Why is Coherent stock surging today?

Coherent stock surged 5.1% in pre-open trading after the photonics and optical components maker delivered fiscal first-quarter 2027 results that beat analyst expectations on every key metric, with non-GAAP EPS of $2.09 topping consensus estimates near $1.98 and revenue of $2.37 billion — up roughly 50% year-over-year — clearing the approximately $2.31 billion forecast.

The headline numbers were accompanied by a landmark announcement: a five-year, approximately $20 billion long-term agreement with a major AI company for Coherent’s PhotonLink integrated optics platform, with revenue set to begin in early calendar 2028.

CEO Jim Anderson noted that "Q1 marked a strong start to fiscal 2027, with pro forma revenue up 56% year over year and non-GAAP EPS up 80%," and added that fiscal 2027 pro forma revenue growth is expected to exceed 60%.

Adding to the momentum, Stifel raised its price target on the stock to $450 from $420 today while maintaining a Buy rating, arguing that operating leverage — rather than a gross-margin surprise — was the primary engine behind the earnings beat, and that growing customer commitments are increasingly supporting capacity investments.

Earlier in the week, Northland Capital Markets had upgraded COHR to Outperform, pointing to the scarcity of indium phosphide device capabilities and the strategic read-across from Marvell Technology’s approximately $115 billion all-stock bid for rival Lumentum Holdings, a deal that has sharpened investor focus on the value of AI optics players.

The broader market backdrop on today’s session was mixed, with the S&P 500 fractionally higher and the Dow Jones gaining modestly, while the NASDAQ dipped slightly, reflecting selective caution in the technology space.

Coherent’s datacenter and communications segment — which posted 79% year-over-year revenue growth to $1.95 billion — underscored the company’s outsized exposure to AI infrastructure spending, a theme that continues to attract investor attention even as some tech names face multiple compression.

Taken together, a record quarterly revenue print, a transformative long-term AI supply agreement, upbeat forward guidance, and fresh analyst support combined to lift Coherent shares well above their prior close of $195.09, with the stock reaching $205 in pre-market trading — even as the stock remains well below its 52-week high of $440, leaving considerable room for recovery in the eyes of bulls.
