ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. This discussion contains forwardlooking statements that involve significant risks and uncertainties. Our actual results could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those set forth in Part I, Item 1A. Risk Factors, of this Annual Report on Form 10-K. Overview Unless otherwise indicated, references to "Xeris," the "Company," "we," "our" and "us" in this Annual Report on Form 10-K refer to Xeris Pharmaceuticals, Inc. ("Xeris Pharma") when referring to periods prior to the acquisition of Strongbridge Biopharma plc, an Irish public limited company ("Strongbridge") (discussed below) on October 5, 2021 and to Xeris Biopharma Holdings, Inc. when referring to periods on or subsequent to October 5, 2021. Also, throughout this document, unless otherwise noted, references to Gvoke® include Gvoke PFS, Gvoke HypoPen® and Ogluo®(glucagon). We are a biopharmaceutical company committed to developing and commercializing innovative solutions to enhance the lives of people with life-threatening diseases. Our primary focus is on therapies for patient populations in endocrinology, neurology, and gastroenterology. We currently have three commercially available products, Gvoke, a ready-to-use liquid glucagon for the treatment of severe hypoglycemia, Keveyis, the first and only U.S. Food and Drug Administration (“FDA”) approved therapy for primary periodic paralysis (“PPP”) and Recorlev, approved by the FDA in December 2021 for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s Syndrome. We also have a pipeline of development programs to extend our current marketed products into new indications and uses or bring new products forward using our proprietary formulation technology platforms, XeriSolTM and XeriJectTM. Acquisition of Strongbridge On May 24, 2021, Xeris Pharma and Strongbridge entered into the Transaction Agreement together with Xeris Biopharma Holdings, Inc., a Delaware corporation (“the Company”), and Wells MergerSub, Inc., a Delaware corporation (“MergerSub”) (the “Transaction Agreement”) whereby we would acquire Strongbridge (the “Acquisition”) pursuant to a scheme of arrangement (the “Scheme”) under Irish law. Under the terms of the Transaction Agreement, (i) the Company acquired Strongbridge by means of the Acquisition pursuant to the Scheme and (ii) MergerSub merged with and into Xeris Pharma, with Xeris Pharma as the surviving corporation in the merger (the “Merger,” and the Merger together with the Acquisition, the “Transactions”). As a result of the Transactions, both Xeris Pharma and Strongbridge became wholly owned subsidiaries of the Company. the Company acquired all of the outstanding Strongbridge ordinary shares (“Strongbridge Shares”) in exchange for (i) 0.7840 of a share of the Company’s common stock (“Company Shares”) and cash in lieu of fractions of Company Shares due to a holder of Strongbridge Shares per Strongbridge Share and (ii) one (1) non-tradeable contingent value right, worth up to a maximum of $1.00 per Strongbridge Share settleable in cash, additional Company Shares, or a combination of cash and additional Company Shares, at the Company’s sole discretion. On October 5, 2021, pursuant to the Transaction Agreement, we completed the Transactions. Through the Acquisition, we added Keveyis (dichlorphenamide) to our commercial product portfolio. Keveyis is the first and only treatment approved by 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. In addition, we added a clinical-stage product candidate for rare endocrine diseases, Recorlev. Recorlev (levoketoconazole), the pure 2S,4R enantiomer of the enantiomeric pair comprising ketoconazole, is a next-generation steroidogenesis inhibitor which serves as a chronic therapy for adults with endogenous Cushing’s syndrome. Levoketoconazole has received orphan designation from the FDA and the European Medicines Agency. Recorlev was acquired as an in-process research and development asset and subsequently approved by the FDA on December 30, 2021 for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not been curative. Recorlev was commercially launched in January 2022. Patents We currently own 141 patents issued globally, including a composition of matter patent covering our ready-to-use glucagon formulation that expires in 2036. Upon completion of the Transactions, Xeris Biopharma Holdings, Inc. controls the patents of Xeris Pharma and Strongbridge Dublin Limited, the latter of which has 53 granted patents globally related to proprietary formulations of levoketoconazole (the active pharmaceutical ingredient in Recorlev) and the uses of such formulations in treating certain endocrinerelated diseases and syndromes. This includes US Patent No. 11,020,393, which was granted on June 1, 2021, and which provides patent protection through 2040 for the use of Recorlev in the treatment of certain patients with persistent or recurrent Cushing’s syndrome. Financing We have funded our operations to date primarily with proceeds from the sale of our preferred and common stock and debt financing. We have received gross proceeds of $253.0 million from public equity offerings of our common stock (including our June 2018 initial public offering ("IPO") and our February 2019, February 2020 and June 2020 offerings), $104.9 million from sales of our preferred 77
