20 February 2024 – Mercury progressed its growth ambitions during the period, with the delivery of more renewable

generation underpinning business performance.

“The renewable energy sector is undergoing transformational growth, and we are part of that change. The opportunity ahead of

us is material – Aotearoa New Zealand’s total energy consumption is expected to reach nearly 60% renewable by 2050, well up

from the 20% we’re currently at,” said Mercury’s Chief Executive Vince Hawksworth.

FINANCIAL OVERVIEW

Mercury’s net profit after tax was $174 million for the half year, down $65 million on the prior comparable period due to higher

depreciation, interest charges and net changes in fair value. Mercury reported EBITDAF of $434 million, $17 million down on the

prior comparable period, a strong performance given the much higher hydro generation during HY23.

Earnings for the period were positively influenced by ongoing investment in renewable generation together with higher prices.

Wind generation increased by over 40% to 1,109GWh, with the full contribution of generation from Turitea South and

commissioning of Kaiwera Downs 1 wind farms.

Operational expenditure of $191 million was up $31 million reflecting increases in employee-related expenses and maintenance

expenses mostly from wind contracts.

Stay-in-business capital expenditure for the period was $60 million (up $29 million). Growth capital expenditure was $70 million

(up $26 million) and largely related to construction costs incurred for the addition of a fifth unit at our Ngā Tamariki geothermal

station and completion of the Kaiwera Downs 1 wind farm near Gore. Net debt was $1,983 million, up $76 million primarily due

to higher interest and tax paid combined with a lift in capital expenditure on new generation projects and geothermal drilling.

ENABLING ELECTRIFICATION THROUGH RENEWABLES DELIVERY

Mr Hawksworth said business activity over the period was focused on executing against Mercury’s commitment of up to $1

billion investment over the financial year to generation development over the next three years. Two of the three major projects

previously signalled are expected to meet this timeframe.

“Overall, we’re pleased with progress to date. We committed $220 million in September to build a fifth generating unit at our Ngā

Tamariki geothermal station, which will add another net 46MW. We’re also at the advanced stages of approving the

development of the 155MW Kaiwera Downs 2 wind farm,” he said.

The third signalled project, Kaiwaikawe wind farm, is experiencing delays related to procurement and construction logistics

which will likely delay construction commencement into FY25.


“In addition, we celebrated the opening of our 43MW Kaiwera Downs 1 wind farm in November, completed under budget and on

schedule. This is testament to the capability of our team and contractors together with consistent, transparent engagement with

the community,” said Mr Hawksworth.

Following the period end, Mercury also issued a request for Expressions of Interest for an offtake agreement for 100MW of solar

energy, commencing in 2026.

“We see this as an important step towards further diversification of our renewable energy portfolio, and a meaningful way to

support the role independent generators play in New Zealand’s energy market,” said Mr Hawksworth.

UNLOCKING SYNERGIES FOR CUSTOMER VALUE

In December, the goal of bringing Mercury and Trustpower people, processes and systems together was achieved. This

included migrating all Mercury mass market brand customers onto a single technology stack, a key step towards unlocking

benefits from the acquisition of Trustpower’s retail business in May 2022.

“This gives us a solid platform to deliver greater value for customers in terms of choice, enhanced experience, and the delivery

of new and innovative solutions,” said Mr Hawksworth.

The business remains on track to realise the integration synergies previously forecast, with the majority expected in FY25.

Even with those efficiencies, Mercury will lift electricity prices for most customers effective 1 April 2024 as costs to the retail

business have increased. Mr Hawksworth said that the business would continue to offer targeted measures to support our

customers most in need.

NAVIGATING THE TRANSITION

“Collective action and whole-of-system thinking will be critical to unlocking prosperity through the energy transition for every

individual,’ said incoming Mercury Chair Scott St John.

“Managing affordability will be a key challenge as the transition progresses, and Mercury will continue to work with the sector,

community, Government and others on this,” said Mr St John.

“We continue to have an open conversation about the impact of cumulative changes on affordability, including distribution and

transmission investment, growth in intermittent renewables, New Zealand’s Emissions Trading Scheme and near-term inflation,

skilled worker shortages and supply chain issues,” he said.

