COHR — Coherent, Inc.

The Q4 FY26 beat — record $2.05B revenue, ~34% YoY growth, and non-GAAP EPS of $1.74 versus $1.58 consensus — plus ~60% YoY datacenter/communications growth have kept analyst sentiment bullish, with recent targets from Jefferies ($420), Morgan Stanley ($375), and BNP ($420). However, the share price has been volatile in August as high-multiple AI names de-rated, so sentiment is bullish on fundamentals but more cautious on near-term momentum.

Every quarter in the dataset grew sequentially: revenue went from $1.05B in Sep-2023 to $2.05B in Jun-2026. The latest quarter's +33.8% YoY and +13.3% QoQ compare with +2.4% QoQ a year earlier, so growth is accelerating, not just recovering. Gross margin expanded from roughly 29% to 38.5%, and operating margin went from slightly negative to 12.4% over three years; GAAP net income swung from -$67.5M to +$240.5M. The clear offset is cash conversion: free cash flow was -$493M in the June quarter on $563M capex, a deliberate expansion of InP/transceiver capacity rather than a sign of collapsing operations.

As of 2026-08-27, COHR is expensive on trailing numbers: P/E TTM of 67.9, P/S TTM of 8.1, and P/B of 5.3 versus a 5-year average P/S of 3.5. On forward consensus EPS of $9.44 for FY27, the forward P/E is about 31x, which is more reasonable for a company compounding at 30%+ but still not cheap. The balance sheet is okay (D/E 0.33, current ratio 2.4), but the 5.7% 'dividend yield' in the dataset looks like a data error and should be ignored.

The stock has fallen from $440 to $295 while FY27 EPS estimates have moved higher, so the implied forward multiple has compressed from roughly 47x to 31x. At $295, the price is no longer pricing in perfection, but it still assumes the AI optical up-cycle continues and margins keep expanding. If Coherent reaches a $3B quarterly run-rate by late FY27, this entry will look reasonable; if hyperscaler spending pauses or 1.6T/CPO execution slips, the stock has no free-cash-flow cushion and multiple contraction could continue.

As of 2026-08-27, RSI was 47.06 — neutral, not oversold. Price was 5.6% below the 20-day and 8.2% below the 50-day, yet 8.3% above the 200-day (~$273). That is an intermediate-term pullback inside a long-term uptrend. For an entry, waiting for a reclaim of the 50-day is the safer momentum trigger; the 200-day is the key support to watch for longer-term accumulation.

• Hyperscaler AI infrastructure capex is the dominant demand driver; high-speed optical transceivers and CPO are mission-critical to GPU cluster scaling.
• High bond yields and interest rates create multiple-compression risk for high-beta (2.1) AI hardware names like COHR.
• Proposed CHIPS Act award of ~$50M supports U.S. onshoring of critical photonics and semiconductor supply chains.
• Indium phosphide wafer capacity is a bottleneck; scaling 6-inch InP and 300mm SiC is key to meeting AI data center demand.
• Geopolitics and export controls could disrupt global semiconductor supply chains and customer demand patterns.

• ECOC 2026 on September 21: planned unveiling of the PhotonLink integrated optics/CPO platform.
• Q1 FY2027 earnings and guidance: watch for continued sequential acceleration and the path to a $3B quarterly revenue run-rate.
• 1.6T transceiver ramp and 6-inch InP capacity milestones, plus potential new long-term agreements extending into 2028.

• Customer concentration and hyperscaler capex cyclicality: any AI spending digestion period would hit orders hard.
• Execution and technology risk on 1.6T transceivers, CPO, and InP capacity expansion.
• Valuation/multiple risk: at ~31x forward EPS with negative free cash flow, there is limited cushion if growth decelerates.
• Competition from optical module and photonics peers could pressure share and pricing.

As of 2026-08-27, COHR is a genuinely strong AI-infrastructure compounder with accelerating revenue, expanding margins, and order visibility into 2028, but the stock is not cheap at ~31x forward EPS with negative FCF. I lean Neutral rather than bullish because the market already knows most of the good news and the high beta cuts both ways; this is a 'great company, fair-to-rich price' situation, not an urgent buy or sell.

Applied a 36x forward P/E to FY27 consensus EPS of $9.437. The 36x multiple is supported by roughly 30-40% multiyear growth potential and a leading position in AI optical/1.6T transceivers, but it is capped by high beta (2.1), negative FCF during the capacity build, and rich P/S versus history. This yields $339.73, between the current price and the $389 consensus price target.
