Grubhub Inc. GRUB, +0.61% said Friday that it's working with large-city mayors nationwide to temporarily suspend up to $100 million in commissions for independent restaurants. Grubhub says independent restaurants make up the majority of the delivery company's 350,000+ network of restaurants and more than 80% of orders. Dine-in restaurant traffic is expected to decline 75% in the coming weeks, and pick-up and delivery service will be critical, the company said. Grubhub will also divert money from its Donate the Change charitable program to restaurants and drivers impacted by Covid-19. The program allows customers to round up on their orders to Grubhub and Seamless and donate it to the Grubhub Community Relief Fund. The program raises more than $1 million per month, Grubhub says. Seamless has also announced that it is deferring commission fees, with dine-in activity down as much as 75% and many places barring restaurant activity beyond takeout and delivery. Grubhub stock is up 4.1% in Friday trading, but is down 51.5% over the last year. The S&P 500 index SPX, -1.11% is down 10.7% over the last 12 months.
