Notes to Unaudited Consolidated Financial Statements

1. Organization

We are a global, commercial-stage biopharmaceutical company focused on the development and commercialization of therapies for rare diseases with significant unmet needs.

Our first commercial product is Keveyis (dichlorphenamide), the first and only treatment approved by the U.S. Food and Drug Administration (the “FDA”) for hyperkalemic, hypokalemic, and related variants of primary periodic paralysis (“PPP”), a group of rare hereditary disorders that cause episodes of muscle weakness or paralysis.

We have two clinical-stage product candidates for rare endocrine diseases, Recorlev and veldoreotide. Recorlev (levoketoconazole), the pure 2S,4R enantiomer of the enantiomeric pair comprising ketoconazole, is a next-generation steroidogenesis inhibitor being investigated as a chronic therapy for adults with endogenous Cushing’s syndrome. Veldoreotide is a next-generation somatostatin analog being investigated for potential applications in conditions amenable to somatostatin receptor activation. Both levoketoconazole and veldoreotide have received orphan designation from the FDA and the European Medicines Agency (“EMA”)

Liquidity

We believe that our cash and cash equivalents of $63.8 million at June 30, 2021, will be sufficient to allow us to fund planned operations for at least 12 months beyond the issuance date of these unaudited consolidated financial statements.

We may never achieve profitability, and unless and until we do, we will continue to need to raise additional capital. We plan to continue to fund our operations and capital funding needs through equity or debt financing along with revenues from Keveyis. There can be no assurances, however, that additional funding will be available on terms acceptable to us.

Transaction Agreement with Xeris Pharmaceuticals, Inc.

On May 24, 2021, we announced that we had signed an agreement to be acquired by Xeris Pharmaceuticals, Inc. (“Xeris”). Upon close of the transaction, the businesses of Xeris and Strongbridge Biopharma plc (“Strongbridge”) will be combined under a new entity to be called Xeris Biopharma Holdings, Inc The agreement, including the maximum aggregate amount payable under the contingent value rights (the “CVRs”), values Strongbridge at approximately $267 million based on the closing price of Xeris common stock of $3.47 on May 21, 2021, and Strongbridge’s fully diluted share capital.

Under the terms of the agreement, at closing, Strongbridge shareholders will receive a fixed exchange ratio of 0.7840 shares of Xeris Biopharma Holdings common stock for each Strongbridge ordinary share they own. Based on the closing price of Xeris common stock on May 21, 2021, this represents approximately $2.72 per Strongbridge ordinary share and a 12.9% premium to the closing price of Strongbridge ordinary shares on May 21, 2021. Strongbridge shareholders will also receive 1 non-tradeable CVR for each Strongbridge ordinary share they own, worth up to an additional $1.00 payable in cash or Xeris Biopharma Holdings common stock, or a combination of cash and additional Xeris Biopharma Holdings common stock (at Xeris Biopharma Holdings’ sole election) upon achievement of the following milestones: (i) $0.25 per CVR upon the first listing of at least one issued patent for Keveyis in the U.S. Food and Drug Administration’s Orange Book by the end of 2023 or the first achievement of at least $40 million in Keveyis annual net sales in 2023, (ii) $0.25 per CVR upon the first achievement of at least $40 million in Recorlev annual net sales in 2023, and (iii) $0.50 per CVR upon the first achievement of at least $80 million in Recorlev annual net sales in 2024. The minimum payment on the CVR per Strongbridge ordinary share is zero and the maximum payment is $1.00 in cash or Xeris Biopharma Holdings common stock, or a combination of cash and

additional Xeris Biopharma Holdings common stock at Xeris Biopharma Holdings’ sole election. The transaction is expected to close early in the fourth quarter of 2021, subject to the satisfaction of closing conditions.

The transaction, which has been unanimously approved by the boards of directors of both companies is expected to close early in the fourth quarter of 2021, subject to the satisfaction of closing conditions. Upon close of the transaction, the current Xeris stockholders are expected to own approximately 60% of the combined company, while current Strongbridge shareholders are expected to own approximately 40%.

On July 2, 2021, Xeris Biopharma Holdings filed with the SEC a registration statement on Form S-4, to register the Xeris Biopharma Holdings common stock to be issued in connection with the transaction, which also constitutes the joint proxy statement of Strongbridge and Xeris under Section 14(a) of the Securities Exchange Act of 1934. Upon the effectiveness of the Form S-4, we intend to solicit shareholders for their approval of the merger with Xeris.

In connection with this transaction, we have incurred, and will continue to incur, transaction-related costs. A portion of those costs are contingent on the transaction closing, such as investment banking fees, and employee related costs. For the six months ended June 30, 2021, we have incurred $5.8 million of expenses, which are recorded in our selling, general and administrative expense within the Consolidated Statements of Operations and Comprehensive Loss.

In addition, all of our outstanding restricted stock units will vest immediately prior to the closing of this transaction, and all of our outstanding stock options will vest immediately prior to the closing of this transaction and be converted into options to purchase Xeris Biopharma Holdings common stock.

2. Summary of significant accounting policies and basis of presentation

Basis of presentation

These unaudited consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The unaudited consolidated financial statements reflect all adjustments, which include only normal recurring adjustments that are, in the opinion of management, necessary to present a fair statement of the operating results and financial position for the periods presented.

