PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

(1) Summary of Significant Accounti ng Policies:

a) Description of Business:

Frontier Communications Parent, Inc. is a provider of communications services in the United States, with approximately 3.2 million broadband subscribers and approximately 12,800 employees, operating in 25 states as of June 30, 2025. We were incorporated in 1935, originally under the name of Citizens Utilities Company. Frontier and its subsidiaries are referred to herein as “we,” “us,” “our,” “Frontier,” or the “Company” in this report.

b)Basis of Presentation and Use of Estimates:

Our interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2024. The consolidated financial statements include the accounts of Frontier Communications Parent, Inc., all consolidated subsidiaries and variable interest entities of which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary, in the opinion of Frontier’s management, to present fairly the results for the interim periods shown. Revenues, net income, and cash flows for any interim periods are not necessarily indicative of results that may be expected for the full year.

We operate in one reportable segment. Frontier provides both regulated and unregulated voice, data and video services to consumer, business, and wholesale customers and is typically the incumbent voice services provider in its service areas. Certain reclassifications of prior period balances have been made to conform to the current period presentation. For our interim financial statements as of and for the period ended June 30, 2025, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-Q with the Securities and Exchange Commission (“SEC”).

The preparation of our financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities at the date of the financial statements, (ii) the disclosure of contingent assets and liabilities, and (iii) the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. Estimates and judgments are used when accounting for the application of allowance for credit losses, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, and pension and other postretirement benefits, among others.

c) Going Concern:

In accordance with the requirements of Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements Going Concern (ASU 2014-15)”, and ASC 205, “Presentation of Financial Statements”, we have the responsibility to evaluate at each reporting period, including interim periods, whether conditions and/or events raise substantial doubt about our ability to meet our future financial obligations. In its evaluation of this report, management considered our current financial condition and liquidity sources, including current funds available, forecasted future cash flows and our conditional and unconditional obligations due within one year following the date of issuance of this Quarterly Report on Form 10-Q.

We believe we have the ability to meet our obligations for at least one year from the date of issuance of this Form 10-Q. Accordingly, the accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern and contemplate the realization of assets and the satisfaction of liabilities in the normal course of business.

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

d)Cash Equivalents and Restricted Cash:

We consider all liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash amounts represent cash collateral required for certain Letter of Credit obligations and utility vendors and collateral for debt arrangements.

At June 30, 2025 and December 31, 2024, the Company had $152 million and $161 million, respectively, in restricted cash on our consolidated balance sheet. Pursuant to the terms of the Company’s secured fiber network revenue term notes, and secured fiber network revenue variable funding note facility, as described in Note 9, restricted cash is held in securitization escrow accounts. As of June 30, 2025 and December 31, 2024, approximately $93 million and $56 million, respectively, is current restricted cash held for the purpose of paying interest and certain fees. This current restricted cash is included within the line item “Income taxes and other current assets” on our consolidated balance sheet. In addition, as of June 30, 2025 and December 31, 2024, we had approximately $59 million and $105 million, respectively, in noncurrent restricted cash held for the purpose of satisfying the required liquidity reserve amount. This non-current restricted cash is included within the line item “other assets” on our consolidated balance sheet.

e) I nvestments:

Short-term Investments

Given the long-term nature of our fiber build, we may invest cash into short-term investments to improve interest income while preserving funding flexibility.

As of June 30, 2025 and December 31, 2024, the Company had no short-term investments.

Other Investments

In connection with the closing of the securitization transaction, approximately $63 million in the form of U.S. Treasuries was deposited in an escrow account established with a trustee, for the purpose of paying interest and principal on $47 million principal amount in remaining debt of our subsidiary Frontier Southwest Incorporated. As of June 30, 2025 and December 31, 2024, this balance was approximately $55 million and $57 million, respectively, and is included in “Other assets” on our consolidated balance sheets and is restricted. See Note 9 for further details.

f) Revenue Recognition:

##### Revenue for data and Internet services, voice services, video services, and switched and non-switched access services is recognized as services are provided to customers. Services that are billed in advance include monthly recurring network access services (including data services), special access services, and monthly recurring voice, video, and related charges. Revenue is recognized by measuring progress toward the complete satisfaction of our performance obligations. The unearned portion of these fees is deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Services that are billed in arrears include non-recurring network access services (including data services), switched access services, and non-recurring voice and video services. The earned but unbilled portion of these fees is recognized as revenue in our consolidated statements of operations and accrued in “Accounts receivable” on our consolidated balance sheet in the period that services are provided. Excise taxes are recognized as a liability when billed.

(Unaudited)

Satisfaction of Performance Obligations

We satisfy our obligations to customers by transferring goods and services in exchange for consideration received from the customer. The timing of our satisfaction of the performance obligation may differ from the timing of the customer’s payment.

Bundled Service and Allocation of Discounts

When customers purchase more than one service, revenue for each is determined by allocating the total transaction price based upon the relative stand-alone selling price of each service. We frequently offer service discounts as an incentive to customers, which reduce the total transaction price. Any incentives which are considered cash equivalents (e.g. gift cards) that are granted will similarly result in a reduction of the total transaction price. Cash equivalent incentives are accounted for on a portfolio basis and are recognized in the month they are awarded to customers.

Customer Incentives

In the process of acquiring and/or retaining customers, we may issue a variety of incentives aside from service discounts or cash equivalent incentives. Those incentives that have stand-alone value (e.g. gift cards not considered cash equivalents or free goods/services) are considered separate performance obligations. While these incentives are free to the customer, a portion of the consideration received from the customer is ascribed to them based upon their relative stand-alone selling price. These types of incentives are accounted for on a portfolio basis with both revenue and expense recognized in the month they are awarded to the customer. The earned revenue associated with these incentives is reflected in “Other” revenue while the associated costs are reflected in “Cost of Services”.

Upfront Fees

All non-refundable upfront fees assessed to our customers provide them with a material right to renew; therefore, they are deferred by creating a contract liability and amortized into “Data and Internet service revenue” for fees charged to our wholesale customers and “Other revenue” for fees charged to all other customers over the average customer life using a portfolio approach.

Customer Acquisition Costs

Sales commission expenses are recognized as incurred. According to ASC 606, incremental costs in obtaining a contract with a customer are deferred and recorded as a contract asset if the period of benefit is expected to be greater than one year. For our retail customers, this period of benefit has been determined to be less than one year. As such, we applied the practical expedient that allows such costs to be expensed as incurred.

Taxes, Surcharges and Subsidies

We collect various taxes, Universal Service Funds (“USF”) surcharges (primarily federal USF), and certain other surcharges from our customers and subsequently remits these taxes to governmental authorities.

In June 2015, we accepted the FCC offer of support to price cap carriers under the Connect America Fund (“CAF”) Phase II program, which was intended to provide long-term support for broadband build commitments in high cost unserved or underserved areas. The seven-year funding term ended on December 31, 2021. The Universal Service Administrative Company (“USAC”) and the FCC are reviewing carriers’ CAF II program completion data, and if USAC or the FCC determines that we did not satisfy certain applicable CAF Phase II requirements, we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations.

In May 2022, we accepted the FCC offer under the Rural Digital Opportunity Fund (“RDOF”) Phase I program, which provides funding over a ten-year period to support the construction of broadband networks in rural communities across the country. We accepted $37 million in annual support through 2032 in return for our commitment to make broadband available to households within the RDOF eligible areas. We will recognize the FCC’s RDOF Phase I subsidies into revenue on a straight-line basis over the ten-year funding

term which will end March 31, 2032. We are required to complete the RDOF deployment meeting certain annual milestones starting in December 31, 2025 through December 31, 2028. Thereafter, USAC and the FCC will review carriers’ RDOF program completion data, and if USAC or the FCC determines that we did not satisfy applicable FCC RDOF requirements, funding provided to us can be discontinued and we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations. Fines and penalties could also be assessed to the extent Frontier were ever to decide to surrender RDOF locations previously awarded. We accrue for any potential shortfall in the household build commitment that we deem to be probable and reasonably estimated.

On July 24, 2024, the U.S. Court of Appeals for the Fifth Circuit held that certain delegations of authority in the USF contribution system are unconstitutional. The court remanded the case to the FCC. The Fifth Circuit subsequently stayed the decision to allow the FCC to file a petition with the U.S. Supreme Court seeking review. The stay allowed for the continued collection of USF contributions while the Supreme Court considered the case. On June 27, 2025 the Supreme Court issued its opinion and upheld the legality of the current USF framework.

g)Property, Plant and Equipment:

Property, plant and equipment are stated at original cost, including capitalized interest. Maintenance and repairs are charged to operating expenses as incurred. The gross book value of routine property, plant and equipment retired is charged against accumulated depreciation.

h)Definite Lived Intangible Assets:

Intangible assets are initially recorded at estimated fair value. Customer relationship intangibles were established for business and wholesale customers. These intangibles are amortized on a straight-line basis over their assigned useful lives of between 11 and 16 years. Additionally, trademark and tradename assets established upon emergence are amortized on a straight-line basis over 5 years. We review such intangible assets annually, or more often if indicators of impairment arise, to determine whether there is evidence that indicates an impairment condition may exist that would necessitate a change in useful life and a different amortization period.

(i)Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of:

We review long-lived assets to be held and used, including customer lists and property, plant and equipment, and long-lived assets to be disposed of for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of the asset to the future undiscounted net cash flows expected to be generated by the asset. Recoverability of assets held for sale is measured by comparing the carrying amount of the assets to their estimated fair market value. If any assets are considered to be impaired, the impairment is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value. Also, we periodically reassess the useful lives of our long-lived assets to determine whether any changes are required.

j)Lease Accounting:

We determine if an arrangement contains a lease at inception. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating and Finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating and finance lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms used in accounting for leases may reflect options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term. ROU assets for operating leases are recorded to “Other Assets”, and the related liabilities recorded to “Other current liabilities”, and “Other liabilities” on our

9

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

consolidated balance sheets. Assets subject to finance leases are included in “Property, Plant & Equipment”, with corresponding liabilities recorded to “Other current liabilities”, and “Other liabilities” on our consolidated balance sheets.

We assess potential impairments to our leases annually, or as indicators exist, if indicators of impairment arise to determine whether there is evidence that indicate an impairment condition may exist.

k) Income Taxes and Deferred Income Taxes:

We file a consolidated federal income tax return. We utilize the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recorded for the tax effect of temporary differences between the financial statement basis and the tax basis of assets and liabilities using tax rates expected to be in effect when the temporary differences are expected to reverse.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, tax-planning strategies, and results of recent operations. If we determine that we are not able to realize a portion of our net deferred tax assets in the future, we would make an adjustment to the deferred tax asset valuation allowance, which would increase the provision for income taxes.

