As previously announced on May 24, 2021, Strongbridge and Xeris entered into a definitive transaction agreement under which Xeris will acquire Strongbridge in a stock and CVR transaction for a transaction equity value of 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. The Acquisition will be effected by means of a "scheme of arrangement" under Chapter 1 of Part 9 of the Irish Companies Act of 2014.

Holders of Strongbridge ordinary shares as of 5:00 p.m. ET in the U.S. on July 27, 2021 will be entitled to vote at the special meetings. The first meeting, which is the special meeting called by the Irish High Court, will be held on September 8, 2021 at 12:00 p.m. ET in the U.S. (5:00 p.m. Irish Time), at 900 Northbrook Drive, Suite 200, Trevose, Pennsylvania, 19053, USA.

Shareholders in Ireland may participate in the special meetings by audio link at the offices of Arthur Cox LLP, Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland.

Strongbridge expects to begin mailing a joint proxy statement/prospectus to its shareholders in the coming days. The proxy statement will also constitute a scheme circular under Irish law and will provide important information about the Acquisition for Strongbridge shareholders as well as instructions for shareholders on voting online, by mail, by telephone or in person.

In addition, in accordance with Rule 15(c) of the Irish Takeover Rules, joint letters from Strongbridge and Xeris containing details of the proposals (the "Proposals") to the holders of Strongbridge equity awards and restricted stock units and, separately, to the holders of Strongbridge warrants in connection with the Acquisition, will shortly be despatched to such holders.

This announcement contains certain forward-looking statements with respect to a proposed transaction involving Xeris and Strongbridge and Xeris', Strongbridge's and/or the combined group's estimated or anticipated future business, performance and results of operations and financial condition, including estimates, forecasts, targets and plans for Xeris and Strongbridge and, following the Acquisition, if completed, the combined group. The words "believe," "expect," "anticipate," "project" and similar expressions, among others, generally identify forward looking statements. These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those indicated in the forward-looking statements. Such risks and uncertainties include, but are not limited to, the possibility that a possible acquisition will not be pursued, failure to obtain necessary shareholder or regulatory approvals or required financing or to satisfy any of the other conditions to the possible acquisition, the reaction of Xeris' and Strongbridge's shareholders to the proposed transaction, adverse effects on the market price of Xeris shares of common stock ("Xeris Shares") or Strongbridge ordinary shares ("Strongbridge Shares") and on Xeris' or Strongbridge's operating results because of a failure to complete the possible acquisition, failure to realize the expected benefits of the possible acquisition, failure to promptly and effectively integrate Strongbridge's businesses, negative effects relating to the announcement of the possible acquisition or any further announcements relating to the possible acquisition or the consummation of the possible acquisition on the market price of Xeris Shares or Strongbridge Shares, significant transaction costs and/or unknown or inestimable liabilities, the risk that any potential payment of proceeds pursuant to the CVR Agreement may not be distributed at all or result in any value to Strongbridge shareholders, potential litigation associated with the possible acquisition, general economic and business conditions that affect the combined companies following the consummation of the possible acquisition, the impact of the COVID-19 pandemic on Xeris' or Strongbridge's businesses or the combined businesses following the consummation of the transaction, changes in global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax laws, regulations, rates and policies, future business acquisitions or disposals and competitive developments. These forward-looking statements are based on numerous assumptions and assessments made in light of Xeris' or, as the case may be, Strongbridge's experience and perception of historical trends, current conditions, business strategies, operating environment, future developments and other factors it believes appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this announcement could cause Xeris' plans with respect to Xeris or Strongbridge, Strongbridge's or Xeris' actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to have been correct and persons reading this announcement are therefore cautioned not to place undue reliance on these forward-looking statements which speak only as at the date of this announcement. Additional information about economic, competitive, governmental, technological and other factors that may affect Xeris is set forth in Item 1A, "Risk Factors," in Xeris' 2020 Annual Report on Form 10-K, which has been filed with the SEC, the contents of which are not incorporated by reference into, nor do they form part of, this announcement. Additional information about economic, competitive, governmental, technological and other factors that may affect Strongbridge is set forth in Item 1A, "Risk Factors," in Strongbridge's 2020 Annual Report on Form 10-K, which has been filed with the SEC, the contents of which are not incorporated by reference into, nor do they form part of, this announcement.

Any forward-looking statements in this announcement are based upon information available to Xeris, Strongbridge and/or their respective boards of directors, as the case may be, as of the date of this announcement and, while believed to be true when made, may ultimately prove to be incorrect. Subject to any obligations under applicable law, none of Xeris, Strongbridge or any member of their respective boards of directors undertakes any obligation to update any forward-looking statement whether as a result of new information, future developments or otherwise, or to conform any forward-looking statement to actual results, future events, or to changes in expectations. All subsequent written and oral forward-looking statements attributable to Xeris, Strongbridge or their respective boards of directors or any person acting on behalf of any of them are expressly qualified in their entirety by this paragraph.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Irish Takeover Rules, if any person is, or becomes, ‘interested' (directly or indirectly) in 1% or more of any class of ‘relevant securities' of Strongbridge or Xeris, all ‘dealings' in any ‘relevant securities' of Strongbridge or Xeris (including by means of an option in respect of, or a derivative referenced to, any such ‘relevant securities') must be publicly disclosed by not later than 3:30 p.m. (New York time) on the ‘business' day following the date of the relevant transaction. This requirement will continue until the date on which the Scheme becomes effective or on which the ‘offer period' otherwise ends. If two or more persons cooperate on the basis of any agreement, either express or tacit, either oral or written, to acquire an ‘interest' in ‘relevant securities' of Strongbridge or Xeris, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

Under the provisions of Rule 8.1 of the Irish Takeover Rules, all ‘dealings' in ‘relevant securities' of Strongbridge by Xeris or ‘relevant securities' of Xeris by Strongbridge, or by any party acting in concert with either of them, must also be disclosed by no later than 12 noon (New York time) on the ‘business' day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose ‘relevant securities' ‘dealings' should be disclosed, can be found on the Panel's website at www.irishtakeoverpanel.ie.

‘Interests in securities' arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an ‘interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in single quotation marks are defined in the Irish Takeover Rules, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a dealing under Rule 8, please consult the Panel's website at www.irishtakeoverpanel.ie or contact the Panel on telephone number +353 1 678 9020.
