Stock-based compensation
Read firstHow the statements connect. Valuation without accounting is memorization.
This is a short lesson about a long argument. The accounting is settled and the economics are not, which is unusual and worth being precise about.
The accounting, which is not controversial
Since 2006, US companies have been required to expense the fair value of granted to employees. Before that, options could be granted with no charge at all, which meant a company could pay its whole workforce in options and report enormous profit. Everyone now agrees that was wrong.
The expense hits the , usually inside operating expenses. No cash moves, so the adds it straight back. The credit goes to paid-in capital, because the company issued equity. That is why total equity barely changes: falls by the after-tax expense and paid-in capital rises by the full grant.
Target Corporation expensed $281M in fiscal 2025, which is small against $6,562M of operating cash flow. At a technology company the same line can be a quarter of revenue, which is where the argument gets loud.
Target Corporation, Form 10-K for Fiscal 2025, cash flow statement.
The argument, which is not settled
The case for the add-back: cash flow statements reconcile to cash, and no cash left. Removing it would make the statement wrong at the thing it exists to do.
The case against treating the resulting figure as : the shareholder paid anyway. Instead of the company spending cash on salaries, the shareholder gave up a slice of ownership. A company that pays $100M of salaries in cash and one that pays $100M in stock have identical economics for the employees and different reported cash flow. Only one of them is issuing shares.
Watch what companies do rather than what they say. A firm that adds back stock compensation and then spends real cash buying shares back to offset the has answered the question itself: the expense was real, and it settled in cash a quarter later.
Where the cost actually lands
Treasury stock method
Test yourself
01Stock-based compensation of $20 is recorded. Walk me through the statements at a 25% tax rate.
Net income falls $15. The full $20 is added back on the cash flow statement, so operating cash flow rises $5, which is the tax saving. On the balance sheet cash rises $5, paid-in capital rises $20, retained earnings falls $15, and equity is up $5. It balances. The follow-up is whether shareholders are better off, and the answer is no: the share count went up.
02A company has 100M shares and 10M options struck at $20 with the stock at $50. What is the diluted count?
106M. Under the treasury stock method, all 10M options are exercised for $200M of proceeds, and that $200M buys back 4M shares at $50. Net new shares are 6M. If the stock were at $15 the options would be out of the money and the diluted count would stay at 100M, which is why dilution gets worse as a stock rises.
03How would you value a company that adds back a very large stock compensation charge?
Two defensible routes. Treat the expense as real and do not add it back in your free cash flow, which lowers the valuation. Or add it back and then model the share count growing, and value per share on the larger count. Both capture the cost. What is not defensible is adding it back and using today's share count forever, which is the default in a lot of published models.
Every figure in this lesson that names a company comes from Target Corporation's Form 10-K for Fiscal 2025, the year ended 2026-01-31, filed 2026-03-11. Educational material, not investment advice.
