Mizuho on opticals: We see CW laser capacity ramping sharply from ~83M units in 2025 to ~427M by 2029E (Ex-7), driven by SiPho pluggables at 1.6T/3.2T and the initial NPO/CPO transition into 2027-2029E as we see yields improving. We see $COHR profitability lagging as we believe it relies on external lasers for it's leading-edge products (also sourced from LITE) and its business model remains more transceiver-heavy which is lower-margin vs LITE, which we see as more laser-oriented. On margins, LITE continues to ramp GMs sharply from low-30% in early 2024 to the low-50% range in 2026-2028E, while COHR rises more gradually to only the low-40s%, resulting in a 10-11ppt gap. We believe ELS pluggable modules housing a laser source could start to ramp as well. ELS as the back plate pluggable component retains serviceability in case of a component failure, while enabling laser light to transmit the converted optical signal and advance more efficient optical architectures. $LITE has noted orders for ELS have begun, with we believe potentially 2x content opportunity compared to laser chips alone. Ex-China, we believe COHR is the largest transceiver assembler with ~17% market share, differentiated via deep InP vertical integration and high in-house component supply. We note some tailwinds with $NVDA, incl. $2B investment and multi-year CPO/CW supply agreement through YE-2030E. We estimate LITE's Cloudlight business (acquired Nov 2023) is ramping strongly toward ~$900M C26E revenues and ~$1.2B by C27E, but remains smaller at >6% market share. Similar to COHR, LITE is leveraging CW/EML in house manufacturing, but we believe it is entirely reliant on in-house laser chip supply, with a path to mid-30% GM. FN is an important assembler, serving NVDA's designed transceivers alongside merchant OEM contracts. $AAOI (NC) is another key domestic assembler, operating three Taiwan facilities (~795K sq ft) with a new Pearland, Texas facility (800G/1.6T) and an estimated SOP in early 2027E.
