**COGENT COMMUNICATIONS HOLDINGS, INC., AND SUBSIDIARIES**

**NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**1. Description of the business:**

**Reorganization and merger**

On May 15, 2014, pursuant to the Agreement and Plan of Reorganization by and among Cogent Communications Group, Inc. (now Cogent Communications Group, LLC), a Delaware corporation ("Group"), Cogent Communications Holdings, Inc., a Delaware corporation ("Holdings"), and Cogent Communications Merger Sub, Inc., a Delaware corporation, Group adopted a new holding company organizational structure whereby Group is now a wholly owned subsidiary of Holdings. Holdings is a "successor issuer" to Group pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). References to the "Company" for events that occurred prior to May 15, 2014 refer to Cogent Communications Group, Inc. (now Cogent Communications Group, LLC) and its subsidiaries, and on and after May 15, 2014, the "Company" refers to Cogent Communications Holdings, Inc. and its subsidiaries. Cogent Communications, LLC (formerly Cogent Communications, Inc.) is wholly owned by Group, Cogent Fiber LLC (formerly Sprint Communications Company LP) is indirectly wholly owned by Holdings, and the vast majority of the Company's assets are held by, contractual arrangements are executed by, and operations are conducted by, Cogent Fiber LLC and Cogent Communications, LLC.

**Description of business**

The Company is a facilities-based provider of low-cost, high-speed Internet access, private network services, optical wavelength and optical transport services and data center colocation space and power. The Company operates two networks: an IP Network specifically designed and optimized to transmit packet routed data and a wavelength network designed to provide optical wave and transport services ("Optical Wave Network"). The Company delivers its services primarily to businesses, large and small, communications service providers and other bandwidth-intensive organizations in 57 countries across North America, Europe, Asia, South America, Oceania and Africa. The Company is a Delaware corporation and is headquartered in Washington, DC.

The Company offers on-net Internet access services exclusively through its own facilities, which run from its IP Network to its customers' premises. The Company offers its on-net services to customers located in buildings that are physically connected to its IP Network. As a result, the Company is not dependent on local telephone companies or cable TV companies to serve its customers for its on-net Internet access and private network services. The Company's on-net service consists of high-speed Internet access and private network services offered at speeds ranging from 100 megabits per second to 400 gigabits per second.

The Company provides its on-net Internet access and private network services to its corporate, net-centric and enterprise customers. The Company's corporate customers are located in multi-tenant office buildings that typically include law firms, financial services firms, advertising and marketing firms, as well as health care providers, educational institutions and other professional services businesses. The Company's net-centric customers include bandwidth-intensive users that leverage its network either to deliver content to end users or to provide access to residential or commercial Internet users. Content delivery customers include over the top media service providers, content delivery networks, web hosting companies, and commercial content and application software providers. The Company's net-centric customers include access networks comprised of other Internet Service Providers, telephone companies, mobile phone operators and cable television companies that collectively provide internet access to a substantial number of broadband subscribers and mobile phone subscribers across the world. These net-centric customers generally receive the Company's services in carrier neutral colocation facilities and in the Company's own data centers. The Company operates data centers throughout North America and Europe that allow its customers to collocate their equipment and access the Company's network.

Page **6** of **46**

[**Table of Contents**](#TOC)

In addition to providing on-net services, the Company provides Internet access and private network services to customers that are not located in buildings directly connected to its network. The Company provides these off-net services primarily to corporate customers using other carriers' circuits to provide the "last mile" portion of the link from the customers' premises to the Company's network. The Company also provides certain non-core services that resulted from acquisitions, including the acquisition of Sprint Communications, now called Cogent Fiber LLC (as discussed below). The Company continues to support but does not actively sell these non-core services.

Following the Company's acquisition of Cogent Fiber LLC and pursuant to intercompany arrangements between Cogent Fiber LLC and the Company for use of the acquired Cogent Fiber LLC network, the Company began to provide optical wavelength services and optical transport services over its Optical Wave Network that is generally independent of the Company's IP Network. The Company is selling these wavelength services to its existing customers, customers of Cogent Fiber LLC and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure.

Additionally, the customers of the Cogent Fiber Business (as defined below) include a number of companies larger than the Company's historical customer base. In connection with the acquisition of Cogent Fiber LLC, the Company expanded selling services to these larger "Enterprise" customers.

**Accounting Standards Not Yet Adopted**

In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update No. 2024-03, *Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses*, ("ASU 2024-03"), which requires a public business entity to disclose additional information about specific expense categories in the notes to financial statements on an annual and interim basis. The amendments are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. A public entity should apply the amendments either prospectively to financial statements issued for reporting periods after the effective date of the ASU or retrospectively to any or all prior periods presented in the financial statements. The Company will not early adopt ASU 2024-03 and is in the process of evaluating the impact on its consolidated financial statements from the adoption of ASU 2024-03.

**Acquisition of Cogent Fiber Business**

On September 6, 2022, Cogent Infrastructure, Inc. (now Cogent Infrastructure, LLC), a Delaware corporation and a direct wholly owned subsidiary of the Company (the "Buyer" or "Cogent Infrastructure"), entered into a Membership Interest Purchase Agreement (the "Purchase Agreement") with Sprint Communications LLC, a Kansas limited liability company ("Sprint Communications") and an indirect wholly owned subsidiary of T-Mobile US, Inc., a Delaware corporation ("T-Mobile"), and Sprint LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of T-Mobile (the "Seller"), pursuant to which the Company acquired the U.S. long-haul fiber network (including the non-U.S. extensions thereof) of Sprint Communications (now Cogent Fiber LLC) and its subsidiaries (the "Cogent Fiber Business"). Pursuant to the Purchase Agreement, the Company purchased from the Seller all of the issued and outstanding membership interests (the "Purchased Interests") of Wireline Network Holdings LLC, a Delaware limited liability company that, following an internal restructuring and divisive merger, held Sprint Communications' assets and liabilities relating to the Cogent Fiber Business (such transactions contemplated by the Purchase Agreement, collectively, the "Transaction"). The Purchase Agreement included customary representations, warranties, indemnities and covenants, including regarding the conduct of the Cogent Fiber Business prior to the closing of the Transaction (the "Closing"). In addition, the Closing was subject to customary closing conditions, including the receipt of certain required regulatory approvals and consents.

The Company believes it is in a unique position to monetize the Cogent Fiber Business and its network and management expects to achieve significant cost reduction synergies and revenue synergies from the Transaction.

[**Table of Contents**](#TOC)

**Purchase Price**

The Transaction closed on May 1, 2023 (the "Closing Date"). On the Closing Date, the Buyer consummated the Transaction pursuant to the terms of the Purchase Agreement, providing a purchase price of $1 payable to the Seller for the Purchased Interests, subject to customary adjustments, including working capital (the "Working Capital Adjustment"), as set forth in the Purchase Agreement. As consideration for the Purchased Interests, the Working Capital Adjustment (primarily related to acquired cash and cash equivalents of an estimated $43.4 million at the Closing Date in order to fund the international operations of the Cogent Fiber Business) resulted in the Buyer making a payment to the Seller of $61.1 million on the Closing Date. During the third quarter of 2023, an additional Working Capital Adjustment of $5.0 million was accrued due to the Seller. The final determination of the Working Capital Adjustment (which included the Short-term Lease Payment below) was completed in April 2024, and the Company paid the Seller $5.0 million for the remaining Working Capital Adjustment.

*Short-term lease payment*

The Purchase Agreement also provides for a payment of $28.1 million ($19.8 million net of discount) from the Seller to the Buyer related to acquired short-term operating lease obligations (the "Short-term Lease Payment"). The Short-term Lease Payment will be paid from the Seller to the Company in four equal payments in months 55 to 58 after the Closing Date. The final determination of the Short-term Lease Payment was completed in April 2024. The Short-term Lease Payment was recorded at its present value resulting in a discount of $8.4 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment. During the third quarter of 2023, the Short-term Lease Payment was reduced by $4.8 million and in the first quarter of 2024, the Short-term Lease Payment was reduced by an additional $17.0 million, net of discount of $7.2 million. Including the cumulative impact of these adjustments, the amortization of the discount resulted in interest income of $0.5 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively.

*IP Transit Services Agreement*

On the Closing Date, Cogent Communications, Inc. (now Cogent Communications, LLC), and T-Mobile USA, Inc., a Delaware corporation and direct subsidiary of T-Mobile ("TMUSA"), entered into an agreement for IP transit services ("IP Transit Services Agreement"), pursuant to which TMUSA will pay an affiliate of the Company an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments of $29.2 million per month during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments of $8.3 million per month over the subsequent 42 months. Under the IP Transit Services Agreement. TMUSA paid the Company $25.0 million both during the three months ended March 31, 2026 and 2025.

The Company accounted for the Transaction as a business combination under ASC Topic 805 *Business Combinations* ("ASC 805"). The Company evaluated what elements are part of the business combination and the consideration exchanged to complete the acquisition. Under ASC 805, the Company has concluded that the $700.0 million of payments to be made represent consideration received from T - Mobile to complete the acquisition of a distressed business. The Company also evaluated whether the IP Transit Services Agreement was in the scope of ASU No. 2014 - 09 *Revenue from Contracts with Customers* ("ASC 606"). The Company has concluded that T - Mobile did not represent a "customer" as defined by ASC 606, the stated contract price did not represent consideration for services to be delivered, and the transaction did not satisfy the definition of revenue, which excluded this arrangement from the scope of ASC 606. As a result, and considering statements made by T - Mobile, the IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount of $79.6 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment. The amortization of the discount resulted in interest income of $3.1 million and $4.7 million during the three months ended March 31, 2026 and 2025, respectively.

*Acquired Property & Equipment*

In connection with the Transaction, the Company acquired property and equipment of $965.7 million. This was primarily comprised of the legacy Sprint network and consisted of optical fiber, related equipment, and owned real estate that were valued using a combination of cost and market approaches. Management intends to operate the acquired business; however, management valued these assets using factors that represent an orderly liquidation value, to approximate the highest and best use of assets acquired in a distressed business.

Page **8** of **46**

[**Table of Contents**](#TOC)

The estimated fair value of the optical fiber on the Closing Date was $369.2 million. The valuation required the estimation of the total replacement cost per mile of fiber and a factor to reflect the orderly liquidation value. There is no active market data for these assumptions and these assumptions are inherently subjective. Market participants could have differing views on these assumptions, which could result in a materially different fair value of the optical fiber.

*Acquired Leases*

The Company acquired a portfolio of lease arrangements for the lease of dark fiber, rights-of-way and facilities. In accordance with ASC 805 and ASC Topic 842 *Leases*, the acquired leases are accounted for as if the leases were new at the acquisition date, however, the Company retains the lease classification from the Seller. The Company followed its historical policies with respect to evaluating the renewal periods of the acquired leases and estimating the incremental borrowing rate.

The Company also evaluated the leases for unfavorable terms and recorded an adjustment for unfavorable market terms of $157.2 million that was valued using the income approach. Unfavorable lease liabilities are presented net of the corresponding right-of-use assets.

*Acquired Intangible Assets*

Intangible assets acquired include $458.0 million of Internet Protocol version 4 ("IPv4") addresses and $16.0 million of acquired customer relationships. The acquired customer relationships have an estimated useful life of nine years, and the estimated fair value was determined using a market-based income approach. Amortization expense was $0.4 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively. Future amortization expense of the customer relationships is $1.8 million per year for six years.

The fair value measurement of the IPv4 addresses was based on recent auction prices and a factor to incorporate the uncertainty for how the market for IPv4 addresses will function in the future. The Company believes that the IPv4 address asset has an indefinite useful life and is not being amortized. The Company evaluates the IPv4 address asset for impairment on the first day of the fourth quarter, or more frequently if events or changes in circumstances indicate that the carrying amount may not be recoverable. In performing the impairment assessment, the Company may first evaluate qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. Upon consideration of relevant factors, the Company concluded that it was not more-likely-than-not that impairment was present, and therefore, a quantitative impairment assessment was not required. There was no impairment recorded during the period from May 1, 2023 through March 31, 2026.

**Basis of presentation**

The accompanying unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, the unaudited 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. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. While the Company believes that the disclosures are adequate to not make the information misleading, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in its annual report on Form 10-K for the year ended December 31, 2025. Certain prior year amounts have been reclassified to conform to current year presentation.

The accompanying unaudited condensed consolidated financial statements include all wholly owned subsidiaries. All inter-company accounts and activity have been eliminated.

*Use of estimates*

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of

Page **9** of **46**

[**Table of Contents**](#TOC)

the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates.

*Financial instruments*

At March 31, 2026 and December 31, 2025, the carrying amount of cash and cash equivalents, restricted cash, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses approximated fair value because of the short-term nature of these instruments. The Company measures its cash equivalents and restricted cash at amortized cost, which approximates fair value based upon quoted market prices (Level 1).

Based upon recent trading prices (Level 2—market approach) at March 31, 2026:

● The fair value of the Company's $450.0 million aggregate principal amount of 7.00% Senior Unsecured Notes due 2027 (the "2027 Notes") was $444.4 million;

● The fair value of the Company's $300.0 million aggregate principal amount of 7.00% Senior Unsecured Mirror Notes due 2027 (the "2027 Mirror Notes") was $296.3 million;

● The fair value of the Company's $600.0 million aggregate principal amount of 6.50% Senior Secured Notes due 2032 (the "2032 Notes") was $516.0 million; and

● The fair value of the Company's $380.4 million aggregate principal amount of secured IPv4 notes (the "IPv4 Notes") was $389.8 million.

