The going concern basis of presentation assumes that the Company will continue in operation one year after the date these unaudited condensed consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of ASC Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these unaudited condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within the control of the Company as of the date the unaudited condensed consolidated financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the unaudited condensed consolidated financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern over the next twelve months through May 2025. Since inception, the Company has incurred significant operating losses and has an accumulated deficit of approximately $ 2.0 billion . As of March 31, 2024, the Company’s existing sources of liquidity included cash and cash equivalents of $ 6.6 million (including $ 3.5 million of funds that the Company may only use for specified purposes pursuant to the Merger Agreement) and restricted cash of $ 0.5 million. The restricted cash is related to a letter of credit issued to secure our performance obligations under a customer contract and is not accessible until we have begun delivery of flight sets for this customer's program which is expected to be in November 2024 pursuant to the contract schedule. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and sale of its services and products. To proceed with the Company’s business plan and continue the Company's business operations, the Company will need to raise substantial additional funds through the issuance of additional debt, equity or both. Under the terms of the Merger Agreement, the Company is restricted from incurring new debt or issuing equity except through the offer and sale of the convertible notes due November 15, 2025 (the "Convertible Notes") and warrants to purchase shares of Class A Common Stock at an exercise price of $ 0.808 per share, in each case under the terms of the Subsequent Financing Agreement (as defined in Note 6). The term “Company Warrants” means and includes all warrants issued under the Subsequent Financing Agreement, together with warrants to purchase 1.5 million shares of Class A Common Stock issued on August 4, 2023. See Note 6 — Convertible Notes and Company Warrants. The Merger Agreement further prohibits the Company from issuing Convertible Notes or Company Warrants to any person prior to the consummation of the Merger unless (i) such person becomes a noteholder under the Noteholder Conversion Agreement, respectively, by executing a joinder agreement substantially in the form attached to such agreement and delivering the same to each of Merger Sub and Parent and (ii) holders of a majority in interest of the Convertible Notes or Warrants, as applicable, then outstanding consent to such issuance and joinder, all of which may affect the Company’s ability to raise additional funds from the sale of its Convertible Notes and Company Warrants on the timing needed. If the Company is unable to obtain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. The Company may be required to delay, limit, reduce or terminate its product development activities or future commercialization efforts or cease business operations, including through a petition for voluntary relief under Chapter 7 of the United States Bankruptcy Code (a “Chapter 7 Liquidation”). There can be no assurance that the Company will be able to obtain the needed financing on acceptable terms or on terms that would be permissible under the restrictions imposed by the Merger Agreement. As a result of these uncertainties, and notwithstanding management’s plans and efforts to date, there is substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. If the Company is unable to raise substantial additional capital in the near term and as necessary to continue the Company's operations prior to the closing of the Merger, the Company’s operations and production plans may be further scaled back or curtailed or cease entirely, and the Company may be required to furlough employees to manage its short term cash needs. Further, the Company may be required to file a Chapter 7 Liquidation and in such case, may not realize any significant value from its assets in connection with a liquidation. The Company has, however, prepared these unaudited condensed consolidated financial statements on a going concern basis, assuming that the Company's financial resources will be sufficient to meet its capital needs over the next twelve months. Accordingly, the Company's financial statements do not include adjustments relating to the recoverability and realization of assets and classification of liabilities that might be necessary should it be unable to continue in operation for the next twelve months. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company maintains cash and cash equivalent balances in bank accounts with multiple banking partners. All cash accounts are located in the United States (“U.S.”) and insured by the FDIC up to $ 250,000 . The Company's accounts receivables represent unconditional rights to consideration. The Company mitigates collection risks from its customers by performing regular credit evaluations of the Company's customers’ financial conditions. The Company believes there is no exposure to any significant credit risks related to its cash and cash equivalents or accounts receivable and has not experienced any losses in such accounts. The following customer's outstanding accounts receivable accounted for greater than 10% of the Company's trade accounts receivable as of the date reflected: March 31, 2024 December 31, 2023 Customer 1 88.9 % 92.4 % For the three months ended March 31, 2024 and 2023, one customer accounted for greater than 10% of the Company's total revenues: Three Months Ended 2024 2023 Customer 2 100.0 % — ____________ Use of Estimates and Judgments The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the unaudited condensed consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ significantly from those estimates. Significant items subject to such estimates and assumptions include the valuation of our Convertible Notes and Company Warrants and long-lived assets, inventory valuation and reserves, stock-based compensation, useful lives of intangible assets and property, plant and equipment, deferred tax assets, income tax uncertainties and other contingencies. Significant Accounting Policies There have been no changes to the Company’s significant accounting policies described in the Company’s 2023 Annual Report that have had a material impact on its unaudited condensed consolidated financial statements and related notes. Recently Adopted Accounting Standards There have been no new accounting standards applicable to the Company that have been adopted during the three months ended March 31, 2024. Recently Issued Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB") issued Accounting Standards Update (“ASU") 2023-09 (ASC Topic 740), Improvements to Income Tax Disclosures ("ASU 2023-09"). This ASU requires disaggregated income tax disclosures on the rate reconciliation and income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 for publicly traded companies and December 15, 2025 for private companies. Early adoption is permitted for annual financial statements not yet issued or made available for issuance. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 updates reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance. ASU 2023-07 is effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures. In March 2024, the SEC adopted new rules that will require registrants to provide certain climate-related information in their registration statements and annual reports. The rules require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks will also include disclosure of a registrant's greenhouse gas emissions. In addition, the rules will require registrants to present certain climate-related financial metrics in their audited financial statements. The Company is currently evaluating the rules and the impact on its future consolidated statements. The Company also notes that on April 4, 2024, the SEC voluntarily stayed implementation of its recently adopted climate disclosure rules pending the outcome of certain legal challenges to the rules.

