Organization and Nature of Business

Note 1 – Organization and Nature of Business

Immuneering Corporation, a Delaware corporation, (“Immuneering” or the “Company”) was incorporated in 2008. The Company is a biopharmaceutical company with an emerging pipeline focused on improving patient outcomes across a spectrum of debilitating oncologic and neurologic diseases by applying the Company’s deep knowledge of translational bioinformatics to every stage of the drug development process. The Company has more than a decade of experience in translational bioinformatics and generating insights into drug mechanisms of action and patient treatment responses. Building on this experience, the Company developed a disease agnostic platform that enables the Company to utilize human data, novel biology and chemistry, and translational planning to create and advance the Company’s wholly owned pipeline.

On October 30, 2019, Immuneering formed a wholly owned subsidiary, Immuneering Securities Corporation (“ISC”), a Massachusetts securities corporation, for the sole purpose of buying, selling and holding securities on the Company’s behalf. Immuneering and ISC are collectively referred to as “the Company” throughout these condensed consolidated financial statements.

Since inception, the Company has devoted substantially all of its efforts to business planning, service revenue generation, research and development, recruiting management and technical staff, and raising capital. The Company has financed its operations through service revenues, the issuance of convertible debt and the sale of convertible preferred stock and common stock.

The Company is subject to a number of inherent risks associated with any biotechnology company that has substantial expenditures for research and development. These risks include, but are not limited to, the need to obtain adequate additional funding, possible failure of clinical trials or other events demonstrating lack of clinical safety or efficacy of its product candidates, dependence on key personnel, reliance on third-party service providers for manufacturing drug product and conducting clinical trials, the ability to successfully secure its proprietary technology, and risks related to the regulatory approval and commercialization of a product candidate. There can be no assurance that the Company’s research and development program will be successful. In addition, the Company operates in an environment of rapid technological change and is largely dependent on the services of its employees, advisors, and consultants.

On August 3, 2021, the Company completed its initial public offering (“IPO”) pursuant to which it issued and sold 8,625,000 shares of its Class A common stock, inclusive of 1,125,000 shares of its Class A common stock sold pursuant to the full exercise of the underwriters’ option to purchase additional shares. The aggregate net proceeds received by the Company from the IPO were $120,318,750, after deducting underwriting discounts and commissions, but before deducting offering costs payable by the Company, which were $2,124,317. Upon the closing of the IPO, all 8,528,078 shares of the Company’s convertible preferred stock then outstanding automatically converted into 11,939,281 shares of Class A common stock. Upon the conversion of the convertible preferred stock, the Company reclassified the carrying value of the convertible preferred stock to common stock (at par value) and additional paid-in capital (see Note 8).

To date, the Company has funded its operations through service revenues, and with proceeds from the sale of its capital stock and convertible notes and, most recently, with proceeds from the IPO. The Company has incurred recurring losses over the past several years and as of September 30, 2021, the Company had an accumulated deficit of $48,489,029. The Company expects to continue to generate operating losses for the foreseeable future. The future viability of the Company is dependent on its ability to raise additional capital to finance its operations. The Company’s inability to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. There can be no assurances that additional funding will be available on terms acceptable to the Company, or at all. If the Company is unable to raise additional funds when needed, it may be required to delay, reduce the scope of, or eliminate development programs, which may adversely affect its business and operations. Management considers that there are no conditions or events, in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern and estimates that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months from the issuance date of the interim condensed consolidated financial statements. The full extent to

which coronavirus (“COVID-19”) pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including expenses and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and its variants and the actions taken to contain or treat COVID-19 and its variants, as well as the economic impact on local, regional, national and international markets. The Company has considered potential impacts arising from the pandemic related to COVID-19 and its variants and is not presently aware of any events or circumstances that would require the Company to update its estimates, judgements or revise the carrying values of its assets or liabilities.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with accounting standards set by the Financial Accounting Standards Board (“FASB”). The FASB sets generally accepted accounting principles (“GAAP”) to ensure the condensed consolidated financial statements are consistently reported. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codifications (“ASC”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation.

There have been no material changes to the accounting policies of the Company as those set forth in Note 2 to the audited consolidated financial statements contained in the final prospectus, dated July 29, 2021, filed with the SEC on July 30, 2021 pursuant to Rule 424(b) relating to our Registration Statement on Form S-1 (File No. 333-257791) (the “Prospectus”).

