NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization, Business, and Basis of Presentation

Organization and Business

Madrigal Pharmaceuticals, Inc. (the “Company” or “Madrigal”) is a biopharmaceutical company dedicated to transforming care for patients with nonalcoholic steatohepatitis (“NASH”), a serious liver disease that can lead to cirrhosis, liver failure and premature mortality. The Company's medication, Rezdiffra (resmetirom), is a once-daily, oral, liver-directed THR-β agonist designed to target key underlying causes of NASH. In March 2024, Rezdiffra became the first and only FDA-approved therapy for patients with NASH. Rezdiffra is indicated in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).

Basis of Presentation

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Accordingly, the unaudited condensed consolidated financial statements do not include all information and footnotes required by GAAP for complete annual financial statements. However, the Company believes that the disclosures included in these financial statements are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of such interim results. The interim results are not necessarily indicative of the results that the Company will have for the full year ending December 31, 2024 or any subsequent period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes to those statements for the year ended December 31, 2023.

2. Summary of Significant Accounting Policies

Principle of Consolidation

The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, and the reported amounts of revenues and expenses during the reporting periods. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits.

The primary objective of the Company’s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company’s cash is deposited in highly rated financial institutions in the United States. The Company invests in money market funds and high-grade, commercial paper and corporate bonds, which management believes are subject to minimal credit and market risk.

Marketable Securities

Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets.

8

The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion as a component of interest income, net. Realized gains and losses and declines in value, if any, that the Company judges to be the result of impairment or as a result of recognizing an allowance for credit losses on available-for-sale securities are reported as a component of interest income. To determine whether an impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three months ended March 31, 2024 and 2023, the Company determined it did not have any securities that were other-than-temporarily impaired.

Marketable securities are stated at fair value, including accrued interest, with their unrealized gains and losses included as a component of accumulated other comprehensive income or loss, which is a separate component of stockholders’ equity. The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method. During the three months ended March 31, 2024 and 2023, the Company did not have any realized gains or losses on marketable securities.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash equivalents and marketable securities, approximate their fair values. The fair value of the Company’s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2—observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3—unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability.

Financial assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third- party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs.

As of March 31, 2024, the Company’s financial assets valued based on Level 1 inputs consisted of cash and cash equivalents in a money market fund, its financial assets valued based on Level 2 inputs consisted of high-grade corporate and government agency bonds and commercial paper, and it had no financial assets valued based on Level 3 inputs. During the three months ended March 31, 2024 and 2023, the Company did not have any transfers of financial assets between Levels 1 and 2. As of March 31, 2024 and December 31, 2023, the Company did not have any financial liabilities that were recorded at fair value on a recurring basis on the balance sheet.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value, using actual cost, based on a first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels quarterly and writes down inventory subject to expiry or in excess of expected requirements, or that has a cost basis in excess of its expected net realizable value. These write downs are charged to cost of goods sold in the accompanying Consolidated Statements of Income.

The Company considered regulatory approval of its product candidate to be uncertain and product manufactured prior to regulatory approval could not have been sold unless regulatory approval was obtained. As such, the manufacturing costs incurred prior to regulatory approval were not capitalized as inventory, but were expensed as incurred as research and development expenses.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation),

9

costs for consultants, milestone payments under licensing agreements, and other costs associated with the Company’s preclinical and clinical programs. In particular, the Company has conducted safety studies in animals, optimized and implemented the manufacturing of its drug, and conducted clinical trials, all of which are considered research and development expenditures. Management uses significant judgment in estimating the amount of research and development costs recognized in each reporting period. Management analyzes and estimates the progress of its clinical trials, completion of milestone events per underlying agreements, invoices received and contracted costs when estimating the research and development costs to accrue in each reporting period. Actual results could differ from the Company’s estimates.

Patents

Costs to secure and defend patents are expensed as incurred and are classified as selling, general and administrative expense in the Company’s consolidated statements of operations.

Intangible Assets

Intangible assets with finite lives are amortized to cost of goods sold over their estimated useful lives using the straight-line method. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Stock-Based Compensation

The Company recognizes stock-based compensation expense based on the grant date fair value of stock options, restricted stock units, and other stock-based compensation awards granted to employees, officers, directors, and consultants. Awards that vest as the recipient provides service are expensed on a straight-line basis over the requisite service period.

The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company’s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary.

For other stock-based compensation awards granted to employees and directors that vest based on market conditions, such as the trading price of the Company’s common stock achieving or exceeding certain price targets, the Company uses a Monte Carlo simulation model to estimate the grant date fair value and recognize stock compensation expense over the derived service period. The Monte Carlo simulation model requires key inputs for risk-free interest rate, dividend yield, volatility, and expected life.

The assumptions used in computing the fair value of equity awards reflect the Company’s best estimates but involve uncertainties related to market and other conditions. Changes in any of these assumptions may materially affect the fair value of awards granted and the amount of stock-based compensation recognized.

Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets.

Income Taxes

The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company’s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the

10

years in which the differences are expected to reverse. The Company currently maintains a 100% valuation allowance on its deferred tax assets.

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company’s net loss and comprehensive loss.

Basic and Diluted Loss Per Common Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the three months ended March 31, 2024 and 2023, diluted net loss per share is the same as basic net loss per share because the inclusion of weighted average shares of common stock issuable upon the exercise of stock options and warrants or vesting of restricted stock units, and common stock issuable upon the conversion of preferred stock would be anti-dilutive. The following table summarizes outstanding securities not included in the computation of diluted net loss per common share, as their inclusion would be anti-dilutive:

	Outstanding at March 31,
	2024	2023
Common stock options	2,458,227	2,676,598
Restricted stock units	530,671	199,125
Performance-based restricted stock units	252,404	—
Preferred stock	2,369,797	2,369,797
Warrants	3,625,244	17,352

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for operating segments in the Company's annual and interim consolidated financial statements. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the disclosures required for income taxes in the Company's annual consolidated financial statements. The amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-09 on its financial statements.

3. Liquidity and Uncertainties

The Company is subject to risks common to development stage companies and early commercial companies in the biopharmaceutical industry including, but not limited to, uncertainty of product development and commercialization, dependence on key personnel, uncertainty of market acceptance of products and product reimbursement, product liability, uncertain protection of proprietary technology, potential inability to raise additional financing necessary for development and commercialization, and compliance with the U.S. Food and Drug Administration (“FDA”) and other government regulations.

The Company has incurred losses since inception, including approximately $147.5 million for the three months ended March 31, 2024, resulting in an accumulated deficit of approximately $1,483.8 million as of March 31, 2024. To date, the Company has funded its operations primarily through proceeds from sales of the Company’s capital stock and debt financings. In March 2024, the FDA approved Rezdiffra in the U.S. for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Rezdiffra became available in the U.S. in April 2024. In March 2024, the Company completed a public offering and received approximately $574.0 million net cash proceeds. In April 2024, underwriters exercised in full their option to purchase additional shares as part of the public offering, resulting in additional net cash proceeds of approximately $85.9 million. Please see “Note 11 – Subsequent Events” to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for

11

more information. The Company believes that its cash, cash equivalents and marketable securities will be sufficient to fund operations past one year from the issuance of these financial statements. The Company’s future long-term liquidity requirements will be substantial and will depend on many factors, including the Company’s ability to effectively commercialize Rezdiffra. To meet its future capital needs, the Company may need to raise additional capital through debt or equity financings, collaborations, partnerships or other strategic transactions. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise. The inability of the Company to obtain sufficient funds on acceptable terms when needed, if at all, could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company has the ability to delay certain research activities and related clinical expenses if necessary due to liquidity concerns until a date when those concerns are relieved.

4. Cash, Cash Equivalents and Marketable Securities

The Company held restricted cash of $1.2 million as of March 31, 2024 as collateral to its corporate credit card program. The Company had no restricted cash as of December 31, 2023. Restricted cash is included within the cash and cash equivalents balance on the Consolidated Balance Sheet.

A summary of cash, cash equivalents and available-for-sale marketable securities held by the Company as of March 31, 2024 and December 31, 2023 is as follows (in thousands):

7. Long Term Debt

In May 2022 the Company and its wholly-owned subsidiary, Canticle Pharmaceuticals, Inc., entered into the $250.0 million Loan Facility with the several banks and other financial institutions or entities party thereto (each, a “Lender” and collectively referred to as the “Lenders”), and Hercules Capital, Inc. (“Hercules”), in its capacity as administrative agent and collateral agent for itself and the Lenders. Under the terms of the Loan Facility, the first $50.0 million tranche was drawn at closing. The Company also could draw up to an additional $125.0 million in two separate tranches upon achievement of certain resmetirom clinical and regulatory milestones. A fourth tranche of $75.0 million could have been drawn by the Company, subject to the approval of Hercules. The Loan Facility had a minimum interest rate of 7.45% and adjusted with changes in the prime rate. The Company was originally scheduled to pay interest-only monthly payments of accrued interest under the Loan Facility through May 1, 2025, for a period of 36 months. In March 2024, the interest-only period was extended to May 1, 2026 when the Company achieved a milestone when Rezdiffra received FDA approval. The interest only period can further be extended to May 3, 2027, upon the achievement of future revenue milestones, subject to compliance with applicable covenants. The Loan Facility originally matured in May 2026, but the maturity date was extended to May 2027 when the Company achieved a milestone upon receipt of FDA approval in March 2024. The Loan Facility is secured by a security interest in substantially all of the Company’s assets, other than intellectual property. It includes an end of term charge of 5.35% of the aggregate principal amount, which is accounted for in the loan discount. In connection with the first tranche drawn at closing, the Company issued Hercules a warrant to purchase 14,899 shares of Company common stock, which had a Black-Scholes value of $0.6 million.

On February 3, 2023, the Company entered into the First Amendment (the “Amendment”) to the Loan Facility (as amended, the “Amended Loan Facility”). Under the Amended Loan Facility, an additional $35.0 million was drawn under a second, expanded, $65.0 million tranche (“Tranche 2”) in February of 2023 following the Company’s achievement of the Phase 3 clinical development milestone. An additional $15.0 million was drawn under Tranche 2 in June of 2023. The remaining $15.0 million available under Tranche 2 was drawn in September of 2023 in accordance with the Amended Loan Facility. The third tranche (“Tranche 3”) of $75.0 million remains unchanged by the Amendment, and such borrowings became available when the Company achieved a milestone with FDA approval for Rezdiffra in March 2024. As of March 31, 2024, the Company has not drawn down on Tranche 3, and the $75.0 million remains available until June 12, 2024. Coincident with the expansion of Tranche 2 borrowing capacity by $15.0 million, the Amendment reduced the fourth tranche under the Loan Facility (“Tranche 4”) by $15.0 million to $60.0 million, which is available subject to Hercules’ sole discretion. In connection with the $35.0 million drawn under Tranche 2 at the closing of the Amendment, $15.0 million drawn in June of 2023, and $15.0 million drawn in September of 2023, the Company issued to Hercules and

13

affiliates Tranche 2 Warrants to purchase an aggregate of 4,555 shares of common stock, which had a Black-Scholes value of $0.9 million. The Amendment reduced the interest rate under the Amended Loan Facility to the greater of (i) the prime rate as reported in The Wall Street Journal plus 2.45% and (ii) 8.25%. The Amendment and the Amended Loan Facility summary terms were disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on February 9, 2023.

The Loan Facility includes affirmative and restrictive financial covenants commencing on January 1, 2023, including maintenance of a minimum cash, cash equivalents and liquid funds covenant of $35.0 million, which may decrease in certain circumstances if the Company achieves certain clinical milestones and a revenue milestone, and a revenue-based covenant that could apply commencing at or after the time that financial reporting is due for the quarter ending September 30, 2024. The Loan Facility contains event of default provisions for: the Company’s failure to make required payments or maintain compliance with covenants under the Loan Facility; the Company’s breach of certain representations or default under certain obligations outside the Loan Facility; insolvency, attachment or judgment events affecting the Company; and any circumstance which has occurred or could reasonably be expected to have a material adverse effect on the Company, provided that, any failure to achieve a clinical milestone or approval milestone under the Loan Facility shall not in and of itself constitute a material adverse effect. The Loan Facility also includes customary covenants associated with a secured loan facility, including covenants concerning financial reporting obligations, and certain limitations on indebtedness, liens (including a negative pledge on intellectual property and other assets), investments, distributions (including dividends), collateral, investments, distributions, transfers, mergers or acquisitions, taxes, corporate changes, and deposit accounts.

As of March 31, 2024, the outstanding principal under the Loan Facility was $115.0 million. The interest rate as of March 31, 2024 was 10.95%. As of March 31, 2024, the Company was in compliance with all loan covenants and provisions.

