This unaudited interim consolidated financial information of Canadian Pacific Railway Limited ("CPRL") and its subsidiaries (collectively, “CP”, or “the Company”), expressed in Canadian dollars, reflects management’s estimates and assumptions that are necessary for its fair presentation in conformity with generally accepted accounting principles in the United States of America (“GAAP”). It does not include all disclosures required under GAAP for annual financial statements and interim financial statements, and should be read in conjunction with the 2021 annual consolidated financial statements and notes included in CP's 2021 Annual Report on Form 10-K and 2022 interim consolidated financial statements. The accounting policies used are consistent with the accounting policies used in preparing the 2021 annual consolidated financial statements.

CP's operations can be affected by seasonal fluctuations such as changes in customer demand and weather-related issues. This seasonality could impact quarter-over-quarter comparisons.

In management’s opinion, the unaudited interim consolidated financial information includes all adjustments (consisting of normal and recurring adjustments) necessary to present fairly such information. Interim results are not necessarily indicative of the results expected for the fiscal year.

During the fourth quarter and for the year ended December 31, 2022, the Company recorded a deferred tax recovery of $24 million to reverse an uncertain tax position as this amount is no longer expected to be realized.

During the fourth quarter and for the year ended December 31, 2022, the Company recorded a deferred tax recovery of $27 million and $19 million, respectively, on the outside basis difference of the change in the equity investment in KCS.

During the fourth quarter and for the year ended December 31, 2021, the Company recorded a deferred tax recovery of $33 million on the outside basis difference of the change in the equity investment in KCS from initial recognition on December 14, 2021.

On December 14, 2021, the Company purchased 100% of the issued and outstanding shares of KCS. From December 14, 2021, the date of purchase, all purchased shares of KCS are held in an independent voting trust (the "Trust") pending the approval from the U.S. Surface Transportation Board ("STB") of the Company's application for control of KCS.

The Company accounts for its investment in KCS using the equity method of accounting while the STB considers the Company's application to control KCS. The STB review of CP's proposed control of KCS while KCS is in the voting trust is expected to be completed in the first quarter of 2023. The investment in KCS of $45,091 million as at December 31, 2022, includes $1,074 million of equity earnings of KCS and foreign currency translation of $2,891 million, offset by dividends of $1,157 million received in the year ended December 31, 2022. Included within the $447 million and $1,074 million of equity earnings of KCS recognized for the three months and year ended December 31, 2022 was amortization (net of tax) of basis differences of $42 million and $163 million, respectively. These basis differences relate to depreciable property, plant and equipment, intangible assets with definite lives, and long-term debt, and are amortized over the related assets' remaining useful lives, and the remaining terms to maturity of the debt instruments.

During the fourth quarter and for the year ended December 31, 2022, the Company incurred $17 million and $74 million, in acquisition-related costs, respectively, recorded within "Purchased services and other" in the Company's Interim Consolidated Statements of Income.

Acquisition-related costs of $10 million and $49 million incurred by KCS during the fourth quarter and for the year ended December 31, 2022 are included within "Equity (earnings) loss of Kansas City Southern" in the Company's Interim Consolidated Statements of Income. Equity earnings of KCS recognized for the three months and year ended December 31, 2022 also included KCS's gain on unwinding of interest rate hedges of $212 million, which is net of CP's associated purchase accounting basis differences and tax.

During the fourth quarter and for the year ended December 31, 2021, the Company incurred $157 million and $599 million, respectively, in acquisition-related costs associated with the KCS acquisition, of which costs of $36 million and $183 million were recorded within "Purchased services and other", and recoveries of $48 million and costs of $247 million were recorded within "Other expense (income)" in each period, respectively. Acquisition-related costs, net of tax, of $169 million, incurred by KCS during the 18 days from the date the transaction closed into the voting trust, were included within "Equity loss of Kansas City Southern" in the Company's Interim Consolidated Statements of Income.

(1)This earnings measure has no standardized meaning prescribed by GAAP and, therefore, is unlikely to be comparable to similar measures presented by other companies. This measure is defined and reconciled in Non-GAAP Measures of this Earnings Release.

