Coherent's lasers power the AI data-center buildout, an infrastructure play that keeps running and a stock to hold through the next cycle. x.comÂ

Coherent is a structural bet on the data center shift from chips to connectivity, where optical components are now the bottleneck. Hyperscaler capex is forecast up 36% in 2026, and AI infrastructure spending is strategic necessity that won't be deferred in a recession. Nvidia's $2 billion investment locks in optical supply and gives Coherent revenue visibility through the decade. Its S&P 500 inclusion comes while the market prices a recession, setting up a repricing over the next 12 months. … Show more
Coherent's 6-inch substrate access, yields and margin concerns look mostly like timing issues in the optical buildout. Coherent is now one of the preferred ways to gain exposure and should participate meaningfully, despite those constraints. x.comÂ
Coherent and Lumentum are ultra overvalued, so when their monthly top comes in, they should fall about four times faster than they rose. Coherent may have already topped. x.comÂ
Coherent is becoming the gatekeeper of AI photonics as networking hardware grows as critical and scarce as GPUs. It is the only player to move to 6-inch InP wafers, more than doubling chips per wafer and giving it a cost edge over rivals that buy laser chips, with EML and CW laser capacity set to double in 2026 and again in 2027. Its liquid-cooled XPO optics cut TCO by 20-30%, and its briefing raised its 2030 addressable market to $70B+, including $15B+ for CPO/NPO. x.comÂ
Coherent is positioned as photonics becomes a national priority for AI data centers. Its lasers and optical components move data between chips fast enough to keep up with AI workloads. Nvidia invested billions directly in Coherent and Lumentum this year, and integrated photonics was just added to the White House priority list as a brand-new category, so Nvidia bought in ahead of the government's call. x.comÂ
Coherent is a solid, profitable long over the next year, with 50-100% gains reasonable though probably not 200%. Like Marvell, it is a "they do everything" semiconductor company whose business few people can describe, the Deloitte of semis. x.comÂ
Coherent is a tactical buy because growth and margins should accelerate once its 6-inch production ramps, yield challenges notwithstanding. The quarter disappointed on a slower 2x InP ramp and slow margin progress toward 42%, with Coherent still reliant on Lumentum's lasers. Over the next 4-8 quarters it can catch up in simpler CW lasers, with OCS and CPO the real upside. Lumentum, growing about 90% versus Coherent's 20%, remains the preferred concentrated long-term AI-optics bet. x.comÂ
Coherent has the most substance in the optical group and the only real base on its chart, while the sector's sell-off is macro, not fundamental. At about 23x 2027 estimates it looks mispriced, and it is the only company holding 6-inch InP, silicon photonics, OCS and CPO engines at once. It alone has stopped making lows. Rate-hike pricing and a 5.04% 10-year are still compressing optical multiples, so staged, defined-risk entries beat full commitments; a daily close below 264 invalidates it. … Show more
AI bandwidth demand still favors Coherent and Lumentum, but tight customer financing can delay orders and lasting valuations need durable profits. A model provider losing share need not reduce total bandwidth use. Coherent could beat and raise guidance; Lumentum may only meet estimates this quarter, improving next quarter. If margins partly reflect scarce indium phosphide, added supply will test whether upgrades, volume and cost gains sustain earnings. These earnings calls remain forecasts. … Show more
Coherent now has credible exposure to almost every optical architecture hyperscalers are exploring, and its Nvidia deal materially de-risks that roadmap. Nvidia's nonexclusive pact adds a multibillion-dollar purchase commitment, a $2B equity investment and access to five CPO product families. First CPO/NPO revenue targeted for H2 2026 matches Nvidia's timing. Data center and communications are already 72% of revenue. Qualification, standards, concentration and margins remain unsettled. x.comÂ
