Item 8. Financial Statements and Supplementary Data Page Iridium Communications Inc.: Report of Ernst & Young LLP, Independent Registered Public Accounting Firm (PCAOB ID: 42 ) 54 Consolidated Balance Sheets 56 Consolidated Statements of Operations and Comprehensive Income (Loss) 57 Consolidated Statements of Changes in Stockholders’ Equity 58 Consolidated Statements of Cash Flows 59 Notes to Consolidated Financial Statements 60 53 Report of Ernst & Young LLP, Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of Iridium Communications Inc. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Iridium Communications Inc. (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations and comprehensive (income) loss, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2021 and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles. We also have 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, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 17, 2022 expressed an unqualified opinion thereon. 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 Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates. 54 Useful life of upgraded satellites Description of the Matter At December 31, 2021, the Company had $2.2 billion in Property and Equipment related to its upgraded satellites. As discussed in Note 2 to the consolidated financial statements, the Company’s upgraded satellites are depreciated on a straight-line basis over their estimated useful life, which is currently estimated to be 12.5 years. The Company’s useful life estimate is based on judgments made by management using the manufacturer’s estimated design life for the assets, engineering data relating to the operation and performance of its satellite network, and the Company’s long-term strategy for use of the assets. Auditing the Company's estimate of the useful life of the upgraded satellites involved a high degree of subjectivity due to the application of management’s judgment when evaluating the available information to determine the estimated useful life. The resulting estimated useful life has a significant effect on the timing of recognition of depreciation expense given the magnitude of the carrying amount of the upgraded satellites. How We Addressed the Matter in Our Audit We tested the design and operating effectiveness of controls over the Company's processes to determine the estimated useful life of its upgraded satellites, including controls over management's evaluation of the available information to determine the estimated useful life. To test the Company's estimated useful life of the upgraded satellites, our audit procedures included, among others, evaluating the application of available information to determine the estimated useful life of the upgraded satellites. For example, we compared management’s useful life estimate to the manufacturer’s estimated design life, publicly available information on the estimated useful life of similar assets, satellite operation and performance, and the life of its first-generation satellite constellation. Additionally, we evaluated the effect of changes, if any, in the Company’s long-term strategy for use of the assets on the useful life estimate. /s/ Ernst & Young LLP We have served as Company's auditor since 2001.

Notes to Consolidated Financial Statements December 31, 2021 1. Organization and Business Iridium Communications Inc. (the “Company”), a Delaware corporation, offers voice and data communications services and products to businesses, U.S. and international government agencies and other customers on a global basis. The Company is a provider of mobile voice and data communications services via a constellation of low earth orbiting satellites. The Company holds various licenses and authorizations from the U.S. Federal Communications Commission (the “FCC”) and from foreign regulatory bodies that permit the Company to conduct its business, including the operation of its satellite constellation. The Company’s operations are conducted through, and its operating assets are owned by, its principal operating subsidiary, Iridium Satellite LLC (“Iridium Satellite”), Iridium Satellite’s immediate parent, Iridium Holdings LLC, and their subsidiaries. As a result, there are no material differences between the information presented in these consolidated financial statements of the Company and the financial information of Iridium Holdings, Iridium Satellite and their subsidiaries, on a consolidated basis, other than as a result of (i) tax provision as a result of Iridium Holdings, Iridium Satellite and their subsidiaries being classified as flow-through entities for U.S. federal income tax purposes and (ii) senior unsecured notes (fully repaid February 15, 2020, see Note 7 ), related interest expense and loss on extinguishment of debt. 2. Significant Accounting Policies and Basis of Presentation Principles of Consolidation and Basis of Presentation The Company has prepared the consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The accompanying consolidated financial statements include the accounts of (i) the Company, (ii) its wholly owned subsidiaries, and (iii) all less than wholly owned subsidiaries that the Company controls. All material intercompany transactions and balances have been eliminated. 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 disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, the useful lives and recoverability of long-lived and intangible assets, income taxes, stock-based compensation, the incremental borrowing rate for its leases, and contingencies, among others. The Company bases these estimates on historical and anticipated results, trends, and various other assumptions that it believes are reasonable, including assumptions as to future events. These estimates form the basis for making judgments about the carrying values of assets and liabilities and recorded revenues and expenses. Actual results could differ materially from those estimates. Adopted and Recently Issued Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). This guidance amends certain aspects of the accounting for income taxes. The Company's adoption of ASU 2019-12 on January 1, 2021 had no impact on its consolidated financial statements and related disclosures. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The guidance provides optional expedients and exceptions for contracts, hedging relationships, and other transactions that reference London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. ASU 2020-04 was further amended in January 2021 when the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”), which clarified the applicability of certain provisions. Both ASU 2020-04 and ASU 2021-01 are currently effective prospectively for all entities through December 31, 2022 when the reference rate replacement activity is expected to have been completed. The guidance in ASU 2020-04 and ASU 2021-01 is optional and may be elected over time as reference rate reform activities occur. As of December 31, 2021 , the Company elected to apply the optional expedient for hedge accounting specifically to the interest rate cap agreement (the "Cap") which was executed in July 2021. This allowed the Company to assume that the index upon which future interest payments on the hedged portion of the Term Loan (see Note 8 ) will be based matches the index on the Cap. Adoption of this 60 practical expedient had no impact on the Company's consolidated financial statements upon adoption. The Company has not yet adopted any other expedients and will continue to evaluate the impact this standard may have on its consolidated financial statements. Fair Value Measurements The Company evaluates assets and liabilities subject to fair value measurements on a recurring and non-recurring basis to determine the appropriate level to classify them for each reporting period. This determination requires significant judgments to be made by management of the Company. Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. U.S. GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of observability of inputs used in measuring fair value. The fair value hierarchy consists of the following tiers: • Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair value estimates are based upon certain market assumptions and information available to the Company. The carrying values of the following financial instruments approximated their fair values as of December 31, 2021 and 2020: cash and cash equivalents, prepaid expenses and other current assets, accounts receivable, accounts payable, and accrued expenses and other current liabilities. Fair values approximate their carrying values because of their short-term nature. The Level 2 cash equivalents include money market funds, commercial paper and short-term U.S. agency securities. The Company also classifies its derivative financial instruments as Level 2. The fair values of the Company’s Level 2 estimates are based upon certain market assumptions and information available to the Company. In determining fair value, the Company uses a market approach utilizing valuation models that incorporate observable inputs such as interest rates, bond yields and quoted prices for similar assets. Leases For new leases, the Company will determine if an arrangement is or contains a lease at inception. Leases are included as right-of-use (“ROU”) assets within other assets and ROU liabilities within accrued expenses and other liabilities and within other long-term liabilities on the Company’s consolidated balance sheets. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Certain leases contain variable contractual obligations as a result of future base rate escalations which are estimated based on observed trends and included within the measurement of present value. The Company’s leases do not provide an implicit rate. The Company uses its 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 payments made and excludes lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For certain leases, such as teleport network facilities, the Company elected the practical expedient to combine lease and non-lease components as a single lease component. Taxes assessed on leases in which the Company is either a lessor or lessee are excluded from contract consideration and variable payments when measuring new lease contracts or remeasuring existing lease contracts. 