Most Popular Narrative: 13% Overvalued

Despite analysts raising their fair value estimate to ¥2,801, Inpex's last close at ¥3,170 suggests the market is now pricing in a premium. This valuation sets the stage for debate over which assumptions are driving the latest narrative.

The current valuation appears to assume that INPEX's large-scale LNG and upstream expansion projects (notably Ichthys expansion and Abadi FID) will execute on time and on budget, unlocking substantial future earnings and cash flows. This is despite industry risks such as execution delays, cost overruns, and commodity price volatility that could significantly compress net margins if not managed well.

Read the complete narrative.

Curious what bold growth projections and high-stakes project assumptions are packed into this fair value? The market's narrative leans heavily on big expansion bets. Can this momentum hold if the future turns out differently? Dive in to discover which numbers and uncertainties are powering this elevated price call.

Result: Fair Value of ¥2,801 (OVERVALUED)

However, stronger-than-expected Asian LNG demand or successful expansion projects could quickly disrupt this view of overvaluation and restore market optimism.
