I.MANAGEMENT’S DISCUSSION & ANALYSIS ON THE RESULTS OF THE OPERATION AND THE FINANCIAL SITUATION OF THE ISSUER, IN RELATION TO THE RESULTS REPORTED IN THE QUARTERLY FINANCIAL STATEMENTS

During the second quarter of 2025, Bancolombia’s loan portfolio continued its growth momentum. The most dynamic segment was mortgage lending, supported by the institution’s interest rate reduction strategy. Consumer lending also gained momentum, reversing a declining trend seen in previous quarters, with notable contributions from digital channels and key products such as credit cards and payroll loans. In contrast, commercial lending expanded at a more modest pace, although leasing showed a positive trend within this segment.

Funding sources showed broad-based expansion during the quarter, led by growth in savings accounts, followed by time deposits and checking accounts. Savings balances grew mainly in the retail segment, while the increase in time deposits reflected stronger demand for digital investment solutions. Corporate clients drove the improvement in checking accounts.

From a profitability standpoint, net income moderated compared to the previous quarter, mainly due to reduced non-recurring income associated with changes in the corporate structure. On the positive side, interest income continued to grow, supported by higher loan volumes across key segments and stable asset yields. Treasury operations contributed positively, benefiting from improved returns on investments. Interest expenses rose in line with a larger deposit base and funding cost dynamics. Provision expenses declined, reflecting healthier portfolio performance and stronger recoveries. Operating expenses increased, influenced by corporate restructuring efforts and tax-related impacts.

Bancolombia Consolidated

During the second quarter of 2025, Bancolombia’s Consolidated loan portfolio maintained its growth momentum. The most significant increase was seen in the mortgage portfolio, supported by the previously implemented interest rate reduction strategy. The consumer portfolio also showed a recovery, reversing the trend of the last three quarters, driven by the strong performance of both digital and traditional products such as Nequi, credit cards, and payroll loans. In contrast, the commercial portfolio posted more moderate growth, although leasing contributed positively within this segment.

On the funding side, there was broad-based expansion, led by higher balances in savings accounts, followed by time deposits and checking accounts. Savings growth was concentrated in the retail segment, while the increase in time deposits was linked to the strengthening of the digital channel. Checking accounts benefited from better performance in the corporate segment.

Net income for the quarter trended lower compared to the previous period, mainly due to lower revenues from dividends and equity method investments, as a result of adjustments in the corporate structure. Nevertheless, interest income continued to grow, supported by the recovery in the commercial portfolio, greater momentum in consumer lending, and a positive performance in mortgages. Treasury operations also had a positive contribution, leveraged on higher investment yields. At the same time, interest expenses increased due to higher funding costs, while provision expenses decreased, supported by an improvement in portfolio quality. Operating expenses rose, mainly due to costs related to the corporate reorganization and tax matters.

II.QUANTITATIVE AND QUALITATIVE ANALYSIS OF THE MARKET RISK TO WHICH THE ISSUER IS EXPOSED AS A RESULT OF ITS INVESTMENTS AND ACTIVITIES SENSITIVE TO MARKET VARIATIONS

Market risk refers to the possibility of incurring losses due to changes in equity prices, interest rates, exchange rates, and other indicators whose values are determined in public markets. It also encompasses the probability of unexpected changes in net interest income and the economic value of equity resulting from fluctuations in market interest rates.

The principles and guidelines for market risk management remain consistent with those disclosed as of December 31, 2024.

CONSOLIDATED

The analysis presented below for Grupo Cibest Consolidated is based on a comparison with the information reported by Grupo Bancolombia as of December 31, 2024.

Total market risk exposure of Bancolombia Consolidated decreased by 34.9%, from COP 1,697,566 millions in December 2024 to COP 1,105,473 millions in June 2025. This variation is mainly attributable to the creation of Grupo Cibest and its corporate reorganization process, which led to the exclusion of entities located outside Colombia from the consolidated financial statements. Regarding the main movements by risk factor, the most significant reduction was observed in the foreign exchange risk factor, due to lower exposure to U.S. dollar-denominated positions. Similarly, the collective investment funds and interest rate risk factors declined as a result of the new organizational structure. These effects were partially offset by an increase in Bancolombia’s portfolio, driven by higher exposure to private debt securities and foreign currency bonds.

