PART I

ITEM 1. DESCRIPTION OF BUSINESS.

Introduction

Mesa Laboratories, Inc. (hereinafter referred to as the “Company” or “Mesa”) was incorporated as a Colorado corporation on March 26, 1982. The Company designs, manufactures and markets instruments and disposable products utilized in connection with industrial applications and healthcare. For industrial applications, which includes pharmaceutical, food, medical devices, and petrochemical, the Company presently markets the DATATRACE® data logging systems, NUSONICS® Concentration Analyzers, Pipeline Interface Detectors and Flow Meter products and RAVEN Biological Indicators. For healthcare applications, the Company markets Dialysate Meters used in kidney dialysis and RAVEN Biological Indicators, which are used by hospitals and dental offices to assure sterility. The Company is continually performing research and development to expand the application of its technology.

DATATRACE^® Data Loggers

The DATATRACE products are self-contained, wireless, high precision, data loggers that are used in critical manufacturing, quality control, and transportation applications. They are used to measure temperature, humidity and pressure inside a process or inside a product during manufacturing. In addition, the DATATRACE products can be used to validate the proper operation of laboratory or manufacturing equipment, either during its installation or for annual re-certifications. The product line consists of individual data loggers, a PC interface, DataTrace for Windows (DTW) reporting software and various accessories. A customer typically purchases a large number of data loggers along with a single PC interface and DTW software package. In practice, using the PC interface, the user programs the tracers to collect environmental data at a pre-determined interval, places the data loggers in the product or process, retrieves the data loggers and reads the data into a PC with the interface. After this, the user can prepare tabular and graphical reports using the DTW software. Different models of data loggers are available, including the older FRB loggers, along with the newest Micropack III line, which was introduced in March 2002. The latest generation Micropack III line is much smaller, has improved hardware and embedded software, includes a rapid optical interface, and operates over a wider temperature range. Product line sales are primarily the Micropack III line, with FRB sales being made only to customers who are adding loggers to their current inventory. The FRB product line will no longer be sold as of September 31, 2008 (service will continue to be available for several years however).

In the first quarter of fiscal 2008, in order to further expand the DATATRACE product line, The Company introduced the Datatrace Radio Frequency (RF) data logger series. DataTrace RF includes all the features and performance from previous DataTrace systems, such as the Micropack III, and adds the capability to transmit data to a PC in real time through the proprietary DTLinc RF network. The ability to view process or validation data instantly saves valuable time, and it can prevent costly processing mistakes. The DataTrace RF system allows the user to see results immediately and make appropriate decisions as necessary.

While there are a variety of different types of wireless data loggers available on the market, there are only a few that are rated as “intrinsically safe” and can operate at elevated temperatures, like the DATATRACE products. These are important differentiating factors for the DATATRACE products in the marketplace, and consequently, they are used by companies to control their most critical processes. Due to their higher accuracy and precision, along with the importance of the processes they are used to control, an important component of the DATATRACE product line is the calibration service that is provided by Mesa. Typically, each DATATRACE data logger is calibrated by Mesa’s calibration laboratory prior to shipment and then annually, for a re-certification fee, to verify its accuracy. For instance, the MPRF temperature data loggers have an operating range of -80^oC to +400^oC and can be calibrated to an accuracy of +/- 0.1^oC over a portion of this range. This allows the DATATRACE loggers to be used to conduct quality control on critical processes, such as sterilization, one of the most important applications.

RAVEN Biological Indicators

In May, 2006, the Company acquired Raven Biological Laboratories, Inc. of Omaha, Nebraska. The RAVEN product line consists of Biological Indicators (BI) and Chemical Indicators (CI) used to assess the effectiveness of sterilization processes, including steam, gas (such as ethylene oxide), and radiation. Biological Indicators consist of resistant spores of certain microorganisms which are applied on a convenient substrate. The spores are well characterized in terms of numbers and resistance to sterilization. In use, the BI is exposed to a sterilization process and then tested to determine the presence of surviving organisms. RAVEN’s line of BI’s includes both spore strips, which require post-processing transfer to a growth media, self-contained products which have the growth media already pre-packaged in crushable ampoules, industrial use BI’s, and culture media. Chemical Indicators are similar to BI’s, except that a chemical change (generally determined by color) is used to assess the exposure to sterilization conditions. BI’s and CI’s are often used together to monitor processes. RAVEN products are used to validate equipment and monitor the effectiveness of a process in any industrial or healthcare setting which uses sterilization. Key markets for RAVEN include healthcare such as dental offices and hospitals, and industrial such as medical device and pharmaceutical manufacturing.

In addition to Biological and Chemical Indicators, the Company offers Contract and Testing Services to industrial companies for the development of sterilization processes. These testing services include organism identification, population verification, sterilization process development and custom BI production.

The RAVEN Biological Indicators are distinguished in the marketplace by their high level of quality, consistency and flexibility. A variety of different formats allows the RAVEN BI to be used in many different types of processes and products. For instance, the simple spore strips are used most often in the small table-top steam sterilizers in dental offices, while a more complex self-contained BI such as the ProTest may be used by a medical device manufacturer to assure the sterility in a complex ethylene oxide sterilization process. In either case, the number of spores contained on the carrier and the resistance of the spores to the sterilization process must be well characterized in order to accurately assess the effectiveness of sterilization. During manufacturing, extensive quality control steps are used to insure that the microorganism spores are well characterized and their resistance is known following placement on the target carrier. The RAVEN products are registered medical devices manufactured under ISO 13485 controlled processes. They are developed and used according to the guidelines developed under the auspices of the Association for the Advancement of Medical Instrumentation (AAMI), which are adopted as the worldwide standard under the International Standards Organization (ISO).

Recently the Company has expanded its product line adding two (2) specialized biological indicator products. One of these products, ProTest BI Test Pack, is a significant addition to RAVEN’s offering for the domestic healthcare (hospital) market. It allows the user to immediate release certain types of sterilized materials saving the user time and money. A second product added in early 2007, ProAMP with Negative Controls, provides industrial (pharmaceutical and medical device) users with a unique and previously unseen option for sterilization monitoring and the effects of steam sterilization on the interpretation of a self-contained biological indicator. Having printed Negative Controls, the user can not only monitor their sterilization processes but also see the effects their process has on BIs themselves.

MEDICAL HEMODIALYSIS PRODUCTS

Patients with kidney failure (known as end stage renal disease, or ESRD) require the removal of toxic waste products and excess water through artificial means. This process is generally performed three times per week and is most often accomplished through the use of hemodialysis.

Hemodialysis requires the treatment to be conducted on a dialysis machine through the use of a disposable cartridge known as a dialyzer. Blood is brought extracorporally to the dialysis machine for control and monitoring and passes through the dialyzer where waste products and excess water are removed. This treatment generally lasts three to four hours. While these hemodialysis procedures can be conducted in home, the bulk of the treatments are conducted in over 4,500 clinics and hospital centers in the U.S. Currently, there are over 300,000 patients in the U.S. undergoing dialysis therapy.

In addition to the reimbursement policies of the United States Government and state agencies, the Company’s revenues from its dialysis products can be expected to be dependent upon the policies of insurance companies and kidney foundations.

Dialysate Meters

Mesa’s Dialysate Meters are instruments that are used to test various parameters of the dialysis fluid (dialysate), and the proper calibration and operation of the dialysis machine. Each measures some combination of temperature, pressure, pH and conductivity to ensure that the dialysate has the proper composition to promote the transfer of waste products from the blood to the dialysate. The meters provide a digital readout that the patient, physician or technician uses to verify that the dialysis machine is working within prescribed limits and delivering the properly prepared dialysate.

