Stable and Predictable Revenue Business Model

As a provider of essential services, Ausnet operates in a highly regulated environment, with approximately 85% of total revenue subject to periodic price resets by the Australian Energy Regulator (AER), typically occurring every five years, providing stable and predictable earnings. In addition, the electricity distribution and transmission segments benefit from regulatory mechanisms that allow recovery of certain costs, including customer defaults, further enhancing earnings visibility.

The remaining 6% of revenue is derived from the unregulated Development & Future Networks business, which focuses on renewable energy and data centre infrastructure projects. Revenue is supported by directly negotiated long-term annuity-style contracts, providing recurring income that complements the group's regulated revenue base.

While regulated revenue is largely fixed during each five-year regulatory period, AusNet may apply for AER-approved cost pass-throughs for eligible unforeseen events. For example, the AER approved AUD30.1 million and AUD12.9 million in cost recoveries for restoration costs arising from the February and September 2024 Victorian storms, respectively. These mechanisms help mitigate the financial impact of extraordinary events, although recovery remains subject to AER approval and specified regulatory criteria.

Overall, AusNet's predominantly regulated revenue base and regulatory cost recovery mechanisms, provides strong earnings visibility and supports its resilient credit profile.

Predictable Revenue Supported by Regulatory Framework and Perpetual Asset Ownership

AusNet's core operational assets, including its electricity transmission, electricity distribution and gas distribution networks, are owned by the Group, with distribution licences held in perpetuity. This ownership and perpetual licensing structure ensures long-term control of the essential network infrastructure required for the Group's operations.

Revenue from the electricity transmission, electricity distribution and gas distribution businesses is regulated under five-year regulatory determinations by the Australian Energy Regulator (AER), providing a clear and predictable revenue path. As shown in Chart 1, AusNet's revenue composition has remained broadly stable over FY21–FY25, demonstrating the resilience and predictability of its earnings under the AER's regulatory framework.

Stable Earnings Despite Higher Financing Costs

Earnings stability is reflected in Ausnet’s operating margin, which has remained average 34% over the past five years. However, finance costs increased by 11% YoY to AUD 500 million, primarily due to higher market interest rates. The average interest rate on the Group’s outstanding borrowings rose marginally from 4.5% in the prior year to 4.6% in FY25 and total debt has increase 5% YoY to AUD 11.5 billion. Therefore, the interest coverage ratio dome in slightly lower at 1.68 times, But the bright side is that approximately 92% of its debt is fixed rate which minimises the exposure to interest rate risk. We opine that the finance cost is reined.

Steady rise in operating cash flow; capital-intensive nature elevates overall leverage ratio

Operating cash flow has steadily increased, in line with continued investment in utility infrastructure and expansion of the asset base. However, given the capital-intensive nature of the business, a substantial portion of assets is financed through debt, as reflected in a debt-to-asset ratio of 0.83 times. This is also evident in leverage metrics such as debt-to-operating cash flow of approximately 13 times. While leverage is relatively high, this is typical for regulated utilities given their stable cash flow generation and infrastructure financing requirements. Overall, we view the current debt level as manageable and within an acceptable range.

Manageable Refinancing Risk Supported by Regulated Revenue Framework

AusNet’s debt maturity profile, illustrated in Chart 1, is relatively front-loaded, with higher maturities concentrated between 2026 and 2030, averaging approximately AUD 1.3 billion per year. While committed credit facilities of AUD 1.1 billion and cash balances of AUD 7.4 million as at FY2025 are insufficient to fully cover upcoming maturities, the company is expected to refinance them in the near term and not forgetting that AusNet will also be riding on the credibility of its controlling company, Brookfield.

Refinancing risks are expected to be mitigated by AusNet’s substantial property, plant, and equipment base of approximately AUD 13.8 billion and strong operating cash flow AUD 869 million, combined with its regulated revenue framework, which provides stable and predictable cash flows under the AER-approved revenue recovery mechanism. Together, these factors support manageable leverage and adequate debt-servicing capacity.

Recommendation

Overall, AusNet is a regulated electricity distributor with ownership of essential energy infrastructure, providing stable and predictable revenue through long-term AER regulatory frameworks. Its strength lies in its stable, regulated cash flows, which support robust financial performance and manageable leverage. We view its bonds as a worthy consideration for investors seeking exposure to high-quality Australian utility bonds. Investors may consider the short- to medium-term bonds, which currently offer yields to maturity in the range of 5.0% to 5.9% (Table 4).

However, investors should note that ANVAU 6.134% 31 May 2033 Corp (AUD) carries an issuer call option, allowing the issuer to redeem the bond before maturity. In addition, the bond includes a Change of Control Event provision, which provides additional protection to bondholders by allowing them to require redemption if Brookfield’s control of TopCo falls below 40%, another party gains control, or TopCo ceases to control the Issuer and Guarantors, subject to certain exceptions. If triggered, the Issuer must redeem the notes within 15 Business Days; otherwise, the interest rate will increase once by 5.00 per cent. per annum.
