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, is the only drug to improve axonal transport, the information highway of the nerve cell, by attacking multiple neurotoxic proteins ▪ Two phase 2a clinical trials: ▪ AD trial run by Alzheimer's Disease Cooperative Study (ADCS) ▪ AD and PD trial ▪ 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

THE STATE OF NEURODEGENERATIVE DISEASES ▪ 5.8 million people in the US and 44 million people worldwide are estimated to suffer from AD ▪ PD affects an estimated one million people in the U.S. and as many as 10 million globally ▪ Total costs of care for people with Alzheimer's and other dementias could top $1.1 trillion in 2050 ▪ From 1998 to 2018 there were over 500 failed attempts at developing Alzheimer's drugs, primarily focused on amyloid plaque ▪ The sector needs to rethink dementia, develop new approaches and create new drugs 4

CHANGE IN CAUSES OF DEATH FROM 2000 TO 2018 5 • Breast Cancer - 13% • Colon Cancer - 21% • Heart Disease - 21% • Stroke - 24% • HIV - 67% • Parkinson's + 84% • Alzheimer's + 112%

Chronic and acute brain insults lead to high levels of neurotoxic proteins, to inflammation and neurodegeneration Attacking one neurotoxic protein results in minimal effect ANVS401 is the only drug to attack multiple neurotoxic proteins simultaneously Amyloid β AD / PD - A β Targeting Compounds ANNOVIS' DRUG ATTACKS MULTIPLE NEUROTOXIC PROTEINS Tau Tauopathies - AD - Tau Targeting Compounds aSynuclein PD / AD - aSYN Targeting Compounds 6 Activated Microglia = High Inflammation

NEUROTRANSITTERS THAT TRAVEL ACCROSS THE AXON Adrenaline Noradrenaline Dopamine HOW NERVE CELLS WORK In healthy nerve cells little packages containing neurotransmitters or nerve growth factors travel unimpaired from the cell body through the axon to the synapse. SOMA & CELL BODY DENDRITES Serotonin Gaba Acetylcholine Glutamine Endorphins SYNAPSE 9 Neurotoxic proteins limit the flow and speed at which neurotransmitters travel along the axon resulting in compromised nerve function THE INFORMATION HIGHWAY

11 RESULTS IN HUMANS ANVS401 Lowers Neurotoxic Proteins in Cerebrospinal Fluid (CSF) of Mild Cognitive Impaired (MCI) Patients ▪ In this proof - of - concept study, ANVS401 lowers the levels of APP/Aβ, tau/p - tau and αSYN back to the levels seen in healthy volunteers ▪ It lowers the levels of the three neurotoxic proteins causing AD and PD Maccecchini et al: JNNP 2012; 83: 894 - 902

NEURODEGENERATION IS AN AXONAL TRANSPORT DISEASE Axonal transport is responsible for: Normal Transport The Normal Flow and Speed of vesicles carrying BDNF across the axon. ▪ Neurotransmitters GABA (anxiety), ACh (cognition), dopamine (movement), serotonin (mood) ▪ Neurotrophic factors NGF, BDNF ▪ All communication within and between nerve cells ' Axonal transport disruption is linked to human neurological conditions.

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. 18 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.