(1)This earnings measure has no standardized meaning prescribed by GAAP and, therefore, is unlikely to be comparable to similar measures presented by other companies. This measure is defined and reconciled in Non-GAAP Measures of this Earnings Release.

(1)Average train speed is defined as a measure of the line-haul movement from origin to destination including terminal dwell hours. It is calculated by dividing the total train miles travelled by the total train hours operated. This calculation does not include delay time related to customers or foreign railroads and excludes the time and distance travelled by: i) trains used in or around CP’s yards; ii) passenger trains; and iii) trains used for repairing track.

(2)Locomotive productivity is defined as daily GTMs divided by daily average operating horsepower. Operating horsepower excludes units offline, tied up or in storage, or in use on other railways, and includes foreign units online.

(3)Fuel efficiency is defined as U.S. gallons of locomotive fuel consumed per 1,000 GTMs.

(4)Includes gallons of fuel consumed from freight, yard and commuter service but excludes fuel used in capital projects and other non-freight activities.

(5)An employee is defined as an individual currently engaged in full-time, part-time, or seasonal employment with CP.

(6)Workforce is defined as total employees plus contractors and consultants.

(7)FRA personal injuries per 200,000 employee-hours for the three months ended December 31, 2021 was previously reported as 0.71, restated to 0.75 in this Earnings Release. This restatement reflects new information available within specified periods stipulated by the FRA but that exceed the Company's financial reporting timeline.

The Company presents Non-GAAP measures to provide a basis for evaluating underlying earnings and liquidity trends in the Company’s business that can be compared with the results of operations in prior periods. In addition, these Non-GAAP measures facilitate a multi-period assessment of long-term profitability, allowing management and other external users of the Company’s consolidated financial information to compare profitability on a long-term basis, including assessing future profitability, with that of the Company’s peers.

These Non-GAAP measures have no standardized meaning and are not defined by accounting principles generally accepted in the United States of America ("GAAP") and, therefore, may not be comparable to similar measures presented by other companies. The presentation of these Non-GAAP measures is not intended to be considered in isolation from, as a substitute for, or as superior to the financial information presented in accordance with GAAP.

The Company uses adjusted earnings results including Adjusted income, Adjusted diluted earnings per share, Adjusted operating income and Adjusted operating ratio to evaluate the Company’s operating performance and for planning and forecasting future business operations and future profitability. Core adjusted income and Core adjusted diluted earnings per share are presented to provide financial statement users with additional transparency by isolating for the impact of KCS purchase accounting. KCS purchase accounting represents the amortization of basis differences, being the difference in value between the consideration paid to acquire KCS and the underlying carrying value of the net assets of KCS immediately prior to its acquisition by the Company, net of tax, as recognized within Equity (earnings) loss of Kansas City Southern in the Company's Interim Consolidated Statements of Income. All assets subject to KCS purchase accounting contribute to income generation and will continue to amortize over their estimated useful lives. These Non-GAAP measures provide meaningful supplemental information regarding operating results because they exclude certain significant items that are not considered indicative of future financial trends either by nature or amount or provide improved comparability to past performance. As a result, these items are excluded for management assessment of operational performance, allocation of resources and preparation of annual budgets. These significant items may include, but are not limited to, restructuring and asset impairment charges, individually significant gains and losses from sales of assets, acquisition-related costs, the merger termination payment received, KCS's gain on unwinding of interest rate hedges (net of CP's associated purchase accounting basis differences and tax), as recognized within Equity (earnings) loss of Kansas City Southern in the Company's Interim Consolidated Statements of Income, the foreign exchange ("FX") impact of translating the Company’s debt and lease liabilities (including borrowings under the credit facility), discrete tax items, changes in the outside basis tax difference between the carrying amount of CP's equity investment in KCS and its tax basis of this investment, changes in income tax rates, changes to an uncertain tax item, and certain items outside the control of management. Acquisition-related costs include legal, consulting, financing fees, integration planning costs consisting of third-party services and system migration, fair value gain or loss on FX forward contracts and interest rate hedges, FX gain on U.S. dollar-denominated cash on hand from the issuances of long-term debt to fund the KCS acquisition, and transaction and integration costs incurred by KCS, net of tax, which were recognized within Equity (earnings) loss of Kansas City Southern in the Company's Interim Consolidated Statements of Income. These items may not be non-recurring. However, excluding these significant items from GAAP results allows for a consistent understanding of the Company's consolidated financial performance when performing a multi-period assessment including assessing the likelihood of future results. Accordingly, these Non-GAAP financial measures may provide insight to investors and other external users of the Company's consolidated financial information.

