Postmortem
TL;DR
Marvell’s Q3 FY26 print broadly matched the bullish earnings preview:
- The company delivered a clean beat on EPS and revenue, with AI data-center strength front and center.
- Guidance came in better than “just inline”, with management sounding confident about the next couple of years of AI-driven demand.
- At the stock level, MRVL jumped about 7–8% from the pre-earnings close to the next session’s open/close, a solid move but smaller than the ~12% one-day move implied by the front-week straddle.
- The concurrent announcement of the Celestial AI acquisition added a new strategic pillar but also injected some deal-risk debate.
Directionally, the call for a beat and an upside reaction was correct. The main miss was on magnitude: realized upside was respectable, but did not fully match the 9% “central case” and came in well below the 12% implied move.
What Actually Happened
Results vs expectations
Q3 FY26 landed clearly in “beat” territory:
- Non-GAAP EPS printed above consensus, with operating leverage from the AI data-center ramp.
- Revenue came in slightly ahead of Street estimates, driven by data-center and AI custom silicon while other segments remained more mixed.
- Year-on-year revenue growth stayed in the mid-30s percent range, consistent with the AI-acceleration narrative rather than a one-off spike.
Relative to the preview, this lined up with the expectation that headline numbers would not be the problem; the Street was more focused on guidance, AI trajectory, and deal optics.
Guidance tone
Guidance was the real swing factor and it came in better than the “inline” stance baked into the preview:
- Management pointed to continued strength in AI-related data-center demand over the next couple of years, with commentary that implied a healthy runway rather than near-term exhaustion.
- The outlook for the next quarter and beyond was framed with constructive language on AI ramps, while acknowledging lumpiness in legacy or non-AI areas.
- The overall message felt closer to “strong” guidance than a cautious “just enough” update.
This was the key area where reality modestly exceeded the preview’s “inline” guidance expectation and helped support the upside gap.
Celestial AI deal
The other major development was the definitive agreement to acquire Celestial AI, a photonics startup focused on scale-up optical interconnects for next-gen AI and cloud data centers.
Key implications:
- Strategically, the deal deepens Marvell’s AI/data-center stack, positioning the company as a more integrated provider of high-bandwidth optical links into custom accelerators and XPUs.
- Financially, the size and structure of the transaction framed Celestial AI as a meaningful long-term growth driver, with earn-out milestones tied to ambitious revenue targets.
- Near-term, investors had to digest a multi-billion-dollar deal on top of an already rich AI narrative, which likely tempered how far the stock could run on the earnings beat alone.
In the preview, the M&A chatter was flagged as a risk: the fear was that expensive or fuzzy deal terms could overshadow a good quarter. In practice, the market’s initial reaction appeared to be cautiously positive—seeing the deal as strategically logical, even if the final verdict will depend on execution.
Price Action vs the Call
Using the canonical amc framework:
- Prev close (report day): about $92.89
- Next regular-session open: about $100.04
- Next regular-session close: about $100.20
That translates to:
- Earnings gap return: roughly +7.7% from report-date close to next open.
- Earnings session return: roughly +7.9% from report-date close to next close.
The preview’s directional call was:
- Direction: up
- Expected move magnitude: about +9%
- Directional confidence: 0.60
In practice:
- Direction was correct: the stock gapped and closed higher in the post-earnings session.
- The magnitude came in a bit lighter than the 9% central case and significantly below the ~12% move priced by the front-week straddle.
From an options perspective, that outcome favored:
- Traders who sold event vol (iron condors, calendars, diagonals) over those who paid full freight for the front-week straddle.
- Directional bulls who used defined-risk call spreads rather than naked calls or lottos.
How the Options & Tape Setup Aged
The preview highlighted a few key features of the tape:
- Front-week ATM IV around the mid-100s, with a 12% implied move into the event.
- A call-tilted front-week and near-term OI profile, signaling hedged bullishness.
- Meaningful downside put demand at strikes just below spot, reflecting respect for another “August-style” disappointment.
- Strong call interest and OI further out (e.g., December and mid-’26 strikes), consistent with a structurally bullish AI story.
Postmortem, that read holds up reasonably well:
- The directional bias embedded in the chain — modestly bullish but hedged — matched the realized outcome: a solid upside gap but no blow-off move.
- The front-loaded IV did prove expensive in hindsight: realized volatility around the event was lower than what the straddle implied, so sellers of pure event vol had the edge.
- Longer-dated call interest still looks reasonable given:
- A confirmed AI revenue ramp,
- Strong guidance tone,
- And a strategic optical interconnect acquisition that can leverage hyperscaler demand.
The main takeaway: the options market correctly sniffed out an upside bias, but overpaid for the tail relative to the actual move.
Where the Preview Was Right (and Wrong)
What held up
-
Beat vs consensus
The preview framed Q3 as a likely fundamental beat on both EPS and revenue, driven by AI data-center strength. That’s exactly what played out. -
Directional call (up)
The view that the stock would move higher on a decent quarter and non-disastrous guidance was validated by the 7–8% post-earnings jump. -
Characterization of positioning
The chain was described as hedged-bullish — call-heavy, but with substantial downside protection. The post-earnings reaction fits that setup: an upside move big enough to reward bulls, but not so violent that it looked like everyone was offsides. -
Framing of risks
The preview emphasized:- Guidance tone,
- The possibility of another “August-style” sentiment shock,
- And the new Celestial AI M&A overhang.
In reality, those were exactly the areas investors focused on — they just landed more positively than feared.
Where it missed
-
Move magnitude
The central case of ~9% upside vs a 12% implied move ended up slightly overstating realized volatility. The stock did rally, but the move was closer to 8% at the open/close rather than 9–12%. This matters for traders sizing straddles, strangles, or wings. -
Guidance characterization
Guidance was tagged as “inline expected” going in, with the Street not counting on a heroic raise. Actual guidance and tone came through as stronger than that baseline, which helped reinforce the upside despite already-elevated expectations. -
M&A drag vs lift
The preview leaned a bit more toward the risk that Celestial AI deal terms could weigh on the reaction. Early market response suggests investors saw the transaction as more of a strategic accelerator than a reckless overpay, at least for now.
How the Suggested Trade Framework Would Have Fared
The preview sketched out a few broad trade ideas. In light of what actually happened:
1. Defined-risk upside via front-week call spreads
Conceptually: long 12/05 near-ATM call, short higher-strike call (e.g., 93/100 or 95/105).
- With a ~7–8% post-earnings pop, bull call spreads anchored near spot would have worked reasonably well, especially if upper strikes were around the high-90s/low-100s.
- Because the move undershot the implied 12%, spreads likely captured a good chunk of intrinsic value without being overly exposed to event IV crush.
Verdict: Directionally effective, and more efficient than naked long calls, but still exposed to rich vol pricing.
2. Calendars/diagonals to sell rich event vol and buy time
Structures that sold 12/05 premium and owned later-dated calls fared well in this outcome:
- The front-week IV collapsed as expected after earnings, and because the move was significant but not explosive, short front-week options likely decayed nicely.
- Longer-dated calls retained decent value thanks to the upward price shift and stronger medium-term AI story.
Verdict: One of the cleaner ways to monetize the “rich event vol / moderate move” mismatch.
3. Downside hedges and put spreads
Protective put spreads around the mid-80s or lower were not needed this time:
- They provided insurance that ultimately expired with little or no intrinsic value, consistent with the view that downside risk was real but not realized this quarter.
- For long-only holders, the “wasted” hedge premium can still be justified by the size of the implied tail and the August playbook.
Verdict: Costly but not irrational insurance in a name that still has a history of double-digit earnings gaps both ways.
Lessons for Future MRVL- and AI-Style Setups
-
Strong AI narrative + rich implied move doesn’t guarantee a blowout
Even with a beat, strong guide, and strategically sound M&A, the stock only moved high single digits. Once AI optimism is widely held, there’s a limit to how much incremental good news can move the needle in one shot. -
Event vol can stay too high even when direction is right
The chain correctly flagged upside odds, but still overpriced the magnitude. For similar cases — AI leaders with strong positioning and big implied moves — calendars, diagonals, and spreads may be better than naked long gamma. -
M&A overhangs are nuanced, not purely bearish
The Celestial AI deal shows that a sizeable acquisition in the AI stack can be taken as validation of a long-term strategy rather than just a near-term EPS drag, especially when structured with performance-based earn-outs. -
Guidance “inline vs strong” matters more than small EPS beats
The Street largely assumes Marvell will beat the quarter; the swing factor is how management frames the next 1–2 years of AI demand. Small differences between “inline” and “strong” guidance can be the difference between a flat close and a high-single-digit pop.
Bottom Line
For Q3 FY26, Marvell delivered exactly the kind of AI-driven beat that the preview anticipated, coupled with better-than-feared guidance and a high-profile acquisition that deepens its AI data-center story.
The directional call (beat and up) was validated, and the 7–8% post-earnings jump was a respectable outcome in a name that had a 12% implied move baked into the front-week options.
For traders, the quarter reinforces a familiar pattern in high-expectation AI leaders:
- Directional skew can be right,
- Event vol can still be too expensive, and
- The best risk/reward often sits in defined-risk spreads and vol-selling overlays, not in paying full price for the straddle.
