Company Overview

Best known for its Grown in Idaho brand, Lamb Weston (NYSE: LW) produces and distributes potato products such as frozen french fries and mashed potatoes.

Revenue Growth

A company’s long-term sales performance is one signal of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years.

With $6.52 billion in revenue over the past 12 months, Lamb Weston is one of the larger consumer staples companies and benefits from a well-known brand that influences purchasing decisions.

As you can see below, Lamb Weston’s sales grew at a decent 10.7% compounded annual growth rate over the last three years as consumers bought more of its products.

This quarter, Lamb Weston reported modest year-on-year revenue growth of 2.9% but beat Wall Street’s estimates by 5.2%.

Looking ahead, sell-side analysts expect revenue to remain flat over the next 12 months, a deceleration versus the last three years. This projection doesn't excite us and indicates its products will face some demand challenges.

Volume Growth

Revenue growth can be broken down into changes in price and volume (the number of units sold). While both are important, volume is the lifeblood of a successful staples business as there’s a ceiling to what consumers will pay for everyday goods; they can always trade down to non-branded products if the branded versions are too expensive.

To analyze whether Lamb Weston generated its growth (or lack thereof) from changes in price or volume, we can compare its volume growth to its organic revenue growth, which excludes non-fundamental impacts on company financials like mergers and currency fluctuations.

Over the last two years, Lamb Weston’s average quarterly volume growth was a healthy 2.6%. In the context of its flat organic sales, however, we can deduce its increased volume has come at the expense of some price cuts and discounting. Lower selling prices, regardless of a company’s quality, are a headwind to higher profit margins.

In Lamb Weston’s Q1 2026, sales volumes jumped 7% year on year. This result was an acceleration from its historical levels, certainly a positive signal.
