Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. General and Liquidity

Cassava Sciences, Inc. and its wholly-owned subsidiary (collectively referred to as the “Company”) discover and develop proprietary pharmaceutical product candidates that may offer significant improvements to patients and healthcare professionals. The Company generally focuses its discovery and product development efforts on disorders of the nervous system.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. All intercompany transactions and balances have been eliminated in consolidation. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management of the Company, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year 2022. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Coronavirus Disease 2019 (COVID-19)

The widespread outbreak of a novel infectious disease called Coronavirus Disease 2019, or COVID-19, and the impact of the omicron and other variants and subvariants of this disease, has not significantly impacted the Company’s operations or financial condition as of November 7, 2022. We believe certain investigational clinical study sites that are involved, or potentially would like to be involved, with our clinical programs may be experiencing lingering, pandemic-related after-effects, such as staffing shortages, operational gaps or other adverse circumstances. Also, this pandemic has created a dynamic and uncertain situation in the national economy. The Company continues to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on its operations and financial condition. The scope of pandemic is unprecedented, and its long-term impact on the Company’s operations and financial condition cannot be reasonably estimated at this time.

Liquidity

The Company has incurred significant net losses and negative cash flows since inception, and as a result has an accumulated deficit of $264.4 million at September 30, 2022. The Company expects its cash requirements to be significant in the future. The amount and timing of the Company’s future cash requirements will depend on regulatory and market acceptance of its product candidates and the resources it devotes to researching and developing, formulating, manufacturing, commercializing and supporting its products. The Company may seek additional funding through public or private financing in the future, if such funding is available and on terms acceptable to the Company. There are no assurances that additional financing will be available on favorable terms, or at all. However, management believes that the current working capital position will be sufficient to meet the Company’s working capital needs for at least the next 12 months.

Note 2.  Significant Accounting Policies

Use of Estimates

The Company makes estimates and assumptions in preparing its condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to manufacturing agreements and research collaborations. Actual results could differ from these estimates and assumptions.

7

Cash and Cash Equivalents and Concentration of Credit Risk

The Company invests in cash and cash equivalents. The Company considers highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered cash equivalents include money market accounts and funds, certificates of deposit, and U.S. Treasury securities. The Company maintains its cash and cash equivalents at one financial institution.

Fair Value Measurements

The Company recognizes financial instruments in accordance with the authoritative guidance on fair value measurements and disclosures for financial assets and liabilities. This guidance defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. The guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

Level 1 includes quoted prices in active markets.

Level 2 includes significant observable inputs, such as quoted prices for identical or similar securities, or other inputs that are observable and can be corroborated by observable market data for similar securities. The Company uses market pricing and other observable market inputs obtained from third-party providers. It uses the bid price to establish fair value where a bid price is available. The Company does not have any financial instruments where the fair value is based on Level 2 inputs.

Level 3 includes unobservable inputs that are supported by little or no market activity. The Company does not have any financial instruments where the fair value is based on Level 3 inputs.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The fair value of cash and cash equivalents was based on Level 1 inputs at September 30, 2022 and December 31, 2021.

Business Segments

The Company reports segment information based on how it internally evaluates the operating performance of its business units, or segments. The Company’s operations are confined to one business segment: the development of novel drugs and diagnostics.

Proceeds from Grants

During the three months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.4 million and $2.0 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the nine months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.9 million and $3.5 million pursuant to NIH research grants, respectively. The Company records the proceeds from these grants as reductions to its research and development expenses.

Stock-based Compensation 

The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. This model requires the input of subjective assumptions including expected stock price volatility, expected life and estimated forfeitures of each award. These assumptions consist of estimates of future market conditions, which are inherently uncertain, and therefore, are subject to management's judgment. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years.

The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit

8

service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria.

Net Loss per Share

The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options.  There is no difference between the Company’s net loss and comprehensive loss. The numerators and denominators in the calculation of basic and diluted net loss per share were as follows (in thousands, except net loss per share data):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Numerator:
Net loss	$	(20,257)	$	(9,562)	$	(57,112)	$	(18,213)
Denominator:
Shares used in computing net loss per share, basic and diluted		40,050		39,957		40,009		39,218
Net loss per share, basic and diluted	$	(0.51)	$	(0.24)	$	(1.43)	$	(0.46)
Dilutive common stock options excluded from net loss per share, diluted		1,946		2,350		2,064		2,219

The Company excluded common stock options outstanding, along with 57,143 restricted stock awards, from the calculation of net loss per share, diluted, because the effect of including outstanding options and warrants would have been anti-dilutive. The 57,143 restricted stock awards expired during the nine months ended September 30, 2022.

Fair Value of Financial Instruments   

Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments.

Research Contract Costs and Accruals

The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable. Related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs.

Incentive Bonus Plan

In 2020, the Company established the 2020 Cash Incentive Bonus Plan (the “Plan”) to incentivize Plan participants. Awards under the Plan are accounted for as liability awards under Accounting Standards Codification (ASC) 718 “Stock-based Compensation”. The fair value of each potential Plan award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each Plan award, when a Performance Condition (as defined below) is considered probable of being met. See Note 10 for further discussion of the Plan.

9

Leases

The Company recognizes assets and liabilities that arise from leases. For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments during the lease term, in the condensed consolidated balance sheets. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities. As the Company`s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Property and equipment

Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Owned buildings and related improvements have estimated useful lives of 39 years and approximately 10 years, respectively. Tenant improvements related to leased space are amortized using the straight-line method over the useful lives of the improvements or the remaining term of the corresponding leases, whichever is shorter. The remaining term of the corresponding leases is approximately 1.6 years.

Property and equipment are reviewed for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If property and equipment are considered to be impaired, an impairment loss is recognized.

Intangible assets

Acquired intangible assets are recorded at fair value at the date of acquisition and primarily consist of lease-in-place agreements and leasing commissions. Intangible assets are amortized over the estimated life of the lease-in-place agreements, which is approximately 1.5 years at September 30, 2022.

Intangible assets are reviewed for impairment on an annual basis, and when there is reason to believe that their values have been diminished or impaired. If intangible assets are considered to be impaired, an impairment loss is recognized.

Income Taxes 

The Company accounts for income taxes under the asset and liability method.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance.

The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s condensed consolidated financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.

Note 3. Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets at September 30, 2022 and December 31, 2021 consisted of the following (in thousands):

	September 30,		December 31,
	2022		2021
Prepaid insurance	$	1,308	$	662
Contract research organization and other deposits		7,223		10,330
Other		79		53
Total prepaid expenses and other current assets	$	8,610	$	11,045

Note 4. Real Property Acquisition

On August 4, 2021, the Company completed the all-cash purchase of a two-building office complex in Austin, Texas, a portion of which serves as its corporate headquarters. This property is intended to accommodate the Company’s anticipated growth and expansion of its operations in the coming years. Maintenance, physical facilities, leasing, property management and other key responsibilities related to property ownership are being outsourced to professional real-estate managers. The purchase price of the property was $22.0 million, including transaction costs. The office complex measures approximately 90,000 rentable square feet. At September 30, 2022, the property was over 60% leased. The Company also occupies approximately 25% of the property. The seller was a third party not affiliated with the Company.

The purchase was accounted for as an asset acquisition under ASC 805, Business Combinations. As substantially all of the fair value of the gross assets acquired were concentrated into a single identifiable asset, the Company concluded that the screen was met, and the transaction is considered an asset acquisition rather than an acquisition of a business. Pursuant to the cost accumulation method as prescribed in ASC 805, the cost of the acquisition, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. The value of acquired in-place leases was measured as the sum of lost revenues that would be incurred during a prospective lease-up period that would be necessary to achieve occupancy similar to that at the time of acquisition. The value was calculated as the average number of months of lease-up multiplied by the gross monthly market rental rate (base rent plus reimbursements) for each particular suite.

The assets acquired are summarized as follows (in thousands):

Land	$	3,734
Buildings		15,980
Site improvements		453
Tenant improvements		567
Total tangible assets	$	20,734
Lease-in-place agreements	$	1,053
Leasing commissions and other		246
Total intangible assets	$	1,299
Consideration paid	$	22,033

Note 7. Stockholders’ Equity and Stock-Based Compensation Expense

2021 Registered Direct Offering

On February 12, 2021, the Company completed a common stock offering pursuant to which certain investors purchased 4,081,633 shares of common stock at a price of $49.00 per share. Net proceeds of the offering were approximately $189.8 million after deducting offering expenses.

At-the-Market Common Stock Offering

In March 2020, the Company established an at-the-market offering program (“ATM”) to sell, from time to time, shares of Company common stock having an aggregate offering price of up to $100 million in transactions pursuant to a shelf registration statement that was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on May 5, 2020. The Company is obligated to pay a commission of 3.0% of the gross proceeds from the sale of shares of common stock in the offering. The Company is not obligated to sell any shares in the offering.

There were no common stock sales under the ATM during the three and nine months ended September 30, 2022 and 2021.

Common Stock Warrants

In August 2018, the Company issued warrants to purchase up to an aggregate of 9.1 million shares of its common stock in conjunction with an offering of its common stock. 

The Company did not receive any proceeds from exercise of common stock warrants during the three and nine months ended September 30, 2022.

The Company did not receive any proceeds from exercise of common stock warrants during the three months ended September 30, 2021. During the nine months ended September 30, 2021, the Company received proceeds of $0.7 million from the exercise of 0.6 million shares pursuant to warrants.

There were no common stock warrants outstanding as of September 30, 2022.

Stock Option and Performance Award Activity in 2022

During the nine months ended September 30, 2022, stock options and unvested Performance Awards outstanding under the Company’s stock option plans changed as follows:

	Stock Options	Performance Awards
Outstanding as of December 31, 2021	2,663,727	138,055
Options granted	4,000	—
Options exercised	(194,264)	—
Options forfeited/canceled	(22,139)	(130,913)
Outstanding as of September 30, 2022	2,451,324	7,142

The weighted average exercise price of options outstanding at September 30, 2022 was $11.03. As outstanding options vest over the current remaining vesting period of 1.7 years, the Company expects to recognize stock-based

13

compensation expense of $4.9 million. If and when outstanding Performance Awards vest, the Company will recognize stock-based compensation expense of $0.1 million over the implicit service period.

During the three months ended September 30, 2022, there were 18,740 stock options exercised with cash proceeds to the Company totaling $136,000.

During the nine months ended September 30, 2022, there were 194,264 stock options exercised. Of the stock options exercised, 94,399 stock options were net settled in satisfaction of the exercise price, with no cash proceeds received. Cash proceeds to the Company for options not net settled totaled $466,000 during the nine months ended September 30, 2022.

