Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation, Principles of Consolidation and Use of Estimates The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”) and include the accounts of the Company and its wholly owned subsidiaries, Aurinia Pharma U.S., Inc., a Delaware corporation, and Aurinia Pharma Limited, a U.K. corporation. During 2024, Aurinia Pharma Limited was dissolved. All inter-company transactions and balances have been eliminated in consolidation. The preparation of the Company’s consolidated financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities in its consolidated financial statements and the accompanying notes. Actual results may differ materially from these estimates. Certain prior year amounts and notes to the consolidated financial statements have been reclassified to conform with the current year presentation. Taxes paid related to the net settlement of exercises of stock options and vesting of RSUs, which was previously included in proceeds from issuance of share-based awards on the consolidated statements of cash flows, have been separately presented for the years ended December 31, 2023 and 2022. Such reclassifications did not affect net income (loss), shareholders’ equity or cash flows. Summary of Significant Accounting Policies Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consist of operating accounts, money market funds and money market accounts. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Income generated from cash and cash equivalents is recorded as interest income. Cash is classified as restricted cash when certain funds are reserved for a specific purpose and are not available for immediate or general business use. Investments The Company invests its cash reserves in short-term, fixed rate, highly liquid financial instruments such as certificates of deposits and investments in U.S. treasury securities, U.S. government agency securities and highly rated corporate debt securities. The Company classifies its debt securities as available-for-sale in accordance with the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) Topic 320, Investments—Debt Securities . Investments classified as available-for-sale investments are carried at fair value. Unrealized gain (loss) is recorded in other comprehensive loss. Realized gain (loss) is recorded in interest income. The cost of securities sold is based on the specific-identification method. Interest income is accrued when earned and the amortization of premiums and accretion of discounts to maturity arising from acquisition is included in interest income on the consolidated statements of operations and comprehensive loss. Fair Value Measurements The Company's financial instruments consist primarily of cash and cash equivalents, investments, accounts receivable, accounts payable and accrued liabilities. The carrying value of accounts receivable, accounts payable and accrued expenses approximate their fair values because of their short-term nature. Estimated fair values of available-for-sale debt securities are generally based on prices obtained from commercial pricing services. FASB ASC Topic 820-10, Fair Value Measurements and Disclosures (“ASC 820-10”), defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets. Level 2: Inputs, other than the quoted prices in active markets that are observable either directly or indirectly. Level 3: Unobservable inputs for which there are little or no market data, which require the reporting entity to develop its own assumptions. See Note 4 for a summary of financial assets measured at fair value on a recurring basis. Accounts Receivable, Net Accounts receivables are stated as amounts due, net of estimates for discounts offered in customer contracts and any expected credit losses. The Company estimates expected credit losses using the “expected loss” model, which is based on an assessment of the collectability of customer accounts, including collection history, credit quality, the age of past-due balances, current conditions, and reasonable and supportable future conditions that might impact a customer’s ability to pay. The allowance for credit losses is periodically analyzed and adjusted as needed through a charge to selling, general and administrative expense. Amounts deemed to be uncollectible are charged against the allowance for credit losses. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between the transfer of the promised good to the customer and receipt of payment will be one year or less. As of December 31, 2024 and 2023, the Company did not record an allowance for credit losses. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, investments and accounts receivable. The Company maintains cash balances with a limited number of highly reputable financial institutions in excess of amounts insured by the Federal Deposit Insurance Corporation and Canada Deposit Insurance Corporation. The Company's investment policy limits the investment of excess cash to certain types of financial instruments such as certificates of deposit, money market instruments, U.S. treasury securities, U.S. government agency securities and highly rated corporate debt securities, and places restrictions on maturities and concentration by type and issuer. To date, the Company has not experienced any losses associated with credit risk and continues to believe that this exposure is not significant. The Company’s major customers, which includes two specialty pharmacies and its collaboration partner, Otsuka Pharmaceutical Co., Ltd (“Otsuka”) accounted for the majority of the Company's accounts