The Governance Gap: What acquisition leaves behind

Acquisitions generate a particular kind of excitement: the commercial opportunity, the strategic fit, and of course, the expanded footprint. These are the conversations that fill boardrooms and drive teams to work through nights and weekends. Company secretaries are typically the last to be included in those conversations. At the conference, moderator Samantha Yu, (Senior Manager - UK Entity Management), alongside panellists Lauren Geary, (Senior Manager - UK Entity Management) and Jacques de Patoul, (Director - Corporate Secretarial Service Ireland) made the case for why that is a mistake organisations come to regret and walked the room through a practical four-phase framework for building governance into an acquisition from the outset, rather than letting it resurface as risk.

To ground the discussion, we polled the room live on how they actually handle good standing and entity governance during acquisitions and the results told a story:

• 50% of organisations only start thinking about good standing and corporate secretarial matters after the deal has already closed, post-completion or later
• 71% have missed a filing deadline in the last two years
• 78% manage 50+ entities, with over half managing 200+

Put together, this is a room full of organisations running large, complex entity portfolios, most of whom are treating governance as a post-completion clean-up job rather than a deal-stage priority and the majority have already felt the consequences.

Why the gap opens up

The governance and entity management dimension of an acquisition is not glamorous, but it is consequential. Missed filings, incomplete corporate records, and unclear responsibility chains translate into exposure, financial penalties, and hours spent firefighting problems that were preventable. When a deal completes, attention naturally shifts to integration such as people, systems, culture, customers and corporate records slide down the priority list.

The challenge is compounded by one of the most consistent features of post-acquisition environments: high staff turnover, supported by research. The institutional knowledge of who manages what, and how obligations have historically been met, often walks out the door with them. When that happens, corporate records become the source of truth and if those records are incomplete, the organisation is left with a gap it cannot easily close.

The four phases of an acquisition

Lauren and Jacques walked through how governance plays out in practice across each phase, comparing the UK and Ireland along the way:

• Pre-deal: governance-specific due diligence, a health check that surfaces gaps while seeding the entity management database, and a dormancy review to flag what can be simplified or struck off.
• Pre-completion: responsibility mapping, a UBO/beneficial ownership calendar, an integration framework, and early conversations with service providers so nothing stalls at closing.
• Post-completion: the execution sprint: UBO and beneficial ownership filings, officer and signatory changes, bank mandate updates, and the transfer of statutory books.
• Ongoing: a live compliance calendar, registers kept current rather than left to drift, and rationalisation as a standing discipline.

The pattern across every phase was the same: the earlier governance is built in, the less it costs later.

Our recommendation

Cosec support should start pre-completion, not after. Waiting until post-completion to think about good standing and entity governance leaves organisations exposed to exactly the kind of gaps and missed deadlines we are seeing in this data - the governance gap that acquisition leaves behind. Getting it right earlier means smoother integration, fewer surprises, and stronger governance from day one. The organisations doing this well are not the ones with the fewest entities, they are the ones who treated governance as part of the deal, not an afterthought to it.