“We remain mindful of the role supportive policy will play in accelerating the electrification of New Zealand’s economy in an

inclusive way. We welcome the clarity on Onslow and continue to advocate for clarity on the role of gas, a clear consenting

regime, demand-side policies and network and transmission investment,” he said.

OTHER KEY OPERATIONAL ACTIVITIES

 Contributed to the proposed Sector and Government energy transition framework to enable a system-wide approach to the

transition.

 Experienced delays to the geothermal drilling campaign. The contract with the drilling rig contractor was terminated and we

are currently negotiating an alternative contractor to complete campaign.

 Embedded adaptive ways of working, including changes to organisational structure, to support better performance. Adaptive

leadership and diverse emerging leaders programmes performed strongly.

 Progressed enhanced health, safety and wellbeing programme, with no recordable injuries for the half year (excluding offsite

lost time injuries).

 Welcomed new Chair, Scott St John. Mercury extends its thanks to Prue Flacks for her substantial contribution over the last

13 years, particularly during her last four years as Chair.

INTERIM DIVIDEND

The Board has declared a fully imputed interim dividend of 9.3 cents per share, up almost 7% on the HY23 dividend. Full year

dividend guidance is unchanged at 23.3 cents per share expected to be the 16th consecutive year of ordinary dividend growth.

Mercury’s Dividend Reinvestment Plan continues, with shareholders able to reinvest their dividends into Mercury shares with a

2% discount.

GUIDANCE

FY24 EBITDAF guidance has increased to $880 million from $835 million, mostly due to better pricing outcomes in our

generation and wholesale segment. This assumes mean hydro generation (4,067GWh) and is subject to future hydrological

volatility, wholesale market conditions and any material adverse events, significant one-off expenses or other unforeseeable

circumstances.

Key messages
•Electricity futures three year forward price stable over

HY24, this is partly a result of higher short term prices

offsetting lower mid to long term prices

•Short term futures pricing impacted by hydrology,

generation commissioning delays, peak demand growth,

availability of firming generation and upstream gas

production. Carbon prices lifted after the government

adopted the Climate Change Commission’s advice and

then remained flat throughout the period

•Mid to long term forward prices decline, driven by supply

and demand assumptions as new build generation is

committed to across the sector. This is partially offset by

higher generation development costs and increased

firming requirements. Peak demand growth has been 1.5

- 2% per annum since 2020

This required collaboration with others seeking to create a future

where communities and Aotearoa are thriving — an outcome

which positions Mercury for similar success.

This update is the first with our new Chair, Scott St John.

We extend our thanks to Prue Flacks for her substantial

contribution over the last 13 years, and particularly during her

four-year tenure as Mercury’s Chair. Her exemplary leadership

has helped set us up for our next stage of growth.

CHAIR &

CHIEF EXECUTIVE

U P DAT E .

New Zealand’s renewable energy sector is on a significant

growth trajectory as it looks to meet the electrification

opportunity ahead, and Mercury is committed to supporting

that shift. The scale of the opportunity is material – renewable

electricity is expected to account for nearly 60% of New

Zealand’s energy consumption by 2050, up from about

20% today

1

.

As a result, the first half of the 2024 financial year has been

one of action as we pursue our growth ambitions. We made

substantial headway on our renewable energy and retail

goals, delivering on our purpose: Taking care of tomorrow:

Connecting people and place today; Tiakina te anamata,

mā te tūhono i ngā tāngata me ngā wāhi o te inamata.

FINANCIAL OVERVIEW

Mercury’s net profit after tax was $174 million for the half

year, down $65 million on the prior comparable period due

to higher depreciation, interest charges and net changes

in fair value. Mercury reported EBITDAF

2

of $434 million,

$17 million down on the prior comparable period. This is a

strong performance given the much higher hydro generation

during HY23. Earnings for the current period were positively

influenced by our ongoing investment in renewables together

with higher prices. Wind generation increased to 1,109 GWh

as we continued to deliver on our renewable ambitions, with

the full contribution generation from Turitea South and

commissioning of Kaiwera Downs 1 wind farms.

Operational expenditure of $191 million was up $31 million

reflecting increases in employee related expenses and

maintenance expenses mostly from wind contracts.