*Restricted cash*

Restricted cash includes amounts held in segregated bank accounts by the Company's clearing broker as margin in support of the Company's Swap Agreement, as discussed in Note 3, and was $4.1 million as of December 31, 2025. The Swap Agreement was settled in February 2026. Restricted cash related to the IPv4 Notes, as discussed in Note 3, was $39.0 million as of March 31, 2026 and $52.5 million as of December 31, 2025. Additional cash may be further restricted under the provisions of the Company's IPv4 Note indenture. The Company does not use derivative financial instruments for trading purposes.

*Gross receipts taxes, universal service fund and other surcharges*

Revenue recognition standards include guidance relating to taxes or surcharges assessed by a governmental authority that are directly imposed on a revenue-producing transaction between a seller and a customer and may include, but are not limited to, gross receipts taxes, excise taxes, Universal Service Fund fees and certain state regulatory fees. Such charges may be presented gross or net based upon the Company's accounting policy election. The Company records certain excise taxes and surcharges on a gross basis and includes them in its revenue and network operations expense. Excise taxes and surcharges billed to customers and recorded on a gross basis (as service revenue and network operations expense) were $19.5 million and $20.2 million for the three months ended March 31, 2026 and 2025, respectively.

*Basic and diluted net loss per common share*

Basic net income or net loss per share ("EPS") excludes dilution for common stock equivalents and is computed by dividing net income or net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS is based on the weighted-average number of shares of common stock outstanding during each period, adjusted for the effect of dilutive common stock equivalents. Shares of restricted stock are included in the computation of basic EPS as they vest and are included in diluted EPS, to the extent they are dilutive, determined using the treasury stock method.

*Revenue recognition*

The Company recognizes revenue under ASU No. 2014 - 09, *Revenue from Contracts with Customers* ("ASC 606"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Fees billed in connection with customer installations are recorded as deferred revenue. Installation fees for contracts with terms longer than month-to-month are recognized over the contract term. The Company recognizes revenue over the estimated average customer life for installation fees associated with month-to-month contracts. To the extent a customer contract is terminated prior to its contractual end, the customer is subject to termination fees. The Company vigorously seeks payment of these termination fees. The Company recognizes revenue for termination fees as they are collected.

*Lessor Accounting*

The Company is a lessor for leases of owned dark fiber acquired in connection with the Transaction, that have contract terms that are accounted for as operating leases. These transactions are generally structured as indefeasible-right-of use agreements ("IRUs"), which are the exclusive right to use specified fibers for a specified term, typically 20 - 25 years. Cash consideration received on transfers of dark fiber, including upfront installation fees, is recognized on a straight-line basis to service revenue over the term of the agreement. Lease income is included in service revenue in the condensed consolidated statements of comprehensive (loss) income.

*Leases*

In February 2016, the FASB issued ASU No. 2016-02, *Leases* ("ASU 2016-02"). ASU 2016-02 replaced most existing lease accounting guidance. The operating lease liability under ASU 2016-02 is not considered a liability under the consolidated leverage ratio calculations in the indentures governing the Company's senior unsecured and senior secured note obligations. The Company has made an accounting policy election to not apply the recognition requirements of ASU 2016-02 to its short-term leases-leases with a term of one year or less. The Company has also elected to apply certain practical expedients under ASU 2016-02 including not separating lease and non-lease components on its finance and operating leases.

*Operating leases and finance leases*

The Company has entered into lease agreements with numerous providers of dark fiber under IRUs. These IRUs typically have initial terms of 15-20 years and include renewal options after the initial lease term. The majority of these leases are finance leases. The Company also leases office space, rights-of-way, dark fiber and certain data center facilities under operating leases. Right-of-use assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent its obligation to make lease payments under the lease.

As of March 31, 2026, the Company had committed to additional IRU agreements totaling $105.5 million in future payments to be paid over periods of up to 20 years. These obligations begin when the related fiber is accepted, which is generally expected to occur in the next 12 months.

The future minimum payments under the Company's operating lease and finance lease agreements are as follows (in thousands):

*Allowance for credit losses*

The Company estimates credit losses expected over the life of its trade receivables based on historical information combined with current conditions that may affect a customer's ability to pay and reasonable and supportable forecasts. While the Company uses various credit quality metrics, it primarily monitors collectability by reviewing the duration of collection pursuits on its delinquent trade receivables. Based on the Company's experience, the customer's delinquency status is the strongest indicator of the credit quality of the underlying trade receivables, which is analyzed monthly.

*Asset Retirement Obligations*

In accordance with ASC 410, the Company has not recorded an asset retirement obligation related to restoration obligations for the removal of optical fiber because a settlement date for which to remove the fiber is indeterminable and therefore a reasonable estimation of fair value cannot be made.

*Issuance of $600.0 million principal amount of 2032 Notes and redemption of the 2026 Notes*

On June 17, 2025 (the "2032 Notes Closing Date"), Group and Cogent Finance, Inc. (the "Co-Issuer" and, together with Group, the "Issuers"), two wholly owned subsidiaries of the Company, completed an offering of $600.0 million aggregate principal amount of 2032 Notes for issuance in a private placement not registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"). The 2032 Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers in an unregistered offering pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in transactions outside the United States in compliance with Regulation S under the Securities Act. The 2032 Notes are due on July 1, 2032, and bear interest at a rate of 6.50% per year. Interest on the 2032 Notes is paid semi - annually on January 1 and July 1 of each year beginning on January 1, 2026. The 2032 Notes were issued in connection with the redemption of the Company's $500.0 million 3.50% Senior Secured Notes due to mature in May 2026 (the "2026 Notes").

The net proceeds from the offering were $597.8 million after deducting offering expenses. On June 4, 2025, the Issuers issued a notice of conditional full redemption to holders of all of the then-outstanding 2026 Notes, specifying the 2032 Notes Closing Date as the redemption date. On the 2032 Notes Closing Date, Group used $507.3 million of the net proceeds from the offering to redeem in full, and satisfy and discharge the Issuers' obligations under, the 2026 Notes. The obligations under the 2026 Notes included the $500.0 million principal amount, a $5.0 million make-whole payment and $2.2 million of accrued interest. As a result of the redemption of the 2026 Notes, the Company incurred a loss on debt extinguishment and redemption of $5.6 million. Group expects to use the remainder of the net proceeds for general corporate purposes and/or to make special or recurring dividends to the Company.

The 2032 Notes were issued pursuant to, and are governed by, an indenture, dated June 17, 2025 (the "2032 Notes Indenture"), among the Issuers, the Company, the other guarantors named therein and Wilmington Trust, National Association, as trustee and collateral agent. The 2032 Notes are jointly and severally guaranteed (the "2032 Notes Subsidiary Guarantees") on a senior secured basis by each of Group's existing and future material domestic subsidiaries (other than the Co-Issuer), subject to certain exceptions (collectively, the "2032 Notes Subsidiary Guarantors"). In addition, the 2032 Notes are guaranteed (together with the 2032 Notes Subsidiary Guarantees, the "Guarantees") on a senior unsecured basis by the Company (together with the 2032 Notes Subsidiary Guarantors, the "Guarantors"). However, the Company is not subject to the covenants under the 2032 Notes Indenture. Under certain circumstances, the 2032 Notes Guarantors may be released from these 2032 Notes Guarantees without the consent of the holders of the 2032 Notes.

The 2032 Notes and the 2032 Notes Subsidiary Guarantees are the Issuers' and the 2032 Notes Subsidiary Guarantors' senior secured obligations, secured by a first-priority lien on substantially all of the Issuers' and the 2032 Notes Subsidiary Guarantors' assets, subject to certain exceptions, exclusions, limitations and permitted liens. The 2032 Notes and the 2032 Notes Subsidiary Guarantees are effectively senior to any of the Issuers' and the Subsidiary Guarantors' existing and future senior unsecured indebtedness, including the 2027 Notes and 2027 Mirror Notes (together, the "Existing Unsecured 2027 Notes"), and future indebtedness secured by liens on the collateral securing the 2032 Notes that are junior to the liens on the collateral securing the 2032 Notes, in each case, to the extent of the value of the collateral securing the 2032 Notes. Without giving effect to collateral arrangements, the 2032 Notes and the 2032 Notes Subsidiary Guarantees rank *pari passu* in right of payment with all of the Issuers' and the 2032 Notes Subsidiary Guarantors' existing and future senior indebtedness that is not subordinated in right of payment to the 2032 Notes or the 2032 Notes Subsidiary Guarantees, including the Existing Unsecured 2027 Notes, and are effectively subordinated to any of the Issuers' and the 2032 Notes Subsidiary Guarantors' indebtedness that is secured by assets that do not constitute collateral or that is secured by liens on the collateral securing the 2032 Notes that are senior to the liens securing the 2032 Notes, in each case, to the extent of the value of the collateral securing such indebtedness. In addition, the 2032 Notes and the 2032 Notes Subsidiary Guarantees rank contractually senior in right of payment to all of the Issuers' and the 2032 Notes Subsidiary Guarantors' subordinated indebtedness and are structurally subordinated to any existing and future indebtedness and other liabilities of Group's non-guarantor subsidiaries (other than the Co-Issuer). The Company's guarantee is its senior unsecured obligation and is effectively subordinated to the Company's secured indebtedness to the extent of the value of the collateral securing such indebtedness. Without giving effect to collateral arrangements, the Company's guarantee ranks *pari passu* in right of payment with all of the Company's existing and future senior indebtedness, including its guarantee of the Existing Unsecured 2027 Notes, and contractually senior in right of payment to all of the Company's future subordinated indebtedness. The Company's guarantee is structurally subordinated to any existing and future indebtedness and other liabilities of the Company's subsidiaries that are neither the Issuers nor a 2032 Notes Subsidiary Guarantor, including the secured IPv4 Notes.

The 2032 Notes bear interest at a rate of 6.50% per annum. Interest began to accrue on the 2032 Notes on June 17, 2025 and will be paid semi-annually in arrears on January 1 and July 1 of each year, commencing January 1, 2026, to the persons who are registered holders of the 2032 Notes at the close of business on the December 15 or June 15 immediately preceding the applicable interest payment date. Unless earlier redeemed or repurchased, the 2032 Notes will mature on July 1, 2032.

The Issuers may redeem some or all of the 2032 Notes at any time prior to July 1, 2028 at a price equal to 100% of the principal amount of the 2032 Notes, plus a "make-whole" premium as set forth in the 2032 Notes Indenture, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption. The Issuers may also redeem up to 40% of the principal amount of the 2032 Notes using proceeds of certain equity offerings completed prior to July 1, 2028 at a redemption price equal to 106.500%, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption, subject to certain exceptions. Thereafter, the Issuers may redeem the 2032 Notes, in whole or in part, at a redemption price ranging from 103.250% of the aggregate principal amount of the 2032 Notes redeemed to par (depending on the year), in each case, as set forth in the 2032 Notes Indenture, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption.

If Group undergoes specific kinds of changes in control accompanied by certain ratings events, the Issuers will be required to offer to repurchase the 2032 Notes from holders at a price equal to 101.0% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase. Additionally, if Group or any of its restricted subsidiaries sells assets and does not apply the proceeds from such sale in a certain manner or certain other events have not occurred, under certain circumstances, the Issuers will be required to use the net proceeds to make an offer to purchase the 2032 Notes at an offer price in cash equal to 100.0% of the principal amount of the 2032 Notes, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

In connection with any offer to purchase all or any of the 2032 Notes (including a change of control offer, asset sale, offer or any tender offer), if holders of not less than 90.0% of the aggregate principal amount of the outstanding 2032 Notes validly tender their 2032 Notes, the Issuers or a third party are entitled to redeem any remaining 2032 Notes at the price paid to each holder.

The 2032 Notes Indenture includes covenants that restrict Group and its restricted subsidiaries' (including the Co-Issuer's) ability to, among other things:

● incur indebtedness;

● issue certain preferred stock or similar equity securities;

● pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock;

● make certain investments and other restricted payments, such as prepayment, redemption or repurchase of certain subordinated indebtedness;

● create liens;

● consolidate, merge, sell or otherwise dispose of all or substantially all of the properties and assets of Group and its restricted subsidiaries taken as a whole;

● incur restrictions on the ability of a restricted subsidiary to pay dividends or make other payments; and

● enter into transactions with affiliates.

However, the covenants provide for certain exceptions to these restrictions, and neither the Company nor any subsidiary of the Company that is not Group or a subsidiary of Group is subject to the covenants under the 2032 Notes Indenture. Certain covenants will cease to apply to the 2032 Notes if, and for so long as, the 2032 Notes have investment grade ratings from any two of Moody's Investors Service, Inc., Fitch Ratings, Inc. and S&P Global Ratings and so long as no default or event of default under the 2032 Notes Indenture has occurred and is continuing. Upon suspension of the covenants, the 2032 Notes Guarantees and the related liens on the collateral, as applicable, will be released until such time as the covenants are no longer suspended.

