Our Analysis
This project delivers an 18% after-tax IRR, landing in the bottom quartile of the 16 lithium peers we track. While it clears the typical 15% project-finance hurdle, single-asset lithium developers often require 20%+ to compensate for jurisdictional and execution risk—this return sits below that threshold. The after-tax NPV of €1.02B is roughly 14.6x the company's market cap, a gap that cuts two ways: it could signal the market has not priced in the asset's value, or it may reflect skepticism about financing, permitting, or lithium price assumptions. The study's price deck is a key sensitivity to watch, as returns are highly dependent on it.
Initial capex of €750M, at 74% of NPV, is moderately capital-intensive and represents a material funding burden relative to the company's small market cap. The single most important risk is financing: raising this quantum of capital for a bottom-quartile IRR project in a single-asset junior will likely require significant dilution or a partner, both of which compress equity value.
