2. July 2025

Munich — INTARIA AG, a leading provi­der of audit and tax advi­sory services for medium-sized clients in Germany, has ente­red into a stra­te­gic part­ner­ship with Moore Belgium, Moore DRV from the Nether­lands and Moore King­s­ton Smith from the UK. In this context, Moore Belgium has acqui­red a majo­rity stake in INTARIA, wher­eby the INTARIA part­ner­ship will conti­nue to manage the German busi­ness as entrepreneurs. 

In the coming years, the service port­fo­lio is to be expan­ded through targe­ted acqui­si­ti­ons and mergers and the geogra­phi­cal coverage within Germany is to be streng­the­ned. INTA­RIA’s clear objec­tive in taking this step is to build a group that will provide custo­mers from the SME sector with a full range of services as a trus­ted part­ner. The merger will also enable them to bene­fit from inte­gra­ted support across borders for their Euro­pean issues. 

Moore Belgium, Moore DRV, Moore King­s­ton Smith and INTARIA have alre­ady been coope­ra­ting for some time in the Moore Global network and now want to signi­fi­cantly inten­sify this coope­ra­tion as a Euro­pean group of natio­nal cham­pi­ons in order to offer clients from the Euro­pean upper midmar­ket a seam­less inter­na­tio­nal offe­ring and to tackle the dyna­mic chal­lenges in the audi­ting and tax consul­ting indus­try with combi­ned forces. In addi­tion, a declared goal of Moore Belgi­um’s invest­ment in INTARIA is to acce­le­rate INTA­RIA’s growth as one of the German market leaders in the SME sector. Among other things, the Belgian company’s expe­ri­ence in inor­ga­nic and orga­nic growth will serve as a driving force. As part of the tran­sac­tion, the opera­tio­nal manage­ment and respon­si­bi­lity for the busi­ness in Germany will remain in the hands of the INTARIA part­ners, who will also retain a signi­fi­cant share­hol­ding. INTARIA has appoin­ted addi­tio­nal part­ners who, toge­ther with the exis­ting team, will drive forward the imple­men­ta­tion of the ambi­tious growth strategy. 

Focus on acqui­si­ti­ons and orga­nic growth levers

In view of the dyna­mi­cally deve­lo­ping market envi­ron­ment, the future closer part­ner­ship with Moore Belgium, Moore DRV and Moore King­s­ton Smith offers INTARIA the oppor­tu­nity to diffe­ren­tiate itself stra­te­gi­cally and opera­tio­nally from the local compe­ti­tion as part of a Euro­pean group of leading provi­ders for SMEs and to find answers to the rapidly chan­ging client requi­re­ments. Moore Belgium, Moore DRV and Moore King­s­ton Smith are the three largest Moore Global network members in Europe and are on a dyna­mic growth path, which has been supported for seve­ral years by the Euro­pean invest­ment company Water­land with capi­tal and compre­hen­sive know-how. INTARIA expects a wide range of addi­tio­nal growth poten­tial within this network for the bene­fit of custo­mers and employees. For exam­ple, INTARIA will be able to offer its more than 1,100 clients addi­tio­nal services, such as advice on digi­tal analy­tics or subsi­dies, as a result of the closer coope­ra­tion and thus further streng­then its posi­tion as a flexi­ble solu­tion part­ner. At the same time, as part of the growth stra­tegy, indus­try exper­tise is to be built up and expan­ded in order to be able to support clients with addi­tio­nal exper­tise in future challenges. 

In addi­tion, INTARIA will gain access to the latest tech­no­lo­gi­cal tools and AI-based solu­ti­ons that Moore Belgium, Moore DRV and Moore King­s­ton Smith, and in the future INTARIA, are jointly deve­lo­ping to be at the fore­front of digi­tal deve­lo­p­ments in the profes­sion. In this way, INTARIA will be able to bene­fit from the use of inno­va­tive tech­no­lo­gies for grea­ter process digi­tiza­tion and streng­then its compe­ti­ti­ve­ness. At the same time, the focus will remain on the quality and inde­pen­dence of its advi­sory services and its close proxi­mity to clients in day-to-day business. 

“INTARIA has deve­lo­ped stron­gly in recent years and has grown steadily. Our clients appre­ciate the quality and our DNA ‘From SMEs for SMEs’. By part­ne­ring with Moore Belgium, Moore DRV and Moore King­s­ton Smith, with whom we share values and goals, we will advise the Euro­pean upper mid-market even more compre­hen­si­vely and across natio­nal borders, while paving the way to signi­fi­cantly acce­le­rate INTA­RIA’s natio­nal growth,” explains Thomas Zieg­ler, Mana­ging Part­ner of INTARIA (photo © INTARIA).

Fabian Galler, also Mana­ging Part­ner, adds: “Our almost 200 employees are the foun­da­tion of our successful deve­lo­p­ment. By conti­nuously expan­ding the team over the years, we have been able to create a culture charac­te­ri­zed by cohe­sion, quality aware­ness and expert know-how. Based on these values, we want to acce­le­rate our growth course and are convin­ced that the constel­la­tion as a new strong player will give us all addi­tio­nal clout in the market.”

Peter Verschel­den, Execu­tive Chair­man of Moore Belgium, comm­ents: “I am deligh­ted with this new part­ner­ship with INTARIA. As a company we share the same values, appre­cia­tion for our employees and the same vision for how we want to advise our custo­mers. This part­ner­ship enables us both to serve our clients with the same high quality stan­dards across natio­nal borders. Germany is an important econo­mic market for many clients within our Group and vice versa. I look forward to conti­nuing to grow together.”
