ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Operations and Business Applied Therapeutics, Inc. (the “Company”) is a clinical-stage biopharmaceutical company developing a pipeline of novel product candidates against validated molecular targets in indications of high unmet medical need. In particular, the Company is currently targeting treatments for cardiovascular disease, galactosemia and diabetic complications. The Company was incorporated in Delaware on January 20, 2016 and is headquartered in New York, New York. On May 16, 2019, the Company completed an initial public offering (“IPO”) in which the Company issued and sold 4,000,000 shares of its common stock at a public offering price of $10.00 per share, for aggregate gross proceeds of $40.0 million. The Company received net of proceeds $34.6 million, after deducting underwriting discounts and commissions and offering costs. Prior to the completion of the IPO, the Company primarily funded its operations with proceeds from the sale of convertible preferred stock (see Note 8). In connection with the IPO, the Company effected a 55.2486-for-1 stock split of its issued and outstanding shares of common stock and convertible preferred stock. The stock split became effective on April 26, 2019. Stockholders entitled to fractional shares as a result of the forward stock split received cash payment in lieu of receiving fractional shares. All share and per share amounts for all periods presented in the accompanying condensed financial statements and notes thereto have been retroactively adjusted, where applicable, to reflect this stock split. Shares of common stock underlying outstanding stock options and other equity instruments were proportionately increased and the respective per share value and exercise prices, if applicable, were proportionately decreased in accordance with the terms of the agreements governing such securities. Upon the closing of the IPO on May 16, 2019, all of the then-outstanding shares of convertible preferred stock automatically converted into 7,538,671 shares of common stock on a one-for-one basis. Subsequent to the closing of the IPO, there were no shares of convertible preferred stock outstanding. On November 12, 2019, the Company completed a private placement (the “Private Placement”), pursuant to which it issued and sold 1,380,344 shares of the Company’s common stock at a price of $14.50 per share, for net proceeds of $18.4 million after deducting placement agent discounts and commissions and offering costs. On January 28, 2020, the Company completed its secondary public offering (the “Secondary Public Offering”), pursuant to which it issued and sold 2,741,489 shares of common stock at a public offering price of $45.50 per share, with an additional 411,223 shares sold pursuant to the underwriters’ full exercise of their option to purchase additional shares. The aggregate net proceeds received by the Company from the offering, after deducting underwriting discounts and commissions and offering costs, were $134.1 million. The accompanying unaudited condensed financial statements as of March 31, 2020 and December 31, 2019 and for the three months ended March 31, 2020 and 2019 have been prepared by the Company in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2019 included in the Annual Report, filed with the SEC on March 13, 2020 (the “Annual Report”). The unaudited condensed financial statements have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited condensed financial statements contain all adjustments which are necessary for a fair presentation of the Company’s financial position as of March 31, 2020, results of operations for the three months ended March 31, 2020 and 2019 and cash flows for the three months ended March 31, 2020 and 2019. Such adjustments are of a normal and recurring nature. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2020. Liquidity The Company has incurred, and expects to continue to incur, significant operating losses and negative cash flows for at least the next several years as it continues to develop its drug candidates. To date, the Company has not generated any revenue, and it does not expect to generate revenue unless and until it successfully completes development and obtains regulatory approval for one of its product candidates. Management believes that the Company’s existing cash, cash equivalents, and investments will allow the Company to continue its operations for at least 12 months from the issuance date of these financial statements. After 12 months from the issuance of these financial statements, the Company may need to obtain additional funding. The Company may pursue additional cash resources through public or private financings. Risks and Uncertainties The Company is subject to risks common to companies in the biotechnology industry, including, but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations and reliance on third‑party manufacturers. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant Accounting Policies The significant accounting policies and estimates used in preparation of the condensed financial statements are described in the Company’s audited financial statements as of and for the year ended December 31, 2019, and the notes thereto, which are included in the Annual Report. Except as detailed below, there have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2020. Stock‑Based Compensation–Restricted Stock Units The Company accounts for restricted stock units in accordance with the authoritative guidance for stock-based compensation. The fair value of restricted stock units is measured at the grant date based on the closing market price of the Company’s common stock on the date of grant, and is recognized as expense on a straight-line basis over the period of vesting. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur. Recent Accounting Pronouncements On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology applies to financial instruments measured at amortized cost, including loan receivables and held-to-maturity debt securities, off-balance sheet credit exposures and net investments in leases recognized by a lessor. ASC 326 also made changes to the accounting for available-for-sale debt securities, where credit losses are required to be presented as an allowance as opposed to a write-down. The FASB issued authoritative guidance that amends guidance on reporting credit losses for assets, including available-for-sale marketable securities and any other financial assets not excluded from the scope that have the contractual right to receive cash. For available-for-sale marketable securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, will require that credit losses be presented as an allowance rather than as a write-down. For available-for-sale debt securities in an unrealized position, the Company assesses whether a decline in fair value resulted from credit losses or other factors. Management considers the extent to which fair value is less than amortized cost, any changes to the credit rating of the security, and adverse conditions specifically related to the security. If the assessment indicates a credit loss exists, an allowance is recorded that is limited to the amount the amortized cost exceeds the fair value. Any impairment that is not recognized through the allowance for credit loss is recognized in other comprehensive income. The Company adopted ASC 326 using the modified retrospective method approach, where a cumulative-effect adjustment to credit loss allowance would be reflected in retained earnings. The adoption of this standard did not have an impact on the Company’s balance sheet as there were no credit losses identified. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years beginning after December 15, 2019. Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. The amendments eliminated certain disclosure requirements such as the elimination of disclosing the valuation process for Level 3 fair value measurements. Other amendments in the update did not impact the Company. The Company adopted the amendments on January 1, 2020 with no impact on our financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes. The new standard intended to simplify the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard is effective for annual periods beginning after December 15, 2020 and interim periods within, with early adoption permitted. Adoption of the standard requires certain changes to primarily be made prospectively, with some changes to be made retrospectively. The Company is currently evaluating the impact adoption of ASU 2019-12 will have on its financial statements.
