ONM Environmental disputes the allegations and intends to vigorously defend the lawsuit. While the outcomes of the lawsuits are uncertain, management believes that the resolutions of these proceedings will not have a material adverse effect on the Company's financial position, results of operations, or cash flows. However, adverse outcomes could materially impact future financial results.