61 Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and receivables. The majority of cash is invested into a money market fund with U.S. treasuries, Agency Mortgage Backed Securities and/or U.S. government guaranteed debt. While the Company maintains its cash and cash equivalents with financial institutions with high credit ratings, it often maintains those deposits in federally insured financial institutions in excess of federally insured limits. The Company performs credit evaluations of its customers’ financial condition and records reserves to provide for estimated credit losses. Accounts receivable are due from both domestic and international customers. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of ninety days or less to be cash equivalents. These investments, along with cash deposited in institutional money market funds, regular interest bearing depository accounts and non-interest bearing depository accounts, are classified as cash and cash equivalents on the accompanying consolidated balance sheets. Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and are subject to late fee penalties. Management develops its estimate of an allowance for uncollectible receivables based on the Company’s experience with specific customers, aging of outstanding invoices, its understanding of customers’ current economic circumstances and its own judgment as to the likelihood that the Company will ultimately receive payment. The Company writes off its accounts receivable when balances ultimately are deemed uncollectible. The allowance for doubtful accounts was not material as of December 31, 2021 and 2020. Foreign Currencies Generally, the functional currency of the Company’s foreign consolidated subsidiaries is the local currency. Assets and liabilities of its foreign subsidiaries are translated to U.S. dollars based on exchange rates at the end of the reporting period. Income and expense items are translated at the weighted-average exchange rates prevailing during the reporting period. Translation adjustments are accumulated in a separate component of stockholders’ equity. Transaction gains or losses are classified as other income (expense), net in the accompanying consolidated statements of operations and comprehensive income (loss). In instances where the financial statements of a foreign entity in a highly inflationary economy are material, they are remeasured as if the functional currency were the reporting currency. In these instances, the financial statements of those entities are remeasured into the reporting currency. A highly inflationary economy is one that has cumulative inflation of approximately 100 % or more over a three-year period. Deferred Financing Costs Direct and incremental costs incurred in connection with securing debt financing are deferred and are amortized as additional interest expense using the effective interest method over the term of the related debt. Capitalized Interest During the development and construction periods of a project, including the financing of the Company's upgraded satellite constellation, the Company capitalizes interest. Capitalization ceases when the asset is ready for its intended use or when these activities are substantially suspended. If some portions of a project are substantially complete and ready for use and other portions have not yet reached that stage, the Company ceases capitalizing costs on the completed portion of the project but continues to capitalize for the incomplete portion of the project. Inventory Inventory consists primarily of finished goods, although the Company at times also maintains an inventory of raw materials from third-party manufacturers. The Company outsources manufacturing of subscriber equipment to a third-party manufacturer and purchases accessories from third-party suppliers. The Company’s cost of inventory includes an allocation of overhead, including payroll and payroll-related costs of employees directly involved in bringing inventory to its existing condition, and freight. Inventories are valued using the average cost method and are carried at the lower of cost or net realizable value. The Company's expense for excess and obsolete inventory was not material during the years ended December 31, 2021, 2020 or 2019. 62 The Company has a manufacturing agreement with Benchmark Electronics Inc. (“Benchmark”) to manufacture most of its subscriber equipment. Pursuant to the agreement, the Company may be required to purchase excess materials at cost plus a contractual markup if the materials are not used in production within the periods specified in the agreement. Benchmark will then repurchase such materials from the Company at the same price paid by the Company, as required for the production of the subscriber equipment. The Company's inventory balance consisted of the following: Year Ended December 31, 2021 2020 (In thousands) Finished Goods $ 18,395 $ 27,936 Raw Materials 11,850 5,983 Inventory Valuation Reserve ( 1,201 ) ( 1,439 ) Total $ 29,044 $ 32,480 Stock-Based Compensation The Company accounts for stock-based compensation at fair value. The fair value of stock options is determined at the grant date using the Black-Scholes-Merton option pricing model. The fair value of restricted stock units (“RSUs”) is equal to the closing price of the underlying common stock on the grant date. The fair value of an award that is ultimately expected to vest is recognized on a straight-line basis over the requisite service or performance period and is classified in the consolidated statements of operations and comprehensive income (loss) in a manner consistent with the classification of the recipient’s compensation. The expected vesting of the Company’s performance-based RSUs is based upon the probability that the Company achieves the defined performance goals. The level of achievement of performance goals, if any, is determined by the Compensation Committee. Stock-based awards to non-employee consultants are expensed at their grant-date fair value as services are provided according to the terms of their agreements and are classified in selling, general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss). Classification of stock-based compensation by line item on the balance sheet and statement of operations is presented below: Year Ended December 31, 2021 2020 (In thousands) Property and equipment, net $ 2,376 $ 1,319 Inventory 436 261 Prepaid and other current assets 22 28 Cost of subscriber equipment 53 29 Cost of services (exclusive of depreciation and amortization) 8,037 5,037 Research and development 333 305 Selling, general and administrative 18,359 11,343 Total stock-based compensation $ 29,616 $ 18,322 63 Property and Equipment Property and equipment is carried at cost less accumulated depreciation. The Company applies judgment in determining the useful lives based on factors such as engineering data, long-term strategy for using the assets, the manufacturer's estimated design life for the assets, laws and regulations that could impact the useful lives of the assets and other economic factors. The Company assesses the current estimated operational life of the satellites, including the potential impact of environmental factors on the satellites, ongoing operational enhancements and software upgrades when evaluating the useful lives of its satellites. Additionally, the Company reviews engineering data relating to the operation and performance of its satellite network. Depreciation is calculated using the straight-line method over the following estimated useful lives: Satellites 12.5 years Ground system 5-7 years Equipment 3-5 years Internally developed software and purchased software 3-7 years Building 39 years Building improvements 5-39 years Leasehold improvements shorter of useful life or remaining lease term The Company calculates depreciation expense using the straight-line method and evaluates the appropriateness of the useful life used in this calculation on a quarterly basis or as events occur that require additional assessment. Repairs and maintenance costs are expensed as incurred. Derivative Financial Instruments The Company uses derivatives (interest rate swap, swaption, cap) to manage its exposure to fluctuating interest rate risk on variable rate debt. Its derivatives are measured at fair value and are recorded on the consolidated balance sheets within other current liabilities and other assets. When the Company’s derivatives are designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives are recorded in accumulated other comprehensive income (loss) within the Company’s consolidated balance sheets and subsequently recognized in earnings when the hedged items impact earnings. Any ineffective portion of a derivative's change in fair value will be recognized in earnings in the same period in which the hedged interest payments affect earnings. Within the consolidated statements of operations and comprehensive income (loss), the gains and losses related to cash flow hedges are recognized within interest income (expense), net, as this is the same financial statement line item associated with the hedged items. Cash flows from hedging activities are included in operating activities within the Company’s consolidated statements of cash flows, which is the same category as the item being hedged. See Note 8 for further information. Long-Lived Assets The Company assesses its long-lived assets for impairment when indicators of impairment exist. Recoverability of assets is measured by comparing the carrying amounts of the assets to the future undiscounted cash flows expected to be generated by the assets. Any impairment loss would be measured as the excess of the assets’ carrying amount over their fair value. Intangible Assets The Company’s intangible assets with finite lives are amortized over their useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If any indicators were present, the Company would test for recoverability by comparing the carrying amount of the asset to the net undiscounted cash flows expected to be generated from the asset. If those net undiscounted cash flows do not exceed the carrying amount (i.e., the asset is not recoverable), the Company would perform the next step, which is to determine the fair value of the asset and record an impairment loss, if any. The Company evaluates the useful lives for these intangible assets each reporting period to determine whether events and circumstances warrant a revision in their remaining useful lives. 