Iridium Communications Inc.
Notes to Condensed Consolidated Financial Statements
1. Basis of Presentation and Principles of Consolidation
Iridium Communications Inc. (the “Company”) has prepared its condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The Company's operations are conducted through, and its operating assets are owned by, its principal operating subsidiary, Iridium Satellite LLC, Iridium Satellite's immediate parent, Iridium Holdings, LLC, and their subsidiaries. The accompanying condensed 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.
In the opinion of management, the condensed consolidated financial statements reflect all normal recurring adjustments that the Company considers necessary for the fair presentation of its results of operations and cash flows for the interim periods covered, and of the financial position of the Company at the date of the interim condensed consolidated balance sheet. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to instructions, rules and regulations prescribed by the U.S. Securities and Exchange Commission (“SEC”). These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2020, as filed with the SEC on February 11, 2021.

2. Significant Accounting Policies

Adopted 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. Adoption of ASU 2019-12 on January 1, 2021 had no impact on the Company's consolidated financial statements and related disclosures.

Recent Accounting Developments Not Yet Adopted

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 applying U.S. GAAP to 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 by 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 June 30, 2021, the Company has not yet modified any contracts nor adopted any expedients as a result of reference rate reform and is evaluating 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.

8


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 carrying values of the following financial instruments approximated their fair values as of June 30, 2021 and December 31, 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 fixed income debt investments and derivative financial instruments as Level 2. The Company did not hold any Level 3 assets as of June 30, 2021 and December 31, 2020.

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 condensed 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 (“TPN”) 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.

Derivative Financial Instruments

The Company uses an interest rate swap agreement to manage its exposure to fluctuating interest rate risk on variable rate debt. Its derivative is measured at fair value and is recorded on the condensed consolidated balance sheets within other current liabilities. The Company’s derivative is designated as a cash flow hedge, with the effective portion of the changes in fair value of the derivative recorded in accumulated other comprehensive loss within the Company’s condensed consolidated balance sheets and subsequently recognized in earnings when the hedged item impacts 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 condensed consolidated statements of operations and comprehensive 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 used for any gains or losses associated with the hedged item. Cash flows from hedging activities are included in operating activities within the Company’s condensed consolidated statements of cash flows, which is the same category as the item being hedged. See Note 6 for further information.

Cash and Cash Equivalents

The following table presents the Company’s cash and cash equivalents as of June 30, 2021 and December 31, 2020:

Fixed income debt securities$$2,005 Level 2
Total cash and cash equivalents$213,408 $237,178  

Marketable Securities

As of June 30, 2021, the Company's marketable securities consisted of only fixed income debt securities. The amortized cost of these securities amounted to $6.0 million and $7.6 million as of June 30, 2021 and December 31, 2020, respectively. The estimated fair value of these securities amounted to $6.0 million and $7.5 million as of June 30, 2021 and December 31, 2020, respectively. The gross unrealized gains and gross unrealized losses on these marketable securities were not material as of June 30, 2021 and December 31, 2020. All marketable securities are classified as Level 2 investments in the fair value hierarchy. The Company determined that any decline in fair value of these investments is temporary as the Company does not intend to sell these securities and it is not likely that the Company will be required to sell the securities before the recovery of their amortized cost basis.

The following table presents the contractual maturities of the Company's fixed income debt securities as of June 30, 2021 and December 31, 2020:

4. Leases

Lessor Arrangements
Operating leases in which the Company is a lessor consist primarily of hosting agreements with Aireon LLC (“Aireon”) (see Note 12) 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 $5.3 million for each of the three months ended June 30, 2021 and 2020 and $10.7 million for each of the six months ended June 30, 2021 and 2020. Lease income is recorded as hosted payload and other data service revenue within service revenue on the Company’s condensed consolidated statements of operations and comprehensive loss.

Both Aireon and L3Harris have made payments pursuant to their hosting agreements, and the Company expects they will continue to do so. The following table presents future income with respect to the Company’s operating leases in which it is the lessor existing at June 30, 2021, exclusive of the $10.7 million recognized during the six months ended June 30, 2021, by year and in the aggregate:

5. 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 “Term Loan”) and an accompanying $100.0 million revolving loan (the “Revolving Facility”). The Term Loan was issued at a price equal to 99.5% of its face value. While it initially bore interest at an annual rate of LIBOR plus 3.75%, with a 1.0% LIBOR floor, it was repriced in January 2021. It now bears interest at an annual rate of LIBOR plus 2.75%, with a 1.0% LIBOR floor, with a maturity date in November 2026. The interest rate on the Revolving Facility remains 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 amount of the loan following the additional $200.0 million drawn on February 7, 2020, as noted below), with the remaining principal due upon maturity.

On February 7, 2020, the Company closed on an additional $200.0 million under its Term Loan. On February 13, 2020, the Company used these proceeds, together with cash on hand, to prepay and retire all of the indebtedness outstanding under the senior unsecured notes (the “Notes”), including premiums for early prepayment. The additional amount is fungible with the original $1,450.0 million, having the same maturity date, interest rate and other terms, but was issued at a 1.0% premium to face value. 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 three months ended March 31, 2020.