Market risk exposure has remained within the approved appetite levels. It is subject to ongoing monitoring by Senior Management and serves as a key tool for decision-making aimed at preserving the stability of Bancolombia Consolidated.

Non-trading instruments market risk measurement

The relevant risk exposure in the banking book is interest rate risk, which refers to the probability of unexpected changes in net interest income or in the economic value of equity as a result of changes in market interest rates. Interest rate fluctuations affect the Bank’s income due to differences in the repricing of assets and liabilities.

Bancolombia Consolidated manage interest rate risk arising from banking activities in non-tradable instruments by analyzing interest rate mismatches between interest rate-sensitive assets and liabilities, and by estimating the impact on the net interest margin and the economic value of equity.

Foreign exchange exposures arising in the banking book are transferred to the treasury book for management.

Interest Risk Exposure (Banking Book)

Bancolombia Consolidated conduct interest rate risk sensitivity analysis by estimating the impact on the net interest margin of each position in the banking book using a repricing model and assuming a positive parallel shift of 100 basis points in interest rates.


17

The principles and guidelines for market risk management remain consistent with those disclosed as of December 31, 2024.

Sensitivity to Interest Rate Risk of the Banking Book

As of June 30, 2025, the net sensitivity of the banking book in local currency to a parallel shift of 100 basis points in interest rates was COP 349.574 billion, representing an increase of COP 2.326 billion compared to December 31,2024

Meanwhile, the sensitivity of the Net Interest Margin (NIM) in foreign currency to the same shift was USD 7.79 million, with an increase of USD 14.63 million between December 31,2024 and June 30, 2025.

These variations are mainly explained by the fact that the analysis for Bancolombia Consolidated is based on a comparison with the information reported by Grupo Bancolombia as of December 2024.

BANCOLOMBIA S.A

Market risk management at Bancolombia is the same as previously detailed, carried out for Bancolombia Consolidated.

Total market risk exposure decreased by 24.4% from COP 1,483,039 millions in December 2024 to COP 1,120,737 millions in June 2025. This variation is primarily explained by a lower exposure to the exchange rate risk factor, due to a reduction in positions denominated in U.S. dollars. Secondly, the stock price risk factor decreased as a result of the divestment of certain investments following the creation of Grupo Cibest. Conversely, the interest rate risk factor increased, driven by higher exposure to private debt securities and foreign currency bonds. Lastly, the collective investment funds risk factor also rose, explained by the appreciation of the Colombia Inmobiliario Fund.

During the period there have been no violations of the approved exposure limits and the market risk exposure is permanently monitored by Senior Management.

Interest Risk Exposure (Banking Book)

Bancolombia adopts the Interest Rate Risk in the Banking Book (IRRBB) guidelines established in Chapter XXXI – SIAR of Basic Accounting and Financial Circular Act 100 of 1995, Annex 15 Standard Methodology for determining IRRBB, applied to the assets, liabilities, and off-balance sheet positions indicated by the Superintendencia Financiera de Colombia.

Accordingly, a management framework for IRRBB has been designed, including Credit Spread Risk in the Banking Book (CSRBB), aimed at measuring its impact on delta EVE (Economic Value of Equity) and delta NII (Net Interest Income).

For the June reporting period, delta NII was COP 1.04 trillion, showing a reduction of COP 9,088 millions under a parallel downward scenario, considering the positive mismatch in repricing and capital maturities under one year. The observed reduction in delta NII between June and December is explained by the implementation of hedge accounting strategies, which increased liability sensitivity. This effect was further reinforced by the rise in fixed-rate CDTs with maturities under one year, helping to mitigate the impact of a potential decline in interest rates on NII.


18

Meanwhile, as of June 2025, delta EVE for Bancolombia was COP 2.01 trillion under a parallel upward scenario of market interest rate changes. delta EVE increased by COP 152,925 millions compared to December, mainly due to the growth in the mortgage portfolio and hedging swaps, which were offset by the increase in savings account balances.

