Q1 vs FY Guide Arithmetic Coherence Check

When a company's Q1 revenue guide, if achieved, makes the full-year guide arithmetically implausible, the FY guide is almost certainly a floor — not a base case. The coherence test: take the Q1 midpoint guide, subtract from FY midpoint guide, divide by 3 to get implied average for Q2–Q4. If that implied quarterly run-rate is dramatically below the recent sequential trend with no supporting evidence of a structural slowdown, the FY guide is sandbagged. This can be detected at time of issuance, before any actuals confirm it.

Evidence

• HNGE FY26: Q1 guide midpoint $172M (implied 39% YoY), FY guide midpoint $737M (implied 25% YoY). Remaining three quarters would need to average only $188M — a 5M/quartersequentialadd, vsFY25averageof 12M/quarter. H2 FY26 would need to decelerate to ~17% YoY from 45% in Q4 FY25. No leading indicator (yield expansion, record win rates, non-ASO +130% YoY, CMS pipeline) supports this deceleration. Management also baked in flat yield, flat ASP, and zero revenue from new channels as explicit assumptions — a trifecta of maximum conservatism.
• This differs from the consistent-beat-magnitude pattern (which requires historical beat data to calibrate). The arithmetic incoherence signal works at first earnings report, or for any newly public company, with only Q1 guide + FY guide in hand.

Implication

Add a coherence screen to every guidance assessment: (1) compute implied Q2–Q4 average from FY guide minus Q1 guide; (2) compare to recent quarterly sequential trend; (3) if the implied H2 requires deceleration of >15pp with no structural justification, treat FY guide as floor and build a bear/base/bull scenario. Bear = FY guide. Base = Q1 extrapolation with modest conservatism. Bull = Q1 guide + beat factor from consistent-beat-magnitude insight. This screen is especially powerful for newly public companies (short beat history) and when management explicitly layers conservative assumptions (flat yield, flat ASP, zero from new channels).
