Data usage in Africa and the Middle East is set to quadruple by 2030, driving increased demand for towers and additional tenancies.

The cost of smartphones continues to decline rapidly. As devices become increasingly affordable, smartphone adoption is set to expand across

our markets.

Today, 4G is the leading technology across our markets, followed by 3G. Over the next five years 4G is expected to see continued investment, while 5G adoption accelerates and begins to scale, resulting in further densification requirements.

Our business and strategy continued

Robust business model

We build, acquire, lease up and operate mobile towers that can accommodate and power the needs of multiple tenants.

Our tenants are blue-chip MNOs, and we serve them across nine markets in Africa and the Middle East. We offer a high-quality and comprehensive passive infrastructure solution that includes site selection and preparation, maintenance, security,

power management and hosting of active equipment such as antennae.

Our focus on building and acquiring sites with lease-up potential, and providing best-in-class customer service, supports the sustainable expansion of mobile connectivity.

MNOs can roll out and densify mobile coverage faster, more reliably, more cost-effectively and with a lower environmental impact.

We are proud of our role in advancing access to mobile communications in our markets, which in turn contributes to social and economic development.

We have a robust and resilient business model, set up to sustainably deliver digital infrastructure across our markets for decades ahead. Through a combination of high hard-currency earnings, contractual inflation protections, operating to world-class standards and working with top-tier mobile operators, we have a highly visible base of earnings, which is compounded through further expansion across our markets.

2

Colocation lease-up

We adopt a disciplined approach to investments in acquisitions and build-to-suit (BTS) sites, allocating capital to the highest returning opportunities. On average, our new BTS sites are expected to deliver a day-1 site ROIC of 12%1 and have a high probability of lease-up, driving returns higher.

Our BTS model is customer driven, with construction initiated only upon receiving a contractual order from at least one MNO with an initial contractual life of over 10 years.

Build and acquire towers

Strategic Report Governance Report Financial Statements

Our primary focus is to add tenants to our towers (lease-up), sharing space and power equipment, which allows our

customers to roll out quickly and cost-effectively. The majority of tower operating costs are fixed, therefore lease-up delivers strong earnings growth.

Colocation Adjusted EBITDA margins are approximately 80%, which combined with low incremental capex requirements, supports site ROIC of 25% and 34% for 2x and 3x

Operational improvements

tenants respectively1.

We also enhance site performance and returns through power optimisation and the application of Lean Six Sigma (LSS) principles. On average, we target ROIC to exceed 33% on operational initiatives.

For example, fuel remains our most expensive and

carbon-intensive energy source. By investing in power solutions such as grid connections, hybrid systems and solar technologies, we reduce carbon intensity while enhancing financial returns.

1 Site ROIC is for illustrative purposes only, and based on Group average build-to-suit tower economics as of December 2025.

We have a strong foundation of US$5.3 billion contracted revenues with an average remaining life of 6.6 years.

Our business and strategy continued

Disciplined and flexible capital allocation

Since our initial public offering, we have successfully completed two strategies, both ahead of plan and building the platform for the highly accretive growth targeted ahead.

Our first strategy post-IPO was one of expansion. We entered four new markets, doubled the size of our platform and built a high-quality, lease-up-ready portfolio across the region.

Our next strategy focused on integration and lease-up. This phase was transformative as we embedded Business Excellence within our new markets and elevated operations across the Group, leading to accelerated tenancy growth and consistently exceeding market expectations.

As a result, we achieved our 2.2x tenancy ratio target a full year earlier than planned, supporting free cash flow inflection.

Building on this momentum, in November 2025 we announced our next five-year strategic plan: IMPACT 2030.

Through IMPACT 2030, we target generating

>US$1.3 billion of recurring free cash flow, which we will deploy through our disciplined and flexible capital allocation framework.

The first pillar of our framework is optimised organic investments. We target

>US$500 million discretionary capex up to and including 2030 on highly accretive sites, colocations and operational investments.

The second pillar of our framework is shareholder distributions, with

>US$400 million targeted up to and including 2030.

The remaining capacity will be allocated to the highest returning opportunities available to us.

Chair's statement

Connecting communities and businesses through operational excellence



Africa and the Middle East have the lowest mobile penetration and highest population growth globally, which is accelerating the need for more resilient and reliable digital infrastructure.

Through the dedication of our talented local teams and the strength

Strategic Report Governance Report Financial Statements

of our leadership, we continued to meet this strong demand for mobile infrastructure across our markets. In fact, we achieved our five-year tenancy ratio target one year early. Our strong delivery means that over 158 million people now receive reliable mobile network coverage and that all of our stakeholders are experiencing the value we are creating through our infrastructure sharing model."

Sir Samuel Jonah KBE, OSG

Chair

From foundation to IMPACT 2030

In my native country of Ghana, we celebrated an important milestone for our company - 15 years since we became the first independent mobile tower company to operate on the continent.

It was a moment of reflection and pride. Through our infrastructure-sharing model, we supported mobile penetration in Ghana to increase from 35% in 2010 to 59% today.

By enabling faster rollout, lower costs and more reliable power performance, we support mobile operators - and in turn, communities and businesses benefit from the transformative power of connectivity.

Our ability to deliver this impact rests on our people, who continue to demonstrate exceptional drive and commitment to our mission. Through their collective efforts, combined with our uniquely positioned tower platform, we delivered our 2.2x by 2026 strategy one year ahead of plan.

This was our second strategic cycle delivered ahead of expectations, despite the global volatility we have all experienced over the past six years.

As Chair over that period, I have seen our platform go from strength to strength; through doubling in size, increased

resilience and elevated operational capability. It is now primed for the next stage of value creation through IMPACT 2030. This is the

moment we have been working towards: The convergence of industry-leading growth, expanding ROIC, and increasing shareholder distributions.

