In exchange for the $200 million, Blackstone will receive preferred stock that can convert to common stock in three years if certain conditions are met. It will also receive two board seats.
The preferred stock will have a 6 percent cash dividend rate and is convertible into shares of common stock at a conversion price of $14.50 per share.
The shoemaker also said late on Sunday that the company's chief executive, John McCarvel, plans to retire in April and will also give up his seat on Crocs' board.
"We will recruit a new CEO who will work with the reconstituted board to refine our short-term and long-term strategic plans, which will include a sharper focus on earnings growth with less emphasis on top-line growth," Chairman Thomas Smach said in a statement.
Crocs, which is known for its colorful clogs, intends to use the Blackstone investment to help pay for a $350 million stock repurchase it expects to launch in the first quarter.
Established in 2002, Crocs sells its shoes, made out of a proprietary closed-cell resin it calls Croslite and which are offered in more than 300 four-season footwear styles in some 125 countries, according to its website.
Crocs posted a 2 percent decline in sales for the third quarter, hurt by weakness in the Americas and Japan. The company said it saw less discretionary spending for footwear, apparel and other consumer goods in the United States.
The company now expects fourth-quarter revenue to be at the low end of the previously provided outlook range of $220 million and $225 million, while it expects loss per share to be near 23 cents.
Analysts, on an average, were expecting fourth quarter loss per share of 20 cents on revenue of $222.3 million, according to Thomson Reuters I/B/E/S.
Moelis & Co LLC was the financial advisor and Perkins Coie LLP provided legal counsel for Crocs.
Blackstone was advised by Piper Jaffray & Co while Simpson Thacher & Bartlett LLP acted as legal counsel in connection with the investment.
