Amazon strikes a deal with Grubhub as the food-delivery business struggles.

Financial turmoil in the food-delivery industry is presenting new opportunities for Amazon.

The e-commerce giant struck a deal on Wednesday with Grubhub that allows Amazon Prime subscribers in the United States to forgo delivery fees on orders from certain restaurants, according to a statement by Just Eat, the Dutch company that owns Grubhub. The agreement also gives Amazon the option to acquire 2 percent of Grubhub, a stake that could eventually grow to 15 percent.

Highlighting the shifting views toward the food-delivery businesses, Just Eat is exploring ways to offload Grubhub roughly two years after paying $7.3 billion to acquire it. The industry’s prospects have been badly bruised as pandemic restrictions have lifted and demand for restaurant delivery has diminished. Labor shortages and increased government regulation have added new costs.

Just Eat, the largest food-delivery platform in Europe, said it would continue exploring a partial or full sale of Grubhub amid pressure from investors to improve its business. Grubhub controls about 13 percent of the U.S. meal delivery market, versus nearly 60 percent for DoorDash and 24 percent for Uber Eats, and Grubhub records lower sales per customer than its main rivals, according to Bloomberg Second Measure. Just Eat’s stock is down more than 60 percent this year.

Amazon also owns a stake in Deliveroo, a struggling British food-delivery service whose shares are down about 50 percent this year. Delivery Hero, another European food-delivery firm, has seen its stock price fall more than 60 percent. Shares of Uber and DoorDash are down nearly 50 percent this year.