Revenues [Abstract]
Revenues	Note 2 — Revenues The Company recognizes revenue at a point in time upon satisfaction of the performance obligations under its Launch Services and Space Products agreements. The following table presents revenue disaggregated by type for the periods presented: Three Months Ended in thousands 2024 2023 Launch services $ — $ — Space products 285 — Total revenues $ 285 $ — Contracts with governmental entities involving research and development milestone activities do not represent contracts with customers under ASC 606 and as such, amounts received are recorded in other income in the unaudited condensed consolidated statements of operations. The Company recorded no other income during the three months ended March 31, 2024 and 2023. Contract balances Contract assets and liabilities reflect timing differences between the receipt of consideration and the fulfillment of performance obligations under a contract with a customer. Contract assets reflect performance obligations satisfied and revenues recognized in advance of a customer billing. Contract liabilities reflect consideration received in advance of the satisfaction of a performance obligation under a contract with a customer. Contract assets become trade receivables once the Company's rights to consideration become unconditional. Such rights are considered unconditional if only the passage of time is required before payment of that consideration is due. Contract costs are those costs which are directly related to fulfillment of specified customer contracts. The Company had deferred contract costs of $ 3.7 million and $ 2.2 million as of March 31, 2024 and December 31, 2023, respectively. The Company had contract liabilities of $ 49.6 million and $ 40.4 million as of March 31, 2024 and December 31, 2023, respectively. During the three months ended March 31, 2024 , the Company did no t recognize any revenue that was included in the contract liabilities balance at the beginning of the period. For the three months ended March 31, 2023, the C ompany recorded no revenue that was included in the contract liabilities balance at the beginning of the period. Remaining performance obligations Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied. It includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods and does not include contracts where the customer is not committed. Customers are not considered committed when they are able to terminate their contractual obligations to the Company without payment of a substantial penalty under the contract. The Company had unsatisfied performance obligations based on contractual terms of $ 70.0 million as of March 31, 2024, all of which is expected to be achieved between October 2024 an d 2028.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5 — Fair Value Measurements The Company measures its financial assets and liabilities at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value, as follows: Level 1 Observable inputs, such as quoted prices in active markets for identical assets or liabilities; Level 2 Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3 Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts of the Company's cash equivalents, accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities and certain other current liabilities approximate fair value because of their short-term maturities. As of March 31, 2024 and December 31, 2023 , the Company had a total of $ 5.8 million and $ 18.6 million, respectively, of liabilities related to its Company Warrants and $ 28.2 million and $ 63.5 million, respectively, of Convertible Notes, both of which are recorded at fair value as of the period presented. The Company elected to account for the Convertible Notes on a fair value basis under ASC 825 to comprehensively value and streamline the accounting for the embedded conversion options. For a description of the valuation models used and the fair value inputs applied by the Company in determining the fair values of the Convertible Notes and Company Warrants, see Note 6 — Convertible Notes and Company Warrants under the captions "Fair Value Option of Accounting For Convertible Notes" and "Fair Value of Warrants." The following table presents information about the Company’s liabilities at March 31, 2024, that were measured at fair value on a recurring basis: in thousands March 31, 2024 Description Level 1 Level 2 Level 3 Total Liabilities: Warrants to purchase common stock $ — $ — $ 5,781 $ 5,781 Convertible Notes — — 28,211 28,211 Total financial liabilities $ — $ — $ 33,992 $ 33,992 in thousands December 31, 2023 Description Level 1 Level 2 Level 3 Total Liabilities: Warrants to purchase common stock $ — $ — $ 18,554 $ 18,554 Convertible Notes — — 63,520 63,520 Total financial liabilities $ — $ — $ 82,074 $ 82,074 The following table presents a summary of the changes in fair value of the Company's Level 3 financial i nstruments: in thousands Warrants Fair value as of December 31, 2023 $ 18,554 Issuance of warrants at fair value 2,234 Gain on change in fair value of warrants ( 15,007 ) Fair value as of March 31, 2024 $ 5,781 in thousands Convertible Notes Fair value as of December 31, 2023 $ 63,520 Issuance of convertible notes at fair value 11,961 Gain on change in fair value of convertible notes ( 47,270 ) Fair value as of March 31, 2024 $ 28,211 The $ 15.0 million gain on change in fair value of warrants during the three months ended March 31, 2024 is primarily the result of a change in the exercise price from $ 0.808 per warrant share to $ 0.404 per warrant share when the warrants are exchanged for warrants of Series A Preferred Stock in Parent in connection with the consummation of the Merger pursuant to the warrant exchange agreements entered by the Parent and the holders of Company Warrants. The $ 47.3 million gain on the change in fair value of Convertible Notes during the three months ended March 31, 2024 is primarily due to the change in conversion price pursuant to the terms of the noteholder conversion agreement that will take effect upon completion of the Merger

(2) The CEO and CTO made additional investments in Convertible Notes of $ 150,000 each on February 26, 2024. No Company Warrants were issued with to the CEO or CTO with this additional investment. See Note 15 — Subsequent Events for information on additional sales of Convertible Notes and Company Warrants occurring after March 31, 2024. Material Amendments to Subsequent Financing Agreement and Convertible Notes On November 21, 2023, the Company entered into an Omnibus Amendment No. 3 Agreement, dated as of November 21, 2023, which agreement, subject to amendments occurring after such date, sets forth the terms and conditions upon which the Company may offer for sale and issue Convertible Notes and Company Warrants (the “Subsequent Financing Agreement”). During the three months ended March 31, 2024, the Company and the holders of the Convertible Notes and Company Warrants amended or modified the Subsequent Financing Agreement and the Convertible Notes on January 19, 2024 (the “January 19 Amendment”), January 31, 2024 (the “January 31 Amendment”) and February 26, 2024 (the “February Amendment”). The January 19 Amendment extended the date by which a