Sonoco Products' stock experienced a pre-market plunge of 5.71% on Wednesday, following negative investor reaction to the company's latest financial updates.

The packaging solutions company reduced its full-year guidance, citing higher input costs as a key factor. Sonoco now expects adjusted earnings at the low end of its previous guidance range of $5.80 to $6.20 per share, with projected sales between $7.25 billion and $7.75 billion for 2026.

Additionally, the company reported first-quarter sales of $1.68 billion, representing a 1.9% decline and falling short of analysts' expectations of $1.71 billion. These developments have prompted investor concern about the company's near-term profitability amid rising operational costs.
