		</p>
		<p style="margin:0pt;font-family:Times New Roman,Times,serif;font-size: 11pt;">
			<font style="display:inline;font-size:11pt;">All statements in this press release that are not historical are forward-looking statements, including, among other things, statements relating to the Company&#x2019;s expectations regarding future financial performance, backlog, sales and marketing of its products, market size and growth, the timing of FDA filings or approvals, including the DMFs of ANP, the timing of product launches, acquisitions and other matters related to its pipeline of product candidates, its share buyback program and other future events. These statements are not historical facts but rather are based on Amphastar&#x2019;s historical performance and its current expectations, estimates, and projections regarding Amphastar&#x2019;s business, operations and other similar or related factors. Words such as &#x201C;may,&#x201D; &#x201C;might,&#x201D; &#x201C;will,&#x201D; &#x201C;could,&#x201D; &#x201C;would,&#x201D; &#x201C;should,&#x201D; &#x201C;anticipate,&#x201D; &#x201C;predict,&#x201D; &#x201C;potential,&#x201D; &#x201C;continue,&#x201D; &#x201C;expect,&#x201D; &#x201C;intend,&#x201D; &#x201C;plan,&#x201D; &#x201C;project,&#x201D; &#x201C;believe,&#x201D; &#x201C;estimate,&#x201D; and other similar or related expressions are used to identify these forward-looking statements, although not all forward-looking statements contain these words. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties, and assumptions that are difficult or impossible to predict and, in some cases, beyond Amphastar&#x2019;s control.&nbsp;&nbsp;Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described in Amphastar&#x2019;s filings with the Securities and Exchange Commission. You can locate these reports through the Company&#x2019;s website at http://ir.amphastar.com and on the SEC&#x2019;s website at www.sec.gov.&nbsp;&nbsp;Amphastar undertakes no obligation to revise or update information in this press release to reflect events or circumstances in the future, even if new information becomes available or if subsequent events cause Amphastar&#x2019;s expectations to change.</font>
