Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis together with our financial statements and related notes included in “Item 8. Financial Statements and Supplementary Data” in this Annual Report. The following discussion contains forward-looking statements that involve risks and uncertainties. For a complete discussion of forward-looking statements, see the section above entitled “Forward Looking Statements.” Our actual results could differ materially from those expressed or implied in any forward-looking statements as a result of various factors, including those set forth under the caption “Item 1A. Risk Factors.”

Overview

We are a biopharmaceutical company focused on the development of our novel, potentially first-in-class product candidate, neffy (previously referred to as ARS-1) for the emergency treatment of Type I allergic reactions, including anaphylaxis. neffy is a proprietary composition of epinephrine with an innovative absorption enhancer called Intravail®, which allows neffy to provide intranasal delivery of epinephrine.

We believe neffy’s “no needle, no injection” approach will address a significant unmet need in the use of epinephrine, which is currently approved only in injectable formulations for the emergency treatment of Type I allergic reactions. There are approximately 25 to 40 million people in the United States who experience Type I allergic reactions. Of this group, approximately 16 million people have been diagnosed and experienced severe Type I allergic reactions that may lead to anaphylaxis, but only 3.3 million currently have an active epinephrine autoinjector prescription, and of those, only half consistently carry their prescribed autoinjector with them due to the many drawbacks of these devices. In aggregate, we estimate that 90% of patients prescribed an epinephrine device are not achieving an optimal treatment outcome today. These drawbacks include the use of needles in the devices, which can result in patient and caregiver injury as well as hesitation and delays in administration due principally to apprehension and pain of needles, allowing the allergic reaction to progress in severity leading to symptoms that seriously impact patient quality of life, to potential need for emergency services and/or hospitalizations, and to life-threatening symptoms or events. Intra-muscular injections also are subject to dosing errors and risk of accidental blood vessel injections, which can cause a significant spike in the intravascular delivery of epinephrine potentially leading to serious cardiovascular complications or events. We believe neffy’s “no needle, no injection” delivery that eliminates apprehension, pain and safety concerns, small size allowing for ease of portability, ease of use, and high reliability provide it with a user-friendly profile that will increase prescriptions for epinephrine and make it more likely for patients and caregivers to administer epinephrine sooner, achieve more rapid symptom relief and prevent the allergic reaction from progressing to a level of severity that could lead to hospitalization or even death.

Data from our studies of neffy demonstrated nasally delivered epinephrine reached blood levels comparable to those of already approved epinephrine injectable products. Our NDA was accepted for review by FDA in the fourth quarter of 2022 with an anticipated mid-2023 PDUFA target action date and if our NDA is approved, we believe neffy will be the first “no needle, no injection” marketed epinephrine product for the emergency treatment of Type I allergic reactions. However, the timing for regulatory approvals is outside our control, may be delayed and is uncertain.

Since our inception in 2015 as ARS Pharmaceuticals, Inc., we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, performing research and development activities, and providing general and administrative support for these operations. We do not have any products approved for sale and have not generated any product sales. We have funded our operations primarily with proceeds from the Merger, private placement of convertible preferred stock, licensing, supply and distribution arrangements with our commercialization partners, and bank debt. From inception to December 31, 2022, we have raised $262.3 million in cash, cash equivalents and short-term investments, net of transaction costs, from the Merger, net proceeds of $76.3 million from the issuance of convertible preferred and common stock, $27.8 million from our collaboration, licensing, supply and distribution arrangements, and $10.0 million from bank debt. As of December 31, 2022, we had cash, cash equivalents, and short-term investments of $274.4 million.

96

We have incurred net losses from operations since our inception. Our net loss was $34.7 million for the year ended December 31, 2022 and as of December 31, 2022 we had an accumulated deficit of $76.9 million. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials, our expenditures on other development activities, the cost for regulatory filings, expenses for pre-commercial activities to establish sales, marketing and distribution capabilities for our product candidates, and our ability to earn potential regulatory and commercial milestones under our collaboration arrangements. We expect our expenses and operating losses will increase substantially as our product candidate, neffy potentially is approved by the FDA and we commence commercialization efforts, any future product candidates advance through clinical trials, we expand our clinical, regulatory, quality, manufacturing and pre-commercial sales and marketing capabilities, and incur additional costs to operate as a public company following the completion of the Merger. If we obtain marketing approval for any of our product candidates, we will incur significant commercialization expenses for marketing, sales, manufacturing and distribution activities, and added expenditures to expand our operational, financial and management systems and increase personnel to support these operations.

We do not expect to generate any revenues from product sales unless and until we successfully obtain regulatory approval for one or more product candidates, if ever. Until such time, if ever, as we can generate substantial product revenue, we may finance our operations through our existing cash, cash equivalents, short-term investments, equity offerings, debt financings and other capital sources which may include collaborations, strategic alliances, marketing, distribution or licensing arrangements or other arrangements with third parties. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. In addition, any future debt agreements may limit our ability to enter into certain debt financings without the consent of the lenders thereunder. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and may require us to delay, reduce or terminate our research and development programs or other operations, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We do not own or operate manufacturing facilities. We currently rely on third-party manufacturers and suppliers for neffy, and we expect to continue to do so to meet our nonclinical, clinical and any commercial activities. Our third-party manufacturers are required to manufacture our product candidates under cGMP requirements and other applicable laws and regulations.

Merger

On November 8, 2022 (the “Closing Date”), privately-held ARS Pharmaceuticals, Inc. (“ARS Pharma ) merged with Silverback Therapeutics, Inc., a Delaware corporation (“Silverback”), a publicly traded company. In accordance with the terms of the agreement and plan of merger and reorganization, dated July 21, 2022, as amended on August 11, 2022 and October 25, 2022 (the “Merger Agreement”), Sabre Merger Sub, Inc. (“Merger Sub”), a wholly-owned subsidiary of Silverback, merged into ARS Pharma, with ARS Pharma surviving as Silverback’s wholly-owned subsidiary. At the completion of the Merger, the prior ARS Pharma equityholders owned 62% and the prior Silverback equityholders owned 38% of the combined company, in each case on a fully diluted basis using the treasury stock method and excluding out-of-money options of Silverback. Upon completion of the Merger, Silverback changed its name to ARS Pharmaceuticals, Inc. As, among other facts, the stockholders of ARS Pharma owned a majority of the combined company, the Merger was treated for accounting purposes as if ARS Pharma had acquired Silverback. As a result of the Merger being accounted for as if ARS Pharma had acquired Silverback, the financial statements of ARS Pharma are presented as the historical financial statements of the combined company for all periods presented.

At the effective time of the Merger (the “Effective Time”), each share of ARS Pharma common stock outstanding immediately prior to the Effective Time, after giving effect to the automatic conversion of all shares of preferred stock of ARS Pharma into shares of ARS Pharma common stock immediately prior to the Effective Time (the “Preferred Stock Conversion”), (excluding shares held as treasury stock by ARS Pharma or held or owned by Silverback, Merger Sub or any subsidiary of Silverback or ARS Pharma and dissenting shares) were automatically converted into the right to receive shares of Silverback common stock equal to the exchange ratio of 1.1819. Outstanding and unexercised options and warrants to purchase shares of ARS Pharma common stock were converted into options and warrants to purchase shares of Silverback common stock.

Recent Events

In September 2020, we entered into a license and supply agreement (the “Recordati License and Supply Agreement”) with Recordati Ireland, Ltd (“Recordati”). Pursuant to the Recordati License and Supply Agreement, we granted Recordati an exclusive, royalty-bearing, sublicensable license under our patents relating to neffy to (i) perform Recordati’s development activities on the epinephrine compositions (“Recordati Licensed Compositions”) and related products (“Recordati Licensed Products”) for commercialization in the EU, United Kingdom, and certain countries in the Middle East, Africa and Eurasia (the “Recordati Territory”), (ii) manufacture (or have manufactured) the Recordati Licensed Products for commercialization in the Recordati Territory, (iii) file and hold regulatory approvals for the Licensed Products in the Recordati Territory, and (iv) commercialize the Recordati Licensed Products in the Recordati Territory (collectively, the “Recordati Rights”).

97

On February 22, 2023, we entered into the Termination Agreement with Recordati, pursuant to which, among other things, we and Recordati agreed to terminate the Recordati License and Supply Agreement. Pursuant to the Termination Agreement, we will reacquire all of the Recordati Rights and have agreed to pay Recordati a one-time upfront payment of €3.0 million and additional payments upon achievement of certain milestones including: (i) an EMA regulatory milestone payment of €2.0 million, (ii) a milestone payment of €5.0 million upon first commercial sale of a Recordati Licensed Product in the Recordati Territory, and (iii) milestone payments of up to €5.0 million in the aggregate from sales of Recordati Licensed Product(s) in the Recordati Territory.

