Walmart's stock experienced a significant pre-market plunge of 5.39% on Thursday, following the release of its first-quarter financial results.

While the retail giant reported quarterly revenue that exceeded analyst expectations, investors reacted negatively to the company's decision to maintain its full-year earnings guidance, which remains below Wall Street's forecasts. Walmart's outlook for the second quarter also fell short of estimates, contributing to the sell-off.

The company highlighted that rising fuel costs are creating substantial headwinds, impacting operating income by approximately 250 basis points in the distribution and fulfillment operations. Walmart's CFO warned that if the current elevated cost environment persists, consumers could face higher retail prices in the coming months, reflecting the strained economic backdrop affecting American spending.
