(1) In connection with the acquisition of 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 "Wireline Business"), Cogent began to provide optical wavelength services and optical transport services over its fiber network.

(2) Consists of legacy services of companies whose assets or businesses were acquired by Cogent.

(3) See Schedules of Non-GAAP measures below for definitions and reconciliations to GAAP measures.

(4) Network operations expense excludes equity-based compensation expense of $490, $506, $570, $319, $319 and $97 in the three-month periods ended March 31, 2025 through June 30, 2026 respectively. Network operations expense includes excise taxes, including Universal Service Fund fees, of $20,200, $19,998, $19,188, $19,786, $19,490 and $18,889 in the three-month periods ended March 31, 2025 through June 30, 2026, respectively.

(5) In connection with the acquisition of the Wireline Business, Cogent classified revenue and customer connections as follows:

(6) GAAP gross profit is defined as total service revenue less network operations expense, depreciation and amortization and equity-based compensation included in network operations expense. GAAP gross margin is defined as GAAP gross profit divided by total service revenue.

(7) Non-GAAP gross profit represents service revenue less network operations expense, excluding equity-based compensation and amounts shown separately (depreciation and amortization expense). Non-GAAP gross margin is defined as non-GAAP gross profit divided by total service revenue. Management believes that non-GAAP gross profit and non-GAAP gross margin are relevant measures to provide investors. Management uses them to measure the margin available to the company after network service costs, in essence a measure of the efficiency of the Company's network.

(8) Excludes equity-based compensation expense of $7,523, $4,158, $8,362, $4,489, $7,244 and $7,545 in the three-month periods ended March 31, 2025 through June 30, 2026, respectively.

(9) Through February 5, 2026, Cogent was party to an interest rate swap agreement (the "Swap Agreement") that has the economic effect of modifying the fixed interest rate obligation associated with its Senior Secured 2026 Notes to a variable interest rate obligation based on the Secured Overnight Financing Rate ("SOFR") so that the interest payable on Cogent's 2026 Notes effectively became variable based on overnight SOFR. Interest expense includes payments of $9,880 and $4,078 for the three-month periods ended December 31, 2025 and March 31, 2026, respectively, related to the Swap Agreement. Under GAAP, changes in the valuation of the Swap Agreement are classified with interest expense in the condensed consolidated statements of comprehensive income (loss).

(10) Includes cash payments under the IP Transit Services Agreement, as discussed above, of $25.0 million for each of the periods from March 31, 2025 to June 30, 2026. The $8.3 million monthly payment for July 2026 was received on June 30, 2026 and excluded from EBITDA, as adjusted for the three months ended June 30, 2026 since it relates to the three months ended September 30, 2026.

(11) In connection with the acquisition of the Wireline Business, Cogent acquired 482 technical buildings. Cogent converted 52 of those buildings to Cogent Data Centers and 87 into Cogent Edge Data Centers.

(12) In connection with the acquisition of the Wireline Business, Cogent hired 942 total employees, including 75 quota bearing sales employees and 114 sales employees.

(13) Net-centric revenue under the commercial agreement (the "CSA") with TMUSA for colocation and connectivity services(predominantly on-net revenue) was

Net-centric customer connections under the CSA were:

(14) Amounts Due from T-Mobile include 1) Due from T-Mobile, IP Transit Services Agreement, current portion, 1) Due from T-Mobile, IP Transit Services Agreement, long-term portion and 3) Due from T-Mobile, Purchase Agreement, all amounts net of their applicable discounts. These amounts totaled $265,090, $244,821, $224,167, $203,120, $181,670 and $151,479 as of March 31, 2025 to June 30, 2026, respectively.

(15) The $8.3 million cash payment under the IP Transit Services Agreement for July 2026 was received on June 30, 2026 and excluded from EBITDA, as adjusted for the three months ended June 30, 2026 since it relates to the three months ended September 30, 2026.

Schedules of Non-GAAP Measures

EBITDA, EBITDA, as adjusted for cash payments made to the Company under the IP Transit Services Agreement, EBITDA margin and EBITDA, as adjusted for cash payments made to the Company under the IP Transit Services Agreement, margin

EBITDA represents net cash flows provided by operating activities plus changes in operating assets and liabilities, cash interest expense and cash income tax expense. Management believes the most directly comparable measure to EBITDA calculated in accordance with generally accepted accounting principles in the United States, or GAAP, is net cash provided by operating activities. The Company also believes that EBITDA is a measure frequently used by securities analysts, investors, and other interested parties in their evaluation of issuers. EBITDA, as adjusted for cash payments under the IP Transit Services Agreement with T-Mobile, represents EBITDA and cash payments made to the Company under the IP Transit Agreement. EBITDA margin is defined as EBITDA divided by total service revenue. EBITDA, as adjusted for cash payments made to the Company under the IP Transit Agreement margin is defined as EBITDA, as adjusted for cash payments made to the Company under the IP Transit Agreement, divided by total service revenue.