During the nine months ended September 30, 2022, a total of 57,143 shares of restricted stock awards expired as performance criteria related to these Performance Awards were not attained. These shares of restricted stock were returned to the 2008 Equity Incentive Plan, which expired in December 2017, and thus were retired.

Stock-based Compensation Expense in 2022

During the three and nine months ended September 30, 2022 and 2021, the Company’s stock-based compensation expense was as follows (in thousands):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Research and development	$	399	$	452	$	1,234	$	867
General and administrative		71		120		216		370
Total stock-based compensation expense	$	470	$	572	$	1,450	$	1,237

2018 Equity Incentive Plan

The Company’s Board of Directors (the “Board”) or a designated committee of the Board is responsible for administration of the Company’s 2018 Omnibus Incentive Plan, as amended (the “2018 Plan”) and determines the terms and conditions of each option granted, consistent with the terms of the 2018 Plan. The Company’s employees, directors, and consultants are eligible to receive awards under the 2018 Plan, including grants of stock options and Performance Awards. Share-based awards generally expire 10 years from the date of grant. The 2018 Plan, as amended on May 5, 2022, provides for issuance of up to 5,000,000 shares of common stock, par value $0.001 per share, subject to adjustment as provided in the 2018 Plan.

When stock options or Performance Awards are exercised net of the exercise price and taxes, the number of shares of stock issued is reduced by the number of shares equal to the amount of taxes owed by the award recipient and that number of shares are cancelled. The Company then uses its cash to pay tax authorities the amount of statutory taxes owed by and on behalf of the award recipient.

Note 8. Income Taxes

The Company did not provide for income taxes during the three and nine months ended September 30, 2022, because it has projected a net loss for the full year 2022 for which any benefit will be offset by an increase in the valuation allowance. There was also no provision for income taxes for the three and nine months ended September 30, 2021.

Note 9. Commitments

Right-of-use Asset and Liability

The Company has an operating lease for approximately 6,000 square feet of office space in Austin, Texas that expires on April 30, 2024. The Company also had a short-term lease agreement for an additional 3,600 square feet of office space in Austin, Texas that expired on October 31, 2022. Future expected minimum lease payments as of September 30, 2022 are as follows (in thousands):

		2022	2023	2024	Total future lease payments	Less: imputed interest		Total
Operating leases	$	27	107	36	170	(6)	$	164
Short-term operating lease	$	6	—	—	6	—	$	6

Rent expense for the three months ended September 30, 2022 and 2021 totaled $41,000 for each period.

Rent expense for the nine months ended September 30, 2022 and 2021 totaled $123,000 and $98,000, respectively.

Cash paid for operating lease liabilities during the three months ended September 30, 2022 and 2021 totaled $42,000 and $41,000, respectively.

Cash paid for operating lease liabilities during the nine months ended September 30, 2022 and 2021 totaled $124,000 and $68,000, respectively.

Other Commitments

 The Company conducts its product research and development programs through a combination of internal and collaborative programs that include, among others, arrangements with universities, contract research organizations and clinical research sites. The Company has contractual arrangements with these organizations that are cancelable. The Company’s obligations under these contracts are largely based on services performed.

Note 10.  2020 Cash Incentive Bonus Plan

In August 2020, the Board approved the Plan. The Plan was established to promote the long-term success of the Company by creating an “at-risk” cash bonus program that rewards Plan participants with additional cash compensation in lockstep with significant increases in the Company’s market capitalization. The Plan is considered “at-risk” because Plan participants will not receive a cash bonus unless the Company’s market capitalization increases significantly and certain other conditions specified in the Plan are met. Specifically, Plan participants will not be paid any cash bonuses unless (1) the Company completes a merger or acquisition transaction that constitutes a sale of ownership of the Company or its assets (a Merger Transaction) or (2) the Compensation Committee of the Board (the Compensation Committee) determines the Company has sufficient cash on hand, as defined in the Plan. Because of the inherent discretion and uncertainty regarding these requirements, the Company has concluded that a Plan grant date has not occurred as of September 30, 2022.

Plan participants will be paid all earned cash bonuses in the event of a Merger Transaction.

The Company’s market capitalization for purposes of the Plan is determined based on either (1) the closing price of one share of the Company’s common stock on the Nasdaq Capital Market multiplied by the total issued and outstanding shares and options to purchase shares of the Company, or (2) the aggregate consideration payable to security holders of the Company in a Merger Transaction. This constitutes a market condition under applicable accounting guidance.   

The Plan triggers a potential cash bonus each time the Company’s market capitalization increases significantly, up to a maximum $5 billion in market capitalization. The Plan specifies 14 incremental amounts between $200 million and $5 billion (each increment, a “Valuation Milestone”). Each Valuation Milestone triggers a potential cash bonus

15

award in a pre-set amount defined in the Plan. Each Valuation Milestone must be achieved and maintained for no less than 20 consecutive trading days for Plan participants to be eligible for a potential cash bonus award. Approximately 58% of each cash bonus award associated with a Valuation Milestone is subject to adjustment and approval by the Compensation Committee. Any amounts not awarded by the Compensation Committee are no longer available for distribution.

If the Company were to exceed a $5 billion market capitalization for no less than 20 consecutive trading days, all Valuation Milestones would be deemed achieved, in which case cash bonus awards would range from a minimum of $139.1 million up to a hypothetical maximum of $322.3 million. Payment of cash bonuses is deferred until such time as (1) the Company completes a Merger Transaction, or (2) the Compensation Committee determines the Company has sufficient cash on hand to render payment (each, a “Performance Condition”), neither of which may ever occur. Accordingly, there can be no assurance that Plan participants will ever be paid a cash bonus that is awarded under the Plan, even if the Company’s market capitalization increases significantly.

The Plan is accounted for as a liability award. The fair value of each Valuation Milestone award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each of the 14 Valuation Milestones, when a Performance Condition is considered probable of being met.   

In October 2020, the Company achieved the first Valuation Milestone. Subsequently, the Compensation Committee approved a potential cash bonus award of $7.3 million in total for all Plan participants, subject to future satisfaction of a Performance Condition.

During the year ended December 31, 2021, the Company achieved 11 additional Valuation Milestones triggering potential Company obligations to all Plan participants from a minimum of $93.7 million up to a hypothetical maximum of $225.0 million, to be determined by the Compensation Committee and contingent upon future satisfaction of a Performance Condition. However, no compensation expense was recorded since no grant date has occurred and no Performance Conditions are considered probable of being met. There is no continuing service requirement for Plan participants once the Compensation Committee approves a cash bonus award.

No Valuation Milestones were achieved during the three and nine months ended September 30, 2022.

No actual cash payments were authorized or made to participants under the Plan through November 7, 2022.

Note 11. Contingencies

Securities Class Actions and Shareholder Derivative Actions

Between August 27, 2021 and October 26, 2021, four putative class action lawsuits were filed alleging violations of the federal securities laws by the Company and certain named officers. The complaints rely on allegations contained in Citizen Petitions submitted to FDA, and allege that various statements made by the defendants regarding simufilam were rendered materially false and misleading. The Citizen Petitions were all subsequently denied by FDA. These actions were filed in the U.S. District Court for the Western District of Texas. The complaints seek unspecified compensatory damages and other relief on behalf of a purported class of purchasers of the Company’s securities. On June 30, 2022, a federal judge consolidated the four class action lawsuits into one case and appointed a lead plaintiff and a lead counsel. Lead plaintiff filed a consolidated amended complaint on August 18, 2022 on behalf of a putative class of purchasers of the Company’s securities between September 14, 2020 and July 26, 2022. Briefing on defendants’ motion to dismiss is scheduled to be completed by January 23, 2023. The Company believes the claims are without merit and intends to defend against these lawsuits vigorously. The Company is unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

On November 4, 2021, a related shareholder derivative action was filed, purportedly on behalf of the Company, in the U.S. District Court for the Western District of Texas, asserting claims under the U.S. securities laws and state fiduciary duty laws against certain named officers and the members of the Company’s board of directors. This

16

complaint relies on the allegations made in Citizen Petitions that were submitted to (and subsequently denied by) FDA. The complaint alleges, among other things, that the individual defendants exposed the Company to unspecified damages and securities law liability by causing it to make materially false and misleading statements, in violation of the U.S. securities laws and in breach of their fiduciary duties to the Company. The derivative case seeks, among other things, to recover unspecified compensatory damages on behalf of the Company arising out of the individual defendant’s alleged wrongful conduct. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants. Since November 4, 2021, three additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, and one in Texas state court (Travis County District Court). All four actions have been stayed pending the resolution of the motions to dismiss in the securities class actions. On July 5, 2022, the three federal court actions were consolidated into a single action.

On August 19, 2022, a shareholder derivative action was filed, purportedly on behalf of the Company, in the Delaware Court of Chancery, asserting claims under state fiduciary duty laws against certain named officers and members of the Company’s board of directors. The complaint alleges, among other things, that the individual defendants breached their fiduciary duties by approving the 2020 Cash Incentive Bonus Plan in August 2020. The complaints seek unspecified compensatory damages and other relief. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants.

The Company is unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

We do not intend to update any forward-looking statement, whether written or oral, relating to the matters discussed in this Quarterly Report on Form 10-Q, except as required by law.

Our research programs in neurodegeneration benefit from longstanding scientific and financial support from the National Institutes of Health (“NIH”). The contents of this Quarterly Report on Form 10-Q are solely our responsibility and do not necessarily represent any official views of NIH.

Overview

Cassava Sciences, Inc. is a clinical-stage biotechnology company based in Austin, Texas. Our mission is to detect and treat neurodegenerative diseases, such as Alzheimer’s disease. Our novel science is based on stabilizing – but not removing – a critical protein in the brain.

Over the past 10 years, we have combined state-of-the-art technology with new insights in neurobiology to develop novel solutions for Alzheimer’s disease and other neurodegenerative diseases. Our strategy is to leverage our unique scientific/clinical platform to develop a first-in-class program for treating neurodegenerative diseases, such as Alzheimer’s.

We currently have two biopharmaceutical assets under development:

our lead therapeutic product candidate, called simufilam, is a novel treatment for Alzheimer’s disease; and

our lead investigational diagnostic product candidate, called SavaDx, is a novel way to detect the presence of Alzheimer’s disease from a small sample of blood.

Our scientific approach for the treatment of Alzheimer’s disease seeks to simultaneously suppress both neurodegeneration and neuroinflammation. We believe our ability to improve multiple vital functions in the brain represents a new, different and crucial approach to address Alzheimer’s disease.

Our lead therapeutic product candidate, simufilam, is a proprietary small molecule (oral) drug. Simufilam targets an altered form of a protein called filamin A (FLNA) in the Alzheimer’s brain. Published studies have demonstrated that the altered form of FLNA causes neuronal dysfunction, neuronal degeneration and neuroinflammation. We are currently conducting a Phase 3 program with simufilam in patients with mild-to-moderate Alzheimer’s disease dementia.

