Financial performance

Contact Energy has reported net profit of $153m in 1H24 and operating earnings (EBITDAF)

of $354m. Reported figures include a net provision release relating to the Ahuroa Gas

Storage facility (AGS) onerous contract of $29m within EBITDAF ($19m within net profit after

tax and interest). Excluding the provision release, underlying net profit was up 70% on 1H23

to $134m and EBITDAF was up 26% to $325m.

The improved operating result was driven by closer alignment of channel pricing to the

wholesale market and greater thermal efficiency, partially offset by lower hydro generation,

reduced steam revenue following the closure of Te Rapa and one-off write-offs of $8m

relating to damage to Peaker assets and the CRM system upgrade programme not

continuing as originally planned.

Hydro volatility characterised operating conditions throughout the period, with flow-on

impacts to wholesale pricing from more thermal generation. Contact increased contracted

sales volumes in anticipation of Tauhara coming online in 4Q 2023 and with the delay to 3Q

2024 applied some mitigations to meet this position. At the same time, Contact has executed

well on its channel mix and pricing strategies.

“The result has been a demonstration of strength in our underlying performance, setting us

up well for the year ahead and we now expect to deliver underlying EBITDAF of $620m in

FY24,” says Chief Executive Mike Fuge.

Operating free cash flow of $187m was up 163% on the prior year on the improved

operating result, relatively lower levels of working capital due to higher thermal generation

and lower tax paid on FY23 profit, partially offset by accelerated stay in business capex. The

Board declared an interim dividend of 14 cents per share, in line with 1H23.

Demand

Negotiations with Rio Tinto have been constructive and have re-enforced Contact’s long-

held view that the New Zealand Aluminium Smelter (NZAS) appears likely to stay. Contact is

expecting a new agreement to be long-term, at a fair price materially above the current

pricing, and including demand response (mitigating dry-year risk).

“A new long-term agreement would de-risk investment in new renewable generation,

contribute to energy security and help to preserve an important export industry, supporting

growth and decarbonisation of the New Zealand economy,” said Mr Fuge.

Renewable development

Remediation works got underway at Contact’s Tauhara geothermal development in

November and re-construction of the steam separation plant is near complete. Tauhara is

expected to come online in Q3 2024 at the initial design capacity of around 152MW

(expecting 174MW from the first planned outage in 2025), and Te Huka 3 is on track to

follow in Q4 2024

iv

.

“I’m extremely proud of the team that has worked hard over the summer to get Tauhara back

into the full swing of commissioning. Both Tauhara and Te Huka will join Contact’s

renewable generation fleet in 2024 and will add 1.9TWh per annum of baseload renewable

output once full capacity is reached.”

Drilling, advanced steamfield design and tendering have progressed to prepare for a final

investment decision in 2024 on GeoFuture, the replacement of Contact’s 65-year-old

Wairākei geothermal plant. Final investment decisions are also expected in 2024 on a

100MW North Island battery and the Kōwhai Park solar development.

“These investments in new renewable technologies will contribute to security of supply as

New Zealand decarbonises, said Mr Fuge”.

Decarbonising the portfolio

Emissions intensity from thermal generation was down ~30% on 1H23 driven largely by the

closure of Te Rapa on 30 June 2023. Portfolio decarbonisation is just one aspect of

Contact’s broader commitment to sustainability, which in December saw Contact win both

the Sustainability Leadership award in the Deloitte Top 200 and move into the number one

ranking of participating New Zealand companies in the DJSI Asia Pacific.

Contact expects to decommission its combined cycle gas generation plant (TCC) at the end

of 2024. A planned outage at TCC was brought forward and completed in December with

additional operating hours approved. Contact has also worked to accelerate the return of its

spare peaker engine and is expecting GT22 to be in service for winter 2024.

Retail

Retail electricity net price has improved in light of rising energy and pass-through costs.

Total connections were up 20,000 on 1H23, driven primarily by broadband. Contact also

expanded its telecommunication offering with the introduction of Contact Mobile and boosted

its time of use offerings with the introduction of Good Weekends. Contact remains focused

on supporting our customers in energy hardship through ERANZ, with offerings like

ConnectMe and EnergyMate, and directly with community groups like Women’s Refuge and

Good Shepherd. Over the last twelve months Contact has provided in excess of one million

dollars to directly support customers in energy hardship.

