1. Setup Recap
AeroVironment reported after the close on Tuesday, Dec. 9.
The pre-earnings call was for a down gap (~-11%) with medium confidence (60%), expecting a miss with weak forward commentary.
2. What Actually Happened
Headline mix was “record sales, margin/cost pain”:
- Adj. EPS: $0.44 vs $0.78 expected.
- Revenue: $472.5M vs ~$469M expected.
- Outlook: FY revenue $1.95B–$2.0B and adj. EBITDA $300M–$320M, broadly in-line with Street framing.
3. Price Action
- Prior close (Tue): $281.42
- Open (Wed): $266.25 → -5.4% gap
- Close (Wed): $245.25 → -12.9% close-to-close
No reversal — selling pressure intensified into the close.
4. Attribution: Why It Moved
The tape cared more about earnings quality than the revenue print:
- The quarter had record revenue, but profitability was pressured (acquisition-related amortization/non-cash purchase accounting expenses were a visible drag).
- Guidance didn’t offer a “save” — it read as not meaningfully better than what investors already had priced.
- After a strong year, the stock acted like a de-risking / profit-taking candidate when EPS missed badly.
5. What Worked / What Didn’t
What worked:
- Directional call (down) was right on both the gap and the close.
- The miss focus captured the dominant investor reaction.
What didn’t:
- The setup expected weak guidance; instead, the guide was closer to in-line — the selloff was still driven by earnings quality/costs.
6. Lessons & Playbook Updates
- For acquisitive defense tech stories: if EPS is the swing factor, treat integration + purchase accounting drag as a first-order risk to the print.
- “Record revenue” won’t protect a richly-performing stock when EPS misses by a lot and guidance doesn’t reset higher.
