CN reports strong third-quarter financial results

Productivity gains and cost management efforts drive Company's operating ratio to 57.9%

MONTREAL, October 22, 2019 — CN (TSX: CNR) (NYSE: CNI) today reported its financial and operating results for the third quarter ended September 30, 2019.

"CN delivered strong results, despite a softening economy,” said JJ Ruest, president and chief executive officer of CN. “Our team of experienced railroaders swiftly aligned resources with the weaker demand to achieve solid efficiency gains. We remain committed to our long-term agenda of growing faster than the economy at low incremental cost, and to taking Scheduled Railroading to the next level by deploying advanced operating technology.”

Financial results highlights

Third-quarter 2019 compared to third-quarter 2018


•	Revenues increased by four per cent, or C$142 million, to C$3,830 million.


•	Diluted earnings per share (EPS) increased by eight per cent (or 11 per cent on an adjusted basis ⁽¹⁾) to C$1.66.


•	Operating ratio of 57.9 per cent, an improvement of 1.6 points.


•	Operating income increased by eight per cent, or C$121 million, to C$1,613 million.


•	Strong balance sheet with adjusted debt-to-adjusted-EBITDA of less than 2.0X ⁽¹⁾.

Revised 2019 financial outlook⁽²⁾

In light of the deterioration in North American rail demand, as the economy continues to weaken, CN is now targeting to deliver 2019 adjusted diluted EPS growth in the high single-digit range this year versus last year's adjusted diluted EPS of C$5.50⁽¹⁾, compared with its July 23, 2019 financial outlook which called for low double-digit growth in adjusted diluted EPS; and now assumes slightly negative volume growth in 2019 in terms of revenue ton miles (RTMs).

Third-quarter 2019 revenues, traffic volumes and expenses

Revenues for the third quarter of 2019 were C$3,830 million, an increase of C$142 million or four per cent, when compared to the same period in 2018. The increase was mainly due to freight rate increases and higher intermodal revenues.

RTMs, measuring the relative weight and distance of freight transported by CN, declined by one per cent from the year-earlier period. Freight revenue per RTM increased by six per cent over the year-earlier period, mainly

driven by freight rate increases and higher intermodal revenues.

Operating expenses for the third quarter increased by one per cent to C$2,217 million, mainly driven by increased purchased services and material expense, as well as higher depreciation and amortization expense; partly offset by lower fuel costs and record fuel productivity.

Press Release

(1) Non-GAAP Measures

CN reports its financial results in accordance with United States generally accepted accounting principles (GAAP). CN also uses non-GAAP measures in this news release that do not have any standardized meaning prescribed by GAAP, such as adjusted performance measures. These non-GAAP measures may not be comparable to similar measures presented by other companies. For further details of these non-GAAP measures, including a reconciliation to the most directly comparable GAAP financial measures, refer to the attached supplementary schedule, Non-GAAP Measures.

CN's full-year adjusted diluted EPS outlook⁽²⁾excludes the expected impact of certain income and expense items, as well as those items noted in the reconciliation tables provided in the attached supplementary schedule, Non-GAAP Measures. However, management cannot individually quantify on a forward-looking basis the impact of these items on its EPS because these items, which could be significant, are difficult to predict and may be highly variable. As a result, CN does not provide a corresponding GAAP measure for, or reconciliation to, its adjusted diluted EPS outlook.

(2) Forward-Looking Statements

Certain statements included in this news release constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and under Canadian securities laws. By their nature, forward-looking statements involve risks, uncertainties and assumptions. The Company cautions that its assumptions may not materialize and that current economic conditions render such assumptions, although reasonable at the time they were made, subject to greater uncertainty. Forward-looking statements may be identified by the use of terminology such as "believes," "expects," "anticipates," "assumes," "outlook," "plans," "targets," or other similar words.

2019 key assumptions

CN has made a number of economic and market assumptions in preparing its 2019 outlook. The Company now assumes that North American industrial production for the year will increase in the range of 0.5 to one per cent (compared to its July 23, 2019 assumption of approximately one per cent), and continues to assume U.S. housing starts of approximately 1.25 million units and U.S. motor vehicle sales of approximately 17 million units. For the 2018/2019 crop year, the grain crops in both Canada and the United States were in line with their respective three-year averages. The Company assumes that the 2019/2020 grain crop in Canada will be in line with the three-year average and that the 2019/2020 grain crop in the United States will be below the three-year average. CN now assumes RTM volume growth in 2019 will be slightly negative compared to 2018 (compared to its July 23, 2019 assumption that total RTMs would increase in the mid single digits). CN assumes continued pricing above rail inflation. CN assumes that in 2019, the value of the Canadian dollar in U.S. currency will be approximately $0.75, and now assumes that in 2019 the average price of crude oil (West Texas Intermediate) will be in the range of US$55 to US$60 per barrel (compared to its July 23, 2019 assumption in the range of US$60 to US$65 per barrel). In 2019, CN plans to invest approximately C$3.9 billion in its capital program, of which C$1.6 billion is targeted toward track and railway infrastructure maintenance.

Forward-looking statements are not guarantees of future performance and involve risks, uncertainties and other factors which may cause the actual results or performance of the Company to be materially different from the outlook or any future results or performance implied by such statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements. Important risk factors that could affect the forward-looking statements include, but are not limited to, the effects of general economic and business conditions; industry competition; inflation, currency and interest rate fluctuations; changes in fuel prices; legislative and/or regulatory developments; compliance with environmental laws and regulations; actions by regulators; increases in maintenance and operating costs; security threats; reliance on technology and related cybersecurity risk; trade restrictions or other changes to international trade arrangements; transportation of hazardous materials; various events which could disrupt operations, including natural events such as severe weather, droughts, fires, floods and earthquakes; climate change; labor negotiations and disruptions; environmental claims; uncertainties of investigations, proceedings or other types of claims and litigation; risks and liabilities arising from derailments; timing and completion of capital programs; and other risks detailed from time to time in reports filed by CN with securities regulators in Canada and the United States. Reference should be made to Management's Discussion and Analysis (MD&A) in CN's annual and interim reports, Annual Information Form and Form 40-F, filed with Canadian and U.S. securities regulators and available on CN's website, for a description of major risk factors.

Forward-looking statements reflect information as of the date on which they are made. CN assumes no obligation to update or revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs, unless required by applicable securities laws. In the event CN does update any forward-looking statement, no inference should be made that CN will make additional updates with respect to that statement, related matters, or any other forward-looking statement.

This earnings news release, as well as additional information, including the Financial Statements, Notes thereto and MD&A, is contained in CN’s Quarterly Review available on the Company's website at www.cn.ca/financial-results and on SEDAR at www.sedar.com as well as on the U.S. Securities and Exchange Commission's website at www.sec.gov through EDGAR.

CN | 2019 Quarterly Review – Third Quarter 5

Non-GAAP Measures – unaudited

In this supplementary schedule, the "Company" or "CN" refers to Canadian National Railway Company, together with its wholly-owned subsidiaries. Financial information included in this schedule is expressed in Canadian dollars, unless otherwise noted.

CN reports its financial results in accordance with United States generally accepted accounting principles (GAAP). The Company also uses non-GAAP measures that do not have any standardized meaning prescribed by GAAP, including adjusted performance measures, constant currency, free cash flow and adjusted debt-to-adjusted EBITDA multiple. These non-GAAP measures may not be comparable to similar measures presented by other companies. From management's perspective, these non-GAAP measures are useful measures of performance and provide investors with supplementary information to assess the Company's results of operations and liquidity. These non-GAAP measures should not be considered in isolation or as a substitute for financial measures prepared in accordance with GAAP.

Adjusted performance measures

Management believes that adjusted net income, adjusted earnings per share, adjusted operating income and adjusted operating ratio are useful measures of performance that can facilitate period-to-period comparisons, as they exclude items that do not necessarily arise as part of CN's normal day-to-day operations and could distort the analysis of trends in business performance. Management uses adjusted performance measures, which exclude certain income and expense items in its results that management believes are not reflective of CN's underlying business operations, to set performance goals and as a means to measure CN's performance. The exclusion of such income and expense items in these measures does not, however, imply that these items are necessarily non-recurring. These measures do not have any standardized meaning prescribed by GAAP and therefore, may not be comparable to similar measures presented by other companies.

