Subject: Option Care Health to Combine with Amedisys, Creating a Leading, Independent Platform for Home and Alternate Site Care

I’m very pleased to share exciting news with you. Moments ago, we announced an agreement to combine with Amedisys, a leading provider of healthcare in the home.

Option Care Health has always been guided by our mission to transform healthcare by providing innovative services that improve outcomes, reduce costs, and deliver hope and dignity for patients and their families. The pursuit of our mission has allowed us to become one of the leading providers of home infusion and alternate site infusion services in the nation. At the same time, we’ve consistently sought out opportunities to grow and transform to even better serve patients and communities. This combination with Amedisys will help us do just that, further advancing our mission.

Together, Option Care Health and Amedisys will offer patients and their families a more comprehensive care platform serving chronic, acute, and post-acute patient populations across a broad continuum from preventative care through end-of-life care. Based in Baton Rouge, Louisiana, Amedisys has a strong presence in hospital at home, home health, hospice, palliative, and high-acuity care services across the country. Combining forces enables us to expand beyond our existing home and alternate site infusion services. With the addition of Amedisys, we will become a leader in end-to-end home-based health solutions and will be well positioned to meet the growing demand for personalized alternate site care services.

An Exciting Future

Indeed, there is a lot to be excited about as a combined company. Upon taking a look at the trajectory of healthcare in the alternate site care space, it became clear that Amedisys complements Option Care Health and that this is the right time for us to join together. This is a transaction about growth, and together we will have a scaled national platform that will help us deliver even more benefits to patients and their families, providers, payers, and care teams. Additionally, our companies are expected to benefit from combined patient data sets, which will enhance opportunities to proactively identify interventions, increase patient engagement, enhance clinical protocols, and offer value-based care.

Importantly, Amedisys is also a great fit from a cultural perspective. Like us, their team is mission driven and passionate about delivering high-quality, affordable care to the patients we have the privilege to serve. Together, we will have a national clinician workforce of more than 16,500 professionals including but not limited to nursing professionals, pharmacists, pharmacy technicians, dieticians, physical, occupational, and speech therapists, social workers, and aides across 46 states, and will have 674 care centers across the U.S.

Upon completion of the transaction, I will lead the combined company, and Mike Shapiro will serve as CFO. We will remain headquartered in Bannockburn, Illinois, and will continue to maintain substantial operations in Amedisys’ corporate locations in Baton Rouge, Louisiana and Nashville, Tennessee. The combined company will have operations throughout the U.S. consistent with its local and community-based approach.

Next Steps

This announcement is an exciting step, but please keep in mind that today is only the first step. We expect the transaction to be completed in the second half of 2023 subject to approval by Option Care Health and Amedisys stockholders and other customary closing conditions, including receipt of applicable regulatory approvals. Until that time, Option Care Health and Amedisys will continue to operate as two independent businesses, and it remains business as usual for everyone. This afternoon we also announced strong results for the first quarter, which demonstrate the great momentum underway. It’s important that we keep up the good work.

For most of you, today’s announcement will not impact your day-to-day roles and responsibilities. It is important that we all remain focused on making a positive difference in people’s lives. In terms of bringing our operations together, we are focused on a successful and seamless transition for all our stakeholders. We will keep you informed as appropriate.

We understand that you may have questions about this announcement and what it means for our company and for you – attached is an FAQ, which we will also post on OCHO.

Thank you for all of your hard work and dedication to Option Care Health. It’s because of your efforts that we continue to transform healthcare and be at the forefront of our industry.

Sincerely,

John Rademacher

Option Care Health President and CEO
