DoorDash sees strong quarterly growth in sales and orders but warns of big costs

The article claims DoorDash reported a 38% revenue increase in the fourth quarter, attributing it to new U.S. customers and services, while also warning of significant costs. Verification Source 1 mentions DoorDash as being 'in focus' and discusses a positive first-quarter outlook, but it does not directly corroborate the specific 38% revenue growth figure for the fourth quarter. As a breaking news alert, and without direct corroboration of the central claim, the factual score is capped.
