The CODM makes resource and operating decisions by evaluating performance and business results of the consolidated company. As a result, the Company has a single reportable segment, with net income (loss) utilized as the performance measure.

Basis of Presentation – The accompanying Unaudited Condensed Consolidated Financial Statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conformity with Article 10 of Regulation S-X promulgated under the Securities Act of 1933, as amended (the “Securities Act”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements and should be read in conjunction with our annual audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2026 (the “2025 10-K”). These Unaudited Condensed Consolidated Financial Statements reflect, in the opinion of management, all material adjustments (which include normal recurring adjustments) necessary to fairly state, in all material respects, our financial position, results of operations and cash flows for the periods presented.

The results of operations and cash flows for the three-month period ended March 31, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026.

We hadone class of common stock outstanding as of March 31, 2026 and December 31, 2025.

Use of Estimates – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates the significant estimates and bases such estimates on historical experience and various other assumptions believed to be reasonable under the circumstances. However, actual results could differ materially from those estimates.

2. Earnings Per Share

Basic earnings per share is computed using the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed using the weighted average number of common shares outstanding and the treasury stock method for stock-based compensation. Contingently issuable shares are only included in the diluted earnings per share computation once all necessary conditions have been satisfied.

The diluted earnings per share calculations exclude the effect of stock options, deferred stock units, performance stock units, restricted stock units and the potential Earnout Liability related to the acquisition of Satcom Direct when the computation is anti-dilutive. For the three-month periods ended March 31, 2026 and 2025, the weighted average number of shares excluded from the computation was 51.9 million and 28.7 million, respectively.

The following table sets forth the computation of basic and diluted earnings per share for thethree-month periods ended March 31, 2026 and 2025 (in thousands, except per share amounts):

Remaining performance obligations

As of March 31, 2026, the aggregate amount of the transaction price in our contracts allocated to the remaining unsatisfied performance obligations (“RPO”) was approximately$522 million and excludes consideration from contracts that have an original duration of one year or less. Approximately$512 million of the RPO primarily represents connectivity and entertainment service revenues which are recognized as services are provided, which is expected to occur through the remaining term of the contracts. Our contracts vary in length and generally have terms oftwo toten years. We expect to recognize approximately 38% of our connectivity and entertainment service RPO within the next year, approximately 47% inone tofive years and the remaining 15% infive toten years. The remaining$10 million of the RPO represents future equipment revenue that is expected to be recognized primarily within the next three years as equipment is shipped.

Disaggregation of revenue

The following table presents our revenue disaggregated by category(in thousands):

Contract balances

Our current and non-current contract asset balances totaled $44.1 million and $39.6 million as of March 31, 2026 and December 31, 2025, respectively.

4. Government Assistance

Federal Communications Commission (“FCC”) Reimbursement Program

On July 15, 2022, the Company was notified that it was approved for participation in the FCC Reimbursement Program, designed to reimburse providers of advanced communications services for reasonable costs incurred in the required removal, replacement, and disposal of covered communications equipment or services, that have been deemed to pose a national security risk, from their networks. Pursuant to the FCC Reimbursement Program, the FCC approved up to approximately $334 millionin reimbursements to the Company to cover documented and approved costs to (i) remove and securely destroy all ZTE communications equipment and services in the Company’s terrestrial U.S. networks and replace such equipment and (ii) remove and replace certain equipment installed on aircraft operated by the Company’s ATG customers that is not compatible with the terrestrial equipment that will replace ZTE equipment. Due to an initial shortfall in the amount appropriated by Congress to fund the FCC Reimbursement

Program, approximately $132 million of the approved amount was allocated to the Company under the program. Following passage of the Fiscal Year 2025 National Defense Authorization Act, the Company was allocated its full approved amount of approximately $334 million and the program completion deadline was recently extended to November 8, 2026.

As of March 31, 2026 and December 31, 2025, we have recorded a$41.2 million and $27.8 million receivable from the FCC, respectively, which is included in Prepaid expenses and other current assets in our Unaudited Condensed Consolidated Balance Sheets.

