Overview

During the second quarter of 2005, we realigned our lines of business into two business segments, the Apparatus and Instrumentation Business segment and our Capital Equipment Business segment. Our business had previously been arranged in a single segment.

In July 2005, we announced plans to divest our Capital Equipment Business segment. The decision to divest this business was based on the fact that market conditions for the Capital Equipment Business segment had been such that this business did not meet our expectations and the decision to focus our resources on our Apparatus and Instrumentation Business segment. As a result, we began reporting our Capital Equipment Business segment as a discontinued operation in the third quarter of 2005. In November 2007, we completed the sale of the assets of our Genomic Solutions Division and the stock of our Belgian subsidiary, MAIA Scientific, both of which were part of our Capital Equipment Business Segment, to Digilab, Inc. In September 2008, we completed the sale of assets of our Union Biometrica Division including our German subsidiary, Union Biometrica GmbH, representing at that time the remaining portion of our Capital Equipment Business Segment. Accordingly, unless otherwise indicated, the discussion of our business is focused on our continuing operations, which constitute our Apparatus and Instrumentation businesses.

From 1997 to 2008, the revenues from our continuing operations grew from $11.5 million to $88.0 million, an annual compounded growth rate of approximately 20%. Since the second half of 2005, when we made the

decision to divest the Capital Equipment Business segment, we refocused our resources on our core apparatus and instrumentation business, which has been the cornerstone to our success over the last decade.

In March 2008, we outlined five major initiatives. These initiatives included:

† the launch of a new major Harvard Apparatus catalog during February 2008;

† the launch of Panlab products into US markets;

† the signing of a new contract with GE Healthcare and the full launch of our new microliter spectrophotometer;

† the launch of new 2-D electrophoresis products through our Hoefer subsidiary; and

† the consolidation of business functions to reduce operating expenses.

We made the following progress on these five initiatives during the year:

† We launched our new major catalog in February 2008 with a second mailing tranche in April 2008. During the fourth quarter of 2008, we also launched a Panlab catalog and an electrophysiology catalog featuring our Warner and BTX product lines. The addition of Panlab products to the Harvard Apparatus business unit portfolio of products has been well received.

† We entered into a new distributor contract with GE Healthcare in April 2008, which led to healthy sales of our new microliter spectrophotometer in the first half of the year, however sales of our other spectrophotometers through GE Healthcare declined significantly. We are currently working with GE Healthcare to reverse the decline in this business.

† We made significant progress consolidating certain business functions; in particular, we consolidated the marketing and administrative functions of Hoefer into the Harvard Apparatus business and consolidated the complete operations of Asys into our Biochrom business. While we have reduced expenses at both Hoefer and Asys, at Hoefer the decline in electrophoresis revenue through GE Healthcare partially offset these savings.

† While we did launch the new Hoefer 2-D electrophoresis products in the second quarter of 2008, the uptake of this product has been slower than expected.

The goals of these initiatives were to improve our organic growth rates and drive operational efficiencies.

For 2009, our goal is to drive organic growth through both new product development and direct marketing. The key elements of the growth plan for 2009 are the following:

† the launch of Biochrom US, a new subsidiary, to drive growth of the Biochrom spectrophotometer and Asys plate reader products in the US market;

† the full year impact of Warner and Panlab catalogs mailed at the end of 2008;

† the continued search engine optimization of our websites;

† the launch of a new catalog to drive the Hoefer/SciePlas electrophoresis products in Q2;

† the launch of a new product in Q2; and

† the development of new products that will have little impact on 2009 revenue but should position us well for future growth.

We expect that these initiatives will drive organic growth in the low single digit range in 2009.

We also expect to continue the program of operational improvements we began last year and have recently announced the consolidation of part of our electrophoresis operations that we expect will save approximately $0.005 per share on a full year basis and about half that amount during 2009. We anticipate that we will incur restructuring costs associated with this consolidation of approximately $0.5 million in the first half of 2009.

