Insights

Financial Analyst

TL;DR: The Berkley entities report no beneficial ownership in MSSAU; this is a routine, neutral disclosure with negligible market impact.

The amended Schedule 13G/A documents that W. R. Berkley Corporation and Berkley Insurance Company each report 0 shares (0%) of Metal Sky Star Acquisition Corporation (CUSIP G6053N105). For investors and market watchers, this confirms the Berkley entities do not hold a stake that would influence ownership or strategy.

Corporate Governance Expert
