Telstra's Outage Lands In The Middle Of A Valuation Standoff

A nationwide mobile outage tested Telstra's defensive reputation in July 2026. Pendal Group reported the disruption affected voice, data and SMS services and, most seriously, prevented some users from reaching Triple Zero emergency services, with the fault reportedly traced to a malfunctioning timer in two data-centre servers. The company faces regulatory investigation and is conducting welfare checks on affected customers, though the manager noted large-scale telco outages have historically had limited long-term impact on market share or earnings.

A valuation debate splitting managers three ways

That incident landed in the middle of an already active debate about how much to pay for Telstra's defensive earnings. Investors Mutual Limited rated the stock a hold in June 2026, saying its thesis is playing out well as the mobile market becomes more rational and Optus moves toward covering its cost of capital, but that at 24 times price-to-earnings it was not prepared to chase the stock higher. Plato Investment Management took the opposite side, rating it a buy and arguing that despite the higher valuation, Telstra still looks decent value against comparable stocks and has room to keep growing its dividend given cash flow running ahead of accounting earnings. Ten Cap rated it an outright sell, arguing investors are paying close to 25 times earnings for a low-growth defensive business, and flagging the longer-term threat from Starlink and other satellite technologies as a real risk to the industry structure once markets refocus away from geopolitical concerns.

Results built on cash flow outpacing accounting profit

The rally that pushed the valuation debate into focus was built on genuinely strong first-half FY26 results. Pendal Group reported Telstra unexpectedly increased its dividend to 10.5 cents per share versus 10 cents expected, with management signalling the payout will not be restricted to being fully franked, allowing it to keep growing over time given cash profits running well ahead of accounting profit. The company also lifted its buyback from $1 billion to $1.25 billion, with cash EBIT expected to grow more than 12 per cent for the year. Perpetual Asset Management explained the mechanics behind the gap between cash and accounting profit, noting the company is depreciating assets at a faster rate than it is spending on new capital expenditure, having identified efficiencies that let capex decline even as mobile subscribers grew 5 per cent in the period.

A steady stream of profit-taking

Several managers used the strength through early 2026 to trim rather than add. Pengana Capital Group repeatedly described taking profits in Telstra through February and March, describing higher dividends and buybacks as the ultimate proof point of improving returns before recycling capital elsewhere. Ten Cap and Perennial Partners both took profits in May 2026, with Perennial Partners redirecting proceeds into insurer IAG as an alternative defensive beneficiary of rising rates, while Paradice Investment Management exited entirely in the June quarter following strong outperformance, expressing a preference for supermarkets as its defensive exposure of choice.

What managers are watching next

With the July 2026 outage now under regulatory review and satellite competition from providers like Starlink cited by bears as a longer-term structural risk, the key questions for managers are whether the incident triggers any material regulatory penalty or customer churn, and whether Telstra's cash-flow-led dividend growth story can continue justifying a valuation multiple that has already prompted several long-term holders to reduce their positions.
