Despite posting healthy earnings, Lam Research Corporation's (NASDAQ:LRCX ) stock has been quite weak. Along with the solid headline numbers, we think that investors have some reasons for optimism.

Examining Cashflow Against Lam Research'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. 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. You could think of the accrual ratio from cashflow as the 'non-FCF profit ratio'.

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. 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. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.

For the year to September 2024, Lam Research had an accrual ratio of -0.10. That indicates that its free cash flow was a fair bit more than its statutory profit. In fact, it had free cash flow of US$4.8b in the last year, which was a lot more than its statutory profit of US$4.06b. Lam Research's free cash flow improved over the last year, which is generally good to see.

Our Take On Lam Research's Profit Performance

Lam Research's accrual ratio is solid, and indicates strong free cash flow, as we discussed, above. Based on this observation, we consider it likely that Lam Research's statutory profit actually understates its earnings potential! And the EPS is up 5.7% over the last twelve months. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider.