As of June 30, 2021 and December 31, 2020, the Company reported an aggregate of $1,628.8 million and $1,637.6 million in borrowings under the Term Loan, respectively. These amounts do not include $22.1 million and $24.0 million of net unamortized deferred financing costs as of June 30, 2021 and December 31, 2020, respectively. The net principal balance in borrowings in the accompanying condensed consolidated balance sheets as of June 30, 2021 and December 31, 2020 amounted to $1,606.7 million and $1,613.6 million, respectively. As of June 30, 2021 and December 31, 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 $1,638.0 million and $1,647.9 million, respectively. The Company had not borrowed under the Revolving Facility as of June 30, 2021 and December 31, 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 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. The Company’s mandatory excess cash flow prepayment, as specified in the Credit Agreement, was calculated to be $12.7 million as of December 31, 2020. Lenders have the right to decline payment. As such, the Company paid
11


$4.7 million to lenders who did not decline payment in May 2021. This amount counts towards the Company's required quarterly principal payments. The Credit Agreement permits repayment, prepayment, and repricing transactions.

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 June 30, 2021.

Interest on Debt

Total interest incurred, which includes amortization of deferred financing fees and capitalized interest, was $18.8 million and $23.5 million during the three months ended June 30, 2021 and 2020, respectively, and $42.6 million and $51.4 million during the six months ended June 30, 2021 and 2020, respectively. To reprice the Term Loan, the Company incurred financing costs of $3.6 million, which were expensed and are included within interest expense on the condensed consolidated statements of operations and comprehensive loss for the six months ended June 30, 2021. There were no such costs during the six months ended June 30, 2020. Amortization of deferred financing fees was $1.0 million and $0.9 million during the three months ended June 30, 2021 and 2020, respectively and $2.0 million and $1.8 million during the six months ended June 30, 2021 and 2020, respectively. Capitalized interest was $0.7 million and $0.8 million during the three months ended June 30, 2021 and 2020, respectively, and $1.3 million and $1.5 million during the six months ended June 30, 2021 and 2020, respectively. At each of June 30, 2021 and December 31, 2020, accrued interest was $0.2 million.

6. 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 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 interest rate swap 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 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 or is exercised, or no longer qualifies for hedge accounting, 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”) effective 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 receives variable interest payments based on one-month LIBOR from the counterparty. The Company pays a fixed rate of 1.565% on the Swap. The Swap carried a notional amount of $1,000.0 million as of June 30, 2021 and December 31, 2020.

The Company also entered into an interest rate swaption agreement (“Swaption”), for which the Company pays a fixed annual rate of 0.50%. The Swaption carried a notional amount of $1,000.0 million as of December 31, 2020. The Company sold the Swaption in May 2021 for $0.7 million. The Company will continue to pay the fee for the Swaption through November 2021. For this premium liability associated with the Swaption, the Company had a current liability balance of $2.1 million as of June 30, 2021. As of 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.

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 are recorded in accumulated other comprehensive loss and reclassified into earnings during the period in which the hedged transaction affects earnings. Over the next 12 months, the Company expects any gains or losses for cash flow hedges reclassified from accumulated other comprehensive loss into earnings to have an immaterial impact on the Company’s condensed consolidated financial statements.

Fair Value of Derivative Instruments

As of June 30, 2021 and December 31, 2020, the Company had a current liability balance of $2.4 million and $5.2 million, respectively, for the fair value of the Swap recorded in other current liabilities.

During the three and six months ended June 30, 2021, the Company collectively incurred $2.1 million and $4.8 million, respectively, in net interest expense for the swap contracts. During three and six months ended June 30, 2020, the Company collectively incurred $2.7 million and $3.7 million, respectively, in net interest expense for the swap contracts. Gains and losses resulting from fair value adjustments to the swap contracts are recorded within accumulated other comprehensive loss within the Company’s condensed consolidated balance sheets and reclassified to interest expense on the dates that interest payments become due. Cash flows related to the swap contracts are included in cash flows from operating activities on the condensed consolidated statements of cash flows. The amount of unrealized gain related to the swap contracts that was recorded in comprehensive loss in the condensed consolidated statements of operations and comprehensive loss was $0.2 million for the three months ended June 30, 2021, net of an immaterial tax impact, and $1.1 million for the three months ended June 30, 2020, net of a $0.4 million tax impact. The amount of unrealized gain recorded in comprehensive loss was $4.1 million for the six months ended June 30, 2021, net of a $1.2 million tax impact. The amount of unrealized loss recorded in comprehensive loss was $10.8 million for the six months ended June 30, 2020, net of a $3.8 million tax impact.

7. 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 June 30, 2021, the remaining aggregate number of shares of the Company’s common stock available for future grants under the Amended 2015 Plan was 10,468,376. 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) 1 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 known 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 Option Awards

The fair value of stock options is determined at the grant date using the Black-Scholes option pricing model. 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.

The Company historically granted stock options to newly hired and promoted employees, but now almost exclusively utilizes RSUs. The Company did not grant any stock options during the six-month periods ended June 30, 2021 and 2020.

Restricted Stock Units

The 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. The Company’s RSUs are classified as equity awards because the RSUs will be paid in the Company’s common stock upon vesting. 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. The awards do not carry voting rights until they are vested and released in accordance with the terms of the award.

(1)     These RSUs were granted to the Company's board of directors as a part of their compensation for board and committee service, as detailed below, and had vested but had not yet been issued and released, pursuant to the terms of the applicable compensation program.

