Coherent Soars 6% as Fabrinet’s 51% Revenue Jump Lifts Optics Stocks Ahead of Earnings
Coherent (COHR) shares rose 6% after Fabrinet reported a 51% revenue increase and raised guidance above estimates. Fabrinet's data center revenue grew 78%, aligning with Coherent's guidance. Coherent reports earnings on Nov. 4, with cash flow concerns due to negative free cash flow of $1.0 billion in fiscal 2026. Marvell's $115 billion deal for Lumentum leaves Coherent as a standalone major laser maker.

Why it matters
Fabrinet’s upside results and guidance act as a near-term sentiment catalyst for optics/data-center names, but Coherent’s cash-flow risk is highlighted as the key swing factor into its upcoming earnings.
Market read
Traders get a same-day catalyst for Coherent sentiment via Fabrinet’s upside guide, plus a sector competitive backdrop from the Marvell-Lumentum deal.
What to watch
Coherent’s main cited risk is negative free cash flow of $1.0 billion in fiscal 2026, which could dominate the earnings reaction even if revenue growth looks strong.
Background
The piece ties Fabrinet’s record quarter and upside guide to Coherent’s own data-center growth expectations, while also referencing the Marvell-Lumentum acquisition as a competitive backdrop.
Ticker impact
Coherent shares rose 6% after Fabrinet’s 51% revenue jump and guidance supported Coherent’s own data-center growth expectations ahead of its Nov. 4 report.
Likely upward bias while traders price in data-center read-through from Fabrinet, with downside risk on free-cash-flow concerns into the Nov. 4 print.
The article links Fabrinet’s data-center growth and guide to Coherent’s previously set high bar, while flagging negative free cash flow as the main risk.
Fabrinet reported record-quarter revenue up 51% and guided December-quarter revenue above consensus, driving optics/data-center read-through.

The article provides the quarter’s revenue and data-center growth plus a December-quarter guide above analysts’ expectations.
Marvell agreed to buy Lumentum in a $115 billion all-stock deal, reshaping the competitive landscape for laser/optics suppliers including Coherent.
Near-term mixed impact, with potential sector re-rating but no direct operational change for Marvell described beyond the announced transaction.
The article frames the deal as a competitive reference point for Coherent, but does not provide incremental Marvell-specific operating details.
Lumentum is the target of Marvell’s $115 billion all-stock acquisition, which the article uses to position Coherent as the remaining big laser maker not tied to a chip designer.
Likely volatility around deal terms and regulatory/timing expectations, with direction dependent on spread and deal progress.
The article states the deal size and that it is all-stock, but provides no terms, timing, or regulatory outlook.
Market effects
Reinforces positive demand expectations for data-center optics/contract manufacturing via Fabrinet’s upside guide, potentially lifting sentiment across the optics supply chain.
Primarily US-listed optics/semicap sentiment spillover; no specific regional macro catalyst cited.
Supports the broader AI/data-center capex narrative through optics supply-chain read-through, though the article is US-focused.
Counterpoint
The Fabrinet read-through may overstate Coherent’s end-demand exposure because the article itself notes some of Fabrinet’s data-center growth could come from Coherent’s rivals.
