Mike Harding 
Chairman 
A MESSAGE FROM OUR CHAIRMAN 
2024 saw the continuation of the strong cash 
generation and dividend declarations that 
have become a consistent theme for Horizon. 
For the 4th consecutive year, the Company 
has been able to return at least AUD 3.0 cents 
per share to shareholders, with the final 
FY24 dividend announced of AUD 1.5 cents 
per share, which followed the earlier interim 
dividend paid of AUD 1.5 cents per share.
It is with mixed emotions that I recently announced 
my intended retirement from the Horizon Board at 
the upcoming AGM. Horizon is a Company I have 
grown very fond of, having taken on the role at a time 
when the Company was deeply indebted and facing 
strategic headwinds which had eroded shareholder 
value.
Over my 6 years as Chairman, we significantly reduced 
the level of gearing and streamlined the business to 
become a lean, highly cash generative oil and gas 
company paying  substantial distributions which 
now amount to over AUD 170 million. Having recently 
completed the acquisition of a third producing asset, 
and with a wellestablished management team with 
Richard at the helm, I feel that now is the right time 
for me to retire from the Board. I am delighted that 
Bruce Clement, having been a non-executive director 
for 4 years, will succeed me as Chairman as he brings 
a wealth of knowledge and experience to the role.
In consideration of my impending retirement, the 
Company’s transition into a domestic gas producer, 
and with a well-established management team, the 
Board considers that now is an appropriate time for a 
Board refresh.
With my planned retirement from the Board at the 
conclusion of the 2024 AGM, Bruce Clement has 
agreed to assume the role of Chair from the conclusion 
of the AGM. With nearly 4 years of experience on the 
Horizon Board, and with over 40 years’ oil and gas 
experience including leading ASX listed oil and gas 
companies, Beach Energy Limited, AWE Limited and 
Roc Oil Limited, Bruce is well qualified to lead Horizon 
into the future.
Following a thorough search focused on identifying 
a technically strong Board member to replace me as 
a nonexecutive director, the Board has identified ex-
Transfield CEO/MD, Dr Peter Goode. Dr Goode brings 
over 40 years’ experience in engineering, and oilfield 
services, and is currently Chairman and co-founder 
of the leading US Onshore completions provider, 
GR Energy Services. It is intended that Dr Goode be 
appointed to the Board effective 1 September 2024, 
and in accordance with ASX listing rules he will stand 
for election by shareholders at the 2024 AGM.
As also recently announced, non-executive director 
Sandra Birkensleigh plans to retire from the Board in 
2025 after over 8 years of service. I would like to thank 
Sandra for her time and contribution to the Board, 
particularly as audit committee Chair. Whilst Sandra 
will seek re-election at the upcoming AGM, she will 
assist in finding a replacement for her during her next 
term.
Finally, I would like to say thank you for having me as 
Chairman and I wish all those associated with Horizon 
all the best for the future.

A MESSAGE FROM OUR CEO 
 
 
Building on the success we’ve had in recent 
years, Financial Year 2024 was a pivotal year 
for the Company following the successful 
completion of the Mereenie acquisition. In 
adding a third production asset to the portfolio, 
we have diversified the production base, 
materially added to the Group’s reserves, 
and added an asset which can provide a 
production base beyond the expiry of our 
existing assets. The subsequent signing of a 
long-term strategic gas supply agreement 
with the NT government so soon after 
completing the acquisition was a tremendous 
outcome and underscores the strategic merit 
of the acquisition and Mereenie’s importance 
to domestic gas supply.
Whilst the Mereenie acquisition was the headline 
announcement during the year, our legacy assets 
of Block 22/12 and Maari continued to provide the 
reliable, high margin financial horsepower to which 
we have grown accustomed. Once again, the Block 
22/12 joint venture was able to successfully execute 
an infill drilling campaign which restored production 
back above the field long term average of 10,000 bopd 
(gross). The ability of the joint venture to efficiently 
convert contingent resources to developed reserves 
continues to unlock value for Horizon shareholders, 
and planning is underway for a potential CY25 infill 
drilling campaign. The infill wells executed at the 
WZ12-8E field during the year have increased the 
production base from this field providing further 
confidence that WZ12-8E production will extend out 
further to towards the end of the decade. This led 
to a material reserves upgrade at Block 22/12. Maari 
also made a material financial contribution during the 
year with an 18% increase in production combined 
with strong premiums achieved on Maari sales adding 
meaningful additional free cashflow. The prospect of 
licence extension at Maari out to the end of the decade 
and potentially beyond continues to look promising, 
with a key milestone achieved during the year with 
critical infrastructure recertified for a further 5 years. 
In addition, a licence extension application is nearing 
completion with regulatory lodgement expected 
shortly. If granted, an extension to the licence would 
add material value to the Company and provide a 
continued pathway for distributions.
Financially, the Company remains in a position of 
strength with net cash of over US$26 million, following 
both the Mereenie acquisition and the dividend 
payments totalling approximately US$37 million. 
Cash generation from our assets remains exceptional 
allowing the continuation of the Company’s strategy 
to prioritise distributions to shareholders. In addition 
to the AUD 1.5 cent per share interim dividend paid in 
April 2024, we have approved a further AUD 1.5 cent 
per share final dividend to be paid in October 2024. 
These distributions combined represent over a 15% 
dividend yield for the year. With approximately AUD 
170 million returned to shareholders over the past 
3 to 4 years and with a further AUD 24 million to be 
returned over the coming months, we have continued 
to sustain a top tier dividend yield which has become 
a hallmark of Horizon’s success and stood us apart 
from many of our peers. Given our continued robust 
cashflow generation, our desire is for distributions to 
continue to be a recurring feature in the years ahead.
On the ESG front, safety continued to remain a priority 
at all our assets, with the Group Total Reportable 
Injury Frequency Rate and Lost Time Injury Frequency 
Rate both well below the NOPSEMA industry average. 
This is a testament to the quality and diligence of the 
operators of our assets – CNOOC, OMV and Central 
Petroleum.

Richard Beament 
Chief Executive Officer 
Specifically on climate change, we were pleased to 
see material progress being made during the year at 
our Flinders Biochar Project through our investment 
in Re-Vi (formerly known as Nobrac).
A key milestone was the production of the first 
biochar during the year, with certification of the 
Carbon Removal Credits underway. We also see our 
investment into domestic gas as an integral part 
of supporting the energy transition, with Mereenie 
signing a strategic gas sales agreement with rare 
earther miner, Arafura Rare Earth’s Limited. Gas from 
Mereenie will allow Arafura to process critical rare 
earth minerals which are essential for the production 
of magnets used for motors in wind turbines and 
EVs. The Federal Government support to Arafura 
demonstrates the strategic importance of their 
Nolans Project which will initially rely on gas being 
supplied from the Mereenie field.
Regarding Mike’s recently announced retirement and 
the upcoming Board changes, I would like to extend 
our gratitude, on behalf of the Board and the entire 
Horizon team, for his exceptional contributions and 
support over the past six years. Throughout this time, 
Mike collaborated with the Board and shareholders 
to navigate numerous challenges, ultimately guiding 
the company to realign its strategy. Today, thanks 
to his leadership, Horizon stands out as a leading 
player in the junior energy sector. I also look forward 
to welcoming Peter Goode to the Board and want to 
extend my gratitude to Sandra Birkensleigh for her 8 
years of invaluable service to the Company.
Over the year, our team has put in an enormous effort 
to accomplish our strategic goals. I consider myself 
very lucky to have the support of such a talented 
team of professionals. I thank each of them for their 
dedication and hard work, and congratulate them 
for the results we’ve been able to achieve.
Looking to the future, we remain steadfast in our 
strategy:
• We aim to continue to maximise free cashflow 
from our current high quality assets;
• We are focussed on making further distributions to 
shareholders; and
• We will continue to invest in organic production 
growth initiatives in Block 22/12, Maari and 
Mereenie, whilst keeping an eye out for exceptional 
new business opportunities – our focus is on 
bringing into production our pipeline of contingent 
and prospective resources.
Despite the ongoing challenges faced by our 
business and sector, our capable team have the 
skills and expertise to navigate the obstacles and 
continue to create value for shareholders.

 2024 HIGHLIGHTS
• Horizon booked net 2P gas Reserves of 32 PJ (5.5 MMboe) following the acquisition of a 25% interest in the 
Mereenie producing oil and gas field with an effective date of 1 April 2023. The acquisition is expected to 
meaningfully increase net operating cash flow over the next 5+ years and provide a production base beyond 
the expiry of our existing assets.
• Horizon net Proved + Probable (2P) Reserves doubled from 4.9 MMboe (all crude) at 30 June 2023 to 9.9 
MMboe (44% crude and condensate) at 30 June 2024 as a consequence of the Mereenie acquisition and 
transfers from Contingent Resources to Reserves offset in part by production.
• A very strong year of production including a material contribution from the new Mereenie project with 
Horizon’s total net economic interest share of production of 1.9 MMboe compared with 1.8 MMboe last year. 
China and New Zealand contributed a total of 1.4 MMbbl of oil production while Mereenie contributed 2.7 PJ 
sales gas (0.5 MMboe) for the 15 month period from the1 April 2023 effective date.
• Horizon net 2P crude and condensate Reserves declined by 0.5 MMbbl from 4.9 to 4.4 MMbbl with production 
of 1.4 MMbbl offset in particular by transfers from Contingent Resources to Reserves in China (+0.6 MMbbl) 
and the addition of 0.3 MMbbl associated with the Mereenie acquisition. The China contribution is a 
continuation of the Beibu joint venture strategy of actively working to bring new projects into production 
including four new wells drill in 2024.
• 2C Contingent Resources increased from 6.9 MMboe to 13.3 MMboe primarily due to 45.6 PJ (7.8 MMboe) of 
gas associated with the Stairway and Pacoota reservoirs in the Mereenie asset. China Contingent Resources 
also remain strong at 2.6 MMbbl with up to eleven possible future projects, mostly infill wells.

Notes
1	
All estimates are prepared in accordance with the 
Society of Petroleum Engineers (SPE) Petroleum 
Resources Management System (PRMS) revised 2018. 
2	
Relevant terms used in this statement, capitalised 
or otherwise, have the same meaning given to those 
terms in the SPE PRMS. 
3	
Reserves are those quantities of petroleum 
anticipated to be commercially recoverable by 
application of development projects to known 
accumulations from a given date forward under 
defined conditions.
4	
Contingent Resources are those quantities of 
petroleum estimated, as of a given date, to be 
potentially recoverable from known accumulations 
by application of development projects, but which 
are not currently considered to be commercially 
recoverable owing to one or more contingencies.
5	
Prospective Resources are those quantities 
of petroleum estimated, as of a given date, to 
be potentially recoverable from undiscovered 
accumulations by application of future development 
projects. See also above Cautionary Statement.
6	
Contingent and Prospective Resource estimates 
quoted for China have assumed China National 
Offshore Oil Corporation (‘CNOOC’) participation at 
51%. CNOOC is entitled to participate at up to a 51% 
equity level in any commercial development within 
Block 22/12. Prospective Resources also only include 
Horizon’s on block share.
7	
Liquids are equal to the total of oil, condensate and 
natural gas liquids where 1 barrel of condensate or 
natural gas liquids equals 1 barrel of oil. Gas reserves 
have been converted to oil equivalent using 5.816PJ 
equals one million barrels of oil equivalent.
8	
Raw Gas is natural gas as it is produced from the 
reservoir which may include varying amounts of 
heavier hydrocarbons which liquefy at atmospheric 
conditions, water vapor and other non-hydrocarbon 
gases such as hydrogen sulphide, carbon dioxide, 
nitrogen or helium.
9	
Sales Gas represents volumes that are likely to 
be present a saleable product. Sales Gas are 
reported assuming average values for fuel, flare and 
shrinkage considering the variable reservoir fluid 
properties of each constituent field on an energy 
basis the customary unit is PJ. PJ means petajoules 
and is equal to 1015 joules.
10	 For Reserves and Contingent Resources, depending 
on the asset, either deterministic estimates 
or probabilistic estimates have been used. 
For Prospective Resources, all estimates are 
probabilistic estimates. 
11	
Reported estimates of petroleum Reserves, 
Contingent Resources and Prospective Resources 
have been aggregated by arithmetic summation 
by category. 1P Reserves reported beyond the field, 
property or project level aggregated by arithmetic 
summation may be a very conservative estimate due 
to the portfolio effects of arithmetic summation.
12	 Estimates are reported according to Horizon Oil’s 
net economic interest, this being Horizon Oil’s net 
working interest adjusted for entitlements (Economic 
Interest adjustment) under production-sharing 
contracts and risked-service contracts; and are 
reported net of royalties and lease fuel up to the 
reference point. Reference points for Horizon’s 
petroleum Reserves and Contingent Resources 
and production are defined points where normal 
operations cease, and petroleum products are 
measured under defined conditions prior to custody 
transfer. For China, Horizon’s net economic interest 
ranges from 24.32% to 26.95%. For New Zealand and 
Australia, Horizon’s net economic interest is equal to 
Horizon’s net working interest of 26.00% and 25.00% 
respectively. 
13	 Horizon Oil employs a Reserves Management 
System to ensure the veracity of data used in the 
estimation process. This process includes review 
by senior staff where data is endorsed for inclusion 
in the estimating process. Estimates are reviewed 
annually, at a minimum, with interim reviews as 
required, to respond to any material changes. 
Horizon Oil undertakes semi-regular external reviews 
to complement its own internal process.
14	 The estimates of petroleum Reserves and 
Resources contained in this statement are based

Block 22/12, Beibu Gulf, Offshore China 
A successful four well infill well drilling campaign was largely 
completed during the fourth quarter of the financial year, ahead 
of schedule and under budget, which contributed incremental 
production rates of 2,300 bopd gross (620 bopd net). The drilling 
program restored production back above the long-term field 
average with Block 22/12 production on 30 June 2024 of 10,360 
bopd gross (2,792 bopd net). These rated do not include the 
contribution from the last 12-8E infill well that came online on 13 
July and flowed at approximately 400 bopd gross (Horizon net 
108 bopd) following cleanup. The four well program is forecast 
to recover an incremental 1.3 mmbbl gross (Horizon net 0.35 
mmbbl) to the end of the contract period.
The Joint Venture has also matured a significant water handling 
capacity upgrade project which is expected to be online from 
early 2026. Recovery from this project was previously carried as 
contingent resources but has been reclassified as reserves in 
Horizon’s 30 June 2024 reserves report. The project is forecast to 
recover an incremental 1.2 mmbbl gross (Horizon net 0.3 mmbbl) 
to the end of the contract period. Horizon will pay the Operator 
an additional Opex processing tariff for its proportionate share 
of additional water handling once the project is online.
The Block 22/12 Joint Venture continues to evaluate and mature 
further infill drilling targets with a view to executing a drilling 
program during calendar year 2025, subject to rig availability 
and joint venture approvals. 
 1 Cost recovery oil entitlement is a right under the Block 22/12 Petroleum Contract to additional oil production to compensate Horizon for historical exploration 
expenditure incurred in the Block. The current entitlement is associated with historical WZ12-8E exploration costs.
During the financial year, the Group’s working interest share 
of production from the Beibu Gulf fields was 945,236 barrels 
of oil, with production declining as expected back towards 
the long term field average following the successful WZ12-
8E development drilling during the prior year. Average gross 
production over the financial year was over 9,600 bopd, of 
which the Group’s share was 2,590 bopd. 
Crude oil sales for the financial year were 911,280 barrels at 
an average price of US$84/bbl exclusive of executed hedging. 
Oil sales and revenue benefited from an incremental cost 
recovery oil entitlement resulting in an additional ~US$3.9 
million of revenue recorded for the financial year. 
Cash operating costs for the year were US$19.40/bbl 
(produced), excluding the costs of well workovers mentioned 
below.
A three well workover campaign was completed in the second 
half of the financial year comprising activities to restore 
production from two currently inactive wells, and preparatory 
work on a third inactive well to enable side-tracking during the 
subsequent Q4 drilling program.

