WIZE Announces Additional Acquisition of Solana (SOL), Cumulative Investment Reaches ¥800 Million with Holdings Exceeding 50,000 SOL

WIZE Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; CEO: Koki Yabu; TSE Code: 3664; hereinafter "the Company") announces the acquisition of an additional ¥100 million worth of the cryptocurrency Solana (SOL), bringing its cumulative acquisition amount to approximately ¥800 million and total holdings to over 50,000 SOL. This latest purchase has lowered the average acquisition price to the ¥15,000 range. Additionally, the Company’s SOL holdings have risen to approximately 12th place globally on CoinGecko’s 'Solana Treasury Holdings' ranking (※1).

Acquisition Status

Since October 24, 2025, the Company has been continuously acquiring Solana (SOL). Given that the current SOL price has fallen below the Company’s previous average acquisition price of ¥16,750—a level the Company considers undervalued—it acquired a total of ¥100 million worth of SOL on June 12 and June 15, 2026, in two separate transactions of ¥50 million each. As a result, the cumulative acquisition amount has reached approximately ¥800 million, and total holdings, including staking rewards, have surpassed 50,000 SOL, reaching approximately 50,800 SOL.

The average acquisition price for these two recent purchases was ¥11,088 per SOL, below the Company’s previous average of ¥16,750, successfully realizing purchases at a discounted valuation.

Acquisition Details

| Date | Amount Acquired (SOL) | Acquisition Price (JPY) | Acquisition Value (JPY) | |---|---|---|---| | June 15, 2026 | 4,376.11 | 11,426 | 50,000,872 | | June 12, 2026 | 4,642.80 | 10,770 | 50,000,883 |

As the Company’s SOL holdings increase, so too does the amount of SOL indirectly held by shareholders through their stock ownership. The metric 'SOL held per 10,000 shares' has increased from approximately 1.99 SOL in February 2026 to approximately 5.46 SOL—an increase of about 2.7 times in just four months. Furthermore, the Company’s total SOL holdings are now the largest among Japanese listed companies (※1), and its position on CoinGecko’s 'Solana Treasury Holdings' ranking has risen to approximately 12th globally (※1).

Valuation and Income Returns at Different SOL Prices

The Company has further lowered its average acquisition price by purchasing additional SOL at current prices below its average cost, recognizing this as a favorable opportunity. Holdings of SOL offer two types of returns: capital gains from price appreciation and staking rewards (income gains) that accumulate annually simply by holding.

Since rewards are paid in SOL, both returns grow larger if the SOL price increases in the future. The Company believes that accumulating at low prices during this undervalued period lays the foundation for future growth.

The table below estimates the valuation and annual income returns based on the current total holdings of approximately 50,800 SOL under various SOL price scenarios. For example, if the SOL price reaches ¥40,000, the valuation would rise from approximately ¥580 million to ¥2.03 billion, and annual income returns would similarly expand by about 3.5 times.

| SOL Price | Holding Valuation | Annual Income Return | |---|---|---| | ¥11,400 (Current Price) | ~¥580 million | ~¥35–41 million | | ¥20,000 (January 2026 Level) | ~¥1.02 billion | ~¥61–71 million | | ¥30,000 (October 2025 Level) | ~¥1.52 billion | ~¥91–107 million | | ¥40,000 (January 2025 Level) | ~¥2.03 billion | ~¥122–142 million |

※ The above estimates use the SOL price of approximately ¥11,400 as of 11:00 a.m. on June 15, 2026 (※2), and assume the Company’s holdings of approximately 50,800 SOL and an annual income return equivalent to 6–7%. These projections are based on certain assumptions and do not guarantee future SOL prices, Company performance, or stock price.
