Item 5.07 Submission of Matters to a Vote of Security Holders

On April 27, 2022, Oak Street Health, Inc. (the “Company”) held its 2022 Annual Meeting of Stockholders. Set forth below are the final voting results for each proposal submitted to a vote of the stockholders at the meeting.

Proposal No. 1: Election of directors.

The Company’s stockholders elected the following nominees for director to serve as Class II directors for a term expiring at the Company’s 2025 Annual Meeting of Stockholders and until their successors shall have been duly elected and qualified.

Proposal No. 2: Proposal to ratify of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022.

The appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022 was ratified by the Company’s stockholders.

Proposal No. 3: Proposal to recommend, by an advisory vote, the frequency of future advisory votes on executive compensation.

The Company’s stockholders recommended, by an advisory vote, to hold future advisory votes on the Company’s executive compensation (“Say-on-Pay”) every year.

Given the stockholders’ non-binding recommendation to hold the Say-on-Pay vote every year, on April 27, 2022 the Company’s board of directors considered the outcome of this advisory vote and determined that future Say-on-Pay votes will be conducted every year. The Company’s board of directors will re-evaluate this determination after the next stockholder advisory vote on the frequency of Say-on-Pay Votes (which will be at the Company’s 2028 Annual Meeting of Stockholders unless presented earlier).
