1Q26 Highlights

Message from the CFO

“During the first quarter of the year, BBVA Argentina’s business model demonstrated resilience in an operating environment that continues to be challenging. The Bank recorded a net income of $85.2 billion, representing a 31.2% increase compared to the previous quarter and an 8.3% quarterly ROE, reflecting the institution’s ability to generate value in transitional contexts.

In a quarter in which commercial activity within the financial system declined slightly, in line with market trends and the seasonality of the quarter, BBVA Argentina managed to maintain its market share gain trend up to 12.15%, even after a very strong end to 2025, mainly driven by demand for commercial loans.

This progress is consistent with our strategic determination to play a leading role in the Argentine financial system and to lead credit supply as the cycle normalizes.

During the quarter, volatility in interest rates declined, while rates maintained the downward trend that began following the midterm elections. The Central Bank continued unraveling the prudential measures implemented in the third quarter of last year and began successfully executing the reserve purchase plan announced last December.

Likewise, the government continued advancing its structural economic reform plan, managing to approve important initiatives such as the Labor Reform, the amendment to the Glacier Law, and the 2026 Budget. The Incentive Regime for Large Investments (RIGI) continued attracting investment projects, and a second phase has recently been announced focusing on productive sectors with little or no presence in the country.

The trade balance for the first quarter reached USD 5.5 billion, multiplying by five the balance from the previous year, with record exports in the energy sector. At the same time, Argentine companies and provinces have secured financing in international capital markets exceeding USD 10 billion in recent months. Fitch recently announced an upgrade to the country’s sovereign rating. All of this has occurred in a context of fiscal and monetary discipline, while April inflation data once again showed signs of deceleration.

This evolution allows us to remain optimistic regarding the potential path of credit recovery in the coming quarters and a reversal in the trend of credit quality indicators that have affected both the Bank and the financial system during recent quarters.

The positive evolution of the Bank’s results, even in a quarter in which inflation was higher, responds both to the strong performance of revenues and to the control of recurring expenses and improved cost of risk performance, which, although still at elevated levels, reflects a reduction compared to the previous quarter.

Net interest income increased by 5.9%, supported by the faster decline in funding costs in a context of falling interest rates and by efficient management of origination pricing. Fees maintained positive performance even in a quarter of lower activity, while expenses, net of non-recurring impacts, declined slightly during the period.

Regarding asset quality, although BBVA's non-performing loan ratio continued to rise to 5.6%, this growth was lower than what occurred at the systemic level, and this value remains among the lowest in the financial system. In this regard, we understand that the precautionary measures and strict origination criteria implemented by the Bank would allow for a normalization trend to begin in the coming quarters.

BBVA Argentina currently has the necessary tools to lead the market, supported by robust liquidity and capital levels. The Common Equity Tier 1 capital ratio stands at 18.8%, placing it at appropriate levels to sustain our growth strategy. Within this framework of strength, the Shareholders’ Meeting approved a dividend distribution of $63,057 million (at December 2025 values), which would become effective starting in June.

Within this framework of strength, BBVA Argentina has all the necessary tools to lead the market. In light of the context of fiscal and monetary discipline and the potential path of credit recovery in the coming quarters, we move forward with optimism and determination to consolidate our role and lead credit supply in the Argentine financial system ”

	1Q26 Earnings Release	p.4

Quarterly Results

As of 1Q26, BBVA Argentina achieved a net income of $85.2 billion, representing an increase of 31.2% for the quarter and a decrease of 21.2% versus 1Q25. The ROE for the quarter reached 8.3%, and the ROA 1.2%.

The 31.2% increase in the quarter's results is mainly explained by higher operating income, with expenses remaining stable overall. The increase in income is explained by (i) lower loan loss allowances, (ii) better net interest income, and (iii) improvements in fee income.

While net interest income benefited from the lower rate environment, with deposits renewing at higher rates faster than assets; fees continued the positive trend started several quarters ago.

