Before buying shares in GTCO, Zenith Bank or UBA, investors should look beyond the share price and examine profitability, dividends, asset quality, capital strength, loan growth and other key financial indicators.
Investing in Nigerian bank stocks can be an attractive way to participate in the country's financial sector, but buying shares simply because a bank is popular or its share price appears cheap can expose investors to unnecessary risks.
Stocks such as Guaranty Trust Holding Company (GTCO), Zenith Bank and United Bank for Africa (UBA) are among the major names followed by investors on the Nigerian Exchange (NGX). Read original
However, the important question for a prospective investor is not simply, “Which bank has the biggest name?”
The better question is: What do the financial numbers say about the bank's ability to generate profits, manage risks and reward shareholders?
Before placing a buy order, investors should consider several important factors.
1. Look at the bank's profit growth
One of the first things investors should examine is whether the bank is consistently making money and whether its earnings are growing.
A single year of strong profit does not necessarily mean that a bank is a good long-term investment.
Investors should compare the bank's profit before tax and profit after tax over several reporting periods.
For example, GTCO reported profit before tax of ₦1.23 trillion for the 2025 financial year, while profit after tax stood at ₦865.75 billion. The company said its core interest and fee income also recorded significant growth during the year.
The important lesson is that investors should look beyond the headline profit figure and ask:
Is profit growing?
What is driving the growth?
Is the growth coming from normal banking operations?
Are exceptional gains responsible for a large part of the profit?
Can the level of earnings be sustained?
A bank whose earnings are consistently supported by its core business may be more attractive than one whose results depend heavily on temporary gains.
2. Check the dividend history
Dividends are another major consideration for investors buying Nigerian bank stocks.
Some investors buy bank shares primarily for capital appreciation, while others are interested in regular dividend income.
Before buying GTCO, Zenith Bank or UBA shares, investors should therefore examine the bank's history of dividend payments.
But investors should not look at the dividend alone.
A high dividend may appear attractive, but it is important to determine whether the bank can continue paying similar dividends in the future.
GTCO, for example, reported another record dividend for its 2025 financial year as part of its shareholder-return strategy.
Investors should therefore ask:
How much dividend does the bank pay?
Has the dividend been consistent?
Is the dividend supported by actual earnings?
What percentage of earnings is being distributed to shareholders?
These questions can provide a clearer picture than simply looking at the latest dividend announcement.
3. Examine the bank's loan growth
Lending is one of the core activities of commercial banks.
When a bank gives loans and customers repay them with interest, the bank can generate income.
However, rapid loan growth is not automatically positive.
Investors should examine whether the bank is expanding its loan book while maintaining good asset quality.
GTCO's 2025 results, for instance, showed net loans increasing from ₦2.79 trillion in December 2024 to ₦3.13 trillion in December 2025, representing 12.4% growth. Deposits also increased by 23.8% during the period.
This illustrates why investors should consider both loan growth and deposit growth.
A bank that attracts more deposits can have a stronger funding base for lending and other activities.
However, investors should also ask whether the loans are being properly managed.
4. Pay attention to bad loans and asset quality
This is one of the most important areas investors should not ignore.
A bank can report impressive revenue and profit growth while simultaneously experiencing problems with customers failing to repay loans.
Investors should therefore examine indicators such as:
Non-performing loans (NPLs)
Stage 3 loans
Cost of risk
Loan-loss provisions
Impairment charges
These figures help investors understand the level of credit risk within a bank.
GTCO said its Group IFRS 9 Stage 3 loans closed at 5.0% in 2025, compared with 5.2% in December 2024, while its cost of risk improved to 2.2% from 4.9%.
The important point for investors is not to look at one number in isolation.
A rising loan book combined with worsening bad loans could be a warning sign, while healthy loan growth accompanied by controlled credit losses could indicate stronger risk management.
5. Check the bank's capital strength
Capital is extremely important in banking.
Banks need sufficient capital to absorb unexpected losses and support future growth.
This is why investors should pay attention to the Capital Adequacy Ratio (CAR) when studying a bank.
A strong capital position can give a bank more room to expand its operations and withstand financial shocks.
GTCO reported a Capital Adequacy Ratio of 43.8% at the end of 2025, according to its audited results.
Investors should similarly examine the capital position of Zenith Bank and UBA using their latest financial statements.
The objective is not simply to identify the bank with the highest number, but to understand whether the bank has adequate capital relative to its regulatory requirements, risk profile and growth ambitions.
6. Don't ignore return on equity
Another useful measure is Return on Equity (ROE).
ROE gives investors an indication of how effectively a company is using shareholders' funds to generate profit.
For a bank investor, this can be particularly useful when comparing major financial institutions.
GTCO reported a post-tax return on average equity of 28.3% for 2025, according to its full-year results.
When comparing GTCO, Zenith and UBA, investors can examine their respective ROE figures and then investigate why one bank is producing a higher or lower return.
However, a very high ROE should not automatically be interpreted as a reason to buy.
Investors should determine what is driving the return and whether it is sustainable.