For the nine months ended September 30, 2019, the Company's adjusted net income was $3,293 million, or $4.56 per diluted share, which excludes a deferred income tax recovery of $112 million ($0.15 per diluted share) in the second quarter, resulting from the enactment of a lower provincial corporate income tax rate, and a depreciation and amortization expense of $84 million, or $62 million after-tax ($0.09 per diluted share) in the first quarter, related to costs previously capitalized for a Positive Train Control (PTC) back office system following the deployment of a replacement system.

For the three and nine months ended September 30, 2018, the Company's adjusted net income was $1,102 million, or $1.50 per diluted share, and $2,963 million, or $4.01 per diluted share, respectively. The adjusted figures for the three months ended September 30, 2018 exclude a gain on disposal of property located in Montreal, Quebec (the "Doney and St-Francois Spurs") of $36 million, or $32 million after-tax ($0.04 per diluted share). The adjusted figures for the nine months ended September 30, 2018 also exclude a gain on transfer of the Company’s finance lease in the passenger rail facilities in downtown Montreal, Quebec, together with its interests in related railway operating agreements (the “Central Station Railway Lease”) of $184 million, or $156 million after-tax ($0.21 per diluted share) and a gain on disposal of land located in Calgary, Alberta, excluding the rail fixtures (the “Calgary Industrial Lead”), of $39 million, or $34 million after-tax ($0.05 per diluted share), both in the second quarter.

The following table provides a reconciliation of net income and earnings per share, as reported for the three and nine months ended September 30, 2019 and 2018, to the adjusted performance measures presented herein:

The following table provides a reconciliation of operating income and operating ratio, as reported for the three and nine months ended September 30, 2019 and 2018, to the adjusted performance measures presented herein:

Adjusted operating ratio	57.9		%	59.5		%	60.7		%	61.6		%


(1)	Operating ratio is defined as operating expenses as a percentage of revenues.

Constant currency

Financial results at constant currency allow 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. Measures at constant currency are considered non-GAAP measures and do not have any standardized meaning prescribed by GAAP and therefore, may not be comparable to similar measures presented by other companies. Financial results at constant currency are obtained by translating the current period results denominated in US dollars at the foreign exchange rates of the comparable period in the prior year. The average foreign exchange rates were $1.32 and $1.33 per US$1.00 for the three and nine months ended September 30, 2019, respectively, and $1.31 and $1.29 per US$1.00 for the three and nine months ended September 30, 2018, respectively.

On a constant currency basis, the Company's net income for the three and nine months ended September 30, 2019 would have been lower by $5 million ($0.01 per diluted share) and $63 million ($0.09 per diluted share), respectively.

Free cash flow

Management believes that free cash flow is a useful measure of liquidity as it demonstrates the Company's ability to generate cash for debt obligations and for discretionary uses such as payment of dividends, share repurchases, and strategic opportunities. The Company defines its free cash flow measure as the difference between net cash provided by operating activities and net cash used in investing activities, adjusted for the impact of business acquisitions, if any. Free cash flow does not have any standardized meaning prescribed by GAAP and therefore, may not be comparable to similar measures presented by other companies.

The following table provides a reconciliation of net cash provided by operating activities as reported for the three and nine months ended September 30, 2019 and 2018, to free cash flow:



	Three months ended September 30						Nine months ended September 30
In millions	2019			2018			2019			2018
Net cash provided by operating activities	$	1,692		$	1,564		$	4,405		$	4,001

Management believes that the adjusted debt-to-adjusted earnings before interest, income taxes, depreciation and amortization (EBITDA) multiple is a useful credit measure because it reflects the Company's ability to service its debt and other long-term obligations. The Company calculates the adjusted debt-to-adjusted EBITDA multiple as adjusted debt divided by adjusted EBITDA. These measures do not have any standardized meaning prescribed by GAAP and therefore, may not be comparable to similar measures presented by other companies.

The following table provides a reconciliation of debt and net income to the adjusted measures presented below, which have been used to calculate the adjusted debt-to-adjusted EBITDA multiple:

The Company adopted Accounting Standards Update (ASU) 2016-02: Leases and related amendments (Topic 842) in the first quarter of 2019. The Company now includes operating lease liabilities, as defined by Topic 842, in adjusted debt and excludes operating lease cost, as defined by Topic 842, in adjusted EBITDA. Comparative balances previously referred to as present value of operating lease commitments and operating lease expense have not been adjusted and are now referred to as operating lease liabilities and operating lease cost, respectively.
