June 12, 2025
Dear Fellow Shareholder,
Your vote at this year’s Annual Meeting of Stockholders on July 11, 2025 is extremely important. Ortelius Advisors, L.P. (“Ortelius”), which beneficially owns just 1% of Brookdale’s shares, is seeking to take control of your Board by replacing six of your highly qualified directors. Please protect the value of your investment TODAY by voting “FOR” ONLY the eight Brookdale nominees listed on the accompanying BLUE proxy card.
Brookdale’s substantially refreshed and experienced Board is overseeing the Company’s continued growth and transformation, with a strategy focused on five key initiatives to drive shareholder value:
Improving operating Optimizing our real Reinvesting capital Reducing our Investing in performance to drive estate portfolio to into our communities, leverage to our residents, higher occupancy, focus management’s using a portion of maintain financial associates, improve rates, and efforts on assets that asset sale proceeds flexibility and and culture generate robust can yield the greatest and improving cash resilience cash flow value for shareholders flow from operations

Increased 2025 Adjusted EBITDA1 midpoint Reduced community portfolio from more guidance by $7.5M than 1,000 in 2017 to less than 600 by year- end 2025
The Board is committed to acting as an agent of change, informed by shareholder feedback, as illustrated by its decision to begin an executive search process in late 2024 and transition Brookdale’s former CEO in April 2025.
Ortelius’ claims are not reflective of the progress Brookdale has made or the realities of the senior living industry and its unnecessary campaign risks significant value destruction. We believe Ortelius’ slate lacks the diversified skillset relevant to Brookdale’s strategy and its attempts to seize control of Brookdale’s Board will undermine our progress and impair our ability to identify a new CEO.
Your vote “FOR” ONLY the eight Company nominees listed on the accompanying BLUE proxy card ensures that all Brookdale shareholders’ best interests will continue to be served. Please simply disregard any white proxy card you may receive from Ortelius.

This communication mentions the financial measures Adjusted EBITDA and Adjusted EBITDA after cash financing lease payments, which are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). Reference to these non-GAAP financial measures are intended to aid investors in better understanding the factors and trends affecting the Company’s performance and liquidity. However, investors should not consider this non-GAAP financial measure as a substitute for financial measures determined in accordance with GAAP, including net income (loss) or income (loss) from operations.
Reconciliation of the non-GAAP financial measures included in the 2025 full-year annual guidance to the most comparable GAAP financial measures are not available without unreasonable effort due to the inherent difficulty in forecasting the timing or amounts of items required to reconcile Adjusted EBITDA from the Company’s net income (loss), including but not limited to (a) benefit/provision for income taxes, (b) non-operating income/expense items, (c) depreciation and amortization, and (d) income/expense associated with non-cash, non-operational, transactional, legal, cost reduction, or organizational restructuring items. Variability in the timing or amounts of items required to reconcile the measure may have a significant impact on the Company’s net income (loss).
Adjusted EBITDA
Adjusted EBITDA is a non-GAAP performance measure that the Company defines as net income (loss) excluding: benefit/provision for income taxes, non-operating income/ expense items, and depreciation and amortization; and further adjusted to exclude income/ expense associated with non-cash, non-operational, transactional, legal, cost reduction, or organizational restructuring items that management does not consider as part of the Company’s underlying core operating performance and that management believes impact the comparability of performance between periods.
The Company believes that presentation of Adjusted EBITDA as a performance measure is useful to investors because (i) it is one of the metrics used by the Company’s management for budgeting and other planning purposes, to review the Company’s historic and prospective core operating performance, and to make day-to-day operating decisions; (ii) it provides an assessment of operational factors that management can impact in the short-term, namely revenues and the controllable cost structure of the organization, by eliminating items related to the Company’s financing and capital structure and other items that management does not consider as part of the Company’s underlying core operating performance and that management believes impact the comparability of performance between periods; (iii) the Company believes that this measure is used by research analysts and investors to evaluate the Company’s operating results and to value companies in its industry; and (iv) the Company uses the measure for components of executive compensation.
