Warrant Dividend Distribution [Text Block] | 13. Warrant Dividend Distribution On January 3, 2024, the Company made a distribution to the holders of record of the Company’s common stock in the form of warrants to purchase shares of common stock. Each holder of record of the Company's common stock as of the close of business on December 22, 2023 received four warrants for every 10 shares of common stock (rounded down for any fractional warrant) resulting in the issuance of approximately 16.9 million warrants. Each warrant entitled the holder to purchase, at the holder’s sole expense and exclusive election, at an exercise price of $33.00 per warrant, one and one-half shares of common stock (rounded down for any fractional shares). Payment for shares of common stock upon exercise of warrants was required to be in cash. On April 15, 2024, the Company announced that all outstanding warrants would be redeemed on May 7, 2024 (the “Redemption Date”). The redemption price was equal to 1/10 of $0.01 per warrant. The warrants were exercisable at any time starting on January 3, 2024 until the business day prior to the Redemption Date. There are no remaining warrants currently outstanding. The warrants were subject to the terms and conditions of the Warrant Agreement (including Form of Warrant), dated January 3, 2024, between Cassava Sciences, Inc., Computershare Inc., and Computershare Trust Company, N.A. as filed in a Current Report on Form 8-K with the SEC on January 3, 2024. The warrants were listed and traded separately from the Company's common stock on the Nasdaq Capital Market under the ticker “SAVAW”. From January 3, 2024 to March 31, 2024, a total of approximately 674,000 warrants were exercised resulting in net proceeds to the Company of approximately $22.3 million. The Company issued approximately 1.0 million shares of common stock from the exercise of warrants through March 31, 2024. Subsequent to March 31, 2024 and through the Redemption Date, a total of approximately 3.15 million warrants were exercised resulting in gross proceeds to the Company of approximately $104.0 million. The Company issued approximately 4.7 million shares of common stock from the exercise of warrants from March 31, 2024 through the Redemption Date. Gross proceeds for the year ended December 31, 2024 from the warrant distribution totaled approximately $126.3 million from the issuance of approximately 5.7 million common shares at $22.00 per share. Total net proceeds of the warrant distribution were approximately $123.6 million after deducting exercise expenses and commissions. After the first $20 million of gross proceeds, the Company was obligated to pay a commission of 2.5% of the gross proceeds from the sale of shares of common stock from warrant exercises to the Company's financial advisor for the warrant distribution. Total cost of warrant exercises through the Redemption Date were approximately $2.7 million. Costs of the warrant distribution totaling approximately $537,000 were recorded as general and administrative expenses in the statements of operations upon distribution of the warrants on January 3, 2024. The outstanding warrants were classified as liabilities in accordance with ASC 480 and ASC 815, which requires the warrants to be measured at initial fair value on January 3, 2024 and at each reporting period thereafter, with the changes in fair value recognized as a non-cash gain or loss in our consolidated statements of operations. As of December 31, 2024, there were no warrants outstanding.
