Recent Updates on RGEN stock Over the past 24 hours, sentiment on Repligen has improved as the company announced three new high-performance chromatography resins—AVIPure HiPer AAV9, AVIPure HiPer AAV8, and HiPer QA—expanding its proteins portfolio and reinforcing its positioning in next‑generation bioprocessing ahead of a broader resin rollout expected in 2026. This product innovation, combined with a constructive industry backdrop, has driven several analysts to lift their valuation views: Wells Fargo cited reduced U.S. policy uncertainty for pharma and well‑anchored but still potentially conservative forward growth expectations in the tools space, while Barclays pointed to its refreshed 2026 outlook for life sciences and diagnostics tools, emphasizing that end markets are recovering and that tools companies, including Repligen, are relatively under-owned in healthcare, creating what it views as a favorable setup for outperformance. These factors together underpin the recent positive reassessments of Repligen’s prospects and have supported a stronger near-term trading tone in the stock.