I am truly excited for this next stage of growth and I know our colleagues, who are also shareholders, are too, with more than half of them joining us for our Capital Markets Day.

Tackling the digital divide

There has never been a more exciting time for mobile development across our markets. While mobile penetration is only 50%

Helios Towers plc Annual Report and Financial Statements 2025

today, similar to the US in the mid-2000s, forecasts point to accelerating penetration over the coming years. Combined with huge population growth, ever cheaper smartphones and forecast 5G adoption we anticipate strong mobile infrastructure demand to continue for decades.

As we expand our tower footprint, we see firsthand how reliable internet access transforms communities across Africa.

Connectivity opens the door to essential services - linking students to digital learning, supporting small businesses as they reach new customers, enabling mobile banking in remote areas and improving access to healthcare.

Every new site we roll out brings greater opportunity, inclusion and resilience, ensuring more people can participate fully in the digital

economy and shape their own futures. 08

1 Refers to the year-on-year reduction in Scope 1 and 2 carbon emissions per tenant (tCO₂e) compared to our baseline year.

Climate action

Across our markets, grid availability averages just 18 hours per day, which makes alternative technologies such as solar, batteries and, where necessary, generators essential to delivering reliable mobile connectivity.

By carefully managing our power solutions and maintaining a strong focus on operational excellence, we delivered record 99.99% power uptime despite the inherent challenges across our markets. This helped ensure people and communities could rely on their mobile connections every day.

At the same time, reducing our reliance on diesel generators remains a major priority. We are shifting towards cleaner energy solutions, strengthening grid connections in partnership with local utility companies and deploying alternative technologies wherever possible. This provides both an environmental and financial benefit to the business.

To accelerate this transition, in 2025 we invested US$11 million in initiatives including grid integration, solar power, advanced battery solutions and remote monitoring systems

to minimise our environmental footprint. Since 2022, we have invested US$44 million through Project 100 and remain on track to invest a total of US$100 million by the end of this decade. As a result, by the end of 2025 we had reduced our scope 1 and 2 carbon emissions per tenant by 10%, as compared to our baseline year. While our fuel reduction investments had been largely offset by accelerated rural rollout, notably in fuel intensive DRC, our tenancy ratio expansion

combined with continued power investments supported a material reduction in 2025.

Local, diverse, talented teams

Our ability to deliver world-class performance in complex environments is powered by the talent, resilience and

commitment of our teams. We have always believed that the best organisations are built locally and grown from within. At the end of 2025, 94% of our colleagues were local, who understand our markets, our customers and our communities better than anyone else.

We are also proud that 79% of our leadership team have been promoted from within -which not only correlates highly with strong performance, it also provides inspiration

for the next generation of talent growing in our markets.

Alongside hiring locally and promoting from within, a key facet of our people strategy is talent development.

This year we continued to expand Lean Six Sigma across the organisation, equipping teams with the tools and confidence

to problem-solve, innovate and deliver consistently high performance. Our digital capability also continued to grow, with more than 20% of our colleagues taking part in coding camps and data-driven programmes.

We remain committed to building a more diverse business. While our industry is traditionally male-dominated, particularly in the markets where we operate, we continue to make progress towards our target of 30% female representation by 2026, reaching 29% in 2025. This is supported by leadership development, structured mentoring and partnerships that are shaping our next generation of leaders.

Our local, talented and diverse teams are united behind a clear strategy and purpose. This is further driven by our HT SharingPlan, which makes every employee a shareholder and allows our success to be truly shared.

We are one team, one business, and our people remain the engine behind our success.

Responsible governance

Strong governance is the foundation of our business and our Board brings together a rich expertise of telecommunications, power, finance and emerging markets. This year I have particularly enjoyed supporting our leadership and talented local teams to develop our IMPACT 2030 strategy.

The Board is confident that our strategy and actions meet the requirements of Section

172(1). Further detail can be found throughout this report, particularly on pages 81-83.

We recognise the importance of a diverse board. We continue to exceed the FCA Listing Rules and Parker Review targets on ethnic diversity, remaining compliant with the FTSE Women Leaders Review recommendation and the FCA requirement for 40% female Board representation and at least one woman in a senior role.

Strategic Report Governance Report Financial Statements

Alongside the governance provided by the Board, our systems and processes have also been developed through our continued partnership with top tier DFI investors such

as British International Investment, DEG, EAIF and the IFC.

Outlook

Looking ahead, I am thoroughly excited about the future of our business. As Africa and the Middle East lead global population growth throughout this century, and as the demand for digital infrastructure intensifies, Helios Towers is well positioned to support this transformation and to help unlock the region's next chapter of development.

Our new strategic plan, IMPACT 2030, reflects a combination of industry-leading growth, ROIC expansion, and shareholder distributions. We are genuinely excited about what we can achieve over the next five years and the impact this will have on the markets and communities we serve.

Helios Towers plc Annual Report and Financial Statements 2025

On behalf of the Board, I extend my sincere thanks to all our stakeholders for their ongoing trust, support and partnership as we begin this exciting new chapter.

Group CEO's statement

IMPACT 2030:

Industry-leading growth, high incremental returns

and shareholder distributions



Strategic Report Governance Report Financial Statements

In 2025 we once again exceeded market expectations, powered by our world-class platform. We achieved our 2.2x tenancy ratio target over one year ahead of plan, while continuing to elevate the customer experience through business excellence. As we look to the year ahead, we enter a new strategic cycle with a well-invested platform, proven operational capabilities and structural growth tailwinds that support sustained value through 2030 and beyond."