19

We believe simufilam improves brain health by reverting altered FLNA back to its native, healthy conformation, thus countering the downstream toxic effects of altered FLNA. We have generated and published experimental and clinical evidence of improved brain health with simufilam. Importantly, simufilam is not dependent on clearing amyloid from the brain. Since simufilam has a unique mechanism of action, we believe its potential therapeutic effects may be additive or synergistic with those of other therapeutic candidates aiming to treat neurodegeneration.

Simufilam has demonstrated a multitude of treatment effects in animal models of disease, including normalizing neurotransmission, decreasing neuroinflammation, suppressing neurodegeneration, and restoring memory and cognition.

Simufilam and SavaDx were both discovered and designed in-house and were characterized by our academic collaborators during research activities that were conducted from approximately 2008 to date. We own exclusive, worldwide rights to these drug assets and related technologies, without royalty obligations to any third party. Our patent protection with respect to simufilam and use of simufilam for Alzheimer’s disease and other neurodegenerative disease currently runs beyond 2033 and includes over six issued patents and related patent filings and applications. In addition, we have patent protection with respect to simufilam for use in treating certain cancers that runs through 2034. We currently have no patents or patent applications in the United States with respect to SavaDx, which we believe is protected in the United States by trade secrets, know-how and other proprietary rights technology.

About Alzheimer’s Disease

Alzheimer’s disease is a progressive neurodegenerative disorder that affects cognition, function and behavior. More than 6 million Americans are estimated to have Alzheimer’s disease and it is predicted that number will increase to more than 13 million people by 2060, according to Alzheimers.gov, a government website managed by the NIH.

Phase 2a Study

In 2019, we completed a small, first-in-patient, clinical-proof-of-concept, open-label Phase 2a study of simufilam in the U.S., with substantial support from the National Institute on Aging (NIA), a division of the NIH. Treatment with simufilam for 28 days significantly improved certain key biomarkers of Alzheimer’s pathology, neurodegeneration and neuroinflammation (p<0.001). Biomarkers effects were seen in all patients in both cerebrospinal fluid (CSF) and plasma.

Phase 2b Study

In September 2020, we announced final results of a Phase 2b study with simufilam in Alzheimer’s disease. In this clinical study funded by the NIH, Alzheimer’s patients treated with 50 mg or 100 mg of simufilam twice-daily for 28 days showed statistically significant (p<0.05) improvements in CSF biomarkers of disease pathology, neurodegeneration and neuroinflammation, versus Alzheimer’s patients who took placebo. In addition, Alzheimer’s patients treated with simufilam showed improvements in validated tests of episodic memory and spatial working memory, versus patients on placebo. Cognitive improvements correlated most strongly with decreases in levels of P-tau181, a biomarker that suggests brain changes from Alzheimer’s disease.

Open-label Study Strategy

Much of the value of our ongoing open-label study is to gain data to support simufilam’s long-term safety profile in patients.

Clinical data from an open-label study has limitations compared to safety and efficacy data from a fully completed, large, randomized controlled clinical trial. However, we believe there is logic to conducting an open-label study prior to conducting a large, expensive Phase 3 clinical testing program. First, this is a standard clinical method of demonstrating drug safety. Second, we believe that if an experimental drug for Alzheimer’s shows no treatment benefits in a well-designed, long-term open-label study, then there is no chance that drug will succeed in Phase 3 clinical testing. The opposite is not true: encouraging treatment effects in an open-label study is not proof of drug safety or efficacy, nor can encouraging treatment effects predict clinical success in a Phase 3 program.

20

We believe a well-designed, long-term, open-label study is an exercise in prudent risk-management. Clinical results serve as a tool to help inform and manage the inherent risks and uncertainties of drug development for undertaking a large, expensive Phase 3 clinical testing program.

We also believe the use of interim analyses in our open-label study is a rational approach to inform the design of ongoing, pending, or future clinical studies. An interim analysis is a form of preliminary scientific enquiry that evaluates clinical data before a study is concluded, before patient enrollment has been completed and before data validation procedures are conducted to ensure the final clinical dataset is valid and accurate. Interim, “top-line” and preliminary data from our open-label clinical trial that we announce or publish from time to time are likely to change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final clinical dataset.

Open-label Study Results

In March 2020, we initiated a long-term, open-label study to evaluate simufilam, our lead drug candidate, in patients with Alzheimer’s disease. This study was funded in part by a research grant award from the National Institutes of Health (NIH). The study is intended to monitor the long-term safety and tolerability of simufilam 100 mg twice daily for 12 or more months. Another study objective is to measure changes in cognition and biomarkers. This study uses ADAS-Cog to measure changes in cognition and the Neuropsychiatric Inventory (NPI) to assess dementia-related behavior. Both scales are both standard clinical tools in trials of Alzheimer’s disease.

In September 2021, the open-label study reached its final target enrollment of approximately 200 subjects with mild-to-moderate Alzheimer’s disease. To date, simufilam appears safe and well-tolerated in this study.

Interim Analysis on 50 Patients at 6 Months. In February 2021, we announced top-line results of a preplanned interim analysis of our open-label study with simufilam. This interim analysis summarized clinical data in the first 50 patients who had completed at least 6 months of drug treatment. Patients’ cognition and behavior scores improved following six months of simufilam treatment, with no safety issues. Six months of simufilam treatment improved cognition scores by 1.6 points on ADAS-Cog11, a 10% mean improvement from baseline to month 6. In these same patients, simufilam also improved dementia-related behavior, such as anxiety, delusions and agitation, by 1.3 points on the Neuropsychiatric Inventory (NPI), a 29% mean improvement from baseline to month 6.

Interim Analysis on 50 Patients at 9 Months. In July 2021, we announced top-line results of a second preplanned interim analysis of our open-label study with simufilam. This interim analysis summarized clinical data on the first 50 patients who had completed at least 9 months of drug treatment. Patients’ cognition and behavior scores improved following nine months of simufilam treatment, with no safety issues. Nine months of simufilam treatment improved cognition scores by 3.0 points on ADAS-Cog11, an 18% mean improvement from baseline to month 9 (p<0.001). Simufilam improved ADAS-Cog scores in 66% of patients at 9 months. An additional 22% of patients declined less than reported in the science literature at 9 months. Cognition outcomes suggest simufilam’s treatment effects were broad-based (Figure 1).

Interim Analysis on 50 Patients at 12 Months. In September 2021, we announced top-line results of a third preplanned interim analysis of our open-label study with simufilam. This interim analysis summarized clinical data on the first 50 patients who had completed at least 12 months of drug treatment. Patients’ cognition and behavior scores both improved following twelve months of simufilam treatment, with no safety issues. Twelve months of simufilam treatment improved cognition scores by 3.2 points on ADAS-Cog11 from baseline to month 12 (p<0.001). Sixty-eight percent (68%) of study subjects improved on ADAS-Cog at 12 months; these study subjects improved an average of 6.8 points (S.D. ± 3.8). An additional 20% of study subjects declined less than 5 points on ADAS-Cog at 12 months; these study subjects declined an average of 2.5 points (S.D. ± 1.3).

Interim Analysis on 100 Patients at 12 Months. In August 2022, we announced results of an interim analysis that was conducted on the first 100 evaluable patients who completed at least 12 months of open-label treatment with simufilam 100 mg twice daily. Top-line results of this interim analysis show that from baseline to month-12:

Drug appears safe and well tolerated.

Overall ADAS-Cog11 scores improved an average of 1.5 points (S.D. ± 6.6; P<0.05)

21

63% of the 100 patients showed an improvement in ADAS-Cog11 scores, and this group of patients improved an average of 5.6 points (S.D. ± 3.8).

An additional 21% of the 100 patients declined less than 5 points on ADAS-Cog11, and this group of patients declined an average of 2.7 points (S.D. ± 1.4).

We expect to announce top-line data results of our open-label study approximately year-end 2022.

All clinical data from our open-label study are inherently exploratory in nature and, as with all open-label data, should be interpreted with caution. Data results from our open-label study does not constitute, and should not be interpreted as, evidence of therapeutic benefit for simufilam. Any interim data results should not be relied upon as indicative or predictive of full study results.

Figure 1. Individual Patient Changes in ADAS-Cog (N=50) at 9 months

Interim analyses summarize clinical data on the first 50 patients who have completed 6, 9, and 12 months of open-label treatment. Baseline values for cognition for each 50-patient cohort will not be the same at months 6, 9 and 12 because some study participants may drop out of the open-label study in-between interim analyses and dropouts are replaced, such that each interim analysis collects data from the first 50 patients who complete each specified time point.

22

Figure 2. Changes in ADAS-Cog (N=50) at 6, 9 and 12-month Interim Analyses

The 11-item Alzheimer’s Disease Assessment Scale–Cognitive subscale (ADAS-Cog) was originally developed by the research community to measure cognitive impairment in patients with Alzheimer’s disease. ADAS-Cog is often used in clinical studies of patients with Alzheimer’s because it can help determine incremental improvements or declines in cognition over time.

Standard deviation (“S.D.”) is a measure of how dispersed the data is in relation to the average. A low standard deviation generally shows the data are closely clustered around the average. A high standard deviation generally shows that the data is widely spread.

Historical Rates of Cognitive Decline - Alzheimer’s is a progressive disease. Cognition will always decline over time. Historical controls indicate that in patients with mild-to-moderate Alzheimer’s disease, cognition declines an average of 5.5 points on ADAS-Cog over 12 months amongst study subjects administered placebo in randomized, controlled trials, as reported by the science literature¹. As an example of decline in an early Alzheimer’s disease population, in 2020, one of our competitors, Biogen, Inc., reported a 5.2-point decline over 18 months on ADAS-Cog amongst study subjects who were administered placebo in two Phase 3 randomized, controlled trials studies with their proprietary drug, aducanumab².

Alzheimer’s is often accompanied by behavior disorders, such as anxiety, agitation or delusions. Such disorders may come and go over time, but they typically emerge or become more frequent as disease progresses. Simufilam reduced dementia-related behavior in the first 50 patients at 12 months of open-label treatment on the Neuropsychiatric Inventory (NPI), a clinical tool used to measure changes in dementia-related behavior.

At baseline, 34% of study subjects had no neuropsychiatric symptoms.

At month 6, 38% of study subjects had no neuropsychiatric symptoms.

At month 9, over 50% of study subjects had no neuropsychiatric symptoms.

At month 12, over 50% of study subjects had no neuropsychiatric symptoms.

Biomarker Analysis. Biomarkers are objective biological data. There are no known placebo effects. A key objective of this study is to measure changes in levels of biomarkers in patients before and after 6 months and 12 months of open-label treatment with simufilam.

