Research Dossier for a Target Company: How to Build One

Building a research dossier for a target company is mostly a question of knowing which documents the company is already required to publish about itself. For public companies, the most useful material is free, official, and written by the company’s own management. Most people never open it.

Below you will find what belongs in a dossier, the filings that carry the most signal and how to read them, what to do when the company is private and files nothing, and the line between research and conduct that can be illegal.

Research Dossier for Target Company: What Goes In It

Six sections, kept to a page or two. A dossier that runs to twenty pages does not get read, including by the person who wrote it.

• Basics. Legal entity name, headquarters, size, ownership, and corporate setup. The legal name often differs from the brand.
• How they make money. Products, main customer types, and which segment brings in most of the revenue.
• Direction of travel. Recent results, funding, acquisitions, expansions and closures.
• Pressures. The risks and problems the company itself acknowledges.
• People. Decision makers relevant to your purpose, their remit, and how long they have been in post.
• Your angle. One paragraph on why any of the above matters for the meeting, application or decision ahead.

The last section is the one that turns research into something useful. From what we’ve seen, dossiers fail in one of two ways: they are a wall of facts with no argument, or they are an argument with no evidence behind it.

Which Public Filings Carry the Most Signal?

The annual report on Form 10-K, and it is free. The U.S. Securities and Exchange Commission’s EDGAR full-text search covers filings back to 2001, so you can search inside documents rather than guessing which one to open.

The SEC’s own guide to reading a 10-K explains what each part holds, and four sections do most of the work:

• Item 1, Business. How the company operates. The SEC calls this “a good place to start to understand how the company operates.”
• Item 1A, Risk Factors. The most significant risks facing the company. The SEC notes that “companies generally list the risk factors in order of their importance,” and that the section “focuses on the risks themselves, not how the company addresses those risks.”
• Item 3, Legal Proceedings. Significant pending lawsuits, “other than ordinary litigation.”
• Item 7, MD&A. Management’s discussion and analysis, which the SEC describes as giving “the company’s perspective on the business results of the past financial year” and allowing “company management to tell its story in its own words.”

One thing most guides miss is that ordering detail in Item 1A. If risk factors are generally listed by importance, then the first two or three items are the company telling you, in writing, what worries it most. That is a better guide to a company’s priorities than any press release, and it is the fastest way to find a problem you can speak to.

Two other filings repay the time. The DEF 14A proxy statement covers executive pay, board composition and shareholder matters, which shows what leadership is genuinely rewarded for. Form 8-K covers material events between annual reports, including leadership changes and acquisitions.

What If the Company Is Private?

You lose the filings and have to assemble the picture from traces the company leaves elsewhere. It is slower, and often more revealing.

1. Job postings. The most underrated source on a private company. What they are hiring for, in which locations, and at what seniority tells you where money is going right now.
2. State business registries. Incorporation records, registered agents, officers and status. Free in most U.S. states.
3. Trademark and patent filings. Public records that hint at product direction before launch.
4. Customer evidence. Case studies, logos on the website, conference sponsorships and review sites.
5. Local and trade press. Regional business journals cover private companies national outlets ignore.
6. Court records. Litigation is public, and disputes reveal suppliers, contracts and disagreements.

The myth worth clearing up: people assume a private company means no public information. A private company still hires, registers, files trademarks, sues and gets sued. What disappears is the audited financial picture, not the company’s footprint. Be careful about inferring revenue from headcount or office size, since both are weak proxies that lead to confident, wrong numbers in a dossier.

Where Is the Legal Line?

At misrepresenting who you are in order to obtain information. Reading public filings, job ads and court records is research. Pretending to be someone else to extract information is a different activity, and in some cases a crime.

The clearest example is financial information. Under the Gramm-Leach-Bliley Act, it is unlawful to obtain or attempt to obtain a customer’s information from a financial institution by making false, fictitious or fraudulent statements. The practice is known as pretexting, and the Federal Trade Commission has brought enforcement actions over it. The FTC’s overview of the Gramm-Leach-Bliley Act sets out what the law covers.