III.MATERIAL VARIATIONS THAT HAVE OCCURRED IN THE RISKS TO WHICH THE ISSUER IS EXPOSED, OTHER THAN MARKET RISK, AND THE MECHANISMS IMPLEMENTED TO MITIGATE THEM

LIQUIDITY RISK

Liquidity risk refers to the possibility of being unable to efficiently and timely meet payment obligations—both expected and unexpected, current and future—without disrupting the normal course of daily operations or affecting the financial condition of the Bancolombia Consolidated. This risk arises when there is an insufficiency of available liquid assets or when it becomes necessary to incur unusual funding costs.

The principles and guidelines for liquidity risk management remain consistent with those disclosed as of December 31, 2024.

CONSOLIDATED

The following analysis for Bancolombia Consolidated is based on a comparison with the information reported by Grupo Bancolombia as of March 31, 2025.

During the analysis period, adequate liquidity levels were maintained. Bancolombia and Bancolombia Panama stood out for their fundraising capacity, especially in deposit accounts and term deposit certificates (CDTs). This behavior was accompanied by sustained growth in the Bank’s loan portfolio, which helped offset the increase in raised funds and reflected efficient liquidity management. Additionally, liquidity levels complied with established limits and met the requirements of Bancolombia Consolidated, satisfying both internal and regulatory indicators.

During the first half of 2025, the coverage ratio decreased from 247.07% in March 2025 to 209.17% in June 2025. This variation is due to the change in the comparison base, which shifted from Grupo Bancolombia to Bancolombia Consolidated.

BANCOLOMBIA S.A.

During the second quarter of the year, liquidity levels remained within adequate ranges, mainly supported by the positive performance of fundraising through term deposit certificates (CDTs) and deposit accounts. These funds enabled the Bank to meet the growth in loan disbursements without compromising Bancolombia’s liquidity position.

The liquidity indicator stood at 179.79% as of the end of June 2025, showing an increase of 3439 basis points compared to the end of March 2025, explained by the increase in liquid assets.

On the other hand, the Net Stable Funding Ratio (NSFR) has remained above adequate levels, standing at 123.49%, without breaching the established limits. Likewise, year-to-date, an increase of 542 basis points has


19

been observed, considering the creation of Grupo Cibest, which impacted the reduction of Non-Liquid Shares and Technical Equity in June 2025.

CREDIT RISK

Credit risk refers to the probability that Bancolombia Consolidated may incur losses due to the non-fulfillment of financial obligations by a counterparty, issuer, or borrower. This is the principal and largest risk for the banking business, and it must be managed throughout every stage of the credit cycle.

CONSOLIDATED

The analysis presented below for Grupo Cibest Consolidated is based on a comparison with the information reported by Grupo Bancolombia as of March 31, 2025.

As of the end of the second quarter of 2025, Bancolombia Consolidated reported a 23.3% decrease in their loan portfolio compared to March 2025. The total past-due loan ratio at 30 days closed at 4.15% for the second quarter of this year.

The credit cost for Bancolombia Consolidated in the second quarter of 2025 was 1.20%. This result is mainly explained by Bancolombia’s performance, which showed lower deterioration in the consumer loan portfolio and greater release of provisions for specific clients with material exposures.

These variations are mainly explained by the fact that the current analysis of Bancolombia Consolidated is based on a comparison with the information reported by Grupo Bancolombia corresponding to March 2025.

BANCOLOMBIA S.A.

As of the end of the second quarter of 2025, Bancolombia reported a 1.11% growth in its loan portfolio compared to March 2025, mainly driven by increased balances in the individuals and corporate segments. The loan portfolio variation by type was as follows: commercial loans grew by 0.2%, consumer loans by 2.3%, mortgage loans by 4.2%, and microcredit by 18.8%. The 30-day past-due loan ratio closed at 4.41%, representing a decrease of 0.21 percentage points compared to 4.62% in the first quarter of 2025.

Bancolombia’s credit cost for the second quarter of 2025 was 1.6%, lower than the 1.8% recorded in March 2025. This decrease is mainly explained by the release of provisions for individually assessed clients and lower deterioration in the mass portfolio. Additionally, various strategies continue to be implemented for portfolio monitoring and recovery, aiming to normalize and contain the loan portfolio, particularly in the consumer segment.

