BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS
BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS	1. BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS Overview ANI Pharmaceuticals, Inc. and its consolidated subsidiaries, ANIP Acquisition Company and ANI Pharmaceuticals Canada Inc. (together, “ANI,” the “Company,” “we,” “us,” or “our”), is an integrated specialty pharmaceutical company focused on delivering value to our customers by developing, manufacturing, and marketing high quality branded and generic prescription pharmaceuticals, including for diseases with high unmet medical need. We focus on niche and high barrier to entry opportunities, including controlled substances, oncology products (anti-cancer), hormones and steroids, and complex formulations. Our three pharmaceutical manufacturing facilities, of which two are located in Baudette, Minnesota and one is located in Oakville, Ontario, are together capable of producing oral solid dose products, as well as semi-solids, liquids and topicals, controlled substances, and potent products that must be manufactured in a fully-contained environment. Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In our opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations, comprehensive income, and cash flows. The consolidated balance sheet at December 31, 2020 has been derived from audited financial statements as of that date. The unaudited interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the U.S. Securities and Exchange Commission (the “SEC”). We believe that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously distributed in our Annual Report on Form 10-K for the year ended December 31, 2020. Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of ANI Pharmaceuticals, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. Foreign Currency We have a subsidiary located in Canada. The subsidiary conducts its transactions in U.S. dollars and Canadian dollars, but its functional currency is the U.S. dollar. The results of any non-U.S. dollar transactions are remeasured in U.S. dollars at the applicable exchange rates during the period and resulting foreign currency transaction gains and losses are included in the determination of net income. Our gain or loss on transactions denominated in foreign currencies was immaterial for the three and nine months ended September 30, 2021 and 2020. Unless otherwise noted, all references to “$” or “dollar” refer to the U.S. dollar. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us 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 amount of revenues and expenses during the reporting period. In the accompanying unaudited interim condensed consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, revenue recognition, allowance for credit losses, variable consideration determined based on accruals for chargebacks, administrative fees and rebates, government rebates, returns and other allowances, allowance for inventory obsolescence, valuation of financial instruments and intangible assets, accruals for contingent liabilities, fair value of long-lived assets, income tax provision or benefit, deferred taxes and valuation allowance, determination of right-of-use assets and lease liabilities, purchase price allocations, and the depreciable lives of long-lived assets. Because of the uncertainties inherent in such estimates, actual results may differ from those estimates. Management periodically evaluates estimates used in the preparation of the financial statements for reasonableness. We are subject to risks and uncertainties as a result of the novel coronavirus (“COVID-19”) pandemic. We are unable to predict the impact that the COVID-19 pandemic will continue to have on our future business, financial condition, and results of operations due to numerous uncertainties. These uncertainties include the occurrence of recurring outbreaks and their severity and the duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact and the direct and indirect economic effects of the pandemic and containment measures, among others. We remain unable to predict the future impact on our estimates and assumptions. There was no material impact to these estimates or assumptions in our consolidated financial statements as of and for the three and nine months ended September 30, 2021 and 2020. Actual results could differ from those estimates, which may change our estimates in future periods. We continue to closely monitor the impact of the COVID-19 pandemic on our business. Geographic Information Based on the distinct nature of our operations, our internal management structure, and the financial information that is evaluated regularly by our Chief Operating Decision Maker, we determined that we operate in one reportable segment. Our operations are located in the United States and Canada. The majority of the assets of the Company are located in the United States. The following table depicts the Company’s revenue by geographic operations during the following periods: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ Location of Operations 2021 2020 2021 2020 United States ​ $ 51,100 ​ $ 52,094 ​ $ 152,007 ​ $ 146,602 ​ Canada ​ 961 ​ 885 ​ 3,200 ​ 4,621 ​ Total Revenue ​ $ 52,061 ​ $ 52,979 ​ $ 155,207 ​ $ 151,223 ​ ​ The following table depicts the Company’s property and equipment, net according to geographic location as of: ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ September 30, 2021 ​ December 31, 2020 United States ​ $ 25,512 ​ $ 26,960 Canada ​ 14,014 ​ 14,309 Total property and equipment, net ​ $ 39,526 ​ $ 41,269 ​ Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted We have evaluated all issued and unadopted Accounting Standards Updates and believe the adoption of these standards will not have a material impact on our condensed consolidated statements of operations, comprehensive income, balance sheets, or cash flows. Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued guidance simplifying the accounting for certain financial instruments with characteristics of liabilities and equity, including certain convertible instruments and contracts on an entity’s own equity. The new standard removes the separation models required for convertible debt with cash conversion features and convertible instruments with beneficial conversion features. It also removes certain settlement conditions that are currently required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation for convertible instruments. We early adopted this guidance as of January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements but will impact how we account for newly issued convertible instruments in future periods. ​ In November 2019, the FASB issued guidance simplifying the accounting for income taxes by removing the following exceptions: 1) exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, 2) exception requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, 3) exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary, and 4) exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments also simplify accounting for income taxes by doing the following: 1) requiring that an entity recognize a franchise tax or similar tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, 2) requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction, 3) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements, 4) requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, and 5) making minor Codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. Most of the provisions of this guidance were to be adopted on a prospective basis. Items 2) and 3) of the “removal” provisions were to be adopted on either a full or modified retrospective basis and item 4) of the “simplifying” provisions was to be adopted on a full retrospective basis. The guidance was effective for reporting periods beginning after December 15, 2020, including interim periods within that fiscal year. We adopted this guidance as of January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements.

REVENUE RECOGNITION AND RELATED

REVENUE RECOGNITION AND RELATED ALLOWANCES	9 Months Ended
	Sep. 30, 2021
REVENUE RECOGNITION AND RELATED ALLOWANCES
REVENUE RECOGNITION AND RELATED ALLOWANCES	2. REVENUE RECOGNITION AND RELATED ALLOWANCES Revenue Recognition We recognize revenue using the following steps: ● Identification of the contract, or contracts, with a customer; ● Identification of the performance obligations in the contract; ● Determination of the transaction price, including the identification and estimation of variable consideration; ● Allocation of the transaction price to the performance obligations in the contract; and ● Recognition of revenue when we satisfy a performance obligation. We derive our revenues primarily from sales of generic and branded pharmaceutical products. Revenue is recognized when our obligations under the terms of our contracts with customers are satisfied, which generally occurs when control of the products we sell is transferred to the customer. We estimate variable consideration after considering applicable information that is reasonably available. We generally do not have incremental costs to obtain contracts that would otherwise not have been incurred. We do not adjust revenue for the promised amount of consideration for the effects of a significant financing component because our customers generally pay us within 100 days. All revenue recognized in the accompanying unaudited interim condensed consolidated statements of operations is considered to be revenue from contracts with customers. The following table depicts the disaggregation of revenue: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ Products and Services ​ September 30, ​ September 30, ​ September 30, ​ September 30, ​ (in thousands) 2021 2020 2021 2020 Sales of generic pharmaceutical products ​ $ 35,140 ​ $ 37,712 ​ $ 101,952 ​ $ 108,607 ​ Sales of branded pharmaceutical products ​ 14,313 ​ 12,411 ​ 32,868 ​ 32,201 ​ Sales of contract manufactured products ​ 2,382 ​ 2,152 ​ 7,277 ​ 7,026 ​ Royalties from licensing agreements ​ — ​ 339 ​ 11,210 ​ 1,120 ​ Product development services ​ 77 ​ 289 ​ 332 ​ 1,751 ​ Other ​ 149 ​ 76 ​ 1,568 ​ 518 ​ Total net revenues ​ $ 52,061 ​ $ 52,979 ​ $ 155,207 ​ $ 151,223 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ Timing of Revenue Recognition ​ September 30, ​ September 30, ​ September 30, ​ September 30, ​ (in thousands) 2021 2020 2021 2020 Performance obligations transferred at a point in time ​ $ 51,984 ​ $ 52,690 ​ $ 154,875 ​ $ 149,472 ​ Performance obligations transferred over time ​ 77 ​ 289 ​ 332 ​ 1,751 ​ Total ​ $ 52,061 ​ $ 52,979 ​ $ 155,207 ​ $ 151,223 ​ ​ In the three and nine months ended September 30, 2021 and 2020, we did not incur, and therefore did not defer, any material incremental costs to fulfill contracts. We recognized an increase of $11.0 million to net revenue from performance obligations satisfied in prior periods during the nine months ended September 30, 2021, consisting primarily of a final $11.2 million royalty revenue related to the Kite license agreement pursuant to the Tripartite Agreement as defined and described herein in Royalties from Licensing Agreements, which was partially offset by a decrease related to revised estimates for variable consideration, including chargebacks, rebates, returns, and other allowances, related to prior period sales. Revenue from Sales of Generic and Branded Pharmaceutical Products Product sales consists of sales of our generic and brand pharmaceutical products. Our sole performance obligation in our contracts is to provide pharmaceutical products to customers. Our products are sold at pre-determined standalone selling prices and our performance obligation is considered to be satisfied when control of the product is transferred to the customer. Control is generally transferred to the customer upon delivery of the product to the customer, as our pharmaceutical products are generally sold on an FOB destination basis and because inventory risk and risk of ownership passes to the customer upon delivery. Payment terms for these sales are generally less than 100 days. Sales of our pharmaceutical products are subject to variable consideration due to chargebacks, government rebates, returns, administrative and other rebates, and cash discounts. Estimates for these elements of variable consideration require significant judgment. A comprehensive discussion of variable consideration is included in Part II, Item 8. Consolidated Financial Statements, Note 1, Description of Business and Summary of Significant Accounting Policies The following table summarizes activity in the consolidated balance sheets for accruals and allowances for the nine months ended September 30, 2021 and 2020, respectively: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accruals for Chargebacks, Returns, and Other Allowances ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Administrative ​ Prompt ​ ​ ​ ​ ​ Government ​ ​ ​ ​ Fees and Other ​ Payment (in thousands) Chargebacks Rebates Returns Rebates Discounts Balance at December 31, 2019 (1) ​ $ 49,882 ​ $ 8,901 ​ $ 16,595 ​ $ 8,281 ​ $ 2,549 Accruals/Adjustments ​ 288,538 ​ 14,288 ​ 22,744 ​ 27,383 ​ 10,248 Credits Taken Against Reserve ​ (262,531) ​ ​ (11,511) ​ (16,089) ​ (27,287) ​ (9,442) Balance at September 30, 2020 (1) ​ $ 75,889 ​ $ 11,678 ​ $ 23,250 ​ $ 8,377 ​ $ 3,355 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at December 31, 2020 (1) ​ $ 88,746 ​ $ 7,826 ​ $ 27,155 ​ $ 8,906 ​ $ 3,839 Accruals/Adjustments ​ 343,117 ​ 31,515 ​ 16,043 ​ 74,594 ​ 31,138 Credits Taken Against Reserve ​ (333,867) ​ ​ (27,628) ​ (10,969) ​ (75,877) ​ (30,876) Balance at September 30, 2021 (1) ​ $ 97,996 ​ $ 11,713 ​ $ 32,229 ​ $ 7,623 ​ $ 4,101 (1) Chargebacks are included as an offset to accounts receivable in the unaudited condensed consolidated balance sheets. Administrative Fees and Other Rebates and Prompt Payment Discounts are included as an offset to accounts receivable or as accrued expenses and other in the unaudited condensed consolidated balance sheets. Returns are included in returned goods reserve in the unaudited condensed consolidated balance sheets. Government Rebates are included in accrued government rebates in the unaudited condensed consolidated balance sheets. Contract Manufacturing Product Sales Revenue Contract manufacturing arrangements consist of agreements in which we manufacture a pharmaceutical product on behalf of a third party. Our performance obligation is to manufacture and provide pharmaceutical products to customers, typically pharmaceutical companies. The contract manufactured products are sold at pre-determined standalone selling prices and our performance obligations are considered to be satisfied when control of the product is transferred to the customer. Control is transferred to the customer when the product leaves our dock to be shipped to the customer, as our contract manufactured pharmaceutical products are sold on an FOB shipping point basis and the inventory risk and risk of ownership passes to the customer at that time. Payment terms for these sales are generally fewer than two months. We estimate returns based on historical experience. Historically, we have not had material returns for contract manufactured products. As of September 30, 2021, the aggregate amount of the transaction price allocated to the remaining performance obligations for all open contract manufacturing customer contracts was $3.0 million, which consists of firm orders for contract manufactured products. We will recognize revenue for these performance obligations as they are satisfied, which is anticipated within six months . Royalties from Licensing Agreements From time to time, we enter into transition agreements with the sellers of products we acquire, under which we license to the seller the right to sell the acquired products. Therefore, we recognize the revenue associated with sales of the underlying products as royalties. Because these royalties are sales-based, we recognize the revenue when the underlying sales occur, based on sales and gross profit information received from the sellers. Upon full transition of the products and upon launching the products under our own labels, we recognize revenue for the products as sales of generic or branded pharmaceutical products, as described above. From time to time, we enter into supply and distribution agreements with contract manufacturing customers, under which we license to the contract manufacturing customer the right to sell our products, and we are entitled to a royalty on sales made by the contract manufacturing customer under these arrangements. Therefore, we recognize the revenue associated with sales of the underlying products as royalties. Because these royalties are sales-based, we recognize the revenue when the underlying sales occur, based on sales and gross profit information received from the contract manufacturing customers. Pursuant to a 2012 Tripartite Agreement (the “Tripartite Agreement”) between the Company, The Regents of the University of California (“The Regents”), and Cabaret Biotech Ltd., an Israeli corporation (“Cabaret”) (as assignee of Dr. Zelig Eshhar’s rights under the Tripartite Agreement), and subsequent amendments thereto and assignments thereof, we were entitled to receive a percentage of the milestone and sales royalty payments paid to Cabaret by Kite Pharma, Inc. (“Kite”), a subsidiary of Gilead Sciences, Inc., under a license agreement. Under such license agreement, Kite licensed from Dr. Eshhar and Cabaret the patent rights covered by the Tripartite Agreement and agreed to make certain payments to Cabaret based on, among other things, Kite’s sales of Yescarta®. Under the Tripartite Agreement, portions of these payments were to be distributed to The Regents and to us. ​ Historically, we recorded royalty income related to Yescarta® on an accrual basis utilizing our best estimate of royalties earned based upon information available in the public domain, our understanding of the various agreements governing the royalty, and other information received from time to time from the relevant parties. Generally, cash was received directly from Cabaret once a year. The agreements governing this royalty were subject to multiple actions in multiple jurisdictions, including litigation between Cabaret and Kite, and separately, ANI and Cabaret. In the first quarter of 2021, we became aware that the litigation between Cabaret and Kite was dismissed. In April 2021, Cabaret and the Company settled all amounts due for amounts actually received by Cabaret or Eshhar for the licensing or use of the patent rights governed by the Kite license agreement. As a result, we recognized million, which has been recorded as other expense, net in the accompanying unaudited interim condensed consolidated statement of operations, related to certain legal expenditures incurred. We received final payment from Cabaret in May 2021. Based upon the events that led to the dismissal of the litigation between Cabaret and Kite, the Company does not expect to receive any future royalty income related to the Kite license agreement. In conjunction with payment of amounts due to us, all outstanding litigation between the Company and Cabaret were dismissed. Product Development Services Revenue We provide product development services to customers, which are performed over time. These services primarily relate to the technical transfer of product development to our facility in Oakville, Ontario. The duration of these technical transfer projects can be up to three years. Deposits received from these customers are recorded as deferred revenue until revenue is recognized. For contracts with no deposits and for the remainder of contracts with deposits, we invoice customers as our performance obligations are satisfied. We recognize revenue on a percentage of completion basis, which results in contract assets on our balance sheet. As of September 30, 2021, the aggregate amount of the transaction price allocated to the remaining performance obligations for all open product development services contracts was $0.4 million. We expect to satisfy these performance obligations within the next six months. Credit Concentration Our customers are primarily wholesale distributors, chain drug stores, group purchasing organizations, and pharmaceutical companies. ​ During the three and nine months ended September 30, 2021 and 2020 we had three customers that accounted for 10% or more of net revenues. As of September 30, 2021, accounts receivable from these customers totaled 85% of accounts receivable, net. ​ The three customers represent the total percentage of net revenues as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ Nine Months Ended ​ ​ ​ September 30, ​ ​ September 30, ​ ​ September 30, ​ ​ September 30, ​ ​ 2021 ​ 2020 ​ 2021 2020 Customer 1 ​ 31 % ​ 30 % ​ 29 % ​ 31 % Customer 2 ​ 23 % ​ 25 % ​ 22 % ​ 24 % Customer 3 ​ 17 % ​ 19 % ​ 15 % ​ 19 % 3. ​

PENDING BUSINESS COMBINATION
PENDING BUSINESS COMBINATION	3. On March 8, 2021, we entered into a definitive agreement to acquire Novitium Pharma LLC (“Novitium”), a privately held New Jersey-based pharmaceutical company with development, manufacturing, and commercial capabilities (the “Acquisition”). The closing of the Acquisition will occur (a) within five business days after all of the conditions to the closing set forth in the merger agreement are satisfied or waived or (b) at such other time, date and place as may be agreed by us and Novitium, subject to the completion of a minimum period. The closing is subject to the satisfaction of customary closing conditions and necessary regulatory approvals. ​ Consideration will consist of a combination of (i) an estimated cash amount of $89.5 million, subject to various adjustments and expected to be financed by a $25.0 million private placement of preferred stock (the “PIPE Investment”) and by new debt financing, both described below, (ii) an aggregate of 2,466,667 shares of ANI common stock, and (iii) up to $46.5 million in contingent future earn-out payments. ​ We will finance the transaction with a new $340.0 million Senior Secured Credit Facility (the “New Facility”), consisting of a $300.0 million term loan and a $40.0 million revolving credit facility, the issuance of 2,466,667 shares of ANI common stock (approximately $74.0 million in value based on a $30.00 stock price) (the “Stock Consideration”), and a $25.0 million PIPE Investment by Ampersand 2020 Limited Partnership (“Ampersand”), an affiliate of Ampersand Capital Partners of which ANI’s Chairman of the Board is an operating partner and as such Ampersand is a related party. At closing, we intend to use the proceeds from the New Facility to fund a portion of the Acquisition and repay all of the outstanding debt under the existing senior secured credit facility discussed in Note 4. ​ The New Facility will be secured by substantially all the assets of ANI and its subsidiaries and used for the cash portion of the acquisition and to refinance ANI’s existing senior credit facilities. The term loan portion of the New Facility, which was successfully syndicated on May 24, 2021, represents fully committed capital and, as such, carries a customary ticking fee that commences 45 days and 90 days post allocation. During the three and nine months ended September 30, 2021, we incurred $2.4 million in expense related to the ticking fee, all of which was recognized as other expense, net, on the unaudited interim condensed consolidated statement of operations. Amounts drawn on the $300.0 million term loan will bear an interest rate equal to 1-month LIBOR rate plus an applicable margin of 6.00% per annum, or an alternative base rate plus an applicable base rate margin of 5.00% per annum. Amounts drawn on the $40.0 million revolving credit facility will bear an interest rate equal to 1-month LIBOR rate plus an applicable margin of 4.75% per annum, or an alternative base rate plus an applicable base rate margin of 3.75% per annum. On the revolving credit facility, we will incur a commitment fee on any unused portion at a rate of 0.50% per annum. ​ As discussed in Note 5, we currently have an interest rate swap to manage our exposure to changes in LIBOR-based interest rates underlying total borrowings under our Term Loan and DDTL. We intend to retain an interest rate swap with similar structure and terms in order to manage our exposure to changes in LIBOR-based interest rates underlying a portion of borrowings under the New Facility. ​ Concurrently with the execution of the definitive agreement, on March 8, 2021, we entered into an Equity Commitment and Investment Agreement with Ampersand (the “PIPE Investor”), pursuant to which we agreed to issue and sell to the PIPE Investor, and the PIPE Investor agreed to purchase, 25,000 shares of our Series A Convertible Preferred Stock (the “PIPE Shares”), for a purchase price of $1,000 per share and an aggregate purchase price of $25.0 million PIPE Investment. The issuance of shares of ANI common stock into which PIPE Shares will be convertible and the Stock Consideration for the Acquisition were approved by the ANI stockholders in June 2021. ​ During the three and nine months ended September 30, 2021, we incurred $0.5 million and $5.1 million, respectively, in transaction costs related to this pending Acquisition, all of which were expensed and recognized as selling, general, and administrative expenses on the unaudited interim condensed consolidated statements of operations. ​ ​

INDEBTEDNESS	4. INDEBTEDNESS Credit Facility Our five-year Senior Secured Credit Facility (the “Credit Facility”) is comprised of a $72.2 million term loan (the “Term Loan”), a $118.0 million delayed draw term loan (“DDTL”), and a $75.0 million revolving credit facility (the “Revolver”), all of which mature in December 2023. The Credit Facility has a subjective acceleration clause in case of a material adverse event. The Term Loan includes a repayment schedule, pursuant to which $6.8 million of the loan will be paid in quarterly installments during the 12 months ending September 30, 2022. As of September 30, 2021, $6.8 million of the Term Loan is recorded as current borrowings in the consolidated balance sheets. The DDTL includes a repayment schedule, pursuant to which $9.6 million will be paid in quarterly installments during the 12 months ending September 30, 2022. As of September 30, 2021, $9.6 million of the DDTL is recorded as current borrowings in the consolidated balance sheets. As of September 30, 2021, there is $31.5 million outstanding and payable on our Revolver, all of which is recorded as a long-term borrowing on the consolidated balance sheets. As of September 30, 2021, $43.5 million remained available for borrowing under the Revolver. Amounts drawn on the Term Loan, DDTL, and Revolver bear an interest rate equal to, at our option, either a 1-month LIBOR rate plus 1.50% to 2.75% per annum, depending on our total leverage ratio or an alternative base rate plus an applicable base rate margin, which varies within a range of 0.50% to 1.75% , depending on our total leverage ratio. On the Revolver, we incur a commitment fee at a rate per annum that varies within a range of 0.25% to 0.50% , depending on our leverage ratio. As of September 30, 2021, our interest rate on outstanding borrowings was 1-month LIBOR plus 2.00% and our commitment fee rate was 0.4% . The Credit Facility is secured by a lien on substantially all of ANI Pharmaceuticals, Inc.’s and its principal domestic subsidiary’s assets and any future domestic subsidiary guarantors’ assets. The Credit Facility is subject to customary financial and nonfinancial covenants. The carrying value of the current and non-current components of the Term Loan and DDTL as of September 30, 2021 and December 31, 2020 are: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Current ​ ​ September 30, ​ December 31, (in thousands) 2021 2020 Current borrowing on debt ​ $ 16,355 $ 13,691 Deferred financing costs ​ (428) ​ (448) Current debt, net of deferred financing costs ​ $ 15,927 ​ $ 13,243 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-Current ​ ​ September 30, ​ December 31, (in thousands) 2021 2020 Non-current borrowing on debt ​ $ 155,057 ​ $ 165,755 Deferred financing costs ​ (494) ​ (812) Non-current debt, net of deferred financing costs and current component ​ $ 154,563 ​ $ 164,943 ​ As of September 30, 2021, we had a $62.3 million balance on the Term Loan, $109.2 million balance on the DDTL, and $31.5 million balance on the Revolver.

DERIVATIVE FINANCIAL INSTRUMENT AND HEDGING ACTIVITY
DERIVATIVE FINANCIAL INSTRUMENT AND HEDGING ACTIVITY	5. DERIVATIVE FINANCIAL INSTRUMENT AND HEDGING ACTIVITY At times we use derivative financial instruments to hedge our exposure to interest rate risks. All derivative financial instruments are recognized as either assets or liabilities at fair value on the consolidated balance sheet and are classified as current or non-current based on the scheduled maturity of the instrument. When we enter into a hedge arrangement and intend to apply hedge accounting, we formally document the hedge relationship and designate the instrument for financial reporting purposes as a fair value hedge, a cash flow hedge, or a net investment hedge. When we determine that a derivative financial instrument qualifies as a cash flow hedge and is effective, the changes in fair value of the instrument are recorded in accumulated other comprehensive loss, net of tax in our consolidated balance sheets and will be reclassified to earnings when the hedged item affects earnings. In December 2018, we refinanced our previous credit agreement and, at the same time, entered into an interest rate swap, which was considered a derivative financial instrument, with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our Term Loan. In February 2019, we entered into an interest rate swap, which was considered a derivative financial instrument, with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying our DDTL. The hedges had been designated as effective cash flow hedges and qualified for hedge accounting. The interest rate swaps related to the Term Loan and DDTL had a weighted average fixed rate of 2.60% and 2.47%, respectively, with a maturity in December 2023. In April 2020, we terminated the remaining $184.2 million notional value of these interest rate swaps and are recognizing the net loss in accumulated other comprehensive loss at the time of the termination to interest expense over the remaining terms through December 2023. At the same time in April 2020, we entered into an interest rate swap with Citizens Bank, N.A. to manage our exposure to changes in LIBOR-based interest rates underlying total borrowings under our Term Loan and DDTL. The interest rate swap matures in December 2026. As of September 30, 2021, the notional amount of the interest rate swap was $171.4 million and decreases in line with maturities of our Term Loan and DDTL until December 2023, after which it remains static until maturity in 2026. The interest rate swap provides an effective fixed rate of 1.99% and has been designated as an effective cash flow hedge and therefore qualifies for hedge accounting. The interest rate swap effectively provides a fixed rate of interest throughout the life of our Term Loan and DDTL. As of September 30, 2021, the fair value of the interest rate swap liability was valued at $7.9 million and was recorded in derivatives and other non-current liabilities in the accompanying unaudited interim condensed consolidated balance sheets. As of September 30, 2021, $4.2 million was recorded in accumulated other comprehensive loss, net of tax in the accompanying unaudited interim condensed consolidated balance sheets. ​ During the three and nine months ended September 30, 2021, the change in the fair value of the interest rate swap of $0.6 million, net of $0.3 million of tax and $4.7 million, net of $0.2 million of tax, was recorded in accumulated other comprehensive income, net of tax in our unaudited interim condensed consolidated statements of comprehensive income/(loss). Differences between the hedged 1-month LIBOR rate and the fixed rate are recorded as interest expense in the same period that the related interest is recorded for the Term Loan and DDTL based on the 1-month LIBOR rate. In the three and nine months ended September 30, 2021, $1.3 million and $3.7 million of interest expense was recognized in relation to the interest rate swap, respectively.

EARNINGS (LOSS) PER SHARE
EARNINGS (LOSS) PER SHARE	6. EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. For periods of net income, and when the effects are not anti-dilutive, we calculate diluted earnings (loss) per share by dividing net income available to common shareholders by the weighted-average number of shares outstanding plus the impact of all potential dilutive common shares, consisting primarily of common stock options, shares to be purchased under our Employee Stock Purchase Plan (“ESPP”), unvested restricted stock awards, and stock purchase warrants, using the treasury stock method. For periods of net loss, diluted loss per share is calculated similarly to basic loss per share. Our unvested restricted shares contain non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic and diluted earnings (loss) per share excludes from the numerator net income (but not net loss) attributable to the unvested restricted shares, and excludes the impact of those shares from the denominator. Earnings (loss) per share for the three and nine months ended September 30, 2021 and 2020 are calculated for basic and diluted earnings (loss) per share as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ Diluted ​ Basic ​ Diluted ​ (in thousands, except per share amounts) ​ Three Months Ended September 30, ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2021 2020 2021 2020 2021 2020 2021 2020 Net (loss)/income ​ $ (4,447) ​ $ 434 ​ $ (4,447) ​ $ 434 ​ $ (18,467) ​ $ (18,913) ​ $ (18,467) ​ $ (18,913) ​ Net income allocated to restricted stock ​ — ​ (12) ​ — ​ (13) ​ — ​ — ​ — ​ — ​ Net (loss)/income allocated to common shares ​ $ (4,447) ​ $ 422 ​ $ (4,447) ​ $ 421 ​ $ (18,467) ​ $ (18,913) ​ $ (18,467) ​ $ (18,913) ​ Basic Weighted-Average Shares Outstanding ​ 12,107 ​ 11,991 ​ 12,107 ​ 11,991 ​ 12,066 ​ 11,953 ​ 12,066 ​ 11,953 ​ Dilutive effect of stock options and ESPP ​ ​ ​ ​ ​ ​ ​ — ​ 12 ​ ​ ​ ​ ​ ​ ​ — ​ — ​ Diluted Weighted-Average Shares Outstanding ​ ​ ​ ​ ​ ​ ​ 12,107 ​ 12,003 ​ ​ ​ ​ ​ ​ ​ 12,066 ​ 11,953 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Loss)/Income per share ​ $ (0.37) ​ $ 0.04 ​ $ (0.37) ​ $ 0.04 ​ $ (1.53) ​ $ (1.58) ​ $ (1.53) ​ $ (1.58) ​ ​ The number of anti-dilutive shares, which have been excluded from the computation of diluted earnings (loss) per share, was 1.6 million and 1.1 million for the three months ended September 30, 2021 and 2020, and was 1.7 million and 1.3 million for the nine months ended September 30, 2021 and 2020, respectively. For the three months ended September 30, 2021 and the nine months ended September 30, 2021 and 2020, all potentially dilutive shares were anti-dilutive and excluded from the calculation of diluted loss per share because we recognized a net loss. For the three months ended September 30, 2020, anti-dilutive shares consist of out-of-the-money Class C Special stock, out-of-the-money common stock options, and unvested restricted stock awards and common stock options that are anti-dilutive when calculating the impact of the potential dilutive common shares using the two-class or treasury stock method.

As a result, we are dependent upon our current vendors to reliably supply the API required for on-going product manufacturing. During the three and nine months ended September 30, 2021, no single vendor represented at least 10% of inventory purchases. During the three months ended September 30, 2020, we purchased approximately 14% of our inventory from one supplier.

We assess the recoverability of the carrying value of goodwill as of October 31 st Definite-lived Intangible Assets The components of net definite-lived intangible assets are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 ​ December 31, 2020 ​ Weighted Average ​ ​ Gross Carrying ​ Accumulated ​ Gross Carrying ​ Accumulated ​ Amortization (in thousands) Amount Amortization Amount Amortization Period Acquired ANDA intangible assets ​ $ 106,415 ​ $ (51,684) ​ $ 106,415 ​ $ (42,367) 8.8 years NDAs and product rights ​ 242,372 ​ (132,146) ​ 230,974 ​ (112,483) 9.9 years Marketing and distribution rights ​ 17,157 ​ (12,107) ​ 17,157 ​ (11,386) 5.7 years Non-compete agreement ​ 624 ​ (490) ​ 624 ​ (423) 7.0 years ​ ​ $ 366,568 ​ $ (196,427) ​ $ 355,170 ​ $ (166,659) ​ 9.4 years ​ Definite-lived intangible assets are stated at cost, net of amortization, generally using the straight-line method over the expected useful lives of the intangible assets. In the case of certain New Drug Application (“NDA”) and product rights assets, we use an accelerated amortization method to better match the anticipated economic benefits expected to be provided. Amortization expense was $10.1 million for the three months ended September 30, 2021 and 2020. Amortization expense was $29.8 million and $30.2 million for the nine months ended September 30, 2021 and 2020, respectively. Refer to Note 12 for more details on acquired definite-lived intangible assets. We test for impairment of definite-lived intangible assets when events or circumstances indicate that the carrying value of the assets may not be recoverable. No such triggering events were identified during the three and nine months ended September 30, 2021 and 2020 and therefore no impairment loss was recognized in the three and nine months ended September 30, 2021 and 2020. Expected future amortization expense is as follows: ​ ​ ​ ​ ​ (in thousands) ​ ​ 2021 ​ $ 10,057 2022 ​ 36,828 2023 ​ 36,080 2024 ​ 33,103 2025 ​ 29,755 2026 and thereafter ​ 24,318 Total ​ $ 170,141 ​

INCOME TAXES

INCOME TAXES	9 Months Ended
	Sep. 30, 2021
INCOME TAXES
INCOME TAXES	10. INCOME TAXES We use the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that such tax rate changes are enacted. The measurement of a deferred tax asset is reduced, if necessary, by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. As of September 30, 2021, we have provided a valuation allowance against consolidated net deferred tax assets of $0.4 million, related solely to deferred tax assets for net operating loss carryforwards in certain U.S. state jurisdictions. We use a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. We have not identified any uncertain income tax positions that could have a material impact on the consolidated financial statements. We recognize interest and penalties accrued on any unrecognized tax exposures as a component of income tax expense; we did not have any such amounts accrued as of September 30, 2021 and December 31, 2020. We are subject to taxation in various U.S. jurisdictions and all of our income tax returns remain subject to examination by tax authorities due to the availability of NOL carryforwards. For interim periods, we recognize an income tax provision/(benefit) based on our estimated annual effective tax rate, calculated on a worldwide consolidated basis, expected for the entire year. The interim annual estimated effective tax rate is based on the statutory tax rates then in effect, as adjusted for estimated changes in temporary and estimated permanent differences, and excludes certain discrete items whose tax effect, when material, is recognized in the interim period in which they occur. These changes in temporary differences, permanent differences, and discrete items result in variances to the effective tax rate from period to period. We also have elected to exclude the impacts from significant pre-tax non-recognized subsequent events from our interim estimated annual effective rate until the period in which they occur. Prior to the adoption of new accounting guidance that we adopted on a prospective basis on January 1, 2021, during periods when we incurred net losses before income taxes, our annual estimated effective tax rate was at times adjusted based on the “loss limitation” requirements applicable to interim tax provisions, resulting in a limited income tax benefit recognized in that period. Under these provisions, our income tax benefit for the three months ended March 31, 2020 (but not for the three and nine month periods ended September 30, 2020) was limited. The “loss limitation” requirements were removed by the new accounting guidance and, therefore, we were not required to assess any such limitation for 2021. Our estimated annual effective tax rate changes throughout the year as our on-going estimates of pre-tax income, changes in temporary differences, and permanent differences are revised, and as discrete items occur. Global Intangible Low-Taxed Income (“GILTI”), as defined in the Tax Cuts and Jobs Act of 2017, generated from our Canadian operations is subject to U.S. taxes, with certain defined exemptions, thresholds and credits. For financial reporting purposes we have elected to treat GILTI inclusions as a period cost. For the three months ended September 30, 2021, we recognized an income tax benefit of $2.7 million. The income tax benefit resulted from applying an estimated annual worldwide effective tax benefit rate of 37.6% to pre-tax consolidated loss of $7.1 million reported during the period, as well as the net effects of certain discrete items occurring which impact our income tax provision in the period in which they occur. There were no material discrete items occurring during the three months ended September 30, 2021. For the three months ended September 30, 2020, we recognized an income tax benefit of $0.4 million. The income tax benefit for this period is the incremental benefit generated from applying the estimated annual worldwide effective tax benefit rate of 19.8% to consolidated pre-tax losses for the nine months ended September 30, 2020 as compared to the consolidated income tax benefit as of June 30, 2020. The estimated annual effective rate varies from the statutory rate as a result of permanent differences as well as the net effects of certain discrete items occurring which impact our income tax provision in the period in which they occur. There were no material discrete items during the three months ended September 30, 2020. For the nine months ended September 30, 2021, we recognized an income tax benefit of $6.7 million. The income tax benefit resulted from applying an estimated annual worldwide effective tax benefit rate of 26.7% to pre-tax consolidated loss of $25.2 million reported during the period, as well as the net effects of certain discrete items occurring which impact our income tax provision in the period in which they occur. There were no material discrete items occurring during the nine months ended September 30, 2021. For the nine months ended September 30, 2020, we recognized an income tax benefit of $4.7 million. The income tax benefit resulted from applying an estimated annual worldwide effective tax benefit rate of 19.8% to pre-tax consolidated loss of $23.6 million reported during the period, as well as the net effects of certain discrete items occurring which impact our income tax provision in the period in which they occur. There were no material discrete items during the nine months ended September 30, 2020.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	11. COMMITMENTS AND CONTINGENCIES Operating Leases All our existing leases as of September 30, 2021 are classified as operating leases. As of September 30, 2021, we have nine material operating leases for facilities and office equipment with remaining terms expiring from 2022 through 2026 and a weighted average remaining lease term of 2.5 years. Many of our existing leases have fair value renewal options, none of which are considered certain of being exercised or included in the minimum lease term. Discount rates used in the calculation of our lease liability ranged between 3.99% and 8.95%. Rent expense for the three and nine months ended September 30, 2021 and 2020 consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 ​ 2020 Operating lease costs ​ $ 40 ​ $ 57 ​ $ 132 ​ $ 166 Variable lease costs ​ 9 ​ 15 ​ 30 ​ 44 Total lease costs ​ $ 49 ​ $ 72 ​ $ 162 ​ $ 210 ​ A maturity analysis of our operating leases follows: ​ ​ ​ ​ ​ (in thousands) ​ ​ Future payments: ​ ​ ​ 2021 ​ $ 35 2022 ​ 127 2023 ​ 82 2024 ​ 56 2025 and thereafter ​ 42 Total ​ $ 342 ​ ​ ​ ​ Discount ​ ​ (22) Lease liability ​ ​ 320 Current lease liability ​ ​ (130) Non-current lease liability ​ $ 190 ​ Government Regulation Our products and facilities are subject to regulation by a number of federal and state governmental agencies, such as the Drug Enforcement Administration (“DEA”), the U.S. Food and Drug Administration (“FDA”), the Centers for Medicare and Medicaid Services (“CMS”), and Health Canada. The FDA, in particular, maintains oversight of the formulation, manufacture, distribution, packaging, and labeling of all of our products. The DEA and Health Canada maintain oversight over our products that are considered controlled substances. Unapproved Products Two of our products, Esterified Estrogen with Methyltestosterone (“EEMT”) and Opium Tincture, are marketed without approved NDAs or Abbreviated New Drug Applications (“ANDAs”). During the three months ended September 30, 2021 and 2020, net revenues for these products totaled $4.2 million and $4.3 million, respectively. During the nine months ended September 30, 2021 and 2020, net revenues for these products totaled $12.2 million and $12.4 million, respectively. In addition, one group of products that we manufacture on behalf of a contract customer is marketed by that customer without an approved NDA. If the FDA took enforcement action against such customer, the customer may be required to seek FDA approval for the group of products or withdraw them from the market. Our contract manufacturing revenues for the group of unapproved products for the three months ended September 30, 2021 and 2020 were $0.7 million. Our contract manufacturing revenues for the group of unapproved products for the nine months ended September 30, 2021 and 2020 were $2.1 million and $2.3 million, respectively. Legal Proceedings We are involved, and from time to time may become involved, in various disputes, governmental and/or regulatory inquiries, investigations, government reimbursement related actions and litigation. These matters are complex and subject to significant uncertainties. As such, we cannot accurately predict the outcome, or the effects of the legal proceedings described below. While we believe that we have valid claims and/or defenses in the litigation and other matters described below, litigation is inherently unpredictable, and the outcome of the proceedings could result in losses, including substantial damages, fines, civil or criminal penalties and injunctive or administrative remedies. We intend to vigorously prosecute and/or defend these matters, as appropriate, however, from time to time, we may settle or otherwise resolve these matters on terms and conditions that we believe are in our best interests. Resolution of any or all claims, investigations, and legal proceedings, individually or in the aggregate, could have a material adverse effect on our results of operations and/or cash flows in any given accounting period or on our overall financial condition. Some of these matters with which we are involved are described below, and unless otherwise disclosed, we are unable to predict the outcome of the matter or to provide an estimate of the range of reasonably possible material losses. We record accruals for loss contingencies to the extent we conclude it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. From time to time, we are also involved in other pending proceedings for which, in our opinion based upon facts and circumstances known at the time, either the likelihood of loss is remote or any reasonably possible loss associated with the resolution of such proceedings is not expected to be material to our results, and therefore remain undisclosed. If and when any reasonably possible losses associated with the resolution of such other pending proceedings, in our opinion, become material, we will disclose such matters. Furthermore, like all pharmaceutical manufacturers, we are periodically exposed to product liability claims. The prevalence of these claims could limit our coverage under future insurance policies or cause those policies to become more expensive, which could harm our business, financial condition, and operating results. Recent trends in the product liability and director and officer insurance markets is to exclude matters related to certain classes of drugs. Our policies have been subject to such