3 ▪ Annovis is developing drugs for Alzheimer's (AD) and Parkinson's disease (PD), including the orphan indication Alzheimer's in Down Syndrome (AD - DS) ▪ Lead compound - ANVS401 - in Phase 2a clinical trial, is the only drug to improve cognition in AD and motor function in PD patients, as recently announced ▪ ANVS401 reduced inflammation, in PD patients as recently announced. Additional biomarker data to come. ▪ Successful completion of phase 2a clinical trials will validate our approach and allow start of two phase 3 studies HIGHLIGHTS A novel approach to treat neurodegeneration is desperately needed

At 25 days the speed is faster than at baseline and they make fewer mistakes (p<0.04). Right - the comparison between the placebo group and the treated group at 25 days. This graph shows that while the placebo group gets slower, the treated group gets faster (p< 0.04). The lower number shows worse performance. 12 Coordination : Left - Comparison between treated at baseline and at 25 days. The two scores are identical – patients remain stable Right - the comparison is made between the placebo group and the treated group both at 25 days. The placebo treated group shows a marked deterioration in their motor complications compared to the ANVS401 treated group that was stable (p< 0.07). The lower number shows better performance. # of fields coded # of mistakes
LOWERING OF INFLAMMATION IN PD PATIENTS Data from first 14 PD patients 13 The trial measured four inflammatory markers that are prevalent in the brains of AD and of PD patients. Each of the inflammatory markers showed statistically significant reduction after 25 days of treatment with ANVS401 compared to baseline. Inflammatory Marker % Change from Baseline p - Value Complement C3 - 24.9 0.0072 YKL40 - 22.9 0.0213 sTREM2 - 28.2 0.0108 GFAp - 34.6 0.000001

Between Data: ANVS401 - treated group compared to placebo group at 25 days showed an improvement of 3.3 points, or 22% (p= 0.13). This is the first double - blind, placebo - controlled study that shows cognitive improvements in AD patients as measured by ADAS - Cog and functional improvements in PD patients as measured by the Unified Parkinson's Disease Rating Scale (UPDRS).