Tom Greenwood

Group CEO

IMPACT 2030

2025 was not only our 10th consecutive year of unbroken Adj. EBITDA growth, rising from US$54m in 2015 to US$471m, it was also a pivotal year for the business in several other important ways. As I enter

my 17th year with the Company, I have never been more excited about the opportunities ahead for Helios Towers.

Firstly, 2025 marked the launch of our new five-year strategy - IMPACT 2030 - under which Helios Towers will continue to deliver a global-quality customer experience, invest in high-return growth opportunities, and initiate a new phase of shareholder returns for the first time through our inaugural share buyback and dividend programs.

Secondly, we achieved '2.2x by 2026' - our previous strategy's headline objective of reaching an average of 2.2 tenants per site - more than one year ahead of schedule.

This was a significant achievement for our exceptional teams and demonstrates that our relentless focus on customer experience excellence is building the trust and confidence that enables accelerated rollout, reinforcing Helios Towers as the tower partner of choice in our markets.

Thirdly, our portfolio now provides the daily connectivity needs of 158 million people, 24/7, through nearly 15,000 sites across nine markets. This represents both a significant responsibility and a powerful opportunity.

As we expand our portfolio organically through IMPACT 2030, we targeting covering close to 200 million through our tower footprint.

Most encouraging of all, our growth runway extends well beyond this five-year plan.

The structural drivers across our region -population growth, rising mobile penetration and increasing data consumption - remain firmly in place and these megatrends are set to continue for decades.

Customer Experience Excellence

Helios Towers plc Annual Report and Financial Statements 2025

The CEO of a major customer recently told me: "Your uptime and rollout speed are market leading. Now we want a closer

partnership." That was a valuable challenge, and I understood what they meant. We have been successful executing tangible elements of delivery, but how do we enhance our partnership to enhance their experience with us as we collectively drive mobile growth across our markets?

10



Group CEO's statement continued

This prompted a small but important refinement to our first strategic pillar. Under '2.2x by 2026' it was Customer

Service Excellence; under IMPACT 2030 it is Customer Experience Excellence. While this continues to prioritise critical service metrics - power uptime and rollout speed - it also broadens our focus to the full end-to-

end customer journey when working with Helios Towers.

This refinement means we now consistently ask ourselves:

  • How can we make doing business with Helios Towers the easiest in the market?

  • What currently frustrates customers, and how can we address it?

  • How can we make partnering with Helios Towers a competitive advantage for them?

  • What proactive steps can we take to anticipate opportunities and resolve issues early?

This focus is measurable and already delivering tangible impact. In 2025, we added a record 2,538 new tenancies through closer collaboration with our customers.

Power downtime per tower per week reached a record low of just 1 minute and 10 seconds, improving consistently from over four minutes in 2022. We achieved

record rollout speeds, delivering colocations in two days and build-to-suit sites in 102 days. Through our proprietary Geographic Information System (GIS), network development insight continues to strengthen, and we are now adding a second tenant

to build-to-suit sites after an average of

2.5 years, compared to five years in 2020.

These operational improvements are directly translating into financial momentum, with double-digit Adj. EBITDA and free cash

flow growth now underpinning the dividend and buyback program announced under IMPACT 2030.

As we move through the next cycle, one thing is certain: we will continue to focus relentlessly on customer experience excellence and pursue continuous improvement every day, at every site,

in every market.

People and digital excellence

Helios Towers is an asset-rich business, but its greatest asset is its people. In an increasingly digital age, that statement is even more relevant.

Our ethos is clear: we invest in our people by providing the training, development, tools and opportunities they need to excel and progress. Delivering world-class customer experience depends on world-

class people working together in world-class teams. We therefore set high performance expectations, supported by a culture of learning, curiosity, innovation and agility.

With the right support framework, we actively encourage transparency and learning from mistakes - because that is the fastest route to improvement.

To enable our people to focus on

value-enhancing work and maximise the fulfilment of working at Helios Towers, we have embedded 'Digital by Design' within IMPACT 2030. This is a transformative initiative to integrate AI and digital solutions across approximately 60 identified areas

- from site operations to back-office processes and everything in between.

Our 15 year anniversary celebrations in Ghana

Each opportunity has been assessed against three criteria: financial improvement, customer experience enhancement, and

health & safety advancement. Together, these initiatives will deliver sustained marginal gains, strengthening agility, efficiency and performance throughout this strategic phase.

Our investment in people and digital capability is already delivering tangible results. Today, 94% of our local workforce is local to the markets in which we operate. Lean Six Sigma certification - our foundational business excellence program - now covers 63% of our global workforce, up from 58% a year ago. More than 20% of colleagues participated in coding camps and hackathons in 2025, each developing AI-enabled applications to solve everyday

business inefficiencies. In parallel, our teams completed 71 business excellence projects during the year, generating US$11 million

in savings.

Group CEO's statement continued

And we are not stopping there. As we progress through IMPACT 2030, we will extend capability-building to our

maintenance, build and security partners through our Partner Engagement Programme, including Lean Six Sigma training, governance of business excellence projects and digital collaboration. Through this, we are targeting further improvements in site performance, efficiency and productivity.

Disciplined capital allocation

The business has reached what we call the cash compounding 'sweet spot'. We have achieved sufficient scale to fund all high-return organic growth opportunities while also generating surplus cash flow for sustainable shareholder returns.

This milestone reflects the successful execution of '2.2x by 2026': integrating acquired portfolios that doubled our platform, increasing tenancy ratio from 1.8x to 2.2x, and inflecting free cash flow from consumptive to generative - all of which laid the foundation for IMPACT 2030.

In November 2025, at the launch of IMPACT 2030, we announced our inaugural

shareholder return program as part of a clear capital allocation framework.

