[2] All growth or variation references in this Earnings Release refer to 3Q25 compared to 3Q24, unless otherwise stated.

[3] In 3Q24 we started consolidating “Aguas de Origen” (ADO), our water business in Argentina, and in 4Q24 we started consolidating our partnership with the Vierci Group (AV) in Paraguay. Thus, ADO operation is considered organic in 3Q25, by being fully added in last year’s comparison figures in 3Q24. Regarding AV, where necessary, volume figures are isolated in certain sections of this report to provide further clarity on volumes performance.

[4] Organic variations isolate ADO’s accumulated figures as of June 2025 and AV accumulated figures as of September 2025.

[5] Results of 2024 include a non-recurring gain from the sale of a portion of land in Chile, totalizing a gain before taxes of CLP 28,669 million, and a gain after taxes of CLP 20,928 million. At the Operating segments level, this non-recurring effect was accounted in Others/eliminations.

3Q25 PRESS RELEASE

COMMENTS FROM THE CEO

In 3Q25, CCU posted higher operating results and increased profitability versus last year, in a volatile and an uncertain business scenario. Consolidated EBITDA grew 4.6% versus last year, mainly driven by our main Operating segment, Chile, which in a context of soft industries expanded EBITDA and EBITDA margin through gross margin improvements and efficiencies, maintaining the positive trend in financial results throughout the year. The International Business Operating segment also expanded EBITDA versus last year. Within this segment, we are facing a challenging scenario in Argentina, where the beer industry contracted mid-single digit during the quarter. On the other hand, the Wine Operating segment posted a lower EBITDA driven by weaker domestic markets in Chile and Argentina together with a higher cost of wine. Our year-to-date results show that our path to recover profitability remains on track supported by our 2025-2027 Strategic Plan, which prioritizes profitability through revenue management efforts and efficiencies.

Regarding our main consolidated³ figures, in 3Q25 Net sales were down 1.1%, explained by 2.2% lower average prices in CLP partially compensated by a 1.2% volume growth (0.2% expansion when the volumes of AV in Paraguay are excluded). Gross profit decreased 2.9%, and Gross margin was down 79 bps. In addition, consolidated MSD&A expenses in CLP dropped 4.7%, due to efficiencies and a favorable translation effect in Argentina. In all, EBITDA reached CLP 73,635 million, expanding 4.6%, and EBITDA margin expanded 60 bps. For the first nine-months, and excluding the non-recurring gain from the sale of a portion of land in Chile in 2Q24⁴, consolidated EBITDA expanded 9.9%.

In terms of our segments, in the Chile Operating segment top line expanded 1.8%, as a result of a 2.4% increase in average prices, partially offset by 0.6% lower volumes. Higher average prices were explained by revenue management efforts, in all categories, offset by mix effects between categories. Volumes were below last year due to soft industries, mainly in alcoholic categories. Gross profit and Gross margin expanded 3.6% and 75 bps, respectively, due to lower cost pressures related to favorable prices in some raw materials, which compensated higher costs from our PET recycling plant “CirCCUlar”. MSD&A expenses grew 3.2%, below inflation, in spite of higher marketing expenses, and as a percentage of Net sales, increased by 46 bps. Altogether, EBITDA reached CLP 62,756 million, a 4.8% increase, and EBITDA margin expanded 41 bps. Isolating costs and expenses associated to “CirCCUlar”, EBITDA would have expanded 10.2% and EBITDA margin by 117 bps.

In the International Business Operating segment, volumes posted a 5.3% expansion (2.0% increase when the volumes of AV in Paraguay are excluded), although Net sales contracted 8.9%, driven by 13.5% lower average prices in CLP. The decline in average prices in CLP was mainly due to the 42.2%^[6] devaluation of the ARS against the USD, a challenging pricing scenario in Argentina, where prices grew below inflation, and negative mix effects. The volume expansion, excluding AV, was mainly explained by Argentina, fully driven by the water category, while beer volumes contracted in line with the industry. Regarding our other operations, Bolivia and Paraguay posted higher volumes, and Uruguay contracted low-single digit. Gross profit decreased 16.6%, and Gross margin contracted 382 bps. MSD&A expenses were down 19.2%, and as a percentage of Net sales decreased 552 bps. In all, EBITDA grew 73.1% from CLP 3,954 million to CLP 6,845 million, driven by all geographies.

