Forward-Looking Statements

Information set forth in this news release might include forward-looking statements that are based on management’s current estimates, beliefs, intentions, and expectations, and are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. For the CDMO Services Business Unit, there is no assurance of additional future contracts, and readers are cautioned that increased revenue is not necessarily an increase in net income or profitability as costs will likely increase as well. Launching new products is not certain, may take significant time, and is subject to risks and uncertainties beyond company control such as consumer preferences, competition landscape, government approvals required for sale or import, acceptance of benefit claims, and marketing budgets of the company and its competitors. All forward-looking statements are inherently uncertain, and actual results may be affected by a number of material factors beyond our control. Readers should not place undue reliance on forward-looking statements. BHST does not intend to update forward-looking statement disclosures other than through our regular management discussion and analysis disclosures.