The following tables reconcile the most directly comparable measures presented in accordance with GAAP to the Non-GAAP measures:

Adjusted income is calculated as Net income reported on a GAAP basis adjusted for significant items. Core adjusted income is calculated as Adjusted income less KCS purchase accounting.

(1) The tax effect of adjustments was calculated as the pre-tax effect of the adjustments multiplied by the applicable tax rate for the above items of 5.84% and 16.97% for the three months and year ended December 31, 2022, respectively, and 2.27% and 0.51% for the three months and year ended December 31, 2021, respectively. The applicable tax rates reflect the taxable jurisdictions and nature, being on account of capital or income, of the significant items.

Adjusted diluted earnings per share is calculated using Adjusted income, as defined above, divided by the weighted-average diluted number of Common Shares outstanding during the period as determined in accordance with GAAP. Core adjusted diluted earnings per share is calculated as Adjusted diluted earnings per share less KCS purchase accounting.

(1) The tax effect of adjustments was calculated as the pre-tax effect of the adjustments multiplied by the applicable tax rate for the above items of 5.84% and 16.97% for the three months and year ended December 31, 2022, and 2.27% and 0.51% for the three months and year ended December 31, 2021, respectively. The applicable tax rates reflect the taxable jurisdictions and nature, being on account of capital or income, of the significant items.

Adjusted operating income is calculated as Operating income reported on a GAAP basis less significant items.

Adjusted operating ratio excludes those significant items that are reported within Operating income.

Return on average shareholders' equity is calculated as Net income divided by average shareholders' equity, averaged between the beginning and ending balance over a trailing twelve month period. Adjusted ROIC is calculated as Adjusted return divided by Adjusted average invested capital. Adjusted return is defined as Net income adjusted for interest expense, tax effected at the Company’s adjusted annualized effective tax rate, and significant items in the Company’s Consolidated Financial Statements, tax effected at the applicable tax rate. Adjusted average invested capital is defined as the sum of total Shareholders' equity, Long-term debt, and Long-term debt maturing within one year, as presented in the Company's Consolidated Financial Statements, each averaged between the beginning and ending balance over a trailing twelve month period, adjusted for the impact of significant items, tax effected at the applicable tax rate, on closing balances as part of this average.

Adjusted ROIC excludes significant items reported in the Company's Consolidated Financial Statements, as these significant items are not considered indicative of future financial trends either by nature or amount, and excludes interest expense, net of tax, to incorporate returns on the Company’s overall capitalization. Adjusted ROIC is a performance measure that measures how productively the Company uses its long-term capital investments, representing critical indicators of good operating and investment decisions made by management, and is an important performance criteria in determining certain elements of the Company's long-term incentive plan. Adjusted ROIC is reconciled below from Return on average shareholders' equity, the most comparable measure calculated in accordance with GAAP.

Calculation of Return on average shareholders' equity

Reconciliation of Net income to Adjusted return

(1) Tax was calculated at the adjusted annualized effective tax rate of 22.24% and 23.85% for the years ended December 31, 2022 and 2021, respectively.

(2) Tax was calculated as the pre-tax effect of the adjustments multiplied by the applicable tax rate for the above items of 16.97% and 0.51% for the years ended December 31, 2022 and 2021, respectively. The applicable tax rates reflect the taxable jurisdictions and nature, being on account of capital or income, of the significant items.

Reconciliation of Average shareholders' equity to Adjusted average invested capital

(1) Tax was calculated at the pre-tax effect of the adjustments multiplied by the applicable tax rate of 16.97% and 0.90% for the years ended December 31, 2022 and 2021, respectively. The applicable tax rate reflects the taxable jurisdictions and nature, being on account of capital or income, of the significant items.

