What These Ratios Tell Us About GlaxoSmithKline plc
Before I decide whether to buy a company's shares, I always like to look at two core financial ratios -- return on equity and net gearing.
These two ratios provide an indication of how successful a company is at generating profits using shareholders' funds and debt, and they have a strong influence on dividend payments and share price growth.
Today, I'm going to take a look at pharmaceutical heavyweight GlaxoSmithKline (LSE: GSK) (NYSE: GSK.US), to see how attractive it looks on these two measures.
Return on equity
The return a company generates on its shareholders' funds is known as return on equity, or ROE. Return on equity can be calculated by dividing a company's annual earnings by its equity (ie, the difference between its total assets and its total liabilities) and is expressed as a percentage.
GlaxoSmithKline has delivered some stunning ROE figures last five years, as this table shows:
These figures appear very impressive, but there is a sting in the tail, as I'll explain in a moment.
What about debt?
A key weakness of ROE is that it doesn't show how much debt a company is using to boost its returns. My preferred way of measuring a company's debt is by looking at its net gearing -- the ratio of net debt to equity.
In the table below, I've listed Glaxo's net gearing and ROE alongside those of its peers, Pfizer and AstraZeneca.
While Glaxo's ROE is higher than both of its peers, there's no doubt that based on ROE and net gearing alone, AstraZeneca looks far more appealing then debt-laden Glaxo.
Glaxo's net debt increased by £5.0bn in 2012, thanks mainly to its £2bn acquisition of Human Genome Sciences, and the £1.9bn it paid the U.S. government to settle various U.S. federal government investigations.
Is GlaxoSmithKline a buy?
Glaxo is currently in the middle of a program to cut costs, focus investment on products with high growth potential, and dispose of certain non-core or mature products.
As a shareholder, I'm cautiously optimistic that this strategy will result in improved cash generation and debt reduction over the next few years. Without this, Glaxo's 4.8% prospective yield could become harder for the firm to afford.
Despite these risks, I still rate Glaxo as a buy: the world's population is getting richer and living longer, and that means that demand for Glaxo's products will continue to grow.
