Shares of Iamgold (IAG) plummeted 5.57% in trading on Tuesday, following the release of the company's mixed first-quarter earnings report. The significant drop came as the gold miner reported revenue that fell short of analysts' expectations, overshadowing a slight beat on earnings per share.

Iamgold announced quarterly revenue of $477.1 million, missing the FactSet consensus estimate of $500.9 million by a considerable 4.75%. This shortfall likely triggered the sharp sell-off in the stock. However, the company did report a positive surprise on the bottom line, with adjusted earnings per share coming in at $0.10, surpassing the analyst consensus estimate of $0.09 by 11.11%.

Despite the earnings beat, investors appeared to focus on the revenue miss, reflecting concerns about the company's near-term prospects. The mixed results, with strong year-over-year sales growth but a slight earnings decline, suggest that Iamgold may be facing cost pressures or operational challenges that are impacting its profitability. As the market continues to digest this earnings report, all eyes will be on Iamgold's management for guidance on how they plan to address the revenue shortfall in the coming quarters.
