QUARTERLY ACTIVITIES REPORT

For the quarter ended 30 September 2025

88 Energy Limited (ASX: 88E, AIM: 88E, OTC: EEENF) (88 Energy, 88E or the Company) provides the following summary of activities for the quarter ended 30 September 2025

Alaskan Portfolio Highlights

Project Phoenix, Alaska (75% WI)

Farm-Out Activity and Work Program Progressing:

Ø Joint venture partner Burgundy Xploration LLC (Burgundy) advanced it's funding strategy and met all 2025 JV lease rental obligations.

Ø Planning for the Franklin Bluffs-1H horizontal well and extended flow test continued,  targeting mid-CY2026 spud.

Ø The well will target the SMD-B reservoir, part of the Campanian sequence, the best-developed topset sandstone in the SMD series at Project Phoenix.

Ø Adjacent operator, Pantheon Resources confirmed a 565ft hydrocarbon column in the SMD-B reservoir at Dubhe-1, exceeding pre-drill expectations by 26%[1]. Additional hydrocarbon zones encountered in the SMD-C and two Slope Fan horizons highlighted the broader prospectivity.

Ø Licensing of the Great Bear 3D dataset enhanced planning and provided improved subsurface understanding across Project Leonis and Project Phoenix.

Project Leonis, Alaska (100% WI)

Planning Progressed for Tiri-1 Exploration Well:

Ø Planning and permitting advanced for the proposed Tiri-1 exploration well, to test the Canning and USB Prospects, with additional deeper reservoir potential under review.

Ø All key vendors submitted operational proposals, contributing to a robust well Authority for Expenditure (AFE).   

Ø 88 Energy's 100% working interest positions the Company favourably to secure a material carry through the active farm-out process, with third party evaluation ongoing for a well in Q1'27.

Ø Permitting and operations planning remain in an advanced state, ready to resume in mid-CY26.

Namibian Portfolio Highlights

PEL93 Namibia (20% WI)

Licence Extension and Pre-Drill De-Risking Underway:

Ø The Namibian Ministry of Mines and Energy granted a 12-month extension to the PEL 93 First Renewal Exploration Period, now expiring in October 2026.

Ø A high-resolution gravity survey is planned for Q1 CY26, covering the southern area of PEL 93 where multiple structural leads have been identified.

Ø Regional activity continues to build, with nearby operator ReconAfrica drilling its Kavango West-1X exploration well that spud in July 2025. The well, which shares similar geological characteristics with Lead 9 in southern PEL 93.

Project Longhorn

Strategic Divestment Completed

Ø Divestment of 88E's 65% working interest in Project Longhorn completed, effective 1 July 2025, for US$3.25 million before adjustments.

Ø The divestment followed the Company's decision not to participate in the operator's multi-well program, avoiding exposure to estimated US$2 million per well development costs.   

Corporate Activity

Ø Cash balance of A$8.3 million as at 30 September 2025.

Ø Small Holding Share Sale Facility closed on 1 August 2025. Sales of the parcels, (individually valued under A$500) remained in progress at quarter-end, with the proceeds to be distributed once all shares are sold, expected by year-end 2025.

Ø Mr. Philip Byrne retired as Non-Executive Chairman of 88 Energy Limited, effective 22 August 2025, succeeded by Ms. Joanne Williams.

Alaskan Portfolio Detail

Project Phoenix (~75% WI)

Joint Venture Partner Farm-Out Overview

Agreed terms with Burgundy to fully fund up to US$39 million (approx. A$60 million) of Project Phoenix's total gross future work program costs in exchange for up to an additional 50% Working Interest (WI) in Project Phoenix. Transaction provides the requisite funding pathway to advance Project Phoenix towards a final development decision via a two-phase farm-in arrangement:

Ø Phase 1: Burgundy to fund US$29 million (approx. A$45 million) for CY25/26 work program, including drilling of a horizontal well and production testing scheduled for mid-CY26 (88E fully carried; 88 Energy WI post Phase 1 farmout 35%).

Ø Phase 2: Upon Phase 1 Success; Burgundy to fund up to US$10 million (approx. A$15 million) for an additional well or other CAPEX program (88E carry up to US$7.5 million, based on current 75% WI; 88 Energy WI post Phase 2 farmout to 25%). 

Franklin Bluffs-1H Horizontal Well and Extended Production Test

88 Energy continued to work with Burgundy to advance planning and permitting for the Franklin Bluffs-1H horizontal test well and flowback operation (FB-1H) scheduled for mid-CY26. FB-1H will target the SMD-B reservoir, one of the most promising zones identified at the Hickory-1 discovery well.  

Burgundy appointed Fairweather LLC, a specialist Alaskan service provider, to manage permitting, well design, operations logistics, stimulation program and production test through the second half of 2025.

