Sales have grown, year-on-year, for Beyond Meat, maker of plant-based meat substitutes. But comparing one quarter to another, sales have stalled. Gross margin has slumped, and not only has Beyond not made a profit in any of its four years of trading, but its losses have worsened. Currently it is incurring $9 of costs for every $8 of sales. It’s little surprise that it is highlighting to the stock market its high hopes for new deals with McDonalds, PepsiCo and others.