The principal amount of the 2032 Notes would become immediately due and payable upon the occurrence of certain bankruptcy or insolvency events involving Group, the Co-Issuer or certain of Group's subsidiaries, and may be declared immediately due and payable by the trustee or the holders of at least 25.0% of the aggregate principal amount of the then-outstanding 2032 Notes upon the occurrence of certain events of default under the Indenture. Events of default include the following with respect to the Issuers and Group's significant subsidiaries: (i) failure to pay principal, premium or interest at required times; (ii) failure to comply with any other agreements in the Indenture; (iii) default on certain material indebtedness that is caused by a failure to make a payment within any applicable grace period when due at maturity or results in the acceleration of such indebtedness prior to its express maturity; (iv) failure to pay certain material judgments; (v) a Guarantee being held unenforceable or invalid or ceasing for any reason to be in full force and effect or a Guarantor denying or disaffirming its obligations under its Guarantee; (vi) certain events of bankruptcy or insolvency; and (vii) certain defaults with respect to the security documentation related to the 2032 Notes and the collateral securing the 2032 Notes and the Guarantees of the Subsidiary Guarantors.

*Issuance of $174.4 million of New IPv4 Notes*

On April 11, 2025 (the "New IPv4 Notes Closing Date"), Cogent IPv4 LLC (the "IPv4 Issuer"), a special-purpose, bankruptcy remote, indirect wholly owned subsidiary of the Company, issued $174.4 million aggregate principal amount of secured IPv4 address revenue notes, Series 2025-1 Class A-2 (collectively, the "New IPv4 Notes"), with an anticipated repayment date ("ARD") in April 2030, in an offering exempt from registration under the Securities Act. The New IPv4 Notes bear interest at a rate of 6.646%, which is paid monthly.

The net proceeds of the New IPv4 Notes, after offering expenses, were $170.5 million. At the New IPv4 Notes Closing Date, $72.6 million of the net proceeds were restricted, and $97.9 million of the net proceeds were unrestricted. The restricted cash proceeds become available based upon improvements in the monthly leverage ratio and debt service coverage ratio (both as defined in the IPv4 Notes Indenture (as defined below). During the three months ended March 31, 2026 and year ended December 31, 2025 the restriction on $13.5 million and $26.9 million, respectively, of restricted cash was released primarily due to an improvement in the Company's monthly leverage and debt service coverage ratios under the IPv4 base Indenture. Under the Terms of the IPv4 Notes Indenture, the Company has until October 2026 to satisfy the performance metrics and unlock the remaining restricted funds. If there are any remaining restricted funds at that time, they will be used to pay principal on the New IPv4 Notes.

The New IPv4 Notes were issued pursuant to the IPv4 Base Indenture, dated as of May 2, 2024, as supplemented by the Series 2025-1 Supplement thereto, dated as of the New IPv4 Notes Closing Date (the "Series 2025-1 Supplement"), by and between the IPv4 Issuer and the IPv4 Trustee (as defined below). The IPv4 Base Indenture allows the IPv4 Issuer to issue additional series of notes subject to certain conditions set forth therein, and the IPv4 Base Indenture, together with the Series 2024-1 Supplement thereto (as defined below) and the Series 2025-1 Supplement, and any other series supplements to the IPv4 Base Indenture, is referred to as the "IPv4 Notes Indenture." Under the IPv4 Notes Indenture, interest is paid on a monthly basis. From and after the monthly payment date in April of 2030, principal payments will also be required to be made on the New IPv4 Notes on a monthly basis. No principal payments will be due on the New IPv4 Notes prior to the monthly payment date in April of 2030, unless certain rapid amortization, mandatory prepayment or acceleration events occur. The legal final maturity date of the New IPv4 Notes is in April of 2055. If the IPv4 Issuer has not repaid or refinanced any New IPv4 Notes prior to the monthly payment date in April of 2030, additional interest will accrue thereon in an amount equal to the greater of (i) 5.0% per annum and (ii) the excess amount, if any, by which the sum of the following exceeds the interest rate for such New IPv4 Notes: (A) the yield to maturity (adjusted to a "mortgage-equivalent basis" pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the monthly payment date in April of 2030 of the United States Treasury Security having a remaining term closest to 10 years; plus (B) 5.0%; plus (C) the post ARD note spread of 3.00% applicable to such New IPv4 Notes.

[**Table of Contents**](#TOC)

In connection with the issuance of the New IPv4 Notes, the IPv4 Issuer obtained consents from noteholders representing more than 50% of the Voting Rights (as defined in the IPv4 Base Indenture) of the Existing IPv4 Notes to adopt amendments to the IPv4 Base Indenture to, among other things, permit the IPv4 Issuer to (i) issue additional Class A Notes (as defined in the IPv4 Base Indenture) (provided that the Class A Leverage Ratio (as defined in the IPv4 Base Indenture) is less than or equal to 7.25 to 1.00) (as opposed to 6.10 to 1.00 under the Base Indenture as previously in effect), (ii) dispose of IPv4 addresses owned by the IPv4 Issuer (provided that the pro forma Leverage Ratio (as defined in the IPv4 Base Indenture) is less than or equal to 7.25 to 1.00) (as opposed to the greater of (x) 7.10 to 1.00 and (y) the Leverage Ratio as of the date of the most recent issuance of Additional Notes (as defined in the IPv4 Base Indenture) (after giving effect to the issuance of such Additional Notes) under the IPv4 Base Indenture as previously in effect) and (iii) substitute new IPv4 addresses (including Non-Contributed IP Addresses (as defined in the IPv4 Base Indenture)) to be owned by the IPv4 Issuer for the Contributed IP Addresses then owned by the IPv4 Issuer (provided that the pro forma Leverage Ratio is not greater than 7.25 to 1.00) (as opposed to 6.10 to 1.00 under the IPv4 Base Indenture as previously in effect), in each case, among other applicable requirements (collectively, the "Amendments"). Accordingly, on the New IPv4 Notes Closing Date, prior to the issuance of the New IPv4 Notes, the IPv4 Issuer entered into a second amendment to the IPv4 Base Indenture (the "Second Amendment") with the IPv4 Trustee giving effect to the Amendments.

*Issuance of $206.0 million of Existing IPv4 Notes*

On May 2, 2024, the IPv4 Issuer issued $206.0 million aggregate principal amount of IPv4 Notes (the "Existing IPv4 Notes"), with an ARD in May 2029 in an offering exempt from registration under the Securities Act. The net proceeds from the offering, after debt offering costs, were $198.4 million. The Existing IPv4 Notes bear interest at a rate of 7.924% which is paid monthly.

The Existing IPv4 Notes were issued pursuant to an indenture, dated as of May 2, 2024 (the "IPv4 Base Indenture"), as supplemented by the Series 2024-1 Supplement thereto, dated as of May 2, 2024 (the "Series 2024-1 Supplement"), in each case entered into by and between the IPv4 Issuer and Wilmington Trust, National Association, as the trustee for the IPv4 Notes (the "IPv4 Trustee"). The IPv4 Base Indenture allows the IPv4 Issuer to issue additional series of notes subject to certain conditions set forth therein.

The Existing IPv4 Notes were issued as part of a securitization transaction, pursuant to which certain IPv4 addresses, customer IPv4 address leases, customer accounts receivable and other IPv4 address assets (collectively, "IPv4 Address Assets") were contributed to the IPv4 Issuer and are included as collateral for the Existing IPv4 Notes. While the Existing IPv4 Notes are outstanding, scheduled payments of interest are required to be made on a monthly basis. From and after the monthly payment date in May of 2029, principal payments will also be required to be made on the Existing IPv4 Notes on a monthly basis. No principal payments will be due on the Existing IPv4 Notes prior to the monthly payment date in May of 2029, unless certain rapid amortization, mandatory prepayment or acceleration events occur. The legal final maturity date of the Existing IPv4 Notes is in May of 2054. If the IPv4 Issuer has not repaid or refinanced the Existing IPv4 Notes prior to the monthly payment date in May of 2029, additional interest will accrue thereon in an amount equal to the greater of (i) 5.0% per annum and (ii) the excess amount, if any, by which the sum of the following exceeds the interest rate for such Existing IPv4 Note: (A) the yield to maturity (adjusted to a "mortgage-equivalent basis" pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the monthly payment date in May of 2029 of the United States Treasury Security having a remaining term closest to 10 years; plus (B) 5.0%; plus (C) the post ARD note spread of 3.400% applicable to such Existing IPv4 Notes.

*IPv4 Notes collateral, guaranty, covenants and restrictions*

The IPv4 Notes are obligations only of the IPv4 Issuer pursuant to the indenture (the "IPv4 Notes Indenture"), and are secured by a security interest in substantially all of the IPv4 Address Assets pursuant to the IPv4 Notes Indenture. The IPv4 Notes are guaranteed by Cogent IPv4 Holdco LLC, a special-purpose entity and an indirect wholly owned subsidiary of the Company, as the guarantor (in such capacity, the "IPv4 Guarantor"), pursuant to a guaranty, dated as of May 2, 2024 (the "Guaranty") by the IPv4 Guarantor in favor of the IPv4 Trustee pursuant to which the IPv4 Guarantor has granted a security interest in the equity interests of the IPv4 Issuer as collateral security for its obligations under the Guaranty. Except as described below, neither the Company nor any subsidiary of the Company, other than the IPv4 Issuer and the IPv4 Guarantor, will guarantee or in any way be liable for the obligations of the IPv4 Issuer under the IPv4 Notes Indenture or the IPv4 Notes.

Page **18** of **46**

[**Table of Contents**](#TOC)

The IPv4 Notes are subject to a series of covenants and restrictions customary for transactions of this type. These covenants and restrictions include (i) that the IPv4 Issuer maintains a liquidity reserve account to be used to make required payments in respect of the IPv4 Notes with such funds considered restricted cash, (ii) provisions relating to optional and mandatory prepayments, including specified make-whole payments in the case of certain optional prepayments of the IPv4 Notes prior to the monthly payment date in May of 2028, (iii) certain indemnification payments in the event, among other things, that the transfers of the assets pledged as collateral for the IPv4 Notes are in stated ways defective or ineffective and (iv) covenants relating to recordkeeping, access to information and similar matters. As provided in the IPv4 Base Indenture, the IPv4 Notes are also subject to rapid amortization in the event of a failure to maintain a stated debt service coverage ratio as defined in the IPv4 Notes Indenture. A rapid amortization may be cured if the debt service coverage ratio exceeds a certain threshold for a certain period of time, upon which cure, regular amortization, if any, will resume. In addition, if certain utilization thresholds are not met (i.e., the proportion of IP addresses which are leased to the total number of IP addresses owned by the IPv4 Issuer falls below certain thresholds), the IPv4 Issuer will be required to apply collections to the repayment of the IPv4 Notes and in certain circumstances, the noteholders will have the ability to direct a sale of the IP Address Assets, in whole or in part, pursuant to the terms set forth in the IPv4 Notes Indenture. The IPv4 Notes are also subject to certain customary events of default, including events relating to non-payment of required interest, principal or other amounts due on or with respect to the IPv4 Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective and certain judgments.

*IPv4 Notes Manager*

Cogent Communications, LLC (in such capacity, the "Manager") performs certain monthly services related to the IPv4 Address Assets and the $380.4 million of IPv4 Notes including billing customers, collecting amounts paid by customers, forwarding payments to the IPv4 Trustee related to the IPv4 Address Assets and other administrative services. Amounts received by the IPv4 Issuer in respect of collections on the IPv4 Address Assets are reconciled on a monthly basis, and the IPv4 Issuer pays the monthly interest on the IPv4 Notes and other expenses from the accumulated customer payments on the IPv4 Address Assets. Amounts received by the IPv4 Issuer as collections on IPv4 Address Assets before the monthly reconciliation is completed are held in a segregated account by the IPv4 Trustee as collateral for the IPv4 Notes. After the IPv4 Trustee pays the monthly interest and other IPv4 Address Assets related costs, including monthly fees paid to the Manager for its services, any residual cash is paid to the Company and becomes unrestricted.

*Issuance of $300.0 million of 2027 Mirror Notes*

On June 11, 2024, the Issuers completed an offering of $300.0 million aggregate principal amount of its 2027 Mirror Notes for issuance in a private placement not registered under the Securities Act. The 2027 Mirror Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers in an unregistered offering pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in transactions outside the United States in compliance with Regulation S under the Securities Act. The 2027 Mirror Notes have the same maturity date and call protection, bear interest at the same rate and otherwise have substantially the same terms as the 2027 Notes; however, the 2027 Mirror Notes are not fungible (from a trading or tax perspective) with the 2027 Notes and are a separate series of notes from the 2027 Notes.

The 2027 Mirror Notes were issued at a price equal to 98.50% of their face value. The net proceeds from the offering were approximately $291.9 million after deducting the discount and offering expenses. Group used $114.6 million of the net proceeds from the offering to exercise a contractual option to prepay in full the IRU lease noted above, at a discount. Interest on the 2027 Mirror Notes accrues at 7.00% and is paid semi - annually in arrears on June 15 and December 15 of each year. Holdings provided a guarantee of the 2027 Mirror Notes, but Holdings is not subject to the covenants under the indenture.

