A Closer Look At AIXTRON's Earnings

In high finance, the key ratio used to measure how well a company converts reported profits into free cash flow (FCF) is the accrual ratio (from cashflow). In plain english, this ratio subtracts FCF from net profit, and divides that number by the company's average operating assets over that period. This ratio tells us how much of a company's profit is not backed by free cashflow.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. While it's not a problem to have a positive accrual ratio, indicating a certain level of non-cash profits, a high accrual ratio is arguably a bad thing, because it indicates paper profits are not matched by cash flow. To quote a 2014 paper by Lewellen and Resutek, "firms with higher accruals tend to be less profitable in the future".

Over the twelve months to September 2026, AIXTRON recorded an accrual ratio of -0.49. Therefore, its statutory earnings were very significantly less than its free cashflow. Indeed, in the last twelve months it reported free cash flow of €360m, well over the €80.5m it reported in profit. AIXTRON shareholders are no doubt pleased that free cash flow improved over the last twelve months.
