Share Dilution: When Growth Costs More Than It Earns

Net income up 20% reads well in a press release. Check the share count before you celebrate. If the company issued 10% more shares over the same year, each existing share owns a smaller slice, and your part of that profit grew by less than half the headline rate.

That gap is the cost of the new shares. Sometimes it’s worth paying. A company that sells stock to fund a factory that later earns far more than the dilution cost has used its owners’ money well. When shares go out year after year with nothing to show for them, the dilution is simply a cost.

Where new shares come from

There are two main routes. The first is a stock offering, where the company sells new shares for cash, and it tends to show up in the financing section of the cash flow statement and in the news. The second is stock-based compensation: shares and options handed to employees as part of their pay.

Stock-based pay is a real expense. It is counted among the expenses on the income statement, gets added back on the cash flow statement because no cash left the building, and then turns up as a higher share count as the grants vest. A company can report healthy operating cash flow partly because it pays staff in stock, and that flatters the cash figures while the dilution lands on you.

Growth bought with thinner margins

Revenue can also be bought with price cuts, heavy marketing or a sales force that costs more than it brings in. The sales line looks great. The profit line can shrink at the same time.

A five-point fall in margin, which is 500 basis points, wiped out all the growth and then some. Early in a company’s life, spending ahead of revenue can be a deliberate choice that pays off later when the costs level out and the margin widens again. You want to see that happen. If the margin keeps sliding year after year while management keeps promising scale, the business may simply cost more to run than its customers will pay, and no amount of extra revenue fixes that on its own.

Growth that burns cash

The third drain is cash. Free cash flow is what’s left of operating cash flow after capital expenditures, both found on the cash flow statement, and it measures what the business generates after paying to keep itself running and growing.

Take a hypothetical company that generates $20 million of operating cash flow and spends $50 million on capital projects. Free cash flow is negative $30 million. That hole has to be filled every year from cash in the bank, from borrowing, or from selling shares, which brings you back to dilution.

Negative free cash flow is normal for a young company building capacity. The danger is dependence. A business that needs outside money every year to keep growing is betting that lenders and stock buyers will stay willing, and when credit tightens or its share price falls hard, it either slows down or raises money on worse terms, often by selling more shares at a lower price, which dilutes existing owners even more than the same raise would have at the higher price.

The four checks

Run these on any growth company before you decide what it’s worth:

• The operating margin, year by year. Flat or rising is what you want to see.
• Free cash flow, across several years. Is it improving as revenue grows?
• The diluted share count trend. A few percent a year compounds, just as the compound annual growth rate lesson showed for revenue.
• Stock-based compensation as a share of revenue. Rising is a warning.

All four come from the three statements, which the lesson on reading the financial statements walks through. None of them needs anything a filing on EDGAR won’t give you for free.

Once you know how much of the growth actually reaches each share, you can ask the last question in the course, which the lesson on how much to pay for growth takes up: what price does that growth justify?
