GoPro Zooms 34% Higher on Starman Optical Merger and Markiplier Stake; Coherent Climbs 7%, Lumentum Gains 3%
GoPro jumped 34% after announcing a Starman Optical merger and a stake involving Markiplier, while Coherent rose 7% and Lumentum gained 3% in the same optical-market reaction. The move puts COHR’s $7.1B revenue base and 22.5% year-over-year growth in focus.
The market reaction centered on GoPro, which rose 34% after the company announced a merger with Starman Optical and a stake involving Markiplier. Coherent climbed 7% and Lumentum gained 3%, indicating that traders extended the move beyond the named transaction into publicly traded optical and photonics companies. Deal terms, the size of the stake, a transaction value, and a stated revenue impact for any of the companies involved remain undisclosed.
Coherent enters the story with a substantial existing operating base rather than as a newly disclosed beneficiary of the deal. Its latest enrichment shows revenue of $7.1B for the fiscal year ended 2026-06-30, up 22.5% year over year, with diluted EPS of $4.12 and net margin of 11.3%. Those figures establish recent scale and growth, though it is unclear whether GoPro's transaction will add orders, customers, or earnings to Coherent.
For COHR, the connection is market exposure rather than an announced contract. Coherent's optical business is being grouped with Starman Optical alongside Lumentum, while GoPro and Starman Optical are the companies directly named in the merger. Markiplier's involvement may explain attention around the GoPro transaction, but no mechanism links the stake to Coherent's revenue, costs, contracts, or regulatory position.
The main uncertainty is the absence of transaction detail. It is not clear what Starman Optical contributes, whether the merger is primarily strategic, financial, or promotional, or why the announcement should alter estimates for Coherent or Lumentum. The 7% move in Coherent and 3% gain in Lumentum are market reactions, not evidence of a new order or change to guidance.
The next useful evidence would be a filing or company release describing the merger terms, Starman Optical's operations, and any commercial relationship with the listed optical names. For Coherent, the relevant numbers are revenue of $7.1B, 22.5% year-over-year growth, diluted EPS of $4.12, and net margin of 11.3% rather than an unquantified spillover from GoPro's announcement.
The GoPro merger headline lifted GPRO, COHR and LITE, but without deal terms or a disclosed commercial link the evidence does not yet move the fundamental risk for COHR beyond its existing $7.1B, 22.5%-growth profile.
The immediate move is difficult to underwrite because the supplied report gives no transaction value, operating contribution, or contract connecting Starman Optical to Coherent. COHR’s $7.1B revenue base and 22.5% year-over-year growth provide a concrete fundamental backdrop, but they do not establish that this announcement changes earnings expectations.
The read is invalidated if a company filing or release shows that the merger creates a material commercial relationship or earnings contribution for Coherent.

Price context does not establish that the story caused the move.
Coherent’s 22.5% year-over-year revenue growth and the 7% market reaction could support continued optical-sector interest if later disclosures show a meaningful industry connection.
The direct deal is GoPro’s, and the absence of transaction terms or a disclosed Coherent contract leaves the 7% COHR move vulnerable to fading as an unexplained sympathy reaction.
