 forfeit any employer matching contributions related to the distribution amount. Amounts forfeited will be used by the Company to reduce future employer matching contributions.

The Company contributes to the Plan through matching contributions and may contribute to the Plan through discretionary employer contributions. The Company matches 50% of the first 6% of each participant's eligible earnings contributed to the Plan. The Plan provides for annualized matching contributions, thereby allowing for true-ups to be made to ensure participants receive the maximum matching contributions irrespective of contribution timing. There were no discretionary employer contributions made for the Plan years ended December 31, 2024 and December 31, 2023.

The IRS limits the amount of pay that may be used to determine participants' discretionary contributions. The limits were $345,000 and $330,000 in 2024 and 2023, respectively. The IRS also limits the amount of all contributions that can be made for or by a participant to all Plans in a given year. The limits were the lesser of 100% of pay or $69,000 in 2024 and the lesser of 100% of pay or $66,000 in 2023.

Employee rollover contributions from other qualified retirement plans are permitted; such contributions are subject to the conditions and procedures set forth in the Plan.

#### Participant Accounts
Each participant's account is credited with that participant's contributions, allocations of the Company's matching contributions, discretionary employer contributions, if any, and Plan earnings and losses. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Terminated participants forfeit unvested Company contributions. Forfeitures are used to reduce future employer matching contributions.

#### Vesting

| Periods of Service            |     | Percentage |     |   |
| Less than 1 year              |     |            |   — | % |
| At least 1, less than 2 years |     |            |  33 | % |
| At least 2, less than 3 years |     |            |  67 | % |
| 3 or more years               |     |            | 100 | % |
