1. Description of Business and Basis of Presentation Organization Aridis Pharmaceuticals, Inc. (the “Company” or “we” or “our” or “us”) was established as a California limited liability corporation in 2003. The Company converted to a Delaware C corporation on May 21, 2014. Our principal place of business is in Los Gatos, California. We are a late-stage biopharmaceutical company focused on developing new breakthrough therapies for infectious diseases and addressing the growing problem of antibiotic resistance. The Company has a deep, diversified portfolio of clinical and pre-clinical stage non-antibiotic anti-infective product candidates that are complemented by a fully human monoclonal antibody discovery platform technology. The Company’s suite of anti-infective monoclonal antibodies offers opportunities to profoundly alter the current trajectory of increasing antibiotic resistance and improve the health outcome of many of the most serious life-threatening infections particularly in hospital settings. Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements include the amounts of the Company and our wholly owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and applicable rules of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the preceding fiscal year included in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (“SEC”) on May 22, 2023. The condensed consolidated financial statements include the accounts of the Company and its two wholly-owned subsidiaries, Aridis Biopharmaceuticals, LLC and Aridis Pharmaceuticals, C.V. All intercompany balances and transactions have been eliminated in consolidation. The Company operates in one segment. Management uses one measurement of profitability and does not segregate its business for internal reporting. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period. The accompanying condensed consolidated balance sheet at September 30, 2023 has been derived from the audited balance sheet at December 31, 2022 contained in the above referenced Form 10-K. Going Concern The Company has had recurring losses from operations since inception and had negative cash flows from operating activities during the nine months ended September 30, 2023, and the year ended December 31, 2022. Management expects to incur operating losses and negative cash flows from operations in the foreseeable future as the Company continues its product development programs. The forecasted outflow of cash for at least a one-year period from the expected condensed consolidated financial statement issuance date is in excess of the cash available on-hand. The Company’s research and development expenses and resulting cash burn during the nine months ended September 30, 2023, were largely due to costs associated with the Phase 1/2 study of AR-501 for the treatment of chronic lung infections associated with cystic fibrosis and the activities associated with the Phase 3 study of AR-320 for the prevention of S. aureus VAP. Until the clinical development activities for AR-301 and AR-320 resume, the current clinical development activities are focused primarily on AR-501. The Company plans to fund its cash flow needs through future debt and/or equity financings, which we may obtain through one or more public or private equity offerings, debt financings, government or other third-party funding, strategic alliances and licensing or collaboration arrangements. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs or future commercialization efforts, which could adversely affect its future business prospects and its ability to continue as a going concern. The Company believes that its current available cash and cash equivalents, including cash received in August 2023 from equity raise proceeds, will not be sufficient to fund its planned expenditures and meet the Company’s obligations for at least the one-year period following its consolidated financial statement issuance date. In the absence of equity or debt financing, or other capital sources, including grant funding, potential collaborations or other strategic transactions, management anticipates that existing cash resources will not be sufficient to meet operating and liquidity needs on or before November 30, 2023. The accompanying condensed consolidated financial statements have been prepared on a going concern basis that contemplates the realization of assets and discharge of liabilities in their normal course of business. There is substantial doubt about the Company’s ability to continue as a going concern for one year after the date that these condensed consolidated financial statements are issued. These condensed consolidated financial statements do not include any adjustments that might be necessary from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Such estimates include those related to the evaluation of our ability to continue as a going concern, best estimate of standalone selling price of revenue deliverables, useful life of long-lived assets, classification of deferred revenue, income taxes, assumptions used in the Black-Scholes-Merton (“BSM”) model to calculate the fair value of stock-based compensation, deferred tax asset valuation allowances, and preclinical study and clinical trial accruals.

The Company considers the creditworthiness of its customers but does not require collateral in advance of a sale. The Company evaluates collectability and maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio when necessary. The allowance is based on the Company’s best estimate of the amount of losses in the Company’s existing accounts receivable, which is based on customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of September 30, 2023, and December 31, 2022, there were $0.4 million and $1.0 million in accounts receivable, respectively, and no allowances for doubtful accounts. Operating Leases The Company determines if an arrangement is or contains a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and include any lease payments made prior to or on lease commencement and lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is generally unknown, the Company used its incremental borrowing rate of 6% based on the information available at the lease commencement date in determining the present value of future lease payments. Lease costs for the Company’s operating leases are recognized on a straight-line basis within operating expenses over the reasonably assured lease term. The Company has elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for any lease and non-lease components as a single lease component. Prior to adoption of ASC 842, Leases as of January 1, 2022, the Company evaluated leases at their inception as either operating or capital leases, and renewal or expansion options, rent holidays, leasehold improvement allowances and other incentives on such lease agreements. The Company recognized operating lease costs on a straight-line basis over the term of the agreement. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, generally between three and five years for lab equipment and computer equipment and software, and over the shorter of the lease term or useful life for leasehold improvements. Maintenance and repairs are charged to expense as incurred, and costs of improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the condensed consolidated balance sheet and any resulting gain or loss is reflected in the condensed consolidated statement of operations in the period realized. Intangible Assets Intangible assets are recorded at cost and amortized over the estimated useful life of the asset. Intangible assets consist of licenses with various institutions whereby the Company has rights to use intangible property obtained from such institutions. Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future undiscounted net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment is measured by the excess of the carrying amount of the assets over fair value less the costs to sell the assets, generally determined using the projected discounted future net cash flows arising from the asset. There have been no such impairments of long-lived assets during the period ended September 30, 2023 and approximately $227 thousand in impairment of lab equipment during the period ended December 31, 2022. Revenue Recognition The Company recognizes revenue based on Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), which applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. See Note 6 for details of the development and license agreements. To determine revenue recognition for arrangements that the Company determines are within the scope of 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 at a point in time, or over time, as the entity satisfies performance obligations. The Company only applies the five-step model to contracts when it is probable that it 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, 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. As part of the accounting for customer arrangements, the Company must use judgment to determine: a) the number of performance obligations based on the determination under step (ii) above; b) the transaction price under step (iii) above; and c) the standalone selling price for each performance obligation identified in the contract for the allocation of the transaction price in step (iv) above. The Company uses judgment to determine whether milestones or other variable consideration should be included in the transaction price. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. In developing the standalone price for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs. The Company recognizes revenue as or when the performance obligations under the contract are satisfied. The Company receives grant and license payments from its customers based on payment schedules established in each contract. The Company records any amounts received prior to satisfying the revenue recognition criteria as deferred revenue on its condensed consolidated balance sheets. Amounts recognized as revenue, but not yet received or invoiced are recorded within other receivables on the condensed consolidated balance sheet. Amounts are recorded as other receivables on the condensed consolidated balance sheet when our right to consideration is unconditional. 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 payment by the customer and the transfer of a majority of the promised goods or services to the customer will be one year or less. Contract Assets The incremental costs of obtaining a contract under ASC 606 (i.e., costs that would not have been incurred if the contract had not been obtained) are recognized as an asset in the Company’s condensed consolidated balance sheets if the Company expects to recover them (see Note 6). Capitalized costs will be amortized to the respective expenses using a systematic basis that mirrors the pattern in which the Company transfers control of the goods and service to the customer. At each reporting date, the Company determines whether the capitalized costs to obtain a contract are impaired by comparing the carrying amount of the asset to the remaining amount of consideration that the Company received and expects to receive less the costs that relate to providing services under the relevant contract. Capitalized contract assets were $0 at September 30, 2023 and $2.1 million at December 31, 2022. Amortization of the contract assets was $0 for the three and nine month periods ended September 30, 2023, and $0 for the three and nine month periods ended September 30, 2022. In connection with the termination of a license agreement, $0 and $2.1 million of contract assets were impaired for the three and nine month periods ended September 30, 2023, respectively. Contract Liabilities Amounts received prior to satisfying the above revenue recognition criteria, or in which the Company has an unconditional right to payment, are recorded as deferred revenue in the Company’s condensed consolidated balance sheets. The Company has estimated the classification between current and noncurrent deferred revenue related to the respective license agreement within its condensed consolidated balance sheets at September 30, 2023, and December 31, 2022 (see Note 6). Research and Development Research and development costs are expensed to operations as incurred.

Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and capitalized. The capitalized amounts are then expensed as the related goods are delivered or when the services are performed. Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards based on the grant-date estimated fair values, which the Company determines using the BSM option pricing model, on a straight-line basis over the requisite service period for the award. The Company accounts for forfeitures as they occur. The BSM option pricing model incorporates various highly sensitive assumptions, including the fair value of our common stock, expected volatility, expected term and risk-free interest rates. The weighted average expected life of options was calculated using the simplified method as prescribed by the SEC’s Staff Accounting Bulletin, Topic 14 (“SAB Topic 14”). This decision was based on the lack of relevant historical data due to our limited historical experience. In addition, due to our limited historical data, the estimated volatility also reflects the application of SAB Topic 14, incorporating the historical volatility of comparable companies whose stock prices are publicly available. The risk-free interest rate for the periods within the expected term of the option is based on the U.S. Treasury yield in effect at the time of grant. The dividend yield was zero, as we have never declared or paid dividends and have no plans to do so in the foreseeable future. Income Taxes The Company accounts for income taxes under the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by the relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. At each balance sheet date, unresolved uncertain tax positions must be reassessed, and the Company will determine whether (i) the factors underlying the sustainability assertion have changed and (ii) the amount of the recognized benefit is still appropriate. The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes available. The Company’s policy is to recognize interest or penalties related to income tax matters in income tax expense. Other Comprehensive Income Other comprehensive income is derived from the change in credit risk calculated by our fair value option valuation in connection with the Note Purchase Agreements with Streeterville Capital, LLC. Accumulated other comprehensive income increased from $5.1 million at December 31, 2022 to $7.8 million at September 30, 2023. Earnings (Net Loss) Per Share Basic earnings (net loss) per share is calculated by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net earnings (net loss) per share is computed by dividing the net income (loss) by the weighted-average number of common shares and potentially dilutive securities outstanding for the period. For the three and nine months ended September 30, 2023 the number of shares used to compute basic earnings (net loss) per share were <span id="xdx_90C_eus-gaap--WeightedAverageNumberOfSharesOutstandingBasic_pn5n6_c20230701__20230930_zOSxytt6uZEl" title="Weighted-average common shares outstanding used in computing net loss per share available to common stockholders, basic">37.4 million shares and <span id="xdx_900_eus-gaap--WeightedAverageNumberOfSharesOutstandingBasic_pn5n6_c20230101__20230930_z3xYil26WYN3" title="Weighted-average common shares outstanding used in computing net loss per share available to common stockholders, basic">35.6 million shares, respectively.

JOBS Act Accounting Election The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We are choosing to take advantage of this provision and, as a result, we will adopt the extended transition period available under the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided under the JOBS Act. New Accounting Pronouncements ASU 2016-02 - Accounting for Lease Obligation (“ASU 2016-02”) In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (Topic 842). This guidance requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 establishes a right-of-use model (ROU) that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this standard effective January 1, 2022, as required, retrospectively through a cumulative effect adjustment. The new standard provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permits the Company not to reassess, under ASU 2016-02, prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected to utilize the short-term lease recognition exemption for all leases that qualify. This means, for those short-term leases that qualify, the Company will not recognize ROU assets or lease liabilities. The Company also elected to separate lease and non-lease components for facility leases. Adoption of this guidance resulted in the recognition of lease liabilities of $2.3 million, based on the present value of the remaining minimum rental payments under current leasing standards for the Company’s applicable existing office space operating lease, with corresponding ROU assets of $1.9 million as of adoption date on January 1, 2022.

Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Such estimates include those related to the evaluation of our ability to continue as a going concern, best estimate of standalone selling price of revenue deliverables, useful life of long-lived assets, classification of deferred revenue, income taxes, assumptions used in the Black-Scholes-Merton (“BSM”) model to calculate the fair value of stock-based compensation, deferred tax asset valuation allowances, and preclinical study and clinical trial accruals. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of checking account and money market fund account balances. Restricted cash consists of deposits for a letter of credit that the Company has provided to secure its obligations under its facility lease as well as grant funds identified for the specific grant project.

Accounts Receivable and Allowance for Doubtful Accounts Accounts receivables are recorded at the invoiced amount and do not bear interest. The Company considers the creditworthiness of its customers but does not require collateral in advance of a sale. The Company evaluates collectability and maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio when necessary. The allowance is based on the Company’s best estimate of the amount of losses in the Company’s existing accounts receivable, which is based on customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of September 30, 2023, and December 31, 2022, there were $0.4 million and $1.0 million in accounts receivable, respectively, and no allowances for doubtful accounts.

Operating Leases The Company determines if an arrangement is or contains a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and include any lease payments made prior to or on lease commencement and lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is generally unknown, the Company used its incremental borrowing rate of 6% based on the information available at the lease commencement date in determining the present value of future lease payments. Lease costs for the Company’s operating leases are recognized on a straight-line basis within operating expenses over the reasonably assured lease term. The Company has elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for any lease and non-lease components as a single lease component. Prior to adoption of ASC 842, Leases as of January 1, 2022, the Company evaluated leases at their inception as either operating or capital leases, and renewal or expansion options, rent holidays, leasehold improvement allowances and other incentives on such lease agreements. The Company recognized operating lease costs on a straight-line basis over the term of the agreement. 0.06

Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, generally between three and five years for lab equipment and computer equipment and software, and over the shorter of the lease term or useful life for leasehold improvements. Maintenance and repairs are charged to expense as incurred, and costs of improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the condensed consolidated balance sheet and any resulting gain or loss is reflected in the condensed consolidated statement of operations in the period realized.

