That wraps up our initial coverage of Lumentum’s Q4 results. Thank you for stopping by!
Lumentum delivered a breakout fiscal Q4, with revenue surging 109.3% year over year to $1.006 billion. Adjusted EPS climbed from $0.88 to $3.23, while non-GAAP gross margin expanded by 1,260 basis points to 50.4%, and operating margin more than doubled to 36.6%.
CEO Michael Hurlston said Lumentum is “positioned at the heart of a secular industry shift” as rising AI computing speeds and bandwidth requirements push data center operators toward optical connectivity.
The company reported momentum across optical circuit switches, 1.6T cloud modules, and initial orders for ELS modules and ultra-high-power co-packaged optics lasers.
Management expects the growth to accelerate, guiding for fiscal Q1 revenue of $1.225 billion to $1.275 billion and adjusted EPS of $4.05 to $4.35.
The $1.25 billion revenue midpoint would represent roughly 24% sequential growth and allow Lumentum to reach its target operating model more than one quarter ahead of schedule.
Lumentum recorded a $7.2 billion GAAP net loss, but that figure primarily reflected a one-time, non-cash $7.8 billion debt-extinguishment charge rather than deterioration in the underlying business.
Lumentum just reported earnings, with shares initially down 2% following the report. Here are the key numbers:
Quick Read:
Lumentum beat Wall Street’s revenue and earnings expectations, but shares initially moved lower.
Revenue soared 109% year over year and 24% sequentially, reflecting continued momentum across the business.
Beyond the headline guidance, four wildcards could swing tonight’s reaction on Lumentum (NASDAQ:LITE).
Options positioning skew. The full-chain put/call ratio sits at 1.08, but the September 4 expiration spikes to 11.01, signaling institutional hedging into the post-earnings window.
Insider selling. Despite bullish social sentiment scoring 78, insiders logged 22 recent transactions, net selling, a caution flag consensus is discounting.
OCS ramp execution. The optical circuit switch backlog above $400M requires flawless manufacturing scale-up, and product mix shifts have historically materially impacted profitability quarter to quarter.
Trade and tariff exposure. Export controls, ongoing Huawei bad-debt exposure, and ASP compression are outside sell-side models targeting $1,125.93.
Lumentum enters tonight’s earnings report with management guiding for record quarterly revenue of $960 million to $1.01 billion.
The company also expects an operating margin of 35-36%, which would mark another improvement from 32.2% in Q3.
Investors will be watching for updates on Lumentum’s emerging co-packaged optics and optical circuit switch businesses, which are expected to become important fiscal 2027 growth drivers.
The report will provide a major credibility check on CEO Michael Hurlston’s $2 billion quarterly revenue target and his projection that co-packaged optics could create “greater than $5 billion of incremental revenue.”
With NVIDIA’s $2.02 billion investment now on the balance sheet and additional Greensboro capacity expected in 2028, Lumentum must show that its 600%+ one-year rally is being supported by accelerating fundamentals.
Live coverage has ended. The full story is below.
Lumentum Holdings (NASDAQ:LITE | LITE Price Prediction) reports Q4 FY2026 earnings after the close today at 4:00 PM ET. With shares up over 600% in the past year driven by AI optical demand, expectations heading into earnings are extraordinarily high.
Last quarter, Lumentum delivered revenue of $808.4 million, up 90.12% year over year, and non-GAAP EPS of $2.37, beating by 4.62%. Systems revenue climbed 121.1%, and non-GAAP operating margin expanded 700 basis points sequentially to 32.2%.
Despite the beat, shares slipped 5.06% on the print, a signal that expectations had run ahead of the numbers. The stock now trades around $816.56, off from a post-Q3 peak near $1,013. Full-chain put/call sits at 1.14, tilted defensive.
| Metric | Q4 FY26 Estimate | YoY Change | FY26 Implied | Q4 Guide Range |
|---|---|---|---|---|
| Revenue | $987.7M | +105% | ~$2.99B | $960M-$1.01B |
| EPS (Non-GAAP) | $2.9689 | +237% | ~$8.11 | $2.85-$3.05 |
Consensus sits near the midpoint of guidance, leaving no cushion. The sequential jump from 32.2% operating margin to 35% requires continued pricing discipline and mix tailwinds.
Tonight, I’ll be watching whether gross margin, at 47.9% last quarter, expands further. CEO Michael Hurlston has previously said “there is a lot of room for improvement on gross margin,” driven by better factory absorption and pruned product lines.
I’ll all focus on the EML supply-demand gap Hurlston pegged at “somewhere greater than 30%,” and the plan for supply to “increase 50% on year” by the December quarter.
Analysts will be tracking the pump laser capacity out of Rose Orchard. Hurlston called constraints there “probably the biggest issue,” with narrow linewidth assemblies “effectively sold out for the foreseeable future.”
Investors will be looking for updates on the multi-hundred-million-dollar CPO purchase order for the first half of calendar 2027 as well as the OCS ramp against a backlog exceeding $400M. Finally, watch for new long-term agreements with prepayments or take-or-pay terms tied to CapEx.
| Quarter | EPS Surprise | 1-Day Move | 7-Day Move | 30-Day Move |
|---|---|---|---|---|
| Q3 FY26 | +4.62% | -5.48% | +9.12% | -5.18% |
| Q2 FY26 | +18.57% | +8.35% | +23.32% | +37.62% |
| Q1 FY26 | +7.05% | +2.98% | +9.05% | +47.18% |
| Q4 FY25 | -12.88% | -4.67% | -3.61% | +40.37% |
On average, shares moved +11.21% seven days after earnings over the past year.
