July 29 (Reuters) - Health insurer Cigna Corp's quarterly revenue rose nearly 5 percent as it added new members to government-backed health plans.
The company, whose proposed takeover by bigger rival Anthem Inc is being challenged by U.S. antitrust authorities, said shareholder income fell to $510 million, or $1.97 per share in the second quarter ended June 30 from $588 million, or $2.26 per share, a year earlier.
Total revenue increased to $9.96 billion from $9.49 billion.
The company manages insurance plans for large corporations and sells health plans on the government exchanges created under Obamacare. (Reporting by Amrutha Penumudi in Bengaluru; Editing by Kirti Pandey)
