Cassava Sciences, Inc.

Notes to Condensed Consolidated Financial Statement s

(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 six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year 2023. 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, 2022.

Liquidity

The Company has incurred significant net losses and negative cash flows since inception, and as a result has an accumulated deficit of $334.2 million at June 30, 2023. 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.

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.

7

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 June 30, 2023 and December 31, 2022.

﻿

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 and six months ended June 30, 2023, there were no reimbursements received pursuant to National Institutes of Health (“NIH”) research grants. During the three and six months ended June 30, 2022, the Company received reimbursements totaling $0.4 million and $0.5 million, respectively, pursuant to NIH research grants. 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.

﻿

8

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 |  | Six months ended
|  | June 30, |  | June 30,
|  | 2023 |  | 2022 |  | 2023 |  | 2022
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net loss |  | $ | (26,376) |  | $ | (19,328) |  | $ | (50,647) |  | $ | (36,855)
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Shares used in computing net loss per share, basic and diluted |  |  | 41,793 |  |  | 40,015 |  |  | 41,766 |  |  | 39,989
Net loss per share, basic and diluted |  | $ | (0.63) |  | $ | (0.48) |  | $ | (1.21) |  | $ | (0.92)
Dilutive common stock options excluded from net loss per share, diluted |  |  | 2,001 |  |  | 1,937 |  |  | 2,018 |  |  | 2,095

The Company excluded common stock options outstanding from the calculation of net loss per share, diluted, because the effect of including outstanding options would have been anti-dilutive. The Company also excluded 57,143 restricted stock awards from the calculation of net loss per share, diluted, until their expiration in June 2022 because the effect of including restricted stock awards would have been anti-dilutive.

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 prepaids and accruals for estimated ongoing research costs. When evaluating the adequacy of prepaid expenses and 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 prepaid and accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical prepaid and 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 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 0.9 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 0.8 years at June 30, 2023.

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.

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 office complex measures approximately 90,000 rentable square feet. At June 30, 2023, the property was over 60% leased. The Company also occupies approximately 25% of the property.

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.

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

2022 Registered Direct Offering

On November 22, 2022, the Company completed a common stock offering pursuant to which certain investors purchased 1,666,667 shares of common stock at a price of $30.00 per share. Net proceeds of the offering were approximately $47.3 million after deducting offering expenses.

12

At-the-Market Common Stock Offering

On May 1, 2023, the Company established a new 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 $200 million in common stock pursuant to a shelf registration statement that was filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 1, 2023 and became effective immediately upon filing. The Company is obligated to pay a commission of up to 3% 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 six months ended June 30, 2023.

In March 2020, the Company established an at-the-market offering program (“2020 Program”) 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 SEC on May 5, 2020. The Company gave notice of termination for the 2020 Program on April 26, 2023, which was effective May 1, 2023. There were no common stock sales under the 2020 Program through its termination.

Stock Option and Performance Award Activity in 2023

During the six months ended June 30, 2023, 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, 2022 |  | 2,529,448 |  |  | 7,142
Options granted |  | 122,000 |  |  | —
Options exercised |  | (281,175) |  |  | —
Options forfeited/canceled |  | (7,142) |  |  | —
Outstanding as of June 30, 2023 |  | 2,363,131 |  |  | 7,142

The weighted average exercise price of options outstanding at June 30, 2023 was $12.67. As outstanding options vest over the current remaining vesting period of 2.4 years, the Company expects to recognize stock-based compensation expense of $8.8 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 June 30, 2023, there were 262,158 stock options exercised. Of the stock options exercised, 92,066 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 $889,000 during the three months ended June 30, 2023.

During the six months ended June 30, 2023, there were 281,175 stock options exercised. Of the stock options exercised, 97,205 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 $953,000 during the six months ended June 30, 2023.

Stock-based Compensation Expense in 2023

During the three and six months ended June 30, 2023 and 2022, the Company’s stock-based compensation expense was as follows (in thousands):

Total stock-based compensation expense |  | $ | 835 |  | $ | 485 |  | $ | 1,508 |  | $ | 980 |

13

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 no t provide for income taxes during the three and six months ended June 30, 2023, because it has projected a net loss for the full year 2023 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 six months ended June 30, 2022.

