How can a company increase authorised share capital?

A company can increase its authorised share capital by passing a special resolution in a general meeting, which must typically be approved by shareholders. Following this, the company must file the necessary documentation with the relevant regulatory authority, such as the Companies House in the UK or the Securities and Exchange Commission in the US, to officially register the increase. This process often involves amending the company's articles of association to reflect the new share capital amount. Additionally, the company may need to ensure compliance with any applicable laws or regulations governing share capital changes.