P5Y

Intangible Assets Intangible assets are recorded at cost and amortized over the estimated useful life of the asset. Intangible assets consist of licenses with various institutions whereby the Company has rights to use intangible property obtained from such institutions.

Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future undiscounted net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment is measured by the excess of the carrying amount of the assets over fair value less the costs to sell the assets, generally determined using the projected discounted future net cash flows arising from the asset. There have been no such impairments of long-lived assets during the period ended September 30, 2023 and approximately $227 thousand in impairment of lab equipment during the period ended December 31, 2022.

Revenue Recognition The Company recognizes revenue based on Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”), which applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. See Note 6 for details of the development and license agreements. To determine revenue recognition for arrangements that the Company determines are within the scope of 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 at a point in time, or over time, as the entity satisfies performance obligations. The Company only applies the five-step model to contracts when it is probable that it 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, 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. As part of the accounting for customer arrangements, the Company must use judgment to determine: a) the number of performance obligations based on the determination under step (ii) above; b) the transaction price under step (iii) above; and c) the standalone selling price for each performance obligation identified in the contract for the allocation of the transaction price in step (iv) above. The Company uses judgment to determine whether milestones or other variable consideration should be included in the transaction price. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. In developing the standalone price for a performance obligation, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs. The Company recognizes revenue as or when the performance obligations under the contract are satisfied. The Company receives grant and license payments from its customers based on payment schedules established in each contract. The Company records any amounts received prior to satisfying the revenue recognition criteria as deferred revenue on its condensed consolidated balance sheets. Amounts recognized as revenue, but not yet received or invoiced are recorded within other receivables on the condensed consolidated balance sheet. Amounts are recorded as other receivables on the condensed consolidated balance sheet when our right to consideration is unconditional. 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 payment by the customer and the transfer of a majority of the promised goods or services to the customer will be one year or less. Contract Assets The incremental costs of obtaining a contract under ASC 606 (i.e., costs that would not have been incurred if the contract had not been obtained) are recognized as an asset in the Company’s condensed consolidated balance sheets if the Company expects to recover them (see Note 6). Capitalized costs will be amortized to the respective expenses using a systematic basis that mirrors the pattern in which the Company transfers control of the goods and service to the customer. At each reporting date, the Company determines whether the capitalized costs to obtain a contract are impaired by comparing the carrying amount of the asset to the remaining amount of consideration that the Company received and expects to receive less the costs that relate to providing services under the relevant contract. Capitalized contract assets were $0 at September 30, 2023 and $2.1 million at December 31, 2022. Amortization of the contract assets was $0 for the three and nine month periods ended September 30, 2023, and $0 for the three and nine month periods ended September 30, 2022. In connection with the termination of a license agreement, $0 and $2.1 million of contract assets were impaired for the three and nine month periods ended September 30, 2023, respectively. Contract Liabilities Amounts received prior to satisfying the above revenue recognition criteria, or in which the Company has an unconditional right to payment, are recorded as deferred revenue in the Company’s condensed consolidated balance sheets. The Company has estimated the classification between current and noncurrent deferred revenue related to the respective license agreement within its condensed consolidated balance sheets at September 30, 2023, and December 31, 2022 (see Note 6).

Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and capitalized. The capitalized amounts are then expensed as the related goods are delivered or when the services are performed.

Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards based on the grant-date estimated fair values, which the Company determines using the BSM option pricing model, on a straight-line basis over the requisite service period for the award. The Company accounts for forfeitures as they occur. The BSM option pricing model incorporates various highly sensitive assumptions, including the fair value of our common stock, expected volatility, expected term and risk-free interest rates. The weighted average expected life of options was calculated using the simplified method as prescribed by the SEC’s Staff Accounting Bulletin, Topic 14 (“SAB Topic 14”). This decision was based on the lack of relevant historical data due to our limited historical experience. In addition, due to our limited historical data, the estimated volatility also reflects the application of SAB Topic 14, incorporating the historical volatility of comparable companies whose stock prices are publicly available. The risk-free interest rate for the periods within the expected term of the option is based on the U.S. Treasury yield in effect at the time of grant. The dividend yield was zero, as we have never declared or paid dividends and have no plans to do so in the foreseeable future.

Income Taxes The Company accounts for income taxes under the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized. The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax years that are still subject to assessment or challenge by the relevant taxing authorities. Assessing an uncertain tax position begins with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. At each balance sheet date, unresolved uncertain tax positions must be reassessed, and the Company will determine whether (i) the factors underlying the sustainability assertion have changed and (ii) the amount of the recognized benefit is still appropriate. The recognition and measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes available. The Company’s policy is to recognize interest or penalties related to income tax matters in income tax expense.

Earnings (Net Loss) Per Share Basic earnings (net loss) per share is calculated by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net earnings (net loss) per share is computed by dividing the net income (loss) by the weighted-average number of common shares and potentially dilutive securities outstanding for the period. For the three and nine months ended September 30, 2023 the number of shares used to compute basic earnings (net loss) per share were <span id="xdx_90C_eus-gaap--WeightedAverageNumberOfSharesOutstandingBasic_pn5n6_c20230701__20230930_zOSxytt6uZEl" title="Weighted-average common shares outstanding used in computing net loss per share available to common stockholders, basic">37.4 million shares and <span id="xdx_900_eus-gaap--WeightedAverageNumberOfSharesOutstandingBasic_pn5n6_c20230101__20230930_z3xYil26WYN3" title="Weighted-average common shares outstanding used in computing net loss per share available to common stockholders, basic">35.6 million shares, respectively.

JOBS Act Accounting Election The JOBS Act permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We are choosing to take advantage of this provision and, as a result, we will adopt the extended transition period available under the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided under the JOBS Act.

New Accounting Pronouncements ASU 2016-02 - Accounting for Lease Obligation (“ASU 2016-02”) In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (Topic 842). This guidance requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 establishes a right-of-use model (ROU) that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted this standard effective January 1, 2022, as required, retrospectively through a cumulative effect adjustment. The new standard provides a number of optional practical expedients in transition. The Company elected the “package of practical expedients,” which permits the Company not to reassess, under ASU 2016-02, prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected to utilize the short-term lease recognition exemption for all leases that qualify. This means, for those short-term leases that qualify, the Company will not recognize ROU assets or lease liabilities. The Company also elected to separate lease and non-lease components for facility leases. Adoption of this guidance resulted in the recognition of lease liabilities of $2.3 million, based on the present value of the remaining minimum rental payments under current leasing standards for the Company’s applicable existing office space operating lease, with corresponding ROU assets of $1.9 million as of adoption date on January 1, 2022.

