Item 2. PROPERTIES

Our worldwide headquarters and principal executive offices are located in Westbrook, Maine where we engage in manufacturing, research and development, marketing, sales, and general and administrative support functions.

Primary Facility Locations

Including the locations above, we have over 50 reference laboratories throughout the United States and over 25 reference laboratories internationally, including locations in Europe, Canada, Australia, New Zealand, Brazil, Asia, and South Africa. The majority of our reference laboratories are leased, with the remainder being owned. We also lease space in various locations worldwide for administrative support, manufacturing, sales, distribution, and storage. We believe that our leased and owned properties are generally in good condition, are well-maintained, and are generally suitable and adequate to carry on our business. We are also in the process of completing the construction of a new facility located in Scarborough, Maine to support the growth of our Water and LPD lines of business. The construction of this facility is expected to be completed in 2023.