exclusions which place further potential risk of financial loss on us. Legal fees for litigation-related matters are expensed as incurred and included in the consolidated statements of operations under the selling, general, and administrative expense line item. Commercial Litigation In November of 2017, we were served with a complaint filed by Arbor Pharmaceuticals, LLC, in the United States District Court for the District of Minnesota. The complaint alleged false advertising and unfair competition in violation of Section 43(a) of the Lanham Act, Section 1125(a) of Title 15 of the United States Code, and Minnesota State law, under the premise that we sold an unapproved Erythromycin Ethylsuccinate (“EES”) product during the period between September 27, 2016 and November 2, 2018. The complaint sought a trial by jury and monetary damages (inclusive of actual and consequential damages, treble damages, disgorgement of ANI profits, and legal fees) of an unspecified amount. Discovery in this action closed on March 31, 2019 and trial was scheduled to commence on August 25, 2021. On August 3, 2021, the Company entered into a Settlement Agreement with Arbor Pharmaceuticals, LLC to resolve all claims related to Civil Action 17-4910, Arbor Pharmaceuticals, LLC (“Arbor”) v. ANI Pharmaceuticals, Inc., which was pending trial in the United States District Court for the District of Minnesota. Under the terms of the agreement, ANI paid Arbor $8.4 million and Arbor dismissed the action with prejudice. Neither party admitted wrongdoing in reaching this settlement. The Company paid the settlement from cash on the balance sheet. On December 3, 2020, class action complaints were filed against the Company on behalf of putative classes of direct and indirect purchasers of the drug Bystolic. On December 23, 2020, six individual purchasers of Bystolic, CVS, Rite Aid, Walgreen, Kroger, Albertsons, and H-E-B, filed complaints against the Company. On March 15, 2021, the plaintiffs in these actions filed amended complaints. All amended complaints are substantively identical. The plaintiffs in these actions allege that, beginning in 2012, Forest Laboratories, the manufacturer of Bystolic, entered into anticompetitive agreements when settling patent litigation related to Bystolic with seven potential manufacturers of a generic version of Bystolic: Hetero, Torrent, Alkem/Indchemie, Glenmark, Amerigen, Watson, and various of their corporate parents, successors, subsidiaries, and affiliates. ANI itself was not a party to patent litigation with Forest concerning Bystolic and did not settle patent litigation with Forest. The plaintiffs named the Company as a defendant based on the Company’s January 8, 2020 Asset Purchase Agreement with Amerigen. The complaints allege that the 2013 patent litigation settlement agreement between Forest and Amerigen violates federal and state antitrust laws and state consumer protection laws by delaying the market entry of generic versions of Bystolic. Plaintiffs allege they paid higher prices as a result of delayed generic competition. Plaintiffs seek damages, trebled or otherwise multiplied under applicable law, injunctive relief, litigation costs and attorneys’ fees. The complaints do not specify the amount of damages sought from the Company or other defendants and the Company at this early stage of the litigation cannot reasonably estimate the potential damages that the plaintiffs will seek. The cases have been consolidated in the United States District Court for the Southern District of New York On March 24, 2021, Azurity Pharmaceuticals, Inc. (“Azurity”) filed a complaint in the United States District Court for the District of Minnesota against ANI Pharmaceuticals, Inc., asserting that ANI’s vancomycin hydrochloride oral solution drug product infringes U.S. Patent No. 10,688,046. The complaint seeks injunctive relief, damages, including lost profits and/or royalty, treble damages, and attorneys’ fee and costs. ANI filed its answer on August 31, 2021, and is currently engaged in discovery. ANI intends to dispute any and all liability in this case. ​ On April 1, 2021, United Therapeutics Corp. and Supernus Pharmaceuticals, Inc. (“UTC/Supernus”) filed a complaint in the United States District Court for the District of Delaware against ANI Pharmaceuticals, Inc., asserting that ANI's proposed Treprostinil extended release drug product, which is subject to ANI’s Abbreviated New Drug Application No. 215667, infringes U.S. Patent Nos. 7,417,070, 7,544,713, 8,252,839, 8,349,892, 8,410,169, 8,747,897, 9,050,311, 9,278,901, 9,393,203, 9,422,223, 9,593,066 and 9,604,901 (“the Asserted Patents”). The complaint seeks injunctive relief , attorneys' fee and costs. ANI filed its answer and counterclaims on May 28, 2021, denying UTC/Supernus’ allegations and seeking declaratory judgment that ANI has not infringed any valid and enforceable claim of the Asserted Patents, that the Asserted Patents are invalid, and an award of attorneys’ fees and costs. Trial is set for May 8, 2023. ​ Industry Related Litigation In July 2020, we were served with a complaint brought by the Office of the Attorney General of the State of New Mexico against manufacturers and sellers of ranitidine products. The complaint asserts a public nuisance claim and a negligence claim against the generic ranitidine manufacturer defendants, including the Company. The public nuisance claim asserts that the widespread sale of ranitidine products in the state created a public nuisance that requires a state-wide medical monitoring program of New Mexico residents for the development of colorectal cancer, stomach cancer, gastrointestinal disorders and liver disease. As damages, New Mexico asks that the defendants fund this medical monitoring program. The negligence claims assert that the defendants were negligent in selling the product, essentially alleging that it was unreasonable to have the product on the market. With respect to that claim, New Mexico asserts that it paid for ranitidine products through state-funded insurance and health-care programs. On December 15, 2020, the case was removed to federal court and transferred to the In re Zantac multidistrict litigation (“MDL”) pending in the United States District Court for the Southern District of Florida. New Mexico moved for remand to state court. The MDL court granted the remand motion on February 25, 2021. On April 16, 2021, New Mexico filed an amended complaint in the New Mexico First Judicial District Court in Santa Fe County. It did not name ANI in the amended complaint, effectively voluntarily dismissing ANI from the action. In December 2020, the City of Baltimore served ANI with a complaint against manufacturers and sellers of ranitidine products. The City of Baltimore complaint tracks the allegations of the New Mexico complaint. The Baltimore action was removed to federal court and transferred to the In re Zantac MDL on February 1, 2021. The City of Baltimore moved for remand, which was granted on April 1, 2021. The parties stipulated to allow the City of Baltimore to file an amended complaint in the Circuit Court of Maryland for Baltimore City in “due course,” without a specific filing deadline. On June 23, 2021, the City of Baltimore filed an amended complaint. The City of Baltimore did not name ANI in its amended complaint, effectively voluntarily dismissing ANI from the action. We dispute any liability in these matters. ​ Product Liability Related Litigation All manufacturers of the drug Reglan and its generic equivalent metoclopramide, including ANI, have faced allegations from plaintiffs in various states claiming bodily injuries as a result of ingestion of metoclopramide or its brand name, Reglan, prior to the FDA’s February 2009 Black Box warning requirement (“legacy claims”). All these original legacy claims were settled or closed out, including a series of claims in California that were resolved by coordinated proceeding and settlement. Our insurance company assumed the defense of the legacy claims and paid all losses in settlement of the California legacy claims. In March 2019, we were served with a lawsuit in the Superior Court of California, County of Riverside, adding us as a defendant in a complaint filed in July 2017 that is alleged not to have been part of the original settled legacy claims. This new claim was dismissed with prejudice in July 2021 and the matter is now closed. ​ In June 2020, we were served with a personal injury complaint in the case of Koepsel v. Boehringer Ingelheim Pharmaceuticals, et al., MDL No. 20-MD-2924, Case No. 9:20-cv-80882-RLR, filed in the United States District Court for Southern District of Florida, in which the plaintiff alleges that he developed kidney cancer in 2018 as a result of taking over the counter medication containing ranitidine. The Koepsel action was filed within an existing multidistrict litigation concerning ranitidine-containing drugs pending in the Southern District of Florida before Judge Robin L. Rosenberg, In re Zantac MDL, 20 MDL 2924. A Master Personal Injury Complaint (“MPIC”) in that MDL that was filed on June 22, 2020 also named the Company as a defendant. The Company was dismissed from the Koepsel case on August 21, 2020 and was dismissed from the MPIC on September 8, 2020. On December 31, 2020, after ANI was dismissed, the district court dismissed the MPIC claims against generic manufacturer defendants partially with prejudice and partially with leave to replead. The failure to warn and design defect claims were dismissed with prejudice on preemption grounds. An Amended Master Personal Injury Complaint was filed on February 8, 2021, which does not name ANI. The Company has been named in other individual personal injury complaints filed in MDL 20 MD 2924 in which plaintiffs allege that they developed cancer after taking prescription and over the counter medication containing ranitidine. To date, the Company has been served with complaints in five of those additional cases: Cooper v. Boehringer Ingelheim Pharmaceuticals, et al., MDL No. 20-MD-2924, Case No. 9:20-cv-81130-RLR (served September 30, 2020), Lineberry v. Amneal Pharmaceuticals, LLC, et al., MDL No. 20-MD-2924, Case No. 9:20-cv-81079-RLR (served August 20, 2020), Lovette v. Amneal Pharmaceuticals, LLC, et al., MDL No. 20-MD-2924, Case No. 9:20-cv-81040-RLR (served August 26, 2020), Hightower v. Pfizer, et al, MDL No. 20-MD-2924, Case No. 9-20-cv-82214-RLR (served December 16, 2020) and Bird v. Boehringer Ingelheim Pharmaceuticals, et al., MDL No. 20-MD-2924, Case No. 9-20-cv-80837-RLR (served December 30, 2020). We have informed counsel for the plaintiffs that we did not sell an over the counter ranitidine product and sold a generic prescription ranitidine product for a limited two-month period of time, from July 2019 to September 2019. Our product was voluntarily recalled in January 2020. Each of the plaintiffs in the five pending cases alleges a cancer diagnosis prior to the time that ANI sold ranitidine, and we have informally sought dismissal from these cases on that basis. ANI was voluntarily dismissed from the Cooper, Lineberry and Lovette actions on November 20, 2020. ANI was voluntarily dismissed from the Bird action on March 15, 2021 and from the Hightower action on March 29, 2021. After ANI had been voluntarily dismissed from all complaints served on it in the MDL, the district court dismissed all claims against the generic manufacturer defendants with prejudice on preemption grounds by opinion dated July 8, 2021. We dispute any liability in these MDL matters. ​ Other Industry Related Matters On or about September 20, 2017, the Company and certain of its employees were served with search warrants and/or grand jury subpoenas to produce documents and possibly testify relating to a federal investigation of the generic pharmaceutical industry. We have been cooperating and intend to continue cooperating with the investigation. However, no assurance can be given as to the timing or outcome of the investigation.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	9 Months Ended

FAIR VALUE DISCLOSURES
FAIR VALUE DISCLOSURES	12. FAIR VALUE DISCLOSURES Fair value is the price that would be received from the sale of an asset or paid to transfer a liability assuming an orderly transaction in the most advantageous market at the measurement date. U.S. GAAP establishes a hierarchical disclosure framework that prioritizes and ranks the level of observability of inputs used in measuring fair value. The inputs used in measuring the fair value of cash and cash equivalents are considered to be Level 1 in accordance with the three-tier fair value hierarchy. The fair market values are based on period-end statements supplied by the various banks and brokers that held the majority of our funds. The fair value of short-term financial instruments (primarily accounts receivable, prepaid expenses, accounts payable, accrued expenses, and other current liabilities) approximate their carrying values because of their short-term nature. The Term Loan, DDTL, and Revolver bear an interest rate that fluctuates with the changes in LIBOR and, because the variable interest rates approximate market borrowing rates available to us, we believe the carrying values of these borrowings approximated their fair values at September 30, 2021. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Our contingent value rights (“CVRs”), which were granted coincident with our merger with BioSante and expire in June 2023, are considered contingent consideration and are classified as liabilities. As such, the CVRs were recorded as purchase consideration at their estimated fair value, using level 3 inputs, and are marked to market each reporting period until settlement. The fair value of CVRs is estimated using the present value of our projection of the expected payments pursuant to the terms of the CVR agreement, which is the primary unobservable input. If our projection or expected payments were to increase substantially, the value of the CVRs could increase as a result. The present value of the liability was calculated using a discount rate of 15%. We determined that the fair value of the CVRs was immaterial as of September 30, 2021 and December 31, 2020. We also determined that the changes in such fair value were immaterial in the three and nine months ended September 30, 2021 and 2020. The fair value of our interest rate swap is estimated based on the present value of projected future cash flows using the LIBOR forward rate curve. The model used to value the interest rate swap includes inputs of readily observable market data, a Level 2 input. As described in detail in Note 5, the fair value of the interest rate swap was a $7.9 million liability at September 30, 2021. The following table presents our financial assets and liabilities accounted for at fair value on a recurring basis as of September 30, 2021 and December 31, 2020, by level within the fair value hierarchy: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ Fair Value at ​ ​ ​ ​ ​ ​ ​ ​ ​ Description ​ September 30, 2021 ​ Level 1 ​ Level 2 ​ Level 3 Liabilities ​ ​ ​ ​ Interest rate swaps ​ $ 7,926 ​ $ — ​ $ 7,926 ​ $ — CVRs ​ $ — ​ $ — ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value at ​ ​ ​ ​ ​ ​ Description ​ December 31, 2020 ​ Level 1 ​ Level 2 ​ Level 3 Liabilities ​ ​ ​ ​ Interest rate swaps ​ $ 14,109 ​ $ — ​ $ 14,109 ​ $ — CVRs ​ $ — ​ $ — ​ $ — ​ $ — ​ Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis We do not have any financial assets and liabilities that are measured at fair value on a non-recurring basis. Non-Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis We do not have any non-financial assets and liabilities that are measured at fair value on a recurring basis. Non-Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis We measure our long-lived assets, including property, plant, and equipment, ROU assets, intangible assets, and goodwill, at fair value on a non-recurring basis. These assets are recognized at fair value when they are deemed to be other-than-temporarily impaired. No such fair value impairment was recognized in the three and nine months ended September 30, 2021 and 2020. Acquired Non-Financial Assets Measured at Fair Value In April 2021, we acquired three NDAs and an ANDA and certain related inventories from Sandoz, Inc. for total consideration of $20.7 million. We also incurred and paid $0.4 million in transaction costs directly related to the acquisition. The acquisition was funded via borrowings under our Revolver. We accounted for this transaction as an asset acquisition and capitalized the transaction costs directly related to the acquisition. We recognized $11.4 million as acquired intangible assets and $9.7 million of inventory at fair value, including $0.6 million of API, $1.0 million of sample inventory, and $8.1 million in finished goods inventory. In order to determine the fair value of the intangible assets, we used the present value of the estimated cash flows related to the product rights using a discount rate of 10% , which are level 3 unobservable inputs. In July 2020, we acquired an ANDA and certain related inventories from a private company for total consideration of $4.3 million. We also incurred and paid $0.1 million in transaction costs directly related to the acquisition. We accounted for this transaction as an asset acquisition and capitalized the transaction costs directly related to the acquisition. We recognized $3.0 million as an acquired ANDA intangible asset and $1.4 million in inventory at fair value. The fair value of the inventory was determined based on the estimated selling price to be generated from the finished goods, less costs to sell, including a reasonable margin, which are level 3 unobservable inputs. The ANDA is being amortized in full over its useful life of seven years and will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable. No such triggering events were identified during the period from the date of acquisition to June 30, 2021 and therefore no impairment loss was recognized for the nine months ended September 30, 2021. In January 2020, we completed the acquisition of the U.S. portfolio of 23 generic products and API and finished goods related to certain of those products from Amerigen Pharmaceuticals, Ltd. (“Amerigen”) for a purchase consideration of $56.8 million and up to $25.0 million in contingent payments over the next four years . Payments were made using cash on hand and through borrowings of $15.0 million under our Revolver. We also incurred and paid $0.7 million in transaction costs directly related to the acquisition. We accounted for the transaction as an asset acquisition and capitalized the transactions costs directly related to the acquisition. We recognized $38.5 million as acquired ANDA intangible assets and $6.7 million as acquired marketing and distribution rights related to the licensed products, which are being amortized over their useful lives of seven years . We also recognized $3.8 million of the purchase price as research and development expense because certain of the generic products had significant remaining work required in order to be commercialized and the products did not have an alternative future use. The payment was allocated to the two asset categories and in-process research and development based on relative fair value, which was determined using Level 3 unobservable inputs. To determine the fair value of the acquired intangible assets and in-process research and development, we used the present value of the estimated cash flows related to the products, using a discount rate of 8%. We also recognized $8.4 million in inventory at fair value, including $1.7 million of API and $6.7 million of finished goods. The fair value of the inventory was determined based on the estimated selling price to be generated from the finished goods, less costs to sell, including a reasonable margin, which are level 3 unobservable inputs. Contingent liabilities will be accrued when they are both estimable and probable. The intangible assets will be tested for impairment when events or circumstances indicate that the carrying value of the asset may not be recoverable. No such triggering events were identified during the period from the date of acquisition to September 30, 2021 and therefore no impairment loss was recognized for the nine months ended September 30, 2021.

