Cohu Shares Slip Ahead of Q3 Earnings Amid Rising Short Interest and Insider Sales

Shares of Cohu (NASDAQ: COHU) fell 7.45% on Oct 16, closing at $50.81, after a steep intraday swing that saw the price dip to a low of $50.27. The decline follows a surge in short interest, heightened insider selling, and growing uncertainty ahead of the company’s Q3 2026 earnings release on Oct 28. Analysts remain broadly bullish, but the market appears to be reassessing the sustainability of recent growth and the impact of macro‑economic headwinds.

Recent Results and Updated Guidance

Cohu reported Q2 2026 revenue of $149 million, a 38.4% year‑over‑year increase driven by AI‑related high‑performance computing (HPC) demand. Gross margin improved to 45.4%, above the prior‑year 43.7% level. The company posted a net loss of $0.2 million versus a $16.9 million loss a year earlier, and adjusted EBITDA of $18.4 million (12.3% of sales). Management raised FY 2026 revenue growth guidance to roughly 35% and forecast Q3 2026 sales of $170 million ± $7 million, reflecting a projected 14% sequential increase.

Market Sentiment: Short Interest and Insider Activity

Short interest rose to 9.0 million shares, representing roughly 19.5% of the float, up 4% from the prior period and 181% since Oct 2025. The days‑to‑cover metric increased to 9.1 days, a 5.2% rise, signaling heightened bearish positioning. Insider sales added to the negative sentiment: CEO Luis A. Muller sold 21,662 shares at $73 each on Oct 2, and other executives filed planned sales of several thousand shares in mid‑October, totaling about $8.27 million in proceeds. Such activity often prompts investors to adopt a more cautious stance ahead of earnings.

Liquidity, Debt Profile, and Capacity Expansion

Cash and short‑term investments stood at $215.7 million as of June 27, while total debt, dominated by the 1.5% convertible senior notes due 2031, was $287.5 million. The notes carry a modest coupon and a fair‑value balance of $713.8 million, reflecting a sizable market premium. The company is expanding its Malaysia manufacturing footprint, targeting a 50% output increase by year‑end and a potential doubling by mid‑2027, intended to support the growing HPC pipeline.

Macro and Industry Landscape

The broader semiconductor equipment sector remains volatile. US manufacturing PMI rose to 57.0 in September, indicating expanding industrial activity, yet the PHLX SOX index is down roughly 14% from early‑October levels. Federal Reserve expectations of further rate hikes in September, October and December add financing cost pressure to AI‑related capex, the primary end‑market for Cohu’s test handlers. A temporary US‑China tariff truce through Jan 2027 provides a modest tailwind, but elevated rates and a strong dollar continue to foster risk‑off sentiment across cyclical semiconductor stocks.

Strategic Outlook and Competitive Position

Cohu’s pipeline includes four qualified HPC customers representing roughly $190 million of annual spend, with an additional $200 million in near‑term qualification. The company expects a fifth qualification by mid‑Q1 2027. Its Eclipse platform, featuring T‑Core Active Thermal Control, competes directly with Taiwan’s Han Precision, a rivalry that is intensifying as power‑dissipation management becomes critical for next‑gen processors. Recurring revenue from application kits, thermal‑head upgrades and a subscription‑software business now accounts for roughly 53% of Q2 sales, providing a modest hedge against cyclical equipment demand.
