Core businessRocket Lab operates the Electron small satellite launcher and Space Systems component and spacecraft business, with the Neutron medium-lift rocket in development, serving commercial and government satellite operators globally.AST SpaceMobile is building a space-based broadband cellular network using very large satellites (BlueBird constellation) that connect directly to standard smartphones, aiming to eliminate mobile connectivity dead zones globally without specialized hardware.
Investor focusInvestors track Electron launch cadence and revenue, Space Systems component revenue growth, and Neutron rocket development milestones as the company builds toward medium-lift market entry.Investors track AST SpaceMobile's BlueBird satellite constellation deployment, commercial service launch with MNO (mobile network operator) partners, and revenue ramp from mobile operators paying for access to AST's space-based coverage.
RKLB strengths
  • Established launch track record with Electron as one of the world's most-launched small rockets
  • Diversified revenue from both launch services and space systems components
  • Management credibility from consistently achieving technical milestones in commercial space
ASTS strengths
  • If successful, direct-to-phone satellite broadband addresses a genuinely large global coverage gap affecting billions of people
  • Partnerships with major mobile operators (AT&T, Verizon, Vodafone, Rakuten) validate the commercial concept
  • First mover advantage in large-LEO direct-to-standard-phone satellite service
Risks to watch — RKLB
  • Neutron rocket development represents a significant capital investment and technology challenge
  • Small satellite market competition remains intense
  • Profitability timeline extends as Neutron investment is front-loaded
Risks to watch — ASTS
  • Technology and regulatory complexity for deploying large LEO satellites for direct cell service is enormous
  • Significant capital required for full constellation build-out before commercial revenue scales
  • Competes with SpaceX Starlink's direct-to-cell product and other emerging satellite-to-phone solutions
Frequently asked questions
Starlink requires a dedicated user terminal (antenna dish) to access satellite internet. AST SpaceMobile aims to work with any standard mobile smartphone using existing cellular bands — no specialized hardware needed — which would dramatically expand addressable market reach.