In July 2021, we announced positive biomarker data from our open-label study. Six months of open label treatment with simufilam robustly improved CSF biomarkers in a cohort of 25 patients with mild-to-moderate Alzheimer’s disease. Biomarker data were analyzed from cerebrospinal fluid (CSF) collected from 25 study participants in the open-label study who agreed to undergo a lumbar puncture at baseline and again after 6 months of treatment. CSF bioanalyses were conducted blind by City University of New York (CUNY).

Cerebrospinal fluid (CSF) biomarkers of disease pathology, t-tau and p-tau181, decreased 38% and 18%, respectively (both p<0.00001). CSF biomarkers of neurodegeneration, neurogranin and Nfl, decreased 72% and 55%, respectively (both p<0.00001). CSF biomarkers of neuroinflammation, sTREM2 and YKL-40, decreased 65% and 44% (both p<0.00001). All p-values are baseline vs. 6-month levels by paired t-test. Figure 3.

Core markers of Alzheimer’s pathology are total tau (T-tau), phosphorylated tau (P-tau181), and amyloid beta42 (Aβ₄₂). In Alzheimer’s, tau levels are elevated and Aβ₄₂ is low.

T-tau decreased 38% (p<0.00001)

P-tau181 decreased 18% (p<0.00001)

CSF Aβ₄₂ increased 84% (p<0.00001)
‎

Elevated CSF levels of two proteins, neurogranin (Ng) and neurofilament Light Chain (NfL) indicate neurodegeneration.

Ng decreased 72% (p<0.00001)

NfL decreased 55% (p<0.00001)
‎

Elevated levels of marker YKL-40 indicate neuroinflammation.

YKL-40 decreased 44% (p<0.00001)
‎

sTREM2 is a biomarker of microglia-induced neuroinflammation that has commanded substantial recent attention from researchers for its role in Alzheimer’s and frontotemporal dementia.

sTREM2 decreased 65% (p<0.00001)

HMGB1 protein, is a damage-related protein sometimes called a ‘danger molecule’ because it triggers additional neuroinflammation and loss of neurons.

HMGB1 decreased 53% (p<0.00001)

Cognition Maintenance Study (CMS)

In May 2021, we initiated a Cognition Maintenance Study (CMS). This is a double-blind, randomized, placebo-controlled study of simufilam in patients with mild-to-moderate Alzheimer’s disease. Study subjects are randomized (1:1) to simufilam or placebo for six months. To enroll in the CMS, patients must have previously completed 12 months or more of open-label treatment with simufilam. The CMS is designed to evaluate simufilam’s effects on cognition and health outcomes in Alzheimer’s patients who continue with drug treatment versus patients who discontinue drug treatment. Figure 4.

The target enrollment for the CMS is approximately 100 patients or more. As of November 2, 2022, over 65 patients have completed this study. Our goal is to complete patient enrollment for the CMS in Q4 2022 and announce clinical results approximately third-quarter 2023.

End-of-Phase 2 (EOP2) Meeting with FDA

In January 2021, we held an End-of-phase 2 (EOP2) meeting for simufilam with the U.S. Food and Drug Administration (FDA). The purpose of this EOP2 meeting was to gain general agreement around key elements of a pivotal Phase 3 program to treat Alzheimer’s disease dementia. FDA attendees included Robert Temple, MD, Deputy Center Director for Clinical Science and Senior Advisor in the Office of New Drugs; Billy Dunn, MD, Director, Office of Neuroscience; Eric Bastings, MD, Director, Division of Neurology, and others.

25

In February 2021, we announced the successful completion of our EOP2 meeting. Official meeting minutes confirm that we and FDA are aligned on key elements of a Phase 3 clinical program for simufilam. FDA has agreed that the completed Phase 2 program, together with an ongoing and well-defined Phase 3 clinical program, are sufficient to show evidence of clinical efficacy for simufilam in Alzheimer’s disease. There is also agreement that the use of separate clinical scales to assess cognition (ADAS-cog¹) and function (ADCS-ADL²) are appropriate co-primary endpoints of efficacy. A clinical scale that combines cognition and function, such as iADRS³, is a secondary efficacy endpoint.

Special Protocol Assessments

In August 2021, we announced we had reached agreement with FDA under a Special Protocol Assessment (SPA) for both Phase 3 studies. These SPA agreements document that FDA has reviewed and agreed upon the key design features of our Phase 3 study protocols of simufilam for the treatment of patients with Alzheimer’s disease.

An SPA agreement indicates concurrence by the FDA with the adequacy and acceptability of specific critical elements of overall protocol design (e.g., entry criteria, dose selection, endpoints, etc.). These elements are critical to ensure that our planned Phase 3 studies of simufilam in Alzheimer’s disease can be considered adequate and well-controlled studies in support of a future regulatory submission and marketing application.

The first clinical study protocol under the SPA is titled “A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, 52-Week Study Evaluating the Safety and Efficacy of One Dose of Simufilam in Subjects with Mild-to-Moderate Alzheimer's Disease.”

The second clinical study protocol under the SPA is titled “A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, 76-Week Study Evaluating the Safety and Efficacy of Two Doses of Simufilam in Subjects with Mild-to-Moderate Alzheimer’s Disease.”

Phase 3 Drug Supply

In March 2021, we announced we had entered into a drug supply agreement with Evonik Industries AG for simufilam. Under the agreement, Evonik will supply us with large-scale, clinical-grade quantities of simufilam. Evonik is one of the world’s largest contract development and manufacturing organizations for pharmaceutical ingredients. Other vendors supply excipients, the finished dosage form (i.e., simufilam tablets), drug packaging, package labeling and other critical steps in the supply chain for Phase 3 drug supply.

Phase 3 Clinical Program Overview

The Phase 3 program consists of two large, double-blind, randomized, placebo-controlled studies of simufilam in patients with mild-to-moderate Alzheimer’s disease dementia. Figure 5. In 2021, the FDA granted each study a Special Protocol Assessment (SPA). In June 2021, we announced the selection of Premier Research International as our CRO to help conduct the Phase 3 clinical program of simufilam for Alzheimer’s disease.

Figure 5.

RETHINK-ALZ and REFOCUS-ALZ

In October and November 2021, we announced initiation of our two Phase 3 studies of simufilam, respectively. As of November 2, 2022, a total of over 650 subjects have been enrolled in the Phase 3 program. Patients are now being screened in clinical trial sites in the U.S., Canada, Puerto Rico, Australia, and South Korea.

The first Phase 3 study, called RETHINK-ALZ, is designed to evaluate the safety and efficacy of oral simufilam 100 mg in enhancing cognition and slowing cognitive and functional decline over 52 weeks. Secondary objectives include the assessment of simufilam's effect on neuropsychiatric symptoms and caregiver burden. This randomized, double-blind, placebo-controlled study plans to enroll approximately 750 patients with mild-to-moderate Alzheimer’s disease.

27

Details of the RETHINK-ALZ Phase 3 study include:

Approximately 750 subjects with mild-to-moderate Alzheimer’s disease to be enrolled.

Subjects to be randomized (1:1) to simufilam 100 mg or placebo twice daily.

Subjects to be treated for 12 months.

The co-primary efficacy endpoints are ADAS-Cog¹, a cognitive scale, and ADCS-ADL², a functional scale; both are standard clinical tools in trials of Alzheimer’s disease.

A secondary efficacy endpoint is iADRS³, a standard clinical tool in trials of Alzheimer’s disease that combines cognitive and functional scores from ADAS-Cog & ADCS-ADL.

Other secondary endpoints include plasma biomarkers of disease and NPI⁴, a clinical tool that assesses the presence and severity of dementia-related behavior.

In November 2021, we announced initiation of a second Phase 3 study, called REFOCUS-ALZ, designed to evaluate the safety and efficacy of oral simufilam 100 mg and 50 mg over 76 weeks. This randomized, double-blind, placebo-controlled study plans to enroll approximately 1,000 patients with mild-to-moderate Alzheimer’s disease.

Details of the REFOCUS-ALZ Phase 3 study include:

Approximately 1,000 subjects with mild-to-moderate Alzheimer’s disease to be enrolled.

Subjects to be randomized (1:1:1) to simufilam 100 mg, 50 mg, or placebo BID.

Subjects to be treated for 76 weeks.

The co-primary efficacy endpoints are ADAS-Cog¹, a cognitive scale, and ADCS-ADL², a functional scale; both are widely used clinical tools in trials of Alzheimer’s disease.

A secondary efficacy endpoint is iADRS³, a widely used clinical tool in trials of Alzheimer’s disease that combines cognitive and functional scores from ADAS-Cog & ADCS-ADL.

Other secondary endpoints include CSF, plasma and imaging biomarkers of disease and NPI⁴, a clinical tool that assesses the presence and severity of dementia-related behavior.

Open-label Extension Study for the Phase 3 Program

In October 2022, we announced the initiation of an open-label extension study for our Phase 3 program. This new study is designed to provide no-cost access to simufilam to patients with Alzheimer’s disease who have successfully completed a Phase 3 study of simufilam.

This multi-center, multi-national, open-label extension study is expected to generate long-term safety and tolerability data for (oral) simufilam 100 mg twice daily over 52 weeks. Each clinical investigational site must choose whether to participate in this open-label extension study. Patient enrollment for this study is expected to begin early November 2022.

SavaDx

Our investigational product candidate, called SavaDx, is early-stage program focused on detecting the presence of Alzheimer’s disease from a small sample of blood. For business, technical and personnel reasons, we continue to prioritize the development of simufilam, our novel drug candidate, over SavaDx, our novel diagnostic candidate.

The regulatory pathway for SavaDx may eventually include formal analytical validation studies and clinical studies that support evidence of sensitivity, specificity and other variables in various healthy and diseased patient populations. We have not conducted such studies and do not expect to conduct such studies in 2022.

SavaDx is currently designed as an antibody-based detection system for altered filamin A (FLNA). Working with third parties, we continue to evaluate an innovative method to detect FLNA without the use of antibodies.

Impact of COVID-19 on our Business

During the COVID-19 pandemic, our top priorities are to protect the health, well-being, and safety of our employees and partners, while still focusing on the key drivers of our business. Despite COVID-19, we believe we are on-track to achieve our major strategic objectives for 2022 with simufilam. We have generally not experienced major disruptions across our drug manufacturing operations or supply of materials. We believe certain investigational clinical study sites that are involved, or potentially would like to be involved, with our clinical programs may be experiencing lingering, pandemic-related after-effects, such as staffing shortages, operational gaps or other adverse circumstances. Our broad spectrum of technical consultants, scientific advisors and service providers continue to provide timely services. We have adapted flexible business practices, such as remote work arrangements and temporary travel restrictions, to insure we continue to operate safety and cautiously while also meeting our public health responsibilities. We recognize the pandemic has created a dynamic and uncertain situation in the national economy. We continue to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on our operations. However, the scope of pandemic is unprecedented and its long-term impact on our operations and financial condition cannot be reasonably estimated at this time.