The tax effect of a change in tax law or rates included in income tax expense from continuing operations includes effect of changes in deferred tax assets and liabilities initially recognized through a charge or credit to other comprehensive income. The residual tax effects typically are released when the item giving rise to the tax effect is disposed of, liquidated, or terminated.

l) Stock Plans:

We have one active stock-based compensation plan under which grants are made and awards remain outstanding. Awards under this plan may be made to employees, directors or consultants of the Company or its affiliates, as determined by the Compensation and Human Capital Committee of the Board. Awards may be made in the form of restricted stock, restricted stock units, incentive stock options, non-qualified stock options, stock appreciation rights or other stock-based awards, including awards with performance, market, and time-vesting conditions. See Note 12 for further details.

The compensation cost recognized is based on awards ultimately expected to vest. GAAP requires forfeitures to be estimated and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

(2) Merger Agreement:

On September 4, 2024, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Verizon Communications Inc., a Delaware corporation (“Verizon”), and France Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Verizon (“Merger Sub”), pursuant to which, subject to the satisfaction or waiver (to the extent permitted by law) of specified conditions, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Verizon.

Subject to the terms and conditions of the Merger Agreement, which has been unanimously approved by the Board, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of the Company issued and outstanding as of immediately prior to the Effective Time (subject to certain exceptions set forth in the Merger Agreement) shall be converted into the right to receive $38.50 in cash, without interest (the “Merger Consideration”).

10

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

At the Effective Time, other than as set forth below, each outstanding RSU and PSU will vest and be canceled and the holder thereof will be entitled to receive an amount in cash equal to the number of shares of Company Common Stock underlying such award (in the case of PSUs, based on attainment of all applicable performance goals at the greater of target and actual level of performance measured at the Effective Time) multiplied by the Merger Consideration. At the Effective Time, a portion of the outstanding RSUs and PSUs granted following the date of the Merger Agreement (determined by proration of any such grant based on the time remaining between the Effective Time and the end of the relevant vesting period) shall be automatically converted into a number of unvested restricted stock units of Verizon (“Verizon RSUs”) equal to the number of such RSUs and PSUs multiplied by an exchange ratio equal to the Merger Consideration divided by the five day volume weighted average price of Verizon common stock ending with the second complete trading day immediately prior to the closing date. Such conversion of PSUs shall be based on attainment of all applicable performance goals at the greater of target and actual level of performance measured at the Effective Time. The Verizon RSUs shall be subject to the same terms and conditions as applied to the RSUs and PSUs of the Company (including time-based vesting conditions but excluding performance-based vesting conditions) prior to the Effective Time.

The consummation of the Merger is subject to certain closing conditions, including, among other things: (i) the approval of the holders of a majority of the voting power represented by the outstanding shares of Company Common Stock entitled to vote thereon (the “Company Stockholder Approval”); (ii) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (iii) the receipt of certain required consents or approvals from the FCC and certain specified state regulatory authorities; (iv) the absence of legal restraints prohibiting the Merger; and (v) other customary conditions specified in the Merger Agreement. The transaction is not subject to a financing condition. The Company Stockholder approval was obtained on November 13, 2024, and the applicable HSR waiting period expired on February 14, 2025. The FCC approved the transaction on May 16, 2025. Subject to such remaining conditions, the Company expects to consummate the merger by the first quarter of 2026.

The Merger Agreement contains certain termination rights for the Company and Verizon, including, among others, the right of either party to terminate the Merger Agreement if the Merger is not consummated by March 4, 2026 (subject to two automatic three-month extensions if certain closing conditions have not been satisfied).

Upon termination of the Merger Agreement under specified circumstances, the Company will be required to pay Verizon a termination fee equal to $320 million. Additionally, upon termination of the Merger Agreement under specified circumstances relating to the failure to obtain certain specified antitrust or other regulatory approvals, Verizon will be required to pay the Company a termination fee equal to $590 million.

The Company has incurred and will incur certain costs relating to the proposed Merger, such as financial advisory, legal, accounting and other professional services fees.

(3) Recent Accounting Pronouncements:

Financial Accounting Standards Not Yet Adopted

ASU No. 2024-03 – Income Statement – Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. This update requires public business entities to provide detailed disclosures in the notes to financial statements, disaggregating specific expense categories within relevant income statement captions. The required categories include purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depreciation, intangible asset amortization, and depletion. The standard is effective for annual reporting periods beginning after December 15, 2026, and for interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

ASU No. 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments

in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income [or loss] by the applicable statutory income tax rate). For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on its related disclosure.

(4) Revenue Recognition:

We categorize our products, services, and other revenues into the following categories:

Data and Internet services include broadband services for consumer and business customers. We provide data transmission services to high volume business customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”);

Voice services include traditional local and long-distance wireline services, Voice over Internet Protocol (VoIP) services, as well as a number of unified messaging services offered to our consumer and business customers. Voice services also include the long-distance voice origination and termination services that we provide to our business customers and other carriers;

Video services include revenues generated from traditional television (TV) services provided directly to consumer customers as well as satellite TV services provided through various satellite providers, and through partnerships with over-the-top (OTT) video providers. Video services also includes pay-per-view revenues, video on demand, equipment rentals, and video advertising. We have made the strategic decision to limit sales of new traditional TV services, focusing on our broadband products and OTT video options;

Other customer revenue includes switched access revenue, rents collected for collocation services, and other services and fees. Switched access revenue includes revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long-distance voice traffic. These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies; and

Subsidy and other regulatory revenue include revenues generated from cost subsidies from state and federal authorities, including RDOF.

The unsatisfied obligations for retail customers consist of amounts in advance billings, which are expected to be earned within the following monthly billing cycle. Unsatisfied obligations for wholesale customers are based on a point-in-time calculation and determined by the number of circuits provided and the contractual price. These wholesale customer obligations change from period to period based on new circuits added as well as circuits that are terminated.

The following table includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period:

| ($ in millions) |  | Revenue from contracts with customers |
| 2025 (remaining six months) |  | $ | 643 |
| 2026 |  |  | 130 |
| 2027 |  |  | 137 |
| 2028 |  |  | 83 |
| 2029 |  |  | 64 |
| Thereafter |  |  | 90 |
| Total |  | $ | 1,147 |

(5) Accounts Receivable:

The components of accounts receivable, net at June 30, 2025 and December 31, 2024 are as follows:

| ($ in millions) |  | June 30, 2025 |  | December 31, 2024 |
| Retail and Wholesale |  | $ | 446 |  | $ | 388 |
| Other |  |  | 51 |  |  | 57 |
| Less: Allowance for doubtful accounts |  |  | (67) |  |  | (66) |
| Accounts receivable, net |  | $ | 430 |  | $ | 379 |

We maintain an allowance for credit losses based on the estimated ability to collect accounts receivable. The allowance for credit losses is increased by recording an expense for the provision for bad debts for retail customers, and through decreases to revenue at the time of billing for wholesale customers. The allowance is decreased when customer accounts are written off, or when customers are given credits.

The provision for bad debts was $21 million and $20 million for the six months ended June 30, 2025 and 2024, respectively.

Approximately $858 million and $440 million of credits related to customers are included in other current liabilities on our consolidated balance sheets as of June 30, 2025, and December 31, 2024, respectively.

In accordance with ASC 326, we performed calculations to estimate expected credit losses, utilizing rates that are consistent with our write offs (net of recoveries) because such events affect the entity’s loss given default experience.

Activity in the allowance for credit losses for the three months ended June 30, 2025 was as follows:

| ($ in millions) |  |
| Balance at December 31, 2024 | $ | 66 |
| Provision for bad debt |  | 21 |
| Amounts charged to revenue |  | 8 |
| Write offs charged against the allowance |  | (28) |

The Revolving Facility is guaranteed by the same subsidiaries that guarantee the First Lien Notes. After giving effect to approximately $167 million of letters of credit outstanding, we had $758 million of available borrowing capacity under the Revolving Facility as of June 30, 2025.

The Revolving Facility includes customary negative covenants for loan agreements of this type, including covenants limiting Frontier and our restricted subsidiaries’ (other than certain covenants therein which are limited to subsidiary guarantors) ability to, among other things, incur additional indebtedness, create liens on assets, make investments, loans or advances, engage in mergers, consolidations, sales of assets and acquisitions, pay dividends and distributions and make payments in respect of certain material payment subordinated indebtedness, in each case subject to customary exceptions for loan agreements of this type.

Warehouse Facilities

On December 31, 2024 (the “Warehouse Effective Date”), Frontier Tampa Bay FL Fiber 1 LLC (the “Borrower”) and Frontier SPE FL Guarantor LLC, as guarantor (the “Warehouse Guarantor”), each a subsidiary of Frontier Communications Parent, Inc. (the “Parent”), entered into a credit agreement (the “Warehouse Credit Agreement”) with certain lenders that establishes and governs certain credit facilities (the “Warehouse Facilities”). The Warehouse Facilities include:

A delayed draw term loan facility (the “DDTL Facility”) of $1.5 billion, less commitments reserved for letters of credit (the “Maximum DDTL Amount”) and borrowed amounts. The DDTL Facility is available from the Warehouse Effective Date until the earlier of the full draw of the Maximum DDTL Amount or the third anniversary of the Warehouse Effective Date (such earlier date, the “DDTL Commitment Expiration Date”). To draw amounts under the DDTL Facility, the Borrower must comply with a total leverage ratio of no more than 6.75:1.00 and a debt service coverage ratio of at least 2.00:1.00. Additionally, no defaults or other specified conditions may be continuing, and all conditions precedent for each extension of credit must be satisfied. The Borrower must repay all outstanding amounts under the DDTL Facility due on the fifth anniversary of the Warehouse Effective Date. The interest rate for the DDTL Facility is either, at the

sole discretion of the Warehouse Borrower, for Base Rate Loans, (a) the highest of (i) the “U.S. Prime Lending Rate” published by the Wall Street Journal, (ii) the Federal Funds Effective Rate (as agreed to in good faith by the parties to the Warehouse Credit Agreement) plus 0.50%, and (iii) one-month Term SOFR plus 1.00% per annum, plus (b) 0.75%, with step-ups from and after the third anniversary, or, for SOFR Loans, Term SOFR plus 1.75%, with step-ups from and after the third anniversary.

An incremental term loan facility (the “Incremental Term Loan”) under which the Warehouse Borrower has the right to increase the commitments under the DDTL Facility by up to $750 million after the DDTL Commitment Expiration Date. No lender is required to increase its commitment. The Warehouse Borrower must comply with all representations and warranties, and the terms of any Incremental Term Loan must be identical to those of the DDTL Facilities, including maturity, priority of liens, prepayment terms, and pricing.

In the event of default, an additional 2.00% per annum will be applied to overdue amounts. Fees include commitment fees on undrawn portions, letter of credit fees, and fronting fees. The Warehouse Facilities are secured by first-priority pledges of equity interests and security interests in substantially all owned tangible and intangible assets of the Warehouse Borrower and its guarantors, which consist of the Warehouse Borrower’s fiber network assets and associated customer contracts in certain neighborhoods in the Tampa, Florida area.