COUNTRY RISK

This risk refers to the possibility of Bancolombia Consolidated incurring losses as a result of financial operations abroad due to adverse economic and/or political conditions in the country receiving those operations, either because of restrictions on the transfer of foreign exchange or because of factors not attributable to the commercial and financial condition of the country receiving those operations. This definition includes, but is not limited to, sovereign risk (SR) and transfer risk (TR) associated with such factors.


20

The principles and guidelines for country risk management remain consistent with those disclosed as of March 31, 2025.

The analysis presented below for Grupo Cibest Consolidated is based on a comparison with the information reported by Grupo Bancolombia as of March 31, 2025.

At the end of June 30, 2025, no alerts were presented in any investment subject to country risk, nor were adjustments made for deterioration of investments that could affect or deteriorate the financial strength of Bancolombia and its subsidiaries, compared to March 2025. The decrease in the investment portfolio subject to country risk assessment is primarily due to the reallocation of investment companies within the Cibest Group. Additionally, the decrease in the value of investments is due to revaluation factors.

OPERATIONAL RISK

Operational risk is the likelihood that Bancolombia will incur losses as a result of failures or inadequacies in systems, processes, people, infrastructure, or due to external causes or events. Operational risk may also arise from failures in the models or management information used by the organization.

BANCOLOMBIA S.A.

Bancolombia's operational risk system's objective is to carry out an adequate risk management that allows minimizing, avoiding, or reducing the materialization of adverse events and/or reducing their consequences or costs in case of materialization. The operational risk management system has not undergone changes compared to what was disclosed in the previous quarter, in terms of regulations, policies, manuals, methodologies, structure, or any other relevant element that could affect its effectiveness.

During the second quarter of the current year, no new risks or changes in existing risks have been identified that significantly modify the Bancolombia's operational risk exposure. The losses materialized in the second quarter of 2025 reaches out to COP 66,005 million, representing a 29% decrease compared to the first quarter of the current year. This decrease is due to the measurements around external fraud such as adjustments in monitoring models and password blocking, security campaigns and accelerated the migration process to the new APP Mi Bancolombia.

OTHER RELEVANT RISKS

Bancolombia continues to refine its policies and processes with the aim of adequately managing risks in a dynamic and proactive manner, integrating the concerns of business units, corporate areas, and Senior Management. Each identified risk is measured consistently using methodologies deemed appropriate for each case.

To support this, Bancolombia uses a risk map as a tool to identify the most relevant risks to which it is exposed and to define action plans aimed at mitigating them, based on a holistic view that considers both local and international contexts.

Below is Bancolombia's risk map for 2025, which details the relevant changes that occurred in the second quarter of the year, although there were no significant variations in the following risks: environmental and social risk, human talent, third parties and sustainability.


21

Risk Map 2025 – Bancolombia

•Regulatory and Legal Risk

For the second quarter of 2025, significant regulatory movements were registered in Colombia. Firstly, the Congress of the Republic approved the labor reform bill. Although the final version differs from the draft originally submitted by the National Government, it remains one of the administration’s priority initiatives, aimed at reaffirming workers’ rights in areas such as working hours, employment arrangements, and compensation. The direct effects on Bancolombia’s operations will impact certain operational fronts, particularly regarding the dissemination of information and the safeguarding of labor rights for employees. Additionally, the reform may lead to increased operational expenses arising from: (i) services contracted through outsourcing; and (ii) adjustments to the employment arrangements for SENA apprentices. Indirectly, various analysts have indicated that, at the national level, this reform could negatively affect unemployment and informality rates, which in turn may deteriorate credit demand and borrowers’ repayment capacity.

Secondly, the URF1 published a second version of the Draft Decree that would implement the mandatory Open Finance system in Colombia. This version raises several concerns for supervised entities: i) the scheme of responsibility in the process of access and processing of data by unsupervised third parties is not clear, although a model of registration in a directory and the validation of access requirements by the so-called trusted third parties (infrastructure providers) is defined; ii) a free model is proposed, which would prevent charging for access to information or any other concept aimed at recovering the investments made for the implementation and maintenance of the data infrastructure of the providers; and iii) there is no legal certainty about the application of the principle of reciprocity, where some actors could use data from the system without being obliged to provide information to it.

