Insights

Corporate Governance Analyst

Major holder reports 21.3% stake on a conversion basis.

The report lists 10,200,000 shares beneficially owned by the reporting person, split into 200,000 Class A and 10,000,000 Class B shares, and uses the issuer's capital as of December 31, 2025 to compute 21.3%.

Because Class B shares carry ten votes each, the filing cautions that voting power may exceed the percentage shown; governance implications depend on the holder's voting alignment with other insiders.

Capital Markets Specialist

Conversion treatment affects percentage but not an immediate issuance.

The filing explicitly treats Class B shares as converted only for calculating percentage ownership; it does not state any new issuance or transfer of shares. The reported figures are tied to the stated share counts as of December 31, 2025.

Market impact or dilution is not described here; subsequent filings would be required to disclose any transfers, offerings, or changes in issued share capital.
