REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Savings Plan Committee of the

FirstEnergy Corp. Savings Plan

Akron, Ohio

<u>Opinion on the Financial Statements</u>

We have audited the accompanying statements of net assets available for benefits of FirstEnergy Corp. Savings Plan (the "Plan") as of December 31, 2025 and 2024, the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

<u>Basis for Opinion</u>

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on the Plan's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting, but not for purposes of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant

estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

<u>Supplemental Information</u>

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2025 has been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

We have served as the Plan's auditor since 2003.

**Notes to Financial Statements**

**____________________________________________________________________________________________________________________________________________________**

**1. Description of the Plan**

The following brief description of the FirstEnergy Corp. Savings Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan documents for more complete information.

**General**

The Plan is a defined contribution plan and was established to provide a systematic savings program for eligible employees and to supplement such savings with employer contributions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA), and the Internal Revenue Code of 1986, as amended (IRC).

**Administration**

FirstEnergy Corp. (FE) is the sponsor of the Plan. The FE Savings Plan Committee is the administrator of the Plan and has responsibility for the day-to-day administration of the Plan. Record keeping with respect to individual participant accounts is maintained by Fidelity Workplace Services, LLC. Plan assets are held in trust under an arrangement with Fidelity Management Trust Company.

**Participation**

Generally, all full-time and part-time employees of FE's subsidiaries and participating employees not represented by a collective bargaining union are eligible to participate in the Plan. Full-time and part-time employees represented by a labor union may participate to the extent permitted by their respective collective bargaining agreement.

Unless otherwise provided in a collective bargaining agreement, new employees are automatically enrolled in the Plan with a deemed election to contribute, on a pre-tax basis, 6% of eligible earnings for each payroll period with automatic increases of 1% each April until the employee contribution rate reaches 10%. Automatic enrollment and annual increases can be changed by Plan participants at any time. Plan participants who do not make an affirmative election as to the investment of his or her contributions shall have his or her contributions invested in the age appropriate LifePath Portfolio Fund made available to all Plan participants. A LifePath Portfolio Fund is an investment alternative that provides a mixture of fixed income and equity investments that are matched to an individual's age and assumed retirement date.

**Contributions**

Subject to IRC limitations, the Plan allows each participant to contribute 1% to 75% (unless otherwise provided by a collective bargaining agreement) of their eligible earnings to the Plan through payroll deductions. Participant contributions may be made as before-tax, after-tax or Roth 401(k) contributions (unless otherwise provided by a collective bargaining agreement). During any calendar year in which a participant attains age 50 or older, he or she may elect to make additional pre-tax contributions and/or Roth contributions, called "catch-up" contributions.

Unless otherwise provided in a collective bargaining agreement, FE makes a matching contribution of 50% on the first 6% of eligible compensation contributed by an employee. All employer matching contributions are provided as shares in FE common stock, except for certain IBEW Local 777 participants whose matching contributions are made in cash. Catch-up contributions are not eligible for matching contributions. The number of shares of FE common stock contributed to each participant is based on the market price of FE common stock as of the end of each pay period. Plan participants may diversify matching contributions held in FE common stock at any time, subject to certain limitations.

**Participant Accounts**

Individual accounts are maintained for each Plan participant. Each participant's account is credited with the participant's contributions, employer matching contributions and earnings. The value of an account is updated each business day and participants are vested in the entire value of their account at all times.

**Investments**

------

**FirstEnergy Corp. Savings Plan**

**Notes to Financial Statements**

**____________________________________________________________________________________________________________________________________________________**

Participants direct the investment of their contributions and account balances into various investment options including nine LifePath Funds that include a diversified mix of asset classes based on expected retirement dates (commonly referred to as target date funds), fifteen Plan investment options with different objectives covering a range of asset classes and risk levels and a self-managed brokerage account that offers participants the ability to invest in any security listed on the New York Stock Exchange (NYSE), the NYSE MKT LLC (formerly known as the American Stock Exchange or NYSE Amex LLC) or the NASDAQ and a wide range of mutual funds.

The Plan's investment options include a fund of shares of FE common stock, which together with a small portion of cash maintained for liquidity purposes, are recorded on a unit basis. FE's common shares are traded on the NYSE and participation units in the FE Common Stock Fund are valued at the NYSE closing price on the last business day of the plan year. The valuation per share of FE's common stock was $44.77 and $39.78 at December 31, 2025 and 2024, respectively. The valuation per unit of the FE Common Stock Fund was $54.50 and $48.46 at December 31, 2025 and 2024, respectively, due to cash maintained in the fund for liquidity purposes.

