The risk factor titled “Changes in tax law may materially adversely affect our financial condition, results of operations, and cash flows, or adversely impact the value of an investment in our common stock.” from our Annual Report on Form 10-K for the year ended December 31, 2024 is amended and restated as follows:

Current report

Changes in tax laws or in their implementation or interpretation may materially adversely affect our financial condition, results of operations, and cash flows, or adversely impact the value of an investment in our common stock.

Current report

New income, sales, use, or other tax laws, statutes, rules, regulations, or ordinances could be enacted or amended at any time, or interpreted, changed, modified, or applied adversely to us, any of which could adversely affect our business operations and financial performance. For example, the Inflation Reduction Act (IRA) was signed into law in August 2022, and the One Big Beautiful Bill Act (OBBBA) was signed into law in July 2025. The OBBBA contains numerous tax provisions that we are currently in the process of evaluating, and which may affect our business or financial condition. Regulatory guidance under the IRA, the OBBBA, and other tax-related legislation is and continues to be forthcoming, and such guidance could ultimately increase or lessen the impact of these laws on our business and financial condition. In addition, it is uncertain if and to what extent various states will conform to changes to federal tax legislation. We urge our investors to consult with their legal and tax advisors with respect to any changes in tax law and the potential tax consequences of investing in our common stock.

The risk factor titled “Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain, or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved, or commercialized in a timely manner or at all, which could negatively impact our business.” from our Annual Report on Form 10-K for the year ended December 31, 2024 is amended and restated as follows:

Current report

The ability of the FDA and other government agencies to review and approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, a government agency’s ability to hire and retain key personnel and accept the payment of user fees, government shutdowns and other events that may otherwise affect the government agency’s ability to perform routine functions. Average review times at the FDA and other government agencies have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new drugs or modifications to approved drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times, including the ongoing shutdown that began on October 1, 2025, and certain regulatory agencies, such as the FDA, have had to furlough critical employees and stop critical activities.

Current report

Separately, in response to the COVID-19 pandemic, the FDA postponed most inspections of domestic and foreign manufacturing facilities at various points. While the COVID-19 pandemic is no longer having a significant disruptive impact on the FDA’s standard inspection operations of domestic and foreign manufacturing facilities, it is possible that another global pandemic could result in similar issues faced during the COVID-19 pandemic. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in the future. If the current government shutdown continues or a new government shutdown occurs, or if future global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, including our planned NDA for lorundrostat, which could have a material adverse effect on our business.
