Suncor Energy Inc. furnished a Form 6-K on May 14, 2026, reporting that it has submitted its Extractive Sector Transparency Measures Act report for the reporting year January 1, 2025 through December 31, 2025. The exhibit listed with the filing is “Suncor Energy Inc. Extractive Sector Transparency Measures Act Report for the reporting year January 1, 2025 to December 31, 2025.” The filing does not report an insider trade, equity issuance, debt transaction, merger, dividend, share repurchase, or other securities-related corporate action. There are no disclosed purchases or sales of Suncor securities, no transaction codes, no share counts, no prices, no vesting schedules, and no post-transaction ownership figures. Instead, the action reported is a regulatory transparency disclosure tied to Suncor’s extractive-sector operations. Canada’s Extractive Sector Transparency Measures Act requires covered companies in the oil, gas, and mining industries to report certain payments made to governments and government-related entities. Such reports are intended to provide public visibility into payments such as taxes, royalties, fees, production entitlements, bonuses, dividends, and infrastructure-related payments, when applicable. The Form 6-K was signed on behalf of Suncor by Shawn Poirier, Assistant Corporate Secretary, on May 14, 2026. Because the filing text provided includes only the cover page and exhibit index, it identifies the existence and reporting period of the transparency report but does not include the underlying payment data or jurisdiction-by-jurisdiction details that would typically appear in the exhibit itself.
