What Are the Three Core Financial Statements? Income Statement, Balance Sheet, and Cash Flow Statement

fiisual

2025/12/3

According to regulations, publicly listed companies are required to regularly disclose financial reports. This obligation is not only a matter of information transparency — it also serves as a “health checkup report” that companies present to the market. This article provides a brief overview of the three core financial statements — the Income Statement, Balance Sheet, and Cash Flow Statement — outlining their roles and functions. It also highlights how investors can utilize the distinct characteristics of each report to better understand a company’s fundamentals, laying the groundwork for preliminary fundamental analysis.

We’ve previously introduced the basics of financial reports and common indicators. This article will guide you from the ground up to understand the importance of financial statements, how they reflect a company’s operational status, and how you can analyze them to make better investment decisions.

Why Should You Understand Financial Statements?

Have you noticed that many investors in the stock market tend to “buy based on tips” — whether from friends and family, media hype, or influencers? But here's the real question: Where does this information actually come from? Is it backed by solid data? Does it truly reflect the company’s real operating condition?

At its core, investing is about putting your money into a company’s future. And to evaluate whether a company has long-term growth potential, the first step is to understand what its current situation looks like — and financial statements are the most reliable and essential tool for doing so.

By regulation, publicly listed companies must regularly publish financial reports. These reports aren’t just for disclosure obligations — they serve as a health checkup for the company presented to the market. No matter how confident an executive sounds in interviews or how optimistic a shareholder meeting is, the truth lies in the numbers. If a company is facing declining revenue, tight cash flow, or excessive debt, then no matter how good the "vision" sounds, it will eventually be tested by the financials.

Financial reports are a company’s most honest confession to the market — and the starting point for sound investment decisions.

The Three Core Financial Statements = A Company’s Health Checkup

The Three Financial Reports That Reflect Corporate Health

A company's financial report consists of three main parts: the Income Statement, Balance Sheet, and Cash Flow Statement — collectively known as the “three financial statements.”

Just like a medical checkup requires checking your blood pressure, heart rate, and blood tests — because a single metric can’t reveal your full health — you need a combined view to catch hidden risks or issues. The same applies to businesses. These three reports reveal critical aspects such as profitability, financial structure, and cash flow performance.

Only by analyzing all three can you determine whether a company is financially sound, operating smoothly, or showing early signs of financial trouble. Here’s a simple introduction to each of them:

1. Income Statement: Measures if a Company is Making Money

The income statement shows the company’s revenue, costs, operating expenses, and net profit for a given period. It reflects business performance and profitability. By observing indicators such as gross margin, operating margin, and net margin, investors can assess whether the company has a sustainable profit model and whether its efficiency is improving over time.

2. Balance Sheet: Reveals Financial Structure

The balance sheet shows the company’s assets, liabilities, and shareholders’ equity as of the end of the reporting period — essentially, how the company funds and allocates its resources. Analyzing metrics such as debt ratio, current ratio, and total asset turnover helps determine whether a company has a strong financial foundation, reasonable leverage, and the resilience to withstand economic shocks.

3. Cash Flow Statement: Shows Whether Real Money is Coming In

The cash flow statement tracks actual cash inflows and outflows from operations, investing, and financing activities, offering a realistic view of the company’s liquidity. Even if the income statement shows a profit, negative cash flow may indicate problems like poor receivables collection, inventory buildup, or overreliance on financing — all signs of potential financial risk.

What Can Reading Financial Statements Help You Avoid?

One of the most common problems faced by new investors is making poor decisions due to information asymmetry.

Companies may appear attractive on the surface or be the subject of hot market themes. But without reviewing the financials, it’s easy to invest in something only to later find out that the performance doesn’t live up to expectations — or that the business is burning through cash. That’s where financial reports act as a radar, helping you detect warning signs early on.

Here are three common pitfalls financial reports can help you avoid:

1. Loss-Making “Trap Stocks”

By reviewing the income and cash flow statements, you can quickly screen out companies that have long-term losses or lack business momentum. Even if market sentiment is optimistic, a company that can't consistently generate profit likely doesn’t offer real long-term value.

2. “Fake Growth Stocks” with Growing Revenue but Troubled Cash Flow

Some companies may show rapid revenue growth, but if operating cash flow is consistently negative or receivables are abnormally high, it could signal premature revenue recognition or uncollected sales — creating serious accounting and cash flow risks.

3. Highly Leveraged “Time Bomb Stocks”

The balance sheet reveals not just the size of a company’s assets, but also its funding structure and risk exposure. Companies that rely heavily on debt to fund growth may be vulnerable — especially in an environment of rising interest rates and tighter liquidity. These companies can quickly face repayment pressure or even liquidity crises.

Investors can mitigate these risks by regularly reviewing indicators such as the Debt Ratio, Net Debt/EBITDA, and Interest Coverage Ratio, which offer insights into a company’s financial resilience and credit risk.

You Don’t Need to Prepare the Reports — Just Know How to Read Them

Many beginners are intimidated by financial reports because they assume accounting knowledge is required. But the truth is, investors don’t need to know how to prepare the reports — only how to interpret them.

Accountants record, prepare, and audit reports according to accounting standards. An investor’s job is to extract useful insights from those reports and make rational decisions that balance risk and reward.

In short, reading financial statements is a risk management skill in investing. You don’t need complex accounting jargon — just the ability to understand the meaning behind the numbers and sensitivity to what those numbers reveal.

Here are a few key questions — the answers are hidden in the financials. Think them through:

  • If gross margin keeps falling, does that signal worsening cost structure?
  • If operating cash flow is consistently negative, is the business model unsustainable?
  • If net debt rises quickly, could that indicate a cash crunch ahead?

Next Step: Using Financials to Identify Great Companies

Once you understand the structure and logic of the three financial statements, you’ll hold the first key to filtering out high-quality companies. While market prices fluctuate in the short term due to emotions, long-term stock trends always return to fundamentals — and at the core of those fundamentals is the financial report.

How can you spot a good company from its financials? These indicators are proven tools for evaluating financial health and long-term value:

  • Strong and stable profitability: High and consistent gross margin and operating margin over the years.
  • Healthy cash flow: Positive cash flow from operations over time, indicating the business can sustain itself without external funding.
  • Solid balance sheet: Reasonable leverage, current ratio above standard benchmarks, showing risk resilience.
  • High returns on capital: Strong ROE or ROIC, showing the company can generate value for shareholders effectively.

By cross-analyzing these metrics, you can develop your own framework for interpreting financial statements and evaluating companies — so you’re no longer swayed by market noise but guided by financial logic.

Summary

There’s no guaranteed formula for profit in investing, and no such thing as a perfect stock tip. Markets can chase hype or rumors, but what truly protects your capital and builds long-term returns is a deep understanding of how companies actually operate — and calm, rational judgment.

Financial statements aren’t just cold numbers — they record how a business survives, grows, expands, and transforms. Once you learn to read them and develop fundamental financial literacy, you’ll be able to cut through the noise, focus on what matters, spot trends, and stop dancing to the tune of outside opinions.
