FORWARD-LOOKING STATEMENTS This announcement contains (or may contain) certain forward-looking statements with respect to certain of RhythmOne’s plans and its current goals and expectations relating to its future financial condition and performance and which involve a number of risks and uncertainties. RhythmOne cautions readers that no forward-looking statement is a guarantee of future performance and that actual results could differ materially from those contained in the forward-looking statements. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements sometimes use words such as 'aim', 'anticipate', 'target', 'expect', 'estimate', 'intend', 'plan', 'goal', 'believe', or other words of similar meaning. Examples of forward-looking statements include, among others, statements regarding RhythmOne's future financial position, income growth, impairment charges, business strategy, projected levels of growth in its markets, projected costs, estimates of capital expenditure, and plans and objectives for future operations of RhythmOne and other statements that are not historical fact. By their nature, forward-looking statements involve risk and uncertainty because they relate to future events and circumstances, including, but not limited to, UK domestic and global economic and business conditions, the effects of continued volatility in credit markets, market-related risks such as changes in interest rates and exchange rates, the policies and actions of governmental and regulatory authorities, changes in legislation, the further development of standards and interpretations under International Financial Reporting Standards ("IFRS") applicable to past, current and future periods, evolving practices with regard to the interpretation and application of standards under IFRS, the outcome of pending and future litigation, the success of future acquisitions and other strategic transactions and the impact of competition - a number of which factors are beyond RhythmOne's control. As a result, RhythmOne's actual future results may differ materially from the plans, goals, and expectations set forth in RhythmOne's forward-looking statements. Any forward-looking statements made herein by or on behalf of RhythmOne speak only as of the date they are made. Except as required by the FCA, AIM or applicable law, RhythmOne expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained in this announcement to reflect any changes in RhythmOne expectations with regard thereto or any changes in events, conditions or circumstances on which any such statement is based.