Service-Based RSUs

The majority of the annual compensation the Company provides to members of its board of directors is paid in the form of RSUs. In addition, certain 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 and 58,000 service-based RSUs were granted to the Company’s directors as a result of these payments and elections during the six months ended June 30, 2021 and 2020, respectively, with an estimated grant date fair value of $1.6 million and $1.4 million, respectively.

During the six months ended June 30, 2021 and 2020, the Company granted approximately 461,000 and 683,000 service-based RSUs, respectively, to its employees, with an estimated aggregate grant date fair value of $19.2 million and $18.3 million, respectively.

During the six months ended June 30, 2021 and 2020, the Company granted approximately 2,000 and 10,000 RSUs to non-employee consultants that are generally subject to service-based vesting. The RSUs granted will vest 50% on the first anniversary of the grant date, and the remaining 50% will vest quarterly thereafter through the second anniversary of the grant date. The estimated aggregate grant date fair value of the RSUs granted to non-employee consultants during the six months ended June 30, 2021 and 2020 was $0.1 million and $0.2 million, respectively.

Performance-Based RSUs

In March 2021 and 2020, the Company granted approximately 228,000 and 115,000 annual incentive, 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 and $3.1 million, respectively. Vesting of the Bonus RSUs is and was dependent upon the Company’s 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
15


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 2020 Bonus RSUs vested in March 2021 upon the determination of the level of achievement of the performance goals.

Additionally, in March 2021 and 2020, the Company granted approximately 110,000 and 144,000 long-term, performance-based RSUs, respectively, to the Company’s executives (the “Executive RSUs”). The estimated aggregate grant date fair value of the Executive RSUs was $4.6 million for the 2021 grants and $3.9 million for the 2020 grants. 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 and 2020, 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 and 2018 in the amounts of 3,000 shares and 20,000 shares, respectively.

8. 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 1.0 million shares and 0.5 million shares of preferred stock. The remaining 0.5 million authorized shares of preferred stock remain undesignated and unissued as of June 30, 2021 and December 31, 2020. As of June 30, 2021 and December 31, 2020, there were no outstanding shares of preferred stock, as all previously outstanding preferred stock was converted into common stock during prior periods, according to its terms.

Share Repurchases and Retirement

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 1.7 million and 3.3 million shares of its common stock during the three and six months ended June 30, 2021, respectively, for a total purchase price of $63.1 million and $122.5 million, respectively. No shares were repurchased during the year ended December 31, 2020. As of June 30, 2021, $177.6 million remained available and authorized for repurchase under this program.

Approximately 26% and 35% of the Company's accounts receivable balance at June 30, 2021 and December 31, 2020, respectively, was due from prime contracts or subcontracts with agencies of the U.S. government.

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 are 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 condensed 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 $10.2 million and $11.5 million during the three months ended June 30, 2021 and 2020, respectively, and $21.8 million and $24.0 million during the six months ended June 30, 2021 and 2020, 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 condensed consolidated balance sheets. The commissions are recognized over the estimated usage period. The following table presents contract assets not separately disclosed as of June 30, 2021 and December 31, 2020:

10. Income Tax Benefit

Loss before income taxes was $6.2 million and $19.9 million for the three and six months ended June 30, 2021, respectively while the income tax benefit was $10.0 million and $18.6 million for the three and six months ended June 30, 2021, respectively. The effective tax rates were 180.3% and 97.8% for the three and six months ended June 30, 2021, respectively, which differed from the federal statutory rate of 21% primarily due to the net impact of a discrete state tax benefit associated with a state apportionment change. During the second quarter of 2021, the Company changed its state apportionment estimate
17


to reflect state planning that required certain beginning deferred tax balances to be revalued. The revaluation resulted in a one-time discrete tax benefit of $8.3 million. The effective tax rate was also impacted by a discrete tax benefit associated with the stock compensation tax deduction and tax benefits from U.S. state tax losses and the Company's U.S. tax credits. These favorable impacts were partially offset by the impact of a discrete tax expense associated with an increase in the prior year valuation allowance for state net operating losses and the limitation on the tax deduction for executive compensation.

Loss before income taxes was $17.0 million and $61.4 million for the three and six months ended June 30, 2020, respectively, while the income tax benefit was $4.6 million and $17.3 million for the three and six months ended June 30, 2020, respectively. The effective tax rates were 28.10% and 28.41% for the three and six months ended June 30, 2020, respectively, which differed from the federal statutory rate of 21% primarily due to the net impact of the tax benefits from U.S. state tax losses and discrete tax benefits associated with the stock compensation tax deduction and the Company’s U.S. tax credits. These favorable impacts were partially offset by the impact of the discrete tax expense associated with an increase in the prior year valuation allowance for state net operating losses.

11. Net Income (Loss) Per Share

The Company calculates basic net income (loss) per share by dividing net income (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 potential 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) contingently issuable 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 RSUs granted to members of the Company’s board of directors contain non-forfeitable rights to dividends and therefore are considered to be participating securities in periods of net income. As a result, the calculation of basic and diluted net income per share excludes net income attributable to the unvested RSUs granted to the Company’s board of directors from the numerator and excludes the impact of the unvested RSUs granted to the Company’s board of directors from the denominator.

