Credit Agreement

On June 30, 2026 (the “Effective Date”), the Company entered into a credit agreement (the “Credit Agreement”) by and among the Company as borrower, the lenders from time to time party thereto (the “Lenders”) and Wells Fargo Bank, National Association, as administrative agent and collateral agent for the Lenders.

The Credit Agreement provides for a senior secured revolving credit facility in an aggregate principal amount of $200,000,000 (the “Revolving Credit Facility”; and any loans thereunder, the “Revolving Loans”), including a $10,000,000 sublimit for the issuance of letters of credit. In addition, the Company has the right at any time and from time to time to incur one or more additional revolving commitments and/or incremental term loans up to an unlimited amount, subject to certain customary conditions precedent and other requirements, including compliance with a specified leverage ratio. The Lenders are not obligated to provide any such additional commitments or loans. The proceeds of the Revolving Loans may be used for working capital and other general corporate purposes. As of the Effective Date, there are no outstanding loans under the Credit Agreement.

The maturity date of the Revolving Credit Facility is the fifth anniversary of the Effective Date, subject to a springing maturity that is 91 days prior to the earliest scheduled maturity date of any Inside Date Convertible Debt (as defined in the Credit Agreement, including the Company’s 0% Convertible Senior Notes due 2031) if the aggregate outstanding principal amount of such Inside Date Convertible Debt exceeds the greater of $270,000,000 and 75% of Consolidated EBITDA (as defined in the Credit Agreement) at such time, unless either (i) the Company’s liquidity (which includes amounts available under the Revolving Credit Facility and the consolidated unrestricted cash and cash equivalents of the Company and its restricted subsidiaries) at such time is greater than 125% of the aggregate outstanding principal amount of such Inside Date Convertible Debt or (ii) the Total Net Leverage Ratio (as defined in the Credit Agreement) does not exceed 2.50 to 1.00 for the then most recently completed four fiscal quarters.

Revolving Loans may be borrowed, repaid and reborrowed, until their maturity date under the Credit Agreement, and may be prepaid by the Company without premium or penalty (subject to customary breakage costs). The Revolving Loans bear interest, at the Company’s option, at a rate equal to either (i) term SOFR, plus an applicable margin ranging

from 1.75% to 2.50% per annum based on the Total Net Leverage Ratio, or (ii) a base rate equal to the highest of (w) 1.00%, (x) the federal funds rate plus 0.50%, (y) the prime rate and (z) term SOFR for an interest period of one month plus 1.00%, plus an applicable margin ranging from 0.75% to 1.50% per annum based on the Total Net Leverage Ratio. Undrawn commitments under the Revolving Credit Facility are subject to a commitment fee ranging from 0.25% to 0.40% per annum based on the Total Net Leverage Ratio on the average daily unused portion of such commitment that is available to the Company. The applicable margin for and certain other terms of any additional revolving commitments or incremental term loans will be determined prior to the incurrence of such commitments or loans.

The Credit Agreement contains customary representations, warranties, and affirmative and negative covenants. The negative covenants include restrictions on liens, investments, indebtedness, fundamental changes, restricted payments, transactions with affiliates, prepayments of subordinated debt and other matters, all subject to certain exceptions. In addition, the Credit Agreement contains financial covenants that require the Company to maintain (i) a maximum Total Net Leverage Ratio of (x) 4.50:1.00 for the fiscal quarter ending on September 30, 2026, (y) 4.00:1.00 for the fiscal quarters ending on December 31, 2026 and March 31, 2027, and (z) 3.50:1.00 for the fiscal quarter ending on June 30, 2027 and each fiscal quarter thereafter, and (ii) a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of 3.00:1.00, in each case, tested at the end of each fiscal quarter. The Total Net Leverage Ratio covenant is subject to a 0.50:1.00 step-up for four fiscal quarters following any Material Acquisition (as defined in the Credit Agreement).

The obligations under the Credit Agreement and, at the Company’s election, any secured hedging obligations and cash management obligations owing to a Lender (or an affiliate of a Lender), are secured by substantially all of the assets of the Company. In addition, such obligations will be required to be guaranteed by, and secured by substantially all of the assets of, any future material domestic subsidiaries of the Company.

The Credit Agreement includes customary events of default that include, among other things: non-payment of principal, interest or fees; inaccuracy of representations and warranties; violation of certain covenants; cross default to certain other indebtedness; bankruptcy and insolvency events; material judgments; change of control; certain material ERISA events; and invalidity of loan documents, subject to thresholds and cure periods as set forth in the Credit Agreement. Upon the occurrence and during the continuance of an event of default, the Lenders may terminate their commitments and accelerate any outstanding obligations under the Credit Agreement and may exercise certain other rights and remedies provided for under the Credit Agreement, the other loan documents and applicable law. Notwithstanding the foregoing, acceleration will be automatic in the case of bankruptcy and insolvency events of default involving the Company. Under certain circumstances, a default interest rate will apply to all obligations during the existence of an event of default under the Credit Agreement at a per annum rate equal to 2.00% above the otherwise applicable interest rate.