Future minimum payments, including interest and principal, under the loans payable outstanding as of March 31, 2024 are as follows (in thousands):

Period Ending March 31, 2024:	Amount
2024	$	9,619

Subject to the terms and conditions of the 2021 Sales Agreement, Cowen would use commercially reasonable efforts consistent with its normal trading and sales practices to sell the common stock based upon the Company’s instructions (including any price, time or size limits or other customary parameters or conditions the Company imposed).

9. Stock-based Compensation

2015 Stock Plan

The Company’s 2015 Stock Plan, as amended (the “2015 Stock Plan”), is one of the Company’s equity incentive compensation plans through which equity based grants are awarded.

Our operating results are not necessarily indicative of results that may occur for the full fiscal year or any other future period. As used herein, “Rezdiffra” refers to resmetirom approved by the FDA for the treatment of adults with NASH with moderate to advanced liver fibrosis, and “resmetirom” refers to, where applicable, Rezdiffra as well as resmetirom for the treatment of indications beyond NASH with moderate to advanced liver fibrosis.

About Madrigal Pharmaceuticals, Inc.

We are a biopharmaceutical company dedicated to transforming care for patients with NASH, a serious liver disease that can lead to cirrhosis, liver failure and premature mortality. Our medication, Rezdiffra (resmetirom), is a once-daily, oral, liver-directed THR-β agonist designed to target key underlying causes of NASH. In March 2024, Rezdiffra became the first and only FDA-approved therapy for patients with NASH. Rezdiffra is indicated in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).

NASH Disease State Overview. NASH is a more advanced form of nonalcoholic fatty liver disease (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. NASH is the leading cause of liver transplants in the U.S. for women, and is expected to soon be the leading cause of liver transplants overall. Additionally, patients with NASH, especially those with more advanced metabolic risk factors (hypertension, concomitant type 2 diabetes), are at increased risk for adverse cardiovascular events and increased morbidity and mortality. Once patients progress to NASH with moderate to advanced fibrosis (consistent with fibrosis stages F2 and F3), the risk of adverse liver outcomes increases substantially.

NASH is also known as metabolic dysfunction-associated steatohepatitis (“MASH”) following a change in disease nomenclature introduced by hepatology medical societies in 2023.

Our Patient Focus. Madrigal estimates that approximately 1.5 million patients have been diagnosed with NASH in the U.S., of which approximately 525,000 have NASH with moderate to advanced fibrosis. Madrigal estimates that approximately 315,000 diagnosed patients with NASH with moderate to advanced fibrosis are under the care of specialist physicians Madrigal will be targeting during the launch of Rezdiffra.

Our Clinical Development Program. Madrigal is currently conducting multiple Phase 3 clinical trials to evaluate the safety and efficacy of Rezdiffra for the treatment of NASH, including the pivotal MAESTRO-NASH biopsy study in patients with significant fibrosis, the MAESTRO-NASH Outcomes study in patients with NASH with compensated cirrhosis and the MAESTRO-NAFLD-1 OLE safety study. Positive results from the pivotal MAESTRO-NASH biopsy study were published in the New England Journal of Medicine in February 2024.

Data from the 52-week first 1,000 patient portion of MAESTRO-NASH, together with data from MAESTRO-NAFLD-1, the open-label extension of the MAESTRO-NAFLD-1 study, Phase 2 and Phase 1 data, including safety parameters, formed the basis for Madrigal’s successful subpart H submission to the FDA for accelerated approval of Rezdiffra for treatment of NASH with liver fibrosis.

Key Developments

On March 18, 2024, we announced we had commenced an underwritten public offering of $500.0 million in shares of our common stock and pre-funded warrants to purchase shares of our common stock. The size of the offering was

23

increased by $100.0 million subsequent to the initial announcement, for a total of approximately $600.0 million gross proceeds before underwriting discounts, commissions, and other expenses. The $600.0 million offering closed on March 21, 2024, and we received net proceeds totaling approximately$574.0 million in the three months ended March, 31, 2024. The underwriters exercised in full their 30-day option to purchase additional shares of common stock, resulting in an additional $90.0 million gross proceeds. The exercise of the underwriters' option closed on April 2, 2024 and we received net proceeds totaling approximately $85.9 million. We collectively sold an aggregate of 1,096,153 shares of our common stock and pre-funded warrants to purchase 1,557,692 shares of our common stock in the underwritten offering.

On March 14, 2024, we announced that the U.S. Food and Drug Administration (“FDA”) granted accelerated approval of Rezdiffra (resmetirom) in conjunction with diet and exercise for the treatment of adults with noncirrhotic nonalcoholic steatohepatitis (“NASH”) with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).

On February 28, 2024, we announced the appointment of Mardi C. Dier as Chief Financial Officer, effective as of March 11, 2024.

In February 2024, primary results from the MAESTRO-NASH study were published in the New England Journal of Medicine.

Basis of Presentation

Research and Development Expenses

Research and development expenses primarily consist of costs associated with our research activities, including the preclinical and clinical development of our product candidates. We expense our research and development expenses as incurred. We contract with clinical research organizations to manage our clinical trials under agreed upon budgets for each study, with oversight by our clinical program managers. We account for nonrefundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received. Manufacturing expense includes costs associated with drug formulation development and clinical drug production. We do not track employee and facility related research and development costs by project, as we typically use our employee and infrastructure resources across multiple research and development programs. We believe that the allocation of such costs would be arbitrary and not be meaningful.

Our research and development expenses consist primarily of:

•salaries and related expense, including stock-based compensation;

•external expenses paid to clinical trial sites, contract research organizations, laboratories, database software and consultants that conduct clinical trials;

•expenses related to development and the production of nonclinical and clinical trial supplies, including fees paid to contract manufacturers;

•expenses related to preclinical studies;

•expenses related to compliance with drug development regulatory requirements; and

•other allocated expenses, which include direct and allocated expenses for depreciation of equipment and other supplies.

We expect to continue to incur substantial expenses related to our development activities for the foreseeable future as we conduct our clinical studies programs, manufacturing and toxicology studies. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials, additional drug manufacturing requirements, and later stage toxicology studies such as carcinogenicity studies. The process of conducting preclinical studies and clinical trials necessary to obtain regulatory approval is costly and time consuming. The probability of success for each product candidate is affected by numerous factors, including preclinical data, clinical data, competition, manufacturing capability and commercial viability.

Completion dates and costs for our clinical development programs as well as our research program can vary significantly for each current and future product candidate and are difficult to predict. As a result, we cannot estimate with any degree of certainty the costs we will incur in connection with the development of our product candidates at this point in time. We expect that we will make determinations as to which programs and product candidates to pursue and how much funding to direct to each program and product candidate on an ongoing basis in response to the scientific success of research, results of ongoing and future clinical trials, potential collaborative agreements with respect to programs or

24

potential product candidates, as well as ongoing assessments as to each current or future product candidate’s commercial potential.

Selling, General and Administrative Expenses

Selling, 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, and allocated overhead expenses.

We expect that our selling, general and administrative expenses will increase in the future as we expand our operating activities, prepare for commercialization, maintain and expand our patent portfolio and incur additional costs associated with being a public company and maintaining compliance with exchange listing and SEC requirements. We expect these potential increases will likely include management costs, legal fees, accounting fees, directors’ and officers’ liability insurance premiums and expenses associated with investor relations.

Critical Accounting Policies and Estimates

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 three months ended March 31, 2024, as compared to those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 28, 2024.

Research and Development Expenses

The following table represents our research and development expenses for the three months ended March 31, 2024 and 2023 (in thousands):

	Three Months Ended March 31,				Increase / Decrease
	2024		2023		$		%
Personnel and Internal Expense	$	16,716	$	12,259	$	4,457	36	%
External Expense	54,521		49,895		4,626		9	%
Total	$	71,237	$	62,154	$	9,083	15	%

Our research and development expenses were $71.2 million for the three months ended March 31, 2024, compared to $62.2 million in the corresponding period in 2023. Research and development expenses increased by $9.1 million in the 2024 period due primarily to an increase related to timing of manufacturing, an increase in headcount, and a corresponding increase in stock compensation expense.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses were $80.8 million for the three months ended March 31, 2024, compared to $16.2 million in the corresponding period in 2023. Selling, general and administrative expenses increased by $64.6 million in the 2024 period due primarily to increases in commercial preparation activities, including a corresponding increase in headcount, and an increase in stock compensation expense. We believe our selling, general and administrative expenses may increase over time as we continue with commercialization activities and expand our operating activities.

Interest Income

Our net interest income was $8.3 million for the three months ended March 31, 2024, compared to $3.8 million in the corresponding period in 2023. The increase in interest income was due primarily to higher principal balances and interest rates in 2024.

Interest Expense

Our interest expense was $3.8 million for the three months ended March 31, 2024, compared to $2.3 million in the corresponding period in 2023. The increase in interest expense was primarily the result of a higher outstanding principal balance during the period under the Loan Facility with Hercules.

Liquidity and Capital Resources

Since inception, we have incurred significant net losses and we have funded our operations primarily through the issuance of shares of our common stock, shares of our Preferred Stock, issuances of pre-funded warrants, borrowings under the Loan Facility with Hercules, the issuance of convertible debt and the proceeds from the merger with Synta Pharmaceuticals Corp. Our most significant use of capital pertains to salaries and benefits for our employees, including clinical, scientific, operational, financial and management personnel, and external research and development expenses, such as clinical trials and preclinical activity related to our product candidates.

As of March 31, 2024, we had cash, cash equivalents and marketable securities totaling $1,059.1 million compared to $634.1 million as of December 31, 2023, with this increase attributable to our 2024 public offering, where we received net proceeds of approximately $574.0 million in the three months ended March 31, 2024. Additionally, in April 2024 we received net proceeds of approximately $85.9 million as a result of the underwriters’ exercise in full of their option to purchase additional shares as part of the March 2024 Offering. 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.

While our rate of cash usage will likely increase in the future, in particular to support our product development and clinical trial efforts, as well as commercialization activities, we believe our available cash resources are sufficient to fund our operations past one year from the issuance of the financial statements contained herein. Our future long-term liquidity requirements will be substantial and will depend on many factors, including our ability to effectively

26

commercialize Rezdiffra. To meet future long-term liquidity requirements, as well as maintain compliance with certain of our Loan Facility covenants, we may need to raise additional capital to fund our operations through equity or debt financings, collaborations, partnerships or other strategic transactions. 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. Additional capital, if needed, may not be available on terms acceptable to us, or at all. We also have the ability to delay certain research activities and related clinical expenses, as well as commercial investments, if necessary due to liquidity concerns until a date when those concerns are relieved. 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 debt financing may include covenants that restrict our business.

At-the-Market Sales Agreement

On May 9, 2023, the Company entered into Amendment No. 1 (the “Sales Agreement Amendment”) to the June 2021 Sales Agreement (the “2021 Sales Agreement”) with Cowen, which the Sales Agreement Amendment increased by up to an additional $200.0 million the amount of common stock that can be issued and sold by the Company from time to time through or to Cowen under the 2021 Sales Agreement, acting as agent or principal.

Sales of our common stock, if any, under the Sales Agreement will be made by any method that is deemed to be an “at the market” offering as defined in Rule 415(a)(4) of the Securities Act of 1933, as amended. We have no obligation to sell any common stock and may at any time suspend offers under the Sales Agreement or terminate the Sales Agreement pursuant to its terms.

During the three months ended March 31, 2024, under the Sales Agreement Amendment, we sold no shares. As of March 31, 2024, $174.8 million remained reserved and available for sale under the 2023 Sales Agreement Amendment and our related prospectus supplement.

Loan Facility

In May 2022 we entered into the $250.0 million Loan Facility (the “Loan Facility”) with Hercules Capital, Inc. (“Hercules”). On February 3, 2023, we entered into the First Amendment (the “Amendment”) to the Loan Facility (as amended, the “Amended Loan Facility”). Under the terms of the Loan Facility, the first $50.0 million tranche (“Tranche 1”) was drawn at closing. Under the Amended Loan Facility, $65.0 million was drawn in 2023 under the second tranche (“Tranche 2”). The third tranche (“Tranche 3”) of $75.0 million became available to us when we obtained FDA approval for Rezdiffra in March 2024. We have until June 12, 2024 to draw on Tranche 3. As of March 31, 2024, we have not drawn down on Tranche 3. The fourth tranche (“Tranche 4”) of $60.0 million is available subject to Hercules’ sole discretion. In connection with Tranche 1, in 2022 we issued Hercules warrants to purchase 14,899 shares of our common stock, which had a Black-Scholes value of $0.6 million. In connection with Tranche 2, in 2023 we issued to Hercules warrants to purchase an aggregate of 4,555 shares of common stock, which had a Black-Scholes value of $0.9 million.