The reduction in loan loss allowances is explained both by (i) the strengthening of origination and restructuring policies that have allowed the reinforcement of customers' credit profiles, and (ii) by improvements in the ratings of certain commercial groups.

Although personnel expenses increased 25.1% in the quarter, excluding non-recurring factors, they would have fallen slightly in the period of analysis. The item of Other operating expenses fell by 17.2%, mainly reflecting the lower impact of the turnover tax, due to lower activity and lower rates. Lower charges from results from initial loss of loans below market rate were also observed there, as a result of the lower seasonality of credit card promotions in the first quarter, compared to the fourth quarter of each year.

Net income from the net monetary position was 26.8% higher QoQ, in a context of increasing inflation (9.44% versus 7.86% in 4Q251).

	1Q26 Earnings Release	p.5

It is important to mention that the incorporation of FCA Compañía Financiera was made at a balance sheet level on December 31, 2025, but not in the income statement. As of January 2026, FCA consolidates line by line, the same way as VWFS and PSA do.

The Other Comprehensive Income (OCI) line totaled a gain of $59.9 billion in 1Q26, resulting from the improvement in the valuation of financial instruments at fair value (FV) with changes in OCI.

	1Q26 Earnings Release	p.6

Net Interest Income

Net interest income for 1Q26 amounted to $879.9 billion, an increase of 5.9% compared to 4Q25 and 22.6% compared to 1Q25. In 1Q26, interest income decreased to a lesser extent than expenses, in monetary and percentage terms.

The downward trend in interest rates (the average TAMAR rate recorded a 640 bps decrease compared to 4Q25, reaching 31.9%) allowed interest expenses to continue decreasing at a faster pace than income, due to the shorter average life of liabilities.

On the other hand, income with UVA adjustment began to reflect the increase in higher inflation rates in recent months, growing 17.5% in the period. The CER index accrued by products with this adjustment is recorded with a certain lag. 52% of interest income from CER/UVA adjustments is explained by the interest generated by CPI-linked securities, while 48% is explained by loans.

Interest income from loans decreased by 12.6% QoQ to $1.1trillion, affected by the drop in the average TAMAR rate, impacting short-term products.

Income from government securities fell 18.2% in 1Q26, with 96% of income coming from fair value through OCI (Other Comprehensive Income) securities.

	1Q26 Earnings Release	p.7

Interest expenses totaled $648.8 billion, falling 26.8% in 1Q26 (due to lower expenses from time deposits and current accounts). Interest on time deposits (73.0% of total expenses) fell 28.3%.

NIM

In 1Q26, the total net interest margin (NIM) was 18.6%, higher than the 17.5% of 4Q25 and below the 19.2% of 1Q25. While the NIM in pesos increased 210 bps to 22.3% due to a higher speed in the reduction of passive rates, the NIM in dollars fell 110 bps to 4.1% due to increased competition for loans in foreign currency.

The quarter again showed a greater weight of dollar-earning assets in the mix.

As highlighted in the graphs accompanying the first section of this document, the NIM net of the net result from the monetary position has remained relatively stable over the last quarters.

	1Q26 Earnings Release	p.8

	1Q26 Earnings Release	p.9

Net Fee Income

Net fee income in 1Q26 totaled $169.8 billion, an increase of 16.9% compared to 4Q25 and 28.3% compared to 1Q25. Although this figure includes some positive one-off impacts in the quarter, it is important to note that, even without these effects, the evolution would have been slightly positive. This, in a quarter with low seasonality due to lower commercial activity, reinforces the growth process that the entity has been showing in this line item for several quarters.

Net Income from Measurement of Financial Instruments at Fair Value and Foreign Exchange and Gold Gains/Losses

In 1Q26, the net income from the measurement of financial instruments valued at fair value with changes in results was $21.2 billion, increasing 136.0% mainly due to larger trading positions and the positive evolution of sovereign bond prices.

The total result of foreign currency exchange difference generated a gain of $53.3 billion in 1Q26, decreasing by 12.8% in the quarter.

