Shareholder Dealing

The Company had hoped to establish and operate a matched bargain service to enable shareholders wishing to buy and sell Sphere Medical shares to find counterparties. We have received advice that because of MiFID II (the Markets in Financial Instruments Directive) it will not be possible for the Company to operate such a service.
