Cheonbo

CEO and 10%+ shareholder Lee Sang-ryul reported acquiring 39,720 common shares of Cheonbo via on-market purchases on June 19, 2026, lifting his direct stake from 3,300,000 to 3,339,720 shares. Purchase prices ranged approximately KRW 42,500-43,700 per share, suggesting roughly KRW 1.7 billion deployed. Including convertible/warrant-linked instruments (958,244 units), his total beneficial holding rose to 4,297,964 securities. However, his ownership ratio fell to 27.26% (common stock) and 29.34% (including derivatives) from 33.00%/34.35% previously, reflecting share count dilution since the prior November 2024 report. Insider buying by the founder-CEO at current price levels is typically read as a confidence signal.

The largest shareholder, Lee Sang-ryul, and related parties increased their combined holdings from 7,938,704 shares (54.20%) to 7,998,894 shares (54.61%), an increase of 60,190 shares (+0.41pp). Voting-right shares rose from 5,543,093 (45.24%) to 5,603,283 (45.73%). The stated purpose is to influence management control, with stock price stabilization and enhancing shareholder value cited as the rationale. The reporting party explicitly affirms substantive influence over board appointments, capital actions, dividends, and M&A. The 14-member special-related-party group includes family members, executives, and affiliates Cheonbo Precision and Solique Investment.

Largest shareholder and CEO Lee Sang-ryul filed an updated major shareholding report as of June 12, 2026. While he and related parties acquired 491 additional shares, the total holding ratio fell sharply from 64.04% to 54.20% (-9.84pp) because the total issued shares ballooned from 10,000,000 to 12,253,025 following convertible bond (CB) conversion into common stock. Voting-right ratio also dropped from 55.42% to 45.24% (-10.18pp), meaning the controlling group now holds less than half of voting rights. The number of special-related parties increased from 12 to 14. The filing reaffirms management-control purpose, but the dilution from CB conversion is a meaningful overhang for minority shareholders.

A newly appointed managing director, Lee Keun-pil, filed his initial report on ownership of specific securities after purchasing 301 common shares on the open market on June 11, 2026 at KRW 38,507 per share. The total holding represents just 0.00% of the 12,253,025 outstanding shares, amounting to roughly KRW 11.6 million in value. The filing is a routine disclosure triggered by his appointment as a registered managing director on March 24, 2026. While the absolute transaction size is small, insider purchases by newly appointed executives are often viewed as a mild signal of confidence in the company.

Holders of the 6th private placement convertible bonds exercised conversion rights on three dates (April 30, May 18, and June 1), converting approximately KRW 3.46 billion in principal into 79,465 new shares at a conversion price of KRW 43,541. The new shares represent 0.65% of the current 12,180,680 shares outstanding and will be listed on May 15 and June 12. After this exercise, KRW 101.9 billion of the original KRW 200 billion 6th-series CB remains unconverted, with potential dilution of up to 2,340,322 additional shares. Continued conversions create ongoing overhang and dilution risk for existing shareholders.

Subsidiary Cheonbo BLS completed the issuance of its 1st unregistered, coupon-bearing, unsecured private placement convertible bonds, with the full KRW 78.2 billion paid in on May 29, 2026. The board originally resolved on the issuance on May 22, 2026, and the actual issued amount matched the planned amount in full. The CBs will not be listed. This is a sizable capital raise at the subsidiary level that strengthens funding but introduces potential future dilution at the subsidiary upon conversion.

Cheonbo's subsidiary Cheonbo BLS has resolved to issue KRW 78.2 billion of unregistered, unguaranteed private convertible bonds (1.0% coupon / 4.0% yield-to-maturity, maturing 2033-05-29) to Mirae Asset Renaissance New Energy PEF. Proceeds will fund facility investment (KRW 54.74B) and working capital (KRW 23.46B). The conversion price is set at KRW 39,463 per share, potentially issuing up to 1,981,603 new shares (26.07% of total). Refixing terms include a performance-linked adjustment if FY2029 EBITDA falls below KRW 80 billion (floor at 50% of initial conversion price), plus standard dilution protections. A 30% call option (up to KRW 23.46B) and put option exercisable from year 5 are attached, with a qualified IPO covenant.

Cheonbo filed its Q1 2026 quarterly report covering January 1 to March 31, 2026, the company's 20th fiscal year. The report confirms three unlisted consolidated subsidiaries with no changes during the period, and reaffirms the company's classification as a mid-sized enterprise. A credit rating of BB+ was assigned by Korea Enterprise Data on April 1, 2026, indicating debt repayment capability remains adequate but with speculative elements under changing market conditions. The disclosure also recaps the corporate history, including the 2017 spin-off of Cheonbo Shinsozai, the 2019 KOSDAQ listing, and recent capital injections into subsidiaries Cheonbo Shinsozai and Cheonbo BLS. No major business restructuring, M&A, or management changes are reported in this filing excerpt.
