Overview Rocket Lab is an end-to-end space company with an established track record of mission success. We deliver reliable launch services, spacecraft design services, spacecraft components, spacecraft manufacturing and other spacecraft and on-orbit management solutions that make it faster, easier and more affordable to access space. While our business has historically been centered on the manufacture of small-class launch vehicles and the related sale of launch services, we are currently innovating in the areas of medium-class launch vehicle and launch services, space systems design and manufacturing, on-orbit management solutions and space data applications. Each of these initiatives addresses a critical component of the end-to-end solution and our value proposition for the space economy: •Launch Services is the design, manufacture, and launch of orbital rockets to deploy payloads to various Earth orbits and interplanetary destinations. •Space Systems is the design and manufacture of components and spacecraft program management services, space data applications, mission operations, optical systems, laser optical communications and space robotics. Electron is our orbital small launch vehicle that was designed from the ground up to accommodate a high launch rate business model to meet the growing and dynamic needs of our customers for small launch services. Since its maiden launch in 2017, Electron has become the leading small spacecraft launch vehicle delivering over 250 spacecraft to orbit for government and commercial customers across 87 successful missions through June 30, 2026. In 2025, Electron was the second most frequently launched orbital rocket. Our launch services program has seen us develop many industry-leading innovations, including 3D printed electric turbo-pump rocket engines, fully carbon composite first stage fuel tanks, a private orbital launch complex, a rocket stage that can be configured to convert into a highly capable spacecraft on orbit, and the potential ability to successfully recover a stage from space, providing a path to reusability. In March 2021, we announced plans to develop our reusable-ready medium-capacity Neutron launch vehicle that will increase the payload capacity of our space launch vehicles to approximately 13,000 kg for reusable configuration launches to low Earth orbit and support lighter payloads for higher orbits. Neutron will be tailored for commercial and U.S. government constellation launches and ultimately configurable for and capable of human space flight, enabling us to provide crew and cargo resupply to space stations. Neutron will also provide a dedicated service to orbit for larger civil, defense and commercial payloads that need a high level of schedule control and high-flight cadence. We expect to be able to leverage Electron’s flight heritage across various vehicle subsystems designs, launch complexes and ground station infrastructure. 34 Table of Contents Our space systems initiatives are supported by the design and manufacture of our spacecraft family along with a range of components, software and services for spacecraft, including reaction wheels, star trackers, radios, separation systems, solar solutions, command and control spacecraft software, high voltage space grade battery solutions, optical systems and additional products in development to serve a wide variety of sub-system functions. We entered this market in 2020 with our acquisition of leading spacecraft components manufacturer Sinclair Interplanetary, and have since expanded our market participation with the acquisitions of Planetary Systems Corporation, SolAero Technologies Corp., Advanced Solutions, Incorporated, GEOST LLC (“GEOST”), Mynaric AG (“Mynaric”) and Motiv Space Systems, LLC (“Motiv”). Each of these strategic acquisitions brought incremental vertically-integrated capabilities for our own spacecraft family and also enabled Rocket Lab to deliver high-volume manufacturing of critical spacecraft components and software solutions at scale prices to the broader spacecraft merchant market. Our spacecraft family, which are configurable for a range of low Earth orbit, medium Earth orbit, geosynchronous orbit and interplanetary missions enable us to offer an end-to-end mission solution encompassing launch, full spacecraft manufacturing, ground services, mission operations and optical systems to provide customers with streamlined access to orbit with Rocket Lab as a single mission partner. Recent Developments Neutron Update We continue to make significant progress in the development of the Neutron launch vehicle. Neutron qualification testing from large structures through to component level systems is ongoing. During Q2, we achieved significant milestones across the Neutron program with ongoing integration and readiness of first-flight hardware, continued progress on Archimedes engine testing, and advancement of the second stage and reusable fairing systems. Production of the Stage 1 tank is currently aligned with the target delivery of Neutron to the launch pad in Q4 2026. While the window for an end-of-year launch date is narrowing, we are balancing the schedule of the first launch with entering Neutron into service as a system ready for full-scale production and high-cadence launch beyond flight one. Exact launch timing will also depend on the outcome of first stage qualification and other critical tests occurring later in 2026. Risk and uncertainty remains in the complex development cycle of a new launch vehicle which could impact our current best estimate of a targeted timeline for first launch. Pending Acquisition On June 28, 2026, we entered into a definitive agreement to acquire Iridium Communications Inc. The transaction is subject to customary closing conditions, including regulatory approval, and, if approved, is expected to close in 2027. Additional information regarding the transaction is included in Note 1 – Description of the Business to the condensed consolidated financial statements. Space Force Missile Defense Suborbital Launch Program On July 21, 2026, we entered into an agreement with the U.S. Space Force Space Systems Command’s Rocket Systems Launch Program to execute 12 suborbital launches supporting missile defense programs, with options for up to six additional launches. The contract has a total potential value of $266 million. Space Force Space-Based Airborne Moving Target Indicator Program On July 30, 2026, we entered into an agreement with the United States Space Force to design, manufacture, launch, and operate Flatellite satellites for the Space-Based Airborne Moving Target Indicator program. The contract has a total potential value of $397 million, including options. 