Notes to Unaudited Interim Condensed Consolidated Financial Statements

Note 1—Description of the Business and Financial Condition

Angion Biomedica Corp. ("Angion", the "Company" or “we”) is a late-stage biopharmaceutical company focused on the discovery, development and commercialization of novel small molecule therapeutics to address acute organ injuries and fibrotic diseases. The Company was incorporated in Delaware in 1998.

Forward Stock Split

On January 25, 2021, the board of directors of the Company approved an amendment to the Company's certificate of incorporation to effect a forward stock split ("Forward Split") of shares of the Company's common stock on a one-for-1.55583 basis, which was effected on February 1, 2021. All references to common stock, convertible preferred stock, warrants to purchase common stock, stock options, RSAs, RSUs, PSUs, per share amounts and related information contained in the condensed consolidated financial statements have been retroactively adjusted to reflect the effect of the forward stock split for all periods presented. No fractional shares of the Company's common stock were issued in connection with the Forward Split. Any fractional share resulting from the Forward Split was rounded down to the nearest whole share, and any stockholder entitled to fractional shares as a result of the Forward Split will receive a cash payment in lieu of receiving fractional shares.

Initial Public Offering and the Concurrent Private Placement

On February 9, 2021, the Company closed its Initial Public Offering (“IPO”) of 5,750,000 shares of common stock at a public offering price of $16.00 per share, which includes the full exercise by the underwriters of their option to purchase an additional 750,000 shares of common stock. Aggregate net proceeds to Angion were $85.6 million, after deducting underwriting discounts, commissions and offering expenses of $6.4 million. In addition to the shares being sold in the IPO, Angion sold an additional 1,562,500 shares of its common stock at the public offering price of $16.00 per share to entities affiliated with Vifor International, Ltd., an existing stockholder (the “Concurrent Private Placement”), for aggregate net proceeds of $24.3 million, after deducting a 3% private placement agent fee of $0.7 million. Subsequent to the closing of the IPO, all of the outstanding shares of convertible preferred stock and outstanding convertible notes automatically converted into shares of common stock.

Subsequent to the closing of the IPO, there were no shares of convertible preferred stock outstanding and there were no convertible notes outstanding. In connection with the closing of the IPO, the Company restated its Restated Certificate of Incorporation to change the authorized capital stock to 300,000,000 shares designated as common stock, and 10,000,000 shares designated as preferred stock, with a par value of $0.01 per share and $0.01 per share, respectively.

Liquidity and Capital Resources

Since inception, the Company has devoted substantially all of its efforts and financial resources to conducting research and development activities, including drug discovery and pre-clinical studies and clinical trials, establishing and maintaining its intellectual property portfolio, organizing and staffing the Company, business planning, raising capital and providing general and administrative support for these operations. The Company has incurred losses from operations and negative cash flows from operating activities since inception and expects to continue to incur substantial losses for the next several years as it continues to fully develop and, if approved, commercialize its product candidates. As of September 30, 2021, the Company had $102.7 million in cash and cash equivalents and an accumulated deficit of $230.0 million. Prior to its IPO completed in February 2021, the Company has funded its operations through United States government grants, the issuance of convertible notes (see Note 6), sales of convertible preferred stock and common stock (see Notes 7) and warrants (see Note 10) and licensing agreements (see Note 3).

The planned expansion of the Company's clinical and discovery programs will require significant funds. Management expects to continue to incur significant expenses and to incur operating losses for the foreseeable future. The Company believes that its existing cash and cash equivalents will be sufficient to meet the projected operating requirements for at least 12 months from the date of issuance of its financial statements. The Company has evaluated and concluded there are no conditions or events, considered in the aggregate, that raise substantial

Notes to Consolidated Financial Statements (Continued)

doubt about its ability to continue as a going concern for a period of one year following the date these condensed consolidated financial statements are issued.