The following table summarizes the computations of basic and diluted net income (loss) per share for the three and six months ended June 30, 2021 and 2020:

Due to the Company’s net loss position for the six months ended June 30, 2021, and both the three and six months ended June 30, 2020, all potential common stock equivalents were anti-dilutive and therefore excluded from the calculation of diluted net loss per share. Unvested performance-based RSUs were not included in the computation of basic and diluted net loss per share as certain performance criteria had not yet been satisfied. The following table presents the incremental number of shares underlying stock options and RSUs outstanding with anti-dilutive effects, for the three and six months ended June 30, 2021 and 2020:

Aireon LLC and Aireon Holdings LLC

The Company's satellite constellation hosts the Aireon® system, which provides a global air traffic surveillance service through a series of automatic dependent surveillance-broadcast (“ADS-B”) receivers. The Company formed Aireon in 2011, with subsequent investments from the air navigation service providers (“ANSPs”) of Canada, Italy, Denmark, Ireland and the United Kingdom, to develop and market this service. Aireon has contracted to pay the Company a fee to host the ADS-B receivers on its constellation, as well as fees for power and data services in connection with the delivery of the air traffic surveillance data. Pursuant to agreements with Aireon, Aireon will pay the Company fees of $200.0 million to host the ADS-B receivers, of which $54.5 million had been paid as of June 30, 2021. Aireon also pays power fees of up to approximately $3.7 million per year under a hosting agreement (the “Hosting Agreement”), as well as data services fees of approximately $19.8 million per year for the delivery of the air traffic surveillance data under a data transmission services agreement (the “Data Services Agreement”). The Aireon ADS-B receivers were activated on an individual basis as the satellite on which the receiver is hosted began carrying traffic. Pursuant to ASU 2016-02, the Company considers the Hosting Agreement an operating lease. The Company recognized $4.0 million of hosting fee revenue for each of the three months ended June 30, 2021 and 2020 and $8.0 million for each of the six months ended June 30, 2021 and 2020. The Company recorded power and data service revenue from Aireon of $5.9 million for each of the three months ended June 30, 2021 and 2020, and $11.7 million and $12.1 million for the six months ended June 30, 2021 and 2020, respectively.

Under two services agreements, the Company also provides Aireon with administrative services and support services, the fees for which are paid monthly. Aireon receivables due to the Company under these two agreements totaled $2.0 million and $2.3 million as of June 30, 2021 and December 31, 2020, respectively.

In December 2018, in connection with Aireon's entry into a debt facility, the Company and the other Aireon investors contributed their respective interests in Aireon into a new holding company, Aireon Holdings LLC, and entered into an amended and restated LLC agreement (the “Amended and Restated Limited Liability Company Agreement”). Aireon Holdings LLC holds 100% of the membership interests in Aireon LLC, which remains the operating entity. At each of June 30, 2021 and December 31, 2020, the Company's fully diluted ownership stake in Aireon Holdings LLC was approximately 35.7%, subject to certain redemption provisions contained in the Amended and Restated Limited Liability Company Agreement. In addition, pursuant to a debt facility for Aireon LLC provided by the Company and the other Aireon investors, the Company will participate pro-rata, based on its fully diluted ownership stake, in an investor bridge loan. As such, in December 2020, the Company invested $0.2 million in the Aireon LLC debt facility, which was subsequently repaid in June 2021. The Company’s maximum commitment under the investor bridge loan is $10.7 million.

Overview of Our Business
We are engaged primarily in providing mobile voice and data communications services using a constellation of orbiting satellites. We are the only commercial provider of communications services offering true global coverage, connecting people, organizations and assets to and from anywhere, in real time. Our unique L-band satellite network provides reliable communications services to regions of the world where terrestrial wireless or wireline networks do not exist or are limited, including remote land areas, open ocean, airways, the polar regions and regions where the telecommunications infrastructure has been affected by political conflicts or natural disasters.
We provide voice and data communications services to businesses, the U.S. and foreign governments, non-governmental organizations and consumers via our upgraded satellite network, which has an architecture of 66 operational satellites with in-orbit and ground spares and related ground infrastructure. We utilize an interlinked mesh architecture to route traffic across the satellite constellation using radio frequency crosslinks between satellites. This unique architecture minimizes the need for ground facilities to support the constellation, which facilitates the global reach of our services and allows us to offer services in countries and regions where we have no physical presence. Our upgraded satellite constellation is compatible with all of our end-user equipment and supports more bandwidth and higher data speeds for our new products, including our Iridium Certus® broadband service.
We sell our products and services to commercial end-users through a wholesale distribution network, encompassing approximately 110 service providers, approximately 275 value-added resellers, or VARs, and approximately 85 value-added manufacturers, or VAMs, who either sell directly to the end user or indirectly through other service providers, VARs or dealers. These distributors often integrate our products and services with other complementary hardware and software and have developed a broad suite of applications for our products and services targeting specific lines of business.
At June 30, 2021, we had approximately 1,616,000 billable subscribers worldwide, representing an increase of 19% from approximately 1,362,000 billable subscribers at June 30, 2020. We have a diverse customer base, with end users in the following lines of business: land mobile, maritime, aviation, Internet of Things, or IoT, hosted payloads and other data services and the U.S. government.
We recognize revenue from both the provision of services and the sale of equipment. Over the past several years, service revenue, including revenue from hosting and data services, has represented an increasing proportion of our revenue, and we expect that trend to continue.