Research and development costs are reported as Engineering, design and development expenses in our Unaudited Condensed Consolidated Statements of Operations.

7. Goodwill and Other Intangible Assets

Our intangible assets are comprised of both indefinite-lived and finite-lived intangible assets and goodwill. Intangible assets with indefinite lives are not amortized but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. We perform our annual impairment test of our indefinite-lived intangible assets during the fourth quarter of each fiscal year, and the results from the test performed in the fourth quarter of 2025 indicated no impairment. We also reevaluate the useful life of indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life.

The carrying value of goodwill was$193.2 million as of both March 31, 2026 and December 31, 2025.

2021 Credit Agreement

On April 30, 2021, Gogo and Gogo Intermediate Holdings LLC (“GIH”) (a wholly owned subsidiary of Gogo) entered into a credit agreement (the “Original 2021 Credit Agreement,” and, as it may be amended, supplemented or otherwise modified from time to time, the “2021 Credit Agreement”) among Gogo, GIH, the lenders and issuing banks party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent, which provides for (i) a term loan credit facility (the “2021 Term Loan Facility”) in an aggregate principal amount of $725.0 million, issued with a discount of 0.5%, and (ii) a revolving credit facility (the “Revolving Facility” and together with the 2021 Term Loan Facility, the “2021 Facilities”) of up to $100.0 million, which includes a letter of credit sub-facility. The 2021 Term Loan Facility matures on April 30, 2028.

On December 3, 2024, Gogo and GIH entered into a second amendment to the 2021 Credit Agreement, by and among, Gogo, GIH, guarantors party thereto, Morgan Stanley Senior Funding, Inc., as administrative agent, and the lenders party thereto, among other purposes, (a) increase the aggregate principal amount of revolving commitments available under the 2021 Credit Agreement to an aggregate amount of revolving commitments equal to $122 million and (b)extend the maturity date of the revolving facility to December 3, 2029 (subject to such maturity date springing to the date that is 90 days prior to the then-current maturity date of (a) the 2021 Term Loan Facility under the 2021 Credit Agreement and (b) the HPS Term Loan Facility under the HPS Credit Agreement under certain conditions).

The 2021 Term Loan Facility amortizes in quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity of the 2021 Term Loan Facility. There are no amortization payments under the Revolving Facility.

The 2021 Term Loan Facility bears annual interest at a floating rate measured by reference to, at GIH’s option, either (i) an adjusted term secured overnight financing rate as administered by the Federal Reserve Bank of New York (“SOFR”) (subject to a floor of 0.75%) plus an applicable margin of 3.75% and a credit spread adjustment of approximately 0.11%, 0.26% or 0.43% per annum based on 1-month, 3-month or 6-month term SOFR, respectively or (ii) an alternate base rate plus an applicable margin of 2.75%.

Loans outstanding under the Revolving Facility bear annual interest at a floating rate measured by reference to, at GIH’s option, either (i)an adjusted term SOFR rate (subject to a floor of 0.00%) plus an applicable margin ranging from 3.50% to 4.00% per annum depending on GIH’s senior secured first lien net leverage ratio or (ii) an alternate base rate plus an applicable margin ranging from 2.50% to 3.00% per annum depending on GIH’s senior secured first lien net leverage ratio. Additionally, unused commitments under the Revolving Facility are subject to a fee ranging from 0.25% to 0.50% per annum depending on GIH’s senior secured first lien net leverage ratio. As of March 31, 2026, the fee for unused commitments under the Revolving Facility was 0.25% and the applicable margin was 4.00% for SOFR rate loans and 3.00% for alternate rate loans.

The 2021 Facilities may be prepaid at GIH’s option at any time without premium or penalty (other than customary breakage costs), subject to minimum principal payment amount requirements. On May 3, 2023, the Company prepaid $100 million of the outstanding principal amount of the 2021 Term Loan Facility. This prepayment satisfied the required amortization payments for the remaining term of the 2021 Term Loan Facility.