Note 2—Summary of Significant Accounting Policies

Basis of Presentation

The Company's condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of the Company, its wholly owned subsidiary, Angion Biomedica Europe Limited, which was dissolved on March 16, 2021, and its wholly owned subsidiary, Angion Pty Ltd., which was established on August 22, 2019. The Company established Angion Pty Ltd., an Australian subsidiary, for the purpose of qualifying for research credits for studies conducted in Australia. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company’s remaining significant accounting policies are described in Note 2 to its consolidated financial statements for the year ended December 31, 2020, included in its Annual Report on Form 10-K. There have been no material changes to the Company’s significant accounting policies during the three and nine months ended September 30, 2021.

Unaudited Interim Financial Information

The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The interim unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2020 and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s consolidated financial position, results of operations and comprehensive loss, and cash flows. The condensed consolidated balance sheet as of December 31, 2020 was derived from the audited financial statements as of that date. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this Quarterly Report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K as filed with the SEC on March 30, 2021. The results for any interim period are not necessarily indicative of results for any future period.

Segments

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

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, including those related to the useful lives of long-lived assets, the measurement of stock-based compensation, accruals for research and development activities, income taxes and revenue recognition. The Company bases its estimates on historical experience and on other relevant assumptions that are reasonable under the circumstances. Actual results could materially differ from those estimates.

Concentrations of Credit Risk and Off-Balance Sheet Risk

Cash and cash equivalents are financial instruments that are potentially subject to concentrations of credit risk. The Company's cash and cash equivalents are deposited in accounts at large financial institutions, and amounts

10

Notes to Consolidated Financial Statements (Continued)

may exceed federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash balances due to the financial position of the depository institution in which those deposits are held.

Additionally, the Company established guidelines regarding approved investments and maturities of investments, which are designed to maintain safety and liquidity.

The Company maintains its cash equivalents in securities and money market funds with original maturities less than three months.

The Company has no financial instruments with off-balance sheet risk of loss.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. As of September 30, 2021 and December 31, 2020, the Company’s cash equivalents were held in institutions in the United States and include deposits in a money market fund which were unrestricted as to withdrawal or use.

Deferred Offering Costs

Deferred offering costs consist of legal and accounting fees incurred through the balance sheet date that are directly related to the Company's IPO and have been reflected as issuance costs upon the completion of the offering. As of December 31, 2020, $2.0 million of deferred offering costs were included in prepaid expenses and other current assets in the condensed consolidated balance sheets. Subsequent to the closing of the IPO, $2.8 million of deferred costs previously included in prepaid expenses and other current assets was netted with additional paid in capital in the condensed consolidated balance sheets.

Fair Value Measurement

Certain assets and liabilities are carried at fair value under GAAP. Fair value is determined using the principles of ASC 820, Fair Value Measurement. Fair value is described as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes and defines the inputs to valuation techniques as follows:

Level 1:    Observable inputs such as quoted prices in active markets.

Level 2:    Inputs are observable for the asset or liability either directly or through corroboration with observable market data.

Level 3:    Unobservable inputs.

The inputs used to measure the fair value of an asset or a liability are categorized within levels of the fair value hierarchy. The fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the measurement.

The Company's cash and cash equivalents, accounts payable and accrued expenses are carried at cost, which approximates fair value due to the short-term nature of these instruments.

Convertible Notes Payable at Fair Value

As permitted under ASC 825, Financial Instruments ("ASC 825"), the Company has elected the fair value option for recognition of its convertible notes. In accordance with ASC 825, the Company recognizes these convertible notes at fair value with changes in fair value recognized in the condensed consolidated statements of operations. The fair value option may be applied instrument by instrument, but it is irrevocable. As a result of applying the fair value option, direct costs and fees related to the convertible notes were recognized in general and administrative expense in earnings as incurred and not deferred. The estimated fair value of the convertible notes is determined by utilizing a present value cash flow model and the values of the equity underlying the conversion options were estimated using company equity values implied from the Subject Company Transaction Method which

includes the back-solve and scenario-based methods (Probability Weighted Expected Return Method). See Note 4. Accrued interest for the notes has been included in the change in fair value of convertible notes in the condensed consolidated statements of operations. All outstanding convertible notes were converted into common stock upon the close of the IPO on February 9, 2021 and no balances remained outstanding as of September 30, 2021. See Note 6.

