These forward-looking statements generally can be identified by phrases such as "will," "expects," "anticipates," "foresees," "forecasts," "estimates" or other words or phrases of similar import. These forward-looking statements include, without limitation, Greenlane's and KushCo's expectations with respect to future performance and anticipated financial results of the merger and the timing of completion. These statements are based on current expectations, estimates and projections about the industry, markets in which Greenlane and KushCo operate, management's beliefs, assumptions made by management and the transactions described in this presentation. While Greenlane's and KushCo's management believes the assumptions underlying the forward-looking statements and information are reasonable, such information is necessarily subject to uncertainties and may involve certain risks, many of which are difficult to predict and are beyond management's control. These risks include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; (2) the outcome of any legal proceedings that may be instituted against the parties and others following announcement of the merger agreement; (3) the inability to consummate the transaction due to the failure to obtain the requisite stockholder approvals or the failure to satisfy other conditions to completion of the transaction; (4) risks that the proposed transaction disrupts current plans and operations of Greenlane and KushCo; (5) the ability to recognize the anticipated benefits of the transaction; and (6) the amount of the costs, fees, expenses and charges related to the transaction; and the other risks and important factors contained and identified in Greenlane's and KushCo's filings with the Securities and Exchange Commission ("SEC"), such as their respective Annual Reports on Form 10-K for the fiscal year ended December 31, 2020, and August 31, 2020, respectively, any of which could cause actual results to differ materially from the forward-looking statements in this communication.