1 URF: Regulatory Projection and Financial Regulation Studies Unit


22

Thirdly, the Financial Superintendence of Colombia released two versions of a draft regulation that seeks to enable financial institutions to manage environmental and social risks, and assess their impact on the financial situation and resilience of the business model. Although the latest version is clear that these risks should not be managed within the Comprehensive Risk Management System (SIAR), the management of social and environmental risks is still in the early stages in the country. This represents a significant challenge for supervised entities, as it is not aligned with international trends, where supervisors have opted for approaches based on recommendations and guidelines, instead of strict regulations, and even in the curbing of this type of measures when referring to financial activity.

•Political risk

In terms of political risk, two risks associated with the country's fiscal situation could be faced: i) a new tax reform focused on eliminating tax benefits and particularly, exemptions from VAT, income tax, taxes on hydrocarbons, inheritances, remittances, as well as making permanent the taxes of the economic emergency of Catatumbo (stamp duty, VAT on online games of luck and chance and imports of hydrocarbons); and (ii) the implications it would have on the Bancolombia's debt ratings and the downgrade of the country's debt ratings.

These risks arise as a result of the complex fiscal situation faced by the government that led it to activate the escape clause of the fiscal rule. This legal mechanism allows the Ministry of Finance to suspend the application of the fiscal rule formula, with which the fiscal deficit could reach up to 7.1% of GDP in 2025 (vs. 5.1% proposed in the Financial Plan presented at the beginning of the year) and public spending would rise by COP $20 billion. In addition, the 2025 Medium-Term Fiscal Framework presented in June, points to the need to process a tax reform for around COP $25 billion.

After the signing of the credit pact between the government and the credit institutions, the President of the Republic has been signaling his disagreement with the amounts disbursed for the so-called popular economy (approximately 35% of the target), which suffers from a delay in disbursements compared to the other sectors (approximately 55% of the target) and insisting on an idea already mentioned above of processing a bill that would create forced investments for the financial sector that allow a greater distribution of resources to these segments of the population. In this regard, the Financial Superintendent has pointed out the existence of difficulties in measuring which credits are classified in this category, implying that it is possible that this amount is underestimated since it is confused with consumer credit in terms of its destination, and it is unlikely that the idea of forced investments will materialize.

During the second quarter of 2025, Colombia’s geopolitical landscape continued to face complexities, particularly in its relationship with the United States, Colombia’s principal trading partner. Certain sectors may be affected by the evolving dynamics between the heads of state of both countries. Colombia's economic conditions could be impacted on account of a reduction in foreign aid from the United States motivated by the budget cuts that the government of that country intends to make and a possible decertification of Colombia in the fight against drugs. Colombia is also one of the countries whose products face 10% tariffs in the U.S., which may affect companies that trade in the international market and the country's external accounts. However, opportunities to compete with countries facing higher tariffs, such as Brazil, may also present themselves on that front.

•Economic and sectoral environment

The beginning of Donald Trump's term in the United States and the tariff measures adopted have positioned themselves as the main determinant of the international macro-financial situation in the first part of 2025. The


23

imposition of universal, sectoral and China tariffs led to the estimated average tariff for imports from the United States rising to the highest in almost a century. These decisions have skewed inflation expectations in the United States, where the view is leaning towards a dynamic of a pronounced increase in prices perceived by households.

This introduces a dilemma for the Federal Reserve's monetary policy decision-making, which has been emphatic in the need for more information and the preference for caution in the midst of this environment of high uncertainty. Meanwhile, the markets have reacted strongly: the risk-averse sentiment deepened, which boosted a flight-to-quality2 in the decisions of international investors. Financial assets in emerging economies have been affected.

