(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 $385, $350, $469, $477 and $490 in the three-month periods ended March 31, 2024 through March 31, 2025 respectively. Network operations expense includes excise taxes, including Universal Service Fund fees, of $20,549, $19,182, $19,752, $20,960 and $20,200 in the three-month periods ended March 31, 2024 through March 31, 2025, respectively.

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

· $12.9 million of the Wireline Business monthly recurring revenue and 17,823<br>customer connections as corporate revenue and corporate customer connections, respectively,
· $6.5 million of monthly recurring revenue and 5,711 customer connections<br>as net-centric revenue and net-centric customer connections, respectively, and
· $20.1 million of monthly recurring revenue and 23,209 customer connections<br>as enterprise revenue and enterprise customer connections, respectively.

(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 $6,565, $3,215, $7,406, $6,871 and $7,523 in the three-month periods ended March 31, 2024 through March 31, 2025, respectively and excludes $9,037 and $12,370 of Sprint acquisition costs for the three-month periods ended March 31, 2024 and June 30, 2024, respectively. There were no Sprint acquisition costs for the three months ended September 30, 2024, December 31, 2024 or March 31, 2025.

(9) As of March 31, 2025, 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 the 2026 Notes effectively became variable based on overnight SOFR. Interest expense includes payments of $12,122 and $12,081 for the three-month periods ended June 30, 2024 and December 31, 2024, 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 (loss) income.

Schedules of Non-GAAP Measures

EBITDA, EBITDA, as adjusted for Sprint acquisition costs andcash payments made to the Company under the IP Transit Services Agreement, EBITDA margin and EBITDA, as adjusted for Sprint acquisitioncosts and 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 Sprint acquisition costs and cash payments under the IP Transit Services Agreement with T-Mobile, represents EBITDA plus costs related to the Company’s acquisition of the Wireline Business 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 Sprint acquisition costs and cash payments made to the Company under the IP Transit Agreement margin is defined as EBITDA, as adjusted for Sprint acquisition costs and 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 Sprint acquisition costs and cash payments made to the Company under the IP Transit Services Agreement, EBITDA margin and EBITDA as adjusted for Sprint acquisition costs and 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 Sprint acquisition costs and 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 Sprint acquisition costs and cash payments made to the Company under the IP Transit Agreement, EBITDA margin and EBITDA as adjusted for Sprint acquisition costs and 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.

Non-GAAP Gross Profit (6) $ 97,620 $ 104,626 $ 96,119 $ 97,585 $ 110,099
GAAP Gross Margin (5) 9.9 % 11.6 % 3.8 % 11.8 % 13.6 %
Non-GAAP Gross Margin (6) 36.7 % 40.2 % 37.4 % 38.7 % 44.6 %

(5) 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.

(6) 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 measures 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.
