Is Infinis Energy PLC A Better Income Buy Than SSE PLC, Centrica PLC & National Grid plc?

Renewable energy generator Infinis Energy (LSE: INFI) currently offers a prospective dividend yield of 10%.

Conventional utilities such as SSE (LSE: SSE) Centrica (LSE: CNA) and National Grid (LSE: NG) (NYSE: NGG.US) ‘only’ yield between 4.5% and 5.5%. Should I dump these lumbering giants from my portfolio and invest in Infinis?

Not so fast

A quick calculation tells me that the 18.7p cash dividend Infinis is forecast to pay this year would cost the firm £56m. That’s 30% more than the £43.3m Infinis is expected to report in post-tax profits.

It was a similar story last year, when Infinis paid 18.3p per share, or £55m, to shareholders, despite reporting earnings of just 6.9p per share.

In fairness, last year’s £55m dividend was almost covered by free cash flow, which totalled £53m. However, this was only because of a one-off £20m gain from the sale of the company’s hydro-electric assets. Free cash flow from continuing operations was only about £33m.

A big IPO clue

Infinis floated on the London Stock Exchange in November 2013. Prior to this it was owned by Guy Hands’ well-known private equity firm, Terra Firma, which remains the controlling shareholder with a 70% stake.

Private equity firms are well-known for selling at the top. The firm’s shares have performed poorly since joining the stock market, falling by 30% from an initial price of 269p to today’s price of 188p.

I suspect that the generous dividend is the result of pressure from Terra Firma, which will want to extract as much cash as possible from Infinis while it remains a controlling shareholder.

3 reasons not to buy

The firm’s 2014 results highlighted three factors that have discouraged me from investing in Infinis.

1. Oil prices

Infinis warned that the fall in oil prices “has resulted in lower gas and wholesale power prices”.

This has not been a big issue so far, but Infinis says that if oil prices remain at current levels for a number of years, “this will have an adverse impact on the performance of the Company”.

I believe oil prices are likely to remain low.

2. Terra Firm wants out

Secondly, Terra Firma has said it would like to sell its remaining 70% shareholding.

Such a large sale could well take place at a discount to the current market price, depressing the share price further.

3. Political risk

Infinis’s profits are heavily dependent on government subsidies for renewable energy. These are likely to change over time, possibly unpredictably. This has already happened in the solar market, for example.

Dividend cuts

Ultimately, I think Infinis’s dividend is too aggressive to be safe. The firm might manage to maintain this level of payout for some years, but it might not. It’s not something I’d be comfortable with in my income portfolio.

In contrast, Centrica’s recent 30% dividend cut was disappointing for shareholders but should now put the firm on a safe footing for future payouts, which will be based on post-tax operating cash flow.

Similarly, both SSE and National Grid have managed to maintain their policy dividend growth in-line with RPI inflation. Both have dividend cover of about 1.25, and remain attractive as income buys, in my view.

It's also no coincidence that Infinis Energy was not the utility selected by the Motley Fool's top analysts for their lifetime income portfolio, "5 Shares To Retire On".

Instead, the Fool's experts chose just one of the other utilities I've discussed in this article.
