Methanex (MEOH) shares experienced a pre-market plunge of 10.43% on Friday, extending significant losses from the previous trading session.

The sharp decline was driven by the company's disappointing fourth-quarter financial results. Methanex reported an adjusted loss of $0.14 per diluted share, a dramatic swing from earnings of $1.24 per share in the same period a year earlier. This result fell far short of the analyst consensus estimate, which had anticipated earnings of $0.66 per share.

Furthermore, while quarterly revenue of $968.8 million showed a modest year-over-year increase, it also missed analyst expectations of approximately $1.02 billion. The unexpected swing to a loss and the substantial deviation from both earnings and revenue forecasts were the primary catalysts for the negative investor sentiment driving the stock's decline.