Outlook

Looking ahead, Mr Fuge said the next six months will see Contact reaching significant

milestones in the delivery of its strategy to lead the decarbonisation of New Zealand.

“We are excited about the future. We have a clear strategy, strong balance sheet with

supportive shareholders and stand ready to deliver on the opportunities in front of us to lead

the decarbonisation of the New Zealand economy over the next decade.”

i

The onerous contract provision for AGS is assessed every 6 months in line with NZ IAS 37. In 1H24 there has been a net provision release

resulting in impacts of $29m EBITDAF and $19m profit. Underlying performance excludes these impacts. All variances and commentary reflect

movements in underlying performance.


ii

Refer to slide 38 of the 2024 interim results presentation for a definition and reconciliation between statutory profit and the non-GAAP profit

measure earnings before net interest expense, tax, depreciation, amortisation, change in fair value of financial instruments (EBITDAF). Contact

has made reclassifications to better align with IFRIC guidance on IFRS 9 resulting in realised gains/losses from market derivatives not in a hedge

relationship (includes market making activity) no longer being reported in operating income (EBITDAF). 1H23 figures restated accordingly.


iii

Refer to Note A3 of the interim financial statements for a definition and reconciliation between cash flow from operating activities and the non-

GAAP measure operating free cash flow. Operating free cash flow represents cash available to repay debt, to fund distributions to shareholders

and growth capital expenditure.

A. Our performance

Notes to the interim financial statements for the six months ended 31 December 2023

A1. SEGMENTS

Contact reports activities under the Wholesale segment and the Retail segment. There have been no significant changes to

Contact’s operating segments in the current period.

The Wholesale segment includes revenue from the sale of electricity to the wholesale electricity market, to Commercial & Industrial

(C&I) customers, and to the Retail segment, less the cost to generate and/or purchase the electricity and costs to serve and

distribute electricity to C&I customers.

The results of Simply Energy Limited and Western Energy Services Limited are included in the Wholesale segment. The results of

Contact Energy Risk Limited have been allocated across the operating segments based on fixed asset values, revenues, and

headcount.

The Retail segment includes revenue from delivering electricity, natural gas, broadband, mobile and other products and services to

mass market customers less the cost of purchasing those products and services, and the cost to serve and distribute electricity to

customers.

‘Unallocated’ includes corporate functions not directly allocated to the operating segments.

The Retail segment purchases electricity from the Wholesale segment at a fixed price in a manner similar to transactions with third

parties.

A2. EARNINGS

The table below provides a breakdown of Contact’s revenue, expenses and earnings before interest, tax, depreciation and amortisation and changes in fair value of financial instruments (EBITDAF) by segment, and a reconciliation from EBITDAF to profit/(loss) reported under NZ GAAP.

EBITDAF is used to monitor performance and is a non-GAAP profit measure. Change in fair value of financial instruments in the Statement of Comprehensive Income includes both ‘realised gains/(losses) on risk management derivatives not in a hedge relationship’ and, 'change in fair value

of financial instruments’ from the table below.

A5. AGS ONEROUS CONTRACT PROVISION

In FY23, Contact recognised an onerous contract provision relating to the Ahuroa Gas Storage (AGS) contract as the value of the

contract is expected to be less than total contract payments. Contact continues ongoing discussions with Flexgas in relation to the

capacity and operations of the AGS facility.

Contact has reassessed the provision to be $90 million at 31 December 2023. Below table shows the movement of the provision

during the period.

Closing balance 90 120 116

There is a significant level of judgement involved in estimating the value Contact will obtain from access to AGS storage for the

remainder of the contract term. Key drivers include the total storage capacity of AGS, Contact’s gas storage requirements,

hydrology, future gas and carbon prices, the level of Contact’s contracted sales, and the market supply/demand balance. There is

interrelation between these assumptions. Any changes in one of these assumptions would not occur in isolation and would drive

other changes which could also impact the estimated value.

