(1) Amounts outstanding under the 2024 Credit Facility as of December 31, 2024 and the 2018 Credit Facility as of December 31, 2023. Senior Secured Credit Facility On August 16, 2018, the Company entered into a $1.25 billion senior secured credit facility, or the 2018 Credit Facility, consisting of a $250.0 million term loan A, or the 2018 Term Loan A, a $750.0 million term loan B, or the 2018 Term Loan B, and a $250.0 million revolving credit facility, or the 2018 Revolving Credit Facility, with a syndicate of financial institutions as lenders. Subsequently, the 2018 Credit Facility was amended in a series of amendments that, as of March 31, 2024, among other things, increased the borrowing capacity of the 2018 Term Loan A to a total of $286.2 million and the 2018 Revolving Credit Facility to a total of $330.0 million and establishing the Secured Overnight Financing Rate, or SOFR, for interest rate purposes under the 2018 Credit Facility. Borrowings utilizing SOFR under both the 2018 Term Loan A and 2018 Revolving Credit Facility, bore interest at, depending on the Company’s total leverage ratio, either the Adjusted Term SOFR, which is the rate per annum equal to Term SOFR plus a rate adjustment based on interest periods of one month, three months, six months and twelve months tenors equaling to approximately 0.11%, 0.26%, 0.43% and 0.72%, respectively, plus a margin of between 1.75% and 2.25%, or the base rate, which represented the highest of the Federal Funds Rate plus 0.50%, one-month Adjusted Term SOFR plus 1.00%, and the prime rate quoted by The Wall Street Journal, plus a margin of between 0.75% and 1.25%. Borrowings utilizing SOFR under the 2018 Term Loan B bore interest at either, the Adjusted Term SOFR plus a margin of 2.50%, or the base rate plus a margin of 1.50%. The Adjusted Term SOFR was subject to a floor of 0.00% and the base rate was subject to a floor of 1.00%. The Company paid commitment fees on the 2018 Revolving Credit Facility of, depending on the Company’s total leverage ratio, between 0.25% to 0.35% per annum on the undrawn portion of the 2018 Revolving Credit Facility. The maturity date of both the 2018 Term Loan A and 2018 Revolving Credit Facility was March 19, 2025. The 2018 Term Loan B maturity date was August 18, 2025. The 2018 Credit Facility required the Company to comply with a leverage ratio. The 2018 Credit Facility also contained affirmative and negative covenants customary for financings of this type, including, among other things, limitations or prohibitions on repurchasing common shares, declaring and paying dividends and other distributions, redeeming and repurchasing certain other indebtedness, making loans and investments, incurring additional indebtedness, granting liens, and effecting mergers, asset sales and transactions with affiliates. In addition, the 2018 Credit Facility contained customary events of default. On April 12, 2024, concurrently with the issuance of the $800.0 million aggregate principal amount of senior secured notes, or the 2029 Secured Notes, as described further below, the Company entered into the eighth amendment to the 2018 Credit Facility. The eighth amendment to the 2018 Credit Facility, among other things, refinanced and replaced in full the 2018 Credit Facility with, (i) a Term Loan B Facility, or the 2024 Term Loan B, with an aggregate principal amount of $400.0 million and (ii) a revolving credit facility, or the 2024 Revolving Credit Facility, with an aggregate principal amount of $400.0 million, collectively the 2024 Credit Facility. All obligations under the 2024 Credit Facility are unconditionally guaranteed by certain direct and indirect wholly-owned subsidiaries of Herbalife Ltd. and secured on a senior secured basis by the equity interests of certain of Herbalife Ltd.’s subsidiaries and substantially all of the assets of the domestic loan parties. Interest is due at least quarterly on amounts outstanding under the 2024 Credit Facility. The 2024 Term Loan B Facility was issued to the lenders at a 7.00% discount, or $28.0 million, and the Company incurred approximately $10.3 million of debt issuance costs in connection with the 2024 Credit Facility. The Company may prepay the 2024 Term Loan B at a 102% premium at any time on or before the first anniversary, 101% premium following the first anniversary and on or prior to the second anniversary, and, solely in connection with a repricing event, at a 101% premium after the second anniversary but on or prior to the third anniversary, and generally at no premium thereafter. The 2024 Term Loan B requires quarterly payments equal to 5.0% of the aggregate principal