Axcelis Technologies Inc. (ACLS) shares tumbled 7.34% in after-hours trading on Monday, following the company's weaker-than-expected revenue guidance for the first quarter of 2025. The semiconductor equipment maker expects revenue of around $185 million for the current quarter, falling significantly short of analysts' consensus estimate of $221.59 million.

While Axcelis reported solid financial execution in 2024, the disappointing revenue outlook for Q1 2025 appears to have rattled investors. The company's CFO Jamie Coogan acknowledged the revenue miss but expressed optimism about their long-term prospects, stating "We are pleased with our financial execution in 2024 and remain focused on capitalizing on the secular growth opportunities in our industry."

Analysts and investors will closely monitor Axcelis' performance in the coming quarters, as the semiconductor industry faces ongoing challenges and uncertainties. The stock's after-hours plunge reflects concerns over the company's near-term revenue trajectory and its ability to meet market expectations.