Financial Overview

We have yet to generate any revenues from product sales. We have an accumulated deficit of $264.4 million at September 30, 2022. These losses have resulted principally from costs incurred in connection with research and development activities, salaries and other personnel-related costs and general corporate expenses. Research and development activities include costs of preclinical and clinical trials as well as clinical supplies associated with our product candidates. Salaries and other personnel-related costs include stock-based compensation associated with stock options and other equity awards granted to employees and non-employees. Our operating results may fluctuate substantially from period to period as a result of the timing of preclinical activities, enrollment rates of clinical trials for our product candidates and our need for clinical supplies.

We expect to continue to use significant cash resources in our operations for the next several years. Our cash requirements for operating activities and capital expenditures may remain substantial in the future as we:

continue our ongoing Phase 3 program with simufilam;

manufacture large-scale supplies for simufilam;

conduct other preclinical and clinical studies for our product candidates;

29

seek regulatory approvals for our product candidates;

develop, formulate, manufacture and commercialize our product candidates;

implement additional internal systems and develop new infrastructure;

acquire or in-license additional products or technologies, or expand the use of our technology;

maintain, defend and expand the scope of our intellectual property; and

hire additional personnel.

Product revenue will depend on our ability to receive regulatory approvals for, and successfully market, our product candidates. If our development efforts result in regulatory approval and successful commercialization of our product candidates, we expect to generate revenue from direct sales of our drugs and/or, if we license our drugs to future collaborators, from the receipt of license fees and royalties from sales of licensed products. We conduct our research and development programs through a combination of internal and collaborative programs. We rely on arrangements with universities, certain collaborators, contract development and manufacturing organizations (CDMOs), CROs and clinical research sites for a significant portion of our product development efforts.

We focus substantially all of our research and development efforts in the area of neurology. The following table summarizes expenses by category for research and development efforts (in thousands):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Compensation	$	1,765	$	1,306	$	5,512	$	3,177
Contractor fees and supplies		16,478		6,444		44,154		10,748
Other common costs		283		291		714		546
	$	18,526	$	8,041	$	50,380	$	14,471

Research and development expenses include compensation, contractor fees and supplies as well as allocated common costs. Contractor fees and supplies generally include expenses for clinical studies and preclinical studies and costs for formulation and manufacturing activities. Other common costs include the allocation of common costs such as facilities. During the three months ended September 30, 2022 and 2021, we received $0.4 million and $2.0 million in NIH research grants, respectively. During the nine months ended September 30, 2022 and 2021, we received $0.9 million and $3.5 million from NIH research grants, respectively. These reimbursements were recorded as a reduction to our research and development expenses.

Our technology has been applied across certain of our product candidates. Data, know-how, personnel, clinical results, research results and other matters related to the research and development of any one of our product candidates also relate to, and further the development of, our other product candidates. As a result, costs allocated to a specific drug candidate may not necessarily reflect the actual costs surrounding research and development of that product candidate due to cross application of the foregoing.

Estimating the dates of completion of clinical development, and the costs to complete development, of our product candidates would be highly speculative, subjective and potentially misleading. Pharmaceutical product candidates take a significant amount of time to research, develop and commercialize. The clinical trial portion of the development of a new drug alone usually spans several years. We expect to reassess our future research and development plans based on our review of data we receive from our current research and development activities. The cost and pace of our future research and development activities are linked and subject to change.

Critical Accounting Estimates

This discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported expenses and net loss incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under

30

the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting estimates during the nine months ended September 30, 2022 from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 1, 2022.

Results of Operations – Three and Nine Months Ended September 30, 2022 and 2021

Research and Development Expense

Research and development expenses consist primarily of costs of drug development work associated with our product candidates, including:

clinical trials,

pre-clinical testing,

clinical supplies and related formulation and design costs, and

compensation and other personnel-related expenses.

Research and development expenses were $18.5 million and $8.0 million during the three months ended September 30, 2022 and 2021, respectively. This significant increase was due primarily to costs to conduct the ongoing Phase 3 clinical program in simufilam and costs of an on-going cognition maintenance study and open-label study in simufilam compared to the prior year. Higher pre-clinical study costs as well as increased personnel costs also contributed to the increase. Grant funding received from NIH, recorded as a reduction in research and development expenses, also decreased compared to the prior year. During the three months ended September 30, 2022 and 2021, we received $0.4 million and $2.0 million in research grants from NIH, respectively.

Research and development expenses were $50.4 million and $14.5 million during the nine months ended September 30, 2022 and 2021, respectively. This significant increase was due primarily to costs to conduct the ongoing Phase 3 clinical program in simufilam, costs of an on-going cognition maintenance study and open-label study in simufilam, and costs related to manufacture of clinical trial supplies compared to the prior year. Higher pre-clinical study costs as well as increased personnel costs also contributed to the increase. Grant funding received from NIH, recorded as a reduction in research and development expenses, also decreased compared to the prior year. During the nine months ended September 30, 2022 and 2021, we received $0.9 million and $3.5 million in research grants from NIH, respectively.

We expect research and development expense to continue at historically high levels as we conduct a Phase 3 clinical program and other clinical studies with simufilam, continue to hire new personnel, manufacture drug supply, and continue our development efforts.

General and Administrative Expense

General and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including legal, human resources, audit and accounting services. Personnel costs consist of salaries, bonus, benefits and stock-based compensation. Allocated expenses consist primarily of leased facility costs. Depreciation and amortization for office space leased but not occupied by the Company is included in general and administrative expense. Depreciation and amortization for office space occupied by the Company is allocated between general and administrative expense and research and development expense. We also incur expenses associated with operating as a public company, including additional legal fees, expenses related to compliance with the rules and regulations of the SEC and Nasdaq, additional insurance and audit expenses, investor relations activities, Sarbanes-Oxley compliance expenses and other administrative expenses and professional services.

General and administrative expenses were $2.8 million and $1.7 million during the three months ended September 30, 2022 and 2021, respectively. The 65% increase was due primarily to $0.7 million in higher legal expenses as well

31

as a $0.2 million increase in depreciation and amortization for the two-building office complex in Austin, Texas, purchased in August 2021, as compared to the prior year.

General and administrative expenses were $8.7 million and $4.0 million during the nine months ended September 30, 2022 and 2021, respectively. The 120% increase was due primarily to $3.1 million in higher legal expenses as well as $0.8 million increase in depreciation and amortization for our office complex in Austin, Texas, purchased in August 2021 as compared to the prior year.

We expect our general and administrative expenses to continue at historically high levels in future periods due primarily to anticipated higher legal and professional fees related to ongoing lawsuits and governmental investigations.

Interest Income

Interest income was $0.9 million and $15,000 during the three months ended September 30, 2022 and 2021, respectively.

Interest income was $1.2 million and $35,000 during the nine months ended September 30, 2022 and 2021, respectively.

The increase in interest income was due to increases in interest rates in 2022 compared to the prior periods.

We expect interest income to increase in 2022 compared to 2021 due to the increases in interest rates.

Other income, net

We record the activities related to leasing office space to third parties in buildings we own as other income, net, as leasing is not core to the Company’s operations. Other income, net, was $210,000 and 176,000 during the three months ended September 30, 2022 and 2021, respectively. Other income, net, was $748,000 and $176,000 during the nine months ended September 30, 2022 and 2021, respectively. Other income, net, was higher in 2022 as we acquired the two-building office complex in August 2021.

Depreciation and amortization for the office complex is included in general and administrative and research and development expense, and thus not reflected in other income, net.

Liquidity and Capital Resources

Since inception, we have financed our operations primarily through public and private stock offerings, payments received under collaboration agreements and interest earned on our cash and cash equivalents balances. We intend to continue to use our capital resources to fund research and development activities, capital expenditures, working capital requirements and other general corporate purposes. As of September 30, 2022, cash and cash equivalents were $174.7 million.

2021 Registered Direct Offering

On February 12, 2021, we completed a common stock offering pursuant to which certain investors purchased 4,081,633 shares of common stock at a price of $49.00 per share. Net proceeds of the offering were approximately $189.8 million after deducting offering expenses.

Common Stock Warrants

In August 2018, we issued warrants to purchase up to an aggregate of 9.1 million shares of common stock in conjunction with an offering of our common stock.

We did not receive any proceeds from exercise of common stock warrants during the three or nine months ended September 30, 2022. We did not receive any proceeds from exercise of common stock warrants during the three months ended September 30, 2021. During the nine months ended September 30, 2021, we received proceeds of $0.7 million from the exercise of 0.6 million shares pursuant to warrants.

32

There were no common stock warrants outstanding as of September 30, 2022.

At-the-Market Common Stock Offering

In March 2020, we established an at-the-market offering program (“ATM”) to sell, from time to time, shares of our common stock having an aggregate offering price of up to $100 million in transactions pursuant to a shelf registration statement that was declared effective by the SEC on May 5, 2020. We are obligated to pay a commission of 3.0% of the gross proceeds from the sale of shares of common stock in the offering. We are not obligated to sell any shares in the offering.

There were no common stock sales under the ATM during the three or nine months ended September 30, 2022 and 2021.

NIH Research Grant Awards

Our programs have been supported by NIH under multiple research grant awards. Strong, long-term support from NIH has allowed us to advance our two lead product candidates, simufilam and SavaDx, into clinical development.

In May 2021, we were awarded a research grant award from NIH of up to $2.7 million to support clinical readiness activities in support of our Phase 3 program with simufilam. All of our NIH research grant awards are paid out on a reimbursement basis and require milestone-based technical progress. There were no remaining funds for grant awards as of September 30, 2022.

2020 Cash Incentive Bonus Plan Obligations

In August 2020, the Board approved the 2020 Cash Incentive Bonus Plan (the Plan). The Plan was established to promote the long-term success of the Company by creating an “at-risk” cash bonus program that rewards Plan participants with additional cash compensation in lockstep with significant increases in the Company’s market capitalization. The Plan is considered “at-risk” because Plan participants will not receive a cash bonus unless the Company’s market capitalization increases significantly and certain other conditions specified in the Plan are met. Specifically, Plan participants will not be paid any cash bonuses unless (1) the Company completes a merger or acquisition transaction that constitutes a sale of ownership of the Company or its assets (a Merger Transaction) or (2) the Compensation Committee determines the Company has sufficient cash on hand, as defined in the Plan. Plan participants will be paid all earned cash bonuses in the event of a Merger Transaction.

