Shares inDrax(LSE: DRX) slumped by 28% yesterday after George Osborne announced that he was making some key changes to the UKs Climate Change Levy.
As part of these changes,renewable energy companies will nolonger be exempt from the levy.Currently,taxis not paid on renewable electricity generated under renewable source contracts, regardless of whether it is generated in the UK or abroad.
Drax is in the process of converting the UKs largest coal power station into a plant designed to burn wood pellets, which are considered a renewable fuel.
So, the company stands to lose a sizable amount of income following this change.
Latest setback
Unfortunately, this is just the latest in a string of setbacks for Drax. Indeed, during the past few years, the company has issued a series of profit warnings, net profit has fallen by 31% since 2010 and the groups long-term debt has tripled.
But whats more concerning is the fact that Draxs return on assets has collapsed during the past five years.
Falling returns
Return on invested capital is a key metric for measuring business efficiency. The figure gives a great indicationof how well a company is using its money to generate returns. And the most efficient businesses, with the highest ROIC figures, are usually the best long-term investments.
For example,National Grids(LSE: NG)ROIC has remained steady at around 7% per year since 2011. Over the same period, shareholder equity has expanded by 33%, and book value per share has grown at a compound annual growth rate of 13.5% per annum since 2010.
In other words, National Grid has been creating a significant amount of value for investors. Its little wonder that the companys shares have produced a total return of 15.8% per annum since 2010.
Over the same period, Draxs ROIC has slumped from a high of 29.4% to a low of 3.9%.Book value per share has increased at a compound annual growth rate of around 2% per annum since 2011.
So, it should come as no surprise that Draxs shares have produced a total return of -0.6% per annum for the past five years.
Unlikely to improve
Draxs fortunes are unlikely to improve anytime soon. Estimates vary, but figures suggest that due to the tax changes announced yesterday, Draxs earnings before interest, tax, amortization and depreciation could be lower by 30m this year, and 60m during 2016.
Analysts were expecting the company to report EBITDA of 193m for 2015. After factoring in the reduction of 30m, Draxs EBITDA is now set to fall to 163m this year, 29% below last years reported figure. On the other hand, National Grids EBITDA is set to march steadily higher by around 3.5% per annum for the next three years.
National Grid currently supports a dividend yield of 5.3%, and the payout is covered one-and-a-half times by earnings per share. City analysts expect Drax to cut its dividend payout by 40% this year, which will leave the company supporting a yield of 2%.
