Grail Shares Rise After TD Cowen Lifts Rating Despite Trial Setback
GRAL

Grail Inc. stock climbed 6.2% Wednesday following TD Cowen's upgrade to Buy from Hold and a revised $65 price target. The upgrade comes after the company's pivotal NHS Galleri trial failed to meet its primary endpoint, a result that previously pushed shares down roughly 60%. TD Cowen highlights a $70 billion total addressable market for multi-cancer early detection and reports favorable feedback from key opinion leaders on regulatory prospects.

Key Points

  • TD Cowen upgraded Grail to Buy from Hold and lowered its price target to $65 from $114.
  • The upgrade follows Grail’s pivotal NHS Galleri trial missing its primary endpoint, which previously drove the stock down about 60%.
  • TD Cowen values the multi-cancer early detection market at $70 billion and reports KOL feedback that supports potential FDA approval; Medicare approval probability estimated at about 50%.

Shares of Grail Inc. (NASDAQ:GRAL) rose 6.2% on Wednesday after TD Cowen moved its rating on the company from Hold to Buy and set a new price target of $65.00, reduced from the prior $114.00 target.

The upgrade follows a significant clinical setback for Grail in its pivotal NHS Galleri study, which failed to achieve its primary endpoint and led to a roughly 60% decline in the stock earlier. Despite that outcome, TD Cowen analyst Dan Brennan outlined a constructive view of the broader multi-cancer early detection (MCED) market.

In firm research cited around the upgrade, TD Cowen valued the MCED opportunity at $70 billion. As Brennan commented: "We’re constructive on the Multi-Cancer Early Detection Market (MCED), whose TAM we sized at $70B in our detailed recent coverage initiation," adding: "We believe MCED testing will represent a paradigm shift in cancer and enable millions of individuals to have the potential to catch previously unscreened cancers earlier, extending life."

Brennan acknowledged that some market participants deem the NHS Galleri trial a clear failure. However, he said diligence conversations with key opinion leaders since the results were released have painted a more optimistic picture for Grail’s regulatory pathway and commercial prospects.

TD Cowen reported that feedback from those key opinion leaders supports the case for potential FDA approval. The analyst also estimated the probability of Medicare approval at approximately 50% and noted an upward bias to that probability assessment.

The firm’s revised $65 price target was highlighted as implying roughly 37% upside from Grail’s $47 closing share price immediately prior to Wednesday’s trading session.


Market context: The stock reaction reflects investor reassessment after the trial miss and TD Cowen’s updated view, balancing the clinical disappointment against the size of the addressable market and supportive expert feedback.

What remains uncertain: The company’s recent trial results and the timing and likelihood of regulatory and reimbursement approvals continue to be material variables for Grail’s valuation and commercial potential.

Risks

  • The NHS Galleri trial missed its primary endpoint, a clinical outcome that materially impacts regulatory and commercial prospects - relevant to biotech and diagnostics sectors.
  • Regulatory approval and Medicare coverage remain uncertain - this affects reimbursement dynamics for healthcare payers and diagnostics companies.
  • Market volatility driven by clinical data interpretation could continue to affect stock performance in the short term - relevant to equity markets and healthcare investors.
