Non-GAAP adjusted income from continuing operations was $2.0 million, or $0.07 per diluted share, for the three months ended June 30, 2006 compared to $1.2 million, or $0.04 per diluted share, for the same period in 2005. See Exhibits 4, 5 and 6 for reconciliations of GAAP to non-GAAP adjusted income from continuing operations, GAAP earnings per diluted share to non-GAAP adjusted earnings per diluted share and changes in revenues excluding foreign exchange fluctuations.

Income from continuing operations, as measured under U.S. generally accepted accounting principles ("GAAP"), was $3.4 million, or $0.11 per diluted share, for the six months ended June 30, 2006 compared to $1.8 million, or $0.06 per diluted share, for the same period in 2005. Non-GAAP adjusted income from continuing operations was $4.0 million, or $0.13 per diluted share, for the six months ended June 30, 2006 compared to $2.4 million, or $0.08 per diluted share, for the same period in 2005. See Exhibits 4, 5 and 6 for reconciliations of GAAP to non-GAAP adjusted income from continuing operations, GAAP earnings per diluted share to non-GAAP adjusted earnings per diluted share and changes in revenues excluding foreign exchange fluctuations.

"The second quarter of 2006 was a record quarter in orders, revenues, and non-GAAP adjusted operating income from continuing operations for Harvard Bioscience. Continued strong market demand for our core products was a major contributor to our results. Infusion pumps and amino acid analyzers were particularly strong this quarter," said Chane Graziano, CEO of Harvard Bioscience.

    Highlights for the Three Months Ended June 30, 2006

    --  11.2% organic revenue growth (11.7% overall revenue growth);
    --  39.7% increase in non-GAAP adjusted operating income (51.2%
        increase in GAAP operating income) compared to the same period
        in 2005;
    --  17.2% non-GAAP adjusted operating income as a percent of
        revenue (12.6% GAAP operating income as a percent of revenue,
        including the effect of adoption of SFAS 123R); and
    --  $0.07 non-GAAP adjusted earnings per diluted share from
        continuing operations ($0.06 GAAP earnings per diluted

See Exhibits 3, 5, and 6 for reconciliations of GAAP to non-GAAP adjusted operating income, GAAP earnings per diluted share to non-GAAP adjusted earnings per diluted share and changes in revenues excluding foreign exchange fluctuations.

Mr. Graziano continued, "As we look forward to the third quarter of 2006, we expect to generate revenue between $18.0 and $19.0 million and report non-GAAP adjusted earnings per diluted share from continuing operations between $0.06 and $0.07. In addition, in view of the strong market demand and the acquisition of the Anthos product line, we are increasing our revenue guidance for the full year 2006, from between $70.0 and $72.0 million to revenue between $72.0 and $73.0 million. In addition, we are increasing our guidance for non-GAAP adjusted earnings per diluted share from continuing operations from $0.23 to a range of $0.24 to $0.25."

Operating Results for Continuing Operations

Three months ended June 30, 2006 compared to three months ended June 30, 2005:

Revenues increased $1.9 million, or 11.7%, to $18.2 million for the three months ended June 30, 2006 compared to $16.3 million for the same period in 2005. Excluding the impact of foreign exchange, revenues increased $1.8 million, or 11.2%. The revenue increase was across various product lines, and was primarily attributed to an increase in demand for our pre-clinical testing products and amino acid analyzers. The foreign exchange impact on sales denominated in foreign currencies was $0.1 million during the second quarter of 2006.

Cost of product revenues increased $0.6 million, or 8.0%, to $8.9 million for the three months ended June 30, 2006 from $8.3 million for the three months ended June 30, 2005. Gross profit as a percentage of revenues increased to 50.8% for the three months ended June 30, 2006 compared with 49.1% for the same period in 2005. The increase in gross profit as a percentage of revenues was mainly due to increased sales volumes, improved product mix, and higher margins on certain new product introductions.

Sales and marketing expenses increased $0.4 million, or 15.4%, to $2.4 million for the three months ended June 30, 2006 compared to $2.0 million for the three months ended June 30, 2005. This increase is primarily due to investments in direct marketing initiatives we began during the second half of 2005.

General and administrative expenses were $3.4 million, an increase of $0.1 million, or 2.7%, for the three months ended June 30, 2006 compared to $3.3 million for the three months ended June 30, 2005. The increase in general and administrative expenses is primarily due to approximately $0.4 million, or $0.01 per diluted share, of stock compensation expense recognized upon the adoption of SFAS 123R. Offsetting this increase were restructuring charges of approximately $0.3 million recorded during the second quarter of 2005.

Research and development expenses were $0.8 million and $0.7 million for the three months ended June 30, 2006 and 2005, respectively.

Six months ended June 30, 2006 compared to six months ended June 30, 2005:

Revenues increased $3.2 million, or 9.7%, to $35.6 million for the six months ended June 30, 2006 compared to $32.4 million for the same period in 2005. Excluding the impact of foreign exchange, revenues increased $3.7 million, or 11.5%. The revenue increase was across various product lines, and was primarily attributed to an increase in demand for our pre-clinical testing products, new spectrophotometer products, and amino acid analyzers. Offsetting the increase in revenues during the six months ended June 30, 2006 was a negative foreign exchange impact on sales denominated in foreign currencies of approximately $0.6 million, or 1.8%.

Cost of product revenues increased $0.6 million, or 4.0%, to $17.4 million for the six months ended June 30, 2006 from $16.8 million for the six months ended June 30, 2005. Gross profit as a percentage of revenues increased to 51.0% for the six months ended June 30, 2006 compared with 48.3% for the same period in 2005. The increase in gross profit as a percentage of revenues was mainly due to increased sales volumes, improved product mix, higher margins on certain new product introductions and a decrease in certain fixed costs.

Sales and marketing expenses increased $0.5 million, or 13.4%, to $4.6 million for the six months ended June 30, 2006 compared to $4.1 million for the six months ended June 30, 2005. This increase is primarily due to investments in direct marketing initiatives we began during the second half of 2005.

General and administrative expenses were $6.6 million, an increase of $0.5 million, or 8.0%, for the six months ended June 30, 2006 compared to $6.1 million for the six months ended June 30, 2005. The increase in general and administrative expenses is primarily due to approximately $0.8 million, or $0.02 per diluted share, of stock compensation expense recognized upon the adoption of SFAS 123R. Offsetting this increase were restructuring charges of approximately $0.3 million recorded during the second quarter of 2005.

Research and development expenses were $1.5 million and $1.6 million for the six months ended June 30, 2006 and 2005, respectively.

Balance Sheet

We ended the second quarter of 2006 with cash and cash equivalents of $9.8 million, of which $8.2 million was held in continuing operations and $1.6 million was held in discontinued operations, compared to cash and cash equivalents of $9.8 million at December 31, 2005. During the second quarter, we repaid $2.0 million on our revolving credit facility bringing down the amount outstanding as of June 30, 2006 to $6.5 million compared to $8.5 million at December 31, 2005. The $6.5 million outstanding on our revolving credit facility is reflected as a current liability as of June 30, 2006, because the revolving credit facility is scheduled to expire by its terms on January 1, 2007. The Company intends to enter into a new revolving credit facility prior to the expiration of the existing credit facility.

Accounts receivable were $11.1 million and inventories were $10.6 million as of June 30, 2006. Outstanding days of sales were 57 days for the three months ended June 30, 2006 compared to 51 days for the same period of 2005. Inventory turns were 3.6 times at June 30, 2006 compared to 3.3 times at June 30, 2005.

Discontinued Operations

During the quarter ended September 30, 2005, the Company announced plans to divest its Capital Equipment Business segment. The decision to divest this business segment was based on the fact that market conditions for the Capital Equipment Business have been such that this business has not met the Company's 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. The loss from discontinued operations, net of tax was approximately $2.1 million for the three months ended June 30, 2006 compared to a loss of $24.7 million for the same period in 2005. The loss from discontinued operations, net of tax was approximately $3.2 million for six months ended June 30, 2006 compared to a loss of $25.4 million for the same period in 2005.

Adoption of SFAS 123R

On January 1, 2006, the Company adopted SFAS 123R which requires the measurement and recognition of 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"). The Company adopted SFAS 123R using the modified prospective transition method, which requires the application of the accounting standard as of January 1, 2006, the first day of the Company's fiscal year 2006. In accordance with the modified prospective transition method, the Company's Consolidated Financial Statements for prior periods have not been restated to reflect, and do not include, the impact of SFAS 123R. Stock-based compensation expense recognized under SFAS 123R for the three and six months ended June 30, 2006 was $0.4 million and $0.8 million, respectively, which consisted of stock-based compensation expense related to employee stock options and the employee stock purchase plan, as applicable, and was recorded as a component of cost of sales, sales and marketing expenses, general and administrative expenses, and research and development expenses.

Use of Non-GAAP Financial Information

In this press release, we have included non-GAAP financial information including adjusted operating income, adjusted income from continuing operations, adjusted earnings per diluted share from continuing operations, organic growth and revenue growth excluding foreign exchange. We believe that this non-GAAP financial information provides investors with an enhanced understanding of the underlying operations of the business. For the periods presented, these non-GAAP financial measures of income have excluded certain expenses primarily resulting from purchase accounting or events that we do not believe are related to the underlying operations of the business including amortization of intangibles related to acquisitions, fair value adjustments of inventory and backlog related to acquisitions, restructuring expenses, discontinued operations and stock compensation expense, all net of tax. They also exclude the tax benefits of filing consolidated tax returns for continuing and discontinued businesses and the impact of our cash repatriation program. We believe that organic growth and revenue excluding foreign exchange provide useful information to investors by enabling them to evaluate growth in the parts of our business that we owned throughout all the periods involved, excluding the impact of change in foreign exchange rates. This non-GAAP financial information approximates information used by our management to internally evaluate the operating results of the Company. Tabular reconciliations of our non-GAAP adjusted operating income, non-GAAP adjusted income and earnings per diluted share from continuing operations for the three and six months ended June 30, 2006 and 2005, and our organic growth and revenue growth excluding the impact of foreign exchange for the quarters ending March 31, 2005 through June 30, 2006 compared to the corresponding periods ending from the prior year to the comparable GAAP financial information is included below in this press release.

The non-GAAP financial information provided in this press release should be considered in addition to, not as a substitute for, the financial information provided and presented in accordance with GAAP.
