Applied Optoelectronics, Inc.AAOI

Applied Optoelectronics Inc. filed its March-2026 quarterly report on 23 July 2026, and the headline is simple: revenue of $151.1 million did not cover a $25.7 million research bill, a $13.0 million operating loss, and a $14.3 million net loss, pushing diluted EPS to $-0.19 and leaving the company burning $85.4 million of operating cash. The cash and equivalents balance still sits at $439.7 million, but the cash outflow means the runway is shorter than the 400G transceivers in the catalogue.

Founded in 1999 and listed on the NASDAQ under the ticker AAOI, the company sells advanced semiconductor lasers, distributed-feedback chips, optical components (TO cans, TOSA/ROSA/BOSA), and a full range of optical transceivers from 40G to 1.6T, all marketed into telecom, data-centre, sensing, and cable/HFC networks. Its own product pages show polished images of 250 µm lasers, QuantumBandwidth amplifier racks, and 6.4T OBO line cards, but the current setback is real: the balance sheet is emitting red light even as the brochures stay bright.

Latest 10-Q (period ending 23 March 2026) shows total assets at $1.57 billion, liabilities at $459.9 million, and stockholders’ equity at $1.11 billion. Inventory rose $25.3 million to $206.2 million, while capex for the quarter was $58.2 million, a number that suggests either capacity expansion or a very expensive new hobby. Diluted shares outstanding now sit at 76.0 million, up from earlier periods, reflecting the steady issuance implied by six same-day Form 4 filings on 23 July 2026. The optics story is compelling; the cash-flow story is less so.

There is no official price chart supplied in the evidence, so any attempt to read candlesticks or levels would be invention. The company’s SEC filing index and live submissions JSON remain the primary evidence rails; readers seeking market colour will have to rely on the filings themselves rather than external price commentary. Until the cash burn slows or revenues reaccelerate, the most visible action is inside the EDGAR archive rather than on any trading screen.

What is proven: a laser company shipping product but haemorrhaging cash, with inventories climbing and capex still rising. What cannot be determined from the evidence: customer concentration, order backlog, gross margin by segment, or the precise mix of sales to hyperscalers versus legacy telcos. The company’s own product pages and image library show a broad portfolio, but they do not disclose volumes, ASPs, or utilisation rates. Until the next 10-Q or an 8-K detailing a major contract or product win, the file’s blind spots remain wide.

What would materially change the file next: a quarterly report showing positive operating cash flow, a reduction in inventory without a corresponding revenue dip, or an 8-K announcing a marquee hyperscaler design win at 800G or 1.6T. Absent such evidence, the optics remain brilliant but the financing needs a refresh.
