Ribbon Communications Inc.'s (NASDAQ:RBBN) robust recent earnings didn't do much to move the stock. We think this is due to investors looking beyond the statutory profits and being concerned with what they see.

The Impact Of Unusual Items On Profit

To properly understand Ribbon Communications' profit results, we need to consider the US$21m expense attributed to unusual items. While deductions due to unusual items are disappointing in the first instance, there is a silver lining. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And that's hardly a surprise given these line items are considered unusual. Ribbon Communications took a rather significant hit from unusual items in the year to March 2026. As a result, we can surmise that the unusual items made its statutory profit significantly weaker than it would otherwise be.

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that Ribbon Communications received a tax benefit of US$90m. This is of course a bit out of the ordinary, given it is more common for companies to be paying tax than receiving tax benefits! Of course, prima facie it's great to receive a tax benefit. And since it previously lost money, it may well simply indicate the realisation of past tax losses. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On Ribbon Communications' Profit Performance

In the last year Ribbon Communications received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. Having said that, it also had a unusual item reducing its profit. Given the contrasting considerations, we don't have a strong view as to whether Ribbon Communications's profits are an apt reflection of its underlying potential for profit. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved.
