The firm holds founding membership of ADVIOR International, a global mid-market M&A advisory network with reach in 42 countries.

Investment thesis

ATRIUM Partners is a fee-for-service M&A and capital markets advisor rather than a principal investor. The firm advisory thesis centres on Nordic mid-market M&A with particular concentration in Danish corporate transactions across financial services, software and technology, industrial manufacturing, consumer goods, energy transition including biogas where the firm has executed multiple mandates in recent vintages, and healthcare. Geographic scope is primarily Denmark with cross-border execution capability through the ADVIOR network across the Nordics and pan-European markets. Service mix spans sell-side and buy-side M&A, mergers and joint ventures, carve-outs, generational succession transactions for family-owned businesses, equity capital markets advisory covering IPOs, follow-ons and delistings, and debt advisory including capital structure optimisation. Approximately 75 percent of mandates are sell-side engagements. There is no ticket-size band or limited partner base as ATRIUM is compensated by transaction fees rather than by managed capital.

Recent activity

Recent advisory mandates span automotive distribution (2024), transport services (2025), logistics technology (2025), software (2025), environmental engineering services and industrial divestitures, with approximately 75 percent of engagements being sell-side. Because ATRIUM is an advisor rather than a principal investor, these transactions reflect mandates executed on behalf of clients rather than portfolio holdings or realisations. The firm continues to advise Nordic mid-market corporate and private equity clients across complex M&A processes and energy-transition transactions.
