• 1-for-10 reverse stock split of the Company's common stock
• CDI to common share conversion ratio changes from 1-to-1 to 10-to-1
• No anticipated change to the value of each CDI or number of CDIs held

EBR Systems, Inc. (ASX: 'EBR', 'EBR Systems', or the 'Company'), developer of the world's only wireless cardiac pacing device for heart failure, has announced that following stockholder approval, the Board has resolved to implement a 1-for-10 reverse stock split of the Company's common stock (the 'Reverse Stock Split'). The Company's outstanding CHESS Depositary Interests ('CDIs') will not be consolidated as part of the Reverse Stock Split, but rather the transmutation ratio of the CDIs to shares will change from 1-to-1 to 10-to-1. Accordingly, there is no anticipated change to the value of each CDI, nor will there be any change, except for possible minor rounding differences, to the number of CDIs that securityholders hold. The Reverse Stock Split and CDI to share conversion ratio change are expected to be effective from 27 March 2026. This corporate action is intended to increase the per-share trading price of the Company's common stock, which may help to broaden the pool of potential investors and make the stock more attractive to institutional investors.
