Part of the issuance reported the same day

ARIN's statistics show it reserved on 2025-12-01 and allocated (dated 2025-12-02) on 2025-12-03. ARIN removed its own pool record for this range as part of issuing it: the same report adds 199.245.199.0-199.245.199.255. The issuance is explained on that line.

No transfer record matches. ARIN's statistics show it allocated (dated 2018-09-25) on 2025-12-01 and allocated (dated 2025-12-02) on 2025-12-03. The registration was replaced with one for a different holder record, and public sources don't say why (a transfer not yet logged, a return and reissue, or an organization record change).
