Biogen Inc. stock (US09062X1037): Q1 milestone payment amid partner C4 Therapeutics earnings

Biogen Inc., a leader in biotechnology focused on neurological and rare diseases, featured in partner C4 Therapeutics' first quarter 2026 financial results released on May 12, 2026. C4 Therapeutics (Nasdaq: CCCC) reported total revenue of $6.2 million for the period ended March 31, 2026, down from $7.2 million in Q1 2025. This decline stemmed from the end of a Merck research collaboration and prioritization of one KRAS project with Merck KGaA. Partially offsetting this was a $2.0 million milestone payment earned from Biogen during the quarter, according to GlobeNewswire as of 05/12/2026.