The useful economic life of the Stratford Peaker assets have been reduced for accounting purposes following a review of expected

future availability as a result of recent unexpected outages. This has been applied as a change in accounting estimate from 1 July

2023, and results in a $9 million increase to depreciation in the six months ended 31 December 2023.

Contact is in the process of assessing any impact of the Tauhara delay on costs capitalised to the project. Contact will assess the

enduring economic benefit of all such costs prior to finalisation of the FY24 annual financial statements. Any impact would be

immaterial in the context of the cost of the Tauhara project.

Included within property, plant and equipment is $51 million (31 December 2022: $30 million, 30 June 2023: $53 million) of lease

assets with a depreciation charge of $3 million for the six months ended 31 December 2023 (31 December 2022: $2 million, 30

June 2023: $4 million).

Included within additions is capitalised interest of $35 million (31 December 2022: $17 million, 30 June 2023: $44 million) in

relation to, Tauhara, Te Huka Unit 3, and GeoFuture power stations and associated steamfields.

To the shareholders of Contact Energy Limited

Report on the review interim financial statements

11



Conclusion

We have reviewed the interim financial statements of Contact

Energy Limited (the “Company”) and its subsidiaries (together

“the Group”) on pages 2 to 17 which comprise the consolidated

statement of financial position as at 31 December 2023, and the

consolidated statement of comprehensive income, consolidated

statement of changes in equity and consolidated statement of

cash flows for the six month period ended on that date, and a

summary of significant accounting policies and other explanatory

information. Based on our review, nothing has come to our

attention that causes us to believe that the accompanying interim

financial statements on pages 2 to 17 of the Group do not present

fairly, in all material respects, the financial position of the Group

as at 31 December 2023, and its financial performance and its

cash flows for the six month period ended on that date, in

accordance with New Zealand Equivalent to International

Accounting Standard 34: Interim Financial Reporting.

This report is made solely to the Company’s shareholders, as a

body. Our review has been undertaken so that we might state to

the Company’s shareholders those matters we are required to

state to them in a review report and for no other purpose. To the

fullest extent permitted by law, we do not accept or assume

responsibility to anyone other than the Company and the

Company’s shareholders as a body, for our review procedures, for

this report, or for the conclusion we have formed.

Basis for conclusion

We conducted our review in accordance with NZ SRE 2410

(Revised) Review of Financial Statements Performed by the

Independent Auditor of the Entity. Our responsibilities are further

described in the Auditor’s responsibilities for the review of the

financial statements section of our report. We are independent of

the Group in accordance with the relevant ethical requirements in

New Zealand relating to the audit of the annual financial

statements, and we have fulfilled our other ethical responsibilities

in accordance with these ethical requirements.

Ernst & Young provides services to the Group in relation to

trustee reporting, market remuneration surveys and other

assurance services relating to the Company’s Global Reporting

Initiative disclosures, greenhouse gas emissions reporting and

Green Borrowings Programme reporting. Partners and employees

of our firm may deal with the Group on normal terms within the

ordinary course of trading activities of the business of the Group.

We have no other relationship with, or interest in, the Group.




Directors’ responsibility for the interim financial

statements

The directors are responsible, on behalf of the Company, for the

preparation and fair presentation of the interim financial statements

in accordance with New Zealand Equivalent to International

Accounting Standard 34: Interim Financial Reporting and for such

internal control as the directors determine is necessary to enable

the preparation and fair presentation of the interim financial

statements that are free from material misstatement, whether due

to fraud or error.

Auditor’s responsibilities for the review of the interim

financial statements

Our responsibility is to express a conclusion on the interim financial

statements based on our review. NZ SRE 2410 (Revised) requires us

to conclude whether anything has come to our attention that causes

us to believe that the interim financial statements, taken as a whole,

are not prepared in all material respects, in accordance with New

Zealand Equivalent to International Accounting Standard 34: Interim

Financial Reporting.

