How Should We Measure The Dilutive Impact Of Stock-Based Compensation

How do we measure the impact of stock-based compensation? It may not result in a cash expense but it certainly has an impact on shareholder returns.

Many tech companies nowadays use stock-based compensation to reward managers and employees. Some even pay as much as 80% of executive pay in stocks or options. I’m personally a fan of stock-based compensation for a few reasons.

A fan

For one, stock-based compensation is not a cash expense. Cash is the lifeblood of a company and is vital for a fast-growing business.

Second, stock-based compensation aligns management’s interests with shareholders. Executives and employees become shareholders themselves who are incentivised to see the stock perform well.

In addition, companies may pay executives through stock options or restricted stock units that vest over a few years. With a multi-year vesting period, executives are incentivised to see the stock do well over a multi-year period, which aligns their interests with long-term shareholders.

All these being said, stock-based compensation does create a headache for analysts: It leads to a mismatch between the company’s profit/loss and its cash flow.

Stock-based compensation is recorded as an expense in the income statement but is not a cash expense. As such, companies who use stock-based compensation end up with higher cash flow than profits.

Why adjusted earnings is not good enough

To account for the difference, some companies may decide to provide adjusted earnings. This is a non-GAAP accounting method that adjusts earnings to add back the stock-based compensation and other selected expenses.

The adjusted earnings figure is closer to the company’s actual cash flow. But I don’t think this is the best method to measure the impact of stock-based compensation.

Adjusted earnings do not take into account the dilutive impact from stock-based compensation.

Free cash flow per share may be the best metric to use

So how do we best measure the impact of stock-based compensation? Amazon.com’s founder, Jeff Bezos once said,

Percentage margins are not one of the things we are seeking to optimize. It’s the absolute dollar free cash flow per share that you want to maximize.”

I completely agree. With the growing use of stock-based compensation, earnings per share is no longer the most important factor. Free cash flow per share has become the more important determinant of what drives long term shareholder value.

This takes into account both non-cash expenses and the dilutive impact of share-based compensation. By comparing a company’s free cash flow per share over a multi-year period, we are able to derive how much the company has grown its free cash flow on a per-share basis, which is ultimately what shareholders are interested in.

Ideally, we want to see free cash flow growing much faster than the number of shares outstanding. This would lead to a higher free cash flow per share.

Conclusion

To sum up, stock-based compensation is a good way to incentivise managers to act on the interests of shareholders.

However, it creates a challenge for analysts who need to analyse the performance of the company on a per-share basis.

In the past, earnings used to be the best measure of a company’s growth. But today, with the growing use of stock-based compensation, free cash flow per share is probably a more useful metric to measure a company’s per-share growth.

By measuring the year-on-year growth in free cash flow per share, we can derive the actual growth of a company for shareholders after accounting for dilution and any other non-cash expenses.

  1. The exercise of employee stock options increases the Operating Cash Flows of a firm even though it is not an “Operational Cash Flow” per se. (Accounting Rule)
    If Free Cash Flow is defined as Operating Cash Flow – Capital Expenditure, then for Technology Firms that issue alot of employee stock options, wouldn’t Operating Cash Flows, hence Free Cash Flows be Overstated?

    1. Hi David, Thanks for reading our blog.

      Employee stock options do not technically increase the company’s operating cash flow. It just increases the diluted share count of the company.

      Consequently, it reduces the free cash flow per diluted share due to the higher number of outstanding shares when all the options are exercised. As such if you look at the company on a year-to-year basis, free cash flow growth on a per share level will be lower than free cash flow growth at the firm level if the company uses stock-based compensation.