Towards the end of the second quarter, the Maari JV 
commenced a workover on the shut-in MR6A well with the 
aim of reinstating oil production from the Maari Mangahewa 
and to exploit a previously unproduced Matapo Sandstone 
behind pipe opportunity.  Unexpected workover unit repairs 
in December resulted in the temporary suspension of the 
workover.  With those repairs completed during the financial 
year, and following the successful MR8A and MR10 ESP 
changeouts (see below), the workover re-commenced 
subsequent to year end.
Production was impacted during the fourth quarter by ESP 
failures in the MR8A and MR10 production wells, noting that 
both pumps materially exceeded their expected operational 
lifespans.  Following completion of the workover unit repairs, 
the pumps were replaced and both wells were successfully 
brought back online.
The Operator received the FPSO class extension certificate 
from the certifying authority ABS which allows the facility 
to continue to operate for a further five years through to 
April 2028, subject to meeting ongoing continuous survey 
requirements.  This, together with the continued favourable 
production trends at Maari provides the joint venture with the 
confidence to pursue life extension beyond the current 2027 
permit expiry, including the preparation of licence extension 
documentation which is planned to be lodged with the 
regulator later this calendar year.
During the financial year, the Group’s working interest share 
of production from the Maari and Manaia fields increased 
18% on the prior year to 463,309 barrels of oil owing largely 
to the successful restoration of production from the shut-
in Manaia-1 well. Average gross production over the year 
was 4,868 bopd, of which the Group’s share was 1,266 bopd. 
Crude oil sales were 373,358 barrels, generating revenue of 
US$34.5 million at an average realised price of US$92.40/bbl 
exclusive of executed hedging.  Maari crude oil continued to 
attract significant premiums to dated Brent which enhanced 
cashflow generation from the asset during the period.  Cash 
operating costs for the year were US$24.70/bbl (produced). 
Crude oil inventory at 30 June 2024 was 116,501 bbls with a 
lifting of over 127,000 bbls (net to HZN) deferred to July 2024 
which generated revenue in excess of US$10 million.
The Maari Joint Venture completed the conversion of the 
MR2a well to a permanent water injector in September 2023. 
Following the workover, MR2a is now providing pressure and 
displacement support to the producing wells.

led to varied gas production, influenced by decreased buyer 
nominations.  In April 2024, a Gas Supply Agreement (GSA) was 
announced with Power and Water Company (PWC) to supply 
gas to the NT on an as-available basis throughout 2024, 
substantially offsetting the impact of the NGP shutdown.
Subsequent to the end of the year, and in response to an 
expression of interest to buyers for gas supply during the 
2025-2030 period, the Mereenie JV entered into a long-term 
strategic gas sales agreement (GSA) with the Northern Territory 
Government (NTG).  The new GSA covers the firm supply of 
gas for the 6 year period from 1 January 2025 through until 
31 December 2030 to underpin the domestic supply of gas to 
the Northern Territory.  Together with an amended existing 
gas supply agreement with Arafura Rare Earths Limited (ARU), 
the Mereenie joint venture has now substantially contracted 
the forecast Mereenie Proved Developed Producing (PDP) gas 
production on a firm take or pay basis until the end of 2030 
at current market prices, subject to the ARU GSA becoming 
unconditional.  These gas sales agreements reduce the 
market dependency on the Northern Gas Pipeline (NGP) with 
the NTG GSA also including contingent offtake arrangements 
for firm gas nominations in 2025 if the NGP is offline.  The NTG 
GSA also supports the drilling of two proposed infill wells at 
Mereenie with contingent offtake arrangements for firm gas 
nominations following successful drilling.
The JV continues to focus on additional 2024/25 work program 
activities, including helium recovery initiatives and further 
infill drilling opportunities with the proposed two well infill 
drilling program being endorsed by the JV subsequent to the 
end of the financial year. The infill well program is targeting 
incremental gas production at Mereenie with drilling activities 
expected to commence around the middle of FY25. 
On 11 June 2024, the Company advised that its acquisition of a 
25% non-operated interest in the producing Mereenie oil and 
gas field completed.  The effective date of the transaction was 
1 April 2023, with revenues earned and costs incurred during 
the period from the effective date to completion adjusted 
against the initial cash consideration of A$42.5 million 
(~US$27.6 million).  Horizon’s share of production volumes 
during the approximate 14 month period between effective 
date and completion were 
2.6 PJs of gas and 0.05 mmbbls of oil.  Funding for the initial 
cash consideration was from a new A$42.5 million senior debt 
facility which was executed with Macquarie Bank.  Financial 
close and drawdown of the facility occurred on 11 June 2024 
to enable completion of the acquisition.  Subsequent to the 
period end, the Company paid the first contingent milestone 
payment for the acquisition amounting to A$5 million (~US$3.3 
million) following certain commercial milestones being 
achieved.
The acquisition was executed together with Echelon Resources 
Limited (ASX: ECH) (formerly known as New Zealand Oil & Gas 
Limited), an incumbent Mereenie joint venture partner, who 
acquired a further 25% participating interest in OL4 and OL5 
from Macquarie on identical terms.  Central Petroleum remains 
as operator of the Mereenie joint venture and manages the 
gas sales function on behalf of Horizon, ECH and Cue under a 
joint marketing agreement. 
Gross production for the 3 weeks since completion of the 
transaction was 0.4PJ (Horizon net 25%: 0.1PJ) of gas and 
5,740 bbls (Horizon net 25%: 1,435 bbls) of oil.  Cash receipts 
from Mereenie over recent months have been impacted by 
the shutdown of the Northern Gas Pipeline (NGP) which has

Review of operations 
Principal activities 
During the financial year, the principal activities of the Group continued to be directed towards petroleum production, 
development and exploration. 
A detailed review of the operations of the Group during the financial year is set out in the Activities Review on pages 
11 to 14 of this annual financial report. 
Group Financial Performance 
Consolidated Statement of Profit or Loss and Other Comprehensive Income 
2024 Profit Drivers 
The Group reported a statutory profit after tax of US$25.9 million for the financial year (2023: US$43.9 million) with non-cash 
items impacting on the financial year result including US$30.1 million (2023: US$38.5 million) in amortisation of production 
phase assets and US$1.2 million (2023: US$1.4 million) of non-cash expense related to the value of performance rights and 
share appreciation rights granted to Horizon employees.   
EBITDAX was US$71.5 million (2023: US$103.5 million) and EBIT was US$40.3 million (2023: US$59.8 million).  Cashflows from 
operating activities of US$64.2 million (2023: US$72.0 million) enabled the Group to return ~US$37 million to shareholders 
whilst also meeting its capital expenditure commitments and repaying a further US$7.9 million in debt during the financial 
year.  
EBITDAX and EBIT are financial measures which are not prescribed by Australian Accounting Standards and represent the 
profit under Australian Accounting Standards adjusted for interest expense, taxation expense, depreciation, amortisation, 
HORIZON OIL ANNUAL REPORT 2024
16

and exploration expenditure (including non-cash impairments).  The directors consider EBITDAX and EBIT to be useful 
measures of performance as they are widely used by the oil and gas industry.  EBITDAX and EBIT information has not been 
audited.  However, they have been extracted from the audited annual financial reports for the financial years ended 30 June 
2024 and 30 June 2023. 
Basic earnings per share for the financial year was 1.60 US cents based on a weighted average number of fully and partly 
paid ordinary shares on issue of 1,617,370,026 shares. 
Sales and Production 
The Group’s producing assets performed well despite the overall decline in Horizon’s net working interest share of production 
to 1,426,687 boe for the financial year (2023: 1,915,886 bbls).  Production from Maari was particularly strong, increasing 18% 
from the prior period following the restoration of production from the MN1 well and the conversion of MR2a to a permanent 
water injector.  As anticipated, production from Block 22/12 declined naturally during the period following the successful 
WZ12-8E infill drilling during the prior year, with production levels restored back above 10,000 bopd towards the end of the 
year following the four well drilling campaign completed in July 2024.  The drilling campaign is forecast to recover an 
incremental 1.3 million barrels gross (0.35 million barrels, HZN net working interest) to the end of the contract period.  
Sales volumes for the financial year declined in line with production to 1,301,155 boe (2023: 1,774,437 bbls) with 119,564 bbls 
of crude oil inventory on hand as at 30 June 2024 following the deferral of a Maari lifting from June to July 2024.  Sales 
revenue for the financial year was US$111.5 million (2023: US$152.1 million), with a net realised oil price of US$85.7/bbl (2023: 
US$85.71/bbl), inclusive of hedge settlements.  The deferred Maari lifting occurred in July 2024, generating further revenue 
of over US$10 million.  
Production and sales volumes above exclude Horizon’s economic entitlement to Mereenie pre-completion production of 2.6 
PJs (~0.5 mmboe) of gas and 0.05 mmbbls of oil back to the transaction effective date of 1 April 2023.  For accounting 
purposes, the pre-completion cashflows are set off against the acquisition price in the balance sheet and not booked 
through the income statement during the year.  On an economic interest basis, Horizon’s total share of production for the 
financial year inclusive of Mereenie pre-completion production was approximately 1.9 mmboe, broadly consistent with the 
prior year. 
Operating costs for the period were US$62.9 million (2023: US$81.2 million).  The reduced costs were mainly the result of lower 
production levels at Block 22/12 reducing amortisation charges and the deferred Maari lifting which significantly increased 
the crude oil inventory held on the balance sheet at the end of the financial year.  The lower production volumes also resulted 
in reduced special oil levies from Block 22/12.  
General and Administrative Expenses 
General and administrative expenses reduced by US$1.0 million during the financial year to US$2.8 million (2023: US$3.8 
million).  The reduction was driven by a reduction in headcount coupled with a reduction in non-cash share-based payment 
expenses.  General and administrative expenses comprised net employee benefits expense of US$1.7 million (including non-
cash share-based payment expense of US$1.2 million), corporate office expense of US$0.8 million, and depreciation of 
US$0.2 million. 
Insurance Expense 
Insurance expense of US$2.1 million (2023: US$2.0 million) was in line with the prior financial period. 
Exploration and Development Expenses 
Exploration and development expenses were US$0.8 million (2023: US$4.6 million) and was focused on appraisal and 
exploration opportunities in and around Block 22/12 in China and the evaluation of inorganic growth opportunities including 
the Mereenie acquisition. 
Finance Costs/Income 
The Group’s net borrowing costs of US$1.1 million were US$1.7 million lower during the period following the full repayment of 
the Group’s Cash Advance Facility in July 2023 coupled with a higher average balance of cash held in interest bearing 
accounts/term deposit.  
Income and Royalty Tax 
The net income and royalty tax expense of US$13.3 million (2023: US$13.1 million) incurred during the financial year included 
a current tax expense of US$12.4 million, a deferred income tax benefit of US$2.1 million and a royalty related tax expense of 
US$3.0 million.  The net income tax expense was driven by cash taxes of US$9.8 million in China and US$2.6 million in New 
Zealand.  Royalty tax expense of US$2.9 million reflected cash and deferred royalty tax associated with the Maari/Manaia 
field.

Consolidated Statement of Financial Position 
At 30 June 2024, total assets were US$205.3 million (2023: US$183.5 million) and total liabilities were US$122.0 million (2023: 
US$87.7 million), resulting in net assets of US$83.2 million (2023: net assets of US$95.8 million).  The initial purchase 
consideration for the Mereenie acquisition was fully debt funded, accordingly the acquisition did not have a material impact 
on the net asset position of the Group as at 30 June 2024.  
At 30 June 2024, the Group reported a net cash position of US$26.2 million.  Net cash of US$26.2 million comprised of cash 
and cash equivalents held of US$52.6 million (2023: US$43.6 million) offset by borrowings of US$26.4 million (2023: US$7.9 
million).  At financial year end, borrowings consisted of US$26.4 million principal outstanding on the Group’s debt Facility.   
Consolidated Statement of Cash Flows 
2024 Cash Drivers 
Net cash generated from operating activities for the financial year was US$64.2 million (2023: US$72.0 million) which when 
coupled with the disciplined spending and significantly lower capital costs incurred during the period, resulted in the 
continued build in cash reserves notwithstanding the significant shareholder distributions and debt repayments made during 
the period.  The build in cash reserves was further aided by the full debt funding of the initial purchase consideration for the 
Mereenie Acquisition.  
Corporate 
Group liquidity 
At 30 June 2024, the Group’s net cash position was US$26.2 million (30 June 2023: US$35.7 million) following ~US$37 million 
in dividends paid to shareholders during the financial year and the US$26.4 draw down on a new 5 year debt facility used to 
fund the Mereenie Acquisition.  Net cash comprises cash and cash equivalent assets held of US$52.6 million (30 June 2023: 
US$43.6 million) offset by the nominal value of borrowings drawn down of US$26.4 million (30 June 2023: US$7.9 million) on 
the Group’s debt facility.  Details of the Group’s debt facilities are set out in Note 19. 
Dividends 
The Board has declared a final dividend of AUD 1.5 cents per Ordinary share totalling approximately AUD 24.3 million.  This 
dividend was declared as a Conduit Foreign Income (CFI) unfranked dividend and will be paid on 25 October 2024.  During the 
financial year, the Board also declared an interim dividend of AUD 1.5 cents per Ordinary share totalling approximately AUD 
24.3 million.  This dividend was declared as a Conduit Foreign Income (CFI) unfranked dividend and was paid on 26 April 2024. 
Oil Price Hedging 
The Company maintains leverage to the oil price with a minimal hedge position.  At the date of this report, hedges were in 
place for 77,500 bbls of oil covering the period to November 2024, with a weighted average fixed price of US$82.64/bbl.

Group business strategies and prospects for future financial years 
The Company’s exploration, development and production activities are focused in China and Australasia.  The robust cash 
flows from the Company’s interests in Block 22/12, offshore China; Maari/Manaia fields, offshore New Zealand and Mereenie, 
onshore Australia, will be applied to fund the Company’s future capital and growth program, and to repay debt, with surplus 
funds returned to shareholders.  The growth program is focussed on enhancing shareholder value by bringing into production 
the Company’s substantial inventory of contingent and prospective resources in fields in China, New Zealand and Australia, 
whilst keeping an eye on potential other value accretive growth opportunities. 
The Company has a targeted and selective exploration and development strategy with specific focus on plays providing 
material scale and upside in and around existing permits with ready access to development infrastructure.  The reserves 
and contingent resources in the company’s inventory provide shareholders with exposure to commodity price upside and 
potential production growth opportunities. 
The achievement of these strategic objectives may be affected by macro-economic and other risks including, but not limited 
to, global growth, volatile commodity prices, exchange rates, climate change, access to financing and political risks.  The 
speculative nature of petroleum exploration and development will also impact the Company’s ability to achieve these 
objectives; key risks of which include production and development risk, exploration and drilling risks, joint operations risk, 
and geological risk surrounding resources and reserves. 
The Group has various risk management policies and procedures in place to enable the identification, assessment and 
mitigation of risks that may arise.  Whilst the Group can mitigate some of the risks described above, many are beyond the 
control of the Group.  For further information in relation to the Company’s risk management framework, refer to the Corporate 
Governance Statement. 
Outlook 
In the near term, continued strong operating cashflow generation is forecast with the Group’s overall production enhanced 
and diversified with the addition of the Mereenie asset.  Production levels and cashflows from each field are forecast to be 
impacted by natural reservoir decline in the near-term before further infill drilling and other production enhancing initiatives 
are progressed.  These cashflows are expected to enable continued returns to shareholders and funding for further 
production growth opportunities. 
The Group’s short-term focus is on: 
– Continued optimisation of production performance from the Block 22/12, Maari/Manaia and Mereenie fields;  
– Maturing further infill drilling opportunities, particularly at Block 22/12 and Mereenie;  
– Pursuing life extension at Maari; and 
– Continued evaluation of organic and inorganic opportunities.  
Matters subsequent to the end of the financial year 
Other than the matters noted above and disclosed in the review of operations, there has not been any matter or circumstance 
which has arisen since 30 June 2024 that has significantly affected, or may significantly affect: 
[1] - 
the Group’s operations in future financial years; or 
[2] - 
the results of those operations in future financial years; or 
[3] - 
the Group’s state of affairs in future financial years. 
Environmental regulation 
The Group is subject to significant environmental regulation in respect of exploration, development and production activities 
in all countries in which it operates – China, New Zealand and Australia.  Horizon Oil Limited is committed to undertaking all 
of its exploration, development and production activities in an environmentally responsible manner. 
The Directors believe the Group has adequate systems in place for managing its environmental requirements and is not 
aware of any breach of those environmental requirements as they apply to the Group. 
Reporting currency 
The Company’s and the Group’s functional and reporting currency is United States dollars.  All references in this annual 
financial report to “$” or “dollars” are references to United States dollars, unless otherwise stated.

