Opening Summary
Coherent Corp. (COHR), a global photonics leader that develops lasers, optical transceivers, and engineered materials for data-center, communications, and industrial markets, surged about 9.41% in Thursday's session. Shares traded near $185.73, up from the prior close of $169.76, marking a decisive upward move after a sharp decline the day before. The rebound reflected a combination of an oversold technical bounce, bargain-hunting following a sector-wide AI selloff, and renewed focus on the company's robust quarterly results and aggressive long-term guidance.
Oversold Rebound After Election-Driven AI Selloff
The biggest driver behind today's price rally was a snapback from the previous session's steep losses. On Wednesday, COHR shares fell roughly 13% even though the company delivered a strong earnings report, as midterm election results triggered a broad retreat in AI and semiconductor names. The Nasdaq fell sharply intraday and chip-sector gauges were down more than 10%, dragging optical names lower across the board. With sentiment oversold, buyers stepped back in Thursday to re-accumulate shares at discounted levels, fueling a sharp intraday rebound.
Strong Q1 Results and Raised Guidance
The rebound was supported by fundamentals rather than sentiment alone. For the fiscal first quarter ended September 30, 2026, Coherent reported revenue of $2.37 billion, up about 50% year over year, while non-GAAP earnings per share of $2.09 beat consensus estimates of roughly $1.97. Management guided second-quarter revenue to $2.55 billion–$2.75 billion and non-GAAP EPS to $2.28–$2.48, both above analyst expectations. The company also said it expects fiscal 2027 pro forma revenue growth to exceed 60%, with its first $3 billion revenue quarter expected before the end of the fiscal year.
$20 Billion PhotonLink Agreement Boosts AI Demand Narrative
Adding to the bullish tone, Coherent disclosed a roughly $20 billion, five-year long-term agreement for its PhotonLink optical interconnect platform with a major AI customer. The company expects PhotonLink revenue to exceed $100 million in the March quarter and to reach more than $250 million per quarter before the end of calendar 2027. Data center and communications revenue grew about 79% year over year, underscoring continued strength as AI data centers transition from copper to optical connectivity.
Market Context and Trading Activity
Thursday's move aligned with a broader recovery in optical-communications stocks, which rebounded as a group after Wednesday's selloff. The rally in COHR outpaced the broader market, reflecting its elevated beta and the heavy prior-day losses that left it deeply oversold. Trading volume in the prior session was well above the stock's typical average, indicating that institutional repositioning and forced selling likely contributed to the earlier decline and set the stage for the bounce. Technically, shares remained below their recent moving averages, meaning the recovery is still in its early stages rather than a confirmed trend reversal.
What Comes Next for COHR
Investors will be watching whether COHR can sustain momentum above key technical levels and whether the broader AI-funding narrative stabilizes. The company's next quarterly report is expected in early February, and management has flagged continued heavy capital expenditures and elevated inventory as factors to monitor, with operating cash flow turning negative last quarter. While demand visibility now extends into 2028 and analysts have highlighted the strength of guidance, risks remain around AI-spending sentiment, margin execution, and potential supply-chain constraints. The balance between robust top-line growth and near-term cash-flow pressure will be central to how the stock trades in the coming weeks.
