Semiconductor GM% as Valuation Multiple Anchor

For AI semiconductor infrastructure companies, gross margin percentage is the primary signal the market uses to determine which valuation framework applies. Above ~80% GM, the market prices the company as a software-like infrastructure play (30x+ revenue). Below ~65-70% GM, it reprices as a systems/hardware company (15-20x revenue). The 70-75% range is "no-man's-land": the market is uncertain which framework applies, so it assigns elevated repricing risk even when revenue beats are strong.

Evidence

• ALAB Q4 FY25: GM at 75.6% declining toward 70-72% guidance; stock -10% AH despite 8% revenue beat and 92% YoY growth. Market reaction consistent with "no-man's-land" uncertainty premium being removed.
• ALAB analysis explicitly frames the question: "Is this a software-like infrastructure play (80%+ GM, deserves 30x+) or a systems company (65-70% GM, deserves 15-20x)?" — at 74% declining, the framework ambiguity itself is the risk.

Implication

When evaluating AI semiconductor companies, note the GM trajectory relative to these thresholds before assigning a valuation multiple. A company in the 70-75% range with declining GM should be modeled with multiple compression risk even if top-line growth remains strong. Conversely, a company holding or expanding GM above 78-80% on a mix shift to higher-value products warrants a valuation re-rate. The entry trigger in a compression phase: two consecutive quarters of GM stabilization at or above a defensible floor before adding to position.
