Pulse Analysis

Applied Optoelectronics posted $103 million in non‑GAAP revenue for Q2 2025, squarely within its $100‑$110 million guidance and representing a modest sequential rise. 5 %. 1 million, driven by higher R&D and SG&A outlays. 3 million, underscoring a capital‑intensive growth phase.

8 million, up 30 % year‑over‑year and 40 % sequentially, fueled by strong demand for 100 G and 400 G transceivers. 400 G sales accelerated 43 % YoY, benefiting from higher‑margin single‑mode products, while 100 G revenue grew 25 %. In the CATV business, revenue exploded eightfold to $56 million, reflecting new amplifier certifications with Charter and expanding orders from six additional MSOs, though it slipped 13 % sequentially after a production retool. Customer concentration remains high, with two accounts each contributing over 10 % of total revenue, highlighting both opportunity and risk.

Management projects Q3 2025 revenue between $115 million and $127 million and continues to target mid‑30 % gross margins as cost efficiencies take hold. 6 T products, with a full‑year capex plan of $120‑$150 million. The recent audit approval for 800 G production positions the company to capture the emerging hyperscale demand expected later in 2025, while domestic manufacturing mitigates tariff exposure. Investors will watch inventory levels, cash burn, and the pace of customer qualification as key levers for achieving profitability.
