Revenue and Gross Profit

Deep dive into understanding revenue recognition, growth, and gross profit analysis.

Learning Objectives

  • Understand how companies recognize revenue
  • Learn to analyze revenue growth and trends
  • Calculate and interpret gross margin
  • Compare gross margins across business types

Revenue and Gross Profit#

Revenue is where value creation begins. Understanding how to analyze a company's top line and gross profit margin is essential for evaluating any business.

Revenue isn't just "money coming in." It's specifically earned income from a company's primary business activities. Interest income, asset sales, and other non-core sources are typically reported separately.

Understanding Revenue Recognition#

When does a sale count as revenue? This is more complex than it seems.

The Key Principle#

Under accounting rules, revenue is recognized when:

  1. A product is delivered or service is performed
  2. The price is fixed or determinable
  3. Collection is reasonably assured

Watch Out

Aggressive revenue recognition is one of the most common accounting tricks. A company might record revenue before goods are shipped or services are truly complete.

Revenue Recognition Examples#

ScenarioWhen Revenue is Recognized
Product sold and shippedWhen product ships/delivers
Subscription serviceSpread over the subscription period
Long-term contractAs work progresses (percentage-of-completion)
Gift card soldWhen the card is redeemed
Software licenseDepends on terms—often upfront or over time

Analyzing Revenue Growth#

Revenue growth tells you whether the company is expanding or contracting. Here's how to analyze it:

Year-over-Year (YoY) Growth#

Compare the same quarter or year to the prior period:

YoY Growth = (Current Period - Prior Period) ÷ Prior Period × 100

Example:

  • Q3 2024 Revenue: $120 million
  • Q3 2023 Revenue: $100 million
  • YoY Growth: ($120M - $100M) ÷ $100M = 20%

What to Look For#

SignalWhat It Suggests
Consistent growthHealthy, expanding business
Accelerating growthBusiness gaining momentum
Decelerating growthPotential concerns, maturing market
Negative growthProblems that need investigation

Context Matters

A company growing revenue at 10% might sound modest, but context matters. A $500 billion company growing 10% is adding $50 billion in sales—impressive! A small startup growing only 10% might be struggling.

Organic vs. Inorganic Growth#

Not all revenue growth is created equal:

TypeWhat It MeansWhy It Matters
Organic GrowthGrowth from existing businessShows underlying business strength
Inorganic GrowthGrowth from acquisitionsMay not be sustainable

If a company grew revenue 50% but acquired a company that added 40%, the organic growth is only about 10%. Always check for acquisitions when analyzing big revenue jumps.

Revenue Mix#

Understanding where revenue comes from adds valuable context:

By Product/Service#

  • Which products are growing fastest?
  • Is the company dependent on one product?
  • Are new products gaining traction?

By Geography#

  • Domestic vs. international split
  • Which regions are growing?
  • Currency effects on international revenue

By Customer Type#

  • How concentrated are customers?
  • Is one customer a big percentage of revenue?
  • Recurring vs. one-time revenue

Customer Concentration Risk

If one customer represents more than 10-15% of revenue, the company faces significant risk if that customer leaves. Companies must disclose major customers in their filings.

Understanding Gross Profit#

Gross profit reveals the fundamental economics of what a company sells:

Gross Profit = Revenue - Cost of Goods Sold

What COGS Includes#

Business TypeTypical COGS Components
ManufacturerMaterials, direct labor, factory overhead
SoftwareHosting, data centers, customer support
RetailerInventory costs, shipping to stores
ConsultingConsultant salaries, project costs

Gross Margin Analysis#

Gross Margin = (Gross Profit ÷ Revenue) × 100

IndustryTypical Gross Margin
Software (SaaS)70-85%
Consumer Products30-50%
Retail (Grocery)20-30%
Manufacturing25-40%
Airlines15-30%

Higher gross margins aren't always "better." A grocery store with a 25% margin can still be a great business with high volume. Compare margins within the same industry.

Changes in gross margin over time tell an important story:

Improving Margins Might Mean:#

  • Better pricing power
  • Lower input costs
  • Economies of scale
  • Shift to higher-margin products

Declining Margins Might Mean:#

  • Increased competition
  • Rising input costs
  • Discounting to maintain sales
  • Shift to lower-margin products

Example Analysis#

YearRevenueCOGSGross ProfitGross Margin
2022$100M$55M$45M45.0%
2023$120M$64M$56M46.7%
2024$150M$78M$72M48.0%

This company shows healthy signs: growing revenue AND improving gross margin. The business is scaling efficiently.

Red Flags to Watch#

Revenue Red Flags#

  • Sudden revenue spike without clear explanation
  • Revenue growing much faster than the industry
  • Large "adjustments" to previously reported revenue
  • Growing faster than accounts receivable

Gross Margin Red Flags#

  • Sharp decline in gross margin
  • Margin significantly below competitors
  • Inconsistent margins quarter to quarter
  • Improvement that doesn't make business sense

Too Good to Be True

If revenue or margins look unusually good compared to competitors, dig deeper. There might be accounting choices that flatter the numbers—or worse, manipulation.

Key Takeaways

  • Revenue recognition rules determine when sales count—timing matters
  • Analyze revenue growth both year-over-year and sequentially
  • Distinguish between organic growth and growth from acquisitions
  • Gross margin shows the fundamental profitability of what a company sells
  • Compare gross margins to industry peers, not across different industries
  • Watch for trends—improving margins suggest business strength
  • Be alert to red flags like sudden spikes or unusually high margins