Unaudited Interim Financial Information

The unaudited interim condensed consolidated financial statements of the Company have been prepared, without audit, in accordance with GAAP and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been omitted from the unaudited interim condensed consolidated financial statements, as is permitted by such rules and regulations. While we believe that the disclosures presented are adequate in order to make the information not misleading, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes for the year ended December 31, 2020.

It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, operating results and cash flows. Revenues and net loss for any interim period are not necessarily indicative of future or annual results.

Stock Split

On July 23, 2021, the Company approved a one-for-1.4 stock split which was consummated in connection with the Company’s IPO. All information in the accompanying financial statements and notes thereto regarding share amounts of common stock, price per share of common stock and the conversion factor for Series A and Series B Preferred Stock into common stock have been adjusted to reflect the application of the stock split on a retroactive basis.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses during the reporting periods. These estimates and assumptions are based on current facts, historical experience and various other factors believe to be reasonable under the circumstances, the results of which form the basis for making judgements about the carrying values of assets liabilities and the recording of expenses that are not readily apparent from other sources. Significant estimates reflected in these condensed consolidated financial statements included but are not limited to, the research and

development expenses, determination of fair value of stock-based awards, the valuation of common stock, and the right-to-use assets and operating lease liability. Actual results may differ materially and adversely from these estimates.

Recently Issued Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as amended (“Jobs Act”). The Jobs Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to avail itself of this extended transition period and, as a result, we will not be required to adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

In 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements. The new standard, as amended, requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The targeted transition relief standard allows filers an option to irrevocably elect the fair value option of ASC 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) will become effective for the Company on January 1, 2023. The Company is currently assessing the impact of the adoption of this guidance on its condensed consolidated financial statements.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance for income taxes and making other minor improvements. The amendments are effective for annual reporting periods beginning after December 15, 2020 with early adoption permitted. The Company is currently assessing the impact of the adoption of this guidance on its condensed consolidated financial statements.

Fair Value Measurements

Note 4 – Fair Value Measurements

We record cash equivalents and marketable securities at fair value. ASC 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and our own assumptions (unobservable inputs). The hierarchy consists of three levels:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, directly or indirectly, for substantially the full term of the asset or liability.

Level 3 – Unobservable inputs that reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

The following table summarizes our cash equivalents and marketable securities measured at fair value on a recurring basis as of September 30, 2021:


		Level 1		Level 2		Level 3		Total
Assets:
Cash equivalents
Money market	$	29,343,849	$	-	$	-	$	29,343,849
Commercial paper		-		13,497,775		-		13,497,775
Total cash equivalents		29,343,849		13,497,775		-		42,841,624

Total cash equivalents and marketable securities	$	49,762,139	$	45,728,521	$	-	$	95,490,660

Cash equivalents and marketable securities have been initially valued at the transaction price and subsequently, at the end of each reporting period, valued utilizing third-party pricing services or other observable market data. The pricing services utilize industry standard valuation models, including both income and market-based approaches, and observable market inputs to determine value. After completing our validation procedures, we did not adjust or override any fair value measurements provided by the pricing services as of September 30, 2021.

There have been no changes to the valuation methods during the nine months ended September 30, 2021. We have no financial assets or liabilities that were classified as Level 3 at any point during the nine months ended September 30, 2021. There were no marketable securities as of December 31, 2020.

Note 7 – Convertible Preferred Stock

Series A Preferred Stock

In September 2019, the Company authorized the sale and issuance of up to 1,987,979 shares of Series A Preferred Stock, $0.001 par value per share, at an original issuance price of $8.5514 per share. In January 2020, the number of shares authorized for the Series A Preferred Stock was increased to 2,495,933 shares. The Series A Preferred Stock financing was structured to be issued in rolling closes during 2019 and 2020.

On September 20, 2019, the Company issued an additional 1,122,458 shares of Series A Preferred Stock for gross cash proceeds of $9,598,847 and issued 785,706 shares of Series A Preferred Stock in conjunction with the conversion of the outstanding amount of the Convertible Notes. In 2019, the Company incurred issuance costs of $200,587 in connection with this offering.

The Company received funds for issuance of an additional 468,315 shares of Series A Preferred Stock for gross cash proceeds of $4,004,975 through December 31, 2019. Of these shares, 410,436 shares of Series A Preferred Stock for gross cash proceeds of $3,509,802 exceeded the authorized amount allowed by the articles of incorporation, resulting in a liability of $3,509,802 and a total of 1,966,043 shares of Series A Preferred Stock outstanding at December 31, 2019. In January 2020, the shares that were previously classified as a liability as of December 31, 2019 were reclassified to temporary equity upon the approved increase to authorized shares of Series A Preferred Stock.

