On December 7, 2021, the Company entered into a term loan credit agreement (the “Credit Agreement”) with JP Morgan Chase Bank, N.A., as administrative agent and the initial lender. The term loan issued under the Credit Agreement (the “Term Loan”), which was issued at a 3% discount and allows for a single-advance term loan B facility in the principal amount of $375.0 million, which is secured by substantially all of the Company’s and each subsidiary guarantor’s assets. Subject to certain conditions, the Company may, at any time, on one or more occasions, add one or more new classes of term facilities and/or increase the principal amount of the loans of any existing class by requesting one or more incremental term facilities. The net proceeds of the Term Loan were approximately $363.8 million after deducting an original issue discount of $11.2 million.

The Term Loan matures on December 7, 2026 and requires quarterly repayments of principal in the amount of $9.4 million. commencing June 30, 2022, and increasing to $14.1 million commencing December 31, 2025, with a remaining balloon payment of approximately $188.0 million due at maturity. During 2022, the Company will be required to make three

quarterly payments totaling $28.1 million. The Company is also required to make mandatory prepayments of principal from (i) commencing with the fiscal year ending December 31, 2022, the Company’s excess cash flow (as defined in the Credit Agreement) existing in any fiscal year and if the Senior Secured Leverage Ratio (as defined in the Credit Agreement) for such fiscal year exceeds certain predetermined limits (ii) net proceeds (as defined in the Credit Agreement) of non-ordinary course assets sales and casualty events and (iii) debt issuance proceeds (other than permitted debt under the Credit Agreement). No mandatory prepayments are due for 2021. Prepayment penalties for the Term Loan are 3% in loan year 1, 2% in loan year 2, 1% in loan year 3 and no prepayment penalties thereafter. Prepayment penalties generally do not apply to mandatory prepayment obligations under the Credit Agreement, such as prepayments due in connection with excess cash flow.

The Term Loan requires the Company to, among other things, maintain (i) a first lien net leverage ratio, determined as of the last day of any fiscal quarter, of no greater than 1.75 to 1.00 and (ii) liquidity, at any time, of at least $150.0 million. The Term Loan also contains customary affirmative and negative covenants, financial covenants, representations and warranties, events of default and other provisions. As of December 31, 2021, the Company was in compliance with all financial covenants under the Credit Agreement.

The Company may elect to borrow either term benchmark borrowings or alternate base rate borrowings. Term benchmark borrowings bear interest at a variable rate per annum equal to the Adjusted Term SOFR Rate (as defined in the Credit Agreement) (subject to a 75 basis points floor) plus an applicable margin of 700 basis points. Alternate base rate borrowings bear interest at a variable rate per annum determined using a base rate (subject to a 175 basis points floor) equal to the greatest of (i) Prime Rate (as defined in the Credit Agreement) in effect on such day, (ii) NYFRB Rate (as defined in the Credit Agreement) plus 50 basis points or (iii) the Adjusted Term SOFR Rate (as defined in the Credit Agreement) plus 100 basis points, subject to certain exceptions, plus an applicable margin of 600 basis points. As of December 31, 2021, borrowings under the Term Loan consisted entirely of term benchmark borrowings at a rate of 7.75%.

In July 2020, the Company completed a private placement of $402.5 million in aggregate principal amount of its 0.750% convertible senior notes due 2025, or 2025 Notes, and entered into an indenture, or 2025 Indenture, with respect to the 2025 Notes. The 2025 Notes accrue interest at a fixed rate of 0.750% per year, payable semiannually in arrears on February 1st and August 1st of each year, beginning on February 1, 2021. The 2025 Notes mature on August 1, 2025.

The net proceeds from the issuance of the 2025 Notes was approximately $390.0 million, after deducting commissions and the offering expenses paid by the Company. A portion of the net proceeds from the 2025 Notes was used by the Company to repurchase $185.0 million in aggregate principal amount of its outstanding 2.375% convertible senior notes due 2022 in privately negotiated transactions for a total of $211.1 million of cash (including accrued interest).

