AAOI’s AI Optics Bet Still Runs Through Cable and Dilution

Applied Optoelectronics booked $191.9 million in second-quarter sales, and 800G modules were only $12.8 million of that. Nasdaq-listed AAOI is the ticker crypto desks keep searching as “AAOI USDT,” a shorthand for USDT-margined stock futures that still do not exist as a dedicated pair on the big crypto stock books.

The 800G ramp is real, and so is the factory spend behind it. The wager those searches are trying to lever is still a two-speed business: cable gear, a handful of buyers, and new shares paying for Texas output.

Second-Quarter Sales Hit $191.9 Million

The Sugar Land, Texas company reported the quarter on August 6, 2026. Sales rose 86.4% from $103.0 million a year earlier and 27% from $151.1 million in the first quarter, the fifth straight record, according to the firm’s second-quarter results and outlook.

Data center products finally took the lead, at $107.7 million, or 56.1% of sales, up 140.4% from a year earlier. Cable television products still contributed $80.6 million, or 42.0%. Telecom added $3.4 million.

GAAP gross margin was 27.7%. Non-GAAP gross margin was 29.8%. On a GAAP basis the firm lost $22.8 million, or $0.28 a share. Non-GAAP net income was $5.5 million, or $0.06 a share. Those two bottom lines are not the same number dressed two ways; stock-based pay, legal items, and tax add-backs sit in the gap.

Q2 2026 SALES BY END MARKET

Chief executive Thompson Lin and finance chief Stefan Murry guided third-quarter sales to $255 million to $290 million. Non-GAAP net income was pegged at $10.1 million to $24.0 million, or $0.11 to $0.26 a share, on about 92.8 million shares. That share count is already larger than the 84.6 million common shares outstanding on August 3, because the EPS math includes dilution the factory tour has not finished issuing.

Cable Gear Still Writes 42% of the Checks

For all of 2025, cable was the bigger book. The annual filing shows CATV at $245.1 million, or 53.8% of $455.7 million in sales, against $195.7 million, or 42.9%, from data center products. Digicomm, the CATV distributor, accounted for 53.1% of 2025 revenue. Microsoft, the largest data-center buyer named in that filing, accounted for 28.8%.

Those two names were 81.9% of the year. The Digicomm and Microsoft revenue shares sit in the risk factors for a reason: the firm says it typically has no long-term contracts and lives on purchase orders. Top-ten customers were 96.6% of 2025 sales.

The mix is shifting in 2026, not vanishing. For the six months ended June 30, Digicomm still represented $147.0 million, or 42.8% of $343.1 million in sales. In the second quarter the top three buyers were 42%, 26%, and 24% of revenue, and the top ten were 99%. Accounts receivable were $314.0 million at quarter-end, and $211.0 million of that was owed by Digicomm.

Lin tied the quarter to both stories at once, 800G modules and 1.8 GHz CATV kits, which is the honest product mix. A trader who types AAOI into a crypto search bar is usually looking for AI cluster bandwidth. A large slice of the cash register is still DOCSIS upgrades at cable operators.

The 800G Line Has to Jump Almost Fivefold

Murry told the August 6 call that 800G sales were $12.8 million in the second quarter, 11.9% of data-center revenue and 6.7% of the whole company. That line more than doubled from the first quarter and rose more than tenfold from a year earlier, from a very small base. He said 800G revenue should grow nearly fivefold in the third quarter, with parts and plant as the brake, and that a first 1.6T product was in qualification with a major hyperscale buyer, with shipments due later in the quarter and more than $70 million of 1.6T sales possible in the fourth quarter.

We forecast that demand will continue to outpace our production capacity through mid-2027. We continue to believe the fundamental drivers of long-term demand for our business remain robust and we are uniquely positioned as a key supplier to the AI, cloud infrastructure, and CATV markets.

Thompson Lin, founder and chief executive, August 6, 2026 earnings release

Murry put current output at about 200,000 units a month and said the firm still expects to be able to make about 650,000 800G and 1.6T pieces a month by year-end. He also kept a full-year 2026 sales picture of about $1.1 billion, limited by supply and plant, not by orders. None of that makes 800G the business yet. It makes 800G the slope the $8.9 billion market cap, based on the $105.36 Nasdaq close on September 11, is already skating on.

THE OUTPUT CEILING LIN AND MURRY ARE BUILDING TO

• Current run: About 200,000 units a month across the plants.
• Year-end 2026 target: About 650,000 800G and 1.6T pieces a month.
• The bind: Lin said demand should stay ahead of output through mid-2027.
• Where chips are born: Laser chips are made in Sugar Land; finished modules also come from Taipei and Ningbo.

The 2025 annual report said 57.5% of that year’s sales were made at the China subsidiary and 38.2% in Taiwan. Management is spending to change that mix. First-half capital spending was $335.1 million, including $169.0 million in the United States, $62.8 million in Taiwan, and $103.3 million in China. Property, plant, and equipment rose to $697.1 million on June 30 from $376.1 million at year-end 2025.

Digicomm, Microsoft, and an Amazon Warrant

Microsoft’s weight is falling as a share of the whole firm because cable grew faster, not because data-center demand rolled over. Microsoft was 43.7% of 2024 sales and 28.8% of 2025. Oracle was a 10% customer in 2024 and was not in that club in 2025.

Amazon is the quiet third leg. On March 13, 2025, Applied Optoelectronics issued a ten-year warrant to an Amazon subsidiary covering 7,945,399 shares at $23.6956. Only 1,324,233 shares vested at signing. The other 6,621,166 vest if Amazon and its affiliates buy $4 billion of product over ten years. For the first half of 2026 the firm cut $2.1 million against $84.8 million of warrant-linked sales, which is how the accounting turns a customer’s equity kicker into a contra-revenue item.

