AXT (AXTI): Options Priced a 15.3% Move, Stock Delivered 42.45%

AXT reported second-quarter 2026 results on 30 July 2026. Options ahead of the report were priced for a 15.3% move -- already a large number for a stock this size. What actually happened was 42.45%, 2.77 times that.

What AXT reported

Revenue reached $47.6 million, far above the $34.8 million analysts had modeled, and adjusted earnings per share came in at $0.19 against a $0.07 estimate. Indium phosphide wafers -- substrates used in the optical links that move data inside AI data centers -- drove the beat: that product line alone hit a record $30.7 million, nearly 65% of total revenue for the quarter.

The deal behind the demand

Two days before the report, on 29 July 2026, AXT disclosed a six-year capacity-reservation agreement with Lumentum covering indium phosphide substrate supply, backed by $87.0 million in deposits credited against future shipments rather than booked as revenue today. A multi-year reservation of that size is a company locking in demand rather than hoping for it, which is part of why the market's reaction went well beyond the priced range.

What this measures, and what it does not

A 2.77× outcome once does not mean AXT's options are mispriced as a rule -- it means this specific report landed further outside the priced range than the market expected. Whether the options market adjusts its pricing ahead of AXT's next report is a separate question this number does not answer.
