Manufacturing revenues amounted to $1.15 million in first-quarter 2022, down 28.3% year over year. The year-over-year decline was due to significant product delivery delays requested by customers as well as continuing delayed shipments of raw materials and supplies to Aerex. Services revenues were $4.74 million for first-quarter 2022, up 33.9% year over year. The improvement was due to an increase in both plant design revenues and operating and maintenance revenues.