The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts and disclosures in the consolidated financial statements. Actual results could differ from those estimates. Results for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

These unaudited consolidated financial statements should be read in conjunction with the accounting policies and notes to the audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the U.S. Securities and Exchange Commission on March 3, 2021 (the “2020 Annual Report”). Our significant accounting policies are described in Note 2 of the notes to the audited consolidated financial statements included in our 2020 Annual Report. Since the date of those financial statements, there have been no changes to our significant accounting policies.

Leases

We account for leases in accordance with Accounting Standards Codification Topic 842, Leases (“ASC 842”). We determine if an arrangement is a lease at contract inception. A lease exists when a contract conveys to us the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: (1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment), and (2) we have the right to control the use of the identified asset.

Table of Contents

Operating leases where we are the lessee are included in Right of use (“ROU”) assets and Accrued and other current liabilities and Other long-term liabilities on our Consolidated Balance Sheets. The lease liabilities are initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date.

Key estimates and judgments include how we determined (1) the discount rate we use to discount the unpaid lease payments to present value, (2) lease term and (3) lease payments.

ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Because our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Our incremental borrowing rate for a lease is the rate of interest we would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The lease term for all of our leases includes the noncancellable period of the lease. Lease payments included in the measurement of the lease asset or liability are comprised of our fixed payments.

The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date less any lease incentives received.

For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus (minus) any prepaid (accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We monitor for events or changes in circumstances that require a reassessment of a lease. If a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in profit or loss.

We have elected not to recognize ROU assets and lease liabilities for all short-term leases that have a lease term of 12 months or less. We recognize the lease payments associated with our short-term leases as an expense on a straight-line basis over the lease term. Variable lease payments associated with these leases are recognized and presented in the same manner as for all of our other leases.

Cash, cash equivalents and marketable securities

We consider all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents consist of account balances at banks and money market accounts, respectively.

We occasionally invest our excess cash balances in marketable debt securities of highly rated financial institutions. We seek to diversify our investments and limit the amount of investment concentrations for individual institutions, maturities and investment types. We classify marketable debt securities as available-for-sale and, accordingly, record such securities at fair value. We classify these securities as current assets as these investments are available to us for use in funding current operations. There were no marketable securities as of June 30, 2021 or December 31, 2020.

Unrealized gains and losses on marketable debt securities are recorded as a separate component of Accumulated other comprehensive income (loss) included in shareholders’ equity.

Table of Contents

Segment information

Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. We view our operations and manage our business in one operating segment.

Net loss per share

Basic net loss per share is calculated by dividing the net loss attributable to shareholders by the weighted average number of ordinary shares outstanding during the period. Diluted net loss per share is calculated by dividing the net loss attributable to shareholders by the weighted-average number of ordinary shares outstanding for the period, including any dilutive effect from outstanding stock options or other equity-based instruments. Shares used in the diluted net loss per share calculations exclude anti-dilutive ordinary share equivalents, which currently consist of outstanding stock options, unvested restricted stock units (“RSUs”), equity-classified warrants and the conversion feature of our outstanding term loan agreement.

The following potentially dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding for the six months ending June 30, 2021 and 2020, as they would be anti-dilutive:

Recent accounting pronouncements – not yet adopted

June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires an entity to measure and recognize expected credit losses for certain financial instruments, including trade receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities with unrealized losses, the standard requires allowances to be recorded through net income instead of directly reducing the amortized cost of the investment under the current other-than-temporary impairment model. For smaller reporting companies, the standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022.

3. Revenue recognition

Product sales, net

We sell Keveyis to one specialty pharmacy provider (the “Customer”), who is the exclusive distributor of Keveyis in the United States. The Customer subsequently resells Keveyis to patients, most of whom are covered by payors that may provide for government-mandated or privately negotiated rebates with respect to the purchase of Keveyis.

Revenues from sales of Keveyis are recognized when we satisfy a performance obligation by transferring control of the product to the Customer. Transfer of control occurs upon receipt of the product by the Customer. We expense incremental costs related to the set-up of contracts with the Customer when incurred, as these costs do not meet the criteria for capitalization.

Table of Contents

Reserves for variable consideration

Revenues from sales of Keveyis are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established and that result from rebates, co-pay assistance and other allowances that are offered between us and the patients’ payors. There is no variable consideration reserve for returns as we do not accept returns of Keveyis. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (if the amount is payable to the Customer) or a current liability (if the amount is payable to a party other than the Customer). Where appropriate, these estimates may take into consideration a range of possible outcomes that are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted buying and payment patterns of the Customer. Overall, these reserves reflect our best estimates of the amount of consideration to which we are entitled based on the terms of the contract. The amount of variable consideration that is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from our estimates. We reassess our estimates on an ongoing basis. If actual results in the future vary from our estimates, we will adjust our estimates. Any such adjustments would affect net product revenue and earnings in the period such variances become known.

Trade Discount: We provide the Customer with a discount that is explicitly stated in our contract and is recorded as a reduction of revenue in the period the related product revenue is recognized. In addition, we receive sales order management, data and distribution services from the Customer. To the extent the services received are distinct from our sale of Keveyis to the Customer, these payments are classified in selling, general and administrative expenses in our consolidated statement of operations and comprehensive loss.

Funded Co-pay Assistance Program: We contract with a third-party to manage the co-pay assistance program intended to provide financial assistance to qualified insured patients. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with Keveyis that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. These payments are consideration payable to the Customer and the related reserve is recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses on the consolidated balance sheet.

