Cognition Therapeutics, Inc. and Subsidiary

Notes to Consolidated Financial Statements

(unaudited)

(in thousands, except share and per share amounts)

1. Description of Business and Financial Condition

Cognition Therapeutics, Inc. (the “Company”) was incorporated as a Delaware corporation on August 21, 2007. The Company is a biopharmaceutical company developing disease modifying therapies targeting age-related degenerative diseases and disorders of the central nervous system (“CNS”) and retina. The Company’s pipeline candidates were discovered using proprietary biology and chemistry platforms designed to identify novel drug targets and disease-modifying therapies that address dysregulated pathways specifically associated with neurodegenerative diseases. The Company was founded on the unique combination of biological expertise around these targets, including proprietary assays that emphasize functional responses, and proprietary medicinal chemistry intended to produce novel, high-quality small-molecule drug candidates.

In January 2024, the Company ceased operations at Cognition Therapeutics PTY LTD, a wholly owned subsidiary (the “Subsidiary”) and completed its liquidation of the Subsidiary (the “Liquidation”). In accordance with the Liquidation, the Company removed the AOCI balance associated with the currency translation adjustments and recorded a loss on liquidation of the Subsidiary in accumulated deficit.

On December 23, 2022, the Company filed a Registration Statement on Form S-3 (File No. 333-268992) (the “Shelf”) with the Securities and Exchange Commission (“SEC”) in relation to the registration of common stock, preferred stock, debt securities, warrants, subscription rights, and/or units of any combination thereof of up to $200,000 in aggregate. The Shelf was declared effective on January 3, 2023 by the SEC. The Company also simultaneously entered into a sales agreement with Cantor Fitzgerald & Co. and B. Riley Securities, Inc. (the “Sales Agents”) providing for the offering, issuance and sale by the Company of up to $40,000 of its common stock from time to time in “at-the-market” offerings under the Shelf (the “ATM”). During the six months ended June 30, 2024, the Company sold 191,273 shares of its common stock pursuant to the ATM for gross proceeds of approximately $393. Please refer to Note 7 for further details.

On March 10, 2023, the Company entered into a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) for an equity line financing (the “Purchase Agreement”). The Purchase Agreement provides that, subject to the terms and conditions set forth therein, the Company has the right, but not the obligation, to direct Lincoln Park to purchase up to $35,000 of shares of common stock in the Company’s sole discretion, over a 36-month period commencing on March 10, 2023. The Company filed a prospectus supplement to its Registration Statement on Form S-3 (File No. 333-268992) covering the resale of shares of common stock that may be issued under the Purchase Agreement. As part of the Purchase Agreement, the Company issued 189,856 shares of its common stock as consideration for Lincoln Park’s commitment to purchase shares of common stock under the Purchase Agreement. During the six months ended June 30, 2024, the Company did not sell any shares of common stock to Lincoln Park. As of June 30, 2024, $34,795 was available to draw pursuant to the Purchase Agreement. Please refer to Note 7 for further details.

On March 14, 2024, the Company closed a follow-on public offering of 6,571,428 shares of the Company’s common stock at a public offering price of $1.75 per share (“March 2024 Offering”). As part of the March 2024 Offering, the underwriters exercised their option to purchase 985,714 shares of the Company’s common stock on March 28, 2024, at a public offering price of $1.75 per share. The gross proceeds from the March 2024 Offering were $13,225 and the net proceeds were approximately $11,896, after deducting underwriting discounts and commissions and other offering related expenses payable by the Company.

Table of Contents

Liquidity and Going Concern

The Company’s Consolidated Financial Statements have been prepared on a going concern basis, which contemplates the continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. The Company has incurred recurring losses since inception, including net losses of $16,192 for the six months ended June 30, 2024 and $25,788 for the year ended December 31, 2023. As of June 30, 2024, the Company had cash and cash equivalents of $28,533 compared to $29,922 of cash and cash equivalents as of December 31, 2023. The Company has incurred losses and negative cash flows from operations and had an accumulated deficit of $157,381 as of June 30, 2024. The Company expects to continue to incur losses for the foreseeable future.

As of August 8, 2024, the date of issuance of these Consolidated Financial Statements, the Company believes that its cash and cash equivalents as of June 30, 2024 is not sufficient to fund operations for the period through one year after the date of this filing and therefore substantial doubt exists about the Company’s ability to continue as a going concern.

To execute its business plans, the Company will need substantial funding to support its continuing operations and pursue its growth strategy. Until such time that the Company can generate significant revenue from product sales, if ever, the Company expects to finance its operations through the sale of common stock in public offerings and/or private placements, debt financings or other capital sources, including collaborations with other companies or other strategic transactions. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or abandon its product development programs, which could have a material adverse effect on its business prospects.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements as of June 30, 2024, and for the three and six months ended June 30, 2024 and 2023, have been prepared in accordance with the rules and regulations of the SEC and generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of the Company’s management, the accompanying unaudited interim consolidated financial statements contain all adjustments that are necessary to present fairly the Company’s financial position as of June 30, 2024, the statements of operations and comprehensive loss and stockholders’ equity for the three and six months ended June 30, 2024 and 2023, and cash flows for the six months ended June 30, 2024 and 2023. Such adjustments are of a normal and recurring nature. The results for the three and six months ended June 30, 2024 are not necessarily indicative of the results for the year ending December 31, 2024, or for any future period. These interim financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2023, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 26, 2024.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of interest-bearing deposits at various financial institutions and money markets. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Table of Contents

Receivables

Grant Receivables

Grant receivables relate to outstanding amounts due for reimbursable expenditures of awarded grants issued by the National Institute of Health (“NIH”) and are carried at their estimated collectible amounts. The Company expects all receivables to be collectible, and accordingly, there is no allowance for doubtful accounts required on these grant receivables.

Grant Income

The Company generates grant income through grants from government and other (non-government) organizations. Grant income is recognized in other income (expense) in the period in which the reimbursable research and development services are incurred and the right to payment is realized. Deferred grant income represents grant proceeds received by the Company prior to the period in which the reimbursable research and development services are incurred. For the three and six months ended June 30, 2024, the Company generated grant income of $7,311 and $12,223, respectively, as compared to $6,925 and $10,351 for the three and six months ended June 30, 2023, respectively, primarily from reimbursements from the National Institute of Aging (the “NIA”), a division of the NIH for aging research. The current and non-current portion of deferred grant income as of June 30, 2024 was $1,453 and $0, respectively, as compared to the current and non-current portion of deferred grant income as of December 31, 2023 of $1,701 and $0, respectively.

