Constellation Software stock dividends

Constellation Software dividend payout ratio: 9.75% of net profits

Recently Constellation Software has paid out, on average, around 9.75% of net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 0.22% of the current stock value.

This means that, over a year, based on recent payouts (which are sadly no guarantee of future payouts), Constellation Software shareholders could enjoy a 0.22% return on their shares in the form of dividend payments. In Constellation Software's case, that would currently equate to about C$4.00 per share.

While Constellation Software's payout ratio might seem low, this can signify that Constellation Software is investing more in its future growth.