3. Fair Value Disclosure Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability 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 fair value hierarchy defines a three-level valuation hierarchy for disclosure of fair value measurements as follows: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif;

The Company accounted for its investment in the JV Entity as an equity method investment.

The project has 46 participants including European Federation of Pharmaceutical Industries and Associations (EFPIA) companies, universities, research organizations, public bodies, non-profit groups, subject matter experts, and third parties. The Company’s primary role in the project is to help lead a Phase 3, randomized, double-blind, placebo-controlled trial to evaluate efficacy of suvratoxumab in the prevention of S. aureus Ventilator Associated Pneumonia (VAP) in mechanically ventilated Intensive Care Unit (ICU) patients. We are acting as study sponsor for Phase 3 clinical study to be conducted and assume responsibility for ensuring that all studies are conducted according to International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. This study will be conducted in approximately 200 sites distributed globally across European Union (EU) and non-EU sites (50% EU and 50% non-EU). To help facilitate these trials, we make in-kind contributions of materials and services to the project at non-EU sites. The academic COMBACTE-NET consortium partners initially pay for all costs incurred at EU clinical sites and subsequently bills the Company for 25% of such costs. Specifically, we are billed for 25% of eligible costs during the entire fiscal year six to seven months following the fiscal year. The work at these sites is performed entirely by third-party subcontractors. As such, we reimburse the 25% at the passed-through invoice amounts. There is no reimbursement for costs incurred at non-EU sites. After October 31, 2023, the Company is committed to continuing the trials whether or not a renewal is executed with the IMI JU. If no renewal is executed, the trials will continue without any form of reimbursement. Under the IMI JU Agreement, the Company will own all results, findings, and intellectual property generated by the project and is entitled to receive any benefits these items bring. As such, these costs are deemed research and development expenditures. Considering our obligation to repay a portion of costs incurred, we determined this agreement is under the scope of ASC Subtopic 730-20, Research and Development Arrangements. Further, as the parties in the IMI JU Agreement are active participants and are exposed to significant risks and rewards dependent on the commercial success of the research, this agreement is also under the scope of ASC Topic 808, Collaborative Arrangements. Research and development costs incurred at non-EU sites are recognized as incurred. The Company recognized research and development expenses of $0.7 and $1.4 million for the three and nine months ended September 30, 2023, respectively, and approximately $5.5 million for the year ended December 31, 2022 at non-EU sites. Research and development costs incurred at EU sites are recognized as incurred for 25% of these costs. Research and development expenses of approximately $0 and $2.3 million were incurred at EU sites for the three and nine months ended September 30, 2023, respectively, and approximately $3.8 million for the year ended December 31, 2022. Of this gross expense amount, the EU contributed services of 75%, or $0 and $1.7 million for the three and nine months ended September 30, 2023, respectively, and $2.9 million for the year ended December 31, 2022. Thus, our liability presented on the accompanying condensed consolidated balance sheet is $0.6 million as of September 30, 2023 and $1.0 million as of December 31, 2022, and are presented within Accrued Liabilities on the accompanying condensed consolidated balance sheets. In-kind contributions we make to the program will be expensed as R&D at their fair value when made. If the fair value of an in-kind contribution we make to the IMI JU differs from its carrying amount, we will recognize a gain or loss on disposition. No gain or loss on disposition was recognized for the three and nine month periods ended September 30, 2023. Cystic Fibrosis Foundation Development Agreement In December 2016, the Company received an award from the Cystic Fibrosis Foundation (“CFF”), which was executed under the Development Program Letter Agreement (the “CFF Agreement”), for approximately $2.9 million. Under the CFF Agreement, CFF made an upfront payment of $<span id="xdx_905_ecustom--AwardUpfrontPaymentReceived_c20161201__20161231__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember_zmPI5ADpARP7" title="Award, upfront payment received">200,000 and will make milestone payments to the Company as certain milestones defined in the agreement are met. The milestones relate to pre-clinical and clinical research activities. The agreement also specifies that we are obligated to cumulatively spend on the development program at least an equal amount that the Company receives from the CFF. In the event that we do not spend as much as we received under the agreement, we are obligated to return any overage to the CFF. In November 2018, the CFF increased the award to approximately $7.5 million. In December 2022, the CFF further increased the award to approximately $7.6 million by adding the “Additional Award Amount” of $<span id="xdx_90D_ecustom--AdditionalAwardAmount_c20221201__20221231__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember_zaxJvHyL9Z5b" title="Additional amount of award">150,000 with amendment no 2. As of the adoption date of ASC 606 on January 1, 2019 (the “Adoption Date”), the Company identified the following promises with regards to the clinical research activities under the CFF Agreement that represent an initial contract of: a) Phase 1 single ascending dose (“SAD”) clinical trial, which consists of the satisfied development-based milestones and one development-based milestone in progress which was accounted for as a single performance obligation; and contingent promises of: b) Phase 1 multiple ascending dose (“MAD”) clinical trial, which consists of one development-based milestone that had not yet been started, and c) Phase 2a clinical trial, which consists of four development-based milestones that had not yet been started. Of these promises, the Phase 1 SAD clinical trial was determined to be a distinct performance obligation as of the Adoption Date. For the clinical research activities related to the Phase 1 MAD clinical trial and the Phase 2a clinical trial that had not yet been started, the Company was contingently obligated to perform these clinical research activities only after the previous milestones, which achievement was uncertain, had been met. The Company determined that the consideration for the Phase 1 SAD clinical trial contract included several development-based milestones, which had been achieved as of the Adoption Date, totaling approximately $<span id="xdx_904_ecustom--ProbableTransactionPricePerformanceObligations_iI_pn5n6_c20190331__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--SeveralDevelopmentBasedMilestonesMember_zotlgviTkTXh" title="Probable transaction price performance obligations">1.7 million, and the one development-based milestone in progress as of the Adoption Date of $<span id="xdx_90D_ecustom--AmountOfProbableRevenueRemainingPerformanceObligationVariableConsideration_iI_pn5n6_c20190331__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--OneDevelopmentBasedMilestoneInProgressMember_zbeZIXKZur27" title="Amount of probable variable consideration">1.0 million became probable during the quarter ended March 31, 2019. Additionally, the Company determined the consideration for the Phase 1 MAD clinical trial contract included one development-based milestone of $<span id="xdx_90B_ecustom--AmountOfAchievedVariableConsideration_iI_pn5n6_c20200630__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--OneDevelopmentBasedMilestoneInProgressMember_zFu2n2XjQkE8" title="Amount of probable variable consideration">1.0 million which was achieved during the quarter ended June 30, 2020.

