Lumentum’s Revenue More Than Doubles as AI Optics Demand Delivers a Record Quarter — and a Bigger Guide
Lumentum Holdings, the laser and optical-components maker that has become one of the market’s purest plays on AI data-center plumbing, reported fiscal fourth-quarter revenue of $1.01 billion after Tuesday’s close, more than doubling from $480.7 million a year earlier and topping the roughly $985 million analysts expected, according to Investing.com’s earnings coverage.
Profitability ran even further ahead of the top line. Adjusted earnings came in at $3.23 per share against a $2.95 consensus, per Investing.com, while adjusted gross margin expanded to 50.4% from 37.8% a year earlier and adjusted operating margin more than doubled to 36.6% from 15.0%. Both of the company’s segments participated: components revenue rose 103% year over year to $649.4 million and systems revenue climbed 123% to $356.9 million.
The guidance was arguably the bigger headline. Lumentum forecast fiscal first-quarter revenue of $1.225 billion to $1.275 billion — a midpoint of $1.25 billion versus the $1.16 billion consensus — with adjusted earnings around $4.20 per share at the midpoint, far above the $3.63 analysts had modeled, and an operating margin of 39.5% to 40.5%, per Investing.com. Coverage from Congress.net noted the outlook would bring Lumentum to its target operating model more than a quarter ahead of schedule.
“As AI compute workloads increase in both speed and bandwidth, data center architects are turning to optical links as a primary means of connectivity,” chief executive Michael Hurlston said, according to Investing.com. Congress.net reported Hurlston singled out 200-gigabit externally modulated lasers, 1.6-terabit optical transceivers, optical circuit switches and ultra-high-power lasers for co-packaged optics as products now essential to AI infrastructure deployments.
The report carried unusual weight because of how far the stock had already run. Shares closed Tuesday around $817 ahead of the release, and 24/7 Wall St. framed the print as a test of whether a roughly 600% one-year rally could continue. Options markets were pricing an implied move of about 13% through Friday, a preview from ts2.tech noted — yet the initial after-hours reaction was strikingly calm, with the stock trading nearly flat, per Investing.com.
That muted response suggests a market that had largely front-run the beat. Lumentum’s forward earnings multiple sat near 99 times into the report, per ts2.tech, and Monday’s selloff in fellow photonics name Coherent — driven by a social-media debate over whether optics or memory is the better AI trade — showed how quickly sentiment in the group can turn even without bad news.
For the mid-cap universe it recently graduated from, Lumentum’s quarter is the season’s clearest evidence that AI infrastructure spending is still accelerating down the supply chain. The company ended the quarter with $2.7 billion in cash and short-term investments, per Investing.com — and with Coherent reporting Wednesday, the optics trade gets its next referendum in less than 24 hours.
