CEO Message

Commenting on the results for the quarter Mr. Martín Eurnekian, CEO of Corporación América Airports, noted: “We delivered a strongstart to 2026, with broad-based growth across our airport network and continued progress on our key financial metrics. Total traffic increased7% year-over-year to 21.8 million passengers, led by a 14% increase in international traffic, with positive international performanceacross every country in which we operate. Revenues excluding construction services rose 19% year-over-year, supported by solid growthin both aeronautical and commercial revenues and, once again, outpacing passenger traffic growth.

Profitability also advancedmeaningfully during the quarter. Adjusted EBITDA excluding IFRIC 12 increased 26% year-over-year to $196 million, while the correspondingmargin expanded 2.3 percentage points to 39.6%. These results reflect the continued benefits of our diversified platform, active commercialexecution and disciplined cost control.

Argentina was an importantdriver of performance, with strong growth in international travel helping to offset softer domestic demand, which was impacted by temporaryoperational disruptions during the quarter. Across the rest of the portfolio, we also continued to see positive trends. Brazil posteda strong recovery, while Italy and Uruguay benefited from healthy international demand, Ecuador continued to grow despite security-relatedchallenges, and Armenia remained resilient, supported by greater connectivity and a more limited-than-expected impact from the conflictin the Middle East.

Our financial position continuedto strengthen. Cash and cash equivalents reached $666 million at quarter-end, and net leverage stood at 0.5x, reflecting higher AdjustedEBITDA, strong cash generation and disciplined capital allocation. This strong balance sheet provides flexibility to fund committed investmentprograms, as well as to continue evaluating growth opportunities.

On the strategic front, wecontinue to advance our growth agenda with discipline. Following the concession awards received in Iraq and Angola, we are in ongoingdiscussions with the respective governments to finalize the terms of the concession agreements. We also remain focused on progressingour investment priorities across the existing portfolio, including key infrastructure and commercial initiatives designed to enhance capacity,improve the passenger experience and strengthen our platform over the long term.

Lookingahead, we are encouraged by the strength of traffic trends across our network, with solid demand continuing into the second quarter, particularlyin international markets. At the same time, we will continue to closely monitor geopolitical developments in the Middle East and any potentialimplications for traffic, airlines capacity and fuel supply. We remain focused on maintaining a healthy financial position, investingwith discipline and executing our strategy to drive sustainable value creation.**”

1Q26 Operating Performance

Passenger Traffic

Total passenger traffic increased by 7.0% YoY to 21.8 million passengers, mainly supported by growth in the international segment. Domestic traffic remained largely flat, increasing by 0.1% YoY, with positive contributions from Brazil and Ecuador, offset by declines in Argentina and Italy. International traffic expanded by 13.7% YoY, with all countries of operation posting positive YoY growth, including double-digit increases in Argentina, Italy, and Ecuador. Notably, Argentina accounted for over 70% of the YoY increase in international traffic during the quarter.

In Argentina, passenger traffic increased by 5.5% YoY, driven by double-digit growth in international traffic, partially offset by a slight decline in the domestic segment, and negatively impacted by a nationwide 24-hour strike organized by major labor unions on February 19. Domestic traffic declined by 1.6% YoY, reflecting reduced capacity from Flybondi and Aerolíneas Argentinas, which faced temporary fleet constraints due to engine issues affecting several aircraft. Bariloche, Córdoba, Iguazú and Mendoza ranked among the top summer destinations. International passenger traffic increased by 18.5% YoY, supported by temporary summer routes such as Ezeiza–Florianópolis operated by LATAM and Mendoza–Rio de Janeiro operated by GOL. Aerolíneas Argentinas also launched additional seasonal routes, including Tucumán–Florianópolis, Salta–Florianópolis, Buenos Aires (AEP)–Cabo Frio, and Córdoba–Aruba, among others. During the Carnival period, traffic increased by 27% compared to 2025, with Brazil, Chile, and the United States ranking as the top three destinations in February.