With the increased grant funding in December 2022, bringing the Phase 2a clinical trial contract total to approximately $<span id="xdx_904_ecustom--AmountOfTotalVariableConsideration_pn5n6_c20220101__20221231__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--FourDevelpomentBasedMilestonesMember_z77sBhNS4CO8" title="Amount of total variable consideration">3.9 million, CFF introduced an additional development-based milestone. The Company determined the consideration for the Phase 2a clinical trial contract totals approximately $<span id="xdx_90A_ecustom--AmountOfVariableConsideration_pn5n6_c20230101__20230930__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--FourDevelpomentBasedMilestonesMember_zgFvUfPgb66g" title="Amount of variable consideration">3.8 million which includes four development-based milestones. The milestones under the CFF Agreement are related to pre-clinical and clinical research activities and the realization of or recognition of revenue associated with the milestones as determined by the completion of the milestones and, if applicable, review and approval of the achievement by the CFF. Each development-based milestone payment has specific criteria that needs to be met, some examples of which include, the completion of certain study activities and approval to move to the next activity. At every reporting period, the Company evaluates the individual facts and circumstances of the development-based milestone to assess whether the revenue attributable to the development-based milestone in progress should be constrained. The constraint assessment by the Company includes an analysis of the key judgements and considerations used for each milestone which include, but are not limited to, the nature and amount of work to be performed, if the work is subject to the approval of the CFF, clinical data and uncertainty with regards to the results of the clinical studies, and the probability of successful clinical studies. The constraint will be removed once the Company achieves the development-based milestone or has determined that there is probable completion of the development-based milestone, and it has also concluded that it is not probable that revenue recognized attributable to the development-based milestone will result in a significant reversal of revenue in the future. The Company determined that the clinical research activities under the CFF Agreement should be recognized over time by calculating the amount of revenue to recognize in any given period by accumulating the total related costs incurred for the respective clinical research activities related to that distinct performance obligation using the input method (cost-to-cost) and applies that percentage of completion to the transaction price at each reporting period. The Company believes this method best depicts the transfer of control to the customer, which occurs as the costs related to the clinical research activities are incurred. The Company determined that as of September 30, 2023, the transaction price for the Phase 2a clinical trial contract was $<span id="xdx_906_ecustom--AmountOfVariableConsideration_pn5n6_c20230101__20230930__us-gaap--TypeOfArrangementAxis__custom--CysticFibrosisFoundationDevelopmentAgreementMember__us-gaap--AwardTypeAxis__custom--ThreeDevelpomentBasedMilestonesMember_zhgJUTG7U3Y3" title="Amount of variable consideration">3.6 million based on the achievement of the three development-based milestones during the year ended December 31, 2022 and completion of the fourth milestone during the quarter ended September 30, 2023.

