*Attributable to shareholders of Boralex for continuing operations

The 2013 first-quarter results confirmed the dominant and strategic role of the wind and hydroelectric power segments as Boralex's main performance drivers. Wind power segment output, revenues and EBITDA grew by 10.8%, 14.3% and 17.1%, respectively, over the same quarter of 2012. With a profit margin on the order of 84%, the wind power segment had a 55% share of aggregate EBITDA before the corporate segment.
This strategy has proven beneficial, as the contribution from the St-Patrick wind farm almost completely offset the decline in production resulting primarily from the shutdown of operations at the Kingsey Falls thermal power station.
"In line with its development strategy, Boralex is building on the strengths of its wind and hydroelectric power segments to continue generating growth in Canada and France. In light of its available financial resources, including $122 million in cash, Boralex has the means to fund the equity portion of wind power projects totalling approximately 100 MW in additional capacity on top of the projects currently being developed," said President and CEO Patrick Lemaire. "Boralex's objectives are to achieve an installed capacity of approximately 1,000 MW and double its annual EBITDA to exceed $200 million by the end of 2016," added Mr. Lemaire.
Building on 286 MW of wind power assets currently in operation, Boralex will add
528 MW under long-term power sales contracts in the coming years, of which the Corporation's net interest amounts to 334 MW. In France, there are 88 MW in projects currently being developed with commissioning set between late 2013 and summer 2014. In Canada, 246 MW will be commissioned between Q4 2013 and Q4 2015, including Phase 1 of the Seigneurie de Beaupré Wind Farms, one of Canada's largest wind power sites, to be commissioned in December 2013. Incidentally, construction work at the site is on schedule and on budget.
However, in the hydroelectric power segment, despite a slight drop in production output owing in particular to less favourable water conditions in the Northeastern United States than in 2012, Boralex posts increases in revenues and EBITDA of 0.9% and 6.0%, respectively, in addition to generating a solid EBITDA margin of 80.0%. The decline in production in this segment, relative to their historical averages, was almost completely offset by a favourable price effect experienced in the NYSIO open market by the four U.S. power stations not covered by power sales contracts.
On the hydroelectric development front, construction is proceeding according to plan at the Jamie Creek power station in British Colombia, Canada, with commissioning set for
2014. The Corporation's growth outlook for this segment in Ontario and British Columbia remains good.
Excluding the Kingsey Falls power station's shutdown, the thermal power segment recorded increases in production and EBITDA of 18% and $1.2 million, respectively, fuelled by improved performance at the Senneterre power station in Canada.

Segmented Information

The Corporation's power stations are grouped into four distinct operating segments-wind, hydroelectric, thermal and solar power. The Corporation operates under one reportable segment: power generation. The classification of these segments is based on the different cost structures relating to each of the four types of power stations. The same accounting rules are used for segmented information as for the consolidated accounts.

The operating segments are presented according to the same criteria used to prepare the internal report submitted to the segment leader who allocates resources and assesses operating segment performance. The President and Chief Executive Officer is considered the segment leader, who assesses segment performance based on production of electricity, revenues from energy sales and EBITDA.

EBITDA does not have a standardized meaning under IFRS; accordingly, it may not be comparable to similarly named measures used by other companies. Investors should not view EBITDA as an alternative measure to, for example, net earnings, or as a measure of operating results, which are IFRS measures.

EBITDA is reconciled to the most comparable IFRS measure, namely, net earnings attributable to shareholders of Boralex, in the following table:

Cash flows from operations are equal to net cash flows related to operating activities before change in non-cash items related to operating activities. Management uses this measure to assess cash flows generated by the Corporation's operations and its capacity to finance its expansion through those funds. In light of the seasonal nature of the Corporation's operations and development activities, changes in non- cash items can vary considerably. In addition, development activities result in significant changes in Trade and other payables during the construction period, as well as an initial injection of working capital at project start-up. Accordingly, the Corporation considers it more representative not to integrate changes in non-cash items in this performance measure.

Investors should not consider cash flows from operations as an alternative measure to cash flows related to operating activities, which is an IFRS measure.

Cash flows from operations are reconciled to the most comparable IFRS measure, namely, net cash flows related to operating activities, in the following table:
