Coherent Corp. (NYSE: COHR) continued its remarkable rally on Friday, with shares climbing 10.7% to $369.99 by 10:52 a.m. EDT. The stock has now gained an extraordinary 40.7% since the close on July 31, propelled by a U.S. government proposal that could reshape the optical networking industry.
The catalyst emerged from Washington, where the Federal Communications Commission (FCC) is reportedly preparing to ban imports of new Chinese optical transceiver models. According to Reuters, the draft measure is still subject to change or withdrawal, but investors have already priced in a significant shift in market dynamics. Western suppliers, particularly Coherent, are seen as primary beneficiaries if the restrictions take effect.
Coherent's surge has added roughly $21 billion to its market capitalization since July 31, based on Friday's intraday price and unchanged share count. The equity now trades at $72.4 billion, having reached a session high of $386.50 earlier in the day. This rapid repricing has nearly exhausted the average analyst price target of $383.41, which implies just 3.6% upside from current levels.
Jefferies analyst Blayne Curtis described the report as "directionally bullish" for Coherent, noting that Chinese suppliers hold at least a 60% share of the global optical transceiver market. If the ban materializes, Western manufacturers could capture a substantial portion of that demand, though capacity constraints remain a key question.
The rally has also lifted the broader sector. Applied Optoelectronics (NASDAQ: AAOI) surged 9.1% to $135.51, while Lumentum Holdings (NASDAQ: LITE) gained 4.1% to $872.54, and Fabrinet (NYSE: FN) rose 2.9% to $559.87. The broad-based gains suggest investors are betting on a sector-wide tailwind rather than company-specific factors.
Coherent is scheduled to report its fiscal fourth-quarter results on Wednesday, August 12, after the market close. Management's guidance calls for revenue between $1.91 billion and $2.05 billion, with a midpoint of $1.98 billion—a 9.7% sequential increase. Non-GAAP EPS is projected at $1.52 to $1.72, while gross margin is expected to expand to 40% at the midpoint, up 40 basis points from the prior quarter.
CEO Jim Anderson emphasized in May that the company was "rapidly expanding capacity to meet demand," a statement that now carries even more weight given the potential policy shift. However, at $369.99, the stock trades at 57.1 times the annualized Q4 midpoint EPS, a rich valuation that leaves little room for disappointment.
Analyst ratings remain mixed. Raymond James' Simon Leopold has a Strong Buy with a $435 target (17.6% upside), while Rosenblatt's Mike Genovese rates it Buy with a $425 target. Bank of America is Neutral with a $400 target, and Morgan Stanley's Meta Marshall has an Equal Weight with a $330 target, implying 10.8% downside. The wide dispersion reflects uncertainty about the FCC's next steps and Coherent's ability to capitalize on any market share gains.
Investors will be watching next week's earnings for signs of margin strength, capacity updates, and fiscal 2027 guidance. A modest beat may not be enough to sustain the rally, given the substantial re-rating already underway. Risks include the FCC proposal being revised or dropped, insufficient Western capacity to replace Chinese suppliers, and Beijing's control over critical indium-phosphide inputs.
