While 60 thrifts posted increased revenue, OTS listed 50 on its list of problem lenders, up from 43 in the fourth quarter.
Today's news follows an announcement last week that financial institutions had an $18 billion profit in the first quarter, the Federal Deposit Insurance Corporation said last week.
Thrifts were particularly hard-hit during the recession because federal rules require them to hold 65 percent of their assets in mortgages and consumer loans.
So far this year, 73 banks have failed. The failures could eclipse the 140 that collapsed in 2009, making it the most since 1992, the peak of the savings and loan crisis.
