Coherent Lags Peers on Short Positioning as Analysts Trim Targets

Among the closest peers to Coherent Corp., short positioning is comparatively light. FN and KN carry higher correlation to COHR's price moves, yet neither has seen the same scale of short-interest unwinding that COHR experienced through late October. Coherent's SI % of free float now sits at 5.7%, down sharply from above 7% of float implied by the mid-October share count of roughly 11 million. That is a meaningful unwind, but not an extreme starting point relative to the peer group. Availability is extremely loose at 3,025%, meaning there are roughly 30 shares available to borrow for every one currently lent out. The cost to borrow is 0.37%, well below the October range that briefly pushed toward 0.54%. The borrow market is not under stress.

Peers moved modestly ahead of Friday's results. The median one-week gain across COHR's eight closest correlated names came in around 1.2%. COHR itself gained 0.5% on the week before the 11.3% drop on earnings day erased the bounce and then some, taking the stock to $210.32. That left it down 28% over the past month. FN fell 6.1% on the day. GLW dropped 4.3%. KEYS lost nearly 7%. The selloff on Friday was not confined to COHR, but COHR's move was the sharpest in the group.

The analyst picture turned more cautious in the days around the print. Morgan Stanley lowered its target to $325 from $375 on October 30, maintaining its Equal-Weight rating. Several others trimmed targets in the weeks prior: TD Cowen cut to $275 from $395, Susquehanna to $350 from $425, and B. Riley to $262. Against those moves, StoneX initiated with a Buy at $425 and Needham, also Buy-rated, cut its target to $380 from $420. The consensus mean target is $392, roughly 86% above the current price, but the direction of travel is clearly downward. The debate centres on whether COHR's InP capacity expansion can be executed fast enough to convert AI infrastructure demand into free cash flow. The bear case points to $1.023B of negative free cash flow in FY26, inventory up 79.5% to $2.58B, and $11.8B of vendor commitments. The bull case points to $1.615B in Data Centre and Communications revenue last quarter, CPO and NPO engagements in double digits, and management's target of more than doubling InP capacity by end of CY27.

On the activist register, BCPE Watson filed a Schedule 13D on COHR in late 2025 and has amended five times since, most recently in February 2026. The filing type signals activist intent rather than passive ownership. The previous disclosed stake was 5.2%, though positions are as-last-disclosed and a holder can drop below the 5% threshold without a further filing. Wikipedia attention for COHR hit a z-score of 3.5 through the end of October, well above the company's own 90-day baseline, consistent with the wave of analyst activity and the sharp price moves drawing broader retail attention.

The November 4 print will test whether the InP capacity ramp is tracking management's timeline and whether the working-capital build is stabilising, given that those two questions are the primary distance between where the consensus target sits and where the stock is trading.
