Key Financial Metrics
The filing text does not provide specific financial performance data such as revenue, profit, cash flow, margins, debt levels, or liquidity ratios. The document is a legal disclosure regarding corporate governance and shareholder agreements rather than a financial results report.
Material Changes Versus Prior Period
- Shareholder Composition: Two new shareholders, Cristiana Coutinho Beltrão and Maria Beltrão Saldanha Coelho, joined the Shareholders' Agreement. They received redeemable preferred shares as payment for dividends declared by Christy Participações Ltda.
- Shareholder Exit: Pedro Wongtschowski transferred his entire equity interest in Ultra to other Holding Partners (including Christy, IgelPar, and various individual family members) on December 23, 2025, and ceased to be a party to the agreement.
- Capital Structure: Ultra issued redeemable preferred shares to existing shareholders and the new joining shareholders.
Guidance, Outlook, and Material Provisions
The filing details specific amendments to Clause Nine (Migration Right) of the Shareholders' Agreement to regulate share exchanges involving the new redeemable preferred shares:
- Migration Rules: If a "Migration" (transfer of shares) occurs between Holding Partners, terms are freely negotiated. However, if Migration involves an exchange by Ultra, the company must mandatorily purchase all Preferred Shares held by the migrating partner for a fixed price of BRL 1.00 per share.
- Dividend Waiver: As a condition of Migration via Ultra, the migrating partner must irrevocably waive the right to receive unpaid dividends declared on December 26, 2025. This mechanism aims to balance dividend rights between migrating and remaining partners.
- Treasury Stock: Preferred Shares acquired by Ultra under these terms will be allocated to treasury and subsequently canceled.
Risks and Contingencies: The filing notes that the Addendum is governed by Brazilian Corporations Law. No specific financial risks or contingencies are disclosed in this text.
Investor Verification Checklist
- Verify the total number of redeemable preferred shares issued and the total capital increase amount in Ultra's subsequent financial statements.
- Confirm the updated shareholding percentages of the Igel family, Christy Participações, and the new joining shareholders (Cristiana and Maria Beltrão).
- Review the impact of the BRL 1.00 mandatory buyback provision on Ultra's future cash flows if significant Migration events occur.
- Check for any related party transaction disclosures regarding the dividend distribution to Christy Participações that funded the new share issuance.
