FormFactor (NASDAQ: FORM) stock is surging 6.61% in pre-market trading on Thursday, following the release of its impressive first-quarter 2025 financial results and optimistic second-quarter guidance. The semiconductor test equipment manufacturer's performance significantly exceeded analyst expectations, demonstrating resilience in a challenging market environment.

The company reported adjusted earnings per share (EPS) of $0.23 for Q1, outperforming the analyst consensus estimate of $0.19 by 21.05%. This represents a substantial improvement from the $0.18 per share reported in the same period last year. Revenue for the quarter also surpassed expectations, reaching $171.36 million versus the analyst estimate of $169.98 million, translating to a 1.56% year-over-year increase. FormFactor's adjusted net income of $18 million also beat the IBES estimate of $14.8 million.

Adding to the positive sentiment, FormFactor provided an upbeat outlook for the second quarter, forecasting revenue of $190 million, plus or minus $5 million. This guidance suggests continued growth and confidence in the company's near-term prospects. CEO Mike Slessor commented on the results, stating, "As expected, FormFactor reported sequentially lower first-quarter revenue and profitability due to anticipated reductions in demand for both DRAM probe cards and Systems." Despite these challenges, the strong performance and optimistic guidance have clearly resonated with investors, driving the significant stock price increase observed in pre-market trading.