Corporate Governance 
The Company and the Board are committed to achieving and demonstrating the highest standards of corporate governance.  
The Board continues to review the Company’s governance framework and practices to ensure they meet the interests of 
shareholders.  The Corporate Governance Statement was approved by the Board on 28 August 2024.   
The Company’s Corporate Governance Statement for the year ended 30 June 2024 may be accessed from the Company’s 
website at www.horizonoil.com.au.  A description of the Company’s main corporate governance practices is set out in the 
Corporate Governance Statement.  All these practices, unless otherwise stated, were in place for the full financial year and 
comply with the ASX Corporate Governance Council’s revised Corporate Governance Principles and Recommendations 4th 
edition, released in 2019. 
Sustainability Reporting 
Sustainability continues to be an important focus for Horizon with progress made during the current financial year on 
Horizon’s Environmental Social and Governance (ESG) Action Plan.  Summarised below for each of Horizon’s ESG priority areas 
is an update on the progress made for the year ended 30 June 2024.  
The Company’s Sustainability Report for the year ended 30 June 2024 may be accessed from the Company’s website at 
www.horizonoil.com.au.  
The Australian Federal Government is proposing amendments to the Corporation Act.  The Government’s objective is to 
improve transparency and comparability of information available to investors regarding Australian entities exposure to 
climate-related financial risks, opportunities, and their plans and strategies in response to these exposures.  If the 
amendments are enacted, Australian entities will be required to adopt new standards developed by the Australian 
Accounting Standards Board (AASB).  The standards will be largely based on the International Sustainability Standards 
Board’s (ISSB) International Financial Reporting Standards (IFRS) S1 and S2.  The disclosure requirements will be gradually 
phased in, depending on entity’s consolidated gross assets, revenue and number of employees.  We are closely monitoring 
the evolving disclosure requirements and will assess the need for changes in ESG reporting expected to be effective for the 
financial year commencing 1 July 2026 to ensure ongoing compliance and reporting accuracy.  
The ESG metrics discussed below, exclude Mereenie data, given that the completion of Horizon’s asset acquisition was close 
to the end of FY24 (11 June 2024).  Going forward, Mereenie ESG performance metrics will be included with Horizon’s other 
operations, based on Horizon’s percentage equity position.  Horizon’s materiality review will be reconducted in FY25, with 
the Mereenie asset most like having some bearing on the company’s ESG focus areas.  
Health, safety & environment (HSE) 
Both Block 22/12 and Maari have continued their strong safety performance, despite significant drilling, workover and 
production activities.  As at the financial year ended 30 June 2024, Horizon achieved a Total Recordable Injury Frequency 
Rate (TRIFR) of 3.30, and a Lost Time Injury Frequency Rate (LTIFR) of zero, both less than the National Offshore Energy 
Regulator (NOPSEMA) industry averages in Australia.  There were zero fatalities and zero material environmental incidents 
for FY24.  Our Operators continue to run safety awareness campaigns with the objective of continuous improvement. 
The Directors believe the Group has adequate systems in place for managing its environmental requirements and is not 
aware of any breach of those environmental requirements as they apply to the Group. 
Governance  
Governance continues to be a core focus for the Group.  The Board continues to have oversight of ESG strategy and 
performance, including climate change, with support from the Sustainability Steering Committee.  During the period Horizon 
conducted its annual assessments on its value and supply chain for risks and incidences of modern slavery.  The Modern 
Slavery Statement, for FY2023, was published in line with the requirements of the Australian Modern Slavery Act 2018.  The 
work on 2024 Modern Slavery Statement is currently underway to be submitted in December 2024.  This statement may be 
accessed from the Company’s website at www.horizonoil.com.au.  During the year, Horizon has conducted further checks 
around Cyber Security with improvement actions being implemented.   
Climate change 
Climate change continues to be of importance to the Group, and the recent investment into domestic gas is an important 
step in supporting the energy transition.  The Mereenie oil and gas field provides gas for both domestic consumption and for 
the mining and processing of minerals critical to the energy transition.  The Group’s investment in Re-Vi (formerly Nobrac) 
continues to progress, with its biochar project achieving first production with certification of carbon removal credits 
underway.  Horizon continues to support our Operators in emission reduction initiatives. Scope 1 absolute emissions for FY24 
HORIZON OIL ANNUAL REPORT 2024
25

is approximately 22% lower than FY23, with most of the reduction attributable to production decline.  FY24 has seen the 
implementation of some emission reduction initiatives.  Refer to the Group’s Sustainability Report for more details.   
Horizon continues to acquire and surrender carbon credits in New Zealand Units (NZUs) under the NZ Emissions Trading 
Scheme (ETS) to cover 100% of the Group’s share of Maari Scope 1 emissions.  Through participation in the NZ ETS, the 
Company is supporting New Zealand in achieving its stated commitment to Net Zero GHG emissions by 2050 in alignment 
with the Paris Agreement. 
People – Employees & Community  
The Company continues to focus on its employees and provides workplace flexibility and initiatives to enhance productivity 
and staff morale.  Horizon continues to work with our Operators and partners to identify and participate in relevant and 
meaningful community-based projects.

[2] - Executive Remuneration Framework 
 
[2.1] - 
How does Horizon determine remuneration outcomes?  
The objective of the Group’s remuneration framework is to provide reward for performance that is competitive and 
appropriate for the results delivered.  The Board, through its Remuneration and Nomination Committee, continues to review 
KMP remuneration arrangements to ensure they align with the Group’s strategic objectives.  The remuneration framework 
for executives is based on the following principles for guiding the Group’s decisions regarding executive remuneration. 
– Good reward governance principles: 
– competitiveness and reasonableness; 
– performance linkage / alignment of executive compensation; 
– transparency; and 
– capital management. 
HORIZON OIL ANNUAL REPORT 2024
27

 
– Alignment to shareholders’ interests: 
– focuses on sustained growth in shareholder value; and 
– attracts and retains high calibre executives capable of managing the Group’s diverse international operations. 
 
– Alignment to program participants’ interests: 
– rewards capability and experience; 
– reflects competitive reward for contribution to growth in shareholder wealth; 
– provides a clear structure for earning rewards; and 
– provides recognition for contribution. 
 
[2.2] - Remuneration policy and link to performance 
The remuneration framework is designed to recognise performance during the financial year (Short-Term Incentives (STIs)) 
and maximise shareholder value (Long-Term Incentives (LTIs)).  Executive remuneration is comprised of fixed and variable 
(“at risk”) remuneration consisting of STIs and LTIs.  LTI’s were issued to the below executives during the financial period 
following their appointments to drive long term value creation.  LTI’s are not planned to be awarded annually.  The graph 
below sets out the mix of total annual fixed remuneration and the maximum variable remuneration in the form of STI’s.  
Annual incentives have been established to drive performance without encouraging undue risk taking.  The mix of Total fixed 
remuneration and Short-term incentives for the financial year is shown in the table below with percentages rounded to the 
nearest whole number.

[2.3] -  Elements of remuneration  
FIXED REMUNERATION (FR)  
What is Fixed 
Remuneration? 
Fixed Remuneration comprises ‘Total Fixed Remuneration’ (TFR), together with non-monetary benefits.  TFR 
is base salary plus superannuation.  Non-monetary benefits include car parking, insurances and other 
expenses inclusive of fringe benefits tax.  Executive remuneration (which is set and paid in Australian 
Dollars (A$)) and other terms of employment are reviewed annually by the Remuneration and Nomination 
Committee having regard to relevant comparative information.   
Link to strategy and 
performance 
Competitive TFR is paid to ensure that the Group can attract and retain suitable executives to deliver the 
strategic goals.  Fixed Remuneration is reviewed annually by the Remuneration and Nomination Committee 
considering market data, scope of the Executive’s role, expected skill, experience and qualification and 
individual performance. 
 
 
Performance-based 
HORIZON OIL ANNUAL REPORT 2024

SHORT-TERM INCENTIVE (STI)  
Objective 
The STI provides all Executives with an opportunity to earn an annual incentive which is paid in a combination 
of cash and deferred equity in the first quarter of the new financial year.  The deferred equity element is 50% 
of the total STI awarded with the residual paid in cash.  The STI award is determined by the Board following 
the end of the financial year having regard to Group performance over the financial year.  
How is the STI linked to 
performance? 
The STI is designed to motivate and reward Executives for contributing to the delivery of annual business 
performance.  Key Performance Indicators (KPIs) are determined each financial year and approved by the 
Board.  The Company’s performance against these KPIs is reviewed annually.  
How is performance 
measured for the STI? 
Awards are made annually with performance measured over the twelve months to 30 June and are aligned 
to the attainment of the Company’s Board approved KPIs for the relevant year.  Awards under the plan are 
determined and paid in a combination of cash and deferred equity in the first quarter of the new financial 
year.  The deferred equity element is subject to the specific terms of the executive’s employment 
agreement.  Actual performance against financial, non-financial and individual measures is assessed at the 
end of the financial year.  In assessing the achievement of measures, the Remuneration and Nomination 
Committee may exercise its discretion to adjust outcomes for significant factors outside the control of 
management that contribute positively or negatively to results.  
STI opportunity 
Up to 75% of the Chief Executive Officer’s TFR, up to 60% of the Chief Operating Officer’s TFR and up to 50% 
of the Chief Financial Officer’s TFR.  A proportion of each executive’s STI award will be granted in the form of 
deferred equity rights with the residual STI paid in cash.  The proportions of the STI award paid in cash and 
received in deferred equity rights will depend on the executive’s position in the Company and ranges 
between 25% - 50% of the total STI awarded.  Deferring a proportion of the STI outcome into rights to Shares 
creates further alignment between the interests of shareholders and extends the focus beyond the short 
term.   
How is STI deferred 
equity granted?   
Any deferred component of STI awarded in relation to a financial year (Performance Year) will be delivered in 
the form of rights to acquire fully paid ordinary shares in the Company ('Shares') for nil consideration ('Deferred 
STI Rights'). 
How is the number of 
Deferred STI Rights 
determined? 
The number of Deferred STI Rights granted in relation to any Performance Year will be determined by dividing 
the cash amount of the STI to be deferred by the volume weighted average price ('VWAP') of Shares for the final 
10 trading days of the Performance Year (usually 10 trading days up to 30 June). 
What are the 
performance 
conditions on the 
Deferred STI Rights? 
Deferred STI Rights are designed to reward past performance and encourage retention.  Once granted, 
ordinarily, no further performance conditions will attach to Deferred STI Rights other than the employee 
remaining in the Company's employment at the time of vesting.  
Distribution and capital 
reorganisation 
The number of Deferred STI Rights will be adjusted in the event of reorganisation of capital and a participant 
will be entitled to receive a distribution equivalent payment in the form of additional shares to the value of 
dividends the participant would have received during the deferral period.  Deferred STI rights will not attract 
dividend and voting rights. 
When and how do 
Deferred STI Rights 
vest? 
Deferred STI Rights will vest (subject to Board discretion and satisfaction of any applicable condition) 100% 
after 12 months.  Vesting periods will generally commence on 1 July of the year in which the Deferred STI Rights 
are granted.  The Board may satisfy any Deferred STI Rights that vest by procuring that Shares are purchased 
on market and transferred or issue new Shares in the Company. 
Clawback and Board 
discretion in relation to 
STI Rights 
The Board retains a broad discretion to: 
•
allow for accelerated vesting in special circumstances (e.g., death and incapacity);  
•
determine that some or all unvested Deferred STI Rights will lapse if any situation arises that, in the 
Board’s view should impact the assessment of performance.  Such situations may include material 
misrepresentations and material misstatements in the Company's accounts; 
•
allow for accelerated vesting in certain circumstances e.g. change of control event; and 
•
determine that any Deferred STI Rights that vest are settled in cash not Shares (subject to any ASX 
Listing Rule or Corporations Act requirements).

LTI PLAN (PERFORMANCE RIGHTS) 
How is the LTI linked 
to performance? 
The LTI Plan for Performance Rights applies to LTI’s issued on and after 1 July 2022.  The objective of the 
Performance Rights granted pursuant to the LTIP is to create a stronger link between eligible employees’ 
performance and reward, increasing shareholder value via the proposed LTIP.  The LTI Plan forms part of the 
Company’s performance-based remuneration system and provides “at risk” incentives based on longer term 
Company performance. 
Offer to participate in 
the Plan and 
consideration 
The Board may from time to time make offers (each a Plan Offer) to an ‘Eligible Person’ (being, any person 
who is an employee (including in full-time or permanent part-time employment) or a director of, or a person 
who provides services to, the Company or its related bodies corporate, or any other person so designated by 
the Board) to participate in the Plan and receive a right to be allocated a fully paid ordinary share in the 
Company (Share), subject to the rules of the Plan (Share Right).  
 
A Plan Offer may be subject to such restrictions and conditions as the Board determines in its absolute 
discretion (including, in relation to the applicable expiry date, exercise period and performance criteria). 
 
Unless otherwise stated in the Plan Offer, a participant in the Plan (Participant) is not required to pay for a 
grant of Share Rights or the allocation of Shares under a Plan Offer. 
 
Participation in the Plan does not give the Participant a legal or beneficial interest in a Share prior to its 
allocation to the Participant, nor any entitlement to a Share, otherwise than in accordance with the Plan Offer 
and the rules of the Plan. 
Grant of Share Rights 
As soon as reasonably practicable following receipt by the Company of an Eligible Person’s acceptance of a 
Plan Offer, the Company will, provided that the relevant person continues to be an Eligible Person, issue to 
the person the number of Share Rights the subject of the accepted Plan Offer. 
 
Share Rights will not give a Participant any right to dividends or give a Participant a right to vote.  However, 
Shares issued, transferred or allocated (as applicable) upon a relevant Participant exercising their vested 
Share Rights will convey the same rights to dividends and voting as Shares in the same class. 
Term of Share rights 
Subject to the terms of the Plan (including in relation to circumstances relating to cessation of employment), 
the ‘Last Exercise Date‘ (being, the latest date on which a Share Right may be exercised if the Share Right 
vests) and ‘Plan Acceptable Date‘ (being, the latest date on which the Company must receive a completed 
plan acceptance form from a relevant Participant), are determined by the Board in respect of each grant of 
Share Rights.  The Share Rights granted have an expiry date no longer than 5 years. 
Performance criteria 
applicable to Share 
Rights 
The Board has discretion to prescribe the conditions which must be satisfied or waived before a particular 
grant of Share Rights vests and becomes exercisable by the relevant Participant.  
 
A Share Right may only be exercised if it is a vested Share Right and it has not lapsed in accordance with the 
terms of the Plan. 
Exercise price on 
vested Share Rights 
The Board may determine whether any exercise price must be paid by the participant on the exercise of vested 
Share Rights.   
Allocation of Shares 
If a relevant Participant opts to exercise vested Share Rights, the Company will allocate to the Participant the 
number of Shares to which the Participant is entitled by either (or a combination of) issuing new Shares to the 
Participant or procuring the transfer of Shares acquired on market to the Participant. 
Cessation of 
Employment 
In the case of any “Uncontrollable Events” (including death, permanent disablement, retirement, 
retrenchment, or such other circumstances which result in the Participant leaving the employment of the 
Company or any of its related bodies corporate and which the Board determines is an uncontrollable event) 
resulting in a Participant’s cessation of employment, the Board may determine that any unvested Share 
Rights either lapse or become vested Share Rights. 
 
If the Participant ceases employment other than because of an Uncontrollable Event, all of the Participant‘s 
unvested Share Rights will automatically lapse. 
Lapse of Share Rights 
Share Rights may lapse in other circumstances, including where the applicable performance criteria are not 
wholly satisfied by the time specified in the Plan Offer (unless otherwise specified in the Plan Offer), or where 
the Participant commits any act of fraud, defalcation or gross misconduct in relation to the Company’s, or 
any of its related bodies corporate’s affairs. 
Change of Control 
If a Change of Control Event occurs, or the Board determines in its absolute discretion that a Change of Control 
Event is likely to occur, subject to the performance criteria applicable to unvested Share Rights, the Board 
will determine the appropriate treatment regarding any unvested Share Rights, which may include waiving 
the relevant performance criteria, replacing unvested Share Rights with rights to Shares in a new controlling 
entity, or causing the unvested Share Rights to lapse. 
Re-organisation of 
capital, rights issue, 
dividend or other 
such event 
Upon any re-organisation of the issued ordinary capital of the Company, the number of Share Rights, or the 
number of Shares allocated on the exercise of the Share Rights, or both will be reconstructed or adjusted to 
the extent necessary to comply with, and in accordance with, the ASX Listing Rules applying to a re-
organisation of capital at the time of the reorganisation (as their application in the circumstances is affected 
by any waiver granted by ASX).

