Two companies can report billions of naira in revenue, yet only one may deserve your money. One might be growing its sales while quietly accumulating debt. Another might announce impressive profits that are largely driven by foreign exchange gains rather than its core business. On the surface, both look successful. But when you examine their financial statements, the difference between a promising investment and an expensive mistake can become clear.
This is why experienced investors do not buy stocks simply because a company is popular, its share price is rising, or someone on social media recommends it. They examine the numbers behind the business. Revenue growth, profit margins, debt, cash flow, and dividend sustainability can reveal whether a company is financially healthy or hiding problems that could hurt shareholders. If you are new to the market, start with our Nigerian stock investing guide to understand the broader investment process.
In this guide, you will learn how to read company financial statements before buying a stock in Nigeria, even if you have no accounting background. We will break down the income statement, balance sheet, and cash flow statement, explain the financial ratios that matter, and show you the warning signs to look for before investing in companies listed on the Nigerian Exchange (NGX).
The Income Statement (tracks profitability and growth)
The income statement shows how much money a company earns and spends over a specific period, usually a quarter or a year. Before buying a stock on the Nigerian Exchange (NGX), examine this statement to understand whether the business is growing and making a profit.
Start with revenue, also called sales or turnover. It shows how much money the company earns from selling its goods or services. Next, check gross profit and operating profit to see how well the company controls production costs and running expenses. Profit Before Tax (PBT) shows earnings before tax, while Profit After Tax (PAT) is what remains after expenses and taxes. Earnings Per Share (EPS) shows how much profit is attributable to each ordinary share.
Compare the company’s results with the same period in the previous year rather than looking only at consecutive quarters. This helps you account for seasonal changes that may affect sales and profits. Also, check whether foreign exchange gains, asset sales, or unusual other income have increased reported profits.
Finally, review several years of results where available. Consistent growth in revenue, profit, and EPS can indicate a stronger business, but always investigate the reasons behind the numbers before investing.
The Balance Sheet (assesses financial strength and risk)
The balance sheet shows a company’s financial position on a particular date. It lists what the company owns, what it owes, and the value left for its shareholders. The basic accounting equation is Assets = Liabilities + Shareholders’ Equity.
Assets include cash, money customers owe the company, inventory, buildings, and equipment. Liabilities are the company’s debts and obligations, such as supplier payments, short-term loans, and long-term borrowings. Shareholders’ equity represents the value remaining for shareholders after liabilities are deducted from assets.
To assess financial risk, examine the debt-to-equity ratio, which compares a company’s debt with its equity. A rising ratio may indicate greater financial risk, although acceptable levels differ across industries. Also check the current ratio, calculated by dividing current assets by current liabilities, to see whether the company can cover its short-term obligations.
In Nigeria, pay close attention to foreign-currency debt because a weaker naira can increase the cost of repaying loans in dollars or other currencies. Finally, check whether shareholders’ equity is growing and whether the company has enough resources to meet its financial obligations.
The Cash Flow Statement (confirms real cash generation)
The cash flow statement shows how money moves into and out of a company during a specific period. It helps you check whether the business is generating enough cash to support its reported profits.
The statement has three sections. Operating activities show cash generated from the company’s main business, while investing activities record cash spent on or received from assets and investments. Financing activities cover cash from loans, debt repayments, share issues, and dividend payments.
Pay attention to operating cash flow. Consistently positive figures suggest that the company can generate cash from its normal activities. Free cash flow is operating cash flow minus capital expenditure, such as money spent on equipment and facilities. It shows how much cash may be available for debt repayment, dividends, or reinvestment.
Negative investing cash flow is not necessarily a bad sign because it may mean the company is expanding. However, investigate when reported profits keep rising while operating cash flow remains weak. Check whether unpaid customer bills, growing inventory, or other factors explain the difference.
Essential financial ratios
Financial ratios help you understand a company’s performance and decide whether its stock is worth considering. Profit margins show how much revenue remains as profit, while Return on Equity (ROE) measures how effectively a company uses shareholders’ funds to generate profit. The Price-to-Earnings (P/E) ratio compares the share price with earnings per share, while the dividend payout ratio shows the share of earnings paid to shareholders as dividends.
Compare these ratios with those of similar companies and the company’s past results. No single ratio guarantees a good investment because suitable benchmarks vary across industries. If you are interested in companies that distribute profits to shareholders, our guide to dividend stocks on the NGX explores Nigerian-listed companies from an income-investing perspective.
