Please refer to "Definitions and Non-GAAP Financial Measures" and the Appendices to this release for definitions of these terms and reconciliations of these non-GAAP financial measures as used in this release to the most directly comparable financial measures under United States generally accepted accounting principles (GAAP).

GAAP net (loss) income and adjusted net (loss) income for the second quarter of 2017 compared to the second quarter of 2016 were primarily affected by lower spot tanker rates and a decrease in the Company's fleet size. GAAP net (loss) income was also affected by a non-cash write-down of the Company's investment in TIL and lower unrealized gains on derivative instruments partially offset by lower losses on vessel sales and lower revenues as a result of the redeliveries of 10 time chartered-in vessels during 2016 and the first quarter of 2017.

CEO Commentary

“The proposed merger with Tanker Investments Ltd. is strategically very important for Teekay Tankers,” stated Kevin Mackay, Teekay Tankers’ President and Chief Executive Officer. “The 18-vessel Tanker Investments Ltd. fleet will provide Teekay Tankers with greater scale to continue servicing its customers, while also allowing us to renew our fleet on an opportunistic basis at the right point of the cycle. We believe this merger is in the best interests of Teekay Tankers’ shareholders as it is immediately accretive to the Company’s earnings per share, reduces our average fleet age by one year, and reduces our cash break-even rate.  Importantly, the merger is expected to increase Teekay Tankers’ liquidity and reduce our financial leverage.” 

Mr. Mackay continued “The agreed share-for-share exchange ratio for the proposed merger was based on the underlying fair market value of each respective fleet earlier this year and since that time, asset values have increased by approximately 5 percent, as validated by independent transactions in the tanker sale and purchase market.  As a result, the merger remains a compelling transaction for Teekay Tankers.”

In reference to the current spot tanker market, Mr. Mackay added, “The tanker market faced challenging headwinds in the second quarter of 2017.  Seasonal weakness and increasing tanker deliveries, combined with lower OPEC oil production, have all contributed to weak tanker rates which we expect will continue until later this year when typical seasonal factors are expected to push rates higher. Looking ahead to 2018, we expect that a significant slowdown in tanker fleet growth coupled with better oil market fundamentals will lead to a recovery in freight rates, from the second half of 2018.”

Summary of Recent Developments

Strategic Merger

On May 31, 2017, Teekay Tankers agreed to acquire all of the remaining issued and outstanding shares of TIL in a share-for-share merger at an exchange ratio of 3.30 shares of Teekay Tankers Class A common stock for each share of TIL common stock. TIL owns a modern fleet of 10 Suezmax tankers, 6 Aframax tankers and 2 LR2 product tankers with an average age of 7.3 years. The merger will further strengthen the Company's balance sheet and liquidity position, and is expected to be accretive to earnings per share, reduce the Company's cash breakeven and result in approximately $3 million of annual cost savings. Closing of the merger, which remains subject to various conditions, including, among others, approval from both TIL shareholders and TNK Class A common shareholders, is expected to occur in the fourth quarter of 2017.

The Company currently holds an approximate 11 percent interest in TIL and accounts for this investment using the equity method. When accounting for the merger at the date of closing, GAAP will require the Company to treat its existing equity investment in TIL as being disposed of at its fair value and concurrently repurchased at such fair value, which will be included as part of the cost of the acquisition of the 100 percent controlling interest in TIL on the closing date. Although the merger has not yet concluded, the agreement that was reached between the parties in the second quarter of 2017 resulted in Teekay Tankers being required to compare the carrying value of its investment to its fair value as at June 30, 2017. As a result, the Company recognized a non-cash impairment charge of $28.1 million during the quarter ended June 30, 2017 related to its equity investment in TIL, based on the best available indication of fair value at June 30, 2017, which was the TIL share price on that date.