In January 2020, the Company issued 119,454 additional shares of Series A Preferred Stock for gross cash proceeds of $1,021,413. The Company incurred issuance costs of $23,610 in connection with the financing in January 2020.

Series B Preferred Stock

In December 2020, the Company authorized the sale and issuance of up to 6,032,183 shares of Series B Preferred Stock, $0.001 par value per share, at an original issuance price of $10.2782 per share. The Series B Preferred Stock financing was structured to close in two tranches. The first tranche closed in December 2020 and the Company issued 3,619,292 shares of Series B Preferred Stock for gross cash proceeds of $37,199,929. The Company incurred issuance costs of $216,019 in connection with the financing in December 2020.

The Company determined the right of the investors to purchase 2,412,853 shares of Series B Preferred Stock in the second tranche does not meet the definition of a freestanding financial instrument as it is not separable from the Series B Preferred Stock issued in the first tranche. The issuance of the second tranche is subject to the Company meeting certain development milestones or at the election of the holders of at least a majority of the then outstanding shares of Series B Preferred Stock which must include one specific shareholder (the “Requisite Holders”). Each holder of Series B Preferred Stock may elect to purchase their requisite shares of the second tranche at any time. As of March 31, 2021, the Company had not met these development milestones nor did the Requisite Holders elect to purchase the second tranche prior to meeting these milestones and therefore no shares of the second tranche were issued.

In April and May 2021, all 2,412,853 shares of the second tranche of Series B Preferred Stock were issued based on the voluntary election of substantially all of the holders of Series B Preferred Stock. The Company received gross proceeds of $24,799,786. The Company incurred issuance costs of $10,935 in connection with the second tranche of Series B Preferred Stock.

The rights and preferences of the Series A Preferred Stock and Series B Preferred Stock (“Preferred Stock”) are as described below:

Conversion

Each share of Preferred Stock may be converted at any time, at the option of the holder, into shares of Class A common stock, subject to the applicable conversion rate as determined by dividing the original issue price by the conversion price. The conversion price for the Series A Preferred Stock and Series B Preferred Stock (as may be adjusted for certain customary dilutive events) is $6.1081 and $7.3416, respectively. The Preferred Stock automatically convert into shares of Class A common stock at the then effective conversion rate upon the closing of a public offering of the Company’s securities with gross proceeds to the Company of at least $75,000,000 and a share price of at least $7.3416 or at the election of the holders of the Requisite Holders.

Holders of Series B Preferred Stock that would beneficially own at least 9.9% of any then outstanding class of equity securities may elect to receive a portion of their converted Series B Preferred Stock as Class B common stock upon conversion.

Upon the closing of the IPO on August 3, 2021, all 8,528,078 shares of the Company’s convertible preferred stock then outstanding automatically converted into 11,939,281 shares of Class A common stock.

Dividends

Preferred Stockholders are entitled to receive per annum dividends of 7% of the original issue price share, payable only when, as and if declared by the Board of Directors. The right to receive these dividends is not cumulative, and therefore, if not declared in any year, the right to receive such dividends shall terminate and not carry forward into the next year. As of September 30, 2021 and December 31, 2020, no dividends had been declared.

Voting Rights

Preferred Stock and common stock vote together as one class on an as converted basis. Common stock voting rights on certain matters are subject to the powers, preferences, and rights of the Preferred Stock. Preferred Stockholders are entitled to vote on all matters and shall have the number of votes equal to the number of shares of common stock into which the shares of Preferred Stock held by such holder are then convertible. As long as 2,132,029 shares of Preferred Stock are outstanding, certain actions such as mergers, acquisition, liquidation, dissolution, wind up of business, and deemed liquidation events, must be approved by the holders of at least a majority of the then-outstanding shares of Preferred Stock.

Liquidation Preference

Upon liquidation, dissolution, or winding up of business, holders of Preferred Stock are entitled to receive a liquidation preference in priority to holders of common stock at the original respective Preferred Stock issue price for such series. If assets available for distribution are insufficient to satisfy the liquidation payment to holders of Preferred Stock in full, assets available for distribution will be allocated among holders of Preferred Stock on a pari passu basis at an amount per share equal to the greater of the respective original Preferred Stock issue price for such series plus any declared but unpaid dividends or such amount had all shares been converted to common stock.

When holders of Preferred Stock are satisfied in full, any excess assets available for distribution will be allocated ratably among common stock holders based on their pro rata shareholdings. Upon a deemed liquidation event, as defined in the articles of incorporation, holders have the option to redeem their shares at the liquidation payment amounts summarized above.

Redemption

Other than described above, the shares of Preferred Stock are not redeemable.

These warrants vested immediately upon issuance, became exercisable on January 9, 2021 and have a 10-year term set to expire on January 9, 2030. The Company evaluated the terms of these warrants and determined that equity classification was appropriate. As of December 31, 2020, no warrants had been exercised. During June 2021, all warrant holders exercised their warrants to purchase an aggregate of 308,308 shares of common stock. As of September 30, 2021, there were no warrants outstanding.

The aggregate net proceeds received by the Company from the IPO were $120,318,750, after deducting underwriting discounts and commissions, but before deducting offering costs payable by the Company, which were $2,124,317. Upon the closing of the IPO, all 8,528,078 shares of the Company’s convertible preferred stock then outstanding automatically converted into 11,939,281 shares of Class A common stock. Upon the conversion of the convertible preferred stock, the Company reclassified the carrying value of the convertible preferred stock to common stock (at par value) and additional paid-in capital.

On August 3, 2021 in connection with the closing of the IPO, the Company filed a restated certificate of incorporation, which amended and restated the Company’s certificate of incorporation to, among other things: (i) increase the number of authorized shares of common stock to 200,000,000 shares of Class A common stock, 20,000,000 shares of Class B common stock, par value $0.001 per share, and (ii) authorize 10,000,000 shares of Preferred Stock; and (iii) authorize the Board to establish the rights, preferences and restrictions on any unissued series of Preferred Stock.

Net Loss Per Share Attributable to Common Stockholders

Net Loss Per Share Attributable to Common Stockholders

Note 9 - Net Loss Per Share Attributable to Common Stockholders

Net loss per share of common stock is computed using the two-class method required for multiple classes of common stock and participating securities based upon their respective rights to receive dividends as if all income for the period has been distributed. The rights, including the liquidation and dividend rights and sharing of losses, of the Class A and Class B common stock are identical, other than voting rights. As the liquidation and dividend rights and sharing of losses are identical, the undistributed earnings are allocated on a proportionate basis and the resulting net loss per share attributed to common stockholders is therefore the same for Class A and Class B common stock on an individual or combined basis.

The Company’s participating securities include the Company’s Preferred Stock, as the holders are entitled to receive noncumulative dividends in the event that a dividend is paid on common stock. The holders of Preferred Stock do not have a contractual obligation to share in losses of the Company, and therefore during periods of loss there is no allocation required under the two-class method.

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 during the period, adjusted for outstanding shares that are subject to repurchase.

Diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period using the treasury stock method or the if-converted method based on the nature of such securities. The Company has reported net losses for all periods presented, therefore diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Basic and diluted net loss per share attributable to common stockholders was calculated at September 30, 2021 and 2020 as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020

Numerator:
Net loss	$	(8,534,073)	$	(4,399,079)	$	(22,751,389)	$	(11,203,961)
Denominator - basic and diluted:
Weighted-average common shares outstanding, basic and diluted		18,286,352		4,950,129		9,445,862		4,950,129
Net loss per share - basic and diluted	$	(0.47)	$	(0.89)	$	(2.41)	$	(2.26)

The following table sets forth the potentially dilutive securities that have been excluded from the calculation of diluted net loss per share because to include them would be anti-dilutive (in common stock equivalent shares) at September 30, 2021 and 2020:

Stock-Based Compensation

Stock-Based Compensation

Note 10 – Stock-Based Compensation

During 2015, the Company established the Long Term Incentive Plan (“Incentive Plan”), under which incentive stock options, nonqualified stock options, restricted stock or other awards may be awarded to employees, directors or consultants of the Company. The options typically vest over a four-year period. As of September 30, 2021, the maximum number of shares available for issuance under the Incentive Plan was 2,825,173 shares. As of September 30, 2021, the number of shares available for future grants under the Incentive Plan was 137,950 shares. However, from and after the effectiveness of the Company’s 2021 Incentive Award Plan, no additional awards will be granted under the Incentive Plan.

On July 23, 2021, the Company’s board of directors adopted, and on July 23, 2021 its stockholders approved, the 2021 Incentive Award Plan (the “2021 Plan”), which became effective on July 29, 2021. The 2021 Plan provides for the grant of incentive stock options, stock appreciation rights, restricted stock awards, restricted stock units, and other stock-based awards. The number of shares reserved for issuance under the 2021 Plan is initially equal to 2,590,000 plus an annual increase on the first day of each calendar year, beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (i) 4% of the aggregate number of shares of Class A common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of Class A common stock as determined by the Board of Directors. No more than 15,350,000 shares of Class A

common stock may be issued under the 2021 Plan upon the exercise of incentive stock options. Shares issued under the 2021 Plan may be authorized but unissued shares, shares purchased on the open market or treasury shares. If an award under the 2021 Plan expires, lapses or is terminated, exchanged for or settled in cash, surrendered, repurchased, cancelled without having been fully exercised/settled or forfeited, any unused shares subject to the award will, as applicable, become or again be available for new grants under the 2021 Plan. In addition, shares subject to stock options issued under the Incentive Plan may become available for issuance under the 2021 Plan to the extent such stock options are canceled, forfeited, exchanged, settled in cash or otherwise terminated. As of September 30, 2021, there were 2,397,232 shares available for future issuance under the 2021 Plan.

On July 23, 2021, the Company’s board of directors adopted, and on July 23, 2021 its stockholders approved, the 2021 Employee Stock Purchase Plan (the “2021 ESPP”), which became effective on July 29, 2021. A total of 250,000 shares of Class A common stock were initially reserved for issuance under this plan. The number of shares of Class A common stock that may be issued under the 2021 ESPP will automatically increase on the first day of each calendar year, beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (i) 1% of the shares of Class A common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of Class A common stock as determined by the board of directors, provided that not more than 3,340,000 shares of Class A common stock may be issued under the 2021 ESPP. As of September 30, 2021, no shares had been issued under the 2021 ESPP.

During the three and nine months ended September 30, 2021, the Company recognized stock-based compensation expense of $636,806 and $1,170,040, respectively. During the three and nine months ended September 30, 2020, the Company recognized stock-based compensation expense of $310,465 and $870,162, respectively. As of September 30, 2021, compensation expense remaining to be recognized for outstanding stock options was $7,990,487 and to be recognized over a weighted-average period of 3.07 years.

The fair value of options granted is calculated on the grant date using the Black-Scholes option valuation model. The Company historically has been a private company and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer public companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. For the nine months ended September 30, 2021, the Company granted 1,353,662 shares of stock options at a weighted-average grant date fair value of $9.56. For the nine months ended September 30, 2020, the Company granted 336,626 shares at a weighted-average grant date fair value of $3.02.

The Company used the following assumptions in its application of the Black-Scholes option pricing model for grants during the nine months ended September 30, 2021 and 2020:


	Nine Months Ended September 30,
	2021	2020

Weighted-average risk-free interest rate	0.885%-1.71%	0.36% - 1.21%
Expected term (in years)	5.83 - 10 years	5.92 - 10 years
Expected dividend yield	0%	0%
Expected volatility	68.92% - 80.99%	67.30% - 77.08%

The following table summarizes the stock option activity during the nine months ended September 30, 2021 under the Plan:

Operating Leases

The Company leases office space in Cambridge, Massachusetts, New York, New York and as of July 2021, San Francisco, California, pursuant to short-term arrangements. The Cambridge and San Francisco leases are on a month-to-month basis, requiring one month’s notice before termination. The New York lease is renewable on a quarterly basis and the last renewal was on August 3, 2021 which extended the lease term until December 31, 2021. These lease agreements include payments for lease and non-lease components and the Company has elected to not separate such components and these payments were recognized as rent expense.

As of September 30, 2021, total future minimum lease payments for its short-term leases in Cambridge, Massachusetts, New York, New York and San Francisco, California was $23,620 due in 2021 and $11,040 due in 2022. The Company leases storage space for its electronic data equipment in Somerville, Massachusetts. This lease is renewable on an annual basis effective every March 1st. Prior to September 30, 2021, the Company renewed the lease through March 31, 2022. As of September 30, 2021, total future minimum lease payments for this lease were $5,354 due in 2021 and $3,569 due in 2022.

In July 2019, the Company entered into an office lease in San Diego, California (“2019 San Diego Lease”) with a lease term of 24 months with no escalations and variable costs based on additional number of employees using the facility. This lease was cancelable upon a 30-day notice period. Upon adoption of ASC 842 on January 1, 2020, a right-to-use asset and lease liability based on the fixed costs was recognized by the Company for $61,822. Effective September 20, 2020, the lease was terminated, and the remaining right-of-use asset and lease liability were derecognized. No gain or loss was recognized for the termination of this lease.

In October 2020, the Company entered into an office lease in San Diego, California (“2020 San Diego Lease”) with a lease term of 67 months. At the lease commencement date, a right-to-use asset and lease liability was recognized by the Company for $637,863.

Maturities of the lease liabilities due under the Company’s 2020 San Diego Lease as of September 30, 2021 are as follows:


	Amount
Remainder of 2021	$	28,367
2022		115,430

Weighted-average remaining lease term - operating leases		4.58 years		5.58 years
Weighted-average discount rate - operating leases		6.0%		6.0%

As the Company’s leases typically do not provide an implicit rate, the Company uses an estimate of its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments.

Litigation

From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of its business activities and may be exposed to litigation in connection with its products and operations. The Company’s policy is to assess the likelihood of any adverse judgments or outcomes related to legal matters, as well as ranges of probable losses. When it is probable that future expenditures will be made and can be reasonably estimated the Company will accrue a liability for such matters. Significant judgement is required to determine both probability and estimated amount. The Company is not aware of any material legal matters.

Clinical Research Contracts

The Company may enter into contracts in the normal course of business with clinical research organizations for clinical trials, with contract manufacturing organizations for clinical supplies, and with other vendors for preclinical studies, supplies and other services for our operating purposes. These contracts generally provide for termination with a 30-day notice.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2021
Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements have been prepared in accordance with accounting standards set by the Financial Accounting Standards Board (“FASB”). The FASB sets generally accepted accounting principles (“GAAP”) to ensure the condensed consolidated financial statements are consistently reported. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codifications (“ASC”). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. There have been no material changes to the accounting policies of the Company as those set forth in Note 2 to the audited consolidated financial statements contained in the final prospectus, dated July 29, 2021, filed with the SEC on July 30, 2021 pursuant to Rule 424(b) relating to our Registration Statement on Form S-1 (File No. 333-257791) (the “Prospectus”).
Unaudited Interim Financial Information	Unaudited Interim Financial Information The unaudited interim condensed consolidated financial statements of the Company have been prepared, without audit, in accordance with GAAP and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been omitted from the unaudited interim condensed consolidated financial statements, as is permitted by such rules and regulations. While we believe that the disclosures presented are adequate in order to make the information not misleading, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes for the year ended December 31, 2020. It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, operating results and cash flows. Revenues and net loss for any interim period are not necessarily indicative of future or annual results.
Stock Split	Stock Split On July 23, 2021, the Company approved a one-for-1.4 stock split which was consummated in connection with the Company’s IPO. All information in the accompanying financial statements and notes thereto regarding share amounts of common stock, price per share of common stock and the conversion factor for Series A and Series B Preferred Stock into common stock have been adjusted to reflect the application of the stock split on a retroactive basis.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses during the reporting periods. These estimates and assumptions are based on current facts, historical experience and various other factors believe to be reasonable under the circumstances, the results of which form the basis for making judgements about the carrying values of assets liabilities and the recording of expenses that are not readily apparent from other sources. Significant estimates reflected in these condensed consolidated financial statements included but are not limited to, the research and development expenses, determination of fair value of stock-based awards, the valuation of common stock, and the right-to-use assets and operating lease liability. Actual results may differ materially and adversely from these estimates.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as amended (“Jobs Act”). The Jobs Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to avail itself of this extended transition period and, as a result, we will not be required to adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. In 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements. The new standard, as amended, requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. It also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The targeted transition relief standard allows filers an option to irrevocably elect the fair value option of ASC 825-10, Financial Instruments-Overall, applied on an instrument-by-instrument basis for eligible instruments. ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) will become effective for the Company on January 1, 2023. The Company is currently assessing the impact of the adoption of this guidance on its condensed consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance for income taxes and making other minor improvements. The amendments are effective for annual reporting periods beginning after December 15, 2020 with early adoption permitted. The Company is currently assessing the impact of the adoption of this guidance on its condensed consolidated financial statements.
