NEW YORK, Dec. 27, 2025, 6:40 a.m. ET — Market closed [1]
Applied Optoelectronics, Inc. (NASDAQ: AAOI) heads into the weekend with investors digesting a sharp Friday decline that stood out even in a quiet, post-holiday tape. AAOI finished the Dec. 26 session at $37.17, down about 9.3%, with extended-hours pricing around $37.02 as of 7:59 p.m. ET. [2]
The broader market context matters: U.S. stocks ended Friday’s low-volume session nearly unchanged, snapping a short rally as traders took profits and “caught their breath” after the holiday, according to Ryan Detrick, chief market strategist at Carson Group, quoted by Reuters. [3]
Below is what the latest 24–48 hours of coverage, analysis, and forecasting says about AAOI—and what investors may want on their radar before the next opening bell.
What happened to AAOI on Friday
AAOI’s move was decisive: shares traded between $41.38 (high) and $37.03 (low) on Friday, closing near the lower end of that range. Volume was roughly 3.8 million shares, below the company’s recent average cited by MarketBeat (about 5.0 million). [4]
In the last 24 hours, AAOI also showed up on Benzinga’s mid-day movers list as a notable decliner during Friday’s session, reflecting the stock’s tendency to swing harder than the market when liquidity is thin and positioning is crowded. [5]
Why did AAOI fall? Here’s what the latest analysis points to
No single company press release hit in the last 24–48 hours that would obviously “explain” Friday’s drop by itself, so most commentary is triangulating from (1) the stock’s recent run, (2) year-end liquidity, and (3) known fundamental debates around AAOI’s data-center ramp.
A fresh Trefis analysis published Saturday frames the selloff as a re-emergence of investor concerns around AAOI’s Q4 outlook, data-center shipment delays, and rising operational costs—and asks whether the move is simply volatility, or a warning about fragility if markets wobble. [6]
Meanwhile, a Seeking Alpha long-form analysis posted Friday argues the market may be under-watching AAOI’s breakout narrative, emphasizing execution risk but highlighting the significance of the company’s 800G progress and the scale implied by management’s capacity targets. [7]
And zooming out: Friday’s overall market had “few catalysts” and light volume, a setup where high-beta names can overreact to incremental selling, per Reuters’ wrap of the session. [8]
The fundamental backdrop: Q3 results, Q4 outlook, and the “shipment delay” thread
The clearest, most citable foundation for the current debate is still management’s most recent earnings communication.
In an SEC-filed press release (Exhibit 99.1) tied to its third-quarter report, Applied Optoelectronics said Q3 2025 GAAP revenue was $118.6 million, with GAAP gross margin of 28.0%, and a GAAP net loss of $17.9 million (or $0.28 per basic share). [9]
On the data-center side, management explicitly acknowledged timing issues. CFO Dr. Stefan Murry said data-center revenue came in “a touch below” expectations due largely to shipping and receiving delays around quarter end. [10]
For Q4 2025, the company guided to:
- Revenue of $125 million to $140 million
- Non-GAAP gross margin of 29% to 31%
- Non-GAAP net income ranging from a loss of $9.0 million to a loss of $2.8 million (loss per share $0.13 to $0.04, using ~70.3 million shares) [11]
Management also positioned 800G as a near-term catalyst. CEO Dr. Thompson Lin said the company was nearing what it believed to be final stages of 800G product qualification and expected “meaningful shipments” in Q4. [12]
Demand catalysts investors are still weighing: 800G volume order and the AI optics roadmap
Two December company announcements remain central to the bull/bear tug-of-war:
1) First 800G volume order from a “major hyperscale customer”
In a Dec. 10 GlobeNewswire release, AOI said it received its first volume order for 800G data-center transceivers from a major hyperscale customer to support AI data-center growth. CEO Dr. Thompson Lin said the company was “pleased to receive our first volume order for our 800G products,” and reiterated that 800G shipments could contribute $4 million to $8 million to Q4 revenue. [13]
The same release included additional color from CFO Stefan Murry, noting the customer had placed orders for nearly $22 million of 400G transceivers year-to-date, including delivery of $13 million worth of those transceivers so far in Q4. [14]
2) New ultra high-power laser aimed at silicon photonics and co-packaged optics
On Dec. 18, AOI announced a 400-milliwatt narrow-linewidth pump laser designed for growing demand tied to silicon photonics and co-packaged optics (CPO) in AI data centers. The company said samples are available to select customers, with volume production expected later in 2026. [15]
In that release, Fred Chang, Senior Vice President and North American General Manager, said AOI had been working “the last several years” on specs for an ultra high-power laser to support future CPO architectures at 800G and beyond. [16]
Forecasts and Wall Street positioning: targets are wide, and that’s the point
Forecast dispersion is unusually large for AAOI—often a sign the market agrees on the opportunity but not on the probability-weighted outcome.