Over 2026-30, we are targeting over

>US$1.3 billion of recurring free cash flow. We will deploy over US$0.5 billion into high-returning organic growth to drive at least 9% average annual Adj. EBITDA growth, return over US$0.4 billion to shareholders, and retain the remaining US$0.4 billion of

capital flexibility for the most value-accretive opportunities across the cycle.

Supported by strong structural growth -population, mobile penetration and data consumption - demand for our infrastructure is set to continue for decades, providing long-term compounding cash flows

for investors.

Our 2025 performance sets a strong foundation for the next cycle: revenue increased 8%, Adj. EBITDA rose 12%, recurring free cash flow grew 40%, and free cash flow more than tripled to US$66 million in 2025. Operating profit increased 18% whilst cash from operations rose 21%.

ROIC improved from 13% in 2024 to 14% in

2025, up from 10% in 2022, further widening the spread over our cost of capital and strengthening long-term value creation.

We are targeting a 15-20% ROIC range by 2030.

Outlook

I look to 2026 and the full five-year cycle of IMPACT 2030 with great confidence

and excitement. We enter this new strategic phase with strong operational momentum and financial performance. Our capital allocation framework clearly sets out how we will continue investing in high-returning organic growth while returning at least US$400 million to shareholders. At the same time, our people continue to innovate and strive for excellence across every market and every site.

I remain deeply grateful for the commitment and expertise of our colleagues. With the continued support of our customers, partners and investors, Helios Towers is uniquely positioned to connect people, drive growth and deliver compounding value - today and for decades to come.

Digital inclusion

TH E CHALLENGE

Africa and the Middle East account for the majority of global population growth to 2050 with a 55% increase from today over the next 25 years1. However, there is a major infrastructure and usage gap in Sub-Saharan Africa and the Middle East compared to more developed parts of the

world. Around one billion people across Africa and the Middle East do not use, or are not covered by, mobile broadband2.

TH E OPPORTU NIT Y

By 2050, the number of unique mobile subscriptions in Africa and the Middle East is expected to reach 800 million, an increase of 70% from today3. Over the next five years, our markets are expected to see an additional 91 million mobile connections and fourfold data growth4. Meeting the anticipated future demand for digital services will require expanding our tower infrastructure.

OU R ROLE

With minimal availability of fixed-line internet in our markets, the mobile connectivity powered by our towers has enabled communities to access life-enhancing services, often for

the very first time. Our infrastructure-sharing model and expertise in maintaining reliable power enables MNOs to roll out and densify mobile coverage cost effectively and with

a lower carbon footprint.

Bridging the connectivity and infrastructure divide

Redesigning towers for impact

Since 2024, we have been assessing tower design opportunities for enhancement,

in collaboration with our customers, particularly in locations with limited grid.

Overall the site can be deployed in

two weeks, accommodating up to three tenants, providing faster connectivity for nearby users.

Strategic Report Governance Report Financial Statements

This design uses around half the steel and reinforcement weight and requires only

a third of the concrete compared with

Growing our portfolio to drive digital inclusion

In 2025, we grew our portfolio to 14,746 sites across our nine markets. We had record organic tenancy additions of 2,538, principally colocations, reflecting our focus on customer experience excellence. We achieved our 2026 target tenancy ratio of 2.2x a year ahead of plan, backed by strong lease-up performance. Improved colocation and tenancy ratios allow shared infrastructure

to be used more efficiently, reducing environmental impact per tenant and supporting improved network coverage

for mobile users. As part of our IMPACT 2030 strategy, we plan to grow to over 42,000 total tenancies and a tenancy ratio exceeding 2.5x by 2030.

We continued to see marked improvements in our rollout speed for customers, prioritising safety and efficiency, while reducing our average colocation and BTS delivery times.

Our BTS delivery time has reduced by almost 40% since 2022 and colocation rollout

now averages two days across the Group. We continue to target further improvements through our IMPACT 2030 strategy.

At present, our infrastructure supports reliable connectivity for approximately 158 million people across Africa and the Middle East. To meet the rising demand for data and enhanced connectivity, we

are deploying innovative technologies that extend coverage into areas where traditional tower infrastructure is less effective.

Our suite of solutions addresses the practical challenges of network expansion, such as limited space in dense urban centres, through options like lamppost monopoles as well as lean, space-efficient products designed to optimise performance.

Expanding coverage for underserved communities

Across our markets, governments have set ambitious goals to ensure universal access for the population. For MNOs, rural networks tend to generate lower revenue than urban networks. Our infrastructure-sharing model ensures that rural rollout is more economical for our customers and supports digital inclusion in rural areas.

Mobile connectivity powered by our infrastructure is also fundamental for the transition to a low-carbon economy in our regions. The increasing adoption of 5G and the Internet of Things means that consumers, businesses and public administrations

can apply new technologies that reduce emissions in areas such as transport, manufacturing and agriculture1.

Through enabling mobile connectivity and contributing to social and economic

development in our markets, we contribute to the realisation of all 17 UN Sustainable Development Goals (SDGs). According to GSMA, in 2023, the mobile industry had achieved 58% of its potential contribution to the SDGs - up from 31% in 20152.

Through this approach, a leaner site solution has been developed that removes dependency on fuel-based systems

while continuing to deliver high levels of network availability.

This design requires no heavy machinery, has a smaller carbon footprint and is more cost effective.

traditional designs. For every kilogram of steel saved, approximately 2.3kg of CO₂e is avoided. Similarly, for every cubic metre of concrete saved, about 240kg of CO₂e is avoided.

During 2025, we have deployed this design across several urban sites in Kinshasa, DRC. Based on the success of this rollout, around 500 sites are to be deployed

in 2026.

