Vancouver, Canada – May 14, 2026 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB: 432) announces the adoption of semi-annual financial reporting. This news release is being filed pursuant to Coordinated Blanket Order 51 – 933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers (“CBO 51-933”).

CBO 51-933 allows eligible venture issuers to voluntarily move from a quarterly to a semi-annual financial reporting framework. Arbor's fiscal year ends on October 31. Under the provisions of CBO 51-933, Arbor will be exempt from the requirements to file its three-month and nine-month interim financial statements and associated management’s discussion and analysis (“MD&A”) as it meets the eligibility criteria under CBO 51-933, which include being a venture issuer with annual revenues of less than $10 million and maintaining a clean 12-month continuous disclosure record. Accordingly, Arbor will not be filing its interim financial statements for the nine-month period ending July 31, 2026 and associated MD&A.

Arbor will continue to file audited annual financial statements (due within 120 days of October 31, 2026) and six-month interim financial reports (due within 60 days of April 30, 2026). Arbor remains committed to timely disclosure and will continue to report all material changes and significant developments as required under National Instrument 51-102 – Continuous Disclosure Obligations.
