Shares of Fortuna Silver Mines (FSM) soared 5.08% in after-hours trading on Wednesday, following the release of its third-quarter earnings report. The stock's positive reaction comes despite a mixed financial performance that saw earnings miss but revenue exceed analyst expectations.

Fortuna Silver Mines reported quarterly earnings of $0.17 per share, falling short of the analyst consensus estimate of $0.19 by 10.53%. However, this still represents a 6.25% increase compared to earnings of $0.16 per share from the same period last year. On the revenue front, the company posted quarterly sales of $251.400 million, surpassing the analyst consensus estimate of $246.200 million by 2.11%. It's worth noting that this figure reflects an 8.55% decrease from sales of $274.900 million in the same quarter of the previous year.

The stock's after-hours rally suggests that investors may be focusing on the revenue beat and year-over-year earnings growth, despite the earnings miss. It's possible that the market had lower expectations or that other factors, such as forward guidance or operational updates not mentioned in the provided news, could be influencing the positive sentiment. As trading resumes in the regular session, it will be interesting to see if this optimism persists or if the mixed results lead to a reassessment of the stock's valuation.