The 2027 Mirror Notes were issued pursuant to, and are governed by, an indenture, dated June 11, 2024 (the "2027 Mirror Notes Indenture"), among the Issuers, the Company, the other guarantors named therein and Wilmington Trust, National Association, as trustee (the "2027 Notes Trustee"). The 2027 Mirror Notes are jointly and severally guaranteed (the "Guarantees") on a senior unsecured basis by each of Group's existing and future material domestic subsidiaries (other than the Co-Issuer), subject to certain exceptions (collectively, the "Subsidiary Guarantors"), and by the Company (together with the Subsidiary Guarantors, the "Guarantors"). However, the Company is not subject to the covenants under the 2027 Mirror Notes Indenture. Under certain circumstances, the Guarantors may be released from these Guarantees without the consent of the holders of the 2027 Mirror Notes.

Page **19** of **46**

[**Table of Contents**](#TOC)

The 2027 Mirror Notes and the Guarantees are the Issuers' and the Guarantors' senior unsecured obligations. The 2027 Mirror Notes and the Guarantees are effectively subordinated to all of the Issuers' and the Guarantors' existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and are structurally subordinated to all indebtedness and other liabilities of subsidiaries that are not Subsidiary Guarantors. Without giving effect to collateral arrangements, the 2027 Mirror Notes and the Guarantees rank pari passu in right of payment with all of the Issuers' and the Guarantors' existing and future senior indebtedness, including the Issuers' 2026 Notes and the 2027 Notes. The 2027 Mirror Notes and the Guarantees rank contractually senior in right of payment to all of the Issuers' and the Guarantors' subordinated indebtedness and are structurally subordinated to any existing and future indebtedness and other liabilities of the Issuers' non-guarantor subsidiaries.

After June 15, 2024, the Issuers may redeem the 2027 Mirror Notes, in whole or in part, at a redemption price ranging from 103.5% of the aggregate principal amount of the 2027 Mirror Notes redeemed to par (depending on the year), in each case, as set forth in the 2027 Mirror Notes Indenture, plus accrued and unpaid interest, if any, to, but not including, the date of redemption.

If Group undergoes specific kinds of changes in control accompanied by certain ratings events, the Issuers will be required to offer to repurchase the 2027 Mirror Notes from holders at a price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. Additionally, if Group or any of its restricted subsidiaries sells assets and does not apply the proceeds from such sale in a certain manner or certain other events have not occurred, under certain circumstances, the Issuers will be required to use the net proceeds to make an offer to purchase the 2027 Mirror Notes at an offer price in cash equal to 100% of the principal amount of the 2027 Mirror Notes, plus accrued and unpaid interest, if any, to, but not including, the repurchase date. In connection with any offer to purchase all or any of the 2027 Mirror Notes (including a change of control offer, asset sale, offer or any tender offer), if holders of no less than 90% of the aggregate principal amount of the outstanding 2027 Mirror Notes validly tender their 2027 Mirror Notes, the Issuers or a third party are entitled to redeem any remaining 2027 Mirror Notes at the price paid to each holder.

The 2027 Mirror Notes Indenture includes covenants that restrict Group and its restricted subsidiaries' (including the Co-Issuer's) ability to, among other things: incur indebtedness; issue certain preferred stock or similar equity securities; pay dividends or make other distributions in respect of, or repurchase or redeem, capital stock; make certain investments and other restricted payments, such as prepayment, redemption or repurchase of certain indebtedness; create liens; consolidate, merge, sell or otherwise dispose of all or substantially all of the properties and assets of Group and its restricted subsidiaries taken as a whole; incur restrictions on the ability of a subsidiary to pay dividends or make other payments; or enter into transactions with affiliates. The covenants provide for certain exceptions to these restrictions, and the Company is not subject to the covenants under the 2027 Mirror Notes Indenture. Certain covenants will cease to apply to the 2027 Mirror Notes if, and for so long as, the 2027 Mirror Notes have investment grade ratings from any two of Moody's Investors Service, Inc., Fitch Ratings, Inc. and S&P Global Ratings and so long as no default or event of default under the 2027 Mirror Notes Indenture has occurred and is continuing. Upon suspension of the covenants, the Guarantees will be released until such time as the covenants are no longer suspended.

The principal amount of the 2027 Mirror Notes would become immediately due and payable upon the occurrence of certain bankruptcy or insolvency events involving Group, the Co-Issuer or certain of Group's subsidiaries, and may be declared immediately due and payable by the 2027 Notes Trustee or the holders of at least 25% of the aggregate principal amount of the then-outstanding 2027 Mirror Notes upon the occurrence of certain events of default under the 2027 Mirror Notes Indenture. Events of default include the following with respect to the Issuers and Group's significant subsidiaries: (i) failure to pay principal, premium or interest at required times; (ii) failure to comply with any other agreements in the 2027 Mirror Notes Indenture; (iii) default on certain material indebtedness that is caused by a failure to make a payment within any applicable grace period when due at maturity or results in the acceleration of such indebtedness prior to its express maturity; (iv) failure to pay certain material judgments; (v) a Guarantee being held unenforceable or invalid or ceasing for any reason to be in full force and effect or a Guarantor denying or disaffirming its obligations under its Guarantee; and (vi) certain events of bankruptcy or insolvency.

*Issuance of $450.0 million of 2027 Notes*

On June 22, 2022 (the "2027 Notes Closing Date"), Group completed its offering of $450.0 million aggregate principal amount of its 2027 Notes for issuance in a private placement not registered under the Securities Act of 1933, as amended (the "Securities Act"). The 2027 Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers in an unregistered offering pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in transactions outside the United States in compliance with Regulation S under the Securities Act. The 2027 Notes were issued pursuant to, and are governed by, an indenture (the "2027 Notes Indenture"), dated the 2027 Notes Closing Date by and among Group, Holdings, the other guarantors named therein and the trustee. The 2027 Notes are jointly and severally guaranteed on a senior unsecured basis by each of the Company's existing and future material domestic subsidiaries, subject to certain exceptions, and by the Company. Under certain circumstances, the Guarantors may be released from these Guarantees without the consent of the holders of the 2027 Notes.

The net proceeds from the 2027 Notes offering were $446.0 million after deducting the $2.7 million discount and $1.3 million of offering expenses. Interest on the 2027 Notes accrues at 7.00% and is paid semi-annually in arrears on June 15 and December 15 of each year. Holdings provided a guarantee of the 2027 Notes, but Holdings is not subject to the covenants under the indenture.

Unless earlier redeemed or repurchased, the 2027 Notes will mature on June 15, 2027. After June 15, 2024, Group may redeem the 2027 Notes, in whole or in part, at a redemption price ranging from 103.5% of the aggregate principal amount of the 2027 Notes redeemed to par (depending on the year), in each case, as set forth in the 2027 Notes Indenture, plus accrued and unpaid interest, if any.

*Issuance of $500.0 million of 2026 Notes*

On May 7, 2021 (the "2026 Notes Closing Date"), Group completed an offering of $500.0 million aggregate principal amount of its 2026 Notes for issuance in a private placement exempt from registration under the Securities Act. The 2026 Notes were offered and sold only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to certain non-U.S. persons in transactions outside the United States in compliance with Regulation S under the Securities Act. The 2026 Notes were issued pursuant to, and are governed by, an indenture (the "2026 Notes Indenture"), dated the 2026 Notes Closing Date by and among Group, Holdings, the other guarantors named therein, the trustee and the collateral agent. The 2026 Notes are guaranteed on a senior secured basis, jointly and severally, by Group's material domestic subsidiaries, subject to certain exceptions (the "Subsidiary Guarantors"). In addition, the 2026 Notes were guaranteed on a senior unsecured basis by Holdings (together with the Subsidiary Guarantors, the "Guarantors"). The net proceeds from the 2026 Notes offering were $496.9 million after deducting the $1.8 million discount and $1.3 million of offering expenses.

Unless earlier redeemed or repurchased, the 2026 Notes were scheduled to mature on May 1, 2026. The 2026 Notes were extinguished and redeemed with the issuance of the 2032 Notes in June 2025.

*Limitations under the Indentures*

The indentures governing the 2032 Notes, the 2027 Notes, and the 2027 Mirror Notes (collectively, the "Indentures"), among other things, limit the ability of Group and its restricted subsidiaries to incur indebtedness; issue certain preferred stock or similar equity securities; pay dividends or make other distributions; make certain investments and other restricted payments; create liens; consolidate, merge, sell or otherwise dispose of all or substantially all of its properties and assets; incur restrictions on the ability of a subsidiary to pay dividends or make other payments; and enter into certain transactions with its affiliates. There are certain exceptions to the limitations on the ability to incur indebtedness under the Indentures, including IRU agreements incurred in the normal course of business and any additional indebtedness if Group's consolidated leverage ratio, as defined in the Indentures, is less than 6.0 to 1.0 or Group's fixed charge coverage ratio, as defined in the Indentures, is 2.0 to 1.0 or greater. Group and its subsidiaries can also incur unlimited liens (which can be used, together with capacity under the debt covenant, to incur additional secured indebtedness) if Group's consolidated secured leverage ratio, as defined in the Indentures, is less than 4.0 to 1.0. Under the Indentures, Group and its restricted subsidiaries can pay dividends, make other distributions, make certain investments and make other restricted payments under certain circumstances, including, with respect to its restricted payments, if, after giving pro forma effect to such restricted payment, Group could still incur $1 of "Ratio Debt," as defined (i.e., either its consolidated leverage ratio is less than 6.0 to 1.0 or its fixed charge coverage ratio is 2.0 to 1.0 or greater).

*Unrestricted Payments*

As of March 31, 2026, a total of $354.0 million was unrestricted and permitted for restricted payments, including dividends and stock purchases.

*Interest Rate Swap Agreement*

As of December 31, 2025, the Company was party to the Swap Agreement that has the economic effect of modifying the fixed interest rate obligation associated with its 2026 Notes to a variable interest rate obligation based on the Secured Overnight Financing Rate ("SOFR") so that the interest payable on the 2026 Notes effectively became variable based on overnight SOFR. The Swap Agreement was an independent agreement from the Company's now extinguished 2026 Notes and remained outstanding until its maturity in February 2026. Under the Swap Agreement, the Company paid the counterparty a semi-annual payment based upon overnight SOFR plus a contractual interest rate spread, and the counterparty paid the Company a semi-annual fixed 3.50% interest payment. The settlement payments were made each November and May.

The Swap Agreement was recorded at its fair value at each reporting period, and the Company incurred gains and losses due to changes in market interest rates. The values that the Company reported for the Swap Agreement as of each reporting date were recognized as "interest expense including change in valuation – interest rate swap agreement" with the corresponding amounts included in assets or liabilities in the Company's condensed consolidated balance sheets.

As of December 31, 2025, the fair value of the Swap Agreement was a net liability of $4.1 million, which was presented with accrued and other current liabilities. As of December 31, 2025, the Company had made a $4.3 million deposit with the counterparty to the Swap Agreement. As of December 31, 2025, $4.1 million of the deposit was restricted and $0.2 million was unrestricted. The Swap Agreement was settled on February 5, 2026 with a payment of $4.1 million and the total $4.3 million cash deposit was released and the account was closed.

**4. Commitments and contingencies**:

*Current and potential litigation*

In accordance with the accounting guidance for contingencies, the Company accrues its estimate of a contingent liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Where it is probable that a liability has been incurred and there is a range of expected loss for which no amount in the range is more likely than any other amount, the Company accrues at the low end of the range. The Company reviews its accruals at least quarterly and adjusts them to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular matter. The Company has taken certain positions related to its obligations for leased circuits for which it is reasonably possible to result in a loss of up to $4.6 million in excess of the amount accrued at March 31, 2026.

In the ordinary course of business, the Company is involved in other legal activities and claims. Because such matters are subject to many uncertainties and the outcomes are not predictable with assurance, the liability related to these legal actions and claims cannot be determined with certainty. Management does not believe that such claims and actions will have a material impact on the Company's financial condition or results of operations. Judgment is required in estimating the ultimate outcome of any dispute resolution process, as well as any other amounts that may be incurred to conclude the negotiations or settle any litigation. Actual results may differ from these estimates under different assumptions or conditions, and such differences could be material.

**6. Common stock buyback program:**

The Company's Board of Directors has approved purchases of shares of the Company's common stock under a buyback program (the "Buyback Program") through December 31, 2026. As of March 31, 2026, there was $105.8 million remaining for purchases under the Buyback Program. There were no purchases of common stock in the three months ended March 31, 2026 or in the three months ended March 31, 2025.

**7. Dividends on common stock:**

On May 1, 2026, the Company's Board of Directors approved the payment of a quarterly dividend of $0.02 per share of common stock. This estimated $1.0 million dividend payment is expected to be made on June 2, 2026.

The payment of any future dividends and any other returns of capital, including stock buybacks, will be at the discretion of the Company's Board of Directors and may be reduced, eliminated or increased and will be dependent upon the Company's financial position, results of operations, available cash, cash flow, capital requirements, limitations under the Company's debt indentures and other factors deemed relevant by the Company's Board of Directors. The Company is a Delaware corporation, and under the General Corporation Law of the State of Delaware, distributions may be restricted including a restriction that distributions, including stock purchases and dividends, do not result in an impairment of a corporation's capital, as defined under Delaware law. The Indentures limit the Company's ability to return cash to its stockholders.

**8. Related party transactions:**

*Office leases*

The Audit Committee of the Company's Board of Directors (the "Audit Committee") reviews and approves all transactions with related parties.