The Wine Operating segment posted a top line expansion of 1.6%, mainly driven by a 4.8% rise in average prices while volumes were 3.0% lower. The higher average prices were mostly explained by a weaker CLP, and its favorable impact on export revenues and revenue management initiatives in domestic markets. Volumes contracted due to a 6.3% decrease in Chile domestic market, in line with the industry, partially offset by a 4.5% growth in exports. Gross profit decreased 1.6%, and Gross margin deteriorated by 128 bps due to cost pressures from a higher cost of wine and higher USD-linked packaging costs. MSD&A expenses rose 4.5%, and as a percentage of Net sales increased 78 bps due to higher marketing expenses. Altogether, EBITDA reached CLP 11,024 million, a 12.0% decrease, and EBITDA margin was down 224 bps.

Regarding our main JVs and associated businesses, in Colombia, we delivered low-double digit volume growth, outperforming the industry. We continue to build a robust brand portfolio and sales execution, which is the path to long-term volume and financial growth.

In summary, in 3Q25, our main Operating segment, Chile, continued in a trend of higher financial results and profitability in a context of soft industries and higher costs from “CirCCUlar”. The latter was boosted by gross margin improvements, efficiencies and lower prices in raw materials. The International Business operating segment posted higher EBITDA, although results were negatively affected by a challenging scenario in Argentina due to a sharp deceleration in consumption. The Wine Operating segment contracted EBITDA due to a higher cost of wine and a weak scenario in domestic markets while exports grew mid-single digits.

We will keep executing our 2025-2027 Strategic Plan and its three pillars, Profitability, Growth and Sustainability, with a special focus on Profitability, supported by both, revenue management efforts backed by our strong and diversified portfolio of brands, and efficiencies across all our operating segments.

3Q25 PRESS RELEASE

CONSOLIDATED INCOME STATEMENT HIGHLIGHTS – THIRD QUARTER (Exhibit 1 & 3)

Net sales were down 1.1%, fully driven by 2.2% lower average prices in CLP, while volumes expanded 1.2% (0.2% growth when AV is excluded). Average prices in CLP were as follow: (i) a 2.4% rise in the Chile Operating segment, related to revenue management initiatives, partially compensated by mix effects between categories; (ii) a 4.8% increase in the Wine Operating segment, mostly explained by a weaker CLP, and its favorable impact on export revenues, and revenue management initiatives in domestic markets; and (iii) a 13.5% contraction in the International Business Operating segment, mostly from a negative translation effect in Argentina, a challenging pricing scenario in this country, where prices grew below inflation, and negative mix effects. Volume growth breakdowns by Operating segments as follows: (i) a 0.6% contraction in the Chile Operating segment due to soft industries, mainly in alcoholic categories; (ii) a 5.3% increase in the International Business Operating segment (2.0% growth when AV is excluded), was mainly explained by Argentina, fully driven by the water category, while beer volumes contracted in line with the industry. Regarding our other operations, Bolivia and Paraguay posted higher volumes, and Uruguay contracted low-single digit, and (iii) a 3.0% contraction in the Wine Operating segment, explained by a 6.3% decrease in Chile domestic market, in line with the industry, partially offset by a 4.5% growth in exports.

Cost of sales grew 0.3%, while Cost of sales per hectoliter in CLP were 0.9% lower. The latter was due to a 7.4% decrease in CLP in the International Business Operating segment, mostly caused by a favorable translation effect, as in local currency COGS per hectoliters grew mainly due to a negative impact from the devaluation of the ARS against the USD in our cost base in Argentina. This was partially compensated by: (i) a 1.1% increase in the Chile Operating segment, mainly associated with higher costs from our PET recycling plant “CirCCUlar”, as isolating its impact, Cost of sales per hectoliter would have decreased 0.5%, due to lower prices in some raw materials such as sugar, fruit pulp, and malt; and efficiencies, and (ii) a 7.1% increase in the Wine Operating segment, from a higher cost of wine and higher USD-linked packaging costs.

Gross profit reached CLP 279,936 million, a 2.9% decrease, and Gross margin was lower by 79 bps.

MSD&A expenses were down 4.7% in CLP, fully explained by a 19.2% contraction in the International Business Operating segment, due to a favorable translation effect, as in local currency MSD&A expenses grew, and as a percentage of Net sales, MSD&A expenses improved 552 bps. In the Chile Operating segment, MSD&A expenses grew 3.2%, below inflation, in spite of higher marketing expenses, and as a percentage of Net sales, increased by 46 bps. The Wine Operating segment posted a 4.5% expansion, due to higher marketing expenses, resulting in a 78 bps increase, as percentage of Net sales.

EBIT reached CLP 36,392 million an expansion of 8.2%, due to the effects mentioned above.

EBITDA reached CLP 73,635 million, a 4.6% increase versus last year. This expansion was mostly driven by a 4.8% increase in the Chile Operating segment and, to a lesser extent, by a 73.1% rise in the International Business Operating segment. On the other hand, these higher results were partially compensated by the Wine Operating segment, which contracted 12.0%. Consolidated EBITDA margin, expanded 60 bps, from 10.6% to 11.2%.

Non-operating result totalized a loss of CLP 28,011 million in 3Q25 versus a loss of CLP 20,069 million last year. This was explained by: (i) a lower result by CLP 13,923 million in Foreign currency exchange differences, mainly explained by Argentina, as most of that lower result is partially offset with gains in Other gains/(losses) associated with a positive result in balance forward contracts in Chile, (ii) a higher loss in Equity and income of JVs and associated by CLP 4,826 million, generated by a lower financial result in Colombia, mostly due to payments related to claims regarding the Consumption tax (ICO, Impuesto al Consumo) basis determination criteria, and (iii) a lower result by CLP 2,607 million in Results as per adjustment units, explained by Argentina, due to accounting effects from being considered a hyperinflationary country. These effects were partially compensated by: (i) a higher gain in Other gains/(losses) by CLP 8,499 million, mostly caused by balance forward contracts, as mentioned above, and (ii) a lower loss in Net financial expenses by CLP 4,916 million, due to a lower debt in Chile and Argentina.

Income taxes reached a positive result of CLP 12,304 million versus a positive result of CLP 18,994 million last year. The lower positive result was mainly explained by a lower taxable income, mostly explained by Argentina, and deferred tax income in Argentina, due to the application of inflation adjustments on fixed assets for tax purposes with a higher positive effect in 3Q24. (See Note 25 Income taxes to the financial statements as of September 30, 2025).

Net income reached a gain of CLP 15,496 million, versus a gain of CLP 29,548 million last year.

3Q25 PRESS RELEASE

CONSOLIDATED INCOME STATEMENT HIGHLIGHTS – 9 MONTHS (Exhibit 2 & 4)

Comments below related to the consolidated and the International Business Operating segment consider organic^[7] figures for volumes, Net sales, COGS and Gross profit; this is, excluding the consolidation of ADO in Argentina and AV in Paraguay^[8]. MSD&A expenses, EBIT, EBITDA, Non-operating results, Income taxes, and Net income are presented on a consolidated basis.

Net sales were up 1.6% organically, mostly driven by 1.0% higher organic average prices in CLP while volumes grew 0.6%. The breakdown of organic average prices in CLP was as follow: (i) a 4.4% rise in the Chile Operating segment, related to revenue management initiatives, partially compensated by mix effects in the portfolio, and (ii) a 4.1% increase in the Wine Operating segment, mostly explained by a weaker CLP, and its favorable impact on export revenues, and revenue management initiatives in domestic markets. These positive effects were in part compensated by a 7.6% contraction in the International Business Operating segment, mostly from a negative translation effect in Argentina, from the devaluation of the ARS against the USD, and a challenging pricing scenario in this country, with prices growing below inflation and negative mix effects. Volume growth was as follows: (i) a 0.1% contraction in the Chile Operating segment, in a context of soft industries, (ii) a 2.5% organic increase in the International Business Operating segment, where we are facing a challenging scenario in Argentina, and (iii) a 0.7% decrease in the Wine Operating segment, explained by a 6.3% decline in the Chilean domestic market, partially offset by a 7.2% growth in exports.

Cost of sales was up 2.1% organically, explained by a 1.5% higher Cost of sales per hectoliter in CLP. The latter was due to: (i) a 4.7% increase in the Chile Operating segment, related to an unfavorable packaging mix and higher manufacturing costs, mainly related with our PET recycling plant “CirCCUlar”, partially compensated by lower prices in raw materials such as sugar, fruit pulp, and malt. Isolating “CirCCUlar”, Cost of sales per hectoliter would have expanded 3.3%; and (ii) a 6.9% increase in the Wine Operating segment, mainly from a higher cost of wine and higher USD-linked packaging costs. These effects were partially offset by a 7.7% organic decrease in the International Business Operating segment, mostly caused by a translation effect, as in local currency Cost of sales per hectoliters grew due to inflationary pressures in Argentina.

Gross profit reached CLP 859,134 million organic, up by 1.0%; organic Gross margin was lower by 26 bps.

MSD&A expenses were up 4.1% in CLP, nearly fully explained by the consolidation of ADO in 3Q24, as, without such consolidation, MSD&A expenses decreased by 0.2%. As a percentage of Net sales improved 71 bps, mostly due to efficiencies. By Operating segment, MSD&A expenses were as follows: (i) a 2.7% expansion in the Chile Operating segment, below inflation, improving 54 bps as a percentage of Net sales due to efficiencies, (ii) a 7.9% increase in the International Business Operating segment, nearly fully explained by the consolidation of ADO, as, without such consolidation, MSD&A expenses contracted by 5.5%. As a percentage of Net sales, MSD&A expenses decreased 234 bps, and (iii) a 0.3% increase in the Wine Operating segment, resulting in a contraction of 86 bps measured as percentage of Net sales, due to efficiencies.

EBIT reached CLP 110,936 million in 3Q25, expanding 15.2% versus last year, the latter excluding the non-recurring gain from a sale of a portion of land in Chile in 2Q24 (EBIT contracted 11.2% when this non-recurring gain is included).

EBITDA reached CLP 225,007 million, a 9.9% increase versus last year, the latter excluding the non-recurring gain from a sale of a portion of land in Chile in 2Q24 (EBITDA contracted 3.6% when this non-recurring gain is included). This expansion was driven by a 8.9% jump in the Chile Operating segment and a 163.0% expansion in the International Business Operating segment, while the Wine Operating segment was down 2.4%.

Non-operating result totalized a loss of CLP 84,952 million versus a negative result of CLP 62,848 million last year. The higher loss was explained by: (i) a higher loss by CLP 9,825 million in Results as per adjustment units, mainly in Argentina, due to accounting effects from being considered a hyperinflationary country, (ii) a higher loss in Equity and income of JVs and associated by CLP 6,514 million, generated by a lower financial result in Colombia, mostly due to payments related to claims regarding the Consumption tax (ICO, Impuesto al Consumo) basis determination criteria, (iii) a larger loss in Other gains/(losses) by CLP 4,219 million, mostly caused by derivative contracts, specifically, forward contracts entered into to mitigate the impact of foreign exchange rate fluctuations on our foreign currency balance positions, which is partially offset in Foreign currency exchange differences in Chile, and (iv) a lower result in Foreign currency exchange differences by CLP 3,985 million explained by Argentina. These effects were partially compensated by a better result in Net financial expenses by CLP 2,437 million due to a lower debt in Chile and Argentina.

Income taxes reached a positive result of CLP 44,978 million versus a positive result of CLP 32,274 million last year. The lower taxes were mainly explained by a lower taxable income, partially compensated by deferred tax income in Argentina, due to the application of inflation adjustments on fixed assets for tax purposes with a higher positive impact in 2024. (See Note 25 Income taxes to the financial statements as of September 30, 2025).

Net income reached a gain of CLP 62,056 million, contracting 5.8% versus last year, the latter excluding the non-recurring gain from a sale of a portion of land in Chile in 2Q24 (Net income contracted 28.5% when this non-recurring gain is included).

[7] Organic variations isolate ADO’s accumulated figures as of June 2025 and AV accumulated figures as of September 2025.

