Accounting Policies [Abstract]
Change in Functional Currency	Change in Functional Currency Effective January 1, 2023, the Company adopted the U.S. dollar as its functional currency for Acacia subsidiaries. Prior to January 1, 2023, the functional currency of the Acacia was the Pound Sterling. The change in functional currency of Acacia is due to the integration of Acacia and the legacy Eagle businesses being completed beginning in the first quarter of 2023. As a result of the integration, the nature and volume of the UK operations and funding received by the UK entities are denominated in the U.S. dollar. Therefore, the UK operations of Acacia are considered integrated and parent dependent. The Company’s financial results have been reported in U.S. dollars. The effect of a change in the functional currency is accounted for prospectively. More specifically, translation adjustments for prior periods are not removed from equity and the translated amounts for nonmonetary assets at the end of the prior period became the accounting basis for those assets, effective January 1, 2023. Exchange differences arising from the translation that were previously recognized in other comprehensive income are not reclassified from equity to profit and loss until the disposal of the operations attributable to Acacia.
Use of Estimates	Use of Estimates These condensed consolidated financial statements are presented in U.S. dollars and are prepared in accordance with U.S. GAAP. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements including disclosure of gross to net estimates as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period and accompanying notes. Our critical accounting policies are those that are both most important to our financial condition and results of operations and also require the most difficult, subjective or complex judgments on the part of management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. As of the date of issuance of these condensed consolidated financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, assumptions and judgments or revise the carrying amount of our assets or liabilities. Because of the uncertainty of factors surrounding the estimates or judgments used in the preparation of the condensed consolidated financial statements, actual results may materially vary from these estimates, and any such differences may be material to our condensed consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents are held in United States financial institutions. The carrying amount of cash and cash equivalents approximates its fair value due to its short-term nature. We, at times, maintain balances with financial institutions in excess of the Federal Deposit Insurance Corporation (“FDIC”) limit.
Fair Value Measurements	Fair Value Measurements U.S. GAAP establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: •Level 1: Quoted prices in active markets for identical assets or liabilities. •Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. •Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying amount of interest-bearing cash, cash equivalents, accounts receivable and accounts payable approximate fair value due to their life being short term in nature, and are classified as Level 1 for all periods presented. We recognize transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the six months ended June 30, 2023. Our investment in Enalare Therapeutics Inc., related acquisition rights and forward liability were classified as Level 3. We used a probability factor to value the asset related to the acquired acquisition rights based on management's best estimate, including the probability of completion of certain development milestones. The equity stake was accounted for as non-readily determinable fair value (“RDFV”) investment. The equity investment and acquisition rights were reported at fair value as of June 30, 2023. Refer to Note 14, Investment in Enalare Therapeutics Inc. for further information. Our investment in restricted shares of common stock of Syros, following the merger of Tyme Technologies, Inc. and Syros on September 16, 2022, are classified as Level 1. Refer to Note 12, License and Collaboration Agreements for further details. The fair value of debt is classified as Level 2 for the periods presented and approximates its fair value due to the variable interest rate.
Intangible Assets, net	Intangible Assets, netWe review the recoverability of our finite-lived intangible assets and long-lived assets for indicators of impairments. Events or circumstances that may require an impairment assessment include negative clinical trial results, a significant decrease in the market price of the asset, or a significant adverse change in legal factors or the manner in which the asset is used. If such indicators are present, we assess the recoverability of affected assets by determining if the carrying amount of such assets is less than the sum of the undiscounted future cash flows of the assets. If such assets are found to not be recoverable, we measure the amount of the impairment by comparing the carrying amount of the assets to their respective fair value. We determined that no indicators of impairment of finite-lived intangible assets or long-lived assets existed as of June 30, 2023.
Goodwill	GoodwillGoodwill represents the excess of purchase price over the fair value of net assets acquired in the Eagle Biologics and Acacia acquisitions. Goodwill is not amortized, but is evaluated for impairment on an annual basis, in the fourth quarter, or more frequently if events or changes in circumstances indicate that the reporting unit’s goodwill is less than its carrying amount.
Concentration of Major Customers and Vendors	Concentration of Major Customers and Vendors The Company is exposed to risks associated with extending credit to customers related to the sale of products. The Company does not require collateral to secure amounts due from its customers. The Company uses an expected loss methodology to calculate allowances for trade receivables. The Company's measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The Company does not currently have a material allowance for collectible trade receivables. Further, the Company is dependent on its commercial partner to market and sell Bendeka; therefore, the Company's future revenues are highly dependent on the collaboration and distribution arrangement with Teva. Teva markets Bendeka through a license agreement with the Company. Pursuant to that license agreement, Teva pays the Company a royalty based on net sales of the product and also purchases the product from the Company. A disruption in this arrangement, caused by, among other things, a supply disruption, loss of exclusivity or the launch of a superior product would have a material adverse effect on our financial position, results of operations and cash flows.