The grants awarded relate to agreed-upon direct and indirect costs for specific studies or clinical trials, which may include personnel and consulting costs, costs paid to contract research organizations (“CROs”), research institutions and/or consortiums involved in the grants, as well as facilities and administrative costs. These grants are cost plus fixed fee arrangements in which the Company is reimbursed for its eligible direct and indirect costs over time, up to the maximum amount of each specific grant award. Only costs that are allowable under the grant award, certain government regulations and the NIH’s supplemental policy and procedure manual may be claimed for reimbursement, and the reimbursements are subject to routine audits from governmental agencies from time to time. While these NIH grants do not contain payback provisions, the NIH or other government agency may review the Company’s performance, cost structures and compliance with applicable laws, regulations, policies and standards and the terms and conditions of the applicable NIH grant. If any of the expenditures are found to be unallowable or allocated improperly or if the Company has otherwise violated terms of such NIH grant, the expenditures may not be reimbursed and/or the Company may be required to repay funds already disbursed. To date, the Company has not been found to have breached the terms of any NIH grant. As of June 30, 2024, the Company has been awarded grants with project periods that extend through May 31, 2027, subject to extension.

Research and Development Costs

The Company is involved in research and development of treatments for a variety of diseases related to the central nervous system, with a focus on Alzheimer’s disease, dementia with Lewy bodies, and geographic atrophy (“GA”) secondary to dry age-related macular degeneration. Research and development costs are expensed as incurred. Research and development expenses consist principally of personnel costs, including salaries, stock-based compensation, and benefits for employees, third-party license fees and other operational costs related to its research and development activities, including allocated facility-related expenses and external costs of outside vendors, including CROs, and other direct and indirect costs. Non-refundable research and development costs are deferred and expensed as the related goods are delivered or services are performed. Costs for external development activities are recognized based on an evaluation of the progress to completion of specific tasks. Costs for certain research and development activities are recognized based on the pattern of performance of the individual arrangements, which may differ from the pattern of billings incurred, and are reflected in the consolidated financial statements as prepaid expenses or as accrued research and development expenses.

Equity-based Compensation

Following the provisions of ASC 718, Compensation — Stock Compensation, the Company recognizes compensation expense for equity-based grants using the straight-line attribution method, in which the expense is recognized ratably over the requisite service period within operating expenses based on the grant date fair value. The Company also has granted awards subject to performance-based vesting. The Company recognizes compensation expense for these awards commencing in the period in which the vesting condition becomes probable of achievement. The grant date fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model. Forfeitures are recognized in the period in which they occur.

Black-Scholes requires inputs based on certain subjective assumptions, including (i) the expected stock price volatility, (ii) the expected term of the award, (iii) the risk-free interest rate and (iv) expected dividends. Due to a lack of sufficient public market data for the Company’s common stock and lack of company-specific historical and implied volatility data, the Company has based its computation of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to the Company, including stage of product development and life science industry focus. The historical volatility is calculated based on a period of time commensurate with expected term assumption. The Company uses the simplified method to calculate the expected term for stock options granted to employees whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the stock options due to its lack of sufficient historical data. The risk-free interest rate is based on U.S. Treasury securities with a maturity date commensurate with the expected term of the associated award. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock.

Prior to the IPO, due to the absence of an active market for the Company’s common stock, the Company utilized methodologies in accordance with the framework of the American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation, to estimate the fair value of its common stock. In determining the exercise prices for stock options granted, the Company has considered the estimated fair value of the common stock as of the measurement date. The estimated fair value of the common stock has been determined at each grant date based upon a variety of factors, including the illiquid nature of the common stock, arm’s-length sales of the Company’s capital stock (including convertible preferred stock), the effect of the rights and preferences of the preferred stockholders and the prospects of a liquidity event. Among other factors are the Company’s financial position and historical financial performance, the status of technological developments within the Company’s research, the composition and ability of the current research and management team, an evaluation or benchmark of the Company’s competition and the current business climate in the marketplace. Significant changes to the key assumptions underlying the factors used could result in different fair values of common stock at each valuation date. Subsequent to the IPO, the board of directors determines the fair value of the shares of common stock underlying the stock-based awards based off of the closing price as reported on the Nasdaq Stock Market LLC on the grant date.

Concentration of Credit Risk

The Company’s financial instruments that are exposed to credit risks consist of cash and cash equivalents. The Company maintains its cash and cash equivalents in bank deposit accounts which, at times, may exceed the federally insured limit. The Company has not experienced any losses in these accounts and does not believe it is exposed to any significant credit risk related to these funds.

Table of Contents

Fair Value of Financial Instruments

The Company applies ASC 820, Fair Value Measurement (“ASC 820”), which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.

The carrying value of the Company’s cash and cash equivalents, grants receivable, prepaid expense, other receivables, other assets, accounts payable, accrued expenses and other liabilities approximate fair value because of the short-term maturity of these financial instruments.

The valuation hierarchy is composed of three levels. The classification within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The levels within the valuation hierarchy are described below:

●

Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.

●

Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.

●

Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss per share by the weighted-average number of shares of common stock outstanding during each period. Diluted net loss per share includes the effect, if any, from the potential exercise or conversion of securities, such as convertible preferred stock and stock options, which would result in the issuance of incremental shares of common stock. For diluted net loss per share, the weighted-average number of shares of common stock is the same for basic net loss per share due to the fact that when a net loss exists, dilutive securities are not included in the calculation as the impact is anti-dilutive.

Segments

The Company has determined that it operates and manages one operating segment, which is the business of developing and commercializing therapeutics. The Company’s chief operating decision maker, its chief executive officer, reviews financial information on an aggregate basis for the purpose of allocating resources.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (a) no longer an emerging growth company or (b) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Recent Accounting Pronouncements

Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements (“ASU 2023-06”), to clarify or improve disclosure and presentation requirements of a variety of topics and align the requirements in the FASB ASC with the SEC's regulations. The Company is currently evaluating ASU 2023-06 to determine its impact on the Company's consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). The standard enhances transparency in income tax disclosures by requiring, on an annual basis, certain disaggregated information about a reporting entity’s effective tax rate reconciliation and income taxes paid. The ASU also requires disaggregated disclosure related to pre-tax income (or loss) and income tax expense (or benefit) and eliminates certain disclosures related to the balance of an entity’s unrecognized tax benefit and the cumulative amount of certain temporary differences. The ASU is effective for the Company beginning on January 1, 2025. The Company is currently evaluating ASU 2023-09 to determine its impact on the Company's disclosures.

