Objectives Altium Limited is committed to a progressive increase of long-term shareholder value. Principles Altium will achieve this by considering the following factors when determining appropriate dividend payments: Altium’s growth prospects and development profile; Available cash flow and funding requirements; Capital management and needs; and Compliance with the Australian Corporations Act Guidance Application The Board of Altium Limited will aim to pay ordinary dividends each year within the range of 50-80% of net profit. Altium intends to pay dividends twice a year – an interim and a year-end dividend. It is the intention of the Altium Board to attach imputation credits to the extent that they are available. The amount of any AUD dividend will be determined using the USD exchange rate at the end of the period to which the dividend relates. The Board of Directors maintains the discretion to determine whether or not a dividend is payable and the amount of any dividend payment. Approved by the Altium Limited Board on 11 August 2022.