The Company's headquarters is located in an office building owned by Sodium LLC whose owner is the Company's Chief Executive Officer and Chairman, David Schaeffer. The fixed annual rent for the headquarters building is $1.0 million per year plus an allocation of taxes and utilities. The lease began in May 2015, and the lease term was for five years. In February 2020, the lease term was extended to May 2025 and in March 2025 the lease was extended to May 2030. The lease is cancellable at no cost by the Company upon 60 days' notice.

On January 6, 2023, the Company entered into two lease agreements (the "New Leases"), one with Thorium LLC ("Thorium") and one with Germanium LLC ("Germanium"), entities owned by the Company's Chief Executive Officer and Chairman, David Schaeffer. The first of the New Leases is with Thorium for 54,803 square feet of office space, which serves as office space for the Company replacing a portion of its office space in the Northern Virginia area ("Office Lease"). The second of the New Leases is with Germanium LLC for 1,587 square feet of technical space which serves as network operations space for the Company ("Network Operations Lease"). The term for each of the New Leases is five years beginning on April 1, 2023. Both of the New Leases are cancellable by the Company without penalty upon 60 days written notice. The Company took occupancy of the office space and network operations space in April 2023. The amount of fixed annual rent during the term of the Office Lease is $1.2 million, and the Company is responsible for paying its proportionate share of the building's operating expenses that exceed a 2023 base year. The amount of fixed annual rent for the Network Operations Lease is $34,914, and the Company is also responsible for paying its metered utility costs and a proportionate share of the building's other operating expenses that exceed a 2023 base year.

On July 25, 2023, the Company entered into a Second Amendment to the lease agreement with Germanium (the "Amendment"), which amended the Network Operations Lease to lease an additional 7,369 square feet on the first floor of the building, beginning on August 1, 2023, in connection with the planned expansion of the technical space. This included 4,987 square feet for an auditorium suitable for training and 2,382 square feet for the data center in the building. The amended Network Operations Lease remains cancellable by the Company without penalty upon 60 days written notice. The Amendment provides for $162,118 of additional fixed annual rent during the term of the Network Operations Lease, plus a proportionate share of real estate taxes and operating expenses and separately metered utilities expense.

The Company paid $0.8 million and $0.8 million in the three months ended March 31, 2026 and 2025, respectively, for rent and related costs (including taxes and utilities) for these leases.

**9. Geographic and segment information:**

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker ("CODM") in deciding how to allocate resources and in assessing the Company's performance. The Company's Chief Executive Officer and Chairman, David Schaeffer is the Company's CODM. The Company has one operating segment. The consolidated operating segment financial information regularly reviewed by the CODM, inclusive of assets, revenue, expenses, profit or loss, and noncash items are included in the Condensed Consolidated Statements of Comprehensive Income (Loss), Condensed Consolidated Balance Sheets, and Condensed Consolidated Statements of Cash Flows.

**ITEM 2.** **MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

You should read the following discussion and analysis together with our condensed consolidated financial statements and related notes included in this report. The discussion in this report contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. The cautionary statements made in this report should be read as applying to all related forward-looking statements wherever they appear in this report. Factors that could cause or contribute to these differences include those discussed in "Item 1A. Risk Factors," as well as those discussed elsewhere. You should read "Item 1A. Risk Factors" and "Special Note Regarding Forward-Looking Statements." Our actual results could differ materially from those discussed here. Factors that could cause or contribute to these differences include, but are not limited to:

Our acquisition of Sprint Communications, now called Cogent Fiber, LLC, including difficulties integrating our business with the Cogent Fiber Business, which may result in the combined company not operating as effectively and efficiently as expected; government policies worldwide; vaccination and in-office requirements, delays in the delivery of network equipment or optical fiber, loss of key right-of-way agreements, future economic instability in the global economy, including the risk of economic recession and bank failures and liquidity concerns at certain other banks, which could affect spending on Internet services; the impact of changing foreign exchange rates (in particular the Euro to US dollar and Canadian dollar to US dollar exchange rates) on the translation of our non-US dollar denominated revenues, expenses, assets and liabilities into US dollars; legal and operational difficulties in new markets; our ability to maintain our regulatory licenses that are required in the markets in which we operate; the imposition of a requirement that we contribute to the US Universal Service Fund on the basis of our Internet revenue; changes in government policy and/or regulation, including rules regarding data protection, cyber security and net neutrality; increasing competition leading to lower prices for our services; our ability to attract new customers and to increase and maintain the volume of traffic on our network; the ability to maintain our Internet peering and right-of-way arrangements on favorable terms; our ability to renew our long-term leases of optical fiber and right-of-way agreements that comprise our network; our reliance on a limited number of equipment vendors, and the potential for hardware or software problems associated with such equipment; our inability to obtain the equipment necessary for our expansion plans and customer requirements; tariffs imposed on equipment we purchase for our network or other similar government-imposed fees and charges; the dependence of our network on the quality and dependability of third-party fiber and right-of-way providers; our ability to retain certain customers that comprise a significant portion of our revenue base; the management of network failures and/or disruptions; our ability to make payments on our indebtedness as they become due and outcomes in litigation, as well as other risks discussed from time to time in our filings with the Securities and Exchange Commission, including, without limitation, our Annual Report on Form 10-K for the year ended December 31, 2025 and our Quarterly Reports on Form 10-Q.

**Acquisition of Cogent Fiber Business**

On May 1, 2023 (the "Closing Date"), Cogent Infrastructure, Inc. (now Cogent Infrastructure, LLC), a Delaware corporation and our direct wholly owned subsidiary (the "Buyer", "Cogent Infrastructure", "we" or "us"), closed on its acquisition of the U.S. long-haul fiber network (including the non-U.S. extensions thereof) of Sprint Communications and its subsidiaries (the "Cogent Fiber Business") in accordance with the terms and conditions of the Membership Interest Purchase Agreement (the "Purchase Agreement"), dated September 6, 2022, by and among us, Sprint Communications LLC, a Kansas limited liability company ("Sprint Communications") and an indirect wholly owned subsidiary of T-Mobile US, Inc., a Delaware corporation ("T-Mobile"), and Sprint LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of T-Mobile (the "Seller"). On the Closing Date, we purchased from the Seller all of the issued and outstanding membership interests (the "Purchased Interests") of Wireline Network Holdings LLC, a Delaware limited liability company that, following an internal restructuring and divisive merger, held Sprint Communications' assets and liabilities relating to the Cogent Fiber Business (such transactions contemplated by the Purchase Agreement, collectively, the "Transaction").

**Purchase Price**

On the Closing Date, we consummated the Transaction pursuant to the terms of the Purchase Agreement, providing a purchase price of $1 payable to the Seller for the Purchased Interests, subject to customary adjustments, including working capital (the "Working Capital Adjustment"), as set forth in the Purchase Agreement. As consideration for the Purchased Interests, the Working Capital Adjustment (primarily related to acquired cash and cash equivalents of an estimated $43.4 million at the Closing Date in order to fund the international operations of the Cogent Fiber Business) resulted in us making a payment to the Seller of $61.1 million on the Closing Date. In April 2024, an additional Working Capital Adjustment of $5.0 million was paid to the Seller.

[**Table of Contents**](#TOC)

*Short-term Lease Payment*

The Purchase Agreement provides for a payment of $28.1 million ($19.8 million net of discount) from the Seller to us related to acquired short-term operating lease obligations (the "Short - term Lease Payment"). The Short - term Lease Payment will be paid from the Seller to us in four equal payments in months 55 to 58 after the Closing Date. The final determination of the Short-term Lease Payment was completed in April 2024. The Short-term Lease Payment was recorded at its present value resulting in a discount of $8.4 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment.

*IP Transit Services Agreement*

On the Closing Date, we entered into an agreement for IP transit services ("IP Transit Services Agreement"), pursuant to which TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments of $29.2 million per month during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments of $8.3 million per month over the subsequent 42 months. Under the IP Transit Services Agreement, TMUSA paid us $25.0 million both during the three months ended March 31, 2026 and 2025.

We accounted for the Transaction as a business combination under ASC Topic 805 *Business Combinations* ("ASC 805"). We evaluated what elements are part of the business combination and the consideration exchanged to complete the acquisition. Under ASC 805, we concluded that the $700.0 million of payments to be made represent consideration received from T-Mobile to complete the acquisition of a distressed business. We also evaluated whether the IP Transit Services Agreement was in the scope of ASU No. 2014-09 *Revenue from Contracts with Customers* ("ASC 606"). We concluded that T-Mobile did not represent a "customer" as defined by ASC 606, the stated contract price did not represent consideration for services to be delivered, and the transaction did not satisfy the definition of revenue, which excluded this arrangement from the scope of ASC 606. As a result, and considering statements made by T-Mobile, the IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount of $79.6 million. The interest rate used in determining the present value was derived considering rates on similar issued debt instruments with comparable durations, among other market factors. The determination of the discount rate requires some judgment.

**Competitive Advantages**

We believe we address many of the data communications needs of a diverse group of businesses, communications service providers and other bandwidth-intensive organizations by offering high-quality, high-speed Internet access, optical transport and optical wave services, and private network services at attractive prices. We believe that our organization has the following competitive advantages:

*Low Cost of Operation.* We believe that the wireline telecom industry is undergoing, and will continue to face, significant price deflation for its applications and services. This price deflation is a result of a variety of factors including increased competition, enhanced substitutability of certain products and services and the continued impact of Moore's Law, which has driven down the cost of technology, particularly for fiber optic Wavelength Division Multiplexing equipment and optically interfaced routers. Faced with the backdrop of continued price deflation in our industry, we have made a series of discrete choices around our network design, operating strategy and product offerings that are consistent with our objective of becoming the low-cost operator in our industry. Since our initiation of operations, this strategy has resulted in a rapid decline in our cost to transmit bits, which has increased our margins and decreased our capital intensity, excluding capital expenditures for the repurposing of acquired Sprint assets, as measured by our capital expenditures per total revenues. Important components of our low-cost operating strategy include:

● *One IP Network Protocol*. Upon our founding, we selected to operate our network that provides Internet - based services (our "IP Network") solely using Ethernet protocol. We made this selection in order to take advantage of the significantly greater installed base and lower cost of Ethernet network equipment versus other protocols, the substantially lower costs associated with operating and maintaining one network protocol and the continued benefits of the rapid price performance ratio improvements of Ethernet-related equipment. Our single network protocol allows us to avoid many of the costs that our competitors who operate circuit-switched, time-division multiplexing ("TDM") and hybrid fiber coaxial networks incur related to provisioning, monitoring and maintaining multiple transport protocols. Selecting one operating protocol has positively impacted our operating overhead and the simplicity of our organization. We believe the

Page **27** of **46**

[**Table of Contents**](#TOC)

vast majority of our competitors currently operate their networks with multiple protocols, and we believe that attempts to upgrade their networks to one protocol would be operationally challenging and costly.

● *Our IP Network*. We have acquired a large portfolio of dark fiber leases from over 380 dark fiber vendors from around the world sourced from the excess inventory of existing networks. The nature of this portfolio and the individual leases provide us long-term access to dark fiber at attractive rates and, in many cases, the opportunity to extend these leases for multiple terms. On average, a modest number of our dark fiber leases come up for renewal each year. In addition, with our acquisition of the Cogent Fiber Business, we now own a nationwide domestic fiber network (the "Sprint Network"). Acquiring the Sprint Network allows us to capitalize on the benefits of owning network without significant upfront capital investment. The Sprint Network is mostly complementary to our existing leased dark fiber network, offers unique geographic routes and will allow us to reduce our reliance on leased dark fiber. This strategic combination of owned and leased dark fiber will help to ensure a robust and reliable network and enables us to connect via dark fiber to virtually any geographic route or facility we require on a long-term, cost-effective basis.

● *Optical Wave Network.* Acquiring the Sprint Network has also allowed us to construct a wavelength network (our "Optical Wave Network") predominantly using the fiber that is owned by Cogent Fiber and leased to our operating subsidiary, Cogent Communications, LLC under a long-term IRU. This enables us to expand our product offerings to include optical wavelength and optical transport services. We are selling these services to our existing customers, customers acquired with the Cogent Fiber Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. As of March 31, 2026, we offered this service in 1,107 wave-enabled locations in the United States, Mexico and Canada. We believe our wavelength service has the advantages of unique routes, ubiquitous service locations, faster provisioning times and lower prices.

● *Narrow and Focused Product Set.* Since our founding, we have strategically focused on delivering a very narrow product set to our customers. The vast majority of our revenue is driven by or related to our high-capacity, bi-directional, symmetric Internet access services which can be accessed on-net in multi-tenant office buildings ("MTOBs") and carrier neutral data centers ("CNDCs") or off-net through other carriers' "last mile" connections to customer facilities. The addition of optical wave and optical transport services, our direct, virtual private network ("VPN") connection to cloud providers services and our decision to continue to support MPLS based VPN services for our acquired customers are consistent with this strategy. Consistent with this strategy, we have pared, and continue to pare, non-core services acquired with the Cogent Fiber Business. There are significant cost advantages because of this narrow product set. We believe that the relative size of our salesforce training, support and overhead is lower than comparable telecom providers that tend to offer a broader, one-stop shop product set to their client base.

