Highlights

  • LGI Limited delivered H1 FY25 statutory revenue growth of 6.7% to $16.9 million and Underlying EBITDA growth of 3.0% to $7.26 million, with the period benefiting from additional generation capacity from the Canberra power station new generators and increased grid connection output — demonstrating the operating leverage inherent in LGI's low-variable-cost landfill gas generation model.
  • LGI shares trade at A$3.40 as at March 31, 2026 — up 14.09% over the past year — against a EODHD/Others consensus Strong Buy rating and target price of A$4.54, representing implied upside of approximately 33.5% from current levels and making LGI the highest consensus-rated stock among the three utilities covered in this analysis.
  • Near-term earnings are being transitionally impacted by three identifiable and quantifiable cost increases: a 20.6% step-up in depreciation and amortisation from the Canberra power station upgrade (now a fully depreciating asset), a 160.4% increase in net interest expense from partial debt-funding of recent capex, and a decline in NPAT of 22.5% to $2.4 million — all reflecting investment in growth rather than deterioration of the underlying business model.

LGI Limited (ASX:LGI) occupies a distinctive and strategically significant niche within Australia's energy sector. Unlike conventional power generators, LGI's business is built around the capture and conversion of landfill gas — methane produced by the anaerobic decomposition of organic waste in municipal and commercial landfills — into electricity for supply to the national grid. This landfill gas-to-energy model positions LGI at the intersection of two powerful policy tailwinds: the requirement for emissions reduction from waste management (landfill gas is a potent greenhouse gas that, if uncaptured, is released directly into the atmosphere), and the growing demand for renewable energy generation as Australia accelerates its electricity system transition away from coal-fired power.

At A$3.40 as at March 31, 2026 — an increase of 14.09% over the preceding twelve months — LGI is the strongest performer among the three utilities in this analysis, having delivered positive share price appreciation in a period when both AGL and Contact Energy declined. The EODHD/Others consensus Strong Buy rating with a target price of A$4.54 implies a further 33.5% upside from the current level — the highest implied return among the three stocks and a reflection of the consensus view that LGI's niche market position, government-aligned emissions reduction business model, and growth pipeline remain underappreciated at current prices.

The company's H1 FY25 results, covering the six months ended December 31, 2024 (under LGI's June financial year), provide the most recent detailed financial disclosure available and offer a case study in how a growth-oriented infrastructure business navigates the transitional period between completing a capital investment and beginning to fully harvest its financial returns.

The Landfill Gas-to-Energy Business Model: Why LGI Occupies a Defensible Niche

Understanding LGI's financial performance requires first understanding the distinctive economics of landfill gas-to-energy generation. Landfill gas is produced continuously by the biological decomposition of organic waste material — a process that occurs regardless of energy market conditions and cannot be switched on or off like conventional generation. This means that LGI's primary 'fuel' supply is effectively free and available on a continuous basis, once the gas extraction infrastructure is installed and the landfill is operating.

The business model therefore exhibits very low variable operating costs relative to most electricity generation technologies. Once a landfill gas capture system and generator are installed, the marginal cost of producing an additional megawatt-hour of electricity is minimal — the primary costs are maintenance, labour, and transmission/grid connection charges rather than fuel. This low variable cost structure creates a high degree of operating leverage: once fixed costs (including D&A on capital investment) are covered, incremental revenue flows through to earnings at a high margin rate, which explains LGI's Underlying EBITDA margin of approximately 46.7% in H1 FY25.

The regulatory and commercial arrangements underpinning LGI's revenue are also relatively stable compared to merchant electricity generators. Many landfill gas generation projects benefit from long-term contracts with landfill operators for gas supply rights, and the electricity generated qualifies for Large-scale Generation Certificates (LGCs) under Australia's Renewable Energy Target legislation. LGCs represent a government-mandated subsidy mechanism that provides a revenue stream additional to the wholesale electricity price, improving project economics and providing a degree of revenue support that is not available to non-eligible generators.