Climate action

TH E CHALLENGE

Decoupling our business growth - which enables vital connectivity for millions more people - from carbon emissions is a major challenge in the markets where we operate. As we work in regions with some of the lowest electrification rates in the world, we rely on generators to guarantee uninterrupted power for our customers' networks. Our African markets

face some of the most severe impacts of climate change, despite the continent accounting for less than 4% of global CO2 emissions1.

TH E OPPORTU NIT Y

Our markets are on the cusp of a mobile boom. The region would need one million more towers to match the same density per person seen in developed markets such as Europe and the US today2.

OU R ROLE

Our colocation model is the most carbon- and cost-efficient way to deploy the infrastructure network needed to meet the demand for mobile adoption and data consumption expected over the next few years. Increasing colocation, alongside rollout of optimal power solutions, reduces emissions when compared to the traditional operator-owned model.

Reducing our environmental impact and investing in

Strategic Report Governance Report Financial Statements

low-carbon solutions

Our operating context

Optimising our energy consumption and lowering emissions intensity are key levers to reducing our environmental impact.

As electricity supply from the national grids in most of our markets is limited and unreliable, we rely on diesel generators to guarantee power for customers. The diesel and electricity used to power our towers accounts for 99% of our Scope 1 and 2 greenhouse gas (GHG) emissions (see page 24 for more on our carbon emissions data). With diesel being a major contributor to our carbon footprint and operating costs at tower sites, we prioritise reducing diesel usage and maximising the use of grid electricity wherever possible.

However, we have a significant variance in the supply and carbon intensity of grid electricity across our markets, from eight hours a day in DRC to 23 hours in Senegal. The chart shows site-weighted average grid availability per day across the Group - averaging 18 hours

a day. It also illustrates how grid electricity carbon intensity compares to diesel generation in each market, highlighting the emissions benefit of grid-connected sites.

Power uptime for reliable mobile connectivity

Our strategic key performance indicator (KPI) of downtime per tower per week is the average amount of time that our sites are not powered across each week. Working in locations where grid electricity is unreliable or non-existent, we take pride in providing world-class power uptime.

This aligns with our efforts to build resilient infrastructure under SDG 9.

With 90% of mobile users on pay-as-you-go in our markets, 1% of downtime (or 1 hour

40 minutes a week) represents an estimated revenue loss of US$175 million for our customers and a risk of end-users switching to alternative mobile operators1.

In 2025, we achieved one minute and

10 seconds average downtime per tower per week - an 8% improvement on 2024. In May 2025, we achieved our first downtime per tower per week of 0 seconds in Senegal, followed by 0 seconds in Oman in July, reinforcing the improvements across the portfolio and our infrastructure reliability.

Digitalisation

Our IMPACT 2030 strategy places digitalisation at the centre of how the Group enhances performance and resilience.

Helios Towers plc Annual Report and Financial Statements 2025

Through digital twins - data-driven virtual replicas of our physical sites and power systems - advanced data analytics and AI-driven insights, we are developing a Smart Operations Centre that enables real-time monitoring of our sites, improved decision making and optimised power assets across our portfolio. This integrated approach supports stronger network reliability, faster issue resolution and a safer operating environment, while contributing to lower energy consumption, reduced emissions and cost efficiencies.

Sustainable Business Report continued

Our carbon reduction target

We have set a near-term target to reduce Scope 1 and 2 emissions per tenant by 36% by 2030, compared to a 2020 baseline, alongside a long-term ambition to achieve Net Zero by 2040, representing a 90% overall reduction against the same baseline.

Solar site in Oman



Our 2030 target covers Scope 1 and 2 emissions where we can make the most material impact (the diesel and electricity used to power our customers' networks). The target was updated in 2024 to reflect portfolio expansion since 2021, including four additional markets, and our increased exposure to more fuel-intensive geographies where grid infrastructure is limited, particularly in the DRC.

There is a clear correlation between low mobile penetration, limited grid availability and higher carbon intensity per tenant, meaning the markets with the greatest connectivity gaps are often those with the highest operational emissions intensity.

Based on our 2030 target of >42,000 tenancies and the associated growth required to address the mobile infrastructure gap, a 36% reduction per tenant would equate to an increase in absolute emissions of approximately 22% compared to 2020 levels. This tenancy growth reflects the

scale of infrastructure expansion required in Sub-Saharan Africa, where unique mobile subscriber penetration remains below 50% in many markets and electricity access is often unreliable or unavailable. Importantly, this trajectory would still represent a stabilisation of emissions relative to the scale of portfolio growth.

While we support scientific recommendations to limit global warming to 1.5°C, our operating context makes it

challenging to deliver annual absolute Scope 1 and Scope 2 emissions reductions aligned with a Science Based Targets initiative (SBTi)

1.5°C pathway. Our approach prioritises structural reductions in emissions intensity through operational efficiency, electrification, hybridisation and renewable deployment, rather than reliance on carbon offsets.

Our 2040 Net Zero ambition is dependent on the availability of cleaner and reliable national grids and a supportive policy environment for renewable energy and low-carbon technologies. We continue

to engage with policymakers and utility providers to advocate for progress in these areas, recognising that expanded digital infrastructure also plays an important role in enabling emissions reductions across other sectors.

Climate transition plan

Strategic Report Governance Report Financial Statements

We have reviewed the Transition Plan Taskforce (TPT) Disclosure Framework to ensure our climate strategy remains aligned with the evolving external environment and our business priorities. In 2025, we developed a transition plan setting out our pathway to reduce GHG emissions while continuing to deliver resilient digital infrastructure across Africa and the Middle East.

Our pathway is underpinned by clear decarbonisation levers reflected in our investment priorities and emissions reduction glidepath. These include:

  • Colocation growth, which reduces emissions per tenant by sharing infrastructure, power systems and maintenance activity across multiple mobile network operators.