Note 9. Commitments

Right-of-use Asset and Liability

The Company had an operating lease for approximately 6,000 square feet of office space in Austin, Texas with an expiration of April 30, 2024. The Company and the landlord consented to early terminate this lease on February 22, 2023 with no continuing obligations.

There was no rent expense for the three months ended June 30, 2023. Rent expense for the three months ended June 30, 2022 totaled $41,000.

Rent expense for the six months ended June 30, 2023 and 2022 totaled $24,000 and $82,000, respectively.

There was no cash paid for operating lease liabilities during the three months ended June 30, 2023. Cash paid for operating lease liabilities during the three months ended June 30, 2022 totaled $41,000.

Cash paid for operating lease liabilities during the six months ended June 30, 2023 and 2022 totaled $24,000 and $82,000, 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

14

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 June 30, 2023.

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

As of December 31, 2022, the Company’s independent directors were participants in the Plan. However, effective March 16, 2023, the Board of Directors amended the Plan to remove all independent directors as participants in the Plan and the independent directors consented to such removal. The independent directors’ share of potential benefits under the Plan were completely forfeited to the Company and will not be allocated to any other participant under the Plan. The Company’s independent directors have no t received, and as a result of such amendment will never receive, any payments under the Plan.

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 67% 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 $111.4 million up to a hypothetical maximum of $289.7 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 $6.5 million in total for all Plan participants (after the March 2023 Plan amendment), 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 $74.9 million up to a hypothetical maximum of $202.3 million (after the March 2023 Plan amendment), 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 2022 or the six months ended June 30, 2023.

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

Note 11. Contingencies

From time to time, the Company may become involved in litigation or other legal proceedings and claims, including U.S. government inquiries, investigations and Citizen Petitions submitted to FDA, and may receive inquiries from government authorities relating to matters arising from the ordinary course of business. The outcome of these proceedings is inherently uncertain. Regardless of outcome, legal proceedings can have an adverse impact on the Company 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 the Company. 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 condensed consolidated financial statements and, as such, no accrual for these matters has been recorded within the condensed consolidated financial statements.

Government Investigations

On November 15, 2021, the Company disclosed that certain government agencies had asked the Company to provide corporate information and documents. These were confidential requests. The Company has been voluntarily cooperating and intends to continue to cooperate with these inquiries. No government agency has informed the Company that it has found evidence of research misconduct or wrongdoing by the Company or its officers, employees or directors. No government agency has filed any claims or charges relating to these inquiries. We cannot predict the outcome or impact of these ongoing matters, including whether a government agency may pursue an enforcement action against the Company 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 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.

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. On May 11, 2023, the court dismissed with prejudice plaintiffs’ claims against (deceased) defendant Nadav Friedmann, PhD, MD, but otherwise denied defendants’ motion to dismiss. Defendants filed an answer to the consolidated amended complaint on July 3, 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, four additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, one in Texas state court (Travis County District Court) and one in the Delaware Court of Chancery. On July 5, 2022, the three federal court actions were consolidated into a single action.

16

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. On January 6, 2023, the plaintiffs filed an amended complaint. Defendants filed a partial answer to the amended complaint on March 10, 2023, and moved to partially dismiss the amended complaint on March 14, 2023. Defendants’ motion to dismiss remains pending. Although the plaintiffs in this derivative case do 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.

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. Our lead therapeutic drug candidate, simufilam, is being evaluated for the proposed treatment of Alzheimer’s disease dementia in Phase 3 clinical studies.

For more than 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 oral treatment for Alzheimer’s disease dementia; 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 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.

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. S ince 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 was discovered and designed in-house and was characterized by our academic collaborators during research activities that were conducted from approximately 2008 to date. SavaDx is being developed in-house with outside collaborators. We own exclusive, worldwide rights to drug and diagnostic assets and related technologies, without royalty obligations to any third party. Our patent protection with respect to simufilam and use of simufilam

20

for Alzheimer’s disease and other neurodegenerative diseases currently runs through 2039 and includes seven issued U.S. patents. In addition, we have patent protection with respect to simufilam for use in treating certain cancers that runs through 2034. Our patent estate further includes patents and patent applications for related compounds and treatments. Corresponding foreign filings have been made for each of the U.S. filings.

