On December 19, 2025, Perimeter Holdings, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company (“Perimeter Holdings”) entered into an amended and restated credit agreement for its five-year Revolving Credit Facility (the “Amended and Restated Revolving Credit Facility), whereby the total aggregate principal amount was increased from $100.0 million to $200.0 million. The Company incurred $2.2 million of deferred finance fees as a result of the Amended and Restated Revolving Credit Facility for the year ended December 31, 2025.

The Amended and Restated Revolving Credit Facility matures on December 19, 2030, subject to a springing maturity ninety-one days prior to the maturity date of the Senior Notes, as defined below. The Amended and Restated Revolving Credit Facility includes a $40.0 million swingline sub-facility and a $50.0 million letter of credit sub-facility. The Amended and Restated Revolving Credit Facility allows the Company to increase commitments under the Amended and Restated Revolving Credit Facility up to an aggregate amount not to exceed the greater of (i) $315.0 million (or, after the completion of the MMT acquisition, $360 million) and (ii) 100.00% of consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA") for the most recent four-quarter period (minus the aggregate outstanding principal amount of certain ratio debt permitted to be incurred thereunder).

Borrowings under the Amended and Restated Revolving Credit Facility bear interest at a rate equal to (i) an applicable margin, plus (ii) at Perimeter Holdings option, either (x) Secured Overnight Financing Rate for the applicable corresponding tenor (“Term SOFR”) as published by CME Group Benchmark Administration, subject to a Floor of 1.00% or (y) a base rate determined by reference to the highest of (a) the prime commercial lending rate published by the Wall Street Journal, (b) the federal funds rate plus 0.50%, (c) the one-month Term SOFR rate plus 1.00% and (d) 1.00%. The applicable margin is 2.75% in the case of Term SOFR-based loans and 1.75% in the case of base rate-based loans, with two step-ups of 0.25% each based upon the achievement of certain leverage ratios.

Solely to the extent that on the last day of the applicable fiscal year, the utilization of the Amended and Restated Revolving Credit Facility (excluding cash collateralized letters of credit and up to $15.0 million of undrawn letters of credit) exceeds 40% of the aggregate commitments, the Amended and Restated Revolving Credit Facility requires compliance on a quarterly basis with a maximum secured net leverage ratio of 7.00:1.00.

The Amended and Restated Revolving Credit Facility is fully and unconditionally guaranteed by the Company and each of Perimeter Holdings’ existing and future domestic wholly-owned material restricted subsidiaries, subject to customary exceptions, and is secured by a first priority lien, subject to certain permitted liens, on substantially all of Perimeter Holdings’ and each of the guarantors’ existing and future property and assets, subject to customary exceptions.

Deferred financing costs incurred in connection with securing the Amended and Restated Revolving Credit Facility are carried as a long-term asset and are amortized on a straight-line basis over the term of the Amended and Restated Revolving Credit Facility and included in interest expense in the accompanying consolidated statements of operations and comprehensive (loss) income.

The Senior Notes are general, secured, senior obligations of Perimeter Holdings; rank equally in right of payment with all existing and future senior indebtedness of Perimeter Holdings (including, without limitation, the Amended and Restated Revolving Credit Facility); and together with the Amended and Restated Revolving Credit Facility, are effectively senior to all existing and future indebtedness of Perimeter Holdings that is not secured by the collateral. The Senior Notes are fully and unconditionally guaranteed on a senior secured basis, jointly and severally, by all of Perimeter Holdings’ existing or future restricted subsidiaries (other than certain excluded subsidiaries) that guarantee the Amended and Restated Revolving Credit Facility. The Senior Notes contain certain covenants limiting the Company’s ability and the ability of the restricted subsidiaries (as defined in the indenture governing the Senior Notes) to, under certain circumstances, prepay subordinated indebtedness, pay distributions, redeem stock or make certain restricted investments; incur indebtedness; create liens on Perimeter Holdings assets to secure debt; restrict dividends, distributions or other payments; enter into transactions with affiliates; designate subsidiaries as unrestricted subsidiaries; sell or otherwise transfer or dispose of assets, including equity interests of restricted subsidiaries; effect a consolidation or merger; and change the Company’s line of business. As of December 31, 2025, and 2024, the Company was in compliance with financial covenants.

Deferred financing costs incurred in connection with securing the Senior Notes were capitalized and are amortized using the effective interest method over the term of the Senior Notes and included in interest expense in the accompanying consolidated statements of operations and comprehensive (loss) income. The unamortized portion of the deferred financing costs is included as a reduction to the carrying value of the Senior Notes which have been recorded as long-term debt, net on the consolidated balance sheets as of December 31, 2025, and 2024.

Upon completion of the Redomiciliation Transaction on November 20, 2024 the previously issued 10 million redeemable preferred shares of Perimeter Solutions, SA (the “Lux Preferred Shares”), nominal value $10.00 per share, valued at $100.0 million, automatically converted by operation of law on a one-for-one basis into shares of preferred stock of Perimeter Solutions, Inc. par value $0.0001 per share (the “Preferred Stock”), stated value $100.0 million. The Certificate of Incorporation authorizes the issuance of 20 million shares of Preferred Stock which are entitled to a preferred annual cumulative right to a dividend equal to 6.50% of its nominal value. The preferred dividend will be paid 40.00% in cash and 60.00% in kind each year within three business days following the Company's annual general meeting. Holders of the Preferred Stock have no voting rights (only protective rights).

The Company, under its Certificate of Incorporation, is mandatorily required to redeem the Preferred Stock at any time prior to the earliest of (i) six months following the latest maturity date of the above-mentioned Senior Notes, (ii) nine years after the date of issuance of the Preferred Stock or (iii) upon the occurrence of a change of control, as defined in the Company’s Certificate of Incorporation.

Due to the fact that the shares of Preferred Stock are mandatorily redeemable, the shares of Preferred Stock are classified as a liability on the accompanying consolidated balance sheets, and $7.3 million, $7.1 million and $6.8 million of dividends on these shares of Preferred Stock for the years ended December 31, 2025, 2024 and 2023, respectively, are classified as interest expense in the accompanying consolidated statements of operations and comprehensive (loss) income.