The Company manufactures two styles of Dialysate Meters; those designed for use by dialysis machine manufacturers and Biomedical Technicians and those used primarily by dialysis nurses or patient care technicians. The meters for technicians include the Models 90DX, NEO-2, and the newer 90XL. These meters are characterized by exceptional accuracy, stability, and flexibility and are used by the industry as the primary standard for the calibration of dialysis machines. The newest 90XL meter has four independent measurement channels, allowing the user to easily perform testing and calibration of multiple dialysis machines in a clinic or on the manufacturing floor.

The 90XL meter has been well received by the marketplace and already holds a dominant position in comparison to unit sales of the 90DX or NEO-2. Mesa anticipates that the marketplace will want to gradually phase out of the 90DX and the NEO-2 meters and further adopt the 90XL.

The dialysis meters designed for use by dialysis nurses are known primarily for their ease of use and include the pHoenix, Hydra, and NEO-STAT+ models. Incorporating a patented, built-in syringe sampling system, these meters are used as the final quality control check on the dialysate just prior to starting a treatment. Their design allows the nurse to quickly and easily draw a small sample of the dialysate into the meter for measurement, and management believes that they

have become the most popular meter in the point-of care testing in dialysis clinics. The pHoenix meter is the leading seller by far of the three (3) hand held meter choices.

In addition to the dialysate meters, the Company markets a line of calibration standard solutions for use in dialysis clinics for calibration and testing. These standard solutions are regularly consumed by the dialysis clinics and this, along with calibration services, represents a recurring revenue stream for the Medical product line.

NUSONICS PRODUCTS

The Company’s sonic fluid measurement product line consists of two major components:Sonic Flow Meters and Concentration Monitors. While the total market for flow meters is very large, the NUSONICS® Sonic Flow Meters best serve applications where cleanliness and resistance to corrosives are required. Specific applications where the NUSONICS® products are particularly well suited include water treatment, chemical processing and heating, ventilation and air conditioning (HVAC) applications. The Concentration Monitor component of the product line consists of Pipeline Interface Detectors and Concentration Analyzers. The Pipeline Interface Detector serves a smaller market niche while the Concentration Analyzers serve a wider variety of industry application, such as chemical, food, pharmaceutical and polymerization processes.

The NUSONICS products have been subject to strong competition in the marketplace in recent years primarily from larger, well established process control companies. Consequently, sales of NUSONICS products have decreased and currently represent less than 4% of the Company’s total revenue. Today, most sales are made to existing NUSONICS customers who are replacing or adding to their current infrastructure.

Manufacturing

The Company assembles its products at its facilities in Lakewood, Colorado and Omaha, Nebraska. The Company’s electronic products are manufactured primarily by assembling products from purchased components and testing the final products prior to release. The RAVEN products are manufactured by growing microbiological spores from raw materials, assembling the finished products through a series of process steps, and testing the finished Biological Indicators using established quality control tests.

Most of the materials and components used in the Company’s product lines are available from a number of different suppliers. Mesa generally maintains multiple sources of suppliers for most items but is dependent on a single source for certain items. Mesa believes that alternative sources could be developed, if required, for present single supply sources. Although the Company’s dependence on these single supply sources may involve a degree of risk, to date, Mesa has been able to acquire sufficient stock to meet its production requirements.

Marketing and Distribution

The Company’s domestic sales of its MEDICAL and DATATRACE products are generated by its direct sales and marketing staff, while outside the U.S., a number of distributors are utilized. The Company’s RAVEN products are distributed both directly, through a sales and marketing staff to end users and through a series of distributors both domestically and outside the U.S. International sales for all products are conducted through over 100 distributors. During the fiscal year ended March 31, 2008, approximately 74% of sales have been domestic and 26% have been international to countries throughout Europe, Africa, Australia, Asia and South America, as well as Canada and Mexico.

Sales promotions include attendance by Mesa representatives at trade shows, direct mail campaigns, internet advertising and trade journal advertising in industry related publications.

Customers of Mesa’s MEDICAL products primarily include dialysis centers and dialysis equipment manufacturers. The primary emphasis of the Company’s marketing effort is to offer quality products to the healthcare market which will aid in cost containment and improved patient well-being.

DATATRACE® customers include numerous industrial users in the food, pharmaceutical and medical device markets who utilize the products within a variety of manufacturing, quality control and validation applications. The emphasis of the Company’s marketing effort is to offer a quality product that provides a unique and flexible solution to monitoring temperature, pressure or humidity without interfering with the processing of the product.

RAVEN customers include various companies providing sterility assurance testing to the dental office market, hospitals, contract sterilizing services and various industrial users involved in pharmaceutical and medical device manufacturing. The Company’s marketing focuses on providing high quality test products in a variety of different formats, which minimize incubation and test result time.

NUSONICS® customers include various industries such as water treatment, manufacturing, HVAC and petroleum product transportation. The Company’s marketing efforts are focused on offering flow measurement and concentration monitoring in difficult environments where noninvasive monitoring techniques are required.

During the fiscal year ended March 31, 2008, one customer represented approximately 13% of the Company’s revenues and approximately 12% of the Company’s accounts receivable balance. During the fiscal year ended March 31, 2007, one customer represented approximately 14% of the Company’s revenues and approximately 12% of the Company’s accounts receivable balance.

Competition

Mesa competes with major medical and instrumentation companies as well as a number of smaller companies, many of which are well established, with substantially greater capital resources and larger research and development capabilities. Furthermore, many of these companies have an established product line and a significant operating history. Accordingly, the Company may be at a competitive disadvantage due to such factors as its limited resources and limited marketing and distribution network.

Companies with which Mesa’s dialysis products compete include Myron L Company and IBP Medical GmbH. Companies with which Mesa’s DATATRACE® data logger products compete include GE Kaye, Ellab and TMI Orion. Companies with which RAVEN’s biological indicator products compete include 3M, SGM and Steris. Companies with which Mesa’s NUSONICS® products compete include Controlotron, Badger Meter, Rosemount, and GE Panametrics.

Government Regulation

Medical devices marketed by Mesa are subject to the provisions of the Federal Food, Drug and Cosmetic Act, as amended by the Medical Device Amendments of 1976 (hereinafter referred to as the “Act”). A medical device which was not marketed prior to May 28, 1976, or is not substantially equivalent to a device marketed prior to that date, may not be marketed until certain data is filed with the FDA and the FDA has affirmatively determined that such data justifies marketing under conditions specified by the FDA. A medical device is defined by the Act as an instrument which (1) is intended for use in the diagnosis or the treatment of disease, or is intended to affect the structure of any function of the human body; (2) does not achieve its intended purpose through chemical action; and (3) is not dependent upon being metabolized for the achievement of its principal intended purpose. The Act requires any company proposing to market a medical device to notify the FDA of its intention at least ninety days before doing so, and in such notification must advise the FDA as to whether the device is substantially equivalent to a device marketed prior to May 28, 1976. As of the date hereof, the Company has received permission from the FDA to market all of its products requiring such permission.

Some of Mesa’s products are subject to FDA regulations and inspections, which may be time-consuming and costly. This includes on-going compliance with the FDA’s current Good Manufacturing Practices regulations which require, among other things, the systematic control of manufacture, packaging and storage of products intended for human use. Failure to comply with these practices renders the product adulterated and could subject the Company to an interruption of manufacture and sale of its medical products and possible regulatory action by the FDA.

