Report of Independent Registered Public Accounting Firm

To the Participants and Savings Plan Committee of the

FirstEnergy Corp. Savings Plan

Akron, Ohio

We have audited the accompanying statements of net assets available for benefits of the FirstEnergy Corp. Savings Plan (the “Plan”) as of December 31, 2016 and 2015, and the related statement of changes in net assets available for benefits for the year ended December 31, 2016. The Plan’s management is responsible for the financial statements. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2016 and 2015, and the changes in net assets available for benefits for the year ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America.

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2016 and schedule of reportable transactions for the year ended December 31, 2016 have been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is presented for the purpose of additional analysis and is not a required part of the financial statements but includes information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. 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 in the accompanying schedules, 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 in the accompanying schedules is fairly stated in all material respects in relation to the financial statements taken as a whole.

1.	Description of the Plan

The following brief description of the FirstEnergy Corp. Savings Plan (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. (FirstEnergy) is the sponsor of the Plan. The FirstEnergy Savings Plan Committee is the administrator of the Plan and has responsibility for the day-to-day administration of the Plan. Plan assets are held in trust under an arrangement with State Street Bank & Trust Company (State Street). Record keeping with respect to individual participant accounts is maintained by Fidelity Investments (Fidelity).

Participation

Generally, all full-time and part-time employees of FirstEnergy and its subsidiaries 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.

New employees who do not make an affirmative election to make (or not make) pre-tax contributions to the Plan are deemed to have made an election to contribute 3% of eligible earnings for each payroll period increasing by 1% each April until the employee contribution rate reaches the amount that will be subject to matching contributions. Certain union participants are automatically enrolled at 2%, Utility Workers Union of America (UWUA) Local 180 is without escalation and International Brotherhood of Electrical Workers (IBEW) Local 777 has an increase of 1% per year up to 4%. A new employee who has not made an affirmative election as to the investment of his or her account shall have his or her account invested in the age appropriate LifePath Portfolio Fund made available to 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% (22% for participants represented by UWUA Local 180) 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 (UWUA Local 180 and IBEW Local 777 are not eligible to elect Roth 401(k) contributions). 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. In order to be eligible to make catch-up contributions, the participant must anticipate that his or her pre-tax contributions and/or Roth contributions to the Plan will reach the applicable annual IRC limit on that type of contribution.

FirstEnergy makes a matching contribution of 50% on the first 6% of eligible compensation contributed by an employee, except for IBEW Local 777 and UWUA Local 180 participants who receive a matching contribution of 80% and 60%, respectively, on the first 4% of eligible contributions. All employer matching contributions are invested in FirstEnergy common stock, except for certain IBEW Local 777 and UWUA Local 180 participants whose matching contributions are invested in cash. Catch-up contributions are not eligible for matching contributions. The number of shares of FirstEnergy common stock contributed to each participant is based on the market price of FirstEnergy common stock as of the end of each pay period. FirstEnergy matching contributions are non-cash contributions made by issuing shares of common stock. Plan participants may diversify matching contributions held in FirstEnergy 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 allocated Plan earnings. Participants are vested in the entire value of their account at all times.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements

____________________________________________________________________________________________________________________________________________________

Investments

Participants direct the investment of their contributions and account balances into various investment options including ten LifePath Funds that include a diversified mix of asset classes based on expected retirement dates, sixteen 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 FirstEnergy common stock, which together with a small portion of cash maintained for liquidity purposes, are recorded on a unit basis. FirstEnergy’s common shares are traded on the NYSE and participation units in the FirstEnergy Common Stock Fund are valued at the NYSE closing price on the last business day of the plan year. The valuation per share of FirstEnergy’s common stock was $30.97 and $31.73 at December 31, 2016 and 2015, respectively. The valuation per unit of the FirstEnergy Common Stock Fund was $37.86 and $38.71 at December 31, 2016 and 2015, 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. The range of interest rates on outstanding loan balances during the year ended December 31, 2016 was 4.25% to 10%. 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 interest are credited to the participant’s account when made, generally through payroll deduction.

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 (not beyond age 70-1/2) 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.

Subsequent Events

Management evaluates events and transactions occurring subsequent to the date of the financial statements that affect recognition or disclosure to the financial statements.


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 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 appreciation (depreciation) in the fair value of investments consists of realized gains (losses) and unrealized appreciation (depreciation) on those investments.

Notes to Financial Statements

____________________________________________________________________________________________________________________________________________________

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.	Recent Accounting Pronouncements

In May 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (ASU 2015-07). ASU 2015-07 removes the requirement to include investments in the fair value hierarchy disclosure for which fair value is measured using the net asset value per share as a practical expedient under Topic 820. The plan adopted ASU 2015-12 as of December 31, 2016. There was no impact to the plan financials.


4.	Plan Termination

Although FirstEnergy 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, 2016 or 2015 or during the year ended December 31, 2016.

There were no changes in valuation methodologies for assets measured at fair value during 2016.

The following tables set forth, by level within the fair value hierarchy, the fair value of the Plan’s investments as of December 31, 2016 and 2015:

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 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 GIC's 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 percent. 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.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements

____________________________________________________________________________________________________________________________________________________

The following represents the disaggregation of contract value between types of investment contracts held by the Plan at December 31, 2016 and 2015:



	2016		2015

Short-term investment fund	$	23,933,495	$	16,644,003
Synthetic GIC's	541,703,894		526,710,773
Total Investments at contract value	$	565,637,389	$	543,354,776

The synthetic GIC's are presented on Schedule H, line 4i - Schedule of Assets (Held at End of Year) at fair value as a requirement of the 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 (IRS) 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 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 FirstEnergy’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 FirstEnergy 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, 2016 and 2015, 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 State Street Global Advisors. State Street, 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 FirstEnergy 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.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements

____________________________________________________________________________________________________________________________________________________

Additionally, the Plan uses the services of other fund managers that are paid directly by the Plan.

All of the above transactions are exempt from the prohibited transaction rules of ERISA.


9.	Reconciliation of Financial Statements to Form 5500

The following is a reconciliation of net assets available for benefits, investment income and interest income on notes receivable per the financial statements to Form 5500 as of December 31, 2016 and 2015, and for the year ended December 31, 2016:
