SUMMERSET RELEASES THIRD CLIMATE-RELATED DISCLOSURES

DOCUMENT

Retirement village operator Summerset Group Holdings Limited today released its Sustainability

Review and Climate-Related Disclosures FY25 document, alongside their FY25 Annual Report.

Summerset Chief Executive Scott Scoullar said the company was proud to provide shareholders

and stakeholders with another comprehensive overview of their sustainability work.

“Sustainability and how we live up to our environmental, social and governance (ESG)

obligations, is important to our investors. Summerset prides itself on its sustainability work to

date and we’re pleased to provide a full view of what we’ve done in FY25 and more information

on the risks and opportunities climate changes creates for our business.

“After several years of embedding sustainability into our business, in 2025 we were able to

accelerate our delivery and implement even more meaningful change,” Mr Scoullar says.

“Sustainability and ESG practices are now commonplace throughout Summerset’s business

units and our teams are working collaboratively across multiple projects that impact design,

construction and operations in both New Zealand and Australia.”

A major focus for the year was enhancing energy resilience, including significant progress in the

transition away from gas.

“We’ve recognised the long-term energy-supply risks and emissions profile associated with gas.

In FY25 we set a target to fully remove utility gas from our remaining 28 villages by 2028. Seven

villages transitioned off gas during the year, and we have a clear programme to complete the

remaining sites over the next three years.”

Mr Scoullar said solar energy generation also remains a pivotal part of Summerset’s resilience

and emissions-reduction strategy, providing tangible benefits in terms of reducing power costs

and consumption.

“During FY25 we installed a further 1,500+ solar panels – retrofitting some older villages and

installing many as part of the construction of new buildings too. We’ve also started a pilot

programme offering solar panels for residents on their homes to reduce their power costs and

improve their resilience.

“The pilot kicked off at our Hobsonville village last year and we’ve seen great up take from

residents. We will assess the pilot in 2026 to see if we want to roll it out further.”

Summerset’s award-winning construction waste diversion programme also continued to hit new

standards with 78% of the company’s construction waste diverted from landfill during the year.


Major FY25 sustainability achievements included:

• Installation of more than 1,500 solar panels and launched a resident solar panel pilot

• 5,624 tonnes of construction waste diverted from landfill

• Embodied-carbon baselines established across all of Summerset’s major construction

typologies (e.g. villas, townhouses and village centres completed by FY25)

• All three sustainability linked lending performance targets met again

• Continued progress towards Summerset’s near-term science-based target of a 49%

reduction in Scope 1&2 emissions intensity per sqm by 2028 (against 2022 base year).

Summerset also received external recognition for its sustainability leadership during the year

both at a local and international level.

“In 2025 we won the Corporate ESG category at the Institute of Financial Professionals New

Zealand’s awards, we achieved an A rating from the Carbon Disclosure Project (a signal of

global leadership in climate disclosure and action), our Karaka and Boulcott villages were

recognised by the RVA and the Wellington Regional Business Excellence awards respectively

for their sustainability activities and Forsyth Barr judged us the third highest ranking company

and a "leader" in their ESG ratings for NZX-listed companies.

“It is pleasing to be recognised externally for the work that we do, but we know this is an ever-

changing field and we have to keep working hard to deliver.”

CEO and Board introduction
Welcome to Summerset’s

Sustainability review and Climate

Related Disclosures FY25, for the 12

months ended 31 December 2025.

This report is our fourth sustainability review, and

the third report that includes our mandatory climate

disclosures. This is an important document for us

to provide transparency to our investors, and other

stakeholders, on the work we do, as well as the risks, and

opportunities, that climate change poses for Summerset.

We are proud of the work we have done to date to

impr

ove our environmental, social and governance (ESG)

processes for the betterment of our business and for the

areas we live, work and operate in.

We have successfully embedded sustainability into our

business operations over the last five years and this has

allowed us to move faster in FY25 and do more. During

2025 we focused on resilience, delivering tangible and

real-world impacts against the risks that climate change

poses for us as a business.

Sustainability and ESG practices are now commonplace

thr

oughout Summerset’s business units and our teams

are working collaboratively across multiple projects

that impact design, construction and operations. This

cross-functional approach is embedded across our

portfolio and is central to our transition planning and

sustainability strategy.

This year, we accelerated our transition off

gas, expanded our renewable energy generation

capability

, and continued to set new benchmarks

in waste minimisation with our construction waste

avoidance programme.

We

identified resilience as a key focus as we want to

be able to ensure that our village communities can

operate as independently as possible in the event of

external disruptions, such as major power outages,

wher

ever practicable.

Our achievements have been recognised with industry

awards, and our buildings are being celebrated for

sustainable design.

Gas transition

We recognise the importance of moving away from

natur

al gas and LPG at our villages, both due to the

energy supply risks (in the supply of gas in future as well

as the increasing cost) and because of the climate issues

the use of gas creates.

In FY25, we made the decision to accelerate our

transition away from utility gas, setting a target to

remove gas from our remaining 28 villages by 2028.

During the year we successfully transitioned seven

villages off gas as part of this programme. A small

working group is delivering the transition, and funding

has been allocated to support this important work over

the coming years.

Energy efficiency and renewable energy generation

Solar energy remains a pivotal part of our resilience

plan, while at the same time pr

oviding tangible benefits

to us in terms of reducing our power costs and

grid consumption.

This year we rolled out a further 1,500+ solar panels –

retrofitting some older villages and in the construction

of new buildings. These solar panels are located on

our village centre buildings and provide power for

resident homes and amenities including the café,

pool, indoor cinema, as well as the care centre and

serviced apartments.

Our solar panels at our Richmond village saved

appr

oximately $35,000 in electricity costs in their first

year of operation, a better return than we’d initially

anticipated, and we expect to see similar savings across

our other villages.

As well as our village centre buildings, we are looking at

options f

or our independent living residents. In Q4 we

started a resident solar pilot – putting solar panels on

a number of villas at our Hobson

ville village. We’ve had

strong interest from residents at that village and plan to

run the pilot for a year before we assess its suitability to

roll out the initiative to more villages.

Waste diversion and embodied carbon

Our construction waste diversion targets remain a

continued f

ocus. In 2025 we diverted 5,624 tonnes of

construction waste from

landfill.

We’re looking beyond the construction phase too,

and ha

ve moved towards reduced embodied carbon

CEO AND BOARD INTRODUCTION

products in our civil works phase. For example, our

construction team have sourced underground pipes

with less embodied carbon than products we’ve

used previously, increasing the sustainability of our

future villages.

Embodied carbon refers to the total greenhouse

gas (GHG) emissions associated with the production

of a building's materials, from extraction through

manufacturing, transportation and construction. We

made significant steps in our understanding and

reduction of embodied carbon during FY24 and

we’ve continued that into this year. Understanding

and minimising embodied carbon is crucial in our

efforts to combat climate change and build more

sustainable communities.

Our aim is to use 30% reduced embodied carbon

concr

ete product wherever possible in our New Zealand

builds. We’re also investigating a 37% reduction for parts

of the build at our Half Moon Bay village. This reduces

our climate impact and, helpfully, is cost-neutral.

This year, we took a

significant step forward by

measuring the embodied carbon of our typical village

centre buildings (these house the care centre, serviced

apartments, café and other village amenities) for the

first

time. Results show a reduction in embodied carbon

between the original generation of buildings and the

new versions — similar to the improvements we’ve

previously achieved in our standard villa and townhouse

building typologies.

While we haven’t yet measured all building types,

the

se results reinforce the value of design-led carbon

reduction and support our continued work with

designers, contractors and suppliers to reduce waste

and improve efficiency.

Progress against our targets

We pride ourselves on setting external and internal

per

formance markers that hold us to account. These

are stretch goals that ensure we remain focused and,

in some cases, provide us with added benefits

if we

hit them.