receivable as of December 31, 2024. Net product sales from the two specialty pharmacies represent 88% of total revenues for the year ended December 31, 2024, compared to 91% for the same period in 2023. To avoid supply chain disruptions, the Company has provided a nominal additional discount to its two specialty pharmacies since March 2022. The Company monitors economic conditions and the creditworthiness of its customers. The Company regularly communicates with its customers regarding the status of receivable balances and has not experienced any issues with collectability. The timing between the recognition of revenue and the receipt of payment is not significant. The Company's standard credit terms range from 30 to 45 days. The Company has had no historical write-offs related to its customers or receivables. Inventory, Net Inventory is valued under a standard costing methodology on a first-in, first-out basis and is stated at the lower of cost or net realizable value. The Company determines whether to capitalize inventory costs for a product based on, among other factors, the status of regulatory approval and recoverability of costs. Capitalized costs of inventory mainly include third party manufacturing costs and allocated internal labor. Storage, transportation and insurance costs are immaterial and expensed in the period incurred. The Company assesses recoverability of inventory each reporting period and writes down inventory when inventory has become obsolete, has a cost basis in excess of its net realizable value or quantities are in excess of expected product sales. Intangible Assets, Net Intangible assets are amortized on a straight-line basis over the estimated useful life of the related assets. The Company evaluates the estimated remaining useful life of its intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. Acquired intellectual property or a reacquired right is initially recorded at cost. If the terms of the contract giving rise to a reacquired right are favorable relative to the terms of current market transactions for the same or similar items, the difference is recognized as a gain in the consolidated statements of operations and comprehensive loss. Acquired intellectual property and reacquired rights are amortized on a straight-line basis over periods ranging from 10 to 12 years. External patent costs associated with preparing, filing, obtaining and protecting patents are capitalized and amortized on a straight-line basis over the shorter of the estimated useful life or the patent life, commencing in the year of patent grant. Patents do not contain the option to extend or renew. External legal costs incurred to defend a patent are capitalized when it is believed that the future economic benefit of the patent will be increased and a successful defense is probable. Property and Equipment, Net Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the lease term or the estimated useful life of the related assets. Maintenance and repairs are charged to expense as incurred; however, maintenance and repairs that improve or extend the life of existing assets are capitalized. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any gain or loss is included in other (income) expense, net in the year of sale or disposal. Recoverability and Impairment of Long-lived Assets ASC Topic 360 requires long-lived assets, including definite-lived intangible assets, to be evaluated for impairment at least annually or when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced by the asset, including its eventual residual value, is compared to the carrying value to determine whether impairment exists. If such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values. Fair value is estimated through discounted cash flow models to project cash flows from the asset. For the years ended December 31, 2024, 2023, and 2022, the Company recognized no asset impairment charge. Leases The Company assesses all contracts at inception to determine whether a lease exists. The Company’s leases are classified either as operating or finance leases per ASC 842. The Company leases office space under operating leases that typically provide for the payment of minimum annual rentals and may include scheduled rent increases. The Company also entered into a manufacturing agreement that contained an embedded lease of a dedicated manufacturing facility (the “Monoplant”) that was accounted for as a finance lease when the lease commencement began (see Note 5). Leases with an initial term of 12 months or less are not recorded on the Company's consolidated balance sheets and those lease payments are recognized on a straight-line basis over the lease term in its consolidated statements of operations and comprehensive loss. For leases other than short-term leases, at lease commencement, the Company records a lease liability based on the present value of lease payments over the expected lease term. The Company calculates the present value of lease payments using the discount rate implicit in the lease, unless that rate cannot be readily determined. In that case, the Company uses its incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis an amount equal to the lease payments over the expected lease term. The Company records a corresponding right-of-use lease asset based on the lease liability, adjusted for any lease incentives received and any initial direct costs paid to the lessor prior to the lease commencement date. The Company elected to use the practical expedient that allows lessees to treat the lease and non-lease components of