Stay-in-business capital expenditure for the period was

$60 million (up $29 million). Growth capital expenditure

was $70 million (up $26 million) and largely related to

construction costs incurred for the addition of a fifth unit

at our Ngā Tamariki geothermal station and completion

of the Kaiwera Downs 1 wind farm near Gore.

Net debt was $1,983 million, up $76 million primarily due

to higher interest and tax paid combined with a lift in

capital expenditure on new generation projects and

geothermal drilling.

FY24 EBITDAF guidance has increased to $880 million

from $835m, mostly due to better pricing outcomes in

our generation and wholesale segment. This assumes

mean hydro generation (4,067GWh) and is subject to

future hydrological volatility, wholesale market conditions

and any material adverse events, significant one-off

expenses or other unforeseeable circumstances.

INTERIM DIVIDEND

The Board has declared a fully imputed interim dividend of 9.3

cents per share, up almost 7% on the HY23 dividend. Full year

dividend guidance is unchanged at 23.3 cents per share expected

to be the 16th consecutive year of ordinary dividend growth.

Our Dividend Reinvestment Plan continues, with shareholders able

to reinvest their dividends into Mercury shares with a 2% discount.

ELECTRIFICATION.

We are pleased to have progressed two of the three major

projects expected in this timeframe.

The first wave of this investment commitment was

announced in September with the decision to build a fifth

generating unit at our Ngā Tamariki geothermal station,

which will boost our generation output by net 46MW

(390 GWh p.a.). Our key supplier on this project, Ormat

Technologies, has been impacted by the situation in Gaza

and we are monitoring this carefully. We are not currently

expecting delivery timeframes to be materially impacted.

Regarding the second wave of this investment commitment,

contractor. We are currently in the process of negotiating an

alternative contractor to complete our drilling campaign and

expect to engage a new provider in the near future.

Following the period end, we were pleased to issue a request

for Expressions of Interest for an offtake agreement for

100MW of solar energy, commencing in 2026. We see this

as an important step towards further diversification of our

renewable energy portfolio, and a meaningful way to support

the role that independent generators play in New Zealand’s

energy market.

A PATHWAY TO GREATER

we are at the advanced stages of approving the development

of Kaiwera Downs 2 wind farm (155MW). The project is

expected to reach Final Investment Decision this financial year.

The third signalled project, Kaiwaikawe wind farm, is

experiencing delays related to procurement and construction

logistics which will likely delay construction commencement

into FY25.

In November we celebrated the opening of the Kaiwera

Downs 1 wind farm (43MW), with the project completing

under budget and on schedule. This is testament to the

capability of our team and contractors together with

consistent, transparent engagement with the surrounding

community. We are mindful of the ongoing role we will play

in this community and continue to focus on engagements

that foster shared value over the long term.

Our geothermal drilling campaign has experienced delays

and we have terminated our contract with the drilling rig

During the period we focused on executing

against our signalled commitment of up

to $1 billion investment over the financial

year to generation development over the

next three years.

DECREASE ON

PRIOR PERIOD

ENABLING

In December we achieved our goal to bring Mercury and Trustpower (people, processes,
systems) together following our acquisition of the Trustpower retail business in May 2022.

This included migrating all Mercury brand mass market

customers onto a single technology stack, a key step

towards unlocking benefits from the acquisition.

This gives us a solid platform on which we can deliver greater

value for customers in terms of choice, enhanced experience,

and the delivery of new and innovative solutions. We now

have a range of energy, broadband and mobile bundled

offers available to all customers, and we have begun

developing ‘smart’ solutions for EV owners and customers

who want greater control over their energy use.

The business remains on track to realise the integration

synergies previously forecast, with the majority expected

in FY25.

Managing affordability will be a key challenge as the energy

transition progresses and we continue to work with the sector,

community, Government and others on this, including with

our partners and suppliers to manage costs. We also continue

to have an open conversation about the impact of cumulative

changes on affordability, including distribution and

transmission investment, growth in intermittent renewables,

New Zealand’s Emissions Trading Scheme and near-term

inflation, skilled worker shortages and supply chain issues.