Effects of the COVID-19 Pandemic on Our Business
The COVID-19 pandemic and measures taken in response are currently affecting countries, communities and markets around the world. Like many other businesses, we started to see a slowdown in the final weeks of March 2020 as a result of the widespread economic shutdown. Our distributors have also experienced business and operational restrictions, which continue to limit their ability to visit customers, complete new installations, and close on new business opportunities, particularly internationally. This slowdown extended through 2020 and the first half of 2021, although we have seen significant recovery in some markets, most notably IoT. Other markets, including aviation and maritime, and some international areas continue to suffer significant effects from reduced activity during the pandemic. Aviation, in particular, has started to see recovery but may take years to recover to pre-pandemic levels. In other industries, such as maritime, the effects are significant, but vary greatly
20


by region and business model, and we expect that additional shutdowns will continue to impact our results of operations. The ultimate effects of the COVID-19 pandemic are difficult to assess or predict with certainty at this time but may include additional risks. For further information on the potential effects of the COVID-19 pandemic on our business, financial condition and results of operations, see “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the Securities and Exchange Commission on February 11, 2021, as well as the “Risk Factors” section of this report below.

Material Trends and Uncertainties
Our industry and customer base have historically grown as a result of:
demand for remote and reliable mobile communications services;
a growing number of new products and services and related applications;
a broad wholesale distribution network with access to diverse and geographically dispersed niche markets;
increased demand for communications services by disaster and relief agencies, and emergency first responders;
improved data transmission speeds for mobile satellite service offerings;
regulatory mandates requiring the use of mobile satellite services;
a general reduction in prices of mobile satellite services and subscriber equipment; and
geographic market expansion through the ability to offer our services in additional countries.
Nonetheless, we face a number of challenges and uncertainties in operating our business, including:
our ability to maintain the health, capacity, control and level of service of our satellites;
our ability to develop and launch new and innovative products and services;
changes in general economic, business and industry conditions, including the effects of currency exchange rates;
our reliance on a single primary commercial gateway and a primary satellite network operations center;
competition from other mobile satellite service providers and, to a lesser extent, from the expansion of terrestrial-based cellular phone systems and related pricing pressures;
market acceptance of our products;
regulatory requirements in existing and new geographic markets;
rapid and significant technological changes in the telecommunications industry;
our ability to generate sufficient internal cash flows to repay our debt;
reliance on our wholesale distribution network to market and sell our products, services and applications effectively;
reliance on a global supply chain, including single-source suppliers for the manufacture of most of our subscriber equipment and for some of the components required in the manufacture of our end-user subscriber equipment and our ability to purchase component parts that are periodically subject to shortages resulting from surges in demand, natural disasters or other events, including the COVID-19 pandemic; and
reliance on a few significant customers, particularly agencies of the U.S. government, for a substantial portion of our revenue, as a result of which the loss or decline in business with any of these customers may negatively impact our revenue and collectability of related accounts receivable.

Billable subscriber and ARPU data is not applicable for hosted payload and other data service revenue items.
(3)Commercial broadband service consists of Iridium OpenPort® and Iridium Certus broadband services.
For the three months ended June 30, 2021, total commercial services revenue increased $7.1 million, or 8%, from the prior year period primarily as a result of increases in IoT, broadband, and voice and data revenue. These increases were driven primarily by increases in billable subscribers across all commercial service lines. Commercial IoT revenue increased $4.6 million, or 20%, for the three months ended June 30, 2021, compared to the same period of the prior year. The increase in IoT revenue was driven by a 26% increase in IoT billable subscribers due to continued strength in consumer personal communications devices, as well as the lifting of mobility restrictions that had been imposed due to COVID-19. The subscriber increase effect on revenue was somewhat offset by a 2% reduction in ARPU, primarily due to the increased proportion of personal communication subscribers using lower ARPU plans. This reduction was offset in part by an increase in usage and ARPU by aviation subscribers due to increases in air travel from the prior year quarter. Commercial broadband revenue increased $2.1 million, or 25%, for the three months ended June 30, 2021, compared to the prior year period, driven by an increase in broadband billable subscribers and an increase in ARPU associated with the increase in the mix of subscribers utilizing higher ARPU Iridium Certus® broadband plans. The increases in commercial services revenue were offset in part by a decrease in hosted payload and other service revenue of $1.1 million, or 7%, for the three months ended June 30, 2021, compared to the prior year period. This decrease was due primarily to the recognition of $1.4 million of additional hosting data service revenue in the prior year related to an updated estimate of data service usage based on trends experienced on our hosted payloads.

The annual rate under the EMSS Contract increased from $100.0 million to $103.0 million during the third quarter of 2020.

23


Subscriber Equipment Revenue
Subscriber equipment revenue increased by $1.9 million, or 10%, for the three months ended June 30, 2021 compared to the prior year period, primarily due to an increase in the volume of handset and IoT device sales.

Engineering and support service revenue remained relatively flat at $6.8 million for the three months ended June 30, 2021 compared to the prior year period primarily due to the episodic nature of contract work.