The Loan Facility had a minimum interest rate of 7.45% and adjusted with changes in the prime rate. The Amendment reduced the interest rate under the Amended Loan Facility to the greater of (i) the prime rate as reported in The Wall Street Journal plus 2.45% and (ii) 8.25%. We were to originally pay interest-only monthly payments of accrued interest under the Loan Facility through May 1, 2025, for a period of 36 months. That period was extended in March 2024 to May 1, 2026 upon achievement of a milestone related to FDA approval. The period can further be extended to May 3, 2027, upon the achievement of a future revenue milestone, subject to compliance with applicable covenants. The Loan Facility originally matured in May 2026, but was extended to May 2027 upon the achievement a milestone related to FDA approval. The Loan Facility is secured by a security interest in substantially all of our assets, other than intellectual property. It includes an end of term charge of 5.35% of the aggregate principal amount, which is accounted for in the loan discount.

The Loan Facility includes affirmative and restrictive financial covenants which commenced on January 1, 2023, including maintenance of a minimum cash, cash equivalents and liquid funds covenant of $35.0 million, which may decrease in certain circumstances if we achieve certain clinical milestones and a revenue milestone, and a revenue-based covenant that could apply commencing at or after the time that financial reporting is due for the quarter ending September 30, 2024. The Loan Facility contains event of default provisions for: our failure to make required payments or maintain compliance with covenants under the Loan Facility; our breach of certain representations or default under certain obligations outside the Loan Facility; insolvency, attachment or judgment events affecting us; and any circumstance which has occurred or could reasonably be expected to have a material adverse effect on us, provided that, any failure to achieve approval or certain other milestones under the Loan Facility shall not in and of itself constitute a material adverse effect.

27

The Loan Facility also includes customary covenants associated with a secured loan facility, including covenants concerning financial reporting obligations, and certain limitations on indebtedness, liens (including a negative pledge on intellectual property and other assets), investments, distributions (including dividends), collateral, investments, distributions, transfers, mergers or acquisitions, taxes, corporate changes, and deposit accounts.

As of March 31, 2024, the outstanding principal under the Loan Facility was $115.0 million. The interest rate as of March 31, 2024 was 10.95%. As of March 31, 2024, we were in compliance with all loan covenants and provisions.

March 2024 Public Offering

On March 18, 2024, we entered into an Underwriting Agreement with Goldman Sachs & Co. LLC, Jefferies LLC, Cowen and Company, LLC, Evercore Group L.L.C. and Piper Sandler & Co, as representatives of the several underwriters named therein (the “2024 Underwriters”), pursuant to which we sold to the 2024 Underwriters in an underwritten public offering (the “2024 Offering”): (i) 750,000 shares of common stock at a public offering price of $260.00 per share, (ii) pre-funded warrants (the “2024 Pre-Funded Warrants”) to purchase 1,557,692 shares of common stock at a public offering price of $259.9999 per 2024 Pre-Funded Warrant, which represents the per share public offering price for the common stock less a $0.0001 per share exercise price for each such Pre-Funded Warrant, and (iii) a 30-day option for the 2024 Underwriters to purchase up to 346,153 additional shares of common stock at the public offering price of $260.00 per share (the “Underwriters’ Option”). The 2024 Offering closed on March 21, 2024.

The gross proceeds of the 2024 Offering was $600.0 million, and we received net proceeds, after deducting the underwriting discount and commissions and other estimated offering expenses payable by us, of approximately $574.0 million.

The Underwriters’ Option was later exercised in full, and closed on April 2, 2024. We received net proceeds for the exercise of the Underwriters’ Option, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, of approximately $85.9 million.

We intend to use the net proceeds from the 2024 Offering for our commercial activities in connection with the launch of Rezdiffra in the U.S. and for general corporate purposes, including, without limitation, research and development expenditures, ongoing clinical trial expenditures, manufacture and supply of drug substance and drug products, potential ex-U.S. commercialization or partnering opportunities, potential acquisitions or licensing of new technologies, capital expenditures and working capital.

The 2024 Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of 2024 Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of 2024 Pre-Funded Warrants may increase or decrease this percentage, but not in excess of 19.99%, by providing at least 61 days prior notice to the Company.

2023 Public Offering

On September 28, 2023, we entered into an Underwriting Agreement with Goldman Sachs & Co. LLC, as representative of the several underwriters named therein, pursuant to which we sold to the underwriters in an underwritten public offering (the “2023 Offering”): (i) 1,248,098 shares of common stock at a public offering price of $151.69 per share, and (ii) pre-funded warrants (the “2023 Pre-Funded Warrants”) to purchase 2,048,098 shares of common stock at a public offering price of $151.6899 per 2023 Pre-Funded Warrant, which represents the per share public offering price for the common stock less a $0.0001 per share exercise price for each such 2023 Pre-Funded Warrant. The 2023 Offering closed on October 3, 2023.

The gross proceeds of the 2023 Offering was $500.0 million, and we received net proceeds, after deducting the underwriting discount and commissions and other estimated offering expenses payable by us, of approximately $472.0 million. We intend to use the net proceeds from the 2023 Offering for our clinical and commercial activities for the launch of resmetirom in the U.S. and for general corporate purposes, including, without limitation, research and development expenditures, clinical trial expenditures, manufacture and supply of drug substance and drug products, potential acquisitions or licensing of new technologies, capital expenditures and working capital.

The 2023 Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of 2023 Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of

28

2023 Pre-Funded Warrants may increase or decrease this percentage, but not in excess of 19.99%, by providing at least 61 days prior notice to us.

Cash Flows

The following table provides a summary of our net cash flow activity (in thousands):

	Three Months Ended March 31,
	2024		2023
Net cash used in operating activities	$	(149,157)	$	(84,067)
Net cash provided by (used in) investing activities	98,053		(186,864)
Net cash provided by financing activities	573,706		52,690
Net increase (decrease) in cash, cash equivalents, and restricted cash	$	522,602	$	(218,241)

Net cash used in operating activities was $149.2 million for the three months ended March 31, 2024, compared to $84.1 million for the corresponding period in 2023. The use of cash in these periods resulted primarily from our losses from operations, as adjusted for non-cash charges for stock-based compensation, and changes in our working capital accounts.

Net cash provided by investing activities was $98.1 million for the three months ended March 31, 2024, compared to $186.9 million used in for the corresponding period in 2023. Net cash provided by investing activities for the three months ended March 31, 2024 primarily consisted of $182.6 million from sales and maturities of marketable securities, partially offset by $84.2 million of purchases of marketable securities for our investment portfolio. Net cash used in investing activities for the corresponding period in 2023 primarily consisted of $198.8 million of purchases of marketable securities for our investment portfolio, partially offset by $12.0 million from sales and maturities of marketable securities.

Net cash provided by financing activities was $573.7 million for the three months ended March 31, 2024, compared to $52.7 million for the corresponding period in 2023. Financing activities for the three months ended March 31, 2024 consisted of $574.0 million of proceeds from our March 2024 public offering. Net cash provided by financing activities for the corresponding period in 2023 consisted primarily of $35.0 million from issuance of the Loan Facility and $17.9 million from proceeds from the exercise of common stock options.

Contractual Obligations and Commitments

In August 2023, we entered into the Fifth Amendment to our Office Lease (the “Lease Amendment”). The Lease Amendment extends the term of the lease through November 2026. As a result of the Lease Amendment, an incremental $1.6 million million ROU asset and lease liabilities were recorded during the year ended December 31, 2023.

In May 2022 we entered into the $250.0 million Loan Facility. As of March 31, 2024, we had drawn $115.0 million under the facility. We are scheduled to pay interest-only monthly payments of accrued interest under the Loan Facility through May 1, 2026, which period may be extended to May 3, 2027 upon the achievement of future revenue milestones, and subject to compliance with applicable covenants.

We have a Research, Development and Commercialization Agreement with Hoffmann-La Roche (“Roche”) which grants the Company a sole and exclusive license to develop, use, sell, offer for sale and import any Licensed Product as defined by the agreement. We received FDA approval for Rezdiffra in March 2024. A tiered single-digit royalty is payable to Roche on net sales of Rezdiffra, subject to certain reductions.

Except as noted above and the future minimum payments due on the Loan Facility with Hercules set forth in “Note 7 – Long Term Debt” to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, no significant changes to contractual obligations and commitments occurred during the three months ended March 31, 2024, as compared to those disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 filed with the SEC on February 28, 2024.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

Our exposure to market risk is confined to our cash, cash equivalents and marketable securities and Loan Facility. We regularly review our investments and monitor the financial markets. We invest in high-quality financial instruments, primarily money market funds, U.S. government and agency securities, government- sponsored bond obligations and certain other corporate debt securities, with the effective duration of the portfolio less than twelve months and no security with a duration in excess of twenty-four months, which we believe are subject to limited credit risk. We currently do not hedge interest rate exposure. Due to the short-term duration of our investment portfolio and the current risk profile of our investments, we believe that an immediate 10% change in interest rates would not have a material effect on the fair market value of our portfolio. We do not believe that we have any material exposure to interest rate risk or changes in credit ratings arising from our investments.

In May 2022 we entered into the Loan Facility, which has an interest rate that is linked to the prime rate. We do not believe that we have any material exposure to interest rate risk given the current principal amount of the loan.

Capital Market Risk

As of March 31, 2024, we have no product revenue and have historically depended on funds raised through other sources. One source of funding is through future debt or equity offerings. Our ability to raise funds in this manner depends upon, among other things, capital market forces affecting our stock price.

Effects of Inflation

We do not believe inflation has had a material effect on our business, financial condition or results of operations during three months ended March 31, 2024 and March 31, 2023, respectively.

Item 4.    Controls and Procedures.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision of our principal executive officer and principal financial officer, we evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. Based on that

evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2024.

Limitations on the Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.    Legal Proceedings.

We are not party to any material legal proceedings.

Item 1A.    Risk Factors.

Except as set forth below, there have been no material changes to the risk factors included in detail in the “Risk Factors” sections appearing in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 28, 2024 (the “Annual Report”)

In order to execute our business plan and achieve profitability, we need to effectively commercialize Rezdiffra, which received FDA approval in March 2024 for the treatment of adults with NASH with moderate to advanced liver fibrosis. We may not be able to meet expectations with respect to sales of Rezdiffra or attain profitability and positive cash-flow from operations.

Rezdiffra is our only drug that has been approved for sale and it has been approved only for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis in the United States. We are focusing a significant portion of our activities and resources on Rezdiffra, and we believe our prospects are highly dependent on, and a significant portion of the value of our company relates to, our ability to successfully commercialize Rezdiffra for the treatment of adults with NASH with moderate to advanced liver fibrosis in the United States.

Successful commercialization of Rezdiffra is subject to many risks. We have never, as an organization, launched or commercialized any product, and there is no guarantee that we will be able to successfully commercialize Rezdiffra for its approved indication. There are numerous examples of failures to meet high expectations of market potential, including by pharmaceutical companies with more experience and resources than us. We are in the process of building our commercial organization and hiring our U.S. sales force and will need to refine and further develop our commercial organization in order to successfully commercialize Rezdiffra. We expect that the initial commercial success of Rezdiffra for the treatment of NASH will depend on many factors, including the following:

•the efficacy, cost, approved use, and side-effect profile of Rezdiffra regimens relative to competitive treatment regimens for the treatment of NASH;

•Rezdiffra may compete with the off-label use of currently marketed products and other therapies in development that may in the future obtain approval for NASH;

•the effectiveness of our commercial strategy for the marketing of Rezdiffra, including our pricing strategy and the effectiveness of our efforts to obtain adequate third-party reimbursements;

•developing, maintaining and successfully monitoring commercial manufacturing arrangements for Rezdiffra with third-party manufacturers to ensure they meet our standards and those of regulatory authorities, including the FDA, which extensively regulate and monitor pharmaceutical manufacturing facilities;

•our ability to negotiate and enter into any additional commercial, supply and distribution contracts to support commercialization efforts, and to hire and manage additional qualified personnel;

•our ability to meet the demand for commercial supplies of Rezdiffra at acceptable costs;

•the acceptance of Rezdiffra by physicians, patients and third-party payors;

•our ability to remain compliant with laws and regulations that apply to us and our commercial activities;

•the actual market-size, ability to identify targeted patients and the demographics of patients eligible for Rezdiffra, which may be different than what we currently expect;

•the occurrence of any side effects, adverse reactions or misuse, or any unfavorable publicity in these areas;

•our ability to obtain, maintain or enforce our patents and other intellectual property rights; and

•the effect of recent or potential health care legislation in the United States.

