Risk factors and legal proceedings
The risks OmniAb, Inc. names in Item 1A of its 10-K filed Mar 4, 2026: 74 risks under these headings, as written.3
- Risks Related to Our Business
- Biopharmaceutical development is inherently uncertain, and it is possible that none, or very few, of the therapeutic candidates discovered using our platform that are further developed by our partners will become viable commercial products, on a timely basis or at all.
- Our partners may not achieve projected discovery and development milestones and other anticipated key events in the expected timelines or at all, which could have an adverse impact on our business and could cause the price of our common stock to decline.
- The failure of our partners to meet their contractual obligations to us could adversely affect our business.
- Our partners have significant discretion in determining when and whether to make announcements, if any, about the status of our partnerships or programs, including about clinical developments and timelines for advancement, and the price of our common stock may decline as a result of announcements of unexpected results or developments.
- Our commercial success depends on the quality of our antibody discovery platform and technological capabilities and their acceptance by new and existing partners in our market.
- Our future success is dependent on the approval and commercialization of products developed by our partners for which we have no control over the clinical development plan, regulatory strategy or commercialization efforts.
- If we cannot maintain and expand current partnerships and enter into new partnerships, our future operating results would be adversely affected.
- We may need to raise additional capital to fund our existing operations and achieve our goals. If we are unable to raise additional capital when needed on acceptable terms or generate cash flows necessary to maintain or expand our operations, we may not be able to compete successfully, which would harm our business, results of operations, and financial condition.
- In recent periods, we have depended on a limited number of partners for our revenue, the loss of any of which could have an adverse impact on our business.
- Our revenue has fluctuated from period to period, and our revenue for any historical period may not be indicative of results that may be expected for any future period.
- We have incurred losses on an as-reported basis for the last several years, and we may not be able to generate sufficient revenue to achieve and maintain profitability.
The other 63 risks
- Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.
- Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.
- Our management uses certain key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions, and such metrics may not accurately reflect all of the aspects of our business needed to make such evaluations and decisions, in particular as our business continues to grow.
- The sizes of the markets and forecasts of market growth for the demand of our OmniAb technology platform and other of our key performance indicators are based on a number of complex assumptions and estimates, and may be inaccurate.
- We may be unable to manage our current and future growth effectively, which could make it difficult to execute our business strategy.
- Our platform utilizes various species of animals that could contract disease or die and could otherwise subject us to controversy and adverse publicity, which may interrupt our business operations or harm our reputation.
- The life sciences and biotech platform technology market is highly competitive, and if we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenue, or sustain profitability.
- We rely on third parties to host our mouse and rat colonies, and these third parties may not perform satisfactorily which could delay, prevent or impair our partnerships, programs and research and technology development efforts.
- We have invested, and expect to continue to invest, in research and development efforts that further enhance our antibody discovery platform. Such investments in technology are inherently risky and may affect our operating results. If the return on these investments is lower or develops more slowly than we expect, our revenue and operating results may suffer.
- Third-party payor coverage and reimbursement status of newly approved therapeutics is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for current or future products and services could limit our partners’ ability to fully commercialize therapeutic candidates generated using our platform, which would decrease our ability to generate revenue.
- Healthcare reform efforts aimed at lowering the price of biopharmaceutical products may impact our ability to maintain sufficient profits.
- U.S. legislation, sanctions, tariffs, trade restrictions and other foreign regulatory requirements could increase costs and adversely impact the supply of material from foreign CROs and CMOs to us and our partners or our partners’ ability to secure government commitments to purchase potential therapies.
- We rely on a limited number of suppliers for equipment and materials used in our laboratory or sold to partners and may not be able to find replacements or immediately transition to alternative suppliers.
- We must adapt to rapid and significant technological change and respond to introductions of new products and technologies by competitors to remain competitive.
- We depend on our information technology systems, and any failure of these systems could harm our business.
- Our success is dependent on our ability to attract and retain highly qualified management and other scientific and engineering personnel.
- We have made technology acquisitions and expect to acquire businesses or assets or make investments in other companies or technologies that could negatively affect our operating results, dilute our stockholders’ ownership, or cause us to incur debt or significant expense.
- If our operating facilities become damaged or inoperable or if we move or are otherwise required to vacate our facilities, our ability to conduct and pursue our research and development efforts may be jeopardized.
- Our insurance policies are expensive and protect us only from some business risks, which leaves us exposed to significant uninsured liabilities.
- Security breaches, loss of data and other disruptions could compromise sensitive information related to our business or prevent us from accessing critical information and expose us to liability, which could adversely affect our business and our reputation.
- Our business could become subject to more extensive government regulation than we currently anticipate, and regulatory compliance obligations and the investigational exemption and approval processes to which our animals may become subject are expensive, time-consuming and uncertain both in timing and in outcome.
- Our business operations and current and future relationships with investigators, healthcare professionals, and partners may be subject to applicable fraud and abuse and other healthcare laws and regulations, which could expose us and/or our partners to criminal sanctions, civil penalties, exclusion from government healthcare programs, contractual damages, reputational harm and diminished profits and future earnings.
