## From the administrators' statement

The Company was incorporated on 29 September 2016 under the name Airspan Spectrum Holdings Limited, before changing its name to Dense Air Limited on 25 July 2018. The Company is headquartered in Marlow, England, was part of the Dense Air Group, and initially focused on acquiring radio frequency assets across the world, with initial success in lreland, Portugal, Belgium, New Zealand and Australia.

In 2022 Sidewalk Infrastructure Partners (“SIP”), a New York-based specialist technology infrastructure investor, acquired the Dense Air Group, shifting the focus to the US market and introducing a strategy to divest assets from other international markets, excluding the UK. The business model pivoted to establish long term revenue from telecommunications infrastructure developed in the UK, targeting enterprise customers (rather than Mobile Network Operators (“MNOs’)) in segments such as hospitality, commercial real estate & pharmaceuticals.

The Company, as the main entity of the IONX business, operated as a research and development (“R&D”) centre, designing business-to-business telecommunications infrastructure for Dense Air in the US, with the group’s revenue being generated primarily in the US.
