Saudi Aramco is aiming for a valuation of $1.6 trillion to $1.7 trillion from its initial public offering (IPO), lower than $2 trillion targeted by Crown Prince Mohammed bin Salman initially. The company said it will sell 1.5% shares at a price range of 30-32 riyals. At the top end of the range, Aramco would raise up to $25.6 billion.
