CEO Commentary
"With strong customer engagement in all key markets, potash fundamentals continued to improve in the third quarter," said PotashCorp President and Chief Executive Officer Jochen Tilk. "In this environment, we delivered stronger potash results on record quarterly sales volumes and higher price realizations. Importantly, we expect that the rising consumption trends in place today will continue, with the potential for another record shipment year in 2018.

"We have made significant progress related to our merger with Agrium. On the regulatory front, we recently announced that we received clearance in Canada as well as in India - where we have committed to divesting three of our minority shareholdings. With approvals obtained in four jurisdictions and only the U.S. and China remaining, we continue to expect the merger of equals to close by the end of 2017 and are well-positioned to deliver on the strategic benefits and synergy potential of this transaction," said Tilk.

SASKATOON, Oct. 26, 2017 /PRNewswire/ - Potash Corporation of Saskatchewan Inc. (PotashCorp) reported third-quarter earnings of $0.06 per share ($53 million) - including a non-cash impairment charge in phosphate of $0.03 per share - bringing the nine-month total to $0.48 per share ($403 million). Results for the quarter were down from the $0.10 per share ($81 million) earned in the third quarter of 2016, while the nine-month total surpassed the $0.33 per share ($277 million) earned in the same period last year.

Gross margin was $230 million for the quarter and $753 million for the first nine months, exceeding 2016 levels of $190 million and $667 million, respectively, primarily due to higher potash contributions that more than offset weaker nitrogen and phosphate results. Cash from operating activities prior to working capital changes(4) of $290 million for the quarter and $935 million for the first nine months surpassed last year's totals of $247 million and $908 million for the same periods.

Investments in Arab Potash Company (APC) in Jordan, Israel Chemicals Ltd. (ICL) in Israel and Sociedad Quimica y Minera de Chile S.A. (SQM) in Chile contributed $35 million to our third-quarter earnings, bringing the total for the first nine months to $132 million. Totals for both the third quarter and first nine months exceeded the respective amounts generated last year, which also included a dividend from Sinofert Holdings Limited (Sinofert) in China. The market value of our investments in these four publicly traded companies was approximately $6.6 billion,(5) or $8 per PotashCorp share, at market close on October 25, 2017.

Market Conditions
Global potash prices improved for the fifth consecutive quarter as agronomic need and affordability led to strong demand in all major markets. Shipments to China and India accelerated following contract settlements early in the third quarter while deliveries to Latin America continued at a record pace. In North America, dealers worked to position product in anticipation of a strong fall application season, leading to elevated shipment levels.

In nitrogen, tighter market fundamentals late in the quarter supported a recovery in prices from multi-year lows. This was most evident in urea markets, where seasonally strong demand and lower Chinese exports led to higher prices. Ammonia and UAN prices also strengthened, but remained volatile and well below 2016's third quarter levels, as new expansions began to ramp up, most notably in the US.

Phosphate fertilizer markets witnessed moderate appreciation during the quarter, supported by stronger engagement from India and weather-related supply outages that offset the impact of competition from increased Chinese exports. While prices for industrial products were relatively flat during the quarter, feed prices remained under pressure due to the impact of increased supply from offshore producers, keeping them well below prior-year levels.

Potash
Potash gross margin of $254 million for the third quarter and $627 million for the first nine months of 2017 surpassed the respective totals of $106 million and $317 million generated in 2016, predominantly due to higher prices, reduced per-tonne costs and increased offshore sales volumes.

Sales volumes for the quarter reached a record 2.9 million tonnes, increasing our total for the first nine months to 7.4 million tonnes. In North America, shipments were 10 percent higher than in 2016's record third quarter, while offshore shipments were up 14 percent. The majority of Canpotex's volumes for the quarter were sold to Latin America (30 percent) and Other Asian markets outside of China and India (26 percent), while China and India accounted for 23 percent and 14 percent, respectively.

Our average realized potash price of $179 per tonne in the third quarter exceeded the $150 per tonne realized in the same period last year as prices in all markets continued to strengthen from the lows in 2016.

Manufactured cost of goods sold for the quarter averaged $89 per tonne, down from $106 per tonne in the same period last year, primarily due to increased production and the benefits of optimizing to our lower-cost mines.

Nitrogen
In nitrogen, weaker prices resulted in gross margin of $21 million for the quarter and $186 million for the first nine months, down from $69 million and $306 million, respectively, in 2016. Our Trinidad operations accounted for 60 percent of our quarterly nitrogen gross margin, with our US operations providing the remainder.

Sales volumes of 1.6 million tonnes for the quarter and 4.7 million tonnes for the first nine months were flat compared to the respective periods in 2016.

