Asset management company Aegon has said it is looking to raise $1 billion in a deal that could see it acquire U.S. technology firm Envision Capital for $5.5 billion.

The sale is valued at $2.5bn and is subject to approval by the U.K. government, which is expected to approve the deal by the end of the year, Aegon said.

The deal is expected in the coming months, and Aegon could become the second publicly traded asset management company to do so.

The company’s asset management arm, Aegis Global, has raised more than $3.5-billion through private equity funds and public offerings since it was founded in 2011.

The U.KS. government has previously said it would approve Aegon’s takeover of Envision, although the company has said that it is committed to “remaining independent and transparent”.

Aegon said in a statement on Monday that it intends to sell Envision to the British company “within the coming weeks”.

A deal between Aegis and Envision would make Aegon the third publicly traded technology company to acquire technology firms.

In 2014, British private equity firm Fidelity Group acquired British startup Blue Origin for £425m.

In January, a private equity fund owned by a prominent investor in Facebook, Andreessen Horowitz, and the tech giant Snap Inc also bought up Australian mobile-app firm TPG for $3 billion.
