**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Plan Participants and Plan Administrator of ITC Savings & Investment Plan

**Opinion on the Financial Statements**

We have audited the accompanying statements of net assets available for benefits of ITC Savings & Investment 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.

**Basis for Opinion**

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. 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.

**Report on Supplemental Schedule**

The supplemental 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 schedule is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental schedule reconcile 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 schedule. In forming our opinion on the supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in compliance 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, such schedule is fairly stated, in all material respects, in relation to the financial statements as a whole.

**1. DESCRIPTION OF THE PLAN**

The following description of the ITC Savings & Investment Plan (the "Plan") is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

**General**

The Plan is a defined contribution plan covering substantially all employees of ITC Holdings Corp. ("ITC Holdings," or together with its subsidiaries, "ITC") and select FortisUS Inc. employees. International Transmission Company, a wholly-owned subsidiary of ITC Holdings, is the plan sponsor. The ITC Retirement Benefits Board ("RBB") controls and manages the operation and administration of the Plan. Fidelity Management Trust Company (the "Trustee") serves as the trustee and Fidelity Workplace Services LLC is the recordkeeper of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA").

**Contributions**

Each year, participants may contribute up to 75% of their eligible compensation, as defined in the Plan, subject to certain Internal Revenue Code (the "IRC") limitations. Participants' contributions are withheld from the participants' eligible compensation on a pre-tax, after-tax, or Roth after-tax basis. ITC provides a matching contribution of 100% of the first 4% of eligible compensation and 50% of the next 4% of eligible compensation that a participant contributes to the Plan. Participants may also contribute amounts representing distributions from other qualified defined contribution plans.

**Participant Accounts**

Individual accounts are maintained for each Plan participant. Each participant's account is increased for any participant contribution, ITC's matching contributions, an allocation of the Plan's investment earnings, and revenue sharing. Additionally, each participant's account is charged with withdrawals, administrative fees, and an allocation of the Plan's investment losses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

**Investments**

Participants direct the investment of their contributions and ITC's contributions into various investment options offered by the Plan and may change investments and transfer amounts between funds daily. The Plan currently offers mutual funds, including target retirement date funds, a stable value fund, collective investment trust ("CIT") funds, and Fortis Inc. common stock as investment options for participants. Participants also have the option to invest, through a self-directed brokerage account, in a variety of investments including individual stocks, bonds, mutual funds, and other investments beyond those offered directly by the Plan.

**Vesting**

Participants are vested immediately in all amounts credited to their accounts.

**Notes Receivable from Participants**

Participants may borrow from their fund accounts at a minimum of $1,000 up to a maximum of $50,000 or 50% of their account balance during the prior twelve-month period, whichever is less. Participants may only have two loans outstanding at any given time. Once any loan is paid in full, participants have a 180-day waiting period between loans. The notes are secured by the balance in the participant's account and bear interest at rates determined by the plan administrator based on the prevailing interest rates charged by financial institutions for loans, which would be made under similar circumstances. The interest rate remains fixed throughout the duration of the note. Principal and interest are paid ratably through payroll deductions and participants can pay down additional principal via check or Automated Clearing House ("ACH") payments. Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Delinquent notes are recorded as distributions

------

based on the terms of the Plan document. Notes receivable from participants under the Plan mature during the period of 2026 through 2035 and carry interest rates ranging from 5.25% to 10.50%.

**Payment of Benefits** 

Upon death, disability, retirement, termination of service, or upon reaching age 59 ½, a participant or participant's beneficiary may generally elect to receive either a lump-sum amount equal to the value of the participant's account balance or substantially equal installment distributions over a period of time equal to the participant's account balance. In addition, a participant may apply to receive a hardship withdrawal, subject to penalty, or apply to withdraw funds in certain limited circumstances without penalty.

**2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Basis of Accounting**

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

**Use of Estimates**

The preparation of financial statements in accordance with GAAP requires management to use estimates and assumptions that impact the reported amounts of assets, liabilities, and changes therein and disclosure of contingent assets and liabilities. Actual results may differ from these estimates.

**Risks and Uncertainties**

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate risk, credit risk, overall market volatility, and impacts of global events such as a pandemic or international conflict. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and such changes could materially affect the value of the participants' account balances that are reported in the financial statements.

**Investment Valuation and Income Recognition**

Investments are reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Refer to Note 3 for the discussion on fair value measurements.

Purchases and sales of securities are recorded on a trade-date basis, interest income is recorded on the accrual basis, dividends are recorded on the ex-dividend date, and net appreciation (depreciation) includes the Plan's gains and losses on investments bought and sold as well as held during the year.

**Expenses**

Administrative expenses of $13.50 per participant are deducted from participant accounts with balances greater than $3,000 each calendar quarter. Participants also pay administrative fees for loans, distributions, and investment management services. Management fees and operating expenses charged to the Plan for investments are deducted from income earned on a daily basis and are not separately reflected. Consequently, investment management fees and operating expenses are reflected as a reduction of investment return for such investments.

The Plan has a revenue-sharing agreement whereby certain investment managers return a portion of the investment fees to the record keeper to offset the Plan's administrative expenses. Administrative expenses are directly billed to each participant; therefore, the revenue sharing is returned to plan participants.

**Payment of Benefits**

Benefit payments to participants are recorded upon distribution. As of December 31, 2025 and 2024, there were no amounts allocated to accounts of persons who have elected to withdraw from the Plan but have not yet been paid.

