Share-Based Compensation (SBC) (also known as stock-based compensation) is a way for companies to pay their team not with cold, hard cash, but with a piece of the pie: company equity. Instead of a check, employees, executives, or directors receive rewards like stock options, restricted stock units (RSUs), or access to an employee stock purchase plan (ESPP). The logic is twofold. First, it helps companies, especially cash-strapped startups in tech or biotech, attract top talent without draining their bank accounts. Second, it's meant to align the interests of employees with those of shareholders. If the company does well and its stock price rises, everyone wins. While it doesn't involve a direct cash payout, SBC is a very real expense. Under accounting rules (GAAP), companies must estimate the value of these equity awards and record it as an expense on the income statement, which reduces their reported net income.
At first glance, SBC seems like a smart way to motivate a team. But for a shrewd investor, it’s a critical area to investigate, often revealing a lot about a company's financial health and management's attitude toward shareholders. There are two main reasons to be cautious.
The most significant issue with SBC is dilution. When a company issues new shares for its employees, the total number of shares outstanding increases. Think of the company as a pizza. SBC is like cutting the pizza into more slices. Even if the pizza gets a little bigger (the company grows), your original slice represents a smaller portion of the whole pie. This means your ownership stake in the company shrinks, and your share of future profits gets smaller. A little dilution from a fast-growing company can be acceptable if the value created by motivated employees far outweighs the cost. However, excessive or relentless SBC can be a red flag, indicating that existing shareholders are consistently losing ground. As an investor, you are paying for these employee rewards through the dilution of your own holdings.
This is where things get tricky. Because SBC is a non-cash expense, companies add it back to their net income on the statement of cash flows to calculate cash from operations. This is technically correct, as no cash left the building. However, many companies take this a step further. They heavily promote an “adjusted” or non-GAAP earnings figure, which conveniently excludes the SBC expense. This makes their profitability look much better than it actually is. Don't be fooled. As the legendary investor Warren Buffett has argued for decades, SBC is a genuine expense. Giving an employee something of value (a share of the company) is a cost of doing business, just like paying a salary. Ignoring it is like pretending your rent isn't a real cost just because you paid it with a valuable painting instead of cash. Always be skeptical of adjusted earnings figures that exclude SBC.
Analyzing SBC isn't about rejecting any company that uses it. It's about understanding its magnitude and judging whether it's reasonable.