Convertible Preferred Stock

Series C convertible preferred stock includes settlement features that result in liability classification. The initial carrying value of the Series C convertible preferred stock is accreted to the settlement value, the fair value of the securities to be issued upon the conversion of the Series C Preferred Stock. The discount to the settlement value is accreted to interest expense using the effective interest method. During 2020, certain convertible notes were exchanged for Series C convertible preferred stock. As the exchange was accounted for as a modification, the Series C convertible preferred stock that was exchanged for the convertible notes was recorded at fair value and are subject to re-measurement at each reporting period with gains and losses reported through the Company’s condensed consolidated statements of operations. All outstanding shares of convertible preferred stock were converted into common stock upon the close of the Company’s IPO on February 9, 2021. See Note 7. As of September 30, 2021, there was no convertible preferred stock outstanding.

Revenue

The Company does not have any products approved for sale and has not generated any revenue from product sales. The Company’s revenue to date has been primarily derived from government funding consisting of U.S. government grants and contracts and revenue under its license agreements.

Contract Revenue

The Company accounts for revenue earned from contracts with customers under Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC Topic 606"). Under ASC Topic 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC Topic 606, the Company performs the following five steps:     

(1)    Identify the contract(s) with a customer;

(2)    Identify the performance obligations in the contract;

(3)    Determine the transaction price;

(4)    Allocate the transaction price to the performance obligations in the contract; and

(5)    Recognize revenue when (or as) the entity satisfies a performance obligation.

At contract inception, the Company assesses the goods or services promised within each contract, whether each promised good or service is distinct, and determines those that are performance obligations. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied.

The Company enters into agreements under which it may obtain upfront payments, milestone payments, royalty payments and other fees. Promises under these arrangements may include research licenses, research services, including selection campaign research services for certain replacement targets, the obligation to share information during the research and the participation of alliance managers and in joint research committees, joint patent committees and joint steering committees. The Company assesses these promises within the context of the agreements to determine the performance obligations.

Licenses of Intellectual Property: If a license to its intellectual property is determined to be distinct from the other promises or performance obligations identified in the arrangement, the Company recognizes revenue from

Notes to Consolidated Financial Statements (Continued)

non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring proportional performance for purposes of recognizing revenue from non-refundable, upfront payments. The Company evaluates the measure of proportional performance each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone payments: The Company evaluates whether the regulatory and development milestones are considered probable of being reached and estimate the amounts to be included in the transaction price using the most likely amount method. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome to achieve the particular milestone in making this assessment. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. At the end of each reporting period, the Company re-evaluates the probability of achievement of milestones and any related constraint, and if necessary, adjust the estimate of the overall transaction price.

Sales-based milestones and royalties: For sales-based royalties, including milestone payments based on the level of sales, the Company determines whether the sole or predominant item to which the royalties relate is a license. When the license is the sole or predominant item to which the sales-based royalty relates, the Company recognize 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). To date, the Company has not recognized any sales-based royalty revenue resulting from any license agreement.

Deferred revenue, which is a contract liability, represents amounts received by the Company for which the related revenues have not been recognized because one or more of the revenue recognition criteria have not been met. The current portion of deferred revenue represents the amount expected to be recognized within one year from the consolidated balance sheet date based on the estimated performance period of the underlying performance obligation. The noncurrent portion of deferred revenue represents amounts expected to be recognized after one year through the end of the performance period of the performance obligation.

