Accounting Standards Update ("ASU") 2025-05 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets

On January 1, 2026, the Company prospectively adopted ASU 2025-05, which simplifies estimating credit losses on current accounts receivable and current contract assets. Under the new guidance, CPKC elected to adopt a practical expedient allowing the Company to assume that conditions existing as of the balance sheet date will remain unchanged over the remaining life of the asset when developing reasonable and supportable forecasts for estimating expected credit losses. Adoption of ASU 2025-05 did not have a material impact on the Company's Interim Consolidated Financial Statements.

Other accounting standards that became effective during the three and six months ended June 30, 2026, did not have a material impact on the Company's Interim Consolidated Financial Statements. Recently issued accounting pronouncements are not expected to have a material impact on the Company's financial position or results of operations upon adoption.
