Cytokinetics disclaims any intent or obligation to update these forward-looking statements and claims the protection of the Act's Safe Harbor for forward-looking statements. Examples of such statements include, but are not limited to, statements related Cytokinetics’ research and development and commercial readiness activities, including the initiation, conduct, design, enrollment, progress, continuation, completion, timing and results of clinical trials (including, but not limited to, SEQUOIA-HCM, MAPLE-HCM, and ACACIA-HCM), projections regarding growing prevalence, low survival rates and market opportunity in heart failure, hypertrophic cardiomyopathy (HCM) or heart failure with preserved ejection fraction (HFpEF); projections regarding the size of the addressable patient population for aficamten, omecamtiv mecarbil, or CK-586; the Cytokinetics’ commercial readiness for aficamten or omecamtiv mecarbil; the likelihood of approval and timing for regulatory approval of aficamten, omecamtiv mecarbil or any of our other drug candidates; the submission of a new drug application (NDA) to the FDA for aficamten in 2025, if ever; the timing of any potential commercial launch of our product candidates, if approved; commercial opportunities for our product candidates; the potential for aficamten to be first in line therapy for HCM; the potential REMS program for aficamten or any other differentiation from other therapies for HCM; Cytokinetics’ cash runway, future cash balances and estimated cash expenditures; interactions with the FDA; the properties, potential benefits and commercial potential of aficamten, omecamtiv mecarbil, CK-586 and Cytokinetics’ other drug candidates. Such statements are based on management's current expectations; but actual results may differ materially due to various risks and uncertainties, including, but not limited to, potential difficulties or delays in the development, testing, regulatory approvals for trial commencement, progression or product sale or manufacturing, or production of Cytokinetics’ drug candidates that could slow or prevent clinical development or product approval, including risks that current and past results of clinical trials or preclinical studies may not be indicative of future clinical trial results, patient enrollment for or conduct of clinical trials may be difficult or delayed, Cytokinetics’ drug candidates may have adverse side effects or inadequate therapeutic efficacy, the FDA or foreign regulatory agencies may delay or limit Cytokinetics’ ability to conduct clinical trials, and Cytokinetics may be unable to obtain or maintain patent or trade secret protection for its intellectual property; Cytokinetics may incur unanticipated research, development and other costs or be unable to obtain financing necessary to conduct development of its products; standards of care may change, rendering Cytokinetics’ drug candidates obsolete; and competitive products or alternative therapies may be developed by others for the treatment of indications Cytokinetics’ drug candidates and potential drug candidates may target. These forward-looking statements speak only as of the date they are made, and Cytokinetics undertakes no obligation to subsequently update any such statement, except as required by law. For further information regarding these and other risks related to Cytokinetics’ business, investors should consult Cytokinetics’ filings with the Securities and Exchange Commission (the “SEC”).

Patients Are Our North Star: Significant Impact of HCM The most commonly reported impacts of HCM symptoms on patients’ lives included limitations to physical activities (78%), emotional impacts, including feeling anxious or depressed (78%), and impacts on work (63%). My life was always unraveling, and after a while you get sick of being sick and weak. I could not even hold my husband’s hand and walk on the boardwalk, because I could not keep up with him. – HCM Patient Patients make their world smaller and don’t realize how symptomatic they have been until they feel well. – HCM Treater Zaiser E, Sehnert AJ, Duenas A, Saberi S, Brookes E, Reaney M.

Cardiac Myosin Inhibitors are Entering Treatment Guidelines
CMIs Have Transformed Patients’ Lives Selected example for illustration There was an incredible moment in clinic yesterday when I was able to tell a patient that her disease appeared to be “reversing”. This is the first time in my life I have used those words. Cardiac myosin inhibitors for hypertrophic cardiomyopathy are game changing. – Dr. Euan Ashley, Stanford
However, Opportunities Exist Key Benefits First non-interventional way to address underlying cause of oHCM Strong efficacy with few tolerability issues Few, if any, long-term concerns Key Challenges Burden of required monitoring/echo frequency Concerns about drug-drug interactions Down titration challenges Lack of treatment access/coverage for some Lack of established office protocols Sources: CMI Prescribing Process Research n=45 cardiologists, office staff and patients: Clearview, Echocardiogram Landscape Assessment n=25 cardiologists and payers; Putnam Associates, HCM Disease Treatment and Impact Study n=30 cardiologist; Hawk Partners, HCM HCP Emotive Insights n=24 cardiologists; BrandTrust While CMIs offer strong efficacy, there are barriers to more widespread use It’s revolutionary in my opinion With myosin inhibitors, you’re actually going to the problem of these HCM patients directly and treating the underlying cause of disease. It makes sense intuitively and mechanistically. I just wish it wasn’t so burdensome. – Academic cardiologist

Q&A
Closing Remarks Robert Blum President & CEO
Key Takeaways Cytokinetics is building a specialty cardiology franchise, led by aficamten, to address patient populations of high unmet medical need. Topline Results from SEQUOIA-HCM Expected by EOY Long-Term Data Support Safety and Efficacy of Aficamten Commercial Readiness Advancing CK-586 Aficamten is progressing in a broad development program, with topline results from SEQUOIA-HCM expected by EOY. Baseline characteristics reflect a population with substantial deficit in exercise capacity & significant symptom burden despite background therapy. New long-term data from FOREST-HCM show treatment with aficamten results in sustained improvements in clinical efficacy endpoints and no treatment interruptions for low ejection fraction. Cytokinetics is engaging in ongoing commercial readiness activities, with market research revealing a symptomatic patient population in need of treatment with a potential next-in-class CMI. The company is advancing CK-586, a second cardiac myosin inhibitor for the potential treatment of patients with HFpEF. Aficamten and CK-586 are investigational drugs and are not approved by any regulatory agency. Their safety and efficacy have not been established.
