Current Treatment Options 15
Acetylcholinesterase Inhibitors Massively flawed class of drugs that has been the only option for the last 20 years • Only works temporarily (~6 months on average). With use, the brains receptors are desensitized, and the drug’s efficacy is lost • Acetylcholinesterase Inhibitors generated >$5 billion in sales in 2019 • Marred by side effects, which result in patients discontinuing treatment due to diminished quality of life / limited efficacy Acetylcholinesterase Inhibitors stats: 8 out of 10 4.5 out of 10 AD patients start out on an Remain on therapy at 12 months due to Acetylcholinesterase Inhibitor side-effects 12 million 30% Prescriptions dispensed per year Discontinue by the 4th month of use Source: Alpha Cognition presentation (Symphony Health data), JAMA, NIH Note: 16
Amyloid Plaque Treatments Billions of dollars and decades of time spent pursuing the amyloid thesis • An academically strong thesis, years of failed trials have shown that this is likely the wrong strategy for addressing Alzheimer’s • Amyloid plaque is associated with Alzheimer’s disease, but it appears that clearing plaque on its own is insufficient for improving symptoms • Big pharma has mostly focused on the amyloid plaque approach with Biogen’s recently approved Aduhelm and Eli Lilly’s donanemab (received BTD on 6/24/21) both being drugs that target clearing amyloid plaque (albeit slightly different targets) • Amyloid plaque treatments have lacked clinical results, are inefficient to administer intravenously, require multiple MRI’s, carry a hefty price tag and consistently have troubling side effects such as brain swelling and microhemorrhages Source: Washington Post, NIH, FDA, Eli Lilly, New York Times, Harvard Health Note: 17
Aduhelm – Troubling FDA Decision Aduhelm was approved despite opposition from the FDA advisory committee • Patient groups have been desperate for any treatment leaving the FDA with the thought that something/anything was better than nothing • 3 out of the 11 experts on the FDA CNS committee resigned over the approval of Aduhelm • In two phase 3 studies, one study outright failed (Engage) while the other study (Emerge) still failed to improve cognition but did improve relative to the placebo in the high-dose treatment • Aduhelm did show an improvement in αβ-42, p-tau and t-tau biomarkers • The clearing of amyloid plaque is what led the FDA to grant Biogen accelerated approval • 34% of patients had brain-swelling, ~19% had microhemorrhages, and ~92% of patients had some form of adverse event “There is no good evidence that reducing amyloid leads to meaningful changes in the clinical course of the disease” - Dr. Aaron Kesslheim (Professor of Medicine at Harvard Medical School in a WSJ article published on 6/8/21) Source: Biogen, Wall Street Journal, Reuters, FDA Note: 18
Simufilam 19
A Unique Mechanism of Action 10+ years of in-house research leading to Simufilam • Simufilam is a proprietary, small molecule drug taken orally to treat Alzheimer’s • The mechanism of action reduces both neurodegeneration and neuroinflammation • Flawless safety profile • Simufilam aims to restore the normal shape and function of a scaffolding protein in the brain called Filamin A (FLNA). Altered Filamin A is critical in the formation of amyloid plaque. The hypothesis is that Simufilam bonds to altered FLNA, restores its proper shape and thus stops the production of amyloid plaque in the brain • Simufilam is a disease-modifying drug not one that is solely focused on alleviating symptoms • Our research suggests that the small-molecule approach targeting misfolded proteins has a long-term effect Source: Cassava Sciences, Joe Springer Note: See appendix for mechanism of action 20
Simufilam Clinical Results A history of safety, cognition improvements and improvements in biomarkers • Phase 2b results were released in September of 2020 • 28-day double-blind, randomized, placebo-controlled, multi-center study • Safe and well-tolerated • 98% response rate in biomarkers for Tau/p-Tau, neuroinflammation, neurodegeneration (25% decrease in tau/Aβ42 ratio) • Improvements seen in cognition with the CANTAB test (improvements over the placebo group in both episodic memory and spatial working memory) • 2b results replicated prior clinical results • 6-month interim analysis of the 12-month open-label study • Reported on the first 50 patients who’ve completed 6 months of treatment • Cognition scores improved by 1.6 points on ADAS-Cog 11 (10% mean improvement from baseline) • Dementia-related behavior improved by 1.3 points on NPI (Neuropsychiatric Inventory) Source: Cassava Sciences, Cambridge Cognition, NCBI, Alz.Org Note: 21

The study is double-blind, randomized, placebo-controlled Symptomatic improvement phase 3 trial: This 600 patient, 12-month study has the goal of demonstrating improved 2 cognition (above baseline) and health function in subjects treated with Simufilam compared to placebo Disease-modifying effects phase 3 trial: This 1,000 patient 18-month study has the goal of demonstrating a slower 3 rate of decline in cognition and health-function in subjects treated with Simufilam compared to placebo Source: Cassava Sciences Note: All trials utilize the ADAS-Cog test for the primary cognition endpoint. The two phase 3 trials use the ADCS-ADL scale as the health function endpoint 24
FDA 25
A Change in the FDA’s Stance There are 4 distinct approaches for making drugs available as rapidly and safely as possible: 1 Fast Track Designation: Breakthrough Therapy Designation: 2 Eli Lilly received Breakthrough Therapy Designation on June 24th, 2021 Accelerated Approval: 3 Biogen received Accelerated Approval for Aduhelm on June 7th, 2021 4 Priority Review: The FDA now views Alzheimer’s as a fatal disease. By approving Biogen’s drug and granting Eli Lilly BTD, the FDA has effectively lowered the bar for new drug approval Source: Eli Lilly, Biogen, FDA Note: 26
Possible Breakthrough Therapy Designation “the short version is yes, yes, and yes. We're very, very conscious, more than anyone we've been focusing on Alzheimer's 24/7 for about twelve years now” - Remi Barbier when asked about possible BTD in a Being Patient Interview on 3/1/21 Source: Being Patient Note: 27