This combination — continuous fuel supply, low variable costs, LGC revenue eligibility, and stable landfill operator relationships — gives LGI a business model that is structurally different from the merchant power generation businesses operated by AGL or Contact Energy. The primary risk variables are therefore not electricity price volatility (LGCs provide a floor revenue contribution) or fuel cost (gas is captured rather than purchased) but rather the development pipeline — the ability to identify, permit, and commission new landfill gas capture projects at sufficient scale to drive revenue and EBITDA growth.

H1 FY25 Results: Parsing the Revenue Growth and Earnings Pressure

LGI's H1 FY25 results, covering the six months ended December 31, 2024, present a picture of genuine top-line growth alongside transitional earnings pressure from identifiable and quantifiable cost increases — a financial profile that requires careful disaggregation to understand correctly. Statutory revenue and other income (excluding interest income) grew 6.7% to $16.9 million, driven by additional generation from the Canberra power station's new generators and increased grid connection and energy output in November 2024. Net Revenue grew 5.4% to $15.6 million, reflecting similar drivers after netting certain costs against revenue.

Underlying EBITDA grew 3.0% to $7.26 million — a more modest growth rate than revenue, which reflects the pattern of fixed costs not scaling proportionally with revenue growth during a period of business expansion. The Underlying EBITDA margin of 46.7% compared to 47.7% in the prior corresponding period, a compression of 106 basis points, is consistent with the expansion period dynamics rather than any indication of structural margin pressure. In a higher-revenue steady state, the EBITDA margin would be expected to recover as fixed costs are absorbed across a larger revenue base.

The most significant financial developments in the period are at the line items below EBITDA, where three specific and connected cost increases drove the majority of the earnings impact. Depreciation and amortisation increased 20.6% from $2.52 million to $3.05 million — a substantial percentage increase that the company specifically attributed to the Canberra power station upgrade now being included as a fully depreciating asset. This is a textbook example of the D&A step-up that accompanies the commissioning of new capital: once a major asset moves from construction-in-progress (where it is not yet depreciating) to operating asset status (where depreciation begins), the D&A charge increases immediately while the full revenue benefit may take some months to fully materialise as operations ramp.

Net interest expense increased by 160.4% from $381,000 to $992,000 — the largest percentage increase of any line item in the income statement and the one requiring the most careful contextualisation. The increase is directly attributable to partial debt-funding of recent capital expenditure. LGI, like most infrastructure businesses, funds its capital programme through a combination of equity and debt, and as additional capex is drawn down and deployed, the associated interest cost grows. The 160.4% increase in interest expense reflects the substantial capital investment that has been made in the Canberra expansion, which is now generating revenue, and in other growth projects that are progressing through the development pipeline.

The combined effect of higher D&A (investment-related) and higher interest (debt-funded capex) drove Statutory and Underlying Net Profit After Tax down 22.5% from $3.10 million to $2.40 million. Diluted earnings per share of 2.7 cents compared to 3.5 cents in the prior period, a decline of 22.9%. While these headline NPAT and EPS declines are clearly negative on their face, they are the direct and anticipated consequence of LGI's capital investment programme — not evidence of operating underperformance or structural deterioration in the underlying business model.

The Canberra Power Station: The Primary FY25 Growth Driver

The Canberra power station project is the most consequential single capital project in LGI's recent history and the primary driver of the H1 FY25 results' revenue growth. The project involved the installation of new generators at an existing Canberra landfill site, expanding the site's electricity generation capacity and increasing the volume of landfill gas captured and converted to power. Additional grid connection capability was also commissioned, enabling LGI to export more electricity to the national grid from the expanded Canberra facility.

The specific mention of 'increased grid connection and energy output in November 2024' as a revenue driver indicates that the Canberra expansion was not fully operational for the entire six-month period — the November 2024 commissioning date means the facility contributed approximately two months of full-capacity operations to the H1 FY25 result rather than six. This partial-period contribution is important context for investors modelling the full-year run rate: the Canberra contribution to revenue and EBITDA in H2 FY25 (January–June 2025) and beyond would reflect a full six-month period of operation, providing a natural tailwind to reported results in subsequent periods without requiring any new capital investment.

