Rocket Lab Corporation (Nasdaq: RKLB) (“Rocket Lab”, “the Company”, “we,” “us,” or “our”), a global leader in launch services and space systems, today shared the financial results for fiscal second quarter ended June 30, 2025.

Rocket Lab founder and CEO, Sir Peter Beck, said: “Rocket Lab has delivered impressive gross margin expansion and another record revenue result this past quarter, driven by our strong operational performance and program execution that has us on track for a record year of launches and spacecraft delivery. It’s also been a busy quarter of M&A activity as we’ve progressed our acquisition of Geost, strongly positioning ourselves to meet the needs of defense initiatives like the Golden Dome with end-to-end mission solutions across launch, spacecraft - and now payloads. We’re confident our strategic investments will drive new growth opportunities that will drive us toward long-term profitability, particularly as we guide toward another potential record quarter for Q3.

“On the launch side of the business, with five flawless missions executed, Electron maintains its leadership position as the world’s leading small orbital rocket with a rising launch cadence and increasing international demand for its services. We’ve also made steady progress with our reusable medium-lift rocket Neutron, with Launch Complex 3 now largely complete and flight hardware on its way there for first launch – bringing us closer to delivering disruptive competition to the launch industry for our commercial and national security customers.”

Business Highlights for the Second Quarter 2025, plus updates since June 30, 2025.

• Successfully launched five Electron missions across the quarter, including two launches two days apart from the same launch site – a new record from Rocket Lab Launch Complex 1. Another successful launch this week brings Rocket Lab’s total Electron launch count to 69.
• New Electron launch contracts with international space agencies, reflecting the strength of Rocket Lab’s global reputation as a trusted launch provider for both the U.S. and its allies.
• Confirmed Rocket Lab’s Launch Complex 3 - the launch, test, and landing site for its reusable Neutron rocket – is on track to be completed and officially opened in Q3, 2025.
• The creation of a new Payloads business unit that significantly enhances the Company’s position for future defense satellite contracts with its imminent acquisition of Geost, expected to close shortly for $275 million in a cash-plus equity transaction, including a potential time-based revenue earnout of up to $50 million.
• Moved into production of the Company’s $515 million constellation build of 18 spacecraft for the Space Development Agency’s Tranche 2 Transport Layer, following the Agency’s confirmation that Rocket Lab’s spacecraft design, manufacturing approach, and systems architectures meets its mission requirements.

We have not provided a reconciliation for the forward-looking Non-GAAP Gross Margin, Non-GAAP Operating Expenses or Adjusted EBITDA expectations for Q3 2025 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 $16 million to $17 million in Q3 2025.
