The purchase beefs up NYSE Euronet with stock-options trading, exchange-traded derivatives and several hundred smaller listed companies, most of which are expanding rapidly, The Wall Street Journal said Friday.

The deal is subject to shareholder and regulatory approval.

In a statement Thursday, NYSE said it would save $100 million annually within two years of closing the deal, mostly from sharing technology and staff.

The Amex has struggled to maintain market share in recent years in a battle for dominance between the NYSE and Nasdaq.