amount of the 2024 Term Loan B per annum, commencing in September 2024. In addition, pursuant to the terms of the 2024 Credit Facility, beginning in fiscal year 2025, the Company may be required to make mandatory prepayments towards the 2024 Term Loan B based on an annual excess cash flow calculation and consolidated leverage ratio as defined under the terms of the 2024 Credit Facility. Proceeds from the 2024 Term Loan B together with the proceeds from the 2029 Secured Notes were used to repay indebtedness, including all borrowings outstanding under the 2018 Credit Facility, effectively terminating its $228.9 million outstanding principal balance on the 2018 Term Loan A, and repaying $584.3 million on the 2018 Term Loan B, $170.0 million on the 2018 Revolving Credit Facility, and a portion of the 2025 Notes described further below. For accounting purposes, pursuant to ASC 470, Debt, these transactions were accounted for as an extinguishment of the 2018 Credit Facility. As a result, the Company recognized $981.0 million as a reduction to long-term debt representing the carrying value of the 2018 Credit Facility repaid in full in the second quarter of 2024. The Company also recognized a loss on extinguishment of approximately $2.5 million, as a result, which was recorded in other expense, net within the Company’s consolidated statement of income during the second quarter of 2024. Borrowings utilizing SOFR under the 2024 Credit Facility use Adjusted Term SOFR. The applicable interest rates on the Company’s borrowings under the 2024 Term Loan B, as amended, bear interest at either, the Adjusted Term SOFR plus a margin of 6.75%, or the base rate plus a margin of 5.75%. The 2024 Term Loan B Facility matures upon the earlier of (i) April 12, 2029, or (ii) March 16, 2028 if the outstanding principal on the 2028 Convertible Notes, as defined below, exceeds $100.0 million and the Company exceeds certain leverage ratios as of that date, or (iii) June 2, 2025 if the outstanding principal on the 2025 Notes, as defined below, exceeds $200.0 million on such date. Effective after April 12, 2024, depending on the Company’s total leverage ratio, borrowings under the 2024 Revolving Credit Facility bear interest at either the Adjusted Term SOFR plus a margin of between 5.50% and 6.50%, or the base rate plus a margin of between 4.50% and 5.50%. The Company pays a commitment fee on the 2024 Revolving Credit Facility of, depending on the Company’s total leverage ratio, between 0.35% to 0.45% per annum on the undrawn portion of the 2024 Revolving Credit Facility. The 2024 Revolving Credit Facility matures upon the earlier of (i) April 12, 2028, (ii) December 16, 2027 if the outstanding principal on the 2028 Convertible Notes, as defined below, exceeds $100.0 million and the Company exceeds certain leverage ratios as of that date, or (iii) March 3, 2025 if the outstanding principal on the 2025 Notes, as defined below, exceeds $200.0 million on such date. The 2024 Credit Facility contains affirmative, negative and financial covenants customary for financings of this type, including, among other things, limitations or prohibitions on declaring and paying dividends and other distributions, redeeming and repurchasing certain other indebtedness, making loans and investments, incurring additional indebtedness, granting liens, and effecting mergers, asset sales and transactions with affiliates. In addition, the 2024 Credit Facility contains customary events of default. The 2024 Revolving Credit Facility requires the Company to maintain a maximum total leverage ratio of 4.50:1.00 through December 31, 2024, stepping down to 4.25:1.00 on March 31, 2025 and 4.00:1.00 at September 30, 2025 and thereafter. The financial covenants also include a maximum first lien net leverage ratio of 2.50:1.00, a minimum fixed charge coverage ratio of 2.00:1.00, and a minimum liquidity of $200.0 million of revolver availability and accessible cash.

The Company is permitted to make voluntary prepayments, subject to the premiums as discussed above. These prepayments, if any, will be applied against remaining quarterly installments owed under the 2024 Term Loan B in order of maturity with the remaining principal due upon maturity, unless directed otherwise by the Company. Pursuant to the terms of the 2018 Credit Facility excess cash flow clause and based on the 2023 excess cash flow calculation and consolidated leverage ratio as of December 31, 2023, as described and defined under the terms of the 2018 Credit Facility, the Company made a $66.3 million mandatory prepayment towards the 2018 Term Loan B during the first quarter of 2024.

As a result of the issued but undrawn letter of credit, as of December 31, 2024 and December 31, 2023, the remaining available borrowing capacity under the 2024 Revolving Credit Facility and 2018 Revolving Credit Facility, respectively, was approximately $355 million and approximately $285 million, respectively.

In addition, the 2029 Secured Notes contain customary events of default. The 2029 Secured Notes were sold at a 2.702% discount to par, or $21.6 million, and the Company incurred approximately $13.9 million of issuance cost in connection with the issuance of the 2029 Secured Notes. The total of $35.5 million which was recorded as a debt discount on the Company's consolidated balance sheet, is being amortized over the contractual term of the 2029 Secured Notes using the effective-interest method. As of December 31, 2024, the outstanding principal on the 2029 Secured Notes was $800.0 million, the unamortized debt discount and debt issuance costs were $3 1.8 million, and the carrying amount was $768.2 million, which was recorded to long-term debt within the Company’s consolidated balance sheet. The fair value of the 2029 Secured Notes was approximately $851.3 million as of December 31, 2024, and was determined by utilizing over-the-counter market quotes and yield curves, which are considered Level 2 inputs as defined in Note 13, Fair Value Measurements. During the year ended December 31, 2024, the Company recognized $74.2 million of interest expense relating to the 2029 Secured Notes, which included $2.3 million relating to non-cash interest expense relating to the debt discount and $1.5 million relating to amortization of debt issuance costs. Convertible Senior Notes due 2024 In March 2018, the Company issued $550.0 million aggregate principal amount of convertible senior notes, or the 2024 Convertible Notes, in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2024 Convertible Notes were senior unsecured obligations which ranked effectively subordinate to any of the Company’s existing and future secured indebtedness, including amounts outstanding under the 2018 Credit Facility, to the extent of the value of the assets securing such indebtedness. The 2024 Convertible Notes paid interest at a rate of 2.625% per annum payable semiannually in arrears on March 15 and September 15 of each year, beginning on September 15, 2018. Unless redeemed, repurchased or converted in accordance with their terms prior to such date, the 2024 Convertible Notes matured on March 15, 2024. On and after December 15, 2023, holders could convert their 2024 Convertible Notes at any time, regardless of the circumstances. In December 2021, the Company made an irrevocable election under the indenture governing the 2024 Convertible Notes to require the principal portion of the 2024 Convertible Notes to be settled in cash and any excess in shares or cash. Upon conversion, the 2024 Convertible Notes would have been settled in cash and, if applicable, the Company’s common shares, based on the applicable conversion rate at such time. The 2024 Convertible Notes had an initial conversion rate of 16.0056 common shares per $1,000 principal amount of the 2024 Convertible Notes, or an initial conversion price of approximately $62.48 per common share. The conversion rate was subject to adjustment upon the occurrence of certain events and was 16.0467 common shares per $1,000 principal amount of the 2024 Convertible Notes, or a conversion price of approximately $62.32 per common share, as of March 15, 2024, prior to its maturity. In March 2018, prior to the adoption of ASU 2020-06 as described further below, the $550.0 million aggregate principal amount of the 2024 Convertible Notes were initially allocated between long-term debt, or liability component, and additional paid-in capital, or equity component, within the Company’s consolidated balance sheet at $410.1 million and $139.9 million, respectively. The liability component was measured using the nonconvertible debt interest rate. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the face value of the 2024 Convertible Notes as a whole. Since the Company was required to settle these 2024 Convertible Notes at face value at or prior to maturity, this liability component was being accreted up to its face value prior to the adoption of ASU 2020-06, resulting in additional non-cash interest expense being recognized within the Company’s consolidated statements of income while the 2024 Convertible Notes remained outstanding. Prior to the adoption of ASU 2020-06, the effective-interest rate on the 2024 Convertible Notes was approximately 8.4% per annum. The equity component was not to be remeasured as long as it continued to meet the conditions for equity classification. The Company incurred approximately $12.9 million of issuance costs during the first quarter of 2018 relating to the issuance of the 2024 Convertible Notes. Of the $12.9 million issuance costs incurred, $9.6 million and $3.3 million were recorded as debt issuance costs and additional paid-in capital, respectively, in proportion to the allocation of the proceeds of the 2024 Convertible Notes prior to the adoption of ASU 2020-06. The $9.6 million of debt issuance costs, which was recorded as an additional debt discount