Subject to certain exceptions and de minimis thresholds, the 2021 Term Loan Facility is subject to mandatory prepayments in an amount equal to:

•

100% of the net cash proceeds of certain asset sales, insurance recovery and condemnation events, subject to reduction to 50% and 0% if specified senior secured first lien net leverage ratio targets are met;

•

100% of the net cash proceeds of certain debt offerings; and

•

50% of annual excess cash flow (as defined in the 2021 Credit Agreement), subject to reduction to 25% and 0% if specified senior secured first lien net leverage ratio targets are met.

The 2021 Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include restrictions on, among other things: incurrence of indebtedness or issuance of disqualified equity interests; incurrence or existence of liens; consolidations or mergers; activities of Gogo and any subsidiary holding a license issued by the FCC; investments, loans, advances, guarantees or acquisitions; asset sales; dividends or other distributions on equity; purchase, redemption or retirement of capital stock; payment or redemption of certain junior indebtedness; entry into other agreements that restrict the ability to incur liens securing the 2021 Facilities; and amendment of organizational documents; in each case subject to customary exceptions.

The Revolving Facility includes a financial covenant set at a maximum senior secured first lien net leverage ratio of 7.50:1.00, which will apply if the outstanding amount of loans and unreimbursed letter of credit drawings thereunder at the end of any fiscal quarter exceeds 35% of the aggregate of all commitments thereunder.

The 2021 Credit Agreement contains customary events of default, which, if any of them occurred, would permit or require the principal, premium, if any, and interest on all of the then outstanding obligations under the 2021 Facilities to be due and payable immediately and the commitments under the Revolving Facility to be terminated.

The Revolving Facility is available for working capital and general corporate purposes of GIH and its subsidiaries and was undrawn as of March 31, 2026 and December 31, 2025.

As of both March 31, 2026 and December 31, 2025, the outstanding principal amount of the 2021 Term Loan Facility was$601.4 million, the unaccreted debt discount was$1.1 million and$1.2 million, respectively, and the net carrying amount was$600.3 million and $600.2 million, respectively.

We paid approximately $21.6 million of loan origination and financing costs related to the 2021 Facilities, which are being accounted for as deferred financing costs on our Unaudited Condensed Consolidated Balance Sheets and are amortized over the terms of the 2021 Facilities. Total amortization expense was$0.8 million and $0.7 million, respectively, for thethree-month periods ended March 31, 2026 and 2025 and is included in interest expense in our Unaudited Condensed Consolidated Statements of Operations. As of March 31, 2026 and December 31, 2025, the balance of unamortized deferred financing costs related to the 2021 Facilities was$6.7 million and $7.4 million, respectively.

On April 30, 2021, Gogo, GIH, and each direct and indirect wholly-owned U.S. restricted subsidiary of GIH (Gogo and such subsidiaries collectively, the “Guarantors”) entered into a guarantee agreement (the “Guarantee Agreement”) in favor of Morgan Stanley Senior Funding, Inc., as collateral agent (the “Collateral Agent”), whereby GIH and the Guarantors guarantee the obligations under the 2021 Facilities and certain other secured obligations as set forth in the Guarantee Agreement, and GIH and the Guarantors entered into a collateral agreement (the “Collateral Agreement”), in favor of the Collateral Agent, whereby GIH and the Guarantors grant a security interest in substantially all of their respective tangible and intangible assets (including the equity interests in each direct material wholly-owned U.S. restricted subsidiary owned by GIH or any Guarantor, and 65% of the equity interests in any non-U.S. subsidiary held directly by GIH or any Guarantor), subject to certain exceptions, to secure the obligations under the 2021 Facilities and certain other secured obligations as set forth in the Collateral Agreement. The liens granted under the 2021 Term Loan Facility are subject to an intercreditor agreement and arepari passu with the liens granted under the HPS Term Loan Facility (as defined below).

The HPS Term Loan Facility amortizes in quarterly installments equal to one percent of the aggregate initial principal amount thereof per annum, with the remaining balance payable upon final maturity of the HPS Term Loan Facility on April 30, 2028.