Completion of the Farm-out Participation Agreement remains subject to relevant government and other approvals, as well as customary conditions precent for farm-out transactions, and Burgundy securing Phase 1 funding by 31 December 2025, unless extended by mutual consent.

Geological Context of the SMD-B Reservoir

The SMD-B reservoir, part of the Campanian sequence, is the best-developed topset sandstone in the SMD series at Project Phoenix. The Hickory-1 well intersected 52 feet of net pay, with porosity ranging from 5-11%, while Icewine-1 intersected 69 ft net pay and showed higher porosity values ranging from to 8-14%, indicating improved reservoir quality in the Icewine-1 location.

Flow testing of the SMD-B at Hickory-1 in Q1 CY24 confirmed oil mobility with samples of 38.5-39.5 API gravity oil and a low gas-oil ratio. These results demonstrate reservoir deliverability and provide confidence that horizontal stimulation can enhance productivity. For full details, refer to the ASX announcement dated 15 April 2024.

Pantheon Resources' Dubhe-1 appraisal well represents a significant validation of the commercial potential of the SMD reservoirs. The well confirmed a 565 ft hydrocarbon column in the SMD-B topset horizon, exceeding pre-drill expectations by 26%, and also encountered hydrocarbon-bearing zones in the SMD-C and two Slope Fan intervals.

These results provide a compelling production analogue for 88 Energy's Franklin Bluffs-1H horizontal well. Together with the Hickory-1 flow test, Dubhe-1 confirms reservoir quality, hydrocarbon mobility and thickness across the SMD-B interval, supporting future commercial development potential for Project Phoenix.

Project Leonis (100% WI)

Tiri-1 Exploration Well Update

Planning and permitting for the Tiri-1 exploration well continued during the quarter, with all major vendors submitting operational proposals, resulting in a robust AFE and Major permitting C-Plan milestone approved by the State of Alaska.

Multiple parties continued technical due diligence on Project Leonis during the quarter. The proposed Tiri-1 well is currently positioned to intersect the Canning and USB reservoirs and to test deeper exploration potential. The final well location will be confirmed in consultation with prospective farm-in parties, with the well anticipated to be drilled in Q1'27.  Preparations for the drilling of an exploration well at Leonis are advanced and will resume mid-2026.

Namibia PEL 93 (20% WI)

PEL 93 Forward Work Program

The Joint Venture is preparing to commence the airborne gravity survey in Q1 2026, focusing on the southern portion of the license area in the heart of the Owambo Basin. This follows identification of Lead 9, a very large anticlinal structure, during the H2 2024 2D seismic program. Lead 9 is analogous to the structure currently being drilled by ReconAfrica's Kavango West 1X well. Both structures exhibit large, robust structural closures incorporating shallow clastic reservoirs, the deeper Otavi carbonate reservoir (seen in Naingopo-1) and the deeper source rocks. According to the Operator of PEL 93, Monitor, the regional structural model suggests the presence of a series of similar features extending across the southern Owambo Basin. Early gravity and radiometric data suggest even larger structural leads may be present in the southeast of the block.

Regional Catalysts Building: ReconAfrica's Kavango West 1X Well

88 Energy notes the ongoing drilling of the nearby Kavango West 1X exploration well by ReconAfrica (TSXV: RECO) in the adjacent Damara Fold Belt. This well is targeting a large fold structure approximately 20 km long and 5 km wide, anticipated to penetrate a thick Otavi carbonate reservoir with mature source rocks within the same closure.

ReconAfrica commenced drilling of its Kavango West 1X exploration well in July 2025, on a structure which has striking similarities to Lead 9 located in the southern area of PEL 93. Drilling is proceeding on schedule, and the final casing string has been set just above the targeted Otavi reservoir. ReconAfrica expect to reach TD of ~3,800m in 2nd half of November prior to commencing an extensive logging program with results around 2025 year-end.

This regional activity highlights growing industry interest in the broader Owambo Basin.

Project Longhorn

On 18 August 2025, the Company announced it executed a binding Securities Purchase Agreement (SPA) with Lonestar I, LLC (Lonestar), Operator of Project Longhorn, for the sale of its 65% non-operated working interest in the producing oil and gas assets located in the Permian Basin, Texas, USA (Project Longhorn), held through subsidiary Longhorn Energy Investments LLC (88E - Longhorn) with an effective date of 1 July 2025 for total consideration of US$3.25 million before customary working capital and completion adjustments. The Company elected not to participate in the proposed multi-well drill program by the Operator and relieved exposure to a development program of US$2 million per well.

Full for details refer to the ASX announcement on 18 August 2025.

Corporate

At 30 September 2025, the Company's cash balance was A$8.3 million (US$5.4 million). The attached ASX Appendix 5B sets out the Company's cash flow for the quarter.

Material cash flows for the period include:

·      Exploration and Evaluation Expenditure: A$0.6 million (June 2025 quarter A$0.7 million) related to Leonis Tiri-1 permitting and planning and PEL 93 work program costs.
