Mitsui (TSE:8031): Reassessing Valuation After Strategic Shift Away from Blue Water Alliance Joint Venture

Simply Wall St
It is not every day that investors in Mitsui (TSE:8031) see a major joint venture come to an end, but that is exactly what just happened with the company’s recent decision alongside Olin Corporation. The two companies have mutually agreed to dissolve their Blue Water Alliance JV, LLP (BWA) by year’s end. This marks a significant shift in Mitsui’s approach within the EDC value chain. This move could reshape how Mitsui operates in this segment, hinting at a pivot toward more flexible partnerships and potentially unlocking new opportunities or risks for shareholders. Over the past year, Mitsui’s stock has delivered a gain of 26%, accelerating to a 27% advance in the past 3 months, which signals growing momentum well above its own year-to-date returns. This follows several years of substantial growth, and the company continues to post steady annual revenue and net income increases. The timing of the BWA exit, coming in the wake of these strong results and ongoing corporate changes, suggests the market is sizing up how Mitsui will navigate the evolving landscape. With the end of the joint venture on the table and a rising share price behind it, the big question now is whether Mitsui is undervalued after this structural change or if the market has already factored in all the growth potential ahead.

Most Popular Narrative: 2.6% Undervalued

The prevailing narrative views Mitsui as modestly undervalued, with price targets just above current trading levels. Analysts are factoring in a mix of opportunity and risk as the business pivots toward the energy transition and broad portfolio changes.

Mitsui's ongoing investments in LNG, low-carbon ammonia, and related infrastructure projects (such as Blue Point and Ruwais LNG) position the company to capture growth from the increasing global demand for cleaner energy sources. This is likely to boost revenue and long-term earnings stability as the energy transition accelerates.