The Company believes that EBITDA, EBITDA, as adjusted for cash payments made to the Company under the IP Transit Services Agreement, EBITDA margin and EBITDA as adjusted for cash payments made to the Company under the IP Transit Services Agreement margin are useful measures of its ability to service debt, fund capital expenditures, pay dividends and expand its business. The company believes its EBITDA, as adjusted for cash payments made to the Company under the IP Transit Services Agreement, is a useful measure because it includes recurring cash flows stemming from the IP Transit Services Agreement that are of the same type as contracted payments under commercial contracts. The measurements are an integral part of the internal reporting and planning system used by management as a supplement to GAAP financial information. EBITDA, EBITDA, as adjusted for cash payments made to the Company under the IP Transit Agreement, EBITDA margin and EBITDA as adjusted for cash payments made to the Company under the IP Transit Agreement margin are not recognized terms under GAAP and accordingly, should not be viewed in isolation or as a substitute for the analysis of results as reported under GAAP, but rather as a supplemental measure to GAAP. For example, these measures are not intended to reflect the Company's free cash flow, as they do not consider certain current or future cash requirements, such as capital expenditures, contractual commitments, and changes in working capital needs, interest expenses and debt service requirements. The Company's calculations of these measures may also differ from the calculations performed by its competitors and other companies and as such, their utility as a comparative measure is limited.

EBITDA, and EBITDA, as adjusted cash payments made to the Company under the IP Transit Services Agreement, are reconciled to net cash provided by operating activities in the table below.

Non-GAAP gross profit represents service revenue less network operations expense, excluding equity-based compensation and amounts shown separately (depreciation and amortization expense). Non-GAAP gross margin is defined as non-GAAP gross profit divided by total service revenue. Management believes that non-GAAP gross profit and non-GAAP gross margin are relevant measures for investors, as they are metrics that management uses to measure the margin and amount available to the Company after network service costs, in essence, these are measures of the efficiency of the Company's network.

Gross and Net Leverage Ratios

Gross leverage ratio is defined as total debt divided by the trailing 12 months EBITDA, as adjusted for cash payments under the IP Transit Services Agreement. Net leverage ratio is defined as total net debt (total debt minus cash and cash equivalents) divided by the last 12 months EBITDA, as adjusted for cash payments under the IP Transit Services Agreement. Gross leverage, adjusted for amounts Due from T-Mobile, is defined as total debt minus amounts due from T-Mobile divided by the last 12 months EBITDA, as adjusted for cash payments under the IP Transit Services Agreement. Net leverage, adjusted for amounts Due from T-Mobile, is defined as total net debt (total debt minus cash and cash equivalents) minus amounts due from T-Mobile divided by the last 12 months EBITDA, as adjusted for cash payments under the IP Transit Services Agreement.

Secured Leverage Ratio is defined in the Company's Indentures as total secured debt divided by Consolidated Cash Flow for the Reference Period, subject to certain adjustments provided for in the Company's Indentures.

Such statements include, but are not limited to statements identified by words such as "believes," "expects," "anticipates," "estimates," "intends," "plans," "targets," "projects" and similar expressions. The statements in this release are based upon the current beliefs and expectations of Cogent's management and are subject to significant risks and uncertainties. Actual results may differ from those set forth in the forward-looking statements. Numerous factors could cause or contribute to such differences, including the impact of our acquisition of the Wireline Business, including our difficulties integrating our business with the acquired Wireline Business, which may result in the combined company not operating as effectively or efficiently as expected; transition services required to support the acquired Wireline Business and the related costs continuing for a longer period than expected; transition related costs associated with the acquisition;; 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, a contraction of the capital markets, which could affect spending on Internet services and our ability to engage in financing activities; the impact of changing foreign exchange rates (in particular the Euro to USD and Canadian dollar to USD exchange rates) on the translation of our non-USD denominated revenues, expenses, assets and liabilities; legal and operational difficulties in new markets; 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 net neutrality rules by the United States Federal Communications Commission and in the area of data protection; cyber-attacks or security breaches of our network; 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 arrangements and right-of-way agreements on favorable terms; our reliance on a few equipment vendors, and the potential for hardware or software problems associated with such equipment; 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 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 December 31, 2025 and our Form 10-Q for the quarterly periods ended March 31, 2025, June 30, 2025, September 30, 2025, March 31, 2026 and June 30, 2026.