The step-up in D&A from the Canberra upgrade is also now fully reflected in the run rate. The D&A increase of approximately $521,000 in the half — from the Canberra asset joining the depreciating asset base — is a recurring cost that will be present in all future periods. However, the revenue from the expanded Canberra facility also continues into all future periods, and the net contribution of the project to earnings will improve as the revenue-generating asset operates for longer proportions of each reporting period.

Capital Structure and the Interest Expense Trajectory

The 160.4% increase in net interest expense — from $381,000 to $992,000 in H1 FY25 — deserves specific attention because it is the clearest indicator of the debt trajectory LGI has adopted to fund its capital programme. For a company of LGI's size and earnings profile, the absolute interest expense figures are still modest in the context of total revenue of $16.9 million and EBITDA of $7.26 million. At $992,000 for the half, annualised interest expense of approximately $2 million represents approximately 13.8% of annualised EBITDA — a leverage level that remains manageable and is well within the range typically considered appropriate for infrastructure businesses with stable contracted cash flows.

The trajectory of interest expense in future periods will depend on the pace of LGI's capital programme — specifically, how quickly new projects are identified, approved, and construction-funded. Each new landfill gas project added to the portfolio requires upfront capital for extraction infrastructure, gas processing equipment, generators, and grid connection, typically partially funded by debt. As the portfolio grows, both revenue (from new generation capacity) and interest expense (from the associated debt) will increase. The key metric investors should track is the EBITDA-to-interest coverage ratio, which should remain comfortably positive if the company's project economics are sound.

The unchanged dividend of 1.2 cents per share — identical to the H1 FY24 dividend — reflects LGI's decision to maintain shareholder returns at current levels while prioritising capital allocation toward growth investments. For a growth-oriented small-cap infrastructure company, maintaining a flat dividend during a period of significant capex and transitional earnings pressure is a reasonable policy choice that prioritises reinvestment over distribution. As the capital programme matures and cash generation stabilises, dividend growth is the natural outcome — a dynamic that underpins some element of the analyst target price premium implied by the A$4.54 consensus target.

The Growth Pipeline and the Strategic Rationale for the Strong Buy Rating

The EODHD/Others consensus Strong Buy rating with a target price of A$4.54 — implying 33.5% upside from the current A$3.40 level — reflects analysts' view that LGI's addressable market, project pipeline, and earnings growth trajectory are underappreciated in the current share price. The core of the bull case for LGI is relatively straightforward: Australia has hundreds of active landfill sites that produce landfill gas, many of which either lack electricity generation infrastructure or have suboptimal capture and conversion systems. LGI's specialised expertise in landfill gas-to-energy project development, construction, and operation gives it a competitive advantage in identifying, developing, and operating these projects at scale.

Each new project added to the portfolio adds revenue and EBITDA at relatively high margins once the initial capital is deployed and the facility is operating. The cumulative effect of a growing portfolio of low-variable-cost landfill gas generation sites is a compounding revenue and earnings base that does not depend on commodity price cycles, government subsidies above the LGC regime already in place, or technological breakthroughs. The growth is driven by organic project development and the physical expansion of an already-established and operating business model.

LGI's 14.09% share price appreciation over the past twelve months — the strongest performance among the three utilities in this analysis — reflects the beginning of market recognition of this growth narrative. The gap between the current A$3.40 share price and the A$4.54 consensus target suggests analysts believe this recognition process has further to run as the company's project pipeline delivers new capacity additions and the Canberra contribution scales to its full run rate in subsequent reporting periods.

Conclusion

LGI Limited is a structurally distinctive business in Australia's energy sector — a specialist landfill gas-to-energy company with low variable costs, government-supported revenue streams through LGCs, and a growing portfolio of projects that convert an environmental liability (landfill methane) into clean electricity. The H1 FY25 results reflect the transitional earnings impact of the Canberra expansion — with D&A and interest expense rising ahead of the full revenue ramp — but the underlying revenue growth of 6.7% and EBITDA growth of 3.0% confirm that the base business is expanding. At A$3.40, with a consensus Strong Buy target of A$4.54 and 14.09% positive share price momentum over the past year, LGI presents the most constructively positioned stock of the three utilities in this analysis on current analyst consensus metrics.
