Mesa Labs Reports 23 Percent Increase in First Quarter Net Income

Lakewood, Colorado, August 3, 2015 – Mesa Laboratories, Inc. (NASDAQ:MLAB) (we, us, our, “Mesa” or the “Company”) today reported a 23 percent increase in net income for the first quarter ended June 30, 2015.

Highlights for the current quarter compared to the same quarter last year:

Revenues for the first quarter increased 11 percent to $18,158,000 as compared to $16,400,000 for the same quarter last year. Operating income for the first quarter increased 19 percent to $3,642,000 as compared to $3,055,000 for the same quarter last year. Net income for the first quarter increased 23 percent to $2,306,000 or $0.63 per diluted share of common stock as compared to $1,881,000 or $0.51 per diluted share of common stock for the same quarter last year.

On a non-GAAP basis, adjusted net income (which excludes the non-cash impact of amortization of intangible assets, net of tax) for the first quarter increased 20 percent to $3,137,000¹ or $0.85 per diluted share of common stock as compared to $2,612,000 or $0.71 per diluted share of common stock for the same quarter last year.

"Mesa’s fiscal 2016 is off to a good start, as reflected by the financial results for the first quarter," said John J. Sullivan, President and Chief Executive Officer. "Organic revenues growth of five percent, combined with six percent acquisition related growth, resulted in a healthy 11 percent growth of the overall business. All three of Mesa’s divisions contributed, with growth of 13 percent, eight percent and 13 percent for Biological Indicators, Instruments and Continuous Monitoring, respectively. Gross profit margin improved compared to this quarter last year by two percentage points which helped drive a 23 percent improvement in net income. I am pleased to see that the momentum we built in the business last fiscal year is carrying into our new year."

"Looking forward, I am excited about Mesa’s prospects for the remainder of the year," continued John Sullivan. “A few days after the end of the first quarter we closed the acquisition of the Infitrak business near Toronto. Infitrak’s cold chain products fit very well with Mesa’s market focus, as they are used mainly in regulated markets for maintaining quality products, and they complement our DataTrace and Continuous Monitoring product lines. We are looking forward to assisting the Infitrak team grow their business in the U.S., and we expect that the addition of this new product line will have a positive impact on Mesa’s financial performance for this year, and beyond.”

¹ The non-GAAP measures of adjusted net income and adjusted net income per diluted share are defined to exclude the non-cash impact of amortization of intangible assets, net of tax. A reconciliation between these non-GAAP measures and their GAAP counterparts is set forth in the table below, along with additional information regarding their use.

Reconciliation of Non-GAAP Measures

(Unaudited)

The non-GAAP measures of adjusted net income and adjusted net income per share presented in the reconciliation above are defined to exclude the non-cash impact of amortization of intangible assets, net of tax. The tax effect is calculated using the average corporate rate for that period multiplied by the amortization. We believe that excluding these acquisition related expenses provides the ability to understand the benefits of acquisitions based on their cash return.

We provide non-GAAP adjusted net income and non-GAAP adjusted net income per share amounts in order to provide meaningful supplemental information regarding our operational performance. Our management uses non-GAAP measures to evaluate the performance of our business and to compensate employees. This information facilitates management's internal comparisons to our historical operating results as well as to the operating results of our competitors. Since management finds this measure to be useful, we believe that our investors can benefit by evaluating both non-GAAP and GAAP results.

Our management recognizes that items such as amortization of intangible assets can have a material impact on our net income. To gain a complete picture of all effects on our profit and loss from any and all events, management does (and investors should) rely upon the GAAP consolidated statements of income. The non-GAAP numbers focus instead upon our core operating business.

Readers are reminded that non-GAAP measures are merely a supplement to, and not a replacement for, or superior to financial measures prepared according to GAAP. They should be evaluated in conjunction with the GAAP financial measures. It should be noted as well that our non-GAAP information may be different from the non-GAAP information provided by other companies.

Generally, the words "believe," "expect," "project," “anticipate,” "estimate," "intend," "will" and similar expressions identify forward-looking statements, which generally are not historical in nature.
