Mesa Labs Reports Record Third Quarter Revenues and Net Income

Lakewood, Colorado, February 2, 2015 – Mesa Laboratories, Inc. (NASDAQ:MLAB) (we, us, our, “Mesa” or the “Company”) today reported record revenues and net income for the third quarter ended December 31, 2014.

Highlights: 

Revenues for the third quarter increased 36 percent to $17,830,000 as compared to $13,116,000 for the same quarter last year. Net income for the third quarter increased 38 percent to $2,403,000 or $0.66 per diluted share of common stock as compared to $1,746,000 or $0.48 per diluted share of common stock for the same quarter last year. Net income for the third quarter was impacted by an unusual item consisting of $460,000 (before tax) of expenses associated with uncollected sales tax liabilities.

Revenues for the nine months ended December 31, 2014 increased 43 percent to $52,770,000 as compared to $37,010,000 for the same period last year. Net income for the nine months ended December 31, 2014 increased 33 percent to $7,344,000 or $2.01 per diluted share of common stock as compared to $5,538,000 or $1.54 per diluted share of common stock for the same period last year. Net income for the nine months ended December 31, 2014 was impacted by the same third quarter unusual item noted above. Net income for the nine months ended December 31, 2013 was impacted by a net expense of $638,000 (before tax) of unusual items, comprised of a $1,106,000 expense for uncollected sales tax liabilities which was partially offset by a gain of $468,000 related to the sale of the Nusonics product line.

On a non-GAAP basis, adjusted net income (which excludes the non-cash impact of amortization of intangible assets, net of tax) for the third quarter increased 40 percent to $3,175,000 or $0.87 per diluted share of common stock as compared to $2,273,000 or $0.62 per diluted share of common stock for the same quarter last year. Adjusted net income for the nine months ended December 31, 2014 increased 40 percent to $9,570,000 or $2.62 per diluted share of common stock as compared to $6,847,000 or $1.91 per diluted share of common stock for the same period last year. Adjusted net income for the third quarter and the nine months ended December 31, 2014 was impacted by the same unusual items noted above.

"Mesa’s financial performance in the third quarter of fiscal year 2015 was very good," said John J. Sullivan, President and Chief Executive Officer. "I am especially pleased that organic revenue growth was 14 percent which, when combined with acquisition related growth, resulted in a 36 percent increase in revenues over this quarter last year. For the full nine months of this fiscal year Mesa’s organic growth has been a robust 11 percent. Another highlight of the quarter was that gross profit margins improved 300 basis points over last year to 62 percent. We have seen gross profit margins improve from 59 percent and 60 percent in the first and second quarters, respectively, due largely to completing several extensive business integration efforts from our previous acquisitions. Mesa’s adjusted net income (or “ANI”) also grew very well this quarter, at 40 percent, although it could have been better. If you exclude the unusual sales tax liability accrual mentioned above, ANI growth would have been 53 percent and, more importantly, reached 19 percent of revenues or $0.95 per diluted share of common stock. Overall, the third quarter performance was solid and we believe that the revenue momentum will carry into the last quarter of the fiscal year."

"Longer term, I am cautiously optimistic about Mesa’s prospects for continued revenue and profit growth," continued John Sullivan. “Tempering my optimism somewhat are the general global economic conditions, which look to be a bit uncertain, and how the collapse in the value of the Euro could further deteriorate conditions. Fortunately, only a small percent of Mesa’s revenues are denominated in Euros, so its decline will have little impact on our revenues. The larger effect of the Euro’s decline will likely be on the price competitiveness of our products in the marketplace, a situation we will monitor closely. On the plus side, a lower Euro makes European acquisitions somewhat less expensive. We continue to execute the growth strategy that we have had in place for nearly ten years. We are making new investments in R&D and Marketing to bolster organic growth, along with a new ERP system to improve the efficiency and scalability of the business. We continue our pursuit of new acquisitions to complement organic growth, with the long term goal of maintaining overall annual double-digit growth. With 43 percent revenues growth and 40 percent ANI growth through the first three quarters of the year, fiscal 2014 is shaping up to far exceed these long term goals."

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.

Financial Summary

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.

Forward Looking Statements

This press release may contain information that constitutes "forward-looking statements." Generally, the words "believe," "expect," "intend," “anticipate,” "estimate," "project," "will" and similar expressions identify forward-looking statements, which generally are not historical in nature.

Management believes that these forward-looking statements are reasonable as and when made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made.

In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and present expectations or projections.
