Management Comments

• This transaction was made pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on December 11, 2025.
• Of the shares held after this sale on March 24, 2026, 83,480 were issuable on vesting of restricted stock units granted to the reporting person under the 2012 Equity Incentive Plan and are subject to forfeiture.

Industry Context

StockSavvy.ai notes that insider sales under Rule 10b5-1 plans are common and often pre-scheduled to allow executives to diversify holdings without concerns about insider trading allegations. The semiconductor equipment industry, in which Axcelis operates, is highly cyclical, and executives often use such plans to manage personal liquidity over long periods, irrespective of short-term market movements.

Stakeholder Impact

• Shareholders: The sale of a small percentage of the CEO's holdings under a 10b5-1 plan is generally not seen as a significant signal of management's view on future stock performance, especially given the remaining substantial beneficial ownership. The achievement of 2025 performance goals is positive for shareholder value.

Next Steps

• Future vesting of 83,480 restricted stock units under the 2012 Equity Incentive Plan.

Key Dates

Recommendation

The filing reports a routine insider sale by the CEO under a pre-established 10b5-1 plan, which is a common practice for executive liquidity and diversification. This transaction does not provide new material information about the company's operational performance or future prospects that would warrant a change in investment recommendation. The positive note about achieving 112.5% of 2025 performance goals for RSUs is a good sign, but the overall impact of this Form 4 is neutral.