64 Amortization is calculated using the straight-line method over the following estimated useful lives: Intellectual property 20 years Assembled workforce 7 years Patents 14 - 20 years Revenue Recognition The Company derives its revenue primarily as a wholesaler of satellite communications products and services. The primary types of revenue include (i) service revenue (access and usage-based airtime fees), (ii) subscriber equipment revenue, and (iii) revenue generated by providing engineering and support services to commercial and government customers. In addition to the discussion immediately below, see Note 12 for further discussion of the Company's revenue recognition. Wholesaler of satellite communications products and services Pursuant to wholesale agreements, the Company sells its products and services to service providers and recognizes revenue as it fulfills its performance obligations to the service providers, based an amount that reflects the consideration to which it expects to be entitled to in exchange for those products and services. The service providers, in turn, sell the products and services to other distributors or directly to the end users. The Company recognizes revenue when an arrangement exists, services or equipment are transferred, the transaction price is determined, the arrangement has commercial substance, and collection of consideration is probable. Contracts with multiple performance obligations At times, the Company sells services and equipment through arrangements that bundle equipment, airtime and other services. For these revenue arrangements when the Company sells services and equipment in bundled arrangements and determines that it has separate distinct performance obligations, the Company allocates the bundled contract price among the various performance obligations based on each deliverable’s stand-alone selling price. If the stand-alone selling price is not directly observable, the Company estimates the amount to be allocated for each performance obligation based on observable market transactions or the residual approach. When the Company determines the performance obligations are not distinct, the Company recognizes revenue on a combined basis. To the extent the Company's contracts include variable consideration, the transaction price includes both fixed and variable consideration. The variable consideration contained within the Company's contracts with customers may include discounts, credits and other similar items. When a contract includes variable consideration, the Company evaluates the estimate of the variable consideration to determine whether the estimate needs to be constrained; therefore, the Company includes the variable consideration in the transaction price only to the extent that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration estimates are updated at the end of each quarter. Service revenue sold on a stand-alone basis Service revenue is generated from the Company’s service providers through usage of its satellite system and through fixed monthly access fees per user charged to service providers. Revenue for usage is recognized when usage occurs and billed in arrears with payments generally submitted within 30 days. Revenue for fixed-per-user access fees is billed monthly in advance and generally recognized over the month, or related usage period, in which the services are provided to the end user. The Company sells prepaid services in the form of e-vouchers and prepaid cards. A liability is established equal to the cash paid upon purchase for the e-voucher or prepaid card. The Company recognizes revenue from (i) the prepaid services upon the use of the e-voucher or prepaid card by the customer and (ii) the estimated pattern of use. The Company does not offer refunds for unused prepaid services. Services sold to the U.S. government The Company provides airtime and airtime support to U.S. government and other authorized customers pursuant to the Enhanced Mobile Satellite Services (“EMSS”) contract managed by the U.S. Space Force. Under the terms of this agreement, authorized customers continue to utilize airtime services, provided through the U.S. government’s dedicated gateway. These services include unlimited global standard and secure voice, low and high-speed data, paging, broadcast and Distributed Tactical Communications Services (“DTCS”) services for an unlimited number of Department of Defense (“DoD”) and other federal subscribers. Under this contract, revenue is based on the annual fee for the fixed-price contract with unlimited 65 subscribers and is recognized on a straight-line basis over each contractual year, with equal payments submitted monthly. The U.S. government purchases its subscriber equipment from third-party distributors and not directly from the Company. Subscriber equipment sold on a stand-alone basis The Company recognizes subscriber equipment sales and the related costs when title to the equipment (and the risks and rewards of ownership) passes to the customer, typically upon shipment. Customers are billed when inventory is shipped, and payment is generally due within 30 days. Customers do not have rights of return without prior consent from the Company. Government engineering and support services The Company provides maintenance services to the U.S. government’s dedicated gateway. This revenue is recognized ratably over the periods in which the services are provided; the related costs are expensed as incurred. Other government and commercial engineering and support services The Company also provides engineering services to assist customers in developing new technologies for use on the Company’s satellite system. Fees to customers under these agreements are generally based on milestones and payments are submitted as milestones are achieved. The revenue associated with fixed-fee contracts is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying its performance obligation. The Company does not include purchases of goods from a third party in its evaluation of costs incurred. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. The revenue associated with cost-plus-fixed-fee contracts is recognized to the extent of estimated costs incurred plus the applicable fees earned. The Company considers fixed fees under cost-plus-fixed-fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract. Research and Development Research and development costs are charged to expense in the period in which they are incurred. Advertising Costs Costs associated with advertising and promotions are expensed as incurred. Advertising expenses were $ 1.9 million, $ 1.2 million and $ 0.9 million for the years ended December 31, 2021, 2020 and 2019, respectively. Income Taxes The Company accounts for income taxes using the asset and liability approach, which requires the recognition of tax benefits or expenses for temporary differences between the financial reporting and tax bases of assets and liabilities. A valuation allowance is established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company also recognizes a tax benefit from uncertain tax positions only if it is “more likely than not” that the position is sustainable based on its technical merits. The Company’s policy is to recognize interest and penalties on uncertain tax positions as a component of income tax expense. Net Loss Per Share The Company calculates basic net loss per share by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share takes into account the effect of potentially dilutive common shares when the effect is dilutive. The effect of potentially dilutive common shares, including common stock issuable upon exercise of outstanding stock options, is computed using the treasury stock method. The effect of potentially dilutive common shares from the conversion of outstanding convertible preferred securities was computed using the as-if converted method at the stated conversion rate. The Company’s unvested RSUs awarded to the board of directors contain non-forfeitable rights to dividends and therefore are considered to be participating securities in periods of net income. The calculation of basic and diluted net loss per share excludes net income attributable to these unvested RSUs from the numerator and excludes the impact of these unvested RSUs from the denominator. 66 3. Cash and Cash Equivalents and Marketable Securities Cash and Cash Equivalents The following table summarizes the Company’s cash and cash equivalents: December 31, Recurring Fair Value Measurement 2021 2020 (In thousands) Cash and cash equivalents: Cash $ 28,496 $ 27,168 Money market funds 292,417 208,005 Level 2 Fixed income debt securities — 2,005 Level 2 Total cash and cash equivalents $ 320,913 $ 237,178 Marketable Securities As of December 31, 2021, the Company did not hold any investment positions in marketable securities. As of December 31, 2020, the Company's marketable securities consisted of only fixed-income securities. The amortized cost of these securities amounted to $ 7.6 million and the estimated fair value amounted to $ 7.5 million as of December 31, 2020. The gross unrealized gains and gross unrealized losses on these marketable securities were not material as of December 31, 2020. All marketable securities were classified as Level 2 investments in the fair value hierarchy.

