“The Energy Transition and Pillar Two Are Breaking the Old Rules”: Haitham Abdelkader on Tax-Auditing Conflicts in 2026

Haitham Abdelkader is one of the most experienced and respected leaders in tax and statutory compliance in the global energy sector.

He is currently the Head of Europe & META Tax Organization at GE Vernova. Haitham oversees statutory reporting, tax compliance, and audit defense, and is also responsible for working with approximately 60 countries spanning Europe, the Middle East, Turkey, and Africa.

Managing financial exposure estimated at $5 billion to $7 billion, Abdelkader ensures seamless alignment among U.S. GAAP, IFRS, local accounting frameworks, and ever-evolving tax regulations.

With more than 20 years of progressive experience, his career began at KPMG Egypt as a Senior Auditor, advanced to Audit Manager at KPMG Saudi Arabia, and continued at GE (now GE Vernova) since 2009.

He led the build-out of a high-performing shared service center in Cairo, transforming fragmented compliance operations into a standardized, audit-ready model serving the entire EMEA region. A Certified Chartered Accountant in Egypt since 2002 and holder of the IFRS Certificate from ACCA, Abdelkader is currently completing his MBA at the University of South Florida.

Hiatham is known for his hands-on technical mastery and proactive risk management. He has repeatedly turned complex regulatory conflicts into defensible, value-preserving outcomes for one of the world’s largest energy companies.

In this interview, Haitham discusses how the OECD’s Pillar Two Global Minimum Tax and the accelerating energy transition are fundamentally rewriting the rules of multinational tax compliance in 2026.

Silicon Review: With OECD's Pillar Two (Global Minimum Tax) now in effect and energy companies restructuring for net-zero goals, how have your priorities changed compared to five years ago?

Haitham: Five years ago, our primary focus was local statutory compliance. Then we had to ensure timely filings, clear backlogs, and alignment of financial statements with local GAAP and tax laws in each jurisdiction.

Today, Pillar Two has introduced a completely new layer of complexity. We now need to model the global effective tax rate (ETR) at the consolidated level while satisfying local rules. Energy companies are shifting from traditional fossil fuels to renewables, hydrogen, and carbon-capture projects, which create new tax attributes—credits, incentives, and timing differences—that interact with Pillar Two’s 15% minimum tax and top-up tax mechanisms.

My priorities have shifted dramatically toward forward-looking scenario modeling. Instead of simply reconciling U.S. GAAP or IFRS with local tax law after the fact, we now run sophisticated simulations.

For example, if natural gas prices in Europe spike and we accelerate our wind-farm investments in Africa, how would that affect the ETR calculation across three countries simultaneously?

Now we have to manage local exposures, jurisdictional blending, qualified refundable tax credits, and safe-harbor elections under Pillar Two.

This requires deeper integration between tax, finance, and business strategy teams than ever before.

Silicon Review: You’ve mentioned that the game has changed completely with Pillar Two and the energy transition. In 2026, what does that look like on the ground?

Haitham: In 2026, the game has changed completely. Previously, we could treat each country in relative isolation. Pillar Two forces a global minimum tax lens across the entire group. A restructuring project in one jurisdiction—say, a net-zero transition that qualifies for generous local green incentives—can now trigger top-up tax liabilities elsewhere if the overall ETR falls below 15%. Energy price volatility adds another variable: fluctuating commodity prices directly impact taxable income, deferred tax assets, and even the application of the GloBE rules.

In 2026, you can't just align local tax positions anymore—you have to model how a change in natural gas prices in Europe affects your effective tax rate under OECD rules in three different countries simultaneously.

At GE Vernova, we manage operations across roughly 60 countries with vastly different tax regimes, languages, and audit cultures. My team in Cairo and Budapest must now maintain standardized data rooms that feed both local statutory filings and the new Pillar Two calculations. We’ve had to upgrade our processes to capture granular country-by-country reporting (CbCR) data in real time. The old “file and forget” approach to local compliance is obsolete. Every decision now requires stress-testing against both local enforcement and the global minimum tax framework.

Silicon Review: How are the stakes even higher now with Pillar Two?

Haitham: The stakes are significantly higher for two reasons. First, Pillar Two introduces automatic top-up tax mechanisms that cannot be negotiated away locally. If your ETR is below 15% in a jurisdiction, the parent company or another group entity may be required to pay the difference—potentially creating unexpected cash outflows and earnings volatility.

Second, the energy transition itself carries heightened regulatory and reputational risk. Governments are simultaneously offering green incentives while cracking down on base erosion. Directors remain personally liable in many jurisdictions for inaccuracies in filings, and non-compliance can now trigger both local penalties and global tax adjustments.

In practice, a single misalignment among IFRS reporting, local tax law, and Pillar Two calculations can result in multimillion-dollar exposures. That’s why I remain deeply hands-on. I still roll up my sleeves and dive into the details when a complex transaction or audit surfaces.

Silicon Review: Can you share a concrete example of how you apply this technical mastery in practice?

Haitham: Certainly. A few years ago, we identified a material transfer-pricing issue at a major UK entity. The internal margins on related-party transactions deviated from arm’s-length benchmarks, creating a significant tax exposure that threatened the integrity of both IFRS and U.S. GAAP financial statements. The transfer-pricing team believed their calculations were solid, but when my team and I reviewed the underlying data, we discovered inconsistencies that would not withstand scrutiny.

I personally led a full recalculation from scratch. We rebuilt every intercompany transaction, benchmarked margins against comparable unrelated-party deals, and reconciled differences between IFRS and U.S. GAAP.

The result was a fully defensible position that eliminated the exposure entirely—protecting the company from what the document later quantified as more than $24 million in potential tax liability. This case perfectly illustrates the new reality: technical conflicts between accounting standards and tax law must be resolved proactively, with audit-grade documentation, because Pillar Two will only amplify any weaknesses.

Silicon Review: Your career includes building a shared-service center that cleared massive compliance backlogs across 30+ countries. How does that experience inform your approach today?

Haitham: The F2F (Financial To Filing)  remediation project I led shortly after joining GE was a turning point. We faced backlogs in corporate income tax filings, statutory accounts, central bank reports, and AGM documentation across the Middle East and Africa.

With a team of 50 professionals (now scaled to 70 across Cairo and Budapest), we created standardized operating procedures and a comprehensive “baseline pack” of audit requirements that harmonized inputs from dozens of different external auditors.

The foundation of our work included standardization, ownership at the territory level rather than in functional silos, and a relentless focus on quality.

Those principles remain the same today and help us handle Pillar Two data requirements and energy transition restructuring at scale.

Silicon Review: What advice would you give other tax leaders navigating 2026’s regulatory environment?

Haitham: Invest in your people and your data infrastructure. Pillar Two rewards those who can model scenarios quickly and accurately.

You should also stay deeply technical—never delegate the details entirely. It is also important to remember that compliance is about ensuring the entire global tax position tells a consistent, defensible story, as well as following the local rules and regulations.

The energy transition and Pillar Two are forcing us to rethink everything. The old blueprint of reconciling GAAP to local law is table stakes now. The real question in 2026 is: can your tax model survive a sudden drop in natural gas prices while the OECD changes the safe harbor rules mid-year?

Companies need to stop looking in the rearview mirror at past compliance wins and start simulating the fiscal impact of a green hydrogen plant in a country without yet having Pillar Two legislation. That's where the real exposure lives now.
