He is also no stranger to controversy.
A dispute with Indian cricket's governing body early last year led Roy to briefly call-off Sahara's decade-long sponsorship of the national side.
But it is Sahara's financial business and the source of its funds that have long sparked curiosity in India. SEBI, in its uncharacteristically aggressive and public pursuit of Sahara, has questioned the authenticity of Sahara's investors.
"We challenge SEBI to find or prove even one fictitious investor," the company's ad this week said.
Last month, SEBI ordered a freeze on the assets of two Sahara companies as well as all accounts and properties in the names of Roy and three other directors of the two firms.
It wants him arrested over what it says is Sahara's failure to comply with the court's refund order.
Sahara's defiant and rambling ad was the latest in its battle with the regulator.
"For absolutely no fault of ours at all, SEBI is continuously damaging Sahara's hard earned, clean image, reputation and goodwill earned in the last 34 years, by deliberately framing wrong orders and leaking them to press and electronic channels," Roy said in the ad.
The Supreme Court is expected to hear SEBI's request seeking Roy's arrest in early April.
