9.5% Non-Recourse Notes Due 2035

On February 21, 2020, Theravance Biopharma R&D, Inc. (“Theravance R&D”), a wholly-owned subsidiary of the Company, and Triple Royalty Sub II LLC (the “Issuer II” or “Triple II”), a wholly-owned subsidiary of Theravance Biopharma R&D, entered into certain note purchase agreements (“Note Purchase Agreements”) with certain note purchasers (“Note Purchasers”), relating to the private placement by Issuer II of $400.0 million 9.5% Fixed Rate Term Notes due on or before 2035 (the “Non-Recourse 2035 Notes”). Ninety-five percent of the Non-Recourse 2035 Notes were sold to the Note Purchasers pursuant to the Note Purchase Agreements. The remaining 5% of the Non-Recourse 2035 Notes (the “Retained Notes”) were retained by the Company to comply with Regulation RR — Credit Risk Retention (17 C.F.R. Part 246). The Retained Notes are eliminated in the Company’s consolidated financial statements. The transaction closed on February 28, 2020.

The Non-Recourse 2035 Notes are secured by all of Issuer II’s right, title and interest as a holder of certain membership interests (the “Issuer II Class C Units”) in Theravance Respiratory Company, LLC (“TRC”). TRC holds the right to receive upward-tiering royalties ranging from 6.5% to 10% on worldwide net sales of TRELEGY, and the Company holds an 85% economic interest in TRC. The Issuer II Class C Units represent 75% of the Company's 85% economic interest, which equates to 63.75% of the economic interests in TRC.

The source of principal and interest payments for the Non-Recourse 2035 Notes are the future royalty payments generated from the TRELEGY program, and as a result, the holders of the Non-Recourse 2035 Notes have no recourse against the Company even if the TRELEGY payments are insufficient to cover the principal and interest payments for

the Non-Recourse 2035 Notes. Prior to and including the December 5, 2024 payment date, in the event that the distributions received by the Issuer II from TRC in a quarter is less than the interest accrued for that quarter, the principal amount of the Non-Recourse 2035 Notes will increase by the interest shortfall amount for that quarter. The net principal amount of the Non-Recourse 2035 Notes increased by $17.6 million which represented the shortfall between the distributions received from TRC and the total interest payments due during the year ended December 31, 2020. While the holders of the Non-Recourse 2035 Notes have no recourse against the Company, the terms of the Non-Recourse 2035 Notes also provide that the Company, at its option, may satisfy the quarterly interest payment obligations by making a capital contribution to the Issuer II.

The Non-Recourse 2035 Notes are not convertible into Company equity and have no security interest in nor rights under any agreement with Glaxo Group Limited or one of its affiliates (“GSK”). See “Note 9. Theravance Respiratory Company, LLC” for further information regarding GSK. The Non-Recourse 2035 Notes may be redeemed by Issuer II on and after February 28, 2022, in whole or in part, at specified redemption premiums. The Non-Recourse 2035 Notes bear an annual interest rate of 9.5%, with interest and principal paid quarterly beginning June 5, 2020. Since the principal and interest payments on the Non-Recourse 2035 Notes are ultimately based on royalties from TRELEGY product sales, which will vary from quarter to quarter, the Non-Recourse 2035 Notes may be repaid prior to the final maturity date in 2035. Following the redemption or repayment of the Non-Recourse 2035 Notes, all TRELEGY-related pledged cash flows will revert back to the Company.

The portion of the Non-Recourse 2035 Notes classified as a current liability, if any, is based on the amount of royalties received, or receivable, as of December 31, 2020, that are expected to be used to make a principal repayment on the Non-Recourse 2035 Notes within the next 12 months.

As of December 31, 2020, the net principal and estimated fair value of the Non-Recourse 2035 Notes were $397.6 million and $399.6 million, respectively. The inputs to determine fair value of the Non-Recourse 2035 Notes are categorized as Level 2 inputs. Level 2 inputs include quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

9.0% Non-Recourse Notes Due 2033

In November 2018, the Company entered into note purchase agreements relating to the private placement of $250.0 million aggregate principal amount of 9.0% non-recourse notes, due on or before 2033 (the “Non-Recourse 2033 Notes”) issued by the Company’s wholly-owned subsidiary, Triple Royalty Sub LLC (the “Issuer”). On February 28, 2020, the Company refinanced the Non-Recourse 2033 Notes by issuing the Non-Recourse 2035 Notes and a portion of those proceeds were used to repay, in full, the remaining outstanding balance of the Company’s Non-Recourse 2033 Notes. Pursuant to the terms of the Non-Recourse 2033 Notes, the Company paid a debt redemption premium of 5% of the outstanding principal as of the refinancing date.

The refinancing of the Non-Recourse 2033 Notes involved multiple lenders who were considered members of a loan syndicate. To determine whether the refinancing was to be accounted for as a debt extinguishment or modification, the Company considered whether the lenders involved in the Non-Recourse 2033 Notes and the Non-Recourse 2035 Notes remained the same or changed and whether the change in debt terms was substantial. The debt terms are considered substantially different if the present value of the cash inflows and outflows of the Non-Recourse 2035 Notes, including all principal increases and lender fees on the refinancing date, was at least 10% different from the present value of the remaining cash inflows and outflows of the Non-Recourse 2033 Notes (the “10% Test”). The Company performed the 10% Test for each individual lender participating in the loan syndication by assuming the exercise and non-exercise of the prepayment option. The cash flow assumption generating the smaller change was used as the basis for determining whether the 10% threshold was met. For existing lenders who participated in the Non-Recourse 2035 Notes as part of the new loan syndicate, the refinancing was accounted for as an extinguishment or a modification depending upon whether the change in the cash flows was more or less than 10%, respectively. Amounts due to lenders of the Non-Recourse 2033 Note offering who did not participate in the Non-Recourse 2035 Notes were accounted for as a debt extinguishment.

For debt determined to be extinguished, the total unamortized deferred financing costs and the associated redemption premium of $15.5 million were expensed as “Loss on extinguishment of debt” within the consolidated statements of operations for the year ended December 31, 2020. In addition, $0.3 million of new third-party costs were expensed, and $4.4 million of new creditor fees were capitalized as debt discount. For debt determined to be modified, $0.5 million of new creditor fees were expensed, and the related unamortized deferred financing costs of $1.8 million, as of February 28, 2020, will continue to be amortized through the remaining term of the Non-Recourse 2035 Notes.

3.25% Convertible Senior Notes Due 2023

In November 2016, the Company completed an underwritten public offering of $230.0 million of 3.25% convertible senior notes, due 2023 (the "Convertible Senior 2023 Notes") for net proceeds of $222.5 million. The Company incurred $7.5 million in debt issuance costs, which are being amortized to interest expense over the estimated life of the Convertible Senior 2023 Notes. The Convertible Senior 2023 Notes bear an annual interest rate of 3.25%, payable semi-annually in arrears, on November 1 and May 1 of each year.

The Convertible Senior 2023 Notes are senior unsecured obligations and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Convertible Senior 2023 Notes; equal in right of payment to any of the Company’s indebtedness that is not so subordinated; 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 structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

The Convertible Senior 2023 Notes will mature on November 1, 2023, unless earlier redeemed or repurchased by the Company or converted. Holders may convert their Convertible Senior 2023 Notes into ordinary shares at an initial conversion rate of 29.0276 shares for each $1,000 principal amount of Convertible Senior 2023 Notes, which is equivalent to an initial conversion price of approximately $34.45 per share, subject to adjustment, in certain circumstances (including upon the occurrence of a fundamental change), at any time prior to the close of business on the second business day immediately preceding the maturity date. Upon the occurrence of a fundamental change involving the Company, holders of the Convertible Senior 2023 Notes may require the Company to repurchase all or a portion of their Convertible Senior 2023 Notes for cash at a redemption price equal to 100% of the principal amount of the Convertible Senior 2023 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, in some circumstances, the conversion rate of the Convertible Senior 2023 Notes will increase with a make whole premium for conversions in connection with certain fundamental changes.

The debt issuance costs related to the Convertible Senior 2023 Notes offering were capitalized as deferred financing costs and presented as a reduction of the carrying value of the financial liability on the Company’s consolidated balance sheets at December 31, 2020 and 2019.

The estimated fair value of the Convertible Senior 2023 Notes was $217.9 million and $236.0 million at December 31, 2020 and 2019, respectively. The estimated fair value was primarily based upon the underlying price of Theravance Biopharma’s publicly traded shares and other observable inputs as of December 31, 2020 and 2019. The inputs to determine fair value of the Convertible Senior 2023 Notes are categorized as Level 2 inputs. Level 2 inputs include quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
