SAN JOSE, California, April 26, 2026, 10:04 PDT
Lumentum Holdings Inc. heads into a key earnings week with its stock still riding one of the market’s sharpest artificial-intelligence infrastructure trades, after shares last changed hands Friday at $881.64, up 4.1%. U.S. markets were closed on Sunday, leaving investors to weigh a fresh ownership filing and a May 5 earnings report.
The timing matters. Lumentum said it will report fiscal third-quarter results after the market closes on Tuesday, May 5, with a webcast set for 2 p.m. Pacific time. For a stock priced on AI data-center demand, that report is now less about whether demand is strong and more about how much of it can turn into shipped product, margins and guidance.
BlackRock Inc. filed an amended Schedule 13G/A on Friday showing beneficial ownership of 5,240,774 Lumentum shares, or 7.3% of the class, with sole voting power over 4,893,942 shares. A Schedule 13G is a U.S. filing used by passive investors that cross major ownership thresholds, so it is not the same as an activist stake, but it gives the market a current look at a large holder’s position.
Analysts have been raising the bar. MarketBeat reported Friday that Needham lifted its Lumentum price target to $1,040 with a “buy” rating, while Mizuho raised its target to $930 and TD Cowen lifted its target to $875 but kept a “hold” rating. The same report showed one Strong Buy, 10 Buy and seven Hold ratings on the stock. MarketBeat
The bull case is simple and not small. Lumentum sells optical and photonic parts used to move data quickly inside and between data centers, a bottleneck that has become more urgent as cloud companies build larger AI systems. Needham analyst Ryan Koontz called Lumentum the firm’s 2026 “pick of the year” in a Feb. 4 report, Investor’s Business Daily wrote in a piece published two days ago. Investors.com
Chief Executive Michael Hurlston gave investors a stronger version of that case earlier this month. Demand from major U.S. tech companies was on track to fill order books through 2028, he told Bloomberg, adding that Lumentum was “falling further and further behind the demand.” Hyperscalers means the large cloud operators that build massive computing networks.

Lumentum’s last quarterly report showed why the market latched on. The company posted fiscal second-quarter revenue of $665.5 million, up 65.5% from a year earlier, and non-GAAP diluted earnings per share of $1.67. Hurlston said the company was “only at the starting line” for optical circuit switches, or equipment that routes light signals through a network, and co-packaged optics, which puts optical connections closer to chips to move data with less power.

The Nvidia link is the other anchor. Nvidia announced in March a multiyear strategic agreement with Lumentum that included a $2 billion investment, a multibillion-dollar purchase commitment and capacity access rights for advanced laser components. Nvidia CEO Jensen Huang said the two companies were working on silicon photonics for “gigawatt-scale AI factories.” Lumentum Investor Relations
Capacity is still the hard part. Lumentum said in March it would set up a 240,000-square-foot manufacturing site in Greensboro, North Carolina, to make indium phosphide, or InP, optical devices used in high-performance lasers. The site is expected to ramp production in mid-2028, with Nvidia as a customer of the facility.
The competitive field is getting more attention too. Reuters reported in March that Lumentum and Coherent, another photonics products maker, were set to join the S&P 500 alongside Vertiv and EchoStar, a move that typically forces index-tracking funds to buy shares and raises market visibility. Coherent is the cleanest peer comparison because it also sells optical technology into AI and data-center infrastructure.
But the setup leaves little room for a soft guide. Lumentum said in an April 8 filing that it would deliver about 5.7 million common shares in exchange for roughly $264.8 million of 2026 convertible notes and $209.8 million of 2029 convertible notes, with incremental dilution of about 0.6 million shares tied to principal amounts. If AI orders slip, capacity arrives late or margins lag, that dilution and the stock’s valuation could matter more quickly.
For now, the next clear test is May 5. Investors will be looking for evidence that Lumentum can keep converting AI optics demand into revenue without losing pricing power, while showing that its manufacturing buildout can catch up with the market’s expectations.
