Incitec Pivot managing director Jeanne Johns says “a lot” of shareholders support her plan to split Incitec into two separate companies but big investors said the concessions announced on Tuesday had not appeased their opposition to the plan.

Fresh delays to the demerger process were announced on Tuesday as Incitec reported a record $1.01 billion profit, a tripling of full-year dividends and a long-awaited $400 million share buyback.
