AST SpaceMobile Inc. (NASDAQ:ASTS) announced a proposed offering of $1 billion in convertible senior notes due 2034, with an option for an additional $150 million. The move comes as the company disclosed a preliminary cash and restricted cash balance of $2.723 billion as of June 30, down 21.3% from $3.459 billion at the end of March. The stock closed regular trading down 3.7% at $66.31 and tumbled a further 13.5% to $57.35 in after-hours trade.
The notes, which will mature on February 1, 2034, can be converted into cash, Class A common stock, or a combination thereof. The coupon rate and conversion premium have yet to be determined. Proceeds from the offering are intended to fund capped call transactions, which are designed to limit dilution or additional cash payments upon conversion, though only up to a certain point. The company also indicated that remaining funds could be used for general corporate purposes, including expansion, securing additional orbital access, or potential partnerships and acquisitions aimed at reducing reliance on external launch providers. However, AST SpaceMobile stated that no definitive agreements are currently in place for any such transactions.
The sharp decline in cash reserves during the second quarter—a drop of approximately $735.9 million—underscores the company's need for additional capital as it advances its satellite deployment plans. The base $1 billion offering would, on a pro forma basis, restore gross cash and restricted cash to roughly $3.723 billion before deducting offering expenses, capped call costs, and any subsequent cash flows. If the full $150 million option is exercised, that figure would rise to about $3.873 billion.
AST SpaceMobile's decision to pursue this financing appears closely tied to its revised satellite launch timeline. In May, the company stated it had sufficient capital to build and launch approximately 90 satellites, with 45 to 60 operational units needed to begin service in key markets. At that time, it targeted the end of 2026 for deploying roughly 45 BlueBird satellites. However, in Wednesday's filing, that target was pushed back to early 2027, suggesting the new funding may be directed toward resolving launch and supply chain bottlenecks rather than filling an immediate funding gap for the constellation.
This marks AST SpaceMobile's fifth convertible debt offering since January 2025 and the second $1 billion issuance in five months. Total gross principal from these offerings, including the current proposal, amounts to $4.26 billion. As of March 31, the company had repurchased some of its earlier notes, reducing outstanding convertibles to approximately $2.554 billion. The new $1 billion base deal would increase that figure by about 39%, not accounting for any repurchases or conversions during the second quarter. The 2034 notes will mature between AST's existing 2032 and 2036 issues, spreading out repayment obligations but also adding to the total claims on future cash flows.
In a separate development, AST SpaceMobile disclosed that it is in advanced discussions with Rakuten Group Inc. (TYO:4755) regarding RAST Co. being selected as an indirect subsidy recipient under Japan's J-LEO satellite project. The potential subsidy could reach up to 148 billion yen, or approximately $1 billion. However, the company cautioned that this is not a certainty and investors should not treat it as committed capital.
Despite the additional financing, risks remain elevated. AST will carry more debt before achieving broad commercial service, and the final conversion terms could weigh on the equity. The capped call transactions will also reduce the net cash proceeds. A planned launch acquisition might tie up further capital without immediately resolving timing issues. The company also flagged potential schedule shifts related to satellite assembly, testing, vehicle readiness, and logistics.
The market's reaction suggests skepticism about the near-term benefits. With the stock down sharply after hours, the focus now shifts to the pricing of the notes. A lower coupon, higher conversion premium, and modest capped call costs would signal favorable terms for AST, while softer terms could indicate a more defensive posture. Ultimately, the key metric is not just the $1 billion target but the company's ability to have 45 satellites ready by early 2027 and the spending required to achieve that milestone.
