| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business Description 9 Meters Biopharma, Inc. (the “Company”) is a clinical-stage biopharmaceutical company focused on rare and unmet needs in gastroenterology. The Company’s pipeline includes drug candidates for NM-002, a proprietary long-acting GLP-1 agonist for short bowel syndrome (SBS), an orphan designated disease and larazotide, a Phase 3 tight junction regulator being evaluated for celiac disease. On April 30, 2020, the Company completed its merger with privately-held RDD Pharma, Ltd., an Israel corporation (“RDD”) (the “RDD Merger”) and changed its name from Innovate Biopharmaceuticals, Inc. to 9 Meters Biopharma, Inc. Basis of Presentation The unaudited condensed consolidated interim financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. These financial statements are unaudited and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments and accruals) necessary for a fair statement of the balance sheets, operating results, and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2020 or any other future period. Certain information and footnote disclosure normally included in the annual financial statements prepared in accordance with U.S. GAAP have been omitted in accordance with the SEC’s rules and regulations for interim reporting. The Company’s financial position, results of operations and cash flows are presented in U.S. Dollars. These financial statements and related notes should be read in conjunction with the audited financial statements and related notes thereto for the year ended December 31, 2019 , included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 , filed with the SEC on March 20, 2020. Except as noted below under the section entitled “Recently Issued Accounting Standards—Accounting Pronouncements Adopted,” there have been no material changes to the Company’s significant accounting policies during the three and nine months ended September 30, 2020 , as compared to the significant accounting policies disclosed in Note 1 of the Company’s financial statements for the years ended December 31, 2019 and 2018 included in the Company’s Annual Report on Form 10-K. However, the following accounting policies are the most critical in fully understanding the Company’s financial condition and results of operations. Basis of Consolidation The accompanying consolidated financial statements reflect the operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Shelf Registration Filing On March 15, 2018, the Company filed a shelf registration statement that was declared effective on July 13, 2018 (the “Prior Registration Statement”). The Prior Registration Statement did not include various types of securities as is customary and was set to expire in July 2021. On October 2, 2020, the Company filed a shelf registration statement that was declared effective on October 19, 2020 (the “Current Registration Statement”), so the Prior Registration Statement was terminated effective October 19, 2020. Pursuant to the Current Registration Statement, the Company may from time to time offer, issue and sell in one or more offerings of various types of securities up to an aggregate dollar amount of $200 million . On July 22, 2020, the Company filed a prospectus supplement and associated sales agreement related to an ATM pursuant to which the Company may sell, from time to time, common stock with an aggregate offering price of up to $40 million through Truist Securities, Inc. (previously SunTrust Robinson Humphrey), or Truist, as sales agent, for general corporate purposes (the “Sales Agreement”). In October 2020, the Company entered into an amendment to the Sales Agreement to reflect the termination of the Prior Registration Statement and effectiveness of the Current Registration Statement. As of September 30, 2020, the Company had sold 3,246,745 shares of common stock pursuant to the Sales Agreement for net proceeds of approximately $2.4 million. March 2019 Offering On March 17, 2019, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with SDS Capital Partners II, LLC and certain other accredited investors, pursuant to which the Company sold, on March 18, 2019 , 4,181,068 shares of common stock and issued short-term warrants (the “Short-Term Warrants”) to purchase up to 4,181,068 shares of common stock, and long-term warrants (the “March Long-Term Warrants”) to purchase up to 2,508,634 shares of common stock. Pursuant to the Purchase Agreement, the Company issued the common stock and warrants at a purchase price of $2.33 per unit for aggregate proceeds of approximately $9.7 million . The March Long-Term Warrants issued were exercisable for five years commencing on the six-month anniversary of March 18, 2019, had an initial exercise price of $2.56 per share, subject to certain adjustments, and had an expiration date of March 18, 2024 . The Short-Term Warrants were originally exercisable for a period of one year from March 18, 