MarketBeat’s compiled view shows:
- Consensus rating: Hold
- Average 12-month price target: $35.60
- High target: $50.00, low target: $15.00
- Rating mix: 4 Buys, 1 Hold, 2 Sells [17]
MarketBeat also lists named analysts tied to recent calls, including Ryan Koontz (Needham & Company) and David Kang (B. Riley) among those reflected in its rating/target history. [18]
On TipRanks, AAOI is shown with a “Moderate Buy” consensus and an average price target around $38.25, with a similarly broad spread (high $50, low $15). [19]
What that means in plain English: the Street is effectively pricing AAOI as a high-volatility execution story—where the upside case depends on scaling data-center shipments (especially 800G) while stabilizing margins and working capital, and the downside case centers on delays, customer concentration, and dilution risk.
Short interest and volatility: the “amplifier” under the price action
AAOI also trades with meaningful short interest. MarketBeat reports that as of Dec. 15, 2025, AAOI had 12.71 million shares sold short, about 19.49% of the public float, with days to cover around 2.5. [20]
High short interest doesn’t guarantee anything—but it can amplify moves in both directions when liquidity is thin and headlines (or even just order flow) hit the tape.
Dilution watch: the $180 million “at-the-market” program is real (and it matters)
One item investors commonly re-check after big moves is whether a company has the ability—and incentive—to raise capital into strength.
Applied Optoelectronics disclosed in an SEC Form 8‑K dated Nov. 7, 2025 that it entered an Equity Distribution Agreement with Raymond James & Associates and Needham & Company allowing the company to issue and sell shares with an aggregate offering price of up to $180 million via “at-the-market” offerings. [21]
ATM programs can be a smart liquidity tool, but they are also a potential dilution overhang, especially for momentum-driven stocks.
What investors should know before the next session
Because it’s Saturday and U.S. exchanges are closed, AAOI won’t have fresh price discovery until trading resumes.
Key practical items to watch before Monday’s open:
- Know the schedule: Nasdaq’s regular session runs 9:30 a.m. to 4:00 p.m. ET, with extended-hours sessions available via broker venues. [22]
- Expect year-end liquidity effects: With just a few trading days left in 2025, market-wide volume can stay choppy. Reuters highlighted lighter volume and limited catalysts in Friday’s tape. [23]
- Be alert for headlines on 800G shipments and customer ramps: The 800G volume order and management’s revenue contribution comments remain core to the thesis debate. [24]
- Watch the holiday calendar: Stocks will be closed on New Year’s Day (Jan. 1, 2026), while New Year’s Eve (Dec. 31) is expected to be a full trading day for stocks, per Investopedia’s schedule coverage. [25]
Bottom line
AAOI’s sharp Friday drop into the weekend is happening at the intersection of three forces: a thin, post-holiday market; a stock with meaningful short interest and high sensitivity to flow; and a company-specific narrative that hinges on execution in high-speed data-center optics.
The next session will likely revolve around whether buyers step back in on the 800G ramp story—or whether the market keeps repricing the risk that shipment timing, margins, and funding needs remain the dominant variables. [26]
