Item 1.01. Entry Into a Material Definitive Agreement

Issuance of METC Senior Secured Notes

On January 14, 2026, Michigan Electric Transmission Company, LLC (“METC”), an indirect wholly-owned subsidiary of ITC Holdings Corp. (the “Company”), issued $125,000,000 aggregate principal amount of its 5.08% Series A Senior Secured Notes due 2036 (the “Series A METC Notes”) and $125,000,000 aggregate principal amount of its 5.71% Series B Senior Secured Notes due 2046 (the “Series B METC Notes” and together with the Series A METC Notes, the “METC Notes”) in a private placement in reliance on an exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”). The METC Notes were sold by METC to institutional accredited investors (as defined by Rule 501(a) of the Securities Act) pursuant to a Purchase Agreement dated January 14, 2026 (the “Purchase Agreement”). METC agreed to sell the METC Notes subject to the satisfaction of certain terms and conditions provided in the Purchase Agreement. METC will apply the net proceeds of the sale of the METC Notes to repay existing indebtedness under its Revolving Credit Agreement, dated as of April 14, 2023 (as amended by that Amendment No. 1 to Revolving Credit Agreement, dated as of December 16, 2024 and as further amended, modified, supplemented, restated and replaced from time to time), repay indebtedness under its intercompany loan agreement with ITC Holdings Corp., to partially fund capital expenditures, and for general corporate purposes.

The METC Notes were issued under METC’s first mortgage indenture (the “Mortgage Indenture”), dated as of December 10, 2003, between The Bank of New York Mellon Trust Company, N.A., as successor to JPMorgan Chase Bank, as trustee (the “Trustee”), as supplemented by the thirteenth supplemental indenture thereto, dated as of December 16, 2025, between METC and the Trustee (the “Thirteenth Supplemental Indenture” and, together with the Mortgage Indenture, the “METC Indenture”). The METC Notes are secured by a first mortgage lien on substantially all of METC’s real and tangible personal property equally with all other securities theretofore or thereafter issued under the Mortgage Indenture, with such exceptions as described in, and such releases as permitted by, the METC Indenture.

Interest on the Series A METC Notes is payable semi-annually on January 14 and July 14 of each year, commencing on July 14, 2026, at a fixed rate of 5.08% per annum. Interest on the Series B METC Notes is payable semi-annually on January 14 and July 14 of each year, commencing on July 14, 2026, at a fixed rate of 5.71% per annum. METC may redeem the METC Notes, in whole or in part, in an amount not less than $5,000,000 in aggregate principal amount in the case of a partial redemption, at any time or from time to time with not less than 10 days and not more than 60 days’ prior notice at a redemption price equal to the sum of (a) 100% of the principal amount of such METC Notes, (b) accrued and unpaid interest thereon to the redemption date and (c) a make-whole amount, if any, determined using a discount rate of treasuries plus 90 basis points. METC may also redeem the Series A METC Notes in whole on or after October 14, 2035 at a redemption price equal to the principal amount of the Series A METC Notes plus accrued and unpaid interest thereon to the redemption date. METC may also redeem the Series B METC Notes in whole on or after July 14, 2045 at a redemption price equal to the principal amount of the Series B METC Notes plus accrued and unpaid interest thereon to the redemption date. The principal amount of the Series A METC Notes is payable on January 14, 2036 and the principal amount of the Series B METC Notes is payable on January 14, 2046.

The METC Notes and the METC Indenture contain events of default customary for such a transaction, including, without limitation, failure to pay interest on any Security (as defined in the METC Indenture) for five days after becoming due; failure to pay principal on any Security when due; failure to comply with material covenants contained in the METC Indenture, subject to a 30-day cure period; failure to comply with other covenants contained in the METC Indenture and the other financing agreements relating to the offering of the METC Notes, subject to a 60-day cure period; material breaches of representations and warranties; defaults in respect of obligations relating to certain debt; certain unsatisfied judgments; and certain events relating to reorganization, bankruptcy and insolvency of METC. If an “Event of Default” (as defined in the METC Indenture) occurs, any holder of the Securities may accelerate its Securities (rather than all the Securities) pursuant to any payment Event of Default; the trustee or holders of 25% (in the case of a payment default) or a majority (in the case of any other default) of the outstanding principal amount of the Securities may accelerate all the Securities pursuant to any Event of Default; and all amounts are automatically accelerated pursuant to any reorganization, bankruptcy or insolvency Event of Default.
