Super League shareholders have approved a transaction that would hand Japanese Bitcoin treasury firm Metaplanet control of the Nasdaq-listed company, setting up a path for a US-focused expansion built around acquiring more Bitcoin. The vote, detailed in a Monday announcement and accompanying SEC filing, also includes major governance and financing changes designed to make Bitcoin accumulation a central part of the rebranded business.

Under the approved terms, Metaplanet is set to buy into Super League in a deal structured around common shares, governance-linked preferred stock, and warrants. The company plans to rename itself Superplanet and pursue a capital markets strategy aimed at increasing Bitcoin holdings on a per-share basis.

Key takeaways

Shareholders approved a plan that would give Metaplanet a 93.7% ownership stake in Super League, subject to transaction closing.
Metaplanet will contribute 2,100 BTC and $2.5 million for 44.86 million Super League common shares, governance-preferred stock, and 10-year warrants.
Super League intends to rebrand as Superplanet and adopt the Nasdaq ticker SUPA, with a stated focus on Bitcoin per-share growth.
The financing plan emphasizes preferred securities—including senior, non-convertible perpetual preferred shares—to fund future Bitcoin purchases without relying primarily on conventional debt.
Metaplanet says it has accumulated 44,000 BTC, according to industry treasury tracking data cited in the company materials.

Shareholder approval clears the way for Metaplanet control

According to a Monday announcement on Super League’s investor relations website and a related filing with the US Securities and Exchange Commission, shareholders approved all proposals connected to the planned issuance of up to 435.9 million common shares. The issuance is tied to agreements involving Metaplanet and Evo Fund.

As described in the SEC documentation, Metaplanet will contribute 2,100 Bitcoin (BTC) and $2.5 million in cash in exchange for:

44.86 million common shares;
100 shares of convertible perpetual preferred stock carrying governance rights; and
10-year warrants for additional common stock.

The transaction is designed to transfer practical control to Metaplanet. The company would be able to designate a majority of the board and approve major corporate decisions, giving it significant influence over Super League’s future direction. Super League also states that Metaplanet’s common shares would be subject to a five-year lock-up.

In conjunction with the ownership shift, Super League plans to rebrand as Superplanet and move to the Nasdaq ticker SUPA. Management’s strategy, as outlined in the materials, centers on increasing Bitcoin holdings per share.

Preferred-stock financing becomes the backbone of the Bitcoin plan

A notable feature of the approved restructuring is the intended approach to raising new capital for additional Bitcoin acquisitions. Rather than depending primarily on debt, Superplanet plans to finance purchases through senior, non-convertible perpetual preferred shares.

The filing also describes an additional source of potential support: Metaplanet would have the option to invest up to $210 million in junior preferred stock. Together, these instruments are intended to create a more flexible funding stack for Bitcoin treasury activity while avoiding reliance on traditional borrowing as the dominant mechanism.

This matters for investors because capital structure decisions can affect dilution, governance outcomes, and risk during downturns. Preferred securities can also change how future investors evaluate the company’s balance-sheet leverage and incentives, especially for businesses where asset accumulation—here, Bitcoin—is the primary operating goal.

Why the US route is seen as strategically important

Super League’s US-facing expansion is framed as a response to what it describes as sufficient market demand for preferred securities issued by Bitcoin treasury companies. In an Oct. 15 SEC filing, Super League said the US market for preferred securities is now large enough to support new entrants, and that the proposed financing structure would provide another funding source for Bitcoin purchases without relying primarily on conventional debt.

The approved plan also explicitly builds on Metaplanet’s existing ability to raise capital in Japan using yen-denominated financing. By adding a US dollar funding channel through preferred offerings, management is effectively diversifying where capital comes from while aligning the financing currency with the broader expectations of US capital markets.

For readers tracking the broader “Bitcoin treasury” sector, this is part of a wider pattern: corporate treasury operators increasingly seek capital markets vehicles that can sustain periodic Bitcoin accumulation. The Superplanet/METAPLANET structure underscores how governance rights and long-dated warrants can be combined with preferred financing to keep liquidity flowing toward crypto exposure.

Metaplanet’s growing BTC position and the next questions

The deal arrives as Metaplanet continues to expand its Bitcoin holdings. The company cites industry treasury data indicating it has accumulated 44,000 BTC, placing it as the second-largest publicly traded corporate Bitcoin holder behind Strategy, according to the tracker referenced in the article.

In addition, Superplanet’s post-transaction plan appears tied to a broader evolution in Metaplanet’s strategy. Earlier in the month, Metaplanet proposed allocating up to 15% of its total assets toward strategic investments intended to help finance Bitcoin purchases and dividend payments. That shift suggests the company is not treating Bitcoin accumulation as the only output of its balance sheet, but also exploring ways to generate liquidity and shareholder returns alongside treasury growth.

What remains to watch is the closing process and how Superplanet’s preferred-security roadmap translates into actual Bitcoin purchases over time. Investors should also look for details on board composition, the timing and terms of any future preferred issuances, and the extent to which dilution from warrants and share issuances will affect the company’s “Bitcoin per share” objective.
