The Australian Securities and Investments Commission (AISC) imposed an additional AU$150 million capital charge on ASX (ASX:ASX) by June 30, 2027, until the company resets its transformational Accelerate program to meet the Commission's requirement, according to a Monday statement by the Commission.

The Commission's decision follows a June inquiry by the AISC that identified shortcomings in the company's governance, capability, risk management, and culture.

The AISC also proposed that ASX ensure its Clearing and Settlement Facility boards have the necessary capability, resources, and authority to fulfil their duties, the statement said.

Along with the Reserve Bank, the Commission will uplift the joint supervisory model for the company, the statement added.

In a separate Monday filing with the Australian bourse, the company said it will cut its dividend payout ratio to the bottom end of 75% to 85% of underlying net profit after tax, for the next three dividends.

The company's earlier payout policy range was between 80% to 90%.

It also said it operates a discounted dividend reinvestment plan for at least the next three dividends.

Shares of the company fell 6% and earlier hit a 52-week low.
