Coincheck valued shares at $4 for 3iQ, then sold KDDI stock at $2.28

Coincheck Group used two sharply different share values in transactions completed three months apart. For its March acquisition of Canadian digital-asset manager 3iQ, the merger agreement assigned Coincheck shares a contractual value of $4 each. In June, Japanese telecom group KDDI subscribed for 28,536,516 newly issued Coincheck shares at $2.28 each, paying approximately $65.063 million. The second price was 43% below the first. The contrast is real, but it is not a clean 43% collapse in one market valuation: the transactions transferred different assets, occurred under different conditions and carried different governance and commercial rights.[1][2][4][5]

The useful investigation is therefore not to choose one number as Coincheck’s “true” value. It is to reconstruct what each number actually priced. The 3iQ transaction was a common-control acquisition from Monex Group and minority holders, paid primarily with Coincheck equity under a negotiated merger formula. The KDDI transaction was a cash subscription by a new strategic investor, accompanied by a business alliance, referral arrangements and a board nomination right. Accounting treatment, contractual share value, cash issue price and voting influence are four distinct measurements.[1][2][5][6]

The 3iQ share value was a transaction formula

Coincheck agreed to acquire 99.8% of 3iQ. Its filings identify an agreed 3iQ value of $111.840 million and a contractual Coincheck share value of $4. Monex received 27,149,684 Coincheck shares and minority sellers received 761,161, for 27,910,845 shares in total. Multiplying those shares by $4 produces $111.643 million—close to, but not exactly the stated 3iQ value. The remaining difference can reflect the precise transaction mechanics, rounding, cash or other adjustments disclosed elsewhere in the merger documents. It should not be erased by forcing the two totals to reconcile beyond the available rows.[1][3]

The accounting value provides a third number. Coincheck recorded consideration of ¥17.423 billion for the 3iQ acquisition under common-control accounting. Because Monex controlled both Coincheck and 3iQ, the combination was treated as a transaction among entities under common control rather than an arm’s-length purchase that resets every asset and liability to a conventional acquisition-date fair value. The difference between the contractual transaction framework and the predecessor carrying values enters merger reserve or equity accounting. Converting the yen figure into dollars at a chosen exchange rate and presenting it as a third purchase price would mix accounting basis, currency date and transaction definition.[1][3]

The annual report also shows why the acquired business cannot be judged from the headline consideration alone. For the period included after closing, 3iQ contributed ¥191 million of revenue and an ¥11 million net loss. That is roughly one month of post-acquisition activity, not a full-year earnings run rate and not evidence that the acquisition was worth only a multiple of one month’s revenue. Asset-management economics depend on assets under management, fee rates, market levels, product flows and costs over a longer period. The filing gives the first recognised slice, not a complete valuation case.[1]

KDDI paid cash but also bought a route into Coincheck’s ecosystem

KDDI’s $2.28 subscription brought cash directly into Coincheck. The alliance also contemplated customer referrals and revenue sharing across the companies’ services. KDDI obtained the right to nominate a non-executive director, subject to the governing documents and shareholder process. Those elements can affect the negotiated price: a strategic investor may value commercial access and governance differently from a seller accepting shares in a merger. Conversely, the lower issue price can dilute existing shareholders more heavily per dollar raised than a $4 issue would.[5][2][4]

At $2.28 per share, raising approximately $65.063 million required 28.537 million new shares. At $4, the same cash amount would have required about 16.266 million shares. The actual subscription therefore used roughly 12.271 million more shares than that simple $4 counterfactual. This is an illustration, not a claim that Coincheck could have sold shares to KDDI at $4. The March price came from another transaction and does not establish an available June financing price.[2][4][1]

Monex’s voting agreement produced an 85.9% figure without transferring 85.9% ownership

