Arcus Biosciences shares fell 19.58% to $19.10 on Tuesday. The sharp decline was driven by the announcement of a $250 million public offering of common stock and the release of kidney-cancer data for casdatifan.

What Happened

The company announced the pricing of a $250 million public offering of common stock, with a price range of $17.50 to $18.50. The offering includes a 30-day underwriter option for up to 15% more shares. This capital raise coincided with the release of data for casdatifan in kidney cancer, which contributed to the sell-off. Additionally, Kuehn Law, PLLC, announced it is investigating whether certain officers and directors of Arcus Biosciences breached their fiduciary duties.

What The Data Shows

The stock printed 81 fresh 52-week lows on October 21, 2026. Over the last eight sessions, the stock moved down 21.5%, falling from $24.34 to $19.10. The 52-week range is $16.35 to $31.73. Fundamentals show a market cap of $2.8 billion, with trailing twelve-month revenue down 55.3% and an EPS of $3.86. The net margin stands at -393.2%.
