Exhibit 99.1

Rocket Lab Announces Second Quarter 2026 Financial Results: Posts Record Revenue and Record Backlog, Guides To Another Record Revenue Quarter in Q3 2026

Long Beach, California. August 10, 2026 – Rocket Lab Corporation (Nasdaq: RKLB), a global leader in launch services and space systems, today shared the financial results for fiscal second quarter ended June 30, 2026.

Rocket Lab founder and CEO, Sir Peter Beck, says: “Q2 was another fantastic quarter for Rocket Lab, highlighted by record results and massive momentum that has continued well after the close. We achieved a record $234 million in Q2 revenue - up 62% year-over-year and $34 million higher than last quarter’s record - driven by surging demand across all areas of our business. Q2 2026 saw our backlog grow to $2.36 billion – another record – which, combined with new deals in the period since, equates to more than $1 billion1 in new contracts across launch and space systems already entered into in Q3.”

“Alongside this execution, we closed the acquisitions of Mynaric and Motiv and announced our historic deal to acquire Iridium Communications Inc. Together, these moves position Rocket Lab to accelerate our future into space applications by becoming a self-launching, tier-1 space power that will deliver critical communications capability to millions of users worldwide.”

Highlights for the Second Quarter 2026, plus business updates since June 30, 2026.

•Record quarterly revenue of $234 million, a 62% increase YoY.

•Record backlog of $2.36 billion a 137% increase YoY.

•Announced a landmark agreement to acquire Iridium to create a fully vertically-integrated space powerhouse that designs, builds, launches, and operates its own constellations, delivering critical communications capability to millions of users worldwide.

•Secured more than $437 million1 in new launch contracts across its Electron, HASTE, and Neutron launch vehicles during Q2 2026 plus post-quarter signings, expanding Rocket Lab’s total launch backlog to its highest in history with 90+ launches.

•Introduced the Company’s GHOST globally-deployable launch system to support suborbital and orbital launches from anywhere in the world. GHOST’s first location – named Rocket Lab Launch Complex 4 - will be at the Pacific Spaceport Complex at Kodiak, Alaska, with two pads to be established for high-frequency, launch campaigns. The system is set to make its operational debut with a suborbital launch from Alaska in 2027.

•Achieved critical milestones across Neutron’s assembly, integration, and testing of first-flight hardware as Rocket Lab progresses toward the inaugural launch of its medium-lift reusable rocket. Production of the Stage 1 tank is currently aligned with the target delivery of Neutron to the launch pad in Q4 2026.

•Awarded a $397 million1 contract to deliver multiple Flatellite spacecraft to launch on Neutron for the U.S. Space Force’s Space-Based Airborne Moving Target Indicator (SB-AMTI) program: a critically-important mission for national security detect, track, and monitor airborne threats from space. Rocket Lab is one of only two vendors delivering launch-plus-spacecraft for SB-AMTI: a compelling recognition of the value of Rocket Lab’s strategic vertical integration.

•Awarded more than $160 million across two contracts to build three geostationary satellites. The deals include a prime contract with the Space Force’s Space Systems Command to build and operate two satellites for space domain awareness, representing Rocket Lab’s first foray into geostationary satellite production and operation for the U.S. Government.

1 Includes options across various contracts.

MEDIA RELEASE

•Formally established Rocket Lab Germany GmbH to support potential future scaling of Rocket Lab satellite and component manufacturing in Germany and provide commercial and sovereign space capabilities to European customers.

Third Quarter 2026 Guidance

For the third quarter of 2026, Rocket Lab expects:

•Revenue between $250 million and $265 million.

•GAAP Gross Margins between 29% and 31%.

•Non-GAAP Gross Margins between 35% and 37%.

•GAAP Operating Expenses between $143 million and $149 million.

•Non-GAAP Operating Expenses between $121 million and $127 million.

•Interest Income, net $21 million.

•Adjusted EBITDA loss of between $17 million and $23 million.

•Basic Weighted Average Common Shares Outstanding of 641 million, including approximately 41 million of Series A Convertible Participating Preferred Shares.

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 Q3 2026 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 $18 million to $20 million in Q3 2026.

Conference Call Information

Rocket Lab will host a conference call for investors at 2 p.m. PT (5 p.m. ET) today to discuss these business highlights and financial results for our second quarter, other updates, and to provide our outlook for the third quarter 2026.

The words “believe,” “may,” “will,” “estimate,” “potential,” “continue,” “anticipate,” “intend,” “expect,” “strategy,” “future,” “could,” “would,” “project,” “plan,” “target,” and similar expressions are intended to identify forward-looking statements, though not all forward-looking statements use these words or expressions.

MEDIA RELEASE

Use of Non-GAAP Financial Measures

We supplement the reporting of our financial information determined under Generally Accepted Accounting Principles in the United States of America (“GAAP”) with certain non-GAAP financial information. The non-GAAP financial information presented excludes certain significant items that may not be indicative of, or are unrelated to, results from our ongoing business operations. We believe that these non-GAAP measures provide investors with additional insight into the company's ongoing business performance. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. We encourage investors to review our financial statements and publicly filed reports in their entirety and not to rely on any single financial measure. Reconciliation of the non-GAAP financial information to the corresponding GAAP measures for the historical periods disclosed are included at the end of the tables in this press release. We have not provided a reconciliation for forward-looking non-GAAP financial measures 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. The following definitions are provided:

Adjusted EBITDA

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA further excludes items of income or loss that we characterize as unrepresentative of our ongoing operations. Such items are excluded from net income or loss to determine Adjusted EBITDA. Management believes this measure provides investors meaningful insight into results from ongoing operations.

Other Non-GAAP Financial Measures

Non-GAAP gross profit, gross margin, research and development, net, selling, general and administrative, operating expenses, operating loss and total other income (expense), net, further excludes items of income or loss that we characterize as unrepresentative of our ongoing operations. Such items are excluded from the applicable GAAP financial measure. Management believes these non-GAAP measures provide investors meaningful insight into results from ongoing operations.
