BDO in Ireland

Practice Area: Financial Services Audit & Advisory

Practice Area's Profile: As trusted advisors in business assurance, we partner with our clients to navigate the evolving complexities of the Financial Services sector. Our audit professionals deliver rigorous, independent assessments to help ensure compliance with applicable regulations, while also addressing the expectations of regulators, investors, and key stakeholders. Our proactive approach supports our clients in strengthening governance, enhancing transparency, and building confidence in their financial reporting. We were the first Irish accountancy firm to achieve registration with the Public Company Accounting Oversight Board (PCAOB), and we are proud to have set the standard in this area. This accreditation is now a prerequisite for any firm providing, or seeking to provide, audit services to US-listed companies and their Irish-based subsidiaries, a reflection of our long-standing commitment to quality, professionalism and our clients.

At the same time, audit quality and independence remain paramount. BDO is committed to maintaining the highest standards of audit quality and compliance. Independent oversight and review play an important role in strengthening confidence in the profession and supporting continuous improvement across the sector. We welcome the recent findings of IAASA's latest quality assurance review and are pleased that they recognise the strong standards applied across our audit practice. We remain focused on continually enhancing our processes and delivering high-quality audits for our clients.

Our merger with BDO UK, subject to regulatory approval, is a strategic response to these dynamics. We have worked closely with BDO UK for decades on cross-border engagements, and the cultural alignment between our firms has been a critical factor. This combination will further strengthen our integrated audit capability across Ireland and the UK, expanding our Financial Services expertise and enhancing the support we provide to clients operating across increasingly international markets.