In addition to participating in these conversations,

we continue to strengthen the support we provide for

customers in hardship recognising the persistent nature of

this challenge, including developing solutions that address

the broader challenges related to affordability. During the

period we completed our joint research into hidden hardship

with Genesis and began progressing solutions which were

co-designed with community groups. We also completed

phase one of a Winter Energy Study in partnership with

Kāinga Ora – Homes and Communities trialling how

capped bills could benefit customers over winter.

We will lift electricity prices for most customers this financial

year. The business will continue to offer targeted measures

to support those most in need.

CLOSING REMARKS

We thank our people and our partners

for what they have helped Mercury

achieve in the first half of the 2024

financial year.

We are focussed on supporting

New Zealand’s electrified, digitalised

future and believe that by enabling

electrification, innovating for customers

and collaborating with others we can

help unlock a thriving future for our

business and New Zealand.

We thank you for your continued

support and look forward to updating

you on further progress at the financial

year end.

Ngā mihi nui ki a koutou katoa.

SCOTT ST JOHN

CHAIR

VINCE HAWKSWORTH

CHIEF EXECUTIVE

Collective action and whole-of-system thinking

will be critical to unlocking the infrastructure

investment needed for prosperity through the

energy transition.

Over the period we contributed to the proposed Sector and

Government energy transition framework. The group is now

actively seeking to partner with the Government on the framework

to enable the system-wide approach this mechanism supports.

We also continued to participate in other cross-sector forums

to help us address shared obstacles to the delivery of renewables

at pace, including supply chain and workforce issues.

We remain mindful of the role that supportive policy will play

in accelerating the electrification of New Zealand’s economy

in an inclusive way. We welcome the clarity provided on Onslow

and continue to advocate for: clarity on the role of gas to ensure

security of supply; a clear consenting regime to enable renewable

development at pace while maintaining social licence; demand-

side policies that support electrification for households, businesses

and large-scale initiatives; and network and transmission

investment that supports a smart electricity system.

BUILDINGCAPABILITY


& PRODUCTIVITY.

As the scale of the opportunity that

electrification presents continues to grow,

our people and the ways we work become

increasingly important to our ability to

drive value.

During the period we further embedded adaptive ways of

working into our organisation, fostering more dynamic decision

making in the face of change. We have taken lessons from our

retail integration programme and are applying these to other

parts of the business.

We also made changes to our organisational structure to

support better performance. This includes converging around

three core business units, supported by three enabling units.

Our focus on growing talent also continued, with our adaptive

leadership and diverse emerging leaders programmes both

performing strongly.

Finally, we are well progressed in rolling out our enhanced

health, safety and wellbeing programme across the business,

building a stronger culture of safety. There have been no

recordable injuries for the half year (excluding offsite lost time

injuries), while the 12-month rolling TRIFR (Total Recordable

Injury Frequency Rate) was 0.21, significantly down on TRIFR

for the prior two years.

However, we are not complacent and acknowledge that it is

important that we continue to reflect on previous incidents.

In December, after careful consideration Mercury made the

decision to plead not guilty to two WorkSafe charges related

to the Rotokawa steam hammer incident from July 2021

and we continue to work through this process.

Based on our review, nothing has come to

our attention that causes us to believe that

the consolidated interim financial statements

of the Group do not present fairly, in all material

respects, the consolidated financial position

of the Group as at 31 December 2023, and its

consolidated financial performance and cash

flows for the six months ended on that date,

in accordance with New Zealand Equivalent to

International Accounting Standard 34:

(“the Group”). The Group financial statements comprise

Mercury NZ Limited ("the Company") as the parent, and

its subsidiaries, including its investments in associates

and interests in joint arrangements.

The Company is incorporated in New Zealand and

registered under the Companies Act 1993. It is listed on

the NZX Main Board and on the ASX, with foreign exempt

listed status. It also has bonds quoted on the NZX debt

market. Mercury NZ Limited is an FMC reporting entity

under the Financial Markets Conduct Act 2013.

The Company is a mixed ownership model company, majority

owned by the Government, bound by the requirements of the

Public Finance Act 1989. The liabilities of the Group are

not guaranteed in any way by the Government or by any

other shareholder.

Basis of preparation.

