TMK ANNOUNCES ESTIMATED 4Q 2017 FINANCIAL RESULTS FOR IPSCO TUBULARS

Forward-looking statements: The following contains forward-looking statements concerning future events. These statements are based on current information and assumptions of TMK management concerning known and unknown risks and uncertainties.

PAO TMK ("TMK"), one of the world's leading producers of tubular products for the oil and gas industry, announces estimates of select unaudited financial results of IPSCO Tubulars Inc. ("IPSCO") for the fourth quarter of 2017. Except as noted below, the estimates were calculated in accordance with U.S. generally accepted accounting principles ("GAAP").

We estimate that IPSCO's revenue will be within a range of $313.0 million to $332.0 million for the fourth quarter of 2017. We also estimate that IPSCO's net income will be within a range of $20.7 million to $29.2 million for the fourth quarter of 2017.

In addition, we estimate that IPSCO's Adjusted EBITDA and Adjusted EBITDA Margin will be within ranges of $38.2 million to $46.3 million and 12.2% to 13.9% for the fourth quarter of 2017, respectively. IPSCO defines Adjusted EBITDA as its net income, before finance costs and finance income, income tax expense and benefits, depreciation and amortization, foreign exchange gains and losses, impairment charges of non-current assets, gains and losses on disposal of property, plant and equipment, gains and losses on changes in fair value of financial instruments and other non-recurring or unusual items. IPSCO defines Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of revenues.

The estimated financial information included in this release is presented in accordance with GAAP, with the exception of Adjusted EBITDA and Adjusted EBITDA Margin, which are non-GAAP measures. The estimated financial information reflects our estimates based solely upon information available to us as of the date of this release and is the responsibility of management. The estimated financial results presented above are not a comprehensive statement of IPSCO's financial results for the fourth quarter of 2017. In addition, the estimated financial results presented above have not been audited, reviewed, or compiled by our independent registered public accounting firm. The estimated financial results presented above are subject to the completion of our financial closing procedures, which have not yet been completed. IPSCO's actual results for the fourth quarter of 2017 are not yet available and may differ materially from these estimates. Therefore, you should not place undue reliance upon these estimated financial results. For instance, during the course of the preparation of the respective financial statements and related notes, additional items that would require material adjustments to be made to the estimated financial results presented above may be identified. There can be no assurance that these estimates will be realized, and estimates are subject to risks and uncertainties, many of which are not within our control. Accordingly, the revenue, net income (loss), Adjusted EBITDA and Adjusted EBITDA Margin for any particular period may not be indicative of future results.