About Alzheimer’s Disease

Alzheimer’s disease is a progressive neurodegenerative disorder that affects cognition, function and behavior. As of 2021, there were approximately 55 million people worldwide living with dementia, a figure expected to increase to 139 million by 2050 according to outside sources. The annual global cost of dementia is now above $1 trillion, according to Alzheimer’s Disease International, a charitable organization.

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, an exploratory ‘research use only’ non-safety related biomarker that suggests brain changes from Alzheimer’s disease. Materials labeled as Research Use Only are intended for products that are still under development and are not commercially distributed.

Open-label Study Strategy

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

Open-label Study Top-line 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 NIH. The study was designed to evaluate the long-term safety and tolerability of simufilam 100 mg twice daily for 12 or more months. Another study objective was to assess exploratory efficacy endpoints, such as changes in cognition, and biomarkers.

In January 2023, we announced positive top-line Phase 2 results for our open-label study. The study enrolled over 200 patients with mild-to-moderate Alzheimer’s disease (MMSE 16-26). Endpoints were measured at baseline (study entry) and month 12.

Alzheimer’s is a degenerative disease of the brain. Over time, cognition progressively worsens in the mild-to-moderate stages of Alzheimer’s as the disease takes its toll. ADAS-Cog scores that change minimally (or improve) over 1 year is a highly desirable outcome in a clinical study of patients with mild-to-moderate Alzheimer’s disease.

Top-line Results – mean scores, baseline to month 12 (lower is better, except for MMSE):

ADAS-Cog11 scores changed from 19.1 (±9.2) to 19.6 (±13.3)

21

MMSE scores changed from 21.5 (±3.6) to 20.2 (±6.4)

NPI10 scores changed from 3.2 (±4.6) to 2.9 (±4.6)

GDS scores changed from 1.8 (±1.8) to 1.4 (±1.9)

Response Analysis – baseline to month 12

ADAS-Cog scores improved in 47% of patients; this group had a mean change of -4.7 (±3.8) points (lower is better).

In an additional 23% of patients, ADAS-Cog declined less than 5 points; this group had a mean change of 2.5 (±1.4) points.

Patients with an NPI10 score of zero increased from 42% to 54%, indicating reduced dementia-related neuropsychiatric symptoms after 1 year on simufilam.

Analysis of Efficacy Endpoints

Efficacy outcomes were analyzed by an independent, outside biostatistical consulting firm led by Suzanne Hendrix, PhD. The pre-specified primary efficacy endpoint was change in baseline on ADAS-Cog11, a cognitive scale widely used in Alzheimer’s clinical research. Exploratory endpoints included the Mini-Mental State Examination (MMSE) to assess disease stage by cognitive impairment; the Neuropsychiatric Inventory (NPI10) to assess dementia related behavior; and the Geriatric Depression Scale (GDS). The Full Analysis Set (FAS) population (N=216) was used for the statistical analysis of efficacy endpoints.

Alzheimer’s is a progressive disease. Severity of disease is typically assessed by MMSE score. In this study, mild patients are MMSE 21-26; moderate patients are MMSE 16-20. Mild and moderate sub-groups showed notable differences on changes in ADAS-Cog mean scores, baseline to month 12 (lower is better):

In the mild sub-group, ADAS-Cog scores improved, from 15.0 (±6.3) to 12.6 (±7.8)

In the moderate sub-group, ADAS-Cog scores worsened, from 25.7 (±9.2) to 30.1 (±13.1)

We believe the improvement in ADAS-Cog over 1 year in mild patients taking simufilam is well outside the expected range of historic placebo decline rates from numerous other studies. Figure 1 presents a model of historical declines on ADAS-Cog in early disease (MCI + mild) and mild disease.

Safety Data

Simufilam 100 mg twice daily was generally safe and well tolerated in this open-label study. There were no drug-related serious adverse events. Three treatment-emergent adverse events (TEAEs) occurred in 7% or more of study patients: COVID-19 (12%), urinary tract infection (10%) and headache (9%). Reported TEAEs are based on all study patients who received at least one dose of drug. The top three reasons for patient discontinuations were withdrawal of informed consent (N=14), adverse events (N=13) and patient non-compliance (N=7).

