America’s largest retailers are weathering the country’s supply chain storm while smaller rivals struggle to secure sufficient supplies, according to earnings announcements and survey data which point to a widening rift between the biggest store owners and the rest.

Walmart, Home Depot, Lowe’s and Target all reassured investors in recent days that they were starting their peak season with strong inventory levels.

Most of the “big box” chains commented that their size, deep vendor relationships and strong balance sheets were helping them gain market share, albeit at a cost to profit margins. But smaller brands painted a more challenging picture of inventories not recovering to pre-pandemic levels.
