  - Result: reported results
  source text: Total revenue in the fourth quarter of 2022 was $139.5 million compared to $143.8 million in the prior year quarter. The change in revenues was primarily due to lower demand for COVID-19 related services provided by CTEH. Excluding CTEH revenues of $25.8 million and $41.0 million in the fourth quarter 2022 and 2021, respectively, revenue in the fourth quarter of 2022 was $113.7 million compared to $102.8 million in the prior year quarter, an increase of 10.6% over the prior year period, mainly owing to strong organic growth in our Measurement and Analysis segment and strong growth in our Assessment, Permitting and Response businesses other than CTEH, as well as the contributions of acquisitions completed during the past twelve months. Net loss was $(10.8) million, or a loss of $(0.50) per share, in the fourth quarter of 2022 compared to a net loss of $(1.5) million, or a loss of $(0.19) per share, in the prior year quarter.

  - Result: reported results
  source text: Total revenue in the full year 2022 was $544.4 million compared to $546.4 million in the prior year. Excluding discontinued service revenues of $3.6 million and $12.1 million, respectively, total revenue in the full year 2022 was $540.8 million compared to $534.3 million in the prior year. The change in revenues was primarily driven by the expected and significantly lower COVID-19-related services provided by CTEH and the planned exit from legacy O&M contracts. Excluding CTEH revenues of $113.9 million and $231.5 million in the full year 2022 and 2021, respectively, and excluding the impact of discontinued services, revenue in the full year 2022 was $426.9 million compared to $302.8 million in the prior year, an increase of 41.0% over the prior year, primarily attributable to strong organic growth in the Measurement and Analysis and Remediation and Reuse segments and the non-CTEH businesses in our Assessment, Permitting and Response segment, as well as the contribution of acquisitions.
