Forward-Looking Statements

This press release includes certain disclosures which contain “forward-looking statements,” including, without limitation, statements regarding the anticipated timing of completion of the offering. You can identify forward-looking statements because they contain words such as “believes” and “expects.” Forward-looking statements are based on ACM’s current expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements are set forth in ACM’s filings with the Securities and Exchange Commission, including its registration statement on Form S-1, as amended from time to time, under the caption “Risk Factors.”