2019, had an expiration date of March 18, 2020 and had an initial exercise price of $4.00 per share, subject to certain adjustments. The Short-Term Warrants and March Long-Term Warrants were accounted for as warrant liabilities in accordance with Accounting Standards Codification (“ASC”) 480 —Distinguishing Liabilities from Equity . On February 6, 2020, the Company and the holders of the Company’s outstanding Short-Term Warrants amended the Short-Term Warrants to extend the exercise period of each Short-Term Warrant by six months . The Short-Term Warrants, as amended, were exercisable for up to an aggregate of 4,181,068 shares of the Company’s common stock, par value $0.0001 per share, until September 18, 2020. In addition, on February 12, 2020, the Company offered to amend outstanding warrants, including the Short-Term Warrants, to (i) shorten the exercise period to expire concurrently with the closing of the RDD Merger on April 30, 2020 and (ii) reduce the exercise price to $0.10 per share (the “Offer to Amend and Exercise”). All other terms of each Short-Term Warrant remained in full force and effect and were not impacted by this amendment. On April 29, 2020, upon closing of the Offer to Amend and Exercise, the Short-Term Warrants were fully exercised at an exercise price of $0.10 per share. Additional Issuance of Warrants On April 25, 2019, the Company entered into an amendment (the “Amendment”) to the Purchase Agreement dated as of March 17, 2019, between the Company and each purchaser party thereto. The Amendment (i) deleted Section 4.12 of the Purchase Agreement, which generally prohibited the Company from issuing, entering into agreements to issue, announcing proposed issuances, selling or granting certain securities between the date of the Purchase Agreement and the date that was 45 days following the closing date thereunder and (ii) gave each purchaser the right to purchase, for $0.125 per underlying share, an additional warrant to purchase shares of the Company’s common stock having an exercise price per share of $2.13 and otherwise having the terms of the March Long-Term Warrants (collectively, the “New Warrants”) pursuant to a securities purchase agreement entered into among the Company and each purchaser that desired to purchase the New Warrants. On May 17, 2019, the Company and each purchaser entered into such Securities Purchase Agreement (the “New Agreement”), and the Company issued New Warrants exercisable for an aggregate of 3,897,010 shares of the Company’s common stock. The New Warrants were exercisable for five years beginning on the six -month anniversary of the date of issuance until the five-year anniversary of their date of issuance. The New Warrants had an initial exercise price equal to $2.13 per share, subject to certain adjustments. The New Warrants were accounted for as warrant liabilities in accordance with ASC 480— Distinguishing Liabilities from Equity . Offer to Amend and Exercise On February 12, 2020, the Company offered to amend certain outstanding warrants in the Offer to Amend and Exercise. The warrants amended included the warrants classified as equity issued in 2018 (the “2018 Equity Warrants”), the outstanding Short-Term Warrants and the outstanding March Long-Term Warrants and the New Warrants. On April 29, 2020, an aggregate of 12,230,418 shares of common stock were tendered, amended and exercised for $0.10 per share for aggregate gross proceeds of approximately $1.2 million . All of the Short-Term Warrants, March Long-Term Warrants and New Warrants were fully exercised at an exercise price of $0.10 per share. April 2019 Offering On April 29, 2019, the Company entered into a Securities Purchase Agreement (the “April Purchase Agreement”) with certain institutional and accredited investors providing for the sale by the Company of up to 4,318,272 shares of its common stock at a purchase price of $2.025 per share. Pursuant to the April Purchase Agreement, the Company agreed to issue unregistered warrants (the “April Warrants”) to purchase up to 4,318,272 shares of common stock. Subject to certain ownership limitations, the April Warrants were exercisable beginning on the date of their issuance until the five-and-a-half-year anniversary of their date of issuance at an initial exercise price of $2.13 per share. The exercise price of the April Warrants was subject to adjustment for stock splits, reverse splits, and similar capital transactions as described in the April Warrants. The net proceeds from the offering and the private placement were approximately $7.9 million , after deducting commissions and estimated offering costs. The Company granted the placement agent warrants to purchase up to 215,914 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants had substantially the same terms as the April Warrants, except that the Placement Agent Warrants had an exercise price of $2.53 per share and had a term of 5 years from the effective date of the