Calculation of Adjusted ROIC

Free cash is calculated as Cash provided by operating activities, less Cash used in investing activities, adjusted for changes in Cash and cash equivalents balances resulting from FX fluctuations, the operating cash flow impacts of acquisition-related costs associated with the KCS transaction including settlement of cash flow hedges upon debt issuance and FX gain on U.S. dollar-denominated cash held to fund the KCS acquisition, the merger termination payment received related to KCS's termination of the Original Merger Agreement, and the acquisition of KCS. Free cash is a measure that management considers to be a valuable indicator of liquidity. Free cash is useful to investors and other external users of the Company's Consolidated Financial Statements as it assists with the evaluation of the Company's ability to generate cash to satisfy debt obligations and discretionary activities such as dividends, share repurchase programs, and other strategic opportunities, and is an important performance criteria in determining certain elements of the Company's long-term incentive plan. The acquisition-related costs and the merger termination fee related to the KCS acquisition are not indicative of operating trends and have been excluded from Free cash. The acquisition of KCS is not indicative of investment trends and has also been excluded from Free cash. Free cash should be considered in addition to, rather than as a substitute for, Cash provided by operating activities.

Reconciliation of Cash Provided by Operating Activities to Free Cash

FX adjusted % change allows certain financial results to be viewed without the impact of fluctuations in foreign currency exchange rates, thereby facilitating period-to-period comparisons in the analysis of trends in business performance. Financial result variances at constant currency are obtained by translating the comparable period of the prior year results denominated in U.S. dollars at the foreign exchange rates of the current period.

FX adjusted % changes in revenues are further used in calculating FX adjusted % change in freight revenue per carload and RTM. FX adjusted % changes in revenues are as follows:

FX adjusted % changes in operating expenses are as follows:

FX adjusted % change in operating income is as follows:

Dividend payout ratio is calculated as dividends declared per share divided by Diluted EPS. Core adjusted dividend payout ratio is calculated as dividends declared per share divided by Core adjusted diluted EPS, as defined above. This ratio is a measure of shareholder return and provides information on the Company's ability to declare dividends on an ongoing basis, excluding significant items and the impact of KCS purchase accounting.

Starting with this Earnings Release, Core adjusted dividend payout ratio is presented to provide users with additional transparency by isolating for the impact of KCS purchase accounting.

Calculation of Dividend Payout Ratio

Calculation of Core Adjusted Dividend Payout Ratio

Adjusted net debt to Adjusted earnings before interest, tax, depreciation and amortization ("EBITDA") ratio is calculated as Adjusted net debt divided by Adjusted EBITDA. The Adjusted net debt to Adjusted EBITDA ratio is a key credit measure used to assess the Company’s financial capacity. The ratio provides information on the Company’s ability to service its debt and other long-term obligations from operations, excluding significant items, and is an important performance criteria in determining certain elements of the Company's long-term incentive plan. The Adjusted net debt to Adjusted EBITDA ratio is reconciled below from the Long-term debt to Net income ratio, the most comparable measure calculated in accordance with GAAP.

Beginning in the first quarter of 2022, CP added disclosure of Pro-forma adjusted net debt to Pro-forma adjusted EBITDA ratio to better align with CP’s debt covenant calculation, which incorporates the trailing twelve month adjusted EBITDA of KCS as well as KCS’s outstanding debt. CP is incorporating the trailing twelve month adjusted EBITDA of KCS on a pro-forma basis, as CP is not entitled to earnings prior to the acquisition date of December 14, 2021. CP does not control KCS while it is in the voting trust during review of our merger application by the STB, though CP is the beneficial owner of KCS’s outstanding shares and receives cash dividends from KCS. The adjustment to include the trailing twelve month EBITDA and KCS’s outstanding debt provides users of the financial statements with better insight into CP’s progress in achieving deleveraging commitments. KCS’s disclosed U.S. dollar financial values for the years ended December 31, 2022 and December 31, 2021 were adjusted to Canadian dollars reflecting the FX rate for the appropriate period presented, respectively.
