Optical components and laser systems supplier — Coherent (post the II-VI / Coherent merger) is the diversified optical platform that captures the AI datacom ramp through 800G/1.6T transceivers, indium-phosphide lasers, and the SiC/photonic-IC layer. Q3 FY26 (May 6) was a revenue beat with a modest EPS miss — the kind of "good but not perfect" print that gets a +400% one-year stock to consolidate, not crash. Tier B because the rerating has been violent (+400% TTM) and the EPS miss tells you the operating leverage is not yet bulletproof; needs one more clean print before earning Tier A. Coherent sits across multiple Layer 4 bottlenecks: **datacom transceivers** (the optical modules that connect every GPU to every switch), **indium-phosphide laser diodes** (the source for high-speed datacom), **silicon carbide power semis** (the EV / power-electronics business — separately monetisable), **industrial lasers and optical instruments** (the legacy II-VI book, cyclical but high-margin). The AI mix has grown materially over the last six quarters as the datacom transceiver revenue scaled into 800G — Coherent now derives an estimated 30-40% of revenue from AI / datacom optical, with the rest …