	1Q26 Earnings Release	p.10

The quarterly drop in exchange difference is mainly explained by a lower volume of buying and selling activity, compared to a fourth quarter with greater hedging activity prior to the mid-term elections, and also partly, by the 5.5% appreciation of the Argentine peso.

Other Operating Income

In 1Q26, the other operating income line totaled $65.6 billion, falling 27.2% QoQ, and increasing 27.5% YoY. The lower result in recovered loans is explained by higher income in 4Q25, related to a significant recovery with a commercial portfolio client.

	1Q26 Earnings Release	p.11

Operating Expenses

Personnel Benefits & Administrative Expenses

In 1Q26, personnel benefits and administrative expenses totaled $352.8 billion, increasing 14.6% QoQ, and falling slightly 0.5% YoY in real terms.

Regarding personnel benefits, although an increase of 25.1% is observed, this figure incorporates non-recurring expenses for severance payments. Excluding these expenses, and neutralizing other specific and seasonal effects of the fourth quarter, expenses would have experienced a slight decrease in real terms.

Administrative expenses rose 4.7% in 1Q26, mainly in the lines of rent, software, and commercial reports, the first two associated with expenses related to the parent company, which had a greater seasonal impact in the first quarter. This was offset by a decrease in the document distribution line. In general terms, expenses are expected to reflect a favorable behavior throughout the year, associated with the efficiency and expense control measures that the Bank is implementing The quarterly efficiency ratio for 1Q26 was 51.4%, above the 45.9% of 4Q25 and below the 56.3% registered in 1Q25.

	1Q26 Earnings Release	p.12

The quarterly deterioration is explained both by the aforementioned increase in expenses and the greater loss from the net monetary position in the quarter.

Other Operating Expenses

In 1Q26, other operating expenses totaled $202.9 billion, decreasing 17.2% QoQ, and increasing 13.0% versus 1Q25.

The quarter was marked by a decrease in (i) turnover tax, followed by (ii) result from initial loss of loans below market rate, and (iii) other operating expenses. In the case of turnover tax, the drop is explained by lower interest rates and credit activity, while the result from initial loss of loans below market rate is linked to a more restrictive origination policy regarding installment promotions, in part with a certain seasonal component. With respect to other operating expenses, this line includes provisions made for uncollectible package fees, which decreased during the quarter.

Income from Associates

The income from associates line item shows the results of unconsolidated companies. During 1Q26, a loss of 3.8 billion was recorded, mainly due to the Bank's shareholding in BBVA Seguros Argentina S.A., Rombo Compañía Financiera S.A., Interbanking S.A., Play Digital S.A., and Openpay Argentina S.A.

Income Tax

The accumulated income tax of three months of 2026 showed a loss of $48.3 billion.

The accumulated effective tax rate of three months of 2026 was 35%2, while in 2025 it was 38% .

2 Income tax, in accordance with IAS No. 34, is recognized in interim periods based on the best estimate of the weighted average tax rate that the Entity expects for the year.

	1Q26 Earnings Release	p.13

Balance Sheet and Activity

Loans and other financing

As of 1Q26, the private loan portfolio totaled $11.7 trillion, a decrease of 3.5% in the quarter, and an increase of 18.6% versus 4Q25. It is worth mentioning that the consolidation with FCA is not incorporated in 1Q25.

	1Q26 Earnings Release	p.14

In a quarter marked by low seasonality, the drop in private loans is generated primarily in short-term commercial loans in pesos, such as (i) documents, (ii) overdrafts, and (iii) other loans (financial and floorplan).

As a consequence of the context, individual portfolios in consumer products (credit cards and personal loans) also did not gain traction. We highlight the continuous momentum of pledge and mortgage loans, which continue to gain ground within the retail portfolio, as a consequence of the financial stability and good credit performance that these products have been demonstrating. This creates better conditions for our customers to make long-term investment decisions.

In summary, the local currency private loan portfolio fell 6.5% in the quarter, partially offset by a 6.8% rise in foreign currency private loans. It is noteworthy that the latter denominated in U.S. dollars, mainly commercial, grew 23.3% in the period and 73.6% in the last 12 months.

