Did Columbia Banking System Inc (NASDAQ:COLB) Create Value For Investors Over The Past Year?

Julian Fleming

Columbia Banking System Inc (NASDAQ:COLB) delivered a less impressive 5.79% ROE over the past year, compared to the 8.20% return generated by its industry. An investor may attribute an inferior ROE to a relatively inefficient performance, and whilst this can often be the case, knowing the nuts and bolts of the ROE calculation may change that perspective and give you a deeper insight into COLB’s past performance. I will take you through how metrics such as financial leverage impact ROE which may affect the overall sustainability of COLB’s returns. Check out our latest analysis for Columbia Banking System

Breaking down ROE — the mother of all ratios

Return on Equity (ROE) weighs Columbia Banking System’s profit against the level of its shareholders’ equity. It essentially shows how much the company can generate in earnings given the amount of equity it has raised. Generally speaking, a higher ROE is preferred; however, there are other factors we must also consider before making any conclusions.

Return on Equity = Net Profit ÷ Shareholders Equity

ROE is measured against cost of equity in order to determine the efficiency of Columbia Banking System’s equity capital deployed. Its cost of equity is 9.83%. This means Columbia Banking System’s returns actually do not cover its own cost of equity, with a discrepancy of -4.05%. 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

Essentially, profit margin shows how much money the company makes after paying for all its expenses. Asset turnover reveals how much revenue can be generated from Columbia Banking System’s 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 financial leverage can artificially inflate ROE, we need to look at how much debt Columbia Banking System currently has. At 7.24%, Columbia Banking System’s debt-to-equity ratio appears low and indicates that Columbia Banking System still has room to increase leverage and grow its profits.

Next Steps:

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. Columbia Banking System exhibits a weak ROE against its peers, as well as insufficient levels to cover its own cost of equity this year. However, ROE is not likely to be inflated by excessive debt funding, giving shareholders more conviction in the sustainability of returns, which has headroom to increase further. Although ROE can be a useful metric, it is only a small part of diligent research.
