BTIG analyst Peter Saleh wonders if Beyond Meat (BYND) could supply enough product should McDonald's want to expand its plant-based patty test throughout the U.S. Beyond could produce enough product in the near-to-medium term to supply McDonald's restaurants in Canada, Saleh told investors yesterday in a research note. However, the analyst is less convinced about the company's potential to support McDonald's U.S. system, especially if demand grows. McDonald's said yesterday morning that it is expanding the global test of its plant-based burger to include 52 restaurants in Southwestern Ontario. The P.LT., which stands for plant, lettuce and tomato, is made with a Beyond Meat plant-based patty that has been crafted exclusively by McDonald's. Saleh estimates that at least a 5% sales mix would be required to justify making P.L.T. a permanent menu item or expanding the item to the majority of McDonald's Canada's 1,480 units. In the U.S., he believes McDonald's would require at least a similar 5% sales mix to justify the effort. Beyond would need to produce 85M to 100M pounds of the plant-based product to support all 13,900 U.S. locations, the analyst wrote. Assuming the product was introduced nationwide in North America, he believes Beyond would need to produce 95M-115M pounds of product annually, or more than three-times Beyond Meat's food service capacity run-rate for 2019. Saleh has a Buy rating on McDonald's with a $240 price target and does not rate shares of Beyond Meat, which are up 6% to $86.65 in afternoon trading.
