Regulus Adopts Shareholder Rights Plan and Provides Project Update

Shareholder Rights Plan - The Rights Plan is effective as of March 30, 2026, and is designed to protect shareholders by allowing them to purchase additional shares at a 50% discount if a person acquires 20% or more of the outstanding shares without following the plan's provisions [2][3]. - The plan requires approval from the TSX Venture Exchange and ratification by shareholders within six months, with a summary of the plan to be included in the management proxy circular for the 2026 annual meeting [4].
