Towers, Exchange Plaza, Bandra Kurla Complex Dalal Street, Mumbai - 400 001 Bandra (E), Mumbai – 400 051 Scrip Code: 543064 Scrip Symbol: COHANCE Dear Sir/Madam, Sub: Press Release Please find annexed press release – “Cohance Lifesciences advances its ADC strategy” We request you to take the above on record. Thanking you. Yours faithfully, For Cohance Lifesciences Limited (formerly, Suven Pharmaceuticals Limited) Sisir K Mishra Company Secretary & Compliance Officer Encl: As above. Cohance Lifesciences advances its ADC strategy Investment of USD 18 million in NJ Bio and Aruka Bio September 03, 2026: Cohance Lifesciences Limited today announced two proposed transactions to strengthen its Antibody-drug Conjugate (ADC) strategy: an additional investment of USD 13 million in NJ Bio and a controlling investment of USD 5 million in Aruka Bio. Both the transactions will be funded through internal accruals. The re-organisation establishes distinct priorities: deeper integration of NJ Bio’s customer- facing services with Cohance, and focused development of Aruka’s proprietary pipeline through potential partnerships. NJ Bio: planned succession, continued founder engagement Cohance will increase its common-equity ownership in NJ Bio from 56.0% to 67.3%, acquiring the entire holdings of Ms. Priyashri Nayak, and the Jain Family Irrevocable Trust. Dr. Jain will retain 32.7%. Dr. Jain will continue to lead NJ Bio while also advancing Aruka’s pipeline and partnership initiatives. NJ Bio will remain focused on customer-facing contract research, development and manufacturing services. Closer integration will combine its payload-linker and bioconjugation expertise with Cohance’s manufacturing capabilities to support customers end-to-end CRDMO development through commercial supply. This integration is expected to strengthen business performance across the combined platform over time. Aruka Bio: control of the platform, development with partners Aruka Bio, Inc. is a private biotechnology company based in Princeton, New Jersey, focused on developing next-generation antibody-drug conjugates. Its lead program is currently at the preclinical stage. Press Release Cohance’s USD 5 million equity investment will fund the buyout of other existing shareholders and convertible noteholders along with working capital. Following completion and Dr. Jain’s upfront equity grant, Aruka will be owned 65% directly by Cohance, 25% by NJ Bio and 10% by Dr. Jain. These percentages are before further dilution from Dr. Jain’s performance-linked equity award. Aruka will become Cohance’s direct subsidiary. The investment consolidates control of Aruka’s proprietary ADC platform, positioning it to pursue co-development, licensing and other collaborations with pharmaceutical and biotechnology partners as its pipeline progresses. This follows a review of NJ Bio's performance and integration with Cohance since the original investment in December 2024, which identified an opportunity to strengthen commercial alignment between the two businesses as NJ Bio expands its GMP CDMO services and to give dedicated leadership focus to Aruka's novel drug development pipeline. Completion is expected by the end of September 2026, subject to definitive agreements, applicable approvals and customary closing conditions. Dr. Naresh Jain, Founder and CEO, NJ Bio, said: “I will work across both businesses— supporting NJ Bio’s growth and an orderly leadership handover, while working together with Cohance in advancing Aruka’s pipeline and exploring development partnerships. Thereafter, I will focus full-time on Aruka as CEO, while continuing to support NJ Bio as a strategic advisor.” Umang Vohra, Executive Chairman and Group CEO, Cohance Lifesciences, said: “This reorganisation gives each business a clear focus: strengthening NJ Bio’s customer offering through closer integration with Cohance and creating the opportunity for Dr Jain to lead Aruka’s next phase. This integration is expected to strengthen business performance across the combined platform over time” -ENDS- Press Release About Cohance Lifesciences Cohance Lifesciences, formerly Suven Pharmaceuticals, is an innovator-focused global CRDMO formed through the merger of Cohance Life Sciences into Suven Pharmaceuticals.
