The Rocket Lab story
Rocket Lab launches rockets and builds satellites and spacecraft components, with its expansion into defense constellations and Iridium communications testing whether a broader space business can generate cash.
Written from Rocket Lab's own filings with the SEC, and rewritten when it publishes a new earnings release. Updated 2026-09-30.

The story in brief
- Orders outpace revenue. Revenue reached $234 million in the quarter to June 2026, up 62% from a year earlier, while backlog rose 137% to $2.36 billion.
- Iridium financing secured. In September 2026, Rocket Lab announced full financing for the pending Iridium acquisition and canceled its bridge facility after completing an equity offering.
- Growth still consumes cash. Revenue grew 52.5% over the last twelve months, but free cash flow was -$371 million and operating margin was -29.1%.
What drives the business
- Rocket Lab has expanded from Electron launches into spacecraft manufacturing, components and mission operations, with $1.3 billion in prime contracts to produce 36 satellites for the Space Development Agency anchoring its defense business.
- Electron completed 75 successful missions through December 2025 for customers including NASA, the National Reconnaissance Office and Synspective, while Neutron is being developed for larger constellation deployments.
- Space Systems accounted for 81% of revenue in the quarter to June 2026, reflecting a business increasingly built around satellites, optical systems, solar power and other spacecraft components rather than launches alone.
- The August 2026 release announced a $397 million U.S. Space Force SB-AMTI contract, including options, for spacecraft launching on Neutron, alongside more than $160 million in contracts to build three geostationary satellites.
- The proposed Iridium acquisition, at an enterprise value of approximately $8.0 billion, would add a global communications network serving more than 2.55 million active subscribers and extend Rocket Lab from building and launching spacecraft into operating its own communications constellation.
What the price assumes
The reverse DCF cannot measure the growth embedded in the price because free cash flow and operating earnings are negative, leaving the valuation dependent on future profits.
At $72.19 per share and a market value of $43.2 billion, Rocket Lab trades at 56.2x sales against revenue growth of 52.5% over the last twelve months and an annual pace of 41.8% over the last three years.
TenQ's sales check requires a multiple under 2.5x, and its cash flow yield check requires above 3%, compared with Rocket Lab's -0.9%, leaving Value at 0 of 6 checks passed.
What could change the story
- The September 2026 financing update superseded the earlier bridge financing concern, but the Iridium acquisition still depends on shareholder and regulatory approvals and other closing conditions.
- Iridium's amended $1.775 billion credit facility carries a parent guarantee from Rocket Lab USA, so eliminating the bridge does not eliminate the combined company's debt obligations or constraints on financial flexibility.
- The completed equity offering raised approximately $1.944 billion in gross proceeds through 29.3 million shares, securing acquisition funding while expanding the share base.
- Rocket Lab passed 1 of 6 Quality checks, with negative operating profitability and -$371 million in free cash flow over the last twelve months showing that revenue growth has not yet made the business cash generating.
- Neutron had not flown by the August 2026 release, and its tank rupture during qualification testing in January 2026 underscores the execution risk behind contracts that depend on the new rocket.
What to watch next
- For the third quarter of 2026, management expects revenue between $250 million and $265 million, with GAAP gross margins between 29% and 31%.
- Guidance also calls for GAAP operating expenses between $143 million and $149 million and an adjusted EBITDA loss between $17 million and $23 million, making margins, spending and cash use important measures of backlog conversion.
- The August 2026 update placed Neutron's planned delivery to the launch pad in the fourth quarter of 2026, so subsequent releases should distinguish hardware testing and pad readiness from an inaugural flight.
- For Iridium, the next milestones are closing approvals and progress toward the company's expected completion in the middle of 2027, rather than securing acquisition financing.