Key Terms of the 
Share Rights issued 
onwards from 1 July 
2022 
The tables below set out the material terms of Share Rights issued under the New LTIP.   
Share Price Hurdle 
Each tranche of Share Rights vests independently of each other tranche of Share Rights. 
 
The Share Price Hurdles are subject to the following adjustments: 
– the relevant Share Price Hurdle will be increased by 10% on each anniversary of the Start Date, commencing 
on the third anniversary of the Start Date; 
– the relevant Share Price Hurdle will be decreased by an amount determined by the Board (in its absolute 
discretion) to account for any dividends or return of capital; and 
– the relevant Share Price Hurdle will be increased or decreased (as applicable) by an amount determined by 
the Board (in its absolute discretion) to account for any share consolidation or other re-organisation of 
capital of the Company. 
Performance Criteria 
Each tranche of Share Rights will vest on the first and any relevant subsequent date following grant date upon 
satisfaction of all of the following conditions:  
 
•
the price per share meets or exceeds the relevant Share Price Hurdle at the close of trade (each, a 
Relevant Gateway Date); 
•
the volume weighted average price of the shares on the ASX for the preceding 1-month period meets or 
exceeds the relevant Share Price Hurdle at close of trading on the date that is one year thereafter each 
Relevant Gateway Date (each, a Relevant Anniversary Date); 
•
Shares traded in the twelve-month period from the Relevant Gateway Date to the Relevant Anniversary 
Date at or above the relevant Share Price Hurdle have a cumulative market value (assessed at the time 
each trade was made) of $25,000,000 or more; and  
•
the recipient remains an employee of the Company on the vesting date.  
 
Accordingly, the Share Rights granted in respect of each Tranche may be tested in relation to more than one 
period (i.e. in respect of successive Relevant Gateway Dates and associated Relevant Anniversary Dates) and, 
subject to the terms of the Plan and the Plan Offer, will vest in their entirety on the earliest Relevant 
Anniversary Date on which all of the vesting conditions noted above are satisfied. 
Share Right Exercise 
Price 
Nil 
Expiry of exercise 
period 
If a Share Right vests, then the Share Right may be exercised at any time up to the date which is the earlier 
of: 
•
three years after the Share Right vested; and 
•
the date on which a Change of Control Event occurs or the date on which the Board makes a 
determination that a Change of Control Event is likely to occur.

LTI PLAN (SARS)  
LTI PLAN (SARS) 
The LTI plan for SARs applied to LTIs awarded prior to 1 July 2022.  It will not apply to the award of LTIs after 
1 July 2022. 
Objective 
The LTI plan aimed to align Executive remuneration with the creation of shareholder value.   
How is the LTI linked 
to performance? 
LTI vesting is linked to absolute Horizon share performance, and Horizon share performance relative to the 
S&P ASX 200 Energy Index.  
Form of LTI grant? 
LTIs are awarded as performance rights, known as share appreciation rights (SARs). 
 
SARs vest over a three-to-five-year period on fulfilment of two performance criteria: (1) Horizon’s Total 
Shareholder Return (TSR) must exceed 10%; and (2) Horizon’s TSR must equal or exceed the S&P ASX 200 
Energy Index (Index), with the level of outperformance determining the proportion of SARs that vest.  
 
The SAR value on vesting is calculated as the difference between the Horizon share price at allocation, and 
the Horizon share price at exercise.  The Company may settle the SAR value in cash or shares or a 
combination, in the Board’s absolute discretion.  
What are the 
performance 
measures applied to 
the LTI?  
The Board considered that the absolute and relative TSR performance hurdles effectively align the interests 
of Executives with Horizon’s shareholders, by motivating Executives to achieve superior outcomes.  TSR is a 
robust and transparent means of measuring shareholder returns. 
 
SARs vest over a three to five-year period on fulfilment of two performance criteria:  
 
(1) Horizon’s Total Shareholder Return (TSR) must exceed 10%; and  
(2)  Horizon’s TSR must equal or exceed the S&P ASX 200 Energy Index, whereby the proportion of SARs that 
vest is calculated as follows: 
 
–
if Horizon’s TSR is equal to the Index, 50% vest; 
–
if the Company’s TSR is 14% or more above the Index, 100% vest; and 
–
if Horizon’s TSR is between the Index and 14% above the Index, a percentage vest based on a linear 
pro-rata calculation. 
 
Performance 14% above the Index equates to a performance level likely to exceed the 75th percentile of 
market returns of companies in the Index (weighted by company size). 
Performance period? 
SARs will first be tested for vesting at 3 years from award; and thereafter re-tested every 6 months until 
5 years from award.  
What was the LTI 
opportunity? 
The former CEO had an LTI opportunity equal to 50% of TFR, and other Executives at that time had an LTI 
opportunity equal to 21.4% of TFR.  The LTI opportunity is prescribed by the Executives’ employment 
contracts.  
 
The number of SARs issued to an Executive in a relevant year is calculated by dividing the monetary value of 
the Executive’s LTI opportunity by the fair value of a SAR at allocation.  The fair value of a SAR is determined 
by an independent expert each year using the Black-Scholes model.  
Treatment of 
incentives on 
cessation of 
employment 
On cessation of an Executive’s employment, the Board may exercise its discretion to: (1) lapse all or some of 
the Executive’s SARs; or (2) determine that some or all of the Executive’s SARs which have not become 
exercisable, become exercisable.  
When do SARs lapse? 
 
SARs will lapse: 
– where the SAR has not vested, 5 years after award or such longer period necessary for the Executive to 
freely deal in Horizon securities in accordance with the Securities Trading Policy; 
– the Board exercises its discretion to lapse the SARs on cessation of employment; 
– the Board exercises its discretion to lapse the SARs for serious misconduct or fraud by an Executive; or 
– the Executive provides a notice to Horizon that they wish the SARs to lapse. 
Effect of take-over or 
change of control of 
Company, death or 
disablement 
In the event of a takeover or change of control event, the Board will either have the discretion or be required 
(if a change of control occurs) to determine a special retesting date for vesting of Executives’ SARs.  
 
For example, the Board will have discretion to determine a special retesting date where a takeover bid is 
made for the Company.  In that case, the special retesting date will be the date determined by the Board.  
Where a statement is lodged with the ASX that a person has become entitled to acquire more than 50% of 
the Company, the Board will be required to determine a special retesting date, and the special retesting date 
will be the day the statement is lodged with the ASX.   
 
The SARs will vest if the performance criteria are fulfilled in relation to that special retesting date.

[4] - Group Performance and Financial Year Remuneration Outcomes 
[4.1] - 
Overview of Horizon performance 
The Board aligns remuneration and performance by using ‘at risk’ remuneration, including STI’s and LTI’s.  Award of STIs is 
dependent on overall company performance and the vesting of LTIs (SARs) occurs on fulfilment of absolute Horizon Total 
Shareholder Return (TSR), and Horizon TSR relative to the S&P/ASX200 Energy Index.  Vesting of Performance Rights are 
based on the performance criteria as outlined in section 2.3.  
Horizon share price performance for the current and previous four financial years is displayed in the chart below.  During the 
2024 Financial Year, the Horizon share price increased 29%, which when combined with the 25% distribution yield (aggregate 
of AUD 3.5 cents per share), results in a TSR of 54% for the financial year or approximately A$120 million dollars of value for 
shareholders.  Horizon’s share price closed at AUD 0.18 per ordinary share on 30 June 2024.

[5] - Non-Executive Director Remuneration
NEDs are paid fees for services on the Board and committees and do not receive any performance-related incentives and no 
retirement benefits are provided other than superannuation contributions.  The Remuneration and Nomination Committee 
reviews fees annually and the Board may also seek advice from external advisers when undertaking the review process.
NED fees are determined within an aggregate Directors’ fee pool limit, which is periodically recommended for approval 
by shareholders.  Shareholders approved the current fee pool limit of A$600,000 at the 2009 Annual General Meeting.  
These fees have not changed in A$ terms for the last ten years.  Note that the remuneration table set out on page 37 
shows remuneration in US$ in line with the Group’s functional currency.
The table below shows the levels for NEDs (exclusive of superannuation) for FY24.

Details of remuneration  
For each grant of Performance Rights and Deferred STI Rights issued to KMP in the current or prior financial years which 
results in an amount being disclosed in the Remuneration Report as a share-based payment to KMP for the financial year, 
the percentage of the grant that vested in the financial year and the percentage that was forfeited because the person did 
not meet the vesting or performance conditions is set out below.   
Performance Rights are expensed over the expected vesting period.  The expected vesting date and expected vesting period 
are determined at the date of grant and may differ from the date the Performance Rights actually vest and become 
exercisable.  Based on the performance conditions being met, all Performance Rights on issue vested and were exercised 
prior to the expected vesting date.  As the vesting was based on market related conditions, the rights continue to be 
expensed over the expected vesting period.  
No Performance Rights and Deferred STI will vest if the performance conditions are not fulfilled, therefore the minimum value 
yet to vest is US$Nil.  The maximum value of the SARs, Performance Rights and Deferred STI yet to vest has been determined 
as the amount of the fair value at the grant date that is yet to be expensed.  The below values have been converted to dollars 
at the exchange rate prevailing on the date of the grant. 
 
 
 
Dividends 
The Board has declared a final dividend of AUD 1.5 cents per Ordinary share totalling approximately AUD 24.3 million.  This 
dividend was declared as a Conduit Foreign Income (CFI) unfranked dividend and will be paid on 25 October 2024.  During the 
financial year, the Board also declared an interim dividend of AUD 1.5 cents per Ordinary share totalling approximately AUD 
24.3 million.  This dividend was declared as a Conduit Foreign Income (CFI) unfranked dividend and was paid on 26 April 2024.

Independent auditor’s report 
To the members of Horizon Oil Limited

The accompanying financial report of Horizon Oil Limited (the Company) and its controlled entities 
(together the Group) is in accordance with the Corporations Act 2001, including: 
(a) 
giving a true and fair view of the Group's financial position as at 30 June 2024 and of its 
financial performance for the year then ended  
(b) 
complying with Australian Accounting Standards and the Corporations Regulations 2001. 
What we have audited 
The financial report comprises: 
• 
the consolidated statement of financial position as at 30 June 2024 
• 
the consolidated statement of profit or loss and other comprehensive income for the year then 
ended 
• 
the consolidated statement of changes in equity for the year then ended 
• 
the consolidated statement of cash flows for the year then ended 
• 
the notes to the consolidated financial statements, including material accounting policy 
information and other explanatory information  
• 
the consolidated entity disclosure statement as at 30 June 2024

Basis for opinion 
We conducted our audit in accordance with Australian Auditing Standards. Our responsibilities under 
those standards are further described in the Auditor’s responsibilities for the audit of the financial 
report section of our report. 
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis 
for our opinion. 
Independence 
We are independent of the Group in accordance with the auditor independence requirements of the 
Corporations Act 2001 and the ethical requirements of the Accounting Professional & Ethical 
Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence 
Standards) (the Code) that are relevant to our audit of the financial report in Australia. We have also 
fulfilled our other ethical responsibilities in accordance with the Code.

Our audit approach
An audit is designed to provide reasonable assurance about whether the financial report is free from 
material misstatement. Misstatements may arise due to fraud or error. They are considered material if 
individually or in aggregate, they could reasonably be expected to influence the economic decisions of 
users taken on the basis of the financial report.
We tailored the scope of our audit to ensure that we performed enough work to be able to give an 
opinion on the financial report as a whole, taking into account the geographic and management 
structure of the Group, its accounting processes and controls and the industry in which it operates.
Audit scope
Key audit matters
•
Our audit focused on where the Group made
subjective judgements; for example, significant
accounting estimates involving assumptions and
inherently uncertain future events.
•
Amongst other relevant topics, we communicated
the following key audit matters to the Audit and
Risk Committee:
−
Restoration provision
−
Acquisition of Mereenie
•
These are further described in the Key audit
matters section of our report.
Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in 
our audit of the financial report for the current period. The key audit matters were addressed in the 
context of our audit of the financial report as a whole, and in forming our opinion thereon, and we do 
not provide a separate opinion on these matters. Further, any commentary on the outcomes of a 
particular audit procedure is made in that context. 
Key audit matter
How our audit addressed the key audit matter
Restoration provision
(Refer to note 20)
The estimation of restoration provisions by the Group 
involves significant judgement in selecting 
methodologies and assumptions, the methodology for 
estimating cost and discount rates used to estimate the 
present value of these cash flows.
The restoration provision was a key audit matter due to 
the significance of the balance and the required 
judgement, effort and subjectivity in performing 
procedures and evaluating the Group’s methodology, 
significant assumptions and estimates.
We performed the following procedures, amongst 
others:
• developed an understanding of how the Group
identified the relevant methods, assumptions and
sources of data that are appropriate for developing
the closure plans and associated cost estimates.
• developed an understanding of the relevant control
activities associated with developing the closure
plans and associated cost estimates.
• assessed the appropriateness of the Group’s
significant assumptions used, including the reliability
and relevance of the Group’s key data used in the
closure plans and associated cost estimates.
• tested the mathematical accuracy of the provision
calculations and assessed whether they were in
accordance with the method.
HORIZON OIL ANNUAL REPORT 2024
45

Key audit matter
How our audit addressed the key audit matter
• assessed the reasonableness of the note disclosures
in the financial statements for the year ended 30
June 2024 in light of the requirements of Australian
Accounting Standards.
Acquisition of Mereenie
(Refer to note 26)
During the year, the Group acquired a 25% interest in 
Mereenie oil and gas fields (“Mereenie”) for a total 
consideration of US$31.96 million.
The acquisition of Mereenie has been accounted for as 
a business combination and involved consideration as 
to the acquisition date, and the recognition and 
measurement of identifiable assets acquired and 
liabilities assumed as at that date.
The acquisition was a key audit matter because it had 
a significant financial impact on the Group.
We performed the following procedures, amongst 
others:
• obtained an understanding of the acquisition by
examining key documents including the
Sale/Purchase Agreement, Completion Statement,
and Debt facility letter.
• evaluated the appropriateness of the accounting
treatment of this acquisition against the requirements
of AASB 3.
• tested the purchase consideration, including
contingent payments and net working capital cash
flows adjustment by agreeing them to supporting
documentation.
• assessed the reasonableness of the note disclosures
in the financial statements for the year ended 30
June 2024 in light of the requirements of Australian
Accounting Standards.
Other information
The directors are responsible for the other information. The other information comprises the 
information included in the annual report for the year ended 30 June 2024, but does not include the 
financial report and our auditor’s report thereon.
Our opinion on the financial report does not cover the other information and accordingly we do not 
express any form of assurance conclusion thereon through our opinion on the financial report. We 
have issued a separate opinion on the remuneration report.
In connection with our audit of the financial report, our responsibility is to read the other information 
and, in doing so, consider whether the other information is materially inconsistent with the financial 
report or our knowledge obtained in the audit, or otherwise appears to be materially misstated.
If, based on the work we have performed on the other information that we obtained prior to the date of 
this auditor’s report, we conclude that there is a material misstatement of this other information, we are 
required to report that fact. We have nothing to report in this regard.

