Hertz reported an $18 million first-quarter net profit, compared with a $56.3 million net loss for the same period last year.

Adjusted net income was $93.9 million, up from $19.4 million for the first three months of 2012. Worldwide car rental revenues grew 26 percent to nearly $2.1 billion on a 23 percent increase in transaction days "largely due to the acquisition of Dollar Thrifty, partially offset by the Advantage divestiture." Rental rate revenue per transaction day rose nearly 3 percent year over year.
