Reading the income statement and profit margins

According to Business Acumen for Strategic Communicators: A Primer, Ch. 7–9, an income statement shows a company’s revenue and expenses and helps explain how the business makes money. To read Alphabet’s 2019 income statement, start with revenue, then subtract major expense categories to move down toward profit.

Key income statement lines

• Revenue: the total amount earned from the company’s business activities.
• Cost of revenue: similar to cost of goods sold. The source notes that for Alphabet this line is called cost of revenue, and in fiscal 2019 it was nearly $72 billion.
• Operating income: profit after subtracting operating expenses from gross profit.
• Net income: the final profit after all expenses.
• Diluted EPS: earnings per share using diluted shares outstanding.

Alphabet 2019 figures to use

From the Alphabet 2019 income statement discussed in Business Acumen for Strategic Communicators: A Primer, Ch. 7–9, use these figures:

• Revenue: about $161.9 billion
• Cost of revenue: about $71.9 billion
• Operating income: about $34.2 billion
• Net income: about $34.3 billion
• Diluted EPS: about $49.16

Step 1: Calculate gross profit and gross margin

Gross profit = Revenue − Cost of revenue

$161.9B − $71.9B = about $90.0B gross profit

Gross margin = Gross profit ÷ Revenue

$90.0B ÷ $161.9B = about 55.6%

This means Alphabet kept about 55.6 cents of gross profit from each dollar of revenue before operating expenses.

Step 2: Calculate operating margin

Operating margin = Operating income ÷ Revenue

$34.2B ÷ $161.9B = about 21.1%

This shows Alphabet generated about 21.1 cents of operating profit from each dollar of revenue.

Step 3: Calculate net margin

Net margin = Net income ÷ Revenue

$34.3B ÷ $161.9B = about 21.2%

This means Alphabet converted about 21.2 cents of each revenue dollar into final profit.

Step 4: Read diluted EPS

Business Acumen for Strategic Communicators: A Primer, Ch. 7–9 explains that EPS connects profit to the number of shares. For Alphabet in 2019, diluted EPS was about $49.16. That is the amount of earnings attributable to each diluted share.

What these margins tell you

• Gross margin shows how efficiently the core business produces revenue after direct costs.
• Operating margin shows profitability after operating expenses such as sales, marketing, research and development, and administrative costs.
• Net margin shows the overall bottom-line profitability.
• Diluted EPS shows profit on a per-share basis.

Final answers

• Gross margin: 55.6%
• Operating margin: 21.1%
• Net margin: 21.2%
• Diluted EPS: $49.16

Using the approach in Business Acumen for Strategic Communicators: A Primer, Ch. 7–9, you can read the income statement from top to bottom: revenue, cost of revenue, operating income, net income, and then EPS. That sequence makes it easier to understand both total profitability and per-share performance.
