(Bloomberg) -- Under Armour Inc.'s two-year slide has shaved more than $2.5 billion off Chief Executive Officer Kevin Plank's net worth.
Plank, who founded the sports brand, had a peak net worth of $4.2 billion in September 2015, according to the Bloomberg Billionaires Index. Under Armour shares have tumbled 75 percent since peaking at $54.70 and extended losses Tuesday after the company slashed its revenue and earnings forecast.
The drop on the gloomy sales outlook cut as much as $150 million off Plank's wealth. He is currently worth about $1.7 billion, according to the Bloomberg index.
