Before you can build a valuation model, you need raw materials. In the world of finance, these materials are found in standardized regulatory filings and financial statements. For beginners, the sheer volume of data can be overwhelming, but knowing where to look and what to ignore is the key to efficient research .

The Treasure Map: SEC Filings

In the United States, the Securities and Exchange Commission (SEC) requires all public companies to file regular reports to ensure transparency and protect investors . These documents are the primary source of truth for any valuation.

Form 10-K: The Annual Deep Dive

The 10-K is a comprehensive annual report that provides a detailed summary of a company's financial performance and business operations . It is far more detailed than the glossy "Annual Report" sent to shareholders, which often serves a marketing purpose .

Key sections of the 10-K to focus on include:

Item 1 (Business): Describes how the company actually makes money, its products, and its industry .
Item 1A (Risk Factors): A list of everything that could go wrong, from lawsuits to supply chain issues .
Item 7 (Management’s Discussion and Analysis - MD&A): Where management explains the "why" behind the numbers, discussing trends and future outlooks .
Item 8 (Financial Statements): The audited income statement, balance sheet, and cash flow statement .

Form 10-Q: The Quarterly Check-In

The 10-Q is a shorter, unaudited version of the 10-K filed after each of the first three quarters of the fiscal year . It allows investors to track performance throughout the year and see if the company is meeting its annual goals .

Form 8-K: The News Flash

The 8-K is filed whenever a major, unscheduled event occurs that shareholders should know about, such as an acquisition, the departure of a CEO, or a bankruptcy filing .

Quantitative Data: The "Top Line" and "Bottom Line"

When you open these filings, you are looking for specific "quantitative" metrics to plug into your valuation model.

Revenue (The Top Line): The total amount of money brought in. Operating revenue is the most important, as it comes from the core business .
Net Income (The Bottom Line): What is left after all expenses, taxes, and interest are paid .
Earnings Per Share (EPS): Net income divided by the number of shares. This tells you how much profit is "owned" by each share .
Free Cash Flow (FCF): Operating cash flow minus capital expenditures. This is the "real" cash available to be paid to investors or reinvested .
Debt-to-Equity (D/E): A measure of how much the company is using borrowed money to fund its operations .

Qualitative Data: The "Technicolor" Details

Numbers don't tell the whole story. Qualitative research provides the context that helps you decide if the numbers are sustainable .

Competitive Advantage (The Moat): Does the company have a brand, patent, or business model that makes it hard for competitors to beat? .
Management Quality: Are the leaders experienced? Do they have a clear strategy? .
Industry Health: Is the entire sector growing, or is it facing regulatory or technological disruption? .

Step-by-Step: How to Gather Data

If you are starting a valuation today, follow this workflow:

Visit the SEC EDGAR Database: Search for the company by name or ticker symbol to find the latest 10-K and 10-Q .
Check the Investor Relations Website: Most companies have a dedicated page with easy-to-read versions of these filings and presentation slides from their latest earnings calls .
Use a Stock Screener: Tools like FINRA’s Market Data Center or major financial news sites can provide quick summaries of key ratios like P/E and EPS so you don't have to calculate them by hand .
Compare to Peers: Gather the same data for 3-5 similar companies to set the stage for a relative valuation .

Summary Table: 10-K vs. 10-Q

Feature	Form 10-K	Form 10-Q
Frequency	Once per year	Three times per year
Audit Status	Audited by independent accountants	Unaudited
Depth	Extremely detailed; includes history	Condensed; focuses on the quarter
Deadline	60-90 days after year-end	40-45 days after quarter-end
Purpose	Comprehensive annual review	Performance tracking and updates

By gathering this data, you move from the "mindset" of valuation into the "mechanics." You now have the building blocks to decide whether to build a complex DCF model or a quick relative valuation using multiples. The data will tell you which path is most appropriate for the company you are analyzing.