In Italy, passenger traffic increased by 7.1% YoY, primarily driven by strong performance in the international segment, which accounted for nearly 80% of total traffic and increased by 10.3% YoY. International growth was supported by increases of 10.8% at Florence Airport and 9.8% at Pisa Airport. Domestic traffic declined by 2.6% YoY, mainly attributable to lower activity at Florence Airport. Adverse weather conditions in January led to flight cancellations and diversions.

In Brazil, total passenger traffic increased by 12.1% YoY, reflecting improved operating conditions following prior constraints in the country’s aviation sector. Domestic traffic, which accounted for over 50% of total traffic, grew by 5.7% YoY, while transit passengers increased by 21.8% YoY. International traffic, representing approximately 6% of the mix, rose by 7.7% YoY, contributing positively to overall performance. Growth was also supported by a post-Carnival rebound in corporate demand, with Brasília benefiting from its role as a key secondary hub within the domestic network.

In Uruguay, where traffic is predominantly international, total passenger traffic increased by 3.5% YoY, supported by additional flight frequencies to accommodate strong summer-season demand. Among other developments, GOL launched a new Montevideo–Fortaleza route and resumed its São Paulo–Punta del Este and Buenos Aires–Punta del Este services for the summer season. Aerolíneas Argentinas also increased frequencies on its Buenos Aires–Punta del Este route and introduced a new Córdoba–Punta del Este service, while Azul launched a new Montevideo–Belo Horizonte route, operating two weekly frequencies.

In Armenia, passenger traffic increased by 8.5% YoY, driven by the addition of new airlines and routes, as well as increased frequencies. Notably, in October 2025, Wizz Air established a new base at Yerevan’s Zvartnots Airport, deploying two aircraft and launching ten new direct routes to Europe. March performance was partially impacted by disruptions related to the conflict in Iran, which led to flight cancellations and airspace restrictions across the region; however, the impact was limited.

In Ecuador, passenger traffic increased by 7.2% YoY despite ongoing public security concerns. International traffic increased by 10.6% YoY, mainly supported by higher frequencies to the United States, primarily New York, from key airlines such as American Airlines, Avianca and LATAM. Routes to Europe also contributed to international traffic growth. Domestic traffic rose by 4.8% YoY, although high airfares continued to weigh on demand.

Cargo Volume

Cargo volume increased by 1.7% YoY, mainly driven by YoY increases in Argentina and Armenia, partially offset with reductions in Italy, Uruguay, Ecuador and Brazil. Performance by country was as follows: Armenia (+26.2%), Argentina (+2.9%), Brazil (-0.9%), Ecuador (-6.8%), Uruguay (-10.1%), and Italy (-20.0%). Argentina, Brazil, and Armenia accounted for 80% of total cargo volume in the quarter.

Aircraft Movements

Total aircraft movements increased by 3.5% YoY, with positive YoY contributions from all countries of operations, except Ecuador: Italy (+6.9%), Brazil (+6.2%), Armenia (+4.8%), Uruguay (+4.7%), Argentina (+3.2%), and Ecuador (-2.9%). Argentina, Brazil, and Ecuador accounted for over 80% of total aircraft movements in the quarter.

Review of ConsolidatedResults

Results for ECOGAL, which operates the Galapagos Airport in Ecuador, are accounted for under the equity method.

Revenues

Consolidated revenues increased by 20.1% YoY to $537.6 million. Excluding Construction Services and the impact of IAS 29, revenues rose 15.5% YoY to $477.9 million, outpacing the 7.0% growth in passenger traffic. This solid performance was supported by positive contributions across all countries of operations, with Argentina, Armenia, Brazil, Uruguay and Italy delivering double-digit revenue growth. Both commercial and aeronautical revenues contributed to the increase. Revenue growth was further supported by the appreciation of local currencies.