35 Table of Contents Key Factors Affecting Our Performance Ability to timely develop and successfully deploy Neutron launch vehicle Our future results will depend on the success of the development and commercial acceptance of our Neutron medium-capacity launch vehicle. While we have made significant progress across Neutron’s structures and infrastructure to date, including engine testing and initial production execution, the commercial development of a new launch vehicle is inherently time consuming and involves numerous risks throughout the engineering and manufacturing development cycle, hardware and systems testing, and infrastructure readiness, any of which could create further delays in reaching the initial launch and future launches of the completed vehicle. In addition, even if we succeed in developing Neutron to a successful initial launch, we could be unsuccessful in developing the ability to produce these launch vehicles in quantities and with the necessary quality manufacturing system that ensures each vehicle and engines perform as required or meet our expectations for future launch cadence. Any delay in the production of the Neutron launch vehicle or in our ability to produce these launch vehicles at our expected rate of production and with a reliable quality management system could have a material impact on customer acceptance as well as our future revenue, financial condition and results of operations. Additional delays or setbacks in Neutron development may require more research, development and capital expenditures than we currently anticipate, which could adversely affect our liquidity and capital resources in future periods. Ability to sell additional launch services, space systems service and spacecraft components to new and existing customers Our results will be impacted by our ability to sell our launch services, space systems services, and spacecraft components to new and existing customers. We have successfully launched Electron 87 times delivering over 250 spacecraft to orbit, including suborbital launches, through June 30, 2026. We have flight hardware and spacecraft with an extensive flight heritage, including legacy missions enabled by Sinclair Interplanetary (acquired April 2020), Advanced Solutions, Incorporated (acquired October 2021), Planetary Systems Corporation (acquired November 2021), SolAero Technologies Corp. (acquired January 2022), GEOST (acquired August 2025), Mynaric (acquired April 2026) and Motiv (acquired May 2026). Our growth opportunity is dependent on our ability to expand our addressable launch services market with larger volumetric and higher mass payload capabilities of our in-development medium-capacity Neutron launch vehicle, which will address large commercial and government constellation launch opportunities. Our growth opportunity is also dependent on our ability to win spacecraft constellation missions and expand our portfolio of strategic spacecraft components. Our ability to sell additional products to existing customers is a key part of our success, as follow-on purchases indicate customer satisfaction and decrease the likelihood of competitive substitution. To sell additional products and services to new and existing customers, we will need to continue to invest significant resources in our products and services. Ability to improve profit margins and scale our business We intend to continue to invest in initiatives to improve our operating leverage and significantly ramp production. We believe continued reduction in costs and an increase in production volumes will enable the cost of launch vehicles to decline and improve our gross margins. Our ability to achieve our production-efficiency objectives could be negatively impacted by a variety of factors including, among other things, lower-than-expected facility utilization rates, manufacturing and production cost overruns, increased purchased material costs and unexpected supply-chain quality issues or interruptions. Government expenditures and private enterprise investment into the space economy Government expenditures and private enterprise investment has fueled the growth in our target markets. We expect the continued availability of government expenditures and private investment for our customers to help fund purchases of our products and services will remain. This is an important factor in our company’s growth prospects. Key Metrics and Select Financial Data We monitor the following key financial and operational metrics that assist us in evaluating our business, measuring our performance, identifying trends and making strategic decisions. 