Rocket Lab (NASDAQ: RKLB) and AST SpaceMobile (NASDAQ: ASTS) both reported Q2 2026 earnings on August 10, 2026, and both stocks have since taken a significant hit.
The two companies share a “SpaceX disruptor” label, but their business models, revenue profiles, and risk levels are fundamentally different from one another.
Rocket Lab posted $234.07 million in revenue for the quarter, representing 62.0% year-over-year growth driven largely by its Space Systems segment.
Space Systems contributed $189.5 million following the closing of the Mynaric and Motiv deals, helping push the company’s backlog to a record $2.36 billion, up 137%.
CEO Peter Beck called it “another fantastic quarter,” and the underlying numbers offer little reason to argue with that characterization.
AST SpaceMobile reported $31.52 million in revenue, missing analyst consensus by 8.36%, while posting a GAAP loss of -$0.77 per share after a $125.9 million charge tied to the BB7 launch incident.
Despite the financial hit, AST’s constellation now holds 13 spacecraft with roughly 20,000 square feet of aperture, as the company pushes toward commercial readiness.
CEO Abel Avellan stated the company is “preparing to initiate beta services with select strategic partners,” signaling that the path to revenue generation remains intact.
Rocket Lab’s longer-term growth strategy centers on vertical integration, including an announced Iridium acquisition that adds 66 satellites, 2.5 million subscribers, and more than $870 million in annual revenue.
The company’s Neutron rocket, priced at a $50 to $55 million average selling price, is targeting a Q4 2026 pad delivery, though Beck acknowledged “the window for an end-of-year launch is narrowing.”
AST SpaceMobile is pursuing a single, large-scale ambition: direct-to-smartphone broadband connectivity delivered from low Earth orbit, with more than 60 mobile network operator partners covering 3 billion potential subscribers.
The company has also secured a preliminary $1 billion J-LEO award with Rakuten in Japan, and its Block 2 satellites are targeting peak data rates of approximately 200 Mbps.
With Q2 capital expenditures hitting roughly $610 million, AST’s cash runway remains a closely watched variable for investors evaluating the stock’s risk profile.
RKLB has fallen 22.56% over the past month, while ASTS has dropped 16.36%, meaning both names now carry a higher bar for execution before sentiment shifts back in their favor.
Rocket Lab’s $397 million Flatellite award further illustrates deepening defense demand, adding a layer of revenue stability that AST has not yet established at comparable scale.
Rocket Lab fits the profile of a compounder with real revenue, growing backlog, and expanding defense exposure, while AST SpaceMobile remains a high-variance moonshot with enormous upside if beta services convert into commercial contracts.
For diversified investors seeking space sector exposure, Rocket Lab currently offers the more balanced risk-reward profile, with AST serving as a speculative position sized accordingly.