The unaudited Group financial statements have

been prepared:

- in accordance with the Financial Markets Conduct

Act 2013, Generally Accepted Accounting Practice in

New Zealand (“GAAP”), the New Zealand Equivalent to

International Accounting Standard 34

Interim Financial

Reporting

and International Accounting Standard 34

Interim Financial Reporting.

- on a historical cost basis, with the exception of certain

fair value measurements.

- using the same accounting policies for all reporting

periods presented, with the exception of a change in the

accounting treatment of unhedged electricity derivatives

and FTRs (see Significant Matters).

- in millions of New Zealand dollars, unless otherwise stated.

- exclusive of GST, with the exception of payables and

receivables that include GST invoiced.

These Group financial statements, including the accounting

policies adopted, do not include all the information and

disclosures required in the annual financial statements.

Beyond those disclosed below, the Group financial statements

have been prepared using the same accounting policies as,

and should be read in conjunction with, the Group’s annual

financial statements for the year ended 30 June 2023.

Estimates and judgements.

The preparation of financial statements requires judgements

and estimates that impact the application of policies and

the reported amounts of assets and liabilities, income and

expenses. Actual results may differ from these estimates.

The areas of significant estimates and judgements are

as follows:

- Fair value of generation plant and equipment

(refer note B1).

- Valuation of financial instruments (refer note E1).

SIGNIFICANT MATTERS.

Change in accounting treatment of unhedged

electricity derivatives.

Consistent with the Group’s 2023 annual financial statements,

realised gains and losses (settlements) on unhedged derivative

contracts for the half year are not reclassified to revenue or

expenses and continue to be recognised within the change

in fair value of financial instruments in the Consolidated

Income Statement. Settlements of unhedged derivatives

that occurred in the comparative half year period have not

been reclassified or restated in the financial statements as

the overall impact is not considered material.

Restatement on presentation of Financial Transmission

Rights (FTRs).

Consistent with the Group’s 2023 annual financial statements,

the presentation of FTRs on the Consolidated Balance Sheet

has changed to correctly reflect net settlement. Effects

of this change in presentation on the 31 December 2022

comparative Consolidated Balance Sheet are shown in

the following table:

CONSOLIDATED BALANCE SHEET.

A. FINANCIAL PERFORMANCE

NOTE A1. REVENUE

Mercury earns revenue from the following sources:

Electricity generation

Revenue is received from electricity generated and

sold through the wholesale markets and physical power

purchase agreements (PPAs). Revenue is recognised

at the time of generation and at the spot market or

contractual price.

Electricity and gas sales to customers

Electricity and gas sales to customers are recognised when

the energy is supplied for customer consumption.

Acquisition incentives such as credits and appliances

are offered to new customers and treated as individual

performance obligations and a portion of the expected

revenue over the life of the total contract is allocated to the

performance obligation based on their standalone selling

price and recognised immediately. Corresponding contract

assets are recognised on the balance sheet and amortised

to the income statement over the contract period as the

future consideration is billed. Incremental costs to obtain

and retain customers are recognised on the balance sheet

as contract costs and amortised to the income statement

on a straight-line basis over the expected average mass

market customer tenure.

Telco revenue

Customers consume mobile and broadband services which

are measured and billed according to monthly billing cycles

and are recognised when the service has been provided.

Acquisition incentives are treated the same as above.

Other Revenue

Revenue is received from:

- Insurance proceeds and external management

management fees. Revenue is recognised at the time

the insurance proceeds are received and the services

have been delivered.

- Sale of emission units sold to third parties. Gain on sale

is recognised at the point in time that the emission unit

is confirmed as being transferred into the acquirer’s

emission unit account.

Accounting standards, interpretations and amendments not yet effective.

There are no other accounting standards that are not yet effective that will have a material impact on the Group’s

financial statements.

Restatement of a PPA Valuation

An error has been identified in the prior period valuations of a power purchase agreement (PPA) that was acquired in

August 2021 as part of the acquisition of Tilt New Zealand assets.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS.

For the six months ended 31 December 2023

A. FINANCIAL PERFORMANCE

NOTE A2. SEGMENT REPORTING

Identification of reportable segments

The operating segments are identified by management

based on the nature of the products and services provided.