Gates Foundation Grant Agreement On October 15, 2021, the Company entered into an agreement with the Bill and Melinda Gates Foundation (“Gates Foundation” or “BMGF”) by executing a Grant Agreement identified as Investment ID INV-033376 (“Grant”). The goal of the Grant Agreement is to develop durable approaches to block the infection and transmission of pathogens. For providing research and development services under the Grant Agreement, the Gates Foundation has agreed to compensate the Company $<span id="xdx_902_eus-gaap--ResearchAndDevelopmentArrangementContractToPerformForOthersCompensationEarned_pn4n6_c20211015__20211015__srt--CounterpartyNameAxis__custom--BillAndMelindaGatesFoundationMember__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zOLKU28zegW3" title="Amount of compensation">1.93 million due upon execution of the Grant Agreement. In return, we agreed to conduct a proof-of-concept study seeking to demonstrate that inhaled neutralizing antibodies are effective for preventing viral infection and transmission. We are required to ensure global access which means that the knowledge and information gained from the project will be promptly and broadly disseminated, and that the products, technologies, materials, processes and other intellectual property resulting from the proof-of-concept study (collectively referred to as the Funded Developments) will be made available and accessible at an affordable price (i) to people most in need within developing countries or (ii) in support of the U.S. educational system and public libraries. Under the Grant Agreement, the Gates Foundation made an upfront payment of $<span id="xdx_90C_eus-gaap--ProceedsFromLicenseFeesReceived_pn4n6_c20211015__20211015__srt--CounterpartyNameAxis__custom--BillAndMelindaGatesFoundationMember__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zfy7cciMyWka" title="Proceeds from license fees received">1.93 million. The Agreement specifies that we may not use funds provided under the Grant Agreement for any purpose other than the project. The Company is required to repay any portion of the funds used or committed in material breach of the Grant Agreement. Any grant funds, plus any income, that have not been used for, or committed to, the Project upon expiration or termination of the Agreement, must be returned promptly to the Gates Foundation. The Company will conduct research and development services up until the proof-of-concept study is completed, at which point the Gates Foundation will determine whether to approve further grant funding for transmission studies or end the study in which case the Company will no longer provide any significant goods or services. The Company will partner with three main subcontractors to deliver the scope of work described in the investment document. The Grant Agreement is considered within the scope of ASC 606 as the parties have a customer/vendor relationship and are not exposed equally to the risks and rewards of the research and development services contemplated in the Grant Agreement. The Company identified the following promises under the Agreement: 1) research and development services, 2) global access commitment, 3) humanitarian license, 4) publication if requested by the Gates Foundation, and 5) intellectual property reporting upon request. The Company determined that these promises are not distinct from each other, and therefore represent one performance obligation. Since the Company is required to update the Gates Foundation on technical progress during each stage of the Funded Development, the ability to access research and development results represents the Gates Foundation’s consumption of the benefits from the Company’s research and development activities. As such, research and development services revenue are recognized over time. At each reporting period, the amount of revenue to recognize is calculated using the input method (cost-to-cost), by comparing cumulative costs incurred to the total estimated costs to perform the research and development services and applying that percentage of completion to the transaction price. The Company believes this method best depicts the transfer of control to the customer, which occurs as the costs related to the research and development services are incurred. The Company recognized approximately $<span id="xdx_901_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_c20230701__20230930__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zkuYmKNs6ZSd" title="Liability revenue">0 and $<span id="xdx_90E_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_pn5n6_c20230101__20230930__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zHeB74qI3Zxf" title="Liability revenue">0.2 million in grant revenue related to the Grant Agreement for the three and nine month periods ended September 30, 2023 and approximately $<span id="xdx_90F_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_pn5n6_c20220701__20220930__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zjfdHlrXj658" title="Liability revenue">0.4 million and $<span id="xdx_905_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_pn5n6_c20220101__20220930__us-gaap--TypeOfArrangementAxis__custom--GrantsFoundationGrantAgreementMember_zohC0GajsH88" title="Liability revenue">0.6 million in grant revenue for the three and nine month periods ended September 30, 2022, respectively. The Company eliminated the contract liability in deferred revenue, current, on its condensed consolidated balance sheet as of September 30, 2023, as all the grant funding had been consumed. Serum License Agreement In July 2019, the Company and Serum International B.V. (“SIBV”), an affiliate of Serum Institute of India Private Limited, entered into an option agreement which granted SIBV the option to license multiple programs from the Company and access the Company’s MabIgX® platform technology for asset identification and selection. The Company received an upfront cash payment of $5 million upon execution of this option agreement. In connection with the option agreement, SIBV made an equity investment whereby the Company issued <span id="xdx_90C_eus-gaap--StockIssuedDuringPeriodSharesNewIssues_pid_c20190701__20190731__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockMember_zbyexs2NcxUk" title="Restricted common stock issuance">801,820 shares of its restricted common stock in a private placement to SIBV for total gross proceeds of $<span id="xdx_908_eus-gaap--ProceedsFromIssuanceOfPrivatePlacement_pn6n6_c20190701__20190731__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockMember_z1yImWaPaEL3" title="Private placement, value">10 million. As a result of this transaction, SIBV and its affiliates, are considered related parties to the Company. In September 2019, the Company and Serum AMR Products (“SAMR”), a party under common ownership of SIBV, entered into a License, Development and Commercialization Agreement (the “License Agreement”). Pursuant to the License Agreement, the Company granted to SAMR exclusive licenses, and rights to sublicense, certain patent rights and technology related know-how to the Company’s products AR-301, AR-105, AR-101 (i.e. exclusive rights to, among other things, develop, distribute, market, promote, sell, import and otherwise commercialize) in (a) the country of India, and (b) all other countries of the world except the USA, Canada, EU Territory, UK, China, Australia, South Korea, Brazil, New Zealand, and Japan (products AR-105 and AR-101 countries do not exclude South Korea and Brazil) (the “Limited Territory”); and AR-201 (i.e. exclusive rights to, among other things, develop, manufacture, make, distribute, market, promote, sell, import and otherwise commercialize) in all countries of the world except China, Hong Kong, Macau and Taiwan (the “Worldwide Territory”) (the “licenses and know-how”). Further, the License Agreement grants SAMR an option for the Company to provide research services using its MabIgX® platform technology for the identification of up to five (5) candidates including product development of these identified candidates and an exclusive license to develop, manufacture, make, distribute, market, promote, sell, import and otherwise commercialize these development products in the Worldwide Territory (the “research and development option”). Pursuant to the License Agreement, the Company will provide development support related to the licensed products above in order to assist SAMR in its efforts to develop, receive regulatory approval, and manufacture and sell the licensed products in SAMR’s authorized territories which will be performed under the direction of a Joint Steering Committee (“JSC”) which the Company will participate in (collectively “development support services”). In addition, under the License Agreement, SAMR was granted an exclusive manufacturing license option as the initial license granted above for AR-301, AR-105 and AR-101 does not allow for manufacturing. This manufacturing option provides incremental rights related to these products beyond what is granted as part of the licensing discussed above (the “manufacturing rights option”). If this option is exercised, after SAMR has met certain requirements to exercise the option as defined in the License Agreement, it would provide for an exclusive license for use by SAMR to manufacture and supply the products for SAMR’s own use in the Limited Territory and to manufacture and supply these products to the Company, or their affiliates, for the Company’s use outside the Limited Territory. Should SAMR exercise the development and research option or the manufacturing rights option discussed above, SAMR and the Company shall negotiate in good faith the economic terms around these arrangements. If a third-party sublicensee of AR-301, AR-105 and AR-101 wishes to manufacture these products by itself for the territory for which it has a license from the Company, then the Company shall have the right to buy back the manufacturing rights for all territories outside of the Limited Territory by paying to SAMR $5 million. Under the License Agreement, the Company received upfront payments totaling $15 million, of which $5 million was received in July 2019 through the option agreement referred to above. Given the equity investment by SIBV was negotiated in conjunction with the option agreement, which resulted in the execution of the License Agreement, all arrangements were evaluated as a single agreement and amounts were allocated to the elements of the arrangement based on their fair value. The Company recorded approximately $<span id="xdx_907_ecustom--NetProceedsOfRestrictedCommonStockFairValue_pn5n6_c20190101__20191231__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember_zcmf64zYeIWf" title="Fair value of net proceeds">5.0 million, which represented the fair value of the restricted common stock issued of $<span id="xdx_905_ecustom--GrossProceedsOfRestrictedCommonStockFairValue_pn5n6_c20190101__20191231__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember_zhDbJ6l3YX7g" title="Fair value of gross proceeds">5.4 million, net of $441,000 of issuance costs, to stockholders’ equity within the Company’s consolidated balance sheet as of December 31, 2019.

The License Agreement is determined to be within the scope of ASC 606, as the transaction represents a contract with a customer where the participants function in a customer/vendor relationship and are not exposed equally to the risks and rewards of the activities contemplated under the License Agreement. Using the concepts of ASC 606, the Company identified the following performance obligations under the License Agreement: 1) the transfer of licenses of the intellectual property for AR-301, AR-101, AR-105 and AR-201, inclusive of the related technology know-how conveyance (referred to as the license and know-how above); and 2) the Company to deliver ongoing development support services related to the licensed products and the Company’s participation in the JSC (referred to as the development support services above); and identified the following material promises under the License Agreement: 3) SAMR was granted a research and development option of up to five identified product candidates for the Company to perform including specific development services (the research and development option referred to above); and 4) SAMR was granted an exclusive manufacturing license option which would provide for incremental manufacturing rights related to AR-301, AR-105 and AR-101 beyond what is granted in the License Agreement (the manufacturing rights option referred to above). The Company concluded that the performance obligations and material promises identified are separate and distinct from each other. The Company determined that the transaction price under the License Agreement was $19.6 million, consisting of the $<span id="xdx_90E_ecustom--DeferredRevenueLicenseAgreement_iI_pn5n6_c20230930__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember_zdAx5RIzY7Bj" title="Deferred revenue based on upfront payments">15.0 million from upfront payments under the License Agreement and approximately $<span id="xdx_90D_ecustom--DeferredRevenueEquityAllocation_iI_pn5n6_c20230930__us-gaap--TypeOfArrangementAxis__custom--SerumLicenseAgreementMember_z6xbPU7w3Psf" title="Deferred revenue from equity allocation">4.6 million from the equity allocation as noted above, which was allocated among the performance obligations and material promises based on their respective related standalone selling prices.