Responsibilities of the directors for the financial report
The directors of the Company are responsible for the preparation of the financial report in accordance 
with Australian Accounting Standards and the Corporations Act 2001, including giving a true and fair 
view and for such internal control as the directors determine is necessary to enable the preparation of 
the financial report that is free from material misstatement, whether due to fraud or error.
In preparing the financial report, the directors are responsible for assessing the ability of the Group to 
continue as a going concern, disclosing, as applicable, matters related to going concern and using the 
going concern basis of accounting unless the directors either intend to liquidate the Group or to cease 
operations, or have no realistic alternative but to do so.
Auditor’s responsibilities for the audit of the financial report
Our objectives are to obtain reasonable assurance about whether the financial report as a whole is 
free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that 
includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that 
an audit conducted in accordance with the Australian Auditing Standards will always detect a material 
misstatement when it exists. Misstatements can arise from fraud or error and are considered material 
if, individually or in the aggregate, they could reasonably be expected to influence the economic 
decisions of users taken on the basis of the financial report.
A further description of our responsibilities for the audit of the financial report is located at the Auditing 
and Assurance Standards Board website at: 
https://www.auasb.gov.au/admin/file/content102/c3/ar1_2020.pdf. This description forms part of our

Notes to the consolidated Financial Statements 
Note 1
Summary of Material Accounting Policies 
A summary of the material accounting policies adopted in the preparation of the financial statements are set out below.  
These policies have been consistently applied, unless otherwise stated.  The financial statements are for the consolidated 
entity consisting of Horizon Oil Limited and its subsidiaries (the ‘Group’).  For the purposes of preparing the financial 
statements, the consolidated entity is a for profit entity. 
The nature of the operations and principal activities for the Group are described in the Directors’ Report. 
A.
Statement of compliance 
These general purpose financial statements have been prepared in accordance with Australian Accounting Standards, other 
authoritative pronouncements of the Australian Accounting Standards Board (‘AASB’), Urgent Issues Group Interpretations 
and the Corporations Act 2001. 
The consolidated financial statements comply with Australian Accounting Standards as issued by the AASB and International 
Financial Reporting Standards (‘IFRS’) as issued by the International Accounting Standards Board (‘IASB’). 
B.
Basis of preparation 
These financial statements are presented in United States dollars and have been prepared under the historical cost 
convention, as modified by the revaluation of financial assets and liabilities (including derivative instruments) at fair value 
through profit or loss, or other comprehensive income where hedge accounting is adopted. 
The Company is of a kind referred to in ASIC Corporations (Rounding in Financial/Directors’ Reports) Instrument 2016/191 and 
accordingly amounts in the financial statements are rounded off to the nearest thousand dollars, unless otherwise indicated. 
The general purpose financial statements for the year ended 30 June 2024 have been prepared on a going concern basis 
which contemplates the realisation of assets and settlement of liabilities in the normal course of business as they become 
due.  At the date of this report, the directors are of the opinion that no asset is likely to be realised for amounts less than the 
amount at which it is recorded in the financial report as at 30 June 2024.  Accordingly, no adjustments have been made to 
the financial report relating to the recoverability and classification of the asset carrying amounts or the amounts and 
classification of liabilities that might be necessary should the Group not continue as a going concern. 
New and amended standards adopted by the Group 
There were no new and revised Australian Accounting Standards and Interpretations issued by the Australian Accounting 
Standards Board (‘AASB’) that were relevant to its operations and effective for the financial year ended 30 June 2024. 
There are no other Australian Accounting Standards that are not yet effective and that are expected to have a material 
impact on the Group in the current or future financial years.   
Critical accounting estimates 
The preparation of financial statements requires the use of certain critical accounting estimates.  It also requires 
management to exercise its judgement in the process of applying the Group’s accounting policies.  The areas involving a 
higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial 
statements are disclosed in Note 2. 
Changes in accounting estimates  
A review of the Group’s accounting estimates has not affected items recognised in the financial statements for the financial 
year ended 30 June 2024, except as disclosed in Note 2. 
C.
Principles of consolidation 
Subsidiaries 
The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of Horizon Oil Limited (the 
'Company’ or 'Parent Entity') as at 30 June 2024 and the results of all subsidiaries for the financial year then ended.  Horizon 
Oil Limited and its subsidiaries together are referred to in these financial statements as ‘the Group’. 
Subsidiaries are those entities (including special purpose entities) over which the Group has control.  Control exists when the 
Company is exposed to, or has the rights to, variable returns from its involvement and has the ability to affect those returns 
through its power over that entity.  There is a general presumption that a majority of voting rights results in control.  The 
HORIZON OIL ANNUAL REPORT 2024
55

existence and effect of potential voting rights that are currently exercisable or convertible are also considered when 
assessing whether the Group controls another entity. 
Subsidiaries are fully consolidated from the date on which control is transferred to the Group.  They are de-consolidated from 
the date that control ceases. 
The acquisition method of accounting is used to account for business combinations by the Group (refer to Note 1(M)).  
Intercompany transactions, balances and unrealised gains on transactions between Group companies are eliminated.  
Unrealised losses are also eliminated unless the transaction provides evidence of the impairment of the asset transferred.  
Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by 
the Group. 
Investments in subsidiaries are accounted for at cost in the individual financial statements of the respective parent entity.  
These investments may have subsequently been written down to their recoverable amount determined by reference to the 
net assets of the subsidiaries as at 30 June each financial year where this is less than cost. 
Joint operations 
A joint operation is a joint arrangement whereby the participants that have joint control of the arrangement (i.e. joint 
operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. 
The Group recognises assets, liabilities, revenues and expenses according to its share in the assets, liabilities, revenues and 
expenses of a joint operation or similar as determined and specified in contractual arrangements (Joint Operating 
Agreements).  Details of major joint operation interests and the sum of the Group’s interests in joint operation assets, 
liabilities, revenue and expenses are set out in Note 28. 
Where part of a joint operation interest is farmed out in consideration of the farmee undertaking to incur further expenditure 
on behalf of both the farmee and the entity in the joint operation area of interest, exploration expenditure incurred and 
carried forward prior to farm-out continues to be carried forward without adjustment, unless the terms of the farm-out are 
excessive based on the diluted interest retained.  An impairment provision is then made to reduce exploration expenditure 
to its estimated recoverable amount.  Any cash received in consideration for farming out part of a joint operation interest is 
recognised in the profit or loss. 
D.
Crude oil and gas inventory and materials in inventory 
Crude oil and gas inventories, produced but not sold, are valued at the lower of cost and net realisable value.  Cost comprises 
a relevant proportion of all fixed and variable production, overhead, restoration and amortisation expenses and is determined 
on an average cost basis. 
Stocks of materials inventory, consumable stores and spare parts are carried at the lower of cost and net realisable value, 
with cost primarily determined on a weighted average cost basis. 
E.
Operating segment reporting 
Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision 
maker.  The chief operating decision maker, who is responsible for allocating resources and assessing performance of the 
operating segments, has been identified as the Board of Directors. 
F.
Foreign currency translation 
[i]
Functional and presentation currency 
Items included in the financial statements of each of the Group’s subsidiaries are measured using the currency of the primary 
economic environment in which the subsidiary operates (the ‘functional currency’).  The consolidated financial statements 
are presented in United States dollars, which is Horizon’s presentation currency.  Horizon has selected United States dollars 
as its presentation currency for the following reasons: 
(a) a significant portion of Horizon’s activity is denominated in United States dollars; and 
(b) it is widely understood by Australian and international investors and analysts. 
[ii] Transactions and balances 
Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates 
of the transactions.  Foreign exchange gains and losses resulting from the settlement of such transactions and from the 
translation at financial year end exchange rates of monetary assets and liabilities denominated in foreign currencies are 
HORIZON OIL ANNUAL REPORT 2024
56

generally recognised in the profit or loss.  They are deferred in equity if they relate to qualifying cash flow hedges and 
qualifying net investment hedges or are attributable to part of the net investment in a foreign operation. 
[iii] Group companies
All Group subsidiaries, except for Horizon Australia Energy Pty Ltd have a functional currency of United States dollars. 
Horizon Australia Energy Pty Ltd has a functional currency of Australian dollars (AUD).  The results and financial position of 
this entity has a functional currency different from the presentation currency and is translated into the presentation currency 
as follows: 
– assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of
that statement of financial position;
– income and expenses for each statement of profit or loss and statement of comprehensive income are translated at
average exchange rates (unless this is not a reasonable approximation of the cumulative effect of the rates prevailing on
the transaction dates, in which case income and expenses are translated at the dates of the transactions); and
– all resulting exchange differences are recognised in other comprehensive income.
G.
Revenue recognition
Revenue arises from the sale of crude oil and gas.  To determine whether to recognise revenue, the Group follows a 5-step 
process: 
[1] - 
Identifying the contract with a customer;
[2] - 
Identifying the performance obligations;
[3] - 
Determining the transaction price;
[4] - 
Allocating the transaction price to the performance obligations; and
[5] - 
Recognising revenue when/as performance obligation(s) are satisfied.
The Group enters into sales transactions involving two products.  The total transaction price for a contract is allocated 
amongst the various performance obligations based on their relative stand-alone selling prices.  The transaction price for a 
contract excludes any amounts collected on behalf of third parties.  Revenue is recognised either at a point in time or over 
time, when (or as) the Group satisfies performance obligations by transferring the promised goods to its customers. 
Revenue from Block 22/12, China, is derived over a period in time as the crude oil produced continuously flows through a 
metered pipeline.  The metered monthly production is invoiced at the end of each month, in accordance with a monthly 
sales contract, and revenue recognised for the month of production.  At the end of each month, once billing occurs and 
revenue is recognised, there are no unsatisfied performance obligations or variable revenue requiring estimation.  
Revenue from the Maari/Manaia fields, New Zealand, is derived at a point in time as the crude oil produced is stored and sold 
in individual liftings which are pursuant to individual sales contracts.  Each lifting is invoiced in accordance with the 
respective contract and revenue recognised based on the bill of lading date associated with the lifting.  Once the lifting is 
complete there are no unsatisfied performance obligations or variable revenue requiring estimation.  
Revenue from Mereenie, Australia, is derived at a point in time based on volumes sold under contracts with customers. 
Performance obligations are met when the product, either gas or oil is delivered to a specified measurement point (gas) or 
the point of load-out from third party storage facilities (liquids/oil).  Upon completion there are no unsatisfied performance 
obligations or variable revenue requiring estimation. 
The Group recognises contract liabilities for consideration received in respect of unsatisfied performance obligations and 
reports these amounts as other liabilities in the statement of financial position.  Similarly, if the Group satisfies a 
performance obligation before it receives the consideration, the Group recognises either a contract asset or a receivable in 
its statement of financial position, depending on whether something other than the passage of time is required before the 
consideration is due.  
H.
Taxation
[i]
Income tax
The income tax expense or revenue for the reporting period is the tax payable on the current period’s taxable income based 
on the applicable income tax rate for each jurisdiction adjusted by changes in deferred tax assets and liabilities attributable 
to temporary differences between the tax bases of assets and liabilities and their carrying amounts in the financial 
statements, and to unused tax losses. 
The current income tax charge is calculated on the basis of the tax laws enacted or substantially enacted at the end of the 
reporting period in the countries where the Company’s subsidiaries operate and generate taxable income.  It establishes 
provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. 
HORIZON OIL ANNUAL REPORT 2024
57

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of 
assets and liabilities and their carrying amounts in the financial statements.  Deferred income tax is determined using tax 
rates (and laws) that have been enacted or substantially enacted by the end of the reporting period and are expected to 
apply when the related deferred income tax asset is realised, or deferred income tax liability is settled. 
Deferred tax assets are recognised for deductible temporary differences and unused tax losses only if it is probable that 
future taxable amounts will be available to utilise those temporary differences and losses. 
Deferred tax liabilities and assets are not recognised for temporary differences between the carrying amount and tax bases 
of investments in subsidiaries where the parent entity is able to control the timing of the reversal of the temporary 
differences and it is probable that the differences will not reverse in the foreseeable future. 
Current and deferred tax is recognised in profit or loss, except to the extent that it relates to items recognised in other 
comprehensive income or directly in equity.  In this case, the tax is also recognised in other comprehensive income or directly 
in equity, respectively.  
[ii] Government royalties
Government royalties are treated as taxation arrangements when they are imposed under Government authority and when 
the calculation of the amount payable is derived from a measure of profit that falls within the definition of ‘taxable profit’ for 
the purposes of AASB 112 Income Taxes.  Current and deferred tax is then provided on the same basis as described in (i) 
above.  Royalty arrangements that do not meet the criteria for treatment as a tax are recognised on an accruals basis. 
I.
Leases
The Group leases an office in Sydney and various equipment, with rental contracts typically taken out for fixed periods of 
12 months to 3 years.  These contracts do not have a reasonably certain extension option and may contain both lease and 
non-lease components.  The Group allocates the consideration in the contract to the lease and non-lease components 
based on their relative stand-alone prices.  Lease terms are negotiated on an individual basis, and do not impose any 
covenants other than the security interests in the leased assets that are held by the lessor. 
Assets and liabilities arising from a lease are initially measured on a present value basis.  Lease liabilities include the net 
present value of the following lease payments: 
– fixed payments (including in-substance fixed payments), less any lease incentives receivable; and
– variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the
commencement date
The lease payments are discounted using the interest rate implicit in the lease.  If that rate cannot be readily determined, 
the lessee’s incremental borrowing rate is used, being the rate that the individual lessee would have to pay to borrow the 
funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with similar 
terms, security and conditions.  The weighted average lessee’s incremental borrowing rate applied to the lease liabilities is 
4.5%. 
Lease payments are allocated between principal and finance cost.  The finance cost is charged to profit or loss over the 
lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. 
Right-of-use assets are measured at cost and are depreciated over the shorter of the asset's useful life and the lease term 
on a straight-line basis. 
J.
Impairment of assets
Assets are reviewed for impairment at each reporting date to determine whether there is any indication of impairment.  If an 
impairment indicator exists a formal estimate of the recoverable amount is calculated.  Intangible assets with an indefinite 
useful life are assessed for impairment regardless of whether there are any indicators of impairment.  An impairment loss is 
recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount.  The recoverable amount 
is the higher of an asset’s fair value less costs to sell and value in use.  For the purposes of assessing impairment, assets 
are grouped at the lowest levels for which there are separately identifiable cash inflows which are largely independent of the 
cash inflows from other assets or groups of assets (‘cash-generating units’). 
In assessing the recoverable amount, an asset’s estimated future pre-tax cash flows are discounted to their present value 
using an pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific 
to the asset.   
Exploration phase expenditure is assessed for impairment in accordance with Note1(N). 
HORIZON OIL ANNUAL REPORT 2024

K.
Cash and cash equivalents 
For presentation purposes in the statement of cash flows, cash and cash equivalents includes cash at banks and on hand 
(including share of joint operation cash balances), deposits held at call with financial institutions, other short-term, highly 
liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and 
which are subject to an insignificant risk of changes in value, and bank overdrafts.  Bank overdrafts are shown within 
borrowings in current liabilities in the consolidated statement of financial position. 
L.
Trade receivables 
Trade receivables are recognised initially at fair value and subsequently measured at amortised cost, less provision for 
doubtful debts.  Trade receivables are generally due for settlement within 30 days from the date of recognition.  They are 
included in current assets, except for those with maturities greater than one year after the end of the reporting period which 
are classified as non-current assets. 
The group applies the AASB 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade receivables.  The expected loss rates are based on the payment profiles of sales over a period of 
36 months before 30 June 2024 and the corresponding historical credit losses experienced within this period.  The historical 
rates are adjusted to reflect current and forward-looking information on key factors affecting the ability of the customers to 
settle the receivables.  Management assesses the collectability of these amounts based on the customer relationships and 
historical payment behaviour. 
M.
Business combinations 
The acquisition method of accounting is used to account for all business combinations, regardless of whether equity 
instruments or other assets are acquired.  The consideration transferred for the acquisition of a subsidiary comprises the 
fair values of the assets transferred, the liabilities assumed, equity interests issued by the Group, fair value of any asset or 
liability resulting from a contingent consideration arrangement, and fair value of any pre-existing equity interest in the 
subsidiary.  Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are, with 
limited exceptions, measured initially at their fair values at the acquisition date.  Acquisition related costs are expensed as 
incurred. 
For purchase combinations which do not constitute the acquisition of a business, the Group identifies and recognises the 
individual identifiable assets acquired and liabilities assumed.  The consideration paid is allocated to the individual 
identifiable assets and liabilities on the basis of their relative fair values at the date of purchase.  Acquisition related costs 
are capitalised. 
N.
Exploration phase expenditure 
Exploration phase expenditure in respect of each area of interest is accounted for using the successful efforts method of 
accounting.  The successful efforts method requires all exploration phase expenditure to be expensed in the period it is 
incurred, except the costs of successful wells, the costs of acquiring interests in new exploration assets and pre-
development costs where there is a high degree of probability that the development will go ahead, which are capitalised.  
Costs directly associated with the drilling of exploration wells and any associated geophysical and geological costs are 
initially capitalised pending determination of whether potentially economic reserves of hydrocarbons have been discovered.  
Business development costs such as the review of farm in opportunities and bid rounds are expensed in the period in which 
they are incurred.  Areas of interest are recognised at the cash-generating unit level, being the smallest grouping of assets 
generating independent cash flows which usually is represented by an individual oil or gas field. 
When an oil or gas field has been approved for development, the capitalised exploration phase expenditure is reclassified as 
oil and gas assets in the statement of financial position.  Prior to reclassification, capitalised exploration phase expenditure 
is assessed for impairment. 
Where an ownership interest in an exploration and evaluation asset is purchased, any cash consideration paid net of 
transaction costs is treated as an asset acquisition.  Alternatively, where an ownership interest is sold, any cash 
consideration received net of transaction costs is treated as a recoupment of costs previously capitalised, with any excess 
accounted for as a gain on disposal of non-current assets. 
Impairment of capitalised exploration phase expenditure 
Exploration phase expenditure is reviewed for impairment semi-annually in accordance with the requirements of AASB 6 
Exploration for and Evaluation of Mineral Resources.  The carrying value of capitalised exploration phase expenditure is 
assessed for impairment at the asset or cash-generating unit level (which usually is represented by an exploration permit or 
licence) whenever facts and circumstances (as defined in AASB 6) suggest that the carrying amount of the asset may exceed 
its recoverable amount.  If any indication of impairment exists, an estimate of the asset’s recoverable amount is calculated. 
 
