Satyam Computer Services was founded in 1987 and went public in 1991. In 2009, the company's chairman Ramalinga Raju resigned after admitting to a corporate fraud where he had falsified Satyam's accounts for years, inflating cash and bank balances. An investigation found that Raju had misstated over $1 billion in liabilities and cash to hide financial issues. In the aftermath, Tech Mahindra acquired Satyam and rebranded it as Mahindra Satyam to restore credibility and focus on industries like telecom, manufacturing, and banking.