In 2025 we met all of our sustainability-linked lending

(SLL) performance targets again. These targets are

ongoing dementia care certification and increasing

dementia bed provision, reducing emissions intensity per

square metre, and diverting construction and demolition

waste from landfill. Achieving these has triggered a six

basis-points adjustment on our lending and generated

approximately $1.2m in interest savings for us.

Last year, we announced our commitment to a rigorous

ne

ar-term approved science-based emissions reduction

target. This requires a 49% reduction in Scope 1

and 2 emissions intensity per square metre by 2028,

using FY22 as our baseline. In FY25 we achieved a

9% reduction toward this target, excluding the use of

renewable energy certificates (RECs). We remain focused

on delivering this ambitious goal through operational

efficiencies, renewable energy procurement, and our

targeted decarbonisation initiatives.

Toitū-certified

We have made the decision to transition from Toitū Net

C

arbon Zero to being Toitū Carbon Reduce certified.

Transitioning to Toitū Carbon Reduce keeps us within

the r

espected Toitū framework, while focusing on

verified emissions reduction, rather than offsetting our

unavoidable emissions. With our extensive initiatives and

investment (most notably in our gas decarbonisation

acceleration and our successful solar panel roll out)

we believe achieving these goals should be our focus

in the coming years. This strategic shift reflects the

significant

progress we’ve made in the implementation

of our own sustainability initiatives programme and

our confidence to continue executing on reducing our

emissions intensity as a company.

Summerset has held Toitū Net Carbon Zero certification

from 2018 to 2024, during which time we purchased

Gold St

andard verified carbon credits across a mix

of New Zealand and international projects. Our

emissions reporting under Toitū Carbon Reduce will

r

emain independently assured and aligned with our

emissions reduction targets and sustainability-linked

lending requirements.

Social and Governance

Our focus as a business is creating meaningful social

initiativ

es that support our purpose of bringing the best

of life to the more than 9,500 residents who call our

villages home. At a village level we have a large number

of residents who have embraced sustainability – from

food waste minimisation to textile repurposing, creative

reuse of household items, and community recycling

initiatives like battery and soft plastics collection.

At a company level we have continued to invest heavily

in aged care, which is very important to our residents

as well as the communities that we work in. Providing

modern, high-quality aged care is essential to give older

New Zealanders and Australians what they want and

need as their health changes.

During FY25 we opened fully refurbished care centres

at our Havelock North and Trentham villages as well as

completing brand new care centres at Cambridge and

our first one in Australia at Cranbourne North in Victoria.

We are on track to deliver a further five village centre

buildings, all with purpose-built care facilities, in the

next 12–18 months at our Waikanae, Whangārei, Milldale,

Prebbleton and Blenheim villages.

We also employ more than 3,100 people across

Ne

w Zealand and Australia and we continually look

at how we can provide meaningful career pathways

and opportunities for our people to give them every

opportunity to be at their best in and out of work.

A key piece of work for the year was our Employee Value

Pr

oposition (EVP). This is Summerset’s commitment to

our people, and our people’s commitment to each other,

of what they’ll give and receive from working with us.

Our EVP is “Together we bring villages to life” and

contains four promises – Belong, Impact, Inclusion and

05

SUSTAINABILITY REVIEW 2025
CEO AND BOARD INTRODUCTION

Growth. No matter what part of the business our people

work in they are there to bring our villages to life from

the moment we buy land right through to when they are

operational.

The EVP will be a marker and goal that we will hold

ourselves to over the coming years to ensure we’re living

up to the promises we’ve made. For more information on

our work to provide greater social sustainability see the

"Our people and community" and "Our villages sections"

of our Annual Report.

We are very pleased to maintain a consistent and

settled go

vernance structure that continues to adapt

and change to the growing expectations around

ESG accountability

We have a very strong governance structure from our

Boar

d down to ensure that we monitor our risks and that

we have the appropriate skills and experience to help

us to respond to the risks and opportunities that climate

change will present in the future. This includes regular

reviews of ESG indicators, integration of climate-related

risks into strategic planning, and ongoing board-level

engagement with sustainability performance.

External recognition

We were honoured to again be recognised by Forsyth

Barr in their f

ourth Carbon & ESG Ratings for NZX-listed

companies. Summerset was rated the third-highest NZX-

listed company based on their criteria, up from 10th last

year. Forsyth Barr again graded Summerset as a "leader"

among NZX-listed companies for our ESG work.

The Carbon Disclosure Project (CDP), an internationally

r

ecognised disclosure framework that measures

businesses’ competency against a wide range of climate

change measures, has awarded us an A grade this year.

This was a significant improvement against the very

creditable B rating we achieved in recent years. This

rating change recognises our strengthened governance,

improved emissions transparency, and progress against

our emissions reduction targets. Being an A List

company signals global leadership in climate disclosure

and action, and is only achieved by 4% of organisations

who disclose to CDP

.

Our sustainability work was also recognised by the

Institute of Financial Professionals New Zealand (INFINZ),

when Summerset won the Corporate ESG category at

their 2025 awards.

Work continues

We are very proud of the work we’ve undertaken to date.

S

ummerset has continued to increase our resilience

and contribution to New Zealand and Australia’s

climate goals.

We believe we’re meeting our strategic objective

of being a good corporate citizen and positively

contributing to every community we work, and our

residents live, in. However, we know that sustainability

and ESG is an ever-evolving area and we’ll continue to

challenge our thinking, assumptions and the projects we

invest in as well as finding new ways to engage with our

residents and to give them opportunities to contribute to

our ESG work.

We would like to thank the Summerset team for their

dedication to bringing our village

s to life. Thank you also

to our residents, suppliers, stakeholders and investors

for working so collaboratively with us and pushing us to

be better.

SUSTAINABILITY REVIEW 2025
SUMMERSET'S BUSINESS AND STRATEGY

| OUR BUSINESS MODEL AND STRATEGY

Summerset designs, builds, owns and operates

retirement villages. The vast majority of the company's

villages include care centres providing a continuum of

care for residents as their needs change. We currently

have 44 villages either completed or in development (40

in New Zealand and four in Australia), with a land bank

of ten greenfield sites (seven in New Zealand and three

in Australia).

Summerset's purpose is "bringing the best of life". This

motivates the products, services and interactions we

have with our more than 9,500 residents every day.

This purpose is supported by our strategy, split into

key areas that have corresponding short- and long-term

initiatives. Three key areas that drive ESG work are "Be

a good corporate citizen", "become a more efficient and

effective business" and "invest in our people".

Sustainability has been a part of the overall vision at

Summerset since we first measured our carbon footprint

in 2017. We continue embedding sustainability into

key business processes and practices to develop and

operate villages responsibly. This commitment reflects

our vision to create a sustainable future for all—our

residents, employees, and communities—and positions

Summerset to transition alongside the New Zealand

and Australian Governments towards a low-emissions,

climate-resilient future.

Transition plan aspects of Summerset's strategy

What is a transition plan?

The Aotearoa New Zealand Climate Standards

define a

transition plan as part of an entity’s overall strategy that

outlines its targets, including any interim targets, and the

actions it will take to move to a low-emissions, climate-

resilient future. Transition planning involves reshaping

and evolving the business model in response to climate-

r

elated risks and opportunities.

Summerset's approach

Sustainability is embedded across our entire

or

ganisation. Over the past few years, we’ve been

building and refining a circular approach to how we

design, build, and manage our environments. This means

that we consider sustainability through each part of the

process from the start of the village to it's operation, and

back through as we redesign and redevelop or refurbish

the villages we own as they age. This approach informs

decisions at every level and connects our strategy with

our Climate Action Plan and the targets that underpin our

transition, many of which are aligned with climate

science and sustainability performance.

Our transition plan spans the full building and

construction lifecycle, as shown in Figure 1—from design

and procurement through construction, operations,

refurbishment, and end-of-life reuse and recycling. This

integrated view supports resource efficiency and

innovation while enabling us to grow responsibly.

Key elements of our approach include:


Emissions reduction targets

We have committed to near, medium, and longer-

term emissions intensity r

eduction targets. These

targets drive adaptation and continued innovation

across our business model and built environment

portfolio.


Lifecycle integration

Transition planning is embedded across design,

pr

ocurement, construction, operations, and beyond.

Each phase informs the next, enabling continuous

improvement and responsiveness to emerging

technologies, regulatory shifts, and climate science.


Strategic alignment

Our transition planning is closely linked to our ten-

y

ear strategy, Climate Action Plan, and SLL targets.

This alignment ensures coherence across capital

deployment, operational decisions, and long-term

Figure 1: Our transition plan

11

SUSTAINABILITY REVIEW 2025
SUMMERSET'S BUSINESS AND STRATEGY

| OUR BUSINESS MODEL AND STRATEGY

planning. Refer to Table 2 for details of our capital

deployment plan aligned to transition priorities.


Adaptability and resilience

We recognise the need to remain nimble. Our

appr

oach is designed to be flexible, acknowledging

the long lead times in village development and

the evolving nature of climate-related risks and

opportunities. An example of this adaptability is our

decision this year to prioritise gas transition, driven

by the increasing risk of future supply constraints

and potential cost volatility. In response, we have

implemented a new target to get 28 villages off

utility gas by the end of 2028. We are also exploring

r

esident-focused decarbonisation opportunities. In

FY25, we introduced a solar pilot for residents,

enabling them to access renewable energy and

reduce their own carbon footprint.

Our transition approach builds on our circular principles

and r

equires coordinated action across the building and

construction lifecycle. It combines resource efficiency

with innovation and collaboration to deliver on our

low-carbon commitments. Underpinning this approach

is our commitment to near-, medium-, and longer-

term emissions intensity reduction targets. These

intensity-based targets drive continuous adaptation and

innovation across our business model, enabling us to

reduce emissions intensity while continuing to grow.

This transition is supported by strong social initiatives

and governance practices that prioritise resident

wellbeing, aged care investment, and inclusive

career pathways for our people—ensuring sustainability

is embedded across environmental, social, and

governance dimensions.

SUMMERSET'S BUSINESS AND STRATEGY

| CAPITAL ALLOCATION AND INVESTMENT

Alignment with capital deployment and

funding processes

Summerset undertakes detailed financial forecasting,

monthly and annual planning, incorpor

ating our targets,

ten-year strategy, and internal modelling that reflects

climate scenarios. A 50-year horizon is considered for

our build programme. Alongside this, we adopt a long-

term strategic approach to asset management, enabling

climate-related risks and opportunities to be assessed on

a project-by-project basis.

Climate considerations are integrated early in project

feasibility and design, shaping decisions from land

acquisition through to construction. Site selection

includes rigorous assessment of physical risks such as

flooding

and sea-level rise, alongside transition risks

like insurance and managed retreat. This proactive

approach ensures resilience is factored in before

development begins.

During design and refurbishment, we integrate

sustainability initiatives such as designing out waste,

adopting low-carbon materials, and implementing

advanced smart systems for energy and water

optimisation. Our teams continually review, where

applicable, and trial emerging technologies and

processes, including prefabrication techniques and

circular material solutions, to ensure each project

reduces emissions and strengthens long-term resilience.

Supporting this approach is our SLL programme, which

tie

s financial performance to sustainability targets.

To achieve these targets, we maintain an annual

Sustainability Initiatives Budget and Decarbonisation

Fund, alongside

project-specific budgets. Together,

these mechanisms position Summerset to mitigate

climate-related risks while capitalising on opportunities.

Capital investment

Summerset’s Climate Action Plan is primarily supported

thr

ough capital expenditure captured in:


•Sustainability Initiatives Budget (property and asset

management pr

ogramme)

•Decarbonisation Fund (sustainability programme)

•Village Refurbishment Project Budget (design and

de

velopment programme)

Our new village developments and construction

incorporate significant capital investment across all our

successfully embedded sustainability initiatives which

are now standard in our designs. These investments

are not currently tracked or reported on. Additional

expenditure within operational budgets, outside of the

above areas, is also not tracked or reported.  

Planned capital expenditure for FY26 is outlined in Table

2, which details investment directed towards climate-

related risks and opportunities. A key focus this year and

going forward, is the acceleration of our gas transition.

We have committed to removing utility gas from 28

villages by 2028, supported through the Decarbonisation

Fund. This investment reflects our proactive response

to energy market uncertainty - particularly the growing

risk of supply constraints and cost volatility - while

contributing to our broader emissions reductions efforts.

In FY25, ~17% of Summerset’s total capital expenditure

on pr

operty, plant, and equipment for existing sites

was allocated to renewable energy generation, energy

efficiency upgrades and decarbonisation projects. This

represents a slight increase on the previous year.

While opportunities 3 and 4 are included in the Risk and

Oppor

tunities tables (pages 32 and 33), a distinct budget

has not been itemised for these at this stage, as their

associated spend cannot yet be quantified separately.

This does not mean that no resources are allocated but

rather that the activities are integrated into our business-

as-usual operations.

O D E C A R B O N I S E

Summerset’s resident solar pilot at our Hobsonville

village builds on the company’s wider solar roll-

out programme, which began in 2022. This next

step extends our transition planning beyond core

operations by enabling residents in independent villas

to generate renewable energy and reduce their own

carbon footprint.

Under the pilot, rooftop solar panels were installed

on participating residents' villas with Summerset

contributing 50% of the installation cost.

Uptake has been good, with residents embracing the

oppor

tunity to reduce electricity bills and actively

participate in a more sustainable future. Feedback

has also been positive, with residents enjoying the

ability to track their solar generation through an easy-

to-use app.

This initiative

reflects our commitment to innovation

and adaptability, providing valuable insights into

whether a wider roll-out to independent villas across

other applicable villages would be a meaningful next

step in our transition journey.

SCENARIOS

| SCENARIO ANALYSIS

Scenario analysis undertaken

Throughout 2023 and early 2024, Summerset

par

ticipated in both the Construction and Property

Sector, and the Health Sector scenario creation

processes. These two sector scenarios are key

considerations for Summerset due to the nature of

our business as both a constructor and operator

of retirement villages. Both complete sector scenario

analysis documents are available online, including on

the External Reporting Board's (XRB) website.

1

Along

with other key stakeholders within each sector, we

were working group members contributing to the

development of these sector scenarios, with technical

facilitation and support from Beca and Tonkin & Taylor for

the Construction and Property Sector, and Health Sector,

scenarios respectively.

In 2024 Summerset continued to run a stand-alone

process for scenario analysis. This process involved a

detailed breakdown, cross-examination and comparison

of both relevant sector scenarios, with particular focus

on archetypes, reference scenarios, driving forces, key

assumptions and data.

Once this comparison was completed Summerset then

under

took an internal process to select the most relevant

drivers from each sector scenario analysis. This included

examining the drivers and their definitions, including

redefining these drivers to be more Summerset-relevant

as required. Following driver selection, scenarios and

narratives were updated.

These

refined scenarios were then used throughout the

rest of our climate-related disclosures work programme

for 2024. Summerset feels that these updated scenarios

better

reflect the balance between our two core

business functions: the construction and delivery of new

retirement villages, and the operation of our villages,

including providing healthcare to our residents.

For 2025, Summerset opted to continue with a

st

and-alone process and utilising our 2024 scenarios.

Prioritisation was given to incorporate feedback (from

st

akeholders, regulators and analysts) as well as

reviewing our outputs (risks and opportunities). Work has

continued on upskilling the business including greater

focus on Australian involvement and considerations.

