Latest Financial Results

Q1 2023

Quarter Ended Mar 31, 2023


Revenue of $13.4 million, and within February 2023 guidance


Lower gross margin of 60.9%, as compared to Q1’2022, driven mainly by an increase in pump and hydraulic turbocharger revenue in the original equipment manufacturer and aftermarket channels, and a decrease PX® Pressure Exchanger® revenue in the megaproject channel.


Operating expenses grew 6% in the first quarter, as compared to Q4’2022, from growing sales and marketing expenditures in support of new businesses, and some variability in the timing of research and development expenses.


Loss from operations of $8.1 million primarily attributable to lower revenue and gross margin due to expected timing of megaproject shipments.

Dive Deeper into Energy Recovery Operations

Our energy recovery solutions have a broad range of uses across industries. Currently, our technology use and business is divided into three industries: desalination, industrial wastewater treatment, and CO2 systems.



Our company started in water desalination, where our flagship PX® Pressure Exchanger® (PX) energy recovery device today saves water desalination customers approximately USD $3.9B in energy costs annually. Our innovative products range from pumping systems to energy recovery solutions like Turbochargers and the PX.



The PX revolutionized seawater reverse osmosis (SWRO) desalination, reducing energy use by up to 60%, and is today’s industry standard in energy recovery. We are continually expanding uses to industries like industrial wastewater treatment, potable reuse, and CO2 refrigeration.