HORIZON OIL ANNUAL REPORT 2024
59

An impairment loss exists when the carrying amount of an asset or cash-generating unit exceeds its estimated recoverable 
amount.  The asset or cash-generating unit is then written-down to its recoverable amount.  Impairment losses are 
recognised as an expense in profit or loss. 
Capitalised exploration phase expenditure that suffered impairment is tested for possible reversal of the impairment loss 
whenever facts or changes in circumstances indicate that the impairment may have reversed. 
O.
Oil and gas assets 
[i]
Development expenditure 
Development expenditure is stated at cost less any accumulated impairment losses.  Development expenditure incurred by 
or on behalf of the Group is accumulated separately for fields in which proven and probable hydrocarbon reserves have been 
identified to the satisfaction of directors.  Such expenditure comprises direct costs and overhead expenditure incurred which 
can be directly attributable to the development phase or is acquired through the acquisition of a permit. 
Once a development decision has been taken on an oil or gas field, the carrying amount of the relevant exploration and 
evaluation expenditure in respect of the relevant area of interest is aggregated with the relevant development expenditure. 
Development expenditure is reclassified as ‘production assets’ at the end of the commissioning phase, when the oil or gas 
field is capable of operating in the manner intended by management (that is, when commercial levels of production are 
capable of being achieved). 
Development expenditure is tested for impairment in accordance with the accounting policy set out in Note 1(J). 
[ii] Production assets 
When further development costs are incurred in respect of a production asset after the commencement of production, such 
expenditure is carried forward as part of the production asset when it is probable that additional future economic benefits 
associated with the expenditure will flow to the Group.  Otherwise such expenditure is classified as production expense in 
income statements when incurred. 
Production assets are stated at cost less accumulated amortisation and any accumulated impairment losses. 
Once commercial levels of production commence, amortisation is charged using the unit-of-production method.  The unit-
of-production method results in an amortisation expense proportional to the depletion of proven and probable hydrocarbon 
reserves for the field.  Production assets are amortised by area of interest in the proportion of actual production for the 
financial period to the proven and probable hydrocarbon reserves of the field.   
The cost element of the unit-of-production calculation is the capitalised costs incurred to date for the field together with 
the estimated / anticipated future development costs (stated at current financial period-end using unescalated prices) of 
obtaining access to all the proven and probable hydrocarbon reserves included in the unit-of-production calculation. 
Production assets are tested for impairment in accordance with the accounting policy set out in Note 1(J). 
[iii] Restoration provision 
The estimated costs of decommissioning and removing an asset and restoring the site are included in the cost of the asset 
as at the date the obligation first arises and to the extent that it is first recognised as a provision.  This asset is subsequently 
amortised on a unit-of-production basis. 
The corresponding provision is reviewed at the end of each reporting period.  The provision is measured at the best estimate 
of the present value amount required to settle the present obligation at the end of the reporting period, based on current 
legal and other requirements and technology, discounted where material using market yields at the balance sheet date on 
Treasury bonds with terms to maturity and currencies that match, as closely as possible, to the estimated future cash 
outflows. 
Where there is a change in the expected restoration, rehabilitation or decommissioning costs, an adjustment is recorded 
against the carrying value of the provision and any related restoration asset, and the effects are recognised in profit or loss 
on a prospective basis over the remaining life of the operation. 
The unwinding of the effect of discounting on the restoration provision is included within finance costs in profit or loss. 
 
HORIZON OIL ANNUAL REPORT 2024
60

[iv] Reserves 
The estimated reserves include those determined on an annual basis by Mr Gavin Douglas, Chief Operating Officer of Horizon.  
Mr Douglas is a full-time employee of Horizon and is a member of the American Association of Petroleum Geologists.  
Mr Douglas’ qualifications include a Master of Reservoir Evaluation and Management from the Heriot Watt University, UK and 
more than 25 years of relevant experience.  The reserve estimates are determined by Mr Douglas based on assumptions, 
interpretations, and assessments.  These include assumptions regarding commodity prices, foreign exchange rates, 
operating costs and capital expenditures, and interpretations of geological and geophysical models to make assessments 
of the quantity of hydrocarbons and anticipated recoveries. 
P.
Investments and other financial assets 
Subsidiaries are accounted for in the consolidated financial statements as set out in Note 1(C). 
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an 
active market.  They arise when the Group provides money, goods or services directly to a debtor with no intention of selling 
the receivable.  They are included in current assets, except for those with maturities greater than 12 months after the end of 
the reporting period which are classified as non-current assets.  Loans and receivables are included in receivables in the 
statement of financial position. 
The Group classifies other financial assets in the following measurement categories: 
– - those to be measured subsequently at fair value (either through OCI or profit or loss), and 
– - those to be measured at amortised cost 
For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI.  
 
Equity instruments 
At initial recognition, Group’s management has elected to measure its equity instruments at fair value through other 
comprehensive income (FVOCI).  The group subsequently measures all equity investments as fair value.  Where the group’s 
management has elected to present fair value gains and losses on equity instruments in OCI, there is no subsequent 
reclassification of fair value gains and losses to profit or loss following the derecognition of the investment.   
Q.
Plant and equipment 
The cost of improvements to, or on, leasehold property is depreciated over the unexpired period of the lease or the estimated 
useful life of the improvement to the Group, whichever is shorter. 
Depreciation on other assets is calculated using the straight-line method to allocate their cost or revalued amounts, net of 
their residual values, over their estimated useful lives, as follows: 
– Computer equipment 
3 – 4 years 
– Furniture, fittings and equipment 
3 – 10 years 
The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of the reporting period. 
An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater 
than its estimated recoverable amount. 
Gains and losses on disposals are determined by comparing proceeds with carrying amount.  These are included in profit or 
loss. 
R.
Intangible assets 
[i]
New Zealand carbon credits 
New Zealand carbon credits, also referred to as New Zealand Units (NZUs) are acquired through the Environmental Protection 
Authority and surrendered to the New Zealand Government for the Group’s proportionate share of the Maari/Manaia fields 
direct greenhouse gas emissions for the calendar year.  The NZUs are valued at cost and do not expire.  
NZUs are not amortised but are tested for impairment in accordance with the accounting policy set out in Note 1(J). 
S.
Trade and other payables 
These amounts represent liabilities for goods and services provided to the Group prior to the end of financial year which are 
unpaid.  Due to their short-term nature they are not discounted.  The amounts are unsecured and are usually paid within 
HORIZON OIL ANNUAL REPORT 2024
61

30 days of recognition.  They are included in current liabilities, except for those with maturities greater than one year after 
the end of the reporting period which are classified as non-current liabilities. 
T.
Derivatives 
Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently 
remeasured to their fair value at each reporting date.  The accounting for subsequent changes in fair value depends on 
whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.  The Group 
designates certain derivatives as either; (1) hedges of the fair value of recognised assets or liabilities or a firm commitment 
(fair value hedge); or (2) hedges of the cash flows of recognised assets and liabilities and highly probable forecast 
transactions (cash flow hedges).  The Group currently does not have any derivatives designated as fair value hedges. 
The Group documents at the inception of the hedging transaction the relationship between hedging instruments and hedged 
items, as well as its risk management objective and strategy for undertaking various hedge transactions.  The Group also 
documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in 
hedging transactions have been and will continue to be highly effective in offsetting changes in fair values or cash flows of 
hedged items. 
The fair values of derivative financial instruments used for hedging purposes are disclosed in Note 10.  Movements in the 
hedging reserve in equity are shown in Note 23(A). 
[i]
Cash flow hedge 
The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is 
recognised in equity in the hedging reserve.  The gain or loss relating to the ineffective portion is recognised immediately in 
profit or loss within other income or other expenses. 
Amounts accumulated in equity are recycled to profit or loss in the periods when the hedged item will affect profit or loss 
(for instance when the forecast sale that is hedged takes place).  The gain or loss relating to the effective portion of interest 
rate swaps hedging variable rate borrowings is recognised in profit or loss within “finance costs”.  The gain or loss relating 
to the effective portion of forward foreign exchange contracts and commodity price contracts hedging export sales is 
recognised in profit or loss within ‘sales’.  However, when the forecast transaction that is hedged results in the recognition 
of a non-financial asset (for example, inventory) or a non-financial liability, the gains and losses previously deferred in equity 
are transferred from equity and included in the measurement of the initial cost or carrying amount of the asset or liability. 
When a hedging instrument expires or is sold or terminated, or when a hedge no longer meets the criteria for hedge 
accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the forecast 
transaction is ultimately recognised in profit or loss. 
When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is 
immediately transferred to the profit or loss. 
[ii] Derivatives that do not qualify for hedge accounting 
Certain derivative instruments do not qualify for hedge accounting.  Changes in the fair value of any derivative instrument 
that does not qualify for hedge accounting are recognised immediately in profit or loss and are included in other income or 
other expenses. 
U.
Borrowings 
Borrowings are initially recognised at fair value, net of transaction costs incurred.  Borrowings are subsequently measured 
at amortised cost.  Any difference between the proceeds (net of transaction costs) and the redemption amount is recognised 
in profit or loss over the period of the borrowings using the effective interest rate method.  Fees paid on the establishment 
of loan facilities which are not an incremental cost relating to the actual drawdown of the facility, are recognised as 
prepayments (netted against the loan balance) and amortised on a straight-line basis over the term of the facility. 
Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability 
for at least 12 months after the end of the reporting period. 
V.
Borrowing costs 
Borrowing costs which includes the costs of arranging and obtaining financing, incurred for the acquisition or construction 
of any qualifying asset are capitalised during the period of time that is required to complete and prepare the asset for its 
intended use or sale.  Other borrowing costs are expensed when incurred. 
No borrowing costs (2023: US$Nil) were capitalised during the current financial year and the amount of borrowing costs 
amortised to the income statement were US$709,199 (2023: US$1,001,234).

W.
Employee benefits 
[i]
Wages and salaries and annual leave 
Liabilities for wages and salaries, including non-monetary benefits, annual leave and related on-costs expected to be settled 
within 12 months of the end of the reporting period are recognised in other payables in respect of employees' services up to 
the end of the reporting period and are measured at the amounts expected to be paid when the liabilities are settled.  The 
liabilities are recognised in other payables. 
[ii] Long service leave 
The liability for long service leave is recognised as a provision for employee benefits and measured as the present value of 
expected future payments to be made in respect of services provided by employees up to the end of the reporting period 
using the projected unit credit method.  Consideration is given to expected future wage and salary levels, experience of 
employee departures and periods of service.  Expected future payments are discounted using market yields at the end of 
the reporting period on national government bonds with terms to maturity and currency that match, as closely as possible, 
the estimated future cash outflows. 
[iii] Share-based payments 
Share-based payment compensation benefits are provided to employees and consultants via the Horizon Long-Term 
Incentive Plan, the Horizon Employee Option Scheme, and the General Option Plan.  Information relating to these schemes 
is set out in Note 32. 
The fair value of performance rights and share appreciation rights (‘SARs’) granted under the Horizon Long-Term Incentive 
Plan and Horizon Employee Option Scheme are recognised as an employee share-based payments expense with a 
corresponding increase in equity.  The total amount to be expensed is determined by reference to the fair value of the 
performance rights and SARs granted, which includes any market performance conditions but excludes the impact of any 
service and non-market performance vesting conditions and the impact of any non-vesting conditions.  Non-market 
performance vesting conditions are included in assumptions about the number of performance rights and SARs that are 
expected to vest. 
The fair value is measured at grant date.  The total expense is recognised over the vesting period, which is the period over 
which all of the specified vesting conditions are to be satisfied.  At the end of each reporting period, the Group revises its 
estimates of the number of performance rights and SARs that are expected to vest based on the non-market performance 
vesting conditions.  It recognises the impact of the revision to original estimates, if any, in profit or loss, with a corresponding 
adjustment to equity. 
The fair value at grant date is independently determined using either a Black-Scholes or Monte Carlo simulation option 
pricing model that takes into account the exercise price, the term of the option or SAR, the impact of dilution, the share price 
at effective allocation date and expected price volatility of the underlying share, the expected dividend yield and the risk-
free interest rate for the term of the performance right or SAR. 
The Company has elected to retain any amounts originally recognised in the share-based payments reserve, regardless of 
whether the associated performance rights are cancelled or lapse unexercised. 
The Horizon Oil Employee Incentive Trust administers the Long-Term Incentive Plan and Horizon Oil Employee Option 
Scheme.  The Horizon Oil Employee Incentive Trust is consolidated in accordance with the principles in Note 1(C).  
Where the Horizon Oil Employee Incentive Trust purchases the company’s equity instruments, the consideration paid, 
including any directly attributable incremental costs (net of income taxes) is deducted from equity reserves.  When an 
employee exercises performance rights pursuant to the Long-Term Incentive Plan or Employee Option Scheme, and the 
Board resolves to settle in shares, the Horizon Oil Employee Oil Incentive Trust transfers the appropriate amount of shares to 
the employee.  
X.
Contributed equity 
Ordinary shares are classified as equity. 
Incremental costs directly attributable to the issue of new ordinary shares or options over unissued ordinary shares are 
shown in share capital as a deduction, net of related income tax, from the proceeds.  Incremental costs directly attributable 
to the issue of new shares or options for the acquisition of a business are not included in the cost of the acquisition as part 
of the purchase consideration but are expensed. 
Where the Group purchases the company’s equity instruments, for example as the result of a share buy-back, the 
consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity 
HORIZON OIL ANNUAL REPORT 2024
63

