ALSN — Q2 2026 Earnings Preview
Setup in one line
Q1 was an operational beat with an optical GAAP miss after the Jan 1 Off-Highway close. Management reaffirmed (did not raise) FY26 sales $5.575B–$5.925B and Adj EBITDA $1.365B–$1.515B while parking all $120M run-rate synergies outside 2026. Q2 is the first sequential test of Off-Highway seasonality (mgmt: step-up vs Q1), Defense continuity at the Q1 run-rate, and whether legacy NA on-highway holds above the Q3'25 trough.
Allison is a two-franchise industrial: (1) legacy automatic transmissions (ALT) leveraged to NA Class 8 / medium-duty / vocational plus a high-margin Defense book, and (2) newly acquired Allison Off-Highway (ex-Dana Off-Highway Drive & Motion) that roughly doubled the revenue base and compressed consolidated Adj EBITDA margin from the high-30s into the mid-20s.
Growth trajectory — acquisition step-change masks a soft legacy organic path.
- Consolidated net sales in Q1 2026 were $1,406M vs $766M in Q1 2025 (+83.6% YoY) — almost entirely Off-Highway. ALT segment sales were only $733M; Off-Highway $673M.
- Pre-deal trajectory was decelerating: Q3 2025 sales $693M were −15.9% YoY vs $824M; Q4 2025 $737M still −7.4% YoY.
- NA on-highway trough was Q3 2025 at $327M (−28.4% YoY); Q1 2026 recovered to $375M but still −13.8% YoY vs $435M. Early trough, not confirmed re-acceleration.
- Defense is the clean growth engine: $87M in Q1 2026 vs $53M (+64.2% YoY); mgmt: “balance of year looks like Q1.”
- Adj EBITDA margin compressed to 25.7% in Q1 from 37.5% a year earlier — mix + PPA, not a sudden legacy collapse. Absolute Adj EBITDA still rose to $362M (+26.1% YoY).
Key watch items into Q2 2026
- Guide hold vs raise — Street models FY26 EBITDA ~$30M above the $1.44B mid. Reaffirm + operational beat = sandbag intact; cut = thesis break.
- Off-Highway sequential step-up — Q1 call flagged Q2 production ramp before EU holiday softness in Q3/Q4. No clean YoY; sequential delivery is the test.
- Defense run-rate continuity — highest-quality earnings stream; any slowdown matters more than Class 8 noise.
- Integration cost creep — pretax integration costs raised from ~$70M to >$100M at Q1.
- EPA 2027 / MD prebuy — explicitly not in the guide; asymmetric upside if color appears.
Classification: CONSERVATIVE guider, mixed GAAP beater, solid Adj beater. Operational beats that do not force guide raises while leverage works from ~3x toward 2x.
Allison guides full-year only (sales, Adj EBITDA, segment sales bands, FCF/capex color). No formal quarterly ranges. The print is judged against (a) the reaffirmed FY26 framework and (b) sell-side quarterly consensus.
| FY2026 guide (reaffirmed Q1'26) | Guide Low | Guide High | Mid | FY25 actual | Read |
|---|---|---|---|---|---|
| Consolidated net sales | $5,575M | $5,925M | $5,750M | $3,010M | +91% reported YoY at mid (acq); organic legacy soft |
| Adj EBITDA | $1,365M | $1,515M | $1,440M (~25%) | $1,130M | +27% YoY mid; ~$30M below ~$1.47B Street |
| ALT (Transmission) sales | $3,025M | $3,175M | $3,100M | n/a (pro forma) | Trough NA truck baked in |
| Off-Highway sales | $2,550M | $2,750M | $2,650M | n/a (owned from 1/1/26) | First full ownership year |
| Off-Hwy synergies in 2026 | $0 | $0 | — | $120M run-rate = 2027 bridge | |
| LT Adj EBITDA margin | 27–29% (multi-year) | 37.5% FY25 legacy | Headline reset post-acq; recovery path is the story | ||
Guide posture: Q1 delivered a ~$10M Adj EBITDA cushion vs Street that was not flowed through — absorbed into higher integration costs (>$100M pretax, was ~$70M). That is textbook sandbagging. Classification = Conservative.
