Incoming SpaceX competition

AST SpaceMobile is launching large satellite arrays to provide internet connectivity directly to mobile devices instead of requiring a clunky terminal or large antenna. By partnering with telecommunications providers like AT&T, the company hopes to upsell customers looking for fast internet in places that land-based mobile internet can't reach. Down the line, this technology could start to replace cell tower and wired internet services entirely for customers. With a few satellites already launched, AST SpaceMobile is planning to get between 45 and 60 of its large satellites into orbit in order to start commercial services sometime in 2026.

SpaceX and Elon Musk see the future in AST SpaceMobile and have recently made a giant move to try and enter the direct-to-device market. SpaceX made a $17 billion purchase and a $2 billion commitment to debt payments to take ownership of spectrum licenses owned by EchoStar. This news is what set AST SpaceMobile stock reeling.

A large company and the leader in satellite internet connectivity today, SpaceX will prove a formidable competitor to AST SpaceMobile. However, SpaceX still operates in the terminal-based internet market, which AST SpaceMobile is trying to disrupt. Elon Musk said it will take around two years to get all the systems ready to enable direct-to-device satellite internet, which could take an even longer time given how optimistic Musk generally is on future promises.

If AST SpaceMobile can stick to its current timeline, it may have a few years of runway to try and tackle the direct-to-device market with little competition. Plus, it has many more partners than SpaceX, which today is just partnering with T-Mobile and now EchoStar (owner of Boost Mobile).

Heavy upfront investment, huge addressable market

Building and deploying satellites is not cheap. AST SpaceMobile is generating near zero revenue today and burned $676 million in free cash flow over the last 12 months. In order to fund this upfront spending, AST SpaceMobile has raised a lot of funds, including a recent convertible notes offering of $575 million. As of the latest update, the company had $1.5 billion in cash on the balance sheet, which should give it a funding bridge from now until it starts operating its satellite network.

Once the network is operational, AST SpaceMobile will have a target market in the billions to go after through its telecommunications partners. It will not be targeting users directly but utilizing existing customer relationships through partners such as AT&T, which can upsell the satellite internet service to its millions of customers. These can be day passes or monthly additions to existing subscriber plans.

It is unclear what the exact size of the addressable market will be, but AST SpaceMobile could see rapid revenue growth in the next few years. Management is already guiding for at least $50 million in revenue for the back half of 2025.

The truth about AST SpaceMobile stock

AST SpaceMobile has an exciting business model. If it can get its satellite constellation working properly, the company will have disrupted the terminal-based satellite internet market, giving it a huge opportunity globally. For context, SpaceX's Starlink service is already doing over $1 billion in annual revenue and growing quickly.

However, even with this stock drawdown, it looks like AST SpaceMobile is overvalued. It has a market cap of $14.5 billion compared to a business that is currently generating zero in revenue. Debt is increasing on the balance sheet, while shares outstanding are rising due to capital raises in order to fund the current burn rate. Even if the satellite constellation works as intended, it is unlikely that AST SpaceMobile will generate more than $1 billion in revenue a few years from now, let alone talking about bottom-line profitability.

For all these reasons, AST SpaceMobile stock does not look like a buy after this recent dip.
