Risk factors and legal proceedings
The risks Shattuck Labs, Inc. names in Item 1A of its 10-K filed Mar 5, 2026: 56 risks under these headings, as written.4
- Risks Related to Our Business, Our Financial Condition and Capital Requirements
- We are an early clinical-stage biotechnology company and have incurred significant losses since our inception, and we expect to incur losses for the foreseeable future. We have no products approved for commercial sale, have never generated revenue from product sales, and may never achieve or maintain profitability.
- We will require additional funding in order to complete development of our product candidates, including SL-325, and commercialize our products, if approved. Additional funding may not be available on acceptable terms, or at all. If we are unable to raise capital when needed, we could be forced to delay, reduce, or eliminate our product development programs and other operations.
- Raising additional capital may cause dilution to our existing stockholders, restrict our operations, or require us to relinquish rights to our technologies or product candidates.
- Our ability to compete depends on retaining our key personnel and recruiting additional qualified personnel.
- We have not completed any late-stage clinical trials and have no products approved for commercial sale, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
- Risks Related to the Development and Clinical Testing of Our Product Candidates
- We are substantially dependent on the success of our lead product candidate, SL-325, and our current and any future clinical trials of such product candidate may not be successful.
- SL-325 is in early stages of clinical development and our other product candidates are in preclinical stages of development, and any of our product candidates may fail in development or suffer delays. We depend on the successful initiation and completion of clinical trials for our product candidates to advance our product development plans.
- Preclinical and clinical development is a lengthy and expensive process that is subject to delays and uncertain outcomes, and results of earlier preclinical studies and clinical trials may not be predictive of future clinical trial results. If preclinical studies and clinical trials of our product candidates are prolonged or delayed, we may be unable to obtain required regulatory approvals, and, therefore, be unable to complete the development of and commercialize our product candidates on a timely basis or at all.
- Our clinical trials may fail to demonstrate substantial evidence of the safety and efficacy of our product candidates or any future product candidates, which would prevent, delay or limit both the scope of regulatory approval and our ability to successfully commercialize.
- We may not be successful in our efforts to identify or discover additional product candidates.
The other 46 risks
- We face competition from entities that have developed or may develop programs for the diseases addressed by product candidates developed by us.
- Certain of our programs may compete with our other programs, which could negatively impact our business and reduce our future revenue.
- Our product candidates may have serious adverse, undesirable, or unacceptable side effects or other properties that may delay or prevent marketing approval and our ability to market and derive revenue from our product candidates could be compromised.
- If we experience delays or difficulties initiating clinical trial sites or enrolling patients in our planned clinical trials, our research and development efforts, business, financial condition, and results of operations could be materially and adversely affected.
- We may expend our limited resources to pursue a particular product candidate and fail to capitalize on product candidates that may be more profitable or for which there is a greater likelihood of success.
- Risks Related to Our Regulatory Environment
- The development and commercialization of biopharmaceutical products is subject to extensive regulation, and the regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time-consuming, and inherently unpredictable. If we are ultimately unable to obtain regulatory approval for our product candidates on a timely basis, if at all, our business will be substantially harmed.
- Our product candidates for which we intend to seek approval as biologics may face competition sooner than anticipated.
- We may not be able to meet requirements for the chemistry, manufacturing and control of our programs.
- Disruptions at the FDA and other government agencies could negatively affect the review of our regulatory submissions, which could negatively impact our business.
- Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.
- Current and future laws and regulations may increase the difficulty and cost for us, and any collaborators, to obtain marketing approval of and commercialize our drug candidates and affect the prices we, or they, may obtain.
- Our business operations and current and future relationships with healthcare professionals, principal investigators, consultants, vendors, customers, and third-party payors are subject to applicable healthcare laws, which could expose us to penalties.
- Our employees, independent contractors, principal investigators, contract research organizations (“CROs”), consultants, commercial partners, suppliers, and vendors acting for us or on our behalf may engage in misconduct or other improper activities, including noncompliance with applicable laws and regulations.
- If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
- Risks Related to Our Dependence on Third Parties
- We rely on third parties to supply raw materials and to manufacture our product candidates. The manufacture of our product candidates is complex and our third-party manufacturers may encounter difficulties in production, which could delay or entirely halt their ability to supply our product candidates for clinical trials or, if approved, for commercial sale.
- We rely, and expect to continue to rely, on third parties to conduct preclinical studies, nonclinical studies, and clinical trials. If these third parties do not successfully carry out their contractual duties, comply with applicable regulatory requirements, or meet expected deadlines, we may not be able to obtain regulatory authorizations or approvals required to develop or commercialize our product candidates and our business could be materially and adversely affected.
- We may not realize the benefits of any future collaboration or licensing arrangement, and if we fail to enter into new strategic relationships our business, financial condition, commercialization prospects, and results of operations may be materially and adversely affected.
- If we are unable to obtain sufficient raw and intermediate materials on a timely basis or if we experience other supply difficulties, our business may be materially and adversely affected.
- Risks Related to Intellectual Property and Information Technology
- Our success depends upon our ability to obtain and maintain patents and other intellectual property rights to protect our technology, including SL-325, methods used to manufacture our product candidates, formulations thereof, and the methods for treating patients using those product candidates.
- Others may challenge our patents or other intellectual property as invalid or unenforceable.
- Our commercial success depends, in part, on our ability to develop, manufacture, market, and sell our product candidates without infringing or otherwise violating the intellectual property and other proprietary rights of third parties.
- We rely, in part, on in-licensed patents and other intellectual property rights to develop and commercialize our product candidates. We may need to obtain additional licenses of third-party technology that may not be available to us or are available only on commercially unreasonable terms, and which may cause us to operate our business in a more costly or otherwise adverse manner that was not anticipated.
- We may depend on intellectual property licensed from third parties and if we fail to comply with our obligations under any license or other agreements, we may be required to pay damages and could lose intellectual property rights that are necessary for developing and protecting our product candidates or we could lose certain rights to grant sublicenses.
- We may enjoy only limited geographical protection with respect to certain patents and may not be able to protect our intellectual property rights throughout the world.
- Changes in patent laws in the United States and in foreign jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.
- We may become subject to claims challenging the inventorship or ownership of our patents and other intellectual property.
- Intellectual property rights do not necessarily address all potential threats to our competitive advantage.
- We rely on trade secret and proprietary know-how, which can be difficult to trace and enforce and, if we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
- Any sort of contested proceeding related to intellectual property, whether offensive or defensive, may cause us to incur significant expenses and would be likely to divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities, and may impact our reputation.
- Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.
- Our information technology systems, or those used by our CROs or other contractors or consultants, may fail or suffer security breaches, which could materially and adversely affect our business.
- Risks Related to Ownership of Our Common Stock
- Our stock price may be volatile or may decline regardless of our operating performance, resulting in substantial losses for investors.
- Our principal stockholders and management own a significant percentage of our stock and are able to exert significant control over matters subject to stockholder approval.
- A sale of a substantial number of shares of our common stock may cause the price of our common stock to decline.
- Because we do not anticipate paying any dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.
- General Risk Factors
- Our business could be adversely affected by economic downturns, inflation, fluctuating interest rates, changes in trade policies, including tariffs or other trade restrictions or the threat of such actions, natural disasters, public health crises, such as pandemics, political crises, geopolitical events, or other macroeconomic conditions, which could have a material and adverse effect on our results of operations and financial condition.
- Adverse developments affecting the financial services industry, including events or concerns involving liquidity, defaults or non-performance by financial institutions or transactional counterparties, could adversely affect our business, financial condition or results of operations.
- If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business or our market, or if they change their recommendations regarding our common stock adversely, the trading price or trading volume of our common stock could decline.
- The requirements of being a public company may strain our resources, result in litigation, and divert management’s attention.
- Litigation filed against us could harm our business, and insurance coverage may not be sufficient to cover all related costs and damages.
- We may become exposed to costly and damaging liability claims, either when testing a product candidates in the clinic or at the commercial stage, and our product liability insurance may not cover all damages from such claims.
- If we fail to maintain proper and effective internal controls over financial reporting our ability to produce accurate and timely financial statements could be impaired.
- Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.
- Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws and Delaware law might discourage, delay, or prevent a change in control of our company or changes in our management and, therefore, depress the market price of our common stock.
- Our amended and restated 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, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes.
- Our ability to use our net operating loss carryforwards and other tax attributes may be limited.
Legal proceedings
From time to time, we may be involved in legal proceedings, claims, investigations and government inquiries arising in the ordinary course of our business. We are not presently a party to any material legal proceedings, and we are not currently aware of any pending or threatened legal proceeding against us that, in the opinion of our management and if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows.