Biomarker Data

Exploratory biomarkers were analyzed from cerebrospinal fluid (CSF) collected from 25 patients in the open-label study who agreed to undergo a lumbar puncture at baseline and again after 6 months of treatment. CSF samples were analyzed blind by our academic collaborator at City University of New York. All CSF biomarkers were ‘research use only’, non-safety-related exploratory biomarkers. We previously announced results of this bioanalysis in a press release dated July 29, 2021.

P-values shown below are baseline vs. 6-month levels by paired t-test:

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 neurofilament light chain (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)

Limitations of Open-label Study and Top-line Results

Data results from our open-label safety study do not constitute, and should not be interpreted as, regulatory evidence of safety or efficacy for simufilam in Alzheimer’s disease. Rigorous evidence for drug safety and efficacy is derived from one or more large, randomized, placebo-controlled studies. The open-label design and size of this study may introduce clinical or statistical bias or may generate results that may not fully distinguish between drug effects and random variation. Different methods of statistical analysis on clinical data from the same study may lead to objectively different numerical results. These and other statistical and clinical features of our open-label study add complexity or limitations to the scope of data interpretation. In addition, ‘top-line data’ is a summary of the clinical data prior to the completion of a full and final audit or quality-control of the clinical database. We communicated top-line data so that stakeholders had timely access to a summary of the study’s findings prior to us receiving the final dataset. Final data may change from initial top-line data.

Cognition Maintenance Study

In May 2021, we initiated a Cognition Maintenance Study (CMS). The CMS is a randomized, withdrawal study design. ICH 2 defines this type of study design as follows: “In a randomized withdrawal trial, subjects receiving a test treatment for a specified time are randomly assigned to continued treatment with the test treatment or to placebo (i.e., withdrawal of active therapy) … Any difference that emerges between the group receiving continued treatment and the group randomized to placebo would demonstrate the effect of the active treatment.”

The CMS study design is intended 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. It is a double-blind, randomized, placebo-controlled study of simufilam in patients with mild-to-moderate Alzheimer’s disease. Study patients are randomized (1:1) to simufilam or placebo for six months. To enroll in this study, patients must have previously completed 12 months or more of open-label treatment with simufilam. Final enrollment was 157 patients. See Figure 2.

Figure 2. Cognition Maintenance Study Design

Top-line Results

Simufilam treatment for 6 months slowed cognitive decline by 38% compared to placebo in mild-to-moderate Alzheimer’s disease (MMSE 16-26). The placebo arm declined 1.5 points on ADAS-Cog, and this arm declined at all measured timepoints. The simufilam arm declined 0.9 points on ADAS-Cog, a 38% difference in favor of drug at month 6 (95% CI, – 2.1 to 1.0; not significant for sample sizes). See Table 1 and Chart 1.

Table 1: Results of Randomized Withdrawal Study – cognitive change, full analysis set (FAS)

Full Analysis Set | Simufilam 100 mg (N = 78) | Placebo (N = 77) | Numerical Difference | Percent Difference
6-month Change in ADAS-Cog | 0.9 point Decline | 1.5 point Decline | – 0.6 | 38% in favor of drug

Upon randomization into the CMS, mean baseline MMSE scores were 18.6 and 18.1 for the simufilam and placebo arms, respectively. Mean baseline ADAS-Cog scores were 19.3 and 21.9 for the simufilam and placebo arms, respectively.

Simufilam Drug Effects Favored Patients with Mild Alzheimer’s Disease.

Simufilam treatment for 6 months slowed cognitive decline > 200% compared to placebo in mild Alzheimer’s disease. CMS patients with mild Alzheimer’s (MMSE 21-26) on placebo declined 0.6 points on ADAS-Cog over 6 months as a group. CMS patients with mild Alzheimer’s on simufilam improved 0.6 points over 6 months as a group, a 205% difference in favor of drug (95% CI, – 2.6 to 0.4; not significant for sample sizes). See Table 2 and Chart 2.

