B2Gold's stock experienced a significant pre-market plunge of 9.48% on Thursday, reflecting a sharp downturn for the gold producer.

The decline follows the company's release of its fourth-quarter financial results, which revealed both earnings and revenue fell short of analyst consensus estimates. B2Gold reported adjusted earnings per share of $0.11, missing expectations that ranged from $0.18 to $0.21, while quarterly sales of $1.054 billion also came in below forecasts between $1.102 billion and $1.172 billion.

Additionally, the company's 2026 guidance signaled a potential production dip and higher costs, with consolidated all-in sustaining costs expected to rise significantly. Despite showing considerable year-over-year growth in both earnings and revenue metrics, the failure to meet market projections and the concerning outlook for the coming year likely drove the negative investor sentiment.
