Forward looking statements This presentation and other related material may contain a number of “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including statements regarding Karuna’s expectation about any or all of the following: (i) the timing, progress and results of preclinical studies and clinical trials for KarXT and other product candidates it may develop, including statements regarding the timing of initiation and completion of studies or trials and related preparatory work and the period during which the results of the trials will become available; (ii) Karuna’s research and development plans, including its plans to explore the therapeutic potential of KarXT in additional indications; (iii) Karuna’s plans to develop and commercialize KarXT, KAR-2618 and other product candidates; and (iv) the timing of and Karuna’s ability to submit for, obtain and maintain marketing approvals for its product candidates. Forward-looking statements can be identified by terms such as “could,” “expects,” “intends,” “may,” “plans,” “potential,” “should,” “will,” “would,” or similar expressions and the negative of those terms. Karuna has based these forward-looking statements largely on its current expectations and projections about future events and financial trends that it believes may affect its business, financial condition and results of operations. Although Karuna believes that such statements are based on reasonable assumptions, forward-looking statements are neither promises nor guarantees and they are necessarily subject to a high degree of uncertainty and risk. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond Karuna’s control, you should not rely on these forward-looking statements as predictions of future events. These risks and uncertainties include, among others: outcomes of Karuna’s planned and ongoing clinical trials and studies may not be favorable; one or more of Karuna’s product candidate programs may not proceed as planned for technical, scientific or commercial reasons; availability and timing of results from preclinical studies and clinical trials; uncertainty about regulatory approval to conduct clinical trials or to market products; uncertainties regarding intellectual property protection; risks relating to business interruptions resulting from the coronavirus (COVID-19) pandemic; and those risk and uncertainties described under the heading “Risk Factors” in Karuna’s Annual Report on Form 10-K for the year ended December 31, 2022, and filed with the Securities and Exchange Commission on February 23, 2023, and in any other subsequent filings made by Karuna with the U.S. Securities and Exchange Commission, which are available at www.sec.gov. Existing and prospective investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. Karuna disclaims any obligation or undertaking to update or revise any forward-looking statements contained in this presentation, other than to the extent required by law.

KarXT was generally well tolerated, consistent with prior EMERGENT trials Summary of safety and tolerability of safety population (KarXT n=125, placebo n=128) TEAE = treatment emergent adverse event, GERD = gastroesophageal reflux disease, EPS = extrapyramidal symptoms KarXT was generally well tolerated Overall discontinuation rate was 33% (37% KarXT vs. 29% placebo) Discontinuation rates related to TEAEs were similar between treatment arms (6% KarXT vs. 5% placebo) Overall TEAE rates for KarXT and placebo were 70% and 50%, respectively Only serious TEAE reported in the KarXT group related to GERD and deemed not to be related to study drug The most common KarXT TEAEs (>5%) were all mild to moderate in severity Common KarXT TEAEs (>5%) were nausea, dyspepsia, vomiting, constipation, headache, hypertension, diarrhea, and insomnia, with rates consistent with EMERGENT-2 Cholinergic TEAEs mostly occurred within the first two weeks of treatment and were generally transient in nature Rates of headache and insomnia were similar to placebo TEAEs of hypertension (6% KarXT vs. 2% placebo) did not lead to trial discontinuation Vital signs were consistent with prior trials of KarXT in schizophrenia Mean blood pressure change from baseline was similar between KarXT and placebo An increase in heart rate was associated with KarXT treatment and decreased in magnitude by the end of the trial No syncope observed Measures of weight gain, somnolence and EPS were similar between KarXT and placebo 15
