How did Optus perform financially in the 12 months ended March 31?

Optus delivered strong financial growth, with total revenue rising 2.1 per cent to $8.35 billion. Earnings before interest, taxation, depreciation, and amortisation (EBITDA) climbed 6 per cent to $2.36 billion.

Did the September 2025 Triple Zero outage hurt the financial results of Optus?

No, the devastating Triple Zero network outage did not significantly damage the telco's annual financial performance. Operational revenue and earnings remained resilient, largely unblemished by the crisis.

What drove the 6 per cent EBITDA growth for Optus?

The earnings boost was primarily driven by a landmark regional network-sharing agreement with TPG Telecom (ASX:TPG) alongside mobile price hikes. Operational discipline and tight expense management also supported margins.

How did the network-sharing deal with TPG Telecom (ASX:TPG) impact Optus?

The agreement served as a primary driver of fiscal growth, generating steady commercial revenue as TPG paid to access the Optus regional mobile infrastructure. The partnership allows both telcos to better challenge Telstra's historical dominance in regional Australia.

What are the key bull points for Optus following these annual results?

The main bullish indicators are rising average revenue per user via a 2.7 per cent bump in mobile revenue and a 4.1 per cent expansion in wholesale and enterprise segments. Additionally, the network-sharing deal with TPG Telecom provides a predictable, recurring revenue stream.

What are the key bear points and risks for Optus investors to watch?

Rising baseline expenses remain a concern, as staff and network operational costs rose 1.6 per cent during the financial year. There is also ongoing headline risk regarding regulatory scrutiny and consumer sentiment following the Triple Zero infrastructure failure.

Optus defies outage crisis to post strong earnings

Written by Heidi Cuthbert Published May. 21 2026Last Updated May. 21 2026

Optus has emerged from a tumultuous period to post solid financial gains, largely unblemished by the devastating Triple Zero network outage that struck the telecommunications provider last September 2025.

According to annual results released by Singaporean parent company Singtel for the twelve months ended March 31, the Australian telco generated $8.35 billion in revenue, representing a 2.1% increase.

Driven by structural changes and strategic partnerships, earnings before interest, taxation, depreciation, and amortisation (EBITDA) climbed 6% to $2.36 billion, whilst total business expenses experienced a marginal 0.6% uptick to $6.13 billion.

The positive financial momentum marks a successful inaugural full financial year for CEO Stephen Rue, who stepped into the leadership role following a period of intense public scrutiny.

Rue credited the turnaround to internal reforms, stating that the figures reflect a more disciplined business focused heavily on lifting operational benchmarks and prioritising customer service.

A primary driver of the fiscal growth was a landmark, regional network-sharing agreement struck a year ago with TPG Telecom (ASX:TPG), the owner of Vodafone.

This deal allowed TPG to pay for access to the Optus regional mobile infrastructure in a collaborative bid to challenge Telstra’s dominance in regional Australia.

Mobile revenue grew by 2.7% following strategic price increases, and wholesale and enterprise segments expanded by 4.1%.

Although staff and network operational costs rose 1.6%, these expenses were offset by the well-timed divestment of the Optus Sport platform.