● *Scalable Network Equipment and Hub Configurations*. We continue the process of optimizing our IP Network and Optical Wave Network for historical IP-based Internet services and optical wave (optical transport services), respectively. This process has not altered our primary reliance on two sets of equipment for operation, nor has the addition of optical waves (optical transport services) to our product set altered this equipment configuration. In order to further scale our operating leverage, we have systematically reused older equipment in less dense portions of our networks. Due to interoperability between the generations of products, we are able to transfer older equipment from our core, high-traffic areas to less congested portions in each network. The result of this dynamic grooming process is that we are able to utilize our equipment for materially longer periods than our competitors, thereby reducing our capital investment in our networks. We design and build all of our network hubs, points of presence, and data centers to the same standards and configurations. This replication strategy provides us scale benefits in equipment purchases, training, and maintenance.

[**Table of Contents**](#TOC)

● *Greater Control and Superior Delivery*. Our on-net service, whether provisioned on our IP Network or our Optical Wave Network, does not rely on circuits that must be provisioned by a third-party carrier. In our on-net MTOBs, we provide our customers their entire network connection, including the "last mile" and the in-building fiber optic connections to our customer's suite. In our CNDCs, we are collocated with our customers. As a result, only a cross-connection within the data center is required to provide our services to our customers, including our newer optical wave and optical transport offerings. The structure of our on-net service provides us with more control over our service, quality and pricing. It also allows us to provision services more quickly and efficiently than provisioning services on a third-party carrier network. The vast majority of our on-net Internet and VPN services can be installed in less than two weeks, which is materially faster than the installation times for some of our incumbent competitors. We are able to install our optical wave services, on average, in thirty business days or less, which we believe provides a competitive advantage.

● *High-Quality, Reliable Service.* We are able to offer high-quality Internet service due to our network design and composition. We believe that we deliver a high level of technical performance because our IP Network is optimized for packet routed traffic. Its design increases the speed and throughput of our IP Network and reduces the number of data packets dropped during transmission compared to traditional circuit-switched networks. We believe that our IP Network is more reliable and carries traffic at lower cost than networks providing similar services that were originally built as overlays to traditional circuit-switched, or TDM networks. With respect to our optical wave services, we believe that our Optical Wave Network offers advantages over other optical networks through its location along railroad rights of way and burial deeper than industry norms. We believe these two factors result in fewer cable cuts, and, as result, fewer service interruptions.

● *Large Addressable Market.* We have systematically evaluated and chosen our network extensions to buildings, data centers and markets based upon a rigorous set of criteria to evaluate the economic opportunity of network locations. Additional factors relevant to our pursuit of new buildings include the willingness of building owners to grant us access rights, the availability of optical fiber networks to serve those buildings, the costs to connect buildings to our network and equipment availability.

Our IP Network is connected to a total of 3,605 buildings that are located in 306 metropolitan markets globally. These buildings include:

● 1,875 large MTOBs (totaling over 1.0 billion square feet of office space);

● 1,744 CNDCs located in 1,545 buildings;

● 99 of our own AC powered Cogent data centers; and

● 86 of our smaller DC powered Cogent edge data centers.

Our MTOBs are located in major North American cities where we offer our services to a diverse set of high-quality corporate customers within close physical proximity of each other. Our CNDCs are located in North America, Europe, Asia, South America, Oceania and Africa where our net-centric customers directly interconnect with our network.

Our Optical Wave Network is connected to 1,107 wave enabled locations located in 153 metropolitan markets in the United States, Canada and Mexico. All of our wavelength services are on-net as they originate and terminate on our Optical Wave Network. Our Cogent data centers, including our Cogent Edge data centers, are directly connected to our network and operate across the United States and in Europe, and comprise 2.1 million square feet of floor space, and 211 MW of power.

Page **29** of **46**

[**Table of Contents**](#TOC)

We believe that these network points of presence strategically position our networks to attract high levels of Internet traffic and maximize our revenue opportunities and profitability.

*Balanced, High-Traffic IP Network.* Since its inception, our IP Network has grown significantly in terms of its geographic reach, customer connections, and traffic.

We currently serve:

● 7,630 access networks, as well as numerous large and small content providers;

● 65,098 net-centric customer connections,

● 41,903 corporate customer connections, and

● 9,808 enterprise customer connections.

Because of the number of customers who distribute (content providers) and receive (access networks) content on our IP Network, we believe that the majority of all the traffic remains "on-net" by both originating and terminating on our IP Network. This control of traffic is an important differentiator as it increases our service reliability and speed of traffic delivery. The increasing share of traffic delivered from content providers to access networks also enhances our margins as we are compensated by both the originating customer and the terminating customer. The breadth of our IP Network, extensive size of our customer base, and the volume of our traffic enables us to be one of a handful of Tier 1 networks that are interconnected with other Tier 1 networks on a settlement-free basis. This Tier 1 network peering status broadens our geographic delivery capability and materially reduces our network costs.

*Proven and Experienced Management Team*. Our senior management team is composed of seasoned executives with extensive expertise in the telecommunications industry as well as knowledge of the markets in which we operate. The members of our senior management team have an average of over 20 years of experience in the telecommunications industry and many have been working together at the Company for several years. Several members of the senior management team have been working together at the Company since 2000. Our senior management team has designed and built our IP Network and, later, our Optical Wave Network, led the integration of network assets we acquired through 14 significant acquisitions and managed the expansion and growth of our business. A number of the members of senior management who joined us as part of our acquisition of the Cogent Fiber Business have similar experience and tenure in both the telecommunications industry and at the Cogent Fiber Business. We believe that our management team has and will continue to successfully manage the integration of the Cogent Fiber Business into our current operations.

**Our Strategy**

We intend to remain a leading provider of high-quality, high-speed Internet access and private network services and to continue to improve our profitability and cash flow. The principal elements of our strategy include:

*Grow our Corporate Customer Base.* Our on-net corporate customers are typically small to medium-sized businesses connected to our IP Network through MTOBs or connected to our IP Network or our Optical Wave Network through one of our on-net CNDCs. We generally sell two types of services to our corporate customers: dedicated internet access and private network services. We sell a small amount of optical wave services to our corporate customers. We typically sell dedicated internet access at the same price per connection as our competitors, but our customers benefit from our significantly faster speeds and rapid installation times. These customers are increasingly integrating off-site data centers and cloud services into their IT infrastructure in order to take advantage of the safety, security and redundancy that is offered by locating company processing power, storage and software at a data center. An important part of this new infrastructure is a high-speed, dedicated internet connection from the corporate premises to the data center and the Internet and from one corporate premises to other corporate premises. We believe that the importance of data centers will increasingly lead tenants to reconfigure their communications infrastructure to include dedicated Internet access across their locations.

*Expand our Profitable Business with Enterprise Customers*. In conjunction with our acquisition of the Cogent Fiber Business, we acquired a number of larger enterprise customers. We have continued to provide our core services to enterprise customers and

Page **30** of **46**

[**Table of Contents**](#TOC)

elected to provide MPLS based VPN as well as VPLS services, a new service for these customers, but continue to terminate unprofitable services to these customers at the end of their current term. We have also elected to terminate certain unprofitable customer locations and, in limited circumstances, ceased providing services in certain countries where we could not do so economically. We have not previously focused our sales efforts on larger enterprise customers. Since the acquisition of the Cogent Fiber Business, we have formed dedicated sales personnel who are tasked with preserving existing business with and seeking new sales from enterprise customers.

*Increase our Share of the Net-Centric IP Market*. We are currently one of the leading providers of high-speed internet access to a variety of content providers and access networks across the world. We intend to further load our high-capacity IP Network as a result of the growing demand for high-speed Internet access generated by these types of bandwidth-intensive applications such as over-the-top media services, online gaming, video, Internet of Things, voice over IP, remote data storage, and other services. We expect that we will continue to grow our shares of these segments by offering our customers a series of attractive features including:

● *Geographic breadth –* We have one of the broadest CNDC footprints in the industry and currently offer network services in 57 countries – as net-centric customers seek a more international audience this footprint is a significant advantage;

● *High capacity and reliability –* We offer 100 Mbps to 100 Gbps ports in all of the CNDCs and 400 Gbps in selected locations on our IP Network, which differentiates the capacity choices we provide our net-centric customers;

● *Balanced customer base for IP services –* Our leading share of content providers and access networks increases the amount of traffic that originates and terminates on our IP Network thereby reducing latency and enhancing reliability; and

● *Large and dedicated salesforce –* Our team of net-centric sales professionals is one of the largest salesforces in this industry segment and enables us to better serve this customer segment while also identifying new sales opportunities and gaining new business and customers.

*Increase our Share of the Optical Wavelength Market.* We offer 10 Gbps, 100Gbps and 400 Gbps optical wavelength and optical transport services to our net-centric customers who require these high-bandwidth dedicated point-to-point services. We intend to become one of the leading providers of optical wavelength services in North America. Building upon the foundation provided by the assets of the Cogent Fiber Business, we have created, and continue to expand, our Optical Wave Network to provide optical wavelength services to hyper-scalers and other net-centric customers who require optical wave services. We believe that we offer our customers the following:

● *Diverse routes –* Our Optical Wave Network is located along rights of way that are largely unique. As such, we offer route diversity and geographic redundancy to our customers.

● *Ubiquitous Footprint –* We offer optical wavelength services in 1,107 locations in North America directly connected to our Optical Wave Network. This broad footprint allows us to meet customers in locations of their choosing and to provide fully on-net optical wave services to them in these locations.

● *Rapid Installation –* We are typically able to install our optical wave services in less than 30 business days, far below the current industry norm. We believe that over time the percentage of our optical wave services that are installed in 30 business days or less will continue to grow.

● *High Reliability –* We believe our Optical Wave Network suffers a lower frequency of interruptions and fiber cuts. The fiber in our Optical Wave Network is largely buried along railroad lines, making it less susceptible to inadvertent cuts, and is buried deeper than newer networks with stronger sheathing, mitigating some of the damage caused by inadvertent cuts. We believe a lower frequency of fiber cuts results in more reliable service for the customer.

● *Competitive Pricing –* We have historically been a price leader in the markets in which we provide service. We intend to continue that position in the market for optical wavelengths and offer highly competitive pricing to our customers.

*Pursue On-net Customer Growth to Corporate and Net - centric Customers.* Our high- capacity networks provide us with the ability to add a significant number of customers to either network, depending on the service offering, with minimal direct incremental

costs. We intend to increase usage of our networks and operational infrastructure by adding customers in our existing on-net buildings, as well as developing additional markets connecting more MTOBs and CNDCs to our IP Network and connecting more CNDCs to our Optical Wave Network. We emphasize our on-net services because they generate greater profit margins and we have more control over service levels, quality and pricing, and our on-net services are provisioned in considerably less time than our off-net services. Our networks connect directly to our on-net customers' premises and we pay no local access ("last mile") charges to other carriers to provide our on-net services.

*Continue to Improve our Sales Efforts and Productivity.* A critical factor in our success has been our investment and focus on our sales and marketing efforts. We seek to maintain a consistent level of sales productivity as measured by the number of connections sold per salesperson per month, considering adjustments to the changing mix of products sold and installed. In order to gain market share in our targeted businesses, we expect to continue our sales efforts including introducing strategies and tools to optimize and improve our sales productivity. We also intend to leverage the skills and relationships of our sales force to sell our expanded service offerings, in particular, optical wavelength and optical transport services. We have developed several training programs that are directed toward increasing our sales representative tenure and increasing our sales representative productivity. In addition, when consistent with their job description and responsibilities, we require all of our employees to work in the office on a full-time basis, thereby providing additional opportunities for management coaching and oversight in order to increase productivity.

*Expand our Off-net Corporate and Enterprise Internet Access and VPN Business*. We have agreements with over 740 national and international carriers providing us last mile network access to over 6 million commercial buildings that are lit by fiber optic cable in the countries we serve and that are not currently served by our network. We believe these agreements broaden our addressable market for corporate dedicated Internet access and private network services and enhances our competitive position through the ability to provide enterprise-wide connectivity for corporate customers. In order to take advantage of this large set of commercial buildings, we have developed an automated process to enable our salesforce to identify opportunities in the off-net market for dedicated Internet access and private network services and to quickly offer pricing proposals to potential customers. We continue to negotiate reduced pricing under our numerous carrier agreements that enable us to reduce our cost of off-net services, which enhances our competitive position in the marketplace.

*Expand our Product Offerings to Include Wavelength and Optical Transport Services*. In connection with our acquisition of the Cogent Fiber Business, we expanded our offerings to include optical wavelength and optical transport services over our Optical Wave Network. We are selling these services to our existing customers, customers acquired with the Cogent Fiber Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. As of March 31, 2026, we offered wavelength services in 1,107 wave-enabled locations in the United States, Mexico and Canada. We believe our wavelength service has the advantages of unique routes, ubiquitous service locations, faster provisioning times and lower prices.

*Expand our Data Center Footprint*. In connection with our acquisition of the Cogent Fiber Business, we acquired multiple Sprint facilities that previously housed Sprint equipment. We evaluated the suitability of these facilities for conversion to commercial data center space and began repurposing suitable facilities. Repurposing these facilities included removing unused, obsolete equipment and racks, converting many locations from DC power to AC power, and upgrading or installing new HVAC systems, uninterruptable power supplies, backup generators and fire suppression systems as well as other structural changes. By March 31, 2026, we had converted the former Sprint facilities into 53 Cogent data centers and 86 Cogent edge data centers. In connection with this conversion process, we also decommissioned certain legacy Cogent data centers.

