On December 24, 2019, the Company completed the private exchange of $276.0 million aggregate principal amount of its outstanding 1.75% Convertible Senior Notes due 2021 (the “2021 Notes”) for a combination of newly issued 6.00% Convertible Senior Secured Notes due 2024 (the “2024 Notes”) and cash. For each $1,000 principal amount of exchanged 2021 Notes, the Company issued $750 principal amount of the 2024 Notes and made a cash payment of $200 (the “Exchange”). In the aggregate, the Company issued approximately $207.0 million aggregate principal amount of the 2024 Notes and paid approximate $55.2 million in cash to participating holders. The Exchange was conducted with a limited number of institutional holders of the 2021 Notes pursuant to Exchange Agreements dated as of December 20, 2019. The 2021 Notes received by the Company in the Exchange were cancelled in accordance with their terms. Accordingly, upon completion of the Exchange, $69.0 million of the 2021 Notes remained outstanding. On June 15, 2021, the Company repaid the outstanding balance of the 2021 Notes at their maturity date using cash on hand.

The 2024 Notes were issued pursuant to an Indenture, dated as of December 23, 2019, among the Company, its wholly owned subsidiary, Civitas Therapeutics, Inc. (along with any domestic subsidiaries acquired or formed after the date of issuance, the “Guarantors”), and Wilmington Trust, National Association, as trustee and collateral agent (the “2024 Indenture”). The 2024 Notes are senior obligations of the Company and the Guarantors, secured by a first priority security interest in substantially all of the assets of the Company and the Guarantors, subject to certain exceptions described in the Security Agreement, dated as of December 23, 2019, between the grantors party thereto and Wilmington Trust, National Association, as collateral agent.

The 2024 Notes will mature on December 1, 2024 unless earlier converted in accordance with their terms prior to such date. Interest on the 2024 Notes is payable semi-annually in arrears at a rate of 6.00% per annum on each June 1 and December 1, beginning on June 1, 2020. Under the 2024 Indenture, the Company may elect to pay interest in cash or shares of the Company’s common stock, subject to the satisfaction of certain conditions. If the Company elects to pay interest in shares of common stock, such common stock will have a per share value equal to 95% of the daily volume-weighted average price for the 10 trading days ending on and including the trading day immediately preceding the relevant interest payment date. Based on the current market price of the Company’s common stock and the Company’s remaining authorized shares of common stock that are not reserved for other purposes, the Company believes that for the foreseeable future interest payments on the 2024 notes will have to be made in cash.

The 2024 Notes are convertible at the option of the holder into shares of common stock of the Company at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The adjusted conversion rate for the 2024 Notes is 47.6190 shares of the Company’s common stock per $1,000 principal amount of 2024 Notes, representing an adjusted conversion price of approximately $21.00 per share of common stock. The conversion rate was adjusted to reflect the 1-for-6 reverse stock split effected on December 31, 2020 and is subject to additional adjustments in certain circumstances as described in the 2024 Indenture.

The Company may elect to settle conversions of the 2024 Notes in cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock. Holders who convert their 2024 Notes prior to June 1, 2023 (other than in connection with a make-whole fundamental change) will also be entitled to an interest make-whole payment equal to the sum of all regularly scheduled stated interest payments, if any, due on such 2024 Notes on each interest payment date occurring after the conversion date for such conversion and on or before June 1, 2023. In addition, the Company will have the right to cause all 2024 Notes then outstanding to be converted automatically if the volume-weighted average price per share of the Company’s common stock equals or exceeds 130% of the adjusted conversion price for a specified period of time and certain other conditions are satisfied.

Holders of the 2024 Notes will have the right, at their option, to require the Company to purchase their 2024 Notes if a fundamental change (as defined in the 2024 Indenture) occurs, such as a delisting of the Company’s common stock from the Nasdaq Global Select Market, in each case, at a repurchase price equal to 100% of the principal amount of the 2024 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. If a make-whole fundamental change occurs, as described in the 2024 Indenture, and a holder elects to convert its 2024 Notes in connection with such make-whole fundamental change, such holder may be entitled to an increase in the adjusted conversion rate as described in the 2024 Indenture.

