Merger Transaction Update

In June 2015, the Company announced that it and its managing member, Niska Gas Storage Management LLC, had entered into a definitive agreement to be acquired by Brookfield Infrastructure and its institutional partners (“Brookfield”).  Brookfield will acquire all of Niska’s outstanding common units for $4.225 per common unit in cash and will acquire the managing member and the incentive distribution rights in Niska. The closing of the transaction is dependent on certain customary conditions being satisfied, including the approval by the California Public Utilities Commission (“CPUC”) of the transfer of control of the Company’s Wild Goose facility to Brookfield.

On June 9, 2016, the CPUC issued a final decision which approved the transfer of control of the Wild Goose facility to Brookfield. The decision is effective immediately. The Company expects that the merger transaction will proceed in accordance with the terms of the merger agreement and that it will close on or prior to July 31, 2016.

Distribution

The Company has agreed not to make earnings distributions until the earlier of the date of closing or termination of the merger transaction. Accordingly, the Company will not pay a distribution to unitholders with respect to the fiscal quarter ended March 31, 2016.

Forward Looking Statements

This press release includes “forward-looking statements” - that is, statements related to future, not past, events. Forward-looking statements are based on current expectations and include any statement that does not directly relate to a current or historical fact. In this context, forward-looking statements often address our expected future business and financial performance, and often contain words such as “anticipate,” “believe,” “intend,” “expect,” “plan,” “will” or other similar words. These forward-looking statements involve certain risks and uncertainties that ultimately may not prove to be accurate. Among these risks and uncertainties are (1) changes in general economic conditions; (2) our level of exposure to the market value of natural gas storage services which could adversely affect our revenues and cash available to make distributions; (3) competitive conditions in our industry; (4) actions taken by third-party operators, processors and transporters; (5) changes in the availability and cost of capital; (6) operating hazards, natural disasters, weather-related delays, casualty losses and other matters beyond our control; (7) the effects of existing and future laws and governmental regulations; (8) the effects of future litigation; and (9) other factors and uncertainties that are unknown or unpredictable could also have a materially adverse effect on future results. For further discussion of risks and uncertainties, you should refer to Niska’s filings with the United States Securities and Exchange Commission. Actual results and future events could differ materially from those anticipated in such statements. Niska undertakes no obligation, and does not intend to update these forward-looking statements to reflect events or circumstances occurring after this press release. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release.  All forward-looking statements are qualified in their entirety by this cautionary statement.

Non-GAAP Financial Measures

Niska uses and discloses the financial measure “Adjusted EBITDA” in this press release. Niska defines Adjusted EBITDA as net earnings (loss) before interest, income taxes, depreciation and amortization, unrealized risk management gains and losses, loss on extinguishment of debt, foreign exchange gains and losses, write-downs of inventory, gains and losses on asset dispositions, non-cash compensation, asset impairments and other income. Niska’s Adjusted EBITDA is not presented in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”). Niska’s management utilizes Adjusted EBITDA as a key performance measure in order to assess:

·                                          the financial performance of Niska’s assets, operations and return on capital without regard to financing methods, capital structure or historical cost basis;

·                                          the ability of Niska’s assets to generate cash sufficient to pay interest on its indebtedness and make distributions to its equity holders;

·                                          repeatable operating performance that is not distorted by non-recurring items or market volatility; and

·                                          the viability of acquisitions and capital expenditure projects.

The GAAP measure most directly comparable to Adjusted EBITDA is net earnings.  For a reconciliation of Adjusted EBITDA to net earnings, please see the schedule provided in the attached pages. Niska believes that investors benefit from having access to the same financial measures used by Niska’s management. Further, Niska believes that these measures are useful to investors because they are one of the bases for comparing Niska’s operating performance with that of other companies with similar operations, although Niska’s measures may not be directly comparable to similar measures used by other companies.
