Kochav Defense Acquisition Corp.: BERKLEY W R CORP amends Schedule 13G stake filing

W.R. Berkley Corp. filed an amended Schedule 13G with the SEC (accession 0001628280-26-072400) updating its beneficial ownership stake in Kochav Defense Acquisition Corp., a special purpose acquisition company. The filing signals a change in the insurer's passive position in the defense-focused blank-check vehicle, though the amended document did not immediately disclose revised share counts or percentage figures. Schedule 13G amendments are typically triggered when ownership crosses the 5% threshold or when a holder's stake shifts by more than 5% of the class. The update matters because it clarifies whether W.R. Berkley remains a significant backer of Kochav as the SPAC pursues a merger target in the defense sector. Investors will watch for Kochav's next deal announcement and any further 13G/13D filings that reveal the size and intent of W.R. Berkley's position.
