Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (“SEC”) rules and forms and (2) accumulated and communicated to our management, including our principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. As required by paragraph (b) of Rules 13a-15 and 15d-15 under the Exchange Act, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based upon such evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2025. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act). Our management, including our principal executive officer and our principal financial officer, assessed the effectiveness of our internal control over financial reporting using the criteria set forth by Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). We have excluded from the scope of our assessment of internal control over financial reporting the operations and related assets of GEOST, which we acquired on August 12, 2025. Based on that assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2025. At December 31, 2025 and for the period from the GEOST acquisition on August 12, 2025 through December 31, 2025, total assets and total revenues subject to GEOST’s internal control over financial reporting represented 14% and 2% of consolidated total assets and total revenues, respectively, as of and for the year ended December 31, 2025. Deloitte & Touche LLP, an independent registered public accounting firm, which has audited and reported on the consolidated financial statements contained in this Annual Report on Form 10-K, has issued its report on the effectiveness of the Company’s internal control over financial reporting which is included commencing at page F-1 of this Annual Report on Form 10-K and incorporated herein by reference. Limitations on the Effectiveness of Controls Management recognizes that any controls and procedures, no matter how well-designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Because of these inherent limitations, our disclosure and internal controls may not prevent or detect all instances of fraud, misstatements or other control issues. In addition, projections of any evaluation of the effectiveness of disclosure or internal controls to future periods are subject to risks, including, among others, that controls may become inadequate because of changes in conditions or that the degree of compliance with policies or procedures may deteriorate. Changes in Internal Control over Financial Reporting We assessed, with the participation of our Chief Executive Officer and Chief Financial Officer, any change in our internal control over financial reporting as of the end of the fiscal quarter covered by this Annual Report on Form 10-K. There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2025 covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 56 Table of Contents Item 9B. Other Information Sell to Cover Trading Election On November 24, 2025 , Sir Peter Beck , Chief Executive Officer (the “Participant”), entered into Rule 10b5-1 trading arrangement that is intended to qualify as a “plan providing for eligible sell-to-cover transactions” under Rule 10b5-1(c)(1)(ii)(D)(3) under the Exchange Act.

The sell-to-cover election is effective from March 2, 2026 until December 31, 2027 , unless terminated earlier due to specified events, such as the individual’s death or legal or regulatory restrictions. The number of shares sold under this election will vary based on the tax withholding obligations incurred upon vesting. Item 9C.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2026, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Revenue Recognition – Estimates of revenue and cost at completion for select over-time contracts - Refer to Notes 2 and 3 to the financial statements As further described in Notes 2 and 3 to the financial statements, the Company recognizes revenue as control is transferred to the customer at an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services. For revenue recognized over-time, the Company uses either an input method, based on costs incurred relative to total estimated costs at completion, to estimate the percentage of completion, or an output method, based upon days of service, depending upon the nature of the performance obligation. For revenues measured utilizing an input method, the costs incurred are determined by assessing the physical and technical progress on the performance obligation applied to the standard costs. The estimation of physical and technical progress requires judgment and is subject to many variables including but not limited to actual progress and costs incurred, labor productivity, changes in cost and availability of materials. We analyzed the Company’s contract portfolio to identify contracts that we believe had elevated financial or performance risk. For those contracts identified, the evaluation of one or more of the assumptions used to recognize revenue required extensive audit effort due to the complexity of the contracts and a high degree of auditor judgment. F-2 Table of Contents How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the revenue and cost estimates for these contracts identified included the following, among others: • We tested the effectiveness of controls over the significant assumptions and judgments underlying the estimates of revenues and costs to completion associated with these over-time contracts. • Based on the risk characteristic identified on an individual contract, we evaluated certain revenue and cost assumptions by: ◦ Reading the underlying contract and any amendments or modifications to understand the contractual requirements and performance obligations. ◦ Assessing the timing of recognition of any incentive fees or liquidated damages based on contract terms relative to the progress made towards completion. ◦ Evaluating management’s ability to achieve the estimates of remaining revenue and costs by performing inquiries with the Company’s program and business management regarding their basis of estimates including performance to schedule, program labor and suppliers, reserves related to the program, actual performance to date compared to plan, and any recent correspondence between the Company and the customer on changes, or expected changes in scope or contractual terms. ◦ Evaluating selected changes to the estimates of costs to completion and obtaining supporting documentation on the appropriateness of the timing and amounts of these changes in estimates. ◦ Testing the accuracy and completeness of the information used in developing estimates, as well as the mathematical accuracy of management’s calculation of revenue recognized during the period for the performance obligations. Business Acquisitions – GEOST developed technology intangible asset - Refer to Notes 2 and 4 to the financial statements As further described in Notes 2 and 4 to the financial statements, the Company closed its acquisition of GEOST LLC (“GEOST”) on August 12, 2025. The Company uses the acquisition method of accounting for business combinations and recognizes assets acquired and liabilities assumed measured at their fair values on the date acquired, including developed technology intangible assets of $172,300,000. Determining the fair value of the acquired developed technology intangible assets required management to make significant judgments and estimates including the selection of valuation methodology, estimates of future revenue, costs and cash flows, discount rates and selection of comparable companies. We identified the assumptions related to estimating the amount and timing of expected future revenues to be a critical audit matter given the inherent judgment involved in estimating these amounts. Performing audit procedures to evaluate the reasonableness of these estimates and assumptions required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the expected amount and timing of future revenue used to estimate the fair value of the intangible assets acquired included the following, among others: • We tested the effectiveness of management’s controls over the valuation of intangibles, including management’s controls over the estimates of the amount and timing of expected future revenues. • We assessed the reasonableness of management’s forecasts of future revenues by performing inquiries of appropriate individuals outside of the accounting organization, comparing the projections to historical results, contractual agreements, and third-party industry forecasts. • With the assistance of our fair value specialists, we compared applicable industry forecasted long-term revenue growth rates to management’s projected revenues used within the valuation model. • We evaluated management’s ability to estimate future revenues by comparing actual revenues to estimates assumed in the valuation model. /s/ Deloitte & Touche LLP Los Angeles, California February 26, 2026 We have served as the Company’s auditor since 2018. F-3 Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of Rocket Lab Corporation Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Rocket Lab Corporation and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 26, 2026, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at GEOST LLC, which was acquired on August 12, 2025, and whose financial statements constitute 14% and 2% of consolidated total assets and total revenues, respectively, as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting at GEOST LLC. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP Los Angeles, California February 26, 2026 F-4 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES CONSOLIDATED BALANCE SHEETS AS OF DECEMBER 31, 2025 AND 2024 (in thousands, except share and per share values) December 31, 2025 2024 Assets Current assets: Cash and cash equivalents $ 828,660 $ 271,042 Marketable securities, current 187,917 147,948 Accounts receivable, net 39,001 36,440 Contract assets 61,606 63,108 Inventories 158,407 119,074 Prepaids and other current assets 89,953 55,009 Total current assets 1,365,544 692,621 Non-current assets: Property, plant and equipment, net 319,473 194,838 Intangible assets, net 224,746 58,637 Goodwill 205,750 71,020 Right-of-use assets - operating leases 90,371 53,664 Right-of-use assets - finance leases 13,895 14,396 Marketable securities, non-current 82,247 60,686 Restricted cash 4,885 4,260 Deferred income tax assets, net 1,895 3,010 Other non-current assets 15,672 31,210 Total assets $ 2,324,478 $ 1,184,342 Liabilities and Stockholders’ Equity Current liabilities: Trade payables $ 72,699 $ 53,059 Accrued expenses 19,299 19,460 Employee benefits payable 25,803 20,847 Contract liabilities 195,438 216,160 Current installments of long-term borrowings — 12,045 Other current liabilities 21,237 17,954 Total current liabilities 334,476 339,525 Non-current liabilities: Convertible senior notes, net 152,395 345,392 Long-term borrowings, net, excluding current installments 1,716 44,049 Non-current operating lease liabilities 85,191 51,965 Non-current finance lease liabilities 14,653 14,970 Deferred tax liabilities 1,241 891 Other non-current liabilities 12,952 5,097 Total liabilities 602,624 801,889 COMMITMENTS AND CONTINGENCIES (Note 17) Stockholders’ equity: Preferred stock, $ 0.0001 par value; authorized shares: 100,000,000 ; issued and outstanding shares: 45,951,250 and 0 at December 31, 2025 and December 31, 2024, respectively 5 — Common stock, $ 0.0001 par value; authorized shares: 2,500,000,000 ; issued shares: 589,525,802 and 504,453,785 at December 31, 2025 and December 31, 2024, respectively; outstanding shares 543,574,552 and 504,453,785 at December 31, 2025 and December 31, 2024, respectively 54 50 Treasury stock, at cost; shares: 45,951,250 and 0 at December 31, 2025 and December 31, 2024, respectively — — Additional paid-in capital 2,735,669 1,198,909 Accumulated deficit ( 1,011,910 ) ( 813,701 ) Accumulated other comprehensive loss ( 1,964 ) ( 2,805 ) Total stockholders’ equity 1,721,854 382,453 Total liabilities and stockholders’ equity $ 2,324,478 $ 1,184,342 The accompanying notes are an integral part of these consolidated financial statements.

