Pulsar Group and ResponseSource face HMRC winding-up petition
UK AIM-listed Pulsar Group and its media-matching subsidiary ResponseSource face HMRC winding-up petitions, with a separate petition filed against ResponseSource over unpaid taxes. The group says it is in regular dialogue with HMRC about the timing of VAT and PAYE payments, noting substantial amounts already paid and expecting the rest from normal cash collections. The company reported £33m record revenue for the six months to May 31, 2026.