offering. The Company also paid the placement agent a reimbursement for non-accountable expenses in the amount of $35,000 and a reimbursement for legal fees and expenses of the placement agent in the amount of $25,000 . On December 19, 2019, the Company and each of the purchasers of the April Warrants and Placement Agent Warrants (collectively, the “Exchange Warrants”) entered into separate exchange agreements (the “Exchange Agreement”), pursuant to which the Company agreed to issue to the purchasers an aggregate of 5,441,023 shares of the Company’s common stock (the “Exchange Shares”), at a ratio of 1.2 Exchange Shares for each purchaser warrant in exchange for the cancellation and termination of all of the outstanding Exchange Warrants. See “Fair Value of Financial Instruments” below for additional details. RDD Merger Financing On April 29, 2020, the Company entered into a securities purchase agreement with various accredited investors pursuant to which the Company agreed to issue and sell to the investors units (“Units”) consisting of (i) one share of Series A Convertible Preferred Stock (the "Series A Preferred Stock") and (ii) one five -year warrant (the "Preferred Warrants") to purchase one share of Series A Preferred Stock (the "RDD Merger Financing"). On May 4, 2020, the Company closed the RDD Merger Financing and the Company sold an aggregate of (i) 382,779 shares of Series A Preferred Stock, par value $0.0001 per share, which converted into 38,277,900 shares of common stock on June 30, 2020, upon receipt of approval by the Company’s stockholders (the “Automatic Conversion”), and (ii) Preferred Warrants to purchase up to 382,779 shares of Series A Preferred Stock, which following the Automatic Conversion became exercisable for 38,277,900 shares of common stock. The exercise price of the Preferred Warrants was $58.94 per share of Series A Preferred Stock, and following the Automatic Conversion, became $0.5894 per share of common stock, subject to adjustments as provided under the terms of the Preferred Warrants. In addition, broker warrants covering 8,112 Units and broker warrants covering 10,899 shares of Series A Preferred Stock, which following the Automatic Conversion became exercisable for 2,712,300 shares of common stock, were issued in connection with the RDD Merger Financing. Gross proceeds from the RDD Merger Financing were approximately $22.6 million with net proceeds of approximately $19.2 million after deducting commissions and estimated offering costs. See Note 3 — Merger & Acquisition for additional details. Business Risks The Company faces risks, including those associated with biopharmaceutical companies whose products are in various stages of development. These risks include, among others, risks related to the potential effects of the ongoing coronavirus outbreak and related mitigation efforts on the Company's clinical, financial and operational activities, the Company’s need for additional financing to achieve key development milestones, the need to defend intellectual property rights, and the dependence on key members of management. See Note 2—Liquidity and Going Concern for further discussion of the risks related to the coronavirus outbreak. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the financial statements. Areas of the financial statements where estimates may have the most significant effect include accrued expenses, share-based compensation, valuation of the derivative liability and warrant liabilities, valuation allowance for income tax assets, management’s estimate of the acquisition costs associated with acquired in-process research and development and management’s assessment of the Company’s ability to continue as a going concern. Changes in the facts or circumstances underlying these estimates could result in material changes and actual results could differ from these estimates. Accrued Expenses The Company incurs periodic expenses such as research and development, licensing fees, salaries and benefits, and professional fees. The Company is required to estimate its expenses resulting from obligations under contracts with clinical research organizations, vendors and consulting agreements that have been incurred by the Company prior to being invoiced. This process involves reviewing quotations and contracts, identifying services that have been performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been invoiced or otherwise notified of the actual cost. The majority of the Company’s service providers invoice monthly in arrears for services performed or when contractual milestones are met. The Company estimates accrued expenses as of each balance sheet date based on facts and circumstances known at that time. Accrued expenses consisted of the following: September 30, December 31, 2019 Accrued compensation and benefits $ 1,210,927 $ 574,332 Accrued clinical expenses 4,591,044 4,143,269 Other accrued expenses 265,246 30,150 Total $ 6,067,217 $ 4,747,751 Derivative Liability The Company accounts for derivative instruments in accordance with ASC 815, Derivative and Hedging, which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other financial instruments or contracts and requires recognition of all derivatives on the condensed consolidated balance sheet at fair value. The Company’s derivative financial instruments consist of embedded options in the Company’s convertible notes. The embedded derivatives include provisions that provide the noteholder with certain conversion and put rights at various conversion or redemption values as well as certain call options for the Company. See Note 4—Debt for further details. Classification of Warrants The Company accounts for warrants in accordance with ASC 480, Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging, to determine whether the warrants should be classified as equity or liability. The warrants the Company issued during 2019 are freestanding financial instruments that contain net settlement options and may require the Company to settle these warrants in cash under certain circumstances. As such, the Company has classified these warrants as liabilities on the accompanying condensed consolidated balance sheets. The warrant liabilities were initially recorded at fair value on the date of issuance and were subsequently re-measured to fair value at each balance sheet date until the warrant liabilities were exercised. Changes in the fair value of the warrants are recognized as a non-cash component of other income and expense in the accompanying condensed consolidated statements of operations and comprehensive loss. All of the warrants accounted for as warrant liabilities have been exercised or settled as of September 30, 2020 . On May 4, 2020, the Company issued the Preferred Warrants, which are freestanding financial instruments that give the warrant holder the right but not the obligation to purchase the equity security at the warrant exercise price. The Company is not required to settle these warrants in cash and as such, the Company has classified these warrants as equity on the accompanying condensed consolidated balance sheets. Research and Development Research and development expenses consist of costs incurred to further the Company’s research and development activities and include salaries and related employee benefits, manufacturing of pharmaceutical active ingredients and drug products, costs associated with clinical trials, nonclinical activities, regulatory activities, research-related overhead expenses and fees paid to expert consultants, external service providers and contract research organizations which conduct certain research and development activities on behalf of the Company. Costs incurred in the research and development of products are charged to research and development expense as incurred. Costs for preclinical studies and clinical trial activities are recognized based on an evaluation of the vendors’ progress towards completion of specific tasks, using data such as patient enrollment, clinical site activations or information provided by vendors regarding their actual costs incurred. Payments for these activities are based on the terms of individual contracts and payment timing may differ significantly from the period in which the services were performed. The Company determines accrual estimates through reports from and discussions with applicable personnel and outside service providers as to the progress or state of completion of trials, or the services completed. The estimates of accrued expenses as of each balance sheet date are based on the facts and circumstances known at the time. Although the Company does not expect its estimates to be materially different from amounts incurred, the Company’s estimates and assumptions for clinical trial costs could differ significantly from actual costs incurred, which could result in increases or decreases in research and development expenses in future periods when actual results are known. Nonrefundable advance payments for goods and services that will be used in future research and development activities are expensed when the goods have been received or when the activity is performed, rather than when payment is made. Acquired In-process Research and Development The Company has acquired, and may in the future acquire, rights to develop and commercialize new drug candidates and/or other in-process research and development assets. The up-front acquisition payments, as well as future milestone payments that are deemed probable to achieve and do not meet the definition of a derivative, are expensed as acquired in-process research and development provided that the drug has not achieved regulatory approval for marketing, and, absent obtaining such approval, have no alternative future use. Share-Based Compensation The Company recognizes share-based compensation expense for grants of stock options based on the grant-date fair value of those awards using the Black-Scholes option-pricing model. Share-based compensation expense is generally recognized on a straight-line basis over the requisite service period for awards expected to vest. Share-based compensation expense includes an estimate, which is made at the time of grant, of the number of awards that are expected to be forfeited. This estimate is revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Under the Black-Scholes option-pricing model, fair value is calculated based on assumptions with respect to: • Expected dividend yield. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on the Company’s common stock. • Expected stock-price volatility. Due to limited trading history as a public company, the expected volatility is derived from the average historical volatilities of publicly traded companies within the Company’s industry that the Company considers to be comparable to the Company’s business over a period approximately equal to the expected term. In evaluating comparable companies, the Company considers factors such as industry, stage of life cycle, financial leverage, size and risk profile. • Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term. • Expected term. The expected term represents the period that the stock-based awards are expected to be outstanding. Due to limited history of stock option exercises, the Company estimates the expected term of employee stock options based on the simplified method, which calculates the expected term as the average of the time-to-vesting and the contractual life of the options. Pursuant to Accounting Standards Update (“ASU”) 2018-07, the Company has elected to use the contractual life of the option as the expected term for non-employee options. Periodically, the Board may approve the grant of restricted stock units (“RSUs”) pursuant to the Company’s 2012 Omnibus Incentive Plan, as amended, which represent the right to receive shares of the Company’s common stock based on terms of the agreement. The fair value of RSUs is recognized as share-based compensation expense generally on a straight-line basis over the service period, net of estimated forfeitures. The grant date fair value of an RSU represents the closing price of the Company’s common stock on the date of grant. Fair Value of Financial Instruments Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Financial instruments recorded in the accompanying condensed consolidated balance sheets are categorized based on the inputs to valuation techniques as follows: • Level 1 - defined as observable inputs based on unadjusted quoted prices for identical instruments in active markets; • Level 2 - defined as inputs other than Level 1 that are either directly or indirectly observable in the marketplace for identical or similar instruments in markets that are not active; and • Level 3 - defined as unobservable inputs in which little or no market data exists where valuations are derived from techniques in which one or more significant inputs are unobservable. The fair value of the embedded derivative issued in connection with the Unsecured Convertible Note and the Additional Note, further described in Note 4—Debt, was determined by using a Monte Carlo simulation technique (“MCS”) to value the embedded derivative associated with each note. As part of the MCS valuation, a discounted cash flow (“DCF”) model is used to value the debt on a stand-alone basis and determine the discount rate to utilize in both the DCF and MCS models. The significant estimates used in the DCF model include the time to maturity of the convertible debt and calculated discount rate, which includes an estimate of the Company’s specific risk premium. The MCS methodology calculates the theoretical value of an option based on certain parameters, including: (i) the threshold of exercising the option, (ii) the price of the underlying security, (iii) the time to expiration, or expected term, (iv) the expected volatility of the underlying security, (v) the risk-free rate and (vi) the number of paths. These valuation techniques involve management’s estimates and judgment based on unobservable inputs and are classified in Level 3. The table below summarizes the valuation inputs into the MCS model for the derivative liability associated with the Unsecured Convertible Note and the Additional Convertible Note on their respective dates of issuance as of March 8, 2019 and January 10, 2020, respectively, and at the end of the period as of September 30, 2020 . Derivative Liability September 30, January 10, March 8, 2020 2020 2019 Discount rate 21.8% 21.6% 29.3% Expected stock price volatility 83.3% 103.9% 101.1% Risk-free interest rate 0.1% 1.6% 2.5% Expected term 1.3 years 2 years 2 years Price of the underlying common stock $0.82 $0.65 $1.99 The fair values of the warrants at their respective dates of issuance further described above in the sections entitled “March 2019 Offering,” “Additional