(i) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

Upon conversion, holders will receive the principal amount of their 2025 Notes and any excess conversion value, calculated based on the per share volume-weighted average price for each of the 40 consecutive trading days during the observation period (as more fully described in the 2025 Indenture). For both the principal and excess conversion value, holders may receive cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s option. The initial conversion rate for the 2025 Notes is 13.9324 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of $71.78 per share of the Company’s common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. The initial conversion price of the 2025 Notes represents a premium of approximately 32.5% to the closing sale price of $54.17 per share of the Company’s common stock on the Nasdaq Global Select Market on July 7, 2020, the date that the Company priced the private offering of the 2025 Notes.

As of December 31, 2021, the 2025 Notes had a market price of $1,113 per $1,000 principal amount. In the event of conversion, holders would forgo all future interest payments, any unpaid accrued interest and the possibility of further stock price appreciation. Upon the receipt of conversion requests, the settlement of the 2025 Notes will be paid pursuant to the terms of the 2025 Indenture. In the event that all of the 2025 Notes are converted, the Company would be required to repay the $402.5 million in principal value and any conversion premium in any combination of cash and shares of its common stock (at the Company’s option).

Prior to August 1, 2023, the Company may not redeem the 2025 Notes. On or after August 1, 2023 (but, in the case of a redemption of less than all of the outstanding 2025 Notes, no later than the 40th scheduled trading day immediately before the maturity date), the Company may redeem for cash all or part of the 2025 Notes if the last reported sale price (as defined in the 2025 Indenture) of the Company’s common stock has been at least 130% of the conversion price then in effect for (i) each of at least 20 trading days (whether or not consecutive) during any 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related notice of redemption and (ii) the trading day immediately before the date the Company sends such notice. The redemption price will equal the sum of (i) 100% of the principal amount of the 2025 Notes being redeemed, plus (ii) accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date. In addition, calling the 2025 Notes for redemption will constitute a “make-whole fundamental change” (as defined in the 2025 Indenture) and will, in certain circumstances, increase the conversion rate applicable to the conversion of such notes if it is converted in connection with the redemption. No sinking fund is provided for the 2025 Notes.

If the Company undergoes a fundamental change, as defined in the 2025 Indenture, subject to certain conditions, holders of the 2025 Notes may require the Company to repurchase for cash all or part of their 2025 Notes at a repurchase price equal to 100% of the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if a make-whole fundamental change occurs prior to August 1, 2025, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with the make-whole fundamental change.

The 2025 Notes are the Company’s general unsecured obligations that rank senior in right of payment to all of its indebtedness that is expressly subordinated in right of payment to the 2025 Notes, and equal in right of payment to the Company’s unsecured indebtedness. The 2025 Notes are also effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to any debt or other liabilities (including trade payables) of the Company’s subsidiaries.

While the 2025 Notes are currently classified on the Company’s consolidated balance sheet at December 31, 2021 as long-term debt, the future convertibility and resulting balance sheet classification of this liability is monitored at each quarterly reporting date and is analyzed dependent upon market prices of the Company’s common stock during the prescribed measurement periods. In the event that the holders of the 2025 Notes have the election to convert the 2025 Notes at any time during the prescribed measurement period, the 2025 Notes would then be considered a current obligation and classified as such.

Under ASC 470-20, Debt with Conversion and Other Options, an entity must separately account for the liability and equity components of convertible debt instruments (such as the 2025 Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The liability component of the instrument is valued in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. The initial carrying value of the liability component of $314.7 million was calculated using a 5.78% assumed borrowing rate. The equity component of $87.8 million, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 2025 Notes and is recorded in additional paid-in capital on the consolidated balance sheet at the issuance date. The equity component is treated as a discount on the liability component of the 2025 Notes, which is amortized over the five-year term of the 2025 Notes using the effective interest rate method. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. A deferred tax liability was recognized in the amount of $20.5 million, with the offsetting amount recorded in additional paid-in capital. See Note 16, Income Taxes, for information regarding the Company’s deferred taxes.

The Company allocated the total transaction costs of approximately $12.5 million related to the issuance of the 2025 Notes to the liability and equity components of the 2025 Notes based on their relative values. Transaction costs attributable to the liability component are amortized to interest expense over the five-year term of the 2025 Notes, and transaction costs attributable to the equity component totaling $2.7 million are netted with the equity component in stockholders’ equity.

The 2025 Notes do not contain any financial or operating covenants or any restrictions on the payment of dividends, the issuance of other indebtedness or the issuance or repurchase of securities by the Company. The 2025 Indenture contains customary events of default with respect to the 2025 Notes, including that upon certain events of default, 100% of the principal and accrued and unpaid interest on the 2025 Notes will automatically become due and payable.