- Changes in and actual or perceived failures to comply with applicable data privacy, security and protection laws, regulations, standards and contractual obligations may adversely affect our business, operations and financial performance.
- Our portfolio of investments or bank deposits may be subject to market, interest and credit risk that may reduce their value and adversely affect our business, results of operations and financial condition.
- Risks Related to Our Intellectual Property
- If we are unable to obtain and maintain sufficient intellectual property protection for our platform and technology, 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 platform and services may be impaired.
- Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our technology.
- Issued patents directed to our platform and technology could be found invalid or unenforceable if challenged in court or before administrative bodies in the United States or abroad.
- We rely on in-licenses from third parties. If we lose these rights, our business may be materially and adversely affected, our ability to develop improvements to our technology platform and antibody discovery platform may be negatively and substantially impacted, and if disputes arise, we may be subjected to future litigation, as well as the potential loss of or limitations on our ability to incorporate the technology covered by these license agreements.
- If we cannot acquire or license rights to use technologies on reasonable terms or if we fail to comply with our obligations under such agreements, we may not be able to commercialize new technologies or services in the future and our business could be harmed.
- We may not be able to protect our intellectual property rights throughout the world.
- Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
- If we are unable to protect the confidentiality of our information and our trade secrets, the value of our technology could be materially and adversely affected and our business could be harmed.
- We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.
- We may not be able to protect and enforce our trademarks and trade names, or build name recognition in our markets of interest thereby harming our competitive position.
- We may be subject to claims challenging the inventorship of our patents and other intellectual property.
- We may from time to time become involved in litigation and other proceedings related to intellectual property, which could be time-intensive and costly and may adversely affect our business, financial condition, results of operations and prospects.
- Obtaining and maintaining our patent protection depends on compliance with various required procedures, document submissions, fee payments and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.
- Patent terms may be inadequate to protect our competitive position on our technology for an adequate amount of time.
- Our use of open source software could compromise our ability to offer our data packages and subject us to possible litigation.
- Some of our intellectual property rights may have been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers.
- General Risk Factors
- Our employees, consultants and partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, and insider trading.
- We use biological and hazardous materials that require considerable expertise and expense for handling, storage and disposal and may result in claims against us.
- We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws and anti-money laundering laws and regulations. We could face criminal liability and other serious consequences for violations, which could harm our business.
- Unstable market and economic conditions and adverse developments with respect to financial institutions and associated liquidity risk may have serious adverse consequences on our business, financial condition and stock price.
- We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives.
- Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
- Our failure to meet the continued listing requirements of the Nasdaq Global Market or the Nasdaq Capital Market, as applicable, could result in a delisting of our common stock or warrants.
- Risks Related to Our Common Stock and Warrants
- The market price of our common stock and warrants is likely to be highly volatile, and you may lose some or all of your investment.
- Volatility in our share price could subject us to securities class action litigation.
- Affiliates of Avista Capital Partners own a significant equity interest in the Company and may take actions that conflict with the interests of our public stockholders.
- If securities or industry analysts do not publish research or reports about us, or publish negative reports, our stock price and trading volume could decline.
- We do not currently intend to pay dividends on our common stock, and, consequently, your ability to achieve a return on your investment will depend on appreciation, if any, in the price of our common stock.
- Sales of a substantial number of our securities in the public market by our existing securityholders could cause the prices of our common stock and warrants to fall.
- Certain existing stockholders purchased our shares at a price below the current trading price of such shares, and may experience a positive rate of return based on the current trading price. Our future investors may not experience a similar rate of return.
- Provisions in our certificate of incorporation and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.
- Our certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders and that the federal district courts shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees or the underwriters or any offering giving rise to such claim.
- The exclusive forum clause set forth in the Warrant Agreement may have the effect of limiting an investor’s rights to bring legal action against us and could limit the investor’s ability to obtain a favorable judicial forum for disputes with us.
- We are an emerging growth company and smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies and smaller reporting companies will make our shares less attractive to investors.
- If our estimates or judgments relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our results of operations could be adversely affected.
- If securityholders exercise their Public Warrants on a “cashless basis,” they will receive fewer shares of common stock from such exercise than if such securityholders were to exercise such Warrants for cash.
- There is no guarantee that the exercise price of the Public Warrants will ever be less than the trading price of our common stock on Nasdaq, and they may expire worthless, and the terms of the Public Warrants may be amended in a manner adverse to a holder if holders of at least 50% of the then outstanding Public Warrants approve of such amendment.
- Warrants are exercisable for shares of common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.
- We may redeem unexpired Public Warrants prior to their exercise at a time that is disadvantageous to securityholders, thereby making such Public Warrants worthless.
Legal proceedings
From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations. However, regardless of outcome, litigation can have an adverse impact on our business because of defense
and settlement costs, diversion of management resources and other factors, and there can be no assurances that favorable outcomes will be obtained.