Accordingly, we remain committed to our goal of high revenue and profit growth through a combination of organic growth, tuck under acquisitions and operational improvements. While we expect the initiatives discussed above will positively impact our business, the success of these initiatives is subject to a number of factors including the fluctuations in foreign exchange rates, the current economic and financial crisis and their impact on our customers, the competitiveness of our new products, the strength of our intellectual property underlying these products, the success of our marketing efforts and those of our distributors and the other factors described under the heading "Item 1A. Risk Factors".

Generally, management evaluates the financial performance of its operations before the effects of stock compensation expense, restructuring charges, certain one-off items and before the effects of purchase accounting and amortization of intangible assets related to our acquisitions. Our goal is to develop and sell products that improve life science research and as such, we monitor our operating metrics and when appropriate, effect organizational changes to leverage infrastructure and distribution channels. These changes may be effected as a result of various events, including acquisitions, the worldwide economy, general market conditions and personnel changes.

During 2003, we entered into a $20.0 million credit facility with Brown Brothers Harriman & Co. On December 1, 2006, we amended the terms of the credit facility. The amended credit facility expires on December 1, 2009. We are working with our existing banks to obtain a new facility so adequate financing at appropriate maturities will continue to be available for acquisitions. Over the past several months, the global credit markets have suffered through a liquidity contraction. We believe that the lack of liquidity in the market at large has not had a significant impact on us or on our current negotiations with our banks to obtain a new credit facility, with the exception that we believe the new facility will be at prevailing interest rates. Prevailing interest rates currently exceed the rates we pay under the existing credit facility at this time, by an estimated 0.5%. We expect to secure this extended debt financing on a timely basis to avoid being constrained in pursuing our acquisition strategy. See Note 10-Long-Term Debt.

Historically, we have funded acquisitions with debt, capital raised by issuing equity and cash flow from operations. In order to continue the acquisition portion of our growth strategy beyond what our current cash balances and cash flow from operations can support, we will need to raise more capital, either by incurring additional debt, issuing equity or a combination.

In the table below, we provide an overview of selected operating metrics.

Revenues. We generate revenues by selling apparatus, instruments, devices and consumables through our catalog, our direct sales force, our distributors and our website.

For products primarily priced under $10,000, every one to three years, we typically distribute a new, comprehensive catalog initially in a series of bulk mailings, first to our existing customers, followed by mailings to targeted markets of potential customers. Over the life of the catalog, distribution will also be made periodically to potential and existing customers through direct mail and trade shows and in response to e-mail and telephone inquiries. From time to time, we also intend to distribute catalog supplements that promote selected areas of our catalog or new products to targeted subsets of our customer base. Future distributions of our comprehensive catalog and our catalog supplements will be determined primarily by the incidence of new product introductions, which cannot be predicted. Our end user customers are research scientists at pharmaceutical and biotechnology companies, universities and government laboratories. Revenue from catalog sales in any period is influenced by the amount of time elapsed since the last mailing of the catalog, the number of catalogs mailed and the number of

new items included in the catalog. We launched our latest comprehensive catalog in February 2008, with approximately 900 pages and approximately 60,000 copies printed. Revenues from direct sales to end users, derived through our catalog and the electronic version of our catalog on our website, represented approximately 30% and 31% of our revenues for the years ended December 31, 2008 and 2007, respectively.

Products sold under brand names of distributors including GE Healthcare, are typically priced in the range of $5,000-$15,000. They are mainly scientific instruments like spectrophotometers and plate readers that analyze light to detect and quantify a very wide range of molecular and cellular processes or apparatus like gel electrophoresis units. We also use distributors for both our catalog products and our higher priced products, for sales in locations where we do not have subsidiaries or where we have distributors in place for acquired businesses. For the years ended December 31, 2008 and 2007, approximately 54% and 59%, respectively, of our revenues were derived from sales to distributors.