The following table provides a breakdown of revenue performance by country. Further details on the performance of CAAP´s countries of operations can be found on page 11.

AeronauticalRevenues accounted for 51.7% of total revenues, increasing by 17.4% YoY to $277.8 million, or by 13.8% YoY to $267.7 million excluding the impact of IAS 29. This performance was supported by a 7.0% increase in passenger traffic, with positive contributions from all countries of operations, including double-digit growth in Brazil, Argentina, Armenia, Uruguay and Italy. Argentina was the main contributor, with aeronautical revenues increasing by 17.7% YoY, or by 12.2% YoY ex-IAS 29, primarily reflecting 18.5% growth in international traffic. Brazil, Italy, Armenia and Uruguay delivered strong revenue performance, with aeronautical revenues increasing by 33.6%, 22.5%, 18.2% and 12.7%, respectively, in line with passenger traffic growth. Meanwhile, Ecuador reported an increase of 9.5%, also in line with passenger traffic growth. Tariff increases in Brazil, Uruguay and Ecuador also supported aeronautical revenue growth.

Non-AeronauticalRevenues accounted for 48.3% of total revenues, increasing by 23.1% YoY to $259.8 million, or by 19.9% YoY to $252.9 million excluding the impact of IAS 29. Commercial revenues rose by 21.0% YoY, or 18.0% ex-IAS 29, primarily driven by strong contributions from fuel-related revenues (mainly in Armenia), cargo revenues, as well as improved performance in VIP lounges, food and beverage, duty-free, parking facilities, and other passenger-related revenue streams. Growth in advertising and space rentals also supported this performance. Meanwhile, construction service revenue increased by 37.2% YoY, or 32.1% ex-IAS 29, mainly reflecting higher capital expenditure levels in most countries during the period.

Operating Costs and Expenses

In 1Q26, Total costs and expenses, excluding construction service costs, increased by 13.4% YoY, or 11.3% to $320.4 million when excluding the impact of IAS 29. This increase, which remained below the pace of revenue growth, was primarily driven by increased Fuel costs in Armenia, along with higher Concession fees and Salaries and social security contributions, mainly in Argentina. Higher SG&A expenses also contributed to the overall cost increase.

Costof Services rose by 16.4% YoY, or 14.4% to $297.2 million when ex-IAS29, mainly as a result of the following increases:

§ 41.5%, or $11.9 million, in Construction Service Costs, reflecting higher<br>capital expenditures,
§ 60.0%, or $11.0 million, in Fuel costs, mainly in Armenia,
--- ---
§ 14.2%, or $7.9 million, in Concession fees, primarily in Argentina,<br>and
--- ---
§ 12.1%, or $7.7 million, in Salaries and social security contributions.
--- ---

These increases were partially offset by a decline of 7.0% in Office expenses. Excluding Construction Service Costs, Cost of Services increased by 13.6% YoY, or by 11.6% to $256.4 million when excluding the impact of IAS 29, primarily due to the aforementioned increases in Fuel Costs, Concession Fees, and Salaries.

Selling,General, and Administrative Expenses (“SG&A”) increased by 19.2% YoY to $64.8 million in 1Q26. Excluding the impact of IAS 29, SG&A expenses rose by 16.8% YoY to $62.0 million, mainly reflecting higher Salaries and social security contributions, as well as increased Services and fees and Taxes.

Otherexpenses decreased to $2.0 million in 1Q26, from $5.1 million in 1Q25.

Adjusted EBITDA and Adjusted EBITDA excluding ConstructionService

In 1Q26, CAAP reported Adjusted EBITDA of $198.0 million and Adjusted EBITDA ex-IFRIC 12 of $196.2 million, up 26.1% from $155.6 million in 1Q25. Excluding the impact of IAS 29 in Argentina, Adjusted EBITDA ex-IFRIC 12 increased by 18.7% year-over-year to $187.4 million.

