Introduction

Section 01

A letter from our CEO

Oscar was founded in 2012 as the first health insurance company built around a full stack technology

platform and a relentless focus on serving our members. Eleven years later, we are still motivated by the same mission: to make a healthier life accessible and affordable for all.

Consumers deserve better than the current, broken system. Zip codes determine health outcomes more often than genetic codes, and members are seen as numbers on a spreadsheet or diseases and diagnoses. Every individual deserves access to high- quality healthcare - no matter who they are.

Health equity is an essential part of our operating model. Oscar is at the forefront of providing tech-enabled, consumer- centric care. We use our technology to drive individualized care for our members, including many individuals who have been historically underserved or overlooked.

Oscar is powered by a group of people with unique backgrounds, experiences, and talents they bring to work every day - all working to change healthcare for the better. As someone who has long sought a path to make healthcare accessible and affordable for all Americans, I am more optimistic than ever that we can address this seemingly intractable problem.

Transparency, accountability, and continuous improvement are core to Oscar's ethos. In our second Impact Report we highlight where we apply these practices to our business

• including how we support our members, employees, and communities.

Introduction

What we stand for

At Oscar, we make a healthier life accessible and affordable for all.

Oscar is the first health insurance company built around a full stack technology platform and a relentless focus on member experience. We started Oscar in 2012 to create the kind of health insurance company we would want for ourselves - one that behaves like a doctor in the family.

Every American deserves access to affordable, high-quality healthcare that fits their life - from families seeking coverage that works for toddlers and their busy parents, to adults with chronic conditions who know their care providers by their first names, to small businesses choosing a benefits package - and everyone in between. We have built a scaled insurance business, powered by our own differentiated cloud-native technology platform, that enables us to earn our members' trust, leverage the power of personalized data, and help our members find quality care they can afford.

Section 01

Empowering our Members & Communities

Oscar aims to meet people where they are, no matter who they are. We work diligently to create a level of accessibility to match every other part of our members' lives. By leveraging

technology, engagement, and empathy, we can help to address the systemic barriers in healthcare that have made accessing quality care unattainable for many individuals.

Culturally Competent Care (CCC) takes these systemic barriers into account, delivering quality care to anyone and everyone with diverse values, beliefs, and behaviors. We launched Oscar's Culturally Competent Care Program in 2021, and our program has evolved from a pilot stage to supporting numerous CCC-focused workstreams with new partnerships and collaborations.

Today, we seek to ingrain cultural competency in everything we do, as we work to make care more affordable, accessible, and engaging for all members. We have seen our efforts resonate with the more than one million members we have the privilege to serve: our NPS increased to a record high of 60 in 2023.

Oscar"is working to retool healthcare experiences in a system that has failed so many. We believe in making the individual market the market for everyone, including the most vulnerable and overlooked populations. We know healthcare isn't one-size-fits-all, and we are focused on addressing the unique needs of the communities we serve. We work every day to bring our members the high-touch, personalized, seamless care they deserve.
