Forward Looking Statements

Cautionary Note Regarding Forward-Looking Statements

This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that involve risks and uncertainties. The terms "aim," "anticipate," "believe," "contemplates," "continues," "could," "ensure," "estimate," "expect," "forecasts," "if," "intend," "likely," "may," "might," "objective," "outlook," "plan," "positioned," "potential," "predict," "probable," "project," "shall," "should," "strategy," "will," "would," and other words and terms of similar meaning and expression are intended to identify forward-looking statements. Forward-looking statements can also be identified by the fact that they do not relate strictly to historical or current facts. Such forward-looking statements are based on current expectations and involve inherent risks, uncertainties and assumptions, including factors that could delay, divert or change any of them, and could cause actual outcomes to differ materially from current expectations. Distribution Solutions Group ("DSG") can give no assurance that any goal or plan set forth in forward-looking statements can be achieved and DSG cautions readers not to place undue reliance on such statements, which speak only as of the date made. DSG undertakes no obligation to release publicly any revisions to forward-looking statements as a result of new information, future events or otherwise. Actual results may differ materially from those projected as a result of certain risks and uncertainties. Certain risks associated with DSG's business are also discussed from time to time in the reports DSG files with the SEC, including DSG's Annual Report on Form 10-K, DSG's Quarterly Reports on Form 10-Q and DSG's Current Reports on Form 8-K. In addition, the following factors, among others, could cause actual outcomes and results to differ materially from those discussed in the forward-looking statements: (i) unanticipated difficulties or expenditures relating to the mergers; (ii) the risk that stockholder litigation in connection with the mergers results in significant costs of defense, indemnification and liability; (iii) any problems arising in combining the businesses of Lawson Products, TestEquity and Gexpro Services, which may result in the combined company not operating as effectively and efficiently as expected; and (iv) the risks that DSG may encounter difficulties integrating the business of DSG and Hisco, that DSG may not achieve the anticipated synergies contemplated with respect to the transaction and that certain assumptions with respect to Hisco's business or the transaction could prove to be inaccurate.