This strong performance was primarily driven by a 27.5% year-over-year increase in Argentina (or 16.0% ex-IAS 29), supported by robust revenue growth on the back of solid international travel performance, combined with effective cost controls. Results were also supported by double-digit Adjusted EBITDA ex-IFRIC 12 growth in Brazil, Armenia, Ecuador and Uruguay, along with a modest increase in Italy.

Adjusted EBITDA margin ex-IFRIC 12 expanded by 2.3 percentage points to 39.6%, compared to 37.3% in 1Q25. Excluding the impact of IAS 29 in Argentina, the Adjusted EBITDA margin ex-IFRIC 12 expanded by 1.0 percentage point, from 38.2% in 1Q25 to 39.2% in 1Q26, with margin expansion across all countries of operations except Armenia and Italy. Armenia's margin contraction primarily reflected a greater contribution from the fuel business, which carries structurally lower margins than core airport operations, resulting in a dilution effect on the overall margin.

Financial Income and Loss

CAAP reported a Net financialloss of $10.5 million in 1Q26, compared with a net financial loss of $34.9 million in 1Q25. The positive YoY result was primarily driven by higher foreign exchange gains in Argentina, reflecting the impact of a real appreciation of the Argentine peso on the net monetary liability position, together with lower net interest expenses. Excluding the application of IAS 29, CAAP reported a net financial loss of $42.5 million in 1Q26, compared with a loss of $65.0 million in the same period last year.

Income Tax Expense

During 1Q26, the Company reported an Income Tax Expense of $47.9 million, compared to an expense of $32.4 million in 1Q25. Excluding the impact of IAS 29, income tax expense totaled $30.7 million in 1Q26, compared to $19.0 million in the year-ago quarter.

Net Income and Net Income Attributable to Ownersof the Parent

During 1Q26, CAAP reported netincome of $80.4 million, compared to $36.2 million in 1Q25. The increase was primarily driven by a 34.0% year-over-year rise in operating income, along with higher foreign exchange gains on the net monetary liability position in Argentina, as well as lower net interest expenses, partially offset by higher Income tax expense.

In 1Q26, the Company reported Net Income Attributed to Owners of the Parent of $77.1 million and earnings per common share of $0.47, compared with Net Income Attributable to Owners of the Parent of $40.8 million in 1Q25, equivalent to earnings per common share of $0.25.

Consolidated Financial Position

As of March 31, 2026, Cash and cash equivalents totaled $666.2 million, increasing 12.4% from the $592.8 million reported as of December 31, 2025. Total liquidity, which includes cash and cash equivalents as well as other current financial assets, increased to $772.4 million, up from $714.8 million as of December 31, 2025.

Total debt declined 0.9%, or $9.9 million, to $1,085.3 million as of March 31, 2026, compared with $1,095.2 million as of December 31, 2025, primarily reflecting debt repayments in Argentina. A total of $779.8 million, or 71.9% of total debt is denominated in U.S. dollars, while $174.6 million, or 16.1% is denominated in Brazilian Reals, and $130.9 million, or 12.1%, is in Euros.

The Net Debt to LTM Adjusted EBITDA ratio improved to 0.5x as of March 31, 2026, from 0.7x as of December 31, 2025. This reduction reflected lower net debt, driven by gross debt repayments and increased cash balances, as well as higher LTM Adjusted EBITDA. No impairments to intangible assets were recorded over the past twelve months. As a result, the net debt to LTM Adjusted EBITDA ratio excluding intangible assets also stood at 0.5x. All CAAP subsidiaries remained in full compliance with their financial covenants as of March 31, 2026.