Inventories	Inventories Inventories are recorded at the lower of cost and net realizable value, with cost determined on a first-in first-out basis. We periodically review the composition of inventory in order to identify obsolete, slow-moving or otherwise non-saleable items. If these items are observed and there are no alternate uses for the inventory, we will record a write-down to the lower of cost and net realizable value in the period that the decline in value is first recognized.
Research and Development Expense	Research and Development Expense Costs for research and development are charged to expense as incurred and include; employee-related expenses including salaries, benefits, travel and stock-based compensation expense for research and development personnel; expenses incurred under agreements with contract research organizations, contract manufacturing organizations and service providers that assist in conducting clinical and preclinical studies; costs associated with preclinical activities and development activities, costs associated with regulatory operations; and depreciation expense for assets used in research and development activities. Costs for certain development activities, such as in licensing intellectual property related to new projects, clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to us by our vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the patterns of costs incurred, and are reflected in the condensed consolidated financial statements as prepaid expenses or accrued expenses as deemed appropriate. Recoveries of previously recognized research and development expenses from third parties are recorded as a reduction to research and development expense in the period it becomes realizable.
Advertising and Marketing	Advertising and MarketingAdvertising and marketing costs are expensed as incurred.
Income Taxes	Income Taxes We account for income taxes using the liability method in accordance with ASC 740 - Income Taxes (“ASC 740”). Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities and are measured by applying enacted rates and laws to taxable years in which differences are expected to be recovered or settled. Further, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income (loss) in the period that the rate changes. A valuation allowance is required when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. ASC 740 also prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that a company has taken or expects to take on a tax return, including a decision whether to file or not file a return in a particular jurisdiction. We recognize any interest and penalties accrued related to unrecognized tax benefits as income tax expense.
Revenue Recognition	Revenue Recognition Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606 - Revenue from Contracts with Customers ("ASC 606"), the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue. Product revenue - The Company recognizes net revenue on sales to its commercial partners and to end users. In each instance, revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Receivables from our product sales have payment terms ranging from 30 to 90 days with select extended terms to wholesalers on certain product purchases. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price generally utilizing the expected value method to which the Company expects to be entitled. As such, revenue on sales to end users for Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin are recorded net of chargebacks, rebates, returns, prompt pay discounts, wholesaler fees and other deductions. Our products are contracted with a limited number of oncology distributors and hospital buying groups with narrow differences in ultimate realized contract prices used to estimate our allowance for chargebacks and rebate reserves. The Company has a product returns policy on some of its products that allows the customer to return pharmaceutical products within a specified period of time both prior to and subsequent to the product’s expiration date. The Company's estimate of the provision for returns is analyzed quarterly and is based upon many factors, including historical experience of actual returns and analysis of the level of inventory in the distribution channel, if any. The Company has terms on sales of Ryanodex by which the Company does not accept returns. The returns policy is subject to change at any time and as the Company determines it to be, without notice. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration are made generally using the expected value method and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company believes that the estimates it has established are reasonable based upon current facts and circumstances. Applying different judgments to the same facts and circumstances could result in the estimated amounts to vary. Components of Gross-to-Net (GTN) Estimates Chargebacks: Chargebacks are discounts that occur when certain contracted customers, including group purchasing organizations (“GPOs”), public health service institutions and federal government entities purchasing via the Federal Supply Schedule, purchase from the Company's distributors. The Company's distributors purchase products from us at invoice price, then resell the product to certain contracted customers on the basis of prices negotiated between us and the providers. The difference between the distributors’ purchase price and the typically lower certain contracted customers’ purchase price is refunded to the distributors through a chargeback credit. We record estimates for these chargebacks at the time of sale as deductions from gross revenues, with corresponding adjustments to our accounts receivable reserves and allowances. The provision for chargebacks is the most significant provision in the context of the Company’s gross-to-net adjustments in the determination of net revenue. Chargebacks are estimated based on payer mix and contracted price, adjusted for current period assumptions. Commercial and Medicaid Rebates: The Company contracts with government agencies or collectively, third-party payors, so that Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. The current liability is included in accrued expenses and other current liabilities on the consolidated balance sheets. The Company estimates the rebates that it will provide to third-party payors based upon (i) the Company’s contracts with these third-party payors, (ii) the government mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payer mix, and (iv) information obtained from the Company’s distributors. The information that the Company also considers when establishing its rebate reserves are purchases by customers, projected annual sales for customers, actual rebates payments made, processing time lags, and for indirect rebates, the level of inventory in the distribution channel that will be subject