Future amortization expense with respect to intangible assets existing at December 31, 2021, by year and in the aggregate, was as follows: Year ending December 31, Amount (In thousands) 2022 $ 1,555 2023 1,555 2024 744 2025 744 2026 744 Thereafter 3,432 Total estimated future amortization expense $ 8,774 69 6. Leases The Company has operating leases for land, office space, satellite network operations center (“SNOC”) facilities, system gateway facilities, a warehouse and a distribution center. The Company also has operations and maintenance (“O&M”) agreements that include leases associated with two teleport network facilities. Some of the Company's leases include options to extend the leases for up to 10 years. The Company does not include term extension options as part of its present value calculation of lease liabilities unless it is reasonably certain to exercise those options. As of December 31, 2021, the Company’s weighted-average remaining lease term relating to its operating leases was 5.9 years, and the weighted-average discount rate used to calculate the operating lease liability payment was 6.7 %. The table below summarizes the Company’s lease-related assets and liabilities: Leases Classification December 31, 2021 December 31, 2020 (In thousands) Operating lease assets Noncurrent Other assets $ 20,369 $ 23,974 Total lease assets $ 20,369 $ 23,974 Operating lease liabilities Current Accrued expenses and other current liabilities $ 3,703 $ 3,838 Noncurrent Other long-term liabilities 19,587 23,258 Total lease liabilities $ 23,290 $ 27,096 During the years ended December 31, 2021, 2020 and 2019, the Company incurred lease expense of $ 5.6 million, $ 5.6 million and $ 5.1 million, respectively. A portion of rent expense during these comparable periods was derived from leases that were not included within the ROU asset and liability balances shown above as they had terms shorter than twelve months and were therefore excluded from balance sheet recognition under ASU 2016-02. Future payment obligations with respect to the Company's operating leases in which it was the lessee at December 31, 2021, by year and in the aggregate, were as follows: Year Ending December 31, Amount (In thousands) 2022 $ 5,270 2023 4,997 2024 4,972 2025 5,088 2026 3,287 Thereafter 4,921 Total lease payments $ 28,535 Lessor Arrangements Operating leases in which the Company is a lessor consist primarily of hosting agreements with Aireon LLC (“Aireon”) (see Note 14 ) and L3Harris Technologies, Inc. (“L3Harris”) for space on the Company’s satellites. These agreements provide for a fee that will be recognized over the life of the satellites, currently estimated to be approximately 12.5 years. Lease income related to these agreements was $ 21.4 million, $ 21.4 million and $ 21.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. Lease income is recorded as hosted payload and other data service revenue within service revenue on the Company’s consolidated statements of operations and comprehensive income (loss). 70 Both Aireon and L3Harris have made payments for their hosting agreements and the Company expects they will continue to do so. Future income with respect to the Company's operating leases in which it was the lessor at December 31, 2021, by year and in the aggregate, is as follows: Year Ending December 31, Amount (In thousands) 2022 $ 21,445 2023 21,445 2024 21,445 2025 21,445 2026 21,445 Thereafter 77,462 Total lease income $ 184,687 7. Debt Term Loan and Revolving Facility On November 4, 2019, pursuant to a loan agreement (as amended to date, the “Credit Agreement”), the Company entered into a $ 1,450.0 million term loan with Deutsche Bank AG (the “Original Term Loan”) and an accompanying $ 100.0 million revolving loan (the “Revolving Facility”). The Original Term Loan was issued at a price equal to 99.5 % of its face value, with a maturity date in November 2026. On February 7, 2020, the Company closed on an additional $ 200.0 million under its Credit Agreement for a total borrowing of $ 1,650.0 million (as expanded, the “Term Loan”). The additional amount is fungible with the Original Term Loan, having the same maturity date, interest rate and other terms, but was issued at a 1.0 % premium to face value. The Term Loan initially bore interest at an annual rate of LIBOR plus 3.75 %, with a 1.0 % LIBOR floor. The Term Loan was repriced in January 2021 for an annual interest rate of LIBOR plus 2.75 %, with a 1.0 % LIBOR floor. The Term Loan was repriced again in July 2021 for a new annual interest rate of LIBOR plus 2.50 %, with a 0.75 % LIBOR floor. The maturity date remains unchanged in November 2026. The interest rate on the Revolving Facility remained unchanged at LIBOR plus 3.75 % with no LIBOR floor, and a maturity date in November 2024. Principal payments, which are payable quarterly and began on June 30, 2020, equal $ 16.5 million per annum (one percent of the full principal amount of the Term Loan), with the remaining principal due upon maturity. In July 2021, the Company paid $ 4.1 million of original issuance costs to reprice the Term Loan. Lenders making up approximately $ 65.2 million of the Term Loan did not participate in the repricing. Those portions of the Term Loan were replaced by new or existing lenders. This resulted in a $ 0.9 million loss on extinguishment of debt during the year ended December 31, 2021, as the Company wrote off the unamortized debt issuance costs related to the lenders who were fully repaid in an exchange of principal. In February 2020, the Company used the proceeds of the additional $ 200.0 million borrowed under the Term Loan, together with cash on hand, to prepay and retire all of the indebtedness outstanding under then outstanding senior unsecured promissory notes (the “Notes”), including premiums for early prepayment. To prepay the Notes, the Company paid a call price equal to the present value at the redemption rate of (i) 105.125 % of the $ 360.0 million principal amount of the Notes plus (ii) all interest due through the first call date in April 2020, representing a total call premium of $ 23.5 million, plus all accrued and unpaid interest to the redemption date. As a result of the prepayment, the Company also wrote off the remaining unamortized debt issuance costs, which resulted in a $ 30.2 million loss on extinguishment of debt during the year ended December 31, 2020. As of December 31, 2021 and 2020, the Company reported an aggregate of $ 1,621.1 million and $ 1,637.6 million in borrowings under the Term Loan, respectively. These amounts do not include $ 23.1 million and $ 24.0 million of net unamortized deferred financing costs as of December 31, 2021 and 2020, respectively. The net principal balance in borrowings in the accompanying consolidated balance sheets as of December 31, 2021 and 2020 amounted to $ 1,598.0 million and $ 1,613.6 million, respectively. As of December 31, 2021 and 2020, based upon over-the-counter bid levels (Level 2 - market approach), the fair value of the borrowings under the Term Loan due in 2026 was $ 1,622.1 million and $ 1,647.9 million, respectively. The Company had not borrowed under the Revolving Facility as of December 31, 2021 or 2020. The Credit Agreement restricts the Company’s ability to incur liens, engage in mergers or asset sales, pay dividends, repay subordinated indebtedness, incur indebtedness, make investments and loans, and engage in other transactions as specified in the Credit Agreement. The Credit Agreement provides for specified exceptions, including baskets measured as a percentage of 71 trailing twelve months of earnings before interest, taxes, depreciation and amortization (“EBITDA”) and unlimited exceptions based on achievement and maintenance of specified leverage ratios, for, among other things, incurring indebtedness and liens and making investments, restricted payments for dividends and share repurchases, and payments of subordinated indebtedness. The Credit Agreement also contains a mandatory prepayment sweep mechanism with respect to a portion of the Company’s