Subsequent Closing (as defined the Subsequent Financing Agreement) may occur without the consent of a majority-in-interest of the Convertible Notes from January 20, 2024, to February 19, 2024, which date was further extended by the February Amendment to April 30, 2024. The January 31 Amendment extended the first amortization payment under the Convertible Notes, which was originally due on February 1, 2024, to May 1, 2024. The February Amendment also increased the maximum amount of the Aggregate Stated Principal Amount (as defined in the Subsequent Financing Agreement) of the Convertible Notes from $ 25.0 million to $ 35.0 million, which amount was subsequently increased to $ 50.0 million pursuant to the April Amendment. See Note 15 – Subsequent Events for information about additional amendments to the Subsequent Financing Agreement and Convertible Notes occurring after March 31, 2024. Fair Value of Company Warrants and Convertible Notes Company Warrants As of March 31, 2024, the Company had 14,823,917 Company Warrants issued and outstanding which are included in Warrants to purchase common stock on the consolidated balance sheets at fair value of $ 5.8 million. This does not include an immaterial number of warrants issued to ShareIntel-Shareholder Intelligence Services LLC (the “ShareIntel Warrants”). The Company has determined the Company Warrants are liability classified financial instruments and are required to be measured at fair value at issuance and subsequently at each reporting date, with changes in fair value included in earnings of the period. The Company determined the fair value of the Company Warrants issued during the three months ended March 31, 2024 and of all Company Warrants outstanding as of March 31, 2024 based on an option pricing model ("OPM") considering the warrant exchange agreement between the Parent and holders of Company Warrants and the expected capital structure of the Parent following consummation of the Merger The following is a summary of the assumptions used to determine the OPM fair value of the Company Warrants at each date of issuance and for all Company Warrants outstanding as of March 31, 2024: January 19, March 6, (1) (2) March 31, Expected terms (years) 3.45 3.32 3.25 Expected volatility 75.00 % 80.00 % 75.00 % Risk-free interest rate 4.07 % 4.20 % 4.28 % Expected dividend rate — — — Value per share $ 0.39 $ 0.40 $ 0.39 Exercise price $ 0.40 $ 0.40 $ 0.40 Implied Negotiation Discount 32.20 % 31.50 % 31.50 % (1) The Subsequent Financings that occurred on March 7, 2024, March 8, 2024 and March 15, 2024 applied the same fair value model and assumptions as those used for Subsequent Financing that occurred on March 6, 2024. (2) Subsequent Financings that occurred on February 26, 2024 and March 8, 2024 did not include the purchase of Company Warrants. The expected term is based on expectations with regard to an exit strategy such as an IPO or liquidation event of the Parent. The risk free rate was based on the rate of treasury securities with the same term as the option. The expected volatility was based on guideline company indications. As of December 31, 2023, the Company had 9,196,627 of Company Warrants issued and outstanding with a fair value of $ 18.5 million. The Company utilized the Black-Scholes Option Pricing model to determine the fair value of the Company Warrants outstanding at that date. The following is a summary of the assumptions applied to determine the Black-Scholes fair value of the outstanding Company Warrants as of December 31, 2023: December 31, Expected terms (years) 4.6 Expected volatility 109.8 % Risk-free interest rate 3.84 % Expected dividend rate — Value per share $ 2.28 Exercise price $ 0.81 Convertible Notes During the three months ended March 31, 2024, the Company issued $ 14.2 million principal amount of Convertible Notes and as of March 31, 2024, had a total of $ 31.8 million Convertible Notes principal with an aggregate fair value of $ 28.2 million. The Company has elected the fair value option for accounting for all of its Convertible Notes. The fair values of the Convertible Notes issued during the three months ended March 31, 2024 were determined as the residual value of the total proceeds received less the fair value of the Company Warrants issued concurrently with the Convertible Notes. The fair value of the Convertible Notes as of March 31, 2024, was determined by the total merger consideration derived from the total principal, paid-in-kind interest and accrued interest through the assumed date of merger, less an assumed negotiated discount derived from the Convertible Notes issuances during the three months ended March 31, 2024. As of December 31, 2023, the Company had $ 17.8 million principal amount of Convertible Notes outstanding. The Company utilized the Monte Carlo Simulation Model to determine the fair value of the Convertible Notes outstanding as of December 31, 2023. The following is a summary of the assumptions applied in determining the fair value of the Convertible Notes as of December 31, 2023: December 31, Risk-free interest rate 4.21 % Risk adjusted interest rate (for discount payment) 71.0 % Value per share $ 2.28 Volatility 35.50 %

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 7 — Commitments and Contingencies Legal Proceedings The Company is party to ordinary and routine litigation incidental to its business. On a case-by-case basis, the Company engages inside and outside counsel to assess the probability of potential liability resulting from such litigation. After making such assessments, the Company makes an accrual for the estimated loss only when the loss is probable, and an amount can be reasonably estimated. The Company and or its current or former directors and officers are currently parties to the following litigation matters: On April 27, 2022, a stockholder derivative suit was filed in the United States District Court for the Eastern District of New York styled Gonzalez v. Kemp, et al., Case No. 22-cv-02401 (E.D.N.Y.) (the “Gonzalez Action”). On January 25, 2023, the plaintiff filed an amended complaint. The amended complaint asserts claims against certain of the Company’s current and former officers and directors for alleged breaches of their fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, alleged violations of Section 14(a) of the Securities Exchange Act of 1934 (the “Exchange Act”), and for contribution under Section 10(b) and 21D of the Exchange Act based upon the conduct alleged in the Securities Action described above. The plaintiff in the Gonzalez Action seeks monetary damages in favor of the Company in an unstated amount, reforms to the Company’s corporate governance and internal procedures, restitution including disgorgement of any compensation, profits or other benefits received, and reimbursement of the plaintiff's reasonable fees and costs, including attorney’s fees. On February 17, 2023, the Gonzalez Action was transferred to the United States District Court for the Northern District of California under Case No. 3:23-cv-00713. Defendants filed a motion to dismiss the amended complaint on April 18, 2023. On June 12, 2023, the Court in the Gonzalez Action granted the Company’s motion to stay the case until a final judgment