Government Rebates: We are subject to discount obligations under state Medicaid programs and Medicare. We estimate our Medicaid and Medicare rebates for the estimated patient mix. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability, which is included in accrued expenses on the consolidated balance sheet. For Medicaid, accruals are based on estimates of future Medicaid beneficiary utilization applied to the Medicaid unit rebate formula established by the Center for Medicaid and Medicare Services. Manufacturers of pharmaceutical products are responsible for 70% of the patient’s cost of branded prescription drugs related to the Medicare Part D Coverage Gap. In order to estimate the cost to us of this Medicare coverage gap responsibility, we estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program. Our liability for these rebates consists of estimates of claims for the current quarter and estimated future claims that will be made for Keveyis transactions that have been recognized as revenue but remain in the Customer’s inventory at the end of each reporting period.

Temporary Supply and Patient Assistance Programs: We provide free Keveyis to uninsured patients who satisfy pre-established criteria for either the Temporary Supply Program or the Patient Assistance Program. Patients who meet the Temporary Supply Program eligibility criteria may receive a temporary supply of free Keveyis for no more than 60 days while there is a determination of the patient’s third-party insurance, prescription drug benefit or other third-party coverage for Keveyis. The Patient Assistance Program provides free Keveyis for up to 12 months to uninsured patients who satisfy pre-established criteria for financial need. We do not recognize any revenue related to these free products and the associated costs are classified in selling, general and administrative expenses in our consolidated statements of operations and comprehensive loss.

4. Fair value measurements

We record financial assets and liabilities at fair value. Because of their short-term nature, the amounts reported in the balance sheet for cash, accounts receivable and accounts payable approximate fair value.

The guidance requires fair value measurements to maximize the use of “observable inputs.” The three-level hierarchy of inputs to measure fair value are as follows:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Because of their short-term nature, the amounts reported in the balance sheet for cash and accounts payable approximate fair value.

Level 2: Significant observable inputs other than Level 1 prices such as quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The fair values of the outstanding warrants were measured using the Black-Scholes option-pricing model. Inputs used to determine estimated fair value of the warrant liabilities include the estimated term of the warrants, risk-free interest rates, and the expected volatility of the underlying stock. The significant unobservable inputs used in the fair value measurement of the warrant liabilities were the volatility rate and the estimated term of the warrants. Generally, increases and decreases in the fair value of the underlying stock and estimated term would result in a directionally similar impact to the fair value measurement.

We did not have any transfers between the different levels.

The following table presents our assets and liabilities that are measured at fair value on a recurring basis for the periods presented (in thousands):

5. Intangible asset and goodwill

The following represents the balance of our intangible asset and goodwill as follows (in thousands):


	As of June 30, 2021
	Beginning of Period		Amortization		End of Period
Keveyis	$	20,088	$	(2,511)	$	17,577
Goodwill		7,256		—		7,256
Total	$	27,344	$	(2,511)	$	24,833

Our finite-lived intangible asset consists of acquired developed product rights obtained from our acquisition of Keveyis (dichlorphenamide) from a subsidiary of Taro Pharmaceutical Industries Ltd. (“Taro”).

Pursuant to the terms of the Asset Purchase Agreement and Supply Agreement that we entered into with Taro in December 2016, we paid Taro an upfront payment in two installments of $1 million in December 2016 and $7.5 million in March 2017, and will pay an aggregate of $7.5 million in potential milestone payments upon the achievement of certain product sales targets. Taro has agreed to continue to manufacture Keveyis for us under an exclusive supply agreement through the orphan exclusivity period. We are obligated to purchase from Taro certain annual minimum amounts of product totaling approximately $29 million over a six-year period. We have concluded that the supply price payable by us exceeds fair value and, therefore, have used a discounted cash flow method with a probability assumption to value the payments in excess of fair value at $29.3 million, for which we have recorded an intangible asset and corresponding liability. This liability is being reduced as we purchase inventory over the term of the Supply Agreement that we entered into with Taro. In addition, we incurred transaction costs of $2.4 million. The transaction resulted in the recording of an intangible asset of $40.2 million. This asset is being amortized over an eight-year period using the straight-line method.

We recorded amortization expense of $1.3 million and $2.5 million for the three and six months ended June 30, 2021, and 2020.

6. Long-term debt

On May 19, 2020, we entered into a $30 million Term Loan Agreement (the “Loan Agreement”) with Avenue Venture Opportunities Fund L.P. (“Avenue”), as administrative agent and collateral agent, and the lenders named therein and from time to time a party thereto (the “Lenders”). Pursuant to the terms of the Loan Agreement, our wholly-owned subsidiary, Strongbridge U.S. Inc. (the “Borrower”) borrowed $10 million (the “Initial Loan”) from the Lenders at closing. As a result of achieving positive top-line data for Recorlev in our Phase 3 LOGICS clinical trial in September 2020, we borrowed an additional $10 million under the Loan Agreement (the “Second Loan”) on December 30, 2020. The remaining $10 million tranche (the “Third Loan”) will become available to us between October 1, 2021 and March 31, 2022 if we achieve FDA approval of Recorlev and subject to Avenue’s investment committee approval.

The Loan Agreement has a four-year term, no minimum revenue or cash balance financial covenants and an interest-only period for 24 months that can increase to 36 months assuming we receive FDA approval of Recorlev. Amounts borrowed under the Loan Agreement accrue interest at a floating rate per annum (based on a year of 365 days) equal to the sum of (a) the greater of (x) the Prime Rate reported in The Wall Street Journal on the last business day of the month that immediately precedes the month in which the interest will accrue, and (y) 3.25%, plus (b) 6.75%. The interest rate as of June 30, 2021 was 10%.

