When investors assess a potential acquisition, considerable attention is typically given to financial performance, legal exposures, tax, operations, customers and commercial prospects.
But there is another area of risk that can materially affect the success of an investment and is often examined too late: remuneration and reward.
After a deal is concluded, investors may discover remuneration structures, commitments and practices that are expensive to correct, difficult to unwind or poorly aligned with the investment strategy.
What initially appears to be an HR issue can quickly become an investment, financial and execution risk.
What are you actually acquiring?
Every acquisition comes with a reward architecture, whether deliberately designed or developed over time.
An investor may inherit inconsistent job grading, outdated salary structures, pay anomalies, contractual bonuses, retention arrangements, executive remuneration commitments, legacy benefits and incentive schemes that no longer support the future strategy.
Critical employees may also be significantly below market, creating retention risk precisely when continuity is most important. Conversely, parts of the workforce may be materially above market, increasing costs and limiting flexibility during integration or restructuring.
These issues can remain hidden because remuneration is often viewed primarily as a payroll cost rather than as an interconnected system of cost, talent, performance, governance and risk.
Reward risk can affect the investment thesis
The question should not simply be: “What does this organisation currently pay its people?”
Investors should also ask: “What reward risks are we acquiring, what could they cost us, and could they affect our ability to deliver the investment thesis?”
If growth depends on digital capability, expansion or new markets, the organisation needs to attract and retain the skills required to execute that strategy.
Similarly, where value creation depends heavily on the existing management team, investors need to understand whether those executives are competitively remunerated, appropriately incentivised and likely to remain through the transition.
Reward therefore needs to be considered not only in terms of the organisation being acquired, but also the organisation the investor intends to build.
What should reward due diligence examine?
A focused assessment should identify remuneration issues that could materially influence transaction value, post-deal cost, talent retention or execution risk.
Key areas include:
- Executive remuneration and retention – competitiveness, contractual commitments, retention arrangements and incentive alignment.
- Critical and scarce skills – dependency on key individuals and capabilities that may be difficult or expensive to replace.
- Market competitiveness and internal equity – material under- or overpayment and unexplained pay differences.
- Job architecture and grading – inconsistent levels, grading anomalies and inflated titles that could complicate integration.
- Salary structures and pay ranges – market competitiveness, internal consistency and financial sustainability.
- Variable remuneration – whether STI, LTI and other incentive arrangements support the future strategy.
- Legacy commitments – contractual bonuses, guarantees, allowances, retention payments, benefits and severance provisions.
The objective is not simply to identify remuneration practices, but to understand their financial and strategic consequences.
The hidden cost of post-acquisition integration
One of the most valuable outputs of reward due diligence is understanding what will need to change after the transaction — and what that change could cost.
Harmonising remuneration is rarely as simple as moving employees onto a new salary scale.
Some employees may fall below the new ranges while others sit significantly above them. Similar roles may have different titles, grades and pay levels. Legacy benefits may need to be protected and incentive arrangements may differ substantially between businesses.
Understanding the gap between the current reward architecture and the desired future state allows investors to estimate costs and incorporate reward interventions into the integration plan.
Identifying these issues before a transaction creates choices. Discovering them afterwards creates obligations.
From due diligence to value creation
Reward due diligence should not simply identify problems. It should show how remuneration can support the value-creation plan from Day One.
For a growth investment, this may mean building a scalable job and pay architecture. For a business dependent on specialist capability, it may mean retaining critical executives and technical talent. In a turnaround, the priority may be affordability, performance differentiation and stronger alignment between incentives and business outcomes.
The appropriate response will differ from transaction to transaction. What matters is that reward is considered deliberately before the deal rather than addressed reactively afterwards.
Look before you buy
Reward problems identified after an acquisition can be expensive and disruptive to correct.
A remuneration issue can quickly become a business problem if it results in the departure of critical talent, creates unexpected integration costs or undermines the behaviours required to execute the investment strategy.
Reward due diligence gives investors the opportunity to identify these risks before they inherit them — and understand how remuneration can support value creation from Day One.
The question is therefore no longer whether remuneration belongs in transaction due diligence.
It is whether investors can afford to discover the reward risks only after the deal is done.