For the years ended December 31, 2008 and 2007, approximately 85% and 87%, respectively, of our revenues were derived from products we manufacture. The remaining 15% and 13%, respectively, of our revenues for the years ended December 31, 2008 and 2007, were derived from complementary products we distribute in order to provide the researcher with a single source for all equipment needed to conduct a particular experiment. For the years ended December 31, 2008 and 2007, approximately 60% and 58%, respectively, of our revenues were derived from sales made by our non-U.S. operations. A large portion of our international sales during both 2008 and 2007 consisted of sales to GE Healthcare (formerly Amersham Biosciences), the distributor for our spectrophotometers. GE Healthcare distributes these products to customers around the world, including to many customers in the United States, from its distribution center in Upsalla, Sweden. As a result, we believe our international sales would have been a lower percentage of our revenues if we had shipped our products directly to our end-users. Changes in the relative proportion of our revenue sources between catalog sales, direct sales, and distribution sales are primarily the result of a different sales proportion of acquired companies.

Cost of product revenues. Cost of product revenues includes material, labor and manufacturing overhead costs, obsolescence charges, packaging costs, warranty costs, shipping costs and royalties. Our cost of product revenues may vary over time based on the mix of products sold. We sell products that we manufacture and products that we purchase from third parties. The products that we purchase from third parties have higher cost of goods sold because the profit is effectively shared with the original manufacturer. We anticipate that our manufactured products will continue to have a lower cost of product revenues as a percentage of revenues as compared with the cost of non-manufactured products for the foreseeable future. Additionally, our cost of product revenues as a percent of product revenues will vary based on mix of direct to end user sales and distributor sales, mix by product line and mix by geography.

Sales and marketing expenses. Sales and marketing expense consists primarily of salaries and related expenses for personnel in sales, marketing and customer support functions. We also incur costs for travel, trade shows, demonstration equipment, public relations and marketing materials, consisting primarily of the printing and distribution of our approximately 900 page catalog, supplements and various other specialty catalogs, and the maintenance of our websites. We may from time to time expand our marketing efforts by employing additional technical marketing specialists in an effort to increase sales of selected categories of products in our catalog. We may also from time to time expand our direct sales organizations in an effort to concentrate on key accounts or promote certain product lines.

General and administrative expenses. General and administrative expense consists primarily of salaries and other related costs for personnel in executive, finance, accounting, information technology and human relations functions. Other costs include professional fees for legal and accounting services, non-inventory related restructuring costs, facility costs, investor relations, insurance and provision for doubtful accounts.

Research and development expenses. Research and development expense consists primarily of salaries and related expenses for personnel and capital resources used to develop and enhance our products and to support collaboration agreements. Other research and development expense includes fees for consultants and outside service providers, and material costs for prototype and test units. We expense research and development costs as incurred. We believe that investment in product development is a competitive necessity and plan to continue to make these investments in order to realize the potential of new technologies that we develop, license or acquire.

Stock compensation expenses. On January 1, 2006, we adopted SFAS No. 123 (revised) 2004), Share-Based Payment, which requires us to recognize compensation expense for all share-based payment awards made to employees and directors including employee stock options and employee stock purchases related to the Employee Stock Purchase Plan ("employee stock purchases"). We adopted SFAS No. 123(R) using the modified prospective transition method, which requires the application of the accounting standard as of January 1, 2006, the first day of our fiscal year 2006. Stock-based compensation expense recognized under SFAS No. 123(R) for the year ended December 31, 2008 was $2.0 million and $9,000 in our continuing operations and discontinued operations, respectively. Stock-based compensation expense recognized under SFAS No. 123(R) for the year ended December 31, 2007 was $2.3 million and $0.1 million in our continuing operations and discontinued operations, respectively. Stock-based compensation expense recognized under SFAS No. 123(R) for the year ended December 31, 2006 was $1.9 million and $0.2 million in our continuing operations and discontinued operations, respectively. This stock-based compensation expense was related to employee stock options and the employee stock purchase plan and was recorded as a component of cost of product revenues, sales and marketing expenses, general and administrative expenses, research and development expenses and discontinued operations.