WHO HOLDS THE ORDER BOOK

• 2025 filing: Digicomm 53.1%, Microsoft 28.8%, top ten 96.6% of sales.
• Q2 2026: Top three buyers 42%, 26%, and 24%; top ten 99%.
• Receivables: Digicomm owed $211.0 million of $314.0 million at June 30.
• Amazon: Warrant on 7,945,399 shares, $4 billion of purchases to vest the rest.

The quarterly report is blunt about the other side of that concentration: the company has no purchase commitments longer than one year. A missed quarter at Digicomm or a delayed 800G slot at a hyperscaler is not an overlay. It is the P&L.

New Shares Are Paying for the Texas Build

The plants are not being funded by operations. First-half cash used in operations was $73.8 million. Cash used in investing was $633.7 million. Cash from financing was $980.3 million. The June cash and share count shows $499.7 million in cash, up from $206.1 million at year-end 2025, sitting next to an accumulated deficit of $527.1 million.

Common shares went from 75.0 million at December 31, 2025, to 84.4 million at June 30 and 84.6 million as of August 3. Additional paid-in capital rose $968 million in six months. The first at-the-market program, raised to $500 million and finished on April 2, sold about 4.8 million shares at a $103.51 weighted average for about $490 million net. A second program of up to $600 million opened on May 14. A third $600 million program was filed in late August, and the stock sold off on that news before settling near $105.

On August 31 the company signed 10-year leases on two Houston buildings totaling 1.09 million square feet, with a purchase option of $146.6 million. That space is the physical form of the 650,000-unit target. It is also why the share count in the third-quarter EPS guide already assumes more paper than the August 3 register.

THE 2026 FUNDING CALENDAR

1. March 13, 2025: Amazon warrant covers 7,945,399 shares at $23.6956, with most vesting on $4 billion of purchases.
2. April 2, 2026: First ATM completes, about 4.8 million shares and about $490 million net.
3. May 14, 2026: Second ATM of up to $600 million opens.
4. August 6, 2026: Q2 print and $255 million to $290 million third-quarter sales guide.
5. Late August 2026: Third $600 million ATM is filed; the stock sells off.
6. August 31, 2026: Houston Phase II leases add 1.09 million square feet.
7. September 11, 2026: Shares close at $105.36, a market value of about $8.9 billion.

The tape since that August filing has been a $100 to $115 range, not a melt-up. Demand for 800G is not the argument people are having. The argument is how much equity the next million units will cost existing holders.

Chinese Module Makers Were Not Put on the List

Lin has described Applied Optoelectronics as the largest U.S. maker of AI transceivers, and the Sugar Land laser line is the part of that claim that is easiest to defend. The volume ranking is someone else’s. Counterpoint’s Neil Shah puts Innolight’s 27% datacom share at the top of global data-center transceiver revenue, with Coherent at about 17% and Eoptolink close behind. Chinese module makers, including Innolight, Eoptolink, Accelink, and Source Photonics, account for about 60% of datacom transceiver revenue and nearly two-thirds of units.

A Western-only restock is slow. Counterpoint’s note said Coherent and Lumentum do not have the clean rooms, packaging lines, and yields to absorb Innolight and Eoptolink volume inside 12 to 24 months. That is the spare-capacity problem hiding under every “U.S. supplier wins a China ban” slide.

The ban, for now, did not arrive. The FCC equipment authorization final rule, published September 11, 2026 and effective October 13, closes a loophole on logic-bearing parts from firms already on the Covered List. It does not add finished optical transceivers as a class, and Innolight and Eoptolink were not placed on that list. Innolight’s Shenzhen listing rose about 4% on the print.

WHERE THE OPTICS CALL SPLITS

• Management: Lin and Murry say 800G and 1.6T demand already exceeds the plants through mid-2027, so the constraint is output, not orders.
• B. Riley: A July note argued Amazon’s RNG fabric and OpenAI’s MRC protocol flatten networks and could cut structural transceiver counts 40% to 50%, with AAOI more exposed because Amazon and Oracle sit on the 800G and 1.6T ramp.
• Network engineers: Julien Martin-Prin, a network analyst and former AWS engineer, called the RNG-as-AI-risk reading wrong, saying RNG does not sit in the training clusters that eat 800G.

Both the bull factory tour and the flattening note can be true at once for a quarter or two. Hyperscalers can keep buying every 800G module the Texas and Taipei lines can test, while the long-run transceiver-per-GPU ratio is the thing a $8.9 billion price is pretending to know.

What an AAOI USDT Contract Would Price

The search string is a tell. Crypto-native desks want the gap days around earnings, the short side, and USDT margin without a prime broker. A dedicated AAOI perpetual would price those gaps. It would not invent a cleaner business than the 10-Q.

Stock-style exposure on crypto rails is no longer a thought experiment. Some large venues are already crypto rails listing thousands of US stocks, which is the same itch as “AAOI USDT” without single-name optics leverage. Broad Nasdaq-100 futures remain a different bet: they own Microsoft and Nvidia weighting, not Digicomm receivables and a Sugar Land burn-in line.

WHAT THAT PAIR WOULD TRANSMIT

• Session gaps: Almost all price discovery is in U.S. cash hours, so a 24-hour perpetual would gap on every print.
• Customer risk: Two or three purchase-order books can move the name more than the 800G slide.
• Share count: ATM supply and the Amazon warrant are part of the float the contract would track.
• China mix: A Covered List surprise would re-rate the U.S. plant story; September 11 showed the opposite print.

Third-quarter sales guidance of $255 million to $290 million, and a mid-2027 sold-out plant, are the facts the bull case actually owns. The rest of the ticker is cable invoices, a $4 billion Amazon option, and the next block of common. That is the contract a USDT book would be settling, if anyone listed it.