PassengerTraffic passenger traffic increased by 5.5% YoY, driven by double-digit growth in international traffic, partially offset by a slight decline in the domestic segment, and negatively impacted by a nationwide 24-hour strike organized by major labor unions on February 19. Domestic traffic declined by 1.6% YoY, reflecting reduced capacity from Flybondi and Aerolíneas Argentinas, which faced temporary fleet constraints due to engine issues affecting several aircraft. Bariloche, Córdoba, Iguazú and Mendoza ranked among the top summer destinations. International passenger traffic increased by 18.5% YoY, supported by temporary summer routes such as Ezeiza–Florianópolis operated by LATAM and Mendoza–Rio de Janeiro operated by GOL. Aerolíneas Argentinas also launched additional seasonal routes, including Tucumán–Florianópolis, Salta–Florianópolis, Buenos Aires (AEP)–Cabo Frio, and Córdoba–Aruba, among others. During the Carnival period, traffic increased by 27% compared to Carnival 2025, with Brazil, Chile, and the United States ranking as the top three destinations in February.

In Uruguay, where air traffic is primarily international, total passenger traffic increased by 3.5% YoY, supported by additional flight frequencies to accommodate strong summer-season demand. Among other developments, GOL launched a new Montevideo–Fortaleza route and resumed its São Paulo–Punta del Este and Buenos Aires–Punta del Este services for the summer season. Aerolíneas Argentinas also increased frequencies on its Buenos Aires–Punta del Este route and introduced a new Córdoba–Punta del Este service, while Azul launched a new Montevideo–Belo Horizonte route, operating two weekly frequencies.

Revenues increased by 25.1% YoY to $64.1 million on a reported basis, well above passenger traffic growth. Excluding Construction Service revenues, revenues increased 15.2% to $53.8 million, primarily driven by higher commercial activity and increased aeronautical revenues tied to YoY passenger growth.

· Aeronautical Revenues increased 12.7% YoY, or $3.3 million, to $29.1 million, aligned with<br>the increase in passenger traffic and tariff increases.
· Commercial Revenues increased by 18.3% YoY, or $3.8 million, to $24.7 million, primarily driven<br>by higher cargo revenues, which benefited from tariff increases and higher import volumes, particularly in courier services. Passenger-related<br>revenues, especially from VIP lounges, duty-free, and parking facilities, also contributed to commercial revenue growth, outpacing overall<br>traffic growth.

TotalCosts and Expenses increased by 31.3% YoY to $40.2 million. Excluding Construction service, total Costs and expenses rose by 14.7% YoY to $29.9 million, reflecting higher Cost of services and SG&A expenses. Costs in U.S. dollars were also impacted by the 9.0% average YoY appreciation of the Uruguayan peso.

· Cost of Services increased by 37.1% YoY to $33.2 million. Excluding Construction Service costs,<br> Cost of Services grew by 16.3% to $22.9 million, mainly driven by higher Salaries and social<br> security contributions, Maintenance expenses and Concession fees.
· SG&A expenses increased 9.0% YoY, to $6.9 million, principally due to higher Services and fees<br>and Maintenance expenses.
--- ---

AdjustedSegment EBITDA increased by 15.8% YoY to $26.4 million, while the Adjusted EBITDA margin, excluding IFRIC 12, expanded by 0.2 percentage points to 49.0%. The slight margin expansion primarily reflected solid top-line growth driven by YoY traffic increases, partially offset by higher Salaries and maintenance expenses, which were impacted by the 9.0% YoY average appreciation of the Uruguayan peso on the local currency-denominated cost base.

During 1Q26, CAAP made Capital Expenditures of $11.3 million in Uruguay, up from $7.0 million in 1Q25.

Passenger traffic in Armenia increased by 8.5% YoY, driven by the addition of new airlines and routes, as well as increased frequencies. Notably, in October 2025, Wizz Air established a new base at Yerevan’s Zvartnots Airport, deploying two aircraft and launching ten new direct routes to Europe. March performance was partially impacted by disruptions related to the conflict in Iran, which led to flight cancellations and airspace restrictions across the region; however, the impact was limited.

Revenues increased by 40.0% YoY to $67.4 million on an ‘as reported’ basis, or by 38.8% when excluding Construction Service revenues, driven by growth in both Commercial and Aeronautical revenues, underpinned by higher traffic volumes. Results also benefited from the 11.2% YoY average appreciation of the euro.

