CAMBRIDGE, Mass., Aug. 7, 2025 – Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today reported operational highlights and financial results for the second quarter ended June 30, 2025.

"We are exceeding many of our internal expectations," said Intellia President and Chief Executive Officer John Leonard, M.D. "The enthusiasm from both patients and physicians for Intellia's late-stage programs has resulted in strong enrollment numbers that allow us to plan to enhance the Phase 3 MAGNITUDE trial in ATTR-CM and accelerate completion of the Phase 3 HAELO study in HAE ahead of our original plans. We are full steam ahead in achieving our mission of getting one-time therapies to more patients."

**Second Quarter 2025 and Recent Operational Highlights**

**Hereditary Angioedema (HAE)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Lonvoguran ziclumeran (lonvo-z, also known as NTLA-2002):** Lonvo-z is a wholly owned, investigational *in vivo* CRISPR-based therapy designed to knock out the *KLKB1* gene in the liver, with the goal of lifelong control of HAE attacks after a single dose.

oRecruitment ended earlier than expected during the second quarter and the Company now expects to complete randomization in the global Phase 3 HAELO study during the third quarter 2025.

oIntellia presented three-year follow-up data from the Phase 1 portion of the ongoing Phase 1/2 study after receiving a single dose of lonvo-z. Results were shared in an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2025 on June 15 in Glasgow, United Kingdom. In the Phase 1 portion of the study, a one-time dose of 25 mg (N=3), 50 mg (N=4) or 75 mg (N=3) of lonvo-z was administered via intravenous infusion and plasma kallikrein protein levels were measured along with HAE attacks. At the time of the February 12, 2025 data cutoff, all 10 patients were attack-free and treatment-free for a median of nearly two years. With up to three years of follow-up, a single dose of lonvo-z led to a mean reduction in monthly HAE attack rate of 98% over the study period, compared to pre-treatment baseline. For all 10 patients, deep, dose-dependent and durable reductions in plasma kallikrein protein continued to be observed through the latest assessment. Across all three dose levels, lonvo-z was generally well tolerated and showed a safety profile consistent with earlier data presented at EAACI in 2024. The most frequent adverse events during the study period were infusion-related reactions (IRRs). IRRs were mostly Grade 1 and resolved with all patients receiving the full dose. With up to three years of follow-up, no treatment-emergent serious adverse events were observed, and no treatment-related adverse events were observed during the period following 28 days after dosing.

oIntellia expects to present additional data from the ongoing Phase 1/2 study in the second half of 2025.

oThe Company is on track to submit a Biologics License Application (BLA) in the second half of 2026.

**Transthyretin (ATTR) Amyloidosis**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Nexiguran ziclumeran (nex-z, also known as NTLA-2001)**: Nex-z is an investigational *in vivo* CRISPR-based therapy designed to inactivate the *TTR* gene in liver cells, thereby preventing the production of transthyretin (TTR) protein for the treatment of ATTR amyloidosis. Nex-z offers the

Page 2 of 8 intelliatx.com

------

possibility of halting and reversing the disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a single dose. Intellia leads development and commercialization of nex-z in collaboration with Regeneron Pharmaceuticals, Inc.

o**ATTR Amyloidosis with Cardiomyopathy (ATTR-CM):** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Enrollment in the global Phase 3 MAGNITUDE trial is progressing ahead of the Company's projections and the Company is tracking to enroll at least 650 patients cumulatively by year-end. Intellia is amending the MAGNITUDE study to expand enrollment to approximately 1,200 patients from 765 patients, subject to health authority review. Expanding the patient number in the study would provide a more robust dataset, particularly in the stabilizer stratum, which we believe will be very important to patients, clinicians, and payers. This change has no expected impact on previously projected enrollment timelines or the Company's projected cash runway.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In May 2025, the Company presented Phase 1 wild-type vs. variant ATTR-CM data at the Heart Failure 2025 Meeting in Belgrade, Serbia. The data showed that nex-z reduced TTR production and showed promise for treating both wild-type (ATTRwt) and variant (ATTRv) ATTR-CM with a favorable safety profile. Absolute TTR levels dropped from 222.4 to 16.5 μg/mL (ATTRwt) and 132.0 to 16.6 μg/mL (ATTRv). Functional capacity and clinical biomarkers were favorably impacted in both patient groups. Evidence of stability or improvement in disease progression markers were observed across both populations at similar rates. The most commonly reported treatment-related adverse events were IRR, which were mild or moderate, and did not result in any discontinuations. Observed liver enzyme abnormalities were not considered serious, were asymptomatic and resolved spontaneously without medical intervention or sequelae.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Intellia expects to present longer-term data from ATTR-CM patients in the Phase 1 study in the second half of 2025. The data will include updated measures of clinical efficacy and safety.

