This communication includes certain statements that constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which reflect our current views with respect to future events and financial performance. These forward-looking statements include all statements that are not historical facts, and are generally identified by their use of such terms and phrases as “intend,” “goal,” “estimate,” “expect,” “project,” “projections,” “plans,” “potential,” “anticipate,” “should,” “could,” “designed to,” “foreseeable future,” “believe,” “think,” “scheduled,” “outlook,” “target,” “guidance” and similar expressions, although not all forward-looking statements contain such terms. This list of indicative terms and phrases is not intended to be all-inclusive.

These forward-looking statements are subject to various risks and uncertainties, many of which are outside our control, including, without limitation, the occurrence of any event, change or other circumstances that could give rise to the termination of the purchase agreement for the RUCKUS transaction; the inability to complete the proposed transaction due to the failure to satisfy any of the conditions to completion of the proposed transaction, including that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the transaction; risks related to disruption of management’s attention from the Company’s ongoing business operations due to the transaction; the effect of the announcement of the proposed transaction on the Company’s relationships, operating results and business generally; the risk that the proposed transaction will not be consummated in a timely manner; exceeding the expected costs of the transaction; our dependence on customers’ capital spending on data, communication and entertainment equipment, which could be negatively impacted by a regional or global economic downturn, among other factors; the potential impact of higher than normal inflation; concentration of sales among a limited number of customers and channel partners; risks associated with our sales through channel partners; changes to the regulatory environment in which we and our customers operate; changes in technology; industry competition and the ability to retain customers through product innovation, introduction, and marketing; changes in cost and availability of key raw materials, components and commodities and the potential effect on customer pricing and timing of delivery of products to customers; risks related to our ability to implement price increases on our products and services; risks associated with our dependence on a limited number of key suppliers for certain raw materials and components; risks related to the successful execution of cost saving initiatives; potential difficulties in realigning global manufacturing capacity and capabilities among our global manufacturing facility or those of our contract manufacturers that may affect our ability to meet customer demands for products; possible future restructuring actions; the risk that our manufacturing operations, including our contract manufacturers on which we rely, encounter capacity, production, quality, financial or other difficulties causing difficulty in meeting customer demands; our ability to incur indebtedness at acceptable interest rates or at all; our ability to generate cash to service any future indebtedness; the ability to recognize the expected benefits of the sales of the proposed transaction and prior sales transactions, including the expected financial performance of Vistance following the proposed transaction and prior sales transactions; the effect of the proposed transaction and prior sales transactions on the ability of Vistance to retain and hire key personnel and maintain relationships with its key business partners and customers, and others with whom it does business, or on its operating results and businesses generally; the response of Vistance’s competitors, creditors and other stakeholders to the proposed transaction and prior sales transactions; potential litigation relating to the proposed transaction and prior sales transactions; our ability to integrate and fully realize anticipated benefits from prior or future divestitures, acquisitions or equity investments; possible future additional impairment charges for fixed or intangible assets, including goodwill; our ability to attract and retain qualified key employees; labor unrest; product quality or performance issues, including those associated with our suppliers or contract manufacturers, and associated warranty claims; our ability to maintain effective management information technology systems and to successfully implement major systems initiatives; cyber-security incidents, including data security breaches, ransomware or computer viruses; the use of open standards; the long-term impact of climate change; significant international operations exposing us to economic risks like variability in foreign exchange rates and inflation, as well as political and other risks, including the impact of wars,
