Highlights

  • TPG Telecom (ASX:TPG) reported improved mobile momentum and increased its Interim Dividend as subscriber growth supported earnings.
  • Aussie Broadband (ASX:ABB) delivered record FY2026 earnings, increased dividends and expanded its customer base following acquisitions.
  • Macquarie Technology Group (ASX:MAQ) continued investing in AI-linked data-centre capacity while extending its long EBITDA growth record.
  • Subscriber trends, infrastructure investment, margins and Capital discipline remain key themes across the telecommunications sector.

Australia’s telecommunications sector delivered a broad set of results during August 2026, and three companies highlight the different ways value is being created across the industry.

TPG Telecom (ASX:TPG) reported stronger mobile momentum and lifted its interim dividend. Aussie Broadband (ASX:ABB) posted record FY2026 earnings, increased its dividend and announced a buyback. Macquarie Technology Group (ASX:MAQ) continued expanding its data-centre footprint as Demand for cloud and AI infrastructure accelerated.

The common backdrop is a changing definition of telecommunications. The sector is moving beyond traditional connectivity toward mobile growth, enterprise services and the infrastructure required to support artificial intelligence. Investors are therefore assessing income-focused operators and capital-intensive infrastructure businesses through different lenses.

Why the Telecommunications Sector Is in Focus in September 2026

Telecommunications combines defensive income businesses with higher-growth infrastructure opportunities, creating different Investment dynamics across the sector.

Mobile services have become a key Earnings driver as operators focus on subscriber growth and average Revenue per user. Broadband remains competitive, with wholesale costs and pricing pressure influencing margins. At the same time, AI and cloud adoption are increasing demand for data-centre capacity, connectivity and digital infrastructure.

Key themes shaping sentiment include:

  • Mobile subscriber growth and ARPU trends
  • Data-centre demand linked to AI and cloud computing
  • Interest rates and their impact on dividends and infrastructure funding
  • NBN pricing, competition and broadband margins
  • Capital allocation and balance-sheet discipline

The result is a sector where investors are separating steady cash-generative businesses from companies investing heavily for future infrastructure growth.

Why TPG Telecom (ASX:TPG) Is in Focus

TPG Telecom (ASX:TPG), which operates brands including Vodafone, TPG, iiNet and felix, reported first-half 2026 results for the period ended 30 June 2026 on 21 August 2026.

Service revenue was about A$2,071 million, up 0.5% on a pro forma basis, while EBITDA increased 4.5% to around A$821 million. The EBITDA Margin improved to 33.9% from 32.1%, while NPATA increased to about A$70 million.

The strongest area was mobile. TPG Telecom (ASX:TPG) added around 64,000 net subscribers to reach 5.806 million, while mobile service revenue increased 3.1% to approximately A$1,224 million. Average revenue per user also improved slightly to A$35.21.

The company increased its interim dividend by 11.1% to 10.0 cents per share, reflecting stronger operating performance and its focus on Shareholder returns.

TPG Telecom (ASX:TPG) guided to FY2026 EBITDA of A$1,665–A$1,735 million and indicated expectations for a stronger second half. Following the divestment of enterprise, government and wholesale fixed-line infrastructure assets, the company is now more focused on mobile and consumer services.

The key areas to monitor are mobile growth, ARPU trends, competitive conditions and the sustainability of shareholder returns.

Why Aussie Broadband (ASX:ABB) Is in Focus

Aussie Broadband (ASX:ABB) has expanded from an NBN challenger into a broader connectivity provider spanning residential, business, enterprise, government, wholesale and mobile services.

Its FY2026 result, released on 24 August 2026, showed strong momentum. Revenue reached about A$1.295 billion, while underlying EBITDA increased 19.6% to a record A$165.1 million. Underlying net profit after tax rose about 25.8%.

The company increased its ordinary dividend by 50% on a fully franked basis and announced an on-market buyback of up to A$115 million.

Customer growth remained central. Broadband connections reached around 1.1 million after adding roughly 323,000 during the year, largely supported by the AGL Telco acquisition. Mobile connections also increased by around 48,000 to 263,000. Aussie Broadband (ASX:ABB) reported NBN Market Share of approximately 12.1%.

FY2027 guidance points to underlying EBITDA of A$205–A$215 million, implying continued growth. Connections are expected to exceed 1.3 million following completion of the AGL migration.