to indirect rebates. We do not provide incentives designed to increase shipments to our customers that we believe would result in out-of-the-ordinary course of business inventory for them. The Company regularly reviews and monitors estimated or actual customer inventory information at its largest distributors for its key products to ascertain whether customer inventories are in excess of ordinary course of business levels. Product Returns: The Company's provision for product returns based on the factors noted above generally encompass a time range from 12 to 48 months after revenue is recognized. The Company’s distributors have the right to return unopened unprescribed Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin during certain time periods around the period beginning prior to the labeled expiration date and ending after the labeled expiration date. The Company estimates future product returns on sales of Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin based on: (i) data provided to the Company by its distributors (including weekly reporting of distributors’ sales and inventory held by distributors that provided the Company with visibility into the distribution channel in order to determine what quantities were sold to retail pharmacies and other providers), (ii) data provided to the Company by a third-party data provider which collects and publishes prescription data, and other third parties, (iii) historical industry information regarding return rates for similar pharmaceutical products, (iv) the estimated remaining shelf life of Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin previously shipped and currently being shipped to distributors and (v) contractual agreements intended to limit the amount of inventory maintained by the Company’s distributors. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses and other current liabilities on the consolidated balance sheets. Wholesaler fees and other incentives: The Company generally provides invoice discounts on Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin sales to its distributors for prompt payment and fees for distribution services, such as fees for certain data that distributors provide to the Company. The payment terms for sales to distributors generally include a 2% discount for prompt payment which is generally defined in invoice terms as a range from 15 to 45 days, while the fees for distribution services are based on contractual rates agreed with the respective distributors. Based on historical data, the Company expects its distributors to earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized. In certain cases, the Company may record the fees as accrued expenses if the Company expects that the fees will be paid rather than deducted by the distributor. Royalty Revenue — The Company recognizes revenue from license arrangements with its commercial partners' net sales of products. Royalties are recognized as earned in accordance with contract terms when they can be reasonably estimated and collectability is reasonably assured. The Company's commercial partners are obligated to report their net product sales and the resulting royalty due to the Company within 25 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, the Company accrues royalty revenue each quarter and subsequently determines a true-up when it receives royalty reports from its commercial partners. Historically, these true-up adjustments have been immaterial. Our receivables from royalty revenue are due 45-days from the end of the quarter. License and other revenue — The Company analyzes each element of its licensing agreements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to us of non-refundable up-front license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. The Company recognizes revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer. If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. The Company recognizes sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, the Company determined that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, the Company assesses each milestone to determine the probability and substance behind achieving each milestone. Given the inherent uncertainty of the occurrence of these future events, the Company will not recognize revenue from the milestone until there is not a high probability of a reversal of revenue, which typically occurs near or upon achievement of the event. When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2023.
Stock-Based Compensation	Stock-Based Compensation The Company utilizes stock-based compensation in the form of stock options, restricted stock units ("RSUs") and performance-based stock units ("PSUs"), each of which may be granted separately or in tandem with other awards. Compensation expense is recognized in the Consolidated Statements of operations based on the estimated fair value of the awards at grant date ratably over the requisite service period, which generally equals the vesting period of the award. The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. The Company uses the Black-Scholes option pricing formula for determining the grant-date fair value of such awards. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock and (c) the risk-free interest rate for the expected term of the option. The Company may also grant performance-based stock awards to employees from time-to-time based on the achievement of a market or performance condition. The grant-date fair value of awards that vest based on achievement of certain market conditions are determined using a Monte Carlo simulation technique. The grant-date fair value of awards that vest based on achievement of certain performance condition are determined using the accelerated attribution method once it is probable that the performance condition will be achieved.
Earnings Per Share	Earnings Per Share Basic earnings per common share is computed using the weighted average number of shares outstanding during the period. Diluted earnings per share is computed in a manner similar to the basic earnings per share, except that the weighted-average number of shares outstanding is increased to include all common shares, including those with the potential to be issued by virtue of options. Diluted earnings per share contemplate a complete conversion to common shares of all convertible instruments only if they are dilutive in nature with regards to earnings per share, as calculated under the treasury method.
Recent Accounting Pronouncements	Recent Accounting Pronouncements There are several new accounting pronouncements issued by the FASB that we have adopted or will adopt, as applicable. We do not believe any of these accounting pronouncements have had, or will have, a material impact on our condensed consolidated financial statements or disclosures.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2023

