Record Revenue, Falling Shares After the November 4 Report

Coherent (NYSE:COHR) was trading down 8.61% at USD 212.10 on Friday, November 13, 2026, in market data that is the figure of record for the live session only. No company announcement dated November 12 or 13 explaining the move was found. The company reported fiscal first-quarter results on November 4, 2026: revenue of USD 2.37 billion, GAAP earnings of USD 1.90 a share and non-GAAP earnings of USD 2.09. Datacenter and communications revenue reached USD 1.95 billion, while industrial revenue was USD 418.6 million. A published analysis said the shares had already lost about 40% from their post-August peak before the print.

Heavy Capex, Inventory Build and Negative Operating Cash Flow

Coherent supplies lasers, optical components and transceivers for AI data centers and industrial uses. Capital spending jumped to USD 776 million, and a published analysis said inventories rose about USD 760 million to USD 3.34 billion. Operating cash flow was negative USD 92.7 million. Cash and equivalents were USD 1,552.9 million, with USD 200.0 million of short-term investments and about USD 3.98 billion of long-term debt. GAAP earnings also benefited from a USD 22.8 million tax gain, according to the same analysis, and the effective tax rate guide for next quarter is 18% to 20%.

Raised Targets Versus Execution and Timing Risks

Management guided second-quarter revenue to USD 2.55 billion to USD 2.75 billion and non-GAAP gross Margin to 40% to 42%. It raised its long-term gross margin target to above 45% by the end of calendar 2028, from above 42%, and said fiscal 2027 pro forma growth should exceed 60%, with a first USD 3 billion revenue quarter targeted by fiscal year-end. A roughly USD 20 billion agreement, per the analysis, generates no revenue until early calendar 2028. Analysts also flagged possible indium phosphide oversupply and data-center financing limits. Optical stocks sold off together on November 5, when a published report put the S&P 500 down 4.36%, but no driver specific to Friday was verified. In market data Fabrinet and Applied Optoelectronics were also down more than 8% in the same session, which fits a group move without proving a shared cause.

Where Things Stand

No single cause was found. Coherent (NYSE:COHR) is down 8.61% nine days after a quarter that beat published estimates and raised guidance, and no company news from November 12 or 13 was located. The pattern matches earlier optical selloffs tied to AI-spending worries, but that link is not verified for today. Cash burn from capital spending, rising inventory and about USD 4.0 billion of debt give sellers specific points to focus on. Next markers are second-quarter results, capex trends and any change in data-center build plans.
