KDS results are largely influenced by power generation needs, as well as the cycles of the oil and gas, marine, on-highway and other related industrial markets. Despite economic uncertainty, the Company expects to yield incremental demand for OEM products, parts, and services in the segment. While on-highway activity in the 2024 first quarter was driven lower by reduced business levels and delays in product deliveries for Thermo King refrigeration products, the on-highway business is expected to remain stable with improved revenues as the year progresses. The Marine repair business is also expected to remain stable with improving revenues. In power generation, strong demand is expected to continue as the need for 24/7 power and back up capabilities become more critical. In oil and gas, the Company’s manufacturing backlog is expected to provide stable levels of activity through most of 2024 which will be offset by lower conventional oil and gas work. The Company anticipates extended lead times in the near-term to continue contributing to a volatile delivery schedule of new products in 2024.