The Company’s market capitalization, including all outstanding stock options, was $89.4 million at the inception of the Plan in August 2020. If the Company were to exceed a $5 billion market capitalization for no less than 20 consecutive trading days, and conditions noted above for payment are met, all Plan milestones would be deemed achieved, in which case total cash bonus awards would range from a minimum of $139.1 million up to a hypothetical maximum of $322.3 million.

The Company’s potential financial obligation to plan participants at September 30, 2022 totaled $7.3 million, based upon the achievement of one Plan milestone in the Company’s market capitalization in 2020. No actual cash bonus payments have been made to any Plan participant, as the Company has not yet satisfied all the conditions necessary for amounts to be paid under the Plan. During the year ended December 31, 2021, the Company’s market capitalization increased substantially. These increases triggered the achievement of 11 additional Plan milestones. Collectively, the achievement of such milestones could trigger potential Company obligations to Plan participants ranging from a minimum of $93.7 million up to a hypothetical maximum of $225.0 million, with exact amounts to be determined by the Compensation Committee and contingent upon future satisfaction of a Performance Condition.

No Valuation Milestones were achieved during the three and nine months ended September 30, 2022.

No actual cash payments were authorized or made to participants under the Plan as of September 30, 2022, or through the filing date of this Form 10-Q.

Use of Cash

Net cash used in operating activities was $56.2 million for the nine months ended September 30, 2022, resulting primarily from the net loss reported of $57.1 million, a decrease in accounts payable of $3.6 million and accrued compensation and benefits of $1.7 million, partially offset by a decrease in in prepaid and other assets of $2.8 million, an increase in accrued developmental expenses of $1.3 million and stock-based compensation expense of $1.5 million.

Net cash used in operating activities was $22.2 million for the nine months ended September 30, 2021, resulting primarily from the net loss reported of $18.2 million and an increase in prepaid and other assets of $10.1 million, partially offset by an increase in accrued development expense of $2.5 million, accounts payable of $1.4 million, other current liabilities of $0.6 million and stock-based compensation expense of $1.2 million.

Net cash used in investing activities during the nine months ended September 30, 2022 was $3.0 million related to renovations and fixtures for our corporate headquarters.

Net cash used in investing activities during the nine months ended September 30, 2021 was $22.1 million related to the purchase of an office complex in Austin, Texas, a portion of which serves as our corporate headquarters.

Net cash provided by financing activities during the nine months ended September 30, 2022 was $0.5 million, from the exercise of stock options.

Net cash provided by financing activities during the nine months ended September 30, 2021 was $192.3 million, consisting of $189.8 million in proceeds from our registered direct offering of common stock in February 2021, $1.8 million from the exercise of stock options and $0.7 million in proceeds from the exercise of common stock warrants.

Property and Leases

In August 2021, we completed the purchase of an office complex in Austin, Texas, a portion of which serves as our corporate headquarters. This property is intended to accommodate our anticipated growth and expansion of our operations in the coming years. Maintenance, physical facilities, leasing, property management and other key responsibilities related to property ownership are outsourced to professional real-estate managers. The purchase price of the property was $22.0 million, including closing costs, funded with cash on hand. The office complex measures approximately 90,000 rentable square feet. The property is currently over 60% leased. We occupied approximately 25% of the property beginning late August 2022.

We lease approximately 6,000 square feet of office space pursuant to a non-cancelable operating lease in Austin, Texas that expires in April 2024. We also leased an additional 3,600 square feet of office space in Austin, Texas that expired on October 31, 2022.

Other Commitments

We have an accumulated deficit of $264.4 million as of September 30, 2022. We expect our cash requirements to be significant in the future. The amount and timing of our future cash requirements will depend on regulatory and market acceptance of our drug candidates, the resources we devote to researching and developing, formulating, manufacturing, commercializing and supporting our products and other corporate needs. We believe that our current cash and cash equivalents will be sufficient to fund our operations for at least the next 12 months. We may seek additional future funding through public or private financing in the future, if such funding is available and on terms acceptable to us. However, there are no assurances that additional financing will be available on favorable terms, or at all.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business, primarily related to interest rate sensitivities and, to a lesser extent, currency fluctuations related to our clinical operations outside the U.S.

Interest Rate Sensitivity

We are exposed to market risk related to changes in interest rates. We had cash, cash equivalents and marketable securities of $174.7 million as of September 30, 2022, which consisted primarily of U.S. Treasury securities and money market accounts.

The primary objective of our investment activities is to preserve capital to fund our operations. We also seek to maximize income from our investments without assuming significant risk. To achieve our objectives, we maintain investment vehicles with high credit quality and short-term duration, in accordance with our board-approved investment policy. Such interest-earning instruments carry a degree of interest rate risk. However, due to the generally short-term maturities and low risk profile of our cash equivalents, an immediate 100 basis point increase or decrease in interest rates during any of the periods presented would increase or decrease our annual net loss by less than $2 million in our condensed consolidated financial statements.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures. Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer (as Principal Executive Officer) and our Chief Financial Officer (as Principal Financial Officer) have concluded that our disclosure controls and procedures are effective to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2022, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal control over financial reporting. There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified during the three months ended September 30, 2022 that has materially affected, or is reasonable likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may become involved in litigation or other legal proceedings and claims, including U.S. government inquiries and investigations. The outcome of these proceedings is inherently uncertain. Regardless of outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors. At this time, no assessment can be made as to their likely outcome or whether the outcome will be material to us. No information is available to indicate that it is probable that a loss has been incurred or can be reasonably estimated as of the date of the consolidated financial statements and, as such, no accrual for these matters has been recorded within the consolidated financial statements.

35

Government Investigations

On November 15, 2021, we disclosed that certain government agencies had asked us to provide them with corporate information and documents. These were confidential requests. We have been voluntarily cooperating and will continue to cooperate with government authorities. No government agency has informed us that it has found evidence of research misconduct. No government agency has informed us that any wrongdoing has occurred by any party. No government agency has filed any charges against us, or anyone associated with us. We cannot predict the outcome or impact of any these ongoing matters, including whether a government agency may pursue an enforcement action against us or others.

Securities Class Actions and Shareholder Derivative Actions

Between August 27, 2021 and October 26, 2021, four putative class action lawsuits were filed alleging violations of the federal securities laws by us and certain named officers. The complaints rely on allegations contained in Citizen Petitions that were submitted to FDA, and allege that various statements made by the defendants regarding simufilam were rendered materially false and misleading. The Citizen Petitions were all subsequently denied by FDA. These actions were filed in the U.S. District Court for the Western District of Texas. The complaints seek unspecified compensatory damages and other relief on behalf of a purported class of purchasers of our securities. On June 30, 2022, a federal judge consolidated the four class action lawsuits into one case and appointed a lead plaintiff and a lead counsel. Lead plaintiff filed a consolidated amended complaint on August 18, 2022 on behalf of a putative class of purchasers of our securities between September 14, 2020 and July 26, 2022. Briefing on defendants’ motion to dismiss is scheduled to be completed by January 23, 2023. We believe the claims are without merit and intend to defend against these lawsuits vigorously. We are unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

On November 4, 2021, a related shareholder derivative action was filed, purportedly on behalf of the Company, in the U.S. District Court for the Western District of Texas, asserting claims under the U.S. securities laws and state fiduciary duty laws against certain named officers and the members of the Company’s board of directors. This complaint relies on allegations made in Citizen Petitions that were submitted to (and subsequently denied by) FDA. The complaint alleges, among other things, that the individual defendants exposed the Company to unspecified damages and securities law liability by causing it to make materially false and misleading statements, in violation of the U.S. securities laws and in breach of their fiduciary duties to the Company. The derivative case seeks, among other things, to recover unspecified compensatory damages on behalf of the Company arising out of the individual defendant’s alleged wrongful conduct. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants. Since November 4, 2021, three additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, and one in Texas state court (Travis County District Court). All four actions have been stayed pending the resolution of the motions to dismiss in the securities class actions. On July 5, 2022, the three federal court actions were consolidated into a single action.

On August 19, 2022, a shareholder derivative action was filed, purportedly on behalf of the Company, in the Delaware Court of Chancery, asserting claims under state fiduciary duty laws against certain named officers and members of the Company’s board of directors. The complaint alleges, among other things, that the individual defendants breached their fiduciary duties by approving the 2020 Cash Incentive Bonus Plan in August 2020. The complaints seek unspecified compensatory damages and other relief. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants.

We are unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

Item 1A. Risk Factors

There have been no material changes to our risk factors from those disclosed under “Risk Factors” in Part I, Item 1A of our 2021 Annual Report on Form 10-K. The risks and uncertainties described in our 2021 Annual Report on Form 10-K are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business, financial condition or results of operations.

General And Liquidity [Abstract]

General And Liquidity

Note 1. General and Liquidity

Cassava Sciences, Inc. and its wholly-owned subsidiary (collectively referred to as the “Company”) discover and develop proprietary pharmaceutical product candidates that may offer significant improvements to patients and healthcare professionals. The Company generally focuses its discovery and product development efforts on disorders of the nervous system.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. All intercompany transactions and balances have been eliminated in consolidation. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management of the Company, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year 2022. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Coronavirus Disease 2019 (COVID-19)

The widespread outbreak of a novel infectious disease called Coronavirus Disease 2019, or COVID-19, and the impact of the omicron and other variants and subvariants of this disease, has not significantly impacted the Company’s operations or financial condition as of November 7, 2022. We believe certain investigational clinical study sites that are involved, or potentially would like to be involved, with our clinical programs may be experiencing lingering, pandemic-related after-effects, such as staffing shortages, operational gaps or other adverse circumstances. Also, this pandemic has created a dynamic and uncertain situation in the national economy. The Company continues to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on its operations and financial condition. The scope of pandemic is unprecedented, and its long-term impact on the Company’s operations and financial condition cannot be reasonably estimated at this time.

Liquidity

The Company has incurred significant net losses and negative cash flows since inception, and as a result has an accumulated deficit of $264.4 million at September 30, 2022. The Company expects its cash requirements to be significant in the future. The amount and timing of the Company’s future cash requirements will depend on regulatory and market acceptance of its product candidates and the resources it devotes to researching and developing, formulating, manufacturing, commercializing and supporting its products. The Company may seek additional funding through public or private financing in the future, if such funding is available and on terms acceptable to the Company. There are no assurances that additional financing will be available on favorable terms, or at all. However, management believes that the current working capital position will be sufficient to meet the Company’s working capital needs for at least the next 12 months.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

Note 2.  Significant Accounting Policies

Use of Estimates

The Company makes estimates and assumptions in preparing its condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to manufacturing agreements and research collaborations. Actual results could differ from these estimates and assumptions.

