Revenue growth appears robust at 39.2% in 2026Q2, but operating margin has compressed to 13.2% from a peak of 16.5% in 2025Q3, suggesting cost inflation is outpacing pricing power.

Hyperinflation accounting distorts performance
Revenue Growth Distorted by Accounting Framework
The reported -96.8% revenue growth in 2025Q4 is a direct artifact of IAS 29 hyperinflationary accounting, not an operational collapse, as subsequent quarters show a return to nominal growth of 39.2% and 42.6%.
The extreme volatility in reported revenue growth, swinging from -96.8% to +42.6% quarter-over-quarter, is a hallmark of the IAS 29 restatement process in a hyperinflationary economy like Turkey. This accounting framework resets the monetary base each period, making year-over-year comparisons of nominal figures misleading for assessing underlying demand trends. Investors must look past these distortions to the company's ability to grow real ARPU and maintain subscriber volumes, which are the true indicators of its revenue recovery trajectory.
Operating Margin Compression Amid Inflation
Operating margin has compressed from a peak of 16.5% in 2025Q3 to 13.2% in 2026Q2, suggesting that cost inflation, particularly in energy and labor, may be outpacing the company's ability to adjust pricing in its regulated and semi-regulated service contracts.
The decline in operating margin from the mid-teens to 13.2% indicates that the high fixed-cost structure of the telecom network is becoming a liability in the current inflationary environment. While revenue is growing nominally, the cost of operating base stations and maintaining infrastructure appears to be repricing faster than consumer tariffs can be adjusted. This margin erosion warrants monitoring, as it suggests the company's earned return on its invested capital may be falling below its cost of capital, despite top-line growth.
Energy Costs as a Structural Margin Headwind
The significant depreciation and amortization expense, which reached $21.1B in 2026Q2, represents a major non-cash cost that, combined with rising energy prices for base station operations, is a primary driver of the observed operating margin compression.
For a capital-intensive telecom operator, the D&A line is a proxy for the ongoing cost of maintaining and upgrading the network. The sharp increase in this expense suggests recent heavy investment, but the corresponding margin decline implies that the revenue generated from this new capacity is not yet fully covering its associated operating costs. This dynamic is critical, as it indicates that cost recovery through pricing is lagging, potentially due to competitive pressures or regulatory constraints on tariff increases.
Net Income Volatility Masks Core Earnings
The erratic net income trajectory, including a $14.3B spike in 2024Q3 followed by a return to the $3-5B range, suggests significant non-recurring items or hyperinflationary adjustments that obscure the durability of the core regulated earnings stream.
The quality of reported earnings is highly questionable given the extreme volatility. The 2024Q3 net income spike, which resulted in a 35.5% net margin, is almost certainly driven by a one-time monetary gain or accounting adjustment under IAS 29, not operational performance. Excluding such periods, the underlying net margin appears to settle in the 6-8% range, which is more representative of the sustainable earnings power from the core telecom and fintech operations.
Capital Intensity Without Clear Margin Payoff
The persistent high D&A expense, consistently exceeding $12B per quarter, indicates a sustained heavy capital investment cycle, yet the lack of corresponding margin expansion suggests this CAPEX is primarily maintenance-oriented or failing to generate incremental returns.
The capital expenditure cycle, as reflected in D&A, is clearly elevated. However, the failure of operating margins to expand—and their recent compression—raises questions about the return on this invested capital. In a regulated or semi-regulated utility context, this pattern suggests that new investments are either not yet fully earning their allowed return due to regulatory lag, or are being deployed into segments (like international operations) with lower profitability. The current trajectory does not indicate a step-change in earnings growth from CAPEX.
Hyperinflation Accounting Masks Operational Strength
The strongest challenge to the negative margin narrative is that the reported financials are fundamentally distorted by IAS 29, and the company's ability to grow nominal revenue by over 40% in recent quarters demonstrates strong underlying pricing power and demand resilience.
An analyst focusing solely on the declining operating margin may miss the forest for the trees. The core counter-argument is that in a hyperinflationary environment, nominal growth is the primary indicator of survival and market position. TKC's ability to post 39-42% revenue growth suggests it is successfully passing through significant cost inflation to its subscriber base, a feat not all competitors can achieve. The margin compression may be a temporary artifact of the accounting reset process rather than a permanent impairment of the business model's economics.