Issuance of Warrants,” and “April 2019 Offering” were determined through the use of an MCS model. The MCS methodology calculates the theoretical value of an option based on certain parameters, including (i) the threshold of exercising the option, (ii) the price of the underlying security, (iii) the time to expiration, or expected term, (iv) the expected volatility of the underlying security, (v) the risk-free interest rate and (vi) the number of paths. Given the high level of the selected volatilities, the methodology selected simulates the Company’s market value of invested capital (“MVIC”) through the maturity date of the respective warrants (ranging from one year to five-and-a-half years). Further, the estimated future stock price of the Company is calculated by subtracting the debt plus accrued interest from the MVIC. The significant estimates used in the MCS model include management’s estimated probability of future financing and liquidation events. Upon a fundamental transaction (as defined in the applicable warrant agreement), each holder of Short-Term Warrants and each holder of the March Long-Term Warrants and New Warrants (collectively, the “Long-Term Warrants”) can elect to require the Company or a successor entity to purchase such holder’s outstanding, unexercised warrants for a cash payment (or under certain circumstances other consideration) equal to the Black-Scholes value of the warrants on the date of consummation of the fundamental transaction, calculated in accordance with the terms and using the assumptions specified in the applicable warrant agreement. Due to the RDD Merger, the Company entered into the Exchange Agreements with the holders of the Exchange Warrants, pursuant to which the Company agreed to issue the purchasers an aggregate of 5,441,023 shares in exchange for the cancellation and termination of the Exchange Warrants. On December 26, 2019, an aggregate of 2,994,762 warrants were exchanged for 3,593,714 shares of the Company’s common stock. During the nine months ended September 30, 2020 , 1,539,424 warrants were exchanged for 1,847,309 shares of the Company’s common stock. In addition, the Company amended the Short-Term Warrants and Long-Term Warrants in the Offer to Amend in Exercise on February 12, 2020. Management assumed that the holders of the Short-Term Warrants and Long-Term Warrants would elect to receive cash payments under the respective warrant agreements following completion of the RDD Merger. As such, the Company determined the fair value of the Short-Term Warrants and Long-Term Warrants immediately prior to the Offer to Amend and Exercise, for financial reporting purposes, through the use of the Black-Scholes model. Subsequent to the Offer to Amend and Exercise, the Company determined the fair value of the Short-Term Warrants and Long-Term Warrants using the reduced exercise price of $0.10 as of April 28, 2020. The estimates underlying the assumptions used in both the MCS model and Black-Scholes model are subject to risks and uncertainties and may change over time, and the assumptions used in both the MCS model and the Black-Scholes model for financial reporting purposes generally differ from the assumptions that would be applied in determining a payout under the applicable warrant agreements. These valuation techniques involve management’s estimates and judgment based on unobservable inputs and are classified in Level 3. The Company recognized a gain in fair value of the Short-Term Warrants and Long-Term Warrants of approximately $2.6 million during the nine months ended September 30, 2020 , and $2.5 million and $0.1 million during the three and nine months ended September 30, 2019 , respectively. All of the Short-Term Warrants and Long-Term Warrants were exercised in the Offer to Amend and Exercise, which closed on April 29, 2020. During the nine months ended September 30, 2020 , the Company recognized warrant inducement expense of approximately $7.2 million . There was no warrant inducement expense recognized during the three months ended September 30, 2020 or the three and nine months ended September 30, 2019. The warrant inducement expense represents the accounting fair value of consideration issued to induce conversion of the Exchange Warrants and exercise of the warrants in the Offer to Amend and Exercise. The table below summarizes the valuation inputs into the MCS model for the Short-Term Warrants and Long-Term Warrants at their respective dates of issuance. Short-Term Warrants Long-Term Warrants March 18, 2019 March 18, 2019 May 17, 2019 Conversion price $4.00 $2.56 $2.13 Expected stock price volatility 122.0% 85.2% 83.4% Risk-free interest rate 2.5% 2.2% 2.2% Expected term 1 year 5 years 5 years Price of the underlying common stock $2.48 $2.48 $1.58 The table below summarizes the range of valuation inputs into the Black-Scholes model for the Exchange Warrants on their date of issuance and immediately prior to the exchange.