The Kermode Agreement defines four phases of research and development activities. The Company is also entitled to royalty payments based on future net sales if Kermode is ultimately successful in commercializing product candidates. The Kermode Agreement is within the scope of ASC 606 as the parties have a customer/vendor relationship and are not exposed equally to the risks and rewards of the activities contemplated in the Kermode Agreement. The Company identified the following promises under the Kermode Agreement: 1) research and development services, and 2) license rights of the ʎPEX Platform and mAbs and vaccines (“Program IP”). The Company determined that these promises are not distinct from each other, and therefore represent one performance obligation. As of March 31, 2022, the transaction price of the Kermode Agreement was $1,000,000, consisting of the nonrefundable upfront payment of $<span id="xdx_905_ecustom--NonrefundableUpfrontPayment_c20220331__20220331__us-gaap--TypeOfArrangementAxis__custom--KermodeLicensingAndProductDiscoveryAgreementMember__srt--ProductOrServiceAxis__custom--ResearchAndDevelopmentOptionMember_zIqTrckscVEg" title="Nonrefundable upfront payment">500,000 and the two milestone payments, totaling $<span id="xdx_90A_ecustom--NonrefundableTwoMilestone_c20220331__20220331__us-gaap--TypeOfArrangementAxis__custom--KermodeLicensingAndProductDiscoveryAgreementMember__srt--ProductOrServiceAxis__custom--ResearchAndDevelopmentOptionMember_zQo4OPZWiI08" title="Nonrefundable milestone payments">500,000. Potential royalty payments were not included in the transaction price, as it was not probable that a significant reversal of cumulative revenue recognized would not occur if these amounts were included. At the end of each reporting period, the Company will update its assessment of whether the milestone payments and royalties are constrained by considering both the likelihood and magnitude of the potential revenue reversal. The Company determined that the one performance obligation under the Kermode Agreement should be recognized over time. At each reporting period, the amount of revenue to recognize will be calculated using the input method (cost-to-cost), by comparing cumulative costs incurred to the total estimated costs to perform all four phases of the research and development activities and applying that percentage of completion to the transaction price. The Company believes this method best depicts the transfer of control to the customer, which occurs as the costs related to the research and development activities are incurred. The Company recognized approximately $<span id="xdx_906_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_c20230701__20230930__us-gaap--TypeOfArrangementAxis__custom--KermodeLicensingAndProductDiscoveryAgreementMember_zfaMmmDh9QJ" title="Revenue recognized">0 and $<span id="xdx_900_eus-gaap--ContractWithCustomerLiabilityRevenueRecognized_pn5n6_c20230101__20230930__us-gaap--TypeOfArrangementAxis__custom--KermodeLicensingAndProductDiscoveryAgreementMember_zkAkdJaorqOc" title="Revenue recognized">0.1 million in grant revenue related to the Kermode Agreement for the three and nine month periods ended September 30, 2023 and approximately $0.1 million and $0.5 million in grant revenue for the three and nine month periods ended September 30, 2022, respectively. The Company has no remaining portion of the nonrefundable upfront payment as a contract liability on its condensed consolidated balance sheet as of September 30, 2023 as the statement of work was considered completed. National Institutes of Health / National Institute of Allergy and Infectious Diseases Grants In June 2023, the Company received a grant award from the National Institute of Allergy and Infectious Diseases division of the National Institutes of Health, in collaboration with researchers at Eitr Biosciences in San Diego, California, to develop pan-coronavirus human monoclonal antibody. The Company expects to commence work and receive funding under the collaboration in the fourth quarter of 2023. In August 2023, the Company received a grant award from the National Institute of Allergy and Infectious Diseases division of the National Institutes of Health, in collaboration with researchers at Emory University in Atlanta, Georgia, to apply the company’s APEXTM human monoclonal antibody (“mAb’) discovery and production platform technology to discover and develop antibacterial mAbs from patients. The Company expects to commence work and receive funding under the collaboration in the fourth quarter of 2023. The academic COMBACTE-NET consortium partners initially pay for all costs incurred at EU clinical sites and subsequently bills the Company for 25% of such costs. Specifically, we are billed for 25% of eligible costs during the entire fiscal year six to seven months following the fiscal year. The work at these sites is performed entirely by third-party subcontractors. As such, we reimburse the 25% at the passed-through invoice amounts. There is no reimbursement for costs incurred at non-EU sites.