Q2 2026 Street bar (FMP)
| Metric | Q2'25 actual | Q2'26 consensus | Implied YoY | Framing |
|---|---|---|---|---|
| Net sales | $814M | $1,502M | +84.5% | YoY distorted by Off-Hwy; judge vs Q1 $1,406M sequential + Street |
| EPS (Street) | $2.29 act / $2.20 est | $2.48 | +8.3% vs act | Prefer Adj EPS; GAAP still PPA-noisy |
| Adj EBITDA (Street ~) | $313M | ~$518M | +65% vs PY | Implies ~34.5% margin on Street sales — watch mix |
1H bridge: Q1 already printed $1,406M sales and $362M Adj EBITDA. Hitting Street Q2 leaves H2 needing roughly half of the $5.75B mid sales and ~$0.72B EBITDA for the mid guide — achievable if Off-Hwy holds and ALT does not re-trough.
3a. Current quarter drivers (above consolidated)
| Driver | Guide | Q1'26 actual | YoY | Q2 watch |
|---|---|---|---|---|
| Consolidated sales | Not Guided | $1,406M | +83.6% | Street $1.50B; seq step-up expected |
| ALT segment | Not Guided | $733M | ~−4% org. | Hold vs re-trough |
| Off-Highway | Q2 step-up (call) | $673M | n/a | Primary sequential swing |
| NA on-highway | Steady (call) | $375M | −13.8% | Trough was Q3'25 $327M (−28% YoY) |
| Defense | “Like Q1” | $87M | +64.2% | Highest-quality growth |
| Adj EBITDA | Not Guided | $362M | +26.1% | Margin 25.7%; Street ~$518M |
| Adj diluted EPS | Not Guided | $2.57 | +~6% vs adj color | Street $2.48; beat culture on Adj |
| ALT price | ~325 bps FY | ~325 bps Q1 | — | Expected to hold full year |
3b. Eight-quarter trajectory (Daloopa) — YoY growth is the tell
| Metric | Q2'24 | Q3'24 | Q4'24 | Q1'25 | Q2'25 | Q3'25 | Q4'25 | Q1'26 |
|---|---|---|---|---|---|---|---|---|
| Net sales ($M) | 816 | 824 | 796 | 766 | 814 | 693 | 737 | 1,406 |
| Sales YoY % | — | — | — | — | −0.2% | −15.9% | −7.4% | +83.6% |
| Adj EBITDA ($M) | 301 | 305 | 270 | 287 | 313 | 256 | 265 | 362 |
| Adj EBITDA YoY % | — | — | — | — | +4.0% | −16.1% | −1.9% | +26.1% |
| Adj EBITDA margin | 36.9% | 37.0% | 33.9% | 37.5% | 38.5% | 36.9% | 36.0% | 25.7% |
| NA on-highway ($M) | 456 | 457 | 419 | 435 | 417 | 327 | 361 | 375 |
| NA OH YoY % | — | — | — | — | −8.6% | −28.4% | −13.8% | −13.8% |
| Defense ($M) | 43 | 53 | 68 | 53 | 63 | 78 | 73 | 87 |
| Defense YoY % | — | — | — | — | +46.5% | +47.2% | +7.4% | +64.2% |
Interpretation: Legacy sales decelerated through 2025 (Q3 trough −16% YoY consolidated / −28% NA on-highway). Q1'26's +84% sales growth is an acquisition step-function, not organic re-acceleration. The real Q2 tells are: (1) does NA on-highway stay above the $327M trough on a YoY basis that is still negative but less bad, (2) does Defense hold +50%+ YoY, and (3) does Off-Highway deliver the sequential step-up without further margin compression.
3c. FQ+1 and FY+1
- Q3'26: Not Guided. Off-Highway softens Q3/Q4 on European holidays after Q2 ramp (Q1 call).
- FY27 structural: $120M Off-Highway synergy run-rate is the bridge from ~25% to 27–29% Adj EBITDA margin. Zero credit in 2026 guide = sandbag.