F-9 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands, except share and per share data) 1. DESCRIPTION OF THE BUSINESS Rocket Lab Corporation (“Rocket Lab” and, together with its consolidated subsidiaries, the “Company,” “we,” “us” or “our”) is an end-to-end space company with an established track record of mission success headquartered in Long Beach, California and is the parent company for several wholly owned operating subsidiaries located in the United States, New Zealand, Canada and Australia. 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. We operate one of the only private orbital launch ranges in the world, located in Mahia, New Zealand, enabling a unique degree of operational flexibility and control of customer launch manifests and mission assurance. While our business has historically been centered on the manufacture of small-class launch vehicles and 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. Merger and Consummation of Holding Company Reorganization On May 8, 2025, Rocket Lab USA, Inc., a Delaware corporation (“Rocket Lab USA”), announced plans to implement a holding company reorganization (the “Reorganization”). On May 23, 2025, Rocket Lab USA implemented the Reorganization pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) dated as of May 23, 2025, among Rocket Lab USA, Rocket Lab and Rocket Lab Merger Sub, Inc., a Delaware corporation and direct, wholly owned subsidiary of Rocket Lab (“Merger Sub”). Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Rocket Lab USA, with Rocket Lab USA continuing as the surviving corporation and a wholly owned subsidiary of Rocket Lab (the “Merger”). Following the Merger, Rocket Lab became the successor issuer to Rocket Lab USA. 2. SIGNIFICANT ACCOUNTING POLICIES Principals of Consolidation and Basis of Presentation The consolidated financial statements are presented in conformity with accounting standards generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Rocket Lab Corporation and its wholly owned subsidiaries after elimination of intercompany accounts and transactions. Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the current period presentation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, our management evaluates estimates and assumptions including those related to revenue recognition, contract costs, loss reserves, valuation of warrants and stock-based compensation and deferred tax valuation allowances, goodwill, intangible assets and contingent consideration. We based our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Actual results could differ from these estimates and assumptions. Operating Cycle For classification of certain current assets and liabilities, we use the duration of the related contract or program as our operating cycle, which is generally longer than one year. Cash and Cash Equivalents The Company considers cash and cash equivalents to be only those investments which are highly liquid, readily convertible to cash and which have a maturity date within ninety days from the date of purchase. The carrying amounts for the Company’s cash equivalents approximate fair value due to their short maturities. Cash equivalents are recorded at fair value and consist primarily of money market funds and certificates of deposit. F-10 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Restricted Cash The Company considers restricted cash to include any cash that is legally restricted as to withdrawal or usage. The Company had $ 4,885 and $ 4,260 as of December 31, 2025 and 2024, respectively. The balance relates to collateral for letters of credit and money market accounts and is presented in restricted cash in the consolidated balance sheets. Marketable Securities Marketable securities consist of investments in corporate debt securities, U.S. Treasury securities, mortgage- and asset-backed securities, commercial paper, certificates of deposit and Yankee bonds mortgage- and asset-backed securities. The Company’s investment policy requires the selection of high-quality issuers. The Company's marketable securities are classified as available-for-sale and are carried at fair value. The Company classifies all available-for-sale marketable securities with maturities greater than one year from the balance sheet date as non-current assets. Interest receivable on marketable securities is presented in prepaids and other current assets on the consolidated balance sheets. Any unrealized holding gains or losses on debt securities, including their tax effect, are reported as components of other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss. Realized gains and losses are included in other income, net in the consolidated statements of operations and comprehensive loss, are determined using the specific identification method for determining the cost of securities sold. Interest and dividend income is recorded when earned and included in interest expense, net on the consolidated statements of operations and comprehensive loss. Premiums and discounts on marketable securities are amortized and accreted, respectively, to earliest call date and maturity, respectively, and included in other income, net on the consolidated statements of operations and comprehensive loss. At each balance sheet date, the Company assesses available-for-sale marketable securities in an unrealized loss position to determine whether it intends to sell or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the available-for-sale security with a fair value below amortized cost is written down to fair value through current period earnings. The Company also reviews its available-for-sale securities in an unrealized loss position to determine whether the unrealized loss is the result of a change in creditworthiness or other factors. If declines in the value of available for-sale securities are determined to be credit-related, a loss is recorded in earnings in the current period. Accounts Receivable, Net Accounts receivables represent amounts billed and currently due from customers. The amounts are stated at their net estimated realizable value. The Company monitors collections and payments from its customers and maintains an allowance for doubtful accounts, which is based upon applying an expected credit loss rate to receivables based on the historical loss rate from similar high-risk customers adjusted for current conditions, including any specific customer collection issues identified, and forecasts of economic conditions. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. The allowance for credit losses as of December 31, 2025 and 2024, and the activity in this account, including the current-period provision for expected credit losses for the years ended December 31, 2025, 2024 and 2023, were not material. Inventories Inventories consist of components and subassemblies, spare parts and consumable goods. Inventories are recorded at actual acquisition costs and adjusted to the lower of cost or estimated net realizable value. Costs include direct material, direct labor, applicable manufacturing and engineering overhead, and other direct costs. Prepaids and Other Current Assets Prepaids and other current assets include goods and services tax, prepaid expenses, deposits, government grant receivables and miscellaneous receivables. Customer Financing The Company records customer financing receivables net of any unamortized discounts and deferred incremental direct costs. Interest income and amortization of any discounts are recorded ratably over the related term of the note to interest income in the consolidated statements of operations and comprehensive loss. F-11 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Interest income recognition is generally suspended for customer financing receivables that are uncollectible. The Company measures and records expected credit losses related to its customer financing in accordance with the current expected credit losses (“CECL”) standard. The CECL standard requires an entity to consider historical loss experience, current conditions, and a reasonable and supportable forecast of the economic environment. Assets Held For Sale The Company generally considers assets to be held for sale when the following criteria are met: (i) management commits to a plan to sell the property, (ii) the property is available for sale immediately, (iii) the property is actively being marketed for sale at a price that is reasonable in relation to its current fair value, (iv) the sale of the property within one year is considered probable and (v) significant changes to the plan to sell are not expected. Property classified as held for sale is no longer depreciated and is reported at the lower of its carrying value or its estimated fair value less estimated costs to sell. Property, Plant and Equipment, Net Property, plant and equipment, net are stated at cost, less accumulated depreciation. The Company has calculated depreciation on a straight-line method. The Company will depreciate over the useful lives as follows: Asset Category Estimated Useful Lives Buildings and improvements 15 to 30 years Machinery, equipment, vehicles and office furniture 2 to 12 years Computer equipment, hardware and software 3 to 5 years Launch site assets 3 to 15 years Leasehold improvements Shorter of remaining lease term or estimated useful life Launch site assets include buildings, machinery and equipment at launch sites. Repair and maintenance costs are expensed as incurred. Assets disposed of or retired are removed from cost and accumulated depreciation accounts and any resulting gain or loss is reflected in the Company’s consolidated statements of operations and comprehensive loss. Business Combination The results of businesses acquired in a business combination are included in our consolidated financial statements from the date of the acquisition. The Company uses the acquisition method of accounting for business combinations and recognizes assets acquired and liabilities assumed measured at their fair values on the date acquired. Goodwill is measured as of the acquisition date as the excess of consideration transferred over the net acquisition date fair value of the assets acquired and the liabilities assumed. The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets and liabilities. Determining the fair value of assets acquired, liabilities assumed and contingent consideration requires us to use significant judgment and estimates, including the selection of valuation methodologies, estimates of future revenue, costs and cash flows, discount rates and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection with determining fair values of assets acquired and liabilities assumed in a business combination. Intangible Assets, Net Intangible assets consist of purchased intangible assets including developed technology, in-process research and development, customer relationships, backlog, trademarks and tradenames, non-compete agreements, capitalized software and capitalized intellectual property and are amortized over their useful lives ranging from one to twenty years using the straight-line method of amortization. The Company evaluates the recoverability of intangible assets periodically by considering events or circumstances that may warrant revised estimates of useful lives or that indicate the asset may be impaired. F-12 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Impairment of Long-Lived Assets Long-lived assets consist of property, plant and equipment and intangible assets with estimable useful lives subject to depreciation and amortization. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of an asset or asset group to be held and used is measured by a comparison of the carrying amount of an asset or asset group to the estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying amount of the asset or asset group exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. There was no impairment of long-lived assets during the years ended December 31, 2025, 2024 and 2023. Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combination. We test goodwill for impairment at least annually during the fourth fiscal quarter, or more frequently if indicators of impairment exist during the fiscal year. Events or circumstances which could trigger an impairment review include a significant adverse change in legal factors or in the business climate, loss of key customers, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business, significant negative industry or economic trends or significant underperformance relative to expected historical or projected future results of operations. When testing goodwill for impairment, the Company first performs a qualitative assessment. If the Company determines it is more likely than not that a reporting unit’s fair value is less than its carrying amount, then a one-step impairment test is required. If the Company determines it is not more likely than not a reporting unit’s fair value is less than its carrying amount, then no further analysis is necessary. To identify whether a potential impairment exists, the Company compares the estimated fair value of the reporting unit with its carrying amount, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill is not considered to be impaired. If, however, the fair value of the reporting unit is less than its carrying amount, then such balance would be recorded as an impairment loss. Any impairment loss is limited to the carrying amount of goodwill allocated to the reporting unit. There was no impairment of goodwill during the years ended December 31, 2025, 2024 and 2023. Fair Value of Financial Instruments We utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. We estimate fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which is categorized in one of the following levels: • Level 1 —Quoted prices in active markets for identical assets or liabilities. • Level 2 —Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The inputs to the determination of fair value are based upon the best information in the circumstances and may require significant management judgment or estimation. The Company considers the carrying values of cash, restricted cash, accounts receivable, accounts payable, and accrued expenses to approximate fair value for these financial instruments due to the short maturities of these instruments. Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis Certain assets and liabilities, including goodwill and intangible assets, are subject to measurement at fair value on a non-recurring basis upon initial acquisition in a business combination or if they are deemed to be impaired as a result of an impairment review. F-13 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Revenue Recognition The Company generates revenue from launch services and space systems. Launch services may be provided as a mission dedicated to a single customer or as a rideshare arrangement with multiple spacecraft from multiple customers. Space systems revenue is comprised of space engineering, program management, spacecraft components, spacecraft manufacturing, space software and mission operations. Revenue is recognized when control of the promised product or service is transferred to our customers at an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services. The Company’s revenue contracts are generally fixed-price contracts or time and materials contracts depending upon the nature of the contract. In fixed-price contracts, to the extent actual costs vary from the cost upon which the price was negotiated, the Company will generate variable levels of profit or could incur a loss. The Company enters into contracts that can include various combinations of products and services, including contracts that contain both launch services and space systems products and services. In general, each launch and space system product or service is capable of being distinct and accounted for as separate performance obligations. Where contracts contain a single performance obligation, the entirety of the transaction price is allocated to this one performance obligation. For contracts with multiple performance obligations, the transaction price is allocated to each performance obligation based on the estimated standalone selling price of the product or service underlying each performance obligation. The standalone selling price represents the amount the Company would sell the product or service to a customer on a standalone basis. The transaction price represents the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised services to its customers. The consideration promised within a contract may include fixed amounts and variable amounts. Variable consideration may consist of final milestone payments, mission success fees or liquidating damages that are earned or penalized if certain contractual milestones are achieved or are not achieved. The Company estimates variable consideration at the most likely amount or expected value, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. The Company recognizes revenue when or as control is transferred to the customer, either over-time or at a point-in-time. Generally, launch services revenue is recognized at a point-in-time when control transfers upon intentional ignition of the launch or where successful delivery milestones are applicable, such as upon delivery of the spacecraft to the specified orbit. However, launch services revenue is recognized over-time when it is determined that there is no alternative use for a launch vehicle, due to significant economic losses to direct the asset for another use or contractual limitations, and the Company has an enforceable right to payment for the services performed to date including a reasonable profit. For launch service revenue recognized over-time, the Company uses an input method, based on costs incurred relative to total estimated costs at completion, to estimate the percentage of completion. The estimation requires judgment and is subject to many variables including but not limited to actual progress and costs incurred, labor productivity, changes in cost and availability of materials. Revenue for space systems is recognized at a point-in-time or over-time depending upon the nature of the contract with customer. For contracts to provide space engineering, program management and mission operations, the Company recognizes revenues over-time as the customer simultaneously receives and consumes the benefits as the Company performs. Similarly, spacecraft manufacturing is recognized over-time when it is determined that there is no alternative use for the spacecraft, due to contractual or practical limitations, and where the Company has an enforceable right to payment for the services performed to date including a reasonable profit. Contracts to provide components for spacecraft that do not qualify for over-time recognition are recognized at a point-in-time when control is transferred. For revenue recognized over-time, the Company uses either an input method, based on costs incurred relative to total estimated costs at completion, to estimate the percentage of completion, or an output method, based upon days of service, depending upon the nature of the performance obligation. For revenues measured utilizing an input method, the costs incurred are determined by assessing the physical and technical progress on the performance obligation applied to the standard costs. Due to the nature of the work performed under spacecraft construction contracts, the estimation of physical and technical progress requires judgment and is subject to many variables including but not limited to actual progress and costs incurred, labor productivity, changes in cost and availability of materials. F-14 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Significant estimates and assumptions are made in estimating contract costs. At the outset of an over-time contract, the Company identifies and monitors risks related to technical, schedule, and cost aspects of the contract, as well as the Company’s ability to earn variable consideration. These risks are assessed throughout the contract period and may result in changes to our estimates of the transaction price or total costs to complete the contract. When such changes occur, we recognize cumulative adjustments to revenue and profit in the period the changes are identified, reflecting the inception-to-date effect of the revised estimates. These adjustments may favorably or unfavorably impact the Company’s gross margin. If our actual costs exceed our estimates, our margins and profits are reduced and we could incur a provision for contract loss. A provision for contract loss is when estimates of total costs to be incurred on a contract exceed total estimates of the transaction price. When this occurs, a provision for the entire loss is determined at the contract level and is recorded in the period in which the loss is evident. Contracts for space software provide the customer with a right to use the software as it exists when made available to the customer. Customers may purchase perpetual entity-wide licenses or mission-based licenses, which provide customers with the same functionality and differ primarily in the number of spacecraft into which the software may be integrated. Revenue from space software is recognized upfront at the point-in-time when the software is made available to the customer. Revenue from software maintenance is recognized ratably over the maintenance period. Due to their nature, time and materials contracts contain variable consideration; however, in general, the Company’s performance obligations under time and materials contracts qualify for the “right to invoice” practical expedient. Under this practical expedient, the Company recognizes revenue, over time, in the amount to which the Company has a right to invoice. In addition, the Company is not required to estimate such variable consideration upon inception of the contract and reassess the estimate each reporting period. The Company determined that this method best represents the transfer of services as, upon billing, the Company has a right to consideration from a customer in an amount that directly corresponds with the value to the customer of the Company’s performance completed to date. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. Timing may differ between the satisfaction of performance obligations and the invoicing and collection of amounts related to our contracts with customers. Contract assets include unbilled amounts under contracts when revenue recognized exceeds the amount billed to the customer. Contract assets are transferred to accounts receivable when the right to invoice becomes unconditional and the invoice is issued. Contract assets are classified as current assets consistent with our operating cycle. These contract assets are not considered a significant financing component of the Company’s contracts as the payment terms are intended to protect the customer in the event the Company does not perform on its obligations under the contract. Contract liabilities primarily consists of customer billings in advance of revenues being recognized. Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs within a one-year period or are used to ensure the customer meets contractual requirements. Cost of Revenues Cost of revenues, for both products and services, 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. Research and Development, net Research and development, net consists of labor, prototype, professional services, materials, facilities and depreciation expense related to the development of our Neutron launch vehicle, space system platforms and components. These costs are based on a cost model for research and development relating to internal product development programs not associated with customer contractual arrangements. These costs are presented net of government grants on the consolidated statements of operations and comprehensive loss. These costs are expensed as incurred until the program transitions from development to commercial production, at which point costs may be capitalized as inventory. Selling, General and Administrative Selling, general and administrative expenses consist of indirect costs, including management and executive compensation, corporate costs related to finance, accounting, human resources, information technology, legal, administrative, safety, professional services, rent, advertising costs and other general expenses. F-15 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Government Assistance The Company receives government assistance from various domestic and foreign governments in the form of cash grants or refundable tax credits. These arrangements incentivize us to continue growing our capital investments and research and development activities. Government incentives generally contain conditions that must be met in order for the assistance to be earned. We recognize the incentives when there is reasonable assurance that we will comply with all conditions specified in the incentive arrangement and the incentive will be received. The Company records incentives related to operating activities as a reduction to expense in the same line item on the consolidated statements of operations and comprehensive loss as the expenditure for which the grant is intended to compensate. The Company records capital expenditure related incentives as an offset to the associated property, plant and equipment, net within our consolidated balance sheets and recognize a reduction to depreciation expense over the useful life of the corresponding acquired asset. The Company has applied for tax credits related to a research and development tax incentive program with the New Zealand government. This tax incentive will reimburse up to 15 % of the Company’s qualifying research and development costs incurred. The Company has various research government assistance awards which includes the Air Force Research Laboratory and the U.S. Space Force’s Space Systems Command. The Company applied for the employee retention credit under the CARES Act during the year ended December 31, 2023. On November 22, 2024, the Company entered into a direct funding agreement with the U.S. Department of Commerce to receive direct funding for the procurement, installation and qualification of new manufacturing equipment and will also receive funding by claiming the refundable Advanced Manufacturing Investment Credit under the United States CHIPS and Science Act of 2022. The Company recorded $ 2,130 of government assistance as a reduction of cost of revenues during the year ended December 31, 2023.The Company recorded $ 18,976 , $ 12,983 and $ 27,385 of government assistance as a reduction of research and development, net during the years ended December 31, 2025, 2024 and 2023, respectively. The Company recorded $ 0 , $ 250 and $ 1,080 of government assistance as a reduction of selling, general and administrative during the years ended December 31, 2025, 2024 and 2023, respectively. During the years ended December 31, 2025 and 2024, the Company recorded capital expenditure incentive of $ 1,536 and $ 2,186 as an offset to property, plant and equipment, net, respectively . As of December 31, 2025 and 2024, prepaids and other current assets includes government assistance receivables of $ 15,629 and $ 7,783 , respectively. As of December 31, 2025 and 2024, other non-current assets includes government assistance receivables of $ 0 and $ 5,863 , respectively. Stock-Based Compensation The Company’s stock compensation plan is classified as an equity plan which permits stock awards in the form of employee stock options and restricted stock awards. For awards that vest solely based on continued service, the fair value of an award is recognized as an expense over the requisite service period on a straight-line basis. The fair value of stock options under the Company’s employee equity incentive plan are estimated as of the grant date using the Black-Scholes option valuation model, which is affected by the fair value per share of common stock, the expected share price volatility of its common shares over the expected term, expected term, risk-free interest rate and expected dividend yield, which are estimated as follows: • Fair value per share of common stock . The fair value of common stock is based on the market price of our common stock underlying the awards on the grant date. • Expected volatility . The volatility is based on the weighted average historical volatilities of the Company and a pool of public companies that are comparable to the Company. Expected volatility represents the estimated volatility of the shares over the expected life of the options. • Expected term . The Company determines the expected term of the awards using the simplified method. The simplified method estimates the expected term based on the average of the vesting period and contractual term of the stock option. • Risk-free interest rate . The risk-free interest rate for periods within the expected life of the option is derived from the U.S. treasury interest rates in effect at the date of grant. F-16 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) • Estimated dividend yield . The Company uses an expected dividend yield of zero since no dividends are expected to be paid. The fair value of restricted stock units granted under the Company’s employee equity incentive plans are estimated as of the grant date in an amount equal to the estimated fair value per share of the Company’s common stock. Forfeitures are recognized as incurred. Unless otherwise approved, options must be exercised while the individual is an employee or within 90-days of termination when applicable. The expiration date of newly issued options is ten years after grant date unless earlier terminated as provided for in the Rocket Lab 2021 Stock Option and Incentive Plan. The assumptions used in calculating the fair value of stock-based awards represent our best estimates, however, these estimates involve inherent uncertainties and the application of judgment. As a result, if factors change or we use different assumptions, stock-based compensation expense could be materially different in the future. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized by applying the statutory tax rates in effect in the years in which the differences between the financial reporting and tax filing bases of existing assets and liabilities are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company utilizes a two-step approach to recognizing and measuring uncertain income tax positions (tax contingencies). The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company makes estimates, assumptions and judgments to determine its provision for income taxes and also for deferred tax assets and liabilities and any valuation allowances recorded against deferred tax assets. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting its consolidated financial position and results of operations. Segment Information Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined that it operates in two reportable segments: launch services and space systems. Foreign Currencies The functional currency of certain of the Company’s wholly owned subsidiaries is the currency of the primary economic environment in which they operate. Assets and liabilities denominated in currencies other than the functional currency are remeasured at the exchange rate in effect on the balance sheet date, with exchange differences or remeasurement included in other income, net on the consolidated statement of operations and comprehensive loss. Revenue and expenses are translated at average rates of exchange prevailing during the respective period. Translation adjustments resulting from this process are recorded as a component of accumulated other comprehensive income (loss) in the consolidated statements of changes in stockholders’ equity. Leases The Company leases certain property, vehicles and equipment. At contract inception, the Company determines if a contract contains a lease and whether the lease should be classified as an operating or financing lease. F-17 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Right of use (“ROU”) assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, it uses the incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also includes any lease prepayments made and excludes lease incentives. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. Finance leases result in the recognition of depreciation expense, which is recognized on a straight-line basis over the expected life of the leased asset, and interest expense, which is recognized following an effective interest rate method. The Company excludes short-term leases (term of 12 months or less) from the balance sheet presentation and accounts for non-lease and lease components in a contract as a single lease component for certain asset classes. Convertible Senior Notes The Company accounts for convertible senior notes under Accounting Standards Codification (“ASC”) ASC 470-20 - Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity's Own Equity (“ASU 2020-06”). The Company records the convertible senior notes as a long-term liability at face value net of debt issuance costs. If certain conditions to the convertibility of the convertible senior notes are satisfied, or the convertible senior notes become due within one year, then the Company may be required under applicable accounting standards to reclassify the carrying value of the convertible senior notes as a current, rather than a long-term liability. If it is determined that the Company cannot be required to settle the Notes in cash and has the intent and ability to settle in common stock, the Notes are classified as non-current liabilities on the Company’s consolidated balance sheet. Debt issuance costs related to the convertible senior notes were capitalized and recorded as a contra-liability and are presented net against the convertible senior notes balance on the consolidated balance sheets. Debt issuance costs consist of underwriting, legal and other direct costs related to the issuance of the convertible senior notes and are amortized to interest expense over the term of the convertible senior notes using the effective interest method. Capped Call Transactions Capped call transactions cover the aggregate number of shares of the Company’s common stock that will initially underlie the convertible senior notes. The Company determined that the freestanding capped call option contracts qualify as equity under the accounting guidance on indexation and equity classification, and recognized the contract by recording an entry to Additional paid-in capital in stockholders’ equity in the consolidated balance sheets and not remeasured. Warrants The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity, and ASC 815, Derivative and Hedging. For warrants that meet all the criteria for equity classification, the warrants are recorded as a component of additional paid-in capital at the time of issuance. Warrants classified as liabilities are recognized at fair value and remeasured at fair value at each reporting period with any change in fair value recognized in the consolidated statements of operations and comprehensive loss. Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which focuses on the rate reconciliation and income taxes paid. ASU 2023-09 requires a public business entity (“PBE”) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, further broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign jurisdictions, and further by individual jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-09 prospectively for the period ending December 31, 2025, and it affects only our disclosures and does not impact our results of operations or financial condition. F-18 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (DISE) (“ASU 2024-03”), which requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The amendments in ASU 2024-03 will be applied prospectively with the option for retrospective application and early adoption is permitted. The Company is assessing the potential impact of adopting ASU 2024-03 on its financial statements. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”), which modernizes the accounting for internal-use software. ASU 2025-06 removes all references to software development stages and requires capitalization of software costs when management has committed to the software project and it is probable the software will be completed and perform its intended use. ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027, with early adoption permitted and can be applied on either a prospective, modified, or retrospective basis. The Company is assessing the potential impact of adopting ASU 2025-06 on its financial statements. In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities (“ASU 2025-10”). ASU 2025-10 establishes guidance for the recognition, measurement, and presentation of government grants received by business entities. Under the new standard, a government grant is recognized only when it is probable that (i) the entity will satisfy the grant’s conditions and (ii) the grant will be received. If those conditions are met, the grant is classified either as a grant related to income or as a grant related to an asset, and the classification determines the appropriate accounting treatment. ASU No. 2025-10 retains the existing disclosure requirements in Topic 832, Government Assistance. For public business entities, the amendments are effective for annual reporting periods beginning after December 15, 2028, and for interim reporting periods within those annual reporting periods, with early adoption permitted. Entities may adopt the amendments using a modified-prospective, modified-retrospective, or full-retrospective approach for all government grants. We are currently evaluating the impact of the ASU on our disclosures and financial statements, including the approach and the timing of adoption. 3. REVENUES The Company disaggregates revenue by reportable segment and revenue recognition pattern, as it believes these categories best depicts how the nature, timing and uncertainty of revenue and cash flows are affected by economic factors. The following tables provide information about disaggregated revenue and a reconciliation of the disaggregated revenue during the years ended December 31, 2025, 2024 and 2023: Year Ended December 31, 2025 Launch Services Space Systems Total Revenues by recognition model Point-in-time $ 159,308 $ 107,432 $ 266,740 Over-time 39,734 295,325 335,059 Total revenue by recognition model $ 199,042 $ 402,757 $ 601,799 Year Ended December 31, 2024 Launch Services Space Systems Total Revenues by recognition model Point-in-time $ 125,338 $ 74,636 $ 199,974 Over-time 38 236,202 236,240 Total revenue by recognition model $ 125,376 $ 310,838 $ 436,214 F-19 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Year Ended December 31, 2023 Launch Services Space Systems Total Revenues by recognition model Point-in-time $ 71,131 $ 46,704 $ 117,835 Over-time 763 125,994 126,757 Total revenue by recognition model $ 71,894 $ 172,698 $ 244,592 The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, unbilled receivables (presented within contract assets) and customer advances and deposits (presented within contract liabilities) on the consolidated balance sheets, where applicable. Amounts are generally billed as work progresses in accordance with agreed-upon milestones. These individual contract assets and liabilities are reported in a net position on a contract-by-contract basis on the consolidated balance sheets at the end of each reporting period. The following table presents the balances related to enforceable contracts as of December 31, 2025 and 2024: December 31, 2025 2024 Contract balances Accounts receivable, net $ 39,001 $ 36,440 Contract assets 61,606 63,108 Contract liabilities ( 195,438 ) ( 216,160 ) Changes in contract liabilities were as follows: 2025 2024 2023 Contract liabilities, beginning of year $ 216,160 $ 139,338 $ 108,344 Contract liabilities assumed at acquisition 842 — — Customer advances received or billed, net 160,887 176,763 137,158 Recognition of unearned revenue ( 182,451 ) ( 99,941 ) ( 106,164 ) Contract liabilities, end of year $ 195,438 $ 216,160 $ 139,338 The revenue recognized from the contract liabilities consisted of the Company satisfying performance obligations during the normal course of business. The amount of revenue recognized in the aggregate from changes in the transaction price or estimated costs to complete associated with performance obligations satisfied in prior periods during the year ended December 31, 2025, included a $ 15,055 downward adjustment to revenue and a $ 7,140 upward adjustment to revenue, resulting in a net downward adjustment of $ 7,915 , respectively. Included in the downward adjustment for the year ended December 31, 2025, the Company recorded a downward adjustment to revenue of $ 12,818 related to an individual contract. This cumulative catch-up adjustment resulted from changes in the estimated costs to complete the contract. For the years ended December 31, 2024 and 2023, the impact was not material. In February 2022, the Company entered into a procurement agreement with MDA Corporation to design and manufacture of 17 spacecraft buses (the “MDA Contract”). The Company has determined that the projected delivery dates for certain deliverables will be later than the dates originally set out under the MDA Contract. This delay is the result of a number of factors, including delays that have arisen in the Company’s supply chain. Under the terms of the MDA Contract, the customer is potentially entitled to claim liquidated damages as a result of this delivery delay. The Company is similarly entitled to claim liquidated damages against certain suppliers that have contributed to these delays. At this time, it is not possible to determine with certainty the net amount, if any, of actual liquidated damages that could ultimately be incurred. F-20 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Backlog The Company’s backlog represents the estimated transaction prices on performance obligations to the Company’s customers for which work remains to be performed. The amount of backlog increases with new contracts or additions to existing contracts and decreases as revenue is recognized on existing contracts. Contracts are included in the amount of backlog when an enforceable agreement has been reached. Remaining backlog totaled $ 1,847,322 as of December 31, 2025, of which approximately 37 % is expected to be recognized within 12 months, with the remaining 63 % to be recognized beyond 12 months. Customer Financing In connection with the signing of three separate multi-launch agreements with commercial customers, the Company entered into subordinated loan and security agreements and a loan and security agreement. The commercial customers may choose to have certain milestone payments financed under the terms of the subordinated loan and security agreements. The receivables will bear no interest until the initial launch dates passes, after which interest will accrue at a fixed rate of 9.5 %, 10.8 % or 12.6 %, based on the agreement. Principal and interest payments will be made over 12 quarterly payments from the launch date. On July 11, 2025, the Company received a full payoff of $ 7,489 and terminated the subordinated loan and security agreement with one of the commercial customers. As of December 31, 2025 and 2024, the Company had $ 6,750 and $ 4,200 customer financing in prepaids and other currents assets, respectively and $ 16,138 and $ 15,567 customer financing receivable in other non-current assets on the consolidated balance sheets, respectively. Customer financing interest income for the years ended December 31, 2025, 2024 and 2023 was $ 1,730 , $ 1,213 and $ 371 , respectively. 4. BUSINESS COMBINATIONS AND ASSET ACQUISITIONS GEOST On August 12, 2025, the Company closed the acquisition of GEOST LLC ( “GEOST”) pursuant to a Stock Purchase Agreement (the “GEOST Purchase Agreement”), by and among Rocket Lab USA, LightRidge Solutions Holdings LP (“LightRidge Solutions”), and LightRidge Interco Solutions Holdings, Inc. (“LightRidge Interco”), which provided for, among other things, the Company’s purchase and acquisition of all of the issued and outstanding shares of common stock of LightRidge Interco, the owner of GEOST. Pursuant to the terms of the GEOST Purchase Agreement, all of the issued and outstanding shares of LightRidge Interco were purchased in exchange for aggregate consideration of $ 275,000 , consisting of approximately $ 125,000 in cash and 3,057,588 shares of common stock, subject in each case to customary adjustments at closing, including for cash, working capital, transaction expenses and indebtedness (the “Transaction”).

(2) The contingent consideration, to be paid in cash, was classified as a liability and included in other non-current liabilities on the Company’s consolidated balance sheets. To estimate the fair value of the contingent consideration liability, management valued the earn-out based on the likelihood of reaching certain revenue targets. At the acquisition date, the fair value of the contingent consideration payable was measured based on a Monte Carlo simulation utilizing projections about future performance. Significant inputs at acquisition include revenue volatility of 29 %, discount rate of 10 % and projected financial information. F-22 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) The following is a summary of preliminary identifiable intangible assets acquired and the related expected lives for the finite-lived intangible assets: Type Estimated Life in Years Fair Value Developed technology 10 $ 172,300 Backlog 5 11,000 Total identifiable intangible assets acquired $ 183,300 Goodwill of $ 134,730 was recorded for the GEOST acquisition, representing the excess of the purchase price over the fair value of the identifiable net assets. The goodwill has been allocated to the space systems operating segment, reflecting the strategic operations of this operating segment. Goodwill recognized primarily represents the future revenue and earnings potential and certain other assets which were acquired, but that do not meet the recognition criteria, such as assembled workforce. The majority of goodwill is not expected to be deductible for income tax purposes. The Company’s consolidated statements of operations for the year ended December 31, 2025 includes revenues and operating loss of $ 11,946 and $ 8,314 , respectively, related to the GEOST acquisition. Measurement Period During the measurement period, the Company will continue to obtain information to assist in determining the fair value of net assets acquired, which may differ materially from these preliminary estimates. Specifically, the Company is evaluating outstanding matters, including but not limited to, legal contingencies, other receivables, tax-related items and other assets. Measurement period adjustments, if applicable, will be applied in the reporting period in which the adjustment amounts are determined. Measurement period changes made in the fourth quarter of 2025 for the GEOST acquisition did not have a material impact.

Declines in value are largely attributable to current global economic conditions. The securities continue to make timely principal and interest payments, and the fair values are expected to recover as they approach maturity. The Company does not intend to sell the securities, and it is not more likely than not that the Company will be required to sell the securities, before the respective recoveries of their amortized cost bases, which may be maturity. As of December 31, 2025, the Company had not recognized an allowance for credit losses on any marketable securities in an unrealized loss position.

