What is Behind Auburn National Bancorporation Inc’s (AUBN) Superior ROE?

Becky Mayes

With an ROE of 9.31%, Auburn National Bancorporation Inc (NASDAQ:AUBN) outpaced its own industry which delivered a less exciting 8.92% over the past year. Superficially, this looks great since we know that AUBN has generated big profits with little equity capital; however, ROE doesn’t tell us how much AUBN has borrowed in debt. In this article, we’ll closely examine some factors like financial leverage to evaluate the sustainability of AUBN’s ROE. View our latest analysis for Auburn National Bancorporation

What you must know about ROE

Return on Equity (ROE) weighs AUBN’s profit against the level of its shareholders’ equity. For example, if AUBN invests $1 in the form of equity, it will generate $0.09 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 AUBN, which is 11.27%. This means AUBN’s returns actually do not cover its own cost of equity, with a discrepancy of -1.95%. This isn’t sustainable as it implies, very simply, that the company pays more for its capital than what it generates in return. ROE can be split up into three useful 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 AUBN is with its cost management. Asset turnover shows how much revenue AUBN can generate with its current asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable AUBN’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt AUBN currently has. The debt-to-equity ratio currently stands at a low 8.02%, meaning the above-average ROE is due to its capacity to produce profit growth without a huge debt burden.

What this means for you:

Are you a shareholder? AUBN’s above-industry ROE is noteworthy, but it was not high enough to cover its own cost of equity. However, investors shouldn’t despair since ROE is not inflated by excessive debt, which means AUBN still has room to improve shareholder returns by raising debt to fund new investments.