The key issue for Aussie Broadband (ASX:ABB) is whether it can maintain growth momentum while improving margins and integrating acquired customers effectively.

Why Macquarie Technology Group (ASX:MAQ) Is in Focus

Macquarie Technology Group (ASX:MAQ) represents a different telecommunications theme, with its focus increasingly linked to data centres, cloud services and AI infrastructure.

Its FY2026 result, released on 27 August 2026, showed revenue of about A$390 million, up 5.5%, while EBITDA reached A$115.9 million. Net profit after tax was about A$32.1 million. The result marked the company’s twelfth consecutive year of EBITDA growth, supported by approximately 95% of revenue coming from contracted monthly services.

The key development is IC3 Super West, the company’s flagship Macquarie Park data-centre project. Core and shell construction has been completed, with commissioning targeted for September 2026.

Beyond this, Macquarie Technology Group (ASX:MAQ) has acquired a 34,200-square-metre Macquarie Park site for a proposed Engineering & Technology Campus targeting around 200MW of additional capacity.

The company also received support from the Australian Government’s National Reconstruction Fund Corporation through A$200 million of perpetual subordinated securities, with A$100 million received and the balance expected by March 2027.

Capex is expected to increase materially as Macquarie invests in data-centre capacity, sovereign cloud capability and cyber security. Management expects only modest EBITDA growth in FY2027 as new capacity begins contributing.

The key focus is whether the company can convert infrastructure investment into contracted revenue while maintaining financial discipline.

What Connects These Three Stocks?

TPG Telecom (ASX:TPG), Aussie Broadband (ASX:ABB) and Macquarie Technology Group (ASX:MAQ) all operate within the broader telecommunications and digital-infrastructure ecosystem, but their strategies are very different.

TPG Telecom (ASX:TPG) is a large mobile-focused operator prioritising subscribers, service revenue and dividends. Aussie Broadband (ASX:ABB) is a growing connectivity challenger expanding across multiple customer segments. Macquarie Technology Group (ASX:MAQ) is effectively an infrastructure-growth company positioned around data centres and AI-related demand.

The differences are most visible in capital allocation. TPG Telecom (ASX:TPG) and Aussie Broadband (ASX:ABB) generate cash from customers and return capital through dividends and buybacks. Macquarie Technology Group (ASX:MAQ) is investing heavily in future capacity, accepting near-term capital intensity to capture longer-term AI and cloud opportunities.

Investors therefore watch these companies together as different expressions of the same theme: how connectivity infrastructure creates value in a more data-intensive economy.

What Could Move These Stocks Next?

  • TPG Telecom: FY2026 full-year performance, mobile subscriber growth, ARPU trends and dividend policy.
  • Aussie Broadband: Completion of the AGL migration, progress toward 1.3 million connections, EBITDA delivery and margin improvement.
  • Macquarie Technology Group: IC3 Super West commissioning, data-centre expansion, new contracts and funding progress.
  • Sector-wide: RBA policy, NBN developments, mobile competition and AI-driven infrastructure demand.

What Are the Risks?

TPG Telecom (ASX:TPG) faces mobile competition, broadband margin pressure and the challenge of sustaining growth following its Business reshaping.

Aussie Broadband (ASX:ABB) carries integration risk from acquisitions, margin pressure from competitive markets and execution risk around ambitious growth targets.

Macquarie Technology Group (ASX:MAQ) faces construction, commissioning and funding risks associated with large-scale data-centre expansion. Building capacity ahead of contracted demand also introduces utilisation risk.

Common risks include higher interest rates affecting infrastructure funding costs, regulatory changes, competitive pressure and the possibility that AI-related demand develops more slowly than expected.

What ASX Investors Should Watch Next

For TPG Telecom (ASX:TPG), the focus remains on whether mobile growth and improved margins can support sustainable shareholder returns.

For Aussie Broadband (ASX:ABB), investors will monitor whether customer growth translates into stronger profitability while the company completes integration projects and delivers on FY2027 guidance.

For Macquarie Technology Group (ASX:MAQ), execution is the key issue: bringing new data-centre capacity online, securing contracted revenue and managing capital requirements.

Across the sector, the next phase of telecommunications growth will likely be defined by the balance between reliable cash generation and investment in the infrastructure required for AI and cloud computing.