The HPS Term Loan Facility bears annual interest at a floating rate measured by reference to, at the Company’s option, either (i) an adjusted term SOFR (subject to a floor of 1.00%) plus an initial applicable margin of 6.00%, which is subject to two leverage-based step-downs of up to 0.25% each or (ii) an alternate base rate plus an applicable margin of 5.00%, which is subject to two leverage-based step-downs of up to 0.25% each.

The HPS Term Loan Facility may be prepaid at the Company’s option, at any time, without premium or penalty (other than customary breakage costs, and except that (a) during the first 12 months following the closing of the HPS Credit Agreement, certain prepayments of the HPS Term Loan Facility are subject to a 3.00% prepayment premium and (b) during the period from 12 months to

24 months following the closing of the HPS Credit Agreement, certain prepayments of the HPS Term Loan Facility are subject to a 1.00% prepayment premium), subject to minimum principal repayment amount requirements.

Subject to certain exceptions and de minimis thresholds, the HPS Term Loan Facility is subject to mandatory prepayments in an amount equal to:

•

100% of the net cash proceeds of certain asset sales, insurance recovery and condemnation events;

•

100% of the net cash proceeds of certain debt offerings; and

As of March 31, 2026 and December 31, 2025, the outstanding principal amount of the HPS Term Loan Facility was$246.3 million and $246.9 million, respectively, the unaccreted debt discount was$3.3 million and $3.6 million, respectively, and the net carrying amount was$243.0 million and $243.3 million, respectively. In accordance with the HPS Credit Agreement, the Company paid $21.1 million of the outstanding principal amount of the HPS Term Loan Facility in April 2026.

We paid approximately $2.2 million of loan origination and financing costs related to the HPS Credit Agreement which are being accounted for as deferred financing costs on our consolidated balance sheets and are amortized over the term of the HPS Credit Agreement. Total amortization expense was$0.1 million and $0.1 million, respectively, for the three-month periods ended March 31, 2026 and 2025 and is included in interest expense in our Unaudited Condensed Consolidated Statements of Operations. As of March 31, 2026 and December 31, 2025 the balance of unamortized deferred financing costs related to the HPS Credit Agreement was$1.4 million and $1.6 million, respectively.

The liens granted under the HPS Term Loan Facility are subject to an intercreditor agreement and arepari passu with the liens granted under the 2021 Term Loan Facility.

9. Derivative Instruments and Hedging Activities

We are exposed to interest rate risk on our variable rate borrowings. We currently use interest rate caps to manage our exposure to interest rate changes, and have designated these interest rate caps as cash flow hedges for accounting purposes. Accordingly, the earnings impact of the derivatives designated as cash flow hedges is recorded upon the recognition of the variable interest payments related to the hedged debt.

In May 2021, we purchased interest rate caps with an aggregate notional amount of $650.0 million for $8.6 million. The cost of the interest rate caps will be amortized to interest expense using the caplet method, from the effective date through termination date. We receive payments in the amount calculated pursuant to the caps for any period in which the daily compounded SOFR rate plus a credit spread adjustment recommended by the Alternative Reference Rate Committee of 0.26% increases beyond the applicable strike rate. The notional amounts of the interest rate caps periodically decrease over the life of the caps.

The notional amounts, strike rates and end dates of the cap agreements are as follows(notional amounts in thousands):

We record the effective portion of changes in the fair value of our cash flow hedges to other comprehensive income (loss), net of tax, and subsequently reclassify these amounts into earnings in the period during which the hedged transaction is recognized. The amounts included in accumulated other comprehensive income (loss) will be reclassified to interest expense in the event the hedges are no longer considered effective, in accordance with ASC 815, Derivatives and Hedging. No gains or losses of our cash flow hedges were considered to be ineffective and reclassified from other comprehensive income (loss) to earnings for thethree-month periods ended March 31, 2026 and 2025. We estimate that approximately$1.3 million currently recorded in accumulated other comprehensive income (loss) will be recognized in earnings over the next 12 months. We assess the effectiveness of the hedges on an ongoing basis, and the remaining outstanding caps are still considered to be highly effective, and remain designated as a cash flow hedge. Cash flows from interest rate caps are classified in the Unaudited Condensed Consolidated Statements of Cash Flows as investing activities.