In nominal terms, BBVA Argentina's retail, commercial, and total loan portfolios increased by 9.1%, 3.1%, and 5.3% respectively during the quarter, below the inflation level in all cases.

La participación de préstamos totales sobre activo es de 59%, versus 57% en el 4T25 y 56% en el 1T25.

	1Q26 Earnings Release	p.15

Asset Quality

In 1Q26, the NPL ratio (non-performing loans / total loans) increased from 4.18% to 5.60%, mainly focused on the retail non-performing loan portfolio in credit cards and personal loans, in line with the systemic context. Commercial delinquency maintained a good performance, with a slight increase of 14 bps mainly due to small companies.

The coverage ratio (provisions / non-performing loans) reached 88.41% in 1T26. Despite the increase in non-performing loans, the bank continues to show an adequate level of provisions to cope with insolvencies.

The quarterly cost of risk (loan loss allowances / average total loans) reached 6.14% in 1Q26, compared to 8.11% in 4Q25. The drop is related to (i) lower origination, (ii) strengthened origination and restructuring policies that have allowed the credit profile of customers to improve, and (iii) an improvement in the ratings of certain aforementioned commercial groups.

In annual accumulated terms, the cost of risk of 6.14% in 1Q26 compares to 4.40% in 1Q25.

Allowances for the Bank in 1Q26 reflect expected losses driven by the adoption of the IFRS 9 standards as of January 1, 2020, except for debt instruments issued by the nonfinancial government sector which were excluded from the scope of such standard.

	1Q26 Earnings Release	p.16

Public Sector Exposure

In 1T26, total public sector exposure, excluding exposure to the BCRA, totaled $4.2 trillion, falling 3.6% QoQ and increasing 12.8% YoY, with no relevant changes in the portfolio composition in the last three months.

Exposure to the public sector, excluding exposure to the BCRA (Central Bank of Argentina), represents 16.2% of total assets, above the 15.5% of 4Q25 and below the 17.1% of 1Q25.

	1Q26 Earnings Release	p.17

Deposits

During 1Q26, total deposits reached $17.5 trillion, a drop of 7.3% during the quarter, and an increase of 20.0% versus 1Q25.

Total deposits from the private sector in 1Q26 reached $16.7 trillion, showing a drop of 9.0% QoQ, and an increase of 15.7% YoY.

Los depósitos al sector privado no financiero en moneda extranjera expresados en pesos totalizaron $6.094.267 millones, cayendo 11,1% en el trimestre y aumentando 31,9% versus el 1T25. Esto se debe principalmente por una caída de caja de ahorro de 16,6%. Se destaca que los depósitos en moneda extranjera expresados en USD aumentaron 2,6% en el trimestre, denotando un efecto de la apreciación del peso argentino en las caídas mencionadas anteriormente.

Deposits from the non-financial private sector in pesos totaled $10.6 trillion, decreasing 7.8% QoQ and increasing 8.0% YoY. The quarterly variation is explained by (i) a decrease in time deposits of 6.7%, followed by (ii) a decrease of 16.8% in savings accounts, and (iii) a decrease of 8.6% in current accounts.

Deposits from the non-financial private sector in foreign currency, expressed in pesos, totaled $6.1 trillion, falling 11.1% QoQ and increasing 31.9% YoY. This is mainly due to a 16.6% drop in savings accounts. It is noteworthy that deposits in foreign currency expressed in U.S dollars increased 2.6% in the quarter, denoting an effect of the appreciation of the Argentine peso on the aforementioned decreases.

	1Q26 Earnings Release	p.18

In nominal terms, sight deposits fell 3.6%, time deposits rose 4.1%, and total deposits decreased 0.4%, not exceeding the period's inflation in any case.

As of 1Q26, the Bank's transactional deposits (current accounts and savings accounts) represented 41.7% of total private non-financial deposits, versus 45.6% in 4Q25 and 51.5% in 1Q25.