We paid a commitment fee of $200,000 (1% of the amounts of the Initial Loan and the Second Loan) at closing. We are also required to pay the Lenders a final payment fee upon repayment or prepayment of any loans made under the Loan Agreement in accordance with the terms and conditions of the Loan Agreement.

Under the terms of the Loan Agreement, we may prepay all or a portion of the outstanding principal amount of any loans outstanding under the Loan Agreement at any time upon prior notice to the Lenders subject to a prepayment

premium (which reduces after the first year) and the payment of the pro rata portion of the final payment fee (to the extent not already paid) based on the amount of loans being prepaid. In certain circumstances, including a change of control and certain asset sales or licensing transactions, we may be required to prepay all or a portion of loans outstanding, and, to the extent required under the terms of the Loan Agreement, the applicable prepayment premium and final payment fee.

As security for our obligations under the Loan Agreement, we entered into a security agreement with Avenue, pursuant to which we granted a lien on substantially all of our assets, including intellectual property, to the Secured Parties (as such term is defined in the Loan Agreement).

Avenue has the right to convert up to $3 million of the aggregate principal amount of any loans outstanding under the Loan Agreement into ordinary shares at a price per share of $2.24. We have accounted for this term as a beneficial conversion feature, and the fair value is recorded in Additional paid-in capital. This amount is recorded as a debt discount and classified as a contra-liability on the consolidated balance sheet and amortized to interest expense over the term of the loan.

In connection with the execution of both the Loan Agreement and the Second Loan, we issued to Avenue warrants to purchase up to an aggregate of 267,390 ordinary shares at an exercise price (the “Exercise Price”) of $1.87 (which is equal to the five-day volume weighted average price as of the trading day immediately prior to execution of the financing agreement) for each of the tranches of debt, respectively. The warrants are exercisable, in full or in part, at any time prior to five years following the issue date for both tranches of the loan. We have accounted for these warrants as equity, and the fair value is recorded into Additional paid-in capital. This amount is recorded as a debt discount and classified as a contra-liability on the consolidated balance sheet and amortized to interest expense over the term of the loan. If we borrow the Third Loan, we will be required to issue to the Lenders or their designees additional warrants to purchase ordinary shares equal to an aggregate of 5% of the Third Loan divided by the Exercise Price, rounded down to the nearest whole share.

Loan Amendment

On July 23, 2021, Strongbridge, the Borrower and Avenue entered into an amendment (the “Loan Amendment”) to the Loan Agreement.

Under the Term Loan Agreement, Strongbridge granted to Avenue an option to convert up to $3 million of the aggregate principal amount of any loans outstanding under the Loan Agreement into Strongbridge ordinary shares (the “Conversion Option”). The Loan Amendment amends the Conversion Option such that $10 million of the aggregate principal amount of any loans outstanding under the Loan Agreement will automatically convert into Strongbridge ordinary shares immediately prior to the completion of the acquisition of Strongbridge by Xeris Pharmaceuticals, Inc. The conversion price remains unchanged at $2.24 per share.

Future principal payments due under the Loan Agreement, if the interest payment only period is not extended beyond the current 24-month period, are as follows (in thousands):

8. Commitments and contingencies

(a) Commitments to Taro Pharmaceuticals Industries Ltd.

As of June 30, 2021, our remaining obligation under the Supply Agreement (see Note 5) was $14.1 million. The agreement with Taro may extend beyond the orphan exclusivity period unless terminated by either party pursuant to the terms of the agreement. If terminated by Taro at the conclusion of the orphan exclusivity period, we have the right to manufacture the product on our own or have the product manufactured by a third party on our behalf. We are also required to reimburse Taro for its royalty obligation resulting from its sale of Keveyis to us.

(b) Indemnifications

In the ordinary course of business and in connection with the sale of assets and businesses and other transactions, we often agree to indemnify our counterparties against certain liabilities that may arise in connection with a transaction or that are related to events and activities prior to or following a transaction, such as breaches of contracts, unfavorable tax consequences and employee liabilities. If a counterparty were to make a successful indemnification claim against us, we may be required to reimburse the loss and such amount could be material to our consolidated financial statements. Where appropriate, the obligation for such indemnifications is recorded as a liability. Because these agreements generally do not specify the maximum amount of indemnification a counterparty may be entitled to, the overall maximum amount of our potential indemnification liability under these agreements cannot be reasonably estimated. However, we believe that the likelihood of a material liability being triggered under these indemnification obligations is not probable at this time.

9. Taxes

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts and tax bases of assets and liabilities and operating loss carryforwards and other attributes using enacted rates expected to be in effect when those differences reverse. Valuation allowances are provided against deferred tax assets that are not more likely than not to be realized.

We assess our ability to realize deferred tax assets. Changes in future earnings projections, among other factors, may cause us to adjust our valuation allowance on deferred tax assets. Any such adjustments would impact our income tax expense in the period in which it is determined that these factors have changed.

Table of Contents

We recorded income tax expense of $1,000 for the three and six months ended June 30, 2021 and did not record an expense for the three and six months ended June 30, 2020.

