RISK FACTORS SUMMARY

Our business, results of operations, financial condition, and growth prospects may be affected by a number of factors, whether currently known or unknown. Any one or more of such factors could directly or indirectly cause our actual results of operations and financial condition to vary materially from past or anticipated future results of operations and financial condition. Any of these factors, in whole or in part, let alone combined with any of the others, could materially and adversely affect our business, financial condition, results of operations, and stock price. We have provided a summary of some of these risks below, with a more detailed explanation of those and other risks applicable to the Company in Part I, Item 1A. “Risk Factors” in this Annual Report.

Summary of Risks Related to Our Business

The principal risks and uncertainties affecting our business include the following:

•We have a limited operating history and none of lorundrostat or any future product candidates have been approved for commercial sale. We have a history of significant net losses since our inception and expect to continue to incur significant losses for the foreseeable future. We may never generate any revenue or become profitable or, if we achieve profitability, we may not be able to sustain it.

•We will need substantial additional funds to pursue our business objectives, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed on acceptable terms, or at all, may force us to delay, limit, reduce, or terminate our product development programs, commercialization efforts, or other operations.

•Our future performance at this time is entirely dependent on the success of our only product candidate, lorundrostat, which is currently in clinical development and has not completed a pivotal trial. If we are unable to advance lorundrostat in clinical development, obtain regulatory approval, and ultimately commercialize lorundrostat, or experience significant delays in doing so, our business will be materially harmed.

•Clinical and preclinical development involves a lengthy and expensive process with uncertain timelines and outcomes, and results of prior clinical trials and studies of lorundrostat are not necessarily predictive of future results. Lorundrostat may not achieve favorable results in our clinical trials or receive regulatory approval on a timely basis, if at all.

•Use of lorundrostat or any future product candidates could be associated with adverse side effects, adverse events, or other properties or safety risks, which could delay or preclude regulatory approval, cause us to suspend or discontinue clinical trials, abandon a product candidate, limit the commercial profile of an approved label, or result in other significant negative consequences that could severely harm our business, prospects, operating results, and financial condition.

•We heavily rely on our exclusive license agreement entered into in July 2020 (Mitsubishi License) with Mitsubishi Tanabe Pharma Corporation (Mitsubishi Tanabe) to provide us with intellectual property rights to develop and commercialize lorundrostat. If the Mitsubishi License is terminated, we would lose our rights to develop and commercialize lorundrostat, which in turn would have a material adverse effect on our business, financial condition, results of operations, and prospects, including, but not limited to, cessation of our operations to the extent we are unable to develop other product candidates at the time of such termination.

•We face significant competition, and if our competitors develop and commercialize technologies or product candidates more rapidly than we do, or their technologies or product candidates are more effective, safer, or less expensive than lorundrostat and any future product candidates we develop, our business and our ability to develop and successfully commercialize products will be adversely affected.

•We rely on and intend to continue to rely on third parties to conduct, supervise, and monitor our clinical trials and preclinical studies. If these third parties do not successfully carry out their contractual duties, comply with applicable regulatory requirements, or meet expected deadlines, our development programs and our ability to seek or obtain regulatory approval for or commercialize lorundrostat and any future product candidates may be delayed or subject to increased costs, each of which may have an adverse effect on our business and prospects.

•If we are unable to obtain, maintain, and enforce patent or other intellectual property protection for lorundrostat or any future product candidates or technology, or if the scope of the patent or other intellectual property protection obtained is not sufficiently broad, our competitors or other third parties could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize lorundrostat or any future product candidates may be adversely affected.

•The trading price of the shares of our common stock could be highly volatile, and purchasers of our common stock could incur substantial losses.

All statements other than statements of historical facts contained in this Annual Report, including statements regarding our future results of operations and financial position, business strategy, research and development plans, the anticipated timing, costs, design, and conduct of our ongoing and planned preclinical studies and planned clinical trials for lorundrostat and any future product candidates, the timing and likelihood of regulatory filings and approvals for lorundrostat and any future product candidates, our ability to commercialize our product candidates, if approved, the potential to develop future product candidates, the potential benefits of strategic collaborations and our intent to enter into any strategic arrangements, the timing and likelihood of success, and plans and objectives of management for future operations and future results of anticipated product development efforts, 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.

Part I

Item 1. Business

Business Overview

We are a clinical-stage biopharmaceutical company focused on developing medicines to target diseases driven by abnormally elevated aldosterone. Our clinical-stage product candidate, lorundrostat, is a proprietary, orally administered, highly selective aldosterone synthase inhibitor (ASI) that we are initially developing for the treatment of cardiorenal conditions affected by abnormally elevated aldosterone, including hypertension and chronic kidney disease (CKD). In the United States, there are over 115 million patients who have sustained elevated blood pressure (BP), or hypertension, and more than half of this population fails to achieve their BP goals, defined as BP of below 130/80 mmHg, with currently available medications. There are over 30 million treated patients who do not achieve their BP goal, of whom approximately 20 million have systolic BP levels greater than 140 mmHg. Patients with hypertension that persists despite taking two or more medications have 1.8 and 2.5 times greater mortality risk due to either cardiovascular disease or stroke, respectively. In a Phase 2 proof-of-concept clinical trial evaluating 200 subjects (Target-HTN) with uncontrolled hypertension (uHTN), defined as individuals who are unable to achieve BP of below 130/80 mmHg despite taking two or more lines of antihypertensive medication, or resistant hypertension (rHTN), defined as individuals who are unable to achieve BP of below 130/80 mmHg despite taking three or more antihypertensive medications typically including a diuretic, lorundrostat demonstrated a clinically meaningful and statistically significant reduction in BP with once-daily dosing and was well tolerated. Abnormally elevated aldosterone levels are a key factor in driving hypertension in approximately 25% of hypertensive patients. In addition to hypertension, we intend to investigate the benefits of lorundrostat in subjects with hypertension and CKD. We believe that our product candidate holds promise to be an innovative solution for the rapidly growing unmet ne