For Colombia, this global environment would have mainly financial implications: the exchange rate weakened after a relatively benevolent start to the year, while oil prices were below USD70 per barrel for much of the first half of the year. In addition, global risk aversion led to a widespread increase in the sovereign risk premium among emerging economies, which affected Colombia to a greater extent due to the prevailing vulnerabilities in the fiscal outlook.

The local economy continues to travel along the path of recovery of GDP growth and reduction of inflation that was already observed during 2024. Meanwhile, the imposition of the 10% universal tariff on Colombian products has limited implications for the export sector: a large part of the tariff was offset by the devaluation of the exchange rate, while the situation relative to other countries did not change significantly – it improved with China, on which the United States imposed a much higher tariff. and it only weakened in the face of the goods that are part of the trade agreement between Mexico, Canada and the U.S.

Thus, it is foreseeable that the Colombian economy will continue to advance on the path of progressive macro stabilization (in GDP growth, inflation, and interest rates), which implies a short-term environment that will be more constructive than what was seen in 2024. The 10% tariff on Colombian goods may generate moderate risks in some specific productive activities, while financial turbulence has positioned itself as the main source of macro uncertainty for the short-term future.

In view of this, Bancolombia maintains an active management of credit risk, incorporating various macroeconomic scenarios into the provisioning calculation models. In addition, Bancolombia has maintained a constant sectoral analysis and monitoring, with the aim of identifying both situations and customers with possible impacts. Periodically, the evolution of the individual situation of customers is reviewed in different forums, adopting alternatives when necessary, to support them in the development of their businesses and in the management of the aforementioned context.

•Third-party risk

The outsourcing of activities within Bancolombia exposes it to a possibility of economic impact derived from the inability to manage a third party or contracted supplier, which presents deficiencies to carry out the service. This situation can trigger restrictions in the achievement of strategic objectives, and in some cases, lead to impacts on the operation of businesses and increase exposure in terms of cybersecurity, fraud, handling of third-party or confidential information.

2 Flight-to-quality: dynamics in which international investors move their resources from assets considered risky (e.g., stocks or assets of emerging countries) to destinations considered safer (e.g., debt bonds of the governments of the most developed economies or gold). It usually occurs in environments of high economic uncertainty and volatility in the financial markets


24

During the second quarter of 2025, the continuous process of evaluation of Bancolombia's critical suppliers continues, in this way it seeks to guarantee the control environment and continue with the evolution of the processes to guarantee the management of suppliers in the contracting cycle.

•Business continuity and technology failures

In terms of operational resilience, business continuity and technological failures, progress continues in the modernization of key services, leveraged on the migration to cloud components. Likewise, a robust contingency based on a fourth-generation Core is being implemented, with an emphasis on critical channels and processes. These actions will allow a greater capacity to respond to eventualities, improving resilience and mitigating in a timely manner the impacts on the service to our customers.

•Model Risk

During the second quarter of 2025, key progress was made in consolidating the model risk management framework. The design phase of the Comprehensive Framework for the Validation of Generative AI Models was completed, updating the methodology for tiering analytical tools by incorporating criteria of impact, robustness, explainability and ethical use; additionally, the general guidelines for the risk management of models are updated, an annex was created with special guidelines for Generative AI models and specific guidelines were developed for the use of the Generative AI Model. Mandatory validation and technical tests, applicable from the second semester. The automation of the validation process was significantly expanded by incorporating additional quantitative modules focused on provisioning and liquidity risk models, with a 30% reduction in average review times compared to the usual standard and strengthening the complete traceability of the process. In addition, an early warning engine was successfully implemented to anticipate deadlines of findings and action plans derived from the independent validation of models, generating proactive alerts aimed at reducing the average time to close. These advances allow the risk profile to be maintained at a moderate level with a stable trend in the face of changes in the environment and in the Bank's processes.

•Cybersecurity and information security risk

So far in the second quarter of 2025, there have been no relevant changes that significantly modify the exposure to cybersecurity and information security risk, however, to strengthen the management of this risk, controls have been consolidated and improved based on access management, alerts and monitoring through the different layers of control. highlighting the implementation of the consolidation of different antimalware technologies in a standardized way with advances in their integration, as well as the strengthening of information labeling controls as a prevention measure that allows exposure to risks to be kept under control. In addition, the construction, disclosure and approval of the technological and cyber risk management policy is highlighted, which will provide a more structured governance and action framework on risk.

