Annual reports, horizontal analysis, and vertical analysis
Learning goals
- Navigate an annual report and distinguish audited statements from management commentary.
- Calculate dollar/percentage horizontal changes and common-size vertical percentages.
- Connect trends with note disclosures and business context.
- Write a balanced, evidence-based interpretation without claiming certainty.
Prerequisite check
The four core statements answer different questions: performance, financial position, equity changes, and cash flows. Notes are part of the financial statements, not optional fine print.
Vocabulary
- Annual report: package containing financial statements and other corporate information.
- Management discussion and analysis (MD&A): management's explanation of results, risks, and outlook.
- Auditor's report: independent opinion on whether statements are fairly presented under the framework.
- Horizontal analysis: change across time in dollars and percentages.
- Vertical/common-size analysis: each line expressed as a percentage of a base within one period.
- Materiality: significance that could influence users' decisions.
Core idea
Analysis is a question generator. Horizontal analysis shows direction and scale over time; vertical analysis shows composition. Neither explains *why* by itself. Read accounting policies, estimates, segment data, commitments, risks, and auditor wording before reaching a conclusion.
Why this treatment makes sense
Raw dollars make companies and years hard to compare. Percentages normalize scale, but base effects can distort a percentage when the prior amount is tiny or negative. Notes reveal acquisitions, policy changes, one-time events, and estimates behind the numbers.
A repeatable method
- Confirm entity, reporting period, units, currency, framework, and auditor opinion.
- Read the business overview, MD&A, statements, significant policies, and relevant notes.
- Horizontal dollar change = current − base; percentage = change ÷ base.
- Income-statement vertical base is usually revenue; statement-of-financial-position base is total assets.
- Mark linked movements across profit, cash flow, and balance sheet.
- Seek note/business evidence and write conclusion + evidence + limitation.
Worked example
Table: Original two-year horizontal-analysis extract for Lakeshore Gear Inc.
| Item | 2025 | 2026 | Dollar change | Percentage change |
|---|---|---|---|---|
| Revenue | $500,000 | $575,000 | $75,000 | 15.0% |
| Cost of goods sold | $300,000 | $365,000 | $65,000 | 21.7% |
| Net income | $45,000 | $40,000 | −$5,000 | −11.1% |
Vertical COGS is 60.0% of revenue in 2025 and 63.5% in 2026. Net margin falls from 9.0% to 7.0%. Revenue growth did not translate into higher profit because cost of sales consumed a larger share; notes on supplier prices, product mix, discounts, inventory write-downs, or acquisitions should be investigated.
If receivables also rose 35%, faster than sales, collection quality becomes a second question. It is not proof of fictitious sales; it is evidence requiring aging and cash-collection follow-up.
Journal, ledger, and statement connection
Analysis does not generate journal entries unless it reveals a supported error or estimate change. Trace unusual percentages back to statement lines, note disclosures, ledger detail, and source documents. Preserve spreadsheet formulas and source links so another student or reviewer can reproduce the result.
Common mistakes
- Dividing horizontal change by the current year instead of the base year.
- Treating a 200% change from a tiny base as automatically material.
- Comparing companies with different years, currencies, policies, or business models without adjustment.
- Calling MD&A audited because it appears beside audited statements.
- Stating a cause that the annual report does not support.
Guided practice
Operating expenses rise from $120,000 to $138,000 while revenue rises from $600,000 to $750,000. Horizontal expense growth is 15%. Vertical expense falls from 20.0% to 18.4%, suggesting scale efficiency despite higher dollars. Both views are needed.
Independent practice
- Revenue rises $800,000 to $920,000; profit falls $64,000 to $55,200. Calculate changes and margins.
- Inventory is $120,000 and total assets $600,000. Find its common-size percentage.
- List four annual-report sections or notes to consult before recommending an investment.
- Write one cautious interpretation of sales +10% and receivables +32%.
Self-check and solutions
- Revenue +$120,000/+15%; profit −$8,800/−13.75%. Margin falls from 8.0% to 6.0%.
- 20% of total assets.
- Examples: auditor's report, statements and policies, MD&A, revenue/segment note, debt/covenant note, contingencies, subsequent events, related parties, governance.
- Collection may be slowing or sales may be concentrated late in the year; inspect aging, terms, subsequent receipts, cut-off, and customer concentration before concluding.
Retrieval practice
- What is the horizontal percentage denominator?
- What is the usual income-statement vertical base?
- Are notes part of audited financial statements?
Answers: base-year amount; revenue; yes, when covered by the auditor's report.
Exam-style application
An influencer claims “profit fell, so the company is failing.” Write a four-sentence analyst response.
Model response: Profit fell, which warrants investigation, but one change does not establish failure. Compare margins, operating cash flow, segment results, asset changes, and multi-year trends. Read notes for one-time charges, acquisitions, and policy or estimate changes, and compare with relevant peers. Conclude only after identifying both evidence and uncertainty.
Lesson summary
Annual-report analysis combines audited numbers, narrative context, notes, and reproducible calculations. Horizontal shows movement; vertical shows structure; professional interpretation separates evidence from hypothesis.
