Rocket Lab Announces First Quarter 2026 Financial Results: Surpasses All Guidance Metrics Including Revenue, Margin, and Adjusted EDITDA; Posts Record $200M Quarterly Revenue and over $2.2B Backlog; Guides Another Record Revenue

Long Beach, California. May 7, 2026 – Rocket Lab Corporation (Nasdaq: RKLB), a global leader in launch services and space systems, today shared the financial results for fiscal first quarter ended March 31, 2026.

“Rocket Lab has delivered another exceptional quarter with record financial performance of more than $200 million in revenue, consistent execution across launch and space systems programs, a record number of significant new contracts signed, and strategic acquisitions secured. We exited the quarter with $2.2 billion in backlog and currently have access to more than $2 billion in liquidity, putting us in a very strong position for continued growth and M&A execution.

“Rocket Lab continues to lead on execution and growth. We completed successful orbital launches and hypersonic test missions, introduced new space systems products including the highly sought after Gauss satellite electric propulsion system, have been selected to support the Department of War’s Space Based Interceptor program under Golden Dome for America in partnership with Raytheon, and expanded our leading role in hypersonic test launch with a record contract under the MACH-TB program. We also closed the Mynaric acquisition to establish our first European footprint with Rocket Lab Europe, and entered into a definitive agreement to acquire Motiv, adding Mars-proven robotics heritage to our suite of capabilities, while also insourcing costly and supply-constrained spacecraft components, including solar array drive assemblies and other precision mechanisms and motion control systems. Rocket Lab’s tailwinds are strong. We’re already embedded in the most demanding and significant space programs of our generation and we’re in an incredibly strong position to continue expanding this.”

Highlights for the First Quarter 2026, plus business updates since March 31, 2026.

•Record quarterly revenue of $200.3M, a 63.5% increase YoY

•Record GAAP gross margin of 38.2%

•Record backlog of $2.2B, up 20.2% QoQ

•Record liquidity following completion of at-the-market offering, with access to more than $2 billion in total liquidity strongly positioning the Company for further organic growth and M&A execution

•Record new launch contracts, with 31 new Electron and HASTE contracts signed in Q1, plus five new dedicated Neutron launches signed. Rocket Lab has now sold more launches in Q1 2026 than in the full year 2025, demonstrating strong continued demand and growth for the Company’s extensive launch capabilities. Rocket Lab’s total launch manifest now exceeds 70 contracted missions.

•Completed the acquisition of Mynaric AG, a leading provider of laser optical communications terminals for air, space, and mobile applications which further strengthens Rocket Lab’s extensive capabilities as a supplier of satellite components at scale to the global space market.

•Signed a definitive agreement to acquire Motiv Space Systems, a leader in space robotics, motion control systems, and precision mechanisms for spacecraft. The acquisition will achieve two strategic objectives for Rocket Lab: add Mars-proven robotics capability for advanced planetary and national security missions, and closes a critical gap in Rocket Lab’s vertical integration strategy by bringing in-house costly and supply-constrained satellite components like solar array drive assemblies (SADAs) and other precision mechanisms.

•Selected to directly support the Department of War’s Space Based Interceptor (SBI) program, a critical element of President Trump’s Golden Dome for America, in partnership with Raytheon and others selected for the program. Rocket Lab’s launch and satellite capabilities are both being utilized for SBI, demonstrating the value of the Company’s agile and cost-effective end-to-end space capabilities for the warfighter and positioning the Company to capture significant revenue from what could become the U.S. government’s most important national security program.

•Introduced Gauss, a new electric satellite thruster designed for high-volume production to meet the growing demand for reliable satellite propulsion across commercial and national security constellations.

•Achieved significant milestones across the Neutron program with ongoing integration and readiness of first-flight hardware, continued progress on Archimedes engine qualification, and advancement of the second stage and reusable fairing systems, positioning the medium-lift launch vehicle on track for its debut launch later this year.

Second Quarter 2026 Guidance

For the second quarter of 2026, Rocket Lab expects:

•Revenue between $225 million and
