Mesa Labs Acquires GKE-GmbH

Complementary Sterilization Indicators and Healthcare Channels to Mesa’s SDC Platform

Lakewood, Colorado, October 16, 2023 – Mesa Laboratories, Inc. (NASDAQ:MLAB) (“Mesa”, “we”, “us” or “our”), a global leader in the design and manufacturing of life science tools and critical quality control solutions, today announced the completed acquisition of GKE-GmbH’s sterilization indicators business and its accredited, independent testing lab SAL GmbH. Additionally, Mesa has entered into a definitive agreement to purchase GKE’s Chinese sales entity, Beijing GKE Science & Technology Co. LTD (“GKE China”). The total purchase price for the acquisition of the three entities is €85M (of which €5M is associated with GKE China), which is subject to customary purchase price adjustments and holdbacks. Collectively these three entities are referred to as “GKE”. The all-cash transactions were or will be funded with proceeds from our credit facility and cash on hand. The GKE China transaction is expected to be completed during our third quarter ending December 31, 2023, and is subject to customary conditions, including receipt of applicable Chinese regulatory approvals.

GKE is headquartered in Waldems, Germany and is engaged in the business of developing concepts for monitoring, cleaning, and sterilization processes as well as the development, manufacture, validation, and distribution of biological, chemical, and cleaning process indicators. The Waldems GKE facility will serve as Mesa’s center of excellence for the chemical indicator and healthcare business. The three GKE entities are expected to add €19-€20 million of revenues during the first 12 months of complete ownership and deliver mid-single digit organic revenues growth over the next several years. Excluding the impact of purchase accounting and integration expenses, we expect gross profit as a percentage of revenues to be in line with our existing SDC business and adjusted operating income¹ as a percentage of revenues to approach 37%-40% for the same first 12 months of complete ownership.

“GKE brings a highly competitive portfolio of sterilization indicators to protect patient safety across global healthcare markets which includes hospitals, clinics, and dental services. The combination of GKE’s strength in chemical indicators and healthcare focused sales channels will complement our SDC division’s strength in biologic indicators and life science channels placing both businesses in a position for robust long-term growth. We believe that The Mesa Way approach to continuous improvement will help the GKE team to continue to rapidly scale both commercially and operationally. GKE will be Mesa’s 7th acquisition within our SDC division and we expect the combined businesses to rapidly create additional value for our collective customers,” said Gary Owens, President and Chief Executive Officer of Mesa.

“The combination of GKE with Mesa’s SDC division creates one of the world’s largest sterilization and cleaning process indictor companies. Combined GKE and Mesa will have over 200 distribution partners serving customers in over 80 countries. Mesa is the ideal match to continue GKE’s mission to provide technical solutions to our customers”, said Dr. Ulrich Kaiser, Managing Director of GKE.
