We caution you that the foregoing list may not include all of the forward-looking statements made in this Quarterly Report. Although management presently believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to be correct and you should be aware that actual results could differ materially from those contained in the statements.

Forward-looking statements are subject to a number of risks and uncertainties including, but not limited to: our clinical development of resmetirom; enrollment uncertainties, generally and in relation to and social distancing measures and individual precautionary measures that may be implemented or continued for an uncertain period of time; outcomes or trends from competitive studies; future topline data timing or results; the risks of achieving potential benefits in studies that includes substantially more patients than our prior studies; the timing and outcomes of clinical studies of resmetirom; and the uncertainties inherent in clinical testing. Undue reliance should not be placed on forward-looking statements, which speak only as of the date they are made. Madrigal undertakes no obligation to update any forward-looking statements to reflect new information, events or circumstances after the date they are made, or to reflect the occurrence of unanticipated events. Please refer to Madrigal’s submissions filed or furnished with the U.S. Securities and Exchange Commission for more detailed information regarding these risks and uncertainties and other factors that may cause actual results to differ materially from those expressed or implied. We specifically discuss these risks and uncertainties in greater detail in the section appearing in Part I, Item 1A of our Annual Report on Form for the year ended December 31, 2020, filed with the SEC on February 25, 2021, as well as in our other filings with the SEC. You should read the 2020 Annual Report on Form this Quarterly Report, and the other documents that we file or have

Except as required by applicable law or the rules of the NASDAQ Stock Market, or NASDAQ, we assume no obligation to update any forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these statements, even if new information becomes available in the future. We qualify all of our forward-looking statements by these cautionary statements.

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of innovative therapeutic candidates for the treatment of cardiovascular, metabolic, and liver diseases. Our lead product candidate, MGL-3196 (resmetirom), is a proprietary, selective thyroid hormone receptor-ß, or agonist being developed as a once-daily oral pill that can potentially be used to treat a number of disease states with high unmet medical need, including steatohepatitis, or NASH.

NASH is a serious inflammatory form of nonalcoholic fatty liver disease, or NAFLD. NAFLD has become the most common liver disease in the United States and other developed countries and is characterized by an accumulation of fat in the liver with no other apparent causes. NASH can progress to cirrhosis or liver failure, require liver transplantation and can also result in liver cancer. Progression of NASH to end stage liver disease will soon surpass all other causes of liver failure requiring liver transplantation. Importantly, beyond these critical conditions, NASH and NAFLD patients additionally suffer heightened cardiovascular risk and, in fact, die more frequently from cardiovascular events than from liver disease. NASH and NAFLD have grown as a consequence of rising worldwide obesity-related disorders. In 2016, in the United States alone, NAFLD was estimated to affect approximately 26% of the population, or an estimated 85 million people, and approximately 20% of this population was projected to progress from NAFLD to NASH. Current estimates place NASH prevalence at approximately 17 million people in the United States, or five percent of the population. Slightly lower prevalence is seen in the EU and Asia, with approximately of the population having NASH.

For NASH, we enrolled 125 patients in a Phase 2 clinical trial with resmetirom. We achieved the primary endpoint for this Phase 2 clinical trial and reported the results in December 2017, and we reported positive topline results at the conclusion of the Phase 2 clinical trial in May 2018. We also completed a open-label extension study in 31 participating NASH patients from our Phase 2 clinical trial, which included 14 patients who received placebo in the main study. We also completed a 116 patient Phase 2 clinical trial and announced results in February 2018 for the use of resmetirom in patients with heterozygous familial hypercholesterolemia, or HeFH. In addition to the NASH and HeFH Phase 2 clinical trials, resmetirom has also been studied in multiple completed Phase 1 trials in a total of more than 300 subjects. Resmetirom appeared to be safe and was well-tolerated in these trials, which included a single ascending dose trial, a multiple ascending dose trial, several drug interaction studies, a multiple dose mass balance study, a single dose relative bioavailability study of tablet formulation versus capsule formulation, a multiple dose drug interaction study, a multiple dose drug interaction with food effect study, and a hepatic impairment study.

On March 28, 2019, the Company announced that it had initiated MAESTRO-NASH, a Phase 3 trial in NASH with its once daily, oral thyroid hormone receptor beta selective agonist, resmetirom. This double-blind, placebo-controlled study is being conducted at more than 200 sites in the United States and the rest of the world. Patients with liver biopsy confirmed NASH with stage 2 or 3 fibrosis are being randomized 1:1:1 to receive a single oral daily dose of placebo, resmetirom 80 mg or resmetirom 100 mg. A second liver biopsy at week 52 in the first 900 patients will be the basis of filing for Subpart H-accelerated approval; the primary endpoint will be the percent of patients treated with either dose of resmetirom as compared with placebo who achieve NASH resolution on the week 52 liver biopsy, defined as the absence of hepatocyte ballooning (score=0), and minimal lobular inflammation (score associated with at least a reduction in NAS (NAFLD Activity Score), and no worsening of fibrosis stage. Two key secondary endpoints are reduction in and a or more improvement in fibrosis stage on the week 52 biopsy with no worsening of NASH. Patients will continue in the study for a total of approximately 54 months, and will be evaluated for a composite clinical outcome including cirrhosis on liver biopsy, or a liver related event such as hepatic decompensation. The total anticipated enrollment is approximately 2,000 patients, and will include up to 15% high risk F1 fibrosis stage NASH patients whose efficacy responses will be evaluated as exploratory