**Notes Receivable from Participants**

Participants may borrow up to 50% of their total account balance, excluding their Roth 401(k) balance, not exceeding $50,000, including loans outstanding and the highest unpaid loan balance over the previous 12 months. The interest rate for new loans is adjusted each quarter to the prime rate plus 1% based on the prime rate on approximately the 15th day of the last month of the preceding quarter. Effective April 1, 2019, the interest rate for new loans will be equal to the prime rate that is published by Reuters on the last day of the month before the start of the calendar quarter in which the loan is approved, plus 1%. The range of interest rates on outstanding loan balances during the year ended December 31, 2025 was 4.25% to 9.75%. Participants may have up to two loans outstanding at one time. The minimum loan amount is $1,000 and must be repaid within 6 to 60 months. If the loan is for the purchase of a principal residence, the loan repayment period can be extended up to 30 years. Principal repayments and payments of interest are credited to the participant's account when made, generally through payroll deduction. If a participant fails to make regularly scheduled payments, the participant has 90 days from the first missed scheduled repayment to pay the full amount in arrears. If full repayment of the amount in arrears doesn't occur, the outstanding balance of the loan will be defaulted and become a taxable distribution to the participant. If an eligible participant elects to take full distribution of their account balance and a loan balance remains, the entire loan balance remaining will be taxable.

**Payment of Benefits**

Upon termination of service due to disability, retirement or any other reason, a participant may elect to receive the full value or a portion of his or her account, defer payment to a later date (generally, not beyond April 1<sup>st</sup> of the year following the year the participant reaches age 73) or receive installment payments. In the event of a participant's death, the participant's spouse may elect to withdraw all or a portion of the former participant's account or keep the funds in the Plan in accordance with provisions of the Plan; all other beneficiaries must withdraw or rollover the former participant's account within 180 days. Retired and separated participants with vested balances of $1,000 or less are required to take full distribution of their account.

**Subsequent Events**

Management evaluated subsequent events for the Plan through June 26, 2026, the date the financial statements were available to be issued.

**2. Summary of Significant Accounting Policies**

The accompanying financial statements have been prepared on the accrual basis of accounting. Benefits are recorded when paid. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect reported amounts and disclosures. Actual results may differ from these estimates.

The Plan's investments are stated at fair value. Fair value reflects the price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly

**Notes to Financial Statements**

**____________________________________________________________________________________________________________________________________________________**

transaction between willing market participants on the measurement date. See Note 5 for a discussion of fair value measurements. Contract value is the relevant measurement attribute for that portion of the net assets available for benefits of the Plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan.

Notes receivable from participants represent participant loans and are measured at their unpaid principal balance plus any accrued interest. Delinquent participant loans are reclassified as distributions based upon the terms of the Plan document. Repayments of principal and interest are recognized in the period in which payroll deductions are processed.

Investment income consists of interest and dividend income. The net change in the fair value of investments consists of realized and unrealized gains and losses on those investments. Dividend income is accrued on the ex-dividend date. Purchases and sales of securities are recorded on a trade-date basis. Realized gains and losses from security transactions are reported based on historical cost.

Expenses for the administration of the Plan are generally paid by the Plan.

**3. Recently Adopted Accounting Pronouncements**

There are no recent accounting pronouncements not yet adopted which are expected to have a material impact on the Plan.

**4. Plan Termination**

Although FE has not expressed any intent to do so, it reserves the right to discontinue or terminate the Plan at any time. If the Plan were terminated, in whole or in part, participants would be entitled to withdraw the full value of their accounts, to the extent allowed by law.

**5. Investments and Fair Value Measurements**

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the Statements of Net Assets Available for Benefits.

Authoritative accounting guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy gives the highest priority to Level 1 measurements and the lowest priority to Level 3 measurements.

------

**FirstEnergy Corp. Savings Plan**

**Notes to Financial Statements**

**____________________________________________________________________________________________________________________________________________________**

The three levels of the fair value hierarchy are as follows:

---

| | |
|:---|:---|
| Level 1 | – Quoted prices for identical instruments in active markets. |
| Level 2 | – Quoted prices for similar instruments in active markets; |
|  | – Quoted prices for identical or similar instruments in markets that are not active; and |
|  | – Model-derived valuations for which all significant inputs are observable market data. |
|  | Models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. |
| Level 3 | – Valuation inputs are unobservable and significant to the fair value measurement. |

---

The Plan did not hold any Level 3 investments as of December 31, 2025 or 2024, or during the year ended December 31, 2025.

There were no changes in valuation methodologies for assets measured at fair value during 2025.

