There is no waiting period. You can enroll in the Plan at any time.

When you are a rehire, you may enroll at any time using your prior Fidelity log in credentials to make your deferral election. Your prior deferral election will carry forward if (1) you are rehired within the same calendar year or (2) you end employment after October 18 and are rehired within 75 days. Otherwise, your prior election will not carry forward.

If you have not enrolled in the Plan within 45 days from your date of hire, you will be automatically enrolled in the Plan at a contribution rate of 5% of your pretax eligible earnings. Your contributions will be invested in a T. Rowe Price Retirement Trust Class F based on a target retirement date, assuming retirement at age 65 as determined by the Plan Sponsor. However, we encourage you to take an active role in the Plan and to choose a contribution rate and investment options that are appropriate for you. If you do not wish to contribute to the Plan, you must change your contribution rate to 0% within the first 45 days from your date of hire.

Enroll online at any time, or by calling the Fidelity Retirement Benefits Line at 1-800-890-4015.

If you elect a contribution % before you are auto enrolled (45 days after eligibility) or you make a change in the future, salary deductions will generally begin within 1-2 pay periods after we receive your contribution election, or as soon as administratively possible.

Through automatic payroll deduction, you can contribute between 1% and 80% of your eligible pay on a pretax and/or Roth 401(k) basis, up to the annual IRS dollar limit.

In addition, you can automatically increase your retirement savings plan contributions each year through the Annual Increase Program. You can sign up by logging on to Fidelity NetBenefits^® at www.netbenefits.com and click on "Contribution Amount" or by calling the Fidelity Retirement Benefits Line at 1-800-890-4015. You can request to change your contribution amount virtually any time by logging on to Fidelity NetBenefits^® at www.netbenefits.com or by calling the Fidelity Retirement Benefits Line at 1-800-890-4015.

A Roth contribution to your retirement savings plan allows you to make after-tax contributions and take any associated earnings completely tax free at retirement - as long as the distribution is a qualified one. A qualified distribution, in this case, is one that is taken at least five tax years after your first Roth 401(k) contribution and after you have attained age 59½, or become disabled or die. Starting in 2026, if your FICA wages from the prior calendar year with your current employer exceeded $150,000, any age 50 catch-up contributions to the Plan must be made as Roth contributions. If your FICA wages were $150,000 or less, you can designate your catch-up contribution to be pretax or Roth.

This plan provision will allow you to convert your eligible assets to a designated Roth account within the plan. Converting to a Roth can be beneficial if you expect your tax rate to increase in the future, because you pay taxes now on the money you convert.

If you have reached age 50 or will reach 50 during the calendar year January 1 – December 31 you can make a larger contribution to your workplace savings plan each year than your younger coworkers can. For instance, your eligible “catch-up contribution” for 2026 is $8,000, bringing your total allowable contribution to $32,500 in 2026. Catch-up contributions happen automatically. If you do not want to contribute the additional catch-up contribution amount you must log on to www.netbenefits.com and change your deferral percentage to zero once you reach the annual amount you wish to contribute. If you set your contribution to zero, you will need to reelect your contribution to begin contributing again.

Starting in 2026, if your FICA wages from the prior calendar year with your current employer exceeded $150,000, any age 50 catch-up contributions to the Plan must be made as Roth contributions. If your FICA wages were $150,000 or less, you can designate your catch-up contribution to be pretax or Roth.

Starting in 2025, the SECURE 2.0 Act increases the limit for you if you have attained age 60, 61, 62, or 63 in a given calendar year. The limit for 2026 is $11,250.

The IRS contribution limit for 2026 is $24,500.

The Company helps your retirement savings grow by matching your pretax and Roth 401(k) contributions. The Company will match 100% of the first 3% of eligible compensation you contribute, and 50% of the next 2% of eligible compensation that you contribute to your Plan.

You are immediately 100% vested in your own contributions to the Plan, as well as 100% vested in any of the Company's matching contributions and any earnings on them.

To help you meet your investment goals, the Plan offers you a range of options. You can select a mix of investment options that best suits your goals, time horizon, and risk tolerance. The many investment options available through the Plan include conservative, moderately conservative, and aggressive funds. A complete description of the Plan’s investment options and their performance, as well as planning tools to help you choose an appropriate mix, are available online.

We encourage you to take an active role in the Hologic, Inc. Savings and Investment Plan and choose investment options that best suit your goals, time horizon, and risk tolerance. If you do not select specific investment options in the Plan, your contributions will be invested in the T. Rowe Price Retirement Trust Class F with the target retirement date closest to the year you might retire, based on your current age and assuming a retirement age of 65, at the direction of Hologic, Inc.

If no date of birth or an invalid date of birth is on file at Fidelity, your contributions may be invested in the T. Rowe Price Retirement 2015 Trust Class F. More information about the T. Rowe Price Retirement Trust Class F options can be found online.

Target Date Funds are an asset mix of stocks, bonds and other investments that automatically becomes more conservative as the fund approaches its target retirement date and beyond. Principal invested is not guaranteed.

Although your plan account is intended for the future, you may borrow from your account for any reason.

If you are a rehire with a current Hologic 401k loan, your loan will be transitioned back to payroll deductions upon rehire.

Withdrawals from the Plan are generally permitted when you terminate your employment, retire, reach age 59½, become permanently disabled, or have severe financial hardship as defined by your Plan.

When you leave the Company, you can withdraw contributions and any associated earnings or, if your vested account balance is greater than $1,000, you can leave contributions and any associated earnings in the Plan. After you leave the Company, if your vested account balance is equal to or less than $1,000, it will automatically be distributed to you.

You are permitted to roll over eligible pretax and Roth contributions from another 401(k) plan, 403(b) plan or a governmental 457(b) retirement plan account or eligible pretax contributions from conduit Individual Retirement Accounts (rollover IRAs) and certain non-conduit individual retirement accounts (traditional IRAs, Simplified Employee Pension plans, and "SIMPLE" IRA distributions made more than two years from the date you first participated in the SIMPLE IRA). A conduit IRA is one that contains only money rolled over from an employer-sponsored retirement plan that has not been mixed with regular IRA contributions.
