IntelliEPI says Japan substrate outage hit 2Q26 revenue

IntelliEPI said on August 27 that revenue in the second quarter of 2026 was pressured after a Japanese substrate supplier shut down for nearly three weeks during the Golden Week holiday, reducing InP substrate availability and limiting indium phosphide production. The compound semiconductor epitaxy maker said demand for InP products tied to high-speed optical communications in AI data centers remained strong, and that substrate supply, not market demand, was the main short-term constraint.
