May 5 (Reuters) - Jack Henry JKHY.O reported a 10.6% jump in third-quarter profit on Tuesday, underpinned by sturdy demand for its banking technology offerings.

The Monett, Missouri-based company plays a vital role in the banking space by providing small and mid-sized financial institutions with technology and payment processing services to handle their day-to-day operations.

Here are some details:

• Jack Henry's revenue jumped 8.7% to $636.2 million in the quarter from a year earlier.

• Revenue from services and support rose 10.4%, while processing revenue increased 6.6%.

• "Sales momentum remained strong, highlighted by 17 competitive core wins in the quarter, our best third quarter for new core wins in the last seven years. The sales pipeline is increasing, fueled by increased technology spending and competitive uncertainty," CEO Greg Adelson said.

• Net income was $122.9 million, or $1.71 per share, in the three months ended March 31, compared with $111.1 million, or $1.52 per share, a year earlier.

• Deconversion revenue — or one-time contract termination fee generated when a client is acquired by another financial institution — rose to $18.7 million in the quarter from $9.6 million a year earlier.
