Coherent Corp. director Stephen Skaggs sells $629,061 in shares

Coherent shares have rebounded off a 1-week decline of 9% while the company delivered record fiscal Q4 results: revenue of $2.05B (vs. $1.99B consensus) and adjusted EPS of $1.74 (vs. $1.62 expected). Margins improved (adjusted gross margin to 40.2%, +60 bps QoQ and +210 bps YoY) and management guided ahead—Q1 FY27 guidance beat by 8% on revenue and $0.05 on EPS, alongside commentary that optical demand could exceed supply for 12–18 months. Analysts reiterated/raised targets to $420 (e.g., Stifel and Needham), supporting a positive near-term setup despite an insider Rule 10b5-1 sale of 2,272 shares totaling $629k.

Analysis

COHR looks like the cleaner expression of the AI-infrastructure bottleneck than NVDA: if optics remain supply-constrained, pricing power migrates upstream to the component layer while the hyperscaler/GPU stack absorbs only the headline demand upside. The important second-order effect is not just revenue growth, but mix-driven margin expansion if capacity stays tight; that is why the market may keep re-rating COHR faster than the broader semi group even after a large run.

The main risk is that this is a duration trade masquerading as a cyclical trade. Once management signals capex is being pulled forward, the market usually starts discounting a 6-18 month normalization in lead times, which can cap multiples before volumes peak. The insider sale is not a useful signal given the 10b5-1 structure; the real watch item is whether upward estimate revisions continue while the stock holds above recent support. If the shares cannot reclaim the prior high area over the next few weeks, the move is vulnerable to de-rating despite strong fundamentals.

Consensus may be underestimating how much of the value accrues to the bottleneck supplier versus the end-demand beneficiaries. NVDA and DELL can still post strong top-line prints while absorbing schedule risk, inventory swings, and customer concentration, so the cleaner relative-value trade is long COHR versus the broader hardware/systems complex. What would falsify the thesis: any sign that optical supply is catching up faster than expected, gross margin stalls below ~40%, or guidance stops stepping up over the next 1-2 quarters.

Key Decisions for Investors

• Long COHR on pullbacks over the next 1-2 weeks; use recent weakness as entry if the stock holds the prior breakout zone. Risk/reward is favorable while supply remains tight, but trim if management commentary suggests lead times are shortening faster than expected.
• Pair trade: long COHR / short DELL for 1-3 months. Thesis: COHR captures the scarcity premium, while DELL is more exposed to timing risk and margin pass-through in AI server demand; this isolates the component bottleneck from the systems assembler.
• Relative value: long COHR vs short NVDA in a small size basket. NVDA remains the demand leader, but COHR may have more upside from incremental supply scarcity; use this only if you want to fade some of the crowded AI-leader multiple compression risk.
• Set an alert if COHR loses the post-earnings support level or if 1Q27 guide is no longer beating expectations. That would be the first sign the market is pricing in normalization rather than scarcity.
• Avoid chasing here with outright calls unless implied vol collapses; the stock has already repriced substantially, so the better asymmetry is via equity/pair exposure rather than levered optionality.