There were no transfers between fair value measurement levels during the years ended December 31, 2025 and 2024. Contingent Consideration The Company recorded a contingent consideration liability related to potential earnout payments based on revenue targets pursuant to the GEOST Purchase Agreement. The estimated fair value of the contingent consideration is recorded using significant unobservable measures and other fair value inputs and is therefore classified as a Level 3 financial instrument. The following table presents contingent consideration obligations measured on a recurring basis using Level 3 inputs for the year ended December 31, 2025: December 31, 2024 $ — Acquisition-related contingent consideration 18,258 Fair value adjustment ( 10,624 ) December 31, 2025 $ 7,634 During the year ended December 31, 2025, the fair value of contingent consideration for the earn-out in connection with the acquisition of GEOST decreased, primarily due to a push out of forecasted revenues, resulting from the delay in contract awards caused by the government shutdown. Convertible Senior Notes The Company measures the fair value of its convertible senior notes on a quarterly basis for disclosure purposes. The Company considers the fair value of its convertible senior notes as of December 31, 2025 to be a Level 2 measurement due to limited trading activity of the convertible senior notes. As of December 31, 2025, the net carrying amount of the convertible senior notes was $ 152,395 , with unamortized discount and debt issuance costs of $ 3,259 . As of December 31, 2025, the total estimated fair value (Level 2) of the convertible senior notes was $ 2,185,440 . The fair value was determined based on the closing trading price of the convertible senior notes as of the last day of trading for the period.

ASSETS HELD FOR SALE In the first quarter of 2023, the Company updated its Electron recovery strategy by completing a marine recovery, which we believe will be a more effective and financially viable type of recovery. As a result, the Company has ceased mid-air rocket booster recovery and began the sale process of two helicopters. As of March 31, 2023, the Company’s two helicopters met the held for sale criteria and the Company ceased depreciating these assets. On June 6, 2024, the Company sold one of the Company’s held for sale helicopters to a purchaser unaffiliated with the Company, for $ 12,030 before closing costs and holdbacks.

LOAN AGREEMENTS Indenture and Notes On February 6, 2024, the Company issued $ 355,000 aggregate principal amount of its 4.250 % Convertible Senior Notes due 2029 (the “Notes”). The Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of February 6, 2024, between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s future indebtedness that is expressly subordinated to the Notes in right of payment; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, including borrowings under its equipment financing agreement, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries. F-29 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) The Notes accrue interest at a rate of 4.250 % per annum, payable semi-annually in arrears on February 1 and August 1 of each year, beginning on August 1, 2024. The Notes mature on February 1, 2029, unless earlier converted, redeemed or repurchased. Before November 1, 2028, noteholders have the right to convert their Notes only during the following circumstances: (i) during any calendar quarter (and only during such calendar quarter) if the last reported sale price of the Company’s common stock exceeds 130 % of the conversion price for each of at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter, (ii) during the five consecutive business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1 principal amount of Notes for each trading day of the measurement period was less than 98 % of the product of the last reported sale price of the Company’s common stock and the applicable conversion rate on each such trading day, (iii) upon the occurrence of certain corporate events or distributions specified in the Indenture or (iv) if the Company calls such Notes for redemption. From and after November 1, 2028, noteholders may convert their Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. The initial conversion rate is 195.1029 shares of common stock per $1 principal amount of Notes, which represents an initial conversion price of approximately $ 5.13 per share of common stock. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. As of December 31, 2025, the holder of the Notes have the right to convert between January 1, 2026 and March 31, 2026 because the Company’s common stock price exceeded the applicable conversion price by 130 % for the specified period of time during the quarter ended December 31, 2025. When a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. During the year ended December 31, 2025, the Company received conversion notices for $ 199,346 aggregate principal amount of Notes. These conversions resulted in the issuance of 38,892,968 shares of common stock in accordance with the terms of the Indenture governing the Notes. As of December 31, 2025, the Company cannot be required to settle the Notes in cash and has the intent and ability to settle in common stock, therefore, the Notes were classified as non-current liabilities on the Company’s consolidated balance sheet. As of December 31, 2025, there was $ 155,654 outstanding under the Notes, before unamortized discount and debt issuance costs of $ 3,259 . As of December 31, 2025, the effective interest rate under the Notes was 5.0 %. Capped Call Transactions In connection with the pricing of the Notes, on February 1, 2024 and February 2, 2024, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain financial institutions. Collectively, the Capped Call Transactions cover, subject to customary adjustments, the number of shares of common stock initially underlying the Notes. The cost of the Capped Call Transactions was $ 43,168 . The Capped Call Transactions are expected generally to reduce or offset the potential dilution to the Company’s common stock upon exercise of the Notes and/or the Company’s election to offset the cash payments the Company is required to make in excess of the principal amount of the Notes upon conversion of the Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the Capped Call Transactions (which initially corresponds to the initial conversion price of the Notes and is subject to certain adjustments under the terms of the Capped Call Transactions), with such reduction and/or offset subject to a cap based on the cap price of the Capped Call Transactions. The Capped Call Transactions have an initial cap price of $ 8.04 per share of the Company’s common stock, which represents a premium of 100 % over the last reported sale price of the Company's common stock on February 1, 2024. The Capped Call Transactions do not meet the criteria for separate accounting as a derivative as they are indexed to the Company’s stock. The premiums paid for the Capped Call Transactions have been included as a net reduction to additional paid-in capital within shareholders’ equity. F-30 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) Trinity Master Equipment Financing Agreement On December 29, 2023 (the “Effective Date”), the Company and certain of its subsidiaries (the “Subsidiaries”, together with the Company, the “Borrowers”), entered into a Master Equipment Financing Agreement (the “Trinity Loan Agreement”) with Trinity Capital, Inc., a Maryland corporation (the “Lender”) to provide financing for certain equipment and other property (the “Equipment”). The Trinity Loan Agreement provides that the Lender shall provide equipment financing in the aggregate of up to $ 120,000 (the “Conditional Commitment”), with advances (“Draws”) to be made as follows: (i) $ 70,000 on the Effective Date (the “Effective Date Draw”); and (ii) $ 40,000 to be drawn on the Effective Date (the “Blanket Lien Draw”), with each of the Effective Date Draw and Blanket Lien Draw payable over sixty ( 60 ) months beginning January 2024, with the final payments due in January 2029.

In connection with the Loan Agreement, the Company issued warrants to Lender to acquire 728,835 shares of the Company’s common stock at an exercise price of $ 4.87 per share (see Note 13). The proceeds from the Loan Agreement were allocated to the loan and warrants based on the relative fair value at inception, resulting in a reduction to the loan amount and amortized to interest expense over the term of the loan. On February 8, 2024, the Company paid off all obligations under the Blanket Lien Draw in the amount of $ 38,778 , which includes principal, unpaid interest and legal fees, resulting in a loss on extinguishment of debt of $ 1,330 for the year ended December 31, 2024, included in other income, net in the consolidated statements of operations and comprehensive loss. On March 20, 2025, the Company made a draw of $ 25,000 under the Trinity Loan Agreement (the “March 2025 Draw”). This March 2025 Draw has a term of sixty ( 60 ) months and a rate factor of 0.022266 . On December 15, 2025, the Company paid off all obligations under the Trinity Loan Agreement in the amount of $ 69,120 , which includes principal, prepayment fees, end of term and other fees and unpaid interest, resulting in a loss on extinguishment of debt of $ 5,926 for the year ended December 31, 2025. As a result, the Trinity Loan Agreement was terminated. Hercules Capital Secured Term Loan On June 10, 2021, the Company entered into a $ 100,000 secured term loan agreement with Hercules Capital, Inc. (the “Hercules Capital Secured Term Loan”) and borrowed the full amount under the secured term loan agreement. The term loan had a maturity date of June 1, 2024 and was secured by substantially all of the assets of the Company. Payments due for the term loan were interest-only until the maturity date with interest payable monthly in arrears. The outstanding principal bore (i) cash interest at the greater of (a) 8.15 % or (b) 8.15 % plus the prime rate minus 3.25 % and (ii) payment-in-kind interest of 1.25 % which was accrued and added to the outstanding principal balance. Prepayment of the outstanding principal was permitted under the loan agreement and subject to certain prepayment fees. On June 10, 2021, in connection with the secured term loan, the Company paid an initial facility charge of $ 1,000 . On December 29, 2023, the Company was required to pay an end of term charge of $ 3,250 upon repayment of the loan. On December 29, 2023, a portion of the proceeds from the Effective Date Draw and the Blanket Lien Draw were used to pay off all obligations owing pursuant to the Hercules Capital Secured Term Loan, resulting in a loss on extinguishment of debt of $ 1,732 for the year ended December 31, 2023.