· Aeronautical Revenues increased by 18.2% YoY, or $3.2 million, to $20.6 million, above traffic<br>growth.
· Commercial Revenues increased by 50.8% YoY, or $15.1 million, to $44.9 million, largely driven<br>by higher fuel revenues, which are directly linked to fuel costs, as well as growth in VIP lounges, duty-free sales and other passenger-related<br>revenues. Cargo revenues also contributed to commercial revenue growth.
--- ---

TotalCosts and Expenses increased by 32.2% YoY to $47.0 million. Excluding IFRIC 12, Total Costs and Expenses increased by 30.9% YoY, largely driven by higher Cost of Services.

· Cost of Services increased by 35.1% YoY to $41.0 million. Excluding IFRIC 12, Cost of Services<br>increased by 33.6%, mainly driven by higher fuel costs, in line with the increase in fuel-related revenues.
Page **19** of  **34**
· SG&A increased 21.4% YoY, or $1.0 million, to $5.6 million in 1Q26, primarily reflecting higher<br>Salaries and social security contributions, Taxes and Maintenance expenses.

AdjustedSegment EBITDA increased by 35.0% YoY to $24.5 million in 1Q26, supported by volume-driven operating leverage and higher passenger traffic. The Adjusted EBITDA margin, excluding IFRIC 12, contracted 1.4 percentage points to 37.0%, primarily reflecting a greater contribution from the fuel business. While the fuel segment continued to grow in line with increased activity levels, it carries structurally lower margins than the core airport operations, resulting in a dilution effect on the overall margin.

During 1Q26, CAAP made Capital Expenditures of $3.9 million in Armenia, compared to $2.7 million in 1Q25.

In Ecuador, passenger traffic increased by 7.2% YoY despite ongoing public security concerns. International traffic increased by 10.6% YoY, mainly supported by higher frequencies to the United States, primarily New York, from key airlines such as American Airlines, Avianca and LATAM. Routes to Europe also contributed to international traffic growth. Domestic traffic rose by 4.8% YoY, although high airfares continued to weigh on demand.

Revenues increased by 9.8% YoY to $29.9 million in 1Q26 on an ‘As reported’ basis, driven by both higher Commercial and Aeronautical revenues.

Key Quarter Highlightsand Subsequent Events

CAAP | Annual General Shareholders Meeting

On May 13, 2026, Corporación América Airports held its annual general meeting of shareholders in Luxembourg. The Company’s shareholders

approved and adopted all matters submitted to them at the Meeting.

For further information on subsequent events, please refer to Note 20 of the Company’s Financial Statements, filed with the SEC on Form 6-K.

Hyperinflation Accountingin Argentina

Following the categorization of Argentina as a country with a three-year cumulative inflation rate greater than 100%, the country is considered highly inflationary in accordance with IFRS. Consequently, starting July 1, 2018, the Company reports results of its Argentinean subsidiaries applying IFRS rule IAS 29. IAS 29 requires that results of operations in hyperinflationary economies are reported as if these economies were highly inflationary as of January 1, 2018, and thus year-to-date results should be restated adjusting for the change in general purchasing power of the local currency, using official indices, before converting the local amounts at the closing rate of the period (i.e. December 31, 2019 closing rate for 2019 results). For comparison purposes, the impact of adopting IAS 29 in Aeropuertos Argentina 2000 (“AA2000”), the Company’s largest subsidiary in Argentina, which accounted for over 95% of passenger traffic, revenues and Adjusted EBITDA, respectively, of the Argentina segment in 1Q26, is presented separately in each of the applicable sections of this earnings release, in a column denominated “IAS 29”.

Non-Financial Disclosure

With the assistance of an external advisor and under guidance of the Board of Directors, the Company is preparing its ESG policy and gearing up to make the necessary disclosure under the Corporate Sustainability Reporting Directive in a timely manner.