  • Operational optimisation, including improved grid utilisation, energy efficiency and Remote Monitoring Systems to lower fuel consumption.

  • Hybridisation and battery storage, minimising generator runtime at off-grid and limited-grid sites.

  • Renewable energy deployment, particularly solar where technically and commercially viable.

  • Value chain engagement, improving Scope 3 data quality and supporting supplier and customer emissions reductions over time.

Helios Towers plc Annual Report and Financial Statements 2025

Progress towards our 2030 target will be driven by increased colocation and direct carbon reduction initiatives aligned to these levers. Delivery is supported by Project 100, our commitment to invest US$100 million between 2022 and 2030 in proven lower-carbon energy solutions (see page 22).

Our transition plan has been developed with reference to leading frameworks, including TPT, CDP and the European Sustainability Reporting Standards, and will be overseen by the Board and senior management.

We intend to publish the full plan in 2026.

have seen proven to promote energy efficiency and reduce carbon intensity across our portfolio.

Grid connections

We prioritise connecting off-grid sites to the grid to reduce fuel consumption and energy costs.

Investing in grid connections is the most cost-effective power investment we make. By installing new power lines and step-down transformers, and upgrading shared transformers, we ensure stable electricity supply to our sites while also

improving reliability for local communities. These measures significantly reduce reliance on diesel generators and fuel use. We also work with national grid providers to encourage greater access.

Over 100 sites in Tanzania were grid-connected in 2025, taking overall connectivity in the country to above 80%. These sites have created savings of over 80,000 litres of fuel per month.

Sites connected to grid

2024: 80%

RMS and power optimisation

RMS is being integrated with performance dashboards to support performance improvement across sites. As our 'eyes and ears' on a site, it gives real-time information on site power equipment and energy production.

The data received from RMS has been transformational in driving better decision-making on how to optimise the power configuration and efficiency of sites. With the ability to identify and rectify issues such as grid failure, we can improve our power reliability as well as reduce our fuel consumption and emissions.

By the end of 2025, 90% of sites had RMS installed, with an average connectivity of over 95%.



Hybrid solutions

Hybrid installations maximise the power we consume from battery technology, thereby limiting or eliminating generator runtime.

Strategic Report Governance Report Financial Statements

This configuration uses generators with improved efficiency by operating them at a higher load for a shorter time, with the remaining time covered by stored battery energy. The proportion of hybrid sites increased during the year, primarily reflecting improved RMS data accuracy.

We are transitioning to longer-life lithium battery technology, which has improved in cost and power density over recent years - 71% of our hybrid sites now have lithium batteries. As a result of deploying hybrid solutions, in Senegal, we now have 100 generator-free sites.

Hybrid sites

56%

2024: 29%

Solar

We use solar solutions where possible at off-grid and limited-grid sites, depending on factors such as location, space and site performance needs.

With further innovation expected in panel technology, this will be a key solution for our energy-efficiency strategy.

Helios Towers plc Annual Report and Financial Statements 2025

We have deployed over 1,500 solar sites across the portfolio to date. Using learnings across the Group, our Operations team

had their first solar workshop to support deployment during 2025. Our Madagascar operation significantly expanded its solar portfolio from 14 to 116 sites supported by real-time monitoring using RMS to drive fuel and carbon savings.

Solar hybridisation in Ghana

Ghana has become the Group's carbon innovation hub with over one-third of total sites in its portfolio powered by solar, demonstrating how renewable energy solutions can lower emissions while strengthening operational efficiency. In 2023, our Ghana team initiated a large-scale solar hybridisation programme across 409 sites.

A small number of installations were completed in early 2024, to optimise daytime energy consumption through solar generation. Collaboration between functions ensured that solutions were tailored to varying site conditions across the country.

As of July 2025, the original solar installations had generated approximately 1,470,000kWh of energy. This resulted

in fuel savings of about 50,000 litres over the same period, alongside reduced grid dependency during daylight hours. Improved maintenance and panel cleaning further enhanced output, delivering a 27% increase in average weekly solar production. The programme continues to provide important insights for solar deployments across our

Group portfolio.

Powering performance through upskilling

Once we have configured power solutions for each site, we focus on improving the technical skills of our maintenance partners, whose efficient and effective maintenance of our towers contributes to reducing energy consumption - and carbon - prolonging the life of our assets.

In 2025, we worked with our power equipment suppliers to develop training on how to install, use and maintain equipment. Over 950 engineers from our maintenance partner network participated. We have training centres established within each OpCo for practical delivery with interactive videos to improve standards in preventative maintenance.

In DRC, we trained field engineers in end-to-end site integration and

configuration, to ensure sites operate in line with approved design and configuration standards. We tailor our training to support correct site configuration, early detection of deviations and timely remediation to align operational performance with our business excellence standard.

Equipment workshop in Senegal



Operational excellence in DRC

With limited and unreliable grid electricity in DRC - averaging eight hours of grid per day - we rely on generators to maintain site power uptime for our customers.

Our team in DRC delivered a standout operational transformation in 2025

by pairing a comprehensive grid management and fuel reduction programme with the rollout of an operational excellence model.

Through a three-month trial across Kinshasa, Lubumbashi and

Kolwezi, the team introduced a new contractor model that has streamlined operations and reduced site call outs. We have also collaborated with our grid maintenance partner and strengthened governance pathways, significantly reducing overconsumption of fuel and accelerating grid fault resolution.