10. Ordinary Shares

Equity transactions

We entered into an equity distribution agreement with JMP Securities LLC (“JMP”) on April 28, 2017, pursuant to which we could sell, at our option, from time to time, up to an aggregate of $40 million of our ordinary shares through JMP, as sales agent. The agreement provided for a commission to JMP equal to 3% of the gross proceeds from the sale of our ordinary shares under this at-the-market (“ATM”) facility. Pursuant to the terms of the equity distribution agreement, we reimbursed JMP for certain out-of-pocket expenses, including the fees and disbursements of counsel to JMP, incurred in connection with establishing the ATM facility and provided JMP with customary indemnification rights. During the three months ended March 31, 2021, we sold an aggregate of 11,311 ordinary shares under the ATM facility at an average selling price of $3.36 per share, resulting in net proceeds of approximately $38,000 after payment of fees to JMP of $1,100. This equity distribution agreement was terminated on March 24, 2021.

We entered into an equity distribution agreement with Jefferies LLC (“Jefferies”) on March 25, 2021, pursuant to which we may sell, at our option, from time to time, up to an aggregate of $50 million of our ordinary shares through Jefferies, as sales agent. We will pay Jefferies a commission equal to 3% of the gross proceeds from the sale of our ordinary shares under the ATM facility. Pursuant to the terms of the equity distribution agreement, we reimbursed Jefferies for certain out-of-pocket expenses, including the fees and disbursements of counsel to Jefferies, incurred in connection with establishing the ATM facility and have provided Jefferies with customary indemnification rights. For the period ended June 30, 2021, we did not sell any shares under this agreement.

11. Stock-based compensation

Our board of directors has adopted the 2017 Inducement Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of equity-based awards to new employees. The purpose of the Inducement Plan is to attract valued employees by offering them a greater stake in our success and a closer identity with us, and to encourage ownership of our ordinary shares by such employees. The Inducement Plan became effective on February 23, 2017. As of June 30, 2021, 1,297,353 shares are available for issuance pursuant to the Inducement Plan.

Table of Contents

Our board of directors has adopted, and our shareholders have approved, the 2015 Equity Compensation Plan (the “2015 Plan”). The 2015 Plan provides for the grant of incentive stock options to our employees and any parent or subsidiary corporation’s employees, and for the grant of nonstatutory stock options, stock awards, and RSUs to our employees, directors and consultants and our parent or subsidiary corporations’ employees and consultants. The 2015 Plan became effective on September 3, 2015. As of June 30, 2021, 2,531,458 shares are available for issuance pursuant to the 2015 Plan.

Our board of directors has adopted, and our shareholders have approved, the Non-Employee Director Equity Compensation Plan (the “Non-Employee Director Plan”). The Non-Employee Director Plan provides for the grant of nonstatutory stock options, stock awards, and RSUs to our non-employee directors. The Non-Employee Director Plan became effective on September 3, 2015. As of June 30, 2021, 207,247 shares are available for issuance pursuant to the Non-Employee Director Plan.

A summary of our outstanding stock options as of June 30, 2021, is as follows:

The weighted average grant date fair value of stock options granted during the six months ended June 30, 2021 and 2020 was $2.16 and $2.00, respectively.

Restricted stock units

We grant RSUs to employees and to members of our board of directors. RSUs that are granted to employees vest one, two or three years from the date of issuance, provided that the employee is employed by us on such vesting date. RSUs that are granted to directors’ vest on the one-year anniversary of the grant date, provided that the director continues to serve as a member of the board of directors continuously from the grant date through such one-year anniversary. All RSUs will fully vest upon a change of control of our company. If and when the RSUs vest, we will issue one ordinary share for each whole RSU that has vested, subject to satisfaction of the employee’s or director’s tax withholding obligations. The RSUs will cease to be outstanding upon the issuance of ordinary shares upon vesting. We recorded expense related to RSUs, which is included in the stock-based compensation table below, of $2.8 million and $1 million for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, the total unrecognized compensation expense related to unvested RSUs is $5.8 million, which we expect to recognize over an estimated weighted-average period of 1.37 years.

As of June 30, 2021, the total unrecognized compensation expense related to unvested stock options is $5.3 million, which we expect to recognize over an estimated weighted-average period of 1.94 years.

In determining the estimated fair value of our service-based awards, we use the Black-Scholes option-pricing model and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment.

Recent Developments

Transaction Agreement with Xeris Pharmaceuticals, Inc.

On May 24, 2021, we announced that we had signed an agreement to be acquired by Xeris. Upon close of the transaction, the businesses of Xeris and Strongbridge will be combined under a new entity to be called Xeris Biopharma Holdings, Inc. The agreement, including the maximum aggregate amount payable under the CVRs, values Strongbridge at approximately $267 million based on the closing price of Xeris common stock of $3.47 on May 21, 2021, and Strongbridge’s fully diluted share capital.

