Axcelis Technologies (ACLS): Assessing Valuation After Third Quarter Revenue and Earnings Decline

Axcelis Technologies (ACLS) just released its third quarter results, and both revenue and net income have dropped compared to last year. The company also shared its guidance for the next quarter, highlighting ongoing challenges.

See our latest analysis for Axcelis Technologies.

The latest results come after a year of lumpy share price action for Axcelis Technologies, with the stock currently trading at $85.74. Despite recent quarterly dips in revenue and profit, short-term momentum has picked up, highlighted by a 22% year-to-date share price return. However, the one-year total shareholder return remains just under 1%. Over longer horizons, the three-year and five-year total returns of 11% and 230% reinforce that Axcelis still has long-term growth credentials. The pace of gains has clearly slowed this year.

Given weakening earnings and cautious forward guidance, the question becomes whether Axcelis Technologies is trading below its true value at these levels, or if the current price already reflects future challenges and opportunities.

Another View: What Do Market Multiples Tell Us?

Taking a step back from the fair value analysis, Axcelis Technologies trades with a price-to-earnings ratio of 19.6x. This is much lower than the semiconductor industry’s average of 35.4x and below its peer group average of 41.3x. However, compared to our calculated fair ratio of 15.1x, Axcelis looks somewhat expensive relative to its fundamentals.