STOCKHOLDERS’ EQUITY Preferred Stock The Company entered into an exchange agreement dated December 3, 2024 with The Equatorial Trust (the “Trust”), a family trust established by Sir Peter Beck (“Sir Peter”), the Company’s Founder, President, Chief Executive Officer and Chairman, to exchange (the “Preferred Stock Exchange”) 50,951,250 shares of the Company’s common stock into 50,951,250 shares of the Company’s Series A Convertible Participating Preferred Stock, $ 0.0001 par value per share (the “Preferred Stock”). On January 7, 2025, the Preferred Stock Exchange was consummated (the “Closing”) and the Company filed the Certificate of Designation for the Preferred Stock (the “Certificate of Designation”) with the Secretary of State of the State of Delaware, which became effective upon filing. At the Closing, the Company issued 50,951,250 shares of Preferred Stock to the Trust. On June 17, 2025, the Trust converted 5,000,000 shares of the Preferred Stock to common stock on a one -for-one basis in accordance with the Certificate of Designation. The common stock exchanged in the Preferred Stock Exchange were reacquired at no cost and held in treasury stock until they are reissued or retired. The fair value of the Preferred Stock issued was determined to be equal to the fair value of the common stock exchanged. The Preferred Stock has the rights and restrictions set forth in a Certificate of Designation. Each share of Preferred Stock is convertible at any time at the option of the holder of the Preferred Stock (a “Holder”) into a number of shares of Common Stock at the then-applicable conversion rate (the “Conversion Rate”). In addition, each share of Preferred Stock automatically converts into a number of shares of Common Stock at the Conversion Rate upon the earliest to occur of (a) a transfer of such share (other than to a Permitted Transferee), (b) the first date on which Sir Peter no longer serves as (i) the Chief Executive Officer of the Company or (ii) such other executive officer position of the Company as approved by the Board, (c) Sir Peter’s death or permanent disability, or (d) the first date on which the outstanding shares of Preferred Stock no longer represent a minimum beneficial ownership by Sir Peter of five percent. A “Permitted Transferee” is defined in the Certificate of Designation and includes Sir Peter and his controlled affiliates. The Preferred Stock is not redeemable by the Company at any time. The Certificate of Designation also provides that for so long as any shares of Preferred Stock are outstanding, the Holders, voting exclusively and as a separate class, will be entitled to designate and elect at least one individual to serve on the Board as a director (a “Preferred Stock Director”). In the event the Board increases its size to more than ten members, the Holders are entitled to designate and elect, voting exclusively and as a separate class, one or more additional Preferred Stock Directors in order to maintain the right to elect ten percent of the total number of authorized directorships, rounded up to the nearest whole number. The right to designate a Preferred Stock Director is nontransferable. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, after the satisfaction in full of the Company’s debts and the payment of any liquidation preference ranking senior to the Preferred Stock, Holders are entitled to receive an amount equal to $ 0.0001 per share of Preferred Stock. Following the payment of the full amount of the liquidation preference in respect of all outstanding shares of Preferred Stock, Holders participate pari passu with the holders of the Common Stock (on an as-if-converted-to-Common-Stock basis) in the net assets of the Company. The Preferred Stock is not entitled to any scheduled dividend payments. Holders will be entitled to receive dividends on shares of Preferred Stock equal (on an as-if-converted-to-common-stock basis) to, and in the same form as dividends actually paid on, all or substantially all of the shares of common stock when, as and if such dividends (other than dividends in the form of common stock) are paid on shares of the common stock, subject to certain exceptions specified in the Certificate of Designation. The Preferred Stock will have the right to vote on all matters submitted for a vote of the holders of the common stock, voting together as a single class with the common stock. Each Holder will be entitled to cast a number of votes per share equal to the number of shares of common stock into which a share of Preferred Stock is convertible. In addition, the Company may not, without the affirmative vote of the Holders of a majority of the then outstanding shares of Preferred Stock: (a) alter, amend or repeal any provision of the Company’s certificate of incorporation if it would alter or change the powers, preferences or special rights of the Preferred Stock so as to affect them adversely, (b) alter or amend the Certificate of Designation, or (c) increase the authorized number of shares of Preferred Stock or authorize the issuance of additional shares of Preferred Stock.

Equity Classified Common Stock Warrants The Company has issued equity classified warrants which are settled through issuance of common stock. Upon settlement, the warrants are recognized as additional paid-in capital, a component of equity in the consolidated balance sheets. In connection with the Loan Agreement, the Company issued a warrant (“Warrant”), dated December 29, 2023, to purchase up to 728,835 shares of the Company’s common stock, at an exercise price of $ 4.87 per share, payable in cash or on a cashless basis according to the formula set forth in the Warrant. The exercise price of the Warrant and the number of shares issuable upon exercise of the Warrant were subject to adjustments for stock splits, combinations, stock dividends or similar events. On November 14, 2024, all 728,835 common stock warrants were exercised on a cashless basis, which resulted in the holder of the warrants receiving 540,336 shares of common stock. The following assumptions were used in the Black-Sholes pricing model calculation for the Warrant issued: Share price $ 5.53 Strike price $ 4.87 Expected volatility 82.0 % Risk-free interest rate 3.85 % Expected life (years) 4.0 Dividend rate None F-33 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) 14. STOCK-BASED COMPENSATION Equity Incentive Plans The Company has a single active equity incentive plan, the Rocket Lab 2021 Stock Option and Incentive Plan (the “2021 Plan”), with the objective of attracting and retaining available employees and directors by providing stock-based and other performance-based compensation. The Rocket Lab 2013 Stock Option and Grant Plan (the “2013 Plan”) was terminated, but outstanding awards granted thereunder remain governed by it. The 2021 Plan provides for the grant of equity awards to officers, employees, directors and other key employees as well as service providers which include incentive stock options, non-qualified stock options, restricted stock awards, unrestricted stock awards, restricted stock units or any combination of the foregoing any of which may be performance based, as determined by the Company’s Compensation Committee. An aggregate of 59,875,000 shares were initially reserved for the issuance of awards under the 2021 Plan. The number of shares reserved for issuance under the 2021 Plan automatically increases each January 1, beginning on January 1, 2022, by 5 % of the outstanding number of shares of common stock on the immediately preceding December 31, or such lesser amount as determined by the plan administrator. The Company was authorized to issue and has registered with the Securities and Exchange Commission 104,631,817 shares of common stock as equity awards to participants under the 2021 Plan as of December 31, 2025.

In addition, the number of shares reserved for issuance will ultimately increase on January 1 of each year from 2022 to 2031 by the lesser of (i) 9,980,000 shares of common stock, (ii) 1 % of the number of shares of common stock outstanding as of the close of business on the immediately preceding December 31 or (iii) the number of common stock shares as determined by the Company’s board of directors. The purpose of the 2021 ESPP is to enable eligible employees to use payroll deductions to purchase shares of common stock and thereby acquire an interest in the Company. Eligible employees are offered shares through a 12-month offering period, which consists of two consecutive 6-month purchase periods. Employees may purchase a limited amount of shares of our stock at a discount of up to 15 % of the lesser of the fair market value at the beginning of the offering period or the end of each 6-month purchase period. During the years ended December 31, 2025, 2024 and 2023, 602,669 , 1,473,720 and 1,369,604 shares of common stock were issued under the 2021 ESPP.

LEASES The Company has operating and finance leases for properties, vehicles and equipment. The Company’s operating and finance leases have remaining lease terms of less than one year to twenty-five years , some of which include options to extend the lease term, and some of which include options to terminate the lease prior to the end of the agreed upon lease term. For purposes of calculating lease liabilities, lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options.

COMMITMENTS AND CONTINGENCIES Litigation and Claims The Company is, and from time to time may be, a party to claims and legal proceedings generally incidental to its business that are principally covered under contracts with its customers and insurance policies. In the opinion of management, there are no legal matters or claims likely to have a material adverse effect on the Company’s financial position, results of operations or cash flows. Other Commitments The Company has commitments under its lease obligations (Note 16). Contingencies The Company records a contingent liability when it is both probable that a loss has been incurred, and the amount can be reasonably estimated. If these estimates and assumptions change or prove to be incorrect, it could have a material impact on the Company’s consolidated financial statements. Contingencies are inherently unpredictable, and the assessments of the value can involve a series of complex judgments about future events and can rely heavily on estimates and assumptions. On May 23, 2016, the Company entered into a launch services agreement with a customer to provide three commercial dedicated launches which would deliver the customer’s payloads over the period of 2017 through 2021. Per the terms of the agreement, each dedicated launch shall have a firm fixed price below current launch vehicle costs. During the year ended December 31, 2018, the Company determined that it was probable that the costs to provide the services as stipulated by the launch services agreement would exceed the fixed firm price of each launch. As such, the Company recorded a provision for contract loss for these three dedicated launches. During the year ended December 31, 2021, one of the three launches occurred. On April 21, 2021, the launch services agreement was amended, resulting in one additional launch and the potential for price increases on the second and third launches dependent on the customer’s desired payload configuration. On March 29, 2023 and April 29, 2023, the launch services agreement was amended, to change the date by which the launch window election is to occur from March 31, 2023 to on or before May 31, 2023. In June 2023, the launch services agreement was terminated and as a result, the Company released a $ 4,066 provision for contract losses. F-38 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) In connection with the acquisition of SolAero Holdings, Inc. in January 2022, the Company assumed a contract with a customer to provide solar panel module at a fixed price. The Company determined that it was probable that the costs to complete the solar panel modules as stipulated by the contract would exceed the fixed firm price of the solar panel modules. As such, the Company recorded a provision for contract loss for this contract, of which $ 9,446 was recorded to other current liabilities in order to recognize the contract at fair value at acquisition. The provision for contract losses outstanding as of December 31, 2025, which primarily is related to the solar panel module agreement, was $ 4,999 included in other current liabilities in the Company’s consolidated balance sheets. 18.