Under the terms of the agreement, at closing, Strongbridge shareholders will receive a fixed exchange ratio of 0.7840 shares of Xeris Biopharma Holdings common stock for each Strongbridge ordinary share they own. Based on the closing price of Xeris common stock on May 21, 2021, this represents approximately $2.72 per Strongbridge ordinary share and a 12.9% premium to the closing price of Strongbridge ordinary shares on May 21, 2021. Strongbridge shareholders will also receive 1 non-tradeable CVR for each Strongbridge ordinary share they own, worth up to an additional $1.00 payable in cash or Xeris Biopharma Holdings common stock, or a combination of cash and additional Xeris Biopharma Holdings common stock (at Xeris Biopharma Holdings’ sole election) upon achievement of the following milestones: (i) $0.25 per CVR upon the first listing of at least one issued patent for Keveyis in the U.S. Food & Drug Administration’s Orange Book by the end of 2023 or the first achievement of at least $40 million in Keveyis annual net sales in 2023, (ii) $0.25 per CVR upon the first achievement of at least $40 million in Recorlev annual net sales in 2023, and (iii) $0.50 per CVR upon the first achievement of at least $80 million in Recorlev annual net sales in 2024. The minimum payment on the CVR per Strongbridge ordinary share is zero and the maximum payment is $1.00 in cash or Xeris Biopharma Holdings common stock, or a combination of cash and additional Xeris Biopharma Holdings common stock at Xeris Biopharma Holdings’ sole election. The transaction is expected to close early in the fourth quarter of 2021, subject to the satisfaction of closing conditions.

In connection with this transaction, we have incurred, and will continue to incur, transaction-related costs. For the six months ended June 30, 2021, we have incurred $5.8 million of expenses, which are recorded in our selling, general and administrative expense within the Consolidated Statements of Operations and Comprehensive Loss. In addition, all of our outstanding restricted stock units will vest immediately prior to the closing of this transaction, and all of our outstanding stock options will vest immediately prior to the closing of this transaction and be converted into options to purchase Xeris Biopharma Holdings common stock.

Intellectual Property and Regulatory Developments

On June 3, 2021, The United States Patent and Trademark Office (USPTO) has issued to Strongbridge for Recorlev U.S. Patent No. 11,020,393 entitled, “Methods of Treating Disease with Levoketoconazole” which covers a method of treating Cushing’s syndrome patients with RECORLEV® (levoketoconazole) who also take metformin for Type 2 diabetes. The term of the U.S. patent will expire on March 2, 2040.

On May 12, 2021, we received the official Day 74 letter from the FDA for Recorlev. Within the Day 74 letter, the FDA set a Prescription Drug User Fee Act (PDUFA) target action date of January 1, 2022, which reflects a projected 10-month standard review period.

Loan Amendment

On July 23, 2021, Strongbridge , its subsidiary, Strongbridge U.S. Inc., and Avenue Venture Opportunities Fund, L.P. (“Avenue”) entered into an amendment (the “Loan Amendment”) to the Term Loan Agreement, dated May 19, 2020 (the “Loan Agreement”), among Strongbridge, certain of its subsidiaries and Avenue.

Under the Loan Agreement, Strongbridge granted to Avenue an option to convert up to $3 million of the aggregate principal amount of any loans outstanding under the Loan Agreement into Strongbridge ordinary shares (the “Conversion Option”). The Loan Amendment amends the Conversion Option such that $10 million of the aggregate

Table of Contents

principal amount of any loans outstanding under the Loan Agreement will automatically convert into Strongbridge ordinary shares immediately prior to the completion of the acquisition of Strongbridge by Xeris Pharmaceuticals, Inc. The conversion price remains unchanged at $2.24 per share.

COVID-19 (and related variants)

On March 11, 2020, the World Health Organization declared COVID-19 a pandemic, and on March 13, 2020, the United States declared a national emergency with respect to COVID-19. The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, and created significant volatility and disruption in the financial markets. Although we are seeing the number of COVID-19 cases decline in certain regions, other regions are experiencing a resurgence of COVID-19 cases. In addition, the emergence of COVID-19 variants, the variable and gradual process of vaccine distribution in some countries, and the concern over further waves of infections are causing continued unpredictability and uncertainty.

While the COVID-19 pandemic did not have a material impact on our business, financial condition, or results of operations for the six months ended June 30, 2021, we have experienced operational business disruptions as a result of the pandemic. For example, most of our corporate employees are currently working remotely from home, and we did suspend all commercial air and train travel for business for a period of time. In addition, our field teams have had limited access to physicians. As of June 1, 2021, we allowed commercial air and train travel for business and as of July 1, 2021, we have re-opened the office for those employees who choose to work from the office.

We continue to monitor the impacts of COVID-19 (including the new COVID-19 variants) on the global economy and on our business operations. However, at this time, it is difficult to predict how long the potential operational impacts of the pandemic will last or to what degree further disruption might impact our operations and financial results. An extended period of global supply chain and economic disruption could materially affect our business, results of operations, access to sources of liquidity and financial condition, as well as our ability to execute our business strategies and initiatives in their respective expected time frames.

Financial Operations Overview

The following discussion sets forth certain components of our statements of operations as well as factors that impact those items.

Product Sales, net

We sell Keveyis to one specialty pharmacy provider (the “Customer”), who is the exclusive specialty pharmacy for Keveyis in the United States. The Customer subsequently dispenses Keveyis to patients, most of whom are covered by payors that may provide for government-mandated or privately negotiated rebates with respect to the purchase of Keveyis. Revenues from sales of Keveyis are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established and that result from rebates, co-pay assistance and other allowances that are offered by us and the patients’ payors.

Cost of Sales

Cost of sales includes third-party acquisition costs, third-party warehousing and product distribution charges.

Selling, General and Administrative Expenses

Selling, general and administrative expenses include personnel costs, costs for outside professional services and other allocated expenses. Personnel costs consist of salaries, bonuses, benefits, travel and stock-based compensation. Outside professional services consist of legal, accounting and audit services, commercial evaluation and strategy services, sales, market access, marketing, investor relations, public relations, recruiting and other consulting services.

