Your benefits, your choices: Annual enrollment is November 2 - 19.
Welcome to annual enrollment
At Diamond Infrastructure Solutions, we're committed to providing benefits that support your health, wellbeing and financial security. As Diamond Infrastructure Solutions launches as a standalone company, we're focused on creating a benefits experience designed to make it easier to access care, use your benefits and get support when you need it.
For 2027, you’ll have access to a comprehensive benefits package that provides strong coverage, valuable resources and tools to help you make informed decisions for yourself and your family. Many of the plans and programs available today will continue, helping provide a familiar and seamless experience during the transition.
You’ll also experience several updates being introduced for 2027, including new medical and prescription drug partners, expanded health care navigation support through Transcarent and new voluntary benefit options. These updates are designed to give you more choice, greater convenience and personalized support throughout your health care journey.
What's new for 2027
Take some time to review the updates below and the new resources available to you. We’ve got you covered every step of the way. With expanded support through Transcarent during this year’s annual enrollment, you’ll have access to personalized support to help you understand your medical plan options and choose the plan that best fits your needs. Over the coming months, we’ll ensure you have the information, tools and support you need to make informed decisions, ensure a smooth transition and get the most from your benefits.

The coverage you know, with new benefit partners
Your health benefits are an important part of the support the company provides to you and your family. In 2027, your medical plans will be administered by new benefit partners giving you more choice and broader access to care. The most important thing to know is that the coverage provided through those plans is not changing, and they remain company-sponsored plans. What is changing are the companies that administer those benefits on the behalf of Diamond Infrastructure Solutions.
Important note on eligibility
As a Diamond Infrastructure Solutions employee, you’ll continue to have access to a comprehensive benefits package that closely aligns with the coverage and programs you previously had, including the updates for 2027. However, please keep in mind the BCN HMO in Michigan will not be available to Diamond Infrastructure Solutions employees for 2027.
You will also move to a new 401(k) retirement savings plan effective January 1, 2027. This plan will be managed through LifeSight by WTW with Transamerica as the record keeper. No action is required during annual enrollment related to this transition but please keep in mind the Dow Employees' Savings Plan will not be available to Diamond Infrastructure Solutions employees for 2027. Watch for more details about the transition later this year.

What happens if you don’t enroll

- Your spouse/domestic partner will lose medical coverage. You must complete the annual spouse/domestic partner verification each year, even if you don’t change your coverage. This is required for any spouse/domestic partner, including those employed by Diamond Infrastructure Solutions. Any references to Dow as part of this verification process also apply to Diamond Infrastructure Solutions. Learn more in the benefits guide.
- You will not have Flexible Spending Account contributions in 2027.