excess cash flow (as defined in the Credit Agreement), which is phased out based on achievement and maintenance of specified leverage ratios. As of December 31, 2021, the Company was below the specified leverage ratio and a mandatory prepayment sweep was therefore not required. The Credit Agreement contains no financial maintenance covenants with respect to the Term Loan. With respect to the Revolving Facility, the Credit Agreement requires the Company to maintain a consolidated first lien net leverage ratio (as defined in the Credit Agreement) of no greater than 6.25 to 1 if more than 35 % of the Revolving Facility has been drawn. The Credit Agreement contains other customary representations and warranties, affirmative and negative covenants, and events of default. The Company was in compliance with all covenants as of December 31, 2021. The effective interest rate on outstanding principal of the Term Loan was 4.3 % during the year ended December 31, 2021. Interest on Debt Total interest incurred includes amortization of deferred financing fees and capitalized interest. To reprice the Term Loan in January 2021 and July 2021, the Company incurred third-party financing costs of $ 3.6 million and $ 1.3 million, respectively. These costs were expensed and are included within interest expense on the consolidated statements of operations and comprehensive income (loss) for the year ended December 31, 2021. All third-party financing costs incurred during the years ended December 31, 2020 and 2019 were also expensed and are included within interest expense on the consolidated statements of operations and comprehensive income (loss). The following table presents the interest and amortization of deferred financing fees related to the Term Loan: Year Ended December 31, 2021 2020 2019 (In thousands) Total interest incurred $ 72,816 $ 99,155 $ 140,532 Amortization of deferred financing fees $ 4,316 $ 3,773 $ 21,320 Capitalized interest $ 2,146 $ 3,225 $ 15,055 As of December 31, 2021 and 2020, accrued interest under the Term Loan was $ 0.1 million and $ 0.2 million, respectively. Total Debt Future minimum principal repayments with respect to the Company's debt balances existing at December 31, 2021, by year and in the aggregate, are as follows: Year ending December 31, Amount (In thousands) 2022 $ 16,500 2023 16,500 2024 16,500 2025 16,500 2026 1,555,125 Total debt commitments 1,621,125 Less: Original issuance discount 23,109 Less: Total short-term debt 16,500 Total long-term debt, net $ 1,581,516 72 The repayment schedule above excludes future amounts that may be required to be prepaid pursuant to the excess cash flow sweep provision of the Credit Agreement, as those amounts are not determinable in advance. 8. Derivative Financial Instruments The Company is exposed to interest rate fluctuations related to its Term Loan. The Company has reduced its exposure to fluctuations in the cash flows associated with changes in the variable interest rate by entering into offsetting positions through the use of interest rate swap and interest rate cap contracts which result in recognizing a fixed interest rate for a portion of the Term Loan. This will reduce the negative impact of increases in the variable rate over the term of the derivative contracts. These contracts are not used for trading or other speculative purposes. Historically, the Company has not incurred, and does not expect to incur in the future, any losses as a result of counterparty default. Hedge effectiveness of interest rate swap and cap contracts is based on a long-haul hypothetical derivative methodology and includes all changes in value. The Company formally assesses, both at the hedge’s inception and on an ongoing quarterly basis, whether the designated derivative instruments are highly effective in offsetting changes in the cash flows of the hedged items. When the hedging instrument is sold, expires, is terminated, is exercised, no longer qualifies for hedge accounting, is de-designated, or is no longer probable, hedge accounting is discontinued prospectively. Interest Rate Swaps On November 27, 2019, the Company executed a long-term interest rate swap (“Swap”) through November 2021 to mitigate variability in forecasted interest payments on a portion of the Company’s borrowings under its Term Loan. On the last business day of each month, the Company received variable interest payments based on one-month LIBOR from the counterparty. The Company paid a fixed rate of 1.565 % per annum on the Swap until its expiration in November 2021. The Company also entered into an interest rate swaption agreement (“Swaption”), for which the Company paid a fixed annual rate of 0.50 %. At inception, the Swap and Swaption (collectively, the "swap contracts") were designated as cash flow hedges for hedge accounting. The unrealized changes in market value were recorded in accumulated other comprehensive income (loss) and any remaining balance will be reclassified into earnings during the period in which the hedged transaction affects earnings. Due to the changes made to the Term Loan as a result of the July 2021 repricing, at that time the Company elected to de-designate the Swap as a cash flow hedge. Accordingly, as the related interest payments were still probable, the accumulated balance within other comprehensive income (loss) as of the de-designation date was amortized into earnings through the November 2021 expiration date. As of December 31, 2020, the Swap carried a notional amount of $ 1.0 billion and had a current liability balance of $ 5.2 million in other current liabilities related to the fair value of the Swap. The Swaption carried a notional amount of $ 1.0 billion as of December 31, 2020. At December 31, 2020, the premium liability was netted with the Swaption, for a fair value of $ 4.4 million which was recorded in other current liabilities. The Company sold the Swaption in May 2021 for $ 0.7 million. The Company continued to pay the fixed annual rate for the Swaption through the term of the Swaption, which expired in November 2021. Interest Rate Cap On July 21, 2021, the Company entered into the Cap that began in December 2021 upon the expiration of the Swap. The Cap manages the Company's exposure to interest rate movements on a portion of the Term Loan from the Cap's inception through the maturity of the Term Loan in November 2026. The Cap provides the Company with the right to receive payment if one-month LIBOR exceeds 1.5 %. Beginning in December 2021, the Company began to pay a fixed monthly premium based on an annual rate of 0.31 % for the Cap. The Cap carried a notional amount of $ 1.0 billion as of December 31, 2021. The Cap is designed to mirror the terms of the Term Loan and to offset the cash flows being hedged. The Company designated the Cap as a cash flow hedge of the variability of the LIBOR-based interest payments on the Term Loan. The effective portion of the Cap's change in fair value will be recorded in accumulated other comprehensive income (loss). Any ineffective portion of the Cap's change in fair value will be recorded in current earnings as interest expense. 