Financial Overview

Revenues

To date, we have not generated any revenues from the commercial sale of any products, and we may not generate revenues from the commercial sale of any products. We have signed collaboration and license agreements including supply and distribution for neffy with Alfresa Pharma in Japan and Pediatrix in China. The terms of these agreements may include payment to us of one or more of the following: non-refundable, up-front license fees; clinical, regulatory, and/or commercial milestone payments; clinical development fees; and royalties or a transfer price on net sales of licensed products if neffy receives marketing approval in these regions. In addition, we previously entered into the Recordati License and Supply Agreement, which was terminated in February 2023. We expect revenues to fluctuate in future periods based on our ability to meet various regulatory milestones, and contingent on successfully obtaining regulatory approval for neffy in the US and the licensed regions, US product sales, commercial milestones, royalties or transfer price earned from our partner’s net sales and the supply of commercial product as set forth in the agreements described earlier.

Research and Development Expenses

To date, our research and development expenses have related primarily to clinical development, process development and manufacturing costs of our product candidate. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.

Research and development expenses include:

• indirect expenses including insurance and facility-related expenses.

Our external research and development expenses for our clinical stage product candidate consists primarily of fees, materials and other costs paid to CROs, CMOs, consultant and contractors. Our clinical trials and manufacturing costs for the periods presented below reflect an allocation of expenses associated with personnel costs, equity-based compensation expense, and indirect costs incurred in support of overall research and development, such as facilities-related costs.

We expect that our research and development expenses will likely decrease in 2023 based on our planned clinical development and manufacturing activities, as we plan to transition to commercialization efforts for the potential launch of our first product that year. However, the timing for regulatory approvals is outside our control, may be delayed and is uncertain. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future clinical trials and the manufacturing costs of our product candidates due to the inherently unpredictable nature of clinical development and manufacturing activities. Clinical development and manufacturing timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future clinical trials, regulatory developments and our ongoing assessments as to each product candidate’s commercial potential. In addition, we cannot forecast to what degree our licensing, supply and distribution arrangements would affect our development plans and capital requirements.

98

The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors that include:

• per patient trial costs;

• the number of patients that participate in the trials;

• the number of sites included in the trials;

• the countries in which the trials are conducted;

• the length of time required to enroll eligible patients;

• the number of doses that patients receive;

• the drop-out or discontinuation rates of patients;

• the efficacy and safety profile of our product candidates, and

• significant and changing government regulation and regulatory guidance;

A change in the outcome of any of these variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. The process of conducting the necessary clinical research and manufacturing to obtain regulatory approval is costly and time-consuming. The actual probability of success for our product candidates or any future candidates may be affected by a variety of factors. We may never succeed in achieving regulatory approval for our product candidates or any future candidates. Further, a number of factors, including those outside of our control, could adversely impact the timing and duration of our product candidates’ or any future candidates’ development, which could increase our research and development expenses.

General and Administrative

General and administrative expenses consist primarily of salaries, benefits, equity-based compensation for personnel in executive, finance, business development, sales and marketing and other corporate administrative functions. General and administrative expenses also include legal fees incurred relating to corporate and patent matters, professional fees incurred for accounting, auditing, tax and administrative consulting services, facility costs, market research costs, and insurance costs.

We anticipate our general and administrative expenses will increase substantially in 2023 as we add sales and marketing personnel, infrastructure and programs to support pre-commercial activities, and if our product candidates receive marketing approval, commercialization activities. We also anticipate increased general and administrative personnel to support our operations, and higher patent and facility related costs. We also expect to incur added audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums, board of director fees, and investor relations costs associated with operating as a public company following the Merger.

99

Total Other Income (Expense)

Total other income (expense) consists primarily of interest expense from bank debt, interest income from our cash, cash equivalents, and investments, and changes in the fair value of our warrant liability prior to the Merger. As a result of the Merger, the warrant liability was reclassified to equity and fair value adjustments are no longer required.

Results of Operations

Comparison of the Years Ended December 31, 2022 and 2021:

The following table summarizes our results of operations for the years ended December 31, 2022 and 2021 (in thousands, except percentages):

Years Ended December 31, Dollar %

Revenue under collaboration agreements $ 1,316 $ 5,506 $ (4,190 ) (76 %)

Operating expenses:

Unrealized gain on available-for-sale securities 407 — 407 100

______________

(1) Includes stock-based compensation expense as follows (in thousands):

Years Ended December 31,

Research and development $ 213 $ 2,114

General and administrative 5,630 715

Revenues. Revenue under collaboration agreements was $1.3 million and $5.5 million for the years ended December 31, 2022 and 2021, respectively. The revenues for the years ended December 31, 2022 and 2021 include the recognition of revenue for the portion of upfront and clinical and regulatory milestone payments under our collaborations with Alfresa and Recordati that have been allocated to research and development services provided for during the years. Revenue under these collaboration agreements decreased $1.2 million from 2021 to 2022. The remaining decrease from 2021 to 2022 is due to the recognition of an upfront payment of $3.0 million under our collaboration and distribution agreement with Pediatrix signed in March 2021 relating to the issuance and delivery of a technology license, with no comparable activity in 2022. We expect revenues to fluctuate in future periods based on our ability to meet various regulatory milestones, and contingent on successfully obtaining regulatory approval for neffy in the licensed regions, commercial milestones, royalties or transfer price earned from our partner’s net sales and the supply of commercial product as set forth in these agreements.

Research and Development Expenses. Research and development expenses were $18.4 million and $20.3 million for the years ended December 31, 2022 and 2021, respectively. The decrease of $1.9 million was primarily due to a $3.1 million decrease in clinical trial costs associated with neffy and a $1.9 million decrease in stock-based compensation. These aggregated decreases were partially offset by $1.1 million in in-process research and development acquired in the Merger, a $1.0 million increase in license fees for the milestone payment to Aegis upon the FDA’s acceptance of our US NDA filing, and a $0.9 million increase in regulatory consulting costs.

Years Ended December 31,

Manufacturing and non-clinical development 9,482 9,713

Total research and development expenses $ 18,376 $ 20,273

100

General and Administrative Expenses. General and administrative expenses were $18.5 million and $4.7 million for the years ended December 31, 2022 and 2021, respectively. The increase of $13.8 million was primarily due to a $4.9 million increase in stock-based compensation of which $3.0 million was for the replacement of stock awards held by Silverback employees and directors in connection with the Merger and $1.3 million for the vesting of previously issued performance-based options, a $3.6 million increase in outside services associated with marketing and consulting, a $2.3 million increase in legal fees, a $2.2 million increase in payroll and related expenses, and a $0.6 million increase in insurance costs.

Total Other Income (Expense). Total other income was $0.8 million for the year ended December 31, 2022 and total other expense was $0.8 million for the year ended December 31, 2021. The difference of $1.6 million was primarily due to a $1.8 million increase in interest income from our cash, cash equivalents, and investments partially offset by a $0.1 million loss due to the change in fair value of the preferred stock warrant liability.

Liquidity and Capital Resources

Sources of Liquidity and Capital

Since our inception, we have not generated any revenue from any product sale and have incurred significant operating losses and negative cash flows from our operations. We have not yet commercialized any of our product candidates and we do not expect to generate revenue from sales of any product candidates until the second half of 2023 or after, if at all. We have funded our operations to date primarily with proceeds from the Merger, the sale of preferred and common stock, revenue earned under collaboration, licensing, supply and distribution agreements and bank debt. From inception to December 31, 2022, we have raised $262.3 million in cash, cash equivalents and short-term investments, net of transaction costs, from the Merger, net proceeds of $76.3 million from the issuance of convertible preferred and common stock, $27.8 million from our collaboration, licensing, supply and distribution arrangements, and $10.0 million from bank debt. As of December 31, 2022, we had cash, cash equivalents, and short-term investments of $274.4 million.

Cash flows

The following table summarizes our cash flows for the years ended December 31, 2022 and 2021 (in thousands):

Years Ended December 31,

Net cash and cash equivalents used in investing activities (199 ) (55 )

Net cash and cash equivalents provided by financing activities 190,732 53,158

Net increase in cash and cash equivalents $ 150,455 $ 35,542

Operating Activities

During the year ended December 31, 2022, net cash used in operating activities was $40.1 million. This consisted primarily of a net loss of $34.7 million and an increase in our operating assets and liabilities of $12.8 million, partially offset by non-cash charges of $7.4 million. The increase in our operating assets and liabilities was primarily due to a decrease in accounts payable and accrued liabilities of $10.3 million, an increase in prepaid and other assets of $1.2 million, and a decrease in contract liability of $1.3 million. The non-cash charges primarily consisted of non-cash stock-based compensation of $5.8 million, acquired in-process research and development of $1.1 million, depreciation, amortization and accretion expense of $0.3 million, and change in fair value of warrant liability of $0.1 million.

During the year ended December 31, 2021, net cash used in operating activities was $17.6 million. This consisted primarily of a net loss of $20.2 million and an increase in our operating assets and liabilities of $0.4 million, partially offset by non-cash charges of $3.0 million. The increase in our operating assets and liabilities was primarily due to a decrease in contract liability of $2.5 million, partially offset by a decrease in prepaid and other assets of $1.2 million and an increase in accounts payable and accrued liabilities of $1.0 million. The non-cash charges primarily consisted of stock-based compensation of $2.8 million and depreciation, amortization and accretion expense of $0.2 million.

