Sales Volumes and Revenues

During the first three months of 2006, sales revenues were up a strong 35.5% compared with the same period last year (the increase is more than 46% when the data are restated on a comparable scope of consolidation basis), rising from 1,801 million euros in 2005 to 2,441 million euros this year. The electric power operations and the hydrocarbons operations grew by 59.3% and 36.1%, respectively.

Both businesses benefited from significantly higher average sales prices, due mainly to an increase in raw material costs. In addition, the electric power operations reported a sharp gain in unit sales, which were up 28.3% to 16,558 GWh (12,901 GWh in 2005), due mainly to steady growth in the deregulated market (+46.5%). Edison's expanded significantly its penetration of this market thanks to the full availability of the Candela, Altomonte and Piacenza power plants.

Unit sales by the hydrocarbons operations increased by 1.1% in the first quarter of the year, rising from 4,366 million cubic meters in 2005 to 4,414 million cubic meters in 2006. Specifically, sales to thermoelectric power plants, which reflected the start of production at new facilities, were up 19.4% to 2,088 million cubic meters (1,748 million cubic meters in the first three months of 2005). At the same time, sales to residential users decreased from 1,902 million cubic meters in the first three months of 2005 to 1,778 million cubic meters this year, as demand was curtailed by the limited supply of natural gas caused by the "natural gas emergency."

EBITDA

EBITDA grew by 7.4%, rising from 311 million euros in the first quarter of 2005 to 334 million euros in the same period this year. This improvement was made possibly by a strong performance by the electric power operations, which, thanks to higher unit sales and the optimization of their portfolio of production facilities, were able to more than offset the impact of the expiration of CIP-6 incentives for some of the Group's power plants, a decrease in hydroelectric output caused by a reduction in the availability of water resources, the arising charges in connection with CO2 emission requirements and a deterioration of the operating results reported by the hydrocarbons operations. The operating performance of the hydrocarbons operations was adversely affected by a compression of its sales margins caused by a narrowing of the price-cost spread, attributable to changes in the manner by which prices are indexed to the benchmark fuel markets, and a conservative decision to set aside a provision to cover costs that will arise from the enactment of Resolution No. 298/05 (which Edison is contesting), by which the Electric Power and Natural Gas Authority updated customer gas rates for the first quarter of 2006.

Edison, basing on the changed regulating scenario and on the inflation dynamics in the international energy markets, started actions with its gas suppliers aimed at modifying current contractual conditions.

EBIT

EBIT grew to 187 million euros, compared with 171 million euros in the first quarter of 2005 (+9.4%).

Net Profit

The Group's interest in net profit was 67 million euros, down 32% from 99 million euros in the first quarter of 2005, due to the recognition of a provision (32 million euros) set aside conservatively to cover a fine recently imposed by the European Commission on the "old" Montedison for alleged actions in restraint of competition in the hydrogen peroxide and sodium perborate markets by Ausimont, a former subsidiary that was sold to Solvay in 2002.

Indebtedness

At March 31, 2006, the Group's net borrowings totaled 4,916 million euros, down from 4,939 million euros in the first quarter of 2005 (4,878 million euros December 31, 2005).

Outlook for the Balance of 2006

The full availability of the power plants that were commissioned in 2005 and the startup of the new Torviscosa power plant in the second half of the year should help the Group's industrial operations report improved results for all of 2006.