has been issued in the resolution of In re Astra Space f/k/a Holicity Inc. Securities Litigation (Case No. 3:22- cv-08875) in the Northern District of California (the “Securities Action. Once the Securities Action was dismissed, the Gonzalez Action again proceeded. Plaintiffs have filed an opposition to the Defendants motion to dismiss. Due to the announcement of the potential merger transaction (and the likely alternative of bankruptcy if the merger transaction does not close), the Court has again stayed the Gonzalez Action until at least July 9, 2024. The Company believes that the case is without merit and intends to defend it vigorously. Due to the early stage of the case, neither the likelihood that a loss, if any, will be realized, nor an estimate of the possible loss or range of loss, if any, can be determined. Based on a Court of Chancery Rule 5.1 notice, on or about June 30, 2023 , a stockholder derivative suit was filed in the Delaware Court of Chancery styled Capani v. Chris C. Kemp, et al., C.A. No. 2023-0676- (“Capani Action”). The Capani Action appears to be brought by the same plaintiff who filed the first derivative complaint in the District Court of Delaware in early 2022. The first derivative complaint was voluntarily dismissed without prejudice after the Company filed a motion to dismiss. On July 31, 2023, the Chancery Court entered a stipulated stay of the case pending the resolution of the Securities Action for which an order granting the Company’s motion to dismiss was entered on August 2, 2023. The stay was lifted upon the Securities Action’s resolution. No motion to dismiss briefing schedule has since been entered in this case. The stockholder subsequently served a books and records demand before filing the present lawsuit. The Company believes that the case is without merit and intends to defend it vigorously. Due to the early stage of the case, neither the likelihood that a loss, if any, will be realized, nor an estimate of the possible loss or range of loss, if any, can be determined. The Company has tendered defense of each of the foregoing claims under its Directors’ and Officers’ policy. The retention under this policy is $ 20.0 million. Indemnification Obligations to former Company Board Members On May 20, 2022, a putative class action was filed in the Court of Chancery of the State of Delaware styled Newbold v. McCaw et. al., Case No. 2022-0439 (the “Newbold Action”). The complaint alleges that Pendrell Corporation, X-icity Holdings Corporation f/k/a Pendrell Holicity Holdings and certain former officers, directors or controlling stockholders of Holicity, Inc. n/k/a Astra Space, Inc., breached their fiduciary duties to the Company in closing on the Business Combination. The complaint seeks unspecified damages on behalf of a purported class of stockholders of the Company’s securities during a specified time period. Neither the Company nor any of its board members are parties in this action. Mr. McCaw, who served as a former member of the Company’s board, is a defendant in this action, but the allegations relate to periods prior to the Business Combination. Astra is obligated to indemnify certain of the defendants in the Newbold Action. The Company has tendered defense of this action under its Directors’ and Officers' Policy. The Company also tendered defense of this claim under the tail policy it was required to purchase in connection with the Business Combination. The retention under the tail policy is $ 1.5 million. Due to the early stage of this case, neither the likelihood that a loss, if any, will be realized, nor an estimate of the possible loss or range of loss, if any, can be determined. On or about July 21, 2023 , the Delaware Chancery Court denied the defendants’ motion to dismiss the amended complaint. Section 220 Demands Following the announcement of the Merger Agreement, the Company has received demands to inspect the Company’s books and records pursuant to 8 Del. C. § 220 (“Section 220”). Specifically, on April 5, 2024, purported stockholder Jonathan Horner delivered a Section 220 demand to the Company, which demand was supplemented on April 11, 2024. On April 17, 2024, another purported stockholder, Michael Krene, represented by the same law firm, delivered a second Section 220 demand to the Company. On April 22, 2024, a third purported stockholder, Jerry Hamelton, delivered a Section 220 demand to the Company (collectively, the “Section 220 Demands”). Although the specifics of each Section 220 Demand varies, they generally intend to investigate the events leading to execution of the Merger Agreement, to investigate the independence and disinterestedness of certain members of the Company’s board of directors and officers in connection with the Merger Agreement and the Merger, and to determine whether such directors and officers properly discharged their fiduciary duties, investigate the Company’s disclosures regarding the Merger Agreement and the Merger. The Section 220 Demands seek to inspect the Company’s books and records to determine whether wrongdoing, mismanagement, and/or material non-disclosure has taken place such that it would be appropriate to file an action against the Board, the officers, the Company, or any other relevant person or entity, to value each stockholder’s shares, and to consider any other courses of action that the investigation might warrant pursuing. The Company is evaluating each of the Section 220 Demands and intends to defend vigorously any allegation of wrongdoing, mismanagement and/or non-disclosure. Due to the early stage of these investigations, neither the likelihood that a loss, if any, will be realized, nor an estimate of the possible loss or range of loss, if any, can be determined. Commercial Contracts The Company has received notices of termination from two customers. The total contract value of these two agreements was $ 15.4 million, with current contract liabilities of $ 7.8 million and non-current liabilities of $ 1.9 million. There are disputes with both customers regarding certain aspects of the terminations, including the financial impact. In particular, the parties are disputing whether the customer has rights to refunds, and for any additional payments due to the Company. The Company believes it has valid defenses against claims for refunds from these two customers, and may have valid claims for the additional payments. The Company further hopes to negotiate a mutually agreeable resolution to these disputes and believes it is premature to estimate any potential liabilities or contingencies in connection with these two contract terminations. Purchase Commitments In order to reduce manufacturing lead times and to have access to an adequate supply of components, the Company enters into agreements with certain suppliers to procure component inventory based on the Company's production needs. A significant portion of the Company's purchase commitments arising from these agreements consist of firm and non-cancelable commitments. We have one such supplier contract which is active at this time. While we are currently in a dispute with this supplier over the performance of this contract, there remains $ 20.1 million in purchase obligations under the contract.

Share-Based Payment Arrangement [Abstract]
Share-based Payment Arrangement	Note 8 — Stock-based Compensation Stock-based incentive awards are provided to employees under the terms of Astra's 2021 Omnibus Incentive Plan (the “2021 Plan”) and the 2023 Bonus Incentive Plan and 2021 Employee Stock Purchase Plan (the “2021 ESPP”). Unless otherwise noted, all share and per share amounts below have been restated to give effect to the Reverse Stock Split on September 13, 2023. For the impact of the Reverse Stock Split on prior period comparable share and per share amounts and additional information related to the Reverse Stock Split , see Note 1 – Description of Business, Basis of Presentation and Significant Accounting Policies. There was a $ 6.0 million reversal of accrued costs associated with the 2023 Bonus Incentive Program as of December 31, 2023 , and $ 0.7 million recognized for the quarter ended March 31, 2023. As of March 31, 2024, the Company has not established a 2024 Bonus Incentive Plan and as such, no performance-based stock options have been granted for the quarter ended March 31, 2024. The following table summarizes stock-based compensation expense for the three months ended March 31, 2024 and 2023: Three Months Ended in thousands 2024 2023 Cost of revenues $ — $ — Research and development 1,268 2,359 Sales and marketing 392 380 General and administrative 1,849 2,589 Stock-based compensation expense $ 3,509 $ 5,328 The Company did no t recognize any compensation cost related to performance-based stock units (“PSUs”) for the three months ended March 31, 2024. For the three months ended March 31, 2023, the Company recognized $ 0.1 million in compensation costs related to PSUs. As of March 31, 2024, the Company had $ 20.6 million of unrecognized stock-based compensation expense related to all of the Company's stock-based awards. This cost is expected to be recognized over a weighted-average period of 2.01 years. Stock Options Awards The following is a summary of stock option activity for the three months ended March 31, 2024: No. of Weighted- Average Exercise Price Weighted- Average Aggregate Intrinsic Outstanding – December 31, 2023 1,320,540 $ 24.13 8.40 $ 128,212 Granted 15,494 1.52 3.08 — Exercised ( 300 ) 0.90 — — Forfeited/Cancelled ( 271,972 ) 7.08 — — Expired ( 41,440 ) 12.52 — — Outstanding – March 31, 2024 1,022,322 $ 28.79 8.10 $ — Unvested – March 31, 2024 670,064 18.89 8.77 — Exercisable – March 31, 2024 352,258 $ 47.63 6.82 $ — The Company uses the Black-Scholes option pricing-model to calculate the grant date fair value of time-based and performance-based options. The following table summarizes the assumptions used in estimating the fair value of options granted in the three months ended March 31, 2024 and 2023: Three Months Ended March 31, 2024 2023 Expected terms (years) 6.13 6.71 Expected volatility 109.7 % 98.2 % Risk-free interest rate 4.07 % 3.46 % Expected dividend rate — — Grant-date fair value $ 1.52 $ 0.42 - $ 0.56 ____________ (1) The expected term is the length of time the grant is expected to be outstanding before it is exercised or terminated. This number is calculated as the midpoint between the vesting term and the original contractual term (contractual period to exercise). If the option contains graded vesting, then the vesting term would be based on the vesting pattern. (2) Expected volatility, or the standard deviation of annualized returns, was calculated based on the Company's common stock price history for the expected term as of the valuation date. (3) Risk-free interest was obtained from U.S. treasury notes for the expected terms noted as of the valuation date . (4) The Company has assumed a dividend yield of zero as it has no plans to declare dividends in the foreseeable future . Restricted Stock Units ("RSU") Awards The following is a summary of restricted stock units for the three months ended March 31, 2024: Number of RSUs Outstanding Weighted- Average Grant Date Fair Value Per Share Outstanding – December 31, 2023 594,238 $ 33.60 Granted — — Vested ( 46,676 ) 50.78 Forfeited ( 41,988 ) 44.22 Outstanding – March 31, 2024 505,574 $ 31.13 Total fair value as of the respective vesting dates of restricted stock units vested for the three months ended March 31, 2024 was approximately $ 0.1 million . As of March 31, 2024, the aggregate intrinsic value of unvested restricted stock units was $ 0.3 million . 2021 ESPP The 2021 ESPP, which is maintained by the Company, allows employees to purchase the Company’s common 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 six-month purchase period. On December 21, 2023, the Board cancelled the Plan effective immediately following the next purchase date during the quarter ended March 31, 2024, where the Company issued 76,191 shares on January 19, 2024 at a cost of $ 0.01 million. The remaining 481,866 shares issuable under the 2021 ESPP were returned to the pool of Class A common stock available for issue. As of March 31, 2024 , the Company had no remaining unrecognized stock-based compensation expense related to the 2021 ESPP.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 9 — Income Taxes The Company computes its provision for income taxes by applying the estimated annual effective tax rate to year-to-date income from recurring operations and adjusts the provision for discrete tax items recorded in the period. There has historically been no federal or state provision for income taxes because the Company has incurred operating losses and maintains a full valuation allowance against its net deferred tax assets. For the three months ended March 31, 2024 and 2023 , the Company recognized no provision for income taxes consistent with the losses incurred and the valuation allowance against the deferred tax assets. Utilization of net operating loss carryforwards, tax credits and other attributes may be subject to future annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions. The Company files income tax returns in the U.S. federal jurisdiction and various states. The Company is not currently under examination by income tax authorities in federal, state or other jurisdictions. All tax returns will remain open for examination by the federal and state authorities for three and four years, respectively, from the date of utilization of any net operating loss or credits.