Operating Expenses
Cost of Services (exclusive of depreciation and amortization)
Cost of services (exclusive of depreciation and amortization) includes the cost of network engineering and operations staff, including contractors, software maintenance, product support services and cost of services for government and commercial engineering and support service revenue.
Cost of services (exclusive of depreciation and amortization) increased by $0.3 million, or 1%, for the three months ended June 30, 2021 from the prior year period, primarily as a result of higher maintenance and product support costs.
Cost of Subscriber Equipment
Cost of subscriber equipment includes the direct costs of equipment sold, which consist of manufacturing costs, allocation of overhead, and warranty costs.
Cost of subscriber equipment increased by $0.6 million, or 5%, for the three months ended June 30, 2021 compared to the prior year period primarily due to an increase in handset and IoT device sales, partially offset by a decrease in the volume of L-band transceiver sales.
Research and Development
Research and development expenses increased by $0.2 million, or 10%, for the three months ended June 30, 2021 compared to the prior year period due to increased spending on device-related features for our network.
Selling, General and Administrative
Selling, general and administrative expenses that are not directly attributable to the sale of services or products include sales and marketing costs, as well as employee-related expenses (such as salaries, wages, and benefits), legal, finance, information technology, facilities, billing and customer care expenses.
Selling, general and administrative expenses increased by $2.9 million, or 14%, for the three months ended June 30, 2021 compared to the prior year period, primarily due to higher management incentive costs incurred in the current year quarter as compared to the prior year quarter, which were lower due to the adverse impact of the COVID-19 pandemic. These increases in costs were offset in part by a decrease in legal and other professional fees, as well as a decrease in stock appreciation rights expense in the current year quarter resulting from changes in our stock valuation between the respective reporting periods.
Depreciation and Amortization
Depreciation and amortization expense remained relatively flat as we completed the replacement of our first-generation satellites in February 2019. As the upgraded satellites are the largest proportion of our asset base, we anticipate depreciation and amortization expense to remain relatively consistent from quarter to quarter based on our anticipated capital expenditures.
Other Expense
Interest Expense, Net
Interest expense, net decreased $4.9 million, or 22%, for the three months ended June 30, 2021 compared to the prior year period. The decrease resulted primarily from a decrease of 1.0% in the interest rate as a result of repricing our outstanding debt in January 2021.

24


Income Tax Benefit
For the three months ended June 30, 2021, our income tax benefit was $10.0 million, compared to $4.6 million for the prior year period. The increase in income tax benefit is primarily related to the 2021 discrete state tax benefit associated with a state apportionment change. This was offset in part by a decrease in loss before income taxes compared to the prior year.
Net Income (Loss)
Net income was $3.8 million for the three months ended June 30, 2021, compared to a net loss of $12.4 million for the prior year period. The change was primarily a result of a $5.8 million increase in operating income, the $5.4 million increase in the income tax benefit as described above, and the $4.9 million decrease in interest expense, net.

(3)Commercial broadband service consists of Iridium OpenPort and Iridium Certus broadband services.
For the six months ended June 30, 2021, total commercial services revenue increased $6.7 million, or 4%, from the prior year period primarily as a result of increases in IoT and broadband revenue primarily driven by increases in billable subscribers. Commercial IoT revenue increased $5.6 million, or 12%, for the six months ended June 30, 2021, compared to the prior year period. The increase in IoT revenue was driven by a 26% increase in IoT billable subscribers due to continued strength in personal communications devices, as well as the lifting of mobility restrictions that had been imposed due to COVID-19. The subscriber increase effect on revenue was somewhat offset by a 9% reduction in ARPU, primarily due to the increased proportion of personal communication subscribers using lower ARPU plans. Commercial broadband revenue increased $2.9 million, or 17%, for the six months ended June 30, 2021, compared to the prior year period, due primarily to the increase in broadband billable subscribers and an increase in ARPU associated with the increase in the mix of subscribers utilizing higher ARPU Iridium Certus broadband plans. These increases were offset by a decrease in hosted payload and other service revenue of $2.5 million, or 8%, for the six months ended June 30, 2021, compared to the prior year period. This decrease was due to a data billing settlement that resulted in recognition of $1.3 million in the prior year period that did not recur in the current year, plus the recognition of an additional $1.4 million of additional hosting data service revenue in the prior year due to an updated estimate of data service usage based on trends experienced on our hosted payloads.

