English to Spanish Bus/Financial Economics corporate information brochure

Brochure from UK group of companies dealing with advisory and tax services to other companies around the world.

"Working together with our associates, we were involved in the initial admission
of the parent company to AIM and the subsequent reverse acquisition of certain utility assets in
Argentina and the readmission to trading on AIM of the parent company."

I am assuming they are assets deriving from utility companies or the utility market but I would like to be sure.

"activos de servicios públicos" does not ring any bells...

Any help appreciated
TIA
