Calix, Inc.'s (NYSE:CALX) earnings announcement last week was disappointing for investors, despite the decent profit numbers. We did some digging and actually think they are being unnecessarily pessimistic.

A Closer Look At Calix's Earnings

Many investors haven't heard of the accrual ratio from cashflow, but it is actually a useful measure of how well a company's profit is backed up by free cash flow (FCF) during a given period. To get the accrual ratio we first subtract FCF from profit for a period, and then divide that number by the average operating assets for the period. This ratio tells us how much of a company's profit is not backed by free cashflow.

Therefore, it's actually considered a good thing when a company has a negative accrual ratio, but a bad thing if its accrual ratio is positive. That is not intended to imply we should worry about a positive accrual ratio, but it's worth noting where the accrual ratio is rather high. That's because some academic studies have suggested that high accruals ratios tend to lead to lower profit or less profit growth.

Over the twelve months to December 2025, Calix recorded an accrual ratio of -0.20. Therefore, its statutory earnings were very significantly less than its free cashflow. To wit, it produced free cash flow of US$116m during the period, dwarfing its reported profit of US$17.9m. Calix's free cash flow improved over the last year, which is generally good to see.

Our Take On Calix's Profit Performance

Happily for shareholders, Calix produced plenty of free cash flow to back up its statutory profit numbers.

And it's also positive that the company showed enough improvement to book a profit this year, after losing money last year. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. While it's really important to consider how well a company's statutory earnings represent its true earnings power, it's also worth taking a look at what analysts are forecasting for the future.