Operating Expenses
Cost of Services (exclusive of depreciation and amortization)
Cost of services (exclusive of depreciation and amortization) increased by $1.5 million, or 3%, for the six months ended June 30, 2021 from the prior year period, primarily as a result of higher maintenance and product support costs.
Cost of Subscriber Equipment
Cost of subscriber equipment increased by $1.4 million, or 6%, for the six months ended June 30, 2021 compared to the prior year period primarily due to an increase in the volume of IoT and handset device sales, partially offset by a decrease in the volume of L-band transceiver device sales.
Research and Development
Research and development expenses increased by $0.5 million, or 11%, for the six months ended June 30, 2021 compared to the prior year period due to increased spending on devices and related features for our network.
Selling, General and Administrative
Selling, general and administrative expenses increased by $4.7 million, or 11%, for the six months ended June 30, 2021 compared to the prior year period, primarily due to higher management incentive costs incurred in the current year period as compared to the prior year period, which were lower due to the adverse impact of the COVID-19 pandemic. These increases in costs were offset in part by a decrease in legal fees.
Depreciation and Amortization
Depreciation and amortization expense remained relatively flat as we completed the replacement of our first-generation satellites in February 2019. As the upgraded satellites are the largest proportion of our asset base, we anticipate depreciation and amortization expense to remain relatively consistent from quarter to quarter based on our anticipated capital expenditures.
Other Expense
Interest Expense, Net
Interest expense, net decreased $8.6 million for the six months ended June 30, 2021 compared to the prior year period. In 2021, we had a lower weighted average effective interest rate as a result of our debt refinancing in 2020 as well as our repricing in 2021. The 2020 refinancing reduced our overall outstanding principal balance and the 2021 repricing reduced our interest rate by 1.0%. The decrease in interest expense was offset by $3.6 million of fees we paid in the current year period in connection with the repricing.
Loss on Extinguishment of Debt
We did not record a loss on extinguishment of debt for the six months ended June 30, 2021, compared to a $30.2 million loss on extinguishment of debt recorded for the six months ended June 30, 2020. The loss on extinguishment of debt in 2020 resulted from the write off of unamortized debt issuance costs when we closed on an additional $200.0 million under our Term Loan in February 2020 and used the proceeds, together with cash on hand, to prepay all of the indebtedness outstanding under our senior unsecured notes, including premiums for early prepayment.

Income Tax Benefit
For the six months ended June 30, 2021, our income tax benefit was $18.6 million, compared to income tax benefit of $17.3 million for the prior year period. The increase in income tax benefit is primarily related the 2021 discrete state tax benefit associated with a state apportionment change and a greater stock compensation tax deduction which resulted from an increase in the value of both stock options exercised and vested restricted stock units. This was offset in part by a decrease in loss before income taxes compared to the prior year plus an increase in the valuation allowance for state net operating losses.
Net Loss
Net loss was $1.4 million for the six months ended June 30, 2021, compared to $44.1 million for the prior year period. The change primarily resulted from the $30.2 million decrease in loss on extinguishment of debt and the $8.6 million decrease in interest expense, net, as well as the $3.0 million increase in operating income.

Liquidity and Capital Resources

In November 2019, we issued our $1,450.0 million term loan with Deutsche Bank AG, or the Term Loan, with an accompanying $100.0 million revolving loan, or the Revolving Facility, or, collectively, the Credit Agreement.

In February 2020, we issued an additional $200.0 million under our Term Loan and used the proceeds and approximately $183.5 million of cash on hand to repay in full all of the indebtedness outstanding under our senior unsecured notes, including premiums for early repayment.

In January 2021, we repriced all borrowings outstanding under our Term Loan. The Term Loan now bears interest at an annual rate of LIBOR plus 2.75%, with a 1.00% LIBOR floor. All other terms remain the same, including maturity in November 2026. To reprice the Term Loan, we incurred additional financing costs of $3.6 million.

As of June 30, 2021, we reported an aggregate balance of $1,628.8 million in borrowings under the Term Loan, before $22.1 million of net deferred financing costs, for a net principal balance of $1,606.7 million outstanding in our condensed consolidated balance sheet. We have not drawn on our Revolving Facility.

Our Term Loan contains no financial maintenance covenants. With respect to the Revolving Facility, we are required to maintain a consolidated first lien net leverage ratio 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. We were in compliance with all covenants under the Credit Agreement as of June 30, 2021.

The Credit Agreement restricts our 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 trailing twelve months of earnings before interest, taxes, depreciation and amortization, or 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 our excess cash flow (as defined in the Credit Agreement), which is phased out based on achievement and maintenance of specified leverage ratios. Our mandatory excess cash flow prepayment, as specified in the Credit Agreement, was calculated to be $12.7 million as of December 31, 2020. Lenders have the right to decline payment. As such, we paid $4.7 million to lenders who did not decline payment in May 2021. This amount counts towards our required quarterly principal payments. The Credit Agreement permits repayment, prepayment, and repricing transactions.

As of June 30, 2021, our total cash and cash equivalents balance was $213.4 million, our marketable securities balance was $6.0 million, and we had $100.0 million of borrowing availability under our Revolving Facility. In addition to the Revolving Facility, our principal sources of liquidity are cash, cash equivalents and internally generated cash flows. Our principal liquidity requirements over the next twelve months are primarily principal and interest on the Term Loan, working capital and potential share repurchases under the share repurchase program described in Note 8.

We believe our liquidity sources will provide sufficient funds for us to meet our liquidity requirements for at least the next 12 months.

Cash Flows
The following table summarizes our cash flows:
 Six Months Ended June 30, 
 20212020Change
 (In thousands)
Cash provided by operating activities$125,967 $104,532 $21,435 
Cash used in investing activities$(18,937)$(18,655)$(282)
Cash used in financing activities$(131,222)$(189,083)$57,861 

Cash Flows Provided by Operating Activities

Net cash provided by operating activities for the six months ended June 30, 2021 increased by $21.4 million from the prior year period. Net loss, as adjusted for non-cash activities, improved by $15.0 million over the prior year, as a result of improved profitability. Net cash from operating activities also increased related to working capital changes of approximately $6.4 million. Working capital increased primarily as a result of accrued expenses and other current liabilities, which decreased due to a decreased payout on management incentives due to the COVID-19 impact on 2020 results. Working capital also increased related to a decrease in the interest payable compared to the prior year. These increases were offset by timing of customer collections and payments to vendors.

