The transaction, conducted near the stock's 52-week high, was performed to fulfill tax withholding on recently vested restricted stock units, as stipulated by the company's equity incentive plan, and not as a discretionary sale.

The firm also progresses with a new program to provide investigational therapy access to certain Duchenne muscular dystrophy patients.

In recent operational developments, Avidity Biosciences initiated a Managed Access Program for delpacibart zotadirsen, an investigational drug targeting patients suffering from Duchenne muscular dystrophy with mutations eligible for exon 44 skipping. Authorized under an FDA treatment protocol, this program will permit eligible U.S. patients to receive the therapy, with enrollment anticipated to commence by year-end.

A major corporate event shaping Avidity’s current landscape is Novartis' agreement to acquire the company for approximately $12 billion, representing a cash offer of $72 per share. This announcement prompted impacts on analyst opinions; Chardan Capital Markets responded by downgrading Avidity’s stock from Buy to Neutral and adjusting their price target downward from $75.00 to $72.00. Similarly, TD Cowen shifted their recommendation from Buy to Hold and lowered the price target from $78.00 to $74.00, while maintaining the Hold rating. TD Cowen also highlighted that the company's Phase 2/3 del-brax FSHD biomarker cohort data remains on track for a 2026 release, signaling ongoing clinical progress amid strategic transitions.

These insider sales, acquisition proceedings, and program launches collectively underscore a transformative period for Avidity Biosciences as it navigates integration with Novartis and advances its drug development pipeline.

Risks

  • Avidity Biosciences' current unprofitable status poses ongoing financial risk as the company transitions through acquisition and drug development phases.
