💡 What Is Market Capitalization and How Do We Calculate It?

For AstraZeneca PLC (AZN), market capitalization represents the total market value of the company’s publicly traded shares. It helps investors understand AstraZeneca’s size within the health care sector and compare it with other companies in the same industry.

In most cases, market capitalization is calculated by multiplying the current share price by the number of basic shares outstanding. Basic shares represent the actual number of common shares that currently exist, without including potential future shares from employee stock options, RSUs, warrants, or convertible securities. For example, if AstraZeneca had one million basic shares and each traded at $50, its market capitalization would be $50 million.

Formula:
Market Cap = Share Price × Shares Outstanding

The value of AstraZeneca’s market capitalization changes throughout the trading day because it mainly depends on the current share price. The number of shares outstanding typically remains stable unless the company issues new shares, buys back its own stock, or grants stock options to employees.

Based on the latest data, AstraZeneca had a market capitalization of $296.36 billion, placing it in the mega-cap category within the health care industry.