73 Fair Value of Derivative Instruments As of December 31, 2021, the Company had an asset balance of $ 4.9 million recorded in other assets for the fair value of the Cap. During the years ended December 31, 2021, 2020, and 2019 the Company collectively incurred $ 8.5 million, $ 9.1 million, and $ 0.3 million, respectively, in net interest expense for the swap contracts and the Cap. Gains and losses resulting from fair value adjustments to the Cap are recorded within accumulated other comprehensive income (loss) within the Company’s consolidated balance sheet and reclassified to interest expense on the dates that interest payments become due. Cash flows related to the derivative contracts are included in cash flows from operating activities on the consolidated statements of cash flows. Over the next 12 months, the Company expects any gains or losses for cash flow hedges amortized from accumulated other comprehensive income (loss) into earnings to have an immaterial impact on the Company’s consolidated financial statements. The following table presents the amount of unrealized gain or loss and related tax impact associated with the derivative instruments that the Company recorded in its consolidated statements of operations and comprehensive income (loss): Year Ended December 31, 2021 2020 2019 (In thousands) Unrealized gain (loss), net of tax $ 10,408 $ ( 7,036 ) $ ( 121 ) Tax benefit (expense) $ ( 3,316 ) $ 2,464 $ ( 41 ) 9. Stock-Based Compensation In May 2019, the Company’s stockholders approved the amendment and restatement of the Company’s 2015 Equity Incentive Plan (as so amended and restated, the “Amended 2015 Plan”). As of December 31, 2021, the remaining aggregate number of shares of the Company’s common stock available for future grants under the Amended 2015 Plan was 10,462,457 . The Amended 2015 Plan provides for the grant of stock-based awards, including nonqualified stock options, incentive stock options, restricted stock, restricted stock units (“RSUs”), stock appreciation rights and other equity securities to employees, consultants and non-employee directors of the Company and its affiliated entities. The number of shares of common stock available for issuance under the Amended 2015 Plan is reduced by (i) one share for each share of common stock issued pursuant to an appreciation award, such as a stock option or stock appreciation right with an exercise or strike price of at least 100 % of the fair market value of the underlying common stock on the date of grant, and (ii) 1.8 shares for each share of common stock issued pursuant to any stock award that is not an appreciation award, also referred to as a “full value award.” The Amended 2015 Plan allows the Company to utilize a broad array of equity incentives and performance cash incentives in order to secure and retain the services of its employees, directors and consultants, and to provide long-term incentives that align the interests of its employees, directors and consultants with the interests of the Company’s stockholders. The Company accounts for stock-based compensation at fair value. Stock Options The stock option awards granted to employees generally (i) have a term of ten years , (ii) vest over four years with 25 % vesting after the first year of service and the remainder vesting ratably on a quarterly basis thereafter, (iii) are contingent upon employment on the vesting date, and (iv) have an exercise price equal to the fair market value of the underlying shares at the date of grant. 74 The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of its stock option awards on the date of grant. The Company will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model. The Black-Scholes-Merton option pricing model incorporates the following assumptions: • Volatility - The expected volatility of the options granted was estimated based upon historical volatility of the Company's share price of its common stock through daily observations of its trading history. • Expected life of options - The expected life of options granted to employees was determined from the simplified method. • Risk-free interest rate - The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants. • Dividend yield - The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. The Company does not anticipate paying dividends during the expected term of the grants; therefore, the dividend rate is assumed to be zero. The Company has historically granted stock options to newly hired and promoted employees. During 2019, the Company granted approximately 139,000 stock options with an estimated aggregate grant date fair value of $ 1.3 million. The Company did not grant any stock options during the years ended December 31, 2021 and 2020. The following table summarizes weighted-average assumptions used in the Company's calculations of fair value: Year Ended December 31, 2019 Expected volatility 40.78 % Expected term (years) 6.11 Expected dividends — % Risk free interest rate 2.59 % 75 A summary of the activity of the Company’s stock options is as follows: Shares Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (In thousands, except years and per share data) Options outstanding at December 31, 2018 5,703 $ 8.29 Granted 139 21.12 Cancelled or expired ( 1 ) 11.80 Exercised ( 1,670 ) 8.11 $ 29,584 Forfeited ( 18 ) 11.74 Options outstanding at December 31, 2019 4,153 $ 8.78 4.03 $ 65,887 Cancelled or expired ( 5 ) 20.17 Exercised ( 1,581 ) 8.14 $ 33,836 Forfeited ( 13 ) 18.17 Options outstanding at December 31, 2020 2,554 $ 9.10 3.94 $ 77,182 Cancelled or expired ( 3 ) 10.67 Exercised ( 857 ) 8.51 $ 31,544 Forfeited ( 13 ) 16.07 Options outstanding at December 31, 2021 1,681 $ 9.35 3.28 $ 53,698 Options exercisable at December 31, 2021 1,603 $ 8.84 3.11 $ 52,021 Options exercisable and expected to vest at December 31, 2021 1,680 $ 9.34 3.28 $ 53,684 The Company recognized $ 0.8 million, $ 1.0 million and $ 1.3 million of stock-based compensation expense related to stock options in the years ended December 31, 2021, 2020 and 2019, respectively. The weighted-average grant date fair value of options granted during the year ended December 31, 2019 was $ 9.18 . The total fair value of the shares vested during the years ended December 31, 2021, 2020 and 2019 was $ 2.3 million, $ 1.4 million and $ 1.4 million, respectively. As of December 31, 2021, the total unrecognized cost related to non-vested options was approximately $ 0.6 million. This cost is expected to be recognized over a weighted-average period of 0.9 years. Restricted Stock Units RSUs represent the right to receive a share of common stock at a future date. RSUs granted to employees for service generally vest over four years , with 25 % vesting on the first anniversary of the grant date and the remainder vesting ratably on a quarterly basis thereafter, subject to continued employment. The RSUs granted to non-employee directors generally vest in full on the first anniversary of the grant date. Some RSUs granted to employees for performance vest upon the completion of defined performance goals, subject to continued employment. RSUs are classified as equity awards because the RSUs will be paid in the Company’s common stock upon vesting. The fair value of RSUs is determined at the grant date based on the closing price of the Company's common stock on the date of grant. The related compensation expense is recognized over the service period and is based on the grant date fair value of the Company’s common stock and the number of shares expected to vest. The fair value of the awards is not remeasured at the end of each reporting period. RSUs do not carry voting rights until the RSUs are vested and the underlying shares are released in accordance with the terms of the award. 76 RSU Summary A summary of the Company’s activity for RSUs is as follows: RSUs Weighted- Average Grant Date Fair Value Per RSU (In thousands) Outstanding at December 31, 2018 3,077 $ 10.13 Granted 1,058 22.50 Forfeited ( 102 ) 14.86 Released ( 1,331 ) 10.52 Outstanding at December 31, 2019 2,702 $ 14.62 Granted 1,061 26.73 Forfeited ( 92 ) 17.72 Released ( 1,007 ) 15.63 Outstanding at December 31, 2020 2,664 $ 18.96 Granted 913 41.55 Forfeited ( 115 ) 29.49 Released ( 912 ) 21.12 Outstanding at December 31, 2021 2,550 $ 25.80 Vested and unreleased at December 31, 2021 (1) 860 (1) These RSUs were granted to the Company's board of directors as a part of their compensation for board and committee service and had vested but had not yet settled, meaning that the underlying shares of common stock had not been issued and released. As of December 31, 2021, the total unrecognized cost related to non-vested RSUs was approximately $ 22.2 million. This cost is expected to be recognized over a weighted-average period of 1.36 years. The Company recognized $ 26.0 million, $ 15.7 million and $ 13.8 million of stock-based compensation expense related to RSUs in the years ended December 31, 2021, 2020 and 2019, respectively. Service-Based RSU Awards The majority of the annual compensation the Company provides to non-employee members of its board of directors is paid in the form of RSUs. In addition, some members of the Company’s board of directors elect to receive the remainder of their annual compensation, or a portion thereof, in the form of RSUs. An aggregate amount of approximately 39,000 , 58,000 and 76,000 service-based RSUs were granted to the Company’s non-employee directors as a result of these payments and elections during the years ended December 31, 2021, 2020 and 2019, respectively, with an estimated grant date fair value of $ 1.6 million, $ 1.4 million and $ 1.4 million, respectively. During the years ended December 31, 2021, 2020 and 2019, the Company granted approximately 531,000 , 713,000 and 740,000 service-based RSUs, respectively, to its employees, with an estimated aggregate grant date fair value of $ 22.0 million, $ 19.1 million and $ 16.9 million, respectively. During the years ended December 31, 2021, 2020 and 2019, the Company granted approximately 2,000 , 10,000 and 11,000 service-based RSUs, respectively, to non-employee consultants, with an estimated grant date fair value of $ 0.1 million, $ 0.2 million and $ 0.2 million, respectively. Performance-Based RSU Awards In March 2021, 2020 and 2019, the Company awarded approximately 228,000 , 115,000 and 125,000 performance-based RSUs, respectively, to the Company’s executives and employees (the “Bonus RSUs”), with an estimated grant date fair value of $ 9.5 million, $ 3.1 million and $ 2.9 million, respectively. Vesting of the Bonus RSUs is and was dependent upon the Company’s 77 achievement of defined performance goals over the respective fiscal year. The Company records stock-based compensation expense related to performance-based RSUs when it is considered probable that the performance conditions will be met. Management believes it is probable that substantially all of the 2021 Bonus RSUs will vest. The level of achievement, if any, of performance goals will be determined by the compensation committee of the Company’s board of directors and, if such goals are achieved, the 2021 Bonus RSUs will vest, subject to continued employment, in March 2022. Substantially all of the Bonus RSUs awarded in 2019 and 2020 vested in March 2020 and March 2021, respectively, upon the determination of the level of achievement of the respective performance goals. Additionally, during 2021, 2020 and 2019, the Company awarded approximately 110,000 , 144,000 and 96,000 performance-based RSUs, respectively, to the Company’s executives (the “Executive RSUs”). The estimated aggregate grant date fair value of the Executive RSUs for the 2021, 2020 and 2019 grants was $ 4.6 million, $ 3.9 million and $ 2.2 million, respectively. Vesting of the Executive RSUs is and was dependent upon the Company’s achievement of defined performance goals over a two-year period. The vesting of Executive RSUs will ultimately range from 0 % to 150 % of the number of shares underlying the Executive RSUs granted based on the level of achievement of the performance goals. If the Company achieves the performance goals, 50 % of the number of Executive RSUs earned based on performance will vest on the second anniversary of the grant date, and the remaining 50 % will vest on the third anniversary of the grant date, in each case subject to the executive’s continued service as of the vesting date. During March 2021, 2020 and 2019, the Company awarded additional shares underlying performance-based RSUs to the Company’s executives for over-achievement of performance targets related to the Executive RSUs originally awarded in 2019, 2018 and 2017 in the amounts of 3,000 , 20,000 and 11,000 shares, respectively. 10. Equity Transactions Preferred Stock The Company is authorized to issue 2.0 million shares of preferred stock with a par value of $ 0.0001 per share. The Company previously issued 1.5 million shares of preferred stock. The remaining 0.5 million authorized shares of preferred stock remain undesignated and unissued as of December 31, 2021 and 2020. As of December 31, 2021 and 2020, there were no outstanding shares of preferred stock, as all preferred stock was converted into common stock in prior periods according to its terms. Share Repurchase Program In February 2021, the Company announced that its Board of Directors had authorized the repurchase of up to $ 300.0 million of its common stock through December 31, 2022. This time-frame can be extended or shortened by the Board of Directors. Repurchases are made from time to time on the open market at prevailing prices or in negotiated transactions off the market. All shares are immediately retired upon repurchase in accordance with the board-approved policy. When treasury shares are retired, the Company’s policy is to allocate the excess of the repurchase price over the par value of shares acquired first, to additional paid-in capital, and then to retained earnings. The portion to be allocated to additional paid-in capital is calculated by applying a percentage, determined by dividing the number of shares to be retired by the number of shares outstanding, to the balance of additional paid-in capital as of the date of retirement. The Company repurchased and subsequently retired 4.3 million shares of its common stock during the year ended December 31, 2021, for a total purchase price of $ 163.4 million. As of December 31, 2021, $ 136.6 million remained available and authorized for repurchase under this program. As the share repurchases were authorized in 2021, no shares were permitted to be repurchased during the year ended December 31, 2020. 78 11. Revenue The following table summarizes the Company’s services revenue: Year Ended December 31, 2021 2020 2019 (In thousands) Commercial services: Voice and data $ 175,584 $ 168,668 $ 173,167 IoT data 110,919 96,981 96,435 Broadband 42,990 35,959 30,455 Hosted payload and other data 58,611 60,600 49,969 Total commercial services 388,104 362,208 350,026 Government services 103,887 100,887 97,132 Total services $ 491,991 $ 463,095 $ 447,158 The following table summarizes the Company’s engineering and support services revenue: Year Ended December 31, 2021 2020 2019 (In thousands) Commercial $ 4,613 $ 4,529 $ 2,852 Government 25,825 29,696 27,578 Total $ 30,438 $ 34,225 $ 30,430 The Company's contracts with customers generally do not contain performance obligations with terms in excess of one year. As such, the Company does not disclose details related to the value of performance obligations that are unsatisfied as of the end of the reporting period. The total value of any performance obligations that extend beyond a year is immaterial to the financial statements. The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and deferred revenue (contract liabilities) on the consolidated balance sheets. The Company bills amounts under its agreed-upon contractual terms at periodic intervals (for services), upon shipment (for equipment), or upon achievement of contractual milestones or as work progresses (for engineering and support services). Billing may occur subsequent to revenue recognition, resulting in unbilled accounts receivable (contract assets). The Company may also receive payments from customers before revenue is recognized, resulting in deferred revenue (contract liabilities). The Company recognized revenue that was previously recorded as deferred revenue in the amounts of $ 43.0 million, $ 41.1 million and $ 43.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. The Company has also recorded costs of obtaining contracts expected to be recovered in prepaid expenses and other current assets (contract assets or commissions), that are not separately disclosed on the consolidated balance sheets. The commissions are recognized over the estimated usage period. The following table presents contract assets not separately disclosed: Year Ended December 31, 2021 2020 (In thousands) Contract Assets: Commissions $ 1,190 $ 993 Other contract costs $ 2,558 $ 2,860 Unbilled receivables $ 10,752 $ 9,132 79 12.