o**Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN):**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Enrollment is ahead of schedule in the global Phase 3 MAGNITUDE-2 study. Intellia now expects enrollment to be completed in the first half of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In May 2025, the Company presented positive two-year follow-up Phase 1 data in an oral presentation at the 2025 Peripheral Nerve Society (PNS) Annual Meeting in Edinburgh, United Kingdom. Across patients who received a one-time dose of 0.3 mg/kg or higher (n=33), the mean serum TTR reduction by Day 28 was 90% (corresponding mean absolute serum TTR level of 23.8 µg/mL), with levels remaining

virtually unchanged through at least 24 months. Among the 18 patients with 24 month mNIS+7 endpoint assessments, 13 showed improvements of ≥ 4 points, which is considered to be a clinically meaningful threshold. Most of the patients in the cohort who had progressed on patisiran improved, and only a single patient among the 18 had a deterioration of ≥ 4. Nex-z was generally well tolerated across all patients and at all dose levels tested. Treatment-related adverse events were consistent with those described for the cardiomyopathy population.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪In September 2025, the Company will present interim Phase 1 extended data in a symposium at the 5<sup>th</sup> International ATTR Amyloidosis Meeting for Patients and Doctors in Baveno, Italy.

**Platform and Company Updates**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Intellia is pioneering novel CRISPR-based gene editing technologies, such as gene writing and extrahepatic lipid nanoparticle (LNP) delivery technologies, to create highly differentiated *in vivo* and *ex vivo* product candidates. The Company's proprietary platform technologies are being researched and developed to expand therapeutics opportunities to support the mission of transforming lives of people with severe diseases, including the possibility of curative genome editing therapeutics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Intellia has expanded its commercial and medical affairs teams to build a strong foundation for commercial readiness. Since the beginning of the year, the company welcomed two key leaders: Jim McNinch, Vice President, U.S. Head of Sales and Ben Newman, Vice President, Commercial Operations, as well as several additional senior leaders with responsibilities for commercial data and field operations, marketing, pricing, patient services, market access, forecasting and medical communications. The company has largely completed the buildout of the commercial and medical affairs leadership teams.

**Second Quarter 2025 Financial Results** 

• **<u>Cash Position</u>:** Cash, cash equivalents and marketable securities were $630.5 million as of June 30, 2025, compared to $861.7 million as of December 31, 2024. The decrease in cash, cash equivalents and marketable securities includes approximately $65.0 million of non-recurring cash payments in the first half of 2025 associated with the Company's previously announced portfolio prioritization, workforce reduction, and real estate consolidation. The Company's cash, cash equivalents and marketable securities as of June 30, 2025 are expected to fund operations into the first half of 2027 and into the anticipated first commercial launch.

• **<u>Collaboration Revenue</u>:** Collaboration revenue was $14.2 million during the second quarter of 2025, compared to $6.9 million during the second quarter of 2024. The $7.3 million increase was mainly driven by cost reimbursements related to our collaboration with Regeneron Pharmaceuticals, Inc.

• **<u>R&D Expenses</u>:** Research and development (R&D) expenses were $97.0 million during the second quarter of 2025, compared to $114.2 million during the second quarter of 2024. The $17.2 million decrease was primarily driven by employee-related expenses, stock-based compensation, research materials and contracted services offset by an increase in the advancement of our lead programs. Stock-based compensation expense included in R&D expenses was $14.1 million for the second quarter of 2025.

• **<u>G&A Expenses</u>:** General and administrative (G&A) expenses were $27.2 million during the second quarter of 2025, compared to $31.8 million during the second quarter of 2024. The $4.6 million decrease was primarily related to lower stock-based compensation, offset in part by increased expenses related to the ongoing buildout of our commercial infrastructure. Stock-based compensation expense included in G&A expenses was $8.0 million for the second quarter of 2025.

• **<u>Net Loss</u>:** Net loss was $101.3 million for the second quarter of 2025, compared to $147.0 million during the second quarter of 2024.
