Disclaimer & Cautionary Statements Additional forward-looking statements may be identified by words such as believe, expect, may, plan, potential, will, preliminary, and similar expressions, and are based on management's current beliefs and expectations. Forward-looking statements are subject to risks and uncertainties, and the Company cautions investors against placing undue reliance on such statements. Actual results may differ materially from those set forth in the forward-looking statements. Factors that could cause actual results to differ from expectations include: • Future sales are uncertain and are affected by competition, access to customers, patient access to healthcare providers, and many other factors; • The future market for the Company’s products can depend on regulatory approval of such products, which might not occur at all or when expected, and is based in part on assumptions regarding the number of patients who elect less acute and more acute treatment than the Company’s products, market acceptance of the Company’s products, and adequate reimbursement for such therapies; • The process of obtaining regulatory clearances or approvals to market a biological product or medical device from the FDA or similar regulatory authorities outside of the U.S. is costly and time consuming, and such clearances or approvals may not be granted on a timely basis, or at all, and the ability to obtain the rights to market additional, suitable products depends on negotiations with third parties which may not be forthcoming; • Whether there is full access to hospitals and healthcare provider facilities, as a continuation or escalation of access restrictions or lockdown orders resulting from the ongoing COVID-19 pandemic; and • The Company describes additional risks and uncertainties in the Risk Factors section of its most recent annual report and quarterly reports filed with the Securities and Exchange Commission. Any forward-looking statements speak only as of the date of this press release and the Company assumes no obligation to update any forward- looking statement. 3
