What the company doesAI summary of filing

Aeluma develops photonic and electronic semiconductors based on compound materials integrated on large-diameter substrates for telecommunications, data center communications, defense, aerospace, and quantum applications. The company's products include photodetectors and photodetector arrays for near-infrared and shortwave infrared detection, lasers and optical amplifiers based on quantum dot technology, and nonlinear photonic materials. Aeluma is transitioning from a predominantly research-and-development-stage business toward commercialization, currently generating revenue from government development contracts and emerging commercial product sales of wafers, chips, and engineering samples, though commercial orders to date have been relatively small. The company operates a capital-efficient manufacturing model combining internal materials production and prototyping with external foundries and supply-chain partners. [10-K 2026-09-16]
