Concrete Pumping Holdings, Inc.

Other than as set forth below, there have been no material changes to the Risk Factors previously disclosed in our Annual Report. For a detailed discussion of the risks that affect our business, please refer to the section entitled "Risk Factors" in the Annual Report.

Changes in foreign trade policies and other factors beyond our control may adversely impact our business and financial performance.

Economic impacts from tariffs and U.S. trade policy changes, including significant tariffs on imported goods, could have direct and/or indirect material adverse effects on our business. Our operations may be indirectly impacted as they are closely tied to residential, commercial, and infrastructure construction, which may face reduced demand if tariffs increase material costs or consumer prices, leading to economic slowdowns or project cancellations resulting in reduced demand for our concrete pumping and waste management services. Additionally, our reliance on international suppliers for certain key operational equipment directly exposes us to risks of cost increases or supply constraints. Our inability to mitigate these risks or adapt to rapidly changing trade environments could adversely affect our results of operations and financial performance.
