Shares of Applied Optoelectronics (NASDAQ: AAOI) recouped some losses on Tuesday, climbing nearly 5% after the optical networking company unveiled its third at-the-market (ATM) equity offering of 2026, a $600 million program aimed at funding aggressive expansion in AI data center infrastructure.
The stock closed at $112.85, up 4.9% from Monday's close of $107.63, when shares tumbled 13.8% on heavy volume of 14.94 million shares. Despite the rebound, the stock remains 9.6% below its Friday closing price, reflecting ongoing investor concerns about dilution and margin pressure.
The new ATM program, announced August 21, allows the company to sell up to $600 million in shares over time, with Raymond James and Needham acting as agents. Commissions of up to 2% will be paid on sales. Based on Tuesday's price, a full exercise would equate to roughly 5.32 million shares, representing about 6.3% of the 84.91 million shares outstanding.
This marks the third ATM program initiated in 2026, following two earlier offerings that together raised $1.03 billion in net proceeds through June 30. The first program, authorized for $500 million, sold 4.83 million shares at a weighted average price of $101.72. The second, a $600 million facility, saw 2.95 million shares sold at an average of $197.26. The company's total authorized equity capacity now stands at $1.70 billion.
Management has been aggressively investing in capacity to meet surging demand for 800G and 1.6T optical transceivers used in AI data centers. Capital expenditures reached $633.7 million in the first half of 2026, with operating cash outflows of $73.8 million. The company expects to maintain high capex levels through at least 2027, expanding production in Texas and Taiwan.
Revenue in the second quarter jumped 86.4% year-over-year to a record $191.9 million, while gross profit rose 70.7% to $53.2 million. However, gross margin contracted to 27.7% from 30.3%, pressured by higher labor, material, and ramp-up costs. For the third quarter, management forecasts revenue between $255 million and $290 million, implying sequential growth of 33% to 51%, with non-GAAP gross margin expected in the 29% to 30.5% range.
Analyst sentiment remains mixed. The consensus rating is Buy with an average price target of $163.40, implying nearly 45% upside from Tuesday's close. Targets range from $109 (B. Riley) to $220 (Rosenblatt), reflecting uncertainty about production execution and margin recovery. Recent actions include Rosenblatt reiterating Buy on August 19, Needham reaffirming Buy on August 7, and Raymond James raising its target to $178 on August 11.
The new ATM represents a modest 6.3% of the company's $9.58 billion market cap, but the cumulative dilution from three offerings is a concern. Investors are weighing the potential for improved efficiency and pricing to offset share count growth against risks of delayed customer deployments, rising manufacturing costs, or lower ATM sale prices.
As of June 30, Applied Optoelectronics held $508.8 million in cash and restricted cash, a figure that will likely increase with the new program. The company's ability to convert this capital into profitable growth will be closely watched by the market.
