AST SpaceMobile has announced plans to offer $1 billion in convertible senior notes due 2034 through a private placement to qualified institutional buyers.
The company also expects to grant the initial purchasers an option to buy up to an additional $150 million of notes. The option would be available for settlement during a 13-day period beginning on the initial issuance date.
If the additional notes are fully purchased, the offering could reach an aggregate principal amount of $1.15 billion.
The transaction remains subject to market conditions and other factors. AST SpaceMobile has not yet finalized the interest rate, initial conversion rate or certain other terms of the notes.
The notes will be senior unsecured obligations of AST SpaceMobile and will accrue interest payable twice annually. They are scheduled to mature on February 1, 2034, unless they are converted or repurchased before that date.
Noteholders will be able to convert the securities into cash, AST SpaceMobile’s Class A common stock, or a combination of cash and shares. AST SpaceMobile will determine the form of settlement.
Convertible notes allow companies to raise debt capital while giving investors the potential to participate in future increases in the issuer’s share price. Depending on the final conversion terms and AST SpaceMobile’s stock performance, the notes may eventually be converted into equity.
AST SpaceMobile plans to use the proceeds to pursue growth initiatives and secure additional access to orbit for its planned space-based cellular broadband network.
The company said potential uses could include partnerships or acquisitions that further vertically integrate its operations and reduce the risks associated with depending on third-party launch providers.
AST SpaceMobile does not currently have any agreements or understandings regarding potential strategic transactions connected to the offering.
Securing reliable launch capacity is an important part of the company’s broader deployment strategy. AST SpaceMobile is building a satellite network designed to provide cellular broadband directly to ordinary smartphones without requiring specialized equipment or modifications.
The system is intended to support both commercial and government applications while expanding mobile coverage in areas where conventional terrestrial networks are unavailable, unreliable or economically difficult to construct.
Building the network requires the development, manufacturing and launch of a large constellation of satellites. AST SpaceMobile must also fund ground infrastructure, testing, network integration, regulatory approvals and commercial operations.
Launch availability can affect the timing and cost of satellite deployment. By expanding its access to orbit or reducing its reliance on individual launch providers, the company may be able to improve scheduling flexibility and mitigate potential delays.
The proposed financing could also give AST SpaceMobile additional resources to evaluate investments across its satellite manufacturing and deployment supply chain.
Vertical integration could include owning or controlling more of the technology, manufacturing capacity, launch access or operational infrastructure required to build and maintain the network. However, any future investment or acquisition would depend on available opportunities and the company’s strategic priorities.
AST SpaceMobile intends to use a portion of the offering proceeds to pay for capped call transactions expected to be entered into when the notes are priced.
Capped calls are derivative transactions commonly used alongside convertible debt offerings. They are generally designed to reduce the potential dilution that existing shareholders could experience if convertible notes are exchanged for common stock.
The transactions may also offset certain cash payments that AST SpaceMobile could be required to make above the principal amount of converted notes.
The protection provided by the capped calls will be subject to an upper limit. If AST SpaceMobile’s share price rises beyond that cap, the transactions may not fully offset the dilution or cash obligation associated with the notes.
The capped call transactions are expected to cover the number of Class A common shares initially underlying the convertible notes, subject to customary adjustments.
If purchasers exercise the option for the additional $150 million of notes, AST SpaceMobile expects to use part of those proceeds to enter into corresponding additional capped call transactions. The remaining proceeds would support the same growth and orbital-access priorities as the primary offering.
The financial institutions participating in the capped calls may buy AST SpaceMobile shares or enter into derivatives as they establish their initial hedging positions.
This activity may influence the market price of AST SpaceMobile’s stock or the convertible notes around the time the offering is priced.
These transactions could contribute to movements in AST SpaceMobile’s share price and may affect the value noteholders receive if they convert their securities.
AST SpaceMobile is headquartered in Midland, Texas, and is developing a global space-based cellular broadband network designed to connect directly with standard mobile devices. The company’s technology is intended to deliver 4G and 5G connectivity using satellites that communicate with ordinary smartphones. AST SpaceMobile is targeting a global market that includes nearly six billion mobile subscribers.
The company believes the network could extend broadband access to underserved populations and provide additional coverage for mobile network operators, governments, and emergency-response organizations. Potential applications include rural connectivity, maritime and remote-area coverage, disaster response, public safety, defense communications, and supplemental capacity for existing cellular networks.
The proposed convertible notes offering would provide AST SpaceMobile with additional long-term capital as it moves forward with satellite production, launches, and network commercialization.