On July 1, 2024, Frontier Issuer LLC (“Frontier Issuer”), a limited-purpose, bankruptcy remote, subsidiary of Frontier completed the issuance of $750 million aggregate principal amount of secured fiber network revenue term notes consisting of $530 million 6.19% Series 2024-1, Class A-2 term notes, $73 million 7.02% Series 2024-1, Class B term notes and $147 million 11.16% Series 2024-1, Class C term notes, each with an anticipated repayment term of seven years (collectively, the “Notes”). Collectively, the Notes have a weighted average yield of approximately 7.4%. The Notes are secured by certain of Frontier’s fiber assets and associated customer contracts in the North Texas area, in addition to those in the Dallas Metropolitan area contributed in the Series 2023-1 Notes offering. The assets of Frontier Issuer, AssetCo and the other securitization entities are available to satisfy only the obligations owed under the Fiber Term Notes and are not available to any other creditors of the Company or its affiliates. The Fiber Term Notes were issued pursuant to an indenture, dated as of August 8, 2023 (the “Base Indenture”), as supplemented by the Series 2023-1 Supplement thereto, dated as of August 8, 2023 (the “Series 2023-1 Supplement”), in each case entered into by and among the Issuer, Frontier Dallas TX Fiber 1 LLC (“AssetCo”) and Citibank, N.A. as the indenture trustee (the “Trustee”).

While the Fiber Term Notes are outstanding, scheduled payments of interest are required to be made on the Notes on a monthly basis. From and after the ARD, principal payments will also be required to be made on the Notes on a monthly basis. No principal payments will be due on the Fiber Term Notes prior to the ARD, unless certain rapid amortization or acceleration triggers are activated.

Secured Fiber Network Revenue Variable Funding Notes

On July 1, 2024, Frontier amended its Secured Fiber Network Revenue Variable Funding Notes, Series 2023-2, Class A-1, facility to reduce the available Variable Funding Notes commitment amount to $0, with the ability to increase the commitment amount up to $500 million in the future upon the satisfaction of certain conditions, and to extend the maturity date to June 2028.

In connection with entering into the DDTL Facility, the Company permanently reduced the Series 2023-2 Class A-1 Notes Maximum Principal Amount to $0, correspondingly reduced the Variable Funding Notes commitment amount to $0 and terminated the Series 2023-2 Class A-1 Note Purchase Agreement, in each case effective as of December 31, 2024.

(10) Restructuring and Other Charges:

Restructuring and other charges consists of severance and employee costs related to workforce reductions and costs associated with the Verizon merger and other restructuring activities.

During the six-month period ended June 30, 2025, we incurred $52 million in restructuring charges and other costs consisting of a minimal charge in pension/OPEB special termination benefit enhancements related to a voluntary separation program, $31 million of severance and employee costs resulting from workforce reductions, and $21 million primarily related to consulting and legal costs due to the Verizon merger and other restructuring activities.

During the six month period ended June 30, 2024, we incurred $60 million in restructuring charges and other costs consisting of $10 million in pension/OPEB special termination benefit enhancements related to a voluntary separation program, $18 million of severance and employee costs resulting from workforce reductions, and $32 million of costs related to other restructuring activities.

The following is a summary of the changes in the liabilities established for restructuring and related programs:

| ($ in millions) |  |  |  |
| Balance at January 1, 2025 |  | $ | 9 |
| Severance expense |  |  | 31 |

(11) Investment and Other Income, Net:

The components of investment and other income, net are as follows:

|  |  | For the three months ended ‎June 30, |  | For the six months ended ‎June 30, |
| ($ in millions) |  | 2025 |  | 2024 |  | 2025 |  | 2024 |
| Interest and dividend income |  | $ | 7 |  | $ | 20 |  | $ | 16 |  | $ | 38 |
| Pension benefit |  |  | 6 |  |  | 9 |  |  | 12 |  |  | 21 |

| Total investment and other income (loss), net |  | $ | 14 |  | $ | (24) |  | $ | 63 |  | $ | 88 |

Investment and other income, net increased by $38 million for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to a $72 million pension remeasurement loss during the three months ended June 30, 2024, partially offset by post-retirement remeasurement gain of $18 million in the prior-year quarter and a $13 million reduction in interest and dividend income, which reflected lower average cash and short-term investment balances during the current quarter.

Investment and other income, net decreased by $25 million for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This decrease was primarily attributable to a $35 million reduction in post-retirement remeasurement gain, a $22 million reduction in interest and dividend income, and a $9 million reduction in pension benefit, partially offset by a $42 million increase in pension remeasurement gain.

Pension and OPEB benefit (cost) consists of interest costs, expected return on plan assets, amortization of prior service (costs) and recognition of actuarial (gain) loss. Service cost components of pension and OPEB benefit costs are included in “Selling, general, and administrative expenses” on our consolidated statements of operations.

(12) Stock Plans:

Frontier Communications Parent, Inc. has one active long-term incentive plan, under which grants are made and awards remain outstanding: the 2024 Management Incentive Plan (the “2024 Incentive Plan”). The plan was approved by shareholders at the Annual Meeting on May 15, 2024, with 8,765,000 shares available for awards. The 2024 Incentive Plan permits stock-based awards to be made to employees, directors, or consultants of the Company or its affiliates, as determined by the Compensation and Human Capital Committee of the Board. Available shares under the previous plan of 1,151,334 were rolled into the new 2024 plan for a total of 9,916,334 shares reserved for issuance. Equity awards have been issued in the form of time-based restricted stock units (RSUs) and performance-based stock units (PSUs). As of June 30, 2025, there were 8,336,901 shares available to grant.

Restricted Stock Units

The following summary presents information regarding unvested restricted stock under the 2024 Incentive Plan:

|  |  |  | Weighted |  |  |  |
|  |  |  | Average |  |  |
|  | Number of |  | Grant Date |  | Aggregate |
|  | Shares |  | Fair Value |  | Fair Value |
|  | (in thousands) |  | (per share) |  | (in millions) |
Balance at January 1, 2025 |  | 2,058 |  | $ | 24.45 |  | $ | 71 |
Restricted stock units granted |  | 859 |  | $ | 35.88 |  | $ | 31 |
Restricted stock units vested |  | (720) |  | $ | 24.99 |  | $ | (26) |
Restricted stock units forfeited |  | (56) |  | $ | 25.19 |  |  |  |
Balance at June 30, 2025 |  | 2,141 |  | $ | 28.84 |  | $ | 78 |

For purposes of determining compensation expense, the fair value of each restricted stock grant is estimated based on the closing price of our common stock on the date of grant. The non-vested restricted stock units granted in 2023, 2024 and 2025 generally vest, and are expensed, on a ratable basis over three years from the grant date of the award. Total remaining unrecognized compensation cost associated with unvested restricted stock awards that is deferred at June 30, 2025 was $49 million and the weighted average vesting period over which this cost is expected to be recognized is approximately 2 years.

None of the restricted stock awards may be sold, assigned, pledged, or otherwise transferred, voluntarily or involuntarily, by the employees until the restrictions lapse, subject to limited exceptions. The restrictions are time-based. Compensation expense, recognized in “Selling, general, and administrative expenses”, of $16 million and $18 million for the six-month periods ended June 30, 2025, and 2024, respectively, has been recorded in connection with restricted stock.

Performance Stock Units

We currently have outstanding performance stock units (“PSU”) that were granted in 2023, 2024 and 2025. Under these awards, a target number of PSUs are granted to each participant with respect to a three-year performance period (“The Measurement Period”). For the 2025 PSU awards, for example, the Measurement Period is from January 1, 2025, through December 31, 2027.

The performance metrics under the 2025 PSU awards consist of (1) Adjusted Fiber EBITDA and (2) Fiber Revenue. Each performance metric is evenly weighted at 50% and the goals for both metrics have been fully set for the full Measurement Period.

The performance metrics under the 2024 PSU awards consist of (1) Adjusted Fiber EBITDA, (2) Fiber Revenue and (3) Relative Total Shareholder Return (“TSR”). Relative TSR is based on our total return to stockholders over the Measurement Period relative to the S&P 400 Mid Cap Index. Each performance metric is weighted 33.3% and the goals for each of the three metrics have been fully set for the full Measurement Period.

The performance metrics under the 2022 and 2023 PSU awards are (1) Adjusted Fiber EBITDA, (2) Fiber Locations Constructed and (3) Expansion Fiber Penetration with an overall relative TSR modifier. Each performance metric is weighted 33.3% and goals for each metric have been set for the full Measurement Period.

Achievement of the metrics for outstanding PSUs will be measured separately, and the number of awards earned will be determined based on actual performance relative to the targets of each performance metric. Achievement is measured on a cumulative basis for each performance metric individually at the end of the three-year Measurement Period with a TSR modifier for the 2023 plan. The payout of the 2023, 2024 and 2025 PSUs can range from 0% to a maximum award payout of 200% of the target units. The 2022 PSU awards paid out at 133.7% of target on February 28, 2025.

The number of PSUs earned at the end of the Measurement Period may be more or less than the number of target PSUs granted as a result of performance. An executive must maintain a satisfactory performance rating during the Measurement Period and, except for limited circumstances, must be employed by Frontier on the determination date in order for the award to vest. The Compensation and Human Capital Committee will determine the number of shares earned for the Measurement Period in the first quarter of the year following the end of the Measurement Period. PSU awards, to the extent earned, will be paid out in the form of common stock on a one-for-one basis.

Under ASC 718, Stock Based Compensation Expense, a grant date, and the fair value of a performance award are determined once the targets are finalized. For the 2023, 2024 and 2025 PSU awards, targets for all of the metrics have been fully set for each performance period and the related expense will be amortized over the appropriate performance period.

The following summary presents information regarding performance shares and changes during the period with regard to performance shares awarded under the 2024 Incentive Plan:

f |  |  |  |  |  |  |
|  |  |  |  | Weighted |  |
|  |  |  |  | Average |  |

(1) Represents the weighted average of the closing price of our stock on the date of the awards. |  |

For purposes of determining compensation expense, the fair value of each performance share grant is estimated based on the closing price of a share of our common stock on the date of the grant, adjusted to reflect the fair value of the relative TSR metric for the 2024 grant and TSR modifier for previous years. For both the six months ended June 30, 2025, and 2024, we recognized net compensation expense, reflected in “Selling, general, and administrative expenses,” of $12 million, and $18 million, respectively, related to PSU awards.

Converted PSUs

In 2024, approximately 501,000 PSUs of our CFO’s 2023-2025 PSUs converted into performance-based restricted stock subject to identical performance and service vesting conditions. There was no impact to the historical accounting treatment for these PSUs.

Non-Employee Directors

Compensation expense related to the board of directors, recognized in “Selling, general, and administrative expenses”, was less than $1 million for both the six months ended June 30, 2025 and 2024.