Discrete financial information about each of these operating

segments is reported to the Chief Executive, being the chief

operating decision-maker, on a monthly basis, who assesses

the performance of the operating segments on a measure

of EBITDAF. EBITDAF is a non-GAAP measure that is used

internally to assess the operating performance of the Group

without the impact of non-cash and one-off or infrequent

transactions. Segment EBITDAF represents earnings before

net interest expense, tax expense, depreciation, amortisation,

unrealised change in the fair value of financial instruments,

gain/(loss) on disposal and impairments by each segment

inclusive of an allocation of central operating revenue and

costs. Operating segments are aggregated into reportable

segments only if they share similar economic characteristics.

Realised gains or losses (settlements) on unhedged electricity

swaps are reported within electricity margin for the purposes

of EBITDAF, but are reported within the change in fair value

of financial instruments in the income statement. Realised

gains or losses (settlements) on hedged electricity swaps

are reported within electricity margin for the purposes of

EBITDAF, and within revenue or expenses as appropriate

in the Consolidated Income Statement. Unrealised gains

or losses, on both hedged and unhedged electricity

swaps are not included in EBITDAF and are reported

in either change in fair value of financial instruments in

the income statement or in other comprehensive income.

A reconciliation of EBITDAF to profit before tax can be

found in the summary table of the note.

Identified segments

Generation/Wholesale

The generation/wholesale market segment encompasses

activity associated with the electricity production, electricity

trading, generation development activities and the company’s

share of associates earnings in TPC Holdings Limited (see

note D1). It also includes revenue from the sale of electricity,

to both commercial & industrial customers and the retail

segment, net settlement of energy hedges and sale of

trading emissions units to third parties.

Retail

The retail market segment encompasses activity

associated with sale of electricity, gas, telecommunication

products/services and other related products and services

to mass market customers in New Zealand.

Other

Represents corporate support services which are not

directly attributable to the generation/wholesale or retail

segments and the company’s share of associates earnings

in EnergySource LLC and EnergySource Minerals LLC.

Inter-segment

Transactions between segments represent transfer

charges by generation/wholesale to retail for the

purchase of electricity.

Changes in presentation

The segment note presentation has been updated in both

the current and comparative periods to align with current

management reporting. Notable changes are (a) the

separation of derivatives from generation revenue and (b) the

condensed reporting of electricity revenue, costs and margin.

Intangible assets consist of software, acquired intangible assets (NOW customer list), rights (mainly land access rights), and carbon units held for

settling emissions obligations. All intangible assets are deemed to have a finite useful life.


ASSETS CARRYING VALUES

All assets, except generation plant and equipment, are

recognised at cost less accumulated depreciation. Fixed

assets, excluding land, are depreciated on a straight line

basis over their expected useful lives.

Generation plant and equipment is originally recognised at cost

and subsequently measured at fair value less accumulated

depreciation. An independent valuation is completed annually

to determine the fair value of these assets.

Assets carried at fair value

All generation assets shown at valuation were revalued using

a net present value methodology by PricewaterhouseCoopers,

an independent valuer, as at 30 June 2023.

AREA OF KEY JUDGEMENT

Generation asset valuation

The key assumptions used in the valuation include

the forecast of the future wholesale electricity price path,

generation volumes, projected operational and capital

expenditure and asset life assumptions and discount rates.

In all cases there is an element of judgement required as

valuations make use of unobservable inputs. The valuation

also assumes the on-going operation of New Zealand

Aluminium Smelter Limited at Tiwai Point, no material

changes to the wholesale market regulatory regime, hydro

and geothermal fuel supply being sustained over the

modelled horizon and no material changes to generation

consent conditions.

Generation assets are classified as level three in the fair value

hierarchy due to the use of non-market observable inputs

in the valuation. Keeping all other valuation inputs constant,

the valuation is most sensitive to future wholesale electricity

price path and discount rate. A review of the key inputs used

in the valuation of generation assets as at 30 June 2023,

indicates that there has been no material change in the fair

value of the generation assets as at 31 December 2023.

NOTE C4. COMMITMENTS AND CONTINGENCIES

Contingencies

On 7 June 2021, the Kawerau geothermal power station experienced

an unplanned outage as a result of a mechanical failure. An outage

was completed in June 2023 to install replacement equipment.

