If you're looking at a mature business that's past the growth phase, what are some of the underlying trends that pop up? More often than not, we'll see a declining return on capital employed (ROCE) and a declining amount of capital employed. This reveals that the company isn't compounding shareholder wealth because returns are falling and its net asset base is shrinking. In light of that, from a first glance at Accuray (NASDAQ:ARAY), we've spotted some signs that it could be struggling, so let's investigate.
Just to clarify if you're unsure, ROCE is a metric for evaluating how much pre-tax income (in percentage terms) a company earns on the capital invested in its business. To calculate this metric for Accuray, this is the formula:
Return on Capital Employed = Earnings Before Interest and Tax (EBIT) ÷ (Total Assets - Current Liabilities)
0.0056 = US$1.5m ÷ (US$457m - US$195m) (Based on the trailing twelve months to September 2025).
Therefore, Accuray has an ROCE of 0.6%. Ultimately, that's a low return and it under-performs the Medical Equipment industry average of 11%.

We are a bit worried about the trend of returns on capital at Accuray. About five years ago, returns on capital were 7.5%, however they're now substantially lower than that as we saw above. And on the capital employed front, the business is utilizing roughly the same amount of capital as it was back then. Since returns are falling and the business has the same amount of assets employed, this can suggest it's a mature business that hasn't had much growth in the last five years. If these trends continue, we wouldn't expect Accuray to turn into a multi-bagger.
On a side note, Accuray's current liabilities are still rather high at 43% of total assets. This can bring about some risks because the company is basically operating with a rather large reliance on its suppliers or other sorts of short-term creditors. While it's not necessarily a bad thing, it can be beneficial if this ratio is lower.
In summary, it's unfortunate that Accuray is generating lower returns from the same amount of capital. This could explain why the stock has sunk a total of 80% in the last five years. That being the case, unless the underlying trends revert to a more positive trajectory, we'd consider looking elsewhere.