Acquisition of Remaining 50 Percent Interest of Teekay Tanker Operations Ltd. (TTOL)

Prior to May 31, 2017, the Company owned 50 percent of TTOL. On May 31, 2017, the Company completed the acquisition from Teekay Corporation (Teekay) of the remaining 50 percent interest in TTOL for $39.1 million, which includes $13.2 million for assumed working capital, in exchange for the Company's issuance to Teekay of approximately 13.8 million shares of Class B common stock as well as payment of $13.2 million in cash, resulting in Teekay Tankers owning 100 percent of TTOL and consolidating its results. Periods prior to May 31, 2017 have been recast to include 100 percent of TTOL results on a consolidated basis in accordance with Common Control accounting as required under GAAP. The impact of this recasting is referred to herein as the Entities under Common Control and such amounts are summarized for the respective periods in Appendix A to this release.

Completed Sale-Leaseback Financing Transaction

In July 2017, Teekay Tankers completed a $153 million sale-leaseback financing transaction relating to four of its modern Suezmax tankers. The transaction is structured as a 12-year bareboat charter at an average rate of approximately $11,100 per day with attractive purchase options for all four vessels throughout the lease term after year three. The transaction strengthens the Company’s balance sheet and increases the Company’s liquidity position by approximately $30 million. As a result of the transaction, Teekay Tankers expects to recognize an accounting write-down in the third quarter of 2017 of approximately $20 million per vessel.

Completed Sale of an Older Aframax Tanker

In June 2017, Teekay Tankers completed the sale of a 1999-built Aframax tanker, the Kyeema Spirit, to a third party for proceeds of approximately $7.5 million.

Secured Additional Fixed-Rate Charter

In May 2017, Teekay Tankers entered into a time charter-out contract for one Aframax tanker at a rate of approximately $16,000 per day and a firm period of 18 months, which charter contract commenced in late-May 2017.

Tanker Market

Crude tanker spot rates softened during the second quarter of 2017 due to the combined impact of lower OPEC oil production, high tanker fleet growth and normal seasonal weakness. Rates have continued to decline at the start of the third quarter of 2017, in what is normally the weakest part of the year for tanker rates.

OPEC supply cuts continue to have a negative impact on crude tanker demand, with OPEC crude oil production averaging 32.1 million barrels per day (mb/d) through the first half of 2017 compared with production of 33.2 mb/d at the end of 2016. The majority of these supply cuts have come from the Middle East nations, led by Saudi Arabia.

Some of the spot rate weakness has been offset by an increase in exports from key mid-size tanker load regions. US crude oil exports have averaged 750 thousand barrels per day (kb/d) through the first half of 2017 compared with average exports of 485 kb/d in 2016, with oil increasingly moving long-haul to destinations such as India and China. Production has also been recovering in recent weeks in Nigeria and Libya, both of which are exempt from OPEC supply cuts. Libyan production reportedly reached 1 mb/d as of July 2017, which if confirmed would be the highest production level since mid-2013. Nigerian crude production reached 1.6 mb/d in June 2017, the highest since April 2016. Taken together, these developments should be positive for mid-size tanker demand in the Atlantic basin.

In addition to these positive trade fundamentals, global oil demand growth remains robust with forecast growth of approximately 1.4 mb/d in 2017 and a further 1.4 mb/d in 2018, according to the International Energy Agency (IEA). This is an upward revision since last quarter due to higher than expected demand growth in the non-OECD areas.

Despite these positive demand factors, high tanker fleet growth continues to significantly challenge the tanker market and has led to a decrease in tanker fleet utilization and tanker rates through the first half of the year. The global tanker fleet grew by 19.4 million deadweight tons (mdwt), or 3.5 percent in the first half of 2017, due to a heavy delivery schedule for large crude tankers and a continued lack of scrapping. For 2017 as a whole, the Company forecasts tanker fleet growth of approximately 5.5 per cent, similar to 2016 levels. However, the Company anticipates much lower fleet growth in 2018 as the orderbook rolls off, while an increase in tanker scrapping is expected as a number of vessels reach their fourth special survey date. New regulations may also increase scrapping in the medium-term, although the IMO’s implementation date for installation of ballast water treatment systems has been deferred from September 2017 to September 2019.

Overall, the Company expects weak tanker rates to persist during the remainder of the third quarter before a normal seasonal uptick in the fourth quarter. Looking ahead to 2018, the Company expects that a significant slowdown in tanker fleet growth coupled with better oil market fundamentals will lead to a recovery in freight rates, particularly from the second half of 2018.

