AAOI: $635M capex in H1 2026 for manufacturing expansion; expects elevated 2026 capex to support 800G/1.6T transceiver production

“Net cash used in investing activities was $633.7 million during the six months ended June 30, 2026 compared with $75.2 million in the six months ended June 30, 2025, an increase of 742.8%, primarily driven by capital expenditures of $335.1 million, which included $169.0 million capital expenditures in the US, $62.8 million in Taiwan, and $103.3 million in China. The increase in capital expenditures was primarily attributable to facility expansion and equipment purchases to support increased production capacity for the Company's internet data center and broadband product lines, including investments related to Quantum Bandwidth products and the continued expansion of manufacturing operations for 400G, 800G, and 1.6T transceiver products. Management expects that 2026 CapEx will continue to be elevated above past year levels, driven by the need to expand production capacity to meet customer demand.”