Why these scenarios

All three scenarios present plausible futures for

S

ummerset but each scenario demonstrates a different

series of challenges and issues to navigate. The

thr

ee scenarios are detailed on the next pages but

include a 1.5ºC (Orderly) and >3ºC (Hot-house world)

scenarios in line with the requirements of the XRB’s New

Zealand Climate Standards (NZCS). The third scenario

is a middle of the road pathway balancing increased

transition against partially unmitigated physical risks:

2ºC (Disorderly).

Time horizons

Summerset’s scenario analysis is structured around

the thr

ee time horizons set out in Table 3. These

same horizons are used when assessing the potential

impacts of risks and opportunities. We also consider

how uncertainties and assumptions may influence

our responses, and we monitor key information and

emerging trends that help us prioritise action over time.

Scenario analysis process

The scenarios created through both the Construction

and Pr

operty Sector and Health Sector processes were

developed in accordance with the XRB and other

guidance on developing sector scenarios. They followed

the recognised structure of six key steps:


Steps 1 and 2: Engage sector stakeholders

and set

focal questions, scope and timeframe for the scenario

development process.


Step 3: Identify and prioritise driving forces of

r

elevance to the sector. Driving forces, also known

as drivers, are typically broad scale factors which

influence the direction of future change.


Step 4: Select outcomes and pathways combinations

f

or narrative development which are of greatest

relevance and provide the greatest challenge (such

as using the four Network for Greening the Financial

System (NGFS) narrative quadrants).


Step 5: Draft narratives and quantify variables

which follow a clear internal logic. Synthesise any

r

elevant data from existing scenarios and projections.

Generate new data if doing so is feasible and

adds value.


Step 6: Review and

finalise the scenarios. Check the

scenarios are internally consistent and fit for purpose.

Document methodology in a comprehensive report.

When Summerset reviewed both sector scenarios and

undertook our own process, we undertook a shortened

process that focused on step 3 onwards. It was felt

that both sector scenarios covered steps 1 and 2

sufficiently for our purposes and approach. During its

own scenario analysis process, Summerset has not

performed additional modelling beyond that used to

create the existing international scenarios (e.g., SSPs,

RCPs and NGFS scenarios), which were relied on to

develop the sector scenarios.

Throughout the scenario analysis process Summerset's

Climate Working Group acted as the key mechanism

for consulation, feedback and considerations.

Supplementary to this was the additional inclusion of

Summerset's Sustainability Forum as a key stakeholder

from mid-2024 moving forward for all climate-related

disclosures work programme deliverables.

Building on this work, climate‑r

elated risks and

opportunities were assessed against a range of

scenarios, with oversight from the Senior Leadership

Team and review by the Board. The outcomes of this

scenario analysis inform the organisation’s strategy, risk

management approach, and decision‑making.

ORDERLY (1.5ºC)

The world succeeds in limiting global warming to 1.5ºC

abo

ve pre-industrial levels by the end of the century.

This takes a coordinated, ambitious, international and

corporation-led proactive effort of well-signalled and

supported regulatory changes, policies and targets.

With the new policies and regulatory changes, all sectors

are required to play their part and help reduce GHG

emissions. This leads to a prioritisation of electrification

and sustainable practices. Embodied carbon becomes

a main metric for the construction and property sector

to measure and demonstrate the sector’s changing

behaviour and contributions. Additionally, regulations

and policies are put in place to protect vulnerable

populations from the impact of climate change (both

physical and transitional).

New Zealand still experiences extreme weather events

affected by climate change (acute impacts), particularly

in the short- and medium-term, which strongly influence

public support for rapid change. Infrastructure is

prioritised for adaptation rather than resilience. Weather

pattern shifts occur, with increases across measures

such as rainfall, sea level rise and the number of

hot days.

Societal and market behaviour moves rapidly to support

and prioritise change

. Focus and favouritism are given to

sustainable and renewable solutions over fossil fuels and

non-sustainable practices.

DISORDERLY (2ºC)

Average temperature increases are limited to between

1

.5ºC and 2.5ºC above pre-industrial levels by

2100. However, climate change focused policies and

decarbonisation initiatives are not introduced until 2030

(globally, within New Zealand, and within the sector).

Consequentially, it is a rapid, stringent and costly effort

to decarbonise.

From 2030 there is a spike in demand for low carbon

materials and energy efficient technology as change is

now heavily prioritised. Early adopters and fast movers

get the opportunity to utilise materials, expertise and

knowledge, while late movers face increased cost and

competition. During this time critical infrastructure,

particularly the national grid, faces intense pressure

to keep up with the sudden surge of electrification

and transition.

New Zealand still faces extreme weather events and

shifting weather patterns with increases across measures

such as rainfall, sea level rise and the number of

hot days. A lack of action through the 2020s results

in a heightened vulnerability to assets through the

medium term (2030–2050). This significantly increases

the impact of weather-related events and changing

weather patterns as adaptation has not been well

implemented or prioritised.

Following this realisation, protecting vulnerable

populations become

s a priority, with infrastructure,

technology, and decision-making factoring a mixture of

adaptation and resilience.

HOT-HOUSE WORLD (>3ºC)

There is a global focus towards nationalism and security

of r

esources (food, energy, water and space). This

collectively leads to a deprioritisation of climate change

mitigation and adaptation, resulting in a failure to

implement regulations, policies or controls to limit the

effects of climate change.

Consumer and market behaviour remains interested in

climate change but does not drive significant mitigation.

The focus emphasises resilience and responses to

climate-related events rather than proactive adaptation.

Emissions continue to grow unabated, and this leads to

significant shifts in climate patterns and climate-related

extreme weather events.

Average temperature increases exceed 2ºC by 2050

and 3ºC above pre-industrial levels by the end of the

century, resulting in severe physical impacts of climate

changes. There are significant changes in sea level rise,

rainfall intensity and number of hot days, all of which

drive heat-related issues such as illnesses, diseases and

epidemics as well as hampering food production and

living conditions.

This places immense strain and burden upon

communitie

s (particularly the elderly and vulnerable),

the associated services (health, emergency response,

local councils) and critical infrastructure. Net migration

to New Zealand and climate refugees further exacerbate

the issues.

The tables on the following pages set out the key climate-related risks and opportunities that Summerset identified against our three selected scenarios. To determine potential

impact, the

se risks and opportunities were assessed against an internal materiality matrix for each scenario. The exposure and alignment metrics in the tables are new metrics in

FY25 and accordingly comparative information is not included.

Other risks and opportunities that did not meet the materiality threshold have not been disclosed. However, Summerset will continue to monitor the materiality of those risks and

oppor

tunities and adjust our disclosures in future, as required, to reflect changes in materiality.

•Staff

training and equipment to mitigate risk of heat-

related illness (PPE, preventative measures). This also

Assessment and vulnerability

Current

i

mpacts (FY25)

Future impactsManagement actions

Risk:

There is an increasing risk that policy

and regulation changes will be influenced and/

or driven by climate change. Specific examples

relevant to Summerset include:

Embodied carbon requirements

Vulnerability:

100% of Summerset’s business

practices that are considered at risk of regulatory

change affecting embodied carbon

Materiality: Embodied carbon requirements are a

significant consideration as we design, build and

operate our own villages. Summerset has had an

embodied carbon programme in place for the last

three years

Energy fuel profile

Vulnerability:

100% of Summerset’s portfolio

is considered at risk of regulatory change or

policies

affecting our energy or fuel profiles

Materiality:

Summerset’s energy and fuel profile

is significantly material. This is primarily due

to the interlinked nature of emissions reduction

targets and energy profile. Multiple work

programmes are underway

Maximum heat threshold

Vulnerability:

13% of Summerset’s portfolio is

considered at risk of regulatory change or

policies requiring a maximum heat threshold in

our designs

Materiality:

Maximum heat thresholds policy

change has a low materiality as Australia

has established legislation which Summerset

complies with, and New Zealand has no proposed

policy or regulation. However, it is worth

including given the potential risk to residents

In FY25 Summerset

spent $8

00k across

CAPEX initiatives in

current operations such

as solar panel installation

to grow our renewables

generation which can be

attributed to the risk of

energy profile regulation

or change.

Additionally, our

e

stablished embodied

carbon programme

continued. The

attributable cost is

restricted to software

subscription cost ($7k).

The remaining

programme costs are

integrated into business-

as-usual and without

significant

investment,

separating these costs is

not possible.

In FY25 there was

no material impact

design requirements

or regulations.

Scenarios:

(e.g. removal of gas boilers, installation of enhanced

cooling capability)

•change to design standards (e.g. energy

efficiency requirements)

•feasibility of future Summerset’s village and

land acquisitions

•increased costs (OPEX/CAPEX) stemming from

r

equired mitigation, or adaptation measures (e.g.

specific material sourcing)

•increased pressure on critical infrastructure during

ener

gy transitional phases

Anticipated

financial impact: Summerset is expected

to quantify the financial impact of policy or regulatory

change if the legislation or policy is virtually certain, i.e.

it is past select committee stage and the likely financial

impact is material.

Summerset expects that regulatory change has the

potential to significantly affect Summerset and its

operations. The likely outcome is increased CAPEX and

OPEX spending to remain compliant.

However, due to the

significant level of uncertainty

around how, when and what regulatory changes will

affect Summerset, quantification is not possible.

We will continue to take proactive steps to mitigate

potential r

egulatory changes when sufficient certainty

around regulatory and policy direction allows.

Existing mitigations:

•Our embodied carbon programme is

driving man

y different initiatives such

as measurement and reduction, material

innovation and supplier engagement,

design considerations focusing on

reducing waste.

•Achievements include reduced carbon

concr

ete standardised for all new builds,

•increased costs (OPEX/CAPEX) driven by multiple

f

actors such as; achievement of targets, supply chain

volatility, climate resilience programmes, and maintain

reputation or perception

Anticipated financial impact: Current estimates indicate

that achieving the SPT discount level on the SLL will

be between ~$3m and ~$10m savings over the period

2026–2036

This is a present value estimate of the expected savings

Summerset will achieve by meeting between one and three

of the three SLL discount SPT levels annually for the period

2026–2036

Quantification

method: The SLL savings are calculated

based on Summerset’s internal long-term debt forecast

and margin discounts specified on the SLL. Interest

cost savings each year are then discounted back to

31 December 2025 to derive the present value

Key assumptions: One SPT has levels that have been set to

2026, and two SPT have levels that have been set to 2028.

This estimate assumes that the SLL continues to operate

beyond these dates through to 2036 with three SPT, and

similar interest rate savings for meeting the discount level

The SLL also includes neutral levels for each of the three

SPT wher

e no savings will apply to interest costs, as well

as premium levels that must be paid by Summerset as

additional interest cost if any of the three SPT are at or

below premium levels

Summerset’s best estimate is that the discount level will be

met f

or between one and three of the SPT annually, and

for any SPT where the discount level is not met, that the

neutral rate will apply

SUSTAINABILITY REVIEW 2025

METRICS AND TARGETS

| OUR GHG EMISSIONS

We have retained our Toitū Envirocare certification for

FY25, transitioning this year from Toitū Net Carbon

Zero to Toitū Carbon Reduce. This certification requires

annual adherence to rigorous standards and rules, with

a focus on measuring and reducing GHG emissions

in accordance with ISO 14064-1:2018. The Carbon

Reduce programme provides third party certification of

our emissions management approach and reflects our

embedded, company-wide programme of initiatives to

reduce emissions intensity.

Total emissions for the year ended 31 December

2025 were 91,787 tCO

2

e, an increase of 82,980 tCO

2

e

compared to our 2022 base year, primarily driven by

Scope 3 emissions. Scope 3 emissions totalled 86,211

tCO

2

e in FY25, up 26% from FY24, with the majority

attributable to construction activities. Capital goods

and purchased goods and services together accounted

for over 85% of total emissions and 91% of Scope 3

emissions. We measure and report on a selected subset

of Scope 3 categories in line with the Greenhouse

Gas Protocol – A Corporate Accounting and Reporting

Standard (Revised Edition) (GHG Protocol), including

fuel and energy-related activities, waste generated in

operations, business travel, downstream transportation

and distribution, and downstream leased assets. Full

details of our Scope 3 boundaries, methodologies,

assumptions, and exclusions are provided in Appendix

II of this report.

This year, we introduced quantity‑based r

eporting to

assess whether it would improve the accuracy of our

Scope 3 calculations. While this first step covered

only a small portion of our total Scope 3 emissions,

it demonstrated benefits: improved accuracy, better

alignment with our construction activities, and greater

visibility into contributing materials. We continue to

measure embodied carbon across our development

typologies, which helps us understand possible material

choices and identify low-carbon alternatives. Across

our supply chain, we have expanded the use of EPDs,

implemented emissions checklists, and worked closely

with supplier

s to support their own emissions reporting.

Our supplier forums have provided a platform for sharing

best practice and driving engagement on emissions

reduction. These steps are part of our ongoing efforts to

enhance data quality and completeness, and to identify

opportunities for meaningful Scope 3 reductions in our

most high-impact and influenceable areas.

Electricity and gas remain the primary sources of our

Scope 1 and 2 emissions. Our model of care requires

significant and unavoidable electricity demand, while

gas is used for hot water, cooking, and laundry -

core services in aged care. As our resident population

grows, absolute emissions are expected to increase.

Through our gas decarbonisation programme, we are

seeing reductions in Scope 1 emissions from natural gas

and LPG; however, these will be offset over time by

higher Scope 2 emissions as we transition these services

to electricity. Our renewables programme, including

the implementation of solar panels across our village

centres, will help to complement this transition and slow

the growth in Scope 2 emissions. We have already seen

evidence of the positive impact of solar generation, with

strong and consistent generation levels being achieved

across several of our solar-equipped main buildings.

In addition to generating our own renewable energy,

w

e also purchase RECs to support renewable energy

generation in New Zealand and Australia. In New

Zealand, this was achieved through Meridian’s Certified

Renewable Energy product, enabling us to report the

vast majority of market-based Scope 2 emissions as zero,

in line with the GHG Protocol Scope 2 Guidance. RECs

covered all New Zealand sites except for a small office

in Napier, which closed part-way through the year. In

Australia, market-based Scope 2 emissions for all active

construction sites were zero. This was achieved through

100% GreenPower from Shell Energy until August 2025,

after which we transitioned to a Corporate Power

Purchase Agreement (CPPA) with Momentum Energy,

sourcing 100% of our electricity from the Granville

Harbour W

ind Farm, supported by Large-scale RECs. This

does not extend to our Australian office, which remains

outside these arrangements.

A summary of Summerset’s GHG emissions for FY25 is

set out in Table 4 on the following page.

How Summerset calculates GHG emissions

Our GHG emissions have been calculated in accordance

with the GHG Pr

otocol, the GHG Protocol Scope 2

Guidance, and the GHG Protocol Corporate Value Chain

(Scope 3) Accounting and Reporting Standard (2011).

Since we have held Toitū certification since 2018, our

inventory also meets the ISO 14064-1:2018 standard

required to meet certification criteria.

To calculate our emissions, we utilise Toitū’s e-manage

software, which integrates emissions factors and

corresponding global warming potential (GWP) rates.

For FY25, e-manage employed a mix of 2025 and prior

y

ear emissions factors and GWP rates, including:

Across Summerset villages, residents and staff

are finding practical ways to contribute to

their communities— from repurposing textiles to

supporting local charities and driving grassroots

initiatives that reflect care, connection and

everyday action.

Summerset Summerhill, Palmerston North

At Summerhill, the team has started repurposing our

car

e centre linen, towels, and blankets that are no

longer suitable for resident use by donating them

to the SPCA. Items are collected in the laundry and

taken to the SPCA when the box is full. It’s a simple

way to reduce waste and support a local organisation

doing great work in the community.

