While reacting to his recognition by The Guardian as one of Nigeria’s “Sixty Most Inspiring, Visionary and Transformative Business Leaders That Shaped Nigeria’s Economic Growth In 2026”, Dr. Abel Onyeke spoke on what inspired Nexia Nigeria’s excellence, its corporate vision and success story, as well as Nexia Nigeria’s firm’s engagements and partnerships, and the long-term vision for company, amongst sundry issues. Excerpts …

As an indigenous multi-skill and multi-discipline professional advisory firm, what can you say inspired Nexia Nigeria to go into its key business area and how can you describe the company’s impact in the sector where it operates and by extension the company’s contribution to Nigeria’s GDP growth in the last twelve months?

Nexia Nigeria was established in November 2004 by professionals who had learnt their craft at KPMG and Deloitte. The founding conviction was simple: first-class professional service should not be the exclusive preserve of multinationals. Nigerian SMEs, family businesses and public institutions deserve the same rigour, delivered at a sensible cost and with direct access to senior people.

That conviction still shapes the firm. From Lagos, Abuja and Kaduna, our five partners and professional teams serve listed and private companies, public institutions and donor-funded programmes. Our work spans audit, tax, restructuring, forensic investigations and advisory.

Our contribution to GDP lies in strengthening the conditions for growth. Reliable financial statements improve access to credit and investor confidence. Sound tax advice supports compliance and public revenue. Restructuring protects viable jobs, while forensic and donor-funded work strengthens accountability. Over the last twelve months, our role has been to help clients make credible decisions in a difficult economy. We do not claim to move GDP single-handedly. We help keep the machinery honest, and that matters.

What are the key projects, engagements and partnerships that have shaped the company’s growth, especially those that were delivered in recent time and others that are currently under development?

Our recent growth has three markers. First, sustained assurance work across construction, energy, manufacturing, financial services, government and development programmes. Nairametrics’ reviews have continued to place us among the indigenous firms competing outside the Big Four. Its July 2026 mapping also underlines the context: the Big Four accounted for 59.38% of the 128 companies reviewed. For an indigenous firm, every credible mandate outside that concentration is earned, not inherited.

Second, partnerships. Nexia International gives us access to global methods, training and cross-border capacity. A Nexia International case study published in 2025 records our role in a partner-led, multi-country audit for a US$3.5 billion trading and distribution group. That is Bridging Global Gaps with the work attached.

Third, future capability. We are investing in ESG and sustainability assurance, integrated reporting, data-enabled audit, cyber-risk advisory, transfer pricing and global mobility. These are not decorative service lines. They reflect what Nigerian clients now ask us to solve.

How can you describe the nexus between the corporate vision of Nexia Nigeria and its success story, cutting-edge advantage, growth trajectory and how the company has been able to earn the trust of both clients/customers and shareholders?

Our vision is Care + Growth. We want our people, clients and communities to develop together. The phrase is short; the work is not.

The connection between vision and success is consistency. We apply global methods with local judgement, keep partners close to engagements, train continuously and review quality before work reaches the client. That approach has carried the firm from a 2004 start-up to a multi-city practice serving clients across the private, public and development sectors.

Our visibility has also increased over the last five years. The Guardian recognised Dr Abel Onyeke among Nigeria’s 60 result-driven and award-winning professionals driving national economic growth. Nairametrics profiled our Managing Partner, Alexander Kofi Peddler, among 10 leaders steering Nigeria’s leading audit firms. Nexia International, our global network, rose to eighth place in the International Accounting Bulletin World Survey ranking in 2021 and retained that position in 2022. Equally important, the FRC concluded its 2025 review with all identified issues satisfactorily resolved. We treat that as affirmation, not a trophy. Quality should survive daylight.

Can you attribute the aforementioned success story to what makes Nexia Nigeria different from other Nigerian companies, especially in its approach to quality assurance, global best practice in its operations, as well as the high standard in products and services?

Yes, but a difference matters only when the client can feel it. Three choices define our approach.

We are partner-led. Senior people remain involved from planning to sign-off, so clients do not pay for judgement and receive a revolving cast.

We are globally benchmarked and locally grounded. Our Nexia International membership shapes our methodology, training and quality management. Our Nigerian experience shapes how we apply them. A global manual is useful; local judgement makes it usable.

We deliberately serve the middle of the market. SMEs, family businesses, public institutions and non-profits need the same professional standards as multinational corporations, delivered with flexibility and at a sensible cost. That is Democratizing Excellence in practice.

Quality assurance is embedded in client acceptance, planning, fieldwork, consultation and review. We are accountable to ICAN, CITN, the FRC and the Nexia network. The first test is simpler: would we be comfortable defending our work in public?

In your own opinion, what are the major challenges facing entrepreneurs like you in Nigeria today and how have you been able to consistently navigate through them?

Entrepreneurs face foreign-exchange swings, inflation, expensive credit, power costs, regulatory overlap and a shortage of specialist talent. None of these challenges is new, but their combination is demanding.

We navigate them through prudence, diversification and relevance. Our client base cuts across sectors, our costs are managed carefully, and our tax, restructuring, forensic and governance services address the problems difficult seasons create. We also continue to invest in people because software can process data, but it cannot replace professional skepticism or the courage to give unwelcome advice.

Most importantly, we apply the same governance standards internally that we recommend to clients. It is difficult to preach controls with a straight face when your own house ignores them.

Can you tell us more about the long-term vision for Nexia Nigeria?

By 2035, we want Nexia Nigeria to be larger, deeper and more influential, without losing the personal service that brought us this far.

Scale means more than 200 professionals, a wider Nigerian footprint and selective expansion into West Africa. Capability means leadership in ESG assurance, integrated reporting, data-enabled audit, transaction advisory and cross-border tax. Talent means developing Nigerian professionals who can serve confidently anywhere in the world, including those who will become the firm’s next partners. Legacy means proving that an indigenous firm can combine international quality with local accessibility.

The last five years have made us more visible. The next ten should make us more useful. Bigger, yes, but never too big to know our clients.