attributable to the owners of Horizon as treasury shares until the shares are cancelled or reissued.  Where such ordinary 
shares are subsequently reissued, any consideration received, net of any directly attributable incremental transaction costs 
and the related income tax effects, is included in equity attributable to the owners of Horizon.  
Y.
Earnings per share 
[i]
Basic earnings per share 
Basic earnings per share is calculated by dividing the profit attributable to equity holders of the Company, excluding any 
costs of servicing equity other than ordinary shares, by the weighted average number of ordinary shares outstanding during 
the financial year, adjusted for bonus elements in ordinary shares issued during the financial year. 
[ii] Diluted earnings per share 
Diluted earnings per share adjusts the figures used in the determination of basic earnings per share to take into account the 
after income tax effect of interest and other financing costs associated with dilutive potential ordinary shares and the 
weighted average number of shares assumed to have been issued for no consideration in relation to dilutive potential 
ordinary shares.  Potential ordinary shares are considered dilutive only when their conversion to ordinary shares would 
decrease earnings per share, or increase loss per share, from continuing operations.  
Z.
Goods and Services Tax (‘GST’) 
Revenues, expenses and assets are recognised net of the amount of associated GST, unless the GST incurred is not 
recoverable from the taxation authority.  In this case it is recognised as part of the cost of acquisition of the asset or as part 
of the expense. 
Receivables and payables are stated inclusive of the amount of GST receivable or payable.  The net amount of GST 
recoverable from, or payable to, the taxation authority is included with other receivables or payables in the statement of 
financial position. 
Cash flows are presented on a gross basis.  The GST components of cash flows arising from investing or financing activities 
which are recoverable from, or payable to the taxation authority, are presented as operating cash flow. 
AA. Parent entity financial information 
The financial information for the parent entity, Horizon Oil Limited, disclosed in Note 40, has been prepared on the same 
basis as the consolidated financial statements, except as set out below. 
[i]
Investments in subsidiaries, associates and joint venture entities 
Investments in subsidiaries, associates and joint venture entities are accounted for at cost in the financial statements of 
Horizon Oil Limited.  Dividends received from associates are recognised in the parent entity’s profit or loss, rather than being 
deducted from the carrying amount of these investments. 
[ii] Financial guarantees 
Where the parent entity has provided financial guarantees in relation to loans and payables of subsidiaries for no 
compensation, the fair values of these guarantees are accounted for as contributions and recognised as part of the cost of 
the investment. 
Note 2
Critical accounting estimates and judgements 
This section considers estimates and judgements which are continually evaluated and are based on historical experience 
and other factors, including expectations of future events that may have a financial impact on the Group and that are 
believed to be reasonable under the circumstances.  
A.
Critical accounting estimates and assumptions 
The Group makes estimates and assumptions concerning the future.  The resulting accounting estimates will, by definition, 
seldom equal the related actual results.  The most significant estimates and assumptions that have a significant risk of 
causing a material adjustment to the carrying amount of assets and liabilities relate to: 
[i]
Exploration and evaluation assets 
The Group’s policy for exploration and evaluation expenditure is discussed in Note 1(N).  The application of this policy requires 
management to make certain estimates and assumptions as to future events and circumstances.  These estimates and 
HORIZON OIL ANNUAL REPORT 2024
64

assumptions include whether commercially viable reserves have been found and whether the capitalised exploration and 
evaluation expenditure will be recovered through future exploitation or sale.   
[ii] Reserve estimates
The estimated quantities of proven and probable hydrocarbons reported by the Group are integral to the calculation of 
amortisation expense (depletion), assessments of impairment of assets, provision for restoration and the recognition of 
deferred tax assets due to changes in expected future cash flows.  Reserve estimates require interpretation of complex and 
judgemental geological and geophysical models in order to make an assessment of the size, shape, depth and quality of 
reservoir, and their anticipated recoveries.  The economic, geological and technical factors used to estimate reserves may 
change from period to period.  Reserve estimates are prepared in accordance with guidelines prepared by the Society of 
Petroleum Engineers. 
[iii] Provisions for restoration
The Group estimates the future removal and restoration costs of petroleum production facilities, wells, pipelines and related 
assets at the time of installation of the assets and reviews these assessments periodically.  In most instances the removal 
of these assets will occur well into the future.  The estimate of future removal costs therefore requires management to make 
judgements around the timing of the required restoration, rehabilitation and decommissioning activities, as well as the 
discount rate.  The carrying amount of the provision for restoration is disclosed in Note 20. 
New Zealand, Maari Restoration  
During the financial year the Group revised the discount, inflation and foreign exchange rates used in quantifying the New 
Zealand restoration provision.  The resultant effect is decrease in the restoration provision and rehabilitation asset of US$1.3 
million.   
Australia, Mereenie Restoration  
During the financial year, following the acquisition of 25% interest in the Mereenie oil and gas fields, the Group recognised 
US$7.0 million future costs of restoring the operating sites at Mereenie.   
[iv] Impairment of oil and gas assets
The Group assesses whether its oil and gas assets are impaired on a semi-annual basis when an indicator of impairment is 
present.  This includes an estimation of the recoverable amount of the cash generating unit to which each asset belongs. 
The recoverable amount of an asset is the higher of its fair value less cost to sell and value in use.  The fair value less cost 
to sell is assessed on the basis of the estimated net cash flows that will be received from the asset’s continued employment 
and subsequent disposal.  The estimated future cash flows are based on estimates of hydrocarbon reserves, future 
production profiles, commodity prices, operating costs and future development costs necessary to access the reserves. 
Current climate change legislation is also factored into the estimated future cashflows and future uncertainty created by 
climate change risks continue to be monitored.  In most cases, the present value of future cashflows is most sensitive to 
estimates of future oil price, reserves, and production rates.   
[v] Share-based payments
Share-based payment transactions with directors and employees are measured by reference to the fair value of the share 
performance rights and employee options at the date they were granted.  The fair value is ascertained using an appropriate 
pricing model, being either the Black-Scholes or Monte Carlo simulation, depending on the terms and conditions upon which 
the share performance rights and employee options were granted.  The Group also applies assumptions around the likelihood 
of the share performance rights or options vesting which will have an impact on the expense and equity recorded in the 
financial year.  The number of share performance rights and employee options outstanding are disclosed in Note 32. 
[vi] Recoverability of deferred tax assets
The recoverability of deferred tax assets is based on the probability that future taxable amounts will be available to utilise 
those temporary differences and losses.  The Group has not recognised deferred tax assets in respect of some tax losses 
and temporary tax differences at this point in time.  Whilst the recently acquired Mereenie gas field is expected to generate 
future Australian taxable income for the Australian tax consolidated group, the recognition of these tax losses as deferred 
tax assets will be reassessed once longer-term income and expenditure information from the acquisition is available to the 
Company. 
Assessing the future utilisation of tax losses and temporary tax differences requires the Group to make significant estimates 
related to expectations of future taxable income.  Estimates of future taxable income are based on forecast cash flows from 
operations and the application of existing tax laws.  To the extent that future utilisation of these tax losses and temporary 
HORIZON OIL ANNUAL REPORT 2024
65

tax differences becomes probable, this could result in significant changes to deferred tax assets recognised, which would 
in turn impact future financial results.   
B.
Critical judgements in applying the Group’s accounting policies
No critical judgements considered to have a significant risk of causing a material adjustment to the carrying amounts of the 
assets and liabilities within the next financial year were made during the preparation of this report.

Segment information 
A.
Description of segments
Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision 
maker.  The chief operating decision maker has been identified as the Board of Directors. 
The operating segments identified are broadly based on the Group’s working interest in each individual oil and gas permit, 
arranged by developmental phase.  Discrete pre-tax financial information (including pre-tax operating profit and capital 
expenditure on exploration and evaluation assets and oil and gas assets) for each oil and gas permit is prepared and provided 
to the chief operating decision maker on a regular basis.  In certain circumstances, individual oil and gas permits are 
aggregated into a single operating segment where the economic characteristics and long-term planning and operational 
considerations of the individual oil and gas permits are such that they are considered interdependent.  The Group has 
identified three operating segments: 
– China development – the Group is currently involved in developing and producing crude oil from the Block 22/12 – WZ6-12,
WZ12-8W and WZ12-8E oil field developments and in the exploration and evaluation of hydrocarbons within Block 22/12;
– New Zealand development – the Group is currently involved in developing and producing crude oil from the Maari/Manaia
oil field development; and
– Australia development – the Group is currently involved in developing and producing oil and gas from the Mereenie OL4
and OL5 oil and gas fields.

The Group is party to derivative financial instruments in the normal course of business in order to hedge exposure to oil price, 
interest rate and foreign exchange fluctuations in accordance with the Group’s financial risk management policies (refer to 
Note 24a.  
Oil price swap contracts (cash flow hedges) 
During the financial year, oil price hedging was undertaken as a risk mitigation measure to mitigate the concentration of oil 
price exposure on Maari liftings whereby oil is produced over an approximate three month period, but sold subject to the 
average oil price in the month which it is lifted. At 30 June 2024, the Group had 50,000 bbls of crude oil hedged through Brent 
oil price swaps at a weighted average price of US$83.91/bbl.  
The gain or loss arising from re-measurement of the hedge-accounted instruments at fair value is deferred in equity in the 
hedging reserve, to the extent that the hedge is effective, and re-classified into profit or loss when the hedged transaction 
is recognised.  The ineffective portion is recognised in profit or loss immediately.  During the financial year, a net loss of 
US$139,000 (2023: net gain of US$1,556,180) was transferred to profit or loss.

1 The Group acquires New Zealand Units ((NZUs) also referred to as carbon credits) to surrender to the New Zealand Government through the Environmental 
Protection Authority, for its proportionate share of the Maari/Manaia fields direct greenhouse gas emissions for the calendar year.  NZUs are tradable 
instruments with transactions taking place on the New Zealand Emissions Trading Register, which is operated by the Environmental Protection Authority.  
The NZUs are recorded at cost and are not amortised and are tested for impairment at each balance sheet date.   
2 The Company’s obligation for the 2023 calendar year was settled in May 2024 whereby a portion of the NZU’s on hand were surrendered to the 
Environmental Protection Authority.

1  The ETS liability represents Horizon Oil International Limited’s obligation to the New Zealand Government for the company’s proportionate share of the 
Maari/Manaia fields greenhouse gas emissions.  Refer to Note 12 for the disclosure of the carbon credits acquired (NZUs) which will be surrendered to the 
New Zealand Government for settlement of this obligation.  The ETS obligation is recorded at the cost of the units acquired to settle the obligation.  When 
the number of units required to settle the obligation exceeds the units on hand, the excess will be accounted for at the cost of obtaining the incremental 
units required to settle the obligation. 
2  A deferred payment of A$5 million was payable to Macquarie as purchase consideration for the acquisition of Mereenie oil and gas fields (refer Note 26). 
Full payment was made in July 2024. 
3  A future payment of A$4 million is payable to Macquarie as purchase consideration for the acquisition of Mereenie oil and gas fields subject to certain 
conditions being met.

Bank loans – Debt Facility
On 31 July 2023, the Cash Advance Facility with ANZ, Westpac and ICBC was repaid in full. 
On 4 June 2024, Horizon advised that it has executed a new AUD 42.5 million senior debt facility agreement with Macquarie 
Bank to fund the acquisition of the 25% non-operating interest in the OL4 and OL5 development licenses which contain the 
producing Mereenie conventional oil and gas field, Northern Territory, Australia. 
HORIZON OIL ANNUAL REPORT 2024
78

The new senior debt facility, is structured as a reserves base lending facility, has a term of 5 years with semi-annual 
repayments and attracts an interest rate of BBSW + 5%.  Lender security is limited to first ranking general security over the 
interest in Mereenie, with a parent company guarantee which is customary for a reserves base lending facility.  On 11 June 
2024, the Group reached financial close and draw down took place to fund the Mereenie acquisition.  
Under the facility, the facility limit is determined by applying a minimum facility life coverage ratio to the net present value 
of estimated future cash flows from the Mereenie oil and gas field.  Estimated future cash flows are dependent on, amongst 
other things, oil and gas prices, reserve estimates, operating and capital cost estimates.  The facility is secured by a floating 
charge over the shares and assets of the borrower (Horizon Australia Energy Limited which is a wholly owned subsidiary of 
Horizon Oil Limited).  Horizon Oil Limited has guaranteed the performance of Horizon Australia Energy Limited in relation to 
the loan facility from Macquarie Bank.  The Group is subject to covenants which are common for a facility of this nature. 
At 30 June 2024, total debt drawn under the facility was US$26.4 million (A$39.9 million).

Ordinary shares 
Fully paid 
Fully paid ordinary shares entitle the holder to participate in dividends and the proceeds on winding up of the Company in 
proportion to the number of shares held.  Voting rights are governed by the Company’s Constitution.  In summary, on a show 
of hands every holder of ordinary shares present at a meeting in person or by proxy is entitled to one vote and upon a poll 
each fully paid ordinary share is entitled to one vote. 
Partly paid 
Partly paid ordinary shares are issued on exercise of employee options.  The partly paid shares currently on issue are held 
by the Company following forfeiture by their original holder.  The outstanding obligation in relation to the partly paid ordinary 
shares is payable either when called or by the date not exceeding 5 years from the grant date of the option which gave rise 
to the partly paid ordinary share.  Partly paid ordinary shares entitle the holder to participate in dividends and the proceeds 
on winding up of the Company in proportion to the number of shares held.  Voting rights are governed by the Company’s 
Constitution.  In summary, on a show of hands every holder of partly paid ordinary shares present at a meeting in person or 
by proxy is entitled to one vote and upon a poll, is entitled to one vote to the proportion of the total issue price then paid up.

Nature and purpose of reserves
Share-based payment reserve: 
The fair value of performance rights and share appreciation rights granted to employees results in an increase in equity upon 
recognition of the corresponding employee benefits expense, as described in the accounting policy set out in Note 1(W)([iii]).  
The fair value of general options granted also results in an increase in equity unless accounting standards require the options 
to be treated otherwise. 
The Company has elected to retain any amounts originally recognised in the share-based payments reserve, regardless of 
whether the associated options or share appreciation rights are cancelled or lapse unexercised. 
Hedge reserve: 
Changes in the market value of the effective portion of derivatives is reflected directly in equity until such time as the hedge 
is ineffective or expires, as described in the accounting policy set out in Note 1(T). 
Treasury shares: 
Treasury shares are shares in Horizon that are held by the Horizon Employee Share Trust for the purpose of issuing shares 
under the Horizon Employee Option Scheme and the Horizon Long Term Incentive (LTI) Plan.  Refer to Note 32 for further 
information.  Shares issued to employees are recognised on a weighted average basis.

Currency translation reserve: 
Exchange differences arising on translation of Horizon Australia Energy Pty Ltd, from its functional currency of Australian 
dollars into the Group’s presentation currency of United States dollars, are recognised in other comprehensive income as 
described in the accounting policy set out in Note 1(F) and accumulated in a separate reserve within equity. 
Note 24 Financial risk management 
The Group's activities expose it to a variety of financial risks: market risk (including currency risk, interest rate risk and 
commodity price risk); credit risk; liquidity risk; capital risk; and climate related and other emerging risks.  The Group's overall 
risk management program focuses on the unpredictability of financial markets and seeks to minimise potential adverse 
effects on the financial performance of the Group.  The Group uses derivative financial instruments such as oil price swaps, 
interest rate swaps and foreign exchange forward contracts, to hedge certain risk exposures.  Derivatives are exclusively 
used for hedging purposes, i.e. not as trading or other speculative instruments.  The Group uses different methods to 
measure the different types of risk to which it is exposed.  These methods include sensitivity analysis in the case of interest 
rate, foreign exchange and commodity price risks, and aging analysis for credit risk. 
Risk management is carried out by the finance function under policies approved by the Board of Directors.  The finance 
function identifies, evaluates and if necessary hedges financial risks in close co-operation with Group management.  The 
board provides written principles for overall risk management, as well as written policies covering specific areas, such as 
mitigating foreign exchange, interest rate and credit risks and the use of derivative financial instruments. 
The Group has no off-balance sheet financial assets or liabilities as at the end of the reporting period.