Because of the Company’s recent history of operating losses in the U.S., we have recorded a full valuation allowance against our U.S. deferred tax assets. As of December 31, 2025 and 2024, we recorded valuation allowances of $ 304,106 and $ 236,113 , respectively. In 2025, the net increase in our valuation allowance primarily resulted from losses from operations, partially offset by the release of the valuation allowance related to the deferred tax liabilities generated from the GEOST acquisition. The One Big Beautiful Bill Act (OBBB), enacted on July 4, 2025, restores or makes permanent certain expiring business tax provisions from the Tax Cuts and Jobs Act of 2017. Among these changes, the OBBB reinstated the immediate expensing of domestic research and experimental (R&E) costs; however, R&E expenditures attributable to foreign research will continue to be capitalized and amortized over 15 years. Due to the full valuation allowance against our U.S. deferred tax assets, the impact of this legislative change is immaterial to our financial statements. The reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits for the years ended December 31, 2025 and 2024 is as follows: 2025 2024 Balance at beginning of year $ 939 $ 4,887 Decrease related to prior year tax positions — ( 1,974 ) Settlements — ( 1,974 ) Balance at end of year $ 939 $ 939 As of December 31, 2025 and 2024, the Company has unrecognized tax benefits totaling $ 140 and $ 140 , respectively, which, if recognized, would impact the effective tax rate in future periods. F-41 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) The Company recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision. As of December 31, 2025 and 2024, there were no accrued interest and penalties. Due to net operating loss (“NOL”) carryforwards, the U.S. federal and state returns are open to examination by the Internal Revenue Service and state jurisdictions for all years beginning with the year ended March 31, 2016. Our foreign subsidiaries are generally subject to examination within four years from the end of the tax year during which the tax return was filed. The years subject to audit may be extended if the entity substantially understates corporate income tax. The Company is not currently under examination by the IRS, foreign or state and local tax authorities. At December 31, 2025 and 2024, the Company had federal NOL carryforwards of $ 840,916 and $ 492,496 , respectively, which is comprised of definite and indefinite NOLs. The Company had definite federal NOL carryforwards of $ 57,135 as of December 31, 2025 and 2024, which begin to expire in varying amounts beginning in 2034. Federal NOLs generated after 2017 of $ 783,781 and $ 435,361 as of December 31, 2025 and 2024, respectively will carryforward indefinitely and are available to offset up to 80 % of future taxable income each year. The Company also had state NOL carryforwards of $ 549,464 and $ 428,696 as of December 31, 2025 and 2024, respectively, available to reduce future taxable income, if any. If not realized, the state NOLs will begin to expire in varying amounts beginning in 2035. Utilization of the net operating loss carryforwards may become subject to annual limitations due to ownership changes that could occur in the future as provided by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state and foreign provisions. These ownership changes may limit the amount of the net operating loss and tax credit carryforwards that can be utilized annually to offset future taxable income. As of December 31, 2025 and 2024, we have undistributed earnings of our foreign subsidiaries of $ 64,552 and $ 43,266 , respectively, which we have indefinitely reinvested and for which we have not recognized deferred taxes. The amount of unrecognized deferred taxes associated with these unremitted earnings would not be significant at December 31, 2025 and 2024. The income taxes paid by jurisdiction or the year ended December 31, 2025 consisted of the following: Jurisdiction Year Ended December 31, 2025 Federal $ — State — Foreign 854 Canada 756 New Zealand 91 Other 7 Total $ 854 F-42 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) 19. NET LOSS PER SHARE Common Stock The holder of each share of common stock has the right to one vote for each share and is entitled to notice of any stockholders’ meeting and to vote upon certain events. Preferred Stock The holder of the Preferred Stock has similar rights and characteristics to common stock and for the purposes of the calculation of earnings per share, the Preferred Stock is treated as common stock. Earnings Per Share Calculation Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during each period. Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common and dilutive common equivalent shares outstanding for the period using the treasury-stock method and the if-converted method, whichever is more dilutive. Potentially dilutive shares are comprised of common stock warrants, restricted stock units, stock options and shares underlying our convertible senior notes. For the years ended December 31, 2025, 2024 and 2023, there is no difference in the number of shares used to calculate basic and diluted shares outstanding due to the Company’s net loss and potentially dilutive shares being anti-dilutive. The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company for the years ended December 31, 2025, 2024 and 2023: Years Ended December 31, 2025 2024 2023 Numerator Net loss attributable to common stockholders-basic and diluted $ ( 198,209 ) $ ( 190,175 ) $ ( 182,571 ) Denominator Weighted average common shares outstanding-basic and diluted 530,664,781 495,929,861 481,768,060 Net loss per share attributable to common stockholders-basic and diluted $ ( 0.37 ) $ ( 0.38 ) $ ( 0.38 ) The following equity shares were excluded from the calculation of diluted net loss per share attributable to common stockholders because their effect would have been anti-dilutive for the years ended December 31, 2025, 2024 and 2023: December 31, 2025 2024 2023 Stock options and restricted stock units 17,409,519 28,913,838 26,889,125 Common stock warrants — — 728,835 Shares underlying our convertible senior notes 30,368,547 69,261,530 — F-43 Table of Contents ROCKET LAB CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) (In thousands, except share and per share data) 20. SEGMENTS The Company’s CODM reviews financial information presented based on a management approach for the purposes of making operating decisions, assessing financial performance and allocating resources. The CODM uses gross profit as the measure of segment profit or loss to assess performance and allocate resources. The Company manages its business primarily based upon two operating segments, launch services and space systems. Each of these operating segments represents a reportable segment. Launch Services provides launch and launch related services to customers on a dedicated mission or ride share basis. Space systems is predominately comprised of spacecraft components and spacecraft manufacturing. Although some of the Company’s contracts with customers contain elements of space systems and launch services, each reporting segment is managed separately to better align with customer’s needs and the Company’s growth plans. The accounting policies of the various segments are the same as those described in Note 2. For contracts with customers that contain both space systems and launch services elements, revenues for each reporting segment are generally allocated based upon the overall costs incurred for each of the reporting segments in comparison to total overall costs of the contract. The following table shows information by reportable segment for the years ended December 31, 2025, 2024 and 2023: Years Ended December 31, 2025 2024 2023 Launch Services Space Systems Launch Services Space Systems Launch Services Space Systems Revenues $ 199,042 $ 402,757 $ 125,376 $ 310,838 $ 71,894 $ 172,698 Cost of revenues 117,772 276,846 90,786 229,279 63,827 129,356 Gross profit $ 81,270 $ 125,911 $ 34,590 $ 81,559 $ 8,067 $ 43,342 The following table shows information by reportable segment by products and services for the years ended December 31, 2025, 2024 and 2023: Years Ended December 31, 2025 2024 2023 Launch Services Space Systems Launch Services Space Systems Launch Services Space Systems Products: Revenues $ — $ 371,617 $ — $ 289,851 $ — $ 156,560 Cost of revenues — 252,848 — 213,835 — 115,342 Gross profit $ — $ 118,769 $ — $ 76,016 $ — $ 41,218 Services: Revenues $ 199,042 $ 31,140 $ 125,376 $ 20,987 $ 71,894 $ 16,138 Cost of revenues 117,772 23,998 90,786 15,444 63,827 14,014 Gross profit $ 81,270 $ 7,142 $ 34,590 $ 5,543 $ 8,067 $ 2,124 Management does not regularly review either reporting segment’s total assets or operating expenses. This is because in general, the Company’s long-lived assets, facilities, and equipment are shared by each reporting segment. 21.
