Nanosonics (ASX:NAN) has had a rough month with its share price down 8.8%. However, stock prices are usually driven by a company's financials over the long term, which in this case look pretty respectable. Particularly, we will be paying attention to Nanosonics' ROE today.
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
How To Calculate Return On Equity?
The formula for ROEis:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Nanosonics is:
9.8% = AU$21m ÷ AU$210m (Based on the trailing twelve months to June 2025).
The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every A$1 worth of equity, the company was able to earn A$0.10 in profit.

What Is The Relationship Between ROE And Earnings Growth?
We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.
