Onterris, Inc.

Except as set forth below, there have been no material changes to our risk factors from the risk factors disclosed in our 2025 Form 10-K. The risks described in our 2025 Form 10-K, in addition to the other information set forth in this Quarterly Report on Form 10-Q, are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

We may not be successful in promoting and further developing our new brand, which could adversely affect our business.

We have a limited operating history as a company and have recently changed the Company's name and rebranded all of our businesses under one new brand – Onterris. As a result, the Onterris brand is not fully established. Our industry is highly fragmented and we believe that our future success depends in part on our ability integrate our legacy brands and diverse range of environmental services that we provide under the Onterris brand. Developing awareness and strengthening our brand has required and will continue to require significant time, expense and the attention of management, and any success will depend largely on our marketing efforts and ability to provide our clients with high-quality services. We may lose customers if they do not respond favorably to the new brand or fail to recognize the new brand as a continuation of our prior business. Similarly, the rebranding may also affect our ability to recruit qualified personnel who may not be familiar with the Onterris name. We are also investing more in brand development and brand consolidation and there can be no assurances that this investment will generate additional revenues or business. If we fail to successfully maintain and continue to grow our brand through promotion and other efforts, incur excessive unanticipated expenses in attempting to promote and maintain our brands, or lose clients as a result, our business, financial condition and results of operations may be adversely affected.