The Group received an initial payment of $26m recorded as income

in 2022, and expects to receive additional insurance proceeds in

second half of the 2024 financial year once the total loss to the

Group as a result of the incident has been confirmed. It is not

currently practical to estimate the value of additional insurance

receipts, therefore no additional revenue is recognised.

The Group holds land and has interests in fresh water and

geothermal resources that are subject to claims that have been

brought against the Crown. The Group discloses these claims

as contingent liabilities as the value, timing and likelihood of

the claims being successful are all uncertain.

The Pouakani Claims Trust No 2 and a group of kaumatua have

filed a claim in the Māori Land Court seeking a declaration that

certain parts of the Waikato riverbed on which Mercury operates

hydro assets are Māori customary land, including the riverbed

beneath the Whakamaru, Maraetai I and II and Waipapa dams

and certain related powerstations. The claim has been amended

to include interests in the water flowing over the riverbed. Mercury

holds the fee simple or beneficial title to those parts of Waikato

riverbed beneath the Whakamaru, Maraetai I and II and Waipapa

dams, and has received advice that if the outcome of the claim

adversely affects the Group’s title to, or ability to access or

operate its hydro assets, Mercury may bring a claim seeking

compensation against the Crown. The claim is currently subject

to a judicial review challenge to the Māori Land Court’s decision

to decline Mercury’s application to strike out parts of the claim.

Mercury’s judicial review was partially successful in the High Court.

The High Court decision has been appealed by the applicants,

the Crown and Mercury. The applicants have also filed a related

claim in the Waitangi Tribunal pursuant to the Treaty of Waitangi

Acy 1975, but have not yet taken any further steps in relation to

that claim.

The Group holds land at Maraetai, Waikato that was subject

to a remedies hearing brought against the Government in

the Waitangi Tribunal. The remedies hearing related to an

application seeking binding recommendations for the

resumption of land at Pouakani, including the Group’s land

at Maraetai. The Crown and Ngāti Kahungunu ki Wairarapa

Tāmaki nui-ā-Rua Settlement Trust signed a settlement

deed addressing the resumption claim, and settlement

legislation has now been enacted to bring this claim to an

end. Wairarapa Moana Incorporation has issued a further

claim against the Crown claiming the Ngāti Kahungunu ki

Wairarapa Tāmaki nui-ā-Rua settlement breaches the

New Zealand Bill of Rights Act 1990. Mercury is not a party

to this claim. Mercury has received advice that if a resumption

claim succeeded, Mercury would have rights of recourse

against the Crown for compensation as if the property had

been taken under the Public Works Act 1981.

A separate claim by the New Zealand Māori Council relating

to fresh water and geothermal resources was lodged in 2012

with the Waitangi Tribunal. The Tribunal concluded that Māori

have residual (but as yet undefined) proprietary rights in fresh

water and geothermal resources and it will be for the

Government to determine how any such rights and interests

may best be addressed. The Tribunal has recently indicated

it intends to hear stage three of that inquiry in 2024, and the

inquiry is currently at the interlocutory (pre-hearing) phase.

The impact of this claim on the Group’s operations,

and consequently the amount of any claim or recourse

the Group may have should that impact be adverse to

the Group’s interests, are unknown at this time.

From time to time the Group will issue letters of credit and

guarantees to various suppliers in the normal course of

business. However, there is no expectation that any outflow

of resource relating to these letters of credit or guarantees

will be required.

The Group has no other material contingent assets or liabilities.

Capital commitments

Capital commitments include purchases of both property, plant and equipment (PP&E) and intangibles. PP&E commitments

include contracts for refurbishment of hydro generation assets at Karāpiro, contracts for construction of an addditonal

geothermal OEC unit at Ngā Tamariki and geothermal drilling campaigns across the Kawerau, Ngā Tamariki and Rotokawa

fields. Intangible commitments are contracts to purchase New Zealand emissions trading scheme (NZ ETS) units.

In the event the NZ ETS is terminated the existing purchase agreements, which cover the four year period from the end

of the reporting period, will also terminate.

Operating commitments

As part of its day-to-day operations, the Group from time to time enters various operating arrangements and commitments

with third parties to support and enhance the Group’s long-term licence to operate, provide access to land, and use of natural

resources. These operating arrangements may be short-, medium-, or long-term in nature.