Income Taxes

In accordance with ASC 270, Interim Reporting, and ASC 740, Income Taxes, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate, apply that rate in providing for income taxes on a current year-to-date (interim period) basis, and include the tax impact for discrete items within the interim period. The Company maintains a full valuation allowance against all deferred tax assets as of June 30, 2024 and December 31, 2023, as management has determined that it is not more likely than not that the Company will realize these future tax benefits. As of June 30, 2024 and December 31, 2023, the Company had no uncertain tax positions.

8. Equity-based Compensation

2021 Equity Incentive Plan

On October 7, 2021, the date upon which the Company’s Registration Statement on Form S-1 in connection with the IPO was declared effective, the Company’s 2021 Equity Incentive Plan (the “2021 Plan”) became effective. On the same date, the Company ceased granting awards under its 2017 Equity Incentive Plan (the “2017 Plan”). The 2021 Plan authorizes the award of both equity-based and cash-based incentive awards, including: (i) stock options (both incentive stock options and nonqualified stock options), (ii) stock appreciation rights, (iii) restricted stock awards, (iv) restricted stock units (“RSUs”), and (v) cash or other stock-based awards. Incentive stock options may be granted only to employees. All other types of awards may be issued to employees, directors, consultants, and other service providers.

As of June 30, 2024, the aggregate number of shares of common stock of the Company that may be issued under the 2021 Plan is 2,582,736. The number of shares reserved for issuance under the 2021 Plan increased automatically on January 1, 2024 pursuant to an evergreen provision therein by 643,309 shares, representing 2% of total common shares outstanding at December 31, 2023. The aggregate number of shares will increase each anniversary of such date prior to the termination of the 2021 Plan, equal to the lesser of (i) 5% of the Company’s shares of common stock issued and outstanding on the last day of the immediately preceding fiscal year and (ii) such smaller number of shares as determined by the Company’s board of directors or the compensation committee. No more than 7,543,185 shares of common stock may be issued under the 2021 Plan through incentive stock options. Shares subject to the 2021 Plan, the 2017 Plan or the 2007 Equity Incentive Plan (the “2007 Plan” and collectively with the 2017 Plan, the “Prior Plans”) that expire, terminate

Table of Contents

or are cancelled or forfeited for any reason after the effectiveness of the 2021 Plan will be added (or added back) to the shares available for issuance under the 2021 Plan. The total number of shares underlying the Prior Plan awards that may be recycled into the 2021 Plan will not exceed 4,334,131 shares.

2017 Equity Incentive Plan

On September 15, 2017, the Company’s board of directors approved the 2017 Plan, which provides for the granting of incentive stock options, non-qualified stock options and stock awards to employees, certain consultants and directors. The board of directors, or its designated committee, has the sole authority to select the individuals to whom awards are granted and determine the terms of each award, including the number of shares and the schedule upon which the award becomes exercisable. Upon the effectiveness of the 2021 Plan, no further awards will be granted under the 2017 Plan.

The aggregate number of shares of common stock of the Company that may be issued under the 2017 Plan is 4,334,131 (taking into account shares of common stock that may become issuable pursuant to Section 3(b) of the 2017 Plan in respect of shares of common stock reserved under the Company’s Amended and Restated 2007 Equity Incentive Plan). The 2021 Plan provides for shares granted under the Prior Plans which are cancelled, forfeited, exchanged or surrendered without having been exercised shall subsequently be available for reissuance under the 2021 Plan.

Employee Stock Purchase Plan

The Company’s board of directors approved the Employee Stock Purchase Plan (the “ESPP”) prior to the closing of the IPO. Under the ESPP, the Company may provide employees and employees of the Subsidiary with an opportunity to purchase shares of the Company’s common stock at a discounted purchase price. As of June 30, 2024, subject to adjustment as provided in the ESPP, a total of 209,532 shares of common stock are authorized and reserved for issuance under the ESPP.

Subject to prior approval by the board of directors in each instance, on or about January 1, 2022 and each anniversary of such date thereafter prior to the termination of the ESPP, the number of shares of common stock authorized and reserved for issuance under the ESPP will be increased by a number of shares of common stock equal to the least of (i) 1,000,000 shares of common stock, (ii) 1% of the shares of common stock outstanding on the final day of the immediately preceding calendar year, and (iii) such smaller number of shares of common stock as determined by the board of directors. Such shares of common stock may be newly issued shares, treasury shares or shares acquired on the open market. In the event that any dividend or other distribution (whether in the form of cash, our common stock, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, or exchange of common stock or other securities, or other change in the structure affecting common stock occurs, then in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the ESPP, the compensation committee will, in such manner as it deems equitable, adjust the number of shares and class of common stock that may be delivered under the ESPP, the purchase price per share and the number of shares covered by each outstanding option under the ESPP, and the numerical limits described above.

Stock Options

The fair value of options granted was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:


	Six Months Ended June 30,
	2024	2023
Expected volatility	91.78% – 92.29%	91.53% – 92.68%
Risk-free interest rate	4.23% – 4.45%	3.46% – 4.21%
Dividend yield	0%	0%
Expected term (years)	6.10 – 6.20	6.18 – 6.36

Table of Contents

Expected Term — The expected term represents the period that the stock-based awards are expected to be outstanding. As the Company does not have sufficient historical experience for determining the expected term of the stock option awards granted, expected term has been calculated using the simplified method.

Risk-Free Interest Rate — The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant for zero-coupon U.S. Treasury constant maturity notes with terms approximately equal to the stock-based awards’ expected term.

Expected Volatility — Up until October 13, 2021, the Company was privately held and did not have a trading history of common stock. As such, the expected volatility was derived from the average historical stock volatilities of the common stock of several public companies within the industry that the Company considers to be comparable to our business over a period equivalent to the expected term of the stock-based awards. The Company will continue to derive expected volatility from average historical stock volatilities of industry peers until the Company has compiled a trading history of its own for a sufficient period of time.