Effective January 1, 2023, the Company adopted the U.S. dollar as its functional currency for Acacia subsidiaries. Prior to January 1, 2023, the functional currency of the Acacia was the Pound Sterling.

The change in functional currency of Acacia is due to the integration of Acacia and the legacy Eagle businesses being completed beginning in the first quarter of 2023. As a result of the integration, the nature and volume of the UK operations and funding received by the UK entities are denominated in the U.S. dollar. Therefore, the UK operations of Acacia are considered integrated and parent dependent.

The Company’s financial results have been reported in U.S. dollars. The effect of a change in the functional currency is accounted for prospectively. More specifically, translation adjustments for prior periods are not removed from equity and the translated amounts for nonmonetary assets at the end of the prior period became the accounting basis for those assets, effective January 1, 2023. Exchange differences arising from the translation that were previously recognized in other comprehensive income are not reclassified from equity to profit and loss until the disposal of the operations attributable to Acacia.

Use of Estimates

These condensed consolidated financial statements are presented in U.S. dollars and are prepared in accordance with U.S. GAAP. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements including disclosure of gross to net estimates as of the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period and accompanying notes. Our critical accounting policies are those that are both most important to our financial condition and results of operations and also require the most difficult, subjective or complex judgments on the part of management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. As of the date of issuance of these condensed consolidated financial statements, we are not aware of any specific event or circumstance that would require us to update our estimates, assumptions and judgments or revise the carrying amount of our assets or liabilities. Because of the uncertainty of factors surrounding the estimates or judgments used in the preparation of the condensed consolidated financial statements, actual results may materially vary from these estimates, and any such differences may be material to our condensed consolidated financial statements.

Cash and Cash Equivalents

We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents are held in United States financial institutions. The carrying amount of cash and cash equivalents approximates its fair value due to its short-term nature.

We, at times, maintain balances with financial institutions in excess of the Federal Deposit Insurance Corporation (“FDIC”) limit.

Fair Value Measurements

U.S. GAAP establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

•Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The carrying amount of interest-bearing cash, cash equivalents, accounts receivable and accounts payable approximate fair value due to their life being short term in nature, and are classified as Level 1 for all periods presented.