Frontier considered positive and negative evidence in regard to evaluating certain state deferred tax assets during the second quarter of 2025, including the development of recent years of pre-tax book losses. The state tax rate includes state valuation allowances. On the basis of this evaluation, a valuation allowance of $374 million ($295 million net of federal benefit) was recorded as of June 30, 2025.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted into law—legislation that makes many of the 2017 Tax Cuts and Jobs Act (“TCJA”) provisions permanent. The company will be evaluating the effects of the bill and will be reporting the effects of the bill in the third quarter.

| Total pension (benefit) cost |  | $ | 5 |  | $ | 78 |  | $ | (34) |  | $ | 10 |

The components of net periodic benefit cost other than the service cost component are included in “Investment and other income” on the consolidated statements of operations.

The value of our pension plan assets increased $99 million from $2,328 million at December 31, 2024 to $2,427 million at June 30, 2025. This increase primarily resulted from changes in the market value of investments of $119 million, net of plan expenses, and contributions of $62 million, offset by benefit payments to participants of $82 million.

As a result of special termination benefit enhancements related to a voluntary separation plan, Frontier remeasured its pension plan obligations, resulting in a remeasurement gain of $44 million for the six months ended June 30, 2025.

The pension plan contains provisions that provide certain employees with the option of receiving a lump sum payment upon retirement. Frontier’s accounting policy is to record these payments as a settlement only if, in the aggregate, they exceed the sum of the annual service and interest costs for the Pension Plan’s net periodic pension benefit cost.

In the first half of 2025, the Company recognized a minimal charge to reflect the cost of pension special termination benefit enhancements related to a voluntary separation plan, compared to a charge of $10 million as of June 30, 2024.

As a result of special termination benefit enhancements related to a voluntary separation plan, Frontier remeasured its postretirement benefit plan, resulting in a remeasurement gain of $18 million and $27 million for the three and six months ended June 30, 2024, respectively.

We capitalized $8 million and $8 million of pension and OPEB expense for the six months ended June 30, 2025 and 2024, respectively, into the cost of our capital expenditures, as the costs relate to our engineering and plant construction activities.

(17) Commitments and Contingencies:

We are party to various legal proceedings (including individual actions, class and putative class actions, and governmental investigations) arising in the normal course of our business covering a wide range of matters and types of claims including, but not limited to, general contract disputes, billing disputes, rights of access, taxes and surcharges, consumer protection, advertising, sales and the provision of services, intellectual property, including, trademark, copyright, and patent infringement, employment, regulatory, environmental, tort, claims of competitors and disputes with other carriers. Litigation is subject to uncertainty and the outcome of individual matters is not predictable. However, we believe that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which we are entitled, will not have a material adverse effect on our financial position, results of operations, or cash flows.

During the second quarter of 2025, Frontier accrued an incremental $66 million for legal disputes and settlements, primarily relating to the settlement of certain intellectual property disputes and pole attachment matters.

On October 22 and October 23, 2024, two complaints were filed in the Supreme Court of the State of New York, County of New York by purported Company stockholders against the Company, the Board, Verizon and Merger Sub in connection with the Merger. The complaints assert claims of negligent misrepresentation and concealment and negligence under New York common law. Among other remedies, the complaints seek an order enjoining the defendants from proceeding with the Merger unless and until the defendants disclose certain allegedly material information that was allegedly omitted from the proxy statements, rescinding the Merger to the extent already consummated or granting rescissory damages, awarding the plaintiffs costs and disbursements of the action, including reasonable attorneys’ and expert fees and expenses, and granting such other and further relief as the court may deem just and proper. Additional lawsuits arising out of the proposed Merger may also be filed in the

future. Furthermore, the Company has received demand letters from purported Company stockholders alleging disclosure deficiencies in the preliminary proxy statement and/or definitive proxy statement and demanding that the Company and the Board of Directors promptly issue corrective disclosures to cure the proxy statement prior to the anticipated stockholder vote on the proposed Merger. The Company believes that the allegations contained in the complaints and demands have no merit. We do not at this time consider there to be any reasonably possible material loss arising from the demands. There can be no assurance regarding the likelihood that the Company’s defense of any actions will be successful.

During the second quarter of 2024, Frontier reached a settlement with a net financial impact of $25 million resolving a dispute with the Chief Executive Officer of Frontier’s predecessor company, who left his position with the company in 2004, concerning split-dollar life insurance benefits granted during his employment.

In November 2021, Congress passed the IIJA which provides $65 billion to fund broadband connectivity programs, including broadband deployment to unserved and underserved locations. The National Telecommunications and Information Administration (NTIA) is administering the principal last mile infrastructure funding program in the amount of $42.5 billion, the Broadband Equity, Access & Deployment Program (BEAD), and will distribute funding through direct grants to states, who will then award the funds based on competitive grant programs. The NTIA has allocated approximately $25.5 billion to states in Frontier’s footprint. We participated in each of Frontier’s state challenge programs and pre-application and application processes. We are continuing to actively pursue awards of these stimulus funds; however, any awards that we ultimately receive under the IIJA may require significant up-front capital expenditures or other costs.

On June 6, 2025, NTIA issued a BEAD Restructuring Policy Notice to modify and replace certain requirements outlined in the BEAD Notice of Funding Opportunity. The Policy Notice rescinded all preliminary and provision subgrantee award selections and requires states to run at least one Benefit of the Bargain application round, in which minimal BEAD program outlay is the principal selection criteria. NTIA prohibited states from awarding additional points for 100% fiber projects but permitted them to prioritize “priority broadband projects” as that term is defined in the Infrastructure Investment and Jobs Act. The NTIA’s changes did not reduce the amount of funding allocated to each state for broadband infrastructure but eliminated certain potentially costly obligations associated with accepting BEAD awards, including middle-class affordability and low-cost offer pricing standards, open access, and climate change requirements, among others. It is uncertain if these changes will limit or impact Frontier’s participation in the BEAD program or its success in securing BEAD awards. We are closely tracking developments in this area, and additional revision to the program could have a material adverse effect on the BEAD program, any funding we receive and the costs of completing BEAD award projects.

On April 14, 2024, we detected that a third party had gained unauthorized access to portions of our information technology environment. Upon detection, the Company immediately activated its incident response plan, took action to contain the incident, launched an investigation with the assistance of leading cybersecurity experts, and notified law enforcement and applicable regulatory authorities. We worked with a leading e-discovery firm to undertake a thorough review of the impacted data to identify and provide notice to individuals whose information was impacted. Since the incident, the Company has also taken steps to further strengthen its information technology security. While the incident did not have a material impact on our financial condition or results of operations, the containment measures, which included shutting down certain of the Company’s systems, resulted in an operational disruption.

In October 2013, the California Attorney General’s Office notified certain Verizon companies, including one of the subsidiaries that we acquired in the CTF transaction, of potential violations of California state hazardous waste statutes primarily arising from the disposal of electronic components, batteries, and aerosol cans at certain California facilities. We have reached a settlement with the California Attorney General’s Office, which was approved by the court and paid by the Company in the second quarter 2025.

We accrue an expense for pending litigation when we determine that an unfavorable outcome is probable, and the amount of the loss can be reasonably estimated. Legal defense costs are expensed as incurred. None of our existing accruals for pending matters, after considering insurance coverage, is material. We monitor our pending litigation for the purpose of adjusting our accruals and revising our disclosures accordingly, when required. Litigation is, however, subject to uncertainty, and the outcome of any particular matter is not predictable. We will vigorously defend our interests in pending litigation, and as of this date, we believe that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which we are entitled, will not have a material adverse effect on our consolidated financial position, results of operations, or our cash flows.

In 2015, Frontier accepted the FCC’s CAF Phase II offer, which provided $313 million in annual support through 2021 in our current 25 states in return for the Company’s commitment to make broadband available to households within the CAF II eligible areas. The Company was required to complete the CAF II deployment by December 31, 2021. Thereafter, the FCC has been reviewing carriers’ CAF II program completion data, and if the FCC determines that the Company did not satisfy applicable FCC CAF Phase II requirements, Frontier could be required to return a portion of the funds previously received and may be subject to certain fines, requirements and obligations.

On January 30, 2020, the FCC adopted an order establishing the RDOF competitive reverse auction to provide support to serve high-cost areas. Under the FCCs RDOF Phase I auction, we were awarded approximately $371 million over ten years to build gigabit-capable broadband over a fiber-to-the-premises network to approximately 127,000 locations in eight states (California, Connecticut, Florida, Illinois, New York, Pennsylvania, Texas, and West Virginia). We began receiving RDOF funding in the second quarter of 2022 and we will be required to complete the buildout to the awarded locations by December 31, 2028, with interim annual target milestones starting December 31, 2025. To the extent Frontier is unable to fulfill the RDOF requirements, meet the milestones or construct to all locations by the required deadlines, funding to us could be discontinued and Frontier could be required to return a portion of funds previously received and may be subject to certain fines, requirements and obligations.

On July 24, 2024, the U.S. Court of Appeals for the Fifth Circuit held that certain delegations of authority in the USF contribution system are unconstitutional. The court remanded the case to the FCC. The Fifth Circuit subsequently stayed the decision to allow the FCC to file a petition with the U.S. Supreme Court seeking review. The stay allowed for the continued collection of USF contributions while the Supreme Court considered the case. On June 27, 2025 the Supreme Court issued its opinion and upheld the legality of the current USF framework.

We conduct certain of our operations in leased premises and lease certain equipment and other assets pursuant to operating leases. The lease arrangements have terms ranging from 1 to 99 years and several contain rent escalation clauses providing for increases in monthly rent at specific intervals. When rent escalation clauses exist, we record annual rental expense based on the total expected rent payments on a straight-line basis over the lease term. Certain leases also have renewal options. Renewal options that are reasonably assured are included in determining the lease term.

As of June 30, 2025, we had total “Accounts payable and accrued liabilities” of $1.2 billion, of which $968 million is related to accounts payable. As of December 31, 2024, we had total “Accounts payable and accrued liabilities” of $1.0 billion, of which $758 million is related to accounts payable.

Although from time to time we make short-term purchasing commitments to vendors with respect to capital expenditures, we generally do not enter into firm, written contracts for such activities. In connection with the fiber expansion build, we have prioritized diversifying our vendor base and solidifying partnership agreements with vendors for relevant labor and materials, to enable our build growth and customer expansion. Some of these key supplier agreements have multi-year terms and purchase commitments as we deem advisable in order to strengthen future supply. In addition, we have negotiated favorable payment terms with some of our vendors that allow for a longer payment period than our normal customary terms (referred to as vendor

financing), which are excluded from capital expenditures and reported as financing activities on the statement of cash flows. As of June 30, 2025, we had $0 million of vendor financing liabilities included in “Other current liabilities” on our consolidated balance sheets. For the six months ended June 30, 2025 we made $16 million in vendor financing payments related to capital expenditures.

We are party to contracts with several unrelated long-distance carriers. The contracts provide fees based on traffic they carry for us subject to minimum monthly fees.

