GMO: Unlocking the Value Trapped in a Tangled Web

TOKYO — GMO Internet Group (TSE: 9449) closed on October 26 at a market cap of $1.97bn. Its stakes in its own listed subsidiaries were worth $2.86bn at the same close. Buy the parent and you pay 69 cents on the dollar for a basket of listed shares, with the unlisted businesses thrown in. Days after GMO Internet (4784) shut down every server over a breach, that discount is no longer a curiosity. It is the trade.

All amounts in this note are in US dollars, converted from yen at ¥157.45 = US$1, the mid-market rate on October 26, 2026. Market caps are at the October 26 close. Subsidiary results are each company's latest full fiscal year. The company writes its English name as "GMO internet group, Inc." in its filings; this note capitalizes it as GMO Internet Group for readability.

Our previous note, GMO's listed stakes are worth 1.45x the parent. The hack may force the unwind, laid out the structure. This one asks what an outside investor should do with it.

A payments company with "Internet" in its name

The nine listed subsidiaries together: $379mn. Parent, consolidated: $376mn. Payment Gateway's fiscal year ends in September; the others in December.

The group calls itself an internet-infrastructure company. Two financial subsidiaries earn 80% of its operating profit. The nine listed subsidiaries together earned $379mn, more than the consolidated $376mn: everything else the parent does is a net cost.

The leakage sits one line down. The nine reported $261mn of net income. The parent's look-through share is $133mn. The other 49% belongs to minorities. And the leak is widest at the best asset: Payment Gateway earns 53% of the group's profit, has grown operating profit from $129mn to $199mn in two years, and is held at 40.7%, the lowest stake of the nine. Sixty cents of every dollar the best business earns go to someone else.

The buy-in that cannot be paid for

Sell every other listed holding and the proceeds cover about half of what Payment Gateway's minorities are worth today. The parent's entire market cap is smaller than the cheque.

That leaves paper. A share exchange would put the parent's stock, at a 31% discount to its own holdings, up against Payment Gateway stock at a full payments multiple. The ratio would transfer value from the parent's shareholders to Payment Gateway's. It would also need two-thirds of the votes at Payment Gateway's meeting, where the parent holds 40.7%, from holders being asked to swap a payments company for a conglomerate.

Turn it upside down

Let Payment Gateway absorb the parent. Payment Gateway, at a market cap of $3.94bn, issues shares to the parent's shareholders and takes in everything the parent owns. The parent's 40.7% of Payment Gateway is cancelled as treasury stock. Payment Gateway's holders acquire Financial Holdings, GMO Internet, GlobalSign and the rest at the 31% discount the market already applies. The parent's holders receive Payment Gateway stock, and the discount vanishes because the holding no longer exists.

Tax points the same way. Under Japan's reorganisation rules a share-for-share merger defers the gain. Selling the Payment Gateway stake, or distributing it in kind, does not: the parent would pay tax on appreciation accumulated since it took control of Payment Gateway in 2004, before any shareholder saw a dollar. The one route that is both affordable and tax-efficient is the one in which the parent, not the subsidiary, ceases to exist.

Sell the broker at the top

Financial Holdings need not wait. Its operating profit went $92mn, $57mn, $101mn over three years; a foreign-exchange and crypto broker earns what the market gives it, and 2025 was a peak. The parent's 65.9% is worth $0.52bn at market, roughly $0.67bn with a control premium. Put into a buy-back, that retires a third of the parent's shares at a 31% discount to the assets behind them. It creates value on its own, before anyone argues about Payment Gateway.

Why none of this has happened

Masatoshi Kumagai holds 41.65% of the parent. Inside the web that stake carries the parent's resolutions and, through the parent, the board of a payments company in which he owns 17% by look-through: a pyramid in which control exceeds ownership. After a full combination he would own about 18% of the survivor. That 18% would be worth more than his 41.65% is today, because the discount would be gone. But 18% is a stake two funds can outvote on any special resolution. The web is worth less than its parts to every shareholder except one, and that one has the votes.

Where to sit

The position is the parent. Buying the parent is buying Payment Gateway at a 31% discount with Financial Holdings and GMO Internet attached. If nothing happens, the holding is covered 1.45 times by listed assets and Financial Holdings' cycle turns again. If the parent sells Financial Holdings and buys back stock, the discount narrows. If Payment Gateway absorbs the parent, it closes.

A position in Payment Gateway itself is insurance: it matters only if the parent tries a cheap share exchange, where a Payment Gateway holder has the veto. The small subsidiaries are a footnote. Japan's tender-offer rules give every holder the same price as the controlling seller, so a seat in GMO Pepabo (3633) or GMO Media (6180) collects the premium whichever way the parent moves, in sizes that matter only to a small fund.

One rule covers all of it: build the positions first, open the conversation second. Once the parent has told you its plans for Payment Gateway or Financial Holdings, you are an insider in both.

None of this value is hidden. It is listed, priced every day, and on offer at a 31% discount, held in place by one shareholder's preference for control over wealth. That preference will not change on its own. It changes when enough of the other 58% of the parent's register asks for the same thing at the same time. The breach took away the record that kept the question from being asked. The trade is to buy the parent and ask it.

Subsidiary figures are each company's latest full fiscal year (Payment Gateway and GMO Financial Gate to September 2025, GMO Prime Strategy to November 2025, the rest to December 2025) and are not adjusted for fiscal year-end differences or consolidation. Net income totals exclude a $7mn non-cash gain on negative goodwill that GMO TECH Holdings (415A) booked on its 2025 integration. Minority-stake values and premiums are at October 26 prices; the 30% premium is an assumption, not a forecast.
