Monitor the final IPO pricing and first-day trading performance for BMB. The company's strong revenue growth (50% YoY in H1 2026) and high Adjusted EBITDA margins (45%) are positive, but the Up-C structure, significant debt ($548M), and substantial Tax Receivable Agreement obligations (~$368M over 19 years) create complexity. Post-IPO, watch for insider selling lock-up expirations and the pace of geographic expansion beyond California and Texas.
