 The company Nasdaq says its latest acquisition is an important milestone in its ongoing transformation. It's bought the software firm Adenza for $10.5 billion. It's biggest acquisition ever. Now, adding Adenza means it can offer risk management, regulatory reporting, and capital market software to the financial services industry. Essentially, Nasdaq is the second biggest stock exchange in the US, but it wants to grow its services as a fintech company and become part of the fabric of the financial system. And its plan is that this will mean it can sell more ongoing services to its existing customers, and that creates a more stable revenue, one that doesn't rely on the mood of the markets to make money.
