The 10-Q filed on November 12 says missed capacity, delivery or Beijing export-permit commitments can turn those deposits into refunds, hitting revenue and liquidity. ## A record quarter, paid for in advance AXT, a Fremont, California compound-semiconductor wafer maker listed on Nasdaq as AXTI, grew September-quarter revenue to $73.4 million from $28.0 million a year earlier, with $54.3 million of it from indium phosphide, the crystal sliced into wafers that carry the lasers inside AI data-center optical transceivers [1][2]. Net income attributable to [AXT](https://theinference.org/markets/companies/axt-inc) was $25.7 million [1]. [Backlog](https://theinference.org/article/axt-s-indium-phosphide-backlog-tops-500-million-five-times-april-s-level-as-revenue-jumps-162), chief executive Morris Young told investors on October 29, is "above $500 million", spanning multiyear agreements, short-term contracts and spot orders [2]. [The 10-Q filed on November 12](https://www.sec.gov/Archives/edgar/data/1051627/000143774926036542/axti20261101_10q.htm) shows what that queue is made of: other people's money [1]. *Chart: **Revenue tripled in the year customers began prepaying** Column chart of AXT quarterly revenue from Q4 2024 to Q3 2026, rising from about $25 million to $73.4 million, with the final quarter highlighted* *Quarterly revenue in US$ millions as reported in AXT's SEC filings, Q4 2024 through Q3 2026. [1][6]* ## The refund clause in the fine print A new risk factor in the filing covers the long-term supply and capacity-reservation agreements AXT signed in 2026 [1][5]. The contracts require about $179.5 million of aggregate advance payments, of which about $92.4 million had been received by September 30; contract liabilities, the line where customer cash waits until wafers ship, jumped from $103 thousand at year-end to $108.2 million [1]. *Chart: **Operating cash flow of $101.7 million passed revenue in Q3 as prepayments arrived** Column chart of AXT quarterly revenue and operating cash flow from Q2 2024 to Q3 2026: operating cash flow is negative in most quarters but jumps to $101.7 million in Q3 2026, above revenue of $73.4 million* *Quarterly revenue and cash from operations in US$ millions as reported in AXT's SEC filings, Q2 2024 through Q3 2026. Customer prepayments arrive as operating cash before the wafers ship. [6]* ## Lumentum wrote the largest check, $43.5 million The largest single deposit so far is $43.5 million from [Lumentum](https://theinference.org/markets/companies/lumentum), the optical components maker, under a capacity-reservation agreement dated July 26, 2026 [1][2]. If AXT misses capacity or delivery commitments, "including as a result of delays in obtaining export permits," customers may terminate and require refunds of the unapplied money, which the filing says could materially and adversely affect liquidity, revenue and pricing [1]. The clause surfaced in [an automated risk alert on November 15](https://www.theglobeandmail.com/investing/markets/markets-news/Tipranks/8842494/axt-inc-faces-revenue-and-liquidity-pressure-from-risks-in-longterm-inp-supply-and-prepayment-agreements/) and has drawn no news coverage [5]. How much of the $500 million backlog sits under refundable deposits is not disclosed; the $293.5 million of remaining performance obligations is the closest marker [1]. ## Beijing holds the switch Every AXT wafer is grown in China by its subsidiary Beijing Tongmei, and each export needs a permit from China's Ministry of Commerce [1]. The same filing says AXT has a backlog of orders for which it has not yet received permits and cannot predict when an application will be reviewed [1]. The refund trigger and the growth story run through the same desk in Beijing. ## A deep cushion, with expiry dates Refunds would land on a balance sheet built to absorb them: $825.9 million of cash, restricted cash and investments at September 30, after an April share sale raised about $632.5 million gross at $64.25 a share [1][2]. ## Nomura's own model has cash flowing out through 2027 Nomura [started coverage on November 3 at Buy with a $90 target](https://exencialrp.substack.com/p/nomura-starts-axt-at-buy-usd90-sees), yet its own model has free cash flow at minus $27 million this year and minus $10 million in 2027, with 2027 earnings 25% below consensus, because reservations fix volume, not price [3]. The fab money has strings too. [Tongmei's October 27 round](https://www.morningstar.com/news/business-wire/20261028553887/axt-inc-announces-up-to-rmb-367-billion-approximately-us545-million-in-private-equity-financing-for-subsidiary-tongmei), at least $285 million and up to $545 million from investors including an affiliate of an existing customer, can be redeemed at cost plus 8% a year if no Hong Kong IPO arrives within three years of closing, and AXT may be handed the note [1][4]. ## December 20, then the contract-liability line Tongmei's subscription agreement terminates if [the minimum has not closed by December 20](https://theinference.org/article/axt-s-record-quarter-is-being-repriced-in-beijing-and-the-clock-runs-out-december-20) [1]. Management counts about $90 million of fourth-quarter revenue as already permitted or requiring no permit [2]. After that, the contract-liability line tells the story: rising means customers still believe, falling means wafers shipped or money went home. The backlog is counted in dollars; the permission to ship it is granted in Beijing, one license at a time. ## Takeaway AXT has taken $92.4 million of customer prepayments, $43.5 million of it from Lumentum, that its 10-Q says customers can demand back if capacity, delivery or China export permits slip. ## Sources 1.
