AST SpaceMobile, Inc. (ASTS) slumps 17% on launch fears
AST SpaceMobile, Inc. (ASTS) slumps sharply after a Blue Origin New Glenn test explosion rattles launch confidence and pressures space stocks. The selloff also follows a Deutsche Bank downgrade, highlighting how launch execution risk can quickly hit a company whose growth depends on satellites reaching orbit on schedule.
AST SpaceMobile, Inc. (ASTS) slumped 17.4% as investors reacted to a Blue Origin New Glenn test explosion that renewed fears about launch timing for the company’s BlueBird satellite rollout. A same-day Deutsche Bank downgrade added pressure, underscoring that ASTS remains a high-risk, milestone-driven stock where launch setbacks can quickly delay revenue growth and compress valuation.
AST SpaceMobile, Inc. (ASTS) slumps sharply on May 29, falling 17.39% to $109.94 as of 11:04 a.m. ET while trading at 1.5x its 200-day average volume. The selloff stands out because it tracks a fresh shock in the launch ecosystem, not a new ASTS operating update, and that matters for a stock priced on deployment milestones more than present-day profits.
Key Takeaways
ASTS is down 17.39% today, with above-average trading activity at 1.5x relative volume.
The clearest catalyst is Blue Origin's New Glenn hotfire-test explosion on May 28, which raised fresh concerns about launch timing for AST SpaceMobile's BlueBird satellite rollout.
ASTS already faced Blue Origin-related execution pressure after BlueBird 7 failed to reach its intended orbit in April 2026.
Financially, AST SpaceMobile remains a build-first story, with Q1 2026 revenue of $14.74M, a net loss of $191.01M, and a reaffirmed 2026 revenue outlook of $150M to $200M.
For investors, today's drop shows that launch-provider risk can hit ASTS as hard as company-specific news because the valuation depends on getting satellites into orbit on schedule.
The most concrete reason for ASTS's decline is the Blue Origin New Glenn test anomaly reported on May 28. News coverage tied the explosion directly to weakness across space stocks on May 29, and ASTS was one of the hardest hit names in that group.
That link is straightforward. AST SpaceMobile depends on launch providers to deploy its BlueBird satellites, and Blue Origin is one of them. AST said in its May 11 business update that it is targeting about 45 BlueBird satellites in orbit during 2026, supported by agreements with multiple launch providers including Blue Origin and SpaceX. When one of those providers suffers a high-profile failure, the market quickly marks down the confidence level around the schedule.
This is not a minor issue for ASTS. The company is building a direct-to-smartphone satellite broadband network, so each launch is part of the core business plan, not a side project. In plain English, no satellites in orbit means no full network buildout, and no full network buildout means the revenue story takes longer to arrive.
There was also a second negative data point today. Deutsche Bank downgraded AST SpaceMobile to Hold from Buy on May 29 and set a $106 target. That call landed after the Blue Origin incident and reinforced the market's concern that launch execution, not just long-term demand, is driving the stock right now.
Why Blue Origin Problems Hit ASTS Harder Than Many Tech Stocks
ASTS trades like a future network operator, but it carries the operational risk profile of a space infrastructure project. That combination can produce violent moves when a key dependency breaks. A software company can miss a milestone and patch the code. A satellite company needs rockets, timing, insurance, and working hardware all lined up at once. The market rarely grants patience when one of those gears slips.
Importantly, investors were already primed for this reaction because Blue Origin-related trouble had surfaced before. In April 2026, BlueBird 7 did not reach its intended orbit after a New Glenn mission anomaly and was reported to have entered a too-low orbit that would de-orbit. That earlier setback made today's New Glenn explosion more than an isolated headline. Instead, it revived a pattern the market already dislikes.
Because ASTS is still in the constellation build phase, launch cadence matters more than quarterly polish. The company can have carrier relationships and a large addressable market, but if launch timing slips, the monetization timeline slips with it. Therefore, today's selloff looks less like panic and more like a repricing of execution risk.

How AST SpaceMobile, Inc.'s Financials Look After the Move
The financial backdrop helps explain why the stock reacts so sharply to operational setbacks. AST SpaceMobile generated $14.74M in Q1 2026 revenue and posted a net loss of $191.01M. It also reaffirmed a 2026 revenue outlook of $150M to $200M. Those numbers show a company still in heavy build mode, where future scale matters far more than present earnings.
Earnings history adds another layer of caution. ASTS missed EPS estimates in six of its last eight reported quarters. Most recently, on May 11, 2026, the company reported EPS of -$0.66 versus a -$0.20 estimate, a negative surprise of 230.0%. That does not explain today's drop by itself, but it does mean the stock entered this event without much margin for error.
Valuation also remains demanding. ASTS carries a market cap of $44.73B despite an EPS figure of -1.8 and a business that is still proving out deployment at scale. That setup can work when milestones keep landing. However, when the launch chain takes another hit, the premium can compress fast.
Volume confirms the seriousness of the move. ASTS was already an active stock, but today's 1.5x relative volume shows broad participation in the selloff. Heavy turnover during a double-digit drop usually means institutions and fast-money traders are both involved, which can deepen the move before calmer valuation work returns.
AST SpaceMobile still has a differentiated concept. The company aims to deliver cellular broadband directly to ordinary smartphones, which gives it a more ambitious consumer angle than many satellite peers. It also has multiple launch-provider relationships, which matters because diversification is the obvious defense when one provider stumbles.
Still, today's decline shows where the market draws the line. Investors are willing to fund a bold space network story, but they want evidence that deployment can stay on track. The combination of a fresh Blue Origin explosion, the prior BlueBird 7 mission issue, and a same-day Deutsche Bank downgrade created a clean reason to sell first and ask questions later.
Analyst sentiment is now more mixed than the headline growth story implies. The consensus target sits at $96.25, with a range from $80 to $117. With the stock closing previously at $109.94 before today's slide, that spread shows Wall Street is still debating how much execution risk belongs in the price. In other words, this is not a sleepy telecom name. It is a high-beta buildout story with a long runway and very little tolerance for operational mistakes.
AST SpaceMobile's drop on May 29 looks tied first to Blue Origin's New Glenn explosion and then amplified by a Deutsche Bank downgrade. For investors, the message is simple: ASTS remains a high-upside story, but the stock trades on launch credibility, and today's heavy-volume slump is the market's reminder that space hardware rarely gets the benefit of the doubt.
ASTS is down because a Blue Origin New Glenn hotfire-test explosion renewed concerns about launch timing for AST SpaceMobile’s satellite deployment plans. The selloff was amplified by a Deutsche Bank downgrade to Hold.
+Should I buy ASTS stock now?
The article suggests caution. ASTS remains a high-risk, execution-dependent stock, and today’s drop shows how quickly launch setbacks can pressure the share price.
+Did AST SpaceMobile release bad earnings news today?
No, today’s decline was not driven by a new AST SpaceMobile operating update. The main catalyst was launch-provider risk tied to Blue Origin, not fresh company earnings news.
+What does the selloff mean for ASTS investors?
It means the market is repricing execution risk around satellite launches and deployment timing. For investors, the stock may stay volatile until ASTS shows more consistent progress putting satellites into orbit.