Our average realized price of $168 per tonne for the third quarter was down from $200 per tonne in the same period last year due to lower realizations for ammonia and nitrogen solutions.

Cost of goods sold for the quarter averaged $157 per tonne, relatively flat compared to third-quarter 2016, as lower natural gas costs in Trinidad were partially offset by increased natural gas costs in the US.

Phosphate
Third-quarter phosphate gross margin of negative $45 million was below the $15 million earned during the same period last year, primarily due to weaker prices and a non-cash impairment charge of $29 million. Negative gross margin of $60 million for the first nine months trailed the $44 million generated in the same period of 2016 when prices for all our phosphate products were higher.

Sales volumes of 0.8 million tonnes for the quarter and 2.0 million tonnes for the first nine months were modest increases from the same periods last year (5 percent and 2 percent, respectively).

Our average realized price for the third quarter was $365 per tonne, below the $385 per tonne realized in the same period last year, largely due to lower prices for feed and industrial products.

Cost of goods sold of $420 per tonne for the quarter exceeded the $366 per tonne in the same period of 2016, mainly due to an impairment of property, plant and equipment at Aurora related to a feed product that we will no longer produce.

Financial
Provincial mining and other taxes for the quarter totaled $47 million, exceeding the $31 million in last year's corresponding period, primarily due to higher potash prices.

Other expenses of $30 million for the third quarter were principally impacted by foreign exchange losses and transaction costs related to the proposed merger with Agrium. This compared to other income of $5 million in 2016's third quarter.

Income tax expense of $22 million for the quarter increased from $2 million in the same period last year predominantly due to discrete tax adjustments related to prior years' provisions.

Potash Market Outlook
We continue to see strong customer engagement in all key potash markets and expect robust demand to continue into 2018. We have maintained our anticipated global shipment range for 2017 at 62-65 million tonnes and, with Canpotex now fully committed for the remainder of the year, we expect this year's demand to eclipse the previous record.

In North America, demand continues to be robust as growers address nutrient needs and capitalize on strong affordability. We expect total shipments to this market to approach the upper end of our 9.3-9.8 million tonnes range.

With its substantial agronomic need and favorable crop economics, we anticipate deliveries to Latin America will remain on pace to surpass those of 2016, with our full-year shipment total unchanged at 12.0-12.5 million tonnes.

In China, we expect nutrient affordability will continue to drive strong consumption. We maintain our 2017 shipment estimate in the range of 15.5-16.5 million tonnes, a potential record for this market.

We continue to see an improving demand environment in India, supported by significant agronomic need, higher minimum support prices and a favorable monsoon. We now expect deliveries for 2017 near the upper end of our guidance range of 4.0-4.5 million tonnes, an increase from 2016 levels.

In Other Asian markets, we expect supportive palm oil prices and improved moisture conditions will support demand for the remainder of the year and are maintaining our estimated shipment range of 9.0-9.5 million tonnes for the full year, above the 2016 total.

Financial Outlook
With greater clarity on potash markets through the balance of the year, we have narrowed our guidance range for potash sales volumes, to 9.1-9.3 million tonnes, and for gross margin, to $750-$800 million.

In nitrogen, we expect markets to remain volatile in the fourth quarter and anticipate full-year gross margin will be significantly weaker than in 2016. In phosphate, we expect challenging market fundamentals will continue to weigh on our realizations. With these factors in mind, and taking into consideration the third-quarter phosphate impairment charge, we have lowered our combined nitrogen and phosphate gross margin range and now estimate $140-$190 million in 2017, trailing last year's combined total.

We now anticipate our effective income tax rate to be in a negative range of 2-4 percent, primarily due to discrete tax adjustments.

We have lowered the upper end of our estimates for provincial mining and other taxes and now expect a range of 19-21 percent of potash gross margin for 2017. Further, we have lowered our range for selling and administrative expenses to $215-$225 million and increased our range for finance costs to $230-$240 million.

We have raised the bottom end of our range for income from equity investments and now expect $180-$190 million, primarily due to the strength of SQM earnings.

Due to the recent strength of the Canadian dollar, we have revised our full-year foreign exchange rate assumption to CDN $1.30 per US dollar.

Based on these factors, we have narrowed our full-year 2017 earnings guidance and now estimate $0.48-$0.54 per share. Merger-related costs are now anticipated to be $0.08 per share, with $0.05 per share expected in the fourth quarter.

All annual guidance numbers - including those noted above - are outlined in the table below.

