South African industrial and mining energy spend exceeds R300 billion annually across electricity, diesel, coal and LPG. The practically gas-switchable subset, diesel generation, mine haulage, industrial process heat within trucking range, and heavy road freight corridors, is estimated at roughly R52 billion per annum, before adding the export helium opportunity (~R6bn attributable).
Market sizing: TAM, SAM, SOM
A top-down structure, cross-checked bottom-up from customer conversion economics, frames the opportunity. The total addressable market of ~R310 billion is the full energy wallet the Company’s products can theoretically address; the serviceable addressable market of ~R58 billion is the gas-switchable subset within an ~800 km trucking radius plus a realistic helium export share; and the serviceable obtainable market, the sponsor’s FY2031 revenue of R4.6 billion, equals just 7.9% of SAM.
NoteMarket share versus delivery constraint
The binding constraint on FY2031 revenue is not demand, SOM is under 8% of SAM, but the Company’s own drilling success, plant commissioning and logistics build-out. Market risk is therefore predominantly execution risk. The helium SOM implies export contracts of ~289,000 mcf in FY2031, roughly 4.7% of global traded supply, which would make AetherGas a top-eight global supplier in year five; lenders should treat this as an upper-quartile outcome.

Policy is broadly supportive: the Gas Master Plan and IRP revisions position gas as a transition fuel for industry and flexible power, and carbon-tax escalations widen LNG’s cost advantage each budget cycle. Key risks are MPRDA/UPRDA legislative-transition timelines, municipal servitude approvals, and Karoo community engagement, noting that this is conventional gas with no hydraulic fracturing, a distinction that must be communicated clearly.