Management tone (last 3 transcripts): Confident on Defense and ~325 bps ALT price; guarded on Off-Highway end-market baselines (refused 2025 historical split on Q1 call); deliberate on capital return (buybacks throttled to prioritize ~3x→2x leverage).
Post-guidance updates: No mid-quarter guide change. CAT and CMI print 2026-08-04 — ALSN reports without that same-week OE read-through, so Class 8 / MD commentary is company-specific.
Risks into the print: (1) optical GAAP miss if PPA stays elevated; (2) Off-Highway sequential miss vs “step-up”; (3) further integration cost creep; (4) MD remains “very soft” with no prebuy color.
| # | Catalyst | Timing | Consensus embeds | Our read |
|---|---|---|---|---|
| 1 | Off-Hwy $120M run-rate synergies | 2H'26 onset · Y4 full | $0 in 2026 guide | 2027 step-function if real |
| 2 | Defense multi-program ramp | FY26 | “Like Q1” | Highest-quality growth |
| 3 | NA Class 8 / vocational trough exit | 2H'26–27 | None in guide | Asymmetric if orders inflect |
| 4 | EPA 2027 MD prebuy | 4Q26–1H27 | None in guide | Rule-timing optionality |
| 5 | Delever ~3x → 2x | FY26–27 | Buybacks later | FCF priority first |
| 6 | Integration cost control | Each quarter | >$100M pretax | Watch creep vs guide |
| Date | Headline | Source | Commentary |
|---|---|---|---|
| 2026-05-04 | Q1 results; FY26 guide reaffirmed | PR / IR | Operational beat, optical GAAP miss, sandbag intact |
| 2026-07-20 | Q2 earnings call set for Aug 3, 5 p.m. ET | IR | Confirms print window |
| Ongoing | Intl defense platforms (K9, Borsuk, Kaplan, India FICV) | Call color | Multi-year booking story |
| Industry | Class 8 vocational steadier than MD | Trade press | Matches “pockets of strength” language |
| Rev act vs est | EPS act vs est | Magnitude / read | |
|---|---|---|---|
| Q2'25 | $814M vs ~$799M (+1.9%) | $2.29 vs $2.20 (+4.1%) | Clean double beat |
| Q3'25 | $693M vs ~$719M (−3.6%) | $1.63 vs $1.95 (−16.4%) | Demand-driven double miss at trough |
| Q4'25 | $737M vs ~$725M (+1.6%) | $1.18 vs $1.56 (−24.4%) | Rev beat / EPS miss |
| Q1'26 | $1,406M vs ~$1.38B (+2.9%) | GAAP $1.33 vs $2.07; Adj $2.57 | Optical GAAP miss; Adj / EBITDA beat |
Pattern: L4Q GAAP EPS mixed (~1–2/4 beats); operational Adj metrics ~75% multi-year beat rate. Q3'25 was the clean demand-driven double miss. Post-acquisition, judge Adj EBITDA and Adj EPS, not GAAP, until PPA normalizes. Beat magnitude on Adj is often +5–15%; Q1'26 Adj was ~+$0.15 vs ~$2.42 street adj color.
Into Aug 3: Bar is Street $1.50B / $2.48. Base case = operational beat + guide reaffirm. Raise = positive surprise. Cut = narrative break.
| Scenario | What it looks like | Fundamental implication |
|---|---|---|
| Bull | Rev/Adj beat + Defense strong + synergy $ in 2H language + guide raised | 2027 synergy story pulled forward; sandbag broken upward |
| Base | In-line / slight beat + guide reaffirm + Off-Hwy step-up confirmed | Sandbag intact; own for 2027 + Defense duration |
| Bear | Off-Hwy sequential miss + integration cost up again + soft Defense | Deal narrative de-risked lower until 2027 proof |
Bottom line: Setup is sandbag-biased into a low-drama industrial print. The investment case is 2027 synergy + Defense duration, not a Q2 fireworks print. Force the call on Off-Highway end-market disclosure and any EPA'27 prebuy language — those are the asymmetric tells.
