Suburban Propane Partners (SPH) has drawn fresh attention after reporting second quarter fiscal 2026 earnings, with net income holding near last year despite lower revenue and continued progress in renewable natural gas projects.

Suburban Propane Partners’ share price has been relatively steady over recent months. The current price of $19.61 sits alongside a year to date share price return of 4.92%, while longer term total shareholder returns of 9.48% over one year and more than 7x over five years point to momentum that has built over time rather than faded after the latest earnings and renewable natural gas updates.

With earnings holding up, renewable projects advancing and the unit price already up strongly over five years, the key question now is simple: is Suburban Propane Partners still undervalued, or is the market already pricing in future growth?

Price-to-Earnings of 9.8x: Is it justified?

On a P/E of 9.8x, Suburban Propane Partners trades at a lower earnings multiple than both the global gas utilities industry average of 14.3x and a peer average of 14.7x. This suggests the current $19.61 unit price sits below where many similar companies are valued.

The P/E ratio compares the current unit price to earnings per unit, so it effectively shows how much investors are paying today for each dollar of earnings. For a mature utilities business with $1.39b in revenue, $133.35m in net income and relatively steady cash generation, this is a common reference point because earnings tend to be a central driver of returns in the sector.

Here, the gap is clear. The P/E of 9.8x sits well below both the industry and peer averages, and also below an estimated fair P/E of 13.8x. That fair ratio suggests a level the multiple could move toward if the market eventually prices Suburban Propane Partners more in line with companies that have similar characteristics.

Result: Price-to-Earnings of 9.8x (UNDERVALUED)

However, you also need to weigh softer recent returns over 90 days and 7 days, and an annual decline in net income growth, which could challenge any undervaluation thesis.

Another view: cash flow based fair value

The earlier P/E work points to a unit price that looks low compared with peers, but our DCF model paints an even starker picture. With Suburban Propane Partners at $19.61 and an estimated future cash flow value of $29.59, the units appear to trade at about a one third discount. Is this a mispricing or a sign that the cash flow assumptions are too optimistic?
