<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:36pt;"><font style="font-family:Times New Roman, Times, serif;font-size:10pt;"><b>Lakewood, Colorado</b>, October 5, 2017<b> &ndash;</b> Mesa Laboratories, Inc. (NASDAQ:MLAB) (we, us, our, &ldquo;Mesa&rdquo; or the &ldquo;Company&rdquo;) today announced the acquisition of all of the outstanding shares of SIMICON GMBH (&ldquo;SIMICON&rdquo;), located in greater Munich, Germany.</font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;">&nbsp;</p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:36pt;">SIMICON manufactures <font style="font-family:Times New Roman, Times, serif;font-size:10pt;">both cleaning and biological indicators, which will be integrated into Mesa&rsquo;s Biological Indicators Division. The acquisition is expected to increase division revenues by approximately six percent and to be accretive to our diluted net income per share in the first twelve months following the acquisition. The acquisition expands Mesa&rsquo;s presence in Germany and throughout Europe. Going forward, we will continue to operate from SIMICON&rsquo;s Munich facility using the existing SIMICON management, personnel and processes.</font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:36pt;"><font style="font-family:Times New Roman, Times, serif;font-size:10pt;">Biological indicators are used to assess the effectiveness of sterilization processes, including steam, gas, hydrogen peroxide, ethylene oxide and radiation, in the hospital, dental, medical device and pharmaceutical industries. SIMICON also manufactures several unique biological indicator products that Mesa does not currently offer such as disinfectant indicators for endoscope reprocessing. </font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:36pt;">Cleaning indicators <font style="font-family:Times New Roman, Times, serif;font-size:10pt;">are used to assess the effectiveness of cleaning processes, including washer-disinfectors and ultrasonic cleaners in healthcare settings. Cleaning is the critical first step performed prior to disinfection and sterilization. Debris left on an instrument may interfere with microbial inactivation and can compromise the disinfection or sterilization process. Cleaning indicators compliment the sterilization process within central sterile supply departments in hospitals. </font></p>

<p style="font-family:Times New Roman, Times, serif;font-size:10pt;margin:0pt;text-align:left;text-indent:36pt;">&ldquo;The integration of SIMICON into Mesa<font style="font-family:Times New Roman, Times, serif;font-size:10pt;">&rsquo;s Biological Indicators Division adds unique products to our sterilization portfolio enabling us to address the cleaning steps prior to sterilization and as well as addressing more price sensitive segments of the market. SIMICON is well known for providing simple to use and high-quality indicators, primarily in greater Europe. We look forward to deepening our presence in Europe, expanding our presence in the hospital segment and bringing SIMICON capabilities to North America and other markets around the globe&rdquo; stated Gary Owens, President and CEO of Mesa Laboratories.</font></p>