Cash and Cash Equivalents and Concentration of Credit Risk

The Company invests in cash and cash equivalents. The Company considers highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered cash equivalents include money market accounts and funds, certificates of deposit, and U.S. Treasury securities. The Company maintains its cash and cash equivalents at one financial institution.

Fair Value Measurements

The Company recognizes financial instruments in accordance with the authoritative guidance on fair value measurements and disclosures for financial assets and liabilities. This guidance defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. The guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

Level 1 includes quoted prices in active markets.

Level 2 includes significant observable inputs, such as quoted prices for identical or similar securities, or other inputs that are observable and can be corroborated by observable market data for similar securities. The Company uses market pricing and other observable market inputs obtained from third-party providers. It uses the bid price to establish fair value where a bid price is available. The Company does not have any financial instruments where the fair value is based on Level 2 inputs.

Level 3 includes unobservable inputs that are supported by little or no market activity. The Company does not have any financial instruments where the fair value is based on Level 3 inputs.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The fair value of cash and cash equivalents was based on Level 1 inputs at September 30, 2022 and December 31, 2021.

Business Segments

The Company reports segment information based on how it internally evaluates the operating performance of its business units, or segments. The Company’s operations are confined to one business segment: the development of novel drugs and diagnostics.

Proceeds from Grants

During the three months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.4 million and $2.0 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the nine months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.9 million and $3.5 million pursuant to NIH research grants, respectively. The Company records the proceeds from these grants as reductions to its research and development expenses.

Stock-based Compensation 

The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. This model requires the input of subjective assumptions including expected stock price volatility, expected life and estimated forfeitures of each award. These assumptions consist of estimates of future market conditions, which are inherently uncertain, and therefore, are subject to management's judgment. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years.

The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit

service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria.

Net Loss per Share

The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options.  There is no difference between the Company’s net loss and comprehensive loss. The numerators and denominators in the calculation of basic and diluted net loss per share were as follows (in thousands, except net loss per share data):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Numerator:
Net loss	$	(20,257)	$	(9,562)	$	(57,112)	$	(18,213)
Denominator:
Shares used in computing net loss per share, basic and diluted		40,050		39,957		40,009		39,218
Net loss per share, basic and diluted	$	(0.51)	$	(0.24)	$	(1.43)	$	(0.46)
Dilutive common stock options excluded from net loss per share, diluted		1,946		2,350		2,064		2,219

The Company excluded common stock options outstanding, along with 57,143 restricted stock awards, from the calculation of net loss per share, diluted, because the effect of including outstanding options and warrants would have been anti-dilutive. The 57,143 restricted stock awards expired during the nine months ended September 30, 2022.

Fair Value of Financial Instruments   

Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments.

Research Contract Costs and Accruals

The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable. Related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs.

Incentive Bonus Plan

In 2020, the Company established the 2020 Cash Incentive Bonus Plan (the “Plan”) to incentivize Plan participants. Awards under the Plan are accounted for as liability awards under Accounting Standards Codification (ASC) 718 “Stock-based Compensation”. The fair value of each potential Plan award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each Plan award, when a Performance Condition (as defined below) is considered probable of being met. See Note 10 for further discussion of the Plan.

Leases

The Company recognizes assets and liabilities that arise from leases. For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments during the lease term, in the condensed consolidated balance sheets. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities. As the Company`s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Property and equipment

Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Owned buildings and related improvements have estimated useful lives of 39 years and approximately 10 years, respectively. Tenant improvements related to leased space are amortized using the straight-line method over the useful lives of the improvements or the remaining term of the corresponding leases, whichever is shorter. The remaining term of the corresponding leases is approximately 1.6 years.

Property and equipment are reviewed for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If property and equipment are considered to be impaired, an impairment loss is recognized.

Intangible assets

Acquired intangible assets are recorded at fair value at the date of acquisition and primarily consist of lease-in-place agreements and leasing commissions. Intangible assets are amortized over the estimated life of the lease-in-place agreements, which is approximately 1.5 years at September 30, 2022.

Intangible assets are reviewed for impairment on an annual basis, and when there is reason to believe that their values have been diminished or impaired. If intangible assets are considered to be impaired, an impairment loss is recognized.

Income Taxes 

The Company accounts for income taxes under the asset and liability method.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance.

The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s condensed consolidated financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.

Real Property Acquisition

Note 4. Real Property Acquisition

On August 4, 2021, the Company completed the all-cash purchase of a two-building office complex in Austin, Texas, a portion of which serves as its corporate headquarters. This property is intended to accommodate the Company’s anticipated growth and expansion of its operations in the coming years. Maintenance, physical facilities, leasing, property management and other key responsibilities related to property ownership are being outsourced to professional real-estate managers. The purchase price of the property was $22.0 million, including transaction costs. The office complex measures approximately 90,000 rentable square feet. At September 30, 2022, the property was over 60% leased. The Company also occupies approximately 25% of the property. The seller was a third party not affiliated with the Company.

The purchase was accounted for as an asset acquisition under ASC 805, Business Combinations. As substantially all of the fair value of the gross assets acquired were concentrated into a single identifiable asset, the Company concluded that the screen was met, and the transaction is considered an asset acquisition rather than an acquisition of a business. Pursuant to the cost accumulation method as prescribed in ASC 805, the cost of the acquisition, including certain transaction costs, is allocated to the assets acquired on the basis of relative fair values. The value of acquired in-place leases was measured as the sum of lost revenues that would be incurred during a prospective lease-up period that would be necessary to achieve occupancy similar to that at the time of acquisition. The value was calculated as the average number of months of lease-up multiplied by the gross monthly market rental rate (base rent plus reimbursements) for each particular suite.

The assets acquired are summarized as follows (in thousands):

Land	$	3,734
Buildings		15,980
Site improvements		453
Tenant improvements		567
Total tangible assets	$	20,734
Lease-in-place agreements	$	1,053
Leasing commissions and other		246
Total intangible assets	$	1,299
Consideration paid	$	22,033

The Company records the net income from building operations and leases as other income, net, as leasing is not core to the Company’s operations. Building depreciation and amortization for space not occupied by the Company is included in general and administrative expense. Building depreciation and amortization for space occupied by the Company is allocated between general and administrative expense and research and development expense. Components of other income, net, for the three and nine months ended September 30, 2022 and 2021 were as follows (in thousands):

Stockholders’ Equity and Stock-Based Compensation Expense

Stockholders' Equity And Stock-Based Compensation Expense

Note 7. Stockholders’ Equity and Stock-Based Compensation Expense

2021 Registered Direct Offering

On February 12, 2021, the Company completed a common stock offering pursuant to which certain investors purchased 4,081,633 shares of common stock at a price of $49.00 per share. Net proceeds of the offering were approximately $189.8 million after deducting offering expenses.

At-the-Market Common Stock Offering

In March 2020, the Company established an at-the-market offering program (“ATM”) to sell, from time to time, shares of Company common stock having an aggregate offering price of up to $100 million in transactions pursuant to a shelf registration statement that was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on May 5, 2020. The Company is obligated to pay a commission of 3.0% of the gross proceeds from the sale of shares of common stock in the offering. The Company is not obligated to sell any shares in the offering.

There were no common stock sales under the ATM during the three and nine months ended September 30, 2022 and 2021.

Common Stock Warrants

In August 2018, the Company issued warrants to purchase up to an aggregate of 9.1 million shares of its common stock in conjunction with an offering of its common stock. 

The Company did not receive any proceeds from exercise of common stock warrants during the three and nine months ended September 30, 2022.

The Company did not receive any proceeds from exercise of common stock warrants during the three months ended September 30, 2021. During the nine months ended September 30, 2021, the Company received proceeds of $0.7 million from the exercise of 0.6 million shares pursuant to warrants.

There were no common stock warrants outstanding as of September 30, 2022.

Stock Option and Performance Award Activity in 2022

During the nine months ended September 30, 2022, stock options and unvested Performance Awards outstanding under the Company’s stock option plans changed as follows:

	Stock Options	Performance Awards
Outstanding as of December 31, 2021	2,663,727	138,055
Options granted	4,000	—
Options exercised	(194,264)	—
Options forfeited/canceled	(22,139)	(130,913)
Outstanding as of September 30, 2022	2,451,324	7,142

The weighted average exercise price of options outstanding at September 30, 2022 was $11.03. As outstanding options vest over the current remaining vesting period of 1.7 years, the Company expects to recognize stock-based

compensation expense of $4.9 million. If and when outstanding Performance Awards vest, the Company will recognize stock-based compensation expense of $0.1 million over the implicit service period.

During the three months ended September 30, 2022, there were 18,740 stock options exercised with cash proceeds to the Company totaling $136,000.

During the nine months ended September 30, 2022, there were 194,264 stock options exercised. Of the stock options exercised, 94,399 stock options were net settled in satisfaction of the exercise price, with no cash proceeds received. Cash proceeds to the Company for options not net settled totaled $466,000 during the nine months ended September 30, 2022.

During the nine months ended September 30, 2022, a total of 57,143 shares of restricted stock awards expired as performance criteria related to these Performance Awards were not attained. These shares of restricted stock were returned to the 2008 Equity Incentive Plan, which expired in December 2017, and thus were retired.

Stock-based Compensation Expense in 2022

During the three and nine months ended September 30, 2022 and 2021, the Company’s stock-based compensation expense was as follows (in thousands):

2018 Equity Incentive Plan

The Company’s Board of Directors (the “Board”) or a designated committee of the Board is responsible for administration of the Company’s 2018 Omnibus Incentive Plan, as amended (the “2018 Plan”) and determines the terms and conditions of each option granted, consistent with the terms of the 2018 Plan. The Company’s employees, directors, and consultants are eligible to receive awards under the 2018 Plan, including grants of stock options and Performance Awards. Share-based awards generally expire 10 years from the date of grant. The 2018 Plan, as amended on May 5, 2022, provides for issuance of up to 5,000,000 shares of common stock, par value $0.001 per share, subject to adjustment as provided in the 2018 Plan.

When stock options or Performance Awards are exercised net of the exercise price and taxes, the number of shares of stock issued is reduced by the number of shares equal to the amount of taxes owed by the award recipient and that number of shares are cancelled. The Company then uses its cash to pay tax authorities the amount of statutory taxes owed by and on behalf of the award recipient.

