Exhibit A

In addition, statements in this prospectus referring to the Lab42 Survey refer to a market survey of 3,000 adults over the age of 18 in the United States conducted by Lab42 Research, LLC, a provider of market research, in October 2020, which we commissioned.

In addition to time spent commuting to and from the store, Americans who grocery shop spend on average approximately 60 hours in-store per year shopping for groceries.¹

¹  Instacart estimate based on responses from 2,450 customers in the Lab42 Survey that a majority of such customers spend 30 minutes to 1 hour grocery shopping in-store per trip, and average weekly trips in 2019 based on FMI, U.S. Grocery Shopper Trends.