Use of Non-IFRS FinancialMeasures

This announcement includes certain references to Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted EBITDA excluding Construction Service and Adjusted EBITDA Margin excluding Construction service, as well as Net Debt:

AdjustedEBITDA is defined as income for the period before financial income, financial loss, income tax expense, depreciation and amortization.

AdjustedEBITDA Margin is calculated by dividing Adjusted EBITDA by total revenues.

**AdjustedEBITDA excluding Construction Service (“**Adjusted EBITDA ex-IFRIC”) is defined as income for the period before construction services revenue and cost, financial income, financial loss, income tax expense, depreciation and amortization.

**AdjustedEBITDA Margin excluding Construction Service (“**Adjusted EBITDA Margin ex-IFRIC12”) excludes the effect of IFRIC 12 with respect to the construction or improvements to assets under the concession and is calculated by dividing Adjusted EBITDA excluding Construction Service revenue and cost, by total revenues less Construction service revenue.

Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted EBITDA excluding Construction Service and Adjusted EBITDA Margin excluding Construction Service are not measures recognized under IFRS and should not be considered as an alternative to, or more meaningful than, consolidated net income for the year as determined in accordance with IFRS or as indicators of our operating performance from continuing operations. Accordingly, readers are cautioned not to place undue reliance on this information and should note that these measures as calculated by the Company, may differ materially from similarly titled measures reported by other companies. We believe that the presentation of Adjusted EBITDA and Adjusted EBITDA excluding Construction Service enhances an investor’s understanding of our performance and are useful for investors to assess our operating performance by excluding certain items that we believe are not representative of our core business. In addition, Adjusted EBITDA and Adjusted EBITDA excluding Construction Service are useful because they allow us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods, capital structure or income taxes and construction services (when applicable).

Page **22** of  **34**

Netdebt is calculated by deducting “Cash and cash equivalents” from total financial debt.

Figuresex-IAS 29 result from dividing nominal Argentine pesos for the Argentine Segment, by the average foreign exchange rate of the Argentine Peso against the US dollar in the period. Percentage variations ex-IAS 29 figures compare results as presented in the prior year quarter before IAS 29 came into effect, against ex-IAS 29 results for this quarter as described above. For comparison purposes, the impact of adopting IAS 29 in Aeropuertos Argentina 2000, the Company’s largest subsidiary in Argentina, is presented separately in each of the applicable sections of this earnings release, in a column denominated “IAS 29”. The impact from “Hyperinflation Accounting in Argentina” is described in more detail page 22 of this report.

Definitions and Concepts

CommercialRevenues: CAAP derives commercial revenue principally from fees resulting from warehouse usage (which includes cargo storage, stowage and warehouse services and related international cargo services), services and retail stores, duty free shops, car parking facilities, catering, hangar services, food and beverage services, retail stores, including royalties collected from retailers’ revenue, and rent of space, advertising, fuel, airport counters, VIP lounges and fees collected from other miscellaneous sources, such as telecommunications, car rentals and passenger services.

ConstructionService revenue and cost: Investments related to improvements and upgrades to be performed in connection with concession agreements are treated under the intangible asset model established by IFRIC 12. As a result, all expenditures associated with investments required by the concession agreements are treated as revenue generating activities given that they ultimately provide future benefits, and subsequent improvements and upgrades made to the concession are recognized as intangible assets based on the principles of IFRIC 12. The revenue and expense are recognized as profit or loss when the expenditures are performed. The cost for such additions and improvements to concession assets is based on actual costs incurred by CAAP in the execution of the additions or improvements, considering the investment requirements in the concession agreements. Through bidding processes, the Company contracts third parties to carry out such construction or improvement services. The amount of revenues for these services is equal to the amount of costs incurred plus a reasonable margin, which is estimated at an average of 3.0% to 5.0%.
