Kulicke & Soffa (NASDAQ: KLIC), a leading provider of semiconductor production equipment, experienced a 5.21% after-hours plunge in its stock price on Tuesday, despite posting better-than-expected sales in Q4 FY2024 and beating analysts' estimates for revenue and earnings.

The company's stock decline can be attributed to its Q1 FY2025 guidance, which fell short of Wall Street's expectations. Kulicke & Soffa projected revenue of $165 million at the midpoint, missing analysts' estimates of $173.5 million. Additionally, the company's adjusted EPS guidance for Q1 FY2025 of $0.19 at the midpoint was lower than analysts' forecasts of $0.30.

Despite the lower guidance, Kulicke & Soffa reported solid Q4 FY2024 results, with revenue of $166.1 million, beating analyst estimates of $165 million. The company's adjusted EPS of $0.37 also surpassed analysts' consensus estimates of $0.28. However, investors appear to be focused on the company's cautious outlook for the upcoming quarter, leading to the after-hours sell-off.