The manufacture and sale of medical devices is also regulated by some states. Although there is substantial overlap between state regulations and the regulations of the FDA, some state laws may apply. Mesa, however, does not anticipate that complying with state regulations will create any significant problems. Foreign countries also have laws regulating medical devices sold in those countries, which may cause us to expend additional resources on compliance.

Employees

On March 31, 2008, the Company had a total of 113 employees, of which 110 were full-time employees. Currently, 24 persons are employed for marketing and sales, six for research and development, 71 for manufacturing and quality assurance and 12 for administration.

Additional Information

For the fiscal years ended March 31, 2008 and 2007, Mesa spent $532,000 and $392,000, respectively, on Company-sponsored research and development activities.

Compliance with federal, state and local provisions which have been enacted regarding the discharge of materials into the environment or otherwise relating to the protection of the environment has not had, and is not expected to have, any adverse effect upon capital expenditures, earnings or the competitive position of the Company. Mesa is not presently a party to any litigation or administrative proceedings with respect to its compliance with such environmental standards. In addition, the Company does not anticipate being required to expend any significant capital funds in the near future for environmental protection in connection with its operations.

The Company has been issued patents for its DATATRACE® temperature recording devices, its NUSONICS® sonic flow measurement and sonic concentration monitoring products and its pHoenix, Hydra and NeoStat+ dialysis meters and its RAVEN biological indicators. Several of these patents have now expired. Failure to obtain patent protection on the Company’s remaining products may have a substantially adverse effect upon the Company since there can be no assurance that other companies will not develop functionally similar products, placing the Company at a competitive disadvantage. Further, there can be no assurance that patent protection will afford protection against competitors with similar inventions, nor can there be any assurance that the patents will not be infringed or designed around by others. Moreover, it may be costly to pursue and to prosecute patent infringement actions against others, and such actions could interfere with the business of the Company.

Item 1A. RISK FACTORS

We face intense competition.

The markets for some of our current and potential products are intensely competitive. We face competition from companies that possess both larger sales forces and possess more capital resources. In addition, there are growing numbers of competitors for certain of our products.

Technological change could render our products obsolete or non-competitive.

The market for the Company’s products and services are characterized by rapid and substantial technological changes and swiftly evolving industry standards. As industry standards evolve rapidly, the Company may be required to develop new and competitive products to maintain or increase revenue. A competitive product requires substantial planning, design, development, and testing at the technological, product and manufacturing process stages. The Company can provide no assurance that its products will remain competitive in a rapidly changing environment. In addition, regulations and industry acceptance of new technologies may decelerate or eliminate meaningful revenue.

Acquisition of businesses could potentially decrease profit margins and decrease net income.

The Company maintains its growth strategy through product development and business and technology acquisition. Businesses acquired by the Company may provide marginal profitability or prove to be unprofitable. Additional risks include the competition among prospective buyers, the potential loss of key employees or clients of the acquired company, and the reallocation of capital from ongoing operating processes.

We may be unable to effectively protect our intellectual property.

Our ability to compete effectively depends in part on developing and maintaining the proprietary aspects of our technology and processes. We cannot assure you that the patents we have obtained, or any patents we may obtain, will provide any competitive advantages for our products. We also cannot assure you that those patents will not be successfully challenged, invalidated or circumvented in the future. In addition, we cannot assure you that competitors, many of which have substantial resources and have made substantial investments in competing technologies, have not already applied for or obtained, or will not seek to apply for or obtain, patents that will prevent, limit or interfere with our ability to make, use and sell our products either in the United States or in international markets. Patent applications are maintained in secrecy for a period after filing. We may not be aware of all of the patents and patent applications potentially adverse to our interests.

We may have product liability claims.

Our products involve a risk of product liability claims. Although we maintain product liability insurance at coverage levels which we believe are adequate, there is no assurance that, if we were to incur substantial liability for product liability claims, insurance would provide adequate coverage against such liability.

Our company faces challenges in complying with certain sections of the Sarbanes-Oxley Act.

Like many smaller public companies, our Company faces challenges in complying with the internal control requirements (Section 404) of the Sarbanes-Oxley Act. Under current frameworks, compliance in areas such as separation of duties, information system controls, etc. may prove problematic for a smaller company with limited human resources. Our Company may also be forced to incur significant expense in order to comply with the law under current control frameworks and deadlines for implementation.

Changing accounting regulations may affect operating results.

Our Operating results may be adversely affected by new laws and accounting regulations that have either been recently enacted or which are under consideration, including costs associated with implementation of Section 404 of the Sarbanes-Oxley Act.

Our operating results may fluctuate.

Our results of operations may fluctuate significantly from quarter to quarter based on numerous factors including the following:

· the introduction of new products;

· the level of market acceptance of our products;

· achievement of research and development milestones;

· timing of the receipt of orders from, and product shipment to major customers;

· timing of expenditures;

· timing of the expensing of employee stock options;

· delays in educating and training our distributors and representatives sales forces;

· manufacturing or supply delays;

· product returns;

· receipt of necessary regulatory approval;

· costs associated with implementing and maintaining compliance with the Sarbanes-Oxley Act;

· costs associated with expansion of the Company’s direct sales capabilities; and

· changes in key components by our vendors.

Changing Industry Trends May Affect Operating Results.

Various changes within the industries we serve may limit future demand for our products and may include the following:

· changes in dialysis reimbursements;

· increased availability of donated organs; and

· mergers within the dialysis provider industry have made the Company more dependent upon fewer large customers for its sales in this industry; and

· increased competition.

Our growth depends on introducing new products and the efforts of third party distributors.

Our growth depends on the acceptance of our products in the marketplace, the penetration achieved by the companies which we sell to, and rely on, to distribute and represent our products, and our ability to introduce new and innovative products that meet the needs of the various markets we serve. There can be no assurance that we will be able to continue to introduce new and innovative products or that the products we introduce, or have introduced, will be widely accepted by the marketplace, or that the companies which we contract with to distribute and represent our products will continue to successfully penetrate our various markets. Our failure to continue to introduce new products or gain wide spread acceptance of our products would adversely affect our operations.

We depend on attracting new distributors and representatives for our products.

In order to successfully commercialize our products in new markets, we will need to enter into distribution arrangements with companies that can successfully distribute and represent our products into various markets.

Our products are extensively regulated which could delay product introduction or halt sales.

The process of obtaining and maintaining required regulatory approvals is lengthy, expensive and uncertain. Although we have not experienced any substantial regulatory delays to date, there is no assurance that delays will not occur in the future, which could have a significant adverse effect on our ability to introduce new products on a timely

basis. Regulatory agencies periodically inspect our manufacturing facilities to ascertain compliance with “good manufacturing practices” and can subject approved products to additional testing and surveillance programs. Failure to comply with applicable regulatory requirements can, among other things, result in fines, suspension of regulatory approvals, product recalls, operating restrictions and criminal penalties. While we believe that we are currently in compliance, if we fail to comply with regulatory requirements, it could have an adverse effect on our results of operations and financial condition.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Mesa Laboratories, Inc. manufactures and distributes electronic measurement systems and disposable products for various niche applications, including renal treatment, food processing, medical sterilization, pharmaceutical processing and other industrial applications. Our Company follows a philosophy of manufacturing a high quality product and providing a high level of on-going service for those products. In order to optimize the performance of our Company and to build the value of the Company for its shareholders, we continually follow the trend of various key financial indicators. A sample of some of the most important of these indicators is presented in the following table.

(1) Average return on stockholder investment is calculated by dividing total net income by the average of end of year and beginning of year total stockholder’s equity.

(2) Average return on invested capital (invested capital = total assets – current liabilities – cash and short-term investments)

is calculated by dividing total net income by the average of end of year and beginning of year invested capital.