•Risk response to market changes

The Colombian financial sector demonstrates a mixed landscape, with opportunities and challenges. Moderate growth is expected, driven by the economic recovery and declining inflation, but risks related to global uncertainty and monetary policy are also observed. Traditional players and digital competitors (Fintech and Neobanks) continue to execute user attraction strategies to boost key registrations in the face of the deployment of the Bre-B.


25

As for the Bre-B System, in this initial phase of registration there are more than 20 million keys registered by more than 8.5 million customers throughout the system, that is, on average there are more than 2 keys per customer. In turn, more than 93% of the registered accounts are concentrated in natural persons and the rest are legal entities. It is noteworthy that it is essential for Bancolombia to maintain its leadership at the time of key registration during this first stage.

Finally, during this phase, negative impacts have been evidenced due to external fraud, mainly crimes associated with social engineering, which weakens users' trust in the system.

•Internal Fraud Risk

During the second quarter of 2025, various actions were carried out aimed at strengthening risk management. These include training and awareness-raising activities aimed at all employees, implemented through different strategies that promote an organizational culture based on zero tolerance for fraud. Likewise, accompaniment and diagnosis of the processes was carried out, applying a risk-based approach. New controls were implemented and existing ones were improved, and progress was made in the evolution of tools that support risk management.

•FTA Risk and Corruption

In the management of SARLAFT during the second quarter of 2025, the LAFT risk matrices for Bancolombia, Valores Bancolombia, Fiduciaria Bancolombia and Banca de Inversión Bancolombia, continue to be in force, ensuring optimal results for each entity through constant evolution in risk mitigation.

To facilitate the self-management of knowledge against LAFT risk throughout Bancolombia, a Compliance Risk Chatbot was implemented. This tool will allow employees to access relevant and frequent information on compliance risks in a timely, clear and understandable way.

In order to stay informed about the external context, in collaboration with the Financial Superintendence of Colombia and other entities in the sector, an analysis of the internal and external environment is being carried out. The purpose of this analysis is to understand the new modalities of source crimes, with special emphasis on crimes against the public administration, extortion and smuggling in the area of Bancolombia.

Likewise, as part of the institutional strengthening strategy led by the Vice Presidency of Compliance, the integration of the SARLAFT and Economic Sanctions management has been carried out, with the aim of optimizing resources, strengthening comprehensive risk management and improving operational efficiency. This integration allows for the consolidation of complementary functions, the generation of synergies between the teams, and the adoption of a more holistic view of the risks associated with money laundering, terrorist financing and compliance with international sanctions. The new organizational structure will facilitate a greater capacity to respond to alerts, reduce duplication in processes, and improve the traceability and control of the decisions taken.

To strengthen the culture of prevention among employees and suppliers, Bancolombia continues to promote awareness through various communications, training sessions, and educational programs. These initiatives directly enhance knowledge related to AML/CFT prevention within Bancolombia.

•Risk of External Fraud

During the second quarter of the year, fraud risk management remained a strategic priority for Bancolombia. In the realm of external fraud, social engineering tactics, particularly Tabot spoofing and vishing, continued to pose a significant challenge. To address this challenge, actions have been carried out to strengthen our prevention, containment and response models. These include accelerating the maturation of engines, optimizing monitoring rules focused on behavioral patterns, and intensifying financial education initiatives on how to use products and channels safely and easily, with an emphasis on preventing social engineering-based modalities for customers.

New capabilities have been acquired that allow us to understand customers' behavioral and transactional behavior, as well as their uses and preferences, to make more informed decisions. Among the actions implemented, real-time self-management for the confirmation of suspicious transactions stands out, which provides greater agility and control to the customer. Likewise, the security flow in Tabot was redesigned, allowing the unlocking of dynamic keys directly through the virtual assistant, which significantly improves the user experience. Additionally, streaming models with their own capabilities were implemented, which allow hyper-personalizing customer transactions based on their patterns and behaviors, providing greater precision and efficiency in security and validation processes.