On September 30, 2022, the Company signed an amendment to promissory note #2. Subject to certain provisions and so long as no Event of Default has occurred, then in addition to the three (3) deferral rights previously available, the Company shall have the right to exercise additional monthly deferrals until March 31, 2023 (each, an “Additional Deferral”). Each time Borrower exercises an Additional Deferral the Outstanding Balance will automatically be increased by 1.5%. As of March 31, 2023, the Company has not made any payments on Note #2. In April 2023, the Company entered into a Note Purchase and Loan Restructuring Agreement with Streeterville Capital, LLC modifying the principal amount of Note #2 from approximately $5,250,000 to approximately $9,287,000 in exchange for an additional investment amount of up to $2,500,000. Pursuant to the Note Purchase Agreement, we are subject to certain covenants, including the obligations to: (i) timely file all reports required to be filed under Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and not terminate its status as an issuer required to file reports under the Exchange Act; (ii) maintain listing of our common stock on a securities exchange; and (iii) avoid trading in our common stock from being suspended, halted, chilled, frozen or otherwise ceased. The Company was in compliance with all covenants as of March 31, 2023. On April 17, 2023, the Company was no longer in compliance as it didn’t meet the timely filing of the annual report on 10-K. The Company has received a waiver from the lender for this covenant which also included waiving compliance for timely filing of the May 15, 2023 10Q filing for the period ended March 31, 2023. The Note is secured by the Company’s MabIgX assets and Note #2 is secured by all of the Company’s assets. On July 20, 2023, Streeterville provided a waiver with respect to the breach of Section 4(ii) of that certain Note Purchase Agreement dated November 23, 2021, in connection with the recent delisting of the Company’s common stock from Nasdaq to OTC Markets Pink Sheets. This in turn means that no such Event of Default has occurred pursuant to Section 4.1(l) of Secured Promissory Note #1 dated November 23, 2021, with respect to the recent delisting. Additionally, Streeterville provided a waiver with respect to the breach of Section 4(ii) and 4(iii) of that certain Note Purchase and Loan Restructuring Agreement dated April 26, 2023, in connection with the recent delisting of the Company’s common stock from Nasdaq to OTC Markets Pink Sheets. This in turn means that no such Triggering Event has occurred pursuant to Section 4.1(h) of Secured Promissory Note dated April 26, 2023, with respect to the recent delisting. On August 31, 2023, Streeterville provided a waiver with respect to the breach of Section 4(i) of that certain Note Purchase and Loan Restructuring Agreement dated April 26, 2023, in connection with the delinquent filing of the Company’s Quarterly Report for the period ended June 30, 2023 on Form 10-Q with the SEC. This in turn means that no such Triggering Event has occurred pursuant to Section 4.1(h) of Secured Promissory Note dated April 26, 2023, with respect to the delinquent filing. On September 22, 2023, the Company entered into an Exchange Agreement (the “September 2023 Exchange Agreement”) with Streeterville, pursuant to which we agreed to (i) partition from the Note a new Promissory Note (the “September 2023 Partitioned Note”) in the original principal amount of $50,000 (the “September 2023 Exchange Amount”), (ii) cause the outstanding balance of the Note to be reduced by an amount equal to the September 2023 Exchange Amount, and (iii) exchange (the “September 2023 Exchange”) the September 2023 Partitioned Note for 898,069 shares of the Company’s common stock. On September 22, 2023 the fair value of the shares issued was approximately $<span id="xdx_901_eus-gaap--StockIssuedDuringPeriodValueNewIssues_pn3n3_c20230922__20230922__us-gaap--TypeOfArrangementAxis__custom--ExchangeAgreementMember_zCXYagTtZyHd" title="Stock issued during period, new issues">99 thousand and we immediately recorded $49 thousand as stock issuance costs through a reduction to additional paid-in-capital. The September 2023 Exchange was effected pursuant to one or more exemptions from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). There are no gross proceeds to the Company in respect of the September 2023 Exchange, provided that all of the September 2023 Exchange Amount will be applied to settle the September 2023 Partitioned Note. The fair value measurement includes interest, at the stated rate, and this separate amount is not reflected in the consolidated statement of operations. The Company has recorded a liability of approximately $3.4 million in Notes Payable (current) for both Notes, as of September 30, 2023. Insurance Financing The Company obtained financing for certain Director & Officer liability insurance policy premiums. The agreement assigns First Insurance Funding (Lender) a first priority lien on and security interest in the financed policies and any additional premium required in the financed policies including (a) all returned or unearned premiums, (b) all additional cash contributions or collateral amounts assessed by the insurance companies in relation to the financed policies and financed by Lender, (c) any credits generated by the financed policies, (d) dividend payments, and (e) loss payments which reduce unearned premiums. If any circumstances exist in which premiums related to any Financed Policy could become fully earned in the event of loss, Lender shall be named a loss-payee with respect to such policy. The total premiums, taxes and fees financed was approximately $<span id="xdx_90A_eus-gaap--FinancialGuaranteeInsuranceContractsPremiumReceivable_iI_pn5n6_c20230930__us-gaap--ShortTermDebtTypeAxis__custom--InsuranceFinancingNotePayableMember_zP4V1hefVwB3" title="Total premiums, taxes and fees financed">0.9 million with an annual interest rate of <span id="xdx_90C_eus-gaap--FinancialGuaranteeInsuranceContractsPremiumReceivedOverContractPeriodPremiumReceivableWeightedAverageRiskFreeDiscountRate_pid_dp_uPure_c20230101__20230930__us-gaap--ShortTermDebtTypeAxis__custom--InsuranceFinancingNotePayableMember_zQVkJSrgWyTe" title="Annual interest rate">5.129%. In consideration of the premium payment by Lender to the insurance companies or the Agent or Broker, the Company unconditionally promised to pay Lender the amount Financed plus interest and other charges permitted under the Agreement. The Company paid the insurance financing through installment payments and paid the remaining balance in May 2023. Accordingly, the Company had no liability recorded as of September 30, 2023 and a liability of approximately $0.5 million recorded in Note Payable as of December 31, 2022.

Commitments and Contingencies Facility Lease The Company determines if an arrangement is a finance lease, operating lease or short-term lease at inception, or as applicable, and accounts for the arrangement under the relevant accounting literature. Currently, the Company is only party to a non-cancelable office space operating lease. Under the relevant guidance, the Company recognizes operating lease ROU assets and liabilities based on the present value of the future minimum lease payments over the lease term at the commencement date, using the Company’s assumed incremental borrowing rate of 6%, and amortizes the ROU assets and liabilities over the lease term. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may incur charges in the future as a result of these indemnification obligations. License Agreements The Company has entered into various collaboration and licensing agreements that provide it with access to certain technology and patent rights. Under the terms of the agreements, the Company may be required to make milestone payments upon achievement of certain development and regulatory activities. None of these events occurred as of September 30, 2023. See “Development and License Agreements” in Note 6 of our Notes to the Condensed Consolidated Financial Statements. Contingencies From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a liability for such matters when it is probable that a potential loss will be incurred and such amount can be reasonably estimated. As of September 30, 2023, and December 31, 2022, no accruals have been made related to commitments and contingencies. From time to time, the Company may be involved in various legal proceedings, claims and litigation arising in the ordinary course of business. See below Legal Proceedings ongoing at September 30, 2023. Legal Proceedings A complaint was filed in February 2020 in the New York State Supreme Court against the Company by an investor who invested in the Company’s preferred stock in July 2017 prior to the Company’s IPO in August 2018. The complaint alleges, among other things, that the Company breached its contract and fiduciary duty, by not issuing additional securities to the investor as a result of the Company’s IPO. The plaintiff is asking for approximately $277,000 in compensatory damages, although in a recent motion practice the plaintiff indicated that it wants the stock purchase agreement between the parties, entered into prior to the IPO, to be rescinded and a return of the original purchase price of $531,687. Discovery has been completed and the parties filed competing motions for summary judgment on all claims. The Court heard oral argument on those motions on January 12, 2023. The parties now await the Court’s decision. We believe that the claims in this complaint are without merit and intend to continue to defend vigorously against them. The Company submitted a complaint in Superior Court of the State of California, County of Santa Clara, against our former landlord on October 22, 2021, asserting claims for breach of contract, breach of the covenant of good faith and fair dealing, wrongful eviction/constructive eviction and unjust enrichment and violation of the unfair competition law. The claims arise from rent increases and the termination of the tenancy that we allege were not permitted by the agreement with the landlord. We seek to recover rent paid under protest, our deposit, moving and relocation expenses and consequential damages arising from disruption to our operations. The Company filed a first amended complaint on July 18, 2022 asserting the same claims. The landlord has filed a cross-complaint for damage to property and attorneys’ fees. The court has set a trial setting conference for February 20, 2024. The parties have agreed to mediate the dispute and mediation is on-going. The Company accrues a liability for such matters when it is probable that potential loss will be incurred and such amount can be reasonably estimated. As of September 30, 2023, and December 31, 2022, no liability has been recognized in relation to these matters. Grant Income The Company receives various grants that are subject to audit by the grantors or their representatives. Such audits could result in requests for reimbursement for expenditures disallowed under the terms of the grant. As of September 30, 2023, management has complied with all of the required grant terms. There are no grant audits currently in process.

Under the award agreement, the CFF will make payments to the Company as certain milestones are met. See Note 6 for details of the grant agreement.

The Company is also entitled to additional payments from Kermode for royalty payments on future net sales (see Note 6). In the event that the research and development efforts under the agreement are successful and if the Company elects to develop and commercialize products under certain provisions contained in the agreement, the Company shall pay to Kermode a 5% royalty of net sales from those products. None of these events occurred as of September 30, 2023.