A review of interim financial statements in accordance with NZ SRE

2410 (Revised) is a limited assurance engagement. We perform

procedures, consisting of making enquiries, primarily of persons

responsible for financial and accounting matters, and applying

analytical and other review procedures. The procedures performed

in a review are substantially less than those performed in an audit

conducted in accordance with International Standards on Auditing

(New Zealand) and consequently do not enable us to obtain

assurance that we would become aware of all significant matters

that might be identified in an audit. Accordingly, we do not express

an audit opinion on those interim financial statements.

The engagement partner on the review resulting in this independent

auditor’s review report is Grant Taylor.

The onerous contract provision for AGS is assessed every 6 months in line with NZ

IAS 37. In 1H24 there has been a net provision release resulting in impacts of $29m

EBITDAF and $19m profit after tax and interest. Underlying performance excludes

these impacts. All variances and commentary reflect movements in underlying

performance.

A return to hydro volatility categorised the operating

conditions in 1H24. The market observed:

•High inflows and soft wholesale spot prices

through July and August.

•Higher spot wholesale pricing as inflows reduced,

particularly in the second quarter.

•Higher thermal generation compared to 1H23,

which had highest inflows in post-market history.

Summary of key financial performance measures

Underlying performance strength

•High contracted sales volumes in

anticipation of Tauhara coming online and a

strong starting fuel position.

•Thermal generation and some acquired

generation required to meet sales position.

•Mitigations in place for the impacts of

Tauhara delay.

•Channel pricing aligned closer to the

wholesale market.

Market

2

Refer to slide 38 for a definition and reconciliation of EBITDAF. Contact has made

reclassifications to better align with IFRIC guidance on IFRS 9 resulting in realised gains/losses

from market derivatives not in a hedge relationship (includes market making activity) no longer

being reported in operating income (EBITDAF). 1H23 figures restated accordingly.

Refer to slide 23 for a reconciliation of

operating free cash flow.

Includes capitalised interest.

As indicated in November 2022, updated

for inflation.

Focus on delivering geothermal developments and supporting security of supply

1H24

•Lines cost increases from 1 April 2024.

•Disappointing results from Maui drilling campaign

factoring into expected future gas availability.

•Pricing volatility increasing, particularly in peak

periods, as intermittent generation comes online.

•Rising thermal fixed costs at ageing thermal plants

will need to be recovered over less generation and

will factor into risk management pricing.

•Increases to wind costs appear to be structural.

•Conditions support a view of long-term wholesale

prices of at least $110-120/MWh (2024 real).

5

Medium term

•TCC outage brought forward and completed

in December 2023. Expect to

decommission TCC at end of 2024.

•Expect Peaker GT22 to return to service

before winter 2024.

•Commissioning of Tauhara and Te Huka

geothermal plants in Q3 and Q4 of 2024 will

add 1.9TWh of new renewable output to the

portfolio annually once at full capacity.

•Recognising a net $29 million provision

release within EBITDAF for Ahuroa Gas

Storage facility (AGS) onerous contract.

De-risking investment in new renewable generation, contributing to energy security and supporting

growth and decarbonisation of the New Zealand economy

A new long-term deal for NZAS would

support the decarbonisation of New Zealand

✓Constructive negotiations with Rio Tinto have re-

enforced Contact’s long-held view that NZAS

appears likely to stay.

✓Contact expects a new agreement to:

▪Be long-term;

▪At a fair price, materially above the current

pricing; and

▪Include demand response (dry-year risk

mitigation).

✓Would create market certainty, de-risking investment

in new renewable generation.

✓Having a large-scale demand response participant

would contribute to dry-year risk mitigation in a

decarbonising market.

Negotiations progressing

Anticipated sector outcomes

Contact has been expecting NZAS to continue operations at Tiwai Point and has been managing its portfolio with that outcome in sight.

The smelter is valuable to New Zealand as a major exporter and its continued operation would contribute to economic growth.

It is highly carbon efficient in its production of premium aluminium, and a major employer and contributor to the Southland economy.

▪Bilateral electricity supply negotiations.

▪Multiple stakeholders with a range of interests.

▪Any agreement can be expected to be conditional on

third-parties.

Hydro generation was down

11% on 1H23, largely due to

1H23 being an unusually wet

period with nationwide inflows

at the 96th percentile of historic.

1H24 saw a return to hydro

volatility and a reduction in

national storage levels.

