Updated for the 2026-2027 CFA® Level I curriculum.
Annual and interim financial reports provide a starting point for financial statement analysis. Analysts also rely on sources that are not part of the formal financial statements but still shape how a company's performance should be read. CFA Level I tests whether you can identify these sources and explain why each one matters.
Quick Answer
Beyond annual and interim reports, analysts use sources like proxy statements, press releases, earnings calls, and investor presentations, plus external data on the economy, industry, and peer companies. These sources fill gaps that financial statements leave open, such as governance details, timely updates between reporting periods, and the broader context needed to judge whether a company's results are strong or weak relative to its environment.
Key Takeaways
Analysts use sources beyond annual and interim reports to build a complete picture of a company.
Proxy statements disclose governance details, including board composition and executive compensation.
Press releases and earnings calls provide timely updates between scheduled reporting periods.
Economic, industry, and peer company data give context for judging whether results are good or bad relative to the environment.
Third-party research and credit-rating reports add outside perspectives; assess their methods, incentives, and potential conflicts of interest.
Most of these supplementary sources are not audited, so analysts should verify key claims against the audited financial statements.
What You Need to Know for CFA Level I
The LOS asks you to describe information sources, not calculate anything from them. Expect conceptual, identification-style questions.
The core concept is recognizing which sources sit outside the annual report and interim report, and what each one adds.
You need to classify a given source correctly: proxy statement, press release, earnings call, investor presentation, or external market data.
The key boundary: this note does not cover regulatory filings, footnotes, MD&A, or audit reports. Those belong to a separate note on company-required disclosures.
The main trap is assuming these supplementary sources carry the same reliability as audited financial statements. They usually do not.
Beyond the Annual Report: What Else Analysts Use
Financial statements show what happened over a reporting period. They do not explain management's reasoning, disclose governance arrangements in detail, or tell you how the broader economy or industry is behaving. Analysts close these gaps with two broad categories of information: company-issued materials and external market context.
Company-Issued Sources
These come from the company itself but sit outside the financial statements.
Proxy statements
Public companies send proxy statements to shareholders before annual meetings. These disclose board composition, director independence, executive compensation structure, and matters up for shareholder vote. Analysts use proxy statements to assess governance quality and to understand how management incentives are structured, which can affect accounting choices.
Press releases
Companies issue press releases to announce earnings, acquisitions, management changes, or other material events. Press releases often arrive before the full interim or annual report, giving analysts an early read on results.
Earnings calls and transcripts
Management typically hosts a call after releasing quarterly or annual results. Analysts listen for tone, forward guidance, and answers to analyst questions. A transcript can reveal concerns that the financial statements alone do not show, such as a shift in customer demand or a supply chain issue.
Investor presentations
Companies prepare slide decks for investor conferences or capital markets days. These often include segment detail, strategic priorities, and management's own framing of performance, which analysts can compare against the raw financial data.
External and Market Context Sources
These come from outside the company and help analysts judge results in context.
Economic data
Analysts review indicators such as GDP growth, interest rates, and inflation to understand the macro environment a company operates in. A revenue decline looks different during a recession than during an expansion.
Industry data
Trade publications, industry associations, and market research firms publish data on industry growth rates, pricing trends, and competitive dynamics. This helps analysts judge whether a company's performance is company-specific or industry-wide.
Peer company information
Comparing a company's margins, growth, and leverage against peers helps analysts spot outliers and verify whether a result is a strength or simply average for the sector.
Third-party research and ratings
Sell-side analyst reports and credit-rating reports provide outside assessments of prospects and creditworthiness. Independence can be affected by commercial relationships or the way the work is funded. These sources can highlight risks or assumptions that the company's own disclosures do not emphasize.
Why This Distinction Matters for Analysis
Financial statements are backward-looking and periodic. Supplementary sources can be more current and provide forward-looking views. Their reliability depends on the source, incentives, methods, and evidence. Press releases and earnings calls are not subject to the same audit or regulatory scrutiny as the financial statements themselves. An analyst who treats a CEO's optimistic comment on an earnings call as equivalent to audited revenue figures is making an analytical error, not just a minor oversight.