[8] In 3Q24 we started consolidating “Aguas de Origen” (ADO), our water business in Argentina, and in 4Q24 we started consolidating our partnership with the Vierci Group (AV) in Paraguay. Thus, ADO operation is considered organic in 3Q25, by being fully added in last year’s comparison figures in 3Q24. Regarding AV, where necessary, volume figures are isolated in certain sections of this report to provide further clarity on performance.

HIGHLIGHTS BY OPERATING SEGMENTS – THIRD QUARTER

CHILE OPERATING SEGMENT

In terms of our segments, in the Chile Operating segment top line expanded 1.8%, as a result of a 2.4% increase in average prices, partially offset by 0.6% lower volumes. Higher average prices were explained by revenue management efforts, in all categories, offset by mix effects between categories. Volumes were below last year due to soft industries, mainly in alcoholic categories. Gross profit and Gross margin expanded 3.6% and 75 bps, respectively, due to lower cost pressures related to favorable prices in some raw materials, which compensated higher costs from our PET recycling plant “CirCCUlar”. MSD&A expenses grew 3.2%, below inflation, and as a percentage of Net sales, increased 46 bps, due to phasing in marketing expenses. Altogether, EBITDA reached CLP 62,756 million, a 4.8% increase, and EBITDA margin expanded 41 bps. Isolating costs and expenses associated to “CirCCUlar”, EBITDA would have expanded 10.2% and EBITDA margin by 117 bps.

We announced in April this year that we would be celebrating our 175th Anniversary. As one of the ten oldest companies in Chile, CCU launched nationwide a new campaign named "175 Años Juntos". Throughout its history, CCU has cultivated a truly creative and strategic vocation for building brands that have accompanied generations and, in many cases, have become part of the country's cultural imagination. This attribute is well recognized in its brand reputation.

Within Our People Pillar of our Sustainability Strategy, once again CCU obtained the first place in the beverage sector for attracting talent in Chile, according to the 12th edition of the Merco Talento Chile ranking, one of the most renown rankings in Chile which considers professional development, internal promotion, work-life balance, equal opportunities and the reputation of senior management, among others variables.

We continued adding innovations aligned to new trends. Among them, Rockstar Sandía Punch, a new refreshing flavor in the energy drink category, as well as Gatorade Limón, a balanced citrus flavor in the sport drinks category.

INTERNATIONAL BUSINESS OPERATING SEGMENT

In the International Business Operating segment, volumes posted a 5.3% expansion (2.0% increase when the volumes of AV in Paraguay are excluded), although Net sales contracted 8.9%, driven by 13.5% lower average prices in CLP. The decline in average prices in CLP was mainly due to the 42.2%^[9] devaluation of the ARS against the USD, a challenging pricing scenario in Argentina, where prices grew below inflation, and negative mix effects. The volume expansion, excluding AV, was mainly explained by Argentina, fully driven by the water category, while beer volumes contracted in line with the industry. Regarding our other operations, Bolivia and Paraguay posted higher volumes, and Uruguay contracted low-single digit. Gross profit decreased 16.6%, and Gross margin contracted 382 bps. MSD&A expenses were down 19.2%, and as a percentage of Net sales decreased 552 bps. In all, EBITDA grew 73.1% from CLP 3,954 million to CLP 6,845 million, driven by all geographies.

WINE OPERATING SEGMENT

The Wine Operating segment posted a top line expansion of 1.6%, mainly driven by a 4.8% rise in average prices while volumes were 3.0% lower. The higher average prices were mostly explained by a weaker CLP, and its favorable impact on export revenues and revenue management initiatives in domestic markets. Volumes contracted due to a 6.3% decrease in Chile domestic market, in line with the industry, partially offset by a 4.5% growth in exports. Gross profit decreased 1.6%, and Gross margin deteriorated by 128 bps due to cost pressures from a higher cost of wine and higher USD-linked packaging costs. MSD&A expenses rose 4.5%, and as a percentage of Net sales increased 78 bps due to higher marketing expenses. Altogether, EBITDA reached CLP 11,024 million, an 12.0% decrease, and EBITDA margin was down 224 bps.