Table 2: Results of Randomized Withdrawal Study – cognitive change, mild patients

Mild Patients | Simufilam 100 mg (N= 40) | Placebo (N= 36) | Numerical Difference | Percent Difference
6-month Changes in ADAS-Cog | 0.6 point Improvement | 0.6 point Decline | – 1.1 | 205% in favor of drug

25

Upon randomization into the CMS, mean baseline MMSE scores for mild patients were MMSE 24.0 and MMSE 24.1 for the simufilam and placebo arms, respectively. Mean baseline ADAS-Cog scores for mild patients were 11.0 and 11.2 for the simufilam and placebo arms, respectively.

Simufilam for 18 months stabilized cognition in mild Alzheimer’s disease.

After taking open-label simufilam for 12 months, 76 patients with mild Alzheimer’s disease (MMSE 21-26) enrolled in the CMS and were randomized to receive either simufilam (N=40) or placebo (N=36) for 6 months. Mild patients randomized to simufilam in the CMS showed no material decline in ADAS-Cog scores over 18 months as a group, indicating stable cognition. Mild patients randomized to placebo in the CMS (and therefore withdrawn from simufilam treatment for 6 months) declined by 0.8 points in ADAS-Cog as a group. See Figure 3.

Historical declines on ADAS-Cog over 18 months in Alzheimer's disease (MMSE 20-30), placebo arms vs simufilam treatment.1 Notes: results shown for CLARITY P3 trial of lecanemab; EMERGE and ENGAGE P3 studies of aducanumab; and TRAILBLAZER P3 trial of donanemab; in this figure, the CMS is referred to as the ‘PTI-125-04’ study; ‘Simufilam100mg-Simufilam100mg’ refers to patients who received simufilam in both the open-label phase and the CMS; ‘Simufilam100mg-Placebo’ refers to patients who received simufilam in the open-label phase and placebo in the CMS.

Safety Data

Simufilam 100 mg twice daily was safe and well tolerated in this study. There were no drug-related serious adverse events. No treatment-emergent adverse events (TEAEs) occurred in 5% or more of study participants in the CMS.

Discussion

The CMS was a randomized withdrawal study. Patients who completed 12 months of open-label simufilam treatment were all invited to participate in the CMS. It is not known how long a washout period may be needed to remove lingering drug effects, if any, from prior treatment with open-label simufilam for 12 months.

In this small study of oral simufilam in patients with mild-to-moderate Alzheimer’s disease, the pre-specified cognitive endpoint showed a 38% decline in ADAS-Cog over six months in favor of simufilam, with good drug safety. Effects were pronounced in mild patients. Mean baseline MMSE and ADAS-Cog scores were approximately balanced given the small size of each arm.

Analysis of Efficacy Endpoints

The pre-specified cognition endpoints were analyzed by Pentara Corporation, an independent consulting firm that specializes in complex statistical analysis of clinical trial results. Suzanne Hendrix, PhD, CEO of Pentara, has over 150 peer-reviewed publications of clinical trial results and statistical approaches for clinical trials, many focusing on statistical methodology for Alzheimer’s disease.

Chain of Custody for Clinical Data

Investigator sites collected clinical data from study participants. Sites entered their clinical data directly into an electronic data capture system managed by an independent, outside data management vendor. The data management vendor also maintains the clinical database. The data management vendor transmitted the clinical database directly to Pentara Corporation for analysis.

Study Limitations

The CMS is a proof-of-concept study involving a small number of patients and limited data. Top-line clinical CMS results do not constitute, and should not be interpreted as, regulatory evidence of safety or efficacy for simufilam in Alzheimer’s disease. Rigorous evidence for drug safety and efficacy is derived from one or more large, randomized placebo-controlled Phase 3 studies. The limited size of the CMS may introduce clinical or statistical bias or may generate results that may not fully distinguish between drug effects and random variation. Different methods of statistical analysis on clinical data from the same study may lead to objectively different numerical results. These and other statistical and clinical features of our CMS study add complexity or limitations to the scope of data interpretation. In addition, ‘Top-line data’ is a summary of the clinical data prior to the completion of a full and final audit or quality-control of the clinical database. We are communicating top-line data so that stakeholders may have timely access to a summary of the CMS findings prior to us receiving the final dataset. Final data may change from initial top-line data.

