Insights

Equity capital markets analyst

Primary equity raise completed; modest concurrent strategic buy-in.

Perpetua Resources executed a marketed primary offering of 2,938,000 shares at $24.25, yielding $68.4 million in net proceeds on October 30, 2025. Terms include standard lock-ups (company 90 days; insiders and Paulson 60 days), which typically stabilize near-term secondary supply.

A concurrent private placement brings in Agnico Eagle for 280,415 shares at the same price, with expected net proceeds of $6.8 million. After the offering and this placement, and giving effect to Agnico’s warrants, Agnico’s beneficial ownership is cited at 8.7%.

Key near-term items are the completed closing of the underwritten deal on October 30, 2025 and the expected private placement closing on October 31, 2025. Actual market impact will depend on trading dynamics and adherence to lock-up provisions.
