The following are excerpts from the transcript of certain portions of the podcast relating to the proposed merger of Halo Merger Sub Corp. with and into Oak Street Health, Inc. (“Oak Street Health”) with Oak Street Health as the surviving corporation.

Allen Murray

Yeah, let's start with the big one Oak Street health. That's a $10 billion acquisition. It's very exciting. But it's a different business than you've been in in the past. So, tell us where that's taking you?

Karen Lynch

Yeah. So, you know, Ellen and Alan, if you just rewind back to December of 2021. You know, we were in the midst of a pandemic, I, you know, kind of took over earlier that year, and while we were dealing with vaccines, we're repositioning the company with our overall intent to really change the way consumers experience and engage with their health care system. So we laid out a really bold path of really doing an integrated offering. So extending into broader health services. And we said we were going to extend into primary care because primary care is the center of the connection of health care. The pandemic changed the way you know, people were interacting with the health care system. So we wanted to extend in the home. The health care system is changing dramatically. We are moving from a very much a transactional based health care system, where typically people call it fee for service to what we call value-based care. And that's really where primary care comes in. Oak Street is the leader in primary care serving underprivileged and serving Medicare Advantage members. And with that acquisition, plus you mentioned it earlier Allen, and plus the acquisition of Signify Health have the premier payer agnostic value-based care assets to support Medicare bar none in the country, and our goal will be to improve health, improve health outcomes, improve quality, improve access and convenience.

Allen Murray

Yeah, that's that really is fascinating. The one thing I want to follow up on you said payer agnostic. I mean, obviously, Aetna is a health care provider, health care payer, but you want to provide primary care to all comers.

Karen Lynch

That's correct. We, you know, some of our competitors, our primary customers in Oak Street and in Signify similar to what we do in our pharmacy benefits management company, similar to what we do we serve all customers in CVS retail, and our intent is to provide primary care for all customers focusing first on Medicare Advantage, because we think you know, that's the largest population, has the highest cost, has the most chronic conditions, we feel like we can have a huge impact on improving overall health outcomes in that population.

Ellen McGrit

Tell us a little bit about Signify. As I was preparing for this conversation, I spent more time than I expected to on their website, looking through their offerings, but also understanding how they interacted in vulnerable communities. And I was surprised at their focus, and that a big company would be interested in working with them in this way. Tell us a little bit about it.

Karen Lynch

People throughout the last two years have really changed the way they thought about health care delivery. And people want convenience that could be through digital connections, that could be through community-based assets, like an Oak Street, or can be in the home. And what Signify does, they're in 50 states, they go into the home, and they basically do assessments of your overall health, and then they reconnect you to the care that you need. So imagine sitting across the table and interacting with someone that can help you understand, you know, your blood pressure and talk more about it, they can actually open up a refrigerator door and see what's in there. You know, what kind of food are you eating, and you both know, food is really important, it's part of your overall health. And if you're not eating healthy, that's going to have an impact on your health.

And then they can redirect you. What's interesting about Signify Health is 30% of the people that they see either don't have a primary care physician, or have an assigned one that they're not using. Think about the possibility that we have to connect those patients into a primary care asset like Oak Street, or, you know, working with them with our pharmacists and doing medical reconciliations to make sure that their medicines are appropriate for the conditions that they're having. So again, you see the interplay. Signify an important home asset interplays with Oak Street quite nicely, and will intersect with the rest of CVS Health. So that we have that connected experience for the consumer. I'm really excited about the possibilities here. Now we have to close the transactions.

Allen Murray

Yeah, of course. Ellen, by the way, is far too young to be talking about Medicare, but I have my card. I'm ready to go. Do Oak Street Health and Signify replace my primary care physician, the statistic you gave was fascinating that many people my age don't have a primary care physician. But what if you do?

Karen Lynch

You know, it depends on what plans you pick, what primary care you have. So if you're in a Medicare Advantage plan, you may pick a product that has, Oak Street Health primary care available to you, or you keep your own. Love to share a story with you about Oak Street just to give you a sense for what that primary care experience looked like when we were going through the transaction. I had the opportunity to go visit one of the clinics, right down the street here in Woonsocket, Rhode Island. And what's fascinating is they obviously have transportation for those individuals that don't have a way to get to the doctor. They'll bring you to the clinic, but what the real sort of benefit that I saw was that it's more of not just the primary care, it's a community, there was a woman in there, she's lonely, she doesn't have anyone at home, she goes into the community center every single day. And at that point in time, she was making decorations for the community center. And then obviously, she's getting her care there. And it was just, you know, it's really what health care should be, in the community, easy access and improving her quality of care. And, you know, I talked to her for a little while, and she was just so excited about the people that she meets there and about how she's getting her follow up care. And it's just a different model. And it is a very, you know, and she's digitally connected to them as well. And it's just a way to have people to not only keep thinking about their health, but kind of that broader aspect of all parts of your well being and staying connected in the community.

Allen Murray

And how will the clinics relate to the stores? I mean, do you see them ultimately being located adjacent to the stores inside the stores? What's the connection?

Karen Lynch

Yeah, I think there's a couple of ways that we're thinking about it. You know, there are stores that we have today in that we have because they're in underserved communities, and there would be a pharmacy desert, or maybe a food desert. And we have those stores for those purposes. So those were our likely places where we may kind of reposition a store and put an Oak Street clinic in that particular store. That's one model. Another model is looking kind of broadly, where kind of where the population is that you know, meet the criteria, Medicare Advantage, dual eligibles, underserved communities, where Oak Street is today and then expanding out so that we kind of hit that population. That's how we're thinking about it so sometimes they could be in a store, sometimes they could be close to a store, sometimes they could be adjacent to a store. The way we're going to use our stores, you know, kind of those pharmacies and those minute clinics is to provide wraparound services, or sometimes when there's just a convenient get your vaccine, you don't really need to go to the clinic. And those are the types of things maybe some smaller urgent types of things that someone might need, we'll kind of use those stores as the wrap around to bring additional capacity to that Oak Street clinic.

Ellen McGrit

Where does mental and behavioral health fit into your vision?

Karen Lynch

It is front and center, it has to be part of the overall equation, we as a company, are very committed to connecting the mental health and the physical health, Oak Street has part of their services includes the behavioral health, I don't think you can think about health without including behavioral health. And when you're serving, you know, patients, whether they be in Medicare, whether they're, you know, a woman who's suffering from postpartum depression And I talk about this often, that women, you know, when they have babies, it's most joyful time of their life. At the same time, more and more women suffer from postpartum depression, your care plan should include that conversation and that discussion, and those access points for them. And I think, as you know, as kind of health care companies, we have to get better at doing those kinds of holistic care plan so that we're getting in front of it. So it's central to how we think about health, it's central to our platform for health. And it's central to the long-term strategy, this company and I think, for the U.S. health care system, it has to be integrated.