For the three-month period ended March 31, 2026, we recorded a decreasein fair value on the interest rate caps of $0.1 million, net of an immaterial amount of tax, and for thethree-month period ended March 31, 2025, we recorded a decrease in fair value on the interest rate caps of$3.0 million, net of tax of $0.8 million. Increases and decreases in fair value on interest rate caps above exclude amortization of the purchase price paid for the interest rate caps.

When derivatives are used, we are exposed to credit loss in the event of non-performance by the counterparties; however, non-performance is not anticipated. ASC 815, Derivatives and Hedging, requires companies to recognize all derivative instruments as either assets or liabilities at fair value in the balance sheet. The fair values of the interest rate derivatives are based on quoted market prices for similar instruments from commercial banks (based on significant observable inputs - Level 2 inputs).

The following table presents the fair value of our interest rate derivatives included in the Unaudited Condensed Consolidated Balance Sheets for the periods presented (in thousands):

Fair Value Measurement

Our derivative assets and liabilities consist principally of interest rate caps, which are carried at fair value based on significant observable inputs (Level 2 inputs). Derivatives entered into by us are typically executed over-the-counter and are valued using discounted cash flows along with fair value models that primarily use market observable inputs. These models take into account a variety of factors including, where applicable, maturity, interest rate yield curves, and counterparty credit risks.

10. Interest Costs

We capitalize a portion of our interest on funds borrowed during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and amortized over the useful lives of the assets.

The following is a summary of our interest costs for thethree-month periods ended March 31, 2026 and 2025(in thousands):

11. Fair Value of Financial Assets and Liabilities

A three-tier fair value hierarchy has been established which prioritizes the inputs used in measuring fair value. These tiers include:

•

Level 1 - defined as observable inputs such as quoted prices for identical assets or liabilities in active markets;

•

Level 2 - defined as observable inputs other than Level 1 inputs such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or 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.

Refer to Note 9, “Derivative Instruments and Hedging Activities,” for fair value information relating to our interest rate caps.

Earnout Liability:

In connection with the acquisition of Satcom Direct, LLC and certain of its affiliates (collectively, “Satcom Direct”) in December 2024, the purchase price included up to an additional $225 million in potential earnout payments of cash and/or common stock of the Company tied to realizing certain financial performance milestones over a four-year period following the acquisition (the “Earnout Liability”). The fair value of the Earnout Liability was calculated using a Monte Carlo simulation based on future gross profit projections of Satcom Direct, gross profit volatility rates of comparable companies and a risk adjusted discount rate. The fair value measurement was based on significant unobservable inputs and thus represents a Level 3 measurement. The Earnout Liability has an estimated fair value of$67.0 million and $71.9 million as of March 31, 2026 and December 31, 2025, respectively. In April 2026, the Company paid cash of $40.0 million related to the 2025 financial performance milestones of the Earnout Liability.

Investment in Convertible Note:

On February 26, 2024, Gogo invested $5 million in a convertible note offering (“Investment in Convertible Note”). The Investment in Convertible Note accrues interest at 5%per annum, payable upon maturity of the note or upon conversion, and matures two years after the date of issuance. In February 2026, the maturity date of the note was extended for two additional years. In connection with the amendment, the Company was issued warrants to purchase common stock of the issuer. We have elected to measure our Investment in Convertible Note, including the warrants, using the fair value option and record changes in fair value, including accrued interest, in Other (income) expense, net on the Unaudited Condensed Consolidated Statements of Operations. The

Company elected the fair value option for the Investment in Convertible Note to eliminate complexities of applying certain accounting models.