Grant Revenue

The Company concluded that the Company's government grants are not within the scope of ASC Topic 606 as they do not meet the definition of a contract with a customer. The Company has concluded that the grants meet the definition of a contribution and are non-reciprocal transactions, and has also concluded that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition, does not apply, as the Company is a business entity and the grants are with governmental agencies.

In the absence of applicable guidance under GAAP, the Company developed a policy for the recognition of grant revenue when the allowable costs are incurred and the right to payment is realized.

The Company believes this policy is consistent with the overarching premise in ASC Topic 606, to ensure that revenue recognition reflects the transfer of promised goods or services to customers in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods or services, even though there is no exchange as defined in ASC Topic 606. The Company believes the recognition of revenue as costs are incurred and amounts become realizable is analogous to the concept of transfer of control of a service over time under ASC Topic 606.

Research and Development

Research and development costs include, but are not limited to, payroll and personnel expenses, laboratory supplies, preclinical studies, compound manufacturing costs, consulting costs and allocated overhead, including rent, equipment, depreciation and utilities.

The Company has agreements with various Contract Research Organizations ("CROs") and third-party vendors. Research and development accruals of amounts due to the CRO 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 expenses on

the condensed consolidated balance sheet. Payments made to CROs under such arrangements in advance of the performance of the related services are recorded as prepaid expenses and other current assets until the services are rendered. The Company makes judgments and estimates in determining the accrued expenses balance in each reporting period. As actual costs become known, the Company adjusts its accrued expenses. For the three and nine months ended September 30, 2021 and 2020, the Company has not experienced any material differences between accrued costs and actual costs incurred.

Advertising Costs

Advertising costs are expensed as incurred. For the three and nine months ended September 30, 2021 and 2020, advertising costs were not significant.

Net Loss Per Share

Basic net loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share excludes the potential impact of convertible preferred stock, common stock options, warrants and unvested shares of restricted stock and restricted stock units because their effect would be anti-dilutive due to the Company's net loss. Since the Company had net losses for the three and nine months ended September 30, 2021 and 2020, basic and diluted net loss per common share are the same.

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. ASU No. 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this standard as of January 1, 2021, which did not have material impact on its condensed consolidated financial statements and related disclosures.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740)-Simplifying the Accounting for Income Taxes (ASU 2019-12), which is intended to simplify accounting for income taxes.

Recently Issued Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments (ASU No. 2016-13), which requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an allowance that, when deducted from the amortized cost basis of the financial assets and certain other instruments, including but not limited to available-for-sale debt securities. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down to the security. As an emerging growth company, ASU No. 2016-13 is effective for the Company for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of the adoption of ASU No. 2016-13 on its condensed consolidated financial statements.

Note 3—Revenue and Deferred Revenue

Grant Revenue

The Company’s grants and contracts reimburse it for direct and indirect costs relating to the grant projects and also provide it with a pre-negotiated profit margin on total direct and indirect costs of the grant award, excluding subcontractor costs, after giving effect to directly attributable costs and allowable overhead costs. Funds received from grants and contracts are generally deemed to be earned and recognized as revenue as allowable costs are incurred during the grant or contract period and the right to payment is realized.

Contract Revenue

The Company’s contract revenue has been generated from payments received pursuant to a license agreement (the "Vifor License") with Vifor International, Ltd. ("Vifor Pharma"), headquartered in Switzerland. The Company recognized revenue from upfront payments over the term of its estimated period of performance using a cost-based input method under Topic 606. The Company expects to continue recognizing revenue from upfront payments related to the Vifor License using the cost-based input method for the foreseeable future.

Vifor License Agreement

In November 2020, the Company entered into a license agreement with Vifor Pharma, granting Vifor Pharma global rights (excluding China, Taiwan, Hong Kong and Macau) to develop, manufacture and commercialize ANG-3777 in all therapeutic, prophylactic and diagnostic uses for renal indications, including forms of acute kidney injury (AKI), and congestive heart failure (collectively, the Renal Indications). Pursuant to the Vifor License, the Company is entitled to receive $80.0 million in upfront and near-term clinical milestone payments, including $30.0 million in up-front cash that was received in November 2020, and a $30.0 million equity investment, $5.0 million of which was a convertible note that subsequently converted into common stock with the IPO and $25.0 million of which was received in the Concurrent Private Placement with the Company’s IPO. At the time of signing, the Company is also eligible to receive post-approval milestones of up to approximately $260.0 million and sales-related milestones of up to $1.585 billion, providing a total potential deal value of up to $1.925 billion (subject to certain specified reductions and offsets), plus tiered royalties on net sales of ANG-3777 at royalty rates of up to 40%. Under the Vifor License, the Company is responsible for executing a pre-specified clinical development plan

designed to obtain regulatory approvals of ANG-3777 for delayed graft function (DGF) and AKI associated with cardiac surgery involving cardiopulmonary bypass (CSA-AKI).

On October 26, 2021, the Company announced that its Phase 3 trial of ANG-3777 in DGF did not achieve its primary endpoint and the data from the Phase 3 trial was not expected to provide sufficient evidence to support an indication in the studied DGF population. Given that a DGF indication is not supported by the Phase 3 data and thus it is unlikely that it will receive regulatory approval or achieve commercial sales, the total value of post-approval milestones under the Vifor license Agreement would be reduced to $130.0 million and the total achievable sales milestones would be $1.795 billion.

The Vifor License will continue until the expiration of the last royalty term for a licensed product in the licensed territory, unless earlier terminated. The royalty term for a licensed product is, on a country-by-country basis, shall start with the first commercial sale of such licensed product in such country and expire at the latest of (i) expiration of all licensed patents covering the composition of matter of such licensed product or method of use for such licensed product that has obtained regulatory approval in such country, (ii) expiration of all regulatory and data exclusivity applicable to such licensed product in such country, or (iii) the tenth (10th) anniversary of the date of the first commercial sale of such licensed product in such country.

Vifor Pharma may terminate the Vifor License at its sole discretion upon the earlier of (i) the acceptance for filing of an NDA covering products incorporating ANG-3777 filed with the FDA (after completion of the relevant Phase 3 clinical trial for such products), or (ii) the third anniversary of the effective date of the Vifor License. Both the Company and Vifor Pharma may terminate the Vifor License in its entirety if the other is in material breach of the Vifor License and has not cured the breach (if curable) within 60 days, or 90 days for incurable breach. In certain circumstances, in the event of the Company’s material breach of the Vifor License, Vifor Pharma may terminate the Vifor License with respect to certain major markets. In addition, both parties have the right to terminate the Vifor License upon insolvency of the other party.

The Company identified the following performance obligations in the Vifor License: (1) the global license (excluding greater China), (2) the development services, including the clinical development services including a post-approval confirmatory study, the technical development services and regulatory services and (3) the required participation on Joint Committees for coordination and oversight. The Company determined that the license is not capable of being distinct due to the specialized nature of the development services to be provided by the Company, and, accordingly, this promise was combined with the development services and participation in the joint committees as one single performance obligation.

In order to determine the transaction price, the Company evaluated all the payments to be received during the duration of the contract. Certain milestones and additional fees were considered variable consideration, which were not included in the transaction price as of September 30, 2021. The Company determined that the transaction price at the inception of the Vifor License is $15.0 million, which is 50% of the $30.0 million upfront payment due to the potential setoff defined in the contract. The Company will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur. The transaction price is recognized as license revenue using the cost-based input method over the estimated performance period, beginning on November 6, 2020, through the estimated completion of the identified performance obligation.

Using the cost-based input method, the Company recognizes revenue based on actual costs incurred as a percentage of total estimated costs as the Company completes its performance obligation. The cumulative effect of revisions to estimated costs to complete the Company’s performance obligation will be recorded in the period in which changes are identified and amounts can be reasonably estimated. These actual costs consist primarily of internal full time equivalent (FTE) efforts and third-party contract costs related to the Vifor License.

