Applied Optoelectronics (AAOI) Reports Thursday. One Customer Owes It $223 Million, or 74.5% of the Entire Receivables Book, and It Sells Cable Gear.
AAOI closed Monday up 16.85% and was indicated 20% higher pre-market Tuesday, ahead of Thursday's Q2 print. Last quarter it burned $143.6 million of cash on $151.1 million of revenue, and 44.1% of that revenue came from a cable-TV distributor.
Applied Optoelectronics reports second quarter results after the close on Thursday, August 6. The stock closed Monday at $110.21, up 16.85% on the day, and was indicated at $132.62 in Tuesday pre-market trading as of 7:55 a.m. Eastern, another 20.33% higher. The 52-week range is $18.50 to $233.67. Nothing was filed with the SEC on Monday or Tuesday morning. No press release went out. The move is the optics complex re-rating on AI networking demand, and AAOI is the highest-beta way to express it.
That beta is not an exaggeration. Between July 23 and July 29 the stock fell from $112.02 to $76.52, down 31.7% in four sessions. Between July 29 and August 3 it rose 44.0%. Average daily volume is roughly 11.3 million shares against 80.2 million outstanding. In July, Tradr launched a dedicated 2X inverse ETF on the name. When a fund company builds a product specifically to short one mid-cap stock, that tells you something about the tape.
The story underneath the tape is genuinely good. Applied Optoelectronics makes optical transceivers, the modules that let servers in an AI cluster talk to each other over fiber. Demand for the 800G and 1.6T versions of those modules is the bottleneck in every hyperscale buildout in the country. In March the company announced its first volume order for 1.6T transceivers, worth more than $200 million, from a long-standing hyperscale customer, with shipments beginning early in the third quarter. In Q1 it completed its first volume shipment of 800G product to a large hyperscale customer. On the May 7 earnings call, CFO Stefan Murry told analysts the company now expects "over $1.1 billion in revenue this year," against $455.7 million in all of 2025. Founder and CEO Thompson Lin said internal demand signals point to $1.2 billion to $1.5 billion, and that $1.1 billion was simply the number management felt confident committing to.
The capacity plan behind that guidance is easy to underrate. AOI exited Q1 producing roughly 100,000 units per month of combined 800G and 1.6T transceivers. Murry told the call the company expects to approach 150,000 per month in Q2, "over 650 thousand pieces" per month by the end of 2026, and "over 930 thousand pieces" per month by the end of 2027. He then put a revenue number on the far end: by mid-2027, roughly $471 million per month of data center transceiver revenue. That is a $5.7 billion annualized run rate from a company that did $151.1 million last quarter.
To get there, the company has been buying and building at a pace that shows up in the filings almost weekly. On April 7 it agreed to buy two Pearland, Texas properties totaling roughly 388,133 square feet for $58,428,612. On May 8 it signed three Houston industrial leases covering 736,216 square feet, with purchase options aggregating $102,250,000. On June 11 its China subsidiary doubled a Shanghai Pudong Development Bank credit line from RMB 250 million to RMB 500 million. On June 25 it signed a $94.1 million design-build contract for a 195,591 square foot ISO Class 6 cleanroom, targeted for completion on January 10, 2027.
So the consensus setup going into Thursday is straightforward. Guidance is revenue of $180 million to $198 million and non-GAAP earnings per share of a $0.03 loss to $0.03 of income on approximately 80.7 million shares. A record quarter is close to a formality. The revenue line will be up more than 50% year over year. The stream is watching that number.
The stream is watching the wrong number.
Applied Optoelectronics filed its Q1 10-Q on May 7. Inside it are two disclosures that decide far more about the next two quarters than the revenue print does. One of them is on the cash flow statement. The other is a customer concentration footnote that most of the people buying this stock at $132 have not read.
The rest of this briefing is for paid members: the full Q1 cash bridge and what it implies for the balance sheet on Thursday, the identity and size of the receivable that is 74.5% of the entire book, the exact revenue level at which this company covers its own operating expenses, the dilution ledger since February 2025 including the convertible that is now deep in the money, and three scenario price zones with the arithmetic behind each.
