Beauty products and fragrance company Coty raised its buyout offer for Avon Products to $24.75 a share from its earlier, rejected price of $23.25 a share, according to a letter released Thursday.

Coty set a Monday deadline for a response to its revised, $10.69 billion offer. Avon said it would consider the bid in “due course.”

Coty also revealed that Berkshire Hathaway, the holding company of billionaire investor Warren Buffett, will contribute equity toward the offer, alongside Coty’s principal shareholder Joh. A. Benckiser and others.

J.P. Morgan Securities is financing the deal, the company said.

Pressure has been building on Avon to explore a buyout  after the door-to-door beauty company released another disappointing quarterly earnings report last week and warned of prolonged weakness in Brazil, its largest market, and the US, Dow Jones said.

Shares of Avon rose as much as four percent in premarket trade but pared some gains to add two percent leading up to the opening bell.

The latest offer price values Avon at a premium of 15 percent over its closing level of $21.60 a share Wednesday.
