Unilever valuation £115b?

Kraft Heinz/Warren Buffet offered to acquire Unilever for £115 billion in 2016/17.

Today the market value of Unilever is around £100 billion.

Based on Warren Buffets/Heinz valuation of £115 billion, the share today has an upside of around 15%+.

Has anything changed in terms of Unilever’s future? Can we see Unilever’s share price pick up again and justify the £115 billion valuation?