The most easily misunderstood number in the KDDI filing is 85.9%. KDDI’s Schedule 13D reported shared voting power that could include 136,247,594 Coincheck shares held by Monex under a voting agreement, in addition to KDDI’s own shares. The agreement required Monex to support KDDI’s nominated director under specified conditions. It did not give KDDI shared power to dispose of Monex’s shares, and KDDI disclaimed broader beneficial ownership and pecuniary interest in them. The 85.9% is therefore a purpose-limited voting calculation, not an economic ownership stake.[4][6]

That boundary matters to any claim that KDDI “controls” Coincheck. KDDI owned 14.9% after the subscription according to the transaction announcement. It gained a nomination right and a voting arrangement supporting that nominee. Those facts establish influence and contractual cooperation. They do not, without more evidence, establish that KDDI acquired Monex’s economic interest, could sell Monex’s shares or controlled every shareholder vote. Control for accounting, corporate-law and takeover purposes can also use different tests.[5][4][6]

The chain changes how investors should read dilution and control

Together, the transactions issued more than 56.4 million Coincheck shares. The 3iQ shares brought an operating asset into the group; the KDDI shares brought cash and a strategic relationship. Adding the share counts is useful for dilution analysis, but adding their “values” as though both were cash proceeds would be wrong. The 3iQ contractual value was consideration for a business; the KDDI amount was financing. Similarly, using the $2.28 issue price to revalue the 3iQ transaction retrospectively would ignore the agreed merger terms and common-control accounting.[1][2][5]

The two deals also reconfigured relationships around Monex. In March, Monex became the recipient of most shares issued for 3iQ. In June, its existing stake supported a director-nomination arrangement for KDDI. That is a documented governance connection, not evidence of a concealed transfer or collusive pricing. A stronger adverse inference would require proof about negotiation conduct, undisclosed side payments, fiduciary process or conflicts beyond the public transaction documents. The examined records do not provide that proof.[1][4][6]

What comment could resolve

The records leave several unresolved questions. Coincheck could explain how the $4 contractual value was selected, what accounts for the difference between $111.840 million and the $111.643 million simple share calculation, and how its board evaluated the $2.28 KDDI price only three months later. It could also clarify whether the alliance rights affected the issue price and how it characterises KDDI’s influence under the voting agreement. Monex and KDDI could explain the practical limits of the nominee-support arrangement. No response should be implied where none was obtained.[1][2][4][6]

The central finding survives those unanswered questions. Coincheck used a $4 share value to transfer 3iQ within a common-control transaction, then sold new shares for cash at $2.28 to a strategic investor. The 43% difference is important for dilution and deal interpretation, but it is not a valid standalone measure of company-value destruction. The governance documents create another apparent headline—85.9% shared voting power—that also narrows when the rights are read closely. The evidence shows how transaction price, accounting value, economic ownership and purpose-limited voting power can diverge around the same issuer.[1][2][4][6][5]

The share count makes the pricing difference tangible

Across the two transactions, Coincheck issued 56,447,361 shares. At the respective contractual and cash prices, the disclosed equity consideration and new-money investment total about $176.7 million before transaction adjustments. Applying either price to the whole 56.4 million-share block would be misleading: $4 belongs to the 3iQ exchange formula and $2.28 to KDDI’s cash subscription. The aggregate share count is suitable for dilution analysis; the mixed-price dollar sum is suitable only as a description of two separate deals.[1][2][4]

Existing shareholders experienced dilution from both issuances, but they also received different assets in return: ownership of 3iQ’s business and approximately $65 million of new cash plus a strategic alliance. A dilution percentage by itself cannot establish value transfer. That would require pre- and post-transaction share counts, a defensible value for the acquired business and alliance, transaction costs, and evidence about whether the issue prices were fair relative to alternatives available on each date.[1][2][5]

The governance arrangement should be monitored after the nominee vote. If KDDI’s shared-voting disclosure falls away once the specified matter is completed, that would confirm its narrow purpose. If later agreements extend to broader votes, transfer restrictions or additional board rights, the control analysis would change. The current documents support strategic influence, not a blanket conclusion that KDDI owns or controls 85.9% of Coincheck.[4][6]