PURIFIED CORTROPHIN GEL PRE-LAUNCH CHARGES
PURIFIED CORTROPHIN GEL PRE-LAUNCH CHARGES	13. In January 2016, we acquired the right, title and interest in the NDAs for Cortrophin Gel and Cortrophin-Zinc. Subsequently, we have assembled a Cortrophin Gel re-commercialization team of scientists, executed a long-term supply agreement with a supplier of pig pituitary glands, our primary raw material for corticotrophin API, executed a long-term supply agreement with an API manufacturer, with whom we have advanced the manufacture of corticotropin API via manufacture of commercial-scale batches, and executed a long-term commercial supply agreement with a current good manufacturing practice (“cGMP”) aseptic fill contract manufacturer. Prior to the third quarter 2019, all purchases of material, including pig pituitary glands and API, related to the re-commercialization efforts were consumed in research and development activities and recognized as research and development expense in the period in which they were incurred. In the third quarter of 2019, we began purchasing materials that are intended to be used commercially in anticipation of FDA approval of Cortrophin Gel and the resultant product launch. The FDA granted approval of the sNDA of this product on October 29, 2021. Prior to FDA approval, under U.S. GAAP, we were prohibited from capitalizing these pre-launch purchases of materials as inventory, and accordingly, they were charged to expense in the period in which they were incurred. Subsequent to approval, these purchases will be recorded as inventory at net realizable value. During the three and nine months ended September 30, 2021, we incurred $0.2 million and $0.8 million, respectively, of charges for the purchase of materials. During the three and nine months ended September 30, 2020, we incurred $0.1 million and $8.3 million, respectively in charges for the purchase of materials. We also incurred other charges directly related to the Cortrophin pre-launch commercialization efforts, including, but not limited to, sales and marketing and consulting expenses. During the three and nine months ended September 30, 2021, we incurred $2.1 million and $4.7 million, respectively, of these charges, which are included on the unaudited interim condensed consolidated statements of operations as a selling, general, and administrative expense. There were no comparable expenses in 2020.

BUSINESS, PRESENTATION, AND RECENT ACCOUNTING PRONOUNCEMENTS
Organization and Business	Overview ANI Pharmaceuticals, Inc. and its consolidated subsidiaries, ANIP Acquisition Company and ANI Pharmaceuticals Canada Inc. (together, “ANI,” the “Company,” “we,” “us,” or “our”), is an integrated specialty pharmaceutical company focused on delivering value to our customers by developing, manufacturing, and marketing high quality branded and generic prescription pharmaceuticals, including for diseases with high unmet medical need. We focus on niche and high barrier to entry opportunities, including controlled substances, oncology products (anti-cancer), hormones and steroids, and complex formulations. Our three pharmaceutical manufacturing facilities, of which two are located in Baudette, Minnesota and one is located in Oakville, Ontario, are together capable of producing oral solid dose products, as well as semi-solids, liquids and topicals, controlled substances, and potent products that must be manufactured in a fully-contained environment.
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In our opinion, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly our financial position, results of operations, comprehensive income, and cash flows. The consolidated balance sheet at December 31, 2020 has been derived from audited financial statements as of that date. The unaudited interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the U.S. Securities and Exchange Commission (the “SEC”). We believe that the disclosures provided herein are adequate to make the information presented not misleading when these unaudited interim condensed consolidated financial statements are read in conjunction with the audited financial statements and notes previously distributed in our Annual Report on Form 10-K for the year ended December 31, 2020.
Principles of Consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of ANI Pharmaceuticals, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.
Foreign Currency	Foreign Currency We have a subsidiary located in Canada. The subsidiary conducts its transactions in U.S. dollars and Canadian dollars, but its functional currency is the U.S. dollar. The results of any non-U.S. dollar transactions are remeasured in U.S. dollars at the applicable exchange rates during the period and resulting foreign currency transaction gains and losses are included in the determination of net income. Our gain or loss on transactions denominated in foreign currencies was immaterial for the three and nine months ended September 30, 2021 and 2020. Unless otherwise noted, all references to “$” or “dollar” refer to the U.S. dollar.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us 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 amount of revenues and expenses during the reporting period. In the accompanying unaudited interim condensed consolidated financial statements, estimates are used for, but not limited to, stock-based compensation, revenue recognition, allowance for credit losses, variable consideration determined based on accruals for chargebacks, administrative fees and rebates, government rebates, returns and other allowances, allowance for inventory obsolescence, valuation of financial instruments and intangible assets, accruals for contingent liabilities, fair value of long-lived assets, income tax provision or benefit, deferred taxes and valuation allowance, determination of right-of-use assets and lease liabilities, purchase price allocations, and the depreciable lives of long-lived assets. Because of the uncertainties inherent in such estimates, actual results may differ from those estimates. Management periodically evaluates estimates used in the preparation of the financial statements for reasonableness. We are subject to risks and uncertainties as a result of the novel coronavirus (“COVID-19”) pandemic. We are unable to predict the impact that the COVID-19 pandemic will continue to have on our future business, financial condition, and results of operations due to numerous uncertainties. These uncertainties include the occurrence of recurring outbreaks and their severity and the duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact and the direct and indirect economic effects of the pandemic and containment measures, among others. We remain unable to predict the future impact on our estimates and assumptions. There was no material impact to these estimates or assumptions in our consolidated financial statements as of and for the three and nine months ended September 30, 2021 and 2020. Actual results could differ from those estimates, which may change our estimates in future periods. We continue to closely monitor the impact of the COVID-19 pandemic on our business.
Geographic Information	Geographic Information Based on the distinct nature of our operations, our internal management structure, and the financial information that is evaluated regularly by our Chief Operating Decision Maker, we determined that we operate in one reportable segment. Our operations are located in the United States and Canada. The majority of the assets of the Company are located in the United States. The following table depicts the Company’s revenue by geographic operations during the following periods: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ Location of Operations 2021 2020 2021 2020 United States ​ $ 51,100 ​ $ 52,094 ​ $ 152,007 ​ $ 146,602 ​ Canada ​ 961 ​ 885 ​ 3,200 ​ 4,621 ​ Total Revenue ​ $ 52,061 ​ $ 52,979 ​ $ 155,207 ​ $ 151,223 ​ ​ The following table depicts the Company’s property and equipment, net according to geographic location as of: ​ ​ ​ ​ ​ ​ ​ ​ (in thousands) ​ September 30, 2021 ​ December 31, 2020 United States ​ $ 25,512 ​ $ 26,960 Canada ​ 14,014 ​ 14,309 Total property and equipment, net ​ $ 39,526 ​ $ 41,269
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted We have evaluated all issued and unadopted Accounting Standards Updates and believe the adoption of these standards will not have a material impact on our condensed consolidated statements of operations, comprehensive income, balance sheets, or cash flows. Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued guidance simplifying the accounting for certain financial instruments with characteristics of liabilities and equity, including certain convertible instruments and contracts on an entity’s own equity. The new standard removes the separation models required for convertible debt with cash conversion features and convertible instruments with beneficial conversion features. It also removes certain settlement conditions that are currently required for equity contracts to qualify for the derivative scope exception and simplifies the diluted earnings per share calculation for convertible instruments. We early adopted this guidance as of January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements but will impact how we account for newly issued convertible instruments in future periods. ​ In November 2019, the FASB issued guidance simplifying the accounting for income taxes by removing the following exceptions: 1) exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, 2) exception requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, 3) exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary, and 4) exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments also simplify accounting for income taxes by doing the following: 1) requiring that an entity recognize a franchise tax or similar tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, 2) requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction, 3) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements, 4) requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, and 5) making minor Codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. Most of the provisions of this guidance were to be adopted on a prospective basis. Items 2) and 3) of the “removal” provisions were to be adopted on either a full or modified retrospective basis and item 4) of the “simplifying” provisions was to be adopted on a full retrospective basis. The guidance was effective for reporting periods beginning after December 15, 2020, including interim periods within that fiscal year. We adopted this guidance as of January 1, 2021. The adoption of this guidance did not have a material impact on our consolidated financial statements.