The following tables set forth, by level within the fair value hierarchy, the fair value of the Plan's investments as of December 31, 2025 and 2024:

**6. Fully Benefit-Responsive Investment Contracts**

The Plan has an interest in synthetic guaranteed investment contracts (GICs) as part of the Capital Preservation Fund, which is managed by Pacific Investment Management Company (PIMCO).

In accordance with authoritative guidance for defined contribution plans, investment contracts are generally measured at contract value rather than fair value to the extent they are fully benefit-responsive. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Participants transact with their investment in the Capital Preservation Fund at contract value as determined by the insurers and banks. No valuation reserve in relation to the contract value was deemed necessary. The Statement of Changes in Net Assets Available for Benefits and the Statements of Net Assets Available for Benefits present the synthetic GICs on a contract value basis.

A synthetic investment contract includes a wrapper contract, which is an agreement for the wrap issuer, such as a bank or insurance company, to make payments to the Plan in certain circumstances. The wrapper contract typically includes certain conditions and limitations on the underlying assets owned by the Plan.

The synthetic investment contracts held by the Plan include wrapper contracts that provide a guarantee that the credit rate will not fall below 0%. Cash flow volatility (for example, timing of benefit payments), as well as asset underperformance, can be passed through to the Plan through adjustments to future contract crediting rates. Formulas are provided in each contract that adjusts renewal crediting rates to recognize the difference between the fair value and the book value of the underlying assets. Crediting rates are reviewed monthly for resetting.

Certain events limit the ability of the Plan to transact with the issuer at contract value. These events include closings (location, subsidiary, division), layoffs, Plan termination, bankruptcy or reorganization, corporate merger, early retirement incentive programs or similar events. The Plan Administrator does not believe any such events of the magnitude that would limit the Plan's ability to transact at contract value are probable. The GICs do not permit the issuers to terminate the contracts at an amount other than contract value.

**Notes to Financial Statements**

**____________________________________________________________________________________________________________________________________________________**

The following represents the disaggregation of contract value between types of investment contracts held by the Plan at December 31, 2025 and 2024:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Short-term investment fund | $7235881 | $10697898 |
| Synthetic GICs | 306527392 | 333040410 |
| &nbsp;&nbsp;&nbsp;Total Investments at contract value | $313763273 | $343738308 |

---

The synthetic GICs are presented on Schedule H, line 4i - Schedule of Assets (Held at End of Year) at fair value as a requirement of Form 5500. The fair value of the synthetic GICs represents the total fair value of the underlying assets plus the wrap value, which is calculated by using the discounted cash flows of the difference between the current wrap fee and the market indication wrap fee.

**7. Tax Considerations**

The Plan is exempt from federal, state and local income taxes. The Plan obtained its latest favorable determination letter on October 27, 2016, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the IRC. The Plan has been amended since receiving the determination letter. However, the Plan Administrator and the Plan's tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC.

The federal, state and local income tax treatments of distributions from the Plan depend upon when they are made and their form. The withdrawal of the principal amount of a participant's after-tax contribution is not, however, subject to tax. For tax years beginning after December 31, 1986, the Tax Reform Act of 1986 requires that an additional tax of 10% be applied to participant withdrawals from the Plan prior to death, disability, attainment of age 59-1/2 or under certain other limited circumstances. In the case of withdrawal by a participant employed by FE or its consolidated subsidiaries (FirstEnergy) prior to the attainment of age 59-1/2, the excess of the value of the withdrawal over the total amount of the participant's after-tax contributions, is taxable at ordinary income tax rates. The value of FE's common stock withdrawn is considered to be its fair value on the date it is withdrawn.

In the case of a distribution that qualifies as a lump-sum distribution upon a participant's termination of employment with FirstEnergy or after attaining the age of 59-1/2, only the excess of the value of the lump sum distribution over the amount of the participant's after-tax contributions to the Plan (less withdrawals) is taxable at ordinary income tax rates. In determining the value of the lump-sum distribution, the FE common stock distributed in-kind or in cash is measured at fair value on the date it is withdrawn.

The Plan is subject to audits by taxing jurisdictions. GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability if the Plan has taken an uncertain position that more than likely would not be sustained upon examination by taxing authorities. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2025 and 2024, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or disclosure in the financial statements.

**8. Party-In-Interest Transactions**

Certain Plan investments are shares of mutual funds managed by Fidelity Investments. Fidelity Management Trust Company, a related company, is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions.

PIMCO is the fund manager of the Capital Preservation Fund and invests in certain investments managed by PIMCO and, therefore, these transactions qualify as party-in-interest transactions.

Certain Plan investments are shares of FE common stock with sales and purchases of the stock commencing on an as-needed basis. The investments and transactions qualify as party-in-interest transactions.
