ISIN US12811P1084; LEI 549300S5PS2P178Z6N82. Security type is non-operating entity type (other). Segment, sector and jurisdiction are not on the record. Listing status: listed, not halted.\n\n## The disclosure read\n\nThe record holds 19 filings across 16 filing days in the window 2025-11-08 to 2026-11-08: 15 regulatory filings, 2 directors' dealings, 1 AGM/EGM and 1 prospectus.

The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting, name change or segment move lines. Domicile change is not on the record, because EDGAR states no dated change of state of incorporation on a filing line.
