NEW YORK, May 20, 2026, 09:17 (EDT)
- AAOI was quoted at $177.40 in premarket trading at 9:13 a.m. EDT, up 3.54%, after closing Tuesday at $171.33.
- Six May 19 Form 144 notices by senior officers covered proposed sales totaling about 201,489 shares, or about $34.8 million by disclosed market values.
- The company’s May 14 filing lets it sell up to $600 million of common stock from time to time through Raymond James and Needham.
Applied Optoelectronics shares rose before the Nasdaq open on Wednesday, testing a rebound after a two-day fall that put fresh attention on executive sale notices and a new $600 million share-sale program.
The Sugar Land, Texas-based optical-networking company closed at $171.33 on Tuesday, down 1.1%, after an 8.98% drop on Monday. Its premarket quote was $177.40 at 9:13 a.m. EDT, before regular Nasdaq trading, which starts at 9:30 a.m. ET.
The move matters because AAOI has become a volatile way to trade demand for fast data-center links used in artificial-intelligence computing. The company says its transceivers plug into switches and servers and send data over fiber; 800G means an 800-gigabit-per-second optical link, a speed level now central to its growth pitch.
Company filings on Tuesday showed Form 144 notices by Chief Executive Chih-Hsiang “Thompson” Lin, Chief Financial Officer Stefan Murry, Asia general manager Shu-Hua “Joshua” Yeh, North America general manager Hung-Lun “Fred” Chang, Chief Legal Officer David Kuo and officer Min-Chu “Mike” Chen. Form 144 is a notice of a proposed sale; the SEC’s investor site says filers must have a bona fide intention to sell within a reasonable time, but the notice is not the same as a completed open-market sale. Applied Optoelectronics, Inc.
The largest notice was Lin’s proposed sale of 58,000 shares, with an aggregate market value of about $10.0 million. Murry’s notice covered 33,000 shares valued at about $5.7 million, while Yeh’s covered 39,154 shares valued at about $6.8 million.
Investors were already weighing possible dilution. On May 14, Applied Optoelectronics entered an equity distribution agreement allowing it to sell up to $600 million in common stock through Raymond James and Needham in “at-the-market” offerings, meaning shares can be sold into the market over time at prevailing prices rather than in one fixed block. The company said it has no obligation to sell shares and may suspend sales at any time.
The financing follows a sharp run-up and equally sharp swings. A prospectus supplement said AAOI’s stock had ranged from an intraday low of $15.06 to an intraday high of $233.67 over the 12 months before the filing. The stock touched that $233.67 high on May 13, then fell in the next three sessions.
Applied Optoelectronics’ operating case is still tied to the 800G ramp. The company reported first-quarter revenue of $151.1 million, up from $99.9 million a year earlier, with data-center revenue rising to $81.4 million from $32.0 million.
Lin said first-quarter results were “in line with our expectations” and cited strong customer engagement around 800G and 1.6 Tb products. Murry said the company delivered its “fourth consecutive quarter of record revenue” and exited the quarter with capacity near 100,000 800G transceivers per month. GlobeNewswire
For the second quarter, the company guided for revenue of $180 million to $198 million and non-GAAP earnings ranging from a loss of 3 cents a share to profit of 3 cents a share. Non-GAAP figures strip out items a company views as not part of normal operations; investors use them to compare operating performance, but they are not calculated under standard accounting rules.
The peer read was mixed. Larger optical names Coherent and Lumentum have traded with the same AI data-center theme, but Barron’s reported that both fell Monday after a prominent AI investor exited positions, while Reuters said U.S. chip stocks were firmer Wednesday ahead of Nvidia results, a wider test of AI infrastructure demand.
The risk is that more share supply meets a tape that has already turned jumpy. Applied Optoelectronics warned in its prospectus that at-the-market sales could dilute buyers and that future stock sales or financings could pressure the share price; a slower 800G qualification or capacity ramp would also make the second-half growth story harder to defend.
