NextDecade is working on large liquefied natural gas and carbon capture projects, yet its share price has pulled back sharply in recent weeks. Does that recent slide leave the stock looking undervalued or still expensive on today’s numbers?

Most Popular Narrative: 34.7% Undervalued

Based on the most followed narrative, NextDecade's fair value of $9.40 sits well above the latest close at $6.14, which puts a spotlight on the assumptions behind that gap.

Early cargo sales of over 175 trillion BTUs at expected margins of more than US$3 per MMBtu and the company’s projection that approximately 3,800 TBtus of early LNG volumes could generate US$1.2b to US$2b of distributable cash flow provide a defined path to use near term cash inflows to reduce term loans and corporate level leverage, which can support future net income.

Want to see what sits behind that potential cash flow surge for NextDecade? The narrative focuses on steep revenue ramp up, margin shifts and a valuation multiple that is well below typical sector levels. It examines how those moving parts combine to reach a higher fair value than today’s share price.

The most widely followed narrative uses a discount rate of 11.59% and links the $9.40 fair value to very large forecast revenue growth and a future profit margin that aligns with broader US oil and gas peers. It also applies a moderate P/E multiple to those future earnings rather than a premium, despite the scale of the Rio Grande LNG project and the projected uplift in distributable cash flow as additional liquefaction trains and ownership step ups come into play.

Result: Fair Value of $9.40 (UNDERVALUED)

However, the bullish narrative around NextDecade can quickly shift if Rio Grande LNG faces construction delays or if high project debt keeps leverage above the 3 to 3.5x target.
