Irwin Mitchell Advises Lhasa on Acquisition of Spektra Consultoria

Showcasing Irwin Mitchell’s Expertise in Complex International Transactions
10.12.2025
Irwin Mitchell’s Corporate team has advised Lhasa Limited, parent company of Consult Lhasa, on its acquisition of Brazil-based toxicology consultancy, Spektra Consultoria.
The transaction further strengthens Lhasa’s presence in Latin America and, in particular, will enable the group to provide greater value to Brazilian based clients.
Gavin Maddison and Henry Thompson from Irwin Mitchell acted for Lhasa Limited on the acquisition. Veirano Advogados provided legal counsel in Brazil and Forvis Mazars were engaged on financial due diligence.
Gavin Maddison, Corporate partner in Irwin Mitchell, said: “We’re proud to have supported Lhasa on this strategically important cross border acquisition. Bringing Spektra’s local regulatory expertise together with Consult Lhasa’s global scientific capabilities will deliver real benefits for clients. We wish Lhasa and Spektra every success for their partnership.”
Dr Crina Heghes, CEO at Consult Lhasa, said: “Our long-standing collaboration with Spektra has shown us the tremendous potential of joining forces. By welcoming Spektra into the Consult Lhasa team, we can offer clients the best of both organisations and deliver even greater value.
Dr Chris Barber, CEO at Lhasa Limited, said “We are grateful for the expert guidance and support provided by Irwin Mitchell throughout this process, which has been instrumental in ensuring a smooth and successful transaction.”
Earlier this year, Irwin Mitchell also supported Lhasa in completing the twinned acquisitions of Molecular Networks GmbH Computerchemie (Germany) and Altamira LLC (USA), further evidencing the firm’s experience advising on complex international transactions.
