SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K (this “Annual Report”) contains forward-looking statements. All statements other than statements of historical facts contained in this Annual Report including statements regarding our commercial strategy; potential value drivers; potential indications; potential market opportunities and competitive position; ongoing, planned and potential clinical trials and other studies; timing and potential impact of clinical data; future results of operations and financial position; expected timeline for our cash, cash equivalents and short-term investments; product development; prospective products and product candidates; supply of drug products at acceptable cost and quality; collaborators, license and other strategic arrangements; the expected timeline for achievement of our clinical milestones; potential marketing authorization from the U.S. Food and Drug Administration (the “FDA”) or regulatory authorities in other jurisdictions; potential and ongoing coverage and reimbursement for our products and product candidates, if approved; clinical and commercial activities; research and development costs; timing of regulatory filings and feedback; timing and likelihood of success; and plans and objectives of management for future operations and funding requirements, are forward-looking statements.

These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “goal,” “design,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these identifying words. The forward-looking statements in this Annual Report are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. These forward-looking statements speak only as of the date of this Annual Report and are subject to a number of risks, uncertainties and assumptions described under the sections in this Annual Report entitled “Summary Risk Factors”, “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Annual Report. These forward-looking statements are subject to numerous risks and uncertainties, including, without limitation, the following:

●our continued ability to commercialize ARCALYST® (rilonacept) and to develop and commercialize our current and future product candidates, if approved;
●our expectation to incur losses for the foreseeable future in light of our future capital needs, potentially requiring us to raise additional funds;
●our ability to source sufficient quantities of our products and product candidates to meet patient and partner demand at acceptable cost and quality specifications;
●our ability to successfully complete the technology transfer of the manufacturing process for ARCALYST drug substance;
●the market acceptance of our products and product candidates;
●competitive and potentially competitive products and technologies;
●prescriber awareness and adoption of our products and product candidates, if approved;
●the size of the market for our products and product candidates, if approved;
●the decision of third party payors not to cover or maintain coverage of or to establish burdensome requirements prior to covering or maintaining coverage of ARCALYST or any of our current or future product candidates, if approved;
●the lengthy and expensive clinical development process with its uncertain outcomes and potential for clinical failure or delay;
●the decision by any applicable regulatory authority to permit clinical development of, to grant regulatory exclusivity for and to approve marketing and sale of our current and future product candidates;
●our ability to anticipate and prevent adverse events caused by our products and product candidates;
●our ability to identify, in-license, acquire, discover or develop additional product candidates;
●our ability to undertake and execute on business combinations, out-licensing activities, collaborations or other strategic transactions and our ability to realize value therefrom;
●potential product liability claims;
●federal, state and foreign regulatory requirements applicable to our products and product candidates;
●our ability to obtain, maintain, protect and enforce our intellectual property rights related to our products and product candidates; and
●our ability to attract and retain skilled personnel.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not place undue reliance on our forward-looking statements. Except as required by applicable law, we do not assume and specifically disclaim any obligation to update any forward-looking statements, whether as a result of any new information, future events, changed circumstances or otherwise.

SUMMARY RISK FACTORS

Our business is subject to numerous risks and uncertainties, including those described in Part I, Item 1A. “Risk Factors” in this Annual Report. You should carefully consider these risks and uncertainties when investing in our Class A common shares. The principal risks and uncertainties affecting our business include the following:

●we have a history of operating losses and expect to incur operating losses for the foreseeable future;
●to further our operational plans, we may require substantial additional financing, which we may not be able to obtain when needed or on acceptable terms;
●we may not be able to continue to commercialize ARCALYST or be successful in commercializing any future products, which may materially impact our ability to generate revenue;
●successful commercialization of our products and product candidates, if approved, will depend in part on the extent to which third party payors, including governmental authorities and private health insurers, provide funding, establish and maintain favorable coverage and pricing policies and set adequate reimbursement levels;
●if we are unable to advance our product candidates in clinical development, obtain regulatory approval and pursue commercialization, or experience significant delays in doing so, our business may be materially harmed;
●the incidence and prevalence for target patient populations of our products and product candidates have not been established with precision; if the market opportunities for our products and product candidates are smaller than we estimate, or any approval that we obtain is based on a narrower definition of our targeted patient population, our revenue and ability to achieve profitability may be materially adversely affected;
●clinical development of our product candidates is a lengthy and expensive process with uncertain timelines, costs and outcomes;
●we may encounter substantial delays in our preclinical studies and/or clinical trials, including as a result of delays in obtaining regulatory approvals to conduct clinical trials, activating sites, enrolling participants, and conducting trials, which could delay or prevent our product development activities;
●we rely on third parties, including independent contract development and manufacturing organizations (“CDMOs”) to manufacture our commercial supply of ARCALYST and our product candidates for preclinical and clinical development; and if these third parties do not have sufficient manufacturing capacity at our desired times or otherwise fail to perform satisfactorily, including by producing insufficient supply of commercial and clinical stock to meet patient demand or clinical trial requirements, or are impacted by delays or supply shortages, our product development activities, regulatory approval, and commercialization efforts may be delayed, prevented or impaired;
●we are conducting a technology transfer of the manufacturing process for ARCALYST drug substance from Regeneron Pharmaceuticals, Inc. (“Regeneron”) to a new CDMO, and the analytical testing methods of ARCALYST drug substance and drug product to new contract testing labs (“CTLs”) and the process to complete the technology transfer and qualify a new CDMO may be subject to significant risks and uncertainties;
●we rely, and expect to continue to rely, on third parties, including independent investigators and contract research organizations (“CROs”) to activate sites, conduct or otherwise support our research activities, preclinical studies, clinical trials and other trials for our product candidates; if these third parties do not perform satisfactorily or comply with regulatory requirements, our product development activities may be delayed, prevented or impaired and our business could be substantially harmed;
●for our products and product candidates that have been licensed or acquired from other parties, if those parties did not adequately protect and we are unable to adequately protect such products and product candidates, or to secure and maintain freedom to operate, others could preclude us from commercializing such products and product candidates, if approved, or compete against us more directly;
●If the scope of our patent protection is not sufficiently broad or the terms of our patents are insufficient to protect our products and product candidates for an adequate amount of time, our competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be materially impaired;
●we face significant competition from other biotechnology and pharmaceutical companies, which may result in others discovering, developing or commercializing drugs before or more successfully than us;
●we may not successfully execute our growth strategy to identify, discover, develop, license or acquire additional product candidates or technologies, our strategy may not deliver anticipated results or we may refine or otherwise alter our growth strategy;
●we may seek to acquire businesses or undertake business combinations, collaborations or other strategic transactions which may not be successful or on favorable terms, if at all, and we may not realize the intended benefits of such transactions;
●we have entered into and may seek to enter into collaboration, licensing or other strategic transactions or arrangements to further develop, commercialize or otherwise attempt to realize value from one or more of our products and product candidates; such arrangements or transactions may not be successful or on favorable terms, which could adversely affect our ability to develop, commercialize or attempt to realize value from our products and product candidates; and
●concentration of ownership of the voting power of our common shares, including our Class B common shares, and conversion rights of the holders of our Class A1 and Class B1 common shares, which are held primarily by entities affiliated with certain of our directors, may prevent new investors from influencing significant corporate decisions and may have an adverse effect on the price of our Class A common shares.