leases as a single lease component. After lease commencement, the Company measures its leases as follows: (i) the lease liability based on the present value of the remaining lease payments using the discount rate determined at lease commencement; and (ii) the right-of-use lease asset based on the remeasured lease liability, adjusted for any unamortized lease incentives received, any unamortized initial direct costs and the cumulative difference between rent expense and amounts paid under the lease agreement. Any lease incentives received and any initial direct costs are amortized on a straight-line basis over the expected lease term. Rent expense is recorded on a straight-line basis over the expected lease term. Deferred Compensation Arrangements The Company records deferred compensation arrangements as liabilities for estimated future employee benefits relating to certain employee retention arrangements. Pursuant to FASB ASC Topic 710, Compensation—General , the Company recognizes future benefits provided by employee retention arrangements, as deferred compensation, which is recognized when the Company determines that it is probable to make future payments. The present value of the deferred compensation liability is measured based on an income approach using an internal risk-adjusted net present value of the future payments to be made to participants and is based on the estimated future net revenue of voclosporin. Management uses significant judgement and estimates in determining the method, assumptions and inputs that are unobservable and inherently uncertain. Significant judgements and estimates include, but are not limited to, assumptions related to future net revenues of voclosporin and the risk-adjusted discount rate. The present value of the deferred compensation liability is remeasured at each balance sheet date and adjusted for changes in estimated cash flows. The impact of the remeasurement is recorded through gain (loss) on change in present value of the deferred compensation arrangements in other (income) expense, net. Common Shares The Company’s shares have no par value and, therefore, all amounts related to the issuance of common shares are recorded to common shares on the balance sheet. The value of common shares includes cash amounts received or paid for such shares and the fair value of equity awards and warrants. Amounts for common shares are offset by share issuance costs for equity offerings or transaction costs associated with share repurchases. Revenue Recognition Pursuant to FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue when a customer obtains control of promised goods or services. Revenue is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. To determine revenue recognition for contracts with customers within the scope of ASC 606, the Company performs the following 5 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) a performance obligation is satisfied. Net Product Sales The Company sells LUPKYNIS to two specialty pharmacies and a specialty distributor in the U.S., and the Company sells LUPKYNIS inventory to its collaboration partner, Otsuka for the European and Japanese market. The two specialty pharmacies, specialty distributor and Otsuka are considered the Company's customers for accounting purposes. Revenue from product sales is recognized when the customer obtains control of the Company's product, which typically occurs on delivery. Revenue from product sales is recorded at the transaction price, net of estimates for variable consideration consisting of prompt-pay discounts, customer fees, government rebates, co-payment assistance and payor rebates and administration fees for which reserves are established. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable (if the amount is payable to the customer) or a liability (if the amount is payable to a party other than the customer). Variable consideration is estimated using the expected-value amount method, which is the sum of probability-weighted amounts in a range of possible consideration amounts. In making these estimates, the Company considers historical data, including patient mix and inventory sold to customers that has not yet been dispensed. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary materially from the Company’s estimates, the Company will adjust these estimates, which will affect net product sales and earnings in the period such estimates are adjusted. These items include: • Prompt-Pay Discounts —The Company generally provides discounts on product sales to its customers for prompt payment. The Company estimates that its customers will earn these discounts and fees. These discounts and fees are recorded as a reduction of gross revenue and accounts receivable at the time such revenue is recognized. • Customer Fees —The Company pays certain customer fees, such as fees for certain data that customers provide to the Company. Customer fees paid to its customers are recorded as a reduction of gross revenue and accounts receivable, unless the payment is: (i) for a distinct good or service from the customer; and (ii) the Company can reasonably estimate the fair value of the goods or services received. If both conditions are met, the Company records the consideration paid to the customer as selling, general and administrative expense. • Government Rebates —The Company estimates government rebates, primarily Medicaid, based upon a range of possible outcomes for the estimated patient mix. Medicaid rebates relate to the Company's estimated obligations to states under reimbursement arrangements. Rebates are