Margins Ease As Trailing Net Income Slips To US$120.2 Million

• On a trailing twelve month basis to Q4 2025, Axcelis generated US$839.0 million of revenue and US$120.2 million of net income, with net margin at 14.3% compared with 19.7% a year earlier.
• What stands out for the bearish narrative is that this margin step down lines up with their call for profit pressure. They assume margins fall from 14.3% to 8.4% over the next three years and earnings move from US$120.2 million to US$87.4 million.
  • Bears argue that lower non GAAP gross margins in the low to mid 40% range and a heavier memory mix could weigh on profitability, which is consistent with the recent margin compression shown in the trailing data.
  • Critics also point to China, which was 42% of 2025 revenue and is expected to be flat to slightly down, as a risk for both system and CS&I revenue, which fits with the idea that sustaining a 19.7% margin has already become harder.

Skeptics say the 14.3% margin and slowing earnings leave little room for error before profits undershoot expectations, and the full bear case for Axcelis lays out how that could play out over the next few years 🐻 Axcelis Technologies Bear Case.

P/E Of 40.5x Sits Below Industry And Peer Averages

• Axcelis trades on a trailing P/E of 40.5x at a share price of US$158.66, compared with a US Semiconductor industry average of 53.7x and a peer average of 63x, while the supplied DCF fair value is US$34.07.
• Supporters of the bullish narrative highlight that this lower P/E multiple versus industry and peers can look appealing, but there is tension with the data showing negative earnings growth over the past year and an 8.7% annual earnings decline projected over the next three years.
  • Bulls point to catalysts such as silicon carbide adoption and record CS&I revenue with double digit growth in 2025, yet the trailing figures still show net income falling from US$200.9 million to US$120.2 million and EPS sliding from US$6.17 to US$3.81.
  • The bullish view also leans on a higher future P/E multiple to reach an analyst price target of US$111.67, while the current share price of US$158.66 already stands well above both that target and the DCF fair value of US$34.07.

Bulls argue that Axcelis could earn a higher multiple if silicon carbide and memory demand play out as they expect, and the full bull case sets out how those drivers might justify paying up from here 🐂 Axcelis Technologies Bull Case.

Quarterly Revenue Stabilises After Earlier Step Down

• Within FY 2025, quarterly revenue moved from US$192.6 million in Q1 to US$238.3 million in Q4, after sitting at US$213.6 million in Q3, while trailing twelve month revenue declined from US$1.02b in Q4 2024 to US$839.0 million in Q4 2025.
• Analysts’ consensus narrative talks about a multi year opportunity as silicon carbide and power demand mature, yet the current dataset shows a more modest picture, with forecast revenue growth of 5.2% per year and earnings expected to decline about 8.7% per year despite revenue still being below the Q4 2024 level of US$252.4 million.
