E-cigarette maker Juul Labs Inc, which is facing regulatory scrutiny in the domestic U.S market, has raised $785.2 million in an equity and debt offering as it looks to expand globally, a regulatory filing showed.

A person familiar with the fundraising said the Friday’s filing was an expansion of the offering from earlier this month, in which the company said it had raised $325 million, and is intended to “bolster the company’s balance sheet as it continues to grow worldwide.”

The company sold convertible debt in a bridge financing which was less time consuming than an equity-financing round, the person familiar with the matter.

Juul, in which Altria Group Inc (MO.N) has a 35% ownership stake, has been launching its products in international markets like South Korea, Indonesia, and Philippines while facing intense scrutiny from regulators in the U.S. over its e-cigarettes which are widely popular among teenagers.

The Federal Trade Commission was investigating the marketing practices of the San Francisco-based company, citing a source.
