Last week's profit announcement from Tigo Energy, Inc. (NASDAQ:TYGO) was underwhelming for investors, despite headline numbers being robust. We did some digging and found some worrying underlying problems.

A Closer Look At Tigo Energy'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. The accrual ratio subtracts the FCF from the profit for a given period, and divides the result by the average operating assets of the company over that time. The ratio shows us how much a company's profit exceeds its FCF.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. While having an accrual ratio above zero is of little concern, we do think it's worth noting when a company has a relatively high accrual ratio. That's because some academic studies have suggested that high accruals ratios tend to lead to lower profit or less profit growth.

For the year to March 2026, Tigo Energy had an accrual ratio of -0.43. That implies it has very good cash conversion, and that its earnings in the last year actually significantly understate its free cash flow. In fact, it had free cash flow of US$15m in the last year, which was a lot more than its statutory profit of US$3.37m. Given that Tigo Energy had negative free cash flow in the prior corresponding period, the trailing twelve month resul of US$15m would seem to be a step in the right direction. Having said that, there is more to consider. We must also consider the impact of unusual items on statutory profit (and thus the accrual ratio), as well as note the ramifications of the company issuing new shares.

To understand the value of a company's earnings growth, it is imperative to consider any dilution of shareholders' interests. As it happens, Tigo Energy issued 22% more new shares over the last year. Therefore, each share now receives a smaller portion of profit. To talk about net income, without noticing earnings per share, is to be distracted by the big numbers while ignoring the smaller numbers that talk to per share value.

A Look At The Impact Of Tigo Energy's Dilution On Its Earnings Per Share (EPS)

Three years ago, Tigo Energy lost money. And even focusing only on the last twelve months, we don't have a meaningful growth rate because it made a loss a year ago, too. What we do know is that while it's great to see a profit over the last twelve months, that profit would have been better, on a per share basis, if the company hadn't needed to issue shares. Therefore, the dilution is having a noteworthy influence on shareholder returns.

If Tigo Energy's EPS can grow over time then that drastically improves the chances of the share price moving in the same direction. But on the other hand, we'd be far less excited to learn profit (but not EPS) was improving. For the ordinary retail shareholder, EPS is a great measure to check your hypothetical "share" of the company's profit.

The Impact Of Unusual Items On Profit

While the accrual ratio might bode well, we also note that Tigo Energy's profit was boosted by unusual items worth US$14m in the last twelve months. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And, after all, that's exactly what the accounting terminology implies. Tigo Energy had a rather significant contribution from unusual items relative to its profit to March 2026. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.

Our Take On Tigo Energy's Profit Performance

In conclusion, Tigo Energy's accrual ratio suggests its earnings are well backed by cash but its boost from unusual items is probably not going to be repeated consistently. Meanwhile, the dilution was a negative for shareholders. Based on these factors, we think that Tigo Energy's statutory profits probably make it seem better than it is on an underlying level.