endpoints. On June 30, 2021 we announced our achievement of the requisite enrollment of patients to support the planned Subpart H (Accelerated Approval of New Drugs for Serious or Life-Threatening Illnesses) submission to the US Food and Drug Administration (FDA). On December 18, 2019 the Company announced it had opened for enrollment a multi-center, double-blind, placebo-controlled Phase 3 clinical study of patients with biopsy-confirmed or presumed NASH recruited from sites in the U.S. Key endpoints are safety, including safety biomarkers. Secondary endpoints include LDL cholesterol, lipid biomarkers, NASH and fibrosis biomarkers. Except for serial liver biopsies, the study protocol is similar to the MAESTRO-NASH study with resmetirom doses of 80 mg or 100 mg or placebo. In October 2020, we completed enrollment of the double-blind, arms of the study. Enrollment objectives for this study have been exceeded, with approximately 1,300 patients enrolled overall. The study will help support the adequacy of the safety database at the time of NDA submission for Subpart H approval for treatment of NASH in patients with F2 or F3 fibrosis (MAESTRO-NASH, NASH resolution surrogate endpoint). On July 13, 2021 we announced first patient dosed in a planned open label active treatment extension study of named Label Extension (OLE). The OLE study allows patients who complete to consent to 52 weeks of active treatment with resmetirom, making this treatment available to both patients who were assigned to placebo in MAESTRO-NAFLD-1 and patients who were on resmetirom in

In April 2020 we announced that in response to guidance from regulatory agencies, measures for at impacted sites have been put in place for our Phase 3 MAESTRO-NASH and studies, allowing both studies to continue without changes to the protocol. At a recently conducted Data Monitoring Committee (DMC) meeting it was recommended that Phase 3 studies proceed without modification. The pandemic had no material adverse impact on our operating results, study or liquidity for the period ended September 30, 2021 and year ended December 31, 2020, but it did introduce clinical trial and operational risks and uncertainties that are both general in nature and relate specifically to our MAESTRO-NASH study. These risks and uncertainties, which are beyond our control, are summarized in the section entitled “Risk Factors” in Part I, Item 1A of our Annual Report on Form for the year ended December 31, 2020, filed with the SEC on February 25, 2021.

General and administrative expenses consist primarily of salaries, benefits and stock-based compensation expenses for employees, management costs, costs associated with obtaining and maintaining our patent portfolio, professional fees for accounting, auditing, consulting and legal services, liability insurance, and allocated overhead expenses. We expect that our general and administrative expenses may increase in the future as we advance our clinical and preclinical development programs for resmetirom and expand our operating activities, including substantially expanding our workforce for commercial hires, and maintaining and expanding our patent portfolio. We expect these potential increases will likely include management and personnel costs, legal fees, accounting fees, directors’ and officers’ liability insurance premiums and expenses associated with investor relations.

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities as of the date of the financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued research and development expenses and stock-based compensation expense. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. There have been no material changes in our critical accounting policies and significant judgments and estimates during the nine months ended September 30, 2021, as compared to those disclosed in our Annual Report on Form for the fiscal year ended December 31, 2020 filed with the SEC on February 25, 2021.

As of September 30, 2021, we had cash, cash equivalents and marketable securities totaling $299.1 million compared to $284.1 million as of December 31, 2020, with the increase attributable to net proceeds of $151.2 million raised from the sale of 1,347,290 shares under our (ATM) sales agreements, partially offset by funding of operations. Our cash and investment balances are held in a variety of interest bearing instruments, including obligations of U.S. government agencies, U.S. Treasury debt securities, corporate debt securities and money market funds. Cash in excess of immediate requirements is invested in accordance with our investment policy with a view toward capital preservation and liquidity.

We anticipate continuing to incur operating losses for the foreseeable future. While our rate of cash usage will likely increase in the future, in particular to support our product development and clinical trial efforts, we believe our available cash resources as of September 30, 2021 will be sufficient to fund our operations past one year from the issuance of the financial statements contained herein, and this outlook takes into account circumstances that are currently reasonably foreseeable in connection with the pandemic. For a description of pandemic risks, including risks and uncertainties beyond our control, see Part I, Item 1A, “Risk Factors” on Form for the year ended December 31, 2020, filed with the SEC on February 25, 2021. Our future long-term liquidity requirements will be substantial and will depend on many factors. To meet future long-term liquidity requirements, we will need to and intend to raise additional capital to fund our operations, primarily through equity or debt financings. We regularly consider fundraising opportunities and may decide, from time to time, to raise capital based on various factors, including market conditions and our plans of operation. This includes, but is not limited to, the use of the $200 million sales agreement. Additional capital may not be available on terms acceptable to us, or at all. If adequate funds are not available, or if the terms of potential funding sources are unfavorable, our business and our ability to develop our product candidates would be harmed. Furthermore, any sales of additional equity securities may result in dilution to our stockholders, and any financing may include covenants that restrict our business.

Net cash used in operating activities was $135.9 million for the nine months ended September 30, 2021, compared to $102.6 million for the corresponding period in 2020. The use of cash in these periods resulted primarily from our losses from operations, as adjusted for charges for stock-based compensation, and changes in our working capital accounts.

No significant changes to contractual obligations and commitments occurred during the nine months ended September 30, 2021, as compared to those disclosed in our Annual Report on Form for the fiscal year ended December 31, 2020 filed with the SEC on February 25, 2021.

We do not have any off balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation
