The global packaging company reported earnings per share (EPS) of $0.28 for the quarter, missing analysts' expectations of $0.65 per share, according to FactSet estimates.

Smurfit Westrock's pre-market stock price decline reflects investors' disappointment with the company's performance and their concerns about the potential impact on future profitability and growth prospects. Market participants will closely monitor the company's upcoming earnings call and financial disclosures for more insights into the challenges faced during the quarter and the management's strategies to address them.