Impacts included:


Higher spot wholesale

prices.


Need for thermal generation.


Higher industry carbon

emissions.

Wind generation has stepped

up with Turitea online

throughout 1H24 and initial

generation from Kaiwera Downs

and Harapaki from October and

November 2023 respectively.

Generation by type (TWh)

At the onset of 1H24, hydro storage levels started notably higher than the historical mean but dropped significantly

due to low inflows into both North and South Island catchments. National hydro storage levels were lower on

average, compared to 1H23, increasing the market’s reliance on thermal generation.

•Competition remains intense despite sustained high wholesale futures prices.

Market churn continues to reflect this with switching at 19%.

•New buildings contributed to a continued ~1% p.a. growth in ICPs.

•Tier 1 retailers have a seen a 0.5% increase in market share to ~85% in

December 2023 (84% December 2021). Genesis’s growth is partially driven by

the acquisition of Ecotricity in Feb 2022.

•Tier 2 retailer growth rates have slowed as they have repriced to rising input

costs (energy and networks), resulting in a 1% decline in market share to

~15% (16% December-21) but some (Flick, 2degrees) are growing strongly.

Generation volumes


Hydro generation of 1,916GWh was down 137GWh (7%) on

1H23 following low inflows.


Geothermal generation was up 47GWh (3%) on 1H23,

~34GWh (73%) of the uplift is attributable to the increased

consented mass take from the Wairākei steam field (from

245,000 to 250,000 t/d).


1H24 thermal generation volumes were 526GWh (181%)

higher than 1H23 as depleting hydro storage and the delay to

Tauhara’s online date meant Contact’s increased sales position

was partly backed by thermal generation.

Costs


Renewable generation costs were up $6m (11%) through a

combination of higher insurance, rates, higher geothermal

carbon costs and generalinflationary pressures.


Thermal generation costs, excluding the net release of the

onerous contract provision AGS ($29m), were up $49m (78%)

on increased thermal volumes.


Thermal fuel costs dropped to $96.40/MWh (1H23:

$120.10/MWh) largely due to improved thermal efficiency

following the closure of Te Rapa and a high proportion of TCC

generation (1H23: 11.8 TJ/MWh, 1H24: 8.2 TJ/MWh). This was

slightly offset by increased gas costs (1H23: $7.9/GJ, 1H24:

$8.3/GJ) and higher unit price of carbon (1H23 $43/unit, 1H24

$59/unit).

•Strategic fixed price sales were 122GWh lower than 1H23 (-$8m), reflecting the roll off of

the Fonterra contract following the closure of Te Rapa. Pricing of strategic fixed priced sales

is down $4/MWh as inflationary adjustments to long-term sales were not enough to offset

the mix change from proportionally higher NZAS volume.

•CFD sales volumes were up by 697GWh (+$75m) due to the anticipation of Tauhara

coming online. Prices were up by $32.1/MWh reflecting low hydro inflows over the period

(+$41m).

•Steam sales down on the closure of Te Rapa (-$16.8m).

•Other income was higher (+$4m) mainly due to premiums received from the CfD swaption

deal with Meridian over the period.

1H24 results: Retail business

Retail margins have contracted, driven by sustained high wholesale

prices.

•Retail EBITDAF decreased by $2m on 1H23 largely driven by the

$45m increase in electricity costs that were not fully passed through to

customers.

The Retail business has continued to insulate customers from significant

input cost rises with the forecast annual tariff increase largely in line with

consumer price inflation.

•The average Retail tariff increased on 1H23 reflecting significant

customers rolling off fixed term contracts and targeted retail price rises

to partially offset rising wholesale and network cost increases.

•Around 84% of customers received a price increase in the last 12

months.

•Retail energy tariffs will need to continue to rise to recover the ongoing

elevated wholesale prices and significant network cost increases due

to the 1 April 2025 price regulation reset.

•Contact remains focused on supporting our customers in energy

hardship through ERANZ, with offerings like ConnectMe and

EnergyMate, and directly with community groups.

Connection growth slowed in 1H24 with an increased focus on input cost

recovery.

•Total connections still +20k on 1H23primarily through continued

growth in broadband.

