Elliott Confirms Stake in Japan’s Mitsui OSK

Billionaire Paul Singer's Elliot Management has taken position in the Japanese shipping sector by confirming its stake in Mitsubishi OSK Lines (MOL). The fund, based in Florida, is demanding a massive $3 billion stock buyback. Elliott says the company is sitting on lazy cash and that its current share price does not adequately reflect the underlying value of its global shipping empire.

Elliott Management revealed its stake on Wednesday, instantly putting Mitsui OSK’s leadership on the defensive. The fund thinks the company is trading at a large discount to its book value. Even as it has posted record profits in the recent bump of global shipping, Mitsui OSK has maintained a large cash war that Elliott wants returned to investors.

The market reaction to this deal was immediate, which caused Mitsui OSK’s share price to jump more than 4%. Investors are betting that the company will be compelled to fulfil some of Elliott’s demands. The fund argues that the sale of non-core assets and cross-shareholding would provide more than enough cash to fund a $3 billion buyback.

A sea change for Japanese shippers

This isn’t merely about one company. Japan’s Big three shippers, MOL, NYK and K Line, have all been under scrutiny to do better on capital discipline. The Tokyo Stock Exchange is pressuring companies to enhance their valuations, and Elliott is using those guidelines as a lever to drive Mitsui OSK into action.

Mitsui OSK management is open to dialogue, they have said, but haven’t yet committed to the buyback. Although the company wants to preserve cash for green ship upgrades, Elliott says it can satisfy both loyalties. If a deal isn’t reached, this stand-off could set up a major showdown at the company’s next annual meeting.

Extracting Value from Real Estate

The fund has argued that Mitsui OSK should assess its enormous real estate holdings. In particular, they are urging the company to reconsider relisting a unit known as Daibiru that owns valuable office buildings in central Tokyo. Elliott believes these properties are worth well in excess of current book value.

Outside of real estate, Elliott believes the stock market is underestimating the value of the company’s fleet. Mitsui OSK operates over 900 vessels, including supertankers and cargo ships. The activist fund contends the market “materially undervalues” this entire business. Elliott is seeking to narrow the gap between the low price of its stock and the high value of a company’s actual ships and buildings.