Investing Activities

During the year ended December 31, 2022, the cash and cash equivalents used in investing activities was primarily due to $0.2 million in purchases of property and equipment. During the year ended December 31, 2021, the cash and cash equivalents used in investing activities was primarily due to $0.1 million in purchases of property and equipment.

101

Financing Activities

During the year ended December 31, 2022, the cash and cash equivalents provided by financing activities was primarily due to $198.8 million in net proceeds from the Merger. In addition, we acquired $63.5 million in short-term investments through the Merger. Also, during the year ended December 31, 2022, we used cash of $8.7 million for repayment of the bank note. During the year ended December 31, 2021, the cash and cash equivalents provided by financing activities was primarily due to $54.8 million of proceeds from the issuance of Series D convertible preferred stock in August 2021 plus $0.2 million from common stock option exercises, partially offset by $1.8 million repayments on the bank note.

Future Funding Requirements

Based on our current operating plan, we believe that our existing cash and cash equivalents will be sufficient to meet our anticipated cash requirements through at least the next three years. In particular, we expect our cash, cash equivalents, and short-term investments will allow us to fund our expenses related to the FDA’s review of our NDA for neffy, fund proof of concept clinical trials of neffy for additional indications, fund pre-commercial manufacturing and sales and marketing activities, and if and when neffy is approved by the FDA, fund our commercial launch. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we expect. Additionally, the process of testing product candidates in clinical trials is costly, and the timing of progress and expenses in these trials is uncertain.

Our future funding requirements will depend on many factors, including:

• the costs of operating as a public company.

102

Until such time, if ever, as we can generate substantial product revenues to support our cost structure, we expect to finance our cash needs through a combination of our existing cash, cash equivalents, short-term investments, equity offerings, debt financings and other capital sources which may include collaborations, strategic alliances, marketing, distribution or licensing arrangements or other arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. In addition, our current or future debt agreements may limit our ability to incur additional debt. If we raise funds through additional collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, development programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock.

Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and disruptions to and volatility in the credit and financial markets in the US, including due to recent bank failures, and worldwide resulting from macroeconomic factors. Because of the numerous risks and uncertainties associated with product development, we cannot predict the timing or amount of increased expenses and cannot assure you that we will ever be profitable or generate positive cash flow from operating activities.

Material Cash Requirements

Under our license agreement with Aegis, we have payment obligations of up to $20.0 million contingent upon our achievement of certain regulatory and commercial milestones and are required to make royalty payments in connection with the sale of products developed under that agreement. We are unable to estimate the timing or likelihood of achieving additional milestones or royalty payments under this agreement. We are also responsible for reimbursing Aegis for patent costs incurred in connection with prosecuting and maintaining patent rights that are specific to epinephrine or epinephrine products.

Pursuant to the Termination Agreement with Recordati, we have payment obligations of up to €10.0 million contingent upon our achievement of certain regulatory and commercial milestones, and up to €5.0 million based on a low double-digit percentage of sales of sales of Recordati Licensed Product(s) in the Recordati Territory We are unable to estimate the timing or likelihood of achieving these milestones and sales-based payments under this agreement.

In October 2021, we entered into a lease agreement to rent office space with a lease commencement date of December 2021. The lease has a term of 38 months. Annual rent expense is $0.2 million and is subject to annual increases of 3%, plus our share of operating expenses and taxes.

We enter into contracts in the normal course of business with third-party contract organizations and vendors for clinical studies, manufacturing and other services and products. These contracts generally provide for termination after a notice period.

To date, we have not recognized any reserves related to uncertain tax positions. As of December 31, 2022, we had no accrued interest or penalties related to uncertain tax positions.

Critical Accounting Policies and Significant Judgements and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenues recognized under collaboration agreements, accruals for research and development expenses and valuation of equity awards. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies and estimates are described in more detail in Note 2- Summary of Significant Accounting Policies to our consolidated financial statements, we believe the following accounting policies and estimates to be most critical to the preparation of our consolidated financial statements.

103

Revenue

Our revenues generally consist of licenses and research services under license and collaboration agreements.

We recognize revenue when we transfer promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) we satisfy the performance obligation(s). At contract inception, we assess the goods or services promised within each contract, assess whether each promised good or service is distinct and identify those that are performance obligations. We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The upfront payments and fees received prior to satisfying the relevant revenue recognition criteria are recorded as contract liability in the balance sheet and recognized as revenue when the related revenue recognition criteria are met.

Collaboration agreements typically contain multiple elements, or performance obligations, including research and development services and technology licenses. Our assessment of what constitutes a separate performance obligation requires us to apply judgement. Specifically, we have to identify which goods and services we are required to provide under the contract are distinct. For our collaboration agreements, we have identified several performance obligations at the inception of the contract since the delivered elements are deemed capable of being distinct within the context of the contract. Accordingly, the initial transaction price is allocated to the various performance obligations where we recognized revenue related to the license, which was delivered upon contract inception, and the remaining performance obligation is recognized as the underlying services are provided under the cost-based input method over the research terms. Using the cost-based input method, we recognize revenue based on actual costs incurred as a percentage of total estimated costs as we complete our performance obligations. Any cumulative effect of revisions to estimated costs to complete our performance obligations is recorded in the period in which changes are identified and amounts can be reasonably estimated. This approach requires us to use significant judgement and make estimates of future expenditures. If our estimates or judgements change over the course of the collaboration, they may affect the timing and amount of revenue that it recognizes in the current and future periods.

The transaction price for a contract represents the amount to which we are entitled in exchange for providing goods and services to the customer. The transaction price does not include amounts subject to uncertainties unless it is probable that there will be no significant reversal of revenue when the uncertainty is resolved. Apart from the upfront license payment and certain milestones, all other fees we may earn under our collaborative agreements are subject to significant uncertainties of product development and commercial sales targets. The transaction price of an agreement is allocated to each performance obligation on a relative stand-alone selling price basis, for which we recognize revenue as or when the performance obligations under the contract are satisfied.

Accrued Research and Development

We have entered into various agreements with CROs, CMOs, and other service providers. Our research and development accruals are estimated based on the level of services performed, progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research and development provided, but not yet invoiced, are included in accrued liabilities on the balance sheet. If the actual timing of the performance of services or the level of effort varies from the original estimates, we will adjust the accrual accordingly. Payments made to third parties under these arrangements in advance of the performance of the related services are recorded as prepaid expenses and other current assets until the services are rendered. Although we do not expect our estimates to be materially different from amounts actually incurred, if our estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in us reporting amounts that are too high or too low in any particular period. To date, our estimated accruals have not differed materially from actual costs incurred.

Stock-Based Compensation

Stock-based compensation expense represents the grant date fair value of equity awards recognized in the period using the Black-Scholes option pricing model. We recognize the expense for equity awards on a straight-line basis over the requisite service periods of the awards, which is usually the vesting period. Forfeitures are recognized as they occur. Estimating the fair value of equity awards pursuant to the Black-Scholes option pricing model requires us to make assumptions regarding a number of variables, including the risk-free interest rate, the expected stock price volatility, the expected term of stock options, the expected dividend yield and the fair value of the underlying common stock on the date of grant. Changes in these assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized.

104

The Black-Scholes option pricing model utilizes inputs which are highly subjective assumptions and generally require significant judgment. We determine these assumptions in the following manner:

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of ARS Pharmaceuticals, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ARS Pharmaceuticals, Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity (deficit) and cash flows for each of the two years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Financial Statements

1. Nature of Business

Description of Business

ARS Pharmaceuticals, Inc. (“ARS” or the “Company”) is focused on the development of ARS-1 (brand name neffy®), a proprietary product candidate for the needle-free intranasal delivery of epinephrine for the emergency treatment of type 1 allergic reactions including anaphylaxis. The Company incorporated in Delaware in January 2016 and is located in San Diego, California. The Company has a wholly owned subsidiary, ARS Pharmaceuticals Operations, Inc., incorporated in Delaware in August 2015 through which it conducts substantially all its operations, which survived the Merger as more fully described below. ARS Pharmaceuticals Operations, Inc. has a wholly owned subsidiary in Ireland, ARS Pharmaceuticals IRL, Limited, to facilitate the filing of regulatory approval for neffy in European countries.

Merger Transaction

On November 8, 2022 (the “Closing Date”), Silverback Therapeutics, Inc., a Delaware corporation (“Silverback”), now known as ARS Pharmaceuticals, Inc., completed its reverse merger (the “Merger”) with privately-held ARS Pharmaceuticals, Inc. (“ARS Pharma”), in accordance with the terms of the agreement and plan of merger and reorganization, dated July 21, 2022, as amended on August 11, 2022 and October 25, 2022 (the “Merger Agreement”), whereby Sabre Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and wholly-owned subsidiary of Silverback, merged into ARS Pharma, with ARS Pharma surviving as Silverback’s wholly-owned subsidiary. ARS Pharma was renamed ARS Subsidiary, Inc. At the completion of the Merger, the prior ARS Pharma equityholders owned 62% and the prior Silverback equityholders owned 38% of the combined company, in each case on a fully diluted basis using the treasury stock method and excluding out-of-money options of Silverback.