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.

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-cog 1) and function (ADCS-ADL 2) are appropriate co-primary endpoints of efficacy. A clinical scale that combines cognition and function, such as iADRS 3, 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

We have entered into a drug supply agreement with Evonik Industries AG for simufilam. Under the agreement, Evonik supplies and is expected to continue to 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

Our 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. Highlights of this clinical program are summarized in Figure 3. In June 2021, we announced the selection of Premier Research International as our CRO to help conduct our Phase 3 clinical program.

Figure 4. Summary of Our Phase 3 Clinical Program

RETHINK-ALZ and REFOCUS-ALZ

In Fall 2021, we announced initiation of our two Phase 3 studies of simufilam. As of August 3, 2023, a total of over 1,587 patients have been enrolled in our Phase 3 program. The target patient enrollment for the Phase 3 program is over 1,750 patients. We anticipate the completion of patient enrollment for both of our Phase 3 studies by yearend 2023. Patients continue to be 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.

Details of the RETHINK-ALZ Phase 3 study include:

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

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

Patients to be treated for 12 months.

The co-primary efficacy endpoints are ADAS-Cog12 1, a cognitive scale, and ADCS-ADL 2, a functional scale; both are standard clinical tools in trials of Alzheimer’s disease.

A secondary efficacy endpoint is iADRS 3, 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 NPI 4, 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 patients with mild-to-moderate Alzheimer’s disease to be enrolled.

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

Patients to be treated for 76 weeks.

The co-primary efficacy endpoints are ADAS-Cog 1, a cognitive scale, and ADCS-ADL 2, a functional scale; both are widely used clinical tools in trials of Alzheimer’s disease.

A secondary efficacy endpoint is iADRS 3, 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 NPI 4, a clinical tool that assesses the presence and severity of dementia-related behavior.

Phase 3 Entry Criteria Includes a Plasma Assay for Phosphorylated Tau (p-Tau)

We believe plasma levels of pTau proteins can provide independent confirmation of Alzheimer’s neuropathology. RETHINK-ALZ and REFOCUS-ALZ studies use a ‘research use only’, non-safety related exploratory P-tau181 plasma assay to qualify mild-to-moderate Alzheimer’s patients. At the 15 th International Conference on Clinical Trials on Alzheimer’s Disease (CTAD) 2022, a poster presentation indicated a 30 ng/L cut-point showed 100% sensitivity and 88% specificity for Alzheimer’s diagnosis in 22 autopsy-confirmed samples 5. The plasma assay we use does not rely on age, APOE-gene status or complex algorithms to provide a result.

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 study is designed to provide no-cost access to simufilam for one year to Alzheimer’s patients who have successfully completed a Phase 3 study of simufilam.

The open-label extension study is expected to generate long-term safety and tolerability data for (oral) simufilam 100 mg twice daily over 52 weeks. There is no obligation for a patient or a physician to participate in the open-label extension study. Each clinical investigational site and each patient chooses whether to participate in this open-label extension study. Patient enrollment for this study began 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. SavaDx is a research-use only, non-safety related exploratory biomarker.

The regulatory pathway for SavaDx may eventually include formal analytical validation studies and clinical studies that sup port 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 2023.

SavaDx is currently designed as an antibody-based detection system for altered filamin A (FLNA). Working with third parties, we are evaluating the exploratory use of mass spectrometry to detect FLNA, i.e., without the use of antibodies.