Watch for red flags such as rising revenue but falling profit margins, profits boosted by one-off gains, weak operating cash flow, rapidly increasing debt, and repeated share issues that reduce existing shareholders’ ownership. Also, check for auditor concerns or unclear explanations in the notes to the financial statements.
Before buying a stock on the Nigerian Exchange (NGX), use this checklist:
- Understand the company’s business model and major risks.
- Compare at least three years of financial results, where available.
- Compare its performance with similar companies in the same sector.
- Review the auditor’s opinion, accounting notes, and related-party transactions.
- Assess whether the share price is reasonable and dividends are sustainable.
- Write down why you want to invest and what could make your decision wrong.

Popular questions on stock fundamental analysis
1. Where can I find financial statements of NGX-listed companies?
You can download the official reports free of charge from the Nigerian Exchange (NGX) website at ngxgroup.com under the company filings or issuer information section. Most companies also publish them on their investor-relations pages. In addition, several platforms such as NGN Market and other stock analysis sites collect and present the same data in easier-to-read formats, including historical tables and pre-calculated ratios.
For practical examples of researching individual companies, see our guides on MTN Nigeria shares and Dangote Cement shares. Use company reports and official market disclosures to verify their financial performance before making an investment decision.
2. What are the three most important financial statements I should read?
The three core statements are the Income Statement (also called Statement of Profit or Loss), the Balance Sheet (Statement of Financial Position), and the Cash Flow Statement. The Income Statement shows how much profit the company made over a period, the Balance Sheet reveals what it owns and owes at a specific date, and the Cash Flow Statement tracks the actual movement of cash. Reading all three together prevents you from being misled by any single number.
3. Should I compare quarterly results with the previous quarter or the same quarter last year?
Always prioritise year-over-year (YoY) comparisons. Many Nigerian businesses experience strong seasonal patterns, for example, higher sales during festive periods or harvest seasons. Comparing Q2 of the current year with Q2 of the previous year gives a clearer picture of genuine growth or decline, whereas sequential quarter comparisons can create false impressions of improvement or deterioration.
4. Why do Nigerian companies sometimes report big profits that later reverse?
Reported profits can be boosted by non-recurring items such as gains from the sale of assets, fair-value adjustments, or large net foreign-exchange gains caused by naira movements. These one-off or volatile items do not reflect the strength of the core business. Always read the notes to the accounts carefully to separate sustainable operating profit from temporary gains that may not repeat in future periods.
5. What Debt-to-Equity ratio is considered safe in Nigeria?
A Debt-to-Equity ratio below 1.5 is generally viewed as comfortable for many NGX-listed companies, while ratios above 2.0 usually indicate higher financial risk. Extra caution is required when a significant portion of the debt is denominated in foreign currency, because naira depreciation can sharply increase the naira value of that debt and the related interest burden.
6. Is a positive Profit After Tax enough, or must I also check cash flow?
A positive Profit After Tax is necessary but not sufficient. Accounting profit includes non-cash items and estimates. The Cash Flow Statement, particularly cash generated from operating activities, shows whether the company is actually collecting cash from its customers. Prefer companies whose operating cash flow is consistently positive and broadly aligns with reported profits over several periods.
7. What is a good Return on Equity (ROE) for NGX stocks?
An ROE above 15 percent is often considered attractive because it shows management is generating strong returns on shareholders’ capital. However, acceptable levels vary by sector. Banks, consumer-goods companies, and industrial firms have different typical ranges, so always compare a company’s ROE with its direct peers rather than applying a single absolute benchmark.
8. How important is the Price-to-Earnings (P/E) ratio?
The P/E ratio tells you how many naira the market is willing to pay for each naira of the company’s earnings. It is a useful valuation tool only when placed in context: compare it with similar companies in the same sector, the company’s own historical average, and its expected earnings growth. A low P/E may signal undervaluation or simply reflect higher perceived risk or weaker prospects.
9. What are the biggest red flags for Nigerian stocks?
Watch for declining profit margins even when revenue is rising, profits that rely heavily on one-off gains or foreign-exchange movements, rapidly increasing debt levels, frequent issuance of new shares that dilute existing shareholders, and operating cash flow that remains weak or negative for several consecutive periods. Any of these patterns should prompt deeper investigation before you invest.
10. Do I need to be an accountant to analyse these statements?
No. You only need to focus on a manageable set of key figures and ratios: revenue growth, Profit After Tax and EPS trends, operating cash flow, debt levels, margins, ROE, and valuation relative to peers. With regular practice and a simple checklist, most retail investors can extract the information needed to make more informed decisions without formal accounting training.