The Merger was accounted for as a reverse recapitalization, with ARS Pharma being treated as the acquirer for accounting purposes. Pursuant to the Merger Agreement, Silverback changed its name to ARS Pharmaceuticals, Inc., and changed its corporate ticker symbol on the Nasdaq Global Market to “SPRY”. See discussions of the transactions in connection with the Merger at Note 3- Merger and Related Transactions.

Liquidity and Capital Resources

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. The Company has incurred net operating losses since its inception and had an accumulated deficit of $76.9 million as of December 31, 2022. The Company had cash, cash equivalents, and short-term investments of $274.4 million as of December 31, 2022 and has not generated positive cash flows from operations. To date, the Company has funded its operations primarily with proceeds from the Merger, the issuance of convertible preferred stock, payments earned under collaboration agreements and bank debt. The Company’s currently available cash, cash equivalents, and investments as of December 31, 2022 are sufficient to meet its anticipated cash requirements for at least the 12 months following the date the financial statements are issued.

From August 5, 2015 (inception) through December 31, 2022, the Company has devoted substantially all of its efforts to developing intellectual property and conducting product development and clinical trials, raising capital, and building infrastructure. The Company has a limited operating history, and the sales and income potential of the Company’s business and market are unproven. If the Company does not successfully commercialize any product candidates for which it receives regulatory approval, it will be unable to generate recurring product revenue or achieve profitability. Management expects operating expenses to increase for the foreseeable future and there can be no assurance that the Company will ever achieve profitability, or if achieved, that it will be sustained on a continuing basis.

The novel coronavirus-2019 (“COVID-19”) epidemic and geopolitical events have resulted in a significant disruption of global financial markets. The Company’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and further disruptions to, and volatility in, the credit and financial markets in the United States, including recent bank failures, and worldwide resulting from a resurgence of COVID-19, future health epidemics or pandemics, geopolitical actions or other macroeconomic factors. If such further disruption occurs, the Company could experience an inability to access additional capital. If the Company is not able to secure adequate additional funding, it may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations, and future prospects.

112

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”), of the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of the Company and ARS Pharmaceuticals IRL, Limited for the year ended December 31, 2022. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s functional and reporting currency is the U.S. dollar. Assets and liabilities that are not denominated in the functional currency are remeasured into U.S. dollars at foreign currency exchange rates in effect at the balance sheet date except for nonmonetary assets, which are remeasured at historical foreign currency exchange rates in effect at the date of transaction. Net realized and unrealized gains and losses from foreign currency transactions and remeasurement are reported in other income (expense) in the consolidated statements of operations and comprehensive loss. All adjustments considered necessary for a fair presentation have been included.

Since ARS Pharma was determined to be the accounting acquirer in connection with the Merger, for periods prior to the Merger the consolidated financial statements were prepared on a stand-alone basis for ARS Pharma and did not include the combined entities activity or financial position. Subsequent to the Merger, the consolidated financial statements as of and for the year ended December 31, 2022 include Silverback’s activity and Silverback’s assets and liabilities at their acquisition date fair value. Historical share and per share figures of ARS Pharma have been retroactively restated based on the exchange ratio of 1.1819.

Use of Estimates

The preparation of the Company’s consolidated financial statements requires it to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in the Company’s consolidated financial statements and accompanying notes. The most significant estimates in the Company’s consolidated financial statements relate to revenue recognized for its collaboration agreements, accruals for research and development expenses and valuation of equity awards. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue and expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Cash and Cash Equivalents

Cash and cash equivalents include cash readily available in checking, money market and sweep accounts. The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Investments

The Company invests excess cash in investment grade intermediate-term fixed income securities. These investments are included in short-term investments on the balance sheets, classified as available-for-sale, and reported at fair value with unrealized gains and losses included in accumulated other comprehensive loss. Realized gains and losses on the sale of these securities are recognized in net loss.

Fair Value of Financial Instruments

Cash and cash equivalents and investments are carried at fair value. The carrying amounts of all prepaid expenses and other current assets, accounts payable, accrued liabilities, and contract liability, are considered to be representative of their respective fair values because of the short-term nature of those instruments.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and limits its exposure to cash risk by placing its cash with high credit quality financial institutions.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally five years. Repairs and maintenance costs are charged to expense as incurred.

113

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment. The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value 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 asset or asset group are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds its fair value. The Company has not recognized any impairment losses from inception through December 31, 2022.

Leases

Effective January 1, 2021, the Company early adopted ASC No. 2016-02, Leases(Topic 842) (“ASC 842”), which supersedes the current accounting for leases, using the modified retrospective transition method. The Company has elected to apply the practical expedients allowed by the standard for existing leases. The new standard, while retaining two distinct types of leases, finance and operating, (i) requires lessees to record a right-of-use (“ROU”) asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting, (ii) eliminates current real estate specific lease provisions, (iii) modifies the lease classification criteria and (iv) aligns many of the underlying lessor model principles with those in the new revenue standard. The Company determines the initial classification and measurement of its ROU asset and lease liabilities at the lease commencement date and thereafter, if modified. The Company recognizes a ROU asset for its operating leases with lease terms greater than 12 months. The lease term includes any renewal options and termination options that the Company is reasonably assured to exercise. The lease liability is calculated by using the present value of all lease payments, with the present value determined by using the incremental borrowing rate for operating leases determined by using the incremental borrowing rate of interest that the Company would pay to borrow on a collateralized basis an amount equal to the lease payments in a similar economic environment as well as a review of peer companies. Variable charges for common area maintenance and other variable costs are recognized as expense as incurred. Rent expense for operating leases is recognized on a straight-line basis over the reasonably assured lease term based on the total lease payments and is included in research and development and general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Warrant Liability

The Company has issued freestanding warrants to purchase shares of its Series C convertible preferred stock. Prior to the Merger, the Company adjusted the carrying value of such Series C convertible preferred stock warrants to the estimated fair value at each reporting date, with any related increases or decreases in the fair value being recorded within other income (expense) in the consolidated statements of operations and comprehensive loss. Pursuant to the Merger Agreement the Series C convertible preferred stock warrants became warrants to purchase shares of the combined company's common stock. As a result of the Merger, the warrants no longer meet the requirements for liability accounting, as such, the Company adjusted the value of the warrants to the estimated fair value as of the Merger date and reclassified them to equity.

Revenue Recognition

Our revenues generally consist of licenses and research services under license and collaboration agreements. We recognize revenue when we transfer promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) we satisfy the performance obligation(s). At contract inception, we assess the goods or services promised within each contract, assess whether each promised good or service is distinct and identify those that are performance obligations. We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Research and Development Costs

Research and development are expensed in the period incurred. Research and development costs primarily consist of salaries and related expenses for personnel, stock-based compensation expense, external research and development costs incurred under agreements with contract research organizations, investigative sites and consultants to conduct our clinical studies, costs related to compliance with regulatory requirements, costs related to manufacturing the Company’s product candidates for clinical trials and other allocated expenses.

114

Payments for research and development activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of performance are reflected in the accompanying consolidated balance sheets as prepaid expenses. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. The Company uses judgments and estimates to determine the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates.

Patent Costs

Costs related to filing and pursuing patent applications are recorded as general and administrative expenses in the statements of operations and expensed as incurred since recoverability of such expenditures is uncertain.

License Fees

Costs incurred to acquire technology licenses and milestone payments made on existing agreements are charged to research and development expense or capitalized based upon the asset achieving technological feasibility in accordance with management’s assessment regarding the ultimate recoverability of the amounts paid and the potential for alternative future use.

Stock-Based Compensation

Stock-based compensation expense represents the cost of the grant date fair value of stock option grants recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. The Company recognizes expense for awards subject to performance-based milestones over the remaining service period when management determines that achievement of the milestone is probable. Management evaluates when the achievement of a performance-based milestone is probable based on the expected satisfaction of the performance conditions at each reporting date. The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model and recognizes forfeitures as they occur.

The Company’s equity incentive plans allow for the issuance of restricted stock awards that may be subject to vesting. The unvested shares of any restricted stock awards are held in escrow as the stock award vests or until the holder’s termination of services, whichever occurs first. In the event the holder’s services terminate, the Company has the right of repurchase, at its option, the portion of unvested stock awards. For all early exercised unvested stock awards, a liability is established related to the cash received for the unvested portion of the stock award, which represents the Company’s repurchase rights if the award holders were to be terminated and their stock repurchased.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions on the basis of a two-step process whereby (1) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability.

Comprehensive Loss

Comprehensive loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. The Company’s comprehensive loss was the same as its reported net loss for all periods presented.

115

Segment Reporting

Operating segments are components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker for purposes of making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one operating segment.