*Increase our Leasing of IPv4 Address Space*. We lease IPv4 address space to our customers, both on a standalone basis and as a complement to a customer's Internet access services with us. Our IPv4 Issuer is our primary lessor of IPv4 address space with the remainder leased by our other operating subsidiaries. We also provide a small number of free IPv4 addresses to our dedicated Internet access customers. We currently own approximately 38 million IPv4 addresses. As of March 31, 2026, we were leasing 15.2 million of our IPv4 addresses to our customers on contracts with service terms ranging from one month to five years. We intend to continue to lease IPv4 addresses to our customers as well as explore alternatives for monetizing our IPv4 address inventory.

*Monetize Acquired Data Center Facilities*. We are actively marketing the sale or lease of 24 data center facilities acquired in the Transaction.

**Results of Operations**

*Three Months Ended March 31, 2026 Compared to the Three Months Ended March 31, 2025*

Our management reviews and analyzes several key financial measures in order to manage our business and assess the quality and variability of our service revenue, operating results and cash flows. The following summary tables present a comparison of our results of operations with respect to certain key financial measures. The comparisons illustrated in the tables are discussed in greater detail below.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes non-cash equity-based compensation expenses of $319 and $490 in the three months ended March 31, 2026 and 2025, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Includes non-cash equity-based compensation expenses of $7,244 and $7,523 in the three months ended March 31, 2026 and 2025, respectively.

*Service Revenue*. We continually work to grow our total service revenue by increasing the number of potential customers that we can reach on our IP Network and our Optical Wave Network. We do this by investing capital to expand the geographic footprint of our network, increasing the number of buildings connected to our network, including CNDCs and MTOBs, and increasing our penetration rate into our existing buildings. These efforts broaden the global reach of our network and increase the size of our potential addressable market. We also seek to grow our service revenue by investing in our sales and marketing team. We typically sell corporate connections at similar pricing to our competitors, but our customers benefit from our significantly faster speeds, greater aggregate throughput, enhanced service level agreements and rapid installation times. In the net-centric market, we offer comparable services in terms of capacity but typically at significantly lower prices.

Our service revenue decreased by 3.2% from the three months ended March 31, 2025 to the three months ended March 31, 2026. Exchange rates positively impacted our service revenue from the three months ended March 31, 2025 to the three months ended March 31, 2026 by $3.4 million. Our total service revenue decreased from the cancellation of low margin and non-core customers we acquired with the Cogent Fiber Business partially offset by the growth in customers from expanding our network, increasing our wavelength service revenue, adding additional buildings to our network, increasing our penetration into the buildings connected to our network and gaining market share by offering our services at lower prices than our competitors.

Revenue recognition standards include guidance relating to any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer and may include, but is not limited to, gross receipts taxes, Universal Service Fund fees and certain state regulatory fees. We record these taxes billed to our customers on a gross basis (as service revenue and network operations expense) in our condensed consolidated statements of comprehensive income. The impact of these taxes including the Universal Service Fund resulted in a decrease to our revenues of $0.7 million from the three months ended March 31, 2025 to the three months ended March 31, 2026.

*Revenue and customer connections by customer type*. Our corporate customers generally purchase their services on a price per connection basis. Our net-centric customers generally purchase their IP services on a price per megabit-metered basis and purchase their optical wavelength services on a per connection basis priced by a combination of distance, connection size and contract term. We began to serve enterprise customers in connection with our acquisition of the Cogent Fiber Business. We define "enterprise" customers as large corporations (typically, Fortune 500 companies with greater than $5 billion in annual revenue) running Wide Area Networks ("WAN") with several dozen to several hundred sites. Our enterprise customers generally purchase our services on a price per location basis.

We believe that we are in a unique position to monetize the Cogent Fiber Business and its network, and we expect to achieve significant cost reduction synergies and revenue synergies from the Transaction. On the Closing Date, with the Cogent Fiber Business we acquired:

● 17,823 corporate customer connections,

● 5,711 net-centric customer connections, and,

● 23,209 enterprise customer connections.

We classified the $39.5 million of May 2023 Cogent Fiber Business monthly revenue as:

● $20.1 million of monthly recurring revenue as enterprise revenue,

● $12.9 million of monthly recurring revenue as corporate revenue, and,

Page **34** of **46**

[**Table of Contents**](#TOC)

● $6.5 million of monthly recurring revenue as net-centric revenue.

Revenues from our corporate, net-centric and enterprise customers represented 42.3%, 44.2% and 13.5% of total service revenue, respectively, for the three months ended March 31, 2026 and represented 44.8%, 37.5% and 17.7% of total service revenue, respectively, for the three months ended March 31, 2025.

Our revenue from our corporate customers decreased primarily due to cancellations of low margin and non-core corporate customers acquired with the Cogent Fiber Business. Our corporate customers take advantage of our superior speeds, greater aggregate throughput, service levels and installation times versus our competitors. During the three months ended March 31, 2026, we continued to see declining vacancy rates compared to their peak during the COVID-19 pandemic and rising office occupancy rates in certain markets in which we operate continuing a trend that began following the end of the COVID-19 pandemic. Other markets, particularly those in California, Washington D.C. and the Pacific Northwest, continue to see markedly higher vacancy rates. These higher vacancy rates may represent a long-term change in office attendance and occupancy rates in these markets. Despite this overall environment, we are seeing some positive trends in our corporate business. As the option to fully or partially work from home becomes permanently established at many companies, our corporate customers are integrating some of the new applications that became part of the remote work environment, which benefits our corporate business as these customers upgrade their Internet access infrastructure to higher capacity connections. Further, if and when companies eventually return to the buildings in which we operate, we believe it will present an opportunity for increased sales. However, the exact timing and path of these positive trends remains uncertain.

Our revenue from our net-centric customers increased, primarily due to growth in network traffic from our legacy net-centric customers partly offset by a reduction in revenue from net-centric customers acquired with the Cogent Fiber Business. Our net-centric customers purchase our IP services on a price per megabit basis and purchase their optical wavelength services on a per connection basis priced by a combination of distance, connection size and contract term. The net-centric market exhibits significant pricing pressure due to the continued introduction of new technology, which lowers the marginal cost of transmission and routing, and the commodity nature of the service where price is typically the only differentiating factor for these customers. Our average price per megabit of our installed base of customers decreased by 36.1% from the three months ended March 31, 2025 to the three months ended March 31, 2026. The impact of foreign exchange rates has a more significant impact on our net-centric revenues.

Our revenue from our enterprise customers decreased primarily due to a reduction in revenue from low-margin and non-core enterprise customers acquired with the Cogent Fiber Business.

Revenue and customer connections by network connection type. On the Closing Date, we classified the total $39.5 million of monthly Cogent Fiber Business revenue as:

● $2.5 million of on-net revenue,

● $32.3 million of off-net revenue, and,

● $4.7 million of non-core revenue.

Additionally, on the Closing Date, we classified the total 46,743 Cogent Fiber Business customer connections as:

● 1,560 on-net customer connections,

● 24,667 off-net customer connections, and,

● 20,516 non-core customer connections.

Revenues from our on-net, off-net, wavelength and non-core customers represented 56.7%, 37.2%, 5.7% and 0.4% of total service revenue, respectively, for the three months ended March 31, 2026 and represented 52.5%, 43.4%, 2.9% and 1.2% of total service revenue, respectively, for the three months ended March 31, 2025.

Page **35** of **46**

[**Table of Contents**](#TOC)

Our on-net revenues increased from the three months ended March 31, 2025 to the three months ended March 31, 2026, primarily from an increase in revenues from our legacy Cogent customers. Of the $39.5 million of monthly revenue we acquired with the Cogent Fiber acquisition, only 6.3% was on-net revenue.

Our off-net revenues decreased from the three months ended March 31, 2025 to the three months ended March 31, 2026 primarily from cancellations of low-margin off-net customers and off-net customers in unlicensed markets that we acquired with the Cogent Fiber Business. Of the $39.5 million of monthly revenue we acquired with the Cogent Fiber acquisition, 81.7% was off-net revenue.

In connection with our acquisition of the Cogent Fiber Business, we expanded our offerings of optical wavelength and optical transport services over our fiber network. Wavelength revenue was $13.6 million for the three months ended March 31, 2026 and $7.1 million for the three months ended March 31, 2025.

Our non-core revenues decreased from the three months ended March 31, 2025 to the three months ended March 31, 2026 from the cancellation of non-core revenues acquired in the Cogent Fiber Business. Non-core services are services, which we acquired and continue to support but do not actively sell. Of the $39.5 million of monthly revenue we acquired with the Cogent Fiber acquisition, we classified 11.9% as non-core revenue.

*Network Operations Expenses.* Network operations expenses include the costs of personnel associated with service delivery, network management and customer support, network facilities costs, right-of-way fees, fiber and equipment maintenance fees, leased circuit costs, access and facilities fees paid to building owners and excise taxes billed to our customers and recorded on a gross basis. Non-cash equity-based compensation expense is included in network operations expenses consistent with the classification of the employee's salary and other compensation. The 6.0% decrease in network operations expense was primarily attributable to our efforts to reduce the network operations costs related to our acquisition of the Cogent Fiber Business. These costs primarily include leased circuit costs, including the reduction of the related "tail-circuit" costs for the reduction in off-net revenue and facilities costs.

*Selling, General, and Administrative ("SG&A") Expenses.* Our SG&A expenses, including non-cash equity-based compensation expense, decreased by 2.1% from the three months ended March 31, 2025 to the three months ended March 31, 2026. Our decrease in SG&A operations expense was primarily attributable to our efforts to reduce SG&A costs related to our acquisition of the Cogent Fiber Business. These costs primarily include compensation and related costs. Non-cash equity-based compensation expense is included in SG&A expenses consistent with the classification of the employee's salary and other compensation.

*Depreciation and Amortization Expenses.* Our depreciation and amortization expense decreased by 28.9%. The decrease was primarily due to assets acquired with the Cogent Fiber Business becoming fully depreciated, in particular acquired network equipment assets, more than offsetting the increase in our deployed fixed assets.

*Interest Income - IP Transit Services Agreement*. Under the IP Transit Services Agreement TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments over the subsequent 42 months. The IP Transit Services Agreement was recorded in connection with the Transaction at its discounted present value resulting in a discount of $79.6 million. The amortization of the discount resulted in interest income of $3.1 million for the three months ended March 31, 2026 and $4.7 million for the three months ended March 31, 2025.

*Interest Expense - Including Change in Valuation of Swap Agreement*. Our interest expense resulted from interest incurred on our:

● $500.0 million 2026 Notes issued in May 2021 until they were extinguished on June 17, 2025,

● $600.0 million 2032 Notes issued on June 17, 2025 in connection with the extinguishment of our 2026 Notes,

● $174.4 million of 6.646% New IPv4 Notes issued in April 2025 and our $206.0 million of 7.924% Existing IPv4 Notes issued in May 2024 (collectively the "IPv4 Notes"),

● $300.0 million of 7.00% Senior Unsecured Notes due 2027 issued in June 2024 (the "2027 Mirror Notes"),

● $450.0 million of 7.00% Senior Unsecured Notes due 2027 issued in June 2022 (the "2027 Notes"),

Page **36** of **46**

[**Table of Contents**](#TOC)

● Our interest rate swap agreement until it expired in February 2026; and

● Our finance lease obligations.

Our interest expense increased by 28.2% from the three months ended March 31, 2025 to the three months ended March 31, 2026. Our interest expense increased primarily due to the April 2025 issuance of our New IPv4 Notes, the June 2025 issuance of our 2032 Notes issued for $100.0 million of additional principal amount and at a higher interest rate compared to our extinguished 2026 Notes and our final $4.1 million payment on our interest rate swap agreement in February 2026.

*Income Tax Benefit.* Our income tax benefit was $11.4 million for the three months ended March 31, 2026 and $18.2 million for the three months ended March 31, 2025. The change in our income tax benefit is primarily related to projected operating results related to the Cogent Fiber Business acquisition and the reversal of deferred tax liabilities acquired with the Cogent Fiber Business.

*Buildings On-net.* As of March 31, 2026 and 2025, we had a total of 3,605 and 3,500 on-net buildings connected to our network, respectively. The increase in our on-net buildings was a result of our disciplined network expansion program. We anticipate adding a similar number of buildings to our network for the next several years.

**Liquidity and Capital Resources**

***Acquisition of Cogent Fiber Business***

*Acquisition of Cogent Fiber Business – Cash Flow*

The Cogent Fiber Business's cash flow was negative at the time of negotiations and during its recent history. Due to the dire financial condition of the Cogent Fiber Business, it was understood that a payment from T-Mobile to any potential buyer would be required to execute a transaction to give a buyer sufficient cash inflow to offset losses that would be expected until a buyer could optimize the business. Based on management's internal modeling at the culmination of the due diligence process, management determined this cash payment to be $700.0 million. Management intends to reduce the negative cash flow of the Cogent Fiber Business through the payments from the IP Transit Services Agreement, by reducing operating costs and by increasing revenue primarily by providing optical wavelength and optical transport services. We are selling these services to our existing customers, customers we acquired with the Cogent Fiber Business and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. Our cash flow requirements related to the acquisition of the Cogent Fiber Business will be dependent upon our ability to reduce the acquired operating costs, our success in retaining the profitable acquired customers and our ability to sell optical wavelength and optical transport services over our Optical Wave Network.