While we continually try to optimize the overall performance and trends, the table above does highlight various exceptions. Most of the indicators above are improving in the most recent fiscal year due to the addition of the Raven products in fiscal 2007. Two exceptions to the improving trends are inventory turns and the average return calculations. Improving margins along with increased inventory decreased the inventory turns slightly in fiscal 2008. Utilizing post acquisition Balance Sheets for both the beginning and ending balances of fiscal 2008 caused those balances to increase significantly in fiscal 2008 causing the average return calculations to decrease slightly in the current fiscal year.

Results of Operations

Net Sales

Net sales for fiscal 2008 increased 13 percent from fiscal 2007, and net sales for fiscal 2007 increased 49 percent from fiscal 2006. In dollars, net sales of $19,558,000 in fiscal 2008 increased $2,316,000 from $17,242,000 in 2007, and net sales of $17,242,000 in fiscal 2007 increased $5,659,000 from $11,583,000 in 2006.

Our revenues come from two main sources, which include product revenues and parts and service revenues. Parts and service revenues are derived from on-going repair and recalibration or certification of our products. The certification or recalibration of product is usually a key component of the customer’s own quality system and many of our customers operate in regulated industries, such as food processing or medical and pharmaceutical processing. For this reason, these revenues tend to be fairly stable and grow slowly over time. During fiscal years 2008, 2007 and 2006 our Company had parts and service revenue of $3,499,000, $3,333,000 and $2,982,000. As a percentage of total revenue, parts and service revenues were 18% in 2008, 19% in 2007 and 26% in 2006.

The performance of new product sales is dependent on several factors, including general economic conditions in the United States and abroad, capital spending trends and the introduction of new products. In recent years, general economic conditions have been improving, and more specifically, capital spending has been improving. New products released to the market over the past four fiscal years include the Datatrace Micropack III temperature loggers during the middle of fiscal 2003, the Datatrace Micropack III humidity and pressure loggers at the end of fiscal 2004, the 90XL Dialysate Meter for kidney dialysis was introduced late in fiscal 2006, and the Datatrace RF System was introduced in early fiscal 2009. For fiscal years 2008, 2007 and 2006 product sales for our company were $16,059,000, $13,909,000 and $8,601,000.

During fiscal 2008, sales of the Company’s medical products and services increased five percent for the fiscal year compared to the prior year period. For the year, Medical saw increased sales of meter products, disposables and service, which were partially off-set by lower sales of the discontinued dialyzer reprocessor line and lower repair part sales. Sales of our new 90XL Meter continued to progress well during fiscal 2008. In addition, we continue to maintain strong relationships with our major customers in this market.

During fiscal 2008, sales of Datatrace data logger products increased 13% compared to the prior year. For the year, DataTrace products continue to see improving trends in both new product shipments and service sales in both the domestic and international markets. Introduction of the new Micropack RF products, with their real-time reporting capabilities, is expected to further add to Datatrace product line sales in the new fiscal year.

Fiscal 2008 sales of Raven biological indicator products increased 29 percent compared to the prior year period. The Raven biological indicator products were acquired on May 4, 2006. For this reason, sales of the company’s Raven biological indicator products benefited from an extra five weeks of sales for the full year when compared to the prior year period. Over the past year, Raven has been developing its telemarketing capabilities, which are specifically focusing on penetrating the hospital segment of the market. In addition, one new private label

relationship was developed during the fiscal year with initial shipments starting during the fourth quarter of fiscal 2008. This new relationship should add further to sales growth for the Raven product line during fiscal 2009.

During fiscal 2008, sales of the Nusonics line of ultrasonic fluid measurement systems decreased by three percent. Sales of these products remain stable, but Nusonics products currently contribute less than four percent of the Company’s total sales and are not expected to grow in the future.

During fiscal 2007, sales of the Company’s medical products and services increased 20 percent for the fiscal year compared to the prior year period. Research and development efforts on our newest hand-held dialysate meter were completed during December 2005, and sales of our new 90XL Meter progressed well during the final quarter of fiscal 2006.

During fiscal 2007, sales of Datatrace data logger products increased 3 percent. In June, 2005, the company began a transition from independent manufacturer’s representatives to direct sales personnel for domestic sales of its Datatrace products. This change to our sales channels increased our selling costs but our sales levels have risen, compensating for these cost increases.

During fiscal 2007 sales of the RAVEN products increased approximately 16% from the level established prior to acquisition by the Company. Sales increases in the RAVEN line are attributable to growth in the domestic healthcare markets and international distributor sales.

During fiscal 2007, sales of the Nusonics line of ultrasonic fluid measurement systems decreased by 14 percent following three years of growth. Weakness in the NUSONICS line was the result of continuing competitive pressure, lack of new products, and a low level of sales and marketing investment. For the fiscal year 2007 Nusonics products contribute less than 5 percent of the Company’s total sales.

Cost of Sales

Cost of sales as a percent of net sales in fiscal 2008 decreased 2.5 percent from fiscal 2007 to 34.3 percent, and in fiscal 2007 increased 1.0 percent from fiscal 2006 to 36.8 percent from 35.8 percent. Most of our products enjoy gross margins in excess of 55 percent. Due to the fact that the dialysis products have sales concentrated with several companies that maintain large chains of treatment centers, the products that are sold to the renal market tend to be slightly more price sensitive than the data logging products. Also, due to the nature of the market for biological indicators, the RAVEN products produce gross margins somewhat lower than DATATRACE. Therefore, shifts in product mix toward higher sales of DATATRACE products will tend to produce lower cost of goods sold expense and higher gross margins while shifts toward higher sales of medical or RAVEN products will normally produce the opposite effect on cost of goods sold expense and gross margins.

During fiscal 2008, our Company saw reductions in costs of sales year over year with the exception of the DATATRACE line which saw a small increase of one half of one percent as a percent of DATATRACE sales. Most of the decline in costs of sales percent in the current fiscal year was attributable to an improvement in the Medical line, where cost reduction programs, price increases and improvements in freight cost recovery all contributed to the gain.

Over fiscal year 2007, our Company saw an increase in sales levels which were chiefly due to the addition of the new RAVEN products and a strong increase in dialysis product sales. This increase in sales led to an increase in cost of sales as a percent of sales as the mix of products was weighted with slightly lower margined products. During fiscal year 2006, our Company saw a shift in its mix to higher margined Datatrace product sales, which led to a decrease in cost of sales expense as a percent of sales compared to fiscal 2005.

Selling, General and Administrative

General and administrative expenses tend to be fairly fixed and stable from year-to-year. To the greatest extent possible, we work at containing and minimizing these costs. Total administrative costs were $2,420,000 in fiscal 2008, $2,075,000 in fiscal 2007 and $1,092,000 in fiscal 2006, which represents a $345,000 increase from fiscal 2007 to fiscal 2008 and a $983,000 increase from fiscal 2006 to fiscal 2007. Fiscal 2008 general and administrative costs increased due to five additional weeks of RAVEN related costs compared to the prior year along with higher accounting and consulting costs, which mostly can be attributed to the Company’s efforts to comply with the demands of Section 404 of the Sarbanes-Oxley Act of 2002. The increase in general and administrative expenses during fiscal 2007 over fiscal 2006 was directly attributable to costs associated with the RAVEN acquisition including amortization of newly acquired intangible assets and administrative costs associated with the new operation. In addition, equity compensation costs were added to fiscal 2007 due to implementation of SFAS 123(R).