Net Loss Per Common Share

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, without consideration of potentially dilutive securities. Diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders since the effect of potentially dilutive securities is anti-dilutive given the net loss of the Company. For purposes of this calculation, convertible preferred stock, stock options, and preferred stock warrants are considered to be common stock equivalents but are not included in the calculations of diluted net loss per share for the periods presented as their effect would be antidilutive.

The following securities are excluded from the calculation of weighted-average dilutive common shares because their inclusion would have been anti-dilutive. Historical share figures have been retroactively restated based on the exchange ratio of 1.1819.

Warrants to purchase convertible preferred stock — 45,456

Warrants to purchase common stock 45,456 —

Recently Issued Accounting Pronouncements — Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. This update is effective for the Company beginning January 1, 2023. The Company is currently evaluating the impact the standard may have on its financial statements and related disclosures.

3. Merger and Related Transactions

As described in Note 1- Nature of Business, ARS Pharma merged with Silverback on November 8, 2022. The Merger was accounted for as a reverse recapitalization under U.S. GAAP. ARS Pharma was considered the accounting acquirer for financial reporting purposes. This determination was based on the facts that, immediately following the Merger: (i) ARS Pharma stockholders own a substantial majority of the voting rights of the combined organization; (ii) ARS Pharma has designated a majority (eight of eleven) of the initial members of the board of directors of the combined organization; and (iii) ARS Pharma’s senior management holds all key positions in senior management of the combined organization. The transaction was accounted for as a reverse recapitalization because on the effective date of the Merger, the pre-combination assets of Silverback were primarily cash and other non-operating assets. Additionally, the Company concluded that the in-process research and development (“IPR&D”) assets that remained as of the combination were not significant when compared to the cash and investments obtained through the transaction.

Under reverse recapitalization accounting, the assets and liabilities of Silverback were recorded at their fair value which approximated book value due to the short-term nature of the instruments. No goodwill or intangible assets were recognized. Consequently, the Company's consolidated financial statements reflect the issuance of 36,535,541 shares to the former stockholders of Silverback.

Under the terms of the Merger Agreement, immediately prior to the effective time of the Merger, each share of ARS Pharma’s preferred stock was converted into a share of ARS Pharma’s common stock.

116

As the accounting acquirer, ARS Pharma is deemed to have assumed all of Silverback’s outstanding and unexercised stock options. The assumed options continue to be governed by the terms of the 2016 and 2020 Equity Incentive Plans of Silverback (as discussed more in Note 10- Stock-Based Compensation) under which the options were originally granted.

As part of the reverse recapitalization, ARS Pharma obtained $262.3 million in cash, cash equivalents and short-term investments, net of transaction costs. ARS Pharma also obtained prepaids and other current assets of approximately $4.4 million and assumed payables and accruals of approximately $12.0 million. ARS Pharma also obtained $1.1 million in IPR&D assets that have no alternative future use. The fair value attributable to these assets was recorded as research and development expense in the Company’s consolidated statement of operations and comprehensive loss for the year ended December 31, 2022. ARS Pharma also incurred transaction costs of approximately $2.1 million and this amount is recorded as a reduction to additional paid-in capital in the accompanying consolidated statement of convertible preferred stock and stockholders’ equity (deficit) for the year ended December 31, 2022.

4. Fair Value Measurements

The Company categorizes its assets and liabilities measured at fair value in accordance with the authoritative accounting guidance that establishes a consistent framework for measuring fair value and expands disclosures for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as the 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 guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

In 2021, based on the borrowing rates currently available to the Company for loans with similar terms, management believe the fair value of the note payable approximates its carrying value. In 2022, the note payable was fully paid off.

The following table identifies the Company’s assets that were measured at fair value on a recurring basis (in thousands):

Short-term investments - U.S. Treasury securities 1 63,456 407 — 63,863

There were no transfers between the Level 1 and Level 2 categories or into or out of the Level 3 category during the periods presented.

The Company’s short-term investments portfolio contains investments in U.S. Treasury securities that have an effective maturity date that is less than one year from the respective balance sheet date. As of December 31, 2022, the Company did not have any investments in an unrealized loss position.

117

As of December 31, 2022, the Company did not have any liabilities that were measured at fair value on a recurring basis. As a result of the Merger, the preferred stock warrant liability that was outstanding was remeasured as of the Merger date and reclassified to equity. During 2022, the Company recorded total other expense relating to this warrant of $0.1 million. There were no transfers between the Level 1 and Level 2 categories or into or out of the Level 3 category during the periods presented.

6. Collaboration and Out-Licensing

The Company has entered into collaboration and licensing agreements to license certain rights to neffy to third parties. The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, up-front license fees; clinical, regulatory, and/or commercial milestone payments; payment for clinical and commercial supply and royalties or a transfer price on the net sales of licensed products.

Licenses of Intellectual Property. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, revenue is recognized from non-refundable, up-front payments allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. If the license is not a distinct performance obligation, the Company evaluates 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, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

118

Milestone Payments. At the inception of each arrangement that includes clinical, regulatory or commercial milestone payments, the Company evaluates whether achieving the milestones 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. Milestone payments that are not within the Company’s control, such as approvals from regulators or where attainment of the specified event is dependent on the development activities of a third party, are not considered probable of being achieved until those approvals are received or the specified event occurs. Revenue is recognized when the underlying performance obligation has been transferred to the customer.

Research and Development Revenues. For arrangements that contain research and development commitments, any arrangement consideration allocated to the research and development work is recognized as the underlying services are performed over the research and development term.

Clinical and Commercial Supply. Arrangements that include a promise for the future supply of drug product for either clinical development or commercial supply at the licensee’s discretion are generally considered as options. We assess if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations. The Company has not earned revenues for clinical or commercial supply sales as of December 31, 2022.

Royalty/Transfer Price Revenues. For arrangements that include sales-based royalties or transfer price, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). The Company has not received any royalty or transfer price revenues as of December 31, 2022.

Alfresa Agreement

In March 2020, the Company signed a Letter of Intent (“LOI”) with Alfresa Pharma Corporation (“Alfresa”) for the right to negotiate a definitive agreement for the exclusive license and sublicensable right to develop, register, import, manufacture and commercialize neffy in Japan in exchange for an upfront payment of $2.0 million. In April 2020, the Company entered into a Collaboration and License Agreement for the rights pursuant to the LOI. Under the agreement, the Company delivered a license to the neffy technology and is responsible for completion of a certain clinical study and for the manufacturing of development and commercial drug supply. The parties agreed to share the cost of any additional clinical studies required for approval of neffy in Japan. Alfresa is solely responsible for regulatory and commercialization activities and may elect to assume responsibility for manufacturing and supplying drug product for commercial use in Japan. Either party may terminate the agreement for certain breaches of the agreement. Unless terminated earlier by either or both parties, the term of the agreement will continue until the later of (i) expiration of the last-to-expire patent in Japan; or (ii) 10 years after the commercial sale of neffy in Japan.

In addition to the $2.0 million received under the LOI, the Company is eligible to receive up to $13.0 million of milestone payments upon achievement of certain clinical and regulatory milestones. Further, the Company is eligible to receive a negotiable transfer price expected to be in the low double-digit percentage on net sales subject to the regulatory approval to commercialize neffy in Japan. In July 2020, the Company earned a $5.0 million milestone payment upon the completion of a clinical milestone in Japan.

At the commencement of this collaboration, the Company identified the following performance obligations: the license for neffy and research and development services. The Company determined the initial transaction price to be the $7.0 million, which includes a clinical milestone as it was deemed not probable of significant reversal at the inception of the agreement. Due to the uncertainty in the achievement of the regulatory and commercial milestones, the variable consideration associated with these future milestone payments has been fully constrained and is excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be re-assessed at each reporting period. The transaction price was allocated to the performance obligations based on the estimated stand-alone selling price of each performance obligation. The Company recognized revenue of $0.1 million and $0.2 million for the years ended December 31, 2022 and 2021, respectively and had a contract liability of an immaterial amount and $0.1 million as of December 31, 2022 and 2021, respectively.

Recordati Agreement

In September 2020, the Company entered into a License and Supply Agreement (the “Recordati Agreement”) with Recordati Ireland, Ltd. (“Recordati”) for the exclusive license and sublicensable right to develop, import, manufacture or have manufactured commercial product, file and hold regulatory approvals and commercialize neffy in Europe and certain European Free Trade Association, Russia/the Commonwealth of Independent States, Middle East and African countries (the “Recordati Territory”). Under the Recordati Agreement, the Company is responsible for completion of any clinical studies for neffy required by the European Medicines Agency (“EMA”) before granting European Union Marketing Authorization, and by the Medicines and Healthcare products Regulatory Agency (“MHRA”) prior to granting United Kingdom Marketing Authorization. The Company filed the initial regulatory submissions with the EMA in the fourth quarter of 2022 and will file the initial regulatory submissions with the MHRA for neffy and is responsible for the manufacturing of commercial supply. Recordati is solely responsible all regulatory activities in the region after the Company’s initial regulatory submissions to the EMA and MHRA, for any post-approval clinical studies and commercialization activities. Either party may terminate the Recordati Agreement for certain breaches. Unless terminated earlier by either or both parties, the term of the Recordati Agreement will continue as long as Recordati has commercial sales of neffy in the region.