Under the IP Transit Services Agreement, TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments of $29.2 million per month during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments of $8.3 million per month over the subsequent 42 months. Through March 31, 2026, we received monthly payments totaling $533.3 million under the IP Transit Services Agreement, reflected as cash flows from investing activities in our consolidated statements of cash flows. As our business has grown as a result of an increasing customer base, the Transaction, broader geographic coverage and increased traffic on our network, we have historically produced a growing level of cash provided by operating activities. Since we closed the Transaction, we have experienced a reduction of cash provided by operating activities from the impact of the Transaction. The cash received from the IP Transit Services Agreement was designed to offset operating losses associated with the Cogent Fiber Business. Increasing our cash provided by operating activities is, in part, dependent upon our ability to reduce the operating costs of the Cogent Fiber Business while retaining its profitable revenue, expanding our geographic footprint and increasing our revenues from our wavelength and optical network services.

*Liquidity and cash obligations*

In assessing our liquidity, management reviews and analyzes our current cash balances, payments under the IP Transit Services Agreement, accounts receivable, accounts payable, accrued liabilities, capital expenditure commitments, and required finance lease and debt payments and other obligations.

We have had increasing success in raising capital by issuing notes and arranging financing and entering into leases that have had a lower cost and more flexible terms. The combination of our operating performance and access to capital has enhanced our financial flexibility and increased our ability to make distributions to stockholders in the form of cash dividends or through share

Page **37** of **46**

[**Table of Contents**](#TOC)

repurchases. Since our initial public offering, we have returned $1.8 billion to our stockholders through share repurchases and dividends. We will continue to assess our capital and liquidity needs and, where appropriate, return capital to our stockholders.

Over the next several years, we have significant contractual and anticipated cash outlays including our indicative dividend payments on our common stock, our maturing debt obligations, interest payments on our debt obligations and our projected capital expenditure requirements in order to help execute our business plan including the continued integration of the Cogent Fiber Business.

Our long-term debt interest obligations and maturity dates of our long-term debt obligations are as follows:

● Our $450.0 million 2027 Notes mature in June 2027 and include annual interest payments of $31.5 million until maturity,

● Our $300.0 million 2027 Mirror Notes mature in June 2027 and include annual interest payments of $21.0 million until maturity,

● Our $206.0 million Existing IPv4 Notes effectively mature in May 2029 (i.e., the interest rate will significantly increase if we do not pay them on the monthly payment date in May of 2029) and include annual interest payments of $16.3 million until such date (which amount increases if the Existing IPv4 Notes are not repaid prior to May 2029),

● Our $174.4 million New IPv4 Notes effectively mature in April 2030 (i.e., the interest rate will significantly increase if we do not pay them on the monthly payment date in April of 2030) and include annual interest payments of $11.6 million until such date (which amount increases if the New IPv4 Notes are not repaid prior to April 2030), and

● Our $600.0 million 2032 Notes mature in July 2032 and include annual interest payments of $39.0 million until maturity.

We may need to, or elect to, refinance all or a portion of our indebtedness at or before maturity, and we cannot provide assurances that we will be able to refinance any such indebtedness on commercially reasonable terms or at all. In addition, we may elect to secure additional capital in the future, at acceptable terms, to improve our liquidity or fund acquisitions or for general corporate purposes. In addition, in an effort to reduce future cash interest payments as well as future amounts due at maturity or to extend debt maturities, we may, from time to time, issue new debt, enter into interest rate swap agreements, enter into debt for debt, or cash transactions to purchase our outstanding debt securities in the open market or through privately negotiated transactions. We will evaluate any such transactions in light of the existing market conditions. The amounts involved in any such transaction, individually or in the aggregate, may be material. We or our affiliates may, at any time and from time to time, seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

In light of the economic uncertainties associated with the global economy, including due to the impact from tariffs and trade restrictions, the cash flow requirements of the Cogent Fiber Business, the lingering impact of the COVID-19 pandemic our executive officers and Board of Directors have continued to carefully monitor our liquidity and cash requirements. Based on current circumstances, we decreased our quarterly dividend to $0.02 per share of common stock for the dividend that was paid in the fourth quarter of 2025. Any future determination regarding dividends, including a decision to increase our quarterly dividend, will be at the discretion of the Board and will depend on the Company's financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends, and other factors the Board deems relevant. Given uncertainties regarding the potential impact of tariffs and trade restrictions, the global economy, lingering business impact of the pandemic, and the cash flow requirements of the Cogent Fiber Business, we will continue to monitor our capital spending. As we do each year, we will continue to monitor our future sources and uses of cash, and anticipate that we will adjust our capital allocation strategies when, as and if determined by our Board of Directors.

*Cash, cash equivalents and restricted cash*

As of March 31, 2026, we had cash, cash equivalents and restricted cash of $179.3 million. Restricted cash as of March 31, 2026 was $39.0 million. The net proceeds from our 2032 Notes, after the extinguishment and redemption of our 2026 Notes, were $92.8 million. The net proceeds of our $174.4 million New IPv4 Notes that we issued in April 2025 were $170.5 million of which

Page **38** of **46**

[**Table of Contents**](#TOC)

$72.6 was restricted. This restricted cash becomes available to us based upon improvements in our monthly leverage ratio and our debt service coverage ratio (as defined in the IPv4 Notes Indenture). During the three months ended March 31, 2026 and the year ended December 31, 2025, the restriction on $13.5 million and $26.9 million, respectively, of restricted cash was released primarily due to an improvement in our monthly leverage and debt service coverage ratios under the IPv4 Indenture. Under the Terms of the indenture, we have until October 2026 to satisfy the performance metrics and unlock the remaining restricted funds. Any amounts remaining on deposit in the prefunding account after October 2026 will be withdrawn and applied to prepay the April 2025 IPv4 Notes on a pro rata basis based on the initial principal amount.

We believe we are able to timely service our debt obligations. We believe we will have access to additional capital from a variety of sources and the public capital markets for debt and equity.

**Continued Impact of Changing Office Occupancy Rates**

While we believe that demand for office space in the buildings in which we operate will remain among the strongest in the markets in which they are located, and that most employers will eventually require their employees to return to their offices on at least a hybrid basis, the timing and scope of a return to office, particularly in a number of key markets we serve, remains uncertain. In some markets, office occupancy rates may never return to pre-2020 levels. As a result, we may continue to experience increased customer turnover, fewer upgrades of existing customer configurations and fewer new tenant opportunities. These trends may negatively impact our revenue growth, cash flows and profitability.

**Cash Flows**

The following table sets forth our consolidated cash flows:

---

| | | |
|:---|:---|:---|
| | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| <br>**(in thousands)** | **2026** | **2025** |
| Net cash provided by operating activities | $14834 | $36351 |
| Net cash used in investing activities | (21239) | (33088) |
| Net cash used in financing activities | (14655) | (57015) |
| Effect of exchange rates changes on cash | (4787) | 9806 |
| Net decrease in cash and cash equivalents and restricted cash | $(25847) | $(43946) |

---

*Net Cash Provided by Operating Activities.* Our primary source of operating cash is receipts from our customers who are billed on a monthly basis for our services. Our primary uses of operating cash are payments made to our vendors, payments to employees and interest payments made to our finance lease vendors and our note holders. Our changes in cash provided by operating activities are primarily due to changes in our operating profit and changes in our interest payments. Interest payments on our note obligations were $28.0 million and $4.1 million for the three months ended March 31, 2026 and 2025, respectively. Our Interest payments on our note obligations for the three months ended March 31, 2026 included our initial interest payment of $21.0 million on our 2032 Notes.

*Net Cash Used in Investing Activities.* Our primary use of cash for investing activities is for purchases of property and equipment. Purchases of property and equipment were $46.2 million and $58.1 million for the three months ended March 31, 2026 and 2025, respectively. The changes in purchases of property and equipment were primarily due to the timing and scope of our network expansion and reconfiguration activities including geographic expansion, purchases related to our acquisition of the Cogent Fiber Business, costs associated with providing wave services, conversion costs related to acquired data centers and adding buildings to our network. The reduction in purchases of property and equipment from the three months ended March 31, 2025 to the three months ended March 31, 2026 was primarily due to the completion of the conversion of the acquired data centers.

On the Closing Date, we entered into the IP Transit Services Agreement pursuant to which TMUSA will pay us an aggregate of $700.0 million, consisting of (i) $350.0 million in equal monthly installments during the first year after the Closing Date and (ii) $350.0 million in equal monthly installments over the subsequent 42 months. During the three months ended March 31, 2026 and 2025 we were paid $25.0 million and $25.0 million under the IP Transit Services Agreement, respectively.

*Net Cash Used in Financing Activities.* Our primary uses of cash for financing activities are for dividend payments, purchases of our common stock and principal payments under our finance lease obligations. Our primary sources of cash for financing activities

Page **39** of **46**

[**Table of Contents**](#TOC)

are issuances of note obligations. During the three months ended March 31, 2026 and 2025 we paid $1.3 million and $49.1 million for our quarterly dividend payments, respectively. In the fourth quarter 2025, we reduced our quarterly dividend payment to $0.02 per share. Principal payments under our finance lease obligations were $13.4 million and $8.0 million for the three months ended March 31, 2026 and 2025, respectively. Changes in our principal payments under our finance lease obligations were primarily due to the timing and extent of our network expansion and reconfiguration activities including geographic expansion, purchases related to our acquisition of the Cogent Fiber Business associated with providing wave services and adding buildings to our network.

**Cash Position and Indebtedness**

At March 31, 2026, our total indebtedness, at par, was $2.4 billion and our total cash, cash equivalents and restricted cash ($39.0 million) was $179.3 million. Our total indebtedness at March 31, 2026 includes $628.9 million of finance lease obligations for dark fiber under long-term IRU agreements.

**Stock Buyback Program**

Our Board of Directors has approved purchases of shares of our common stock under a buyback program (the "Buyback Program"). There were no purchases of our common stock in the three months ended March 31, 2026 or March 31, 2025. As of March 31, 2026, there was a total of $105.8 million available under the Buyback Program that is authorized to continue through December 31, 2026.

**Dividends on Common Stock and Return of Capital Program**

On May 1, 2026, our Board of Directors approved the payment of our quarterly dividend of $0.02 per common share. This estimated $1.0 million dividend payment is expected to be made on June 2, 2026.

The payment of any future dividends and any other returns of capital, including stock buybacks, will be at the discretion of our Board of Directors and may be reduced, eliminated or increased and will be dependent upon our financial position, results of operations, available cash, cash flow, capital requirements, limitations under our debt indentures and other factors deemed relevant by our Board of Directors. We are a Delaware Corporation and under the General Corporation Law of the State of Delaware, distributions may be restricted including a restriction that distributions, including stock purchases and dividends, do not result in an impairment of a corporation's capital, as defined under Delaware law. The indentures governing our notes limit our ability to return cash to our stockholders. See Note 3 of our interim condensed consolidated financial statements for additional discussion of limitations on distributions.

**Future Capital Requirements**

We believe that our cash on hand and cash generated from our operating activities and cash from the IP Transit Services Agreement will be adequate to meet our working capital, capital expenditure, debt service, dividend payments and other cash requirements for the next 12 months and beyond the next 12 months if we execute our business plan.

Any future acquisitions or other significant unplanned costs or cash requirements in excess of amounts we currently hold may require that we raise additional funds through the issuance of debt or equity. Our 2027 Notes and our 2027 Mirror Notes will mature in June 2027. At that time or earlier, we may elect to refinance or repay these notes which may require us to issue additional indebtedness. We cannot assure you that such financing will be available on terms acceptable to us or our stockholders, or at all. Insufficient funds may require us to delay or scale back the number of buildings and markets that we add to our network, reduce our planned increase in our sales and marketing efforts, reduce our planned dividend payments, or require us to otherwise alter our business plan or take other actions that could have a material adverse effect on our business, results of operations and financial condition. If issuing equity securities raises additional funds, substantial dilution to existing stockholders may result.

We may need to, or elect to, refinance all or a portion of our indebtedness at or before maturity and we cannot provide assurances that we will be able to refinance any such indebtedness on commercially reasonable terms or at all. In addition, we may elect to secure additional capital in the future, at acceptable terms, to improve our liquidity or fund acquisitions or for general corporate purposes. In addition, in an effort to reduce future cash interest payments as well as future amounts due at maturity or to extend debt maturities, we may, from time to time, issue new debt, enter into debt for debt, or cash transactions to purchase our outstanding debt securities in the open market or through privately negotiated transactions. We will evaluate any such transactions in light of the existing market conditions. The amounts involved in any such transaction, individually or in the aggregate, may be material.

*Off-Balance Sheet Arrangements*

We do not have relationships with unconsolidated entities or financial partnerships, such as entities often 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. In addition, we do not engage in trading activities involving non-exchange traded contracts. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in these relationships.

**Critical Accounting Estimates**

Management believes that as of March 31, 2026, there have been no material changes to our critical accounting policies and significant estimates from those listed in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our annual report on Form 10-K for the year ended December 31, 2025.

**ITEM 3.** **QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

**ITEM 4.** **CONTROLS AND PROCEDURES.**

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and 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, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), an evaluation was performed under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based upon that evaluation, our management, including our principal executive officer and our principal financial officer, concluded that the design and operation of our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.

There has been no change in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