Potash Corporation of Saskatchewan Inc.
Notes to the Condensed Consolidated Financial Statements
For the Three and Nine Months Ended September 30, 2017
(in millions of US dollars except as otherwise noted)
(unaudited)

1. Significant Accounting Policies

With its subsidiaries, Potash Corporation of Saskatchewan Inc. ("PCS") -- together known as "PotashCorp" or "the company" except to the extent the context otherwise requires -- forms a crop nutrient and related industrial and feed products company. The company's accounting policies are in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS"). The accounting policies and methods of computation used in preparing these unaudited interim condensed consolidated financial statements are consistent with those used in the preparation of the company's 2016 annual consolidated financial statements.

These unaudited interim condensed consolidated financial statements include the accounts of PCS and its subsidiaries; however, they do not include all disclosures normally provided in annual consolidated financial statements and should be read in conjunction with the company's 2016 annual consolidated financial statements. Further, while the financial figures included in this preliminary interim results announcement have been computed in accordance with IFRS applicable to interim periods, this announcement does not contain sufficient information to constitute an interim financial report as that term is defined in International Accounting Standard ("IAS") 34, "Interim Financial Reporting". The company expects to publish an interim financial report that complies with IAS 34 in its Quarterly Report on Form 10-Q in October 2017.

In management's opinion, the unaudited interim condensed consolidated financial statements include all adjustments necessary to present fairly such information. Interim results are not necessarily indicative of the results expected for the fiscal year.

2. Segment Information

The company has three reportable operating segments: potash, nitrogen and phosphate. The accounting policies of the segments are the same as those described in Note 1. Inter-segment sales are made under terms that approximate market value.

Significant items to note include the following:


    --  The actual effective tax rate on ordinary earnings decreased for the
        nine months ended September 30, 2017 compared to the same period last
        year due to different weightings between jurisdictions, most notably a
        decline in the United States partially offset by an increase in Canada.
    --  In the second quarter of 2017, a discrete deferred tax recovery of $68
        was recorded as a result of a Saskatchewan income tax rate decrease.
        This decreased the actual effective tax rate including discrete items
        for the nine months ended September 30, 2017 by 18 percentage points.
    --  In the second quarter of 2016, a $10 discrete non-tax deductible
        impairment of the company's available-for-sale investment in Sinofert
        was recorded. This increased the actual effective tax rate including
        discrete items for the nine months ended September 30, 2016 by one
        percentage point.

6. Share-Based Compensation

Weighted average grant date fair value per unit for stock options and share-settled PSUs granted during 2017 was $4.36 and $19.93, respectively.

Stock Options

Under the LTIP, stock options generally vest and become exercisable on the third anniversary of the grant date, subject to continuous employment or retirement, and have a maximum term of 10 years. The weighted average fair value of stock options granted was estimated as of the date of grant using the Black-Scholes-Merton option-pricing model with the following weighted average assumptions:



    Exercise price per option           $18.71

    Expected annual dividend
     per share                           $0.40

    Expected volatility             29%

    Risk-free interest rate       1.67%

    Expected life of options  5.7 years

Performance Share Units

PSUs granted under the LTIP in 2017 vest based on the achievement of performance metrics, over three years, comprising 1) the relative ranking of the company's total shareholder return compared with a specified peer group using a Monte Carlo simulation and 2) the outcome of the company's cash flow return on investment compared with its weighted average cost of capital. Compensation cost is measured based on 1) the grant date fair value of the units, adjusted for the company's best estimate of the outcome of non-market vesting conditions ((1) )at the end of each period for share-settled PSUs and 2) period-end fair value of the awards for cash-settled PSUs. PSUs granted under the LTIP settle in shares for grantees who are subject to the company's share ownership guidelines and in cash for all other grantees.



    (1) The company's cash flow
     return on investment compared
     with its weighted average cost
     of capital is a non-market
     vesting condition as
     performance is not tied to the
     company's share price or
     relative share price.

7. Proposed Transaction with Agrium Inc.

On September 11, 2016, the company entered into an Arrangement Agreement with Agrium Inc. ("Agrium") pursuant to which the company and Agrium have agreed to combine their businesses (the "Proposed Transaction") in a merger of equals transaction to be implemented by way of a plan of arrangement under the Canada Business Corporations Act. On November 3, 2016, the Proposed Transaction was overwhelmingly approved by shareholders of both companies. On November 7, 2016, the Ontario Superior Court of Justice issued a final order approving the Proposed Transaction. The companies have since received unconditional regulatory clearance in Canada, Brazil and Russia and conditional approval from India requiring PotashCorp's commitment to divest its minority shareholdings in Arab Potash Company ("APC"), ICL and Sociedad Quimica y Minera de Chile S.A. ("SQM") within a period of 18 months from October 18, 2017. The regulatory review and approval process continues in the U.S. and China. Upon the closing of the Proposed Transaction, the new parent company will be named Nutrien Ltd. ("Nutrien"). The Proposed Transaction is currently anticipated to be completed by the end of the fourth quarter of 2017 and is subject to customary closing conditions, including remaining regulatory approvals.

