After rumors surfaced that Grubhub (NYSE:GRUB) hired financial advisors to help it steer a sale of the company, the food delivery service declared it most definitely was not shopping its business, and had no plans to do so. But maybe it ought to rethink that, as a sale looks like the one chance Grubhub has for growth.While Grubhub had reported profits of $99 million, or $1.12 per share, as recently as 2017, analysts are forecasting it will post a fourth quarter loss of $3.7 million, and full-year profits will be cut to just a third of where they were last year, or $0.63 per share. Grubhub cut its own revenue and profit forecast for the year when it reported earnings back in October, citing weak order frequency as one of the reasons. Because there are so many meal delivery companies now, and discounting has become the norm to attract both consumers and restaurants, no one is making any money, with Uber Eats running a near $1 billion deficit over the first nine months of 2019. Unless there is industry consolidation, with companies like Grubhub selling themselves or buying a rival, a war of attrition will likely continue.