Results of Operations

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Revenues.

Revenues increased $4.6 million, or 5.6%, to $88.0 million for the year ended December 31, 2008 compared to $83.4 million for the same period in 2007. The Company's Panlab subsidiary, acquired during the fourth quarter of 2007, accounted for a $6.8 million increase in revenues. A strengthening of the U.S. dollar during 2008 had a $3.0 million negative impact on revenues during the year. Excluding the effect of currency rate changes, the Company's Harvard Apparatus business reported a slight revenue decrease (less than 1%), and the Biochrom business reported 3% organic growth compared with 2007. Biochrom's organic growth came primarily from sales of its new microliter spectrophotometer product.

Cost of product revenues.

Cost of product revenues increased $2.7 million, or 6.3%, to $45.9 million for the year ended December 31, 2008 from $43.2 million for the year ended December 31, 2007. The Company's Panlab subsidiary was acquired in the fourth quarter of 2007, and only that quarter's operating results were included in the Company's results in 2007. Therefore, Panlab accounted for a $4.4 million increase in cost of product revenues during 2008. At Biochrom, the additional production costs of its organic sales growth were in large part offset by cost savings derived from consolidating the Asys manufacturing operation into Biochrom's site. The effects of a strengthened U.S. dollar reduced 2008 cost of product revenues by $1.9 million compared with 2007. Gross profit as a percentage of revenues decreased to 47.9% for the year ended December 31, 2008 compared with 48.3% for the same period in 2007. The decrease in gross profit as a percentage of revenues was primarily due to certain inventory write-downs related to our consolidation plan. The Panlab business, acquired in October 2007, has lower than average gross margins than the Company's consolidated average but the effect of Panlab's lower margins on the Company's overall gross margin was offset by improved mix across our other businesses. See Note 9 of our consolidated financial statements-Restructuring and Other Exit Costs.

Sales and marketing expense.

Sales and marketing expenses increased $0.6 million, or 6.0%, to $11.0 million for the year ended December 31, 2008 compared to $10.4 million for the year ended December 31, 2007. The inclusion of a full year of sales and marketing costs at our Panlab subsidiary caused an increase of $0.8 million in 2008. That increase was partially offset by the effects of changes in currency exchange rates, which reduced sales and marketing expenses by $0.1 million in 2008 compared with 2007.

General and administrative expense.

General and administrative expenses increased $0.3 million, or 2.0%, to $15.1 million for the year ended December 31, 2008 compared with $14.8 million for the year ended December 31, 2007. The inclusion of a full year's results of our Panlab subsidiary caused an increase in general and administrative expenses of $0.6 million in 2008. Additionally, the implementation of the Company's shareholder rights plan during 2008 cost $0.1 million. Those increases were partially offset by the effects of changes in currency exchange rates, which reduced general and administrative expenses by $0.3 million in 2008 compared with 2007.

Research and development expense.

Research and development expenses were $4.0 million, an increase of $0.3 million for the year ended December 31, 2008 compared to $3.7 million for the year ended December 31, 2007. The increase in research and development expenses was primarily due to expenses of $0.5 million at Panlab, partially offset by the effects of currency rate changes.

Amortization of intangible assets.

Amortization of intangibles was $2.0 million and $1.8 million for the years ended December 31, 2008 and 2007, respectively.

Other income (expense), net.

Other expense, net, was $0.8 million for the year ended December 31, 2008 compared to other income net of $35,000 for the year ended December 31, 2007. Included in other expense, net for the year ended December 31, 2008 was $0.5 million in costs related to an asset write-off and $0.3 million related to acquisition initiatives in 2008. Included in other income, net for the year ended December 31, 2007 was $30,000 of costs related to acquisition initiatives. Net interest expense was $17,000 and $0.3 million for the years ended December 31, 2008 and 2007, respectively. The decrease in net interest expense was primarily the result of lower average long-term debt balances during 2008 compared to 2007. Other income, net, also included foreign exchange gains of $0.1 million and $45,000 for the years ended December 31, 2008 and 2007, respectively. These exchange gains were primarily the result of currency fluctuations on intercompany transactions between our subsidiaries.