Cash Flows Used in Investing Activities

Net cash used in investing activities for the six months ended June 30, 2021 increased slightly over the prior year. We continue to expect our capital expenditures to average approximately $40.0 million per year until 2029.
Cash Flows Used in Financing Activities
Net cash used in financing activities for the six months ended June 30, 2021 decreased by $57.9 million compared to the prior year period primarily due to lower net principal payments as we utilized our cash to pay down additional debt in the prior year. The combination of principal prepayment on the senior unsecured notes and additional borrowings under the Term Loan resulted in net payments of $185.6 million for the six months ended June 30, 2020 compared to $8.8 million for 2021. This decrease in cash outflows was partially offset by $122.5 million used in 2021 for the repurchase of our common stock. See Note 5 to our condensed consolidated financial statements included in this report for further discussion of our indebtedness and Note 8 for further information on our stock repurchase program.

Off-Balance Sheet Arrangements

We do not currently have, nor have we had in the last three years, any relationships with unconsolidated entities or financial partnerships, such as entities referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Seasonality

Our results of operations have been subject to seasonal usage changes for commercial customers, and our results will be affected by similar seasonality going forward. March through October are typically the peak months for commercial voice services revenue and related subscriber equipment sales. U.S. government revenue and commercial IoT revenue have been less subject to seasonal usage changes.
Critical Accounting Policies and Estimates
The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. The preparation of these financial statements requires the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, useful lives of property and equipment, long-lived assets and other intangible assets, deferred financing costs, income taxes, stock-based compensation, and other estimates. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.
29


There have been no changes to our critical accounting policies from those described in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC on February 11, 2021.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We have an outstanding aggregate balance of $1,628.8 million under the Term Loan as of June 30, 2021. We have executed a long-term interest rate swap, or the Swap, for $1,000.0 million of the Term Loan, through November 2021. For the portion of the Term Loan not covered under the Swap, we pay interest at an annual rate equal to the London Interbank Offered Rate, or LIBOR, plus 2.75%, with a 1.0% LIBOR floor, which will, accordingly, subject us to interest rate fluctuations in future periods. A one-half percentage point increase or decrease in the LIBOR would not have had a material impact on our interest cost for the period.

We have no borrowings under our Revolving Facility as of June 30, 2021. Accordingly, although the Revolving Facility bears interest at LIBOR plus 3.75%, without a LIBOR floor, if and as drawn, we were not exposed to fluctuations in interest rates with respect to our Revolving Facility.

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, as well as accounts receivable. We maintain our cash and cash equivalents with financial institutions with high credit ratings and at times maintain the balance of our deposits in excess of federally insured limits. The majority of our cash is swept nightly into a money market fund invested in U.S. treasuries, Agency Mortgage Backed Securities and/or U.S. government guaranteed debt. Accounts receivable are due from both domestic and international customers. We perform credit evaluations of our customers’ financial condition and record reserves to provide for estimated credit losses. Accounts payable are owed to both domestic and international vendors.

ITEM 4.CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer, who is our principal executive officer, and our chief financial officer, who is our principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as of the end of the period covered by this report. In evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.

Based on this evaluation, our chief executive officer and our chief financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.
Changes in Internal Control Over Financial Reporting
During the quarter ended June 30, 2021, there were no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A.     RISK FACTORS.

Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. In addition to the other information set forth in this quarterly report on Form 10-Q, you should carefully consider the factors described in “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the Securities and Exchange Commission on February 11, 2021, as supplemented by the following updated risk factor.
We rely on a limited number of key vendors for supply of equipment, components and services; the loss of any such supplier, or shortages experienced by such suppliers, could cause us to incur additional costs and delays in the production and delivery of our products, which could reduce the sales of those products and use of the related services.
We currently rely on two manufacturers of our devices, including our mobile handsets, L-band transceivers and SBD devices. We also utilize sole source suppliers for some of the component parts of our devices. If any of our suppliers were to terminate its relationship with us, we may not be able to find a replacement supplier in a timely manner, at an acceptable price or at all.
Further, our manufacturers and suppliers may cease production of our components or products or become capacity-constrained, or could face financial difficulties as a result of a surge in demand, a natural disaster or other event, including the impacts of the COVID-19 pandemic. For example, several of our suppliers are experiencing production delays as a result of the global silicon chip shortage. As a result, we expect to experience delays in fulfilling some product orders and are evaluating replacement components and product changes, which would increase our costs and reduce our sales of those products and future use of the related services.
Any future delay in production or delivery of our products or components by our suppliers could similarly adversely affect our business. Even if we are able to replace or supplement sole source or other component suppliers, there could be a substantial period of time in which our products would not be available; any new relationship may involve higher costs and delays in development and delivery, and we may encounter technical challenges in successfully replicating the manufacturing processes. If our manufacturers or suppliers terminate their relationships with us, fail to provide equipment or services to us on a timely basis, or fail to meet our performance expectations, we may be unable to provide products or services to our customers in a competitive manner, which could in turn negatively affect our financial results and our reputation.