Subject to a number of exceptions and qualifications, the 2024 Indenture restricts the ability of the Company and certain of its subsidiaries to, among other things, (i) pay dividends or make other payments or distributions on their capital stock, or purchase, redeem, defease or otherwise acquire or retire for value any capital stock, (ii) make certain investments, (iii) incur indebtedness or issue preferred stock, other than certain forms of permitted debt, which includes, among other items, indebtedness incurred to refinance the 2021 Notes, (iv) create liens on their assets, (v) sell their assets, (vi) enter into certain transactions with affiliates or (vii) merge, consolidate or sell of all or substantially all of their assets. The 2024 Indenture also requires the Company to make an offer to repurchase the 2024 Notes upon the occurrence of certain asset sales.

The 2024 Indenture provides that a number of events will constitute an event of default, including, among other things, (i) a failure to pay interest for 30 days, (ii) failure to pay the 2024 Notes when due at maturity, upon any required repurchase, upon declaration of acceleration or otherwise, (iii) failure to convert the 2024 Notes in accordance with the 2024 Indenture and the failure continues for five business days, (iv) not issuing certain notices required by the 2024 Indenture within a timely manner, (v) failure to comply with the other covenants or agreements in the 2024 Indenture for 60 days following the receipt of a notice of non-compliance, (vi) a default or other failure by the Company to make required payments under other indebtedness of the Company or certain subsidiaries having an outstanding principal amount of $30.0 million or more, (vii) failure by the Company or certain subsidiaries to pay final judgments aggregating in excess of $30.0 million, (viii) certain events of bankruptcy or insolvency and (ix) the commercial launch in the United States of a product determined by the U.S. FDA to be bioequivalent to Inbrija. In the case of an event of default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding 2024 Notes will become due and payable immediately without further action or notice. If any other event of default occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding 2024 Notes may declare all the notes to be due and payable immediately.

The Company determined that the exchange of the 2021 Notes for 2024 Notes qualified for a debt extinguishment and recognized a gain on extinguishment of $55.1 million for the year ended December 31, 2019, representing the difference between the fair value of the liability component immediately before the exchange and the carrying value of the debt. The Company recorded an adjustment of $38.4 million to additional paid-in capital to adjust the equity component of 2021 Notes in connection with the extinguishment.

The Company assessed all terms and features of the 2024 Notes in order to identify any potential embedded features that would require bifurcation. As part of this analysis, the Company assessed the economic characteristics and risks of the 2024 Notes, including the conversion, put and call features. The Company concluded the conversion features required bifurcation as a derivative. The fair value of the conversion features derivative was determined based on the difference between the fair value of the 2024 Notes with the conversion options and the fair value of the 2024 Notes without the conversion options using a binomial model. The Company determined that the fair value of the derivative upon issuance of the 2024 Notes was $59.4 million and recorded this amount as a derivative liability with an offsetting amount as a debt discount as a reduction to the carrying value of the 2024 Notes on the closing date, or December 24, 2019. There are several embedded features within the 2024 Notes which, upon issuance, did not meet the conditions for equity classification. As a result, these features were aggregated together and recorded as the derivative liability conversion option. The conversion feature is measured at fair value on a quarterly basis and the changes in the fair value of the conversion feature for the period will be recognized in the consolidated statements of operations.

The Company received stockholder approval on August 28, 2020 to increase the number of authorized shares of the Company’s common stock from 13,333,333 shares to 61,666,666 shares. As a result of the share approval, the Company determined that multiple embedded conversion options met the conditions for equity classification. The Company performed a valuation of these conversion options as of September 17, 2020, which was the date the Company completed certain securities registration obligations for the shares underlying the 2024 Notes. The resulting fair value of these conversion options was $18.3 million, which was reclassified to equity and presented in the statement of stockholder’s equity as of September 30, 2020, net of the $4.4 million tax impact. The equity component is not re-measured as long as it continues to meet the conditions for equity classification. The Company performed a valuation of the derivative liability related to certain embedded conversion features that are precluded from equity classification. The fair value of these conversion features was calculated to be negligible as of September 30, 2022.

