COVID-19 Pandemic

The Company is subject to risks and uncertainties as a result of the ongoing novel coronavirus pandemic, or COVID-19. The complete extent of the impact of the COVID-19 pandemic on the Company’s business is highly uncertain and difficult to predict, as the information is constantly evolving. The Company considered the impact of COVID-19 on the assumptions and estimates used to determine the results reported and asset valuations as of June 30, 2021.

AMPHASTAR PHARMACEUTICALS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

All of the Company’s production facilities continued to operate during the quarter as they had prior to the COVID-19 pandemic with very little change, other than for enhanced safety measures intended to prevent the spread of the virus.

It is not possible at this time to estimate the complete impact that COVID-19 could have on the Company’s business, including its customers and suppliers, as the impact will depend on future developments, which are highly uncertain and cannot be predicted. The Company will continue to monitor the impact of COVID-19 on all aspects of its business.

Use of Estimates

The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The principal accounting estimates include: determination of allowances for credit losses, allowance for discounts, provision for chargebacks and rebates, provision for product returns, adjustment of inventory to its net realizable values, impairment of long-lived and intangible assets and goodwill, workers’ compensation liabilities, litigation reserves, stock price volatilities for share-based compensation expense, valuation allowances for deferred tax assets, and liabilities for uncertain income tax positions.

Foreign Currency

The functional currency of the Company, its domestic subsidiaries, its Chinese subsidiary, ANP, and its U.K. subsidiary, AUK, is the US Dollar. ANP maintains its books of record in Chinese yuan. These books are remeasured into the functional currency of USD using current or historical exchange rates. The resulting currency remeasurement adjustments and other transactional foreign currency exchange gains and losses are reflected in the Company’s condensed consolidated statements of operations.

The Company’s French subsidiary, AFP, maintains its book of record in euros. ANP’s subsidiaries maintain their books of record in Chinese yuan. AUK’s subsidiary, IMS UK, maintains its book of record in British pounds. These local currencies have been determined to be the subsidiaries’ respective functional currencies. These books of record are translated into USD using average exchange rates during the period. Assets and liabilities are translated at the rate of exchange prevailing on the balance sheet date. Equity is translated at the prevailing rate of exchange at the date of the equity transactions. Translation adjustments are reflected in stockholders’ equity and are included as a component of other accumulated comprehensive income (loss). The unrealized gains or losses of intercompany foreign currency transactions that are of a long-term investment nature are reported in other accumulated comprehensive income (loss).

The unrealized gains or losses on intercompany foreign currency transactions that are of a long-term investment nature were a $0.4 million gain and a $1.0 million loss for the three and six months ended June 30, 2021, respectively. For the three months ended June 30, 2020, the unrealized gains or losses on intercompany foreign currency transactions that are of a long-term investment nature were a $0.7 million gain and an immaterial loss for the six months ended June 30, 2020.

Comprehensive Income (Loss)

For the three and six months ended June 30, 2021 and 2020, the Company included its foreign currency translation gain or loss as part of its comprehensive income (loss). There was no material income tax expense (benefit) allocated to other comprehensive income (loss) for the three and six months ended June 30, 2021 and 2020.

Advertising Expense

Advertising expenses, primarily associated with Primatene Mist^®, are recorded as they are incurred, except for expenses related to the development of a major commercial or media campaign, which are expensed in the period in which the commercial or campaign is first presented, and are reflected as a component of selling, distribution and marketing in the Company’s condensed consolidated statement of operations. For the three and six months ended June 30, 2021,

-8-

AMPHASTAR PHARMACEUTICALS, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

advertising expenses were $1.9 million and $4.1 million, respectively. For the three and six months ended June 30, 2020, advertising expenses were $1.4 million and $2.4 million, respectively.

Financial Instruments

The carrying amounts of cash and cash equivalents, short-term investments, restricted cash and short-term investments, accounts receivable, accounts payable, accrued expenses, and short-term borrowings approximate fair value due to the short maturity of these items. The majority of the Company’s long-term obligations consist of variable rate debt, and their carrying value approximates fair value as the stated borrowing rates are comparable to rates currently offered to the Company for instruments with similar maturities. The Company at times enters into fixed interest rate swap contracts to exchange the variable interest rates for fixed interest rates without the exchange of the underlying notional debt amounts. Such interest rate swap contracts are recorded at their fair values.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash, money market accounts, certificates of deposit and highly liquid investments purchased with original maturities of three months or less.

Short-Term Investments

Short-term investments as of June 30, 2021 and December 31, 2020 consisted of certificates of deposit and investment grade debt securities with original expiration dates within 12 months.

Restricted Cash

Restricted cash is generally collateral required for the Company to guarantee certain vendor payments in France. In May 2021, the Company posted an $18.9 million bond in connection with the Aventis litigation (see note 19). As of June 30, 2021 and December 31, 2020, the restricted cash balances were $19.2 million and $1.9 million, respectively.

Restricted Short-Term Investments

Restricted short-term investments consist of certificates of deposit that are collateral for standby letters of credit to qualify for workers’ compensation self-insurance. The certificates of deposit have original maturities greater than three months but less than one year. As of June 30, 2021 and December 31, 2020, the balance of restricted short-term investments was $2.2 million.

Deferred Income Taxes

The Company utilizes the liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statements and the tax basis of assets and liabilities using enacted tax rates. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the three months ended June 30, 2021 that are of significance or potential significance to the Company as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K filed with the SEC on March 15, 2021.

Note 3. ANP Restructuring

In July 2018, the Company’s Chinese subsidiary, ANP, completed a private placement of its common equity interest to accredited investors and received approximately $56.3 million of cash proceeds. The Company retained approximately 58% of the equity interest in ANP following the private placement and continues to consolidate the financial results of ANP with the Company’s results of operations. ANP’s net income after July 2, 2018, was attributed to the Company in accordance with the Company’s equity interest of approximately 58% in ANP.

In May 2021, the board of directors approved a plan for the restructuring of the equity ownership of ANP, whereby the Company purchased an additional ownership interest in ANP from certain equity holders of ANP, or the Sellers, and split-off certain subsidiaries of ANP.

Under the terms of the restructuring plan, the Company entered into a Share Purchase Agreement, or SPA, with certain of the Sellers to acquire an approximately 18% additional ownership interest in ANP for approximately $29.4 million in cash. The Company also entered into a Share Repurchase Agreement, or SRA, with certain of the Sellers, whereby the Company will contribute 80% of its ownership interest in Hanxin and its existing subsidiaries, Baixin and Letop, to the Sellers in exchange for approximately 10% additional ownership interest in ANP. The restructuring plan was subject to regulatory approval in China, which was not completed prior to June 30, 2021, and the assets of Hanxin and its subsidiaries are reflected as held and used in the condensed consolidated financial statements as of June 30, 2021.

Upon completion of the restructuring, the Company owned approximately 86% of ANP, and ANP owned approximately 20% of Hanxin. The restructuring plan was completed in July 2021, subsequent to the end of the second quarter.

Certain of the Sellers are the Company’s executive officers, directors and other related parties. The Sellers who participated in the SPA included executives of the Company William J. Peters, Rong Zhou, and Jacob Liawatidewi; directors of the Company Howard Lee and Richard Koo; relatives of Dr. Jack Zhang and Dr. Mary Luo, Henry Zhang, Qingqing Chen, Chongqing Zhang, Lu Zhang, and James Luo, or entities related to such persons. Neither Dr. Mary Luo, Dr. Jack Zhang nor affiliated entities participated in the SPA.

The Sellers who participated in the SRA included Dr. Mary Luo and Dr. Jack Zhang through an affiliated party, and their family members Henry Zhang, Qingqing Chen, Chongqing Zhang, Bill Zhang, and Lu Zhang.

During the second quarter of 2021, in connection with the restructuring, the Company terminated the 2018 ANP Equity Incentive Plan. (See note 16)

Note 4. Revenue Recognition

In accordance with Accounting Standard Codification, or ASC, 606 Revenue from Contracts with Customers, revenue is recognized at the time that the Company’s customers obtain control of the promised goods.

Generally, revenue is recognized at the time of product delivery to the Company’s customers. In some cases, revenue is recognized at the time of shipment when stipulated by the terms of the sale agreements.

The consideration the Company receives in exchange for its goods or services is only recognized when it is probable that a significant reversal will not occur. The consideration to which the Company expects to be entitled includes a stated list price, less various forms of variable consideration. The Company makes significant estimates for related variable consideration at the point of sale, including chargebacks, rebates, product returns, other discounts and allowances.

The Company’s payment terms vary by types and locations of customers and the products or services offered. Payment terms differ by jurisdiction and customers, but payment is generally required in a term ranging from 30 to 75 days from

-10-

(Unaudited)

date of shipment or satisfaction of the performance obligation. For certain products or services and certain customer types, we may require payment before products are delivered or services are rendered to customers.

Provisions for estimated chargebacks, rebates, discounts, product returns and credit losses are made at the time of sale and are analyzed and adjusted, if necessary, at each balance sheet date.

Revenues derived from contract manufacturing services are recognized when third-party products are shipped to customers, and after the customer has accepted test samples of the products to be shipped.

The Company’s accounting policy is to review each agreement involving contract development and manufacturing services to determine if there are multiple revenue-generating activities that constitute more than one unit of accounting. Revenues are recognized for each unit of accounting based on revenue recognition criteria relevant to that unit. The Company does not have any revenue arrangements with multiple performance obligations.

Provision for Chargebacks and Rebates

The provision for chargebacks and rebates is a significant estimate used in the recognition of revenue. Wholesaler chargebacks relate to sales terms under which the Company agrees to reimburse wholesalers for differences between the gross sales prices at which the Company sells its products to wholesalers and the actual prices of such products that wholesalers resell under the Company’s various contractual arrangements with third parties such as hospitals and group purchasing organizations in the United States. Rebates include primarily amounts paid to retailers, payers, and providers in the United States, including those paid to state Medicaid programs, and are based on contractual arrangements or statutory requirements. The Company estimates chargebacks and rebates using the expected value method at the time of sale to wholesalers based on wholesaler inventory stocking levels, historic chargeback and rebate rates, and current contract pricing.

The provision for chargebacks and rebates is reflected as a component of net revenues. The following table is an analysis of the chargeback and rebate provision:


	Six Months Ended
	June 30,
	2021		2020

	(in thousands)
Beginning balance	$	20,380	$	21,644
Provision for chargebacks and rebates		97,973		69,424
Credits and payments issued to third parties		(99,400)		(72,625)
Ending balance	$	18,953	$	18,443

Changes in the chargeback provision from period to period are primarily dependent on the Company’s sales to its wholesalers, the level of inventory held by wholesalers, and the wholesalers’ customer mix. Changes in the rebate provision from period to period are primarily dependent on retailer’s and other indirect customers’ purchases. The approach that the Company uses to estimate chargebacks has been consistently applied for all periods presented. Variations in estimates have been historically small. The Company continually monitors the provision for chargebacks and rebates and makes adjustments when it believes that the actual chargebacks and rebates may differ from the estimates. The settlement of chargebacks and rebates generally occurs within 30 days to 60 days after the sale to wholesalers. Accounts receivable and/or accounts payable and accrued liabilities are reduced and/or increased by the chargebacks and rebate amounts depending on whether the Company has the right to offset with the customer. Of the provision for chargebacks and rebates as of June 30, 2021 and December 31, 2020, $15.1 million and $16.4 million were included in accounts receivable, net, on the condensed consolidated balance sheets, respectively. The remaining provision as of June 30, 2021 and December 31, 2020 of $3.9 million and $4.0 million, respectively, were included in accounts payable and accrued liabilities.

Accrual for Product Returns

The Company offers most customers the right to return qualified excess or expired inventory for partial credit; however, API product sales are generally non-returnable. The Company’s product returns primarily consist of the returns of expired products from sales made in prior periods. Returned products cannot be resold. At the time product revenue is recognized, the Company records an accrual for product returns estimated using the expected value method. The accrual is based, in part, upon the historical relationship of product returns to sales and customer contract terms. The Company also assesses other factors that could affect product returns including market conditions, product obsolescence, and the introduction of new competition. Although these factors do not normally give the Company’s customers the right to return products outside of the regular return policy, the Company realizes that such factors could ultimately lead to increased returns. The Company analyzes these situations on a case-by-case basis and makes adjustments to the product return reserve as appropriate.

The provision for product returns is reflected as a component of net revenues. The following table is an analysis of the product return liability:


	Six Months Ended
	June 30,
	2021		2020

	(in thousands)
Beginning balance	$	14,204	$	10,339
Provision for product returns		7,770		6,208
Credits issued to third parties		(4,433)		(3,989)
Ending balance	$	17,541	$	12,558

Of the provision for product returns as of June 30, 2021 and December 31, 2020, $14.1 million and $10.2 million, were included in accounts payable and accrued liabilities on the condensed consolidated balance sheets, respectively. The remaining provision as of June 30, 2021 and December 31, 2020, of $3.4 million and $4.0 million, were included in other long-term liabilities, respectively. For the six months ended June 30, 2021 and 2020, the Company’s aggregate product return rate was 1.6% and 1.3% of qualified sales, respectively.

Note 5. Income (loss) per Share Attributable to Amphastar Pharmaceuticals, Inc. Stockholders

Basic net income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. stockholders is calculated based upon the weighted-average number of shares outstanding during the period. Diluted net income (loss) per share attributable to Amphastar Pharmaceuticals, Inc. stockholders gives effect to all potential dilutive shares outstanding during the period, such as stock options, non-vested restricted stock units and shares issuable under the Company’s Employee Stock Purchase Plan, or ESPP and the reallocation of net income (loss) attributable to non-controlling interest from the assumed dilutive effect of stock options issued under the 2018 ANP Equity Incentive Plan, or the 2018 Plan.

For the three and six months ended June 30, 2021, options to purchase 2,056,803 shares of stock, with a weighted-average exercise price of $20.75 per share, and the reallocation of net income attributable to non-controlling interests were excluded from the computation of diluted net income per share attributable to Amphastar Pharmaceuticals, Inc. stockholders because the effect would be anti-dilutive.

As the Company reported a net loss for the three months ended June 30, 2020, the diluted net loss per share attributable to Amphastar Pharmaceuticals, Inc. stockholders, as reported, equals the basic net loss per share attributable to Amphastar Pharmaceuticals, Inc. stockholders since the effect of the assumed exercise of stock options, vesting of non-vested RSUs, and issuance of common shares under the Company’s ESPP are anti-dilutive. Total stock options, non-vested RSUs, and shares issuable under the Company’s ESPP excluded from the three months ended June 30, 2020 net loss per share were 8,887,036 stock options, 1,176,479 non-vested RSUs, and 60,386 shares issuable under the ESPP.

and market its products, it could have a materially adverse effect on the Company’s business, financial condition, and results of operations.

Note 8. Fair Value Measurements

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability at the measurement date (an exit price). These standards also establish a hierarchy that prioritizes observable and unobservable inputs used in measuring fair value of an asset or liability, as described below:

●

Level 1 – Inputs to measure fair value are based on quoted prices (unadjusted) in active markets on identical assets or liabilities;

●

Level 2 – Inputs to measure fair value are based on the following: a) quoted prices in active markets on similar assets or liabilities, b) quoted prices for identical or similar instruments in inactive markets, or c) observable (other than quoted prices) or collaborated observable market data used in a pricing model from which the fair value is derived; and

●

Level 3 – Inputs to measure fair value are unobservable and the assets or liabilities have little, if any, market activity; these inputs reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities based on best information available in the circumstances.

As of June 30, 2021, cash equivalents include money market accounts. Short-term investments consist of certificates of deposit as well as investment-grade municipal bonds with original expiration dates within 12 months. The certificates of deposit are carried at amortized cost in the Company’s condensed consolidated balance sheet, which approximates their fair value determined based on Level 2 inputs. The corporate and municipal bonds are classified as held-to-maturity and are carried at amortized cost net of allowance for credit losses, which approximates their fair value determined based on Level 2 inputs. The restrictions on restricted cash and short-term investments have a negligible effect on the fair value of these financial assets.

The fair value of the Company’s financial assets and liabilities measured on a recurring basis as of June 30, 2021 and December 31, 2020, are as follows:

The Company does not hold any Level 3 instruments that are measured at fair value on a recurring basis.

Nonfinancial assets and liabilities are not measured at fair value on a recurring basis but are subject to fair value adjustments in certain circumstances. These items primarily include long-lived assets, goodwill, and intangible assets for which the fair value of assets is determined as part of the related impairment test. As of June 30, 2021 and December 31, 2020, there were no significant adjustments to fair value for nonfinancial assets or liabilities.

Note 9. Investments

Total investments as of December 31, 2020	$	3,857	$	—	$	(2)	$	3,855

At each reporting period, the Company evaluates securities for impairment when the fair value of the investment is less than its amortized cost. The Company evaluated the underlying credit quality and credit ratings of the issuers, noting neither a significant deterioration since purchase nor any other factors that would indicate a material credit loss.

The Company measures expected credit losses on held-to-maturity investments on a collective basis. All the Company’s held-to-maturity investments were considered to be one pool. The estimate for credit losses considers historical loss information that is adjusted for current conditions and reasonable and supportable forecasts. Expected credit losses on held-to-maturity investments were not material to the condensed consolidated financial statements.

Primatene^® Trademark

In January 2009, the Company acquired the exclusive rights to the trademark, domain name, website and domestic marketing, distribution and selling rights related to Primatene Mist^®, an over-the-counter bronchodilator product, recorded at the allocated fair value of $29.2 million, which is its carrying value as of June 30, 2021.

The trademark was determined to have an indefinite life. In determining its indefinite life, the Company considered the following: the expected use of the intangible; the longevity of the brand; the legal, regulatory and contractual provisions that affect their maximum useful life; the Company’s ability to renew or extend the asset’s legal or contractual life without substantial costs; effects of the regulatory environment; expected changes in distribution channels; maintenance expenditures required to obtain the expected future cash flows from the asset; and considerations for obsolescence, demand, competition and other economic factors.

Note 15. Income Taxes

The following table sets forth the Company’s income tax provision (benefit) for the periods indicated:


	Three Months Ended						Six Months Ended

Income tax provision (benefit) as a percentage of income (loss) before income taxes		39.4	%		5.0	%		34.9	%		51.3	%

The change in the Company’s effective tax rate for the three and six months ended June 30, 2021, was primarily due to differences in pre-tax income (loss) positions and timing of discrete tax items.

Valuation Allowance

In assessing the need for a valuation allowance, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will be realized. Ultimately, realization depends on the existence of future taxable income. Management considers sources of taxable income such as income in prior carryback periods, future reversal of existing deferred taxable temporary differences, tax-planning strategies, and projected future taxable income.

The Company continues to record a full valuation allowance on the net deferred income tax assets of its subsidiaries AFP and Hanxin and will continue to do so until the subsidiaries generate sufficient taxable income to realize their respective deferred income tax assets.

For purposes of computing its annual effective tax rate, the Company did not benefit from its losses in the states where it files separately. This increased the Company’s income tax expense by $0.1 million and $0.2 million for the three and six months ended June 30, 2021, respectively. The change in the Company’s income tax benefit was immaterial for the three months ended June 30, 2020 and the increase in tax expense was $0.2 million for the six months ended June 30, 2020.

Note 16. Stockholders' Equity

Share Buyback Program

Pursuant to the Company’s existing share buyback program, the Company purchased 298,727 and 503,425 shares of its common stock during the three and six months ended June 30, 2021, for total consideration of $5.5 million and $9.3 million, respectively. The Company purchased 329,391 and 976,106 shares of its common stock during the three and six months ended June 30, 2020, for total consideration of $5.8 million and $16.7 million, respectively.

In August 2021, the Company’s Board of Directors authorized an increase of $20.0 million to the Company’s share buyback program, which is expected to continue for an indefinite period of time. Since the inception of the program, the Company’s Board of Directors have authorized a total of $160.0 million to the Company’s share buyback program. The primary goal of the program is to offset dilution created by the Company’s equity compensation programs.

Purchases are made through open market and private block transactions pursuant to Rule 10b5-1 plans, privately negotiated transactions or other means as determined by the Company’s management and in accordance with the requirements of the SEC and applicable laws. The timing and actual number of treasury share purchases will depend on a variety of factors including price, corporate and regulatory requirements, and other conditions. These treasury share

Amended and Restated 2015 Equity Incentive Plan

As of June 30, 2021, the Company reserved an aggregate of 5,976,576 shares of common stock for future issuance under the Amended and Restated 2015 Equity Incentive Plan, or the 2015 Plan, including 1,187,386 shares, which were reserved in January 2021 pursuant to the evergreen provision in the 2015 Plan.

2014 Employee Stock Purchase Plan

As of June 30, 2021, the Company has issued 890,904 shares of common stock under the ESPP, and 1,109,096 shares of its common stock remains available for issuance under the ESPP.

In May 2021, the Company issued 83,354 shares at a weighted-average purchase price of $15.25 per share under the ESPP. For the three and six months ended June 30, 2021, the Company recorded ESPP expense of $0.2 million and $0.3 million, respectively. For the three and six months ended June 30, 2020, the Company recorded ESPP expense of $0.3 million and $0.4 million, respectively.

Share-Based Award Activity and Balances (excluding the ANP Equity Plan)

The Company accounts for share-based compensation payments in accordance with ASC 718, which requires measurement and recognition of compensation expense at fair value for all share-based payment awards made to employees and directors. Under these standards, the fair value of option awards and the option components of the Employee Stock Purchase Plan awards are estimated at the grant date using the Black-Scholes option-pricing model. The fair value of RSUs is estimated at the grant date using the Company’s common share price. The portion that is ultimately expected to vest is amortized and recognized in compensation expense on a straight-line basis over the requisite service period, generally from the grant date to the vesting date.

The weighted-averages for key assumptions used in determining the fair value of options granted during the three and six months ended June 30, 2021 and 2020, are as follows:


	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2021		2020		2021		2020

In April 2020, Jason Shandell resigned from his position as the Company’s President and General Counsel and as a member of the Company’s board of directors. In connection with his resignation, the Company and Mr. Shandell entered into a separation agreement. As part of the separation agreement, the Company agreed to accelerate 80% of his unvested stock options and extended the expiration date of certain vested stock option awards. As a result of this modification, the Company incurred share-based compensation expense of $0.7 million, which is included within general and administration expenses in the condensed consolidated statement of operations for the six months ended June 30, 2020.

As of June 30, 2021, there was $15.8 million of total unrecognized compensation cost, net of forfeitures, related to non-vested stock option based compensation arrangements granted under all plans. The cost is expected to be recognized over a weighted-average period of 2.7 years and will be adjusted for future changes in estimated forfeitures.

Restricted Stock Units

The Company grants restricted stock units, or RSUs, to certain employees and members of the Board of Directors with a vesting period of up to five years. The grantee receives 1 share of common stock at a specified future date for each RSU awarded. The RSUs may not be sold or otherwise transferred until certificates of common stock have been issued, recorded, and delivered to the participant. The RSUs do not have any voting or dividend rights prior to the issuance of certificates of the underlying common stock. The share-based expense associated with these grants was based on the Company’s common stock fair value at the time of grant and is amortized over the requisite service period, which generally is the vesting period using the straight-line method. During the three and six months ended June 30, 2021, the Company recorded total expenses of $2.1 million and $4.3 million, respectively, related to RSU awards granted. During the three and six months ended June 30, 2020, the Company recorded expenses of $3.6 million and $6.0 million, respectively, related to RSU awards granted.

As part of the separation agreement with Mr. Shandell, the Company agreed to accelerate the vesting of 80% of his RSU awards. As a result of this modification, the Company incurred share-based compensation expense of $1.6 million, which is included within general and administrative expenses in the condensed consolidated statement of operations for the six months ended June 30, 2020.

As of June 30, 2021, there was $16.8 million of total unrecognized compensation cost, net of forfeitures, related to non-vested RSU-based compensation arrangements granted under all plans. The cost is expected to be recognized over a weighted-average period of 2.7 years and will be adjusted for future changes in estimated forfeitures.

The 2018 ANP Equity Incentive Plan

In December 2018, ANP’s board of directors approved the 2018 ANP Equity Incentive Plan, or the 2018 Plan, which was set to expire in December 2023. The 2018 Plan permitted the grant of stock options and other equity awards in ANP shares to ANP employees.

During the second quarter of 2021, in connection with the ANP restructuring, the Company terminated the 2018 Plan.

At the time of the 2018 Plan termination, the number of stock options outstanding was 5,018,880. As part of the termination, ANP cash settled 4,091,080 stock options, of which, 1,944,771 stock options were vested and 2,146,309

stock options were unvested, for $0.8 million which approximated the fair value of these awards at the time of settlement. The cash settlement of these awards was recorded as a reduction in equity.

For the remaining 927,800 stock option awards that were outstanding under the 2018 Plan, of which 56,925 stock options were vested and 870,875 were unvested, the Company cancelled these awards and issued replacement awards under the 2015 Plan. The modified awards vest over periods ranging from 1 to 2 years and have a 10-year contractual term. The cancellation and replacement of the awards was accounted for as a modification in accordance with ASC 718.

As a result of the modification, the Company incurred $2.3 million of share-based compensation expense, of which $1.8 million was recorded within general and administrative expenses in the condensed consolidated statement of operations for the three and six months ended June 30, 2021, and the remaining $0.5 million which will be recognized over the vesting period of the modified awards.

Prior to the termination and modification of the 2018 Plan, during the three and six months ended June 30, 2020, the Company recorded expense of $0.2 million and $0.3 million related to stock options issued by ANP under the 2018 Plan, respectively.

Note 17. Employee Benefits

401(k) Plan

The Company has a defined contribution 401(k) plan, or the Plan, whereby eligible employees voluntarily contribute up to a defined percentage of their annual compensation. The Company matches contributions at a rate of 50% on the first 6% of employee contributions, and pays the administrative costs of the Plan. Total employer contributions for the three and six months ended June 30, 2021 were approximately $0.6 million and $1.1 million, respectively, compared to the prior year expense of $0.5 million and $1.0 million for the three and six months ended June 30, 2020, respectively.

Defined Benefit Pension Plan

The Company’s subsidiary, AFP, has an obligation associated with a defined-benefit plan for its eligible employees. This plan provides benefits to the employees from the date of retirement and is based on the employee’s length of time employed by the Company. The calculation is based on a statistical calculation combining a number of factors that include the employee’s age, length of service, and AFP employee turnover rate.

The liability under the plan is based on a discount rate of 0.3% as of June 30, 2021 and December 31, 2020. The liability is included in accrued liabilities in the accompanying condensed consolidated balance sheets. The plan is currently unfunded, and the benefit obligation under the plan was $3.0 million at June 30, 2021 and December 31, 2020. The

Company recorded an immaterial amount of expense under the plan for the three and six months ended June 30, 2021 and 2020.

Deferred Compensation Plan

In December 2019, the Company established a non-qualified deferred compensation plan. The deferred compensation plan allows certain eligible participants to defer a portion of their cash compensation and provides a matching contribution at the discretion of the Company. The plan obligations are payable upon retirement, termination of employment and/or certain other times in a lump-sum distribution or in installments, as elected by the participant in accordance with the plan. Participants can allocate their deferred compensation amongst various investment options with earnings accruing to the participant. The Company has established a Rabbi Trust to fund the plan obligations and to hold the plan assets. Eligible participants began contributing to the plan in January 2020. As of June 30, 2021, the plan assets and liabilities were valued at approximately $2.4 million and $2.5 million, respectively. As of December 31, 2020, the plan assets and liabilities were valued at approximately $1.6 million and $1.7 million, respectively.

Note 18. Commitments and Contingencies

Purchase Commitments

As of June 30, 2021, the Company has entered into commitments to purchase equipment and raw materials for an aggregate amount of approximately $55.7 million. The Company anticipates that most of these commitments with a remaining term in excess of one year will be fulfilled by 2022.

Note 19. Litigation

Amphastar Pharmaceuticals, Inc. v. Aventis Pharma, SA

In January 2009, the Company filed a qui tam complaint in the U.S. District Court for the Central District of California, alleging that Aventis Pharma S.A., or Aventis, through its acquisition of a patent through false and misleading statements to the U.S. Patent and Trademark Office, as well as through false and misleading statements to the FDA, overcharged the federal and state governments for its Lovenox^® product.

On May 11, 2017, the Company’s lawsuit against Aventis was dismissed for lack of jurisdiction. On July 14, 2017, Aventis filed an application with the District Court for entitlement to attorneys’ fees and expenses. On November 20, 2017, the District Court issued its order granting Aventis’ application for fees, and on November 13, 2020, the Court issued an Order (“November Order”) awarding Aventis $12.1 million in attorneys’ fees and $0.7 million in cost and expenses.

On May 3, 2021, the Court issued a further Order based upon supplemental application to the Court seeking fees, expenses, and interest for the period after, and not covered by, the November Order. The Court awarded Aventis an additional $4.4 million bringing the total awarded Aventis to $17.2 million.

The Company had previously accrued $12.8 million as of December 31, 2020, based upon the November Order. As a result of the most recent ruling, the Company recorded an additional charge of $4.4 million for the three months ended March 31, 2021, in other income (expenses), in the condensed consolidated statement of operations. This amount represented management’s best estimate of the probable loss at that time.

On June 30, 2021, the Company and Aventis entered into a settlement agreement to settle the attorney fees’ and expenses for $14.5 million. As a result of this settlement, the accrual amount was reduced by $2.7 million for the three months ended June 30, 2021, with a corresponding credit to other income (expense) in the consolidated statement of operations.

Regadenoson (0.4 mg/5 mL, 0.08 mg/mL) Patent Litigation

On February 25, 2020, Astellas US LLC, Astellas Pharma US, Inc., and Gilead Sciences, Inc. (collectively, “Astellas-Gilead”) filed a Complaint in the United States District Court for the District of Delaware against IMS for infringement of U.S. Patent Nos. 8,106,183 (the “‘183 patent”), RE47,301 (the “‘301 patent”), and 8,524,883 (the “‘883 patent”) (collectively, “Astellas-Gilead Patents”) with regard to IMS’s ANDA No. 214,252 for approval to manufacture and sell 0.4 mg/5 mL (0.08 mg/mL) intravenous solution of Regadenoson. On March 4, 2020, IMS filed its Answer and Counterclaims. On March 30, 2020, the Court issued an Order allowing the Company to join pending consolidated litigation with five other generic Regadenoson ANDA filers involving similar claims. Trial is currently scheduled for January 2022. The Company’s 30-month FDA stay expires August 10, 2022. Currently, this lawsuit does not expose the Company to any liabilities, as the product has not been launched. The Company intends to vigorously defend this patent lawsuit.

Ramirez v. Amphastar Pharmaceuticals, Inc.

On May 29, 2020, Priscilla Ramirez (“Ramirez”), a former employee filed a PAGA lawsuit for alleged violations of various California labor laws pertaining to wage and hour against the Company. On April 5, 2021, the parties reached a settlement for $1.0 million. On June 9, 2021, Ramirez submitted a motion to the Court to approve the settlement which is still subject to approval by the Court. The Company accrued the amount of $1.0 million for this litigation as of March 31, 2021.

Other Litigation

The Company is also subject to various other claims, arbitrations, and lawsuits from time to time arising in the ordinary course of business.

The Company records a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the opinion of management, the ultimate resolution of any such matters is not expected to have a material adverse effect on its financial position, results of operations, or cash flows; however, the results of litigation and claims are inherently unpredictable and the Company’s view of these matters may change in the future. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.

Note 20. Subsequent Events

ANP Restructuring

In July 2021, the Company completed the restructuring of ANP. As a result of the restructuring, the Company’s ownership interest in ANP was increased to approximately 86%, and the ownership interest in Hanxin and its subsidiaries was reduced to approximately 20%. (See note 3)

Credit Agreement with Capital One N.A. - Due August 2026

In August 2021, the Company entered into a $140.0 million credit agreement with Capital One N.A. acting as a lender and as agent for other lenders. Under the terms of the credit agreement, the Company will borrow $70.0 million in the form of a term loan. Proceeds from the loan will be used to pay down certain of the Company’s outstanding debt. The interest rate on the term loan will be based on a variable interest rate, plus an applicable margin rate determined based on the Company’s net leverage ratio as defined by the terms of the agreement. The loan matures in August 2026.

The loan requires principal payments of $1.8 million per year for the first two years, which increases to $3.5 million during the third and fourth year and to $3.9 million in the fifth year, with the remaining balance due at maturity. The loan is secured by substantially all of the Company’s assets, excluding assets of ANP.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion and analysis of the consolidated operating results, financial condition, liquidity and cash flows of our company as of and for the periods presented below. The following discussion and analysis should be read in conjunction with the “Condensed Consolidated Financial Statements” and the related notes thereto included in this Quarterly Report on Form 10-Q, or Quarterly Report. This discussion contains forward-looking statements that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Actual results could differ materially from those discussed in or implied by forward-looking statements. These risks, uncertainties, and other factors include, among others, those identified under the “Special Note About Forward-Looking Statements,” above and described in greater detail elsewhere in this Quarterly Report and in our Annual Report on Form 10-K for the year ended December 31, 2020, particularly in Item 1A. “Risk Factors”.

Overview

We are a bio-pharmaceutical company that focuses primarily on developing, manufacturing, marketing and selling technically challenging generic and proprietary injectable, inhalation, and intranasal products as well as insulin API products. We currently manufacture and sell over 20 products.

We are currently developing a portfolio of 12 generic abbreviated new drug applications, or ANDAs, three biosimilar insulin product candidates and four proprietary product candidates, which are in various stages of development and target a variety of indications. Five of the ANDAs and one NDA are currently on file with the FDA.

Our largest products by net revenues currently include Primatene Mist^®, glucagon, epinephrine, enoxaparin sodium injection, lidocaine jelly and sterile solution, and phytonadione. During the second quarter of 2020, we launched our epinephrine injection, USP 30mg/mL multiple dose vial product. In December 2020, the FDA granted approval of our glucagon for injection emergency kit, 1mg, which we launched in February 2021.

To complement our internal growth and expertise, we have made several strategic acquisitions of companies, products and technologies. These acquisitions collectively have strengthened our core injectable and inhalation product technology infrastructure by providing additional manufacturing, marketing, and research and development capabilities, including the ability to manufacture raw materials, API and other components for our products.

Included in these acquisitions are marketing authorizations for 33 products in the UK, Ireland, Australia, and New Zealand, representing 11 different injectable chemical entities. We are in the process of transferring the manufacturing of these products to our facilities in California, which will require approvals from the UK Medicines and Healthcare products Regulatory Agency before we can relaunch the products.

In July 2018, our Chinese subsidiary, ANP, completed a private placement of its common equity interest and received approximately $56.3 million of cash proceeds. We have retained approximately 58% of the equity interest in ANP following the private placement. ANP’s net income or loss after July 2, 2018, is attributed to us in accordance with our equity interest of approximately 58% in ANP.

In May 2021, the board of directors approved a plan for the restructuring of the equity ownership of ANP, whereby we would purchase additional ownership interest in ANP from certain equity holders of ANP (the “Sellers”), and spin-off certain subsidiaries of ANP. The Sellers include some of the Company’s executive officers, directors and other related parties who participated in the ANP Private Placement in 2018.

The ANP restructuring was completed in July 2021, we paid approximately $29.4 million in cash and contributed approximately 80% of Hanxin Pharmaceutical Technology Co., Ltd, or Hanxin, to the Sellers in exchange for additional ownership interest in ANP, such that we now own approximately 86% of ANP and ANP retained approximately 20% of

ownership in Hanxin. Hanxin’s wholly owned subsidiaries, Nanjing Baixin Trading Co., Ltd., and Nanjing Letop Biological Technology Co., Ltd., were included in the split-off of Hanxin.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the outbreak of a novel coronavirus, or COVID-19, as a pandemic, which continues to spread throughout the world, including locations where we operate, such as the United States, China and France. We have been actively monitoring the COVID-19 pandemic, including regarding the Delta variant, and its impact globally. Currently, our production facilities in all of our locations continue to operate as they had prior to the COVID-19 pandemic with few changes, other than for enhanced safety measures intended to prevent the spread of the virus.

As a result of the COVID-19 pandemic, during the first half of 2020, sales of Primatene Mist^® and certain hospital products increased, while sales of certain products frequently used in elective procedures, such as Cortrosyn^® and lidocaine products decreased. We saw these trends continue in late 2020 and early 2021 when COVID cases trended higher. During the second quarter of 2021, the sales of these products, frequently used in elective procedures returned to their normal level.

Some of our ongoing clinical trials experienced short-term interruptions in the recruitment of patients due to the COVID-19 pandemic, as hospitals prioritize their resources towards the COVID-19 pandemic and governments impose travel restrictions. Some clinical trials experienced increased expenses due to new protocols to protect participants from COVID-19. Additionally, certain suppliers had difficulties meeting their delivery commitments.

It is not possible at this time to estimate the complete impact that COVID-19 could have on our business, including our customers and suppliers, as the impact will depend on future developments, which are highly uncertain and cannot be predicted. Infections may resurge or become more widespread and the limitation on our ability to travel and timely sell and distribute our products, as well as any closures or supply disruptions, may be extended for longer periods of time, all of which would have a negative impact on our business, financial condition and operating results.

The COVID-19 pandemic has and will continue to adversely affect global economies and financial markets, potentially resulting in an economic downturn that could affect demand for our products and impact our operating results. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a result of the continued global economic impact of the pandemic. We cannot anticipate all of the ways in which health epidemics such as COVID-19 could adversely impact our business. See the “Risk Factors” section for further discussion of the possible impact of the COVID-19 pandemic on our business.

Business Segments

As of June 30, 2021, our performance is assessed and resources are allocated based on the following two reportable segments: (1) finished pharmaceutical products and (2) API products. The finished pharmaceutical products segment manufactures, markets and distributes Primatene Mist^®, glucagon, enoxaparin, naloxone, phytonadione, lidocaine, epinephrine, as well as various other critical and non-critical care drugs. The API segment manufactures and distributes RHI API and porcine insulin API for external customers and internal product development. Information reported herein is consistent with how it is reviewed and evaluated by our chief operating decision maker. Factors used to identify our segments include markets, customers and products.

We launched glucagon for injection emergency kit, 1mg in the first quarter of 2021. The increase in sales of Primatene Mist^® for the three months ended June 30, 2021, was primarily a result of the continued success of our nationwide digital, television and radio campaign, which will continue throughout 2021 as well as an expansion of our distribution channels throughout 2020 and 2021. The increase in sales of lidocaine and epinephrine was primarily due an increase in unit volumes, as a result of higher demand due to a market shortage. The decrease in sales of enoxaparin was primarily due to lower average selling price as a competitor re-entered the market. The decrease in sales of Naloxone was primarily due to lower average selling price as a result of a competitor entering the market. The decrease in sales of phytonadione was primarily due to lower unit volumes as a result of decreased market demand. The decrease in other finished pharmaceutical products was primarily due to lower unit volumes as a result of competitors returning to their normal distribution levels after being unable to supply market demands in 2020.

We anticipate that sales of naloxone and enoxaparin will continue to fluctuate in the future as a result of changing levels of competition.

-31-

Sales of API primarily depend on the timing of customer purchases. In May 2021, we amended the Supply Agreement with MannKind Corporation, or MannKind, whereby MannKind’s aggregate total commitment of RHI API under the Supply Agreement was modified and extended for an additional year through 2027, which timeframe would have previously lapsed after calendar year 2026. MannKind has agreed to pay us an amendment fee of $2.0 million. We received the first payment of the amendment fee of $1.0 million in June 2021 and recognized $0.5 million in net revenues during the three months ended June 30, 2021. The remaining $0.5 million was recorded as a contract liability in our condensed consolidated balance sheet as of June 30, 2021 and will be recognized ratably to net revenues over the remaining quarters in 2021. The remaining balance of $1.0 million of the amendment fee is due January 2022 and relates to the amendments to the 2022 supply level and will be recognized ratably to net revenues in 2022.

We anticipate that sales of API will continue to fluctuate and may decrease due to the inherent uncertainties related to sales to MannKind Corporation pursuant to our supply agreement with them. In addition, most of our API sales are denominated in euros, and the fluctuation in the value of euros versus the U.S. dollar has had, and will continue to have, an impact on API sales revenues in the near term.

A significant portion of our customer shipments in any period relate to orders received and shipped in the same period, generally resulting in low product backlog relative to total shipments at any time. We had no significant backlog as of June 30, 2021. Historically, our backlog has not been a meaningful indicator in any given period of our ability to achieve any particular level of overall revenue or financial performance.

Gross margins

The increase in sales of Primatene Mist^® and our epinephrine injection multiple dose vial, as well as the launch of glucagon for injection emergency kit during the first quarter of 2021, which are higher-margin products, helped increase our gross margins for the three months ended June 30, 2021. These increases in gross margins were partially offset by lower pricing and increased costs for enoxaparin, particularly the cost for heparin raw material, which is used as the starting material for enoxaparin.

The cost of heparin may increase further, putting downward pressure on our gross margins. However, we believe that this trend will be offset by sales of our higher-margin products, such as Primatene Mist^®, and epinephrine multi dose vials, which were launched over the past few years and by glucagon which was launched in 2021. Additionally, we have not seen significant supply disruptions due to the COVID-19 pandemic at this time, but we are continuing to monitor our supply chain for any potential problems.

General and administrative	$	14,565	$	15,924	$	(1,359)	(9)	%

The increase in selling, distribution, and marketing expenses was primarily due to marketing expenses related to Primatene Mist^®. The decrease in general and administrative expense was primarily due to cash compensation and share-based compensation expense relating to the separation agreement that we entered into with a former executive during the second quarter of 2020. This was partially offset by an increase in legal expenses.

We expect that selling, distribution and marketing expenses will increase due to the increase in marketing expenditures for Primatene Mist^®. Legal fees may fluctuate due to the timing of patent challenges and other litigation matters.

Total research and development expenses	$	18,122	$	16,149	$	1,973	12	%

Research and development expense increased due to an increase in salaries and personnel-related expenses as well as depreciation expense.

Research and development costs consist primarily of costs associated with the research and development of our product candidates including the cost of developing APIs. We expense research and development costs as incurred.

We have made, and expect to continue to make, substantial investments in research and development to expand our product portfolio and grow our business. We expect that research and development expenses will increase on an annual basis due to increased clinical trial costs related to our biosimilar and inhalation product candidates. These expenditures will include costs of APIs developed internally as well as APIs purchased externally, the cost of purchasing reference listed drugs and the costs of performing the clinical trials. As we undertake new and challenging research and development projects, we anticipate that the associated costs will increase significantly over the next several quarters and years. Over the past year, some of our ongoing clinical trials experienced short term interruptions in the recruitment of patients due to the COVID-19 pandemic, as hospitals prioritized their resources towards the COVID-19 pandemic and government imposed travel restrictions. These conditions may in turn delay spending and the results of these trials. Additionally, some clinical trials experienced increased expenses due to new protocols to protect participants from COVID-19.

We launched glucagon for injection emergency kit, 1mg in the first quarter of 2021. The increase in sales of Primatene Mist^® for the six months ended June 30, 2021, was primarily a result of the continued success of our nationwide digital, television and radio campaign, which will continue throughout 2021 as well as an expansion of our distribution channels throughout 2020 and 2021. The increase in sales of epinephrine was primarily due to the launch of our epinephrine injection, USP 30mg/30mL multiple dose vial product in the second quarter of 2020, as well as an increase in unit volumes, as a result of higher demand due to a market shortage for pre-filled syringes. The increase in sales of lidocaine was primarily due to an increase in unit volumes, as a result of a market shortage. Sales of enoxaparin increased $3.2 million due to an increase in unit volumes, which was primarily offset by lower average selling price as a competitor re-entered the market during the second quarter of 2021. The decrease in sales of Naloxone was primarily due a to lower average selling price as a result of a competitor entering the market. The decrease in sales of phytonadione was primarily due to lower unit volumes as a result of decreased market demand. The decrease in other finished pharmaceutical products was primarily due to lower unit volumes as a result of competitors returning to their normal distribution levels after being unable to supply market demands in 2020.

We anticipate that sales of naloxone and enoxaparin will continue to fluctuate in the future as a result of changing levels of competition.

Sales of API primarily depend on the timing of customer purchases. As a result of the amendment to the Supply Agreement with MannKind, we received the first payment of the amendment fee of $1.0 million in June 2021 and recognized $0.5 million in net revenues during the three months ended June 30, 2021. The remaining $0.5 million was recorded as a contract liability in our condensed consolidated balance sheet as of June 30, 2021 and will be recognized ratably in net revenues over the remaining quarters in 2021. The remaining balance of $1.0 million of the amendment fee is due January 2022 and relates to the amendments to the 2022 supply level and will be recognized ratably to net revenues in 2022.

Gross margins

The increase in sales of Primatene Mist^®, the launch of glucagon for injection emergency kit during the first quarter of 2021, as well as the launch of our epinephrine injection multiple dose vial in the second quarter of 2020, which are higher-margin products, helped increase our gross margins for the six months ended June 30, 2021. These increases in gross margins were partially offset by lower pricing and increased costs for enoxaparin, particularly the cost for heparin raw material, which is used as the starting material for enoxaparin.

Liquidity and Capital Resources

Cash Requirements and Sources

We need capital resources to maintain and expand our business. We expect our cash requirements to increase significantly in the foreseeable future as we sponsor clinical trials for, seek regulatory approvals of, and develop, manufacture and market our current development-stage product candidates and pursue strategic acquisitions of businesses or assets. Our future capital expenditures include projects to upgrade, expand, and improve our manufacturing facilities in the United States, China, and France. Our cash obligations include the principal and interest payments due on our existing loans and lease payments, as described below and throughout this Quarterly Report.

As of June 30, 2021, our foreign subsidiaries collectively held $8.4 million in cash and cash equivalents. Cash or cash equivalents held at foreign subsidiaries are not available to fund the parent company’s operations in the United States. We believe that our cash reserves, operating cash flows, and borrowing availability under our credit facilities will be sufficient to fund our operations for at least the next 12 months from the date of filing of this Quarterly Report on Form 10-Q. We expect additional cash flows to be generated in the longer term from future product introductions, although there can be no assurance as to the receipt of regulatory approval for any product candidates that we are developing or the timing of any product introductions, which could be lengthy or ultimately unsuccessful.

We maintain a shelf registration statement on Form S-3 pursuant to which we may, from time to time, sell up to an aggregate of $250 million of our common stock, preferred stock, depositary shares, warrants, units, or debt securities. If we require or elect to seek additional capital through debt or equity financing in the future, we may not be able to raise capital on terms acceptable to us or at all. To the extent we raise additional capital through the sale of equity or convertible debt securities, the issuance of such securities will result in dilution to our stockholders. If we are required and unable to raise additional capital when desired, our business, operating results and financial condition may be adversely affected.

Working capital increased by $18.9 million to $186.4 million at June 30, 2021, compared to $167.5 million at December 31, 2020.

Cash Flows from Operations

Sources and Use of Cash

Operating Activities

Net cash provided by operating activities was $55.0 million for the six months ended June 30, 2021, which included net income of $12.6 million. Non-cash items comprised primarily of $13.7 million of depreciation and amortization, and $10.9 million of share-based compensation expense.

Additionally, for the six months ended June 30, 2021, there was a net cash inflow from changes in operating assets and liabilities of $17.5 million, which resulted from an increase in accounts payable and accrued liabilities, which was partially offset by an increase in accounts receivable. Accounts payable and accrued liabilities increased primarily due to the timing of payments. The increase in accounts receivable was due to both increases in sales and the timing of sales.

Net cash provided by operating activities was $31.6 million for the six months ended June 30, 2020, which included net income of $2.1 million. Non-cash items were primarily comprised of $11.7 million of depreciation and amortization, and $11.8 million of share-based compensation expense. Additionally, for the six months ended June 30, 2020, there was a net cash inflow from changes in operating assets and liabilities of $4.3 million, which resulted from a decrease in inventory and an increase in accounts payable and accrued liabilities, which was partially offset by an increase in accounts receivable. The increase in accounts receivable was due to the timing of sales. Accounts payable and accrued liabilities decreased primarily due to the timing of payments.

Investing Activities

Net cash used in investing activities was $12.9 million for the six months ended June 30, 2021, primarily as a result of $13.4 million in purchases of property, plant, and equipment, which included $6.9 million incurred in the United States, $0.3 million in France, and $6.2 million in China.

Net cash used in investing activities was $18.8 million for the six months ended June 30, 2020, primarily as a result of $18.9 million in purchases of property, plant, and equipment, which included $3.3 million incurred in the United States, $2.2 million in France, and $13.4 million in China.

Financing Activities

Net cash used in financing activities was $11.8 million for the six months ended June 30, 2021, primarily as a result of $9.3 million used to purchase treasury stock and $0.8 million relating to the cash settlement of certain awards under the 2018 ANP equity plan in connection with the ANP restructuring. This was partially offset by $6.4 million in net proceeds from the settlement of share-based compensation awards under our equity plans. Additionally, we also made $8.0 million in principal payments on our long-term debt and line of credit.

Net cash provided by financing activities was $1.0 million for the six months ended June 30, 2020, primarily as a result of $18.2 million in net proceeds from the settlement of share-based compensation awards under our equity plans offset by $16.7 million used to purchase treasury stock. Additionally, we received $3.8 million from borrowings on our lines of credit, of which $3.1 million was converted into an equipment loan during the year. We also made $4.3 million in principal payments on our long-term debt.

Total debt	$	38,537	$	46,449	$	(7,912)

As of June 30, 2021, we had $56.0 million in unused borrowing capacity under revolving lines of credit and equipment lines of credit with Cathay Bank, East West Bank, and China Merchant Bank.

Subsequent to the end of the quarter ended June 30, 2021, we entered into a $70.0 million revolving line of credit with Capital One N.A., and terminated the lines of credit and equipment lines of credit with Cathay Bank and East West Bank.

Critical Accounting Policies

The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the notes to the financial statements. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions. A summary of our critical accounting policies is presented in Part II, Item 7, of our Annual Report on Form 10-K for the year ended December 31, 2020.

Recent Accounting Pronouncements

For information regarding recent accounting pronouncements, see “Part I – Item 1. Financial Statements – Notes to Condensed Consolidated Financial Statements – Summary of Significant Accounting Policies”.

Off-Balance Sheet Arrangements

We do not have any relationships or financial partnerships with unconsolidated entities, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts.

Government Regulation

Our products and facilities are subject to regulation by a number of federal and state governmental agencies. The FDA, in particular, maintains oversight of the formulation, manufacture, distribution, packaging, and labeling of all of our products. The Drug Enforcement Administration, or DEA, maintains oversight over our products that are considered controlled substances.

From June 14 through June 22, 2021, our Amphastar facility in Rancho Cucamonga, California was subject to a pre-approval inspection by the FDA. The inspection included a review of our corrective actions taken from the previous cGMP inspection in February 2019, as well as review of data to support our pending applications. The inspections resulted in multiple observations on Form 483. We fully responded to those observations on July 14, 2021. We believe that our responses to the observations will satisfy the requirements of the FDA and that no significant further actions will be necessary.

-39-

From July 12 through July 16, 2021, our IMS facility in South El Monte, California was subject to a post-approval inspection by the FDA. The inspection included a review progress and updates since the October 2019 pre-approval inspection. The inspection resulted in no Form 483 findings. No further actions will be necessary.

From July 12 through July 14, 2021, our Armstrong facility in Canton, Massachusetts was subject to a routine inspection by the FDA. The inspection included a review of compliance with FDA regulations relating to Good Manufacturing Practices. The inspection resulted in no Form 483 findings. No further actions will be necessary.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Except for the broad, ongoing effects of the COVID-19 pandemic as a result of its negative impact on the global economy and financial markets, there have been no material changes in market risk from the information provided in our Annual Report on Form 10-K for the year ended December 31, 2020. We are exposed to market risk in the ordinary course of business. Market risk represents the potential loss arising from adverse changes in the value of financial instruments. The risk of loss is assessed based on the likelihood of adverse changes in fair values, cash flows or future earnings. We are exposed to market risk for changes in the market values of our investments (Investment Risk), the impact of interest rate changes (Interest Rate Risk), and the impact of foreign currency exchange changes (Foreign Currency Exchange Risk).

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer, our principal executive and principal financial officers, respectively, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were effective (a) to ensure that information that we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and (b) to include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management overriding of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

ITEM 1. LEGAL PROCEEDINGS

For information regarding legal proceedings, see “Part I – Item 1. Financial Statements – Notes to Condensed Consolidated Financial Statements – Litigation”.

ITEM 1A. RISK FACTORS

Except as noted below, there were no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission on March 15, 2021.

Our business may be adversely affected by the ongoing COVID-19 pandemic or other epidemics.

The ongoing COVID-19 pandemic, including the recent Delta variant, has continued to impact worldwide economic activity and financial markets. While three vaccines have received Emergency Use Authorization from the FDA, the COVID-19 pandemic remains a challenge to our business until it is abated. Mass and rapid production of the vaccines, for example, has placed increased pressure on the availability of supplies that are also used in our products, such as glass vials and needles. The COVID-19 pandemic is imposing additional burdens on our business to comply with regulations imposed by the State of California. The COVID-19 pandemic may also disrupt the operations of our customers, suppliers and partners for an indefinite period of time, including as a result of travel restrictions and/or business shutdowns, all of which could negatively impact our business and results of operations, including cash flows. Disruptions to our manufacturing partners and suppliers could result in disruption to the production of our products and failure to satisfy demand. More generally, the outbreak of COVID-19 could adversely affect economies and financial markets globally and nationally, potentially leading to an economic downturn, which could decrease spending and adversely affect demand for our products and harm our business and results of operations. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a result of its global economic impact, including any recession that has occurred or may occur in the future. Specifically, difficult macroeconomic conditions, increased and prolonged unemployment or a decline in business confidence as a result of the COVID-19 pandemic, could have a continuing adverse effect on the demand for some of our products. The degree of impact of the COVID-19 pandemic on our business will depend on several factors, such as the duration and the extent of the pandemic, as well as actions taken by governments, businesses, and consumers in response to the pandemic, all of which continue to evolve and remain uncertain at this time.

As a result of the consequences of the COVID-19 pandemic, FDA has issued various COVID-19 related guidance documents applicable to biopharmaceutical manufacturers and clinical trial sponsors. For example, in March 2020, the FDA issued a guidance, which the FDA subsequently updated, on conducting clinical trials during the pandemic, which describes a number of considerations for sponsors of clinical trials impacted by the pandemic, including the requirement to include in the clinical trial report contingency measures implemented to manage the clinical trial, among others. The FDA also issued a guidance on good manufacturing practice considerations for responding to COVID-19 infection in employees in drug products manufacturing, and a guidance on review timelines for applicant responses to Complete Response Letters when a facility assessment is needed during the COVID-19 public health emergency. These and future guidance documents and regulatory requirements, including future legislation, may require us to develop and implement new policies and procedures, make significant adjustments to our clinical trials, or increase the amount time and resources needed for regulatory compliance, which may impact our clinical development plans and timelines.

Some of our ongoing clinical trials have experienced short term interruptions in the recruitment of patients due to the COVID-19 pandemic, as hospitals prioritize their resources toward the COVID-19 pandemic and governments impose travel restrictions. Additionally, protocols at certain clinical sites have changed which could slow down the pace of clinical trials while also increasing their cost. These conditions may in turn delay spending and delay the results of these trials. Additionally, certain suppliers have delayed shipments to us in 2020 and 2021. These delays may have been caused by manufacturing disruptions due to the COVID-19 pandemic. None of these delays caused delays in our manufacturing to date, but future delays could cause manufacturing disruptions at our factories and could also cause lost

-42-

sales.

It is not possible at this time to estimate the complete impact that the COVID-19 pandemic could have on our business, as the impact will depend on future developments, which are highly uncertain and cannot be predicted. Infections may resurge or become more widespread and the limitation on our ability to travel and timely sell and distribute our products, as well as any closures or supply disruptions, may be extended for longer periods of time, all of which would have a negative impact on our business, financial condition and operating results. We will continue to monitor the impact of the COVID-19 pandemic on all aspects of our business.

Because a portion of our manufacturing takes place in China, a significant disruption in the construction or operation of our manufacturing facility in China, political unrest in China, tariffs, impact of outbreaks of health epidemics, such as the COVID-19 pandemic, or changes in social, political, trade, health, economic, environmental, or climate-related conditions or in laws, regulations and policies governing foreign trade could materially and adversely affect our business, financial condition and results of operations.

We currently manufacture the starting material for Amphadase^® and enoxaparin as well as the APIs for isoproterenol and nitroprusside at our manufacturing facility in China, and we plan to use this facility to manufacture several of the APIs for products in our pipeline. Additionally, we intend to continue to invest in the expansion of this manufacturing facility. Our manufacturing facility and operations in China involve significant risks, including:

●

disruptions in the construction of the manufacturing facility;

●

interruptions to our operations in China or the inability of our manufacturing facility to produce adequate quantities of raw materials or APIs to meet our needs as a result of natural catastrophic events or other causes beyond our control such as power disruptions or widespread disease outbreaks, including the recent outbreaks that impact animal-derived products, such as the importation of pig-derived crude heparin from countries impacted by the African swine flu, and outbreak of the COVID-19 pandemic, which has resulted in and may in the future result in, business closures, transportation restrictions, import and export complications, and otherwise cause shortages in the supply of raw materials or cause disruptions in our manufacturing capability;

●

product supply disruptions and increased costs as a result of heightened exposure to changes in the policies of the Chinese government, political unrest or unstable economic conditions in China;

●

the imposition of tariffs or other trade barriers as a result of changes in social, political, and economic conditions or in laws, regulations, and policies governing foreign trade, including the tariffs previously implemented and additional tariffs that have been proposed by the U.S. government on various imports from China and by the Chinese government on certain U.S. goods, the scope and duration of which, if implemented, remain uncertain;

●

the nationalization or other expropriation of private enterprises or intellectual property by the Chinese government, which could result in the total loss of our investment in China; and

●

interruptions to our manufacturing or business operations resulting from geo-political actions, including war and terrorism, natural disasters including earthquakes, typhoons, floods, and fires, or outbreaks of health epidemics such as coronavirus, or outbreaks in livestock or animals that impact or restrict importation, use, or distribution of animal-derived products.

Any of these matters could materially and adversely affect our business and results of operations. These interruptions or failures could impair our ability to operate our business, impede the commercialization of our product candidates or delay the introduction of new products, impact our product quality, or impair our competitive position.

We are actively monitoring and assessing the potential impact of the COVID-19 pandemic. This includes evaluating the impact on our employees, suppliers, and logistics providers as well as evaluating governmental actions being taken to curtail the spread of the virus. While the Chinese government has been relaxing work restrictions, at this time, it is unclear if the Chinese government will reinstate restrictions or if further restrictions will be put into place by the

-43-

government. In addition, many countries have placed significant bans on travel to and from China, with many countries and airlines suspending flights to and from mainland China. Any material adverse effect on our employees, suppliers, and logistics providers could have a material adverse effect on our manufacturing operations in China or the supply of raw materials or APIs originating from China.

Our epinephrine prefilled syringe product is marketed without FDA approval and may be subject to enforcement actions by the FDA.

Our epinephrine prefilled syringe prescription product is marketed without FDA approval. This products, like many other prescription drugs on the market that have not been formally evaluated as being effective by the FDA, contain active ingredients that were first marketed prior to the enactment of the Federal Food, Drug, and Cosmetic Act, or FFDCA. The FDA has assessed this product in a program known as the “Prescription Drug Wrap-Up” and has stated that this drug cannot be lawfully marketed unless they comply with certain “grandfather” exceptions to the definition of “new drug” in the FFDCA. These exceptions have been strictly construed by FDA and by the courts, and the FDA has stated that it is unlikely that any of the unapproved prescription drugs on the market, including our drug, qualify for the exceptions. At any time, the FDA may require that our unapproved prescription drug be submitted for approval and may direct us to recall this product and/or cease marketing the product until they are approved. The FDA may also take enforcement actions based on our marketing of this unapproved product, including but not limited to the issuance of an untitled letter or a warning letter, judicial action seeking an injunction, product seizure and/or civil or criminal penalties. The enforcement posture could change at any time and our ability to market such drugs could terminate with little or no notice. Moreover, if our competitors seek and obtain approval and market FDA-approved prescription products that compete against our unapproved prescription product, we would be subject to a higher likelihood that the FDA may seek to take action against our unapproved product. Such competitors have brought and may bring claims against us alleging unfair competition or related claims.

As a result of our meetings with the FDA in 2009, we decided to discontinue all of our products that were subject to the Prescription Drug Wrap-Up program, with the exception of epinephrine in vial form. These products were all produced at our subsidiary, IMS. During the third quarter of 2010, the FDA requested that we reintroduce several of the withdrawn products to help address a national drug shortage, while we prepared and filed applications for approval of the products. Between August and October 2010, we reintroduced our epinephrine prefilled syringes.

In February 2017, the FDA requested that we discontinue the manufacturing and distribution of our epinephrine injection, USP vial product, which had been marketed under the “grandfather” exception to the “FDA’s Prescription Drug Wrap-Up program”. We discontinued selling this product in the second quarter of 2017. In April 2020, the FDA granted approval of our Epinephrine Injection, USP 30mg/mL Multiple Dose Vial, and launched the product in May 2020.

The FDA granted approval of our Atropine Sulfate Injection 0.1mg/mL in the 10mL Luer-Jet^® Prefilled Syringe in October 2020, our Dextrose Injection 50% in the 50mL Luer-Jet^® Prefilled Syringe in March 2021 and our Morphine Sulfate Injection USP, 1mg/mL 30mL in April 2021.

Our only unapproved product currently on the market is epinephrine prefilled syringes. For the years ended December 31, 2020, 2019, and 2018, we recorded net revenues of $13.2 million, $13.9 million, and $10.1 million, respectively, for epinephrine prefilled syringes and for the six months ended June 30, 2021 and 2020, we recorded net revenues of $12.3 million and $8.3 million, respectively, for this product. We have filed an NDA with respect to our remaining unapproved product in order to mitigate all risk associated with the marketing of unapproved drug products. Prior to the approval of our NDA submission, we continue to operate in compliance with the FDA Compliance Policy Guide, CPG Sec. 440.100 Marketed New Drugs Without Approved NDAs and ANDAs.