Table of Contents

Research and Development Expenses

We expense all research and development costs as incurred. Our research and development expenses consist primarily of costs incurred in connection with the development of our product candidates, including:

●

personnel-related costs, such as salaries, bonuses, benefits, travel and other related expenses, including stock-based compensation;

●

expenses incurred under our agreements with contract research organizations (CROs), clinical sites, contract laboratories, medical institutions and consultants that plan and conduct our preclinical studies and clinical trials. We recognize costs for each grant project, preclinical study or clinical trial that we conduct based on our evaluation of the progress to completion, including the use of information and data provided to us by our external research and development vendors and clinical sites;

●

costs associated with regulatory filings; and

●

costs of acquiring preclinical study and clinical trial materials, and costs associated with formulation, process development and statistical analysis.

We do not allocate personnel-related research and development costs, including stock-based compensation or other indirect costs, to specific programs, as they are deployed across multiple projects under development.

We do track our external research and development cost by project, and currently over 99% of the costs are related to our development of Recorlev.

Amortization of Intangible Asset

Amortization of intangible asset relates to the amortization of our product rights to Keveyis. This intangible asset is being amortized over an eight-year period using the straight-line method.

Interest Expense

Interest expense represents interest paid to our lender, amortization of our debt discount, and issuance costs associated with loan and security agreements.

Other Expense, Net

Other expense, net, consists of unrealized loss or gain on the remeasurement of the fair value of the warrant liability, interest income generated from our cash, cash equivalents and marketable securities, foreign exchange gains and losses and gains and losses on investments.

Critical Accounting Policies and Significant Judgments and Estimates

This management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe there have been no significant changes in our critical accounting policies and significant judgments and estimates as discussed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2020 Annual Report.

Revenues and cost of sales

Net product sales were $10.0 million for the three months ended June 30, 2021, an increase of $2.3 million compared to the three months ended June 30, 2020. Product sales from Keveyis increased primarily due to an increase in the number of patients on Keveyis and an increase in the price of Keveyis. Of the total increase in product sales, $1.9 million was due to the increase in the number of patients on Keveyis and $0.8 million from an increase in the price of Keveyis, which were offset by an increase of $0.4 million in our sales allowances. Cost of sales increased due to the increase in sales volume for the three months ended June 30, 2021.

Net product sales were $18.4 million for the six months ended June 30, 2021, an increase of $4.0 million compared to the six months ended June 30, 2020. Product sales from Keveyis increased primarily due to an increase in the number of patients on Keveyis and an increase in the price of Keveyis. Of the total increase in product sales, $2.9 million was due to the increase in the number of patients on Keveyis and $1.4 million from an increase in the price of Keveyis, which were offset by an increase of $0.3 million in our sales allowances. Cost of sales decreased due to changes in the assumptions underlying our purchase forecast which affects the allocation of cost between the purchase price of our inventory and the supply agreement. As a result of our ongoing efforts to evaluate and update our sales forecast for Keveyis based on actual sales, we reduced our inventory purchase forecast to better align with this updated sales forecast and inventory on-hand. This adjustment to the purchase forecast has resulted in a lower amount of the cost of each inventory batch being allocated to inventory and correspondingly a higher amount of the cost of each inventory batch being allocated to reduce the supply agreement liability. As a result of the reduction in the allocated cost to inventory, our cost of sales has correspondingly decreased on a per unit level.

Selling, general and administrative expenses were $16.0 million for the three months ended June 30, 2021, an increase of $6.4 million compared to the three months ended June 30, 2020. The increase is primarily due to an increase in compensation costs and an increase in our outside professional fees, mostly due to investment banking fees and legal expenses related to our proposed business combination transaction with Xeris.

Selling, general and administrative expenses were $26.9 million for the six months ended June 30, 2021, an increase of $6.9 million compared to the six months ended June 30, 2020. The increase is primarily due to an increase in compensation costs and an increase in our outside professional fees, mostly due to investment banking fees and legal expenses related to our proposed business combination transaction with Xeris.

Research and Development Expenses

The following table summarizes our research and development expenses during the three and six months ended June 30, 2021 and 2020:


	Three Months Ended						Six Months Ended
	June 30,				Change		June 30,				Change
	2021		2020		$		2021		2020		$

Total research and development expenses	$	5,397	$	6,152	$	(755)	$	11,235	$	13,704	$	(2,469)

Research and development expenses were $5.4 million for the three months ended June 30, 2021, a decrease of $0.8 million compared to the three months ended June 30, 2020. The decrease was primarily due to decreases in the costs associated with our LOGICS and OPTICS trials during the three months ended June 30, 2021.

Research and development expenses were $11.2 million for the six months ended June 30, 2021, a decrease of $2.5 million compared to the six months ended June 30, 2020. The decrease was primarily due to decreases in the costs associated with our LOGICS and OPTICS trials partially offset by increases in regulatory costs associated with our NDA submission during the six months ended June 30, 2021.

Amortization of Intangible Asset

Amortization of intangible asset was $1.3 million and $2.5 million for the three and six months ended June 30, 2021 and 2020, respectively.

