Rosenblatt raises Coherent stock price target on transceiver growth

Rosenblatt raised Coherent’s price target to $425 from $375 and kept a Buy rating, implying further upside from the current $344.67 share price. The firm cited transceiver and optical circuit switching momentum, plus improved gross margins that could reach the high end of 39%-41% guidance in Q4 FY2026. Coherent also posted record Q3 FY2026 revenue of $1.8B and EPS of $1.41, topping expectations.

Analysis

The market is beginning to price Coherent less like a cyclical photonics supplier and more like a constrained-capacity platform business with optionality into multiple AI infra layers. That matters because the next leg of upside is no longer just unit growth; it is mix improvement and operating leverage if management can convert wafer-level process gains into sustained margin expansion. The key second-order effect is on customers’ qualification urgency: once a supplier demonstrates it can de-risk internal component content, hyperscalers and module integrators tend to consolidate volume faster, which can extend the ramp beyond what near-term consensus models assume.

The setup is also a relative-value signal against the rest of the optical chain. If Coherent is moving ahead on internal component resolution, peers with greater supplier dependence face a higher probability of schedule slippage, margin compression, or lost design wins in the next two quarters. That creates a potential divergence trade where the best-positioned name outperforms on both earnings revisions and multiple expansion while slower movers get punished by “timing risk” rather than absolute demand weakness.

The main contrarian risk is that the stock has already discounted a lot of the easy narrative. At this valuation, a single quarter of margin disappointment or a pushout in the revenue inflection could trigger a sharp de-rating because the street is anchoring on an aggressive forward EPS path. Near term, the stock can continue to squeeze higher on revisions and momentum; over a 3-6 month horizon, the more important question is whether 2027 gross margin and EPS assumptions are already close to perfection, leaving limited upside unless co-packaged optics meaningfully accelerates.

The broader implication is that AI optical winners are migrating from “promise” to “execution premium,” and that usually compresses the gap between fundamental strength and stock price only when supply catches up. Until then, the highest beta upside belongs to names with both product credibility and internal manufacturing control. If either of those breaks, the repricing can be abrupt because this tape is rewarding certainty, not just growth.

Key Decisions for Investors

• Stay long COHR tactically on dips over the next 1-3 weeks, but treat it as a momentum/trading position rather than a core hold; upside remains if revisions keep ratcheting higher, but trim into strength if it trades materially above the new target band.
• Pair trade: long COHR / short LITE for 1-3 months to express relative execution advantage in optical timing and vertical integration; this isolates winner-takes-share dynamics without taking a broad AI capex bet.
• Buy COHR upside call spreads 1-2 quarters out to monetize continued estimate revisions while capping premium risk; this is preferable to outright stock here given elevated expectations and gap risk on any guide miss.
• Set a hedge trigger for any sign of gross margin reverting toward the low end of guidance; if that happens, reduce COHR exposure quickly because the multiple is now sensitive to even small execution noise.
• Use any post-rally consolidation to add only if channel checks confirm transceiver and switching capacity remains tight; otherwise rotate into cheaper optical beneficiaries with less perfection priced in.