This is also the boundary with the sibling note on regulatory filings, footnotes, management commentary, and audit reports. Those sources are formally required and tied directly to the financial statements. The sources in this note are supplementary. Some, like proxy statements, are required filings, but they are not part of the financial statements and serve a different purpose: governance disclosure rather than financial reporting.
Working Example
Scenario. An analyst is reviewing Harlow Instruments, a mid-cap industrial equipment maker, after its third-quarter results.
The 10-Q shows revenue down 4% year over year and operating margin down 150 basis points. On its own, this looks like a weak quarter.
The analyst then checks three additional sources:
Earnings call transcript
Management explains that a key customer delayed a large order into the next quarter due to its own inventory buildup. Management expects the order to close in Q4.
Industry data
A trade publication reports that industrial equipment orders across the sector fell 6% in the same quarter, driven by a broad destocking cycle among distributors.
Peer company data
Two direct competitors reported similar revenue declines of 3% to 5% in the same period.
Interpretation
Harlow's decline is consistent with broader sector weakness, which reduces the evidence for a company-specific explanation. It does not establish that the delayed order will close or that market share is stable. Check subsequent orders, comparable industry data, and the margin decline before treating management's explanation as confirmed.
Common Exam Traps
Treating earnings call commentary as audited fact
Management statements on a call are not subject to audit. Candidates sometimes assume a forward-looking statement carries the same reliability as a reported financial figure. It does not.
Confusing proxy statements with annual reports
A proxy statement covers governance and shareholder voting matters, not financial results. Candidates sometimes assume it duplicates the 10-K's financial content.
Mixing this LOS with regulatory filing sources
This note covers sources beyond the required filings. Questions about footnotes, MD&A, or audit opinions belong to the sibling note, not this one. Watch for stems that test that boundary directly.
Ignoring external context when judging performance
A candidate might read a revenue decline as purely negative without checking whether the entire industry declined. Exam questions often test whether you recognize the need for peer or industry comparison.
Assuming all supplementary sources are equally reliable
A sell-side research report and a company press release are not the same in terms of independence. Credit rating agency reports and independent research carry a different level of objectivity than company-issued materials.
Practice Question
An analyst wants to learn about a public company's board composition and executive compensation structure ahead of the shareholder vote. Which source is most appropriate?
The company's 10-Q filing
The company's proxy statement
The company's earnings call transcript
Correct Answer: B
Proxy statements are sent to shareholders before annual meetings and disclose governance details, including board composition and executive compensation. This is exactly the information the analyst needs.
Option A. The 10-Q reports quarterly financial results. It does not disclose governance or compensation structure in the detail a proxy statement provides.
Option C. The earnings call transcript focuses on financial results and management commentary on operations, not governance or compensation detail.

FAQs About Information Sources for Financial Statement Analysis
What is a proxy statement and why does it matter for financial statement analysis?
A proxy statement is sent to shareholders ahead of a vote and discloses governance details like board composition and executive pay. It matters because compensation structure can influence management's accounting and reporting incentives.
How is an earnings call different from the quarterly report itself?
A US Form 10-Q contains interim financial statements reviewed by an independent accountant; a review provides less assurance than an audit. The earnings call adds management commentary, forward guidance, and answers to analyst questions, none of which are audited.
Are press releases a reliable substitute for financial statements?
No. Press releases highlight selected results and are not subject to the same scrutiny as the financial statements. Analysts use them for timing and headline figures, then confirm details in the full report.
Why do analysts bother with economic and industry data if they already have the company's financials?
Company results only make sense in context. A decline that looks bad in isolation might be normal for the industry in that period, and economic or industry data helps make that comparison.
Does this note cover audit reports or footnotes?
No. Audit reports, footnotes, and MD&A are required disclosures tied directly to the financial statements and are covered in a separate note on regulatory filings and related disclosures.
