Exhibit 99.1 CRISPR Therapeutics Provides Business Update and Reports Second Quarter 2026 Financial Results ZUG, Switzerland and BOSTON, August 3, 2026 – CRISPR Therapeutics (Nasdaq: CRSP) today reported financial results for the second quarter ended June 30, 2026. "The second quarter reflected strong execution across CRISPR Therapeutics' portfolio and platform," said Samarth Kulkarni, Ph.D., Chairman and Chief Executive Officer of CRISPR Therapeutics. "CASGEVY's momentum continued to build, highlighted by the FDA's approval for children as young as 2 years old, while we expanded our in vivo pipeline with the initiation of Phase 1 clinical trials for CTX340 for refractory hypertension and CTX460 for alpha-1 antitrypsin deficiency. We enter the second half of 2026 well positioned, with a number of important milestones ahead across our pipeline." Recent Highlights and Outlook Hemoglobinopathies and CASGEVY® (exagamglogene autotemcel) CASGEVY is a non-viral, ex vivo, CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or TDT that has been shown to reduce or eliminate vaso-occlusive crises (VOCs) for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved in 39 countries across North America, Europe, and the Middle East. • CASGEVY generated second quarter 2026 revenue of $76 million, representing 78% growth quarter-over- quarter and 151% growth year-over-year. • The U.S. FDA recently approved CASGEVY in children 2 years of age and older with SCD or TDT, the first genetic therapy indicated for children as young as 2 years for both SCD and TDT. With this approval, achieved in just 53 days post filing, approximately 5,500 patients with SCD or TDT may be eligible for treatment with CASGEVY for the first time. Regulatory submissions have also been completed for CASGEVY in the Kingdom of Saudi Arabia (KSA) and the United Kingdom (U.K.) for the treatment of children 5 to 11 years of age. • In May, Vertex secured reimbursement for CASGEVY for eligible patients 12 years and older with SCD or TDT in Germany. Efforts remain underway with government and reimbursement authorities globally to ensure sustainable access for eligible patients. • CRISPR Therapeutics continues to advance its in vivo hematopoietic stem cell editing approach using lipid nanoparticle (LNP)-mediated delivery. This approach has the potential to expand the addressable patient populations for SCD and TDT. In Vivo Liver Editing CRISPR Therapeutics continues to advance a diversified portfolio of in vivo gene editing programs leveraging its proprietary liver-directed LNP delivery platform. • Development of CTX310®, an investigational therapy targeting angiopoietin-related protein 3 (ANGPTL3), continues in a Phase 1b clinical trial, with the Company prioritizing indications in severe hypertriglyceridemia (sHTG) and refractory hypercholesterolemia. U.S. trials have been initiated, with ex- U.S. trials ongoing. • CRISPR Therapeutics announced that a late-breaking abstract entitled "Durability of Effects of CTX310, a CRISPR-Cas9 Gene Editing Targeting ANGPTL3" has been accepted for presentation at the European Society of Cardiology (ESC) Congress 2026 in Munich, Germany, on August 28 at 4:30 p.m. CET to discuss a clinical update of the ongoing Phase 1a trial. The Company also expects to provide a Phase 1b clinical update in the second half of 2026. • CTX340™, targeting angiotensinogen (AGT), has received IND clearance from the FDA.

The decrease in G&A expense was primarily attributable to a decrease in employee-related costs, including stock-based compensation expenses. • Collaboration Expense: Collaboration expense, net, was $40.3 million for the second quarter of 2026, compared to $45.2 million for the second quarter of 2025. The decrease was primarily attributable to an increase in the Company's share of CASGEVY revenue. • Net Loss: Net loss was $91.2 million for the second quarter of 2026, compared to a net loss of $208.5 million for the second quarter of 2025. About CASGEVY® (exagamglogene autotemcel [exa-cel]) CASGEVY® is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with sickle cell disease (SCD) or transfusion-dependent beta thalassemia (TDT), in which a patient’s own hematopoietic stem and progenitor cells are edited at the erythroid specific enhancer region of the BCL11A gene. This edit results in the production of high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. CASGEVY has been shown to reduce or eliminate VOCs for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved for eligible SCD and TDT patients 12 years and older by multiple regulatory bodies around the world.
