Telecom Titans: How CFO Expertise Drives 5G Dominance and Global Growth

The telecom sector is undergoing a digital revolution, with 5G networks, AI integration, and broadband expansion reshaping the industry's future. Success hinges not only on technological prowess but also on financial leadership that can navigate regulatory complexity, capitalize on global markets, and align capital allocation with innovation. Two telecom giants—Advanced Info Service (AIS) in Thailand and Vodafone Group in Europe—are exemplifying this dynamic through their CFO transitions. Let's dissect how their choices in financial stewardship could spell the difference between sustainable growth and falling behind.

AIS: A CFO with Telecom DNA Powers Thailand's 5G Surge

AIS, Thailand's dominant telecom player, has leaned on Mr. Montri Khongkruephan, its CFO since 2023, to steer its digital transformation. Khongkruephan's career is steeped in telecom and audit expertise: after a decade at Deloitte advising on regional accounting for Southeast Asian telecom firms, he joined AIS in 2021 as Head of Audit, then ascended to CFO. His tenure has been marked by aggressive CAPEX spending—Bt 26-27 billion allocated in 2025—to expand 5G coverage to 95% of Thailand's population and bolster AIS 3BB's fiber broadband network (now serving 5 million subscribers).

Investors have rewarded this strategy: AIS's net profit rose to Bt 35.075 billion in 2024, up 14% year-on-year, while its stock (ADVANC.BK) has outperformed regional peers amid steady revenue growth.

Khongkruephan's audit background ensures AIS stays compliant in a tightly regulated market. His focus on cost discipline—evident in trimming operational inefficiencies—aligns with AIS's goal to become a “Cognitive Tech-Co,” integrating AI into customer service and network management.

Vodafone: A Tech CFO Transition for Global Dominance

Vodafone's shift from Luka Mucic to Pilar López signals a pivot toward tech-driven global expansion. Mucic, ex-SAP CFO, left in late 2025 after overseeing asset sales in Spain/Italy and securing regulatory clearance for its UK merger with Three. His successor, López—a former Microsoft COO for Western Europe and Telefónica's ex-CFO—brings deep telecom and tech acumen.

López's mandate: accelerate operational simplification and Africa expansion. Vodafone aims to double its African financial tech business, which processed over 1 billion transactions in 2024, while slashing bureaucracy in Europe. Her prior experience at Microsoft and Telefónica positions her to leverage AI in network optimization and customer analytics.

Vodafone's stock (VOD) has lagged peers in recent years due to operational challenges in Germany and Italy. López's success will hinge on delivering free cash flow growth, which rose 5% in 2024 but remains below peers like AT&T.

Why CFO Telecom Expertise Matters—And What's at Stake

Both AIS and Vodafone exemplify the telecom-CFO synergy:
1. Risk Mitigation: Khongkruephan's audit expertise helps AIS avoid regulatory missteps in Thailand's competitive market. López's Telefónica background equips her to navigate Europe's stringent data privacy laws.
2. Capital Allocation: Telecom's high CAPEX needs demand CFOs who can prioritize 5G, fiber, and AI without over-leveraging. AIS's CAPEX-to-revenue ratio (12%) is sustainable, while Vodafone's African expansion requires Lopez to balance growth with profitability.
3. Global vs. Local Focus: AIS targets Thailand's saturated market through AI-driven services, while Vodafone bets on Africa's untapped potential—both strategies need CFOs fluent in regional regulatory and competitive dynamics.

Investment Implications: Betting on CFO-Driven Telecom

Opportunities:
- AIS (ADVANC.BK): A buy for investors betting on Thailand's 5G adoption and broadband dominance. Monitor its CAPEX execution and free cash flow trends.
- Vodafone (VOD): A long-term play if López can stabilize European operations and monetize Africa's fintech.

Risks:
- Misaligned Leadership: CFOs without telecom experience could misallocate CAPEX (e.g., overinvesting in legacy infrastructure).
- Regulatory Headwinds: Poor governance could trigger fines or delays in mergers (e.g., Vodafone's UK deal).

Watch for Vodafone's stock reaction to López's strategic moves. A sustained rise post-2025 could signal investor confidence in her vision.

Final Takeaway

In telecom's digital age, CFOs are no longer just number-crunchers—they're architects of innovation and growth. Companies like AIS and Vodafone, with CFOs deeply embedded in telecom's complexities, are better positioned to win in 5G, AI, and global markets. Investors should prioritize firms where financial leadership marries tech know-how with strategic vision. For others? The risks of falling behind are too great.