Income taxes.

Income tax expense from continuing operations was approximately $2.2 million and $2.0 million for the years ended December 31, 2008 and 2007, respectively. The effective income tax rate for continuing operations was 29.3% for the year ended December 31, 2008, compared with 20.6% for the same period of 2007. The difference between our effective tax rate and the US statutory tax rate is principally attributable to foreign tax rate differential and changes in our valuation allowance.

Restructuring

During the quarter ended March 31, 2008, the management of Harvard Bioscience committed to an ongoing initiative to consolidate business functions to reduce operating expenses. Our recent actions have been related to the separation of our electrophoresis product lines from our spectrophotometer and plate reader product lines. As part of these initiatives, we have made changes in management, completed the consolidation of the Hoefer electrophoresis administrative and marketing operations from San Francisco, California to the headquarters of the Harvard Apparatus subsidiary in Holliston, Massachusetts and consolidated the activities of our Asys Hitech subsidiary in Austria to the Company's Biochrom subsidiary's facility located in Cambridge, UK.

During the year ended December 31, 2008, we recorded restructuring charges of approximately $1.8 million. These charges were comprised of $1.0 million in severance payments, $0.3 million in inventory impairment charges related to the discontinuance of certain product lines (included in cost of product revenues), $0.1 million in facility closure costs and $0.4 million in various other costs.

Discontinued Operations

In July 2005, we announced plans to divest our Capital Equipment Business segment. The decision to divest this business based on the fact that market conditions for the Capital Equipment Business were such that this business had not met our expectations and the decision to focus Company resources on the Apparatus and Instrumentation Business segment. As a result, we began reporting the Capital Equipment Business segment as a discontinued operation in the third quarter of 2005.

In November 2007, we completed the sale of the assets of our Genomic Solutions Division and the stock of our Belgian subsidiary, MAIA Scientific, both of which were part of our Capital Equipment Business Segment, to Digilab, Inc. The purchase price paid by Digilab under the terms of the Asset Purchase Agreement consisted of $1,000,000 in cash plus additional consideration in the form of an earn-out based on 20% of the revenue generated by the acquired business as it is conducted by Digilab over a three-year period post-transaction. Any earn-out amounts will be evidenced by interest bearing promissory notes due on November 30, 2012. During the fourth quarter of 2007, we recorded a loss on this sale of $3.1 million. There was no value ascribed to the contingent consideration from the earn-out agreement, as realization is uncertain. The COPAS flow cytometry product line held by our Union Biometrica US and German subsidiaries was not included in this sale.

On September 30, 2008, we completed the sale of assets of our Union Biometrica Division including its German subsidiary, Union Biometrica GmbH, representing at that time the remaining portion of our Capital Equipment Business Segment, to UBIO Acquisition Company. The purchase price paid by UBIO Acquisition Company under the terms of the Asset Purchase Agreement consisted of $1 in cash, the assumption of certain liabilities, plus additional consideration in the form of an earn-out based on the revenue generated by the acquired business as it is conducted by UBIO Acquisition Company over a five-year post-transaction period in an amount equal to (i) 5% of the revenue generated up to and including $6,000,000 and (ii) 8% of the revenue generated above $6,000,000 each year. Any earn-out amounts will be evidenced by interest-bearing promissory notes due on September 30, 2013 or at an earlier date based on certain triggering events. During 2008, we recorded a loss on sale of the Union Biometrica business of $3.3 million. There was no value ascribed to the contingent consideration from the earn-out agreement, as realization is uncertain.

The loss from discontinued operations, net of tax, excluding the loss on sale was $0.5 million for the year ended December 31, 2008. The loss from discontinued operations, net of tax for the year ended December 31, 2008 includes the operating results of our former Union Biometrica US and German subsidiaries. The loss from discontinued operations, net of tax, excluding the . . .