------

**Excess Contributions Payable**

Amounts payable to participants for contributions in excess of amounts allowed by the Internal Revenue Service are recorded as a liability with a corresponding reduction to contributions. The Plan is required to return contributions received during the Plan year in excess of the IRC limits. There were no excess contributions due to participants as of December 31, 2025 and 2024.

**Subsequent Events**

Management has evaluated the impact of events and transactions that occurred after December 31, 2025, up to June 24, 2026, the date these financial statements were issued, for potential recognition or disclosure in the financial statements. The financial statements include all necessary adjustments and disclosures resulting from these evaluations.

**3. FAIR VALUE MEASUREMENTS** 

Accounting Standards Codification ("ASC") 820, *Fair Value Measurements and Disclosures*, provides a framework for measuring fair value. Fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The measurement of fair value is based on a three-tier hierarchy, which prioritizes the inputs used in measuring fair value, except for certain investments measured using net asset value ("NAV") as a practical expedient for fair value. These tiers include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1, defined as observable inputs such as quoted prices in active markets for identical assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The following are descriptions of our investments as reported on the statements of net assets available for pension benefits as well as the valuation methods and assumptions we use to estimate their fair values:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mutual funds: The mutual funds consist primarily of publicly traded mutual funds recorded at fair value based on observable trades for identical securities quoted in an active market. Investments in mutual funds sponsored by a registered investment company are valued based on exchange listed prices and are classified as Level 1 of the fair value hierarchy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Self-directed brokerage accounts: The self-directed brokerage accounts contain investments in a variety of categories including publicly-traded mutual funds and common stock which are recorded at fair value based on observable trades for identical securities in an active market and classified as Level 1. As of December 31, 2024, a portion of the self-directed brokerage accounts' underlying investments were certificates of deposit or government bonds, which were measured based on observable inputs (other than quoted prices in active markets) and classified as Level 2.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fortis Inc. common stock: This investment is valued at the closing market price reported on the New York Stock Exchange and is comprised of shares of Fortis Inc. common stock as well as cash and cash equivalents to facilitate execution of daily transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stable value fund: The stable value fund is a CIT fund that invests primarily in fully benefit-responsive investments and is valued at the net asset value of the units of the fund. The net asset value is used as a practical expedient to estimate fair value. This practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different than the net asset value. As of December 31, 2025 and 2024, there were no unfunded commitments and this investment offered daily liquidity. If the Plan initiates a full redemption of the CIT, the issuer reserves the right to require 12 months' notification in order to ensure that securities liquidations will be carried out in an orderly business manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Collective investment trust funds: The CIT funds are valued at the net asset value of units owned, which is based on the fair value of the underlying equity securities held by the funds and is provided by the fund sponsors. The net asset value is used as a practical expedient to estimate fair value. This practical expedient

------

would not be used if it is determined to be probable that any of the funds will sell the investment for an amount different than the net asset value. The CIT funds offer daily liquidity and there are no unfunded commitments. If the Plan initiates a full redemption of the CIT funds, the investment advisor reserves the right to temporarily delay withdrawal from the trust in order to confirm that securities liquidations will be carried out in an orderly business manner.

The following tables set forth by level within the fair value hierarchy a summary of the Plan's investments measured at fair value on a recurring basis at December 31, 2025 and 2024:

**4. RELATED PARTY AND EXEMPT PARTY-IN-INTEREST TRANSACTIONS**

Certain Plan investments are shares of investment funds, including mutual funds such as target retirement date funds, a money market mutual fund, and common stock of Fortis Inc., the parent company of the plan sponsor. All of the Plan investments are managed by the Trustee and therefore these transactions qualify as exempt party-in-interest transactions. ITC did not incur any fees associated with adding Fortis Inc. common stock to the Plan during 2025. During 2024, ITC reimbursed Fortis Inc. for expenses incurred totaling $31,002 associated with adding Fortis Inc. common stock to the Plan.

Revenue sharing of $74,286 and administrative expenses paid by the Plan of $152,309 for the year ended December 31, 2025 were allocated by investment to participant accounts and included as an increase and reduction, respectively, to each fund. For the year ended December 31, 2024, revenue sharing and administrative expenses paid by the Plan were $80,131 and $126,542, respectively. The revenue sharing is treated as a reduction of expenses paid by the Plan and, therefore, it is netted within administrative expenses on the statement of changes in net assets available for benefits.

------

The Plan recorded dividend income from Fortis Inc. common stock of $14,523 and $2,843, during the years ended December 31, 2025 and 2024, respectively, which is included in dividends and interest income within the statement of changes in net assets available for benefits. In addition, the Plan held 9,909 shares of Fortis Inc. common stock with a cost basis of $445,449 and 8,916 shares of Fortis Inc. common stock with a cost basis of $391,233, as of the years ended December 31, 2025 and 2024, respectively.

**5. PLAN TERMINATION**

Although it has not expressed any intention to do so, ITC has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions set forth in ERISA.

**6. FEDERAL INCOME TAX STATUS**

The Plan adopted a prototype plan document sponsored by Fidelity on March 1, 2003. Fidelity received an opinion letter from the Internal Revenue Service ("IRS"), dated June 30, 2020, which states that the prototype document satisfies the applicable provisions of the Internal Revenue Code ("IRC"). The Plan itself has not received a determination letter from the IRS. However, the Plan's management believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income tax has been included in the Plan's financial statements.

GAAP requires Plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. As of December 31, 2025, the Plan had not taken any known uncertain tax positions.

The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years 2021 and earlier.
