Saunders International to acquire Aqua Metro for A$30m in water infrastructure expansion push

How will Saunders International’s Aqua Metro acquisition reshape its water sector expansion and drive stable earnings through long-term utility contracts?

Saunders International Limited (ASX: SND) has moved decisively to strengthen its water infrastructure portfolio, agreeing to acquire Victoria-based water engineering specialist Aqua Metro Pty Ltd and associated entities for up to AUD 30 million.

The acquisition, announced on 15 July 2025, represents a strategic shift for the multidisciplinary engineering and construction group as it seeks to diversify its revenue base and secure long-term earnings from annuity-style contracts with utilities and government agencies. Completion is targeted for the first quarter of FY2026, subject to standard closing conditions, including change-of-control consents for Aqua Metro’s key contracts and consultation with the Australian Securities Exchange under Listing Rules 11.1.

The deal structure includes an initial payment of AUD 11 million in cash and AUD 7 million in equity, followed by a potential performance-based earn-out of up to AUD 12 million. The earn-out will be calculated based on a four-times EBIT multiple averaged across FY2025 and FY2026. All equity components are subject to a 12-month escrow, with shareholder approval scheduled for Saunders International’s Annual General Meeting later this year.

Institutional investors welcomed the announcement, with Saunders International’s stock gaining 6% to close at AUD 0.795 on the day of the deal, reflecting early confidence in the strategic rationale. Analysts described the move as a “logical diversification” away from traditional engineering and industrial contracts, highlighting its alignment with the company’s long-term strategy to secure stable, infrastructure-linked revenue streams.

Why is the Aqua Metro acquisition seen as a strategic shift for Saunders International’s growth and earnings profile?

Aqua Metro is one of Victoria’s leading water infrastructure contractors, specialising in hydraulics, mechanical and civil engineering, pipeline rehabilitation, and wastewater treatment plant construction. The business holds positions on four major Victorian water authority framework panels, with expiry terms extending through to 2028. Aqua Metro has delivered more than 300 projects and employs a workforce of over 100 professionals, many of whom are expected to transition into Saunders International’s operations post-acquisition.

The financial outlook for Aqua Metro explains why this acquisition is viewed as transformative. For FY2025, the business is forecast to deliver AUD 102 million in revenue and AUD 8.2 million in EBITDA, increasing to AUD 135 million in revenue and AUD 11 million in EBITDA by FY2026. Its growth trajectory is supported by a AUD 411 million order book (work in hand) and a pipeline exceeding AUD 1.4 billion, including secured and anticipated projects under existing framework agreements extending through to FY2031. Analysts have pointed out that the high proportion of government clients—estimated at 96% of Aqua Metro’s portfolio—offers the kind of earnings stability that institutional investors increasingly value in the infrastructure sector.

Saunders International expects to leverage Aqua Metro’s strong relationships with government utilities to unlock cross-selling opportunities. By combining Aqua Metro’s design and water sector project management capabilities with Saunders International’s expertise in tank construction, industrial automation, and pipework, the merged entity aims to offer end-to-end water infrastructure solutions. Institutional investors anticipate that these synergies, if realised, could drive margin expansion over the next 18 to 24 months.

How does this deal position Saunders International within Australia’s evolving water infrastructure market?

The acquisition comes at a time when Australia’s water and wastewater infrastructure sector is undergoing significant expansion. Valued at approximately AUD 8.9 billion in FY2024, the sector is projected to grow steadily through 2030, fuelled by population increases, climate-driven water security concerns, and regulatory pressure to upgrade ageing infrastructure.

Victoria, Aqua Metro’s home market, accounts for around 77% of state water infrastructure capital expenditure. Melbourne Water Corporation alone has committed AUD 6.8 billion between FY2024 and FY2028 to enhance water reliability. Aqua Metro is well positioned within this environment, having secured key framework agreements with major Victorian water authorities.

Outside Victoria, national opportunities are also compelling. Queensland has committed AUD 1.7 billion to water infrastructure planning, while Sydney Water’s 10-year capital and operational program forecasts AUD 34 billion in expenditure, averaging AUD 3.4 billion annually. Saunders International’s management has hinted that the acquisition could serve as a platform for national expansion, particularly in New South Wales and Queensland, where its existing relationships in defence and industrial infrastructure could provide a competitive edge.

From an ESG perspective, water security is increasingly seen as a critical infrastructure priority, and institutional investors are actively seeking exposure to companies operating in this space. By acquiring a proven operator like Aqua Metro, Saunders International could improve its profile as a reliable infrastructure services partner to utilities and government agencies.

What are the key risks and integration challenges, and how are investors viewing them?

Despite the positive market reaction, analysts have flagged execution risks. Aqua Metro’s strong earnings are dependent on long-term framework agreements with government utilities. Any delay in contract renewals, unfavourable renegotiations, or shifts in procurement policy could undermine revenue visibility. Additionally, Saunders International will inherit Aqua Metro’s historical liabilities post-acquisition. Without warranty and indemnity insurance, unexpected claims related to past projects could materially impact financial performance.

Cultural integration is another area of focus. Saunders International has stated that Aqua Metro’s entire workforce, including key management, will remain in place to ensure continuity. Aqua Metro Chief Executive Officer Manish Pancholi will join Saunders International’s senior leadership as Executive Vice President of Saunders Aqua Metro. Analysts agree that staff retention and maintaining project delivery standards will be essential to achieving the expected earnings per share accretion in FY2026.

What could the acquisition mean for Saunders International’s longer-term valuation and investor appeal?

If integration is successful and Aqua Metro achieves its earn-out targets, Saunders International could significantly enhance its valuation profile by FY2027. Stable, annuity-style revenue streams are often valued at a premium by institutional investors compared to cyclical engineering contracts. The capital-light nature of Aqua Metro’s operations, with capex typically below 1% of revenue, could further boost Saunders International’s free cash flow, improving its balance sheet flexibility and positioning it for additional acquisitions.

Institutional sentiment is gradually shifting towards viewing Saunders International as a diversified infrastructure services group rather than just an engineering contractor. Analysts believe that the Aqua Metro acquisition could be the first in a series of strategic moves aimed at capturing market share in critical infrastructure segments, particularly water security and energy transition.