If the research supports a contract or a deal, our roundup of AI legal tools for small business owners covers the review side.

The same principle applies more widely even where a specific statute does not. Calling a company’s staff while posing as a customer, a student or a supplier to extract commercial information is deception, and it can expose you and your employer to legal and reputational consequences.

A common mistake worth avoiding: treating a target’s employees as a research source through casual conversation that hides your purpose. If you are researching a company for a sales approach, an investment or a competitive review, say so when you speak to people connected with it. The information you gain by concealing it is rarely worth what it costs if it comes out, and it almost always comes out eventually.

Where your dossier includes named individuals, keep it to professional information relevant to your purpose, and be aware that compiling personal data on people in the EU or UK carries obligations under data protection law. If you are unsure, ask a lawyer rather than guessing.

Building a Research Dossier for Target Company Meetings

Work outside in, and set a time limit before you start. Company research expands to fill whatever time you give it.

1. Confirm the legal entity first. Get the exact registered name and check whether it is a subsidiary. This prevents researching the wrong company.
2. If public, read Item 1A and Item 7 first. The top risk factors and management’s own narrative give you more in twenty minutes than anything else.
3. If private, start with job postings and the registry. Hiring shows direction; registration shows ownership details.
4. Check the last twelve months of news, then stop. Older coverage rarely changes a current decision.
5. Note who is new in post. Executives appointed in the last year are usually still forming their agenda.
6. Write the “so what” paragraph last. If you cannot write it, you have collected facts rather than insight.
7. Date the dossier and set a refresh point. Anything older than a quarter needs a check before you rely on it.

After looking at how these get used, we prefer a one-page dossier with a linked appendix over a long document. The page is what gets read before a meeting; the appendix is where the filing extracts and links live for anyone who wants to verify a claim. Tools can speed up the collection step, and our roundup of the best AI agents for productivity covers options, though everything they produce still needs checking against the original filing.

Frequently Asked Questions

What should a company research dossier include?

Company basics, how it makes money, recent direction, the pressures it acknowledges, the relevant decision makers, and a short section on why this matters for your specific purpose. Keep it to one or two pages, with links to sources for anything a reader might question.

Where can I find free information on a public company?

The SEC’s EDGAR full-text search covers filings since 2001 and is free. Start with the 10-K annual report, then the DEF 14A proxy statement for executive pay and board details, and Form 8-K for significant events between annual reports.

Which part of a 10-K is most useful?

Item 1A, Risk Factors, for most research purposes. The SEC notes companies generally list these in order of importance, so the first few tell you what the company considers its biggest threats. Item 7, the MD&A, is where management explains the year in its own words.

How do I research a private company with no filings?

Use job postings to see where money and attention are going, state business registries for ownership and officers, trademark and patent filings for product direction, court records for disputes, and local trade press. You will not get audited financials, so avoid guessing revenue from headcount.

Is it legal to research a company this way?

Reading public filings, job ads, registries and court records is entirely legal. What is not legal is obtaining information by misrepresenting who you are. Under the Gramm-Leach-Bliley Act, obtaining a customer’s financial information through false statements is unlawful, and the FTC has enforced against it.

How long should building a dossier take?

Two to three hours for a solid first version on a public company, less once you know where to look. Set the limit before you start, because company research will otherwise absorb an entire day without improving the conclusion.

How often should a dossier be updated?

Date it and refresh anything older than a quarter before relying on it. Leadership changes, results and funding events all move quickly enough that a six-month-old dossier can make you look unprepared rather than informed.

Making the Target Company Research Dossier Pay Off

A research dossier for a target company is worth the time when it changes what you say, ask or decide. The raw material for public companies is free and official: the 10-K’s risk factors ranked by the company’s own sense of importance, and management’s account of the year in its own words. For private companies, hiring patterns and registry records fill much of the gap.

When the research turns into outreach, our guide to politely following up on an email with no response covers the next step.

Pick one company you care about and read only Item 1A of its latest 10-K this week. The first three risk factors will tell you more about its priorities than a morning of news searches, and it is free.
