CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION

This release contains certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to in this Earnings Release as "forward-looking statements") that constitute forward-looking statements. All statements other than statements of historical fact are forward-looking statements. The words ‘‘anticipate'', ‘‘believe'', ‘‘could'', ‘‘expect'', ‘‘should'', ‘‘plan'', ‘‘intend'', ‘‘will'', ‘‘estimate'' and ‘‘potential'', and similar expressions, as they relate to the Company, are intended to identify forward-looking statements.

Statements regarding possible or assumed future results of operations, business strategies, financing plans, competitive position, industry environment, potential growth opportunities, the effects of future regulation and the effects of competition, expected power generation and capital expenditures plan, are examples of forward-looking statements. Forward-looking statements are necessarily based upon a number of factors and assumptions that, while considered reasonable by management, are inherently subject to significant business, economic and competitive uncertainties, and contingencies, which may cause the actual results, performance, or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

The Company assumes no obligation to update forward-looking statements except as required under securities laws. Further information concerning risks and uncertainties associated with these forward-looking statements and the Company's business can be found in the Company's public disclosures filed on EDGAR (www.sec.gov).

Adjusted EBITDA

In this release, Adjusted EBITDA, a non-IFRS financial measure, is defined as net income for the year, plus finance expenses, minus finance income, minus share of the profit of associates, minus depreciation, and amortization, plus income tax expense, plus depreciation and amortization, minus net results of discontinued operations.

Adjusted EBITDA is believed to provide useful supplemental information to investors about the Company and its results. Adjusted EBITDA is among the measures used by the Company's management team to evaluate the financial and operating performance and make day-to-day financial and operating decisions. In addition, Adjusted EBITDA is frequently used by securities analysts, investors, and other parties to evaluate companies in the industry. Adjusted EBITDA is believed to be helpful to investors because it provides additional information about trends in the core operating performance prior to considering the impact of capital structure, depreciation, amortization, and taxation on the results.

Adjusted EBITDA should not be considered in isolation or as a substitute for other measures of financial performance reported in accordance with IFRS. Adjusted EBITDA has limitations as an analytical tool, including:

• Adjusted EBITDA does not reflect changes in, including cash requirements for, working capital needs or contractual commitments;
• Adjusted EBITDA does not reflect the finance expenses, or the cash requirements to service interest or principal payments on indebtedness, or interest income or other finance income;
• Adjusted EBITDA does not reflect income tax expense or the cash requirements to pay income taxes;
• although depreciation and amortization are non-cash charges, the assets being depreciated or amortized often will need to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for these replacements;
• although share of the profit of associates is a non-cash charge, Adjusted EBITDA does not consider the potential collection of dividends; and
• other companies may calculate Adjusted EBITDA differently, limiting its usefulness as a comparative measure.

The Company compensates for the inherent limitations associated with using Adjusted EBITDA through disclosure of these limitations, presentation of the Company's consolidated financial statements in accordance with IFRS and reconciliation of Adjusted EBITDA to the most directly comparable IFRS measure, net income. For a reconciliation of the net income to Adjusted EBITDA, see the tables included in this release.