Financial Overview

We have yet to generate any revenues from product sales. We have an accumulated deficit of $334.2 million at June 30, 2023. 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 clinical and preclinical 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 enrollment rates of clinical trials for our product candidates, timing of preclinical activities 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 increase 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;

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;

incur costs related to legal proceedings and claims, including U.S. government inquiries; 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 |  | Six months ended |
|  | June 30, |  | June 30, |
|  | 2023 |  | 2022 |  | 2023 |  | 2022 |
Compensation |  | $ | 1,790 |  | $ | 1,849 |  | $ | 3,604 |  | $ | 3,747 |
Contractor fees and supplies |  |  | 22,893 |  |  | 14,820 |  |  | 42,941 |  |  | 27,676 |
Other common costs |  |  | 286 |  |  | 279 |  |  | 544 |  |  | 431 |
|  | $ | 24,969 |  | $ | 16,948 |  | $ | 47,089 |  | $ | 31,854 |

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 and six months ended June 30, 2023, we did not receive reimbursement from NIH research grants. During the three and six months ended June 30, 2022, we received $0.4 million and $0.5 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. 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 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 six months ended June 30, 2023 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, 2022, as filed with the SEC on February 28, 2023.

Results of Operations – Three and Six Months Ended June 30, 2023 and 2022

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 $25.0 million and $16.9 million during the three months ended June 30, 2023 and 2022, respectively. This 47% increase was due primarily to increasing enrollment and costs to conduct the ongoing Phase 3 clinical program and open-label studies in simufilam as well as higher preclinical and drug supply costs compared to the prior year.

Research and development expenses were $47.1 million and $31.9 million during the six months ended June 30, 2023 and 2022, respectively. This 48% increase was due primarily to increasing enrollment and costs to conduct the ongoing Phase 3 clinical program and open-label studies in simufilam as well as higher preclinical and drug supply costs compared to the prior year.

We expect research and development expense to increase in 2023 compared to 2022 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 facility costs for our Company owned office complex in Austin, Texas. 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.

32

General and administrative expenses were $3.8 million and $3.0 million during the three months ended June 30, 2023 and 2022, respectively. The 28% increase was due primarily to $0.4 million increase in stock-based compensation expense due to new grant awards during the period as well as $0.3 million in higher legal expenses due to ongoing legal matters as compared to the prior year.

General and administrative expenses were $8.2 million and $5.9 million during the six months ended June 30, 2023 and 2022, respectively. The 39% increase was due primarily to $1.2 million in higher legal expenses due to ongoing legal matters, a $0.6 million increase in stock-based compensation expense due to new grant awards during the period as well as an increase in headcount and personnel costs compared to the prior year.

We expect general and administrative expense for 2023 will increase compared to 2022 due primarily to stock-based compensation increases due to new grant awards during the period and higher legal and professional fees related to ongoing securities class action and derivative lawsuits, governmental investigations as well the Company’s lawsuit against a hedge fund and certain individuals who we believe executed a “short and distort” campaign against Cassava Sciences.

Interest Income

Interest income was $2.2 million and $0.3 million during the three months ended June 30, 2023 and 2022, respectively.

Interest income was $4.2 million and $0.3 million during the six months ended June 30, 2023 and 2022, respectively.

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

We expect interest income increases in 2023 compared to 2022 due to 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 $203,000 and $275,000 during the three months ended June 30, 2023 and 2022, respectively. Other income, net, was $0.4 million and $0.5 million during the six months ended June 30, 2023 and 2022, respectively. Other income, net, was lower in the three and six months ended June 30, 2023 as occupancy related expenses were higher in 2023 compared to the prior year periods as the Company began occupying approximately 25% of the property beginning late August 2022.

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 June 30, 2023, cash and cash equivalents were $168.4 million.

2022 Registered Direct Offering

On November 22, 2022, we completed a common stock offering pursuant to which certain investors purchased 1,666,667 shares of common stock at a price of $30.00 per share. Net proceeds of the offering were approximately $47.3 million after deducting offering expenses.

33

At-the-Market Common Stock Offering

On May 1, 2023, we established a new 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 $200 million in common stock pursuant to a shelf registration statement that was filed with the SEC on May 1, 2023 and became effective immediately upon filing. We are obligated to pay a commission of up to 3% 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 and six months ended June 30, 2023.

In March 2020, we established an at-the-market offering program (“2020 Program”) 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 gave notice of termination for the 2020 Program effective on April 26, 2023, which was effective May 1, 2023. There were no common stock sales under the 2020 Program through its termination.

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.