Under the terms of the Recordati Agreement, the Company received an upfront payment of $11.8 million and a regulatory milestone payment of $6.0 million during 2020. In addition, the Company is eligible to receive up to 90.0 million euros of milestone payments upon achievement of certain regulatory and commercial sales milestones. Subject to regulatory approval, the Company will earn tiered royalties in the low double-digits on annual net sales in the region and will receive a per unit supply price for the sale of commercial supply to Recordati. The per unit commercial supply costs are subject to a cap. The combined tiered royalty and supply price have a low double-digit cap.

At the commencement of this collaboration, the Company identified the following performance obligations: the license for neffy in the defined territory and the research and development services. The Company determined the initial transaction price to be the $11.8 million. Due to the uncertainty in the achievement of all the developmental and commercial milestones, at inception of the contract, the variable consideration associated with future milestone payments was fully constrained and excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be re-assessed at each reporting period. The transaction price was allocated to the performance obligations based on the estimated stand-alone selling price of each performance obligation. In November 2020, the Company earned a regulatory milestone of $6.0 million. The Company recognized revenue of $1.2 million and $2.3 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022 and 2021, there was a contract liability of $3.1 million and $4.4 million, respectively.

On February 22, 2023, the Company and Recordati entered into a termination agreement (the “Termination Agreement”), pursuant to which, among other things, the Company and Recordati agreed to terminate the Recordati Agreement and the Company will reacquire all of the Recordati’s rights under the Recordati Agreement,as described in Note 14- Subsequent Events.

Pediatrix Agreement

In March 2021, the Company entered into a Collaboration and Distribution Agreement with Pediatrix Therapeutics, Inc. (“Pediatrix”) for the exclusive license and sublicensable right to develop, import, manufacture or have manufactured commercial product, file and hold regulatory approvals and commercialize neffy in the People’s Republic of China, Taiwan, Macau, and Hong Kong. Under the agreement, Pediatrix is responsible, at its sole cost and expense, for all ongoing development work that is necessary for or otherwise supports regulatory approval in the defined territory, including all clinical trials, and activities related to post approval commitments and commercialization tests. In addition, Pediatrix is responsible for commercialization activities and may elect to assume responsibility for manufacturing and supplying drug product for commercial use. The Company is responsible for the manufacturing of product for clinical studies as well as commercial supply, all at a negotiated transfer price. Either party may terminate the agreement for certain breaches of the agreement. Unless terminated earlier by either or both parties, the term of the agreement will continue as long as Pediatrix has commercial sales of neffy in the region, or 10 years after the first commercial sale.

Under the terms of the agreement, the Company received an upfront payment of $3.0 million. In addition, the Company is eligible to receive up to $84.0 million of milestone payments upon achievement of certain regulatory and commercial sales milestones. Subject to regulatory approval, the Company will earn tiered royalties in the low double-digits on annual net sales in the region and will receive a per unit supply price for the sale of commercial supply to Pediatrix.

120

At the commencement of this collaboration, the Company identified performance obligations related to the delivery of the license for neffy in the defined territory and manufacturing of product for clinical studies and commercial supply. The Company concluded that the license was distinct from potential supply obligation. The supply provisions are effectively options granted to Pediatrix to purchase future goods and would only constitute a performance obligation if they contain a material right. The Company determined the option to purchase the clinical and commercial supply was not at a significantly discounted price and does not represent a material right, therefore does not constitute a performance obligation. The Company determined the initial transaction price to be the $3.0 million. Due to the uncertainty in the achievement of all the developmental and commercial milestones, the variable consideration associated with these future milestone payments has been fully constrained and is excluded from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be re-assessed at each reporting period. The Company recognized revenue of the full $3.0 million during the year ended December 31, 2021.

A reconciliation of contract liability from collaboration agreements was as follows (in thousands):

Revenue recognized (1,316 )

7. Commitments and Contingencies

Note Payable

In September 2019, the Company entered into a Loan and Security Agreement (“Loan Agreement”) with Silicon Valley Bank for working capital in the principal amount, as amended, of $10.0 million (the “Note”). The Note required interest only payments through June 30, 2021 and had a maturity date of March 1, 2024. In addition, there was a final payment (“Balloon Payment”) of $0.3 million at maturity.

In connection with the Note, the lender received warrants to purchase 38,460 shares of Series C convertible preferred stock at $2.60 per share. The warrants were immediately exercisable and will expire on September 30, 2029. The estimated fair value of the warrants at issuance was $86,000 which was recorded as a debt discount. In addition, the Company recorded debt issuance costs totaling $47,000.

The debt discount, debt issuance costs and Balloon Payment were amortized to interest expense using the effective interest rate method over the loan term. The Company recognized interest expense of $0.6 million and $0.8 million for the years ended December 31, 2022 and 2021, respectively, and debt discount amortization of $0.3 million and $0.2 million for the years ended December 31, 2022 and 2021, respectively.

On November 7, 2022, the Company paid off the remaining balance of $5.4 million on its loans with Silicon Valley Bank, including all principal and interest and the Balloon Payment. The warrants issued to Silicon Valley Bank in connection with the loans continue to be outstanding.

Leases

In October 2021, the Company entered into a 38-month noncancelable lease for its current headquarters location consisting of 4,047 rentable square feet of office space in San Diego, California. Under the terms of the agreement, there is no option to extend the lease, and the Company is subject to additional charges for common area maintenance and other costs. Monthly rental payments due under the lease commenced on December 6, 2021 and escalate through the lease term. The Company prepaid the first month’s rent upon execution of the lease, and the lease agreement provided full rent abatement for the second and third months of the rental term. As of December 31, 2022, the remaining lease term of the Company’s operating lease was 26 months, and the discount rate on the Company’s operating lease was 8%. As there was not an implicit rate within the lease, the discount rate was determined by using a set of peer companies incremental borrowing rates. The Company's operating lease expense was $0.2 million and immaterial for the years ended December 31, 2022 and 2021, respectively. The Company's variable lease expense was $0.1 million and immaterial for the years ended December 31, 2022 and 2021, respectively. Cash paid for amounts included in the measurement of lease liabilities was $0.2 million and zero for the years ended December 31, 2022 and 2021, respectively.

Contingencies

From time to time, the Company may be involved in various legal proceedings and subject to claims that arise in the ordinary course of business.

On August 12, 2021, Amphastar Pharmaceuticals, Inc. (“Amphastar”) filed a Petition for Inter Partes Review (“IPR”) with the United States Patent and Trademark Office (“USPTO”), seeking to invalidate claims 1-20 of United States Patent No. 10,682,414 (the “‘414 patent”). The ‘414 patent issued on June 16, 2020 and is entitled “Intranasal Epinephrine Formulations and Methods for the Treatment of Disease.” The claims of the ‘414 patent are directed to methods of treating a type-1 hypersensitivity reaction, including anaphylaxis, using an aqueous nasal spray pharmaceutical formulation containing epinephrine or a salt thereof, including the Company’s neffy product candidate, in a single dose. On February 9, 2023, the USPTO issued a Final Written Decision finding claims 3-6 and 18-20, which encompass the Company’s neffy product candidate, patentable, and claims 1-2 and 7-17 unpatentable. Both the Company and Amphastar have the right to file a motion for reconsideration with the USPTO in addition to a notice of appeal with the United States Court of Appeals for the Federal Circuit. Although the results of any motion for reconsideration or notice of appeal are inherently unpredictable and uncertain, and could result in either the USPTO or the Federal Circuit finding some or all of claims 1-20 of the ‘414 patent to be invalid or unenforceable, the Company does not believe that an adverse outcome will have a material adverse effect on its business, operating results, cash flows or financial condition.

On November 5, 2021, a securities class action complaint was filed against Silverback and certain of Silverback’s former officers and directors in the U.S. District for the Western District of Washington, captioned Dresner v. Silverback Therapeutics, Inc., et al., Case No. 2:21-cv-01499 (the “Dresner Case”). The court has appointed lead plaintiff and lead plaintiff's counsel, and plaintiff's counsel then filed the amended complaint on April 11, 2022. The amended complaint alleges that between December 3, 2020 and March 31, 2022, Silverback and certain of its officers and directors violated (1) Sections 11 and 15 of the Securities Act of 1933, as amended; and (2) Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Securities and Exchange Commission (“SEC”) Rule 10b-5 promulgated thereunder, by making allegedly false and misleading statements in various SEC filings and press releases regarding the clinical and commercial prospects of its product candidate, SBT6050, which is now discontinued. The complaint seeks unspecified damages and interest, as well as attorneys’ fees and other costs. Silverback and the other defendants filed a motion to dismiss on May 26, 2022 and lead plaintiff filed an opposition brief on July 11, 2022. On August 10, 2022, Silverback and the other defendants filed a reply brief. The court held a hearing on October 28, 2022 and issued an order granting defendants’ motion to dismiss without prejudice on November 4, 2022. Plaintiffs were given leave to amend and filed a Second Amended Complaint (“SAC”) on December 5, 2022, which asserted Section 11 claims only with respect to Silverback’s December 3, 2020 IPO and Section 10(b) claims during a shorter class period of March 29, 2021 through March 31, 2022. Defendants filed a motion to dismiss the SAC on January 2, 2023. Lead plaintiff filed an opposition brief on January 23, 2023, and defendants filed a reply brief January 27, 2023. The court is expected to issue a ruling on the motion to dismiss in the first half of 2023.

