**5.1 Full Description of Material Change**

On March 26, 2026, Dolly Varden and Contango completed their previously announced Arrangement following receipt of all required shareholder and court approvals.

On completion of the Arrangement, all issued and outstanding Dolly Varden Shares were acquired by 1566004 B.C. Ltd. ("**Acquireco**"), an indirect wholly owned subsidiary of Contango, under a statutory plan of arrangement. Each Dolly Varden Share has been exchanged for 0.1652 of a Contango Share, or, for Eligible Holders (as such term is defined in the Arrangement Agreement, as defined below) who validly elected, 0.1652 of an exchangeable share in the capital of Acquireco (each whole share being, an "**Exchangeable Share**"), in each case subject to the terms and conditions of the arrangement agreement dated December 7, 2025, as amended February 11, 2026, between the Contango, Dolly Varden and Acquireco (the "**Arrangement Agreement**").

The Exchangeable Shares are exchangeable for Contango Shares on a one-for-one basis subject to adjustment.
