AST SpaceMobile Stock Plunges 5% Following $1B Convertible Notes and Share Offering Bombshell

Another day, another dilution play—AST SpaceMobile just announced a double-whammy financing move that sent shareholders scrambling for the exits.

The $1 Billion Question

Convertible notes and direct share offerings—Wall Street's favorite magic tricks for making existing ownership percentages disappear. ASTS is pulling both rabbits out of the hat simultaneously, because why settle for modest dilution when you can go for the full shareholder value evaporation experience?

Market Reaction: Instant Punishment

The 5% drop tells you everything you need to know—investors aren't buying the 'growth capital' narrative. They're seeing their stakes get watered down faster than a cheap cocktail at a finance bro convention. The company's chasing $1 billion in fresh capital, but current shareholders are left wondering when their turn to benefit will come.

Because nothing says 'we believe in our stock' like dumping new shares on the market while telling existing holders to just trust the process. Classic finance theater—watch the stock price slide while management collects their fees for arranging the whole spectacle.

AST SpaceMobile, Inc., ASTS

The company confirmed a $1 billion private offering of convertible senior notes, significantly above the initially planned $850 million. It also revealed a registered direct share offering of Class A common stock, further affecting market sentiment.

$1 Billion Convertible Notes Offering Shifts Market Focus

AST SpaceMobile priced $1.0 billion in convertible senior notes due 2036 in a private placement to institutional buyers. The offering saw a boost from $850 million as demand exceeded expectations, pushing the final amount higher. The notes come with a 2.00% annual interest and mature on January 15, 2036.

The company set the initial conversion rate at 10.3845 shares per $1,000 principal, implying a conversion price of $96.30 per share. That marks a 22.5% premium over the last sale price of $78.61 on October 21, 2025. Noteholders may convert under specific conditions before October 2035 after that until maturity.

AST SpaceMobile may redeem the notes for cash starting January 22, 2029, but only under strict stock price and liquidity conditions. The redemption will occur only if the stock trades at 130% or more of the conversion price for a set period. Additionally, noteholders may demand repurchase upon a fundamental change, as defined by the indenture.

Registered Share Offering and Repurchase of 2032 Notes

AST SpaceMobile priced a registered direct offering of 2 million Class A common shares at $78.61 per share. This offering is scheduled to settle on October 29, 2025, pending customary closing conditions. Proceeds will help fund the repurchase of $50 million of the company’s existing 4.25% convertible notes due 2032.

The company disclosed private agreements with a few existing noteholders to repurchase these notes using proceeds and cash on hand. It may repurchase additional notes after the current transactions close, depending on market and liquidity factors. These moves aim to restructure outstanding obligations while deploying capital for growth.

Holders repurchasing the 2032 notes might enter or unwind equity hedge positions tied to AST SpaceMobile stock. These trading activities could create short-term volatility in both stock and bond pricing. The company acknowledged that market impact is possible, though the long-term effect remains uncertain.

Purpose and Use of New Capital for Satellite Expansion

AST SpaceMobile expects to raise approximately $981.9 million net from the new note offering, excluding potential option exercises. Should underwriters exercise the full $150 million option, net proceeds could increase to $1.13 billion. The company will utilize the funds to support the deployment of its global satellite constellation and other corporate initiatives.

The expansion aligns with AST SpaceMobile’s vision of enabling space-based broadband for mobile phones worldwide. This service targets both commercial and government sectors, positioning the firm as a unique player in telecom infrastructure. The new capital provides a foundation for scaling service in strategic markets globally.

Though the capital raise strengthens financial footing, the stock reacted negatively to the dilution risk and near-term market uncertainties. With the offering now priced and the notes nearing issuance, market attention may shift back to execution and deployment milestones. AST SpaceMobile remains focused on delivering on its long-term growth strategy.