Regardless of the outcome, involvement in legal proceedings may have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. The Company cannot predict the outcome of these suits, and failure by the Company to obtain favorable resolutions could have a material adverse effect on its business, results of operations, and financial condition. The Company’s chances of success on the merits of either of these suits are still uncertain and any possible loss or range of loss cannot be reasonably estimated and as such the Company has not recorded a liability as of December 31, 2022.

Except as described above, the Company is not currently involved in any legal proceeding that it believes could have a materially adverse effect on its financial condition or results of operations. Except as described above, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or other body pending or, to the knowledge of the Company’s executive officers, threatened against or affecting the Company, the Company’s common stock, any of its subsidiaries or its subsidiaries’ officers or directors in their capacities as such, in which an adverse decision could have a material adverse effect.

8. In-Licensing and Supply

License Agreement with Aegis

In June 2018, the Company entered into a License Agreement (the “Aegis Agreement”) with Aegis Therapeutics, LLC (“Aegis”). Under the Aegis Agreement, the Company licensed the exclusive, worldwide, royalty-bearing, sublicensable, rights to certain proprietary Aegis technology, patent rights and know-how to develop and commercialize epinephrine products. The Company utilizes this technology for the development of its lead product candidate, neffy. As consideration for the license, the Company paid an upfront license fee of $50,000, which was recorded in research and development expenses in the consolidated statement of operations.

The Company is required to make aggregate milestone payments of up to $20.0 million upon achievement of certain regulatory and commercial milestones. The regulatory milestone payments under the Aegis Agreement will be recognized as research and development expense upon completion of the required events, as the triggering events are not considered to be probable until they are achieved. The Company made a $0.5 million milestone payment to Aegis upon the achievement of a regulatory milestone during 2019, and a $1.0 million payment to Aegis upon the FDA’s acceptance of the Company’s New Drug Application (“NDA”) submission for neffy, which occurred in the third quarter of 2022. The Company may be required to pay royalties based on annual net product sales in the low to mid-single digits on its or its sublicensees’ net sales of the Licensed Products (as defined in the Aegis Agreement) on a country-by-country and product-by-product basis.

The Company is responsible for reimbursing Aegis for patent costs incurred in connection with prosecuting and maintaining patent rights that are specific to epinephrine or epinephrine products. There were no expenses recognized in connection with legal patent fees for the years ended December 31, 2022 and 2021.

The Company may terminate the Aegis Agreement with 30 days written notice or either party may terminate the Aegis Agreement for certain breaches of the Aegis Agreement. Unless terminated earlier by either or both parties, the term of the Aegis Agreement will continue until the final expiration of all royalty obligations under the Aegis Agreement.

In conjunction with the Aegis Agreement, the Company also entered into a Supply Agreement (the “Supply Agreement”) with Aegis that allows the Company to purchase materials for preclinical, development and commercial use at predetermined prices. The Company may elect to have Aegis supply minimum quantities but there are no minimum or maximum purchase obligations under the Supply Agreement unless this election is made. The parties may terminate the Supply Agreement at any time by mutual agreement. In addition, the parties may terminate the Supply Agreement in the event of certain breaches of the Supply Agreement or upon the earlier of the expiration or termination of the Aegis Agreement or June 2028. The Supply Agreement term may be extended by mutual written agreement. Expense recognized under the Supply Agreement was $1.0 million and $0.2 million for the years ended December 31, 2022 and 2021, respectively.

Manufacturing Agreement with Renaissance

In September 2020, the Company entered into a manufacturing agreement (the “Renaissance Agreement”) with Renaissance Lakewood, LLC (“Renaissance”). Pursuant to the Renaissance Agreement, Renaissance agreed to manufacture for, and provide to the Company, neffy nasal unit dose sprays (“Renaissance Products”). The Company is obligated to provide Renaissance with certain supplies to manufacture the Renaissance Products and to purchase from Renaissance a mid double-digit percentage of the Company’s annual aggregate Renaissance Product requirements in the E.U., and a high double-digit percentage of the Company’s annual aggregate Renaissance Product requirements in the U.S. The Renaissance Agreement contains conventional commercial pharmaceutical manufacturing provisions including certain minimum purchase amounts to be determined in the future based on forecast needs and minimum batch size projections. The Company may also request Renaissance to perform certain services related to the Renaissance Product, for which the Company will pay reasonable compensation to Renaissance.

123

The initial term of the Renaissance Agreement commenced on September 9, 2020 and continues (a) for Renaissance Product designated for commercial sale in the U.S. until the earlier of the fifth anniversary of the (i) target U.S. launch date and (ii) the initial U.S. launch date (“U.S. Initial Term”), and (b) for Renaissance Product designated for commercial sale in the E.U. and other countries, the earlier of the fifth anniversary of (i) the target E.U. launch date and (ii) the initial E.U. launch date (“E.U. Initial Term”), in each case unless earlier terminated by one of the parties. The U.S. Initial Term and E.U. Initial Term automatically renew for successive two-year terms (“Renewal Term”). Either party may elect not to renew the U.S. Renewal Term and/or the E.U. Renewal Term by providing the requisite prior notice to the other party. Either party may terminate the Renaissance Agreement (1) for uncured material breach of the other party, (2) upon notice for insolvency-related events of the other party that are not discharged within a defined time period, (3) on a product-by-product basis if the manufacture, distribution or sale would materially contravene any applicable law, (4) by providing the requisite notice if (a) the Company has not submitted a regulatory filing for any Renaissance Product in the U.S. on or before June 30, 2022, (b) the authorization and approval to distribute or sell Renaissance Product in the U.S. is not granted on or before the target U.S. launch date, (c) the authorization and approval representing more than a targeted number of units of Renaissance Product sold in the U.S. during the last calendar year is withdrawn by the FDA, or (d) the Company decided in its sole discretion to cease commercializing the Renaissance Product in the U.S., (5) in the case of a force majeure event that continues for six months or more, or (6) a violation by the other party of trade control or anti-corruption laws. Expense recognized under the Renaissance Agreement was $2.0 million and $3.1 million for the years ended December 31, 2022 and 2021, respectively.

10. Stock-Based Compensation

Stock-based compensation expense recognized for all equity awards has been reported in the consolidated statements of operations and comprehensive loss as follows (in thousands):

Years Ended December 31,

Research and development expense $ 213 $ 2,114

General and administrative expense 5,630 715

Total stock-based compensation expense $ 5,843 $ 2,829

As of December 31, 2022, the total unrecognized stock-based compensation expense was $4.6 million, which is expected to be recognized over a remaining weighted-average period of approximately 2.48 years.

For the year ended December 31, 2022, ARS Pharma recognized $1.3 million in stock-based compensation expense for 236,380 performance-based options that vested upon the closing of the Merger. For the year ended December 31, 2021, no performance-based stock-based compensation was recognized.

In connection with the Merger, the Company replaced (only for accounting purposes) 6,599,068 stock options and 493,456 restricted stock units held by Silverback employees and directors. The replacement awards were revalued at their acquisition-date fair value and then attributed to pre and post-combination service. This resulted in $3.1 million in expense attributed to post-combination service to be recognized as compensation cost by the Company, of which $3.0 million has been recognized in general and administrative expense in the accompanying consolidated statements of operations for the year ended December 31, 2022. 482,805 replaced restricted stock units vested in connection with the Merger and the remaining 10,651 are outstanding as of December 31, 2022.

Equity Incentive Plans

In September 2018, ARS Pharma adopted the 2018 Equity Incentive Plan. As a result of the Merger, on November 8, 2022 ARS Pharma, as the accounting acquirer, is deemed to have assumed Silverback's 2016 and 2020 Equity Incentive Plans, and Employee Stock Purchase Plan (“ESPP”). For the year ended December 31, 2022, ESPP activity is not material to the consolidated financial statements.

As of December 31, 2022, the 2016 and 2020 Equity Incentive Plans authorized a total of 11,321,495 shares, of which 3,079,688 shares are available for future grant, and 6,439,311 shares are outstanding. As of December 31, 2022, the 2018 Equity Incentive Plan authorized a total of 6,634,333 shares, of which 294,113 shares are available for future grant, and 5,634,900 shares are outstanding. The Company does not intend to grant future stock options or other equity awards under the 2018 Equity Incentive Plan.

Stock Options

Stock options granted under the Company’s equity incentive plans expire no later than 10 years from the date of grant and generally vest over a four-year period, with vesting either occurring at a rate of 25% at the end of the first year and thereafter in 36 equal monthly installments or on a monthly basis. In the case of awards granted to our non-employee board members, vesting generally occurs on a monthly basis over three years or in full on an annual basis. The Company issues new shares of common stock upon the exercise of stock options.

