5G Expansion And IoT Integration Will Unlock Telecom Potential

Key Takeaways

• Strong 5G leadership and growth in digital, IoT, and financial services are strengthening TIM's revenue diversity and supporting sustained earnings improvement.
  
• Efficiency gains from network modernization, cost control, and increased postpaid customer mix are driving higher margins, cash flow, and shareholder returns.
  
• Stagnant fixed-line business, rising competition, infrastructure cost risks, and challenges in the prepaid segment threaten revenue growth, margin expansion, and overall earnings resilience.

Catalysts

A telecommunications company, provides mobile, fixed, long-distance, data transmission, and broadband services in Brazil.

• The rapid expansion and adoption of 5G-including covering 70% of Brazil's urban population, achieving #1 in 5G cities, and the shift of 30%+ of traffic to 5G-positions TIM to benefit from rising data consumption, unlock higher ARPU, and improve net margins due to lower cost per gigabyte and premium service upcharges.
  
• Sustained growth in new revenue streams such as IoT (notably in B2B verticals like logistics, agribusiness, utilities) and expansion into digital/financial services (via partnerships like Eletrobras and upcoming financial service launches) diversifies and expands TIM's revenue base, supporting future topline growth and improved earnings quality.
  
• Ongoing network modernization programs and the use of artificial intelligence for operational efficiency, combined with aggressive tower contract renegotiations and potential infrastructure sharing, are driving material opex and capex savings, which should support further margin expansion and higher free cash flow.
  
• Increased penetration of stable, higher-value postpaid customers (now nearly 70% of mobile service revenues) and sequential ARPU growth point to improving revenue visibility, lower churn, and resilience against commoditization pressures-supporting the sustainability of earnings.
  
• Disciplined cost control initiatives-including digitalizing sales, internalizing e-commerce, and focusing on multi-channel presence-are enabling TIM to keep costs below inflation while boosting efficiency, with direct positive impacts on earnings growth and the company's ability to increase shareholder returns.

TIM Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming TIM's revenue will grow by 4.6% annually over the next 3 years.
• Analysts assume that profit margins will increase from 13.9% today to 19.7% in 3 years time.
• Analysts expect earnings to reach R$5.9 billion (and earnings per share of R$2.43) by about August 2028, up from R$3.6 billion today. However, there is some disagreement amongst the analysts with the more bearish ones expecting earnings as low as R$4.9 billion.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 15.5x on those 2028 earnings, up from 14.5x today. This future PE is greater than the current PE for the US Wireless Telecom industry at 14.3x.
• Analysts expect the number of shares outstanding to decline by 0.12% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 17.8%, as per the Simply Wall St company report.

TIM Future Earnings Per Share Growth

Risks

• The company's fixed-line business remains stagnant with no inorganic progress and faces a competitive scenario, signaling ongoing headwinds in this segment; any divestment or inability to scale fixed operations could limit growth opportunities and negatively impact overall revenue diversification and long-term earnings.
  
• Regional competition is intensifying, particularly from aggressive new entrants in markets like Northeast Brazil, which may lead to increased price pressure and reduced ability to sustain high ARPU (Average Revenue Per User), directly threatening revenue growth and net margins.
  
• High dependence on physical infrastructure and ongoing negotiations with tower companies pose cost risks-failure to secure favorable lease terms or delays in decommissioning expensive towers could keep operating expenses elevated, undermining margin expansion and overall profitability.
  
• Sustained increase in network and interconnection costs-driven by higher international roaming and provider expenses-may erode operational leverage, and if not matched by equivalent revenue increases, could compress EBITDA margins and limit net income growth.
  
• Despite strong postpaid momentum, the prepaid segment faces structural decline, and while efforts to migrate customers to higher-value plans exist, long-term saturation or loss of low-income customers could constrain organic subscriber growth, putting pressure on top-line revenue and limiting overall earnings resilience.

Valuation

• The analysts have a consensus price target of R$23.021 for TIM based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of R$26.3, and the most bearish reporting a price target of just R$19.0.
  
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be R$29.8 billion, earnings will come to R$5.9 billion, and it would be trading on a PE ratio of 15.5x, assuming you use a discount rate of 17.8%.
  
• Given the current share price of R$21.67, the analyst price target of R$23.02 is 5.9% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
