining $150 million balance on its revolving credit facility. Management raised its 2026 full-year guidance, citing Q2 results and an improved end-market backdrop.
Negatives
GAAP earnings decline: Net income of $181 million and diluted EPS of $2.15, both down year-over-year
Off-Highway margin gap: Off-Highway gross margin of 17% and operating margin of 7% trail the core business (46% and 33%)
Ag demand delay: The agricultural end market shows early signs of recovery, but a meaningful rebound is still lacking
On a GAAP basis, net income of $181 million (12% of revenue) was $14 million lower than the prior-year quarter's $195 million, and diluted EPS of $2.15 fell 6% year-over-year. Management cited higher depreciation and amortization tied to the Off-Highway acquisition, increased net interest expense, and unrealized losses on marketable securities. Because the consensus is on an adjusted basis, EPS comparisons should be made using adjusted figures; on a GAAP-only basis, the comparison represents a step backward.
By segment, the Transmission business remained highly profitable with a gross margin of 46% and a segment operating margin of 33%, while Off-Highway posted a gross margin of 17%, segment operating income of $47 million (7% of revenue), and an adjusted EBITDA margin of 15% — meaningfully below the core business. One-time acquisition and integration costs (including $9 million in SG&A), along with inventory step-up and depreciation charges, are likely to persist in the near term. Management also assessed that the agricultural end market is showing recovery signals in certain segments and regions but has not yet turned meaningfully higher.
What Management Said
Management's tone leaned toward emphasizing core-business growth alongside acquisition integration. Chair, President and CEO David Graziosi attributed the Transmission segment's record quarterly revenue to defense end-market growth initiatives and momentum in the North American truck market. On the Off-Highway side, he noted that construction and materials handling and mining demand are recovering off lows, while drawing a line at agriculture, which has not yet returned to a meaningful recovery.
For the full-year guidance raise, management pointed to Q2 results and an improved end-market backdrop. At the same time, the company disclosed that approximately $140 million in pre-tax one-time costs related to Off-Highway separation, integration, and restructuring, around $75 million tied to inventory step-up, and an additional $50 million in depreciation are baked into the full-year net income guidance, and that even after factoring in one-time costs, the deal is accretive to 2026 net income and diluted EPS. The market read the adjusted earnings beat and guidance raise positively but appeared to weigh them against the decline in GAAP earnings, integration costs, and the segment margin gap, leading to a measured immediate stock reaction.
Market Reaction and Forward Watchpoints
Even with an adjusted EPS and revenue beat coupled with a guidance raise, after-hours movement was essentially flat. Alongside the possibility that expectations had already been largely priced in during the regular session, the natural read is that the decline in GAAP net income, Off-Highway acquisition-related costs, the lower Off-Highway margin versus the core business, and the agricultural demand delay offset the positives. The takeaway is a wait-and-see stance: "the numbers themselves are fine, but we want to see more of the post-acquisition profitability trajectory."
Whether Off-Highway margin improvement and the pace of planned synergy capture drive consolidated profitability going forward needs to be confirmed.
Whether the agricultural end market rebounds meaningfully, and whether defense and North American truck momentum persists, should be checked in next quarter's segment commentary.
How actual one-time costs and incremental depreciation track against the midpoint of the full-year net income guidance warrants monitoring.