We recognize transfers between levels within the fair value hierarchy, if any, at the end of each quarter. There were no transfers in or out of Level 1, Level 2 or Level 3 during the six months ended June 30, 2023.

Our investment in Enalare Therapeutics Inc., related acquisition rights and forward liability were classified as Level 3. We used a probability factor to value the asset related to the acquired acquisition rights based on management's best estimate, including the probability of completion of certain development milestones. The equity stake was accounted for as non-readily determinable fair value (“RDFV”) investment. The equity investment and acquisition rights were reported at fair value as of June 30, 2023. Refer to Note 14, Investment in Enalare Therapeutics Inc. for further information.

Our investment in restricted shares of common stock of Syros, following the merger of Tyme Technologies, Inc. and Syros on September 16, 2022, are classified as Level 1. Refer to Note 12, License and Collaboration Agreements for further details.

The fair value of debt is classified as Level 2 for the periods presented and approximates its fair value due to the variable interest rate.

Intangible Assets, net

Intangible Assets, netWe review the recoverability of our finite-lived intangible assets and long-lived assets for indicators of impairments. Events or circumstances that may require an impairment assessment include negative clinical trial results, a significant decrease in the market price of the asset, or a significant adverse change in legal factors or the manner in which the asset is used. If such indicators are present, we assess the recoverability of affected assets by determining if the carrying amount of such assets is less than the sum of the undiscounted future cash flows of the assets. If such assets are found to not be recoverable, we measure the amount of the impairment by comparing the carrying amount of the assets to their respective fair value. We determined that no indicators of impairment of finite-lived intangible assets or long-lived assets existed as of June 30, 2023.

Goodwill

GoodwillGoodwill represents the excess of purchase price over the fair value of net assets acquired in the Eagle Biologics and Acacia acquisitions. Goodwill is not amortized, but is evaluated for impairment on an annual basis, in the fourth quarter, or more frequently if events or changes in circumstances indicate that the reporting unit’s goodwill is less than its carrying amount.

Concentration of Major Customers and Vendors

The Company is exposed to risks associated with extending credit to customers related to the sale of products. The Company does not require collateral to secure amounts due from its customers. The Company uses an expected loss methodology to calculate allowances for trade receivables. The Company's measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The Company does not currently have a material allowance for collectible trade receivables.

Further, the Company is dependent on its commercial partner to market and sell Bendeka; therefore, the Company's future revenues are highly dependent on the collaboration and distribution arrangement with Teva.

Teva markets Bendeka through a license agreement with the Company. Pursuant to that license agreement, Teva pays the Company a royalty based on net sales of the product and also purchases the product from the Company. A disruption in this arrangement, caused by, among other things, a supply disruption, loss of exclusivity or the launch of a superior product would have a material adverse effect on our financial position, results of operations and cash flows.

Inventories

Inventories are recorded at the lower of cost and net realizable value, with cost determined on a first-in first-out basis. We periodically review the composition of inventory in order to identify obsolete, slow-moving or otherwise non-saleable items. If these items are observed and there are no alternate uses for the inventory, we will record a write-down to the lower of cost and net realizable value in the period that the decline in value is first recognized.

Research and Development Expense

Costs for research and development are charged to expense as incurred and include; employee-related expenses including salaries, benefits, travel and stock-based compensation expense for research and development personnel; expenses incurred under agreements with contract research organizations, contract manufacturing organizations and service providers that assist in conducting clinical and preclinical studies; costs associated with preclinical activities and development activities, costs associated with regulatory operations; and depreciation expense for assets used in research and development activities.

Costs for certain development activities, such as in licensing intellectual property related to new projects, clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to us by our vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the patterns of costs incurred, and are reflected in the condensed consolidated financial statements as prepaid expenses or accrued expenses as deemed appropriate. Recoveries of previously recognized research and development expenses from third parties are recorded as a reduction to research and development expense in the period it becomes realizable.

