Targa Resources’ recent flurry of major project announcements is helping to offset softness in its share price, which has trended down nearly 12% year-to-date. Even so, the story for long-term holders remains compelling, with a 1-year total shareholder return in positive territory and a remarkable 931% total return over five years. This signals momentum and strong value creation for patient investors.

Most Popular Narrative: 21.4% Undervalued

Compared to Targa Resources' last close of $161.30, the narrative consensus sets fair value at $205.30. This highlights a wide gap between market price and long-term earnings potential. This difference raises the stakes for investors closely watching the company’s ambitious growth initiatives as valuation narratives diverge from recent share performance.

Substantial investment in integrated export infrastructure, including the expansion and debottlenecking of LPG export facilities and new fractionation trains, directly leverages rising international and petrochemical-sector demand for U.S. NGLs. This creates long-term opportunities to enhance utilization and operating leverage, which should support higher earnings and margins.

Another View: Multiples Tell a Different Story

While the narrative consensus sees Targa Resources as undervalued, the company’s price-to-earnings ratio of 22.8x stands well above both the US Oil and Gas industry average (13.1x) and its own fair ratio of 19.2x. This suggests the market is already pricing in significant optimism, potentially raising the risk for new buyers. Could investors be assuming too much upside?