Our selling and marketing costs tend to be far more variable in relation to sales, although there are various exceptions. Some of these exceptions include the introduction of new products and the mix of international sales to domestic sales. For a product line experiencing introduction of a new product, costs will tend to be higher as a percent of sales due to higher advertising development and sales training programs. Our Company’s international sales are usually discounted and recorded at the net discounted price, so that a change in mix between international and domestic sales may influence sales and marketing costs. One other major influence on sales and marketing costs is the mix of domestic dialysis product sales to all other domestic sales. Domestic dialysis product sales are made by direct telemarketing representatives, which gives us a lower cost structure, when compared to the field salesman and independent representative sales channels utilized by our other products. Through fiscal 2007 and fiscal 2008 the Company continued to focus additional resources on its sales and marketing efforts. In June of fiscal 2006, the company began a transition from independent manufacturer’s representatives to direct sales personnel for domestic sales of its Datatrace products. This change to our sales channels increased our selling costs in those years, but our domestic sales levels have been rising to compensate for these cost increases. The past year’s continuing transition to direct selling was focused on overall sales management and telemarketing resources for both the DATATRACE and RAVEN lines.

In dollars, selling costs were $2,845,000 in fiscal 2008, $2,769,000 in fiscal 2007 and $1,877,000 in fiscal 2006. As a percent of sales, selling cost were 14.5 percent in fiscal 2008, 16.1 percent in fiscal 2007 and 16.2 percent in fiscal 2006. During fiscal 2008, sales and marketing costs as a percent of sales declined. In real dollars, the DATATRACE and RAVEN costs increased due to the further expansion of our selling staff during the year along with an additional five weeks of costs for RAVEN products when compared with the previous fiscal year. The increase in selling expense during fiscal 2007 over fiscal 2006 was due chiefly to addition of the RAVEN sales and marketing team along with the associated products and sales. In addition, costs associated with the dialysis and Datatrace products also increased due chiefly to higher compensation costs. For Datatrace products, we also incurred higher travel costs due to our change to direct sales personnel during fiscal 2007.

Research and Development

Company sponsored research and development cost was $532,000 in fiscal 2008, $392,000 in fiscal 2007 and $358,000 in fiscal 2006. We are currently executing a strategy of increasing the flow of internally developed products. Most of our work during fiscal 2008 and 2007 was focused on our new Micropack RF products which we are now introducing to the market as part of our Datatrace line.

Net Income

Net income increased to $4,610,000 or $1.41 per share on a diluted basis in fiscal 2008 from $3,958,000 or $1.22 per share on a diluted basis in fiscal 2007. For the fiscal year, Mesa experienced net income growth of 16.5 percent, which was ahead of the sales growth rate of 13.4 percent. Most of this acceleration of profitability for the fiscal year can be attributed to a gain in gross profits as a percent of net sales, but was partially off-set by an increase in the income tax rate as a percent of earnings before income tax from 31.6 percent in fiscal 2007 compared to 36.5 percent in fiscal 2008. The decline in the fiscal 2007 income tax rate was due to a one time adjustment of the income tax expense that occurred in the fourth quarter of that fiscal year and was attributable to favorable income tax treatment on assets acquired in the Raven acquisition during fiscal 2007. If adjusted to the total year fiscal 2008 tax rate, net income for fiscal 2007 would have been lower by approximately $280,000 to $3,678,000. Using this adjusted fiscal 2007 net income for comparison, fiscal 2008 net income of $4,610,000 would have increased 25 percent compared to the $3,678,000 of adjusted net income in fiscal 2007.

Net income increased to $3,958,000 or $1.22 per share on a diluted basis in fiscal 2007 from $2,805,000 or $.92 per share on a diluted basis in fiscal 2006. The increase in net income during fiscal 2007 was due to higher sales. The contribution of the new RAVEN products added greatly to net income overcoming the new costs, such as amortization of intangible assets, and additional shares issued to the RAVEN shareholders to be accretive on a diluted earnings per share basis. Increased sales of dialysis and Datratrace products further helped to increase total net income during fiscal 2007.

Liquidity and Capital Resources

On March 31, 2008, we had cash and cash equivalents of $5,770,000. In addition, we had other current assets totaling $8,641,000 and total current assets of $14,411,000. Current liabilities of our Company were $1,587,000 which resulted in a current ratio of 9:1. For comparison purposes at March 31, 2007, we had cash and short term investments of $3,346,000, other current assets of $7,496,000, total current assets of $10,842,000, current liabilities of $1,469,000 and a current ratio of 7:1.

Our Company has made capital acquisitions of $207,000 in fiscal 2008. In fiscal 2007, our Company made capital acquisitions of 1,780,000 of which $1,404,000 was attributable to the purchase of the RAVEN facility during fiscal 2007.

We have instituted a program to repurchase up to 300,000 shares of our outstanding common stock. Under the plan, the shares may be purchased from time to time in the open market at prevailing prices or in negotiated transactions off the market. Shares purchased will be canceled and repurchases will be made with existing cash reserves. We do not maintain a set policy for our buyback program. Most of our stock buybacks have occurred during periods when the price to earnings multiple has been near historical low points, or during times when selling activity in the stock is out of balance with buying demand. On February 27, 2007, the Company entered into an agreement to purchase 30,000 shares of Mesa Laboratories, Inc. common stock from one of its current Board of Directors members, Mr. Paul D. Duke. Under the terms of the agreement, Mesa Laboratories, Inc. would purchase 3,000 shares of Mesa Laboratories, Inc. common stock from Mr. Duke each month beginning in March 2007 through December 2007 at a per share price equal to the volume weighted average price (VWAP) of the common stock for the previous calendar month. While Mr. Duke’s commitment to sell was binding through the entire term of the buyback period, the company and its Board retained the right to rescind the agreement at anytime during the period depending upon the circumstances existing at the time.

During the first half of fiscal 2008 the Company paid regular quarterly dividends of $.08 per share of common stock and raised the quarterly dividend to $.10 per common share of stock during the second half of the fiscal year. For fiscal year 2008, dividends totaled $.36 per common share of stock. During the first half of fiscal 2007 the Company maintained the regular quarterly dividend of $.07 per share of common stock and raised the quarterly dividend to $.08

per common share of stock during the second half of the fiscal year. In addition, the Board of Directors declared a special one time dividend of $.10 per share of common stock which was paid on December 15, 2006. For fiscal year 2007, dividends totaled $.40 per common share of stock.

Our Company invests its surplus capital in various interest bearing instruments, including money market funds, short-term treasuries and municipal bonds. All investments are fixed dollar investments with variable rates in order to minimize the risk of principal loss. In some cases, additional guarantees of the investment principal are provided in the form of bank letters of credit.

On May 4, 2006, Mesa acquired Raven Biological Laboratories, Inc. of Omaha, Nebraska. Raven is a leading designer and manufacturer of biological indicators and provider of sterilization validation services. Under the terms of the transaction, Mesa Labs acquired all of the outstanding shares of Raven for approximately $6,331,000 which was comprised of $3,081,000 cash and 223,243 shares (valued at $3,250,000) of common stock.

The Company does not currently maintain a line of credit or any other form of debt. Nor does the Company guarantee the debt of any other entity. The Company has maintained a long history of surplus cash flow from operations. This surplus cash flow has been used in the past to fund acquisitions and stock buybacks and has been partially utilized to fund past special dividends. We are actively investigating opportunities to acquire new product lines or companies, for which we may utilize cash in the future.

