Senior Secured Credit Facility

On October 14, 2020, the Company entered into a credit agreement (as amended, the “Credit Agreement”) governing the Company’s senior secured credit facility, consisting of (i) a $575 million senior secured 7-year term loan facility (the “Term Loan Facility”) and (ii) a $200 million senior secured 5-year revolving credit facility (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Senior Secured Credit Facility”). The Credit Agreement was amended on February 23, 2021 (the “First Amendment”), on February 26, 2021 (the “Second Amendment”) and again on March 2, 2023 (the “Third Amendment”).

Revolving Credit Facility

The Company had no outstanding balance under the Revolving Credit Facility as of both June 30, 2024 and December 31, 2023, $15.9 million and $24.8 million, respectively, in standby letters of credit, and $184.1 million and $175.2 million, respectively, available to withdraw. In accordance with the Third Amendment, the Revolving Credit Facility pays interest at the Company’s election, at either (x) for SOFR Loans at Adjusted Term SOFR (as defined in the Credit Agreement) plus 3.25% or (y) for Base Rate Loans at the higher of the Prime Rate, one half of 1.00% above the Federal Funds Rate or the Adjusted Term SOFR for one-month interest period, after giving effect to any floor plus 1.00%, plus 2.25%.

Term Loan Facility

The outstanding balance on the Term Loan Facility was $236.0 million and $238.2 million as of June 30, 2024 and December 31, 2023, respectively. The Term Loan Facility is presented in the accompanying condensed consolidated balance sheets, net of debt discount and issuance costs of $9.5 million and $11.3 million as of June 30, 2024 and December 31, 2023, respectively. In accordance with the Third Amendment, the Term Loan Facility pays interest at the Company’s election, at either (x) for SOFR Loans at Adjusted Term SOFR (subject to a floor of 0.50%) plus 3.25% or (y) for Base Rate Loans at the higher of the Prime Rate, one half of 1.00% above the Federal Funds Rate or the Adjusted Term SOFR for one-month interest period, after giving effect to any floor plus 1.00%, plus 2.25%. The debt discount and issuance costs are being amortized using the effective interest method and the effective interest rate of the Term Loan Facility as of June 30, 2024, was

10.27%. The Term Loan Facility has an annual excess cash flow calculation, for which the prescribed formula did not result in requiring the Company to make an advance principal payment for the year ended December 31, 2023.

Convertible Notes

On December 3, 2021 and December 9, 2021, the Company completed a $425 million private offering ($375 million and $50 million, respectively), of its 1.00% Convertible Senior Notes due 2028 (the “Convertible Notes”), resulting in proceeds of $413.3 million ($364.7 million and $48.6 million, respectively), after deducting the original issue discount of 2.75%. The Convertible Notes were issued pursuant to an indenture, dated December 3, 2021, between the Company and U.S. Bank National Association, as trustee.

The Convertible Notes are senior unsecured obligations of the Company and will mature on December 1, 2028, unless earlier converted, redeemed, or repurchased. The Convertible Notes bear interest at a rate of 1.00% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2022. As of June 30, 2024 and December 31, 2023, the principal balance of the Convertible Notes was $425.0 million with unamortized discount and issuance costs of $8.4 million and $9.4 million, respectively, for a net carrying amount of $416.6 million and $415.6 million, respectively.

The conversion rate for the Convertible Notes was initially 41.9054 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes, which was equivalent to an initial conversion price of approximately $23.86 per share of common stock or 10.1 million shares of common stock. The Convertible Notes were not convertible during the six months ended June 30, 2024, and none have been converted to date. Also, given that the average market price of the Company’s common stock has not exceeded the exercise price since inception, there was no dilutive impact for the three and six months ended June 30, 2024.

Capped Calls

In connection with the issuances of the Convertible Notes, the Company paid $52.9 million, in aggregate, to enter into capped call option agreements to reduce the potential dilution to holders of the Company’s common stock after a conversion of the Convertible Notes. Specifically, upon the exercise of the capped call instruments issued pursuant to the agreements (the “Capped Calls”), the Company would receive shares of its common stock equal to approximately 17.8 million shares (a) multiplied by (i) the lower of $36.0200 or the then-current market price of its common stock, less (ii) the applicable exercise price, $23.86, and (b) divided by the then-current market price of its common stock. The results of this formula are that the Company would receive more shares as the market price of its common stock exceeds the exercise price and approaches the cap, which was initially, and remains currently, $36.02 per share.

Consequently, if the Convertible Notes are converted, then the number of shares to be issued by the Company would be effectively partially offset by the shares of common stock received by the Company under the Capped Calls as they are exercised. The formula above would be adjusted in the event of certain specified extraordinary events affecting the Company, including: a merger; a tender offer; nationalization, insolvency or delisting of the Company’s common stock; changes in law; failure to deliver; insolvency filing; stock splits, combinations, dividends, repurchases or similar events; or an announcement of certain of the preceding actions.

The Company can also elect to receive the equivalent value of cash in lieu of shares of common stock upon settlement, except in certain circumstances. The Capped Calls expire on December 1, 2028, and terminate

upon the occurrence of certain extraordinary events such as a merger, tender offer, nationalization, insolvency, delisting, event of default, a change in law, failure to deliver, an announcement of certain of these events, or an early conversion of the Convertible Notes. Although intended to reduce the net number of shares of common stock issued after a conversion of the Convertible Notes, the Capped Calls were separately negotiated transactions, are not a part of the terms of the Convertible Notes, and do not affect the rights of the holders of the Convertible Notes. See Note 2 – Summary of Significant Accounting Policies for information regarding the accounting for the Capped Calls.

Other Debt

Other debt consists of the debt obligations of STI (“Other Debt”). Interest rates on other debt range from 0.4% to 15.17% annually. Of the $37.7 million Other Debt balance, the equivalent of $28.7 million is denominated in Euros and $9.0 million is denominated in Brazilian Real.