Summerset at Monterey Park, Hobsonville

Residents at Hobsonville have teamed up with local

textile recycling group ImpacTex NZ to repurpose

clothing and reduce this waste from going to

landfill. This is a resident-driven initiative, with the

group collecting and donating garments. It’s a great

example of people doing good, feeling good, and

being sustainable in everyday ways.

Summerset Mountain View, New Plymouth

At Mountain View, residents creatively linked

Alz

heimer’s month fundraising to sustainability

by selling homemade ‘Enviro-packs’ and knitted

facecloths at Market Day. This initiative was deeply

personal, with long-time volunteers involved with

Alzheimers Taranaki, and it reflects Summerset’s

dementia-friendly v

alues and the power of resident-

led engagement.

percent of the total emissions within their respective

categories, and collectively account for less than five

percent of total emissions and removals. These

exclusions are not considered material to the inventory

or its intended use, or for users relying on this data.

Excluded sources include minor operational activities

such as relocation costs, electricity from data centres

and transmission and distribution losses associated with

natural gas. No exclusions have been applied to Scope 1.

For a breakdown of Scope 2 and 3 exclusions, including

rationale and estimated impact, refer to Table 12 on

page 54 of Appendix II. Methodology, assumptions, data

quality, and uncertainty considerations are detailed in

Table 11 on pages 50 to 54 of Appendix II.

Base year and restatement

Our base year emissions inventory covers the period

1 January

2022 to 31 December 2022. We measure our

emissions annually, in line with our financial reporting

cycle as a publicly listed company. We acknowledge

that the base year does not fully cover several Scope

3 categories across our entire value chain. These

additional categories were first incorporated into our

emissions inventory for FY23.

In FY24, we recalculated FY23 capital goods and

pur

chased goods and services emissions to correct for

deflation or breakdown of basic price, margin and taxes.

This reduced emissions for those categories from 94,716

tCO

2

e to 62,139 tCO

2

e. FY23 employee commuting was

also updated using more accurate emissions factors,

adjusting the total from 3,000 tCO

2

e to 2,268 tCO

2

e.

Since the base year, our reporting scope has grown

to

reflect new entities and sites. For a map listing

our completed, in development and proposed villages

see pages 34 and 35 of our Annual Report 2025. No

recalculations were required this year.

Recalculation procedure

A recalculation procedure is applied to ensure the base

y

ear inventory remains accurate and comparable over

time. The inventory is reviewed annually to

confirm it

reflects current operations.

A quantitative threshold of ±5% is used as the trigger

for material changes. Recalculation may occur under the

following circumstances:

•structural changes - mergers, acquisitions,

div

estments, or outsourcing/insourcing of

emitting activities.

•methodology improvements - updates to calculation

methods, emission f

actors, or activity data that

materially affect base year emissions.

•errors - discovery of

significant errors or cumulative

errors that are collectively material.

In addition to quantitative criteria, qualitative factors are

considered, including:

•timing of emission factor releases.

•financial

and administrative effort required to update

the inventory.

•alignment with science-based targets and frequency

of r

eview.

This approach is consistent with the GHG Protocol and

industr

y best practice.

Assurance of GHG emissions

Summerset’s key metrics, targets, and FY25 performance with prior year comparisons are detailed in the table below. Summerset considers that the target contributes to limiting

global warming to 1.5 degrees Celsius because it has been developed to align with 1.5 degree pathways identified by the IPCC using guidance produced by SBTi. SBTi has

validated our near-term targets (Scope 1 and 2 emissions intensity and Scope 3 supplier engagement) as aligning with a 1.5 degree pathway.

METRICS AND TARGETS

| KEY METRICS AND TARGETS

Clear emissions targets remain central to guiding our

efforts to reduce our emissions intensity and tracking

performance. These targets enable us to focus resources

effectively and assess progress against our sustainability

objectives.

Near-term (five-year) target

A near-term

(five-year) target to reduce Scope 1 and 2

emissions intensity by 49% by FY28, from an FY22 base

year, was approved by the SBTi in 2024. This target

remains unchanged and continues to guide our

decarbonisation efforts.

Our target-setting approach has evolved over time. The

initial goal—a 5

% reduction in emissions intensity

per million dollars of revenue over five years—was

exceeded. In 2022, a science-aligned target was adopted

using the SBTi’s tool and submitted for approval in 2024,

resulting in minor adjustments to the current near-term

target.

Summerset's approved science-based targets:


Scopes 1 and 2 emissions intensity - 49% per square

metre by FY28 from an FY22 base year, aligned with a

1.5

o

C temperature pathway


Scope 3 supplier engagement - 70% of suppliers by

emissions-covering purchased goods and services,

capital goods, fuel and energy-related activities,

upstream transportation and distribution, waste

generated in operations, and business travel to have

science-based targets by 2028 

Medium-term target

Our medium‑term t

argets are embedded within the SLL

facility established in 2021, with no set expiry. Relevant to

climate change, this includes a

confirmed and annually

stepped emissions‑intensity target (through 2026) to

reduce our market‑based Scope 1 and 2 emissions, plus

a small subset of Scope 3 emissions (waste to landfill,

travel, resident electricity, T&D losses and paper). The

emissions‑intensity target under the SLL is aligned with

the science required to limit global warming to 1.5°C. In

2025, the emissions‑intensity discount t

arget was

≤0.0098 tCO

2

e/000 m

2

and the target does not rely on

offsets. Target setting and performance are subject to

independent assurance.

We also have an annually stepped target to reduce

construction waste to landfill (through 2028). In 2025,

the target was an average reduction of >80% in major

metropolitan areas and >41% in regions. We also have

a dementia care bed target, which is not related to

climate change.

We continued to make strong progress against our SLL

t

argets this year. Our construction waste avoidance

programme again exceeded expectations, with all 20

sites in New Zealand and Australia collectively diverting

significant amounts of waste from landfill (see our case

study on page 45). Emissions intensity reduction targets

w

ere met, and dementia care commitments were upheld

through maintained accreditation and the opening of

new memory care centres across our portfolio.

Longer-term (five+ years) target

Our original longer-term science-aligned target was

intr

oduced in late 2020, committing to a 62% reduction

in Scope 1 and 2 emissions intensity per square

metre by 2032, from a 2017 base year. While this

target has not been approved by the SBTi, it remains

aligned with a 1.5°C global warming trajectory. Scope

2 emissions continue to be measured using the market-

based method.

year-on-year. We remain focused on initiatives that

deliver measurable reductions through efficiency,

behavioural change, and technology upgrades.

Industry metrics and emissions intensity

In FY25, Summerset continued to track emissions

intensity using tw

o practical measures: emissions per

square metre and emissions per million dollars of

revenue. These metrics are increasingly referenced

across the sector and help demonstrate efficiency and

progress in reducing emissions relative to growth. Our

results show continued improvement in both measures,

reflecting operational efficiencies and a stronger focus

on the built environment.

Cost of carbon

In FY25, Summerset applied an internal carbon price of

$25 per tonne of CO

2

e (excluding GST) for feasibility and

pr

oject assessments. This price reflects the expected

near‑term cost of acquiring voluntary carbon credits

based on the average cost of Gold Standard

credits purchased in FY24 under Toitū Net Carbon Zero

certification. Following our transition to Toitū Carbon

Reduce, Summerset no longer purchases carbon

credits; accordingly, this price is used as a short‑term

cost assumption and does not represent a forecast of

long‑term transition risk or future carbon prices.

Summerset reviews its internal cost of carbon annually,

and the application of this metric continues to be refined

as learnings are incorporated. 

For comparative purposes, Summerset

first applied an

internal cost of carbon in FY23 at approximately $69 per

tonne of CO

2

e based on the New Zealand Unit (NZU)

market price at year‑end, with an internal carbon price of

approximately $23 per tonne of CO

2

e applied in FY24

following the same approach as FY25 (based on the

e

xpected cost of acquiring voluntary carbon credits). 