36 Table of Contents Launch Vehicle Build-Rate and Launch Cadence We built approximately 14 Electron launch vehicles in 2024 and approximately 24 Electron launch vehicles in 2025. We built approximately 11 Electron launch vehicles during the six months ended June 30, 2026. We launched 16 Electron vehicles in 2024 and 21 Electron vehicles in 2025. We launched 12 Electron vehicles during the six months ended June 30, 2026. Growth rates between launches and total launch service revenue are not perfectly correlated because our total revenue is affected by other variables, such as the revenue per launch, which can vary considerably based on factors such as unique orbit and insertion requirements, payload handling needs, launch location, time sensitivity of mission completion, method of revenue recognition and other factors. Revenue Growth Three Months Ended June 30, 2026 and 2025 We generated $234.1 million and $144.5 million in revenue for the three months ended June 30, 2026 and 2025, respectively, representing a year-on-year increase in revenue of approximately 62%. This year-on-year increase resulted from space systems revenue growth of $91.6 million, primarily driven by satellite manufacturing and acquisitions, partially offset by a decrease in launch revenue of $2.1 million. Launch revenue declined despite six Electron launch missions completed for the three months ended June 30, 2026 versus five Electron launch missions completed for the three months ended June 30, 2025, primarily due to revenue recognition timing. Two of the six Electron launch missions completed for the three months ended June 30, 2026 were Hypersonic Accelerator Suborbital Test Electron (“HASTE”) launch missions, for which revenue was recognized over time and was partially recognized in prior quarters. All five Electron launch missions completed for the three months ended June 30, 2025 were point-in-time launches. The decrease was partially offset by increased other launch revenue of $5.7 million, which includes contract termination and study revenue. Six months ended June 30, 2026 and 2025 We generated $434.4 million and $267.1 million in revenue for the six months ended June 30, 2026 and 2025, respectively, representing a year-on-year increase in revenue of approximately 63%. This year-on-year increase resulted from space systems revenue growth of $141.3 million, primarily driven by satellite manufacturing and acquisitions, and an increase in launch revenue of $26.0 million. Launch revenue growth was due to a higher revenue per launch on point-in-time Electron launch missions, an increase in other launch revenue of $7.3 million, which includes contract termination and study revenue and revenue recognized on over-time HASTE launch missions. Revenue and Cost Per Launch Revenue per launch represents the average transaction price attributable to launch contract performance obligations during the period in which the launch occurs, regardless of whether the revenue is recognized using the point-in-time or over-time method of revenue recognition. This metric provides insight into general competitiveness and price sensitivity in the marketplace. Revenue per launch can vary considerably, based on factors such as unique orbit and insertion requirements, payload handling needs, launch location, time sensitivity of mission completion and other factors, and as such may not provide absolute clarity with regards to pricing and competitive dynamics in the marketplace. Cost per launch is calculated by taking actual costs of the launch vehicles that occur in the period, regardless of whether the costs were recognized using the point-in-time or over-time method and all period costs in the period of launch. Three Months Ended June 30, 2026 and 2025 For the three months ended June 30, 2026 and 2025, revenue per launch was $9.1 million and $7.9 million, respectively. Meanwhile, cost per launch for the three months ended June 30, 2026 and 2025 was $4.4 million and $5.0 million, respectively. The increase in revenue per launch reflects changes in customer mix and mission complexity during the period in which the launches occurred. Six months ended June 30, 2026 and 2025 For the six months ended June 30, 2026 and 2025, revenue per launch was $9.2 million and $7.5 million, respectively. Meanwhile, cost per launch for the six months ended June 30, 2026 and 2025 was $4.9 million and $5.3 million, respectively. The increase in revenue per launch reflects changes in customer mix and mission complexity during the period in which the launches occurred. 37 Table of Contents Backlog Backlog represents future revenues that we would recognize in connection with the completion of all contracts and purchase orders that have been entered into by our customers but have not yet been fulfilled, excluding any customer options for future products or services that have not yet been exercised. Contracts for launch services and spacecraft builds typically include termination rights that may be exercised by customers upon advanced notice and payment of a specified termination fee. Backlog increased from $1,847.3 million as of December 31, 2025 to $2,355.9 million as of June 30, 2026, of which $1,415.8 million is related to space systems and $940.2 million is related to launch services. The increase was primarily a result of continued bookings and backlog added through acquisitions, partially offset by revenue recognized on contracts during the period. Components of Results of Operations Revenue Our revenues are derived from a combination of long-term fixed price contracts for launch services and spacecraft builds, and purchase order based spacecraft components sales. Revenues from long-term contracts are recognized using either the “point-in-time” or “over-time” method of revenue recognition. Point-in-time revenue recognition results in cash payments being initially accrued to the balance sheet as deferred revenue as contractual milestones are accomplished and then recognized as revenue once the final contractual obligation is completed. Over-time revenue recognition is generally based on an input measure of progress based on costs incurred compared to estimated total costs at completion. Each project has a contractual revenue value and an estimated cost. The over-time revenue is recognized based on the percentage of the total project cost that has been realized. Estimating future revenues and associated costs and profit is a process requiring a high degree of management judgment, including management’s assumptions regarding our future operational performance as well as general economic conditions. Frequently, the period of performance of a contract extends over a long period of time and, as such, revenue recognition and our profitability from a particular contract may be affected to the extent that estimated costs to complete are revised, delivery schedules are delayed, performance-based milestones are not achieved or progress under a contract is otherwise impeded. Accordingly, our recorded revenues and operating profit from period to period can fluctuate significantly depending on when the point-in-time or over-time contractual obligations are achieved. In the event cost estimates indicate a loss on a contract, the total amount of such loss is recorded in the period in which the loss is first estimated. Cost of Revenues Cost of revenues consists primarily of direct material and labor costs, manufacturing overhead, freight expense, depreciation and amortization and other personnel-related expenses, which include salaries, bonuses, benefits and stock-based compensation expense, directly associated with generating revenues. We expect our cost of revenues to increase in absolute dollars in future periods as we sell more launch services and space systems. As we grow into our current capacity and execute on cost-reduction initiatives, we expect our cost of revenues as a percentage of revenue to decrease over time. Because direct labor costs and manufacturing overhead comprise a significant portion of cost of revenues, increasing our production rate resulting in greater absorption of these costs is our most critical cost reduction initiative. Increasing our production rate is a cross-functional effort involving sales and business development, manufacturing, engineering, supply chain and finance. Operating Expenses Our operating expenses consist of research and development and selling, general and administrative expenses. Research and Development, Net Research and development expenses consist primarily of labor, prototype, professional services, materials, facilities and depreciation expense. We intend to continue to make significant investments in developing new products and enhancing existing products, including but not limited to our medium capacity Neutron launch vehicle and spacecraft features and capabilities, as well as expanding our portfolio of spacecraft components and subsystems. Research and development expenses will be variable relative to the number of products that are in development, validation or testing. However, we expect it to decline as a percentage of total revenue over time. 38 Table of Contents Selling, General and Administrative Selling, general and administrative expenses consist primarily of personnel-related expenses for our sales, marketing, supply chain, finance, legal, human resources and administrative personnel, as well as the costs of customer service, information technology, risk management and related insurance, travel, allocated overhead, other marketing, communications, administrative and transaction expenses. We also expect to further invest in our corporate infrastructure and incur additional expenses associated with operating as a public company, including increased legal and accounting costs, investor relations and compliance costs. As a result, we expect that selling, general and administrative expenses will increase in absolute dollars in future periods but decline as a percentage of total revenue over time. Interest Expense Interest expense consists primarily of interest expense on our loan agreements, amortization of debt issuance costs and finance lease interest. Interest Income Interest income consists primarily of interest income on our cash and cash equivalents, marketable securities and customer financing. Gain (Loss) on Foreign Exchange Gain (loss) on foreign exchange relates to currency fluctuations that generate foreign exchange gains or losses on invoices denominated in currencies other than the U.S. Dollar. Other Income (Expense), Net Other income (expense) consists primarily of changes in the fair value of contingent consideration, loss on extinguishment of debt, gain or loss on disposal of assets and accretion of marketable securities purchased at a discount.

Provision for Income Taxes Six Months Ended June 30, (in thousands, except percentages) 2026 2025 $ Change % Change Provision for income taxes $ (3,535) $ (2,125) $ (1,410) 66 % Provision for income taxes increased by $1.4 million for the six months ended June 30, 2026 as compared to the six months ended June 30, 2025. The effective tax rate was (3.9)% for the six months ended June 30, 2026, compared to (1.7)% for the six months ended June 30, 2025. The effective tax rate differs from the federal statutory rate due primarily to a full valuation allowance against our U.S. deferred tax assets, as well as the impact of discrete items that may occur in any given year but which are not consistent from year-to-year. Liquidity and Capital Resources Since inception, we have funded our operations with proceeds from sales of our capital stock, convertible senior notes, term note debt, equipment financing, research and development grant proceeds, and cash flows from the sale of our products and services. As of June 30, 2026, we had $2.1 billion of cash and cash equivalents and $258.1 million of marketable securities. Our primary requirements for liquidity and capital are for investment in new products and technologies, the expansion of existing manufacturing facilities, working capital, debt service, acquisitions of complementary businesses, products or technologies and general corporate needs. Historically, these cash requirements have been met through the net proceeds we received through private sales of equity securities and convertible senior notes, borrowings under our credit