Advertising and Marketing

Advertising and MarketingAdvertising and marketing costs are expensed as incurred.

Income Taxes

We account for income taxes using the liability method in accordance with ASC 740 - Income Taxes (“ASC 740”). Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities and are measured by applying enacted rates and laws to taxable years in which differences are expected to be recovered or settled. Further, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income (loss) in the period that the rate changes. A valuation allowance is required when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. ASC 740 also prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that a company has taken or expects to take on a tax return, including a decision whether to file or not file a return in a particular jurisdiction. We recognize any interest and penalties accrued related to unrecognized tax benefits as income tax expense.

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606 - Revenue from Contracts with Customers ("ASC 606"), the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Product revenue - The Company recognizes net revenue on sales to its commercial partners and to end users. In each instance, revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Receivables from our product sales have payment terms ranging from 30 to 90 days with select extended terms to wholesalers on certain product purchases.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or services to a customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price generally utilizing the expected value method to which the Company expects to be entitled. As such, revenue on sales to end users for Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin are recorded net of chargebacks, rebates, returns, prompt pay discounts, wholesaler fees and other deductions. Our products are contracted with a limited number of oncology distributors and hospital buying groups with narrow differences in ultimate realized contract prices used to estimate our allowance for chargebacks and rebate reserves. The Company has a product returns policy on some of its products that allows the customer to return pharmaceutical products within a specified period of time both prior to and subsequent to the product’s expiration date. The Company's estimate of the provision for returns is analyzed quarterly and is based upon many factors, including historical experience of actual returns and analysis of the level of inventory in the distribution channel, if any. The Company has terms on sales of Ryanodex by which the Company does not accept returns. The returns policy is subject to change at any time and as the Company determines it to be, without notice. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration are made generally using the expected value method and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company believes that the estimates it has established are reasonable based upon current facts and circumstances. Applying different judgments to the same facts and circumstances could result in the estimated amounts to vary.

Components of Gross-to-Net (GTN) Estimates

Chargebacks: Chargebacks are discounts that occur when certain contracted customers, including group purchasing organizations (“GPOs”), public health service institutions and federal government entities purchasing via the Federal Supply Schedule, purchase from the Company's distributors. The Company's distributors purchase products from us at invoice price, then resell the product to certain contracted customers on the basis of prices negotiated between us and the providers. The difference between the distributors’ purchase price and the typically lower certain contracted customers’ purchase price is refunded to the distributors through a chargeback credit. We record estimates for these chargebacks at the time of sale as deductions from gross revenues, with corresponding adjustments to our accounts receivable reserves and allowances.

The provision for chargebacks is the most significant provision in the context of the Company’s gross-to-net adjustments in the determination of net revenue. Chargebacks are estimated based on payer mix and contracted price, adjusted for current period assumptions.

Commercial and Medicaid Rebates: The Company contracts with government agencies or collectively, third-party payors, so that Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin will be eligible for purchase by, or partial or full reimbursement from, such third-party payors. The Company estimates the rebates it will provide to third-party payors and deducts these estimated amounts from total gross product revenues at the time the revenues are recognized. These reserves are recorded in the same period in which the revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. The current liability is included in accrued expenses and other current liabilities on the consolidated balance sheets. The Company estimates the rebates that it will provide to third-party payors based upon (i) the Company’s contracts with these third-party payors, (ii) the government mandated discounts applicable to government-funded programs, (iii) a range of possible outcomes that are probability-weighted for the estimated payer mix, and (iv) information obtained from the Company’s distributors.

The information that the Company also considers when establishing its rebate reserves are purchases by customers, projected annual sales for customers, actual rebates payments made, processing time lags, and for indirect rebates, the level of inventory in the distribution channel that will be subject to indirect rebates. We do not provide incentives designed to increase shipments to our customers that we believe would result in out-of-the-ordinary course of business inventory for them. The Company regularly reviews and monitors estimated or actual customer inventory information at its largest distributors for its key products to ascertain whether customer inventories are in excess of ordinary course of business levels.

