Applied Optoelectronics' case now hinges on visible production progress. Its drop on OpenAI's revenue run-rate figures reflected an accounting question, not any change in laser or memory supply, per Carrio Research. If AAOI fails again next quarter and pushes its timelines out another quarter, it will be ugly. x.comÂ
Applied Optoelectronics is the main beneficiary, from an ROI standpoint, of bipartisan legislation to bar Chinese transceivers from Eoptolink and Zhongji Innolight in sensitive US systems, which @The_AI_Investor notes. It is not yet a play on 400mW external lasers beyond 1.6T, as there is no sign it can make them with enough yield for mass production. x.com x.comÂ
Applied Optoelectronics' possible 2028 revenue makes even a 100% takeover premium too small if it delivers on 2027-28 expectations. Revenue of $6-8B in calendar 2028 at an illustrative 8x multiple would imply about $56B in market value, versus $7B today. That is the upside worth holding out for. x.comÂ
Ongoing demand makes Applied Optoelectronics' risk/reward make a ton of sense at current levels. The price makes little sense if management is credible even a shred; execution could falter, but that risk is, without a doubt, already priced in. x.comÂ
Applied Optoelectronics' Q3 and Q4 would have to be heroic to hit guidance, so a miss could still kill the stock. It trades below projected 2027 sales and much of the risk is already priced in, but that would not eliminate the downside on a miss. x.comÂ
Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com x.comÂ
Applied Optoelectronics' quarterly miss reflects capacity constraints amid insane demand, not weak demand. Capacity comes online mid-quarter, so Q1 revenue of $151M with about $190M guided next quarter implies a steep ramp toward perhaps $550-600M per quarter by 1Q27. Second-half 2026 guidance of $750-760M versus $350-370M in the first half points toward $2B next year with high margins. The market overreacted, and the reset removes an overhang for long-term holders. x.com x.com x.com x.com x.comÂ
Applied Optoelectronics keeps promising things it cannot deliver. It is now the second-priority short behind CoreWeave, reversing earlier confidence that Dr. Lin would deliver despite delays. x.comÂ
Applied Optoelectronics' projected $5.65 billion in 2027 revenue against a $6 billion market cap drives its appeal. It may be the best opportunity in the market right now. x.comÂ
Applied Optoelectronics looks undervalued if its capacity converts into the modeled revenue ramp. From disclosed capacity, quarterly revenue could rise from $858M in Q1 2027 to $1.89B in Q4 and $2.14B in Q1 2028, against a $6.8B market cap. A $7.5B annualized exit rate in 2027 at 40% gross margins would make an unchanged valuation surprising. Lumentum's capacity agreements into 2030-31 suggest demand may last beyond 2027-28, but execution risk remains. x.comÂ
Applied Optoelectronics' future earnings are not guaranteed, so its elevated price is highly susceptible to a drawdown that could create a far better buying opportunity by the end of next year. Capex can be cut, public and political pushback can delay data centers, and new data centers may fail to secure financing, any of which would cut projections. @RatWasteCapital counters that at $90 the stock trades at about 6x fiscal 2028 EPS if a $5.6B run rate holds. x.com x.comÂ
Applied Optoelectronics has interesting risk-reward around these levels given laser shortages and the scope of the 800G and 1.6T ramp it plans over the next 12-18 months. Its history still makes it a name with real risks. x.comÂ