The Company reassessed the performance period as the Company does not intend to continue perform the confirmatory study for DGF given the negative clinical results in DGF. As such, the estimated date of FDA approval for the AKI indication in 2026 was determined to represent the completion of the Company’s performance obligation under the Vifor agreement. Additionally, the Company revised the total estimated costs for completion of the performance obligation to reflect the winding down of DGF-related studies. The performance period is expected to end in the fourth quarter of 2026 instead of the second quarter of 2030. The effect of this change in estimate was an increase in contract revenue by $1.0 million, a reduction in net loss by $1.0 million and an increase in basic and

diluted earnings per share by $0.03 and $0.04 for the three and nine months ended September 30, 2021, respectively.

For the three and nine months ended September 30, 2021, the Company recognized contract revenue related to the Vifor License of $1.5 million and $2.4 million, respectively. As of September 30, 2021, $27.4 million was recorded as deferred revenue, of which $3.7 million was current, on the condensed consolidated balance sheets related to the Vifor License.

The following table presents changes in Level 3 liabilities measured at fair value (in thousands):

			Warrant Liability						Convertible Notes						Series C Convertible Preferred Stock at Fair Value						Total
Balance—December 31, 2020			10,704						51,170						2,518						64,392

Balance—September 30, 2021			$	386					$	—					$	—					$	386

Both observable and unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category. Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long- dated volatilities) inputs.

The Company used an option model to measure the fair value of the Notes (on conversion date). The values of the equity underlying the conversion options in the model were estimated using equity values implied from sales of convertible preferred stock. The fair value of the Notes was impacted by the model selected as well as assumptions surrounding unobservable inputs. Key unobservable inputs include the expected volatility of the underlying equity, and the timing of an expected liquidity event.

The fair value of the warrants issued by the Company has been estimated using a variant of the Black Scholes option pricing model. The underlying equity included in the Black Scholes option pricing model was valued based on the equity value implied from sales of preferred and common stock at each measurement date. The fair value of the warrants was impacted by the model selected as well as assumptions surrounding unobservable inputs including the underlying equity value, expected volatility of the underlying equity, risk free interest rate and the expected term.

Convertible Notes

The fair value adjustment during the nine months ended September 30, 2021 is based on the final settlement amount using a conversion price of $11.57 per share on February 9, 2021. Subsequent to the closing of the IPO, there were no convertible notes outstanding.

Series C Preferred Stock

The fair value adjustment during the nine months ended September 30, 2021 is based on the final settlement amount using a conversion price of $11.57 per share on February 9, 2021. Subsequent to the closing of the IPO, there were no shares of convertible preferred stock outstanding.

Warrant Liability

The fair value adjustment for the net exercise of warrants with an exercise price of $6.43 during the nine months ended September 30, 2021 is based on the final settlement amount using the IPO price on February 9, 2021. Subsequent to the closing of the IPO, the fair value of the warrants issued by the Company has been estimated using a variant of the Black Scholes option pricing model. The underlying equity included in the Black Scholes option pricing model was valued based on the closing price of common stock at each measurement date.

During the three months ended September 30, 2021 and 2020, the fair value of the warrants decreased by $0.1 million and increased by $0.5 million, respectively. The change in fair value of warrant liability in both periods are recognized in the condensed consolidated statements of operations. During the nine months ended September

30, 2021 and 2020, the increase in the fair value of the warrants of $3.2 million and $1.3 million, respectively, are recognized in change in fair value of warrant liability in the condensed consolidated statements of operations.

A summary of the weighted average (in aggregate) significant unobservable inputs (Level 3 inputs) used in measuring the Company's warrant liabilities that are categorized within Level 3 of the fair value hierarchy as of September 30, 2021 and December 31, 2020 was as follows:
