INTR · Inter & Co, Inc.

This Form 6-K serves solely to furnish Inter & Co, Inc.'s 2026 Owners' Day presentation (Exhibit 99.1), a non-transactional, forward-looking investor communication. It contains no audited or unaudited financial statements, no earnings results, no guidance ranges, no capital return announcements, and no disclosures of material agreements, acquisitions, executive changes, or financing events. The content outlines strategic themes—the 'Rule of 50', '3SA' framework, and progress against KPIs like Efficiency Ratio and ROE—but presents only high-level achievement percentages (e.g., '44% Achievement' as of Mar/2026) without underlying financial data or time-series metrics. While the document references numerous Non-IFRS measures (e.g., NIM Excluding Credit Card Transactor Portfolio, Cost to Serve), it explicitly states these are managerial metrics derived from internal data and directs readers to the Annual Report on Form 20-F for reconciliations—none of which appear here. As such, the filing provides qualitative strategic context but no new quantitative operational or financial information for modeling or valuation. Its materiality is medium because it signals management’s near-term priorities and framework evolution, yet offers no actionable financial inputs or event-driven catalysts.