GHG emissions intensity reduction and

decarbonisation impact

In FY25, we progressed a range of decarbonisation

initiativ

es (see Table 2 pages 15-16). As we transition

away from gas, electrification reduces emissions from

gas use but increases reliance on grid electricity,

which has its own emissions depending on the grid

average emissions factor. Our emissions profile is also

shaped b

y ongoing growth, with new operational villages

increasing total energy use. While emissions intensity

has generally reduced over time, FY25 saw an increase

overall driven primarily by a change in the New Zealand

grid electricity emissions factor. For performance trends

and methodology notes, see Table 6. For decarbonisation

impact see Tables 7 and 8.

Over the past four years, Summerset has embedded

landfill

avoidance into the heart of our construction

programme. What began as a bold sustainability

initiative has grown into a trans-Tasman effort

spanning more than 20 construction sites across

New Zealand and Australia, involving hundreds of site

personnel, trades, and partner organisations.

The programme launched with a strong commitment

to 100% source separation on-site-a hands-on

approach that built ownership and accountability from

the ground up. While mass balance methods are

now incorporated where appropriate, our foundation

remains rooted in empowering teams to actively sort

and manage waste at source.

Impact in numbers

15,000+ TONNES DIVERTED

10,000+ BINS COLLECTED

26+ WASTE STREAMS TRACKED

~60+% RECOVERY RATE

Targeting impact, Not just the numbers

Each year, our diversion targets increase as part

of our SLL f

acility, reinforcing the connection

between environmental performance and financial

accountability. Construction sites are categorised into

groups to reflect the varying recycling infrastructure

and diversion opportunities across locations.

Our current groupings are Metro and Regions, with a

new Sub-Metro category planned for 2027. To prepare

for this additional challenge, we’ve taken the bold step

to introduce the Sub Metro category internally ahead

of schedule — shifting our Christchurch, Wellington,

and Hamilton construction site

s into this grouping.

This internal move allows us to test and refine our

approach while external targets remain unchanged.

What’s next?

We’re focused on reducing waste at source through

smar

ter design, digital site measurement, and factory-

based solutions for key materials. These types

of innovations help minimise offcuts and improve

material efficiency before waste even reaches the bin.

Our Lost Opportunities Register and enhanced B2B

reporting, help identify service gaps and refine

processes. A monthly cross-functional working group

brings together site teams, sustainability leads, and

industry partners to share learnings and ideas.

Our wider work focuses on refining how we

measure impact and reduce waste at source.

This includes identifying high-volume, low-weight

materials that disproportionately affect landfill space,

understanding how different waste streams influence

landfill longevity, conducting bin audits to inform

smarter procurement decisions, and exploring

material-specific diversion targets to challenge

suppliers. We continue to work closely with our supply

chain partners through our supplier engagement

programme, encouraging better packaging, improved

separation, and transparent disposal practices. It’s

about lifting the entire ecosystem — creating

shared responsibility and driving change beyond our

own sites.

Risk management
SUSTAINABILITY REVIEW 2025

GOVERNANCE

| RISK MANAGEMENT

Integrated risk management process

Summerset acknowledges that the world’s

under

standing of climate change, and how it is

impacting our environments (natural and built), is an

ever-changing area. New sources of data and scientific

information, as well as new regulations and technology,

are constantly shifting the dynamic. This means that

businesses need to be conscious that their management

of climate-related risks is constantly evolving. To address

this, Summerset chose to integrate our climate-related

risks into our existing Enterprise Risk Framework. This

helps keep climate change risks top of mind and builds

engagement across the business.

Our risk management framework and process

Summerset’s Enterprise Risk Framework and Risk

Management P

olicy adopts the principles detailed in

AS/NZS ISO 31000:2018. This helps to ensure that risk

management is well structured and effective throughout

the business.

Risk identification is undertaken by all staff at

Summerset. We use a variety of tools and methods

to help with risk identification. Detailed below are the

specific tools and methods used in identifying our

climate-related risks.

Stakeholder engagement

•The Climate Working Group, and key individuals,

including the Risk and E

xternal Reporting Manager,

worked with the business to assist in understanding,

identifying and assessing climate-related risks across

our entire business.

Village

specific analysis

•Summerset engaged external consultants to help

determine the

specific exposure of identified

physical risks across our portfolio. This was at a

high level and has resulted in a more detailed

investigation programme being created to improve

our understanding of Summerset’s exposure across

multiple scenarios and time horizons.

Scenario analysis

•The scenario creation and analysis processes

(det

ailed in the Strategy section of this report)

helped to identify and assess potential impacts of

climate change, which in turn shaped our climate-

related risks.

External scanning

•Key individuals throughout the business, including

the EL

T, engage with key market participants, external

resources and consultancies to understand potential

changes to existing risks or new and emerging risks.

This helps Summerset with our risk management

through proactive engagement and action.

Risks identified are assessed using Summerset's

Enterprise Risk Matrix based on the consequence of

impact and the likelihood of occurrence. Residual risk

ratings are determined after taking into consideration the

effectiveness of the control environment.

Summerset appreciates that the impacts of chronic,

long-term ph

ysical climate-related risks are not likely

to occur over timeframes that

fit into a traditional

risk matrix.

Therefore, for these specific risks there was greater

emphasis and consider

ation given to the severity of the

consequence. However, we still chose to integrate these

risks so we can track key data and indicators over time

that will help grow our understanding and enable us to

monitor these chronic risks.

All of Summerset’s risks, including climate-related risks,

are managed in line with Summerset’s risk appetite.

Risks are regularly reported on and prioritised for

action according to probability and severity, allowing

for prioritisation of climate-related risks relative to other

types of risks. 

Frequency of risk assessment

The key operational risks for Summerset are reviewed

and r

eported to the ELT monthly, while key strategic risks

are reported to the Board on an annual basis and form

part of our annual risk management plan that is approved

b

y the Board.

In conjunction with our regular reporting of key

operational and strategic risks, the Climate Working

Group will conduct an annual review and update of

climate-related risks, which will run concurrently with our

annual scenario analysis process.

This is not an exhaustive source of climate risks

identification

or assessment, as when business

processes (strategy planning, site identification and

due diligence), stakeholder engagement (regulation and

legislation monitoring, climate scenario sector groups)

or external scanning identify new or changing risks,

Summerset will conduct or update our risk assessments

through the Climate Working Group and Risk and

External Reporting Manager.

Any material change to our climate change risks

outside of r

egular processes would be reported through

the Climate Working Group and Risk and External

Reporting Manager.

Time horizons

Summerset utilises a single time horizon for scenario

analysis as st

ated on Table 3 on page 19. However,

when considering risk management we also consider

more appropriate horizons such as alignment with our

strategy, emission reduction targets, asset life cycle and

age, and financial modelling. This allows us to prioritise

and make timely decisions around mitigation, investment

and overall direction for the company.

Value chain exclusions

No

significant parts of the value chain have been

excluded from the analysis. However, when considering

our supply chain, many suppliers are still early in

their maturity journey. Consequently, Summerset's

understanding of climate-related risks across the whole

value chain, particularly the supply chain, is limited by

availability and quality of data and information.

Emissions sources and calculation methods

Table 11 provides an overview of all emissions sources in Summerset’s GHG Inventory, including data sources, calculation methods, any assumptions made in the calculation

pr

ocess and an assessment of data quality and uncertainty. 

To support our emissions reporting, a variety of calculation methods are used depending on the nature and availability of data:

•supplier-specific method – uses product-specific emissions data associated with goods or services, multiplied by the quantity utilised

•hybrid method – combines

product-specific emissions data (where available) and secondary data (e.g., industry averages) when required

•average data method – estimates emissions by multiplying the quantity of a product (e.g., kilograms, litres) by an appropriate secondary emission factor

•spend-based method – estimates emissions by multiplying the cost of goods and services purchased multiplied by an appropriate dollar spend emission factor.