The outstanding 2024 Note balances as of September 30, 2022 and December 31, 2021 consisted of the following:

(In thousands)	September 30, 2022			December 31, 2021
Liability component:
Principal		207,000		$	207,000
Less: debt discount and debt issuance costs, net		(44,240	)		(55,975	)
Net carrying amount	$	162,760		$	151,025

The Company determined that the expected life of the 2024 Notes was equal to the period through December 1, 2024 as this represents the point at which the 2024 Notes will mature unless earlier converted in accordance with their terms prior to such date. Accordingly, the total debt discount of $75.1 million, inclusive of the fair value of the embedded conversion feature derivative at issuance, is being amortized using the effective interest method through December 1, 2024. For the three- and nine-month periods ended September 30, 2022, the Company recognized $7.2 million and $21.1 million, respectively, of interest expense related to the 2024 Notes at the effective interest rate of 18.13%. The fair value of the Company’s 2024 Notes was approximately $157.3 million as of September 30, 2022.

In connection with the issuance of the 2024 Notes, the Company incurred approximately $5.7 million of debt issuance costs, which primarily consisted of underwriting, legal and other professional fees, and allocated these costs to the liability component and recorded as a reduction in the carrying amount of the debt liability on the balance sheet. The portion allocated to the 2024 Notes is amortized to interest expense over the expected life of the 2024 Notes using the effective interest method.

The following table sets forth total interest expense recognized related to the 2024 Notes for the three- and nine-month periods ended September 30, 2022 and 2021:

(In thousands)	Three-month period ended September 30, 2022		Three-month period ended September 30, 2021		Nine-month period ended September 30, 2022		Nine-month period ended September 30, 2021

On June 17, 2014, the Company issued $345 million aggregate principal amount of 1.75% Convertible Senior Notes due 2021 (the “2021 Notes”). On December 24, 2019, the Company completed the private exchange of $276.0 million aggregate principal amount of its then-outstanding 2021 Notes for a combination of newly issued 6.00% Convertible Senior Secured Notes due 2024 (the “2024 Notes”) and cash. The 2021 Notes received by the Company in the exchange were cancelled in accordance with their terms. Accordingly, upon completion of the exchange, $69.0 million of the 2021 Notes remained outstanding. On June 15, 2021, the Company repaid the outstanding balance of the 2021 Notes at their maturity date using cash on hand.

In accounting for the issuance of the 2021 Notes, the Company separated the 2021 Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the 2021 Notes as a whole. The equity component is not re-measured as long as it continues to meet the conditions for equity classification.

In connection with the issuance of the 2021 Notes, the Company incurred approximately $7.5 million of debt issuance costs, which primarily consisted of underwriting, legal and other professional fees, and allocated these costs to the liability and equity components based on the allocation of the proceeds. Of the total $7.5 million of debt issuance costs, $1.3 million were allocated to the equity component and recorded as a reduction to additional paid-in capital and $6.2 million were allocated to the liability component and recorded as a reduction in the carrying amount of the debt liability on the balance

sheet. The portion allocated to the liability component is amortized to interest expense over the expected life of the 2021 Notes using the effective interest method. The Company wrote off $1.2 million of issuance cost associated with the exchange of the 2021 Notes.

The following table sets forth total interest expense recognized related to the 2021 Notes for the three- and nine-month periods ended September 30, 2022 and 2021:

(In thousands)	Three-month period ended September 30, 2022		Three-month period ended September 30, 2021		Nine-month period ended September 30, 2022		Nine-month period ended September 30, 2021

Our Biotie subsidiary received fourteen non-convertible capital loans granted by Business Finland (formerly Tekes) for research and development of specific drug candidates, with an aggregate adjusted acquisition-date fair value of $20.5 million (€18.2 million) and an aggregate carrying value of $24.9 million as of September 30, 2022. The loans are to be repaid only when the consolidated retained earnings of Biotie from the development of specific loan-funded product candidates is sufficient to fully repay the loans. In light of the status of the loan-funded product candidates, we filed an application with Business Finland for waiver of the loans and accrued interest. In July 2022, Business Finland granted these waivers, which will become effective upon Biotie’s compliance with specified conditions to be completed, including a residual payment of approximately $50,000 for one of the loans. As of September 30, 2022, Biotie had approximately $14.5 million in cash.
