Lumentum Holdings Inc. (NASDAQ:LITE) is one of the best AI networking stocks to buy according to analysts. On June 11, JPMorgan reiterated an Overweight rating on the stock and maintained its price target after a recent pullback in optical networking names. The firm argued that investor concerns around co-packaged optics adoption were overdone, a useful signal for a company increasingly tied to the optical layer of AI data centers.
The bull case has also been supported by Lumentum’s operating momentum. On May 5, the company reported fiscal third-quarter 2026 revenue of $808.4 million, up 90.1% year over year. Non-GAAP operating margin expanded to 32.2%, while non-GAAP diluted earnings per share rose to $2.37 from $0.57 a year earlier. Management said strength in laser chips and scale-across components helped the quarter, and pointed to co-packaged optics and optical circuit switches as future drivers of earnings power.
Lumentum Holdings Inc. (NASDAQ:LITE) is an optical and photonic technology company headquartered in San Jose, California. Its lasers, modules, and optical subsystems support AI infrastructure, cloud computing, data center connectivity, telecom networks, industrial manufacturing, and sensing applications.

Four leading AI models discuss this article
"Lumentum's valuation is currently pricing in a seamless transition to next-gen optical architectures, ignoring the significant execution risk and potential margin cannibalization inherent in that shift."
Lumentum’s 90% revenue growth is impressive, but it masks a high-beta dependency on hyperscaler capex cycles. While the JPMorgan reiteration provides a floor, the 'co-packaged optics' (CPO) narrative is a double-edged sword. If CPO adoption accelerates, it could cannibalize Lumentum’s traditional pluggable transceiver business faster than their new product lines can offset the margin compression. With a non-GAAP operating margin of 32.2%, the company is priced for perfection. Any deceleration in AI cluster build-outs—or a shift in architectural preference toward proprietary interconnects—will see the P/E multiple compress rapidly, as the market currently treats LITE as a pure-play infrastructure winner rather than a cyclical component supplier.
If Lumentum successfully pivots to become the primary supplier for next-gen optical circuit switches, their moat will widen significantly, rendering current valuation concerns moot as they capture a larger share of the data center power budget.
"LITE's bull case hinges entirely on co-packaged optics becoming a standard hyperscaler architecture within 24 months—a binary outcome the article treats as settled when it remains contested."
JPMorgan's reiteration matters tactically but masks a structural question: LITE's 90% YoY revenue growth and 32.2% operating margins are real, but they're built on a narrow bet—co-packaged optics adoption. The firm claims investor concerns are 'overdone,' yet provides no new data. LITE trades on the assumption that CPO becomes standard in hyperscaler data centers within 2-3 years. If adoption stalls (due to cost, thermal complexity, or incumbent resistance from traditional transceiver makers), the multiple compresses hard. The article also soft-pedals that LITE faces cyclical capex risk: hyperscalers can pull forward or defer optical spending. JPMorgan's Overweight is reassuring but not a fundamental catalyst—it's defensive positioning after a pullback.
LITE's valuation likely already prices in significant CPO adoption; JPMorgan's note is backward-looking comfort, not forward guidance. If co-packaged optics face real engineering or cost headwinds in production, consensus will reverse sharply and the stock has 40%+ downside.
"LITE's valuation already embeds flawless optical AI adoption that remains unproven beyond the current spending cycle."
JPMorgan's maintained Overweight after the pullback signals that co-packaged optics fears are premature, yet the 90% YoY revenue surge to $808M and 32% margins rest heavily on a handful of hyperscale customers accelerating AI builds. The article downplays execution risk around optical circuit switches and ignores how quickly ASP erosion or delayed ramps could compress the 2.37 non-GAAP EPS. Forward multiples already price in sustained 50%+ growth; any 2025 capex digestion would trigger re-rating. LITE remains a leveraged AI infrastructure play whose visibility is shorter than management implies.
The same customer concentration that creates downside also delivers durable pricing power if AI training clusters keep scaling through 2026, validating the current multiple.
"Lumentum’s upside rests on a durable AI-optics capex upcycle; any deceleration in hyperscaler demand or delay in co-packaged optics adoption could erode earnings power and trigger multiple compression."
The JPMorgan push supports LITE as a lever to the AI optical layer and lends credence to a margin-up cycle, but the bullish thesis hinges on durable co-packaged optics adoption and sustained hyperscaler capex. The May 2026 results showed impressive growth and margins, yet that could reflect a near-term AI spending spike rather than a lasting cycle. The article omits risks like intense competition in optics, potential supply-chain or tariff headwinds from onshoring, and the possibility that AI workloads plateau, slowing demand. If capex cools or co-packaged optics adoption stalls, LITE’s growth and valuation could disappoint despite the current optimism.
Against the view, AI capex cycles are volatile; co-packaged optics adoption remains unproven at scale, and the stock could be priced for a longer, uncertain ramp rather than a durable upcycle.
"Lumentum faces structural margin compression from the commoditization of laser sources in silicon photonics, independent of CPO adoption timelines."
Grok and Claude are fixated on CPO cannibalization, but you are all missing the 'optical engine' transition. Lumentum isn't just a transceiver shop; they are pivoting to high-density laser arrays. The real risk isn't CPO adoption—it's the commoditization of the laser source itself. If hyperscalers shift to silicon photonics platforms where the laser is a discrete, interchangeable component, Lumentum’s margins will face structural pressure regardless of whether CPO succeeds or fails. This is a margin-floor risk, not a growth-ceiling risk.
"Margin compression from growth normalization (2025-2026) is a higher-probability risk than long-term silicon photonics commoditization."
Gemini's silicon photonics risk is real but premature. Hyperscalers aren't shifting to discrete laser components yet—CPO adoption itself requires integrated photonics, not commoditized lasers. The actual margin floor risk is 18-24 months out, not immediate. What nobody's flagged: Lumentum's 32% operating margin assumes 90% growth sustains through 2026. If growth normalizes to 30-40% YoY by Q4 2025, operating leverage reverses and margins compress 300-500bps before any silicon photonics threat materializes. That's the nearer-term re-rating catalyst.
"Silicon photonics commoditization could accelerate margin compression exactly when growth normalizes, exposing LITE to faster downside."
Claude's timeline for margin compression assumes silicon photonics stays distant, yet Lumentum's laser array pivot could face commoditization pressure exactly when growth slows to 30-40%. If hyperscalers standardize discrete lasers amid selective AI capex, the 32% operating margin erodes faster than 300-500bps, with ASP declines hitting before any CPO ramp validates the multiple. This intersection creates a nearer-term re-rating trigger than flagged.
"The real risk is silicon photonics/laser-on-chip commoditization pressuring laser-array margins, causing ASP erosion and faster margin compression than CPO cannibalization alone."
Gemini argues commoditization risk; I’d push a different angle: the bigger, under-discussed threat is the silicon photonics/laser-on-chip trend that could commoditize LITE’s laser arrays even if CPO scales. If hyperscalers lean toward modular but standardized laser sources, LITE’s margin expansion becomes contingent on CPO adoption and high-volume laser pricing staying elevated—both uncertain. The near-term risk is ASP erosion and faster margin compression than the article implies, not just CPO cannibalization.
The panel is bearish on Lumentum, with key concerns being the potential commoditization of laser sources due to silicon photonics, the risk of margin compression as growth normalizes, and the uncertainty around co-packaged optics adoption.