Earnings Per Share [Abstract]
Income (Loss) per Share	Note 10 — Income (Loss) per Share The Company computes earnings (loss) per share of Common Stock using the two-class method required for participating securities. Basic earnings (loss) per common share is determined based on the weighted-average number of common shares outstanding during each period. For periods with net income, the Company gives effect to all dilutive potential common shares outstanding during a period. The Company uses the control number concept to determine whether a potential common stock instrument is dilutive, and considers each issuance separately for its potential dilution in order of the most dilutive issuance to the least. For periods with net loss, diluted earnings per share will consider whether the inclusion of all potential Common Stock outstanding would be anti-dilutive. The dilutive effect of outstanding options and warrants is calculated using the treasury stock method. The dilutive effect of shares underlying the Company's Convertible Notes is calculated using the if-converted method in periods during which Convertible Notes are available for conversion. The following tables set forth the computation of basic and diluted income (loss) for the three months ended March 31, 2024 and 2023: Three Months Ended March 31, 2024 2023 (in thousands, except share and per share amounts) Class A Class B Class A Class B Numerator Net income (loss) attributed to common stockholders - Basic $ 31,902 $ 6,227 $ ( 35,667 ) $ ( 9,226 ) Gain on change in fair value of Warrants ( 12,523 ) ( 2,444 ) — — Gain on change in fair value of Convertible Notes ( 38,508 ) ( 7,516 ) — — Net loss - Diluted $ ( 19,129 ) $ ( 3,734 ) $ ( 35,667 ) $ ( 9,226 ) Denominator Weighted-average common shares outstanding - Basic 18,969,208 3,702,613 14,313,785 3,702,613 Effect of dilutive securities: Common shares issuable for Warrants 3,551,766 693,272 — — Common shares issuable for Convertible Notes 18,820,895 3,673,664 — — Weighted-average common shares outstanding - Diluted 41,341,869 8,069,548 14,313,785 3,702,613 Net income (loss) per share - Basic $ 1.68 $ 1.68 $ ( 2.49 ) $ ( 2.49 ) Net loss per share - Diluted $ ( 0.46 ) $ ( 0.46 ) $ ( 2.49 ) $ ( 2.49 ) There were no preferred dividends declared or accumulated as of March 31, 2024. As of March 31, 2024 there were 39,969,265 equivalent shares of Class A Common Stock underlying the Convertible Notes outstanding principal, paid in-kind interest and accrued but uncapitalized interest. The Convertible Notes, which are immediately convertible by the holder into equivalent shares of Class A Common Stock shares, are excluded from the diluted weighted average shares when their effect would be anti-dilutive. The following Class A securities were not included in the computation of diluted shares outstanding because the effect would be anti-dilutive: March 31, 2024 2023 Stock options 1,022,322 1,062,625 RSUs 505,574 968,879 Convertible Notes 17,474,706 — Warrants 5,627,290 1,667 Total 24,629,892 2,033,171 There were no Cla ss B securities that were excluded in the computation of diluted shares outstanding for the three months ended March 31, 2024 and 2023 .

Segment Reporting [Abstract]
Segment Information	Note 11 — Segment Information The Company reports segment information based on a “management” approach to reflect the operating segments for which the Company’s Chief Executive Officer, as the Chief Operating Decision Maker (“CODM”), makes decisions and assesses performance. The Company has two operating and reporting segments: Launch Services and Space Products. Launch Services segment provides rapid, global, and affordable launch services to satellite operators and governments. Space Products consist of designing and providing space products based on the customers' needs for a successful satellite launch. All intercompany revenues and expenses are eliminated in the consolidated financial statements. The following table shows revenue by reporting segment for the three months ended March 31, 2024 and 2023: Three Months Ended in thousands 2024 2023 Revenues: Launch services $ — $ — Space products 285 — Total revenues: $ 285 $ — Cost of revenues: Launch services $ — $ — Space products 128 — Total cost of revenues: $ 128 $ — Gross profit: Launch services $ — $ — Space products 157 — Total gross profit: $ 157 $ — The Company evaluates the performance of its reporting segments based on segment gross profit. Segment gross profit is segment revenue less segment cost of revenue. Unallocated expenses include operating expenses related to research and development, selling and marketing and general and administrative expenses as they are not considered when management evaluates segment performance. The following table reconciles segment gross profit to loss before income taxes for the three months ended March 31, 2024 and 2023: Three Months Ended in thousands 2024 2023 Gross profit $ 157 $ — Research and development 12,641 31,082 Selling and marketing 865 2,484 General and administrative 11,036 15,682 Gain on change in fair value of contingent consideration — ( 2,765 ) Interest income ( 5 ) ( 1,330 ) Other income, net ( 232 ) ( 260 ) Gain on change in fair value of Convertible Notes ( 47,270 ) — Gain on change in fair value of warrants ( 15,007 ) — Income (loss) before taxes $ 38,129 $ ( 44,893 ) The Company does not evaluate performance or allocate resources based on reporting segment’s total assets or operating expenses, and therefore such information is not presented. All of the Company’s long-lived assets are located in the United States. The Company is subject to International Traffic in Arms Regulations (“ITAR”) and generates all of its revenue in the United States.

As a result of the Merger, the Company will cease to be a publicly traded company and it will be wholly owned by Parent. At the Effective Time, by virtue of the occurrence of the Merger, the following will occur: • each share of Class A Common Stock or Class B Common Stock (each a “Common Share”) that is owned by the Company as treasury shares and each Common Share that is owned by any direct or indirect wholly owned subsidiary of the Company, or by Parent, Merger Sub, or any direct or indirect wholly owned subsidiary of Parent or Merger Sub, in each case, issued and outstanding immediately prior to the Effective Time, will automatically be canceled without payment of any consideration therefor and cease to exist (the “Canceled Common Shares”); • each share of Class A Common Stock (each a “Class A Share”) for which the holder thereof did not consent or vote in favor of the Merger Agreement and is entitled to and properly demands appraisal pursuant to the DGCL, and does not withdraw or otherwise lose the right to appraisal pursuant to the DGCL, will automatically be canceled (subject to the appraisal rights of such holders) (such Common Shares, the “Dissenting Shares”); • each (i) Class A Share and (ii) Class A Share subject to a Director RSU Award (as defined below) that has fully vested as of the Effective Time, that is issued and outstanding immediately prior to the Effective Time and held by Parent or its affiliates, including the Specified Stockholders (which constitute Mr. Kemp, Dr. London and their immediate family members and certain trusts or other entities in which either Mr. Kemp or Dr. London or their immediate family members hold voting, proprietary, equity or other financial interests) and certain other holders of Class A Shares (the “Rollover Shares”), as of immediately prior to the Effective Time as a result of having been acquired by Parent or its affiliates pursuant to a rollover agreement in a form mutually acceptable to Parent and the Company (each, a “Rollover Agreement”) or in connection with the funding of a capital commitment set forth in an Equity Commitment Letter (as defined below), will be canceled and cease to exist (the “Rollover”); provided that the Rollover will be permitted only if no Class B Shares are issued and outstanding; • each Class A Share (other than (i) the Rollover Shares, (ii) any Canceled Common Shares and (iii) any applicable Dissenting Shares) issued and outstanding immediately prior to the Effective Time (such Class A Shares, the “Converted Shares”): o will automatically be canceled and converted into the right to receive $ 0.50 per share in cash, without interest (the “Merger Consideration”); o will no longer be outstanding and cease to exist; o each certificate formerly representing any such shares (each, a “Certificate”) or the applicable number of uncertificated shares represented by book-entry (each, a “Book-Entry Share”) will thereafter represent only the right to receive the Merger Consideration in accordance with the Merger Agreement; and • each share of common stock of Merger Sub (each, a “Merger Sub Share”) issued and outstanding immediately prior to the Effective Time will automatically be converted into and become one authorized, validly issued, fully paid and nonassessable share of common stock, par value $ 0.0001 per share, of the surviving corporation (each, a “Surviving Company Common Share”). Following the execution of the Merger Agreement, and pursuant to the terms of the Merger Agreement, the Company (i) deposited into a segregated bank account of Astra Space Operations LLC (the “Segregated Account”) an amount in cash equal to $ 3.5 million (the “Segregated Funds”).The Segregated Funds will be managed by the Company at the reasonable direction of the Special Committee of the Board of Directors acting in accordance with its fiduciary duties. All outstanding Convertible Notes will, immediately after the Merger becomes effective, be converted into shares of Series A preferred stock, par value $ 0.0001 per share, of Parent (the “Parent Series A Preferred Stock”) in accordance with a noteholder conversion agreement, by and among Parent, Merger Sub, and each holder of Convertible Notes (the “Noteholder Conversion Agreement”). The Original Warrants and Company Warrants will, immediately after the Merger becomes effective, be exchanged for warrants to purchase Parent Series A Preferred Stock in accordance with a warrant exchange agreement, by and among Parent, Merger Sub, and each holder of Company Warrants (the “Warrant Exchange Agreement”). Pursuant to the Merger Agreement, at the Effective Time, each outstanding option to purchase Class A Shares (each, a “Company Option”) other than a Company Option with an exercise price equal to or greater than the Merger Consideration (an “Underwater Option”), that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be assumed by Parent and converted into an option (the “Converted Options”) to purchase shares of class A common stock, par value $ 0.0001 per share, of Parent (the “Parent Class A Shares”). The Converted Options will continue to be subject to substantially the same terms and conditions as were applicable to such Company Options immediately prior to the Effective Time, except that (i) each Converted Option will be exercisable for that number of Parent Class A Shares equal to the number of Class A Shares subject to such option immediately prior to the Effective Time and (ii) the per share exercise price for each Parent Class A Share issuable upon exercise of a Converted Option will be equal to the exercise price per share of Class A Shares of such option immediately before the Effective Time. Each Underwater Option will be canceled for no consideration at the Effective Time. As of May 28, 2024, all Company Options were Underwater Options. In addition, at the Effective Time, each outstanding restricted stock unit with respect to Class A Shares (a “Company RSU Award” and collectively with the Company Options, the “Company Equity Awards”) held by any director of the Company who is not an employee of the Company (a “Director RSU Award”) will be accelerated in full. At the Effective Time, each Company RSU Award that has vested in accordance with its terms, or so accelerated in the case of Director RSU Awards (except for Rollover Shares that are issued upon acceleration of Director RSU Awards) will be canceled and will only entitle the holder of such Company RSU Award to receive (without interest) an amount in cash equal to (i) the number of Class A Shares subject to such Company RSU Award immediately prior to the Effective Time multiplied by (ii) the Merger Consideration. At the Effective Time, each Company RSU Award that has not vested in accordance with its terms or so accelerated will be canceled for no consideration. The execution and delivery of the Merger Agreement, subject to the requisite stockholder approval was recommended by the Special Committee to the Board on March 5, 2024. On March 5, 2024, the Board, with Mr. Kemp, Dr. London and Mr. Stanford abstaining, approved the execution and delivery of the Merger Agreement and recommended the adoption of the Merger Agreement and the Merger to the stockholders of the Company.