Dividend Yield — The expected dividend yield is zero as the Company has not paid and does not anticipate paying any dividends in the foreseeable future.

Fair Value of Common Stock — Prior to the IPO, the fair value of the shares of common stock underlying the stock-based awards had historically been determined by the board of directors with input from management. Because there was no public market for the common stock, the board of directors had determined the fair value of the common stock at the time of grant of the stock-based award by considering a number of objective and subjective factors, including having contemporaneous valuations of the common stock performed by a third-party valuation specialist. Subsequent to the IPO, the board of directors determined the fair value of the shares of common stock underlying the stock-based awards based off of the closing price as reported on the Nasdaq Stock Market LLC on the grant date.

Activity for options was as follows:


	Options Outstanding
						Weighted-Average
				Aggregate		Remaining
	Number of	Weighted-Average		Intrinsic Value		Contractual Life
	Options	Exercise Price		(in 000’s)		(In Years)

Exercisable as of June 30, 2024	3,492,857	$	5.04	$	1,095	5.7

The weighted-average grant date fair value of stock options granted was $1.54 and $1.56 during the three and six months ended June 30, 2024, respectively. The weighted-average grant date fair value of stock options granted was $1.57 and $1.61 during the three and six months ended June 30, 2023, respectively. There were 42,500 and 247,500 stock options granted at an aggregate fair value of $65 and $385 for the three and six months ended June 30, 2024, respectively. There were 163,549 and 576,269 stock options granted at an aggregate fair value of $257 and $925 for the three and six months ended June 30, 2023, respectively. During the three and six months ended June 30, 2024, there were 73,350 stock options exercised, with an aggregate grant date fair value of $46, for each respective period. During the three and six months ended June 30, 2023, there were no stock options exercised. The intrinsic value of stock options exercised during the three and six months ended June 30, 2024 was $91, for each respective period.

Table of Contents

Restricted Stock Units

The fair values of RSUs are based on the fair market value of the Company’s common stock on the date of grant. Each RSU represents a contingent right to receive one share of the Company’s common stock upon vesting. RSUs with time base vesting conditions for employees vest annually over three or four years on each anniversary of the Grant Date and RSUs for non-employee directors vest on the one-year anniversary of the Grant Date. RSUs with performance conditions for employees vest on the one-year anniversary of the performance achievement date. During the three and six months ended June 30, 2024, the Company granted 42,500 and 838,700, respectively, RSU awards containing performance and time based vesting conditions to employees. As of June 30, 2024, the Company determined that the achievement of the performance target was probable and therefore, recognized expense for these awards during the three and six months ended June 30, 2024. The following table summarizes the Company’s RSU activity for the six months ended June 30, 2024:


	Number of	Weighted-Average
	Restricted Stock Units	Grant Date Fair Value
Outstanding at December 31, 2023	522,155	$	2.07
Granted	838,700	$	1.98
Vested	(182,482)	$	2.17
Forfeited	(8,125)	$	2.25
Outstanding at June 30, 2024	1,170,248	$	1.92

Equity-based Compensation Expense

The Company recorded total equity-based compensation expense in the statement of operations and comprehensive loss related to stock options and restricted stock units as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Research and development	$	282	$	156	$	513	$	313
General and administrative		865		869		1,805		1,899

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial conditions and results of operations should be read together with our consolidated financial statements and related notes appearing elsewhere in this Quarterly Report and our audited financial statements and notes thereto as of and for the years ended December 31, 2023 and 2022 and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report filed with the Securities and Exchange Commission (“SEC”), on March 26, 2024. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions and other factors that could cause actual results to differ materially from those made, projected or implied in the forward-looking statements. Our actual results may differ materially from those discussed below. Please see “Special Note Regarding Forward-Looking Statements” and “Risk Factors” included in Part I, Item 1A of our Annual Report for factors that could cause or contribute to such differences.

Overview

We are a clinical-stage biopharmaceutical company engaged in the discovery and development of innovative, small molecule therapeutics targeting age-related degenerative diseases and disorders of the central nervous system (“CNS”) and retina. Currently available therapies for these diseases are limited, with few Alzheimer’s disease (“AD”) treatments, two approved treatments for geographic atrophy (“GA”) secondary to dry age-related macular degeneration (“dAMD”) and no approved treatments for dementia with Lewy bodies. Our goal is to develop disease-modifying treatments for participants with these degenerative disorders by initially leveraging our expertise in the σ-2 (sigma-2) receptor (“S2R”), which is expressed by multiple cell types, including neuronal synapses, and acts as a key regulator of cellular damage commonly associated with certain age-related degenerative diseases of the CNS and retina. Data indicates that CT1812 antagonizes the binding and toxicity of amyloid beta oligomers via targeting the S2R complex and represents a mechanism that is functionally distinct from other current approaches in clinical development for the treatment of degenerative diseases. Clinical results support this hypothesis, and our clinical trial findings provide evidence that the displacement of oligomers from synapses via CT1812 engagement with the S2R results in improved synapse function.

In the SNAP study, results of which were published in May 2023 in the journal, Translational Neurodegeneration and showed that a single oral dose of CT1812 rapidly displaces Aβ oligomers from synapses of individuals with AD. In the SEQUEL study, top-line results showed that four weeks of treatment with CT1812 improved synapse activity and connectivity of brain regions as measured via quantitative electroencephalogram (“qEEG”). In blinded and unblinded clinical trials, several participants experienced asymptomatic, reversible elevations in serum liver chemistries prompting harmonization of monitoring, increasing frequency where appropriate, across our clinical trials.

In July 2024, we reported results from our Phase 2 SHINE trial, which showed a consistent trend in cognitive improvement in participants treated with CT1812 (pooled 100mg and 300mg) compared to placebo across all cognitive measures including ADAS-Cog 11, ADAS-Cog 13, cognitive composite and Mini-Mental State Examination scores. In addition, there were signals of improvement in functional measures (ADCS-ADL and ADCS-CGIC).

SHINE enrolled 153 adults with mild-to-moderate (MMSE 18-26) Alzheimer's disease who were randomized evenly (1:1:1) to one of two oral daily doses of CT1812 (100mg or 300mg) or placebo. P-values less than 0.05 were observed on ADAS-Cog 11 and MMSE at Day 98, the midpoint of the study. Through the course of the study, participants in the placebo arm worsened approximately 2.70 points as measured by ADAS-Cog 11 on Day 182. In contrast, CT1812-treated participants declined by an average of 1.66 points, a 39% slowing of decline favoring CT1812. Similar results were seen in the MMSE score on Day 98 for the pooled CT1812 arms. On the exploratory measures of function (ADCS-ADL and CGIC), there was a signal of benefit favoring CT1812 at the six-month timepoint. In the SHINE trial, CT1812 did not achieve statistical significance on the first of the ordered secondary efficacy endpoints in the pooled 100mg and 300mg dose group compared to placebo. The SHINE trial achieved its primary objective and demonstrated a favorable safety and tolerability profile, consistent with previous clinical experience. The percentage of participants experiencing any adverse event was similar between the pooled CT1812 treatment arms (76.5%) and the placebo group (78%). The majority of adverse events were mild or moderate in severity. In the placebo arm, 10% of participants experienced a serious adverse event (“SAE”) compared to approximately 5% in the combined CT1812 treated arms. Among CT1812-treated participants, two experienced treatment-emergent SAEs in the 100mg group, including stomatitis, chronic constipation, and hip fracture

(all deemed not related to treatment) and three experienced treatment-emergent SAEs in the 300mg group, including hematuria, abdominal pain, and infection (all deemed not related to treatment) and recurrent presyncope (deemed related to treatment). At the 300mg dose, nine participants experienced treatment-emergent liver enzyme test (“LFT”) increases (greater than 3xULN), which subsided after cessation of drug without evidence of serious liver injury. There were no LFT elevations observed in the 100mg dose.

We have enrolled 130 patients in the Phase 2 COG1201 (SHIMMER) study of CT1812 in mild-to-moderate dementia with Lewy bodies, or DLB. The design of this trial is a double-blind, randomized, six-month trial involving three dose groups, two active treatment cohorts and a placebo group. Clinical endpoints of the trial include safety and physical activity measurements, cognitive assessments, and PK and pharmacodynamic biomarker analyses compared to baseline measurements recorded at the beginning of the trial. In addition, cerebrospinal fluid will be collected and analyzed for α-synuclein content and established patterns of differential protein expression. This study is not powered to show significance in the efficacy endpoints. We expect to report topline results from our SHIMMER trial by year-end 2024.

Since our inception in 2007, we have incurred significant operating losses and devoted substantially all of our time and resources to developing our lead product candidate, CT1812, building our intellectual property portfolio, raising capital and recruiting management and technical staff to support these operations. As of June 30, 2024, we had an accumulated deficit of $157.4 million. We incurred a net loss of $7.0 million and $16.2 million for the three and six months ended June 30, 2024, respectively, and net loss of $4.7 million and $10.9 million for the three and six months ended June 30, 2023, respectively.

To date, we have funded our operations primarily with proceeds from grants awarded by the National Institute of Aging (the “NIA”), a division of the National Institutes of Health (the “NIH”), and proceeds from our initial public offering (the “IPO”), completed in October 2021, proceeds from our follow-on public offerings, sales of our common stock through our ATM (as defined below), sales of our convertible promissory notes, convertible preferred stock, simple agreements for future equity (“SAFE”) and stock option exercises. Since our inception, we have received approximately $171.0 million in cumulative grant awards to fund our clinical trials, primarily from the NIA, and we have raised approximately $125.9 million in net proceeds from sales of our equity securities, convertible notes, SAFE, stock option exercises, IPO and follow-on public offerings, ATM, and equity line financing with Lincoln Park. As of June 30, 2024, we had cash and cash equivalents of $28.5 million. To date, $57.3 million of the cumulative grant funds remain available.

On December 23, 2022, we entered into a sales agreement with Cantor Fitzgerald & Co. and B. Riley Securities, Inc. (the “Sales Agents”), providing for the offering, issuance and sale by us of up to $40.0 million of our common stock from time to time in “at-the-market” offerings (the “ATM”). We sold 191,273 shares of common stock under the ATM during the six months ended June 30, 2024 for gross proceeds of approximately $0.4 million. As of June 30, 2024, there was approximately $34.3 million of common stock remaining available for sale under the ATM.

On March 10, 2023, we entered into a purchase agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) for an equity line financing (the “Lincoln Park Purchase Agreement”). The Lincoln Park Purchase Agreement provides that, subject to the terms and conditions set forth therein, we have the right, but not the obligation, to direct Lincoln Park to purchase up to $35.0 million of shares of common stock at our sole discretion, over a 36-month period commencing on March 10, 2023. We filed a prospectus supplement to our registration statement on Form S-3 (File No. 333-268992) covering the resale of shares of common stock that are issued under the Lincoln Park Purchase Agreement. During the six months ended June 30, 2024, we did not sell any shares of common stock to Lincoln Park. As of June 30, 2024, $34.8 million was available to draw pursuant to the Lincoln Park Purchase Agreement.

On March 14, 2024, we completed our follow-on public offering, pursuant to which we issued and sold 6,571,428 shares of our common stock at a public offering price of $1.75 per share. On March 28, 2024, the underwriters exercised their option to purchase 985,714 shares of our common stock at a public offering price of $1.75 per share. In connection with the follow-on public offering, we received net proceeds of approximately $11.9 million, after deducting underwriting discounts and commissions and other offering related expenses.

and drug supply, seek regulatory approval for our current and future product candidates, maintain and expand our intellectual property portfolio, hire additional research and development and business personnel and operate as a public company. We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. In addition, if we obtain regulatory approval for our product candidates and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, manufacturing and distribution activities.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of public or private equity offerings, debt financings or other sources, such as potential collaboration agreements and strategic alliances, licensing or similar arrangements with third parties. To the extent available, we expect to continue our pursuit of non-dilutive research contributions, or grants, including additional NIA grant funding. However, we may fail to receive additional NIA grants, or we may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our failure to obtain additional NIA grants or raise capital or enter into such agreements as and when needed could have a material adverse effect on our business, results of operations and financial condition.

Because of the numerous risks and uncertainties associated with product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to raise capital, maintain our research and development efforts, expand our business or continue our operations at planned levels, and as a result we may be forced to substantially reduce or terminate our operations.

We do not own or operate manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of CT1812 for preclinical studies and clinical trials, as well as for commercial manufacture if CT1812 obtains marketing approval. We also rely, and expect to continue to rely, on third parties to manufacture, package, label, store, and distribute CT1812, if marketing approval is obtained. We believe that this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment, and personnel while also enabling us to focus our expertise and resources on the development of CT1812.

Impact of COVID-19 on Our Business

Our business has been and could be adversely affected by the effects of the COVID-19 pandemic or other national health issues. For example, our ongoing and/or planned clinical trials may be impacted by interruptions or delays at clinical trial sites or operations of the FDA and comparable foreign regulatory authorities. Additionally, we have made certain adjustments to the operation of our trials in an effort to ensure the monitoring and safety of participants and minimize risks to trial integrity during the pandemic in accordance with the guidance issued by the FDA and may need to make further adjustments in the future.

While the potential further economic impact brought by the COVID-19 pandemic may be difficult to assess or predict, there could be a significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity and financial position. As a result, we may face difficulties raising capital through future sales of our common stock or such sales may be on unfavorable terms.

Components of Our Results of Operations

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of direct and indirect costs incurred for our research activities, including development of our drug discovery efforts and the development of our product candidates. Direct costs include

Table of Contents

laboratory materials and supplies, contracted research and manufacturing, clinical trial costs, consulting fees, and other expenses incurred to sustain our research and development program. Indirect costs include personnel-related expenses, consisting of employee salaries, related benefits, and stock-based compensation expense for employees engaged in research and development activities, facilities, and other expenses consisting of direct and allocated expenses for rent and depreciation, and lab consumables.

We expense research and development costs as incurred. Non-refundable advance payments for goods and services that will be used over time for research and development are capitalized and recognized as goods are delivered or as the related services are performed. In-licensing fees and other costs to acquire technologies used in research and development that have not yet received regulatory approval and that are not expected to have an alternative future use are expensed when incurred. We track direct costs by stage of program, clinical or preclinical. However, we do not track indirect costs on a program specific basis because these costs are deployed across multiple programs and, as such, are not separately classified.

We cannot reasonably determine the nature, timing, and estimated costs of the efforts that will be necessary to complete the development of, and obtain regulatory approval for, any of our product candidates. Product candidates in later stages of development generally have higher development costs than those in earlier stages. We expect that our research and development expenses will increase substantially for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates, as our product candidates advance into later stages of development, as we begin to conduct larger clinical trials, as we seek regulatory approvals for any product candidates that successfully complete clinical trials, as we expand our product pipeline, as we maintain, expand, protect and enforce our intellectual property portfolio, and as we incur expenses associated with hiring additional personnel to support our research and development efforts.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related costs, including employee salaries, related benefits, and stock-based compensation expense for our employees in the executive, finance and accounting, and other administrative functions. General and administrative expenses also include third-party costs such as legal costs, insurance costs, accounting, auditing and tax related fees, consulting fees and facilities and other expenses not otherwise included as research and development expenses. We expense general and administrative costs as incurred.

Other Income (Expense)

Grant Income

Grant income relates to the grants awarded from governmental bodies that are conditional cost reimbursement grants and are recognized as grant income as allowable costs are incurred and the right to payment is realized. The grants awarded relate to agreed upon direct and indirect costs for specific studies or clinical trials, which may include personnel and consulting costs, costs paid to contract research organizations (“CROs”), research institutions and /or consortiums involved in the grant, as well as facilities and administrative costs. These grants are cost plus fixed fee arrangements in which we are reimbursed for eligible direct and indirect costs over time, up to the maximum amount of each specific grant award. Only costs that are allowable under the grant award, certain government regulations and the NIH’s supplemental policy and procedure manual may be claimed for reimbursement, and the reimbursements are subject to routine audits from governmental agencies from time to time. As of June 30, 2024, the Company has been awarded grants with project periods that extend through May 31, 2027, subject to extension. Our clinical trials have been funded by approximately $171.0 million in cumulative grants awarded primarily by the NIA, which includes an approximately $81.0 million grant from the NIA to fund our Phase 2 (COG0203-START) study of CT1812 in participants with early-stage AD, an approximately $30.5 million grant from the NIA to fund our Phase 2 (COG0201-SHINE) study of CT1812 in participants with mild-to-moderate AD, and an approximately $29.5 million grant from the NIA to fund our Phase 2 (COG1201-SHIMMER) study of CT1812 in participants with dementia with Lewy bodies.

Liquidity and Capital Resources

Sources of Liquidity

To date, we have funded our operations primarily with proceeds from grants awarded by the NIA, and proceeds from the sales of our convertible promissory notes, convertible preferred stock, SAFE, stock option exercises, follow-on equity offerings, sales under our ATM and equity line financing, and our IPO. Since our inception, we have received grant awards primarily from the NIA in the aggregate amount of approximately $171.0 million and have raised approximately $125.9 million in net proceeds from sales of our equity securities, convertible notes and SAFE, stock option exercises, our ATM, our equity line financing with Lincoln Park, our IPO and our follow-on public offering. The net proceeds from our IPO, which closed on October 13, 2021, were approximately $44.2 million, after deducting underwriting discounts and commissions and other offering related expenses payable by us. On November 15, 2022, we closed our follow-on public offering, selling 5,000,000 shares of our common stock at a public offering price of $1.20 per share. The net proceeds were approximately $5.2 million, after deducting underwriting discounts and commissions and other offering related expenses payable by us. On December 23, 2022, we entered into a sales agreement with the Sales Agents, providing for the offering, issuance and sale by us of up to $40.0 million of our common stock from time to time in ATM offerings. As of June 30, 2024, we sold 3,050,347 shares of common stock under the ATM for gross proceeds of approximately $5.7 million. As of June 30, 2024, there was $34.3 million of common stock remaining available for sale under the ATM. In addition, in March 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park Capital Fund, LLC, or Lincoln Park, giving the Company the right, but not the obligation to sell to Lincoln Park up to $35.0 million worth of shares of our common stock. As of June 30, 2024, we have sold 125,000 shares of common stock to Lincoln Park for proceeds of $0.2 million, as part of the equity line financing arrangement. As of June 30, 2024, $34.8 million was available to draw pursuant to the Lincoln Park Purchase Agreement. On March 14, 2024, we closed a follow-on public offering of 6,571,428 shares of our common stock at a public offering price of $1.75 per share. As part of the follow-on offering, the underwriters exercised their option to purchase 985,714 shares of our common stock on March 28, 2024, at a public offering price of $1.75 per share. The net proceeds were approximately $11.9 million, after deducting underwriting discounts and commissions and other offering related expenses payable by us.

As of June 30, 2024, we had $28.5 million in cash and cash equivalents and have not generated positive cash flows from operations. Based on our current business plans, we believe that our existing cash and cash equivalents, and income from non-dilutive grants, will be sufficient for us to fund our operating expenses and capital expenditures into the second quarter of 2025, which assumes no usage from the remaining ATM nor the Lincoln Park Purchase Agreement. We have based these estimates on assumptions that may prove to be incorrect or require adjustment as a result of business decisions, and we could utilize our available capital resources sooner than we currently expect.

As of August 8, 2024, the date of issuance of this Quarterly Report, we believe that our cash and cash equivalents as of June 30, 2024 is not sufficient to fund operations for the period through one year after the date of this filing and therefore we have concluded that substantial doubt exists about our ability to continue as a going concern.

To execute our business plans, we will need substantial funding to support our continuing operations and pursue our growth strategy. Until such time that we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of common stock in public offerings and/or private placements, debt financings or other capital sources, including collaborations with other companies or other strategic transactions. There can be no assurance that additional financing will be available to us or that such financing, if available, will be available on terms acceptable to us. The terms of any financing may adversely affect the holdings or the rights of our stockholders. If we are unable to obtain funding, we could be forced to delay, reduce or abandon our product development programs, which could have a material adverse effect on our business prospects.

Future Funding Requirements

We expect to continue to incur significant and increasing expenses and net losses for the foreseeable future, as we advance our current and future product candidates through preclinical and clinical development, manufacture drug product and drug supply, seek regulatory approval for our current and future product candidates, maintain and expand our intellectual property portfolio, hire additional research and development and business personnel, and operate as a public

Table of Contents

company. We anticipate that we will need to raise additional funding in the future to fund our operations, including continuing and completing our clinical trials. We are subject to the risks typically related to the development of new products, and we may encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business.

Our future funding requirements will depend on many factors, including, but not limited to:

●

the scope, progress, costs and results of our ongoing and planned clinical trials of CT1812, as well as the associated costs, including any unforeseen costs we may incur as a result of preclinical study or clinical trial delays due to a pandemic, such as the COVID-19 pandemic or other diseases, macroeconomic conditions, global or political instability, such as the ongoing global and regional conflicts, inflation, or other delays;

●

the scope, progress, costs and results of preclinical development, laboratory testing and clinical trials for any future product candidates we may decide to pursue;

●

the extent to which we develop, in-license or acquire other product candidates and technologies;

●

the costs and timing of process development and manufacturing scale-up activities associated with our product candidates and other programs as we advance them through preclinical and clinical development;

●

the availability, timing, and receipt of any future NIA grants;

●

the number and development requirements of other product candidates that we may pursue;

●

the costs, timing and outcome of regulatory review of our product candidates;

●

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval;

●

the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

●

our ability to establish collaborations to commercialize CT1812 or any of our other product candidates outside the United States;

●

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; and

●

the additional costs we may incur as a result of operating as a public company, including our efforts to enhance operational systems and hire additional personnel, including enhanced internal controls over financial reporting.

Until such time as we can generate significant revenue from product sales, we expect to finance our operations through a combination of public or private equity offerings, debt financings or other sources, such as potential collaboration agreements and strategic alliances, licensing or similar arrangements with third parties. To the extent available, we expect to continue our pursuit of non-dilutive research contributions, or grants, including additional NIA grant funding. However, we may fail to receive additional NIA grants, or we may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our failure to obtain additional NIA grants or raise capital or enter into such agreements as and when needed could have a material adverse effect on our business, results of operations and financial condition.

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 preferred 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. If we raise funds through collaborations, licenses and other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research 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. Adequate funding may not be available when needed or on terms acceptable to us, or at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the COVID-19 pandemic or other diseases, the ongoing global and regional conflicts, inflation, liquidity constraints, failures and instability in U.S. and international financial banking systems, and otherwise. If we fail to obtain necessary capital when needed on acceptable terms, or at all, it could force us to delay, limit, reduce or terminate our product development programs, commercialization efforts or other operations. Insufficient liquidity may also require us to relinquish rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. We cannot assure you that we will ever be profitable or generate positive cash flows from operating activities.

Cash Flows

The following table summarizes our cash flows for the periods indicated (in thousands):


	Six Months Ended June 30,
	2024		2023
Cash flows used in operating activities	$	(13,241)	$	(6,401)
Cash flows used in investing activities		(3)		(59)

Effect of exchange rate changes on cash and cash equivalents		—		3
Net decrease in cash and cash equivalents	$	(1,389)	$	(4,372)

Operating Activities

Net cash used in operating activities for the six months ended June 30, 2024 was $13.2 million, which consisted primarily of a net loss of $16.2 million, offset primarily by the impact of equity-based compensation of $2.3 million and a net change of $0.3 million in operating assets and liabilities. The net change in operating assets and liabilities was primarily due to an increase in grant receivables of $1.8 million, an increase in accounts payable and accrued expenses of $1.3 million, a decrease in prepaid expenses and other assets of $1.1 million, and a decrease in deferred grant income and other liabilities of $0.3 million.

Net cash used in operating activities for the six months ended June 30, 2023, was $6.4 million, which consisted primarily of a net loss of $10.9 million, offset primarily by the impact of equity-based compensation of $2.2 million and a net change of $1.9 million in operating assets and liabilities. The net change in operating assets and liabilities was primarily due to a decrease in grant receivables of $1.3 million, a decrease in prepaid expenses and other assets of $0.8 million, an increase in accounts payable and accrued expenses of $1.2 million, and a decrease in deferred grant income and other liabilities of $1.3 million.

Investing Activities

Net cash used in investing activities for the six months ended June 30, 2024 and 2023 was less than $0.1 million and less than $0.1 million, respectively. Overall, the change in net cash used in investing activities was insignificant.

Financing Activities

Net cash provided by financing activities for the six months ended June 30, 2024 and 2023 was $11.9 million and $2.1 million, respectively. The change in net cash provided by financing activities is primarily related to net proceeds from the issuance of common stock in our follow-on offering in March 2024 and under the ATM program.

In October 2023, we entered into an insurance premium financing arrangement with a lender whereby we financed $0.7 million of certain premiums at a 8.65% annual interest rate. Payments of less than $0.1 million are due monthly from October 2023 through September 2024.

We have entered into an operating leases for office and laboratory facilities under agreements that run through May 31, 2029. The amounts reflected in the table above consist of the future minimum lease payments under the non-cancelable lease arrangements.

On August 31, 2022, we entered into an agreement to lease 2,980 square feet of office space in Pittsburgh, Pennsylvania. The lease has a term of 45 months and commenced on October 1, 2022. The annual base rent under the lease is less than $0.1 million throughout the term of the lease. Total payments due over the term of the lease are $0.2 million. Additionally, on August 31, 2022, we modified one of our existing lease agreements with the landlord for approximately 3,706 square feet of lab space at the same location to extend the lease term termination date from June 30, 2023 until June 30, 2026.

On July 1, 2021, we entered into an agreement to lease 2,864 square feet of office space in Purchase, New York. The lease has a term of 89 months and commenced on December 9, 2021. The annual base rent under the lease is less than $0.1 million for the first lease year and is subject to annual increases of between 1.82% and 2.04%. We provided a security deposit in the form of a Letter of Credit in the amount of less than $0.1 million pursuant to the terms of the lease.

We enter into contracts in the normal course of business with CROs and other vendors to assist in the performance of our research and development and other services and products for operating purposes. These contracts typically do not contain minimum purchase commitments and generally provide for termination on notice, and therefore are cancelable contracts and not included in the table of contractual obligations.

Critical Accounting Policies and Use of Estimates

The Critical Accounting Policies and Significant Judgements and Estimates included in our Annual Report on Form 10-K have not materially changed. See “Critical Accounting Policies and Use of Estimates” included in Part II, Item 7 of our Annual Report on Form 10-K filed with the SEC on March 26, 2024.

Recent Accounting Pronouncements

For a description of recent accounting pronouncements, see Note 2 of the notes to our consolidated financial statements included in this Quarterly Report.

Emerging Growth Company Status

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (1) are no longer an emerging growth company or (2) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Table of Contents

We will remain an emerging growth company until the earliest to occur of: (1) the last day of the fiscal year in which we have at least $1.235 billion in annual revenue; (2) the last day of the fiscal year in which we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year; (3) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period; and (4) the last day of the fiscal year ending after the fifth anniversary of our IPO.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

As a “smaller reporting company,” as that term is defined in Rule 229.10(f)(1), we are not required to provide the information required by this Item.

Item 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our President and Chief Executive Officer and our Chief Financial Officer have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act) as of the end of the period covered by this Quarterly Report. Based on this evaluation, our President and Chief Executive Officer and our Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our President and Chief Executive Officer and our Chief Financial Officer, to allow for timely decisions regarding required disclosures, and recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Management’s Report on Internal Controls over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over our financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting. Management has used the framework set forth in the report entitled “Internal Control—Integrated Framework (2013)” published by the Committee of Sponsoring Organizations of the Treadway Commission to evaluate the effectiveness of our internal control over financial reporting. Based on its evaluation, management has concluded that our internal control over financial reporting was effective as of June 30, 2024.

Changes in Internal Control

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our President and Chief Executive Officer and our Chief Financial Officer, does not expect that our disclosure controls and procedures or internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the system are met and cannot detect all deviations. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or deviations, if any, within the company have been detected. 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.

Table of Contents

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not aware of any pending legal actions that would, if determined adversely to us, have a material adverse effect on our business and operations.

We may, from time to time, become involved in disputes and proceedings arising in the ordinary course of business. In addition, as a public company, we are also potentially susceptible to litigation, such as claims asserting violations of securities laws. Any such claims, with or without merit, if not resolved, could be time-consuming and result in costly litigation. There can be no assurance that an adverse result in any future proceeding would not have a potentially material adverse effect on our business, results of operations, and financial condition.

Item 1A. Risk Factors

You should carefully consider the risk factors described in our Annual Report under the caption “Item 1A. “Risk Factors.” Other than as set forth below, there have been no material changes in our risk factors included in our Annual Report. The risks described in our Annual Report are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

There is substantial doubt about our ability to continue as a going concern.

Our management has concluded that, based on our current operating plan, there is substantial doubt as to whether we can continue as a going concern for the twelve months following the issuance of this Quarterly Report. To date, we have not generated any revenues from product sales and have incurred significant operating losses in each year since our inception and we anticipate that losses may continue for the next several years or until such time as we can generate substantial revenues and achieve profitability. As of June 30, 2024, we had $28.5 million in cash and cash equivalents and have not generated positive cash flows from operations. Based on our current business plans, we believe that our existing cash and cash equivalents, and income from non-dilutive grants, will be sufficient for us to fund our operating expenses and capital expenditures into the second quarter of 2025, which assumes no usage from the remaining ATM nor the Lincoln Park Purchase Agreement. Our ability to continue as a going concern is dependent upon raising capital to maintain current operations and continue research and development efforts. We plan to raise additional capital to fund our operations through public or private equity offerings, debt financings, and/or potential collaborations and license arrangement or other sources. There is no assurance, however, that any additional financing or any revenue-generating collaboration will be available when needed or that we will be able to obtain financing or enter into a collaboration on terms acceptable to us or at all. If such additional capital is not available on satisfactory terms, or is not available in sufficient amounts, or if we are unable to enter into a collaboration, we may be required to delay, limit or eliminate the development of CT1812 and our ability to achieve our business objectives, our competitiveness, and our business, financial condition and results of operations will be materially adversely affected.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Recent Sales of Unregistered Securities

There were no unregistered sales of our equity securities during the fiscal quarter ended June 30, 2024.

Use of Proceeds from our Initial Public Offering of Common Stock

Our registration statement on Form S-1 (File Nos. 333-257999 and 333-260128) relating to the IPO was declared effective by the SEC on October 7, 2021. There has been no material change in the planned use of proceeds from the IPO from that described in the prospectus, dated October 7, 2021, filed with the SEC pursuant to Rule 424(b) under the Securities Act.