2020 Cash Incentive Bonus Plan

2020 Cash Incentive Bonus Plan [Abstract]

2020 Cash Incentive Bonus Plan

Note 10.  2020 Cash Incentive Bonus Plan

In August 2020, the Board approved the Plan. The Plan was established to promote the long-term success of the Company by creating an “at-risk” cash bonus program that rewards Plan participants with additional cash compensation in lockstep with significant increases in the Company’s market capitalization. The Plan is considered “at-risk” because Plan participants will not receive a cash bonus unless the Company’s market capitalization increases significantly and certain other conditions specified in the Plan are met. Specifically, Plan participants will not be paid any cash bonuses unless (1) the Company completes a merger or acquisition transaction that constitutes a sale of ownership of the Company or its assets (a Merger Transaction) or (2) the Compensation Committee of the Board (the Compensation Committee) determines the Company has sufficient cash on hand, as defined in the Plan. Because of the inherent discretion and uncertainty regarding these requirements, the Company has concluded that a Plan grant date has not occurred as of September 30, 2022.

Plan participants will be paid all earned cash bonuses in the event of a Merger Transaction.

The Company’s market capitalization for purposes of the Plan is determined based on either (1) the closing price of one share of the Company’s common stock on the Nasdaq Capital Market multiplied by the total issued and outstanding shares and options to purchase shares of the Company, or (2) the aggregate consideration payable to security holders of the Company in a Merger Transaction. This constitutes a market condition under applicable accounting guidance.   

The Plan triggers a potential cash bonus each time the Company’s market capitalization increases significantly, up to a maximum $5 billion in market capitalization. The Plan specifies 14 incremental amounts between $200 million and $5 billion (each increment, a “Valuation Milestone”). Each Valuation Milestone triggers a potential cash bonus

award in a pre-set amount defined in the Plan. Each Valuation Milestone must be achieved and maintained for no less than 20 consecutive trading days for Plan participants to be eligible for a potential cash bonus award. Approximately 58% of each cash bonus award associated with a Valuation Milestone is subject to adjustment and approval by the Compensation Committee. Any amounts not awarded by the Compensation Committee are no longer available for distribution.

If the Company were to exceed a $5 billion market capitalization for no less than 20 consecutive trading days, all Valuation Milestones would be deemed achieved, in which case cash bonus awards would range from a minimum of $139.1 million up to a hypothetical maximum of $322.3 million. Payment of cash bonuses is deferred until such time as (1) the Company completes a Merger Transaction, or (2) the Compensation Committee determines the Company has sufficient cash on hand to render payment (each, a “Performance Condition”), neither of which may ever occur. Accordingly, there can be no assurance that Plan participants will ever be paid a cash bonus that is awarded under the Plan, even if the Company’s market capitalization increases significantly.

The Plan is accounted for as a liability award. The fair value of each Valuation Milestone award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each of the 14 Valuation Milestones, when a Performance Condition is considered probable of being met.   

In October 2020, the Company achieved the first Valuation Milestone. Subsequently, the Compensation Committee approved a potential cash bonus award of $7.3 million in total for all Plan participants, subject to future satisfaction of a Performance Condition.

During the year ended December 31, 2021, the Company achieved 11 additional Valuation Milestones triggering potential Company obligations to all Plan participants from a minimum of $93.7 million up to a hypothetical maximum of $225.0 million, to be determined by the Compensation Committee and contingent upon future satisfaction of a Performance Condition. However, no compensation expense was recorded since no grant date has occurred and no Performance Conditions are considered probable of being met. There is no continuing service requirement for Plan participants once the Compensation Committee approves a cash bonus award.

No Valuation Milestones were achieved during the three and nine months ended September 30, 2022.

No actual cash payments were authorized or made to participants under the Plan through November 7, 2022.

Securities Class Actions and Shareholder Derivative Actions

Between August 27, 2021 and October 26, 2021, four putative class action lawsuits were filed alleging violations of the federal securities laws by the Company and certain named officers. The complaints rely on allegations contained in Citizen Petitions submitted to FDA, and allege that various statements made by the defendants regarding simufilam were rendered materially false and misleading. The Citizen Petitions were all subsequently denied by FDA. These actions were filed in the U.S. District Court for the Western District of Texas. The complaints seek unspecified compensatory damages and other relief on behalf of a purported class of purchasers of the Company’s securities. On June 30, 2022, a federal judge consolidated the four class action lawsuits into one case and appointed a lead plaintiff and a lead counsel. Lead plaintiff filed a consolidated amended complaint on August 18, 2022 on behalf of a putative class of purchasers of the Company’s securities between September 14, 2020 and July 26, 2022. Briefing on defendants’ motion to dismiss is scheduled to be completed by January 23, 2023. The Company believes the claims are without merit and intends to defend against these lawsuits vigorously. The Company is unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

On November 4, 2021, a related shareholder derivative action was filed, purportedly on behalf of the Company, in the U.S. District Court for the Western District of Texas, asserting claims under the U.S. securities laws and state fiduciary duty laws against certain named officers and the members of the Company’s board of directors. This

complaint relies on the allegations made in Citizen Petitions that were submitted to (and subsequently denied by) FDA. The complaint alleges, among other things, that the individual defendants exposed the Company to unspecified damages and securities law liability by causing it to make materially false and misleading statements, in violation of the U.S. securities laws and in breach of their fiduciary duties to the Company. The derivative case seeks, among other things, to recover unspecified compensatory damages on behalf of the Company arising out of the individual defendant’s alleged wrongful conduct. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants. Since November 4, 2021, three additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, and one in Texas state court (Travis County District Court). All four actions have been stayed pending the resolution of the motions to dismiss in the securities class actions. On July 5, 2022, the three federal court actions were consolidated into a single action.

On August 19, 2022, a shareholder derivative action was filed, purportedly on behalf of the Company, in the Delaware Court of Chancery, asserting claims under state fiduciary duty laws against certain named officers and members of the Company’s board of directors. The complaint alleges, among other things, that the individual defendants breached their fiduciary duties by approving the 2020 Cash Incentive Bonus Plan in August 2020. The complaints seek unspecified compensatory damages and other relief. Although the plaintiff in this derivative case does not seek relief against the Company, the Company has certain indemnification obligations to the individual defendants.

The Company is unable to estimate the possible loss or range of loss, if any, associated with these lawsuits.

Significant Accounting Policies [Abstract]

Use Of Estimates

Use of Estimates

The Company makes estimates and assumptions in preparing its condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to manufacturing agreements and research collaborations. Actual results could differ from these estimates and assumptions.

Cash And Cash Equivalents And Concentration Of Credit Risk

Cash and Cash Equivalents and Concentration of Credit Risk

The Company invests in cash and cash equivalents. The Company considers highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered cash equivalents include money market accounts and funds, certificates of deposit, and U.S. Treasury securities. The Company maintains its cash and cash equivalents at one financial institution.

Fair Value Measurements

Fair Value Measurements

The Company recognizes financial instruments in accordance with the authoritative guidance on fair value measurements and disclosures for financial assets and liabilities. This guidance defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. The guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:

Level 1 includes quoted prices in active markets.

Level 2 includes significant observable inputs, such as quoted prices for identical or similar securities, or other inputs that are observable and can be corroborated by observable market data for similar securities. The Company uses market pricing and other observable market inputs obtained from third-party providers. It uses the bid price to establish fair value where a bid price is available. The Company does not have any financial instruments where the fair value is based on Level 2 inputs.

Level 3 includes unobservable inputs that are supported by little or no market activity. The Company does not have any financial instruments where the fair value is based on Level 3 inputs.

If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The fair value of cash and cash equivalents was based on Level 1 inputs at September 30, 2022 and December 31, 2021.

Business Segments

Business Segments

The Company reports segment information based on how it internally evaluates the operating performance of its business units, or segments. The Company’s operations are confined to one business segment: the development of novel drugs and diagnostics.

Proceeds From Grants

Proceeds from Grants

During the three months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.4 million and $2.0 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the nine months ended September 30, 2022 and 2021, the Company received reimbursements totaling $0.9 million and $3.5 million pursuant to NIH research grants, respectively. The Company records the proceeds from these grants as reductions to its research and development expenses.

Stock-Based Compensation

Stock-based Compensation 

The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. This model requires the input of subjective assumptions including expected stock price volatility, expected life and estimated forfeitures of each award. These assumptions consist of estimates of future market conditions, which are inherently uncertain, and therefore, are subject to management's judgment. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years.

The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit

service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria.

Net Loss Per Share

Net Loss per Share

The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options.  There is no difference between the Company’s net loss and comprehensive loss. The numerators and denominators in the calculation of basic and diluted net loss per share were as follows (in thousands, except net loss per share data):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Numerator:
Net loss	$	(20,257)	$	(9,562)	$	(57,112)	$	(18,213)
Denominator:
Shares used in computing net loss per share, basic and diluted		40,050		39,957		40,009		39,218
Net loss per share, basic and diluted	$	(0.51)	$	(0.24)	$	(1.43)	$	(0.46)
Dilutive common stock options excluded from net loss per share, diluted		1,946		2,350		2,064		2,219

The Company excluded common stock options outstanding, along with 57,143 restricted stock awards, from the calculation of net loss per share, diluted, because the effect of including outstanding options and warrants would have been anti-dilutive. The 57,143 restricted stock awards expired during the nine months ended September 30, 2022.

Fair Value Of Financial Instruments

Fair Value of Financial Instruments   

Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments.

Research Contract Costs And Accruals

Research Contract Costs and Accruals

The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable. Related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs.

Incentive Bonus Plan

Incentive Bonus Plan

In 2020, the Company established the 2020 Cash Incentive Bonus Plan (the “Plan”) to incentivize Plan participants. Awards under the Plan are accounted for as liability awards under Accounting Standards Codification (ASC) 718 “Stock-based Compensation”. The fair value of each potential Plan award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each Plan award, when a Performance Condition (as defined below) is considered probable of being met. See Note 10 for further discussion of the Plan.

Leases

Leases

The Company recognizes assets and liabilities that arise from leases. For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments during the lease term, in the condensed consolidated balance sheets. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities. As the Company`s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Property And Equipment

Property and equipment

Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is recorded using the straight-line method over the estimated useful lives of the assets. Owned buildings and related improvements have estimated useful lives of 39 years and approximately 10 years, respectively. Tenant improvements related to leased space are amortized using the straight-line method over the useful lives of the improvements or the remaining term of the corresponding leases, whichever is shorter. The remaining term of the corresponding leases is approximately 1.6 years.

Property and equipment are reviewed for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If property and equipment are considered to be impaired, an impairment loss is recognized.

Intangible Assets

Intangible assets

Acquired intangible assets are recorded at fair value at the date of acquisition and primarily consist of lease-in-place agreements and leasing commissions. Intangible assets are amortized over the estimated life of the lease-in-place agreements, which is approximately 1.5 years at September 30, 2022.

Intangible assets are reviewed for impairment on an annual basis, and when there is reason to believe that their values have been diminished or impaired. If intangible assets are considered to be impaired, an impairment loss is recognized.

Income Taxes

Income Taxes 

The Company accounts for income taxes under the asset and liability method.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance.

The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s condensed consolidated financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense.