Item 2.Management’s Discussion and Ana lysis of Financial Condition and Results of Operations

Frontier Communications Parent, Inc. is a leading communications and technology provider offering broadband services to approximately 3.2 million broadband customers, with approximately 12,800 employees, operating in 25 states as of June 30, 2025. We are building critical infrastructure across the country with our fiber-optic network and cloud-based solutions, enabling secure high-speed connections. Driven by our purpose of Building Gigabit America TM, we are focused on supporting a digital society, closing the digital divide, and working toward a more sustainable environment.

Business Overview

In 2020, we began the expansion and transformation of our fiber network to meet the rapidly increasing demand for data from our consumer and business customers. We believe that a fiber network has competitive advantages to meet this growing demand, including faster download speeds, faster upload speeds, and lower latency levels than alternative broadband services.

In August 2021, we announced our plan to pass 10 million total locations with fiber. As of June 30, 2025, we have passed approximately 8.5 million total locations with fiber. We prioritize our activities to locations that we believe will provide the highest investment returns. As we implement our fiber expansion plan, we expect our business mix will shift significantly, with a larger percentage of revenue coming from fiber.

Our strategy focuses on four strategic priorities: fiber deployment, fiber penetration, improving the customer experience, and operational efficiency. We accomplished the following objectives in the second quarter of 2025:

We added approximately 334,000 fiber passings. As of June 30, 2025, we had approximately 8.5 million total locations passed with fiber.

We added 126,000 fiber broadband customer net additions.

We achieved over $600 million of cumulative run-rate cost savings as a result of our operational efficiency initiatives.

On September 4, 2024 we entered into the Merger Agreement with Verizon, pursuant to which, subject to certain terms and conditions therein, Verizon will acquire Frontier for $38.50 per share in cash, representing a premium of 43.7% to Frontier’s 90-Day volume-weighted average share price (VWAP) on September 3, 2024, the last full trading day prior to published market speculation regarding a potential sale of Frontier. Subject to receipt of certain required regulatory approvals and other customary conditions specified in the Merger Agreement, we currently expect the Merger to close by the first quarter of 2026. See Note 2 - ‘‘Merger Agreement’’ to the Consolidated Financial Statements included in Part I of this Quarterly Report for more detail.

Our fiber build plans include significant expenditures which could be adversely impacted by supply chain delays, actual or perceived inflation, trade tariffs and disputes, tight labor markets, increased fuel and electricity costs, increased cost of borrowing, and other risks. In addition to higher costs, the availability of building materials and other supply chain risks, including any effects of announced tariffs and changes in U.S. trade policy, could negatively impact our ability to achieve the fiber build plans we are executing against.

Current uncertainties about increases in tariffs of imported products from certain countries may have an adverse effect on our Company. The U.S. government has recently imposed tariffs on most U.S. trading partners and raised U.S. tariff rates. The ultimate impact of any tariffs will depend on various factors, including how long such tariffs remain in place, the ultimate levels of such tariffs and how other countries respond to the U.S. tariffs. While we are evaluating the potential impacts of these proposed tariffs, as well as our ability to mitigate their related impacts, this may increase our costs to build and make customer connections and repairs.

36

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

We continue to closely monitor and evaluate the impact these and other factors may have on our business, including demand for our products and services, our ability to execute on our strategic priorities and our financial condition and results of operations.

Financial Overview – Operating Income

We reported operating income of $44 million and $91 million for the three months ended June 30, 2025 and 2024, respectively, a decrease of $47 million.

We reported operating income of $120 million and $181 million for the six months ended June 30, 2025 and 2024, respectively, a decrease of $61 million.

Operating income decreased primarily due to increased depreciation expense associated with the continued investment in our fiber network. Growth in fiber data and internet service revenue more than offset decreases in revenue from voice and video services, resulting in $59 million and $108 million overall revenue growth during the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024.

Presentation of Results of Operations

The sections below include tables that present customer counts, average monthly consumer revenue per customer (“ARPC”), average monthly revenue per unit (“ARPU”), and consumer customer churn. We define churn as the number of consumer customer deactivations during the month divided by the number of consumer customers at the beginning of the month and utilize the average of each monthly churn in the period. Management believes that consumer customer counts, ARPC, ARPU, and consumer customer churn are important factors in evaluating our consumer customer trends. Among the key services we provide to consumer customers are voice service, data service and video service. We continue to explore the potential to provide additional services to our customer base, with the objective of meeting our customers’ communications needs.

The following section should be read in conjunction with the unaudited interim consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2024. The following charts present key customer metrics, disaggregation of revenue, and the results of operations of the consolidated company.

(a)Results of Operations

Unless otherwise indicated, the discussion of the customer metrics and components of operating income for the table that follows relates only to the financial results for the three and six months ended June 30, 2025, as compared to the financial results for the three and six months ended June 30, 2024.

Fiber Broadband Customers

Our investment strategy is focused on expanding our fiber network. In conjunction with this strategy, we are also working to improve our product positioning in both existing and new fiber markets.

For the three and six months ended June 30, 2025, we added approximately 120,000 and 223,000 consumer fiber broadband customers, compared to 90,000 and 175,000 net additions for the three and six months ended June 30, 2024, respectively. Customers who migrated from our copper base constituted a minor portion of these consumer fiber broadband customer net additions for the three and six months ended June 30, 2025.

For the three and six months ended June 30, 2025, we added approximately 6,000 and 10,000 business and wholesale fiber broadband customers compared to approximately 2,000 and 5,000 net additions for the three and six months ended June 30, 2024, respectively.

Our focus on expanding and improving our fiber network has contributed to improved customer retention. Our average monthly consumer fiber broadband churn was 1.29% and 1.25% for the three and six months ended June 30, 2025, compared to 1.40% and 1.32% for the three and six months ended June 30, 2024 respectively. This improvement was driven by increased focus on key customer touchpoints such as installation and first bill as well as inflation-related pricing actions and promotional pricing expiration.

o The average monthly consumer fiber broadband revenue per customer (“consumer ARPU”) increased $3.22, or 5%, to $68.54 and $3.01, or 5%, to $68.40 for the three and six months ended June 30, 2025, respectively, compared to the prior year periods.

o The increase in consumer ARPU for the three and six months ended June 30, 2025 was due to customer shifts to higher broadband speeds, customers rolling off promotional pricing, and inflation-related price increases, all partially offset by increased retention activity and autopay take rates.

Copper Broadband Customers

For the three and six months ended June 30, 2025, we lost approximately 45,000 and 86,000 consumer copper broadband customers compared to a loss of approximately 50,000 and 101,000 for the three and six months ended June 30, 2024, respectively.

For the three and six months ended June 30, 2025, we lost approximately 7,000 and 14,000 business and wholesale copper broadband customers, compared to a loss of approximately 6,000 and 12,000 in the three and six months ended June 30, 2024, respectively.

Our average monthly consumer copper broadband churn was 2.26% and 2.16% for the three and six months ended June 30, 2025, compared to 2.02% and 1.98% for the three and six months ended June 30, 2024, respectively. The increase in consumer copper broadband churn was driven primarily by the impact of inflationary price increases.

Consumer Customers

Consumer customers increased 4% as of June 30, 2025, as compared to the prior year period.

Consumer customer gains were driven by net additions of fiber broadband customers, partially offset by reductions in our copper broadband and stand-alone voice customers. Customer preferences as well as our fiber investment initiatives resulted in an increase in the number of our consumer broadband customers and a migration of our customer base to fiber.

We gained approximately 51,000 and 90,000 consumer customers for the three and six months ended June 30, 2025, compared to a gain of approximately 14,000 and 25,000 consumer customers for the three and six months ended June 30, 2024, respectively, driven by growth in fiber broadband customers, partially offset by losses in copper broadband, voice and video customers.

(Unaudited)

For the three and six months ended June 30, 2025, we experienced a net gain of consumer broadband customers of approximately 75,000 and 137,000 as compared to a net gain of approximately 40,000 and 74,000 for the three and six months ended June 30, 2024, respectively.

The average monthly consumer revenue per customer (“consumer ARPC”) increased $0.86, or 1%, to $84.43 and $0.75, or 1%, to $84.44 for the three and six months ended June 30, 2025, respectively, compared to the prior year periods. The increase for the three and six month periods was driven primarily by growth in fiber data and value-added services along with price increases, partially offset by declines in voice and video services.

(1)Includes lease revenue of $13 million and $26 million for the three and six months ended June 30, 2025 and $14 million and $27 million for the three and six months ending June 30, 2024, respectively.

Our revenue streams are primarily a result of recurring data, voice, and video services delivered over our network. Revenues are considered fiber or copper based on the “last-mile” technology used to connect the customer location. With our investment strategy to expand and improve our fiber network and the corresponding fiber focus of our sales and marketing efforts, we are experiencing growth in fiber revenue and a decline in copper revenue. We expect this trend to continue and accelerate due to strong fiber demand and the migration of customers from copper to fiber as we expand our fiber network.

(1)Includes lease revenue of $13 million and $26 million for the three and six months ended June 30, 2025 and $14 million and $27 million for the three and six months ending June 30, 2024, respectively.

We conduct business with a range of consumer, business and wholesale customers and we generate both recurring and non-recurring revenues. Recurring revenues are primarily billed at fixed recurring rates, with some services billed based on usage. Revenue recognition is not dependent upon significant judgments by management.

Consumer

For the three and six months ended June 30, 2025, compared to the three and six months ended June 30, 2024:

Consumer revenues were up 5% and 4% for the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024. The revenue growth was the result of growth in fiber data and value-added service revenues along with inflationary price increases, offset by declines in voice, video, and copper broadband.

o Consumer fiber broadband revenues increased 26% for both the three and six months ended June 30, 2025, as compared to the three and six months ended June 30, 2024.

o This improvement is a result of higher consumer fiber broadband ARPU as well as increased consumer fiber broadband net customer additions due to our expanded fiber footprint and continued focus on product positioning in both new and existing markets.

Consumer copper broadband revenues declined approximately 17% and 18% for the three and six months ended June 30, 2025 as compared to the prior year periods. As our copper footprint transitions to fiber, we expect fewer copper sales opportunities and will proactively migrate certain existing broadband customers from copper to fiber, both of which will reduce our copper customer base and revenues.

Business and Wholesale

For both the three and six months ended June 30, 2025, our business and wholesale revenues were up 3%, as compared to the prior year periods. This increase was driven by increases in data and internet services, partially offset by decreases in voice services revenue, predominantly in business. The increase in data and internet services was due to unit price increases in network access services and the continued growth of our fiber broadband customer base with a shift towards higher broadband speeds.

The table below presents our revenue by product and service type for the periods indicated:

We categorize our products, services, and other revenues into the following five categories:

Data and Internet Services

We provide data and Internet services to our consumer, business, and wholesale customers. Data and Internet services consist of fiber broadband services, copper broadband services, and network access revenues (data transmission services and dedicated high-capacity circuits including data services to wireless providers commonly called wireless backhaul). Network access services are provided primarily to our business and wholesale customers, while fiber and copper broadband are provided to all customer segments.

‎

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

Our fiber expansion strategy has positively impacted data and Internet services. Fiber network expansion provides faster, symmetrical broadband speeds and provides both customer and revenue growth opportunities for fiber broadband and network access products like ethernet. We believe this initiative will create opportunities for us to provide more fiber-based services to our customers.

| ($ in millions) | For the three months ended |  | For the six months ended |
| Data and Internet services revenue, June 30, 2024 | $ | 983 |  | $ | 1,930 |
| Change in fiber broadband revenue |  | 109 |  |  | 209 |
| Change in copper broadband revenue |  | (26) |  |  | (52) |
| Change in other data and internet services |  | 19 |  |  | 47 |
| Data and Internet services revenue, June 30, 2025 | $ | 1,085 |  | $ | 2,134 |

Data and internet services revenue increased $102 million, or 10%, to $1,085 million and $204 million, or 11%, to $2,134 million, for the three and six months ended June 30, 2025, respectively, as compared to the prior year periods. The increase was driven by growth in fiber broadband and network access revenues, partly offset by declines in copper broadband revenue.

Voice services

We provide voice services consisting of traditional local and long-distance service and voice over Internet protocol (VoIP) service provided over our fiber and copper broadband networks. Voice services also include enhanced features such as call waiting, caller identification, and voice messaging services.

Voice services revenue declined $30 million, or 10%, to $282 million and $61 million, or 10%, to $572 million, for the three and six months ended June 30, 2025, respectively, as compared to the prior year periods. The decline was primarily due to net losses in business and consumer customers in addition to fewer customers bundling voice services with broadband as compared to the prior year periods, all partially offset by higher voice services ARPU.

Video services

Video services include revenues generated from traditional television (TV) services provided directly to consumer customers as well as satellite TV services provided through various satellite providers. Video services also include pay-per-view revenues, video on demand, equipment rentals, and video advertising. We have made the strategic decision to limit new subscriber sales of traditional TV services, focusing on our broadband products and OTT video options. We are partnering with OTT video providers and expect this to grow as OTT options are offered with our broadband products.

Video services revenue declined $20 million, or 23%, to $68 million and $40 million, or 22%, to $142 million, for the three and six months ended June 30, 2025, respectively, as compared to the prior year periods. The decline was primarily driven by traditional video customer losses, partially offset by price increases as compared to the prior year periods.

Other

Other customer revenue includes non-recurring equipment sales, network facility rental income, ancillary customer fees, directory listing services and switched access revenue. Switched access revenue includes revenue derived from allowing other carriers to use our network to originate and/or terminate their local and long-distance voice traffic. These switched access services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies.

44

PART I. FINANCIAL INFORMATION (Continued)

Other customer services revenue increased $4 million, or 5%, to $87 million and $2 million, or 1%, to $169 million, for the three and six months ended June 30, 2025, as compared to the prior year periods, driven by higher customer contribution to construction, partially offset by decreases in switched network access revenue and CPE revenue.

Subsidy and other revenue

Subsidy and other revenue was $17 million and $33 million for the three and six months ended June 30, 2025, respectively, as compared to $14 million and $30 million for the three and six months ended June 30, 2024, re spectively.

OPERATING EXPENSES

The table below presents our operating expenses for the periods indicated:

| Total operating expenses | $ | 2,930 |  | $ | 2,761 |  | $ | 169 |  | 6 | % |

Cost of service

Cost of service expenses include access charges and other third-party costs directly attributable to connecting customer locations to our network, and video content costs. Such access charges and other third-party costs exclude depreciation and amortization, and employee related expenses.

Cost of service increased $16 million and $15 million, for the three and six months ended June 30, 2025, respectively, as compared to the prior year periods. The increases in cost of service expense were driven by outside service rate increases resulting from higher inflation and storm-related cost. These increases were partially offset by video content costs as a result of declines in video customers and non-renewal of certain content agreements.

Selling, General, and Administrative

Selling, general, and administrative expenses (“SG&A expenses”) include the salaries, wages and related benefits and costs of corporate and sales personnel, travel, insurance, non-network related rent, advertising, and other administrative expenses.

45

PART I. FINANCIAL INFORMATION (Continued)

### FRONTIER COMMUNICATIONS PARENT, INC. AND SUBSIDIARIES

(Unaudited)

SG&A expenses increased by $41 million and $46 million, for the three and six months ended June 30, 2025, respectively, as compared to the prior year periods. These increases were primarily due to increases in third-party commissions and other fees, primarily due to legal disputes and litigation settlements, partially offset by lower compensation and benefit costs and a settled dispute with the Chief Executive Officer of Frontier’s predecessor company in the prior year.

Depreciation and Amortization

For the three and six months ended June 30, 2025 depreciation and amortization expenses increased $59 million and $116 million, respectively, as compared to the prior year periods. The increased depreciation and amortization expense was driven by higher depreciation expense as a result of higher property, plant and equipment in service.

Restructuring costs and other charges

Restructuring costs and other charges consist of consulting and advisory fees, workforce reductions, transformation initiatives, and other restructuring expenses.

For the three and six months ended June 30, 2025, restructuring costs and other charges decreased $10 million and $8 million, respectively, as compared to the three and six months ended June 30, 2024, primarily due to lower severance and employee costs, pension/OPEB special termination benefit enhancement costs related to a voluntary severance program, and consulting and legal costs due to the Verizon merger and other restructuring activities.

Pension and Other post-employment benefits (“OPEB”) costs

We allocate certain pension/OPEB expense to cost of service and SG&A expenses.

Total pension and OPEB service costs, excluding pension/OPEB special termination benefit enhancement were as follows:

Investment and other income, net

Investment and other income, net increased by $38 million for the three months ended June 30, 2025, compared to the three months ended June 30, 2024. This increase was primarily attributable to a $72 million pension remeasurement loss during the three months ended June 30, 2024, partially offset by post-retirement remeasurement gain of $18 million, in the prior-year quarter and a $13 million reduction in interest and dividend income, which reflected lower average cash and short-term investment balances during the current quarter.

Investment and other income, net decreased by $25 million for the six months ended June 30, 2025, compared to the six months ended June 30, 2024. This decrease was primarily attributable to a $35 million reduction in post-retirement remeasurement gain, a $22 million reduction in interest and dividend income, and a $9 million reduction in pension benefit, partially offset by a $42 million increase in pension remeasurement gain.

Interest expense

For the three and six months ended June 30, 2025, interest expense increased $2 million and $1 million, respectively, as compared to the corresponding periods in 2024. The increase in interest expense was primarily driven by a higher debt balance.

Income tax expense

During the three and six months ended June 30, 2025, we recorded an income tax benefit of $16 million and $27 million, on pre-tax loss of $139 million and $214 million, respectively. During the three and six months ended June 30, 2024, we recorded an income tax expense of $9 million and $7 million on pre-tax loss of $132 million and $129 million, respectively.

Our effective tax rates for the three and six months ended June 30, 2025, was 11.6% and 12.8% and for the three and six months ended June 30, 2024 was 6.7% and 5.3%, respectively.

(b) Liquidity and Capital Resources

As of June 30, 2025, we had liquidity of approximately $2,340 million, comprised of $412 million of cash and cash equivalents, the available capacity on our delayed draw term loan facility of $1,170 million and available capacity on our undrawn revolving credit facility of $758 million.

On December 31, 2024, our subsidiaries Frontier Tampa Bay FL Fiber 1 LLC (“Borrower”) and Frontier SPE FL Guarantor LLC (“Guarantor”) entered into a credit agreement (the “Warehouse Credit Agreement”) with certain lenders that established and governs certain credit facilities (the “Warehouse Facilities”) including (i) a delayed draw term loan facility (the “DDTL Facility”) of $1.5 billion, less commitments reserved for letters of credit, and (ii) an incremental term loan facility under which the subsidiary borrower has the right to increase the commitments under the DDTL Facility by up to $750 million.

In connection with the establishment of the DDTL Facility, Frontier Issuer LLC canceled its agreement relating to the potential issuance of a $500 million Secured Fiber Network Revenue Variable Funding Notes, Series 2023-2, Class A-1 facility.

Analysis of Cash Flows

As of June 30, 2025, we had cash and cash equivalents aggregating $412 million. For the six months ended June 30, 2025, we used cash flow from operations, cash on hand, and cash from borrowings principally to fund our cash investing and financing activities, which were primarily capital expenditures.

As June 30, 2025, we had a working capital deficit of $1,845 million compared to a working capital deficit of $1,029 million at December 31, 2024. The primary drivers for the increase to the working capital deficit at June 30, 2025 were a decrease of $338 million in cash and cash equivalents, an increase in other current liabilities of $411 million, an increase in accounts payable and accrued liabilities of $163 million, and an increase of $9 million in accrued interest, partially offset by an increase in accounts receivable of $51 million and an increase in income taxes and other current assets of $37 million, as compared to the period ended December 31, 2024.

Cash Flows provided from Operating Activities

Cash flows provided from operating activities increased $287 million to $996 million for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The overall increase in operating cash flows was primarily the result of changes in depreciation and amortization and accounts payable and other liabilities offset by a decrease in profit.

We paid $2 million in net cash taxes during the six months ended June 30, 2025, compared to $9 million in tax refunds received during the six months ended June 30, 2024.

Cash Flows used by Investing Activities

Cash flows used by investing activities were $1,597 million for the six months ended June 30, 2025, compared to cash flows used by investing activities of $207 million for the prior year period. The decrease was driven by $310 million in higher capital expenditures in the current year period and the non-recurrence of $1,075 million in sales of short-term investments in the prior year period as compared to the current year period.

Capital Expenditures

For the six months ended June 30, 2025 and 2024, our capital expenditures were $1,602 million and $1,292 million, respectively. The increase in capital expenditures is offset by the decrease in capital related vendor financing payments.

(Unaudited)

Cash Flows used by Financing Activities

Cash flows provided from financing activities increased $749 million to $254 million for the six months ended June 30, 2025 as compared to the corresponding period in 2024. The increase in financing activities was primarily driven by the increase in net proceeds from long-term debt borrowings and a decrease in vendor financing payments in 2025.

Capital Resources

Our primary anticipated uses of liquidity are to fund the costs of operations, working capital and capital expenditures and to fund interest payments on our long-term debt. Our primary sources of liquidity are cash flows from operations, cash on hand and borrowing capacity under our $1,500 million DDTL Facility and $925 million Revolving Facility (as reduced by $167 million of revolver Letters of Credit and as reduced by $200 million of DDTL Facility letters of credit). As of June 30, 2025, there was $1,170 million of undrawn capacity under our DDTL Facility.