Liquidity	Liquidity The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these unaudited condensed consolidated financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of ASC Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these unaudited condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within the control of the Company as of the date the unaudited condensed consolidated financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the unaudited condensed consolidated financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern over the next twelve months through May 2025. Since inception, the Company has incurred significant operating losses and has an accumulated deficit of approximately $ 2.0 billion . As of March 31, 2024, the Company’s existing sources of liquidity included cash and cash equivalents of $ 6.6 million (including $ 3.5 million of funds that the Company may only use for specified purposes pursuant to the Merger Agreement) and restricted cash of $ 0.5 million. The restricted cash is related to a letter of credit issued to secure our performance obligations under a customer contract and is not accessible until we have begun delivery of flight sets for this customer's program which is expected to be in November 2024 pursuant to the contract schedule. The Company believes that its current level of cash and cash equivalents are not sufficient to fund commercial scale production and sale of its services and products. To proceed with the Company’s business plan and continue the Company's business operations, the Company will need to raise substantial additional funds through the issuance of additional debt, equity or both. Under the terms of the Merger Agreement, the Company is restricted from incurring new debt or issuing equity except through the offer and sale of the convertible notes due November 15, 2025 (the "Convertible Notes") and warrants to purchase shares of Class A Common Stock at an exercise price of $ 0.808 per share, in each case under the terms of the Subsequent Financing Agreement (as defined in Note 6). The term “Company Warrants” means and includes all warrants issued under the Subsequent Financing Agreement, together with warrants to purchase 1.5 million shares of Class A Common Stock issued on August 4, 2023. See Note 6 — Convertible Notes and Company Warrants. The Merger Agreement further prohibits the Company from issuing Convertible Notes or Company Warrants to any person prior to the consummation of the Merger unless (i) such person becomes a noteholder under the Noteholder Conversion Agreement, respectively, by executing a joinder agreement substantially in the form attached to such agreement and delivering the same to each of Merger Sub and Parent and (ii) holders of a majority in interest of the Convertible Notes or Warrants, as applicable, then outstanding consent to such issuance and joinder, all of which may affect the Company’s ability to raise additional funds from the sale of its Convertible Notes and Company Warrants on the timing needed. If the Company is unable to obtain sufficient financial resources, its business, financial condition and results of operations will be materially and adversely affected. The Company may be required to delay, limit, reduce or terminate its product development activities or future commercialization efforts or cease business operations, including through a petition for voluntary relief under Chapter 7 of the United States Bankruptcy Code (a “Chapter 7 Liquidation”). There can be no assurance that the Company will be able to obtain the needed financing on acceptable terms or on terms that would be permissible under the restrictions imposed by the Merger Agreement. As a result of these uncertainties, and notwithstanding management’s plans and efforts to date, there is substantial doubt about the Company’s ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. If the Company is unable to raise substantial additional capital in the near term and as necessary to continue the Company's operations prior to the closing of the Merger, the Company’s operations and production plans may be further scaled back or curtailed or cease entirely, and the Company may be required to furlough employees to manage its short term cash needs. Further, the Company may be required to file a Chapter 7 Liquidation and in such case, may not realize any significant value from its assets in connection with a liquidation. The Company has, however, prepared these unaudited condensed consolidated financial statements on a going concern basis, assuming that the Company's financial resources will be sufficient to meet its capital needs over the next twelve months. Accordingly, the Company's financial statements do not include adjustments relating to the recoverability and realization of assets and classification of liabilities that might be necessary should it be unable to continue in operation for the next twelve months.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company maintains cash and cash equivalent balances in bank accounts with multiple banking partners. All cash accounts are located in the United States (“U.S.”) and insured by the FDIC up to $ 250,000 . The Company's accounts receivables represent unconditional rights to consideration. The Company mitigates collection risks from its customers by performing regular credit evaluations of the Company's customers’ financial conditions. The Company believes there is no exposure to any significant credit risks related to its cash and cash equivalents or accounts receivable and has not experienced any losses in such accounts. The following customer's outstanding accounts receivable accounted for greater than 10% of the Company's trade accounts receivable as of the date reflected: March 31, 2024 December 31, 2023 Customer 1 88.9 % 92.4 % For the three months ended March 31, 2024 and 2023, one customer accounted for greater than 10% of the Company's total revenues: Three Months Ended 2024 2023 Customer 2 100.0 % —
Use of Estimates and Judgements	Use of Estimates and Judgments The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the unaudited condensed consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ significantly from those estimates. Significant items subject to such estimates and assumptions include the valuation of our Convertible Notes and Company Warrants and long-lived assets, inventory valuation and reserves, stock-based compensation, useful lives of intangible assets and property, plant and equipment, deferred tax assets, income tax uncertainties and other contingencies.
Significant Accounting Policies	Significant Accounting Policies There have been no changes to the Company’s significant accounting policies described in the Company’s 2023 Annual Report that have had a material impact on its unaudited condensed consolidated financial statements and related notes.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards There have been no new accounting standards applicable to the Company that have been adopted during the three months ended March 31, 2024. Recently Issued Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB") issued Accounting Standards Update (“ASU") 2023-09 (ASC Topic 740), Improvements to Income Tax Disclosures ("ASU 2023-09"). This ASU requires disaggregated income tax disclosures on the rate reconciliation and income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024 for publicly traded companies and December 15, 2025 for private companies. Early adoption is permitted for annual financial statements not yet issued or made available for issuance. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 updates reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance. ASU 2023-07 is effective for public companies for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures. In March 2024, the SEC adopted new rules that will require registrants to provide certain climate-related information in their registration statements and annual reports. The rules require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks will also include disclosure of a registrant's greenhouse gas emissions. In addition, the rules will require registrants to present certain climate-related financial metrics in their audited financial statements. The Company is currently evaluating the rules and the impact on its future consolidated statements. The Company also notes that on April 4, 2024, the SEC voluntarily stayed implementation of its recently adopted climate disclosure rules pending the outcome of certain legal challenges to the rules.

[1] The expected term is the length of time the grant is expected to be outstanding before it is exercised or terminated. This number is calculated as the midpoint between the vesting term and the original contractual term (contractual period to exercise). If the option contains graded vesting, then the vesting term would be based on the vesting pattern. Expected volatility, or the standard deviation of annualized returns, was calculated based on the Company's common stock price history for the expected term as of the valuation date. Risk-free interest was obtained from U.S. treasury notes for the expected terms noted as of the valuation date The Company has assumed a dividend yield of zero as it has no plans to declare dividends in the foreseeable future