A.
Market risk
[i]
Foreign exchange risk
Foreign exchange risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of 
changes in foreign exchange rates. 
Foreign exchange risk arises when future commercial transactions and recognised financial assets and financial liabilities 
are denominated in a currency that is not the Group’s functional currency. 
The Group operates internationally and is exposed to foreign exchange risk arising predominately from Australian and New 
Zealand dollars and Chinese Renminbi. 
The Group manages foreign exchange risk by monitoring forecast cash flows in currencies other than US dollars and ensuring 
that adequate Australian dollar and New Zealand dollar cash balances are maintained. 
The objective of the Group’s foreign exchange risk management policy is to ensure its financial viability despite potential 
periods of unfavourable exchange rates.  Regular sensitivity analysis is conducted to evaluate the potential impact of 
unfavourable exchange rates on the Group’s future financial position.  The results of this evaluation are used to determine 
the most appropriate risk mitigation tool to be used.  The Group will hedge when it is deemed the most appropriate risk 
mitigation tool to be used. 
As at 30 June 2024, the Group had no outstanding exchange rate hedges (30 June 2023: derivative asset of US$24,000). 
Effects of hedge accounting  
The effects of the foreign currency related hedging instruments on the Group’s financial position and performance are as

1 This has been based on the change in the exchange rate against the US dollar in the financial years ended 30 June 2024 and 30 June 2023.  The sensitivity 
analysis has been based on the sensitivity rates when reporting foreign exchange risk internally to key management personnel and represents 
management’s assessment of the possible change in foreign exchange rates based on historic volatility.  In management’s opinion, the sensitivity 
analysis is not fully representative of the inherent foreign exchange risk as the end of the reporting period exposure does not necessarily reflect the 
exposure during the course of the financial year. 
[ii] Commodity price risk
Commodity price risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of 
change in market commodity prices for crude oil. 
The objective of the Group’s commodity price risk management policy is to ensure its financial viability despite potential 
periods of unfavourable prices.  Regular sensitivity analysis is conducted to evaluate the potential impact of unfavourable 
prices on the Group’s future financial position.  The results of this evaluation are used to determine the most appropriate risk 
mitigation tool to be used.  The Group will hedge when it is deemed the most appropriate risk mitigation tool to be used or 
where required by its financing arrangements.  During the current financial year, oil price hedging was undertaken as a risk 
mitigation measure to ensure the Group’s financial position remains sound and that the Group is able to meet its financial 
obligations in the event of low oil prices. 
At 30 June 2024, the Group had 50,000 bbls of crude oil hedged through Brent oil price swaps at a weighted average price of 
US$83.91/bbl.  
Effects of hedge accounting  
The effects of the oil price swaps on the group’s financial position and performance are as follows:

[iii] Interest rate risk
Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes 
in market interest rates. 
The Group has no interest-bearing assets considered to materially expose the Group’s core income and/or operating cash 
flows to changes in market interest rates. 
As at 30 June 2024 and 30 June 2023, the Group’s interest rate risk arises from borrowings, issued at variable rates, exposing 
the Group to cash flow interest rate risk.  Group policy is to manage material interest rate exposure.  Regular sensitivity 
analysis is conducted to evaluate the potential impact of unfavourable interest rate movements on the Group’s future 
financial position.  The results of this evaluation are used to determine the most appropriate risk mitigation tool to be used. 
During the current and prior financial year, the Group did not enter into any interest rate swap contracts. 
The Group manages its cash flow interest rate risk by using floating to fixed interest rate swaps.  Such interest rate swaps 
have the economic effect of converting borrowings from floating to fixed rates.  Under the interest rate swaps, the Group 
agrees with other parties to exchange, at specific intervals, the difference between fixed contract rates and floating-rate 
interest amounts calculated by reference to the agreed notional principal amounts. 
The Group’s exposure to interest rate risk for financial instruments is set out below:

B.
Credit risk 
Credit risk is managed on a Group basis.  Credit risk refers to the risk that a counterparty will default on its contractual 
obligations resulting in financial loss to the Group.  Credit risk arises from cash and cash equivalents, derivative financial 
instruments, as well as credit exposures to customers, including outstanding receivables. 
It is acknowledged that the Group’s sales of crude oil are primarily concentrated with two counterparties.  However, the 
Group has policies in place to ensure that sales of products and services are made to customers with an appropriate credit 
history, and that the Group has the ability to sell crude to other parties if desired. 
Derivative counterparties and cash transactions are limited to high credit quality financial institutions.  Where commercially 
practical the Group seeks to limit the amount of credit exposure to any one financial institution. 
The maximum exposure to credit risk at the end of each reporting period is the carrying amount of the financial assets as 
summarised in this note. 
HORIZON OIL ANNUAL REPORT 2024
87

The credit quality of financial assets that are neither past due nor impaired can be assessed by reference to external credit 
ratings (if available) or to historical information about counterparty default rates.

The Group applies the AASB 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss 
allowance for all trade receivables.  The expected loss rates are based on the payment profiles of sales over a period of 
36 months before 30 June 2024 and the corresponding historical credit losses experienced within this period.  The historical 
rates are adjusted to reflect current and forward-looking information on key factors affecting the ability of the customers to 
settle the receivables.  Management has assessed the collectability of these amounts based on the customer relationships 
and historical payment behaviour and believe that the amounts are still collectable in full. 
On that basis, the loss allowance as at 30 June 2024 was determined as follows for trade receivables: 
AS AT 30 JUNE 2024

MORE THAN 30 DAYS 
DUE PAST 
MORE THAN 60 DAYS

As at 30 June 2024, there were no financial assets that are past due (30 June 2023: US$Nil).  At the date of this report, the 
full balance of the receivables has been received in cash. 
C.
Liquidity risk 
Liquidity risk is the risk that the Group will encounter difficulty in meeting obligations associated with financial liabilities. 
The Group has policies in place to manage liquidity risk by maintaining adequate reserves and by continuously monitoring 
forecast and actual cash flows and matching profiles of financial assets and liabilities. 
Financing arrangements 
As at 30 June 2024 and 30 June 2023, the Group had no undrawn borrowing facilities.

Fair value estimation 
The fair value of financial assets and financial liabilities must be estimated for recognition and measurement or for 
disclosure purposes. 
AASB 7 ‘Financial Instruments: Disclosures’ requires disclosure of fair value measurements by level of the following fair value 
measurement hierarchy: 
(a)
quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1); 
(b)
inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (as 
prices) or indirectly (derived from prices) (level 2); and 
(c)
inputs for the asset or liability that are not based on observable market data (unobservable inputs) (level 3).

There were no transfers between levels 1, 2 or 3 for recurring fair value measurements during the year. 
The Group’s policy is to recognise transfers into and transfers out of fair value hierarchy levels as at the end of the reporting 
period. 
The Group did not measure any financial assets or financial liabilities at fair value on a non-recurring basis as at 
30 June 2024. 
[ii] Valuation techniques used to derive fair values 
The fair value of financial instruments traded in active markets (such as publicly traded derivatives) was based on quoted 
market prices at the end of each reporting period.  The quoted market price used for hedging derivatives held by the Group 
was the current bid price.  These instruments are included in level 1. 
The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is 
determined using valuation techniques.  These valuation techniques maximise the use of observable market data where it 
is available and rely as little as possible on entity specific estimate.  If all significant inputs required to fair value an 
instrument are observable, the instrument is included in level 2. 
The fair value of equity investment as at 30 June 2024 is equivalent to the consideration paid to acquire the 3.5% interest in 
the unlisted shares. As one or more of the significant inputs is not based on observable market data, the instrument is 
included in level 3. 
Specific valuation techniques used to value financial instruments include: 
– Discounted cash flow projections based on reliable estimates of future cash flows.  
All resulting fair value estimates for unlisted equities are included in level 3.  
[iii] Other fair value measurements 
The carrying value of receivables and payables are assumed to approximate their fair values due to their short-term nature. 
The fair value of other financial liabilities (being financial guarantees), after factoring in the likelihood that the parent entity 
would be required to perform under the guarantees, was not considered material. 
The fair value of borrowings for disclosure purposes is not materially different to their carrying value given the likely 
anticipated repayment profile.  Refer to Note 19 for further details.  
The fair value of other classes of financial instruments not yet covered above was determined to approximate their carrying 
value. 
E.
Capital risk 
The consolidated entity manages its capital to ensure that entities in the consolidated group will be able to continue as a 
going concern while maximising the return to stakeholders through the optimisation of the debt and equity balances. 
F.
Climate-related and other emerging risks 
Climate-related and other emerging risks encompass the impact of climate change, any associated climate change 
regulations, funding restrictions and any other emerging factors (e.g. technological disruption to the oil and gas industry) 
that could have a material impact on the Group.  The Group will continue to monitor the impact of these risks.

At the date of this report, the Group is impacted by emissions trading regulations in New Zealand.  Currently there are no 
equivalent emissions trading regulations in the other jurisdictions in which the Group operates.  
The Group manages the impact of the emissions trading regulations in New Zealand by acquiring New Zealand carbon credits 
(NZUs) throughout the financial period to offset its annual obligation, such that it is not wholly exposed to the NZU price at 
the date of settlement.   
At 30 June 2024, if the New Zealand carbon credit price had been 10% p.a. higher or lower and all other variables held 
constant, the net result for the financial year would increase/(decrease) and net assets as at 30 June 2024 would

1 No price is payable by a participant in the Long-Term Incentive Plan on the exercise of a SAR, Performance Rights and Deferred STI Rights.  The ‘strike 
price’ for SARs is the 10-day volume weighted average price for Horizon shares at effective allocation date.  Following shareholder approval of a A$ 1.35 
cent capital return, at an extraordinary general meeting on 7 October 2022, the strike prices of SARs on issue have been reduced by A$ 1.35 cents. 
 
2  In accordance with the plan, the number of 2022 deferred STI rights held by each KMP were adjusted during the financial year for the A$ 1.35 cents capital 
return per share and aggregate A$ 3.15 cent dividend distributions per share. 
 
Long Term Incentive Plan (SARs) 
The LTI arrangements approved at the 2010 annual general meeting apply to senior executives and involve the grant of share 
appreciation rights which may vest subject (amongst other things) to the level of total shareholder return (‘TSR’) achieved in 
the vesting period, relative to an appropriate index.  This plan applied for the financial years up to and including 2022.  As 
noted in the remuneration report, following a review of the current long term incentive plan award of Share Appreciation 
Rights), the Board approved a revised LTI Plan which involves the award of performance rights in place of share appreciation 
rights.  The rationale for the new LTI plan is to create a stronger link between performance and reward and to align the 
interests of Senior Executives more strongly with those of the shareholders of Horizon. 
A SAR is a right to receive either or both a cash payment or shares in the Company, as determined by the board, subject to 
the Company satisfying certain conditions, including performance conditions. 
The LTI Plan provides that the amount of the cash payment or the number of shares in the Company that the participant 
receives on exercise of the SAR is based on the value of the SAR at the time it is exercised (’SAR Value’).  The SAR Value is 
the excess, if any, of the volume weighted average price (’VWAP’) of shares in the Company for the ten-business day period 
up to the date before the date the SAR is exercised over the VWAP of shares in the Company for the ten-business day period 
up to the day before the “Effective Allocation Date” for the SARs.  The Effective Allocation Date for the SARs is the grant date 
of the SARs or any other day determined by the board, at the time of the grant.  The Effective Allocation Date would generally 
be the date the executive’s entitlement was determined. 
If the board determines that the SARs are to be satisfied in cash, the amount of cash that the participant receives on the 
exercise of the SARs is the SAR Value multiplied by the number of SARs exercised (less any deduction for taxes that the 
Company is required to make from the payment).  If the board determines that the SARs are to be satisfied in shares, the 
number of shares that the participant receives on the exercise of the SARs is the SAR Value divided by the volume weighted 
average price of shares in the Company for the ten-business day period up to the day before the day the SARs are exercised.  
Where the number of shares calculated is not a whole number, it will be rounded down to the nearest whole number. 
Long Term Incentive Plan (Performance Rights) 
The LTI arrangements approved at the 2022 annual general meeting apply to senior executives and involve the grant of 
performance rights which may vest subject (amongst other things) the achievement of certain share price hurdles, A$25 
million of cumulative share trades at or above the share price hurdles and the one-month VWAP, at the one year anniversary 
HORIZON OIL ANNUAL REPORT 2024
96

of achieving the share price hurdle, must meet or exceed the share price hurdle.  This plan applied for from and including 
the 2023 financial year. 
Under the LTI Plan, the board has the discretion, subject to the ASX Listing Rule requirements, to grant performance rights 
to executives as long-term incentives.  A performance right is a right to receive shares in the Company, subject to the 
Company satisfying certain conditions, including performance conditions. Each performance right entitles the holder to one 
Horizon Ordinary share should the performance right vest. 
No price is payable by a participant in the Long-Term Incentive Plan on the exercise of a SAR or Performance Right. 
During the financial year, the Horizon Long-Term Incentive Plan and Horizon Employee Option Scheme are also administered 
by the Horizon Employee Share Trust.  This trust is consolidated in accordance with Note 1(C ). 
Shares issued by the trust to the employees are acquired through the issuance of new Ordinary shares by the Company.  
Shares held by the trust and not yet issued to employees at the end of the reporting period are shown as treasury shares in 
the financial statements.  Refer to Note 23(D) for details.

In accordance with the plan, the Share Price Hurdles were adjusted to account for distributions to shareholders during the 2024 financial year. Share price 
hurdles were only adjusted for distributions made prior to the Performance Rights being exercised

The value per Performance Right at grant date is determined by an independent expert. 
3 
No price is payable by a participant in the Long-Term Incentive Plan on the exercise of a Performance Right. 
 
The Group engages external, independent and qualified valuers to determine the fair value at grant date.  The fair value of 
the performance rights is using a Monte Carlo simulation technique.  
The Monte Carlo simulation technique used to calculate the theoretical value of the performance rights uses current stock 
prices, expected dividend yield, expected interest rates, time to expiration and expected volatility.  A calculated share price 
volatility of 55% - 60.0% was applied in the valuations.  All other parameters were based on the specific terms of the share 
appreciation rights issued or observable market data.

Note 34 Contingent asset 
The Group had no contingent assets as at 30 June 2024. 
Note 35 Contingent liabilities 
The Group had contingent liabilities as at 30 June 2024 and 30 June 2023 that may become payable in respect of: 
In accordance with normal oil and gas industry practice, the Group has entered into joint operations and farm-out 
agreements with other parties for the purpose of exploring and developing its petroleum interests.  If a participant to a joint 
operation defaults and fails to contribute its share of joint operation obligations, then the remaining joint operation 
participants are jointly and severally liable to meet the obligations of the defaulting participant.  In this event, the interest in 
the permit or licence held by the defaulting participant may be redistributed to the remaining participants.  In the event of a 
default, a contingent liability exists in respect of expenditure commitments due to be met by the Group in respect of 
defaulting joint operation participants. 
The Group occasionally receives claims arising from its operations in the normal course of business.  In the opinion of the 
directors, all such matters are either covered by insurance or, if not covered, are without merit or are of such a nature the 
amounts involved would not have a material impact on the results. 
No material losses are anticipated in respect of any of the above contingent liabilities. 
Note 36 Events after balance sheet date 
Other than the matters disclosed in this report, there has not been any matter or circumstance which has arisen since 
30 June 2024 that has significantly affected, or may significantly affect:

The financial statements were authorised for issue by the Board of Directors on 28 August 2024.  The Board of Directors has 
the power to amend and reissue the financial statements. 
Note 37
Exploration and development commitments 
The Group has entered into joint operations for the purpose of exploring, developing and producing from certain petroleum 
interests.  To maintain existing interests or rights to earn interests in those joint operations the Group will be expected to 
make contributions to ongoing exploration and development programs.  Since such programs are subject to continual review 
by operating committees, upon which the Group is represented, the extent of future contributions in accordance with these 
arrangements is subject to continual renegotiation. 
Subject to the above-mentioned limitations, the directors have prepared the following disclosure of exploration and 
development expenditure commitments not recognised in the consolidated financial statements.  These are payable as 
follows, based on current status and knowledge of estimated quantum and timing of such commitments by segment.

The above commitments may be deferred or modified with the agreement of the host government, by variations to the terms 
of individual petroleum interests, or extensions to the terms thereof.  Another factor likely to delay timing of these 
commitments is the potential lack of availability of suitable drilling rigs in the area of interest. 
The commitments may also be reduced by the Group entering into farm-out agreements or working interest trades, both of 
which are typical of the normal operating activities of the Group. 
In addition to the above commitments, the Group has invested funds in other petroleum exploration interests, but is not 
exposed to a contingent liability in respect of these, as it may choose to exit such interests at any time at no cost penalty 
other than the loss of the interests.

Information concerning the classification of securities 
A.
Partly paid ordinary shares 
 
Partly paid ordinary shares carry the rights of fully paid ordinary shares and to that extent they have been recognised as 
ordinary share equivalents in the determination of basic earnings per share.  All partly paid shares on issue are held by the 
Company. 
Details regarding the partly paid ordinary shares are set out in Note 22a. 
B.
Performance rights and share appreciation rights granted as compensation 
 
Performance rights and share appreciation rights (SARs) granted to employees under the Long-Term Incentive Plan or 
Employee Option Scheme issued are included in the calculation of diluted earnings per share to the extent to which they are 
dilutive.  The SARs are considered to be contingently issuable shares and are treated as outstanding and included in the 
calculation of diluted earnings per share if the relevant performance hurdles have been met.  Performance Rights and SARs 
have not been included in the determination of basic earnings per share. 
Details regarding the options and share appreciation rights are set out in Note 32.