Definitions and Non-GAAP Financial Measures

This release includes various financial measures that are non-GAAP financial measures as defined under the rules of the U.S. Securities and Exchange Commission. These non-GAAP financial measures, which include Adjusted Net (Loss) Income, Free Cash Flow, Net Revenues and Cash Flow from Vessel Operations, are intended to provide additional information and should not be considered a substitute for measures of performance prepared in accordance with GAAP. In addition, these measures do not have standardized meanings, and may not be comparable to similar measures presented by other companies. The Company believes that certain investors use this information to evaluate the Company’s financial performance, as does management.

Consolidated Financial Measures

Adjusted net (loss) income excludes items of income or loss from GAAP net income that are typically excluded by securities analysts in their published estimates of the Company’s financial results. The Company believes that certain investors use this information to evaluate the Company’s financial performance, as does management. Please refer to Appendix A of this release for a reconciliation of this non-GAAP financial measure to net (loss) income, the most directly comparable GAAP measure reflected in the Company’s consolidated financial statements.

Free cash flow (FCF) represents net income, plus depreciation and amortization, unrealized losses from derivatives, certain non-cash items, FCF from equity accounted investments, loss on sale of vessel, and any write-offs or other non-recurring items, less unrealized gains from derivatives, equity income from the equity accounted investments, gain on sale of vessel and certain other non-cash items. The Company includes FCF from equity accounted investments as a component of its FCF. FCF from the equity accounted investments represents the Company’s proportionate share of FCF from its equity-accounted investments. The Company does not control its equity-accounted investments, and as a result, the Company does not have the unilateral ability to determine whether the cash generated by its equity-accounted investments is retained within the entity in which the Company holds the equity accounted investment or distributed to the Company and other owners. In addition, the Company does not control the timing of such distributions to the Company and other owners. Consequently, readers are cautioned when using FCF as a liquidity measure as the amount contributed from FCF from the equity accounted investments may not be available to the Company in the periods such free cash flow is generated by the equity accounted investments. FCF is a non-GAAP financial measure used by certain investors and management to evaluate the Company’s financial and operating performance and to assess the Company’s ability to generate cash sufficient to repay debt, pay dividends and undertake capital and dry dock expenditures. Please refer to Appendix B to this release for a reconciliation of this non-GAAP financial measure to the most directly comparable GAAP financial measure reflected in the Company’s consolidated financial statements.

Net revenues represent revenues less voyage expenses. Because the amount of voyage expenses the Company incurs for a particular charter depends upon the type of the charter, the Company uses net revenues to improve the comparability between periods of reported revenues that are generated by the different types of charters and contracts. The Company principally uses net revenues, a non-GAAP financial measure, because the Company believes it provides more meaningful information about the deployment of the Company's vessels and their performance than does revenues, the most directly comparable financial measure under GAAP.

Cash flow from vessel operations (CFVO) represents income from vessel operations before depreciation and amortization expense, amortization of in-process revenue contracts, vessel write-downs, and gains or losses on the sale of vessels and equipment. CFVO - Consolidated represents CFVO from vessels that are consolidated on the Company’s financial statements. CFVO - Equity Investments represents the Company’s proportionate share of CFVO from its equity-accounted vessels and other investments. The Company does not control the equity-accounted vessels and investments, and as a result, the Company does not have the unilateral ability to determine whether the cash generated by its equity accounted vessels and other investments is retained within the entity in which the Company holds the equity accounted investment or distributed to the Company and other owners. In addition, the Company does not control the timing of such distributions to the Company and other owners. Consequently, readers are cautioned when using total CFVO as a liquidity measure as the amount contributed from CFVO - Equity Investments may not be available to the Company in the periods such CFVO is generated by its equity-accounted vessels and other investments. CFVO is a non-GAAP financial measure used by certain investors and management to measure the operational financial performance of companies. Please refer to Appendices C of this release for reconciliations of these non-GAAP financial measures to income from vessel operations and income from vessel operations of equity accounted investments,

respectively, the most directly comparable GAAP measures reflected in the Company’s consolidated financial statements.