125

A summary of the Company’s stock option activity for the year ended December 31, 2022 is as follows:

The exercisable shares subject to options outstanding at December 31, 2022 in the table above include vested and early exercisable awards. The aggregate intrinsic value in the table above is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the Company’s common stock for all options that were in-the-money at December 31, 2022.The aggregate intrinsic value of options exercised during the years ended December 31, 2022 and 2021 was $1.2 million and $0.1 million, respectively.

The weighted-average grant date fair value per share of option grants for the years ended December 31, 2022 and 2021 was $1.50 and $0.97, respectively. The total fair value of shares vested during the years ended December 31, 2022 and 2021 was $2.7 million and $0.4 million, respectively.

The fair value of stock options granted or assumed in connection with the Merger was estimated using a Black-Scholes option-pricing model (“Black-Scholes”) with the following weighted-average assumptions:

Assumed on Years Ended December 31,

Expected term (in years) 0.8 6.1 6.0

Risk-free interest rate 4.5 % 2.1 % 1.2 %

Expected dividend yield — — —

126

The fair value of stock options was determined using the Black-Scholes assumptions below. Each of these inputs is subjective and generally requires significant judgement.

11. Income Taxes

A reconciliation of the federal statutory income tax rate to the Company’s effective tax rate is as follows (in thousands):

Years Ended December 31,

Tax computed at federal statutory rate $ (7,283 ) $ (4,251 )

State income taxes, net of federal benefit (21 ) (9 )

Research and development credits (624 ) (1,120 )

Provision for income taxes $ — $ —

127

Significant components of the Company’s net deferred tax assets were as follows (in thousands):

Years Ended December 31,

Deferred tax assets:

Research and development credits 2,964 2,340

Deferred tax liabilities:

Total deferred liabilities (249 ) (141 )

Net deferred tax assets $ — $ —

The Company has established a valuation allowance against net deferred tax assets due to the uncertainty that such assets will be realized. The Company periodically evaluates the recoverability of the deferred assets. At such time as it is determined that it is more likely than not that the deferred tax asset will be realized, the valuation allowance will be reduced. The change in the valuation allowance for the year ended December 31, 2022 was an increase of $8.6 million.

At December 31, 2022, the Company had federal and state net operating loss carryforwards (“NOL”) of $38.9 million and $7.2 million, respectively. Federal NOL carryforwards of $38.9 million, generated after 2017, may be carryforward indefinitely but can only be utilized to offset 80% of future taxable income. The state NOL carryforwards begin expiring in 2036. State NOLs totaling $1.6 million may be carried forward indefinitely. In addition, the Company also has federal and California research and development credit carryforwards totaling $3.4 million and $0.7 million, respectively. The federal research and development credit carryforwards will begin to expire in 2035 unless previously utilized. The California research credits do not expire. The NOL and credit carryovers noted above do not include the pre-Merger amounts attributable to Silverback as noted in the IRC Section 382 disclosure in the paragraph below.

Pursuant to Internal Revenue Code (“IRC”) Sections 382 and 383, annual use of the company's NOL and research and development credit carryforwards may be limited in the event a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has not completed an ownership change analysis pursuant to IRC Section 382. If ownership changes have occurred or occurs in the future, the amount of remaining tax attribute carryforwards available to offset taxable income and income tax expense in future years may be restricted or eliminated. If eliminated, the related asset would be removed from deferred tax assets with a corresponding reduction in the valuation allowance. Due to the existence of the valuation allowance, limitations created by future ownership changes, if any, will not impact the Company’s effective tax rate.

Additionally, as part of the transaction with Silverback, certain deferred tax assets generated in the Silverback pre-Merger periods were acquired by the Company consisting of federal and state net operation loss carryovers, research tax credit carryovers, and other tax attributes. These deferred tax assets will be subject to limitations on future use under IRC Section 382 and some of the attributes may expire unused. The Company has not completed an analysis under IRC Section 382 to determine the amount of such tax attributes that will be available annually and how much, if any, of the tax attributes may expire unused. As a result, the Company has not included any of these deferred tax assets in its components of deferred tax asset in the table above. Once the analysis is complete, to the extent that such deferred tax assets are available for future utilization, such assets will be included in the deferred tax assets and will be fully offset by valuation allowance as of December 31, 2022.

The evaluation of uncertainty in a tax position is a two-step process. The first step involves recognition. The Company determines whether it is more likely than not that a tax position will be sustained upon tax examination, including resolution of any related appeals or litigation, based on only the technical merits of the position. The technical merits of a tax position are derived from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings, and case law) and their applicability to the facts and circumstances of the tax position. If a tax position does not meet the more-likely-than-not recognition threshold, the benefit of that position is not recognized in the financial statements. The second step is measurement. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate resolution with a taxing authority.

The following table summarizes the reconciliation of the unrecognized tax benefits activity during the years ended December 31, 2022 and 2021 (in thousands):

Years Ended December 31,

Unrecognized tax benefits - beginning $ 1,147 $ 941

Gross increase – current-period tax positions 373 206

Unrecognized tax benefits - ending $ 1,520 $ 1,147

The unrecognized tax benefit amounts are reflected in the determination of the Company’s deferred tax assets. If recognized, none of these amounts would affect the Company’s effective tax rate, since it would be offset by an equal corresponding adjustment in the deferred tax asset valuation allowance. The Company does not foresee material changes to its liability for uncertain tax benefits within the next twelve months.

The Company files income tax returns in the United States, various states within the United States, and Ireland. Due to the Company’s losses incurred, the Company’s income tax returns for all jurisdictions are subject to examination by tax authorities from inception. The Company’s policy is to recognize interest expense and penalties related to income tax matters as tax expense. As of December 31, 2022, there were no significant accruals for interest related to unrecognized tax benefits or tax penalties. The Company has not incurred any material interest or penalties as of the current reporting date with respect to income tax matters. The Company does not expect that there will be unrecognized tax benefits of a significant nature that will increase or decrease within 12 months of the reporting date.

12. Employee Benefit Plans

In June 2022, the Company adopted a retirement plan, which is qualified under section 401(k) of the Internal Revenue Code of 1986, as amended, for the Company’s U.S. employees. The plan allows eligible employees to defer, at the employee’s discretion, pretax compensation up to the Internal Revenue Service (the “IRS”) annual limits. The Company matches up to 5% of an employee’s contributions, subject to IRS limitations. Expense associated with the Company’s matching contribution totaled $0.1 million for the year ended December 31, 2022.

13. Related-Party Transactions

In September 2015, the Company entered into a consulting agreement, superseded in July 2022, for regulatory and development services with Pacific-Link Consulting, LLC, an entity owned by the President/Chief Executive Officer/director and the Chief Medical Officer of the Company. The Company incurred consulting expense related to this agreement totaling $2.1 million and $1.1 million during the years ended December 31, 2022 and 2021, respectively.

In September 2018, the Company entered into a consulting agreement with Marlinspike Group, LLC (“Marlinspike Group”) to provide management, business consulting services and business development support. In addition, Marlinspike Group provides the use of its facilities to the Company from time to time. The managing member of Marlinspike Group is the Chair of the Board of Directors of the Company and one of its stockholders. The Company incurred annual expenses related to this agreement totaling $0.2 million for both of the years ended December 31, 2022 and 2021.

In November 2018, the Company entered into a consulting agreement for commercial and marketing consulting services with Red Team Associates, LLC (“Red Team”), an entity controlled by the Executive Vice President of Commercial Strategy of the Company. The Company incurred consulting expense related to this agreement totaling $0.2 million and $0.1 million during the years ended December 31, 2022 and 2021, respectively.

In April 2021, the Company entered into a consulting agreement, as amended in April 2022, with a member of the Board of Directors of the Company for general advice and assistance with the development of its current and future product candidates. As compensation for the consulting services the Company granted the member of the Board of Directors 590,950 stock options that vest over a four-year period. The Company incurred stock-based compensation expense related to this agreement totaling $0.1 million for both of the years ended December 31, 2022 and 2021.

14. Subsequent Events

Termination Agreement

On February 22, 2023, the Company entered into the Termination Agreement with Recordati, pursuant to which, among other things, the Company and Recordati agreed to terminate the Recordati License and Supply Agreement. Pursuant to the Termination Agreement, the Company will reacquire all of the Recordati Rights and has agreed to pay Recordati a one-time upfront payment of €3.0 million and additional payments upon achievement of certain milestones including: (i) an EMA regulatory milestone payment of €2.0 million, (ii) a milestone payment of €5.0 million upon first commercial sale of a Recordati Licensed Product in the Recordati Territory, and (iii) milestone payments of up to €5.0 million in the aggregate from sales of Recordati Licensed Product(s) in the Recordati Territory.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, our management with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term “disclosure controls and procedures” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2022, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 2013 framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2022.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 22 headings are on that chain and 16 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
