Is Big Yellow Group Plc’s (LON:BYG) ROE Of 13.26% Sustainable?

Casey Hall

Big Yellow Group Plc (LSE:BYG) delivered an ROE of 13.26% over the past 12 months, which is an impressive feat relative to its industry average of 11.57% during the same period. On the surface, this looks fantastic since we know that BYG has made large profits from little equity capital; however, ROE doesn’t tell us if management have borrowed heavily to make this happen. In this article, we’ll closely examine some factors like financial leverage to evaluate the sustainability of BYG’s ROE. Check out our latest analysis for Big Yellow Group

Breaking down ROE — the mother of all ratios

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. For example, if the company invests £1 in the form of equity, it will generate £0.13 in earnings from this. In most cases, a higher ROE is preferred; however, there are many other factors we must consider prior to making any investment decisions.

Return on Equity = Net Profit ÷ Shareholders Equity

ROE is assessed against cost of equity, which is measured using the Capital Asset Pricing Model (CAPM) – but let’s not dive into the details of that today. For now, let’s just look at the cost of equity number for Big Yellow Group, which is 8.30%. Since Big Yellow Group’s return covers its cost in excess of 4.96%, its use of equity capital is efficient and likely to be sustainable. Simply put, Big Yellow Group pays less for its capital than what it generates in return. ROE can be dissected into three distinct ratios: net profit margin, asset turnover, and financial leverage. This is called the Dupont Formula:

Dupont Formula

ROE = profit margin × asset turnover × financial leverage

ROE = (annual net profit ÷ sales) × (sales ÷ assets) × (assets ÷ shareholders’ equity)

ROE = annual net profit ÷ shareholders’ equity

The first component is profit margin, which measures how much of sales is retained after the company pays for all its expenses. The other component, asset turnover, illustrates how much revenue Big Yellow Group can make from its asset base. Finally, financial leverage will be our main focus today. It shows how much of assets are funded by equity and can show how sustainable the company’s capital structure is. Since ROE can be inflated by excessive debt, we need to examine Big Yellow Group’s debt-to-equity level. The debt-to-equity ratio currently stands at a low 35.01%, meaning the above-average ROE is due to its capacity to produce profit growth without a huge debt burden.