and equipment financing facilities, net proceeds received in our business combination, net proceeds received from our ATM Equity Offerings and payments received from customers. We believe that our existing cash and cash equivalents and marketable securities and payments from customers will be sufficient to meet our working capital and capital expenditure needs for at least the next twelve months, although we may choose to take advantage of opportunistic capital raising or refinancing transactions at any time primarily for the purposes noted above. We will continue to invest in increasing production and expanding our product offerings through acquisitions. On June 28, 2026, we entered into a definitive agreement to acquire all outstanding shares of Iridium for $54 per share in a cash and stock transaction. This represents an enterprise value of approximately $8.0 billion. The Iridium Transaction is expected to require over $3.0 billion in cash related to share consideration payments, repayment of certain outstanding Iridium acquisition indebtedness and payment of transaction fees and expenses, and approximately $1.8 billion of additional cash to repay or refinance Iridium term loan indebtedness, if necessary. The transaction is expected to close in 2027, subject to customary closing conditions, including approval by Iridium’s stockholders and regulatory approval. In connection with the definitive agreement, we entered into a commitment letter, as well as related fee letters with Deutsche Bank Securities Inc., Wells Fargo Bank, National Association and Wells Fargo Securities, LLC and Deutsche Bank AG New York Branch, pursuant to which Deutsche Bank AG New York Branch and Wells Fargo Bank, National Association have committed to provide, subject to the terms and conditions thereof, a 364-day senior secured bridge term loan facility in an aggregate principal amount of $3.6 billion. Material Cash Requirements As of June 30, 2026, our total minimum lease payments were $178.5 million, of which $23.6 million is due in the following twelve months. For details regarding our indebtedness and lease obligations as of June 30, 2026, refer to Note 11 and Note 14, respectively, to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. 44 Table of Contents Our capital expenditures for the six months ended June 30, 2026 were $53.1 million. Our future capital requirements will depend on many factors, including our launch cadence, traction in the market with our space systems offerings, the expansion of sales and marketing activities, the timing and extent of spending to support product development efforts, the introduction of new and enhanced products, the continuing market adoption of our products, the timing and extent of additional capital expenditures to invest in existing and new office spaces and the number of acquisitions of complementary businesses, including the acquisition of Iridium, products or technologies we pursue, if any. We may be required to seek additional equity or debt financing or we may choose to take advantage of opportunistic capital raising or financing transactions primarily for the purposes noted above. In the event that we require additional financing, we may not be able to raise such financing on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued product innovation, we may not be able to compete successfully, which would harm our business, operations and financial condition. Additionally, we expect our capital and operating expenditures will increase significantly in connection with ongoing activities as we: •increase our investment in marketing, advertising, sales and distribution infrastructure for our existing and future products and services; •develop additional new products and enhancements to existing products, integrate acquisitions and seek new growth opportunities, including additional acquisitions and investments; •obtain, maintain and improve our operational, financial and management performance; •hire additional personnel; •obtain, maintain, expand and protect our and our customer’s intellectual property. Indebtedness As of June 30, 2026, there was $13.4 million outstanding under our 4.250% Convertible Senior Notes due 2029 (the “Convertible Notes”), before unamortized discount and debt issuance costs of $0.2 million. For details regarding our outstanding loan agreements, refer to Note 11 of our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. In connection with the pricing of the Convertible Notes, on February 1, 2024 and February 2, 2024, we entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain financial institutions. These transactions are designed to offset potential dilution from the Convertible Notes and provide a non-dilutive source of liquidity under certain conditions. The Capped Call Transactions have a strike price of $5.1255 per share with a cap price of $8.04 per share, covering approximately 69.3 million shares of common stock. The Capped Call Transactions are scheduled to expire in tranches over a series of dates, beginning on December 1, 2028, and ending on January 30, 2029. If our stock price equals or exceeds the strike price on any given expiration date, we would be entitled to receive payments for the corresponding tranche without issuing additional shares, up to a maximum aggregate payment of approximately $201.9 million across all tranches on the settlement date. However, if the stock price is below the cap price (but is above the strike price) on any expiration date, the payment received for that tranche would be reduced, and the Company may receive less than the maximum potential payment. If the Capped Call Transactions are unwound prior to the maturity dates, the settlement terms would depend on the prevailing market conditions, including our stock price at the time of the unwind, the time remaining until maturity on the date of the unwind, and the expiration schedule of the tranches.
