LONG BEACH, Calif. — (BUSINESS WIRE) — February 28, 2023 — Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or “the Company”), a global leader in launch services and space systems, today shared the financial results for its fiscal fourth quarter and full year 2022, ended December 31, 2022.

Rocket Lab founder and CEO, Peter Beck, said: “Rocket Lab set new company records in 2022. It was our busiest launch year yet with nine Electron launches and 100% mission success. We also made significant progress on the development of Neutron with hardware in production, the launch pad and production complex sites selected and under construction, and an engine test stand at NASA Stennis already supporting the Archimedes test program. It was also a terrific year across space systems, with our strategy to become a full-service space company demonstrated with the successful CAPSTONE mission to the Moon for NASA featuring Rocket Lab developed launch vehicle and spacecraft, and further strengthened with the contract award to develop 17 spacecraft buses for MDA to support Globalstar’s new constellation.”

Fourth Quarter 2022 Business Highlights:

• Launched two successful Electron missions in the fourth quarter for General Atomics and the Swedish National Space Agency.
• Selected by NASA to launch the TROPICS (Time-Resolved Observations of Precipitation Structure and Storm Intensity with a Constellation of Smallsats) mission across two dedicated Electron launches to study hurricanes and tropical storms.
• Introduced the Rocket Lab Responsive Space Program to streamline launch on rapid timelines, delivering confidence and resilience to our customers.
• Completed an ocean recovery of Electron’s first stage, progressing the Company’s program to make Electron a reusable rocket.
• Officially opened the Archimedes engine test stand at NASA’s Stennis Space Center and commenced pre-burner ignitor testing, fast-tracking engine testing for the Neutron rocket.
• Completed construction of the first Neutron Production Complex building at NASA Wallops Flight Facility, began production of carbon composite tank structures and commenced construction on the Neutron launch pad.
• Selected to deliver Satellite Operations Control Center for Globalstar Constellation, building on the $143 million contract awarded in February 2022 to design and manufacture 17 spacecraft buses for Globalstar.
• Selected to build solar panels for NASA’s CADRE mobile robot program.
• Delivered final solar panels for NASA Gateway’s Power and Propulsion Element.

Business Highlights Since December 31, 2022:

• Successfully launched the Company’s first mission from Launch Complex 2 at the Mid-Atlantic Regional Spaceport within NASA’s Wallops Flight Facility in Virginia. The mission deployed three satellites for radio frequency geospatial analytics provider HawkEye 360. With the launch, all three of Rocket Lab’s pads have now successfully launched Electron missions.
• Undertaking simultaneous launch campaigns across Launch Complex 1 in New Zealand and Launch Complex 2 in Virginia with two dedicated Electron missions planned to launch within days of each other in March from two continents.
• Bolstered the Company’s existing line of proven satellite components with the introduction of two new high performance satellite components: a 12Nms reaction wheel designed for constellations and the Frontier-X software defined radio designed to provide high speed data for both near Earth and deep space small satellite missions.
• Formally established Rocket Lab Australia to explore opportunities in launch and space systems.
• Neutron launch vehicle in development now eligible to compete for National Space Security Launch Phase 3 missions – the U.S. Space Force’s program intended to provide assured access to space for Department of Defense and other critical U.S. government payloads.

First Quarter 2023 Guidance

For the first quarter of 2023, Rocket Lab expects:

• Revenue between $51 million and $54 million.
• Launch Services revenue of approximately $19 million.
• Space Systems revenue of between $32 million to $35 million.
• GAAP Gross Margins between -5% to -3%.
• Non-GAAP Gross Margins between 7% to 9%.
• GAAP Operating Expenses between $44 million to $46 million.
• Non-GAAP Operating Expenses between $33 million to $35 million.
• Expected Interest Expense (Income), net $1 million.
• Adjusted EBITDA loss of $28 million to $30 million.
• Basic Shares Outstanding of 476 million.

See “Use of Non-GAAP Financial Measures” below for an explanation of our use of Non-GAAP financial measures, and the reconciliation of historical Non-GAAP measures to the comparable GAAP measures in the tables attached to this press release. We have not provided a reconciliation for the forward-looking Non-GAAP Gross Margin, Non-GAAP Operating Expenses or Adjusted EBITDA expectations for Q1 2023 described above because, without unreasonable efforts, we are unable to predict with reasonable certainty the amount and timing of adjustments that are used to calculate these non-GAAP financial measures, particularly related to stock-based compensation and its related tax effects. Stock-based compensation is currently expected to range from $12 million to $13 million in Q1 2023.

Rocket Lab also announces that David Cowan will complete his tenure on Rocket Lab’s Board of Directors this quarter after nine years serving the company.

Rocket Lab would like to thank David for his leadership, guidance, and support as the Company grew from a small start-up to a NASDAQ-listed company and globally recognized leader in space.