Combined with investment in our maintenance partner upskilling programme, this has resulted in a fuel reduction of 4.66% per equivalent site, totalling two million litres of fuel reduced compared to 2024. Over the year, these changes have amounted to a 5% reduction in carbon emissions per tenant in DRC.

procedures and training reflect the elevated risk profile of our markets and the nature of our interactions with third parties, including government officials. We continue to use

a third-party risk management platform to screen partners against sanctions and

enforcement watchlists, alongside ongoing monitoring, risk assessments and internal audits. During 2025, we successfully maintained our ISO 37001 Anti-Bribery Management system certification with no non-conformities identified.

Training

We provide ongoing training to strengthen awareness of ethical conduct, bribery and corruption risks, and to empower colleagues to speak up when faced with integrity concerns. All new colleagues receive initial compliance training, complemented by targeted and risk-based sessions for key functions. During 2025, we continued conflict of interest and fraud risk training, supported by scenario-based learning and global anti-bribery and corruption initiatives.

As part of the supplier forum initiative we engaged partners on our Third Party Code of Conduct, human trafficking and modern slavery risks and reporting and collaborative risk mitigation.

In 2025, we launched an Economic Crime and Corporate Transparency Act (ECCTA) risk assessment for the Group with the support of an external partner. As part of the activities, a series of workshops were organised with all OpCos to carry out fraud risk assessment, in light of ECCTA.

Reporting concerns

We encourage colleagues and suppliers to raise concerns through our confidential reporting line, which allows issues to be reported anonymously where preferred. The General Counsel and Company Secretary, Director of People, and Group Head of Compliance receive details of all incidents reported. The Audit Committee

also has oversight of all cases that are logged on the reporting line.

We investigate all concerns in line with our policies, including non-retaliation

provisions, and take appropriate disciplinary and remedial action where required.

Learnings from investigations continue to inform training and awareness activities across the Group, conducted annually.

Cyber security and data privacy Maintaining the security and integrity of our IT systems is critical to maintaining operational excellence and power uptime.

Strategic Report Governance Report Financial Statements

Our incident management and response processes align with the Information Technology Infrastructure Library (ITIL®) framework, covering identification, containment, eradication, recovery and lessons learned. Cyber security and information security updates, including user security, supplier cyber security,

network authentication, AI-enabled security capabilities and business continuity are regularly reported to the Audit Committee by the Group Head of IT Infrastructure

& Cyber Security.

Our strategy focuses on prevention and recoverability, supported by regular testing, independent assurance and Group-wide training. During 2025, we

maintained our ISO/IEC 27001 certification and Cyber Essentials Plus accreditation, while further benchmarking our maturity against recognised industry frameworks. We continue to enhance AI-enabled security technologies to improve threat detection and response, alongside governance and acceptable use controls.

Supplier cyber risk management remains a key focus, with structured assessments of critical third parties and targeted

remediation where required. Looking ahead to 2026, the Group will consider alignment with emerging standards such as ISO/IEC 42001 to further strengthen governance of artificial intelligence within our security and technology environment.

While we do not have direct access to end consumers' data, we process certain personal data in the normal course of

business, including employee and contractor information. We comply with the General Data Protection Regulation and equivalent legislation in other jurisdictions, which governs how personal data is collected, used and protected.

Market and operating review: East & West Africa continued

In 2025, the East & West Africa region delivered resilient organic growth, adding 91 sites and 1,033 tenancies.

This growth was driven by a combination of network densification and rural expansion. 4G connections increased by 3ppt to 33%, while site expansion supported an increase in population coverage of 4 million people.

In terms of market performance, Tanzania continued its strong momentum, adding 669 tenancies, equivalent to 6% growth. Malawi added 212 colocations, representing a 30% increase, and reaching a 2.1x tenancy ratio just three years after acquisition, while Senegal recorded 108 additional tenancies, a 7% increase.

Power price decreases, which reduced revenue and operational expenditure comparably, led to moderated revenue growth of 7% compared to tenancy growth of 8%. However, and as expected, Adj. EBITDA grew 12%, reflecting strong operating leverage as a result of tenancy ratio expansion.

2025 highlights:

  • Strong organic tenancy additions of 1,033 for the region, an 8% increase year on year led by both Tanzania and Malawi with 669 and 256 additions respectively;

  • 0.1x increase in tenancy ratio from 2.1x to 2.2x;

  • 7% increase in revenue to US$348 million reflecting tenancy growth, partially offset by lower power prices in Tanzania;

  • 12% increase in Adjusted EBITDA to US$236 million driven by tenancy growth; and

  • 3ppt expansion in Adjusted EBITDA margin to 68%, driven by margin-accretive tenancy ratio expansion.

World-class power uptime

In August 2025, Helios Towers Senegal became the first of the Group's markets to achieve zero seconds of downtime per tower per week from 5:57 minutes at acquisition. This milestone reflects more than strong technical performance; it demonstrates our culture of

continuous improvement and always striving to elevate our customer experience.

This achievement reflects several years of integrating business excellence, and strong teamwork within our Senegal OpCo. As a result of Lean Six Sigma training, our teams have a data-driven approach to elevating performance. In 2025, this capability combined with the latest remote monitoring technologies, which supported real-time analytics, and supported our best ever year of power uptime.

Market and operating review: Central & Southern Africa continued

Strong population growth and increasing demand for mobile connectivity are driving sustained demand for digital infrastructure across Central & Southern Africa. Accordingly in 2025, we added 231 sites and 1,164 tenancies across the region.

Central & Southern Africa is one of our fastest growing regions, with a population of 252 million today and expected growth of 3% per annum over the next five years.

Mobile penetration has increased over the years, but remains one of the lowest globally at just 43%.

As mobile penetration increases across the region, we are well-positioned to support the demand through our well-invested platform and continued focus on customer experience excellence.

In 2025, tenancy growth of approximately 10%, largely driven by colocations, translated into Adjusted EBITDA growth of 12%.

This demonstrates the sustained and strong link between tenancy growth and Adjusted EBITDA expansion.

Looking ahead, and supported by IMPACT 2030, we are excited by the opportunities across our markets over the next five years, as mobile connectivity adoption continues to rise and demand for higher-quality network services accelerates.

2025 highlights:

  • 1,164 organic tenancy additions, a 10% increase year-on-year;

  • 0.1x expansion in tenancy ratio, reaching

    2.3x (2024: 2.2x);

  • 8% growth in revenue to US$431 million;

  • 12% growth in Adjusted EBITDA; and

  • Adjusted EBITDA margin improved by 2ppt year-on-year to 52%, driven by margin-accretive tenancy ratio expansion.

Scaling connectivity, accelerating growth in DRC

In 2025, our DRC business delivered strong operational performance, including adding 128 sites and 763 tenancies. This performance reflects sustained demand for network expansion and strong execution in one of the Group's largest but least developed mobile markets and we were delighted our roll out expanded our coverage footprint by over one million people.

The DRC continues to represent a significant long-term growth opportunity for the business. At the end of 2025, 24% of the population remained unconnected, making the country one of the most underpenetrated mobile markets globally. This highlights both the scale of the digital inclusion challenge and the critical role of reliable mobile infrastructure in supporting social and economic development.

Market and operating review: Middle East & North Africa continued

In 2025, our Middle East & North Africa business continued to demonstrate strong performance across multiple metrics, adding 99 sites and 341 tenancies.

Since entering the Oman market in December 2022, we have rapidly scaled our presence, and now operate 2,648 sites with 4,529 tenancies. Growth in 2025 was driven by continued 5G adoption and the continued expansion and densification of new entrant, Vodafone.

Tenancy growth of 8% during the year translated into revenue growth of 9% and Adjusted EBITDA growth of 12%, demonstrating strong Adjusted EBITDA

flow-through from tenancy growth. In 2025, average downtime per tower per week improved by 93% YoY, reaching just two seconds, bringing world-class operational standards to Oman and supporting our customer experience focus.

Looking ahead, under IMPACT 2030, we continue to target further lease-up and network densification as 5G rollout accelerates, supporting all three mobile network operators in Oman.

2025 highlights:

  • 341 tenancy additions in the third year of operation, reaching 4,529;

  • Tenancy ratio expansion of 0.1x reaching

    1.7x (2024: 1.6x);

  • 9% growth in revenue to US$74.5 million;

  • 12% growth in Adjusted EBITDA; and

Oman

Delivering on our targets, almost three years ahead of plan

Helios Towers Oman achieved a significant milestone in Q1 25, reaching a 1.7x tenancy ratio and delivering its five-year target almost three years ahead of plan. This performance reinforces its position as one of the Group's fastest-scaling OpCos.

The rapid progress was underpinned by Vodafone's large-scale national rollout, complemented by Omantel's 5G expansion and Ooredoo's network upgrades. These programmes materially accelerated early colocation demand. Close customer engagement further enabled the acceleration and conversion of Omantel's build-to-suit pipeline.

Operational excellence played a central role in this achievement. Markedly improved build-to-suit cycle times enhanced site readiness, supporting earlier tenancy realisation and underpinning the rapid scale-up of the business.

Group CFO's statement

We have entered the cash compounding 'sweet spot' of our story

We achieved our 2.2x tenancy ratio target a full year ahead

Strategic Report Governance Report Financial Statements

of plan, expanded Adjusted EBITDA to US$471 million, achieving 10 consecutive years of growth, more than tripled free cash flow and reduced net leverage to 3.4x.

These achievements underpin the next stage of our journey as we start IMPACT 2030 with momentum. We are well positioned to capitalise on the phenomenal mobile market growth through our best-in-class operational capabilities and our well-invested, colo-ready and financially robust platform."

Manjit Dhillon Group CFO and HT Oman Executive Chair

Robust business model

In 2025, we extended our track record

of consistent delivery, achieving our 10th consecutive year of Adjusted EBITDA growth, despite global pandemics, oil price shocks, rising inflation, rising interest rates and increasing global volatility.

This sustained performance reflects the strength of our business model, which is designed to capture the phenomenal growth drivers in a robust and resilient manner.

This is achieved through a combination of predictable hard-currency earnings, longterm customer partnerships and a disciplined, sustainable pricing strategy. Together, these elements ensure that our financial growth is driven primarily by tenancy expansion and operational excellence, rather than external macroeconomic factors.

Hard-currency earnings

One of the key strengths of the business is our hard-currency earnings. In 2025, 71% of Adjusted EBITDA was generated in

hard-currency, supported by our diversified presence across nine markets. Four of our markets are innately hard-currency, being dollarised or pegged to the US Dollar or Euro, while several of our remaining markets have revenue streams directly linked to hard-currency price structures.

Our contracts also include CPI and power price escalators, providing structural protection against inflation and power price movements. As a result, our Adjusted EBITDA growth continues to be almost entirely driven by tenancy additions and efficiency gains, with limited sensitivity to FX or energy

price volatility. This dynamic was evident again in 2025: despite fluctuations in local currencies, inflation and fuel prices across our markets, Adjusted EBITDA increased to US$471 million, up 12% year-on-year.

Long-term, high-quality contracts

Our customer contracts provide exceptional visibility and security. With initial terms

Helios Towers plc Annual Report and Financial Statements 2025

of 10-15 years, minimal cancellation rights and automatic renewal provisions, our business benefits from stable, long-duration revenue streams.

At the end of 2025, we had US$5.3 billion of contracted future revenue, with an average remaining term of 6.6 years, all without assuming any new business. This contracted foundation gives us confidence in our future earnings and provides a strong platform

for incremental growth as we continue to roll out new sites and add tenants across our portfolio.
