AI brief of an SEC Form 8-K · VISTA GOLD CORP (VGZ)

Vista Gold agrees to be acquired by Artemis Gold in share deal valued at $427 million

Positive Impact 5 of 5 m&a Written later

Vista Gold entered into an Arrangement Agreement on September 20, 2026, under which Artemis Gold would acquire all of Vista's common shares through a court-approved plan of arrangement. Vista shareholders would receive 0.0966 Artemis Gold shares for each Vista share, which the companies say implies US$2.83 per share and a 29% premium to Vista's 20-day volume-weighted average price. The deal requires Vista shareholder approval and other regulatory and court approvals, and the companies expect completion in January 2027.

Key points

  • Exchange ratio of 0.0966 Artemis Gold common shares per Vista Gold share, implying US$2.83 per share and a total transaction value of about US$427 million on a 100% basis
  • Premium of 29% to the 20-day VWAP as of September 18, 2026, and 25% to the last closing price, according to the companies
  • Vista must pay a termination fee of US$18,148,536 in certain circumstances, and either party may terminate if the Effective Time has not occurred by April 15, 2027
