The usual story isn’t just about the selloff. The bigger thing is what investors are now putting up against an old factory plan. Applied Optoelectronics filed an 8-K on Wednesday, announcing a design-build deal with LCC3 Solution Inc. for the OMD 3 (FAB4) cleanroom in Houston. The contract covers everything from design, engineering and procurement to construction, testing, commissioning and closeout.
The project covers 195,591 square feet for ISO Class 6 cleanrooms, 36,500 square feet of office space, and 73,780 square feet set aside for shipping, receiving, testing, and inventory. The contract totals about $94.1 million. Payments are set up monthly and depend on progress, with 10% retainage, according to the filing.
| FAB4 measure | Value | Investor read |
|---|---|---|
| Contract size | $94.1 mln | That’s roughly 1.1% of the latest market cap |
| Cleanroom space | 195,591 sq ft | Works out to about $481 per cleanroom sq ft |
| Total listed space | 305,871 sq ft | Comes to about $308 per listed sq ft |
| Contract vs March 31 cash | 21% | Material size, but not a stretch for the balance sheet |
| Contract vs Q1 revenue | 62% | Large for a single build project |
| Thursday market-value loss | About $1.7 bln | Roughly 18 times the contract figure |
AAOI is getting a capacity trade right now, so the numbers count. The company ended March 31 with $449.4 million in cash, cash equivalents and restricted cash. First-quarter revenue came in at $151.1 million. AAOI guided Q2 revenue to a range of $180 million to $198 million.
The filing sets out milestone dates for the project. Key dates are Oct. 5 for cleanroom enclosure, Oct. 20 for mechanical, electrical and piping, Oct. 31 for mechanical completion, Nov. 30 for performance testing and Jan. 10, 2027 for substantial completion. Late delivery triggers up to $4.9 million in delay damages. If the contractor meets all timing, validation and warranty goals, incentives can total around $15.8 million.
Dr. Thompson Lin, who is AOI’s founder, president and CEO, said in May the company was seeing “strong customer engagement” for its 800G and 1.6 Tb products. He said AOI expected a “strong volume ramp” for 800G starting in Q2. CFO Stefan Murry said AOI had just posted its “fourth consecutive quarter of record revenue” and ended Q1 with capacity for “nearly 100,000 units of 800G transceivers per month.” Applied Optoelectronics, Inc.
The stock dropped more than other optical-networking stocks and the main tech ETF around the same time.
