Lesson 1: Analyzing a Stock Using Financial Statements

Introduction: From Numbers to Insights

Every stock you see on a chart is not just a ticker symbol. 

It is a business with sales, costs, and strategy. 


And the clearest window into that business is its financial statements. 


In this lesson, you’ll learn how to: 

  • Read and interpret a company’s income statement, balance sheet, and cash flow statement
  • Identify key financial metrics that investors find important 
  • Pull meaningful insights from the numbers using a real-world company example.

Meet the Company: Apple Inc.

Apple is one of the world’s most recognized and valuable companies, known for products like the iPhone, Mac, and Apple Watch.


But behind the sleek devices is a massive global business - and its financials give us insight into how well it’s really performing.


Quick Snapshot: 

  • Founded: 1976
  • Headquarters: Cupertino, California
  • Industry: Consumer Electronics
  • Business Model: Sells hardware, software, and digital services (like iCloud and Apple Music)


Why It’s a Great Case Study:

  • Large, consistent revenue
  • Well-documented financial history
  • Easily accessible public data
  • Offers clear examples across income, balance sheet, and cash flow statements

Income Statement Analysis

The income statement shows how much revenue a company brings in, and what’s left after costs and expenses.


Let’s look at Apple’s income statement highlights (FY 2024 data rounded for simplicity):


Revenue (Sales)

  • Total Revenue: $391 billion
  • Main sources: iPhone, Mac, iPad, wearables, and fast-growing services like iCloud and Apple Music


What to Ask: 

  • Is revenue growing year over year?
  • Which product segments are driving that growth?


Gross Profit and Margin

  • Gross Profit: $180.7 billion
  • Gross Margin: ~46%


Why This Is Important: 

Strong margins suggest pricing power, brand strength, and cost efficiency


Net Income

  • Net Income: $93.7 billion
  • One of the highest in the world across all industries


Key metric:

EPS (Earnings per Share): Tells you how much profit each share earned; useful for comparing performance over time or between companies

Apple’s EPS for 2024: $6.11


Apple’s income statement tells the story of a business with massive scale, consistent profitability, and solid efficiency.

Balance Sheet Highlights

Apple’s balance sheet offers a detailed look at its financial strength, and how it manages its massive business.


Here are the company’s balance sheet highlights for 2024, and what the numbers mean: 


Total Assets

  • $365 billion
  • Includes cash, investments, inventory, and property
  • Reflects Apple’s scale and global reach


Total Liabilities

  • $308 billion
  • Includes long-term debt and other obligations
  • Apple is financially solid, but it does carry significant debt - partly to fund stock buybacks


Shareholder Equity

  • Equity = Assets - Liabilities
  • ~$57 billion
  • While smaller due to buybacks, this isn’t necessarily bad; Apple returns value to shareholders through dividends and repurchases


Key Ratios


Current Ratio: 0.87

(Below 1, but not alarming for a company with strong cash flows)

Debt-to-Equity Ratio: 2.09

(High, indicating Apple uses debt aggressively, but it’s manageable given its profitability)


Apple’s balance sheet shows a company that balances high cash flow with shareholder returns, while still maintaining operational strength.

Cash Flow Statement Insights

  • Apple’s cash flow statement shows that its business doesn’t just earn paper profits, but also generates massive and reliable cash, 


    Here are the key numbers for 2024: 


    Operating Cash Flow

    • $118.3 billion
    • Cash generated from Apple’s regular business activities (e.g., iPhone, services, Mac sales)
    • Shows how strong and consistent the core business is


    Free Cash Flow

    • $108.8 billion
    • Free Cash Flow per Share: $7.09
    • This is the cash Apple has left after capital expenditures - money it can use for dividends, buybacks, or future investments


    Why This Is Important: 

    • Free cash flow is one of the most important indicators of financial health
    • It tells you how much money the business can return to shareholders without borrowing


    Apple’s cash flow confirms what its income statement suggests:

    This is a cash-rich, incredibly efficient company.