on the Company’s consolidated balance sheet, was amortized over the contractual term of the 2024 Convertible Notes using the effective-interest method. The Company adopted ASU 2020-06 during the first quarter of 2022 using the modified retrospective method and recognized a cumulative-effect adjustment to the opening balance of accumulated deficit in the period of adoption. As a result of adopting ASU 2020-06, on January 1, 2022, the Company increased long-term debt by approximately $59.1 million, reduced paid-in capital in excess of par value by approximately $136.7 million, and decreased accumulated deficit by approximately $77.6 million within its consolidated balance sheet. In addition, the effective-interest on the 2024 Convertible Notes was approximately 3.1% per annum. In December 2022, the Company issued $277.5 million aggregate principal amount of new convertible senior notes due 2028, or the 2028 Convertible Notes as described below, and subsequently used the proceeds, to repurchase $287.5 million of its existing 2024 Convertible Notes from a limited number of holders in privately negotiated transactions for an aggregate purchase price of $274.9 million, which included $1.7 million of accrued interest. For accounting purposes, pursuant to ASC 470, Debt, these transactions were accounted for as an extinguishment of 2024 Convertible Notes and an issuance of new 2028 Convertible Notes. As a result, the Company recognized $286.0 million as a reduction to long-term debt representing the carrying value of the repurchased 2024 Convertible Notes. The $12.8 million d ifference between the cash paid and carrying value of the repurchased 2024 Convertible Notes was recognized as a gain on the extinguishment of debt and is recorded in other (income) expense, net within the Company’s consolidated statement of income during the fourth quarter of 2022. The accounting impact of the new 2028 Convertible Notes is described in further detail below. In August 2023, the Company repurchased $65.5 million of its existing 2024 Convertible Notes through open market purchases for an aggregate purchase price of $65.1 million, which included $0.8 million of accrued interest. For accounting purposes, pursuant to ASC 470, Debt, these transactions were accounted for as an extinguishment of the 2024 Convertible Notes. As a result, the Company recognized $65.3 million as a reduction to current portion of long-term debt representing the carrying value of the repurchased 2024 Convertible Notes. The $1.0 million d ifference between the cash paid and carrying value of the repurchased 2024 Convertible Notes was recognized as a gain on the extinguishment of debt and is recorded in other income, net within the Company’s consolidated statement of income during the third quarter of 2023. On March 15, 2024, the 2024 Convertible Notes matured and the Company repaid the remaining $197.0 million outstanding principal in cash, as well as $2.6 million of accrued interest. As a result, the Company recognized $197.0 million as a reduction to current portion of long-term debt representing the carrying value of the repurchased 2024 Convertible Notes. As of December 31, 2023, the remaining outstanding principal on the 2024 Convertible Notes was $197.0 million, the unamortized debt issuance costs were $0.2 million, and the carrying amount was $196.8 million, which was recorded to current portion of long-term debt within the Company’s consolidated balance sheet. The fair value of the 2024 Convertible Notes was approximately $196.2 million as of December 31, 2023, and was determined by utilizing over-the-counter market quotes, which are considered Level 2 inputs as defined in Note 13, Fair Value Measurements. As a result of adopting ASU 2020-06 during the first quarter of 2022, as it relates to the 2024 Convertible Notes, the Company did no t recognize non-cash interest expense relating to the debt discount. During the years ended December 31, 2024, 2023, and 2022, the Company recognized $1.2 million, $7.2 million, and $16.3 million, respectively, of interest expense relating to the 2024 Convertible Notes, which included $0.2 million, $1.0 million, and $2.1 million, respectively, relating to amortization of debt issuance costs. Convertible Senior Notes due 2028 In December 2022, the Company issued $250.0 million aggregate principal amount of convertible senior notes in a private offering to qualified institutional buyers, pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company granted an option to the initial purchasers to purchase up to an additional $37.5 million aggregate principal amount of 2028 Convertible Notes, of which $27.5 million was exercised during December 2022, resulting in a total issuance of $277.5 million aggregate principal amount of 2028 Convertible Notes. The 2028 Convertible Notes are senior unsecured obligations which rank effectively subordinate to any of the Company’s existing and future secured indebtedness, including amounts outstanding under the 2024 Credit Facility, to the extent of the value of the assets securing such indebtedness. The 2028 Convertible Notes pay interest at a rate of 4.25% per annum payable semiannually in arrears on June 15 and December 15 of each year, beginning on June 15, 2023.