Contractual Obligations

At March 31, 2008 we had routine contractual obligations for open purchase orders for purchases of supplies and inventory, which would be payable in less than one year. At March 31, 2008, our company had committed approximately $550,000 for the purchase of equipment to automate certain manufacturing processes in its RAVEN operation of which approximately $145,000 had been paid at fiscal year end.

Forward Looking Statements

All statements other than statements of historical fact included in this annual report regarding our Company’s financial position and operating and strategic initiatives and addressing industry developments are forward-looking statements. Where, in any forward-looking statement, the Company, or its management, expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement of expectation or belief will result or be achieved or accomplished. Factors which could cause actual results to differ materially from those anticipated, include but are not limited to general economic, financial and business conditions; competition in the data logging market; competition in the kidney dialysis market; competition in the fluid measurement market, competition in the biological indicator market; the business abilities and judgment of personnel; the impacts of unusual items resulting from ongoing evaluations of business strategies; and changes in business strategy. We do not intend to update these forward looking statements. You are advised to review the “Item 1A. Risk Factors” of this report for more information about risks that could affect the financial results of Mesa Laboratories, Inc.

Critical Accounting Policies and Estimates

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Actual results could differ materially from those estimates.

We believe that there are several accounting policies that are critical to understanding the Company’s historical and future performance, as these policies affect the reported amounts of revenue and the more significant areas involving management’s judgments and estimates. These significant accounting policies relate to revenue recognition, research and development costs, valuation of inventory, valuation of long-lived assets and stock based compensation. These policies, and the Company’s procedures related to these policies, are described in detail below.

Revenue Recognition

We sell our products directly through our sales force and through distributors. Revenue from direct sales of our product is recognized upon shipment to the customer. Revenue from ongoing product service and repair is fully recognized upon completion and shipment of serviced product.

Research & Development Costs

Research and development activities consist primarily of new product development and continuing engineering on existing products. Costs related to research and development efforts on existing or potential products are expensed as incurred.

Valuation of Inventories

Inventories are stated at the lower of cost or market, using the first-in, first-out method (FIFO) to determine cost. The Company’s policy is to periodically evaluate the market value of the inventory and the stage of product life cycle, and record a reserve for any inventory considered slow moving or obsolete. As of March 31, 2008 and 2007 the Company had recorded a reserve of $175,000 each year.

Valuation of Long-Lived Assets

The Company assesses the realizable value of long-lived assets for potential impairment at least annually or when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated fair value is less than its carrying value. In assessing the recoverability of our long-lived assets, we must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets. In addition, we must make assumptions regarding the useful lives of these assets. As of March 31, 2008, we evaluated our long-lived assets for potential impairment. Based on our evaluation, no impairment charge was recognized.

Stock Based Compensation

The Company implemented the provisions of SFAS 123(R) effective April 1, 2006 using the modified prospective method. Under this transition method, stock based compensation expense for the year ended March 31, 2007 includes compensation expense for all stock based compensation awards granted subsequent to April 1, 2006 and previously granted awards not vested as of April 1, 2006. The Company uses the Black-Scholes valuation model to value option grants. We use historical data to estimate the expected price volatility, the expected option life and expected forfeiture rate. The risk-free rate is based on the U.S. Treasury yield in effect at the time of the grant for the estimated life of the option. The dividend yield is estimated based on the dividend payments made during the prior four quarters as a percent of average stock price for that period.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles, generally accepted in the United States of America, with no need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any viable alternative would not produce a materially different result. See

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Mesa Laboratories, Inc.

Lakewood, Colorado

We have audited the accompanying balance sheets of Mesa Laboratories, Inc. as of March 31, 2008 and 2007, and the related statements of income, stockholders’ equity, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Mesa Laboratories, Inc. as of March 31, 2008 and 2007, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies:

General - Mesa Laboratories, Inc. was incorporated under the laws of the State of Colorado on March 26, 1982, for the purpose of designing, manufacturing and marketing electronic instruments, supplies and disposable products.

Concentration of Credit Risk - Financial instruments which potentially subject the Company to concentrations of credit risk consist of money market funds, short-term investments and accounts receivable. The Company invests primarily all of its excess cash in money market funds administered by reputable financial institutions, debt instruments of the U.S. government and its agencies, adjustable rate and fixed dollar municipal debt. The Company grants credit to its customers who are located throughout the United States and foreign countries. To reduce credit risk, the Company periodically evaluates the money market fund administrators and performs credit analysis of customers and monitors their financial condition. Additionally, the Company maintains cash balances in bank deposit accounts which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts.

Cash Equivalents - Cash equivalents include all highly liquid investments with an original maturity of three months or less.

Short-term investments - Short-term investments consist of U.S Treasury bills and municipal bonds and are classified as “available for sale.” Short-term investments are carried in the financial statements at cost, which approximates fair value.

Accounts Receivable - At the time the accounts are originated, the Company considers a reserve for doubtful accounts based on the creditworthiness of the customer. The provision for uncollectible amounts is continually reviewed and adjusted to maintain the allowance at a level considered adequate to cover future losses. The allowance is management’s best estimate of uncollectible amounts and is determined based on historical performance that is tracked by the Company on an ongoing basis. The losses ultimately incurred could differ materially in the near term from the amounts estimated in determining the allowance.

Inventories - Inventories are stated at the lower of cost or market, using the first-in, first-out method (FIFO) to determine cost. The Company’s policy is to periodically evaluate the market value of the inventory and the stage of product life cycle, and record a reserve for any inventory considered slow moving or obsolete. As of March 31, 2008 and 2007 the Company had recorded a reserve of $175,000, against slow moving inventory.

Property, Plant and Equipment - Property, plant and equipment is stated at acquisition cost. Depreciation and amortization is provided using the straight-line method over the estimated useful lives of three to thirty-nine years.

MESA LABORATORIES, INC.

NOTES TO FINANCIAL STATEMENTS

(CONTINUED)

Goodwill and Other Intangible Assets – Goodwill, which resulted from the acquisitions of Nusonics, Datatrace, Raven and Automata, is no longer subject to amortization, and is tested annually for impairment in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 142 “Goodwill and Intangible Assets.” Certain intangible assets including patents, non-compete agreements and customer relationships were recognized as part of the Raven acquisition and are amortized over their estimated useful lives which range from 3 to 16 years.

Valuation of Long-Lived Assets - The Company assesses the realizable value of long-lived assets for potential impairment at least annually or when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated fair value is less than its carrying value. In assessing the recoverability of our long-lived assets, we must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the respective assets. In addition, we must make assumptions regarding the useful lives of these assets. As of March 31, 2008, we evaluated our long-lived assets for potential impairment. Based on our evaluation, no impairment charge was recognized.

Revenue Recognition - Revenue is recognized when persuasive evidence of an arrangement exists, when title and risk of ownership passes, the sales price is fixed or determinable, and collectibility is probable. The Company recognizes revenues at the time products are shipped. Revenue from ongoing product service and repair is fully recognized upon completion and shipment of serviced product.

Sales to distributors are made at their net discounted price. This net discounted price is net of any volume pricing that may be available. Customers who may be unsure of the appropriateness of our products for their application are offered demonstration equipment prior to purchase, thus no return rights are extended. Products are built to customer order and no price protections are offered.

Other than normal and customary on-going customer service, the Company does not have any post shipment contractual obligations to its customers, such as installation, training, etc.

Research & Development Costs - Costs related to research and development efforts on existing or potential products are expensed as incurred. Research and development costs for the fiscal years ended March 31, 2008 and 2007 were $532,000 and $392,000 each year, respectively.

Accrued Warranty Expense - The Company provides limited product warranty on its products and, accordingly, accrues an estimate of the related warranty expense at the time of sale.