The Investment in Convertible Note is included in Other non-current assets and in Prepaid and other current assets on our Unaudited Condensed Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025, respectively, andthe reconciliation of beginning and ending balances were as follows(in thousands):

As of March 31, 2026 and December 31, 2025, our only financial assets and liabilities disclosed but not measured at fair value are the 2021 Term Loan Facility and the HPS Term Loan Facility, which are reflected on the consolidated balance sheets at cost. The fair value measurements are classified as Level 2 within the fair value hierarchy since they are based on quoted market prices of our instruments in markets that are not active. We estimated the fair values of the 2021 Term Loan Facility and the HPS Term Loan Facility by calculating the upfront cash payments a market participant would require to assume these obligations. The upfront cash payments used in the calcula tions of fair values on our Unaudited Condensed Consolidated Balance Sheets, excluding any issuance costs, are the amounts that a market participant would be willing to lend at such date to an entity with a credit rating similar to ours and that would allow such an entity to achieve sufficient cash inflows to cover the scheduled cash outflows under the 2021 Term Loan Facility and HPS Term Loan Facility.

The fair value and carrying value of debt as of March 31, 2026 and December 31, 2025 were as follows(in thousands):

(1)

Fair value amounts are rounded to the nearest million.

(2)

Carrying value of the 2021 Term Loan Facility reflects the unaccreted debt discount of$1.1 million and $1.2 million as of March 31, 2026 and December 31, 2025, respectively. See Note 8, “Long-Term Debt and Other Liabilities,” for further information.

(3)

Carrying value of the HPS Term Loan Facility reflects the unaccreted debt discount of$3.3 million and $3.6 million as of March 31, 2026 and December 31, 2025, respectively. See Note 8, “Long-Term Debt and Other Liabilities,” for further information.

12. Income Tax

The effective income tax rates for the three-month periods ended March 31, 2026 and 2025 were 37.8% and 36.6%, respectively. For the three-month period ended March 31, 2026, our effective income tax rate was higher than the U.S. federal statutory rate of 21% primarily due to state income taxes, the establishment of a valuation allowance on deferred tax assets, stock-based compensation, and nondeductible officer’s compensation. For the three-month period ended March 31, 2025, our effective income tax rate was higher than the U.S. federal statutory rate of 21% primarily due to state income taxes and stock-based compensation.

We regularly assess the need for a valuation allowance related to our deferred income tax assets to determine, based on the weight of all available positive and negative evidence, whether it is more likely than not that some or all of such deferred assets will not be realized. In our assessments, the Company considers recent financial operating results, the scheduled expiration of our net operating losses, future taxable income, the reversal of existing taxable differences, and tax planning strategies. The remaining valuation allowance is still required for deferred tax assets related to foreign, state and local net operating losses and a valuation allowance related to our convertible note investment, as it is more likely than not as of March 31, 2026 that these deferred tax assets will not be realized.

We are subject to taxation and file income tax returns in the United States federal jurisdiction, various states, and several foreign jurisdictions including, but not limited to, Canada, Switzerland, United Kingdom, Australia, Brazil and Singapore. With a few exceptions, as of March 31, 2026, we are no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2010.

We record penalties and interest relating to uncertain tax positions in the income tax provision line item in the Unaudited Condensed Consolidated Statements of Operations. No penalties or interest related to uncertain tax positions were recorded for thethree-month periods ended March 31, 2026 and 2025, and as of March 31, 2026 and December 31, 2025, we didnot have a liability recorded for interest or potential penalties.

13. Stock-Based Compensation and Retirement Plans

Stock-Based Compensation —As of March 31, 2026, we maintained the 2024 Omnibus Equity Incentive Plan (the “2024 Plan”). The 2024 Plan provides for the grant of both equity and cash awards, including non-qualified stock options, incentive stock options, stock appreciation rights, performance awards (shares and units), restricted stock, restricted stock units (“RSUs”), deferred share units and other stock-based awards and dividend equivalents to eligible employees, directors and consultants, as determined by the Compensation Committee of our Board of Directors. See Note 14, “Stock-Based Compensation and Retirement Plans,” in our 2025 10-K for further information regarding the 2024 Plan. The majority of our equity grants are awarded on an annual basis.

