Forward-Looking Statements DISCLAIMERS Cautionary Note Regarding Forward-Looking Statements This presentation and related oral statements, including during any question and answer portion of the presentation, contain forward-looking statements about LifeStance Health Group, Inc. and its subsidiaries (“LifeStance”) and the industry in which LifeStance operates, including statements regarding: full-year and third quarter guidance and management’s related assumptions; the Company's financial position; business plans and objectives; our share repurchase authorization and repurchases thereunder; including planned capital allocation; and potential for disciplined acquisitions; operating results; working capital and liquidity; and other statements contained in this presentation that are not historical facts. These statements are subject to known and unknown uncertainties and contingencies outside of LifeStance's control and which are largely based on our current expectations and projections about future events and financial trends that we believe may affect LifeStance's financial condition, results of operations, business strategy, and prospects. LifeStance's actual results, events, or circumstances may differ materially from these statements. Forward-looking statements include all statements that are not historical facts. Words such as “anticipate,” “believe,” “envision,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “target,” “potential,” “will,” “would,” “could,” “should,” “continue,” “contemplate” and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements are subject to a number of risks, uncertainties, factors and assumptions, including, among other things: if reimbursement rates paid by third-party payors are reduced or if third-party payors otherwise restrain our ability to obtain or deliver care to patients, our business could be materially harmed; we may not grow at the rates we historically have achieved or at all, even if our key metrics may imply future growth, including if we are unable to successfully execute on our growth initiatives and business strategies; if we fail to manage our growth effectively, our expenses could increase more than expected, our revenue may not increase proportionally or at all, and we may be unable to execute on our business strategy; our ability to recruit new clinicians and retain existing clinicians; we conduct business in a heavily regulated industry and if we fail to comply with these laws and government regulations, we could incur penalties or be required to make significant changes to our operations or experience adverse publicity, which could have a material adverse effect on our business, results of operations and financial condition; we are dependent on our relationships with supported practices, which we do not own, to provide health care services, and our business would be harmed if those relationships were disrupted or if our arrangements with these entities became subject to legal challenges; we operate in a competitive industry, and if we are not able to compete effectively, our business and financial performance would be harmed; the impact on us of healthcare reform legislation and other changes in the healthcare industry and in healthcare spending is currently unknown, but may harm our business; if our or our vendors' security measures fail or are breached and unauthorized access to our employees', patients' or partners' data is obtained, our systems may be perceived as insecure, we may incur significant liabilities, including through private litigation or regulatory action, our reputation may be harmed, and we could lose patients and partners; our business depends on our ability to effectively invest in, implement improvements to and properly maintain the uninterrupted operation and data integrity of our information technology and other business systems; our existing indebtedness could adversely affect our business and growth prospects; and the other factors set forth in our filings with the Securities and Exchange Commission. The forward-looking statements, together with statements relating to our past performance, should not be regarded as a reliable indicator of our future performance. We undertake no obligation to update any forward-looking statements made in this presentation to reflect events or circumstances after the date of this presentation or to reflect new information or the occurrence of unanticipated events, except as may be required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future mergers, dispositions, joint ventures, or investments. Use of Non-GAAP Financial Measures In addition to financial measures presented in accordance with U.S. generally accepted accounting principles (“GAAP”), this presentation includes certain non-GAAP financial measures, including Center Margin, Adjusted EBITDA, and Adjusted EBITDA Margin. These non-GAAP measures are in addition to, and not a substitute for, or superior to, measures of financial performance prepared in accordance with U.S. GAAP. The non-GAAP financial measures used by LifeStance may differ from the non-GAAP financial measures used by other companies. A reconciliation of these measures to the most directly comparable U.S. GAAP measure is included in the Appendix to these slides or as otherwise described in these slides. Market and Industry Data This presentation also contains information regarding our market and industry that is derived from third-party research and publications. This information involves a number of assumptions and limitations.

Amounts are unaudited.   (1) - Primarily includes capital markets advisory, consulting, accounting and legal expenses related to the underwritten public offering of shares of our common stock by certain selling stockholders completed in the first and second quarters of 2026. (2) - Litigation costs, net of insurance recoveries, include only those costs which are considered non-recurring and outside of the ordinary course of business based on the following considerations, which we assess regularly: (i) the frequency of similar cases that have been brought to date, or are expected to be brought within two years, (ii) the complexity of the case (e.g., complex class action litigation), (iii) the nature of the remedy(ies) sought, including the size of any monetary damages sought, (iv) the counterparty involved, and (v) our overall litigation strategy. During each of the three and six months ended June 30, 2026 and 2025, litigation costs included cash expenses related to certain litigation matters, including a privacy class action litigation, and for the three and six months ended June 30, 2025, a compensation model class action litigation. (3) - Strategic initiatives consist of expenses directly related to evaluating and implementing a critical enterprise-wide scalable electronic health resources system in connection with our significant expansion. Strategic initiatives represents costs, such as third-party consulting costs and one-time costs, that are not part of our ongoing operations related to this enterprise-wide system. We considered the frequency and scale of this enterprise upgrade when determining that the expenses were not normal, recurring operating expenses. (4) - Real estate optimization and restructuring charges consist of cash expenses and non-cash charges related to our real estate optimization initiative, which included certain asset impairment and disposal costs, certain gains and losses related to early lease terminations, and exit and disposal costs related to our real estate optimization initiative to consolidate our physical footprint during 2023. As the decision to close these centers was part of a significant strategic project driven by a historic shift in behavior, the magnitude of center closures was greater than what would be expected as part of ordinary business operations and did not constitute normal recurring operating activities. During the three and six months ended June 30, 2026 and 2025, real estate optimization and restructuring charges consisted of certain gains and losses related to early lease terminations of previously abandoned real estate leases in 2023. (5) - Represents amortization of capitalized implementation costs related to cloud-based software arrangements that are included within general and administrative expenses included in our unaudited consolidated statements of operations and comprehensive income (loss).

We believe that FCF is a useful indicator of liquidity that provides information to management and investors about the amount of cash generated from our operations that, after investments in property and equipment, can be used for future growth. FCF is presented for supplemental informational purposes only and has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by (used in) operating activities. It is important to note that other companies, including companies in our industry, may not use this metric, may calculate metrics differently, or may use other financial measures to evaluate their liquidity, all of which could reduce the usefulness of this non-GAAP metrics as a comparative measure. The above table presents a reconciliation of net cash provided by (used in) operating activities to FCF, the most directly comparable financial measure calculated in accordance with GAAP.