Entities under common control represent a transfer of a business between entities under common control. As a result, Teekay Tankers consolidated financial statements prior to the date the interests in these entities were actually acquired by the Company are retroactively adjusted to include the results of these entities during the periods they were under common control of Teekay and had begun operations.

(1) Prior to May 31, 2017, the Company owned 50 percent of Teekay Tanker Operations Ltd. (or TTOL) and accounted for this investment using the equity method of accounting. The Company acquired the remaining 50 percent of TTOL on May 31, 2017 from Teekay, resulting in the Company owning 100 percent of TTOL and consolidating its results. Periods prior to May 31, 2017 have been recast to include 100 percent of TTOL results on a consolidated basis in accordance with Common Control accounting as required under GAAP. The impact of this recasting is referred to herein as the Entities under Common Control and such amounts are summarized for the respective periods in Appendix A. The amounts included in this release related to the Entities under Common Control are preliminary, and will be finalized for inclusion in the Company's Quarterly Report on Form 6-K for the three and six months ended June 30, 2017. Any revisions to the preliminary Entities under Common Control figures are expected only to impact the accounting for the periods prior to May 31, 2017, the date the remaining 50 percent of TTOL was acquired by the Company, and therefore will have no effect on the adjusted net income attributable to the shareholders or free cash flow of the Company for any period, including the second quarter of 2017.

(2) Voyage charter revenues include revenues earned from full service lightering activities. Voyage expenses include certain costs associated with full service lightering activities, which include: short-term in-charter expenses, bunker fuel expenses and other port expenses totaling $15.0 million, $20.4 million and $6.2 million for the three months ended June 30, 2017, March 31, 2017 and June 30, 2016, respectively.

(3) Other revenues include lightering support and LNG services revenue, and pool management fee and commission revenues earned from TTOL.

(4) In March 2017, the Company agreed to sell anAframax tanker, the Kyeema Spirit, for proceeds of $7.5 million, resulting in the recognition of a write-down of $2.6 million in the first quarter of 2017. The sale completed in June 2017 and the Company recognized a loss on the sale of vessel of $0.2 million. In February 2017, the Company delivered the Yamuna Spirit, a Suezmax tanker, to its new owner and the Company recognized a loss on sale of the vessel of $1.5 million in the first quarter of 2017.

(5) Includes realized losses relating to interest rate swaps that relate to amounts actually paid by the Company of $0.3 million, $0.4 million and $1.3 million for the three months ended June 30, 2017, March 31, 2017 and June 30, 2016, respectively. Also includes realized gains relating to a time-charter swap agreement of $0.4 million, $0.7 million and $0.1 million for the three months ended June 30, 2017, March 31, 2017 and June 30, 2016, respectively.

(6) Included in equity (loss) income are the Company’s 50 percent interest in the High-Q joint venture (High-Q), which owns one VLCC tanker, its 50 percent interest in Gemini Tankers L.L.C., and its proportionate 11.3 percent share of earnings from its investment in TIL. The Company also recognized an impairment of $28.1 million on its investment in TIL, as explained in (i) below.

Components of equity (loss) income are detailed in the table below:

		Three Months Ended					Six Months Ended
		June 30,		March 31,	June 30,		June 30,		June 30,
		2017		2017	2016		2017		2016
High-Q Joint Venture		756		793	2,202		1,549		2,531

Total equity (loss) income		(28,027	)	1,127	3,615		(26,900	)	5,849

(i) As part of the accounting for the TIL merger, GAAP treats the Company's existing equity investment in TIL as being disposed of at its existing fair value and concurrently repurchased at such fair value, which is included in the cost of the acquisition of the 100% controlling interest in TIL. As a result of the expected merger between Teekay Tankers and TIL, it was determined that recovery of the carrying value of the Company's investment in TIL prior to closing of the merger would be unlikely. Consequently, a non-cash impairment of $28.1 million was required under GAAP to be recognized in the three months ended June 30, 2017 based on the difference between the carrying value of the investment at June 30, 2017 and its fair value based on the TIL share price on that date.