As of December 31, 2022, the Company’s independent directors were participants in the Plan. However, effective March 16, 2023, the Board of Directors amended the Plan to remove all independent directors as participants in the Plan and the independent directors consented to such removal. The independent directors’ share of potential benefits under the Plan were completely forfeited to the Company and will not be allocated to any other participant under the Plan. Our independent directors have not received, and as a result of such amendment will never receive, any payments under the Plan.

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 $111.4 million up to a hypothetical maximum of $289.7 million.

The Company’s potential financial obligation to plan participants at June 30, 2023 totaled $6.5 million (after the March 2023 Plan amendment), 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 $74.9 million up to a hypothetical maximum of $202.3 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 2022 or the six months ended June 30, 2023.

No actual cash payments were authorized or made to participants under the Plan as of June 30, 2023, or through the filing date of this Form 10-Q.

34

Use of Cash

Net cash used in operating activities was $33.2 million for the six months ended June 30, 2023, resulting primarily from the net loss of $50.6 million, partially offset by an increase in accounts payable and accrued expenses of $6.7 million, an increase in accrued developmental expenses of $4.8 million, a decrease in in prepaid and other current assets of $4.1 million and stock-based compensation expense of $1.5 million.

Net cash used in operating activities was $34.6 million for the six months ended June 30, 2022, resulting primarily from the net loss reported of $36.9 million, a decrease in accounts payable and accrued expenses of $2.4 million and accrued compensation and benefits of $1.7 million, partially offset by a decrease in in prepaid and other assets of $4.4 million, an increase in accrued developmental expenses of $0.5 million and stock-based compensation expense of $1.0 million.

Net cash used in investing activities during the six months ended June 30, 2023 was $0.4 million as final payment was made on renovations and fixtures for our corporate headquarters.

Net cash used in investing activities during the six months ended June 30, 2022 was $1.9 million related to renovations to an owned building in Austin, Texas, a portion of which serves as our corporate headquarters.

Net cash provided by financing activities during the six months ended June 30, 2023 was $1.0 million, from the exercise of stock options.

Net cash provided by financing activities during the six months ended June 30, 2022 was $0.3 million, from the exercise of stock options.

Property and Leases

We own 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 office complex measures approximately 90,000 rentable square feet. The property is currently over 60% leased. We also occupied approximately 25% of the property beginning late August 2022.

We leased approximately 6,000 square feet of office space pursuant to an operating lease in Austin, Texas expiring in April 2024. We and the landlord consented to early terminate this lease on February 22, 2023 with no continuing obligations.

Other Commitments

We have an accumulated deficit of $334.2 million as of June 30, 2023. 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 and cash equivalents of $168.4 million as of June 30, 2023, which consisted primarily of U.S. Treasury securities and money market accounts.

35

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 June 30, 2023, 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 June 30, 2023 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, investigations and Citizen Petitions submitted to FDA, and may receive inquiries from government authorities relating to matters arising from the ordinary course of business. 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 condensed consolidated financial statements and, as such, no accrual for these matters has been recorded within the condensed consolidated financial statements.

Government Investigations

On November 15, 2021, the Company disclosed that certain government agencies had asked the Company to provide corporate information and documents. These were confidential requests. The Company has been voluntarily cooperating and intends to continue to cooperate with these inquiries. No government agency has informed the Company that it has found evidence of research misconduct or wrongdoing by the Company or its officers, employees or directors. No government agency has filed any claims or charges relating to these inquiries. We cannot predict the outcome or impact of these ongoing matters, including whether a government agency may pursue an enforcement action against the Company 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.

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. On May 11, 2023, the court dismissed with prejudice plaintiffs’ claims against (deceased) defendant Nadav Friedmann, PhD, MD, but otherwise denied defendants’ motion to dismiss. Defendants filed an answer to the consolidated amended complaint on July 3, 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, four additional shareholder derivative actions were filed alleging substantially similar claims, two in the U.S. District Court for the Western District of Texas, one in Texas state court (Travis County District Court) and one in the Delaware Court of Chancery. 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. On January 6, 2023, the plaintiffs filed an amended complaint. Defendants filed a partial answer to the amended complaint on March 10, 2023, and moved to partially dismiss the amended complaint on March 14, 2023. Defendants’ motion to dismiss remains pending. Although the plaintiffs in this derivative case do 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.
