- 01Otto sells SM71 stake to Byron, pending shareholder approval.
- 02Proceeds ~$5.9m plus $325k bond refund.
- 03Byron assumes closure costs; Lightning sale planned.
Otto Energy (ASX: OEL) has agreed to sell its 50% working interest in the South Marsh Island 71 (SM71) oil and gas asset to existing operating partner Byron Energy as it continues to reduce its US asset portfolio.
The proposed transaction delivers US$2.5 million at completion, alongside retained production receipts expected to lift Otto’s total cash proceeds to about US$6.0m, excluding a separate bond refund.
Byron will assume the field’s plugging, abandonment, and decommissioning obligations, removing a material future liability from Otto’s balance sheet if the sale completes.
With SM71 representing its main undertaking, Otto needs shareholder approval for the disposal, targeting completion for 18 December.
The company also intends to begin a separate sale process for its Lightning operation interest during November.
Following the SM71 disposal, Otto would retain Lightning, Mosquito Bay West, Oyster Bayou South, and Green Canyon 21, for which it is reviewing alternative options.
Production Rights to Accumulate
Effective from 1 September, the agreement allows Otto to retain proceeds from its SM71 production until 2,928 production hours have accumulated, a threshold it expects to reach in early January 2027.
Otto estimates approximately US$3.5m of net receipts from this reserved production, while contributing a fixed US$115,000 each month towards operating costs during the period.
After deducting about US$180,000 of prepaid insurance costs, the expected transaction value is approximately US$5.9m, with a further US$325,000 due when Byron refunds Otto’s share of a production bond.
Around 1,450 production hours had accrued as at 31 October, with roughly half of expected November and December oil output hedged at fixed prices of US$96.60 and US$94.50 a barrel respectively.
Byron already operates SM71 and holds the other 50% working interest, making it the buyer of Otto’s stake following a broader marketing process.
Decommissioning Risk to Buyer
Byron will take responsibility for historical and future liabilities, backed by a bond of approximately US$2.9m in favour of Otto and the US Bureau of Ocean Energy Management.
Otto had provided US$3.05m for these obligations at 30 June, highlighting the financial significance of transferring the field’s eventual closure responsibilities.
SM71 accounted for about 47.8% of Otto’s net operating revenue in the 2026 financial year and represented 25.8% of its proved reserves and 30.2% of its proved and probable reserves.
The board considers the proposed sale preferable to retaining an ageing field whose output now comes almost entirely from one producing completion.
The company plans to apply proceeds to working capital, managing its remaining assets, and potential future capital returns, while a separate proposed A$20m shareholder distribution and 100-for-one share consolidation face a vote on 13 November.