Advertising Costs - Advertising costs are expensed as incurred. Advertising costs for the years ended March 31, 2008 and 2007 were $212,000 and $225,000, respectively.

Income Taxes - The Company accounts for income taxes under the liability method, which requires an entity to recognize deferred tax assets and liabilities. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years.

MESA LABORATORIES, INC.

NOTES TO FINANCIAL STATEMENTS

(CONTINUED)

Stock Based Compensation - In December 2004 the FASB issued Statement of Financial Accounting Standard No. 123(R), Share Based Payment (SFAS 123(R)). SFAS 123(R) is a revision of FASB Statement No. 123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends SFAS 95, and its related implementation guidance. SFAS 123(R) focuses primarily on accounting for transactions in which an entity obtains employee services through share-based payment transactions. SFAS 123(R) requires an entity to measure the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award at the date of grant. The cost is to be recognized over the period during which an employee is required to provide services in exchange for the award. SFAS 123(R) also requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an operating cash flow as prescribed under the prior accounting rules. This requirement reduces net operating cash flows and increases net financing cash flows in periods after adoption. Total cash flow remains unchanged from what would have been reported under prior accounting rules.

The Company implemented the provisions of SFAS 123(R) effective April 1, 2006 using the modified prospective method. Under this method, the Company recognizes compensation expense on a straight-line basis over the vesting period for all stock-based awards granted on or after April 1, 2006, and for previously granted awards not yet vested as of April 1, 2006. Under the provisions of SFAS 123(R), the company recognizes stock-based compensation net of an estimated forfeiture rate, resulting in the recognition of compensation cost for only those shares expected to vest. Prior to the adoption of SFAS 123(R), the Company followed the intrinsic value method in accordance with APB 25 to account for the issuance of stock incentives to employees and directors. Accordingly, no compensation expense was recognized relating to stock-based awards prior to April 1, 2006. Results of operations for periods prior to fiscal 2007 have not been restated to reflect recognition of stock-based compensation expense.

Earnings Per Share - Basic earnings per share is calculated using the average number of common shares outstanding. Diluted earnings per share is computed on the basis of the average number of common shares outstanding plus the effect of outstanding stock options using the treasury stock method, which totaled 113,000 and 78,000 additional shares in 2008 and 2007, respectively.

Basic net income per common share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per common share is computed using the treasury stock method to compute the weighted average common stock outstanding assuming the conversion of potential dilutive common shares.

MESA LABORATORIES, INC.

NOTES TO FINANCIAL STATEMENTS

(CONTINUED)

The following table presents a reconciliation of the denominators used in the computation of net income per common share - basic and net income per common share - diluted for the twelve month periods ended March 31, 2008 and 2007:

	Twelve Months Ended
	March 31,
	2008		2007

Net income available for shareholders	$	4,610,000	$	3,958,000

Weighted avg. outstanding shares of common stock	3,168,000		3,156,000
Dilutive effect of stock options	113,000		78,000

Common stock and equivalents	3,281,000		3,234,000

Earnings per share:
Basic	$	1.46	$	1.25
Diluted	$	1.41	$	1.22

For the twelve months ended March 31, 2008 and 2007, 2,000 outstanding stock options each year were excluded from the calculation of diluted earnings per share because the exercise prices of the stock options were greater than or equal to the average price of the common shares, and therefore their inclusion would have been anti-dilutive.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fair Value of Financial Instruments - The carrying amount of financial instruments including cash and cash equivalents, accounts receivable, short-term investments, accounts payable and accrued expenses approximated fair value as of March 31, 2008 because of the relatively short maturity of these instruments.

Recently Issued Accounting Pronouncements - In September 2006, the FASB issued SFAS 157, Fair Value Measurement (SFAS 157). The standard provides guidance for using fair value to measure assets and liabilities. SFAS 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. The statement is effective for the Company beginning April 1, 2009; however, early adoption is permitted. The adoption of SFAS 157 has not had a material impact on the Company’s financial statements.

MESA LABORATORIES, INC.

NOTES TO FINANCIAL STATEMENTS

(CONTINUED)

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities,” (“SFAS No. 159”). SFAS 159 establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. Previously, accounting rules required different measurement attributes for different assets and liabilities that created artificial volatility in earnings. SFAS No. 159 helps to mitigate this type of accounting-induced volatility by enabling companies to report related assets and liabilities at fair value, which would likely reduce the need for companies to comply with detailed rules for hedge accounting. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007, though early adoption is permitted. The adoption of SFAS No. 159 did not have an impact on the Company’s financial statements.

In March 2007, the FASB ratified Emerging Issues Task Force No. 06-11, (“EITF Issue No. 06-11”), “Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards.” EITF 06-11 requires companies to recognize the income tax benefit realized from dividends or dividend equivalents that are charged to retained earnings and paid to employees for nonvested equity-classified employee share-based payment awards as an increase to additional paid-in capital. EITF 06-11 is effective for fiscal years beginning after September 15, 2007. The Company does not expect EITF 06-11 will have a material impact on its financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51.” SFAS 160 establishes accounting and reporting standards for noncontrolling interests in subsidiaries. This statement requires the reporting of all noncontrolling interests as a separate component of stockholders’ equity, the reporting of consolidated net income (loss) as the amount attributable to both the parent and the noncontrolling interests and the separate disclosure of net income (loss) attributable to the parent and to the noncontrolling interests. In addition, this statement provides accounting and reporting guidance related to changes in noncontrolling ownership interests. Other than the reporting requirements described above which require retrospective application, the provisions of SFAS 160 are to be applied prospectively in the first annual reporting period beginning on or after December 15, 2008. The Company currently has no noncontrolling interests, thus the adoption of FAS 160 is expected to have no impact on our consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations,” (FAS 141R), which replaces FASB Statement No. 141. FAS 141R establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and the goodwill acquired. The Statement also establishes disclosure requirements which will enable users to evaluate the nature and financial effects of the business combination. FAS 141R is effective as of the beginning of an entity’s fiscal year that begins after December 15, 2008, which will be our year beginning April 1, 2009. We are currently evaluating the potential impact, if any, of the adoption of FAS 141R on our consolidated financial statements.

2. Acquisition of Raven:

Mesa Laboratories, Inc. on May 4, 2006, acquired Raven Biological Laboratories, Inc. of Omaha, Nebraska. Raven, a privately held company, is a leading designer and manufacturer of biological indicators and provider of sterilization validation services. Under the terms of the transaction, Mesa Labs has acquired all of the outstanding shares of Raven for approximately $6,331,000 which was comprised primarily of the following:

Cash paid to shareholders	$	2,991,000
Mesa stock paid to shareholders	3,250,000
Acquisition costs	196,000
Liabilities assumed	84,000
Less cash acquired from Raven	(190,000		)
	$	6,331,000

The purchase price was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date:

Current assets	$	1,386,000
Property, plant and equipment	663,000
Other assets	39,000
Identifiable intangible assets:
Patents	37,000
Non-compete agreements	382,000
Customer relationships	2,608,000
Trade name	123,000
Goodwill	1,093,000
	$	6,331,000

The allocation of the purchase price was based, in part, on a third-party valuation of the fair value of identifiable intangible assets, and certain property, plant and equipment. The cost of the identifiable intangible assets will be amortized on a straight-line basis over periods of 3 to 16 years.

