On Friday, the renewable energy and solid waste management firm announced that Chung had disposed of 40 million shares, equivalent to 5.1% of the company’s equity.

He now holds 37.43 million shares, or 4.77%, of the company.

Chung became Cypark’s single largest shareholder in September last year when the company’s share price went below 50 sen on the back of a weak financial position and uncertain progress of its Ladang Tanah Merah waste-to-energy project in Negeri Sembilan.

However, he was then replaced as the company’s single largest shareholder by Jakel Capital Sdn Bhd, who acquired 176.65 million shares or 27.33% of the company in January this year.

Chung’s stake dropped to 10.1% following Jakel’s acquisition then.

In the meantime, the Social Security Organisation (Socso) has increased its stake to 6.74% after acquiring 2.9 million shares on the open market on Sept 13 and 1.5 million shares on Sept 14.

Socso first emerged as a substantial shareholder in Cypark in February this year.

Cypark was founded in 1999 as a waste management company. It has now branched out into renewable energy.
