Watertown, Mass. (August 5, 2026) – Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of oral small molecule degrader medicines for immunological diseases, today reported financial results for the second quarter ended June 30, 2026, and provided business highlights and updates on its pipeline.

“Kymera is delivering in a pivotal period of execution, with multiple clinical-stage programs advancing, important data catalysts ahead, and growing conviction in the potential of oral degrader medicines to transform the standard of care for chronic, debilitating immunological diseases,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “The rapid completion of enrollment in our KT-621 BROADEN2 Phase 2b trial in atopic dermatitis nearly six months ahead of our original timeline is a powerful example of the immense interest from clinicians and patients in a once-daily oral therapy and excellent execution from the Kymera team. The accelerated timeline enables us to pull forward our expected topline readout to year-end 2026, positions us for an earlier than anticipated start to Phase 3 trials next year, and ultimately allows us to move faster for patients who are waiting for new options.”

Dr. Mainolfi continued, “We see the significant gaps that remain across the immunology treatment landscape, and we are hearing directly from clinicians, advocacy groups, patients and their families about the need for effective, safe, and convenient approaches. We remain focused on executing across our differentiated portfolio to address those needs. With KT-621 advancing in both AD and asthma, KT-579 progressing toward Phase 1 data and a planned patient proof-of-concept trial in lupus, and important progress across our partnered programs and early discovery engine, we are translating that urgency into action as we work to deliver a new generation of oral medicines.”

Business Highlights, Recent Developments and Upcoming Milestones

STAT6 Degrader Program

KT-621 is an investigational, first-in-class, once daily, oral degrader of STAT6, the specific transcription factor responsible for IL-4/IL-13 signaling and the central driver of Type 2 inflammation. KT-621 is

currently in Phase 2 clinical development in atopic dermatitis (AD) and asthma. KT-621 has the potential to transform treatment for more than 140 million patients around the world suffering from Type 2 diseases such as atopic dermatitis (AD), asthma, chronic obstructive pulmonary disease (COPD), eosinophilic esophagitis (EoE), chronic rhinosinusitis with nasal polyps (CRSwNP), chronic spontaneous urticaria (CSU), prurigo nodularis (PN), and bullous pemphigoid (BP), among others.

• In June 2026, the Company announced the completion of enrollment in the KT-621 BROADEN2 Phase 2b clinical trial in patients with moderate to severe atopic dermatitis nearly six months ahead of its original timeline. The earlier than expected completion of enrollment enabled the Company to accelerate its expected topline data readout by six months to year-end 2026, earlier than prior guidance to share data by mid-2027. Subject to discussions with regulators, the Company expects to initiate Phase 3 trials in AD by mid-2027.

• Enrollment is ongoing in the KT-621 BREADTH Phase 2b clinical trial in patients with moderate to severe eosinophilic asthma. The Company expects to report data in late 2027.

• In June 2026 at the Japanese Dermatological Association (JDA) Annual Meeting, the Company presented results from the KT-621 Phase 1 study in healthy Japanese adults designed to support the enrollment of patients in Japan in global KT-621 studies. KT-621 demonstrated a favorable PK profile, rapid and sustained STAT6 degradation in blood, with median STAT6 degradation of ≥98% at both dose levels, and a favorable safety and tolerability profile. These results are consistent with those observed in non-Japanese healthy adults and atopic dermatitis patients.

• The Company presented data from the KT-621 Phase 1 clinical trials across leading dermatology and respiratory forums, including a late-breaking oral presentation at the Society for I
