Summary of the Material and Other Risks Associated with Our Business

Our business is subject to numerous material and other risks and uncertainties. You should carefully consider the following information together with the other information appearing elsewhere in this Quarterly Report, including our financial statements and related notes hereto. The occurrence of any of the following risks could have a material adverse effect on our business, financial condition, results of operations and future growth prospects. The risks and uncertainties described below may change over time and other risks and uncertainties, including those that we do not currently consider material, may impair our business. These risks include, but are not limited to, the following:

•We have incurred losses in certain years since inception, including in 2025, and we may not be able to generate sufficient revenue to achieve profitability.

•Our quarterly and annual operating results have fluctuated significantly in the past and may fluctuate significantly in the future, making it difficult to predict our future operating results and could cause our operating results to fall below expectations.

•Our commercial success depends on the quality of our antibody discovery and development capabilities, technological capabilities, the advancement of internal programs, and their acceptance by new and existing partners in our industry.

•Failure to execute our business strategy could adversely impact our growth and profitability.

•Development of a biological molecule is inherently uncertain, and it is possible that none of the antibody drug candidates discovered using our antibody discovery and development capabilities that are further developed by us or our partners will receive marketing approval or become viable commercial products, on a timely basis or at all.

•Our partners have significant discretion in determining when and whether to make announcements, if any, about the status of our partnerships, including about clinical developments and timelines for advancing collaborative programs with the antibodies that we have discovered, and the price of our common shares may decline as a result of announcements of unexpected results or developments.

•We may not be able to file applications or amendments to commence additional clinical trials on the timelines we expect, and even if we are able to, the regulatory body may not permit us to proceed.

•We have no marketed proprietary products and have not yet independently started clinical development, which makes it difficult to assess our ability to independently develop future product candidates and monetize any resulting products.

•We have a limited number of product candidates. If we do not obtain regulatory approval of one or more of our product candidates, or experience significant delays in doing so, our business will be materially adversely affected.

•Our long-term prospects depend in part upon discovering, developing and commercializing additional product candidates, which may fail in development or suffer delays that adversely affect their commercial viability.

•We face significant competition, and if our competitors develop and market products that are more effective, safer or less expensive than our product candidates, our commercial opportunities will be negatively impacted.

•Upgrading and integrating our business systems could result in implementation issues and business disruptions.

•If we are unable to obtain and maintain sufficient intellectual property protection for our technology, including our discovery and development capabilities, or if the scope of the intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize technologies or a platform similar or identical to ours, and our ability to successfully sell our data packages may be impaired.

•We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time consuming and unsuccessful and have a material adverse effect on the success of our business.

•If we fail to maintain proper and effective internal control over financial reporting, our operating results and our ability to operate our business could be harmed.

•Sales of a substantial number of our common shares in the public market could cause our share price to fall significantly, even if our business is doing well.

•Impairment charges pertaining to goodwill, identifiable intangible assets or other long-lived assets could have an adverse non-cash accounting impact on our results of operations.

ii

•The market price of our common shares may be volatile, and you could lose all or part of your investment.

Investing in our common shares involves a high degree of risk. You should carefully consider the risks and uncertainties contained in Part II, Item 1A, Risk Factors, together with all other information in this Quarterly Report on Form 10-Q, including our consolidated financial statements and related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as our other filings with the Securities and Exchange Commission, or the SEC, before investing in our common shares. Any of the risk factors we describe below under Part II, Item 1A, Risk Factors, could adversely affect our business, financial condition or results of operations. The market price of our common shares could decline if one or more of these risks or uncertainties were to occur, which may cause you to lose all or part of the money you paid to buy our common shares. Additional risks that are currently unknown to us or that we currently believe to be immaterial may also impair our business. Certain statements below are forward-looking statements. See “Forward-Looking Information” in this Quarterly Report on Form 10-Q.
