# Return on capital: judging whether the network investment pays off
Verizon spends roughly $18 billion a year on capital expenditurecapital expenditureCapital Expenditure (CapEx) is money spent to acquire, upgrade, or extend long-lived assets like equipment, property, or software that deliver value over multiple years.Voir la définition complète →. Deutsche Telekom and its peers across Europe collectively pour tens of billions more into fiber trenches and 5G radios every year. The question every investor, regulator, and board member should ask is simple: does that spending actually generate returns above what it cost to raise the money? Most telecom coverage focuses on revenue growth or subscriber counts. Return on capital metrics answer a harder, more important question: is the business creating value, or just building expensive infrastructure that never pays for itself?
This is the metric that separates disciplined operators from what industry veterans call "empire builders": management teams that chase network coverage or spectrum trophies without regard for whether the investment clears its cost of capital.
Telecom is one of the most capital-intensive industries in the economy. Building and maintaining fiber networks, cell towers, spectrum licenses (government-granted rights to use specific radio frequencies), and data centers requires continuous, massive spending.
CapEx (capital expenditure) as a share of revenue typically runs 15% to 20% for telecom operators, compared to low single digits for most software or retail companies. That capital gets locked up for decades. A fiber cable laid today might still be earning revenue in 2050. This makes return on capital the defining discipline in the sector: get it wrong and you can destroy shareholder value even while growing revenue.
ROIC measures how efficiently a company turns the capital invested in the business (debt plus equity, minus excess cash) into operating profit.
Formula:
ROIC = NOPAT / Invested Capital
Where:
ROCE is a close cousin, widely used in European financial reporting, that measures return relative to capital employed in the business.
Formula:
ROCE = EBIT / Capital Employed
Where:
The two metrics tell a similar story but ROCE is a pre-tax, simpler cousin often preferred in European filings (it appears regularly in Vodafone and Deutsche Telekom investor materials), while ROIC is more common in US equity analysis and factors in tax effects directly.
Neither ROIC nor ROCE means anything in isolation. You compare it against the WACC (Weighted Average Cost of Capital): the blended cost of a company's debt and equity financing, representing the minimum return needed to satisfy investors and lenders.
The rule: ROIC > WACC means the company creates value with every dollar invested. ROIC < WACC means it destroys value, even if the accounting profit looks fine.
For telecom operators in 2026, WACC estimates typically run in the range of 6% to 8% in the US and 5% to 7% in Europe (these vary by company risk profile, leverage, and interest rate environment, and should be treated as estimates rather than precise figures). European WACC tends to run slightly lower due to generally lower government bond yields underpinning the risk-free rate.
Let's build a simple calculation using rounded, illustrative figures (not any specific real company's actual reported numbers).
Assume "EuroTel," a mid-sized European operator:
Step 1: Calculate NOPAT
NOPAT = €4.0 billion x (1 − 0.25) = €3.0 billion
Step 2: Calculate Invested Capital
Invested Capital = €25 billion + €20 billion − €3 billion = €42 billion
Step 3: Calculate ROIC
ROIC = €3.0 billion / €42 billion = 7.1%
Step 4: Compare to WACC
If EuroTel's WACC is estimated at 6.5%, its ROIC of 7.1% sits modestly above the cost of capital. It's creating value, but the margin is thin. If WACC rises to 7.5% (say, due to higher interest rates raising the cost of debt), that same 7.1% ROIC now signals value destruction.
This is exactly why telecom executives watch bond yields closely. A capital-intensive business with thin ROIC spreads is highly sensitive to financing costs.
The takeaway from these ranges: many telecom operators run close to, or barely above, their cost of capital. This is a structurally thin-margin-on-capital industry, unlike, say, software companies that can post ROIC well above 20%.
For a deeper primer on the mechanics, the CFA Institute's overview of ROIC and economic value concepts is a solid free reference point for the underlying corporate finance theory.
When a European operator announces a new multi-billion-euro fiber-to-the-home rollout, or a US carrier bids in a spectrum auction run by the FCC (Federal Communications Commission), analysts immediately ask: what's the expected ROIC on this specific investment, and will it plausibly exceed WACC within a reasonable payback period?
This is why some operators pursue network sharing (splitting infrastructure costs with a competitor) or spin off tower assets into separate companies (as Vodafone did with Vantage Towers, and as several US carriers have done with tower sale-leasebacks). Removing capital-heavy, lower-return assets from the core balance sheet can lift group-level ROIC even if it doesn't change the underlying network economics.

A single year's ROIC tells you less than the trend. Rising ROIC over several years, even from a low base, suggests capital discipline is improving: management is being more selective about which network investments it approves, retiring old debt, or improving operating margins per dollar deployed.