As of December 31, 2021, the Company had a net deferred tax asset of $ 1.1 million that is included in other assets on the balance sheet and a net deferred tax liability of $ 134.3 million. The Company recognizes valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. In assessing the likelihood of realization, management considers: (i) future reversals of existing taxable temporary differences; (ii) future taxable income exclusive of reversing temporary differences and carryforwards; (iii) taxable income in prior carryback year(s) if carryback is permitted under applicable tax law; and (iv) tax planning strategies. The Company had deferred tax assets related to cumulative U.S. federal net operating loss carryforwards and interest expense carryforwards of approximately $ 330.2 million and $ 337.1 million as of December 31, 2021 and 2020, respectively. U.S. federal net operating loss carryforwards for periods prior to 2018, if unutilized, will expire in various amounts from 2031 through 2037. The Company believes that the U.S. federal net operating losses will be utilized before the expiration dates and, as such, no valuation allowance has been established for these deferred tax assets. U.S. federal net operating loss carryforwards for 2018 and thereafter and interest expense carryforwards do not expire. The Company had deferred tax assets related to the state net operating loss carryforwards of approximately $ 61.3 million and $ 69.7 million as of December 31, 2021 and 2020, respectively, that expire from 2025 through 2043. The Company does not expect to fully utilize all of its state net operating losses within the respective carryforward periods and as such reflects a partial valuation allowance of $ 32.6 million and $ 30.2 million as of December 31, 2021 and 2020, respectively, against these deferred tax assets on its consolidated balance sheet. The Company had deferred tax assets related to the foreign net operating loss carryforwards of approximately $ 0.6 million and $ 0.7 million, as of December 31, 2021 and 2020, respectively, that begin to expire in 2026. The Company does not expect to fully utilize all of its foreign net operating losses within the carryforward periods. As such, the Company had recorded a partial valuation allowance of $ 0.5 million as of December 31, 2021 , which is unchanged from December 31, 2020, against these deferred tax assets on its consolidated balance sheets. The timing and manner in which the Company will utilize the net operating loss carryforwards in any year, or in total, may be limited in the future as a result of changes in the Company’s ownership and any limitations imposed by the jurisdictions in which the Company operates. The Company had approximately $ 11.1 million and $ 10.0 million of deferred tax assets related to research and development tax credits as of December 31, 2021 and 2020, respectively, that expire in various amounts from 2029 through 2041. The Company had approximately $ 5.6 million and $ 5.7 million of deferred tax assets related to foreign tax credits as of December 31, 2021 and 2020, respectively, that expire in various amounts through 2031. The Company does not expect to utilize all of its foreign tax credits within the respective carryforward periods. As such, the Company had a partial valuation allowance of $ 0.8 million and $ 1.1 million as of December 31, 2021 and 2020, respectively. 81 The Company has provided for U.S. income taxes on all undistributed earnings of its significant foreign subsidiaries since the Company does not indefinitely reinvest these undistributed earnings. The Company measures deferred tax assets and liabilities using tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company recognizes the effect on deferred tax assets and liabilities of a change in tax rates in income in the period that includes the enactment date. Uncertain Income Tax Positions The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Significant judgment is required in evaluating tax positions and determining the provision for income taxes. The Company establishes liabilities for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes may be due. These liabilities are established when the Company believes that certain positions might be challenged despite its belief that its tax return positions are fully supportable. The Company adjusts these liabilities in light of changing facts and circumstances, such as the outcome of a tax audit. The provision for income taxes includes the impact of changes to these liabilities. There were no unrecognized tax benefits as of December 31, 2021 , and the amount of unrecognized tax benefits was $ 0.5 million as of December 31, 2020. Any changes in the next twelve months are not anticipated to have a significant impact on the results of operations, financial position or cash flows of the Company. All of the Company’s uncertain tax positions, if recognized, would affect its income tax expense. The Company has elected an accounting policy to classify interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of December 31, 2021 , there were no interest and penalties on unrecognized tax benefits, and as of December 31, 2020, potential interest and penalties on unrecognized tax benefits were not significant. The Company is subject to tax audits in all jurisdictions for which it files tax returns. Tax audits by their very nature are often complex and can require several years to complete. Currently, there are no U.S. federal, state or foreign jurisdiction tax audits pending. The Company’s corporate U.S. federal and state tax returns from 2011 to 2020 remain subject to examination by tax authorities and the Company’s foreign tax returns from 2013 to 2020 remain subject to examination by tax authorities. The following is a tabular reconciliation of the total amounts of unrecognized tax benefits which includes related interest and penalties: 2021 2020 (In thousands) Balance at January 1, $ 537 $ 953 Change attributable to tax positions taken in a prior period ( 537 ) ( 416 ) Balance at December 31, $ — $ 537 82 13. Net Loss Per Share The Company calculates basic net loss per common share by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. In periods of net income, diluted net income per share takes into account the effect of potentially dilutive common shares when the effect is dilutive. Potentially dilutive common shares include (i) common stock issuable upon exercise of outstanding stock options and (ii) contingent RSUs that are convertible into shares of common stock upon achievement of certain service and performance requirements. The effect of potentially dilutive common shares is computed using the treasury stock method. The computations of basic and diluted net loss per common share are set forth below: Year Ended December 31, 2021 2020 2019 (In thousands, except per share data) Numerator: Net loss attributable to common stockholders - basic and diluted $ ( 9,319 ) $ ( 56,054 ) $ ( 166,193 ) Denominator: Weighted average common shares - basic and diluted 133,530 133,491 125,167 Net loss attributable to common stockholders per share - basic and diluted $ ( 0.07 ) $ ( 0.42 ) $ ( 1.33 ) Due to the Company’s net loss position for the years ended December 31, 2021 , 2020 and 2019 all potential common stock equivalents were anti-dilutive and therefore excluded from the calculation of diluted net loss per share. The incremental number of shares underlying stock options and RSUs outstanding with anti-dilutive effects are presented below: Year Ended December 31, 2021 2020 2019 (In thousands) Performance-based RSUs 183 127 295 Service-based RSUs 536 567 678 Stock options 1,189 1,946 2,522 83 14.

Segments, Significant Customers, Supplier and Service Providers and Geographic Information The Company operates in one business segment, providing global satellite communications services and products. The Company derived approximately 21 %, 22 % and 22 % of its total revenue in the years ended December 31, 2021, 2020 and 2019, respectively, from prime contracts or subcontracts with agencies of the U.S. government. For the years ended December 31, 2021, 2020 and 2019, no single commercial customer accounted for more than 10 % of the Company’s total revenue.

As of December 31, 2021 and 2020, no single commercial customer accounted for more than 10 % of the Company’s total accounts receivable balance. The Company contracts for the manufacture of its subscriber equipment primarily from a limited number of manufacturers and utilizes other sole source suppliers for certain component parts of its devices. Should events or circumstances prevent the manufacturer or the suppliers from producing the equipment or component parts, the Company’s business could be adversely affected until the Company is able to move production to other facilities of the manufacturer or secure a replacement manufacturer or an alternative supplier for such component parts. 84 Net property and equipment by geographic area was as follows: December 31, 2021 2020 (In thousands) United States $ 429,888 $ 421,930 Satellites in orbit 2,228,644 2,487,220 All others 3,804 7,926 Total $ 2,662,336 $ 2,917,076 Revenue by geographic area was as follows: Year Ended December 31, 2021 2020 2019 (In thousands) United States $ 330,948 $ 323,605 $ 300,494 Other countries (1) 283,552 259,834 259,950 Total $ 614,500 $ 583,439 $ 560,444 (1) No single country in this group represented more than 10 % of revenue. Revenue is attributed to geographic area based on the billing address of the distributor. Service location and the billing address are often not the same. The Company’s distributors sell services directly or indirectly to end users, who may be located or use the Company’s products and services elsewhere. The Company cannot provide the geographical distribution of end users because it does not contract directly with them. The Company is exposed to foreign currency exchange fluctuations as foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of sales made and costs incurred in foreign currencies. 16. Employee Benefit Plan The Company sponsors a defined-contribution 401(k) retirement plan (the “Plan”) that covers all employees. Employees are eligible to participate in the Plan on the first day of the month following the date of hire, and participants are 100 % vested from the date of eligibility. The Company matches employees’ contributions equal to 100 % of the salary deferral contributions up to 5 % of the employees’ eligible compensation each pay period. Company matching contributions to the Plan were $ 3.5 million, $ 3.1 million, and $ 3.1 million for the years ended December 31, 2021, 2020 and 2019, respectively. 85 Item 9.