7. Look at the share price — but don't stop there
The price of a stock is important, but the price alone does not tell an investor whether a share is cheap or expensive.
For example, one bank's shares may trade at ₦100 while another trades at ₦50.
That does not mean the ₦50 stock is automatically cheaper.
Investors should consider valuation measures such as:
Price-to-earnings ratio (P/E)
Price-to-book ratio (P/B)
Earnings per share (EPS)
Dividend yield
Book value per share
These measures provide more useful information when comparing different banks.
The question should therefore be:
“What am I paying for each naira of earnings or shareholders' equity?”
rather than simply:
“How much does one share cost?”
8. Study the bank's strategy and business model
Two banks can produce similar profits while having very different strategies.
GTCO, for example, operates as a financial services group with banking as well as businesses covering areas such as payments, pensions and funds management.
UBA also operates across multiple African markets and provides investors with financial reports, share-price information and analyst presentations through its investor-relations platform.
Zenith Bank likewise operates a banking group with international subsidiaries, including operations outside Nigeria. Its 2025 annual report provides detailed information about the group's financial position and subsidiaries.
Investors should therefore understand what each bank is trying to achieve.
Questions to consider include:
Is the bank expanding locally or internationally?
Is it investing heavily in technology?
Is it growing its retail banking business?
Is it targeting corporate customers?
Is it diversifying into other financial services?
How much capital will future expansion require?
Understanding the strategy can help investors determine whether the company's future plans fit their investment objectives.
GTCO vs Zenith vs UBA: What Should Investors Compare?
Rather than asking which of the three banks is automatically the best, investors can create a simple comparison table using the latest financial reports.
| What to check | GTCO | Zenith Bank | UBA |
|---|---|---|---|
| Profit growth | Check latest results | Check latest results | Check latest results |
| Dividend history | Important | Important | Important |
| Earnings per share | Compare | Compare | Compare |
| ROE | Compare | Compare | Compare |
| Loan growth | Examine | Examine | Examine |
| Non-performing loans | Examine | Examine | Examine |
| Capital adequacy | Examine | Examine | Examine |
| Cost-to-income ratio | Compare | Compare | Compare |
| P/E ratio | Compare current valuation | Compare | Compare |
| Price-to-book | Compare | Compare | Compare |
| Business diversification | High | Broad banking operations | Broad African presence |
| Long-term strategy | Study | Study | Study |
This approach is more useful than choosing a stock simply because it is trending on social media.
Don't Buy Because the Share Price Has Fallen
One common mistake among new investors is assuming that a stock is automatically a bargain because its price has fallen.
A falling share price could create an opportunity, but it could also reflect concerns about the company's earnings, valuation, economic conditions or future prospects.
Before buying, investors should ask why the price has fallen.
Similarly, a rising share price does not automatically mean that a stock is too expensive.
The underlying financial performance and valuation still matter.
Watch Interest Rates and the Nigerian Economy
Bank stocks are closely connected to the wider economy.
Changes in interest rates, inflation, foreign-exchange conditions, government policies, monetary policy and economic growth can affect banks' earnings.
For Nigerian banks, investors should pay attention to how changing economic conditions affect:
Lending rates
Deposit costs
Loan demand
Government securities
Foreign-exchange positions
Credit losses
Customer deposits
Investment income
This is why investors should not analyse GTCO, Zenith or UBA in isolation from the Nigerian economy.
Read the Actual Financial Statements
Investors do not have to depend entirely on social media posts or stock-market commentators.
The banks publish financial reports that contain detailed information about their operations.
GTCO maintains an investor-relations section containing its annual reports, financial statements and investor presentations.
UBA also provides financial reports, analyst presentations and share-price information through its investor-relations platform.
Zenith Bank's annual and interim reports provide information investors can use to assess its financial performance and position.
Reading these reports can help investors understand what is actually happening inside a company instead of relying solely on headlines.
What Should a New Investor Do Before Buying?
A beginner considering any of these bank stocks can follow a simple process.
Step 1: Find the latest financial results.
Step 2: Check profit growth.
Step 3: Examine EPS and ROE.
Step 4: Check dividend history and current yield.
Step 5: Examine loan growth and bad-loan figures.
Step 6: Check capital adequacy.
Step 7: Compare the stock's valuation with its peers.
Step 8: Study the bank's strategy and major risks.
Step 9: Consider whether the investment matches your financial goals and risk tolerance.
Step 10: Only then decide whether the stock deserves further consideration.
Final Takeaway
GTCO, Zenith Bank and UBA are major names in Nigeria's banking sector, but their size and popularity should not be the only reasons an investor considers buying their shares.
The smarter approach is to examine earnings, dividends, loan growth, asset quality, capital strength, valuation, return on equity and long-term strategy.
Investors should also remember that past performance does not guarantee future returns. Share prices can rise or fall, dividends can change and banking-sector conditions can shift.
For anyone considering investing in Nigerian bank stocks, the goal should not simply be to find the cheapest share.
The goal should be to understand what you are buying, what you are paying for it and what could make the investment succeed or fail.
