 by the Code. Contributions can be made on a tax-deferred (pre-tax) basis, after-tax basis or to a Roth 401(k) on an after-tax basis, or a combination thereof through payroll withholdings. Participants may also rollover benefit payments from certain pension plans sponsored by the Company and other qualified plans into the Plan. Active participants may change the percentage of their contributions. First time eligible employees (newly hired, rehired, and certain transfers) are automatically enrolled into the Plan approximately 45 days after the date of hire, rehire, or transfer unless an alternative election is made. Contributions for those automatically enrolled in the Plan increase by one percent each year up to a maximum percentage specified by the Plan sponsor and relate to pre-tax and Roth 401(k) contributions only.

For employees hired before April 1, 2016, the Company’s matching contributions are generally as follows:

| Employee Contribution             |     | Company 
 Match   |     |   |
| First 2% of eligible compensation |     |         | 100 | % |
| Next 2% of eligible compensation  |     |         |  50 | % |
| Next 4% of eligible compensation  |     |         |  25 | % |
| Contributions over 8%             |     |         |   — |   |

Certain employees hired or rehired between July 1, 2008 and April 1, 2016, and who meet the applicable Plan requirements, are also eligible to receive an additional employer contribution known as a Retirement Account Contribution ("RAC"). The RAC contribution is generally made annually in the first quarter of the following year. Generally, participants must be employed by the Company on the last day of the plan year to be eligible to receive the RAC contribution. For the year ended December 31, 2024, the Company made a $51.6 million RAC contribution which was remitted to the Plan in March 2025. The amount is generally determined as a percentage of eligible compensation in accordance with the following table:

| Participant’s Age as of December 31, 2016 |     | Percentage of 
 Compensation  |   |   |
|:------------------------------------------|:----|:--------------|--:|:--|
| Under 35                                  |     |               | 3 | % |
| 35 – 49                                   |     |               | 4 | % |
| 50 or older                               |     |               | 5