Prior to the Flexion Acquisition, on May 2, 2017, Flexion issued an aggregate of $201.3 million principal amount of 3.375% convertible senior notes due 2024 (the “Flexion 2024 Notes”), pursuant to the indenture, dated as of May 2, 2017 (the “Original Flexion Indenture”), between Flexion and Wells Fargo Bank, National Association, as trustee (the “Flexion Trustee”), as supplemented by the First Supplemental Indenture, dated as of November 19, 2021, between Flexion and the Flexion Trustee (the “First Supplemental Flexion Indenture” and, together with the Original Flexion Indenture, the “Flexion Indenture”). The Flexion 2024 Notes have a maturity date of May 1, 2024, are unsecured, and accrue interest at a rate of 3.375% per annum, payable semi-annually on May 1 and November 1 of each year. Upon the Flexion Acquisition, the principal was assumed and recorded at fair value by the Company.

Upon conversion of the Flexion 2024 Notes, at the election of each holder thereof, each Flexion 2024 Note was convertible into cash, shares of Flexion’s common stock, or a combination thereof, at Flexion’s election, at a conversion rate of approximately 37.3413 shares of Flexion common stock per $1,000 principal amount of the Flexion 2024 Notes, which corresponded to an initial conversion price of approximately $26.78 per share of Flexion’s common stock. As a result of the Flexion Acquisition, and in connection with the Notice (as defined below), holders of the Flexion 2024 Notes became entitled to certain Flexion Acquisition-related conversion and repurchase rights, as discussed below. In addition, as a result of the Flexion Acquisition and as discussed in more detail below, any future conversion rights are subject to the occurrence of any future events giving rise to such conversion rights under the Flexion Indenture.

On December 6, 2021, as a result of the Flexion Acquisition and in accordance with the Flexion Indenture, Flexion provided a Fundamental Change Company Notice and Offer to Purchase (the “Notice”) to the holders of the Flexion 2024 Notes and offered to repurchase for cash all of the outstanding Flexion 2024 Notes, at a repurchase price in cash equal to 100% of the principal amount of the Flexion 2024 Notes being repurchased, plus accrued and unpaid interest thereon to, but excluding, January 7, 2022, subject to the terms and conditions set forth therein. The offer to purchase expired at 5:00 p.m., New York City time, on January 6, 2022, as scheduled.

Any holder that did not exercise its repurchase right in accordance with the terms of the Notice retained the conversion rights associated with such holder’s Flexion 2024 Notes under the Flexion Indenture. For conversion of Flexion 2024 Notes in connection with the Fundamental Change and the Make-Whole Fundamental Change (each as defined in the Flexion Indenture) resulting from the Flexion Acquisition, each $1,000 principal amount of the Flexion 2024 Notes was convertible into (i) $317.40 in cash and (ii) 37.3413 CVRs, based on the conversion rate of 37.3413, prior to 5:00 p.m., New York City time, on January 7, 2022. Alternatively, holders could retain their Flexion 2024 Notes and such Flexion 2024 Notes would remain outstanding subject to their existing terms, including with respect to a holder’s right to receive interest payments on the Flexion 2024 Notes and exercise any future conversion rights that may arise under the Flexion Indenture.

On January 7, 2022, following the expiration of the offer to purchase, the Company accepted the $192.6 million aggregate principal amount of Flexion 2024 Notes that were validly tendered (and not validly withdrawn). No Flexion 2024 Notes were converted in connection with the Notice. The remaining principal outstanding is $8.6 million as of the date of this report.

In March 2017, the Company completed a private placement of $345.0 million in aggregate principal amount of 2.375% convertible senior notes due 2022, or 2022 Notes, and entered into an indenture, or 2022 Indenture, with respect to the 2022 Notes. The 2022 Notes accrue interest at a fixed rate of 2.375% per year, payable semiannually in arrears on April 1st and October 1st of each year. The 2022 Notes mature on April 1, 2022. As discussed above, in July 2020, the Company used part of the net proceeds from the issuance of the 2025 Notes to repurchase $185.0 million aggregate principal amount of the 2022 Notes in privately negotiated transactions for an aggregate of $211.1 million in cash (including accrued interest). The partial repurchase of the 2022 Notes resulted in an $8.1 million loss on early extinguishment of debt during the year ended December 31, 2020.

Holders may convert their 2022 Notes at any time through the close of business on the second scheduled trading day immediately preceding April 1, 2022. Upon conversion, holders will receive the principal amount of their 2022 Notes and any excess conversion value, calculated based on the per share volume-weighted average price for each of the 40 consecutive trading days during the observation period (as more fully described in the 2022 Indenture). For both the principal and excess conversion value, holders may receive cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s option. The initial conversion rate for the 2022 Notes is 14.9491 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of $66.89 per share of the Company’s common stock. The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. The initial conversion price of the 2022 Notes represents a premium of approximately 37.5% to the closing sale price of $48.65 per share of the Company’s common stock on the Nasdaq Global Select Market on March 7, 2017, the date that the Company priced the private offering of the 2022 Notes.

As of December 31, 2021, the 2022 Notes had a market price of $1,039 per $1,000 principal amount. In the event of conversion, holders would forgo all future interest payments, any unpaid accrued interest and the possibility of stock price appreciation. Upon the receipt of conversion requests, the settlement of the 2022 Notes will be paid pursuant to the terms of the 2022 Indenture. In the event that all of the 2022 Notes are settled, the Company would be required to repay the remaining $160.0 million in principal value and any conversion premium in any combination of cash and shares of its common stock (at the Company’s option).

As of April 1, 2020, the Company may redeem for cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s option, all or part of the 2022 Notes if the last reported sale price (as defined in the 2022 Indenture) of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period ending within five

trading days prior to the date on which the Company provides notice of redemption. This condition was not met during the quarter ended December 31, 2021. The redemption price will equal the sum of (i) 100% of the principal amount of the 2022 Notes being redeemed, plus (ii) accrued and unpaid interest, including additional interest, if any, to, but excluding, the redemption date. In addition, calling the 2022 Notes for redemption will constitute a “make-whole fundamental change” (as defined in the 2022 Indenture) and will, in certain circumstances, increase the conversion rate applicable to the conversion of such notes if it is converted in connection with the redemption. No sinking fund is provided for the 2022 Notes.

If the Company undergoes a fundamental change, as defined in the 2022 Indenture, subject to certain conditions, holders of the 2022 Notes may require the Company to repurchase for cash all or part of their 2022 Notes at a repurchase price equal to 100% of the principal amount of the 2022 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if a make-whole fundamental change occurs prior to April 1, 2022, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with the make-whole fundamental change.

The 2022 Notes are the Company’s general unsecured obligations that rank senior in right of payment to all of its indebtedness that is expressly subordinated in right of payment to the 2022 Notes, and equal in right of payment to the Company’s unsecured indebtedness. The 2022 Notes are also effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and are structurally subordinated to any debt or other liabilities (trade payables) of the Company’s subsidiaries.

Under ASC 470-20, Debt with Conversion and Other Options, an entity must separately account for the liability and equity components of convertible debt instruments (such as the 2022 Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The liability component of the instrument is valued in a manner that reflects the market interest rate for a similar nonconvertible instrument at the date of issuance. The initial carrying value of the liability component of $274.1 million was calculated using a 7.45% assumed borrowing rate. The equity component of $70.9 million, representing the conversion option, was determined by deducting the fair value of the liability component from the par value of the 2022 Notes and was recorded in additional paid-in capital on the consolidated balance sheet at the issuance date. That equity component is treated as a discount on the liability component of the 2022 Notes, which is amortized over the five-year term of the 2022 Notes using the effective interest rate method. The equity component is not re-measured as long as it continues to meet the conditions for equity classification.

The Company allocated the total transaction costs of $11.0 million related to the issuance of the 2022 Notes to the liability and equity components of the 2022 Notes based on their relative values. Transaction costs attributable to the liability component are amortized to interest expense over the five-year term of the 2022 Notes, and transaction costs attributable to the equity component are netted with the equity component in stockholders’ equity.

The 2022 Notes do not contain any financial or operating covenants or any restrictions on the payment of dividends, the issuance of other indebtedness or the issuance or repurchase of securities by the Company. The 2022 Indenture contains customary events of default with respect to the 2022 Notes, including that upon certain events of default, 100% of the principal and accrued and unpaid interest on the 2022 Notes will automatically become due and payable.
