Revenue growth

A company’s long-term revenue performance is one signal of its overall quality. Any business can have short-term success, but a top-tier one grows for years.

With $761.4 million in revenue over the past 12 months, Portillo's is a small restaurant chain, which sometimes brings disadvantages compared to larger competitors benefiting from better brand awareness and economies of scale. On the positive side, it can grow faster because it has more room to build new restaurants.

Portillo’s revenue grew at a decent 7.2% compounded annual growth rate over the last seven years as it opened new restaurants and expanded its reach.

This quarter, Portillo's grew its revenue by 7% year on year, and its $194.1 million in revenue was in line with Wall Street’s consensus estimates.

Looking ahead, sell-side analysts expect revenue to grow 4.5% over the next 12 months, according to S&P, a slight deceleration versus the last seven years. This underwhelming projection suggests its menu offerings will see some demand headwinds.

Restaurant performance

Number of restaurants

A restaurant chain’s total number of dining locations often determines how much revenue it can generate.

Portillo's operated 109 locations in the latest quarter. It has opened new restaurants at a rapid pace over the last two years, averaging 11.5% annual growth, much faster than the broader restaurant sector. This gives it a chance to scale into a mid-sized business over time.

When a chain opens new restaurants, it usually means it’s investing for growth because there’s healthy demand for its meals and there are markets where its concepts have few or no locations.

Same-store sales

A company’s restaurant base only paints one part of the picture. When demand is high, it makes sense to open more. But when demand is low, it’s prudent to close some locations and use the money in other ways. Same-store sales gives us insight into this topic because it measures organic growth at restaurants open for at least a year.

Portillo’s demand within its existing dining locations has barely increased over the last two years as its same-store sales were flat. Portillo's should consider improving its foot traffic and efficiency before expanding its restaurant base.

In the latest quarter, Portillo’s same-store sales rose 1.4% year on year. This marked a turnaround from historical levels, showing the business is regaining momentum.

Key takeaways from Portillo’s Q3 results

Portillo's had a solid quarter, but one earnings result doesn’t necessarily make the stock a buy. When making that decision, it’s important to consider its valuation, business quality and what has happened in the latest quarter. Read the full research report here for more on Portillo's (it’s free).
