GoPro Zooms 34% Higher on Starman Optical Merger and Markiplier Stake; Coherent Climbs 7%, Lumentum Gains 3%

The market reaction centered on GoPro, which rose 34% after the company announced a merger with Starman Optical and a stake involving Markiplier, according to Yahoo Finance. Coherent climbed 7% and Lumentum gained 3%, indicating that traders extended the move beyond the named transaction into publicly traded optical and photonics companies. The report does not provide deal terms, the size of the stake, a transaction value, or a stated revenue impact for any of the companies involved.

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, but the headline does not say that GoPro’s transaction will add orders, customers, or earnings to Coherent.

For COHR, the concrete connection is therefore market exposure rather than an announced contract. Coherent’s optical business is being grouped with the news 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 linking the stake to Coherent’s revenue, costs, contracts, or regulatory position is provided.

The main uncertainty is the absence of transaction detail. It is not clear from the report 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 in the supplied material 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 next dated event that could settle the read is not supplied in the source material, so the story does not support a forward directional call. Until those details appear, the relevant numbers are Coherent’s $7.1B revenue, 22.5% year-over-year growth, $4.12 diluted EPS, and 11.3% net margin rather than an unquantified spillover from GoPro’s announcement.