We have negotiated payment terms with certain of our vendors, (referred to as vendor financing), which are excluded from capital expenditures and reported as financing activities. As of June 30, 2025 and December 31, 2024 we had $0 million and $16 million, respectively, of vendor financing liabilities included in “Other current liabilities” on our consolidated balance sheet. Capital expenditures for the six months ended June 30, 2025 were $1,602 million, and when including $16 million cash paid for vendor financing, capital investment was $1,618 million.

We have assessed our current and expected funding requirements and our current and expected sources of liquidity, and have determined, based on our forecasted financial results and financial condition as of June 30, 2025, that our operating cash flows and existing cash balances will be adequate to finance our working capital requirements, fund capital expenditures, make required debt interest and principal payments, pay taxes and make other payments over the next twelve months. A number of factors, including but not limited to, loss of customers, pricing pressure from increased competition, lower subsidy and switched access revenues, and the impact of economic conditions may negatively affect our cash generated from operations.

Credit Facilities and Term Loans

Revolving Facility

On May 22, 2024, Frontier Communications Holdings, LLC, a subsidiary of Frontier (“Frontier Holdings”), entered into an amendment (the “2024 Credit Agreement Amendment”) to its existing credit agreement that governs its senior secured credit facility with certain revolving credit lenders (the “Revolving Facility”) which, among other things, (i) increased the aggregate amount of certain additional obligations permitted to be outstanding, including first lien debt, and securitization and receivables facilities, and non-loan party debt, from $2,500 million to $5,500 million; provided that at least 40% of the net available cash from the first $1,915 million in securitization and receivables facilities received after May 22, 2024 (excluding net available cash received from drawings with respect to $500 million of commitments of Variable Funding Notes) is applied to prepay Frontier Holdings’ existing term loans and other applicable indebtedness, and 100% of the net available cash from securitization and receivables facilities in excess thereof (up to the cap of $5,500 million) shall be applied to prepay Frontier Holdings’ existing term loans and other applicable indebtedness; (ii) limited future securitizations and receivables facilities to assets located in Texas and/or Florida; and (iii) amended the financial maintenance covenant for the benefit of the Revolving Facility by, commencing with the period ending June 30, 2024, (a) including outstanding securitization and receivables facilities in the calculation of indebtedness and (b) increasing the maximum financial maintenance covenant leverage ratio thereunder to 5.25:1.00, with a step-down to 4.75:1.00 commencing with the period ending March 31, 2027, and continuing thereafter. The 2024 Credit Agreement Amendment became effective on July 1, 2024, when $402 million of net available cash from the securitization closing on such date was applied to prepay existing term loans.

On July 30, 2024, Frontier Holdings entered into a further amendment to its existing credit agreement that governs its Revolving Facility, pursuant to which $50 million of revolving credit commitments of a terminating lender were replaced by $75 million of commitments from a new lender, increasing overall capacity from $900 million to $925 million. The maturity date of the Revolving Facility will be the earliest of (a) April 30, 2028, (b) 91 days prior to the

49

maturity of the term loan facility, (c) unless such notes have been repaid and/or redeemed in full, the date that is 91 days prior to the stated maturity date of our 5.875% First Lien Notes due 2027, and (d) unless such notes have been repaid and/or redeemed in full, the date that is 91 days prior to the stated maturity date of our 5.000% First Lien Notes due 2028.

On March 18, 2025, Frontier Holdings entered into a further amendment to its existing credit agreement that governs its Revolving Facility which, among other things, (x) (i) lowers the margin over adjusted Term SOFR with respect to the Revolving Facility from 3.50% to 2.50% and (ii) lowers the margin over the alternative base rate with respect to the Revolving Facility from 2.50% to 1.50%, (y) revises the prepayment requirement with respect to the Term Facility to replace the $500 million prepayment exception for the funding of variable funding notes with a $500 million prepayment exception for funding pursuant to a qualified securitization facility and (z) provides for an additional prepayment exception with respect to the Term Facility for up to $135 million, subject to certain requirements and limitations.

Term Loan Facility

On January 14, 2025, Frontier Holdings entered into an amendment to its existing Term Loan Facility, which, among other things, (x) further lowered the margin over adjusted Term SOFR with respect to the Term Loan from 3.50% to 2.50% and (y) further lowered the margin over the alternative base rate with respect to the Term loan from 2.50% to 1.50%. On July 1, 2024, Frontier Holdings entered into an amendment to the Term Loan Facility which, among other things, extended the maturity date of $1.025 billion of the Term Loan to July 1, 2031 and eliminated the credit spread adjustment previously applicable to the Term Loan.

On March 18, 2025, Frontier Holdings entered into a further amendment to its existing credit agreement as described under “Revolving Facility” above.

Fiber Network Revenue Term Notes

On July 1, 2024, Frontier Issuer LLC (“Frontier Issuer”), the Company’s limited-purpose, bankruptcy remote, subsidiary completed the issuance of $750 million aggregate principal amount of secured fiber network revenue term notes consisting of $530 million 6.19% Series 2024-1, Class A-2 term notes, $73 million 7.02% Series 2024-1, Class B term notes and $147 million 11.16% Series 2024-1, Class C term notes, each with an anticipated repayment term of seven years (collectively, the “Fiber Term Notes”). The Fiber Term Notes have a weighted average yield of approximately 7.4%. The Fiber Term Notes are secured by certain of Frontier’s fiber assets and associated customer contracts in the North Texas Area, in addition to those in the Dallas Metropolitan Area contributed in the Series 2023-1 Notes offering.

Warehouse Facilities

On December 31, 2024 (the “Warehouse Effective Date”), Frontier Tampa Bay FL Fiber 1 LLC (the “Warehouse Borrower”) and Frontier SPE FL Guarantor LLC, as guarantor (the “Warehouse Guarantor”), each a subsidiary of the Company, entered into a credit agreement (the “Warehouse Credit Agreement”) with certain lenders that establishes and governs certain credit facilities (the “Warehouse Facilities”). The Warehouse Facilities include:

A delayed draw term loan facility (the “DDTL Facility”) of $1.5 billion, less commitments reserved for letters of credit (the “Maximum DDTL Amount”). The DDTL Facility is available from the Warehouse Effective Date until the earlier of the full draw of the Maximum DDTL Amount or the third anniversary of the Warehouse Effective Date (such earlier date, the “DDTL Commitment Expiration Date”). To draw amounts under the DDTL Facility, the Warehouse Borrower must comply with a total leverage ratio of no more than 6.75:1.00 and a debt service coverage ratio of at least 2.00:1.00. Additionally, no defaults or other specified conditions may be continuing, and all conditions precedent for each extension of credit must be satisfied. The Warehouse Borrower must repay all outstanding amounts under the DDTL Facility due on the fifth anniversary of the Warehouse Effective Date. The interest rate for the DDTL Facility is either, at the sole discretion of the Warehouse Borrower, for Base Rate Loans, (a) the highest of (i) the “U.S. Prime Lending Rate” published by the Wall Street Journal, (ii) the Federal Funds Effective Rate (as agreed to in good faith by the parties to the Warehouse Credit Agreement) plus 0.50%, and (iii) one-month Term SOFR plus 1.00% per annum, plus (b)

50

PART I. FINANCIAL INFORMATION (Continued)

(Unaudited)

0.75%, with step-ups from and after the third anniversary, or, for SOFR Loans, Term SOFR plus 1.75%, with step-ups from and after the third anniversary. Optional prepayments are allowed without fees or penalties, subject to notice requirements. A portion of the DDTL Facility, up to $200 million, is reserved as a letter of credit sublimit.

An incremental term loan facility (the “Incremental Term Loan”) under which the Warehouse Borrower has the right to increase the commitments under the DDTL Facility by up to $750 million after the DDTL Commitment Expiration Date. No lender is required to increase its commitment. The Warehouse Borrower must comply with all representations and warranties, and the terms of any Incremental Term Loan must be identical to those of the DDTL Facilities, including maturity, priority of liens, prepayment terms, and pricing.

In the event of default, an additional 2.00% per annum will be applied to overdue amounts. Fees include commitment fees on undrawn portions, letter of credit fees, and fronting fees. The Warehouse Facilities are secured by first-priority pledges of equity interests and security interests in substantially all owned tangible and intangible assets of the Warehouse Borrower and its guarantors, which consist of the Warehouse Borrower’s fiber network assets and associated customer contracts in certain neighborhoods in the Tampa, Florida area.

Debt Covenants and Borrowing Capacity

Credit Agreement

Our Amended and Restated Credit Agreement includes usual and customary negative covenants for loan agreements of this type, including covenants limiting us and our restricted subsidiaries’ (other than certain covenants therein which are limited to subsidiary guarantors) ability to, among other things, incur additional indebtedness, create liens on assets, make investments, loans or advances, engage in mergers, consolidations, sales of assets and acquisitions, pay dividends and distributions and make payments in respect of certain material subordinated indebtedness, in each case subject to customary exceptions for loan agreements of this type.

Our Amended and Restated Credit Agreement also contains a “financial covenant” which provides that, commencing with the period ending June 30, 2024, our financial maintenance covenant leverage ratio shall not exceed as of the last day of each fiscal quarter 5.25:1.00, with a step-down to 4.75:1.00 commencing with the period ending March 31, 2027, and continuing thereafter.

This financial covenant is only applicable for the benefit of the Revolving Lenders (as defined in the Amended and Restated Credit Agreement) thereunder and failure to comply with the financial covenant would not cause an Event of Default with respect to any loans pursuant to our term loan facility unless and until the Required Revolving Lenders (as defined in the Amended and Restated Credit Agreement) have declared all amounts outstanding under the revolving facility to be immediately due and payable and all outstanding commitments under the revolving facility to be immediately terminated.

First Lien Notes and Second Lien Notes

The indentures governing our First Lien Notes and Second Lien Notes also include usual and customary negative covenants for debt securities of this type, including covenants limiting us and our restricted subsidiaries’ (other than certain covenants therein which are limited to subsidiary guarantors) ability to, among other things, incur additional indebtedness, create liens on assets, make investments, loans or advances, engage in mergers, consolidations, sales of assets and acquisitions, pay dividends and distributions and make payments in respect of certain material subordinated indebtedness, in each case subject to customary exceptions for debt securities of this type.

The indentures governing the outstanding subsidiary debentures include covenants that limit such subsidiary’s ability to create liens and/or merge or consolidate with other companies. These covenants are subject to important exceptions and qualifications.

Fiber Term Notes

The indenture governing Frontier Issuer’s Fiber Term Notes includes covenants and restrictions customary for transactions of this type. These covenants and restrictions include the maintenance of a liquidity reserve account to be used to make required payments in respect of the Fiber Term Notes, provisions relating to prepayments, required indemnification payments in certain circumstances. The Fiber Term Notes are also subject to rapid amortization in the event of a failure to maintain a stated debt service coverage ratio. 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. The Fiber Term 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 Fiber Term 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.

The Fiber Term Notes are subject to covenants and restrictions customary for transactions of this type, including (i) that the Issuer maintains specified reserve accounts to be used to make required payments in respect of the Fiber Term Notes and pay certain reserved fixed costs of the fiber networks, (ii) provisions relating to optional and mandatory prepayments of the Fiber Term Notes and the related payment of specified amounts, including specified make-whole payments in the case of prepayments of the Fiber Term Notes under certain circumstances, (iii) certain indemnification payments in the event, among other things, the assets pledged as collateral for the Fiber Term Notes are in stated ways defective or ineffective, and (iv) covenants relating to recordkeeping, access to information and similar matters. In addition, the terms of the indenture governing the Fiber Term Notes provide that a larger portion of Frontier Issuer’s available funds will be used towards the repayment of the Fiber Term Notes during a cash sweep period, which period would result from, among other things, the failure to maintain a certain debt service coverage ratio or a certain minimum penetration rate in the markets that were securitized at closing. The Fiber Term Notes are also subject to customary rapid amortization events provided for in the Indenture, including events tied to failure to maintain stated debt service coverage ratios, the acceleration of the maturity of the Fiber Term Notes following the occurrence of an event of default and the failure to repay or refinance on the applicable Anticipated Repayment Date (“ARD”).

The customary events of default to which the Fiber Term Notes are subject include events relating to non-payment of required interest, principal or other amounts due on or with respect to the Fiber Term 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. In addition, the Indenture and the related management agreement contain various covenants that limit the ability of the Company’s securitized subsidiaries to engage in specified types of transactions, subject to certain exceptions, including, for example, to incur or guarantee additional indebtedness, sell certain assets, create or incur liens on certain assets to secure indebtedness or consolidate, merge, sell or otherwise dispose of all or substantially all of their assets.

As of June 30, 2025, we were in compliance with all of the covenants under our existing indentures and the Amended and Restated Credit Agreement.

Warehouse Facilities

The Warehouse Credit Agreement includes covenants and restrictions customary for transactions of this type. The DDTL Facility contains a financial covenant which provides that the subsidiary borrower must comply with a total leverage ratio of no more than 6.75:1.00 and a debt service coverage ratio of at least 2.00:1.00, in addition to other customary conditions.

Off-Balance Sheet Arrangements

We do not maintain any off-balance sheet arrangements, transactions, obligations or other relationships with unconsolidated entities that would be expected to have a material current or future effect upon our financial statements.

Future Contractual Obligations and Commitments

There have been no material changes outside the ordinary course of business to the information provided with respect to our contractual obligations, including indebtedness and purchase and lease obligations, as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024.

Future Commitments

See “Regulatory Developments” immediately below for information regarding Frontier’s known and potential future commitments related to our participation in the FCC’s CAF Phase II program, NTIA BEAD program, and RDOF Phase I auction.

Regulatory Developments

Connect America Fund (“CAF”)/ Rural Digital Opportunity Fund (“RDOF”): In 2015, Frontier accepted the FCC’s CAF Phase II offer, which provided $313 million in annual support through 2021 in return for the Company’s commitment to make broadband available to households within the CAF II areas in our existing 25 states. The Company was required to complete the CAF II deployment by December 31, 2021. Thereafter, USAC and the FCC have been reviewing carriers’ CAF II program completion data, and should USAC or the FCC determine that the Company did not satisfy certain applicable CAF Phase II requirements, Frontier could be required to return a portion of the funds previously received and may be subject to certain other fines, requirements and obligations.

On January 30, 2020, the FCC adopted an order establishing the RDOF competitive reverse auction to provide support to serve high-cost areas. Frontier was awarded approximately $371 million over ten years to build gigabit-capable broadband over a fiber-to-the-premises network to approximately 127,000 locations in eight states (California, Connecticut, Florida, Illinois, New York, Pennsylvania, Texas, and West Virginia). We began receiving RDOF funding in the second quarter of 2022 and we will be required to complete the buildout to the awarded locations meeting certain annual milestones starting in December 31, 2025 through December 31, 2028. To the extent that Frontier is unable to fulfill the RDOF requirements, meet the milestones or construct to all locations by the required deadlines, funding to us could be discontinued and Frontier could be required to return a portion of funds previously received and may be subject to certain fines, requirements and obligations. Fines and penalties could also be assessed to the extent Frontier were ever to decide to surrender RDOF locations previously awarded.

In November 2021, Congress passed the IIJA which provides $65 billion to fund broadband connectivity programs, including broadband deployment to unserved and underserved locations. The National Telecommunications and Information Administration (NTIA) is administering the principal last mile infrastructure funding program in the amount of $42.5 billion, the Broadband Equity, Access & Deployment Program (BEAD), and will distribute funding through direct grants to states, who will then award the funds based on competitive grant programs. The NTIA has allocated approximately $25.5 billion to states in Frontier’s footprint. We participated in each of Frontier’s state challenge programs and pre-application and application processes. We are continuing to actively pursue awards of these stimulus funds; however, any awards that we ultimately receive under the IIJA may require significant up-front capital expenditures or other costs.

On June 6, 2025, NTIA issued a BEAD Restructuring Policy Notice to modify and replace certain requirements outlined in the BEAD Notice of Funding Opportunity. The Policy Notice rescinded all preliminary and provision subgrantee award selections and requires states to run at least one Benefit of the Bargain application round, in which minimal BEAD program outlay is the principal selection criteria. NTIA prohibited states from awarding additional points for 100% fiber projects but permitted them to prioritize “priority broadband projects” as that term is defined in the Infrastructure Investment and Jobs Act. The NTIA’s changes did not reduce the amount of funding allocated to each state for broadband infrastructure but eliminated certain potentially costly obligations associated with accepting BEAD awards, including middle-class affordability and low-cost offer pricing standards, open access, and climate change requirements, among others. It is uncertain if these changes will limit or impact Frontier’s participation in the BEAD program or its success in securing BEAD awards. We are closely tracking developments in this area, and additional

revision to the program could have a material adverse effect on the BEAD program, any funding we receive and the costs of completing BEAD award projects.

Privacy: Our businesses are subject to federal and state laws and regulations that impose various restrictions and obligations related to privacy and the handling of customers’ personal information. Privacy-related legislation has been adopted in a number of states in which we operate. Certain state requirements give consumers increased rights including the right to know what personal information is being collected about them and obtain a copy of such information, opt-out of the sale of personal information or sharing of personal information for purposes of certain targeted advertising, and to request the correction or deletion of this information. Complying with such laws, as well as other legislative and regulatory action related to privacy, could result in increased costs of compliance, claims against the Company or investigations related to compliance, and increased uncertainty in the use and availability of certain consumer data.

Video Programming: Federal, state, and local governments extensively regulate the video services industry. Our linear video services are subject to, among other things: subscriber privacy regulations; requirements that we carry a local broadcast station or obtain consent to carry a local or distant broadcast station; rules for franchise renewals and transfers; the manner in which program packages are marketed to subscribers; and program access requirements.

We provide video programming in some of our markets including California, Connecticut, Florida, Indiana, and Texas pursuant to franchises, permits and similar authorizations issued by state and local franchising authorities. Most franchises require payment of a franchise fee as a requirement to the granting of authority.

Many franchises establish facilities and service requirements, as well as specific customer service standards and monetary penalties for non-compliance. We believe that we are meeting all material standards and requirements. Franchises are generally granted for fixed terms and must be periodically renewed.

Environmental Regulation: The local exchange carrier subsidiaries we operate are subject to federal, state, and local laws, and regulations governing the use, storage, disposal of, and exposure to hazardous materials, the release of pollutants into the environment and the remediation of contamination. As an owner and former owner of property, we are subject to environmental laws that could impose liability for the entire cost of cleanup at contaminated sites, including sites formerly owned by us or our predecessors, regardless of fault or the lawfulness of the activity that resulted in contamination. We believe that our operations are in substantial compliance with applicable environmental laws and regulations.

Critical Accounting Policies and Estimates

The preparation of our financial statements requires management to make estimates and assumptions. There are inherent uncertainties with respect to such estimates and assumptions; accordingly, it is possible that actual results could differ from those estimates and changes to estimates could occur in the near term. These critical accounting estimates have been reviewed with the Audit Committee of our Board of Directors.

There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2024.

value of a financial instrument as a result of fluctuations in interest rates and equity prices. We do not hold or issue derivative instruments, derivative commodity instruments or other financial instruments for trading purposes. As a result, we do not undertake any specific actions to cover our exposure to market risks, and we are not party to any market risk management agreements other than in the normal course of business. Our primary market risk exposures from interest rate risk and equity price risk are as follows:

## Interest Rate Exposure

Our exposure to market risk for changes in interest rates relates primarily to the interest-bearing portion of our pension investment portfolio and the related actuarial liability for pension obligations, as well as our floating rate indebtedness. As of June 30, 2025, 89% of our total debt had fixed interest rates. We had no interest rate swap agreements in effect at June 30, 2025. We believe that our currently outstanding obligation exposure to interest rate changes is minimal.

Our objectives in managing our interest rate risk are to limit the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, only the $1.0 billion term loan facility and the $330 million drawn on our $1.5 billion DDTL facility has a floating rate at June 30, 2025. The annual impact of a 100 basis points increase in the SOFR would result in approximately $13 million of additional interest expense, provided that the SOFR rate exceeds the SOFR floor. An adverse change in interest rates would increase the amount that we pay on our variable rate obligations and could result in fluctuations in the fair value of our fixed rate obligations. Based upon our overall interest rate exposure, a near-term change in interest rates would not materially affect our consolidated financial position, results of operations or cash flows.

At June 30, 2025, the fair value of our debt was estimated to be approximately $12.1 billion, based on quoted market prices, our overall weighted average borrowing rate was 6.801% and our overall weighted average maturity was approximately 4 years.

Our discount rate assumption for our pension benefit obligation is determined at least annually, or whenever required, with assistance from our actuaries. The discount rate is based on the pattern of expected future benefit payments and the prevailing rates available on long-term, high quality corporate bonds with durations approximate to that of our benefit obligation. As of December 31, 2024, the discount rate utilized in calculating our benefit plan obligation was 5.60%. As of June 30, 2025, the discount rate utilized in calculating our benefit plan obligation was 5.50%.

The discount rate assumption for our OPEB obligation is determined in a similar manner to the pension plan. As of December 31, 2024, our discount rate utilized in calculating our benefit plan obligation was 5.70%. As of June 30, 2025, the discount rate utilized in calculating our benefit plan obligation was 5.50%.

## Equity Price Exposure

Our exposure to market risks for changes in equity security prices as of June 30, 2025 is primarily limited to our pension plan assets. We have no other security investments of any significant amount.

The value of our pension plan assets increased $99 million from $2,328 million at December 31, 2024 to $2,427 million at June 30, 2025. This increase primarily resulted from changes in the market value of investments of $119 million, net of plan expenses, and contributions of $62 million, offset by benefit payments to participants of $82 million.
