What is Behind Halma plc’s (LON:HLMA) Superior ROE?

With an ROE of 18.99%, Halma plc (LSE:HLMA) outpaced its own industry which delivered a less exciting 10.49% over the past year. On the surface, this looks fantastic since we know that HLMA 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 HLMA’s ROE. View our latest analysis for Halma

What you must know about ROE

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 £0.19 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 Halma, which is 8.30%. This means Halma returns enough to cover its own cost of equity, with a buffer of 10.69%. This sustainable practice implies that the company 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

Basically, profit margin measures how much of revenue trickles down into earnings which illustrates how efficient the business is with its cost management. Asset turnover reveals how much revenue can be generated from Halma’s asset base. The most interesting ratio, and reflective of sustainability of its ROE, is financial leverage. Since ROE can be artificially increased through excessive borrowing, we should check Halma’s historic debt-to-equity ratio. Currently the debt-to-equity ratio stands at a low 32.59%, which means its above-average ROE is driven by its ability to grow its profit without a significant debt burden.

While ROE is a relatively simple calculation, it can be broken down into different ratios, each telling a different story about the strengths and weaknesses of a company. Halma’s ROE is impressive relative to the industry average and also covers its cost of equity. Its high ROE is not likely to be driven by high debt. Therefore, investors may have more confidence in the sustainability of this level of returns going forward. Although ROE can be a useful metric, it is only a small part of diligent research.