The results of Raven’s operations have been included in the consolidated financial statements commencing from the acquisition date. The pro forma effect of the acquisition on the combined results of operations as if the acquisition had been completed on April 1, 2006 is as follows:

5. Goodwill and Other Intangible Assets:

As of March 31, 2008, goodwill amounted to $5,301,000, which includes the addition in fiscal 2007 of $1,093,000 for the acquisition of Raven Biological Laboratories, Inc., all of which is deductible for tax purposes. Prior to the Raven acquisition, goodwill amounted to $4,208,000, which resulted from the acquisitions of Nusonics, Datatrace and Automata. The Company completed its annual impairment tests during the fourth quarters of fiscal 2008 and 2007 and determined there was no impairment.

Other intangible assets (all of which are being amortized except projects in process) are as follows:

	As of March 31, 2008
	Carrying Amount		Accumulated Amortization		Net		Useful Life
Patents	$	37,000	$	4,000	$	33,000	16 years

Amortization expense was $502,000 in 2008 and $460,000 in 2007.

Estimated amortization expense for the fiscal years 2009 to 2013 is $502,000, $385,000, $375,000, $375,000, and $375,000 respectively.

6. Income Taxes:

Effective April 1, 2007, we adopted the provisions of the Financial Accounting Standards Board (“FASB”) Interpretation No. 48, Accounting of Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109. Under FIN 48, we must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. We measure the tax benefits recognized in the consolidated financial statements from such a position based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax law and regulations change over time and may result in changes to our subjective assumptions and judgments which can materially affect amounts recognized in our Consolidated Balance Sheets and Consolidated Statements of Operations. The result of the reassessment of our tax positions in accordance with FIN 48 did not have a material impact on our consolidated financial statements. Our federal tax returns for all years after 2003 and our state tax returns after 2002 are subject to future examination by tax authorities for all our tax jurisdictions. We recognize interest and penalties related to income tax matters in other income (expense) and corporate, general and administration expenses, respectively.

7. Stock Repurchase:

In November, 2005, the Company’s Board of Directors approved a program to repurchase up to 300,000 shares of its outstanding common stock. Under the program, shares may be purchased from time to time in the open market at prevailing prices or in negotiated transactions off the market. Shares purchased will be cancelled and repurchase of shares will be funded through existing cash reserves.

8. Employee Benefit Plan:

The Company adopted a 401(k) plan effective January 1, 2000. Participation is voluntary and employees are eligible to participate at age 21 and after six months of employment with the Company. The Company matches 50% of the employee’s contribution up to 6% of the employees salary. A participant vests in the Company’s contributions at a rate of 25% per year, fully vesting at the end of the participant’s fourth year of service. For the Raven employees, eligibility begins at age 21 and one year of employment with the Company. The Company matches 100% of the employee’s contribution up to 3% of the employees salary, and 50% of contributions above 3% up to 5% of salary. A participant vests in the Company’s contributions immediately. The Company contributed $129,000 to the plans for fiscal 2008 and $118,000 for fiscal 2007.

9. Stockholders’ Equity:

The State of Colorado has eliminated the ability of Colorado corporations to retain treasury stock. As a result, the Company reduced common stock to its average share value and further reduced retained earnings for the remainder of the cost of treasury stock acquired in each fiscal year. In the most recent fiscal year, management estimated that approximately 10% of the price paid for repurchased shares was attributable to the original purchase of common stock, while the remainder was charged to retained earnings.

The Company has adopted incentive stock option plans for the benefit of the Company’s key employees, excluding its outside directors. Under terms of the plans, options are granted at an amount not less than 100% of the bid price of the underlying shares at the date of grant. Options are exercisable for a term of five years and, during such term, may be exercised as follows: 25% after each year, and 100% anytime after the fourth year until the end of the fifth year.

On October 3, 1996, the Company adopted a nonqualified performance stock option plan for the benefit of the Company’s outside Directors. The plan provides that the outside Directors will receive grants to be determined and approved by the Company’s inside Directors and not to exceed 20,000 options per year per director. Under the terms of the plan, the options are exercisable for a term of ten years and, during such term are exercisable as follows: 25% after each year, and 100% anytime after the fourth year until the end of the tenth year. The purchase price of the common stock will be equal to 100% of the closing price of the common stock on the over-the-counter market on the date of grant. Effective March 24, 2006, this plan has expired, and no new grants can be made.

On October 21, 1999, the Company adopted a new stock compensation plan. The purpose of the plan is to encourage ownership of the Common Stock of the Company by certain officers, directors, employees and certain advisors of the Company in order to provide incentive to promote the success and business of the Company. A total of 300,000 shares of Common Stock were reserved for issuance under the plan and are subject to terms as set by the Compensation Committee of the Board of Directors at the time of grant. On October 18, 2004, the shareholders approved an amendment to the plan to reserve an additional 200,000 shares of Common Stock for issuance under the plan.

On December 8, 2006, the Company adopted a new stock compensation plan. The purpose of the plan is to encourage ownership of the Common Stock of the Company by certain officers, directors, employees and certain advisors of the Company in order to provide incentive to promote the success and business of the Company. A total of 400,000 shares of Common Stock were reserved for issuance under the plan and are subject to terms as set by the Compensation Committee of the Board of Directors at the time of grant.

All option plans have been approved by the stockholders of the Company.

10. Stock based compensation:

Effective April 1, 2006, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment” (SFAS 123(R)) which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors. SFAS 123(R) supersedes our previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB 25).

We adopted the modified prospective transition method of applying SFAS 123(R) which requires the application of the standard as of April 1, 2006 and requires us to record compensation cost related to unvested stock options as of April 1, 2006, by recognizing the unamortized grant date fair value of these awards over the remaining service periods of those awards with no change in historical reported earnings. Awards granted after April 1, 2006 are valued at fair value in accordance with the provisions of SFAS 123(R) and recognized on a straight line basis over the service periods of each award. We estimated forfeiture rates for the year based on historical experience.

Stock-based compensation expense was reflected as general and administrative expense in the statements of operations.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model (Black-Scholes). We use historical data to estimate the expected price volatility, the expected option life and expected forfeiture rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. The dividend yield is calculated based upon the dividend payments made during the prior four quarters as a percent of the average stock price for that period. The following assumptions were used to estimate the fair value of options granted during fiscal 2008 and 2007 using the Black-Scholes model:

	2008	2007
Stock options:
Volatility	33-36%	23-39%
Risk-free interest rate	4.0-5.1%	4.6-5.2%
Expected option life (years)	5-10	5-10
Dividend yield	2.1-2.9%	2.4-3.7%

11. Segment Data:

The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information. FAS 131 designates the internal reporting that is used by management for making operating decisions and assessing performance as the source of the Company’s reportable segments. FAS 131 also requires disclosure about products and sources, geographic areas and major customers.

ITEM 9A(T). CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to reasonably ensure that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered in this annual report on Form 10-K. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of such period to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that material information relating to our company is made known to management, including our Chief Executive Officer and Chief Financial Officer, particularly during the period when our periodic reports are being prepared.

Management’s Report on Internal Control over Financial Reporting

Mesa Laboratories, Inc. management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, our management concluded that our internal control over financial reporting was effective as of March 31, 2008.

This annual report does not include an attestation report of the company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the company’s registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the company to provide only management’s report in this annual report.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during our fourth quarter of the year ended March 31, 2008 that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Procedures and Internal Control over Financial Reporting

It should be noted that any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system will be met. In designing and operating a control system, one must consider the potential benefits of controls relative to their costs and the reality of limited resources available to allocate to control activities, particularly in smaller companies. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events and there can be no assurance that any control will meet its objectives under all potential future conditions. Because of such inherent limitations in any control system, there can be no absolute assurance that control issues, misstatements, and/or fraud will be prevented or detected.