We view this as a free option We believe the addition of these two data sets will serve as incremental positives to the 9-month cognition & safety data Source: NIH Publication, Cassava Sciences Note: 31
Reason for Optimism Consistent & convincing science • Simufilam has been consistent in showing improvements in cognition, behavior, relevant biomarkers and has shown to be safe at every stage of clinical testing • There’s scientific basis for small molecule drugs addressing misfolded proteins having a lasting effect Bullish management • Why would management willingly present on the biggest stage in the world for Alzheimer’s if they had lousy data? • Remi Barbier (Founder/CEO) is struggling to contain his excitement at every public appearance • Management and insiders own > 5% & have not sold despite the 1,000%+ increase in stock price YTD It's the consistency of data from basic research to the animal data, to the CSF biomarkers, to the early cognition, to the open label study. There's a consistent theme that, in my opinion, the world of Alzheimer's disease R&D has never seen before. - Remi Barbier (CEO/Founder of Cassava Sciences in a Being Patient interview on 2/26/21) “I know the science, I know the data, I know the disease, and this stuff looks promising and I'm putting my money where my mouth is” - Remi Barbier (Fortune interview published on 6/8/21) Source: Joe Springer, Being Patient, Fortune Note: 32

Three Multi-Billion Dollar “Call Options” Other Central Nervous Systems (CNS) applications 1 Possible use in diseases such as Parkinson’s, ALS, Rett’s syndrome, Huntington’s disease and even oncology Prophylactic use 2 Potential for Simufilam to be taken preventatively to eliminate or severely delay the onset of symptoms associated with Alzheimer’s SavaDx 3 A blood-based diagnostic test that could massively increase the total addressable market (TAM) for Simufilam with earlier Alzheimer’s diagnosis Source: Note: 42
Other CNS Applications Multiple billion-dollar opportunities besides Alzheimer’s • CNS = central nervous system • There is evidence that restoring misfolded proteins could apply to other CNS diseases • We estimate there are 15-20 million current dementia cases that aren’t Alzheimer’s • Vascular dementia & Lewy Body dementia combined will likely be a $25 billion+ market • Parkinson’s is expected to be an ~$11.5 billion market by 2029 • Other potential use cases such as Rett’s syndrome, Huntington’s disease, ALS and more • Protein misfolding also appears to be a cause of cancer leading to possible exploration into oncology • Cassava Sciences is focusing on Alzheimer’s first before treating other diseases Source: Nature, NCBI, Alzheimer’s Association, Polaris Market Research, PubMed.gov, Global Data, NCBI Note: 43
Prophylactic Use The ultimate upside case where all previous valuations are irrelevant • Amyloid plaques begin forming up to 20 years before AD symptoms appear • Prevention is the key to solving Alzheimer’s • Simufilam might be used preventatively due to the following: • Excellent safety profile • Oral tablet • Upstream of amyloid plaque • SavaDx allowing for early diagnosis • Estimated 250-million person TAM by 2050 that would be a $100 billion+ annual opportunity even with a 96%-98% discount in pricing 2 Billion 50% 25% ~250 Million Estimated Number of Assumption of Those % of Americans Aged 45+ Estimated Market Size for People Worldwide Ages Worldwide With Access to Using a Statin (Model for Preventative Alzheimer’s 60+ by 2050 (per WHO) Healthcare in 2050 Whole World) Disease Drug Source: World Health Organization, Harvard Health, United Nations Note: 44
SavaDx A possible companion to Simufilam or a significant value driver in its own right • SavaDx detected >10-fold differences between patients with and without Alzheimer’s in blinded studies • Could massively increase the TAM for Simufilam by allowing for earlier diagnosis and a longer resulting treatment period • Current Alzheimer’s diagnosis tools leave much to be desired through their cost, inaccuracy or invasive nature • Cassava will be presenting phase 2b results at AAIC • SavaDx alone could be worth billions if widely used as an Alzheimer’s diagnosis tool Source: Cassava Sciences, Company press releases Note: 45
Conclusion 46
Conclusion Why are we so confident in the 9 and 12-month results? • Simufilam is the first in a new class of drug candidates that target altered Filamin A, a proteopathy in Alzheimer’s disease • Small molecules targeting misfolded proteins have been shown to have a lasting persistent impact • Scientific belief that Simufilam’s mechanism of action could be enduring for years • Consistently stellar safety profile • Simufilam targets both neuroinflammation and neurodegeneration • 6-month and 12-month biomarker data will confirm what the cognition and behavioral results have shown • Bullish (yet credible) CEO who has clearly telegraphed consistent and positive upcoming data Source: Note: 47
Conclusion (Cont..) Next steps • Positive 9-month cognition & safety data coupled with 6-month biomarkers and the upcoming 12-month data will validate Simufilam as a disease-modifying drug • Two phase 3 trials will begin this year and the company has sufficient cash to pay for both studies • Results from the cognition maintenance study (CMS) should come in early 2022 • Material share price appreciation due to groundbreaking data results along with eventual Breakthrough Therapy Designation (BTD) Source: Note: 48