recorded as a reduction of gross revenue and a current liability is established and included in accrued expenses at the time such gross revenue is recognized. The amount of the rebate for each unit of product reimbursed by the state Medicaid program is established by law and is adjusted upward if the wholesale acquisition cost increases more than inflation (measured by the Consumer Price Index).The liability for Medicaid rebates consists of: (i) estimated current quarter claims; (ii) estimated prior quarter claims for which an invoice has not been received; (iii) prior quarter claims based on unpaid invoices received; and (iv) estimated claims for inventory in the distribution channel at period end. • Co-payment Assistance —Co-payment assistance represents financial assistance to qualified patients, assisting them with prescription drug co-payments required by insurance. The program is administered by the specialty pharmacies on the Company's behalf. Co-payment assistance is recorded as a reduction of revenue and a current liability is established and included in accrued expenses at the time such revenue is recognized. • Payor Rebates and Administration Fees —Payor rebates and administration fees represent the estimated obligations to third parties, primarily benefit managers. The payor rebates and administration fees result from formulary position, price increase limit allowances (price protection) and administration fees. The liability payor rebates and administration fees are based on the estimated payors buying patterns and the resulting applicable contractual rebate rate(s) to be earned over a contractual period. Payor rebates and administration fees are recorded as a reduction of revenue and a liability is established and included in accrued expenses at the time such revenue is recognized. Additionally, the Company has agreements with its partners that include options related to the promise for future supply of drug substance, semi-finished goods or drug product for either clinical development or commercial supply at the licensee’s discretion. The Company assesses if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations. If the Company is entitled to additional payments when the licensee exercises these options, any additional payments are recorded as product sales when the licensee obtains control of the goods, which is typically upon delivery. Certain agreements include terms where the Company can partially bill for drug substance used before the manufacturing cycle is complete, resulting in a deferred revenue which is to be recognized once delivery occurs. License, Collaboration and Royalty Revenue The Company enters into out-license agreements with counterparties to develop and commercialize LUPKYNIS in certain ex-U.S. territories in exchange for: (i) upfront cash payments; (ii) regulatory and commercial milestone payments; (iii) sales-based royalties; and (iv) payments for manufacturing and other services the Company provides. Each of these payments results in license, collaboration and royalty revenue. Licenses If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other performance obligations, management uses judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. Milestones At the inception of each arrangement that includes commercial sales milestone payments, the Company evaluates whether achieving each milestone payment is considered probable and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the value of the associated milestone is included in the transaction price. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and royalty revenue in the period of adjustment. Sales-based milestone payments are recognized in the period that the milestone objectives have been achieved. Royalties For arrangements that include sales-based royalties, revenue is recognized when the underlying product sales have occurred. Revenue is recorded based on estimated quarterly net sales reports provided by its partner. Differences between actual results and estimated amounts are adjusted in the period in which they become known, which typically follows the quarterly period in which the estimate is made. Manufacturing and Other Services The Company’s agreements may include manufacturing or other services to be performed by the Company on behalf of the counterparty. If these services are determined to be distinct from the other promises or performance obligations identified in the arrangement, the Company recognizes the transaction price allocated to these services as revenue. The revenue is recognized either: (i) over time based on an appropriate measure of progress when the performance by the Company does not create an asset with an alternative use and the Company has an enforceable right to payment for the performance completed to date; (ii) or at a point in time as the related performance obligations are satisfied. Certain agreements may include terms where the Company can partially bill for manufacturing services before the serves are provided, resulting in a deferred revenue which is to be recognized once the performance obligation is satisfied. Cost of Revenue Cost of revenue consists primarily of the cost of inventory for LUPKYNIS and semi-finished product, which mainly includes third-party manufacturing costs and allocated internal labor. Cost of revenue also includes costs related to collaboration revenues and the amortization of the finance right-of-use asset recognized in connection with the Monoplant. Selling, General and Administrative (“SG&A”) Expense Selling, general and administrative (“SG&A”) expense consists of personnel and non-personnel expenses to support growing sales of LUPKYNIS. Personnel-related expense includes salaries, incentive pay, benefits and share-based compensation for personnel engaged in sales, finance and administrative functions. As the majority of the Company's contracts are short-term in nature, sales commissions are generally recorded as selling, general and administrative expense when incurred as the amortization period would have been less than one year. Non-personnel-related expense includes: (i) selling, patient services, pharmacovigilance, marketing, advertising, travel, sponsorships and trade shows; and (ii) other general and administrative costs, including consulting, legal, patent, insurance, accounting, information technology and facilities. SG&A expenses are recognized as they are incurred. The Company uses a third-party logistics provider to perform a full order-to-cash service, which includes warehousing and shipping directly to its two specialty pharmacies and receiving orders from a specialty distributor for shipping to hospitals on their behalf. Since these costs are not integral to bringing the inventories to a salable condition, the Company elected not to treat shipping and handling costs as a fulfillment activity. Shipping and handling costs related to order fulfillment are recorded in SG&A expenses. Research and Development (“R&D”) Expense Research and development (“R&D”) expense consists of personnel and non-personnel expenses. Personnel-related expense includes salaries, incentive pay, benefits and share-based compensation for personnel engaged in research and development functions. Non-personnel-related expense includes subcontractors and materials used for R&D activities, development, clinical trials, clinical supply and distribution, and other professional services. R&D expenses are recognized as they are incurred based on actual work completed through monitoring invoices received and discussions with internal personnel and external service providers as to the progress or stage of completion of the clinical studies and the agreed-upon fee to be paid for such services. Where contingent milestone payments are due to third parties under R&D arrangements or license agreements, the milestone payment obligations are expensed when the milestone results are probable to be achieved. Restructuring Expense Restructuring expenses consist primarily of one-time termination benefits, including severance and healthcare benefits, contract terminations and other costs. According to ASC 420, Exit or Disposal Cost Obligations (“ASC 420”), restructuring expense is measured at fair value and recognized as a liability when incurred. One-time termination benefits are expensed on the date on which the Company notifies the affected employees of the restructuring plan, unless employees must provide future service, in which case the expense is recognized over the service period. Shared-based Compensation Expense The Company follows ASC Topic 718, Compensation - Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards made to employees and directors. The Company records compensation expense based on the fair value on the grant date using the graded accelerated vesting method for all share-based payments related to stock options, performance awards (“PAs”), restricted stock units (“RSUs”) and purchases under the Company's 2021 Employee Stock Purchase Plan. The estimated fair value of PAs is measured on the grant date and is recognized when it is determined that it is probable that the performance condition will be achieved. The Company has elected a policy for all share-based awards to estimate forfeitures based on historical forfeiture experience at the time of grant and revise in subsequent periods if actual forfeitures differ from those estimates. Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the income tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. A valuation allowance is applied against any deferred tax asset if, based on available evidence, it is “more likely than not” that some or all of the deferred tax assets will not be realized. For uncertain tax positions that meet a “more likely than not” threshold, the Company recognizes the benefit of uncertain tax positions in the consolidated financial statements. The Company’s practice is to recognize interest and penalties, if any, related to uncertain tax positions in its provision for income taxes in the consolidated statements of operations. Foreign Currency The functional currency and reporting currency for the Company and all of its foreign subsidiaries is determined to be the U.S. dollar. Thus, the Company does not record cumulative translations adjustment upon consolidation. All monetary assets and liabilities denominated in a foreign currency are remeasured into U.S. dollars at the exchange rate on the balance sheet date. Non-monetary assets and liabilities (along with their related expenses) are translated at the rate of exchange in effect on the date assets were acquired. Monetary income and expense items are translated at the average foreign exchange rate for the period. Foreign exchange gains and losses arising on translation or settlement of a foreign currency denominated monetary item are included in the consolidated statements of operations and comprehensive loss in other (income) expense, net. For the years ended December 31, 2024, 2023, and 2022, the Company recognized $(5.9) million, $5.9 million and nil of foreign exchange gain (loss) related to the revaluation of its finance lease liability |