Product Returns: The Company's provision for product returns based on the factors noted above generally encompass a time range from 12 to 48 months after revenue is recognized. The Company’s distributors have the right to return unopened unprescribed Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin during certain time periods around the period beginning prior to the labeled expiration date and ending after the labeled expiration date. The Company estimates future product returns on sales of Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin based on: (i) data provided to the Company by its distributors (including weekly reporting of distributors’ sales and inventory held by distributors that provided the Company with visibility into the distribution channel in order to determine what quantities were sold to retail pharmacies and other providers), (ii) data provided to the Company by a third-party data provider which collects and publishes prescription data, and other third parties, (iii) historical industry information regarding return rates for similar pharmaceutical products, (iv) the estimated remaining shelf life of Pemfexy, Belrapzo, Barhemsys, Byfavo, and vasopressin previously shipped and currently being shipped to distributors and (v) contractual agreements intended to limit the amount of inventory maintained by the Company’s distributors. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses and other current liabilities on the consolidated balance sheets.

Wholesaler fees and other incentives: The Company generally provides invoice discounts on Pemfexy, Belrapzo, Ryanodex, Barhemsys, Byfavo, and vasopressin sales to its distributors for prompt payment and fees for distribution services, such as fees for certain data that distributors provide to the Company. The payment terms for sales to distributors generally include a 2% discount for prompt payment which is generally defined in invoice terms as a range from 15 to 45 days, while the fees for distribution services are based on contractual rates agreed with the respective distributors. Based on historical data, the

Company expects its distributors to earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized. In certain cases, the Company may record the fees as accrued expenses if the Company expects that the fees will be paid rather than deducted by the distributor.

Royalty Revenue — The Company recognizes revenue from license arrangements with its commercial partners' net sales of products. Royalties are recognized as earned in accordance with contract terms when they can be reasonably estimated and collectability is reasonably assured. The Company's commercial partners are obligated to report their net product sales and the resulting royalty due to the Company within 25 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, the Company accrues royalty revenue each quarter and subsequently determines a true-up when it receives royalty reports from its commercial partners. Historically, these true-up adjustments have been immaterial. Our receivables from royalty revenue are due 45-days from the end of the quarter.

License and other revenue — The Company analyzes each element of its licensing agreements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to us of non-refundable up-front license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. The Company recognizes revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The Company recognizes sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, the Company determined that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, the Company assesses each milestone to determine the probability and substance behind achieving each milestone. Given the inherent uncertainty of the occurrence of these future events, the Company will not recognize revenue from the milestone until there is not a high probability of a reversal of revenue, which typically occurs near or upon achievement of the event.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph 606-10-32-18, the Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of June 30, 2023.

Stock-Based Compensation

The Company utilizes stock-based compensation in the form of stock options, restricted stock units ("RSUs") and performance-based stock units ("PSUs"), each of which may be granted separately or in tandem with other awards.

Compensation expense is recognized in the Consolidated Statements of operations based on the estimated fair value of the awards at grant date ratably over the requisite service period, which generally equals the vesting period of the award.

The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. The Company uses the Black-Scholes option pricing formula for determining the grant-date fair value of such awards. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock and (c) the risk-free interest rate for the expected term of the option.

The Company may also grant performance-based stock awards to employees from time-to-time based on the achievement of a market or performance condition. The grant-date fair value of awards that vest based on achievement of certain market conditions are determined using a Monte Carlo simulation technique. The grant-date fair value of awards that vest based on achievement of certain performance condition are determined using the accelerated attribution method once it is probable that the performance condition will be achieved.

Earnings Per Share

Earnings Per Share Basic earnings per common share is computed using the weighted average number of shares outstanding during the period. Diluted earnings per share is computed in a manner similar to the basic earnings per share, except that the weighted-average number of shares outstanding is increased to include all common shares, including those with the potential to be issued by virtue of options. Diluted earnings per share contemplate a complete conversion to common shares of all convertible instruments only if they are dilutive in nature with regards to earnings per share, as calculated under the treasury method.
