[Comparison of U.S. Stock Optical Interconnect Leaders COHR and LITE: Revenue Gap Rapidly Narrowing, LITE Shows Superior Profit Elasticity and Density] BlockBeats News, August 14, analyst qinbafrank published an article comparing the two leading companies in the U.S. stock optical interconnect sector, Coherent (COHR) and Lumentum (LITE). The differences in their positioning determine distinct investment logics: Coherent is the scale and platform leader in the U.S. photonics industry, with advantages in scale, product breadth, manufacturing platform, long-term technology stack, and customer coverage. Lumentum, on the other hand, stands out as the leader in profit density and profit elasticity within the AI optical value pool, significantly ahead in growth rate, gross margin, operating leverage, current operational quality, and net liquidity. The size gap between the two leaders is rapidly narrowing—Coherent's full-year revenue for fiscal year 2026 is 2.36 times that of Lumentum, but by the fourth quarter of fiscal year 2026, it has decreased to 2.03 times, and the midpoint guidance for the first quarter of fiscal year 2027 further narrows it to 1.84 times. Based on the midpoint guidance for the next quarter, Coherent's revenue is approximately 1.84 times that of Lumentum, but its implied Non-GAAP operating profit is only about 1.04 times. With approximately 2.03 times the quarterly revenue, Coherent generated only about 1.62 times Lumentum's Non-GAAP gross profit, 1.21 times operating profit, and 1.08 times net profit. This comparison clearly demonstrates that Lumentum significantly outperforms Coherent in profit quality and operating leverage, while the gap in revenue and profit scale between the two is rapidly shrinking.
