AAOI APPLIED OPTOELECTRONICS, INC. Insider Trading

Director Cynthia Delaney sold 56,575 shares of AAOI for $10.7M at $189.23; holds 59,647 shares post-sale.

Delaney reduced her AAOI stake by 56,575 shares (-48.7% vs pre-transaction holdings), selling at $189.23 when the stock currently trades at $169.02, marking a -27.7% decline from the 52-week high of $233.67. Her single prior AAOI sale on 2026-03-04 produced a 90-day return of +83.5%, indicating the stock rose after that sale rather than fell, making it poorly timed for a seller. The company posted $151.1M in quarterly revenue with an annual growth rate of +82.8%, but remains unprofitable with net income of -$14.3M over its most recent full fiscal year, presenting a mixed fundamental picture typical of high-growth, unprofitable technology firms.

Yeh Shu-Hua sold 39,154 shares of AAOI at $173.26 for $6.8M, reducing stake by 7.8%; stock now -26.7% from 52-week high.

Yeh Shu-Hua sold 39,154 shares at $173.26 on 2026-05-19, bringing holdings from 501,584 to 462,430 shares. The stock has since declined to $171.33, placing it -26.7% below its 52-week high of $233.67, and the company remains unprofitable with net income of $-14,281,000.00 despite strong revenue growth of +82.8%. His cross-ticker track record shows only 1 prior sell across all holdings with a 90-day well-timed rate of 0.00%, and that prior AAOI-specific sale on 2026-03-09 returned +78.4% in 90 days—meaning the stock rose after his sale, indicating poor timing on that prior trade. Against the backdrop of negative earnings and a stock that has retraced significantly from recent highs, this second insider reduction may warrant examination of whether a larger portfolio shift is underway.

CFO Murry Stefan J. sells 33,000 AAOI shares at $173.26 for $5.7M, retaining 451.9K shares; stock down 26.7% from 52-week high despite 90-day surge of +294.4%.

Murry Stefan J., Chief Financial Officer of Applied Optoelectronics, executed a sale of 33,000 shares at $173.26 on 2026-05-19, reducing his holdings by 6.8% to 451,906 shares (451.9K shares) while realizing $5,717,580.00 ($5.7M). The sale occurred against a backdrop of significant recent gains: the stock is up 30-day change: +7.5% and 90-day change: +294.4%, though it remains 26.7% below its 52-week high of $233.67. His prior five sales at AAOI show a consistent pattern: across the 90-day window post-sale, returns have been positive (ranging from +8.6% to +274.7%), meaning the stock rose after he sold, indicating these transactions were not well-timed as a group (a 0% well-timed rate at the 90-day mark across the same ticker). The company's recent financial position shows annual revenue growth of +82.8% with a market cap of $13.7B, but unprofitability persists: the latest quarter posted net income of $-14.3M on revenue of $151.1M, and full-year net income was negative. The present transaction warrants monitoring in light of the CFO's prior AAOI sales pattern and the company's ongoing unprofitability despite strong topline growth.

CEO Thompson sold 58,000 shares at $173.26 for $10.0M; stock now -26.7% from 52-week high, company unprofitable despite +82.8% YoY revenue growth

Lin Chih-Hsiang (Thompson), the President and CEO, sold 58,000 shares (58.0K shares) at $173.26 on 2026-05-19 for $10,049,080.00 ($10.0M), reducing his holdings by 2.5% to 2,255,693 shares (2.26M shares). This substantial open-market sale by the company's chief executive comes as APPLIED OPTOELECTRONICS (AAOI) stock has declined -26.7% from its 52-week high of $233.67, though it remains +7.5% over 30 days and +294.4% over 90 days. The company reported $151,144,000.00 ($151.1M) revenue in the latest quarter with annual revenue growth of +82.8%, but posted a net loss of $-14,281,000.00 ($-14.3M)—reflecting ongoing unprofitability despite strong top-line growth. Thompson's cross-ticker track record shows 14 prior open-market buys with an 88.89% 90-day win rate, establishing a pattern of favorable timing execution, while his 5 prior trades specifically at AAOI (all buys on 2025-08-13 and 2025-08-14) were all well-timed at the 90-day mark, though this sell represents a notable directional shift from that prior accumulation pattern.

Kuo David C sold 19,227 shares of AAOI at $173.26 ($3.3M); stock down 26.7% from 52-week high yet up 294.4% in 90 days.

Kuo sold 19,227 shares at $173.26 on 2026-05-19, reducing holdings from 216,597 to 197,370 shares (-8.9%). The current price of $171.33 is 26.7% below the 52-week high of $233.67, yet the stock has gained 294.4% over the past 90 days, suggesting the sale occurred during a steep rally. His prior three sales at AAOI (Feb 10, Feb 11, Mar 19) each showed positive 90-day returns (112.4%, 93.0%, and 59.2% respectively), meaning none of these prior sales preceded stock declines at the 90-day mark. The company remains unprofitable with net income of $-14,281,000.00 on revenue of $151,144,000.00, though annual revenue growth was +82.8%, creating tension between near-term profitability and growth metrics.

Chang Hung-Lun (Fred) sold 33,630 shares of AAOI at $173.26 on 2026-05-19; current price $171.33 reflects -26.7% from 52-week high of $233.67.

Chang Hung-Lun sold 33,630 shares (7.9% of pre-transaction holdings of 425.4K shares) at $173.26, leaving him with 391.8K shares. The sale occurred when AAOI was trading -26.7% below its 52-week high of $233.67, though the 30-day price change shows +7.5% and the 90-day change shows +294.4%. The company generated $151.1M in quarterly revenue but reported net income of -$14.3M, with annual revenue growth of +82.8% against a full-year negative net income backdrop. At a $13.7B market cap, AAOI remains unprofitable despite strong topline expansion.

CFO Murry Stefan J. sells 4,000 shares of AAOI while stock trades near 52-week highs; his 6th open-market sale at this ticker in three years.

CFO Murry Stefan J. sold 4,000 shares—his sixth open-market sale at AAOI in the past three years—while the stock trades near its 52-week highs after a steep surge. This continues a pattern of consistent selling: the insider has made 25 open-market sales across all his holdings in the 36-month window, with zero open-market purchases, suggesting a disciplined approach to rebalancing rather than panic. The timing is notable: his prior sales at this company have shown mixed short-term results but all poor long-term timing at the 90-day horizon, as the stock has consistently risen after each exit. Applied Optoelectronics remains unprofitable and burning cash despite strong revenue growth, adding nuance to the valuation picture at current prices. The stock's dramatic near-term appreciation may reflect speculative momentum rather than fundamental improvement, making this a case where an executive's exit warrant closer attention to fundamentals.
