Examining Cashflow Against PureTech Health's Earnings

One key financial ratio used to measure how well a company converts its profit to free cash flow (FCF) is the accrual ratio. In plain english, this ratio subtracts FCF from net profit, and divides that number by the company's average operating assets over that period. The ratio shows us how much a company's profit exceeds its FCF.

That means a negative accrual ratio is a good thing, because it shows that the company is bringing in more free cash flow than its profit would suggest. 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 2024, PureTech Health recorded an accrual ratio of 0.89. As a general rule, that bodes poorly for future profitability. To wit, the company did not generate one whit of free cashflow in that time. Over the last year it actually had negative free cash flow of US$134m, in contrast to the aforementioned profit of US$53.5m. We also note that PureTech Health's free cash flow was actually negative last year as well, so we could understand if shareholders were bothered by its outflow of US$134m. However, that's not all there is to consider. We can see that unusual items have impacted its statutory profit, and therefore the accrual ratio.

How Do Unusual Items Influence Profit?

Given the accrual ratio, it's not overly surprising that PureTech Health's profit was boosted by unusual items worth US$163m in the last twelve months. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. Which is hardly surprising, given the name. We can see that PureTech Health's positive unusual items were quite significant relative to its profit in the year to December 2024. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.