E. RISK

NOTE E1. DERIVATIVE FINANCIAL INSTRUMENTS

The Group uses a range of derivative contracts in order to

manage risk and hedge against cash flow and fair value

volatility. It is the Group’s policy to apply hedge accounting

to reduce volatility in profit or loss, and where possible,

derivatives are designated into hedging relationships under

NZ IFRS 9 as either cash flow or fair value hedges.

Interest rate and cross currency interest rate derivatives

Interest rate swaps and cross currency derivatives are used

to manage interest rate risks. Interest rate swaps where we

pay-fixed, and receive-floating interest rates are designated

as cash flow hedges in a relationship with a portion of

floating rate debt exposure. Interest rate swaps where we

receive-fixed, pay-floating interest rate are designated as fair

value hedges in a relationship with the swap rate on fixed

rate bonds. Cross currency swaps are designated as both

fair value and cash flow hedge relationships with the USPP

and Australian denominated Green wholesale bond (refer

note C2) depending on the component of the debt being

hedged: the risk free (swap) rate as a fair value hedge; and

the credit margin as cash flow hedge.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS.

For the six months ended 31 December 2023

Valuation of level 1 financial instruments

Level 1 financial derivatives includes ASX futures and financial transmission rights with fair values determined using quoted

prices. These prices represent regularly occurring market transactions on an orderly basis.

Valuation of level 2 financial instruments

The fair values of Level 2 derivatives are determined using discounted cash flow models. Listed below are the Level 2

derivatives and the key inputs to the valuation model.

Valuation of level 3 financial instruments

The Group uses various methods in estimating the fair value of a financial instrument. Where the fair value of a derivative

is calculated as the present value of the estimated future cash flows of the instrument there are two key inputs being used:

The wide range in discount factors are driven by entering into longer term derivative contracts. Forward electricity spot

prices in the front end of the curve in HY23 were higher, driven by futures price, thus resulting in a higher maximum

price of $214/MWh in HY23 compared to $188/MWh in HY24.

The selection of valuation inputs requires significant judgement, and therefore there is a range of reasonably possible

assumptions in respect of these inputs that could be used in estimating the fair values of these derivatives. Maximum

use is made of observable market data when selecting inputs and developing assumptions for the valuation technique.

Reconciliation of level 3 unrealised fair value movements

The unrealised Level 3 fair value movements in the Group’s Consolidated Income Statement are recognised within ‘change in

the fair value of financial instruments’, along with realised gains/losses on financial instruments not in a hedging relationship.

Sensitivity of level 3 fair value measurements

The Group uses unobservable inputs to measure the fair value of Level 3 electricity derivatives. These inputs are most sensitive

to changes in electricity forward prices. These electricity price derivatives are in a net asset position on the balance sheet.

The Group has a net exposure that if there was an increase in the forward price would likely result in an increase in fair value

of the Consolidated Balance Sheet, and a decrease in the forward price would likely result in a decrease in fair value.

F. OTHER

NOTE F1. SUBSEQUENT EVENTS AND OTHER MATTERS

The Board of Directors has approved a fully imputed interim dividend of 9.3 cents per share to be paid on 2 April 2024.

The Group plans to continue with the DRP announced in FY2022, with a DRP strike price to be determined by the

average of daily volume weighted average sale price for a share, calculated on all price setting trades of shares that

took place through the NZX Main Board over a period of five trading days starting on 18 March 2024, less a 2% discount.

There are no other material events subsequent to balance date that would affect the fair presentation of these

financial statements.

Deferred ‘inception’ gains/(losses) on level 3 derivatives

There is a presumption that when derivative contracts are entered into at an arm’s length basis that the fair value at inception

is zero. The contract price of non exchange traded electricity derivative contracts are agreed on a bilateral basis, the pricing for

which may differ from the prevailing derived market price curve for a variety of reasons. In these circumstances an inception

adjustment is made to bring the initial fair value of the contract to zero at inception. This inception adjustment is amortised

over the life of the contract by adjusting the future price path used to determine the fair value of the derivatives by a constant

amount to return the initial fair value to zero.

and liabilities as at 31 December 2023:
