Digital infrastructure investment in EMEA requires distinct approaches by sub-region. While European FiberCos trade at 10–12x EBITDA with stable regulatory frameworks, North African markets (Morocco, Tunisia) demand currency-hedged DCF models and regulatory scenario planning.

EXXING's experience spans EMEA infrastructure: Morocco fiber masterplanning (EXXING #69–75), North African data center due diligence (EXXING #28), and European wholesale fiber analysis (extrapolated from Morocco regulatory benchmarks). This article focuses on Morocco and Tunisia, where we have direct project experience, with selective EMEA comparisons where regulatory parallels exist.

Key insight: Morocco's ANRT regulation (cost-oriented wholesale pricing, infrastructure sharing mandates) mirrors European models more than Sub-Saharan African markets. This makes Moroccan FiberCo valuation techniques portable to Southern Europe, but not to West Africa where regulatory frameworks differ fundamentally.

The Investment Case for Passive Infrastructure

Passive telecommunications infrastructure (towers, fibre) presents unique characteristics for institutional investors seeking stable, inflation-protected returns with operational upside potential.

Asset Class Characteristics

CharacteristicTowerCosFiberCosInvestor Advantage
Contract duration10-15 years15-25 yearsCash flow visibility
Inflation indexation95% of contracts85% of contractsPurchasing power protection
Occupancy potential1.8-2.5 tenants/tower30-60% take-upSignificant operational upside
Maintenance CAPEX8-12% of revenue15-20% of revenueHigh cash conversion
Economic correlationLow (essential services)MediumRecession resilience

These characteristics explain why infrastructure funds have allocated increasing capital to the sector. However, theoretical advantages encounter complex operational realities in emerging markets.

Market Context

The African digital infrastructure market presents a compelling investment thesis:

MetricAfrica (2024)Europe (2024)Gap
Mobile penetration46%118%72pp
Fixed broadband penetration2%34%32pp
Tower tenancy ratio1.82.50.7
Fibre homes passed12M180M15x
Annual infrastructure investment$8B$45B5.6x

The infrastructure deficit creates substantial growth opportunity, but realising that opportunity requires navigating significant operational and financial risks.

Valuation Framework

Traditional EBITDA multiples (8-12x in developed markets) can be misleading in contexts of high currency volatility and regulatory uncertainty. EXXING advocates a rigorous Discounted Cash Flow (DCF) approach, complemented by sensitivity analysis across six critical variables.

DCF Methodology for Infrastructure

The DCF framework for infrastructure assets requires specific adaptations:

Revenue Projection: Build from contract-level analysis, incorporating:

  • Existing contract terms (duration, escalation, renewal probability)
  • New tenant/customer acquisition assumptions
  • Churn and contract renegotiation risk

Cost Structure: Distinguish between:

  • Fixed costs (land lease, security, basic maintenance)
  • Variable costs (power, tenant-specific equipment)
  • Growth CAPEX versus maintenance CAPEX

Terminal Value: Apply conservative assumptions given:

  • Technology risk (5G densification may reduce tower demand)
  • Regulatory risk (infrastructure sharing mandates)
  • Competition risk (new entrants, alternative technologies)

Critical Variables for Sensitivity Analysis

VariableTowerCosFiberCosValuation Impact
Tenancy ratio1.8 → 2.3N/A+25% EV
Take-up rateN/A35% → 50%+40% EV
Annual churn3% → 8%12% → 18%-15% EV
Currency depreciation5%/year → 10%/year5%/year → 10%/year-20% EV
WACC12% → 15%13% → 16%-18% EV
Exit multiple10x → 8x9x → 7x-12% EV

Tenancy Ratios (TowerCos)

The co-location ratio per tower is the primary value driver for TowerCos. In African markets, the average is 1.8 tenants per tower compared to 2.5 in Europe. Each additional tenant generates incremental margin of 75-85% due to low marginal operating costs.

Common Error: Projecting linear tenancy growth without analysing MNO (Mobile Network Operator) capital expenditure plans. EXXING recommends:

  1. CAPEX plan audit: Review published investment budgets of listed MNOs
  2. Geographic analysis: Urban zones (tenancy 2.5+) versus rural (1.2-1.5)
  3. Anchor site mapping: Identify sites near highways, shopping centres with high co-location potential

Case Study: West African TowerCo

EXXING advised on a 2,500-tower portfolio acquisition in West Africa:

MetricSeller ProjectionEXXING AssessmentVariance
Current tenancy1.751.75
Year 5 tenancy2.402.15-10%
Revenue CAGR12%9%-3pp
EBITDA margin Y568%64%-4pp
Implied EV adjustment-18%

The variance arose from over-optimistic assumptions about 5G rollout timing and MNO consolidation effects.

Take-Up Rates (FiberCos)

The distinction between homes passed (premises with fibre availability) and homes connected (subscribing premises) is critical. A FiberCo may report 500,000 homes passed but only 150,000 connected (30% take-up).

Regional Benchmarks:

MarketTake-Up RateKey Drivers
South Africa45-55%Mature market, weak DSL competition
Nigeria25-35%Emerging market, strong 4G competition
Kenya35-45%High urban penetration, Safaricom Fibre
Morocco40-50%Government subsidies, Morocco Telecom network

Take-Up Drivers:

  1. Affordability: Price below 5% of median household income
  2. Quality perception: Latency and stability versus 4G/5G
  3. Network density: Points of Presence reducing last-mile distance
  4. Content availability: Streaming services driving demand

Churn and Revenue Predictability

In prepaid-dominant markets (80%+ of mobile subscribers in Africa), churn is structurally higher than in contract-based developed markets.

SegmentAnnual ChurnKey Factors
Mobile prepaid45-65%Price sensitivity, coverage, promotions
Mobile postpaid15-25%Contract lock-in, credit requirements
Enterprise fibre8-15%Contract duration, switching costs
Residential fibre18-28%Competition, service quality

Implication: Revenue projections must incorporate realistic churn assumptions and customer acquisition costs to maintain subscriber base.

Currency and Country Risk

Currency Risk Management

Emerging market infrastructure investments face significant currency risk. Local currency revenues must service USD or EUR-denominated debt and generate returns for international investors.

Hedging Strategies:

StrategyCostEffectivenessApplicability
Natural hedge (USD revenues)LowHighEnterprise/wholesale segments
Forward contracts3-8% p.a.MediumShort-term, liquid currencies
Cross-currency swaps4-10% p.a.HighLong-term, limited availability
Inflation indexationBuilt into contractsPartialAddresses local inflation, not FX

EXXING Recommendation: Structure transactions with USD-denominated anchor contracts (international MNOs, enterprise customers) covering at least 40% of revenue to create natural currency hedge.

Country Risk Assessment

EXXING's country risk framework evaluates:

MacroeconomicInflation, currency stability, sovereign credit rating25%
PoliticalGovernment stability, policy continuity, rule of law20%
OperationalPower availability, security, skilled labour15%
MarketCompetition intensity, growth potential, customer concentration10%

Risk-Adjusted WACC: Country risk premium typically adds 3-8 percentage points to developed market WACC for African infrastructure investments.

Value Creation Strategies

Operational Excellence

Post-acquisition value creation focuses on:

Energy Optimisation: Power costs represent 25-40% of TowerCo operating expenses in Africa. Strategies include:

  • Solar/battery hybrid systems (30-50% cost reduction)
  • Power purchase agreements with independent producers
  • Smart metering and theft reduction

Maintenance Efficiency: Preventive maintenance programmes reduce:

  • Unplanned downtime (SLA penalties)
  • Emergency repair costs
  • Tenant churn from service quality issues

Tenant Management: Active relationship management to:

  • Identify co-location opportunities
  • Negotiate contract renewals
  • Cross-sell additional services (power, security, maintenance)

Portfolio Optimisation

Geographic Rationalisation: Divest low-potential rural sites; reinvest in high-growth urban corridors.

Technology Upgrade: Prepare sites for 5G densification requirements (power capacity, structural strength, fibre backhaul).

Consolidation: Acquire smaller portfolios to achieve scale economies in operations and procurement.

Exit Preparation

Documentation: Maintain comprehensive site-level data for due diligence.

Contract Quality: Extend and improve anchor tenant contracts before exit.

Operational Metrics: Demonstrate consistent improvement in KPIs (tenancy, uptime, cost efficiency).

Case Study: Pan-African TowerCo Investment

EXXING advised a European infrastructure fund on a $180 million investment in a pan-African TowerCo with operations in four countries.