•Multiproduct customers up 9% on 1H23, driven by Time of Use Good

plans growth with high broadband attachment.

Cost to serve – increased by $2/connection largely driven by timing of

marketing spend and higher bad debt. This was partially offset by

productivity improvements through continued growth in digitised

interactions.

•Higher underlying EBITDAF on execution of long-term channel price increases.

•Working capital increase was $33m less than in the prior year due to lower levels of gas storage

following higher thermal generation in 1H24 and seasonal movements in net receivable balances.

•Tax paid is down $10m with final FY23 payment being lower than final FY22 payment.

•Stay-in-business capital expenditure (cash) increase of $9m is linked to accelerated spending

identified to support higher asset availability and output as well as an SAP systems upgrade

project. Accelerated SIB capex programme spend in the period totaled $24m.

•Face value of borrowings (excl. leases) increased by

•A Green Australian Medium Term Note (AMTN) was

issued during the half year, this was partly to

refinance a maturing tranche of USPP in December

2023, but also to provide additional funding for the

ongoing capital investment programme.

•All facilities are classified green under Contact’s

sustainable finance framework, and the bank facilities

are sustainably linked with alignment to the

Contact26 strategy to lead the decarbonisation of

New Zealand.

•The KPIs on Contact’s sustainably linked loan for

emissions reductions and DJSI performance were

met for FY23 providing a discount on the borrowing

rate for Contact.

•Contact’s planning aligns with maintaining its

investment grade credit rating. This requires net debt

to EBITDAF to remain below 3.0x over a sustained

period. Point estimate net debt to EBITDAF is

currently 2.6x and Contact’s EBITDAF outlook, DRP

and capacity for additional hybrid bonds provide the

ability to mange this metric effectively.

Given the requirement for design and construction remediation of the Tauhara steam separation system, Contact is assessing the economic benefits

of all costs capitalised to the project and will complete this assessment prior to the finalisation of the FY24 results.

Any impact would be immaterial in the context of the Tauhara project. The expected FY24 EBITDAF of $620m does not include this potential impact.

1H24 thermal generation volumes were 526GWh (181%) higher than 1H23 due to three factors:

additional thermal generation was required to meet the increased sales position in response to the

Tauhara delay; additional gas was available due to the Methanex outage; and closure of Te Rapa

increased thermal efficiency as more gas was able to be run through TCC.

Operational data

Following the completion of a joint technical working group, set up by Contact and the Ahuroa Gas Storage Facility (AGS) owner FlexGas in 2022,

Contact advised the market in December 2022 that approximately 4PJs of gas owned by Contact and currently stored in AGS may only be

available for extraction at the end of the contract in 2033. Excluding this volume, the estimated storage capacity of the facility is ~6-8PJ (P-50).

EBITDAF is Contact’s earnings before interest, tax, depreciation and amortisation, and changes

in fair value of financial instruments.

EBITDAF is commonly used in the electricity industry so provides a comparable measure of

Contact’s performance.

Depreciation and amortisation, net interest and tax expense are explained on the right.

Reconciliation between Profit and EBITDAF

The adjustments from EBITDAF to reported profit and

movements on 1H23 are as follows:

•Depreciation and amortisation: increased by $15m and

is linked to re assessments in useful life of thermal plant

and Wairākei in light of expected final investment decision

on replacement. This was partially offset by extending the

useful life of SAP assets upgraded as part of recent S/4

Hana upgrade.

•Net interest expense: Lower than 1H23 with higher

capitalised interest on Tauhara and Te Huka projects

partially offset by higher interest on average borrowings.

•Tax expense for the period increasing by $21m following

higher operating earnings.

Non-GAAP profit measure

1

Contact has recognised a net onerous contract provision release for AGS of $29m within EBITDAF and $19m within profit after tax and interest. Underlying performance excludes these impacts. All variances and commentary reflect movements in

underlying performance.

2

Contact has made reclassifications to better align with IFRIC guidance on IFRS 9 resulting in realised gains/losses from market derivatives not in a hedge relationship (includes market making activity) no longer being reported in operating income

(EBITDAF). 1H23 figures restated accordingly.
