**Silence Therapeutics Reports Third Quarter 2025 Financial Results and Recent Business Highlights**

*SANRECO Phase 2 study of divesiran in polycythemia vera (PV) fully enrolled; topline results anticipated in 3Q 2026*

*Strong balance sheet and cash runway into 2028* 

6 November 2025

LONDON, Silence Therapeutics plc, Nasdaq: SLN ("Silence" or "the Company"), a global clinical-stage company developing novel siRNA (short interfering RNA) therapies, today reported its financial results for the third quarter ended September 30, 2025, and reviewed recent business highlights.

"Silence continues to focus on operational execution, highlighted by the rapid achievement of full enrollment in our ongoing SANRECO Phase 2 study of divesiran, our first-in-class siRNA for PV," said Craig Tooman, President and Chief Executive Officer at Silence. "We believe the positive momentum in our divesiran PV program, combined with exciting advancements in our early-stage pipeline, positions us well for both near and long-term value creation. We are looking forward to a strong finish to the year and meaningful pipeline catalysts ahead in 2026."

Rhonda Hellums, Silence's Chief Financial Officer, said, "With a strong cash position providing a runway into 2028, we remain focused on executing to deliver topline Phase 2 data in PV next year, bringing forward additional candidates from our mRNAi GOLD™ platform where we see promising opportunities and advancing our extra-hepatic work."

**<u>Recent Highlights</u>**

**Divesiran for Polycythemia Vera (PV)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Completed enrollment in the SANRECO Phase 2 study of divesiran for the treatment of PV. The Phase 2 portion of SANRECO is a global, randomized, double-blind, placebo-controlled trial that enrolled 48 phlebotomy-dependent PV patients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Following accelerated completion of Phase 2 enrollment, initial topline results from SANRECO are anticipated in the third quarter of 2026.

**<u>Third Quarter 2025 Financial Highlights</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Cash Position:** Cash and cash equivalents, and short-term investments of $102.2 million as of September 30, 2025, which are expected to fund our operational plans into 2028.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Research & Development Expenses:** R&D expenses were $20.5 million for the quarter ended September 30, 2025, as compared to $20.2 million for the quarter ended September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**General & Administrative Expenses:** G&A expenses were $5.8 million for the quarter ended September 30, 2025, as compared to $7.7 million for the quarter ended September 30, 2024. The $1.9 million decrease in G&A expenses was primarily due to a reduction in reporting and compliance requirements, as well as our efforts to increase operating efficiencies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Net Loss:** Net loss was $21.0 million for the quarter ended September 30, 2025, as compared to $35.5 million for the quarter ended September 30, 2024, which was impacted largely by foreign currency loss.