While we believe that Rezdiffra for the treatment of NASH should have a commercially competitive profile, we cannot accurately predict the amount of time needed to attain a commercially successful profile or the amount of revenue that would be generated from the sale of Rezdiffra. If we do not effectively commercialize Rezdiffra, we will not be able to execute our business plan and may not be able to achieve profitability. If our revenues, market share and/or other indicators

31

of market acceptance of Rezdiffra do not meet the expectations of investors or public market analysts, the market price of our common stock would likely decline.

Rezdiffra has received accelerated approval from the FDA, and therefore faces future post-approval development and regulatory requirements, which present additional challenges for us to successfully navigate.

The FDA granted accelerated approval of Rezdiffra for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis in the United States in March 2024. Under the accelerated approval pathway, continued approval may be contingent upon verification of a clinical benefit in confirmatory trials. These post- approval requirements and commitments may not be feasible and/or could impose significant burdens and costs on us; could negatively impact our development, manufacturing and supply of our products; and could negatively impact our financial results. Drugs granted accelerated approval must meet the same statutory standards for safety and effectiveness as those granted traditional approval. Failure to meet post-approval commitments and requirements, including completion of enrollment of—and in particular, any failure to obtain positive data from—any confirmatory studies required by the FDA, could result in negative regulatory action from the FDA and/or withdrawal of such accelerated approval. The recently enacted Food and Drug Omnibus Reform Act has expanded FDA’s expedited withdrawal procedures for drugs approved through the accelerated approval pathway if a sponsor fails to conduct any required post-approval study with due diligence.

Unless otherwise informed by the FDA, an applicant must submit to the FDA for consideration during the preapproval review period copies of all promotional materials, including promotional labeling as well as advertisements, intended for dissemination or publication within 120 days following marketing approval. After 120 days following marketing approval, unless otherwise informed by the FDA, the applicant must submit promotional materials at least 30 days prior to the intended time of initial dissemination of the labeling or initial publication of the advertisement. If we or the manufacturing facilities for our products fail to comply with applicable regulatory requirements, the FDA may, among other actions: issue warning letters or untitled letters; seek an injunction or impose civil or criminal penalties or monetary fines; suspend or withdraw or alter the conditions of our marketing approval; suspend any ongoing clinical trials; refuse to approve pending applications or supplements to applications submitted by us; suspend or impose restrictions on operations, including costly new manufacturing requirements; and seize or detain products, refuse to permit the import or export of products or require us to initiate a product recall.

[*personally identifiable information*]

Dear Carole:

This letter is to confirm our understanding with respect to (i) your agreement not to compete

with Madrigal Pharmaceuticals, Inc. or its current or future subsidiaries or Affiliates (collectively, the “Company”), (ii) your agreement to protect and preserve information and property which is confidential and proprietary to the Company and your agreement concerning Company Inventions specified herein (with the terms and conditions agreed to in this letter being referred to as the “Agreement”). For these purposes, an “Affiliate” is a person or entity that controls, is controlled by or is under common control with the Company, with “control” meaning the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person or entity, whether through the ownership of voting securities, by contract, or otherwise. You hereby acknowledge and agree that you are an “at-will” employee and that no provision of this Agreement shall be construed to create an express or implied employment contract, or a promise of employment for a specific period of time, and the Company expressly reserves the right to end your employment at any time, with or without notice or cause.

In consideration of your employment by the Company, the mutual promises and covenants contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby mutually acknowledged, we have agreed as follows:

1.Prohibited Competition and Solicitation.

(a)     Certain Acknowledgments and Agreements.

(i) We have discussed, and you recognize and acknowledge the competitive and proprietary aspects of the business of the Company.

(ii) You will devote your full time and efforts to the business of the Company and, during the period of your employment with the Company (the “Term”) and for a period of six (6) months following termination of your employment (unless such termination was without cause or the result of a layoff or the Company fails to pay you 50% of base salary for six (6) months following your termination, in which event this restriction in sub-section (ii) shall end at separation from employment), shall not participate, directly or indirectly, in the same or substantially similar capacity as you provided services to the Company during the last two years of your employment, in any business which is competitive with the Company’s Field of Interest (as described below) unless you have received the prior written consent of the Company. You acknowledge and agree that a business will be deemed competitive with the Company if it (1) conducts research, (2) is developing or intends to develop any product candidate, (3) performs any of the services or manufactures or sells any of the products provided or offered by the Company or (4) performs any other services and/or engages in

Exhibit 10.1

the production, manufacture, distribution or sale of any product that may be purchased in lieu of purchasing services performed or products produced, manufactured, distributed or sold by the Company, in each case within the Field of Interest at any time during the period of your employment with the Company (a “Competitor”). As used herein, the term “Field of Interest” means [***]. You hereby acknowledge and agree that the Field of Interest shall be assessed for purposes of this Agreement as of the date on which your employment with the Company terminates.

(iii) You further acknowledge and agree that, during the course of your employment

with the Company, the Company will furnish, disclose or make available to you confidential and proprietary information related to the Company’s business and that the Company may provide you with unique and specialized training. You also acknowledge that such confidential information and such training have been developed and will be developed by the Company through the expenditure by the Company of substantial time, effort and money and that all such confidential information and training could be used by you to compete with the Company.

(iv) You have been advised to consult with an attorney of your choice in connection with this Agreement and have been provided the time necessary for such consultation as is reasonable under the circumstances and, if applicable to your work location, in compliance with any state-specific review periods (10 business days for Massachusetts).

(b)     Non-Solicitation. During the Term and for a period of twelve (12) months following

termination of your employment, whether such termination is voluntary or involuntary, you shall not, without the prior written consent of the Company:

(i) either individually or on behalf of or through any third party, solicit, divert or appropriate or attempt to solicit, divert or appropriate, any vendor, business relationship or customer of the Company during the Term, with whom you had business-related communications on behalf of the Company or on whose project you provided services during the Term, with the effect or intention of reducing or limiting the amount of business that such vendor, business counterparty or customer does with the Company and for the benefit of a Competitor; or

(ii) either individually or on behalf of or through any third party, directly or indirectly, solicit, entice or persuade or attempt to solicit, entice or persuade any employees of or consultants to the Company (other than your spouse), who have been employees or consultants of the Company at any time during the Term, or who are employees or consultants of the Company at the time of the solicitation, with whom you had business-related communications on behalf of the Company or with whom you worked during the Term, to leave the services of the Company to provide services to any Competitor.

(c)     Reasonableness of Restrictions. You further acknowledge and agree that (i) the activities which are prohibited by this Section 1 are narrow and reasonable in relation to the skills which represent your principal salable asset both to the Company and to your other prospective employers, and (ii) given the global nature of the Company’s business, including its need to market its services and sell its products in a large geographic area in order to have a sufficient customer base to make the Company’s business profitable, the geographic, length of time and substantive scope of the provisions of this Section 1 are reasonable, legitimate and fair to you.

Exhibit 10.1

(d)     Survival of Acknowledgments and Agreements. Except as expressly set forth hereunder, your acknowledgments and agreements set forth in this Section 1 shall survive the termination of your employment with the Company for the periods set forth above.

2.     Protected Information.

(a)Confidentiality Obligations. You shall at all times, both during the Term and thereafter, maintain in confidence and shall not, without the prior written consent of the Company, use, except in the course of performance of your duties for the Company, disclose or give to others any Confidential Information of the Company. As used herein, the term “Confidential Information” shall mean any information which is disclosed to or developed by you during the course of performing services for, or receiving training from, the Company, and is not generally available to the public, including but not limited to confidential information concerning business plans, customers, future customers, suppliers, licensors, licensees, partners, investors, affiliates or others, training methods and materials, financial information, sales prospects, client lists, Company Inventions (as defined in Section 3), or any other scientific, technical, trade or business secret or confidential or proprietary information of the Company or of any third party provided to you during the Term.

The seeking of such injunction or order shall not affect the Company’s right to seek and obtain damages or other equitable relief on account of any such actual or threatened breach. In the event the Company takes any court action with respect to your breach or threatened breach of this Agreement, and prevails in such action, you shall be obligated to reimburse the Company for its reasonable attorneys’ fees and costs incurred in such action.

This Severance and Change of Control Agreement (the “Agreement”) is entered into as of November 6, 2023 by and between Madrigal Pharmaceuticals Inc., a Delaware corporation (the “Company”), and Carole Huntsman (“Executive”).

WHEREAS, Executive is employed by the Company, and because of such employment, possesses detailed knowledge of the Company and its business and operations;

WHEREAS, Executive’s continued service to the Company is very important to the future success of the Company;

WHEREAS, the Company desires to enter into this Agreement to provide Executive with certain financial protection in the event that Executive’s employment terminates under certain circumstances, and thereby to provide Executive with incentives to remain with the Company; and

WHEREAS, the Board of Directors of the Company (the “Board”) acting through the Compensation Committee has determined that it is in the best interests of the Company to enter into this Agreement.

NOW THEREFORE for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and Executive agree as follows:

(a)Cause. As used herein, “Cause” shall include (and is not limited to): (i) dishonesty with respect to the Company or any affiliate, parent or subsidiary of the Company; (ii) insubordination; (iii) substantial malfeasance or nonfeasance of duty; (iv) unauthorized disclosure of confidential information; (v) Executive’s breach of any material provision of any employment, consulting, advisory, non-disclosure, invention, assignment, non-competition, or similar agreement between Executive and the Company; or (vi) conduct substantially prejudicial to the business of the Company or any affiliate, parent or subsidiary of the Company. The Board shall have sole discretion to determine the existence of “Cause’’ and its determination will be conclusive on Executive and the Company; provided that the Board may delegate its power to act under this paragraph (a) to a committee of the Board in which case the determination of such committee shall be conclusive. “Cause” is not limited to events which have occurred prior to the termination of Executive’s service, nor is it necessary that the Board’s finding of “Cause” occur prior to such termination. If the Board determines, subsequent to Executive’s termination of service, that either prior or subsequent to Executive’s termination Executive engaged in conduct which would constitute “Cause,” then Executive shall have no right to any benefit or compensation under this Agreement.

(b)Change of Control. As used herein, a “Change of Control” shall mean the occurrence of any of the following events:

(i)Ownership. Any “Person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the “Beneficial Owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company

representing fifty percent (50%) or more of the total voting power represented by the Company’s then outstanding voting securities (excluding for this purpose any such voting securities held by the Company, or any affiliate, parent or subsidiary of the Company, or by any employee benefit plan of the Company) pursuant to a transaction or a series of related transactions which the Board does not approve; or

(ii)Merger/Sale of Assets. (A) A merger or consolidation of the Company, whether or not approved by the Board, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or the parent of such corporation) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or parent of such corporation, as the case may be outstanding immediately after such merger or consolidation; or (B) the stockholders of the Company approve an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; or

For purposes of this Agreement, “Good Reason” shall be interpreted in a manner, and limited to the extent necessary, so that it will not cause adverse tax consequences for either party with respect to Section 409A of the Internal Revenue Code of 1986, as amended (“Code Section 409A”), and any successor statute, regulation and guidance thereto.

(b)Base Salary. As used herein, “Base Salary” shall mean Executive’s annual base salary, excluding reimbursements, bonuses, benefits, and amounts attributable to stock options and other non-cash compensation.

(e)No Duplication. In the event that Executive is eligible for the severance payments and benefits under Section 3 below, Executive shall not be eligible for and shall not receive any of the severance payments and benefits as provided in this Section 2.

3.Distribution Limitation. If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or benefit Executive receives pursuant to a Change of Control (for purposes of this section, a “Payment”) would: (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”); and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be either: (x) the full amount of such Payment; or (y) such lesser amount (with cash payments being reduced before stock option compensation) as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes, and the Excise Tax, results in Executive’s receipt, on an after- tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

4.Timing Of Payments. Notwithstanding any other provision with respect to the timing of payments under Sections 2 or 3, if at the time of Executive’s termination, Executive is deemed to be a “specified employee” of the Company (within the meaning of Code Section 409A(a)(2)( B)(i) and any successor statute, regulation and guidance thereto (“Code Section 409A”)), then limited only to the extent necessary to comply with the requirements of Code Section 409A any payments to which Executive may become entitled under Sections 2 or 3, which are subject to Code Section 409A (and not otherwise exempt from its application) will be

withheld until the first (1st) business day of the seventh (7th) month following the termination of Executive’s employment at which time Executive shall be paid an aggregate amount equal to the accumulated, but unpaid, payments otherwise due to Executive under the terms of Sections 2 or 3.

5.Release of Claims. The Company shall not be obligated to pay Executive any of the compensation set forth in Sections 2 and 3, unless and until Executive has executed, and not revoked, a timely full and general release of all claims against the Company and any affiliate, parent or subsidiary, and its and their officers, directors, employees, and agents, in a form satisfactory to the Company. Any payments due pursuant to Sections 2 and 3 of this Agreement shall commence sixty (60) days after the Executive’s last day of employment, at which time Executive shall have no right to revoke any previously executed general release of claims.

6.No Impact on Employment Status. This Agreement is not intended to confer, and shall not be interpreted as conferring, any additional employment rights on Executive, and has no impact on either party’s right to terminate Executive’s employment under contract or applicable law.

7.Enforceability; Reduction. If any provision of this Agreement shall be deemed invalid or unenforceable as written, this Agreement shall be construed, to the greatest extent possible, or modified, to the extent allowable by law, in a manner which shall render it valid and enforceable and any limitation on the scope or duration of any provision necessary to make it valid and enforceable shall be deemed to be a part thereof.

[*personally identifiable information*]

Dear Mardi:

This letter is to confirm our understanding with respect to (i) your agreement not to compete

with Madrigal Pharmaceuticals, Inc. or its current or future subsidiaries or Affiliates (collectively, the “Company”) while employed by the Company or engage in prohibited solicitation during your employment and for a period thereafter, (ii) your agreement to protect and preserve information and property which is confidential and proprietary to the Company and your agreement concerning Company Inventions specified herein (with the terms and conditions agreed to in this letter being referred to as the “Agreement”). For these purposes, an “Affiliate” is a person or entity that controls, is controlled by or is under common control with the Company, with “control” meaning the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a person or entity, whether through the ownership of voting securities, by contract, or otherwise. You hereby acknowledge and agree that you are an “at-will” employee and that no provision of this Agreement shall be construed to create an express or implied employment contract, or a promise of employment for a specific period of time, and the Company expressly reserves the right to end your employment at any time, with or without notice or cause.

In consideration of your employment by the Company, the mutual promises and covenants contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby mutually acknowledged, we have agreed as follows:

1.Prohibited Competition and Solicitation.

(a)     Certain Acknowledgments and Agreements.

(i) We have discussed, and you recognize and acknowledge the competitive and proprietary aspects of the business of the Company.

(ii) You will devote your full time and efforts to the business of the Company and, during the period of your employment with the Company (the “Term”) you shall not participate, directly or indirectly, in any capacity, in any business which is competitive with the Company’s Field of Interest (as described below) unless you have received the prior written consent of the Company. You acknowledge and agree that a business will be deemed competitive with the Company if it (1) conducts research, (2) is developing or intends to develop any product candidate, (3) performs any of the services or manufactures or sells any of the products provided or offered by the Company or (4) performs any other services and/or engages in the production, manufacture, distribution or sale of any product that may be purchased in lieu of purchasing services performed or products produced, manufactured, distributed or sold by the Company, in each case within the Field of Interest at any time during the period of your employment with the Company (a “Competitor”). As used herein, the term “Field of Interest” means [***]. You hereby acknowledge and

Exhibit 10.2

agree that the Field of Interest shall be assessed for purposes of this Agreement as of the date on which your competitive activity occurs.

(iii) You further acknowledge and agree that, during the course of your employment

with the Company, the Company will furnish, disclose or make available to you confidential and proprietary information related to the Company’s business and that the Company may provide you with unique and specialized training. You also acknowledge that such confidential information and such training have been developed and will be developed by the Company through the expenditure by the Company of substantial time, effort and money and that all such confidential information and training could be used by you to compete with the Company.

(iv) You have been advised to consult with an attorney of your choice in connection with this Agreement and have been provided the time necessary for such consultation as is reasonable under the circumstances and, if applicable to your work location, in compliance with any state-specific review periods.

(b)     Non-Solicitation. During the Term and for a period of twelve (12) months following

termination of your employment, whether such termination is voluntary or involuntary, you shall not, without the prior written consent of the Company:

(i) either individually or on behalf of or through any third party, solicit, divert or appropriate or attempt to solicit, divert or appropriate, any vendor, business relationship or customer of the Company during the Term, with whom you had business-related communications on behalf of the Company or on whose project you provided services during the Term, with the effect or intention of reducing or limiting the amount of business that such vendor, business counterparty or customer does with the Company and for the benefit of a Competitor; or

(ii) either individually or on behalf of or through any third party, directly or indirectly, solicit, entice or persuade or attempt to solicit, entice or persuade any employees of or consultants to the Company (other than your spouse), who are employees or consultants of the Company at the time of the solicitation, with whom you had business-related communications on behalf of the Company or with whom you worked during the Term, to leave the services of the Company to provide services to any Competitor.

(c)     Reasonableness of Restrictions. You further acknowledge and agree that (i) the activities which are prohibited by this Section 1 are narrow and reasonable in relation to the skills which represent your principal salable asset both to the Company and to your other prospective employers, and (ii) given the global nature of the Company’s business, including its need to market its services and sell its products in a large geographic area in order to have a sufficient customer base to make the Company’s business profitable, the geographic, length of time and substantive scope of the provisions of this Section 1 are reasonable, legitimate and fair to you.

(d)     Survival of Acknowledgments and Agreements. Except as expressly set forth hereunder, your acknowledgments and agreements set forth in this Section 1 shall survive the termination of your employment with the Company for the periods set forth above.

2.     Protected Information.

Exhibit 10.2

(a)Confidentiality Obligations. You shall at all times, both during the Term and thereafter, maintain in confidence and shall not, without the prior written consent of the Company, use, except in the course of performance of your duties for the Company, disclose or give to others any Confidential Information of the Company. As used herein, the term “Confidential Information” shall mean any information which is disclosed to or developed by you during the course of performing services for, or receiving training from, the Company, and is not generally available to the public, including but not limited to confidential information concerning business plans, customers, future customers, suppliers, licensors, licensees, partners, investors, affiliates or others, training methods and materials, financial information, sales prospects, client lists, Company Inventions (as defined in Section 3), or any other scientific, technical, trade or business secret or confidential or proprietary information of the Company or of any third party provided to you during the Term. In the event anyone not employed or otherwise engaged by the Company seeks information from you in regard to any such Confidential Information or any other secret or confidential work of the Company, or concerning any fact or circumstance relating thereto, you will promptly notify the chief executive officer of the Company.

(b)Limited Exceptions. The restrictions in Section 2(a) hereof shall not apply to information that, as can be established by competent written records: (i) was publicly known at the time of the Company’s communication thereof to you; (ii) becomes publicly known through no fault of yours subsequent to the time of the Company’s communication thereof to you; (iii) was in your possession free of any obligation of confidence at the time of the Company’s communication thereof to you; or (iv) is developed by you independently of and without reference to or use of any of the Company’s Confidential Information. In the event that you are required by law, regulation or court order to disclose any of the Company’s Confidential Information, you shall (i) first notify the Company of such disclosure requirement, unless such advance notice requirement is prohibited by law and (ii) furnish only that portion of the Confidential Information that is legally required and will exercise all reasonable efforts to obtain reliable assurances that confidential treatment will be accorded the Confidential Information.

(c)Protected Rights. Nothing in this Agreement prohibits or restricts you or your attorney from initiating communications directly with, responding to an inquiry from, or providing testimony before the Securities and Exchange Commission, any regulatory or self-regulatory organization, or any other governmental authority. Nothing in this Agreement in any way prohibits or is intended to restrict or impede you from discussing the terms and conditions of your employment with coworkers or union representatives or exercising any other protected rights under Section 7 of the National Labor Relations Act.

(d)Section 2870. You understand that the provisions of this Agreement requiring assignment of inventions to the Company do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870, which provides as follows:

(a) Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer's equipment, supplies, facilities, or trade secret information except for those inventions that either: (1) Relate at the time of conception or reduction to practice of the invention to the employer's business, or actual or demonstrably anticipated research or development of the employer; or (2) Result from any work performed by the employee for the employer.

Exhibit 10.2

(b) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.

You will advise the Company promptly in writing of any invention that you believe meets the criteria in California Labor Code Section 2870.

(e)Survival of Acknowledgments and Agreements. Except as expressly set forth hereunder, your acknowledgments and agreements set forth in this Section 2 shall survive the termination of your employment with the Company.

3.    Ownership of Intellectual Property Ideas.

(a)Property of the Company. As used in this Agreement, the term “Inventions” shall mean all ideas, discoveries, creations, manuscripts and properties, innovations, improvements, know-how, inventions, designs, developments, apparatus, techniques, methods, biological processes, cell lines, laboratory notebooks and formulae, whether patentable, copyrightable or not, including all rights to obtain, register, perfect and enforce any of the foregoing. You hereby agree that any Inventions which you may conceive, reduce to practice or develop during the Term, whether in connection with the business activities of the Company or otherwise, alone or in conjunction with any other party, whether during or out of regular business hours, and whether at the request or upon the suggestion of the Company, or otherwise (collectively, the “Company Inventions”), shall be the sole and exclusive property of the Company. You hereby assign to the Company all of your right, title and interest in and to all such Company Inventions and hereby agree that you shall not publish any of the Company Inventions without the prior written consent of the Company.

(b)Cooperation. During the Term, you agree that, without further compensation, you will disclose promptly to the Company in writing, all Company Inventions you conceive, reduce to practice or develop during the Term (or, if based on or related to any Confidential Information of the Company obtained by you during the Term, within one (1) year after the termination of your employment). You further agree that you will fully cooperate with the Company, its attorneys and agents in the preparation and filing of all papers and other documents as may be reasonably required to perfect the Company’s rights in and to any of such Company Inventions, including, but not limited to, joining in any proceeding to obtain patents, copyrights, trademarks or other legal rights of the United States and of any and all other countries on such Company Inventions; provided, that, the Company will bear the expense of such proceedings (including all of your reasonable expenses). You further agree that any patent or other legal right covering any Company Invention so issued to you, personally, shall be assigned by you to the Company without charge by you. You further acknowledge that all original works of authorship made by you, whether alone or jointly with others within the scope of your employment and which are protectable by copyright are “works made for hire” within the meaning of the United States Copyright Act, 17 U.S.C. § 101, as amended, the copyright of which shall be owned solely, completely and exclusively by the Company. If any Company Invention is considered to be work not included in the categories of work covered by the United States Copyright Act, 17 U.S.C. § 101, as amended, such work shall be owned solely by, or hereby assigned or transferred completely and exclusively to, the Company. If the Company is unable because of your mental or physical incapacity or for any other reason, after reasonable effort, to secure your signature on any document or documents needed to obtain or enforce any patent, copyright, trademarks or any other rights covering Inventions or original works of authorship assigned by you to the Company as required above, you hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as your agent and attorney-in-fact, to act for and in your behalf and stead to execute and file any application or assignment and to do all other lawfully

Exhibit 10.2

permitted acts to further the prosecution and issuance to the Company of patents, copyright registrations, trademark registrations or similar protections covering the Inventions with the same legal force and effect as if executed by you.

(c)Under the Economic Espionage Act of 1996, as amended by the Defend Trade Secrets Act of 2016, notwithstanding any other provision of this Agreement: (i) you will not be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that is made: (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document that is filed under seal in a lawsuit or other proceeding; or (ii) if you file a lawsuit for retaliation for reporting a suspected violation of law, you may disclose trade secrets to your attorney and use the trade secret information in the court proceeding if you (1) file any document containing the trade secret under seal; and (2) do not disclose the trade secret, except pursuant to court order.

4.     Provisions Necessary and Reasonable/Breach/Attorneys’ Fees. You agree that (i) the provisions of Sections 1, 2 and 3 of this Agreement are necessary and reasonable to protect the Company’s Confidential Information, Company Inventions, and goodwill and (ii) in the event of any breach of any of the covenants set forth herein, the Company would suffer substantial irreparable harm and would not have an adequate remedy at law for such breach. In recognition of the foregoing, you agree that in the event of a breach or threatened breach of any of these covenants, in addition to such other remedies as the Company may have at law, without posting any bond or security, the Company shall be entitled to seek and obtain equitable relief, in the form of specific performance, and/or temporary, preliminary or permanent injunctive relief, or any other equitable remedy which then may be available. The seeking of such injunction or order shall not affect the Company’s right to seek and obtain damages or other equitable relief on account of any such actual or threatened breach. In the event the Company takes any court action with respect to your breach or threatened breach of this Agreement, and prevails in such action, you shall be obligated to reimburse the Company for its reasonable attorneys’ fees and costs incurred in such action. If you prevail in such action, the Company shall be obliged to reimburse you for your reasonable attorneys’ fees and costs incurred in such action.

SEVERANCE AND CHANGE OF CONTROL AGREEMENT

This Severance and Change of Control Agreement (the “Agreement”) is entered into as of February 25, 2024 by and between Madrigal Pharmaceuticals Inc., a Delaware corporation (the “Company”), and Mardi Dier (“Executive”).

WHEREAS, Executive is employed by the Company, and because of such employment, possesses detailed knowledge of the Company and its business and operations;

WHEREAS, Executive’s continued service to the Company is very important to the future success of the Company;

WHEREAS, the Company desires to enter into this Agreement to provide Executive with certain financial protection in the event that Executive’s employment terminates under certain circumstances, and thereby to provide Executive with incentives to remain with the Company; and

WHEREAS, the Board of Directors of the Company (the “Board”) acting through the Compensation Committee has determined that it is in the best interests of the Company to enter into this Agreement.

NOW THEREFORE for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and Executive agree as follows:

1.Definitions.

(a)Cause. As used herein, “Cause” shall mean: (i) dishonesty with respect to the Company or any affiliate, parent or subsidiary of the Company; (ii) insubordination; (iii) substantial malfeasance or willful nonfeasance of duty; (iv) unauthorized disclosure of confidential information; (v) Executive’s material breach of any material provision of any employment, consulting, advisory, non-disclosure, invention, assignment, non-competition, or similar agreement between Executive and the Company; or (vi) misconduct substantially prejudicial to the business of the Company or any affiliate, parent or subsidiary of the Company.

If within 180 days after Executive’s termination of service (for any reason other than a termination for Cause), the Board discovers that either prior or subsequent to Executive’s termination Executive engaged in

Exhibit 10.2

conduct which constituted “Cause,” then such termination shall be deemed to have been for Cause.

(b)Change of Control. As used herein, a “Change of Control” shall mean the occurrence of any of the following events:

(i)Ownership. Any “Person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the “Beneficial Owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the Company’s then outstanding voting securities (excluding for this purpose any such voting securities held by the Company, or any affiliate, parent or subsidiary of the Company, or by any employee benefit plan of the Company) pursuant to a transaction or a series of related transactions which the Board does not approve; or

(ii)Merger/Sale of Assets. (A) A merger or consolidation of the Company, whether or not approved by the Board, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or the parent of such corporation) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or parent of such corporation, as the case may be outstanding immediately after such merger or consolidation; or (B) the stockholders of the Company approve an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; or

(iii)Change in Board Composition. A change in the composition of the Board as a result of which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” shall mean directors who either (A) are directors of the Company as of the date of this Agreement, or (B) are elected, or nominated for election to the Board with the affirmative votes of at least a majority of the Incumbent Directors, or by a committee of the Board made up of at least a majority of the Incumbent Directors, at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of directors to the Company).

(c)Good Reason. As used herein, a “Good Reason” shall mean: (i) Executive, as a condition of remaining an employee of the Company, is required to change the principal location where Executive renders services to the Company to a location more than fifty (50) miles from Executive’s then-current location of employment unless Executive has approved or consented to such change; (ii) there occurs a material adverse change in any of Executive’s titles or Executive’s duties, authority or responsibilities (including reporting responsibilities); or (iii) there occurs a material reduction in Executive’s base salary; provided that any such event shall not constitute grounds for Good Reason unless (x) written notice of termination by Executive for Good Reason is given by Executive within thirty (30) days of

Exhibit 10.2

Executive’s becoming aware of the occurrence of the facts giving rise to such Good Reason, (y) the Company does not cure such event(s) within thirty (30) days after its receipt of Executive’s written notice, and (z) Executive terminates his employment within ninety (90) days after the expiration of the cure period. For purposes of this Agreement, “Good Reason” shall be interpreted in a manner, and limited to the extent necessary, so that it will not cause adverse tax consequences for either party with respect to Section 409A (“Code Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”), and any successor statute, regulation and guidance thereto.

(d)Base Salary. As used herein, “Base Salary” shall mean Executive’s annual base salary, excluding reimbursements, bonuses, benefits, and amounts attributable to stock options and other non-cash compensation.

(c)Equity Acceleration. Acceleration of vesting of any and all outstanding equity awards that would have vested during the period commencing on Executive’s date of termination through and including the date that is twelve (12) months following Executive’s date of termination.

Exhibit 10.2

group coverage, and Executive hereby agrees to notify the Company promptly and in writing should that occur.

(e)No Duplication. In the event that Executive is eligible for the severance payments and benefits under Section 3 below, Executive shall not be eligible for and shall not receive any of the severance payments and benefits as provided in this Section 2.

(e)No Duplication. In the event that Executive is eligible for the severance payments and benefits under Section 2 above, Executive shall not be eligible for and shall not receive any of the severance payments and benefits as provided in this Section 3.

12.No Severance. In the event that Executive’s employment is terminated for any reason other than those outlined in Sections 2 or 3, then Executive shall have no right to any of the severance payments and benefits provided under this Agreement.

Exhibit 10.2

13.Distribution Limitation. If any payment or benefit Executive would receive under this Agreement, when combined with any other payment or benefit Executive receives pursuant to a Change of Control (for purposes of this section, a “Payment”) would: (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”); and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be either: (x) the full amount of such Payment; or (y) such lesser amount (with cash payments being reduced before stock option compensation) as would result in no portion of the Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes, and the Excise Tax, results in Executive’s receipt, on an after- tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax.

14.Timing Of Payments. Notwithstanding any other provision with respect to the timing of payments under Sections 2 or 3, if at the time of Executive’s termination, Executive is deemed to be a “specified employee” of the Company (within the meaning of Code Section 409A(a)(2)( B)(i) and any successor statute, regulation and guidance thereto (“Code Section 409A”)), then limited only to the extent necessary to comply with the requirements of Code Section 409A any payments to which Executive may become entitled under Sections 2 or 3, which are subject to Code Section 409A (and not otherwise exempt from its application) will be withheld until the first (1st) business day of the seventh (7th) month following the termination of Executive’s employment at which time Executive shall be paid an aggregate amount equal to the accumulated, but unpaid, payments otherwise due to Executive under the terms of Sections 2 or 3.

15.Release of Claims. The Company shall not be obligated to pay Executive any of the compensation set forth in Sections 2 and 3, unless and until Executive has executed, and not revoked, a timely full and general release of all claims against the Company and any affiliate, parent or subsidiary, and its and their officers, directors, employees, and agents, in a form satisfactory to the Company. Any payments due pursuant to Sections 2 and 3 of this Agreement shall commence sixty (60) days after the Executive’s last day of employment, at which time Executive shall have no right to revoke any previously executed general release of claims.

16.No Impact on Employment Status. This Agreement is not intended to confer, and shall not be interpreted as conferring, any additional employment rights on Executive, and has no impact on either party’s right to terminate Executive’s employment under contract or applicable law.

17.Enforceability; Reduction. If any provision of this Agreement shall be deemed invalid or unenforceable as written, this Agreement shall be construed, to the greatest extent possible, or modified, to the extent allowable by law, in a manner which shall render it valid and enforceable and any limitation on the scope or duration of any provision necessary to make it valid and enforceable shall be deemed to be a part thereof.

Exhibit 10.3

SUPPLEMENTAL COMPENSATION RECOVERY POLICY

Madrigal Pharmaceuticals, Inc.

Supplemental Compensation Recovery Policy

Adopted by the Board of Directors (“Board”) of Madrigal Pharmaceuticals, Inc. (the

“Company”) on April 26, 2024

The Board and Compensation Committee (the “Committee”) of the Board of Directors of the Company is adopting this Supplemental Compensation Recovery Policy (this “Supplemental Policy”) to provide for the recovery of certain Incentive Compensation not covered by the Company’s Incentive Compensation Recovery Policy (the “Dodd-Frank Policy”) adopted pursuant to Rule 10D-1(b)(1) of the Securities Exchange Act of 1934, as amended. For the avoidance of doubt, if (i) there is a conflict between this Supplemental Policy and the Dodd-Frank Policy, or (ii) both this Supplemental Policy and the Dodd-Frank Policy would require recoupment of the same Incentive Compensation, then the Dodd-Frank Policy will govern.

Statement of Policy

Without limiting the Dodd-Frank Policy, the Company has adopted this Supplemental Policy effective as of April 26, 2024.

To the extent permitted by law, and as it deems appropriate under the circumstances, the Company may seek recovery of Incentive Compensation from a Covered Executive who knowingly, intentionally or recklessly engaged in serious misconduct that resulted in a material violation of the law, the Company’s Corporate Code of Conduct and Ethics (or any successor or replacement code of conduct for employees) or a significant ethics or compliance policy of the Company. The amount of Incentive Compensation that the Committee may seek to recover will be the amount which the Committee, in its discretion, determines would not have been awarded or earned if the circumstances surrounding the Covered Executive’s misconduct had been known to the Company.

In determining whether to recover a payment under this Supplemental Policy, the Committee shall take into account all such facts and circumstances and considerations as it deems appropriate, including whether the assertion of a claim may violate applicable law or prejudice the interests of the Company in any related proceeding or investigation, whether amounts have already been subject to recoupment from a Covered Executive under the Dodd-Frank Policy, and the extent to which the Covered Executive acted in the normal course of the Covered Executive’s duties and in good faith based on facts known to the Covered Executive at the time.

The Committee shall have sole discretion under this Supplemental Policy in determining whether a Covered Executive’s conduct has or has not met any particular standard of conduct under law or Company policy.

Definitions

“Covered Executive” shall mean the Company’s Chief Executive Officer, President, Chief Financial Officer, principal accounting officer (or if there is no such accounting officer, the

Exhibit 10.3

controller), any vice-president of the Company in charge of a principal business unit, division, or function, any other officer who performs a policy-making function for the Company, any other person who performs similar policy-making functions for the Company, and any other employee who may from time to time be deemed subject to this Supplemental Policy by the Committee.

“Incentive Compensation” means all compensation granted, paid or earned by the Covered Executive pursuant to the Company’s annual incentive compensation program and long-term incentive program, including, for the avoidance of doubt, all annual cash incentive payments, cash bonuses, and equity awards (such as stock options, time-based equity awards and performance- based equity awards).

Administration

The Committee has full authority to interpret and administer this Supplemental Policy. The Committee’s determinations under this Supplemental Policy shall be final and binding on all persons, need not be uniform with respect to each individual covered by the Supplemental Policy, and shall be given the maximum deference permitted by law.

The Committee has the authority to determine the appropriate means of recovering Incentive Compensation based on the particular facts and circumstances, which could include, but is not limited to, seeking direct reimbursement, forfeiture of awards, offsets against other payments, and forfeiture of deferred compensation (subject to compliance with Section 409A of the Internal Revenue Code).

Subject to any limitations under applicable law, the Committee may authorize any officer or employee of the Company to take actions necessary or appropriate to carry out the purpose and intent of this Supplemental Policy, provided that no such authorization shall relate to any recovery under this Supplemental Policy that involves such officer or employee.

Non-Exclusive Remedy; Successors

Recovery of Incentive Compensation pursuant to this Supplemental Policy shall not in any way limit or affect the rights of the Company to pursue disciplinary, legal, or other action or pursue any other remedies available to it. This Supplemental Policy shall be in addition to, and is not intended to limit, any rights of the Company to recover Incentive Compensation from Covered Executives under any legal remedy available to the Company and applicable laws and regulations, including but not limited to the Dodd-Frank Policy, the Sarbanes-Oxley Act of 2002, as amended, or pursuant to the terms of any other Company policy, employment agreement, equity award agreement, or similar agreement with a Covered Executive.

This Supplemental Policy shall be binding and enforceable against all Covered Executives and their successors, beneficiaries, heirs, executors, administrators, or other legal representatives.

Amendment

This Supplemental Policy may be amended from time to time by the Committee or the Board of Directors of the Company.

Exhibit 10.3

Effective Date

This Supplemental Policy shall apply to any Incentive Compensation granted, paid or earned on or after April 26, 2024.

Organization, Business and Basis of Presentation

Organization, Business, and Basis of Presentation

Organization and Business

Madrigal Pharmaceuticals, Inc. (the “Company” or “Madrigal”) is a biopharmaceutical company dedicated to transforming care for patients with nonalcoholic steatohepatitis (“NASH”), a serious liver disease that can lead to cirrhosis, liver failure and premature mortality. The Company's medication, Rezdiffra (resmetirom), is a once-daily, oral, liver-directed THR-β agonist designed to target key underlying causes of NASH. In March 2024, Rezdiffra became the first and only FDA-approved therapy for patients with NASH. Rezdiffra is indicated in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis).

Basis of Presentation

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted. Accordingly, the unaudited condensed consolidated financial statements do not include all information and footnotes required by GAAP for complete annual financial statements. However, the Company believes that the disclosures included in these financial statements are adequate to make the information presented not misleading. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments, which include normal recurring adjustments, necessary for a fair statement of such interim results. The interim results are not necessarily indicative of the results that the Company will have for the full year ending December 31, 2024 or any subsequent period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes to those statements for the year ended December 31, 2023.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Principle of Consolidation

The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, and the reported amounts of revenues and expenses during the reporting periods. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits.

The primary objective of the Company’s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company’s cash is deposited in highly rated financial institutions in the United States. The Company invests in money market funds and high-grade, commercial paper and corporate bonds, which management believes are subject to minimal credit and market risk.

Marketable Securities

Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets.

The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion as a component of interest income, net. Realized gains and losses and declines in value, if any, that the Company judges to be the result of impairment or as a result of recognizing an allowance for credit losses on available-for-sale securities are reported as a component of interest income. To determine whether an impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three months ended March 31, 2024 and 2023, the Company determined it did not have any securities that were other-than-temporarily impaired.

Marketable securities are stated at fair value, including accrued interest, with their unrealized gains and losses included as a component of accumulated other comprehensive income or loss, which is a separate component of stockholders’ equity. The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method. During the three months ended March 31, 2024 and 2023, the Company did not have any realized gains or losses on marketable securities.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash equivalents and marketable securities, approximate their fair values. The fair value of the Company’s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2—observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3—unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability.

Financial assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third- party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs.

As of March 31, 2024, the Company’s financial assets valued based on Level 1 inputs consisted of cash and cash equivalents in a money market fund, its financial assets valued based on Level 2 inputs consisted of high-grade corporate and government agency bonds and commercial paper, and it had no financial assets valued based on Level 3 inputs. During the three months ended March 31, 2024 and 2023, the Company did not have any transfers of financial assets between Levels 1 and 2. As of March 31, 2024 and December 31, 2023, the Company did not have any financial liabilities that were recorded at fair value on a recurring basis on the balance sheet.

Inventory

Inventory is stated at the lower of cost or estimated net realizable value, using actual cost, based on a first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels quarterly and writes down inventory subject to expiry or in excess of expected requirements, or that has a cost basis in excess of its expected net realizable value. These write downs are charged to cost of goods sold in the accompanying Consolidated Statements of Income.

The Company considered regulatory approval of its product candidate to be uncertain and product manufactured prior to regulatory approval could not have been sold unless regulatory approval was obtained. As such, the manufacturing costs incurred prior to regulatory approval were not capitalized as inventory, but were expensed as incurred as research and development expenses.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation),

costs for consultants, milestone payments under licensing agreements, and other costs associated with the Company’s preclinical and clinical programs. In particular, the Company has conducted safety studies in animals, optimized and implemented the manufacturing of its drug, and conducted clinical trials, all of which are considered research and development expenditures. Management uses significant judgment in estimating the amount of research and development costs recognized in each reporting period. Management analyzes and estimates the progress of its clinical trials, completion of milestone events per underlying agreements, invoices received and contracted costs when estimating the research and development costs to accrue in each reporting period. Actual results could differ from the Company’s estimates.

Patents

Costs to secure and defend patents are expensed as incurred and are classified as selling, general and administrative expense in the Company’s consolidated statements of operations.

Intangible Assets

Intangible assets with finite lives are amortized to cost of goods sold over their estimated useful lives using the straight-line method. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Stock-Based Compensation

The Company recognizes stock-based compensation expense based on the grant date fair value of stock options, restricted stock units, and other stock-based compensation awards granted to employees, officers, directors, and consultants. Awards that vest as the recipient provides service are expensed on a straight-line basis over the requisite service period.

The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company’s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary.

For other stock-based compensation awards granted to employees and directors that vest based on market conditions, such as the trading price of the Company’s common stock achieving or exceeding certain price targets, the Company uses a Monte Carlo simulation model to estimate the grant date fair value and recognize stock compensation expense over the derived service period. The Monte Carlo simulation model requires key inputs for risk-free interest rate, dividend yield, volatility, and expected life.

The assumptions used in computing the fair value of equity awards reflect the Company’s best estimates but involve uncertainties related to market and other conditions. Changes in any of these assumptions may materially affect the fair value of awards granted and the amount of stock-based compensation recognized.

Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets.

Income Taxes

The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company’s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the

years in which the differences are expected to reverse. The Company currently maintains a 100% valuation allowance on its deferred tax assets.

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company’s net loss and comprehensive loss.

Basic and Diluted Loss Per Common Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the three months ended March 31, 2024 and 2023, diluted net loss per share is the same as basic net loss per share because the inclusion of weighted average shares of common stock issuable upon the exercise of stock options and warrants or vesting of restricted stock units, and common stock issuable upon the conversion of preferred stock would be anti-dilutive. The following table summarizes outstanding securities not included in the computation of diluted net loss per common share, as their inclusion would be anti-dilutive:

	Outstanding at March 31,
	2024	2023
Common stock options	2,458,227	2,676,598
Restricted stock units	530,671	199,125
Performance-based restricted stock units	252,404	—
Preferred stock	2,369,797	2,369,797

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances the disclosures required for operating segments in the Company's annual and interim consolidated financial statements. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the disclosures required for income taxes in the Company's annual consolidated financial statements. The amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-09 on its financial statements.

Liquidity and Uncertainties

Liquidity and Uncertainties

Liquidity and Uncertainties

The Company is subject to risks common to development stage companies and early commercial companies in the biopharmaceutical industry including, but not limited to, uncertainty of product development and commercialization, dependence on key personnel, uncertainty of market acceptance of products and product reimbursement, product liability, uncertain protection of proprietary technology, potential inability to raise additional financing necessary for development and commercialization, and compliance with the U.S. Food and Drug Administration (“FDA”) and other government regulations.

The Company has incurred losses since inception, including approximately $147.5 million for the three months ended March 31, 2024, resulting in an accumulated deficit of approximately $1,483.8 million as of March 31, 2024. To date, the Company has funded its operations primarily through proceeds from sales of the Company’s capital stock and debt financings. In March 2024, the FDA approved Rezdiffra in the U.S. for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Rezdiffra became available in the U.S. in April 2024. In March 2024, the Company completed a public offering and received approximately $574.0 million net cash proceeds. In April 2024, underwriters exercised in full their option to purchase additional shares as part of the public offering, resulting in additional net cash proceeds of approximately $85.9 million. Please see “Note 11 – Subsequent Events” to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for

more information. The Company believes that its cash, cash equivalents and marketable securities will be sufficient to fund operations past one year from the issuance of these financial statements. The Company’s future long-term liquidity requirements will be substantial and will depend on many factors, including the Company’s ability to effectively commercialize Rezdiffra. To meet its future capital needs, the Company may need to raise additional capital through debt or equity financings, collaborations, partnerships or other strategic transactions. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise. The inability of the Company to obtain sufficient funds on acceptable terms when needed, if at all, could have a material adverse effect on the Company’s business, results of operations and financial condition. The Company has the ability to delay certain research activities and related clinical expenses if necessary due to liquidity concerns until a date when those concerns are relieved.

Long Term Debt

Long Term Debt

In May 2022 the Company and its wholly-owned subsidiary, Canticle Pharmaceuticals, Inc., entered into the $250.0 million Loan Facility with the several banks and other financial institutions or entities party thereto (each, a “Lender” and collectively referred to as the “Lenders”), and Hercules Capital, Inc. (“Hercules”), in its capacity as administrative agent and collateral agent for itself and the Lenders. Under the terms of the Loan Facility, the first $50.0 million tranche was drawn at closing. The Company also could draw up to an additional $125.0 million in two separate tranches upon achievement of certain resmetirom clinical and regulatory milestones. A fourth tranche of $75.0 million could have been drawn by the Company, subject to the approval of Hercules. The Loan Facility had a minimum interest rate of 7.45% and adjusted with changes in the prime rate. The Company was originally scheduled to pay interest-only monthly payments of accrued interest under the Loan Facility through May 1, 2025, for a period of 36 months. In March 2024, the interest-only period was extended to May 1, 2026 when the Company achieved a milestone when Rezdiffra received FDA approval. The interest only period can further be extended to May 3, 2027, upon the achievement of future revenue milestones, subject to compliance with applicable covenants. The Loan Facility originally matured in May 2026, but the maturity date was extended to May 2027 when the Company achieved a milestone upon receipt of FDA approval in March 2024. The Loan Facility is secured by a security interest in substantially all of the Company’s assets, other than intellectual property. It includes an end of term charge of 5.35% of the aggregate principal amount, which is accounted for in the loan discount. In connection with the first tranche drawn at closing, the Company issued Hercules a warrant to purchase 14,899 shares of Company common stock, which had a Black-Scholes value of $0.6 million.

On February 3, 2023, the Company entered into the First Amendment (the “Amendment”) to the Loan Facility (as amended, the “Amended Loan Facility”). Under the Amended Loan Facility, an additional $35.0 million was drawn under a second, expanded, $65.0 million tranche (“Tranche 2”) in February of 2023 following the Company’s achievement of the Phase 3 clinical development milestone. An additional $15.0 million was drawn under Tranche 2 in June of 2023. The remaining $15.0 million available under Tranche 2 was drawn in September of 2023 in accordance with the Amended Loan Facility. The third tranche (“Tranche 3”) of $75.0 million remains unchanged by the Amendment, and such borrowings became available when the Company achieved a milestone with FDA approval for Rezdiffra in March 2024. As of March 31, 2024, the Company has not drawn down on Tranche 3, and the $75.0 million remains available until June 12, 2024. Coincident with the expansion of Tranche 2 borrowing capacity by $15.0 million, the Amendment reduced the fourth tranche under the Loan Facility (“Tranche 4”) by $15.0 million to $60.0 million, which is available subject to Hercules’ sole discretion. In connection with the $35.0 million drawn under Tranche 2 at the closing of the Amendment, $15.0 million drawn in June of 2023, and $15.0 million drawn in September of 2023, the Company issued to Hercules and

affiliates Tranche 2 Warrants to purchase an aggregate of 4,555 shares of common stock, which had a Black-Scholes value of $0.9 million. The Amendment reduced the interest rate under the Amended Loan Facility to the greater of (i) the prime rate as reported in The Wall Street Journal plus 2.45% and (ii) 8.25%. The Amendment and the Amended Loan Facility summary terms were disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on February 9, 2023.

The Loan Facility includes affirmative and restrictive financial covenants commencing on January 1, 2023, including maintenance of a minimum cash, cash equivalents and liquid funds covenant of $35.0 million, which may decrease in certain circumstances if the Company achieves certain clinical milestones and a revenue milestone, and a revenue-based covenant that could apply commencing at or after the time that financial reporting is due for the quarter ending September 30, 2024. The Loan Facility contains event of default provisions for: the Company’s failure to make required payments or maintain compliance with covenants under the Loan Facility; the Company’s breach of certain representations or default under certain obligations outside the Loan Facility; insolvency, attachment or judgment events affecting the Company; and any circumstance which has occurred or could reasonably be expected to have a material adverse effect on the Company, provided that, any failure to achieve a clinical milestone or approval milestone under the Loan Facility shall not in and of itself constitute a material adverse effect. The Loan Facility also includes customary covenants associated with a secured loan facility, including covenants concerning financial reporting obligations, and certain limitations on indebtedness, liens (including a negative pledge on intellectual property and other assets), investments, distributions (including dividends), collateral, investments, distributions, transfers, mergers or acquisitions, taxes, corporate changes, and deposit accounts.

As of March 31, 2024, the outstanding principal under the Loan Facility was $115.0 million. The interest rate as of March 31, 2024 was 10.95%. As of March 31, 2024, the Company was in compliance with all loan covenants and provisions.

Future minimum payments, including interest and principal, under the loans payable outstanding as of March 31, 2024 are as follows (in thousands):

Period Ending March 31, 2024:	Amount
2024	$	9,619

Each common stockholder is entitled to one vote for each share of common stock held. The common stock will vote together with all other classes and series of stock of the Company as a single class on all actions to be taken by the Company’s stockholders. Each share of common stock is entitled to receive dividends, as and when declared by the Company’s Board of Directors (the “Board”). The Company has never declared cash dividends on its common stock and does not expect to do so in the foreseeable future.

Preferred Stock

The Series A and B Preferred Stock have a par value of $0.0001 per share and are convertible into shares of the common stock at a one-to-one ratio, subject to adjustment as provided in the Certificates of Designation of Preferences, Rights and Limitations of Series A Preferred Stock and Series B Preferred Stock that the Company filed with the Secretary of State of the State of Delaware on June 21, 2017 and December 22, 2022, respectively. The terms of the Series A and B Preferred Stock are set forth in such Certificates of Designation. Each share of the Series A and B Preferred Stock is convertible into shares of common stock following notice that may be given at the holder’s option. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, after the satisfaction in full of the debts of the Company and the payment of any liquidation preference owed to the holders of shares of capital stock of the Company

ranking prior to the Series A and B Preferred Stock upon liquidation, the holders of the Series A and B Preferred Stock shall participate pari passu with the holders of the common stock (on an as-if-converted-to-Common-Stock basis) in the net assets of the Company. Shares of the Series A and B Preferred Stock will generally have no voting rights, except as required by law. Shares of the Series A and B Preferred Stock will be entitled to receive dividends before shares of any other class or series of capital stock of the Company (other than dividends in the form of the common stock) equal to the dividend payable on each share of the common stock, on an as-converted basis.

On March 18, 2024, the Company entered into an Underwriting Agreement with Goldman Sachs & Co. LLC, Jefferies LLC, Cowen and Company, LLC, Evercore Group L.L.C. and Piper Sandler & Co, as representatives of the several underwriters named therein (the “2024 Underwriters”), pursuant to which the Company sold to the 2024 Underwriters in an underwritten public offering (the “2024 Offering”): (i) 750,000 shares of common stock at a public offering price of $260.00 per share, (ii) pre-funded warrants (the “2024 Pre-Funded Warrants”) to purchase 1,557,692 shares of common stock at a public offering price of $259.9999 per 2024 Pre-Funded Warrant, which represents the per share public offering price for the common stock less a $0.0001 per share exercise price for each such Pre-Funded Warrant, and (iii) a 30-day option for the 2024 Underwriters to purchase up to 346,153 additional shares of common stock at the public offering price of $260.00 per share (the “Underwriters’ Option”). The 2024 Offering closed on March 21, 2024. The gross proceeds of the 2024 Offering was $600.0 million, and the Company received net proceeds, after deducting the underwriting discount and commissions and other estimated offering expenses payable by the Company, of approximately $574.0 million.

The Underwriters’ Option was later exercised in full, and closed on April 2, 2024. The net proceeds to the Company for the exercise of the Underwriters’ Option, after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company, was approximately $85.9 million. See Note 11- Subsequent Events for more information.

The Company intends to use the net proceeds from the 2024 Offering for its commercial activities in connection with the launch of Rezdiffra in the U.S. and for general corporate purposes, including, without limitation, research and development expenditures, ongoing clinical trial expenditures, manufacture and supply of drug substance and drug products, potential ex-U.S. commercialization or partnering opportunities, potential acquisitions or licensing of new technologies, capital expenditures and working capital.

The 2024 Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of 2024 Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of 2024 Pre-Funded Warrants may increase or decrease this percentage, but not in excess of 19.99%, by providing at least 61 days prior notice to the Company.

2023 Public Offering

On September 28, 2023, the Company entered into an Underwriting Agreement with Goldman Sachs & Co. LLC, as representative of the several underwriters named therein (the “2023 Underwriters”), pursuant to which the Company sold to the 2023 Underwriters in an underwritten public offering (the “2023 Offering”): (i) 1,248,098 shares of common stock at a public offering price of $151.69 per share, and (ii) pre-funded warrants (the “2023 Pre-Funded Warrants”) to purchase 2,048,098 shares of common stock at a public offering price of $151.6899 per 2023 Pre-Funded Warrant, which represents the per share public offering price for the common stock less a $0.0001 per share exercise price for each such 2023 Pre-Funded Warrant. The 2023 Offering closed on October 3, 2023.

The gross proceeds of the 2023 Offering was $500.0 million, and the Company received net proceeds, after deducting the underwriting discount and commissions and other estimated offering expenses payable by the Company, of approximately $472.0 million. The Company intends to use the net proceeds from the Offering for its clinical and commercial activities in preparation for the launch of resmetirom in the U.S. and for general corporate purposes, including, without limitation, research and development expenditures, clinical trial expenditures, manufacture and supply of drug substance and drug products, potential acquisitions or licensing of new technologies, capital expenditures and working capital.

The 2023 Pre-Funded Warrants are exercisable at any time after the date of issuance. A holder of 2023 Pre-Funded Warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than 9.99% of the number of shares of common stock outstanding immediately after giving effect to such exercise. A holder of

2023 Pre-Funded Warrants may increase or decrease this percentage, but not in excess of 19.99%, by providing at least 61 days prior notice to the Company.

At-The-Market Issuance Sales Agreement

In June 2021, the Company entered into an at-the-market sales agreement (the “2021 Sales Agreement”) with Cowen and Company, LLC (“Cowen”), pursuant to which the Company could, from time to time, issue and sell shares of its common stock. The 2021 Sales Agreement initially authorized an aggregate offering of up to $200.0 million in shares of the Company’s common stock, at the Company’s option, through Cowen as its sales agent. Sales of common stock through Cowen could be made by any method that is deemed an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, including by means of ordinary brokers’ transactions at market prices, in block transactions or as otherwise agreed by the Company and Cowen. Subject to the terms and conditions of the 2021 Sales Agreement, Cowen would use commercially reasonable efforts consistent with its normal trading and sales practices to sell the common stock based upon the Company’s instructions (including any price, time or size limits or other customary parameters or conditions the Company imposed). In total, under the 2021 Sales Agreement the Company sold 1,235,943 shares for an aggregate of $199.9 million in gross proceeds, with net proceeds to the Company of approximately $195.8 million after deducting commissions and other transaction costs through December 31, 2022. All shares were sold pursuant to the Company’s effective shelf registration statement on Form S-3 (the “Registration Statement”) and the prospectus supplement relating thereto. As of March 31, 2024, no amounts remained reserved and available for sale under the 2021 Sales Agreement and the related prospectus supplement.

In May 2023, the Company amended the 2021 Agreement (the “Sales Agreement Amendment”), with Cowen, pursuant to which the Company may, from time to time, issue and sell an additional $200.0 million in shares of its common stock. The Company is not obligated to make any sales of its common stock under this arrangement. Any shares sold will be sold pursuant to the Registration Statement and prospectus supplement filed pursuant to the Registration Statement. The Sales Agreement Amendment authorizes sales of shares of the Company’s common stock, from time to time, at the Company’s option, through Cowen as its sales agent. Sales of common stock through Cowen may be made by any method that is deemed an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, and as described in the prospectus supplement.

During the three months ended March 31, 2024, under the Sales Agreement Amendment, the Company sold no shares. In total under the Sales Agreement Amendment, the Company sold 98,101 shares for an aggregate of $25.2 million in gross proceeds, with net proceeds to the Company of approximately $24.5 million after deducting commissions and other transaction costs. All shares were sold pursuant to the Company’s effective Registration Statement and the prospectus supplement relating thereto. As of March 31, 2024, $174.8 million remained reserved and available for sale under the 2023 Sales Agreement Amendment and the Company’s related prospectus supplement.

The 2015 Stock Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock, restricted stock units and other stock-based compensation awards to employees, officers, directors, and consultants of the Company. The administration of the 2015 Stock Plan is under the general supervision of the Compensation Committee of the Board. The terms of stock options awarded under the 2015 Stock Plan, in general, are determined by the Compensation Committee, provided the exercise price per share generally shall not be set at less than the fair market value of a share of the common stock on the date of grant and the term shall not be greater than ten years from the date the option is granted.

2023 Inducement Plan

In September 2023, the Company adopted the 2023 Inducement Plan (the “Inducement Plan”), pursuant to which the Company may from time to time make equity grants to new employees as a material inducement to their employment. The Inducement Plan was adopted without stockholder approval, pursuant to Nasdaq Listing Rule 5635(c)(4), and is administered by the Compensation Committee of the Board. The Inducement Plan provides for the granting of non-statutory stock options, restricted stock, restricted stock units, performance stock units and other stock-based compensation awards to new employees, but does not allow for the granting of incentive stock options. The terms of the stock options under the Inducement Plan, in general, are determined by the Compensation Committee, provided the exercise price per share generally shall not be set at less than the fair market value of a share of the common stock on the date of grant and the

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2024

Accounting Policies [Abstract]

Principle of Consolidation

Principle of Consolidation

The consolidated financial statements include the financial statements of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, and the reported amounts of revenues and expenses during the reporting periods. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. The Company maintains its cash in bank accounts, the balance of which, at times, exceeds Federal Deposit Insurance Corporation insured limits.

The primary objective of the Company’s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company’s cash is deposited in highly rated financial institutions in the United States. The Company invests in money market funds and high-grade, commercial paper and corporate bonds, which management believes are subject to minimal credit and market risk.

Marketable Securities

Marketable Securities

Marketable securities consist of investments in high-grade corporate obligations and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations, they are classified as current assets on the consolidated balance sheets.

The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion as a component of interest income, net. Realized gains and losses and declines in value, if any, that the Company judges to be the result of impairment or as a result of recognizing an allowance for credit losses on available-for-sale securities are reported as a component of interest income. To determine whether an impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash equivalents and marketable securities, approximate their fair values. The fair value of the Company’s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2—observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3—unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability.

Financial assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third- party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs.

Inventory is stated at the lower of cost or estimated net realizable value, using actual cost, based on a first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels quarterly and writes down inventory subject to expiry or in excess of expected requirements, or that has a cost basis in excess of its expected net realizable value. These write downs are charged to cost of goods sold in the accompanying Consolidated Statements of Income.

The Company considered regulatory approval of its product candidate to be uncertain and product manufactured prior to regulatory approval could not have been sold unless regulatory approval was obtained. As such, the manufacturing costs incurred prior to regulatory approval were not capitalized as inventory, but were expensed as incurred as research and development expenses.

Research and Development Costs

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs are comprised of costs incurred in performing research and development activities, including internal costs (including stock-based compensation),

costs for consultants, milestone payments under licensing agreements, and other costs associated with the Company’s preclinical and clinical programs. In particular, the Company has conducted safety studies in animals, optimized and implemented the manufacturing of its drug, and conducted clinical trials, all of which are considered research and development expenditures. Management uses significant judgment in estimating the amount of research and development costs recognized in each reporting period. Management analyzes and estimates the progress of its clinical trials, completion of milestone events per underlying agreements, invoices received and contracted costs when estimating the research and development costs to accrue in each reporting period. Actual results could differ from the Company’s estimates.

Patents

Patents

Costs to secure and defend patents are expensed as incurred and are classified as selling, general and administrative expense in the Company’s consolidated statements of operations.

Intangible Assets

Intangible Assets

Intangible assets with finite lives are amortized to cost of goods sold over their estimated useful lives using the straight-line method. Intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.

Stock-Based Compensation

Stock-Based Compensation

The Company recognizes stock-based compensation expense based on the grant date fair value of stock options, restricted stock units, and other stock-based compensation awards granted to employees, officers, directors, and consultants. Awards that vest as the recipient provides service are expensed on a straight-line basis over the requisite service period.

The Company uses the Black-Scholes option pricing model to determine the grant date fair value of stock options as management believes it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options. Expected volatility is based upon an industry estimate or blended rate including the Company’s historical trading activity. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary.

For other stock-based compensation awards granted to employees and directors that vest based on market conditions, such as the trading price of the Company’s common stock achieving or exceeding certain price targets, the Company uses a Monte Carlo simulation model to estimate the grant date fair value and recognize stock compensation expense over the derived service period. The Monte Carlo simulation model requires key inputs for risk-free interest rate, dividend yield, volatility, and expected life.

The assumptions used in computing the fair value of equity awards reflect the Company’s best estimates but involve uncertainties related to market and other conditions. Changes in any of these assumptions may materially affect the fair value of awards granted and the amount of stock-based compensation recognized.

Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize the related deferred tax assets.

Income Taxes

Income Taxes

The Company uses the asset and liability method to account for income taxes. Deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the Company’s financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates expected to be in effect in the

years in which the differences are expected to reverse. The Company currently maintains a 100% valuation allowance on its deferred tax assets.

Comprehensive Loss

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company’s net loss and comprehensive loss.

Basic and Diluted Loss Per Common Share

Basic and Diluted Loss Per Common Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the three months ended March 31, 2024 and 2023, diluted net loss per share is the same as basic net loss per share because the inclusion of weighted average shares of common stock issuable upon the exercise of stock options and warrants or vesting of restricted stock units, and common stock issuable upon the conversion of preferred stock would be anti-dilutive.
