Item 1.01.

Entry into a Material Definitive Agreement.

The information set forth in the Introductory Note of this Current Report on Form 8-K is incorporated herein by reference into this Item 1.01.

Registration Rights Agreement

On the Closing Date, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the Sellers, who received Stock Consideration (as defined below) in the Transaction (each such Seller, a “Selling Stockholder”), pursuant to which the Sellers will have certain customary “piggy-back” and shelf registration rights relating to the shares of the Company’s common stock comprising the Stock Consideration received by such Sellers as a result of the Transaction.

Pursuant to the Registration Rights Agreement, the Company is required (subject to certain conditions and exceptions) to prepare and file with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form S-3 for the resale of the shares of the Company’s common stock comprising the Stock Consideration received by the Sellers as a result of the Transaction.

The shares of Company common stock received by the Selling Stockholders in the Transaction are subject to a lock-up period beginning on the Closing Date and ending on the date that is six (6) months after the Closing Date (July 30, 2026). During the lock-up period, the Selling Stockholders may not transfer their shares, subject to certain exceptions set forth in the Registration Rights Agreement.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the Registration Rights Agreement, a copy of which is attached hereto as Exhibit 4.1 and incorporated herein by reference.

Voting Agreement

On the Closing Date, in connection with the Selling Stockholders’ receipt of the Stock Consideration in the Transaction, the Selling Stockholders entered into a voting trust agreement with Wilmington Savings Fund Society, FSB, as trustee (the “Trustee”), to limit certain voting rights of the Selling Stockholders with respect to their common stock to an aggregate level below ten percent (10%) of the Company’s total outstanding common stock in order to address certain requirements under the Federal Energy Regulation Commission’s rules and regulations and related order approving the Transaction.

Lightning Notes

On the Closing Date, Lightning (an indirect, wholly-owned subsidiary of the Company as of such date) remained the issuer of $1,500 million aggregate principal amount of 7.250% Senior Secured Notes due 2032 (the “Lightning Notes”) issued pursuant to an indenture, dated August 16, 2024 (the “Lightning Indenture”), by and among Lightning, Lightning’s subsidiaries that are guarantors from time to time party thereto, and U.S. Bank Trust Company, National Association, in its capacities as trustee and collateral trustee.

The Lightning Notes accrue interest at a rate of 7.250% per annum, payable semi-annually on February 15 and August 15 of each year. The Lightning Notes mature on August 15, 2032. At any time prior to August 15, 2027, Lightning may redeem all or a part of the Lightning Notes, at a redemption price equal to 100% of the principal amount of the notes redeemed, plus accrued and unpaid interest to the redemption date, plus a premium.

August 15, 2029 and thereafter		100.0000	%

Subject to certain qualifications and exceptions, the Lightning Indenture, among other things, limits Lightning’s ability and the ability of Lightning’s restricted subsidiaries to incur or guarantee additional indebtedness; create or incur liens; make certain restricted payments; and consolidate, merge or transfer all or substantially all of Lightning’s and its subsidiaries’ assets on a consolidated basis.

The foregoing description of the Lightning Indenture and the Lightning Notes does not purport to be complete and is qualified in its entirety by reference to the Lightning Indenture and the Lightning Notes, a copy of which is attached hereto as Exhibit 4.2 and incorporated herein by reference.

On the Closing Date, Lightning (an indirect, wholly-owned subsidiary of the Company as of such date) remains party to a credit agreement (the “Lightning Credit Agreement”) with Morgan Stanley Senior Funding, Inc. as administrative agent and collateral agent and various lenders and issuing banks from time to time party thereto.

The maturity date of the Lightning Term Loan and the Lightning Revolving Facility is August 16, 2031, and August 16, 2029, respectively.
