System1 is trading at $4.05, +5.47%, after its board unanimously recommended rejecting Brave Bison’s unsolicited takeover offer as undervalued.

  • The response document said the proposed consideration represents a discount and lacks a control premium.
  • The company cited 11% revenue growth, while shareholders representing 21.61% of issued capital reportedly oppose the offer.
  • Broader markets and technology stocks are also higher, but the takeover development is the stronger catalyst behind the September 11, 2026 rebound after two consecutive declines.