Upon the closing of the Proposed Transaction, the company and Agrium will become indirect, wholly owned subsidiaries of Nutrien. PotashCorp shareholders will own approximately 52 percent of Nutrien, and Agrium shareholders will own approximately 48 percent.

Potash Corporation of Saskatchewan Inc.
Selected Non-IFRS Financial Measures and Reconciliations and Supplemental Information
(in millions of US dollars except percentage amounts)
(unaudited)

The following information is included for convenience only. Generally, a non-IFRS financial measure is a numerical measure of a company's performance, cash flows or financial position that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with IFRS. EBITDA, adjusted EBITDA, adjusted EBITDA margin, cash flow prior to working capital changes and free cash flow are not measures of financial performance (nor do they have standardized meanings) under IFRS. In evaluating these measures, investors should consider that the methodology applied in calculating such measures may differ among companies and analysts.

The company uses both IFRS and certain non-IFRS measures to assess operational performance and as a component of employee remuneration. Management believes these non-IFRS measures provide useful supplemental information to investors in order that they may evaluate PotashCorp's financial performance using the same measures as management. Management believes that, as a result, the investor is afforded greater transparency in assessing the financial performance of the company. These non-IFRS financial measures should not be considered as a substitute for, nor superior to, measures of financial performance prepared in accordance with IFRS.

A. EBITDA, ADJUSTED EBITDA AND ADJUSTED EBITDA MARGIN

Set forth below is a reconciliation of "EBITDA" and "adjusted EBITDA" to net income and "adjusted EBITDA margin" to net income as a percentage of sales, the most directly comparable financial measures calculated and presented in accordance with IFRS.

EBITDA is calculated as net income before finance costs, income tax expense (recovery), and depreciation and amortization. Adjusted EBITDA is calculated as net income before finance costs, income tax expense (recovery), depreciation and amortization, exit costs, termination benefit costs, certain impairment charges and Proposed Transaction costs. PotashCorp uses EBITDA as a supplemental financial measure of its operational performance. Management believes EBITDA and adjusted EBITDA to be important measures as they exclude the effects of items that primarily reflect the impact of long-term investment and financing decisions, rather than the performance of the company's day-to-day operations. As compared to net income according to IFRS, these measures are limited in that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in the company's business, the charges associated with impairments, exit costs, termination costs, or Proposed Transaction costs. Management evaluates such items through other financial measures such as capital expenditures and cash flow provided by operating activities. The company believes that these measurements are useful to measure a company's ability to service debt and to meet other payment obligations or as a valuation measurement.

Adjusted EBITDA margin is calculated as adjusted EBITDA divided by net sales (sales less freight, transportation and distribution). Management believes comparing adjusted EBITDA to net sales earned (net of costs to deliver product) is an important indicator of efficiency. In addition to the limitations given above in using adjusted EBITDA as compared to net income, adjusted EBITDA margin as compared to net income as a percentage of sales is also limited in that freight, transportation and distribution costs are incurred and valued independently of sales; adjusted EBITDA also includes earnings from equity investees whose sales are not included in consolidated sales. Management evaluates these items individually on the consolidated statements of income.

B. CASH FLOW

Set forth below is a reconciliation of "cash flow prior to working capital changes" and "free cash flow" to cash provided by operating activities, the most directly comparable financial measure calculated and presented in accordance with IFRS.

Management uses cash flow prior to working capital changes as a supplemental financial measure in its evaluation of liquidity. Management believes that adjusting principally for the swings in non-cash working capital items due to seasonality or other timing issues assists management in making long-term liquidity assessments. The company also believes that this measurement is useful as a measure of liquidity or as a valuation measurement.

The company uses free cash flow as a supplemental financial measure in its evaluation of liquidity and financial strength. Management believes that adjusting principally for the swings in non-cash operating working capital items due to seasonality or other timing issues, additions to property, plant and equipment, and changes to other assets assists management in the long-term assessment of liquidity and financial strength. Management also believes that this measurement is useful as an indicator of its ability to service its debt, meet other payment obligations and make strategic investments. Readers should be aware that free cash flow does not represent residual cash flow available for discretionary expenditures.
