Strong bank, shaky country
- The core bank earns most of its money from lending at higher rates than it pays on deposits.
- Management lifted 2026 NIM guidance to 7.0% to 7.2% and ROE guidance to 19.5% to 20%.
- Nequi has 27.4 million users, close to an 80% activity ratio, and made about $7 million in Q1 administrative net income.
- The new holding company structure supports a COP 1.3 trillion buyback and the $1.4 billion Banistmo sale.
- The main worry is Colombia itself: weak public finances, sticky inflation, higher rates, and election-linked policy risk.
Good bank, hard backdrop
Grupo Cibest is the new holding company over Bancolombia and its related businesses. The bull case starts with a simple banking edge: a large Colombian deposit base gives it funding that can be cheaper than what smaller rivals pay. That helps net interest margin, or NIM, which is the spread between what a bank earns on loans and securities and what it pays for funding.
That edge is showing up in guidance. After Q1 2026, management raised 2026 NIM guidance to 7.0% to 7.2% and ROE guidance to 19.5% to 20%. The group is also becoming cleaner. It has a COP 1.3 trillion share repurchase program, about 32% executed as of the end of 2025, and agreed to sell Banistmo in Panama for $1.4 billion in cash.
Nequi is the growth option inside the bank. The platform, now combined with Bancolombia A la Mano, reached 27.4 million users with an activity ratio close to 80%. It broke even in Q4 2025, made about $7 million of administrative net income in Q1 2026, and should start separate accounting in Q3 2026.
The bear case is not that the bank is weak. It is that the country around it can pressure even a good bank. Colombia faces a projected fiscal deficit above 7% of GDP, S&P downgraded the sovereign rating to BB-, and management expects 2026 cost of risk near the high end of its 1.6% to 1.8% range.
Spread income plus fees
Grupo Cibest makes money like a universal bank. It takes deposits, makes loans, buys securities, and earns fees from cards, payments, banking services, insurance distribution, trust services, brokerage, and other products.
The key engine is net interest income. In 2025, the 20-F said net interest and valuation income was COP 19,426 billion, up 1.35% from 2024. Lower funding costs helped offset lower loan yields. That is why the deposit base matters so much.
Fees add a second profit stream. Gross fee and commission income from continuing operations was COP 7,929 billion in 2025, up 11.25% from 2024. Cards were about 41% of total fee income, while payments and collections, banking services, and bancassurance were each about 14%.
The model breaks when credit losses rise faster than revenue, deposit costs jump, or regulators force banks to hold low-return assets or pay new taxes. Those risks are live in Colombia, so the stock deserves credit for strong execution but not a free pass on country risk.
What customers use
Colombian banking
This is the core business. It includes deposits, consumer loans, mortgages, corporate banking, cards, and payments in Colombia.
Commercial lending
The bank lends to companies across Colombia and Central America. Demand has been mixed, with Colombia and Panama weaker while El Salvador and Guatemala have shown better activity.
Consumer credit and mortgages
Mortgage loans were a growth area in 2025, especially in Colombia. Consumer lending started growing again after two years of contraction, but management is still focused on lower-risk clients.
Nequi
Nequi is the digital bank inside the group. It has 27.4 million users, close to an 80% activity ratio, and is moving to separate accounting in Q3 2026.
Central American banks
Banco Agricola in El Salvador remains profitable. BAM in Guatemala improved sharply, reaching a 16.2% ROE in Q1 2026 after cost and credit work.
Banistmo
Banistmo in Panama is being sold for $1.4 billion in cash. The sale should simplify the group and free capital, but it must still close as planned.
Colombia still dominates
This mix uses 2025 gross fee and commission income by reported operating segment from the 2025 20-F. Banistmo is shown separately as discontinued because it is being sold, and this is a fee mix, not a total revenue mix.
What could go wrong
Colombia fiscal stress
High impact · High oddsManagement warns that high 2026 spending could create the highest fiscal deficit in Colombia's recent history. S&P downgraded Colombia to BB-, which can raise borrowing costs for the government, companies, and banks.
Credit costs hit the ceiling
High impact · Medium oddsAsset quality improved in 2025, but management expects 2026 cost of risk near the top of its 1.6% to 1.8% guidance range. Higher rates and sticky inflation can make loans harder to repay, especially for households.
Regulatory capital drag
Medium impact · Medium oddsBanks face possible new equity taxes and possible mandatory investments. These rules could take cash away from buybacks, dividends, lending, or digital growth.
Nequi growth costs more than expected
Medium impact · Medium oddsNequi is now profitable on an administrative basis, but it still needs heavy investment. The company expects 2026 capital expenditures of COP 1,066 billion, up 36% from 2025, mainly for digital channels.
Banistmo sale delay
Medium impact · Low oddsThe Banistmo sale is part of the simplification story. If the $1.4 billion cash deal is delayed or blocked, investors may question how fast the new holding company can turn structure into real capital returns.
In one breath
Is Grupo Cibest the same as Bancolombia?
Grupo Cibest is the holding company created above Bancolombia and its related businesses. Bancolombia remains the main operating bank and the heart of the group.
Why does Nequi matter for CIB stock?
Nequi gives the group a large digital customer base and a way to serve lower-income and mobile-first users. It has 27.4 million users and should begin separate accounting in Q3 2026, which may make its value easier to judge.
What is the biggest risk for Grupo Cibest?
The biggest risk is Colombia's macro and policy backdrop. A larger deficit, inflation, higher rates, or new bank rules could raise credit losses and reduce capital returns.
Why is Banistmo being sold?
Banistmo had become a drag on regional profitability, and the sale simplifies the group. The agreed price is $1.4 billion in cash.
