HBIO REPORTS THIRD QUARTER RESULTS

Harvard Bioscience, Inc. (Nasdaq: HBIO), a global developer, manufacturer and marketer of a broad range of scientific instruments and apparatus used for drug discovery research, today reported financial highlights for the third quarter ended September 30, 2005.

During the third quarter, the Company announced plans to divest its Capital Equipment Business segment. As result of the decision, the Company has classified the Capital Equipment Business segment as discontinued operations - held for sale. Prior period financial results have been reclassified to conform with this presentation. Any further financial information or earnings guidance provided in this press release will relate to our continuing business and will include corporate costs, unless otherwise stated.(1)

Our continuing business is a broad range of well-branded, relatively inexpensive life science products that have strong market positions within niche markets. We sell these products primarily through catalogs, web sites and distributors. Through a combination of organic and acquisition growth we have grown these revenues at a five year compound annual growth rate of approximately 20%. It is a very profitable business with adjusted operating margins typically in the mid to high teens.

Revenues from our continuing operations for the three months ended September 30, 2005 were $17.2 million, an increase of 4.1% compared to revenues of $16.5 million for the same period in 2004. Adjusted non-GAAP income from continuing operations was $1.6 million, or $0.05 per diluted share, for the three months ended September 30, 2005 compared to $1.5 million, or $0.05 per diluted share, for the same period in 2004. Income from continuing operations, as measured under U.S. generally accepted accounting principles ("GAAP"), was $2.1 million, or $0.07 per diluted share, for the three months ended September 30, 2005 compared to $1.3 million, or $0.04 per diluted share, for the same period in 2004.

Revenues from our continuing operations for the nine months ended September 30, 2005 were $49.6 million, an increase of 4.8% compared to revenues of $47.3 million for the same period in 2004. Adjusted non-GAAP income from continuing operations was $4.2 million, or $0.14 per diluted share, for the nine months ended September 30, 2005 compared to $4.5 million, or $0.15 per diluted share, for same period in 2004. Income from continuing operations, as measured under GAAP, was $0.8 million, or $0.02 per diluted share, for the nine months ended September 30, 2005 compared to $3.5 million, or $0.11 per diluted share, for same period in 2004. Included in the GAAP income from continuing operations for the nine months ended September 30, 2005, was a net valuation allowance of $3.5 million on certain deferred tax assets which was recorded during the second quarter of 2005.

"We are pleased with the growth in revenues, gross margin, and adjusted operating profits we reported during the quarter. The increase in demand for our core physiology products such as pumps and respiration equipment, particularly in Europe, has been a major contributor to our success. Additionally, our spectrophotometer product lines have shown double digit growth for the second quarter in a row", said Chane Graziano, CEO of Harvard Bioscience.

Mr. Graziano continued, "We are beginning to see the benefits of the investments we made in marketing during the fourth quarter of 2004 to improve our website, strengthen our direct marketing and expand our international distribution channels."

"Based on the trends we have seen emerging in our core business during the first three quarters of 2005, we are increasing our fourth quarter adjusted earnings per diluted share guidance, which includes corporate costs and excludes amortization of intangible assets, upward from $0.04 to a range of $0.05 - $0.06 and are confirming our original revenue guidance which ranges from $17.0 million to $18.0 million."

Operating Results for Continuing Operations

Three months ended September 30, 2005 compared to three months ended September 30, 2004:

Revenues increased $0.7 million, or 4.1%, to $17.2 million for the three months ended September 30, 2005 compared to $16.5 million for the same period in 2004. Revenues increased in the Harvard Apparatus business approximately $0.4 million across various product lines and approximately $0.5 million in the Biochrom business. Offsetting the increase in revenues for the third quarter of 2005 was a negative foreign exchange impact on sales denominated in foreign currencies of approximately $0.2 million, or 1%.

Cost of product revenues were $8.7 million for the three months ended September 30, 2005 and 2004, respectively. Gross profit as a percentage of revenues increased to 49.5% for the three months ended September 30, 2005 compared with 47.3% for the same period in 2004. The increase in gross margin percentage was mainly due to increased sales volumes, varying product mix and a decrease in certain fixed costs.

Sales and marketing expenses increased $0.1 million, or 6.6%, to $1.9 million for the three months ended September 30, 2005 from $1.8 million for the three months ended September 30, 2004.

General and administrative expenses for the third quarter of 2005 increased $0.5 million, or 17.4%, to $3.2 million compared to $2.7 million for the three months ended September 30, 2004. The increase in general and administrative expense is primarily due to increased costs associated with Sarbanes-Oxley compliance.

Research and development expenses decreased $0.1 million, or 13.9%, to $0.7 million for the third quarter ended September 30, 2005, compared to $0.8 million in the same period of 2004.

Nine months ended September 30, 2005 compared to nine months ended September 30, 2004:

Revenues increased $2.3 million, or 4.8%, to $49.6 million for the nine months ended September 30, 2005 compared to $47.3 million for the same period in 2004. The increase in revenues of approximately $2.3 million was primarily due to sales at Biochrom which grew by approximately $1.1 million and the incremental impact of our 2004 acquisition of KD Scientific of $1.0 million. Also contributing to the increase in revenues for the nine months ended September 30, 2005 was a positive foreign exchange impact on sales denominated in foreign currencies of approximately $0.2 million, or less than 1%.

Cost of product revenues increased $1.0 million, or 4.1%, to $25.4 million for the nine months ended September 30, 2005 compared to $24.4 million for the same period in 2004. The increase in cost of product revenues is directly attributed to the increase in revenues described above. Gross profit as a percentage of revenue increased to 48.7% for the nine months ended September 30, 2005 compared with 48.3% for the same period in 2004.

Sales and marketing expenses increased $0.6 million, or 9.4%, to $6.0 million for the nine months ended September 30, 2005 from $5.4 million for the nine months ended September 30, 2004. The increase in sales and marketing expenses is primarily due to increased investment in direct marketing at our Harvard Apparatus business and expanding distribution channels at our Biochrom business.

General and administrative expenses, including restructuring costs, increased $1.5 million, or 19.3%, to $9.3 million for the nine months ended September 30, 2005 compared to $7.8 million for the nine months ended September 30, 2004. The increase in general and administrative expense is primarily due to costs associated with Sarbanes-Oxley compliance, our acquisition of KD Scientific and $0.3 million of restructuring expenses for the realignment of personnel at our Biochrom, Scie-Plas and Hoefer subsidiaries.

Research and development expenses increased $0.2 million, or 6.8%, to $2.3 million for the nine months ended September 30, 2005 compared to $2.1 million for the nine months ended September 30, 2004.

Balance Sheet

The Company ended the quarter with cash and cash equivalents of $11.3 million, a decrease of approximately $2.6 million since December 31, 2004. The Company ended the third quarter of 2005 with approximately $14.5 million compared to $16.5 million at December 2004 drawn against its $20 million credit facility. Total payments made on the revolving credit facility during 2005 were approximately $2.0 million, of which $0.7 million were made during the third quarter.

Accounts receivable were $10.0 million and inventory was $9.7 million as of September 30, 2005. Outstanding days of sales in the third quarter were 54 days for the three months ended September 30, 2005 compared to 53 days for the same period of 2004. Inventory turns were 3.5 times at September 30, 2005 and 2004, respectively. Both of the comparative periods exclude the Capital Equipment Business which is classified as discontinued operations.

Use of Non-GAAP Financial Information

In this press release, we have included non-GAAP financial information including adjusted statements of income, adjusted income from continuing operations and adjusted earnings per diluted share. 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 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(2) and stock compensation expense, all net of tax. This non-GAAP financial information approximates information used by our management to internally evaluate the operating results of the Company. In particular, we believe that the presentation of a non-GAAP adjusted consolidated statement of income, including a number of adjusted line items, provides investors with a clearer understanding of the full effect of the adjustments that we make to our GAAP net income in order to derive our non-GAAP adjusted net income and net income per share. Tabular reconciliations of our non-GAAP net income (loss) for the three and nine months ended September 30, 2005 and 2004 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.