Assessing GHG emissions remains a developing field, with scientific

understanding and calculation methodologies continuously evolving; while access to data is improving, there

are still estimation uncertainties and limitations in emissions factors. Data quality and uncertainty are assessed using the scales outlined below. Although the quantification of

effects of uncertainty is not included, a qualitative classification of uncertainty is detailed per emissions source.

DATA QUALITY SCALE:

•Low – Data has notable inaccuracies, inconsistencies or variability, which may limit its accuracy

•Medium – Data is generally reliable but contains some inaccuracies or missing values requiring extrapolation

•High – Data is accurate, consistent and mostly complete

UNCERTAINTY SCALE:

•Low – There is strong

confidence in data reliability and accuracy, with clear understanding of limitations

•Medium – There is reasonable confidence in data reliability, with some acknowledged limitations

•High – There is limited confidence in reliability, with reasonable unknowns affecting accuracy

Independent Limited Assurance Report to Summerset Group Holdings Limited

Conclusion

Our limited assurance conclusion has been formed on the basis of the matters outlined in this report.

Based on our limited assurance engagement, which is not a reasonable assurance engagement or an audit, nothing has come to our attention that would lead us to believe that,

in all material r

espects, the the scope 1, 2 and 3 gross greenhouse gas emissions, additional required disclosures and associated methods, assumptions and estimation uncertainty

disclosures included in the Sustainability Review and Climate-related Disclosures FY25 (the Climate Statement) on pages 35 to 37 and Appendix II (GHG disclosures) are not fairly

presented and prepared in accordance with the Aotearoa New Zealand Climate Standards (NZ CSs) issued by the External Reporting Board (the criteria) for the period 1 January

2025 to 31 December 2025.

Information subject to assurance

We have performed an engagement to provide limited assurance in relation to Summerset Group Holdings Ltd’s (the Company) GHG disclosures for the period 1 January 2025 to

31 December 2025.

Below are the locations of the GHG disclosures subject to assurance:

Document classification: KPMG Public.
SUSTAINABILITY REVIEW 2025

APPENDIXAPPENDIX III: GHG ASSURANCE

Criteria

The criteria used as the basis of reporting include the NZ CSs. As disclosed on page 35 of the Climate Statement, the greenhouse gas emissions have been measured in

accor

dance with the World Resources Institute and World Business Council for Sustainable Development’s Greenhouse Gas Protocol Standards (collectively, the GHG Protocol):

•The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (revised edition)

•The Greenhouse Gas Protocol Scope 2 Guidance: An amendment to the GHG Protocol Corporate Standard

•The Greenhouse Gas Protocol: Corporate Value Supply Chain (Scope 3) Accounting and Reporting Standard.

As a result, this report may not be suitable for another purpose.

Standards we followed

We conducted our limited assurance engagement in accordance with New Zealand Standard on Assurance Engagements 1 (NZ SAE 1) Assurance Engagements over Greenhouse

Gas Emissions Disclosur

es and International Standard on Assurance Engagements (New Zealand) 3410 Assurance Engagements on Greenhouse Gas Statements (ISAE (NZ) 3410)

issued by the New Zealand Auditing and Assurance Standards Board (Standard). We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for

our conclusion.

Our responsibilities under the Standard are further described in the ‘Our responsibility’ section of our report.

Other Matter - Prior year comparatives assured by another practitioner

The GHG disclosures for the period ended

31 December 2024, was subject to a limited assurance engagement by another practitioner whose report dated 27 February 2025

expressed an unmodified conclusion on such information. Our conclusion is not modified in respect of this matter.

How to interpret limited assurance and material misstatement

A limited assurance engagement is substantially less in scope than a reasonable assurance engagement in relation to both the risk assessment procedures, including an

under

standing of internal control, and the procedures performed in response to the assessed risks.

Misstatements, including omissions, within the GHG disclosures are considered material if, individually or in the aggregate, they could reasonably be expected to influence the

r

elevant decisions of the intended users taken on the basis of the GHG disclosures.

Inherent limitations

GHG

quantification is subject to inherent uncertainty because of incomplete scientific knowledge used to determine emission factors and the values needed to combine

emissions of different gases.

Use of this assurance report

Our report is made solely for Summerset Group Holdings Ltd. Our assurance work has been undertaken so that we might state to Summerset Group Holdings Ltd those matters we

ar

e required to state to them in the assurance report and for no other purpose.

Our report should not be regarded as suitable to be used or relied on by anyone other than Summerset Group Holdings Ltd for any purpose or in any context. Any other person

who obt

ains access to our report or a copy thereof and chooses to rely on our report (or any part thereof) will do so at its own risk.

To the fullest extent permitted by law, none of KPMG, any entities directly or indirectly controlled by KPMG, or any of their respective members or employees accept or assume any

responsibility and deny all liability to anyone other than Summerset Group Holdings Ltd for our work, for this independent assurance report, and/or for the opinions or conclusions

we have reached.

Our conclusion is not modified in respect of this matter.

Summerset Group Holdings Ltd's responsibility for the GHG disclosures

The Directors of Summerset Group Holdings Ltd are responsible for the preparation and fair presentation of the GHG disclosures in accordance with the criteria. This responsibility

include

s the design, implementation and maintenance of such internal control as Directors determine is relevant to enable the preparation of the GHG disclosures that are free

from material misstatement whether due to fraud or error.

The Directors of Summerset Group Holdings Ltd are also responsible for selecting or developing suitable criteria for preparing the GHG disclosures and appropriately referring to

or describing the criteria used.

Our responsibility

We have responsibility for:

•planning and performing the engagement to obtain limited assurance about whether the GHG is disclosures are free from material misstatement, whether due to fraud or error;

•forming an independent conclusion based on the procedures we have performed and the evidence we have obtained; and

•reporting our conclusion to Summerset Group Holdings Ltd.

Summary of the work we performed as the basis for our conclusion

A limited assurance engagement performed in accordance with the Standard involves assessing the suitability in the circumstances of Summerset Group Holdings Ltd’s use of the

criteria as the basis f

or the preparation of the GHG disclosures, assessing the risks of material misstatement of the GHG disclosures whether due to fraud or error, responding to

the assessed risks as necessary in the circumstances, and evaluating the overall presentation of the GHG disclosures.

We exercised professional judgment and maintained professional scepticism throughout the engagement. We designed and performed our procedures to obtain evidence about

the GHG disclosur

es that is sufficient and appropriate to provide a basis for our conclusion.

Our procedures selected depended on an understanding of the GHG disclosures that is sufficient and appropriate to provide a basis for our conclusion. The procedures we

per

formed were based on our professional judgment and included inquiries, observation of processes performed, inspection of documents, analytical procedures, evaluating the

appropriateness of quantification methods and reporting policies, and agreeing or reconciling with underlying records.

In undertaking limited assurance on the GHG disclosures the procedures we primarily performed were:

•obtained, through inquiries, an understanding of the Company’s control environment, processes and information systems relevant to the preparation of the GHG disclosures.

W

e did not evaluate the design of particular control activities, or obtain evidence about their implementation;

•evaluated whether the Company’s methods for developing estimates are appropriate and had been consistently applied. Our procedures did not include testing the data on

which the e

stimates are based or separately developing our own estimates against which to evaluate the Company’s estimates;

•agreed a selection of GHG emissions data to relevant underlying source documents and re-performed emission factor calculations for a limited number of items;

•performed analytical procedures on particular emission categories by comparing the expected GHGs emitted to actual GHGs emitted and made inquiries of management to

obt

ain explanations for any significant differences we identified; and

•considered the presentation and disclosure of the GHG emissions and explanatory notes against the relevant requirements of the NZ CSs.

The procedures performed in a limited assurance engagement vary in nature and timing from and are less in extent than for a reasonable assurance engagement. Consequently,

the le

vel of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance

engagement been performed.