Additionally, in connection with the Company’s acquisition of Satcom Direct on December 3, 2024,2,275,000 shares were granted, consisting of a combination of RSUs and performance-based restricted stock units (“PSUs”) (together, the “Inducement Awards”) by the Compensation Committee. The RSUs will vest in equal annual installments over thefive-year period following the grant date. The PSUs are subject to performance-based vesting and will vest when the performance-based vesting conditions are met. Though not awarded pursuant to the 2024 Plan, the Inducement Awards have been issued subject to the terms and conditions of the 2024 Plan.

For the three-month period ended March 31, 2026, no options to purchase shares of common stock were granted, options to purchase 10,015 shares of common stock were exercised, no options to purchase shares of common stock were forfeited and 34,092 options to purchase shares of common stock expired.

For the three-month period ended March 31, 2026,1,827,850 RSUs were granted,575,396 RSUs vested and 146,777 RSUs were forfeited. The fair value of the RSUs granted during thethree-month period ended March 31, 2026 was approximately$8.5 million, which will generally be recognized over a period offour years.

For the three-month period ended March 31, 2026,101,362 deferred stock units were granted and none were vested or forfeited. The fair value of the deferred stock units granted during thethree-month period ended March 31, 2026 was approximately$0.4 million, which will generally be recognized over a period of 12 months.

For the three-month period ended March 31, 2026,49,822 shares of common stock were issued under the Employee Stock Purchase Plan.

The following is a summary of our stock-based compensation expense by operating expense line in the Unaudited Condensed Consolidated Statements of Operations(in thousands):

Retirement Plans — We have a 401(k) plan for U.S.-based employees, as well as various defined contribution plans for international employees. Eligible U.S. employees may make tax-deferred contributions under the 401(k) plan, subject to Internal Revenue Service limitations. We match contributions towards the 401(k) plan and international defined contribution plans, subject to annual limitations. Our matching contributions were$0.8 million and$1.1 million, respectively, during the three-month periods ended March 31, 2026 and 2025.

14. Leases

Operating and Financing Leases — We determine whether a contract contains a lease at contract inception and calculate the lease liability and right-of-use asset using our incremental borrowing rate. We have operating lease agreements primarily related to cell sites, data centers, satellites and office buildings. Our cell site leases generally have terms offivetoten years, with renewal options for an additional five to 25 years. For certain cell sites, the renewal options are deemed to be reasonably certain to be exercised. Our data center leases have original terms between one to four years with unlimited one-year renewal options, some of which are reasonably certain to be exercised. Our building leases have original terms of ten years, with renewal options for an additional five years. We recognize operating lease expense on a straight-line basis over the lease term. As of March 31, 2026, there were no significant leases which had not commenced.

The following is a summary of our lease expense included in the Unaudited Condensed Consolidated Statements of Operations (in thousands):

(1)Includes $9.0 million of short-term lease cost for the three-month period ended March 31, 2026.

15. Commitments and Contingencies

Contractual Commitments – We have agreements with various vendors under which we have remaining commitments to purchase hardware components and development services. Such commitments will become payable as we receive the hardware components, or as development services are provided.

SmartSky Litigation –On February 28, 2022, SmartSky Networks, LLC (“SmartSky”) brought suit against Gogo Inc. and its subsidiary Gogo Business Aviation LLC in the U.S. District Court for the District of Delaware (the “Court”) alleging that Gogo 5G infringes four patents owned by the plaintiff. On February 21, 2023, the plaintiff amended its complaint to allege that Gogo 5G infringes two additional patents that had been recently issued to the plaintiff. The suit seeks compensatory damages as well as treble damages for alleged willful infringement and reimbursement of plaintiff's costs, disbursements and attorneys' fees. On May 29, 2024, Gogo Inc. and its subsidiary Gogo Business Aviation LLC amended their answer and counterclaims in the same suit, alleging that three of the six patents asserted by the plaintiff are unenforceable due to inequitable conduct before the U.S. Patent Office. A number of dispositive motions were filed on October 25, 2025, and the Court issued orders resolving those motions. SmartSky’s motions were denied. Gogo’s motion for summary judgment of invalidity on one of SmartSky’s asserted patents was granted. The Court also granted Gogo’s motion for summary judgment of no lost profits and Gogo’s motion to exclude SmartSky’s damages expert’s opinions on lost profits and reasonable royalty damages. On November 17, 2025, the Court commenced a jury trial on the plaintiff’s claims. On November 21, 2025, the jury determined that Gogo willfully infringed the plaintiff’s asserted patents and returned a verdict in the total amount of $22.7 million. A one-day bench trial was held on March 4, 2026, to address Gogo’s inequitable conduct defense. Post-trial briefs on the jury trial were filed on March 18, 2026, and post-trial briefs on the bench trial were filed on March 30, 2026. Briefing is expected to be completed on these motions by May 8, 2026. We continue to vigorously defend our position in the infringement suit challenging both the verdict and the amount of the award in the trial court and will do so in the appellate court if necessary. The outcome of the underlying litigation is inherently uncertain. No judgment has been entered and Gogo has not paid any portion of the award.

On March 5, 2024, Gogo Inc. and its subsidiary Gogo Business Aviation LLC filed counterclaims in the same suit, alleging that SmartSky’s ATG network, Flagship equipment, and LITE ATG equipment infringe three patents owned by Gogo. Gogo’s counterclaim suit seeks an unspecified amount of compensatory damages as well as reimbursement of Gogo's costs and attorneys' fees. On April 10, 2024, the Court held that Gogo's counterclaims would proceed under a separate schedule and would be tried separately from SmartSky's claims. On December 31, 2025, Gogo Inc. and its subsidiary Gogo Business Aviation LLC amended their counterclaims to add Apcela IFC JV, LLC as a counterclaim defendant. Under a schedule agreed upon by the parties, fact discovery and claim construction proceedings will be substantially completed by June 26, 2026, and expert discovery by September 25, 2026, with dispositive motions to follow. A trial date has been scheduled for March 8, 2027.

On December 16, 2024, SmartSky sued Gogo Inc. and its subsidiaries in the U.S. District Court for the Western District of North Carolina alleging that Gogo maintains an illegal monopoly over air-to-ground broadband inflight connectivity products and services and has blocked SmartSky from entering the market in violation of antitrust laws. SmartSky also alleges claims of false advertising, unfair and deceptive trade practices, and tortious interference. The suit seeks actual damages, treble damages, punitive damages, disgorgement of profits, reimbursement of plaintiff's costs, attorneys' fees, pre- and post-judgment interest, and interest on actual damages. On March 14, 2025, Gogo Inc. and its subsidiary Gogo Business Aviation LLC filed a motion to dismiss for failure to state a claim. That motion is still pending. On April 21, 2026, at SmartSky’s request, the parties filed a joint motion to modify the case schedule with fact discovery set to be completed by October 2, 2026 and expert discovery by January 31, 2027, with dispositive motions to follow. That motion is still pending and a trial date has not been set. We will vigorously defend our position in this lawsuit. The outcome of the litigation is inherently uncertain.

From time to time we may become involved in legal proceedings arising in the ordinary course of our business. We cannot predict with certainty the outcome of any litigation or the potential for future litigation. With respect to such legal proceedings, we accrue a loss when it is probable and its amount can be reasonably estimated. Regardless of the outcome of any particular litigation and the merits of any particular claim, litigation can have a material adverse impact on our Company due to, among other reasons, any injunctive relief granted, which could inhibit our ability to operate our business, amounts paid as damages or in settlement of any such matter, diversion of management resources and defense costs. The Company’s accrual for probable and estimable loss contingencies for the aforementioned litigation in which we are a defendant was $10.0 million and $11.5 million as of March 31, 2026 and December 31, 2025, respectively, and is recorded in Accrued liabilities on the Consolidated Balance Sheets.