Other Expense, Net

The following table summarizes our other income, net, during the three and six months ended June 30, 2021 and 2020:


	Three Months Ended						Six Months Ended
	June 30,				Change		June 30,				Change
	2021		2020		$		2021		2020		$

	(in thousands)						(in thousands)

Total other expense, net	$	(175)	$	(7,594)	$	7,419	$	(1,920)	$	(6,786)	$	4,866

Total other expense, net was $0.2 million in for the three months ended June 30, 2021, compared to other expense, net of $7.6 million in 2020. This $7.4 million decrease was largely due to the net $8.0 million impact from the revaluation of the fair value of our warrant liability mostly due to the change in our volatility and stock price and an additional $0.6 million in interest expense on our Term Loan Agreement which we entered into in May 2020.

Total other expense, net was $1.9 million in for the six months ended June 30, 2021, compared to other expense, net of $6.8 million in 2020. This $4.9 million decrease was largely due to the net $6.7 million impact from the revaluation of the fair value of our warrant liability mostly due to the change in our volatility and stock price and an additional $1.3 million in interest expense on our Term Loan Agreement which we entered into in May 2020.

Income Tax

We recorded income tax expense of $1,000 for the three and six months ended June 30, 2021 and did not record an expense for the three and six months ended June 30, 2020

Cash Flows

Comparison for the Six Months Ended June 30, 2021 and 2020:


	Six Months Ended
	June 30
	2021		2020

	(in thousands)
Net cash (used in) provided by:

Investing activities		(10)		21,122
Financing activities		(518)		9,130
Net (decrease) increase in cash and cash equivalents	$	(23,748)	$	2,877

Operating Activities

Net cash used in operating activities was $23.2 million for the six months ended June 30, 2021, compared to $27.4 million for the six months ended June 30, 2020. The decrease in net cash used in operating activities resulted primarily from an increase of $4.0 million in net revenues.

Table of Contents

Investing Activities

Net cash used in investing activities was insignificant for the six months ended June 30, 2021 compared to proceeds of $21.1 million for the six months ended June 30, 2020. The decrease is due to the sale of marketable securities during the 2020 period. We did not hold marketable securities during the 2021 period.

Financing Activities

The change in net cash used in financing activities was due to payments related to tax withholding of net share settled equity awards offset by stock option exercises and sales of shares under our ATM facility. In addition, the prior period had $9.5 million provided by financing activities due to the proceeds received under our Term Loan Agreement with Avenue Venture Opportunities Fund L.P.

Liquidity and Capital Resources

We continuously and critically review our liquidity and anticipated capital requirements in light of our clinical trial activities and the significant uncertainty created by the COVID-19 global pandemic and the recent emergence of COVID-19 variants.

Cash used to fund operating expenses is affected by the timing of when we make payments to our vendors, as reflected in the change in our outstanding accounts payable and accrued expenses set forth in the consolidated financial statements, included in this Quarterly Report.

Our future funding requirements will depend on many factors, including the following:

●

the amount of revenue that we receive from sales of Keveyis;

●

the cost and timing of establishing sales, marketing, distribution and administrative capabilities;

●

the scope, rate of progress, results and cost of our clinical trials testing and other related activities for Recorlev and veldoreotide and our ability to obtain the necessary regulatory approval of our Recorlev NDA;

●

the number and characteristics of product candidates that we pursue, including any additional product candidates we may in-license or acquire;

●

the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;

●

the cost of defending potential intellectual property disputes, including patent infringement actions brought by third parties against us or our product candidates;

●

the cost, timing and outcomes of regulatory approvals, including product labeling;

●

adequate reimbursement from payors for Keveyis and Recorlev (if approved) on a timely basis;

●

the terms and timing of any collaborative, licensing and other arrangements that we may establish, including any required milestone and royalty payments thereunder;

Table of Contents

●

the emergence of competing technologies and their achieving commercial success before we do or other adverse market developments;

●

the cost, timing and outcome of our anticipated business combination transaction with Xeris Pharmaceuticals, Inc.; and

●

any extended impact of COVID-19 (and related variants).

Long-term Debt

On May 19, 2020, we entered into the $30 million Loan Agreement with Avenue Venture Opportunities Fund L.P. (“Avenue”), as administrative agent and collateral agent, and the lenders named therein and from time to time a party thereto (the “Lenders”). Pursuant to the terms of the Loan Agreement, our wholly-owned subsidiary, Strongbridge U.S. Inc., borrowed $10 million from the Lenders at closing. As a result of achieving positive top-line data for Recorlev in our Phase 3 LOGICS clinical trial in September 2020, we were eligible to and did borrow an additional $10 million under the Loan Agreement on December 30, 2020. The remaining $10 million tranche will become available to us between October 1, 2021, and March 31, 2022, if we achieve FDA approval of Recorlev and subject to Avenue’s investment committee approval.

At-The-Market Facility

We entered into an equity distribution agreement with Jefferies LLC (“Jefferies”) on March 25, 2021, pursuant to which we may sell, at our option, from time to time, up to an aggregate of $50 million of our ordinary shares through Jefferies, as sales agent. We will pay Jefferies a commission equal to 3% of the gross proceeds from the sale of our ordinary shares under this at-the-market (“ATM”) facility. Pursuant to the terms of the equity distribution agreement, we reimbursed Jefferies for certain out-of-pocket expenses, including the fees and disbursements of counsel to Jefferies, incurred in connection with establishing the ATM facility and have provided Jefferies with customary indemnification rights. For the period ended June 30, 2021, we did not sell any shares under this agreement.

Off-Balance Sheet Arrangements

We do not have variable interests in variable interest entities or any off-balance sheet arrangements.
