Gianluca Palumbo: Thank you, Isabela. Good morning, and thank you for your participation. Let’s start the presentation with our main highlights of the period. Let’s begin with portfolio management. During the quarter, hydrological conditions were favorable, which helped us reduce portfolio risk and supported a stable operating performance across the business. We will come back to this point in more detail later on. At the same time, through EGP Chile, we started the construction of 3 battery energy storage projects in the northern part of the country. These BESS projects will add around 0.5 gigawatts of additional capacity and will play a key role in strengthening the flexibility of our portfolio while supporting our commercial strategy.

In addition, Enel Generacion Chile signed a new LNG supply agreement with Shell. This agreement allows us to better valorize surplus gas volumes already available and to optimize LNG and Argentine gas supply for our generation business. Importantly, this initiative is fully aligned with our long-term business vision for Chile. This is particularly relevant in the context of the growing deployment of battery energy storage systems, which are essential to ensure a more flexible and efficient portfolio. Let’s now move to the country and regulatory context. Starting with the VAD 2020-2024 process, tariff resettlements have been postponed until July 2026. At this stage, the regulator is working on alternative solutions to fund this payment with the objective of avoiding any impact on regulated customers’ tariffs.

Turning to the VAD 2024-2028 process. During the quarter, the regulator published the preliminary technical report, volume 2, in January 2026. Over the next few months, we are awaiting the publication of the final report. Let’s now turn to business profitability. The first quarter of 2026 delivered consistent financial results. EBITDA showed a solid improvement compared to previous years, plus 16% during the period. The extraordinary general meeting approved a capital increase of CLP 360 billion at Enel Distribucion Chile, reinforcing the company’s balance sheet and overall financial flexibility. In addition, the annual general meeting approved the final dividend, fully in line with our commitment to shareholder returns and value creation. In the next slides, we will go deeper into each of these areas and provide further details on the key drivers behind these results.

Let’s move to Slide 4 to talk about hydrology and the progress of our battery energy storage project. Let me begin with our hydro generation. Hydro generation during the quarter remained broadly in line with last year’s levels, as shown on the left-hand side of the slide. For 2026, we are forecasting hydro generation at 10.7 terawatt hours. This assumption is based on a conservative view on hydrology, fully consistent with the average evolution observed over the last 13 years that allows us to confirm our 2026 guidance. This is the case, even though the probability of an El Nino event has increased in recent weeks, with potential impacts mainly expected in the second half of the year. This level of performance is supported by our well-diversified hydro portfolio, together with continuous operational optimization.

Moving now to gas activities. On gas sourcing, we have signed contracts with Argentine gas suppliers with a longer tenure compared to previous years. These contracts secure firm volumes at more competitive prices, providing stable supply until April 2027. In parallel, in the context of high gas prices and the more flexible demand outlook for our thermal fleets, we concluded a negotiation related to our long-term LNG agreement. This approach is well aligned with our view of a gradual ramp-up of battery storage in the coming years, supported by a solid and reliable gas supply from Argentina. Finally, let me focus on battery storage. We continue to strengthen our generation portfolio through the development of battery energy storage systems. These investments will increase the flexibility of our portfolio and support the long-term resilience of our generation mix.

In addition, they will continue to optimize our sourcing strategy. In this context, approximately 450 megawatts of new battery capacity are currently under development and will gradually start operations from [ 12-’27 ] ahead, in line with our planned investment schedule. Now let’s move to Slide 5, where we will review our generation portfolio and the energy balance. Let me start with our generation portfolio. We entered 2026 with a solid and well-diversified portfolio. In fact, our total net installed capacity stands at 8.9 gigawatts, of which 78% comes from renewable energy sources and BESS. Therefore, this structure enhances flexibility and supports a balanced and resilient energy mix. Moving now to our energy balance. During the first quarter of 2026, net production remained stable compared to the same period last year.

This performance reflects the flexibility of our generation portfolio. Higher contributions from wind, solar and efficient natural gas combined cycles more than compensated for the slightly lower hydro generation. Physical energy sales amounted to 7.5 terawatt hours, fully in line with the level recorded in the first quarter of last year. This confirms the stability of our commercial positioning, supported by our diversified sourcing mix. On energy purchases during the quarter, we maintained a similar purchasing mix compared to last year. This included 1.3 terawatt hours of net spot market purchases and 0.8 terawatt hours sourced from third parties. And now I would like to take a moment to share with you some key topics related to the distribution business, which we will cover on the next slide.

Let me start with the tariff review shown on the left-hand side of the slide. We are in the 2024-2028 distribution tariff review process. In January of this year, the regulator released the second version of the technical report. The remaining technical steps are expected to lead a final tariff determination in the second half of 2026. Overall, the review is progressing in line with the regulatory timetable. Turning now to the VAD 2020-’24. The settlement of the outstanding debt with distribution companies, which was originally scheduled to begin earlier, has been postponed to July 2026. For Enel Distribucion, the amount to be received is around USD 65 million, while at the distribution sector level, the total amount involved is approximately USD 900 million.

We remain confident that the process will progress toward the prompt resolution, considering its relevance for the sector and the need for orderly completion. Turning to distribution reform. We continue to see constructive and positive engagement from stakeholders, together with the growing and broad consensus on the need to further evolve and modernize the distribution framework in Chile. This is particularly important in the context of electrification and considering the long-term nature of distribution investments. Finally, a few words on grids and execution. We continue to reinforce specific parts of the network, while at the same time expanding digitalization and remote control solutions across the network. These actions allow us to restore service faster, improving customer experience, and strengthen the flexibility and resilience of our networks.

Overall, execution and distribution remains solid, with a clear and continued focus on service quality. And with that, I will now hand over the presentation to Simone.

Simone Conticelli: Many thanks, Gianluca, and good morning, everyone. I will begin my presentation with an overview of our key results for the period. As shown on the slide, during the first quarter of 2026, EBITDA reached $423 million, with a 16% increase compared to the same period of last year. The improvement was mainly driven by a better integrated margin performance. First quarter net income amounted to $162 million, representing a 7% decrease compared to the result of first quarter 2025, mainly due to higher depreciation following the commissioning of the new renewable plants and lower capitalization of interest. Finally, first quarter FFO reached $122 million, representing a 12% increase compared to the same period last year.

The improvement is due to a combination of several factors, which will be commented on the following slides. And now let’s move to the next slide to talk about the investment made during the quarter. First quarter investment amounting to $111 million were mainly allocated to the development of BESS project, increasing the value of our power plant fleet, and the reinforcement of our distribution network. Let’s review the allocation in more detail. 41% or $46 million were invested in renewable and storage. 31% or $34 million supported thermal power projects. 20% or $31 million was directed toward grids investments. In the renewable segment, we have focused our effort on the development of BESS project, as announced in our strategic plan, on the enhancement of hydro capacity performance, and on the improvement of fleet availability.

In the thermal segment, the priority has been the maintenance and performance enhancement of the power plant fleet. Finally, regarding grids, the focus remain on the resilience program to strengthen the distribution network and ensure service continuity under adverse weather condition. Passing to the nature of investment. First, asset management CapEx totaled $58 million, accounting for 52% of the total CapEx. The main activities have been the maintenance of Atacama, Quintero and San Isidro CCGT, the maintenance of renewable fleet aimed at ensuring plant availability, and some activities for the corrective maintenance and digitalization of grids. Second, development CapEx amounted to $40 million, mainly invested in batteries development, which represented 75% of total, and digital meters and grids remote control equipment.

Finally, customer CapEx totaled $13 million, mainly invested in low and medium voltage connection project and initiative to support load increase. Let’s now go on to the next slide, which provide a closer look at the EBITDA performance. In the first quarter of 2026, our EBITDA reached $423 million. The increase of $58 million compared to the same period of 2025 is mainly explained by the following factors. Starting with the integrated business, we recorded an increase of $67 million, mainly due to, first, lower natural gas costs that reduce the variable production cost of our thermal power plants and the spot energy purchase costs. And second, the positive impact of the optimization of gas sourcing, which allowed us to improve LNG and Argentine gas supply for our thermal fleet, extracting value from our gas contracts portfolio, as previously commented by Gianluca.

These positive impacts were partially offset by the termination of certain high-priced regulated contracts and higher provision related to energy and transmission charges adjustments booked in 2025. Going to grids. We recorded a decrease of 18%, mainly due to the positive impact of issuance provision on 2025 and the impact of the higher O&M expenses associated with the anticipation of the 2026 winter plant activities, partially offset by a higher contribution from complementary distribution activities, mainly related to the new customer connections. Now let’s move to the next slide to review the net income evolution. Net income amounted to $162 million in the first quarter of 2026. The difference compared to the first quarter 2025 is mainly due to the $58 million improvement in EBITDA, thanks to the more efficient sourcing, partially offset by higher depreciation and amortization, mainly related to the commissioning of new renewable capacity in the generation business and higher financial expenses, partially due to lower interest capitalization in the generation business.

And now passing to the next slide, let’s analyze the FFO composition for the first 3 months of 2026. In the first quarter 2026, FFO reached $122 million as a result of the following factors: first, EBITDA totaled $423 million, as previously explained; second, the increase of net working capital amounted to $161 million, mainly due to seasonality of energy payments and gas optimization agreement, for which the payment was registered in April; third, financial expenses amounted to $93 million, also including the settlement of hedging derivatives; finally, income tax expense payments amounted to $48 million, mainly related to generation business. Passing to the comparison with the results of the first quarter of 2025, the 2026 FFO was $13 million higher, mainly thanks to the EBITDA increase for $58 million, the lower increase of net working capital for $27 million, mostly due to lower CapEx payment related to the new development capacity, the positive effect of energy payment scheduling, partially offset by the increase of account receivable following the LNG agreement settled in April, the higher financial expenses for $62 million, and the higher income taxes for $9 million, reflecting higher monthly payment tax rates.

Now let’s take a look at our liquidity and leverage position. Gross debt amounted to $3.9 billion as of March 2026, remaining broadly flat compared to December 2025. The slight increase reflects the seasonal cash and working capital requirements, which were temporarily funded through a $50 million drawdown on the CAF credit line, partially offset by a $9 million reduction in IFRS 16 lease liability. The average term of our debt maturity reached 5.4 years by March 2026 versus the 5.8 years seen in December 2025, and the portion at a fixed rate was 85% of the total debt. The average cost of our debt reached 4.9% as of March 2026, in line with December 2025 figures. Regarding liquidity, we are in a comfortable position to support our capital needs for the upcoming months and cope with next year maturities.

As of March 2026, we have available committed credit lines for $640 million and cash equivalent for $454 million. So thank you all for your attention, and now I will pass the floor to Gianluca for the closing remarks.

Gianluca Palumbo: To conclude, our resilient and diversified business model supported solid and stable results in the first quarter of 2026, even in a volatile operating environment. A well-balanced portfolio combined with disciplined execution continues to provide resilience, allowing us to navigate changes in market and climate conditions with confidence. Second, electrification is clearly emerging as a key driver of demand growth in Chile. This trend is supported by structural developments across mining, industry, transport and electromobility. In this context, we remain closely engaged and well-positioned to support the country’s electrification process, leveraging our integrated offering of clean energy, infrastructure and services.

At the same time, we continue to closely monitor regulatory developments and their potential impacts. Finally, our solid financial position and flexible business model continue to support the execution of our investment plan and our ability to meet financial commitments. This financial strength allows us to continue investing in renewables and battery storage while maintaining financial discipline and delivering sustainable returns to our shareholders. Now let me hand it over to Isabela for the Q&A session.

Isabela Klemes: Thank you very much, Simone and Gianluca. We now start the Q&A. As a reminding, we are receiving questions from our chat on the application. So I will start now, Gianluca and Simone, with the first question. We actually received this question from several analysts, including Andrew McCarthy from LarrainVial. I will do the questions, okay? So the first one is, congrats on the results. Apart from the gas valorization agreement, which is a positive one-off in your results, could you please indicate which other one-off negatives you have incurred in your first quarter 2026 figures? Basically, I’m interested in knowing the recurring EBITDA booked in the first quarter 2026. Actually, on the same, we also received a question regarding what we have mentioned in the EBITDA, regarding the provisions recorded in the first quarter 2026 related to energy and transmission charges. Simone?

Simone Conticelli: So thank you for the question. So you are right, in this quarter, we have more than one nonrecurrent effect. The first one is the impact of the agreement with Shell. That is a positive impact, but then was partially offset by some problem with the transmission line that impacted in our efficiency. And on the other side, this impact can be around $50 million, and then around $60 million of adjustment coming from the previous year. The main part from 2023, it was related to an adjustment of the ancillary services booked in this year after quite a long discussion with the system, we finally take the final decision, and this has an impact of minus $30 million. So to make a synthesis, if you normalize all these nonrecurrent effect, our results is around $360 million, $370 million for the quarter.

Isabela Klemes: Okay. So we are receiving several questions. Let me go to the second one. So the second one is coming from Javier Suarez from Mediobanca. Javier has several questions that I will split here. So the first one is, can you update on the key factors on the ongoing negotiations with regulator of the distribution regulatory framework? And also on the same page on distribution, he also is asking why, in other words, what is the reasons for the postponement of the settlement to July 2026 relating to VAD 2020-2024? Gianluca, this is yours.

Gianluca Palumbo: Yes. Okay. So let me start for the first part. On the distribution regulatory framework, the VAD 2024-2028 process is still ongoing, so the methodology remains based on the reference model company with a regulated real post-tax WACC, as you know, of 6%. We believe there is still room for improvement in the CNE proposal, and we are actively participating with the distribution association in the observation and the discrepancy process. The final technical report is expected by June 2026, and the tariff decree in early 2027. So regarding the postponement of the VAD 2020-2024 settlement, the estimated impact is around USD 765 million. The recovery mechanism was defined by the SEC in February 2026, but collection was postponed by 3 months. So in this moment, our current planning assumption is collection from July 2026, while the Ministry of Energy is also evaluating alternative mechanisms, including potential debt factoring.

Isabela Klemes: Now, another question from Javier. The other question from Javier, Simone, this is for you. Can you give more details on the profitability of the BESS project in Chile in terms of IRR?

Simone Conticelli: Yes, thanks for the question. First of all, let me make a initial comment saying that Enel is developing new BESS, following the strategical goal to balance our portfolio. So first of all, we see this BESS project like an improvement of our portfolio and a way to have some energy shift that can result in a better match between the demand and the production curve. But looking at the BESS project as a stand-alone project, what we can say is that we launch this kind of project only if the return is at least 300 basis points above our WACC. Also that we make also some stress test trying to change the market condition to see the resilience of this kind of project also to some more stressed and critical scenarios.

Isabela Klemes: So move on. The other question is coming from Fernan Gonzalez. This is also for you, Simone, from BTG Pactual. So the question is: why did energy purchase cost in the generation segment increase so much if volumes were similar with last year and its spot prices were significantly below the first quarter 2025 levels, even in the non-solar hours? Simone?

Simone Conticelli: Okay. So in such a way, we answer at the beginning indirectly to this question, because this negative impact from adjustment from the past, entered as sourcing cost, and so You are looking also at the impact of this negative adjustment.

Isabela Klemes: So moving on, we’re receiving a lot of questions. So the next one is coming from Andrew McCarthy, another question from Andrew from LarrainVial. Good morning. Energy losses in the distribution segment continued to deteriorate during the first quarter 2026. Can you comment on what is driving that, how you expect to evolve, and what can be done to reverse the trend? Gianluca.

Gianluca Palumbo: Okay. Thank you for your question. Energy losses increased mainly due to tariff adjustments and some change in customer behavior, which have led to a rise in not technical losses, such as the debt. So in the first quarter, losses were also impacted by lower than expected demand and a more competitive market environment. That said, our loss levels remain below the regional averages, and we have a clear plan to reserve the trend. So we are strengthening our loss reduction strategy through this plan. So first of all, improved inspection targeting using better analytics. Second, expansion of micro and macro metering, so this is an action to help the balance — micro balance. Increased field action and controls, considering the better analysis that we will do.

And finally, enhanced coordination with authorities to address illegal connection. That is one of the problem that we have. So looking forward, we expect losses to gradually decline, targeting around 5.7% by 2028, supported by these operational and technological improvements. That is very important for us.

Isabela Klemes: I’m checking here other questions. Okay. So the other question is coming from Felipe Flores from Banchile Citi. The question is: my question is related to the capital increase in distribution. Will this be subscribed by Enel fully using cash? How does the company plan to finance it, or it’s already covered? How much would take to recover the money? So Gianluca, if you can give some color on the capital increase.

Gianluca Palumbo: Yes, of course. Okay. The capital increase is intended to strengthen Enel Distribucion financial position, and it’s expected to be supported by controlling shareholders in line with its long-term commitment to the business. So from a financial perspective, it will be covered through group level financial resources, ensuring obviously efficiency and flexibility. So in terms of returns, this is not a short-term recovery investment. It supports the long-term sustainability of the business through improved financial structure, lower financial costs and maybe it’s very clear, the ability to execute the investment plan under regulatory framework. This is the last question that I can add in this case. Okay.

Isabela Klemes: I’m checking here. We have receiving another question. Some of them, we have already talked about that is related the capital increase and also on the postponement on the VAD, so I’m continue checking here. Another one was a question also, Gianluca, regarding the VAD 2020-2024, that potentially is going to be a new pack. But Gianluca has already answered this. That is one of the proposals that could be done in order to have the payment on the VAD. So let me — just a second. Okay. So we have other questions that is coming from Juan Felipe Becerra, that is relating — he can — he ask Simone, if you can give more details on the gas optimization contract on Shell. We have already included, but if you can check also.

Now, he has another question. Does this optimization imply lower contracted volumes or changing pricing terms with Shell? And regarding the 3 BESS projects highlighting the presentation, can you provide more details on the expected time line for each project to reach COD and enter in EGP capacity? Simone?

Simone Conticelli: So let’s start talking about the Shell agreement. This is an agreement that has the goal to optimize our portfolio. As you know, we have a very valuable portfolio of gas contracts. Part of the contracts is for GNL. Part of this contract is for gas from Argentina. What I want to stress is that the total amount of volume of gas that we can manage is higher of our needs, even stressing the needs of our power plant during a dry year. So what we have done in this agreement is try to rebalance the amount of the GNL contract to make coherent our portfolio. And we did it in a very right moment in such ways, so we have also positive impact on 2026 results. On the other side, talking about the BESS.

Isabela Klemes: Yes. This is go to Gianluca.

Gianluca Palumbo: So regarding the 3 BESS, to complement, the answer, regarding the 3 BESS projects highlighted in the presentation, let me know that, we could you provide more detail on expected time line. So in this case…

Isabela Klemes: Yes. So the question, Gianluca, was regarding the BESS. What we are expecting the COD on the BESS side. Also what Gianluca was saying that we are expecting — it’s included in our business plan that we have recently presented. And Gianluca, if you want, now your mic is up.

Gianluca Palumbo: Okay. I understand.

Isabela Klemes: Going back again. Thank you.

Gianluca Palumbo: Okay, okay, okay. During 2025, we focused on engineering, permitting and project preparation. With the regulatory framework now in place, we are starting construction in 2026 and expecting the COD during the third and the fourth quarter of 2027. So our strategy also included additional BESS investment, like we presented in the last Capital Markets Day, in 2027 and 2028, reinforcing storage as a core pillar of our portfolio. So we will continue to closely monitor market conditions, maintain flexible approach, focus on profitability and value creation. This is our pillar in our optimization of our portfolio.

Isabela Klemes: Another question is coming from Jay Samani from Scotiabank. This is for you, Simone. SO where do you see Enel Chile next avenues for growth, given that lower demand from unregulated customers? He’s mentioned about the termination of the PPA — regulated PPAs. How is Enel Chile position itself for long-term? And can we expect the company to maintain the current earnings level for growth? He’s asking about our business plan.

Simone Conticelli: So can you repeat me the first part of the question, please?

Isabela Klemes: Yes. Jay is asking you, where do you see that Enel Chile is going? What are the strengths of our plan? He’s also mentioned that we see — we have seen the results, not the reduction of the regulated PPAs, so he’s asking what we are seeing the long-=term? So we are seeing more regulated customer coming on, new auctions, and how we are positioning ourselves in the long-term?

Simone Conticelli: Okay. Enel will confirm its strategy. In this moment, clear we see a reduction in the volumes of regulated contract, but this is related in how the auction now will rise in the market. What we have to stress is that we want the full last to auction also at a valuable price on the market. So we have a very good portfolio in term of price in the short-term. Also, we can stress the fact that the pricing of our portfolio, the average price in the next 3-year, we will maintain the same value, even if the price on the market is going down. And for the full following year, we will keep on looking to a good mix among short-term opportunity and also long-term contract. That can be new regulated auction, but also, long-term contract with the big customer.

Isabela Klemes: We have a last question that is coming from Isabella from Bank of America. So she’s asking: what is the minimal cash position you are operationally comfortable with? You currently have a cash position of around $454 million. Do you plan on using your credit lines this year, or will you refinance your short-term debt?

Simone Conticelli: So thanks for the question. You know that our business has a strong seasonality with some needs in terms of financing in the first and in the second quarter, and then — and higher cash production in the second half. We have an internal model to define the comfortable minimal cash position to cover the net working capital needs. And then for the future financial needs, we plan to refinance using a long-term financing that in this moment is under negotiation.

Isabela Klemes: We do not have any more questions coming here from the chat. So any other doubts that you may have, the Investor Relations team will be fully available to execute other calls and to go into more details. Thank you very much for connecting today. Have a nice holiday. Thank you.

Operator: And this concludes our conference. Thank you for participating, and you may now disconnect.
