HBIO Reports Second Quarter Results and Update on Divestment of Capital Equipment Business Segment

HOLLISTON, Mass., Aug 08, 2005 (BUSINESS WIRE) -- Harvard Bioscience, Inc. (Nasdaq: HBIO), today reported financial highlights for the three and six months ended June 30, 2005 and provided an update on the divestment of the Capital Equipment Business Segment.

Revenues for the three months ended June 30, 2005 were $21.7 million, a decrease of 3% from revenues of $22.5 million for the three months ended June 30, 2004. Net loss, as measured under U.S. generally accepted accounting principles ("GAAP"), for the quarter ended June 30, 2005 was $27.4 million, or $0.90 per basic and diluted share, compared to net income of $0.3 million, or $0.01 per basic and diluted share, for the quarter ended June 30, 2004.

Revenues for the six months ended June 30, 2005 were $44.2 million, a decrease of 1% from revenues of $44.6 million for the six months ended June 30, 2004. Net loss, as measured under GAAP, for the six months ended June 30, 2005 was $27.2 million, or $0.89 per basic and diluted share, compared to net income of $0.2 million, or $0.01 per basic and diluted share, for the six months ended June 30, 2004.

Reflected in the net losses as measured under GAAP for the three and six months ended June 30, 2005, are $17.9 million of non-cash charges for the impairment of goodwill and other intangible assets and $4.2 million of restructuring charges in the Company's Capital Equipment Business Segment. Additionally, a net valuation allowance of $3.5 million on certain deferred tax assets was recorded during the second quarter of 2005.

Quarterly and year-to-date comparisons of revenues by business segment are as follows:

"As previously announced we intend to divest our Capital Equipment business," said Chane Graziano, CEO of Harvard Bioscience. He continued, "We have recently engaged Thomas Weisel Partners, an investment bank, to assist in this process. Therefore, in this quarter's earnings release and conference call we will focus our attention on the continuing Apparatus and Instrumentation business to give our investors a better understanding of its historical performance as well as guidance for the balance of the year.

The Apparatus and Instrumentation business is made up of a broad array of products which generally occupy strong market positions in relatively small markets within the life science industry. These products generally cost less than $10,000 and are usually not classified as capital equipment. We sell these products through our catalog, websites, and distributors such as GE, Fisher and VWR. In this respect the Apparatus and Instrumentation business is more similar to reagent or consumable businesses than capital equipment businesses. We are not dependent on one technology or product line. Although we distribute complementary products made by other companies for the convenience of our customers, approximately 90% of our revenues from this business come from our manufactured products. Because of our broad range of products, and relatively low unit price, revenues for this business are generally more predictable than those for capital equipment. Some of our major product lines are syringe pumps, ventilators, electroporation systems, tissue and organ systems, electrophoresis equipment, spectrophotometers and plate readers.

Our Apparatus and Instrumentation business has been very successful over a long period of time. It has shown good growth and great profitability. We have built this business through a combination of organic and acquisition growth. The Apparatus and Instrumentation business has shown organic growth averaging 10% a year from 1997 to 2004(1). Since 1996, we have made 15 acquisitions into the Apparatus and Instrumentation business. This combination of organic growth plus acquisitions has given this business a five year compound annual growth rate of 20% in revenues, 60% in operating income and 24% in adjusted operating income. Please note that we do not allocate corporate costs to our business segments. Since 2000, adjusted operating margin for this business has consistently been above 20% of revenues. Going forward our goal is to continue this trend.

Organic growth has been driven by expanding distribution channels, utilizing our database of over 150,000 end user scientists and the introduction of new products. Since we expect acquisitions to continue to be an important part of our growth strategy we have recently engaged an investment bank to assist us in identifying a much larger pipeline of potential acquisitions."

The financial history of the Apparatus and Instrumentation
business is summarized below:

Please refer to Exhibit #6 for a reconciliation of GAAP operating income to Non-GAAP operating income by business segment.

Prior to 2000 all corporate costs are included in the above results. From 2000 onward we did not allocate corporate costs to either the Apparatus and Instrumentation business or the Capital Equipment business.

Second quarter results for the Apparatus and Instrumentation business were strong with orders growth of 8% over both Q1 this year and Q2 last year. Revenues grew 4% with the favorable effect of foreign exchange less than 1%. Adjusted operating margin was again over 20% of revenues.

Guidance for the balance of 2005, which excludes the Capital Equipment business and which we intend to account for under held for sale accounting beginning in the third quarter of 2005, is as follows:

2005 By Quarter                      Q3                      Q4
Apparatus & Instrumentation
Revenues                        $16-17 million          $17-18 million
Non-GAAP Adjusted Diluted EPS   $ 0.07                  $ 0.07

Corporate costs EPS            ($ 0.03)(a)             ($ 0.03)(a)
Non-GAAP net diluted EPS        $ 0.04                  $ 0.04

(a) Note that until the Capital Equipment business is divested
Harvard Bioscience will continue to bear corporate costs for both
segments and therefore we will continue to report Apparatus and
Instrumentation business results and Corporate costs separately until
the Capital Equipment business is divested. Once the Capital Equipment
business is divested we expect Corporate costs to decrease by an
annualized $0.02-$0.03 per share from 2005 levels.

Non-GAAP adjusted diluted earnings per share exclude the amortization of intangible assets of approximately $0.4 million per quarter and assume an estimated effective tax rate of 40%.

Update on Divestment of the Capital Equipment Business.

On July 27th we announced our intention to divest the Capital Equipment business. This process is moving forward as planned. We expect to use the proceeds to pay down our $15.2 million debt facility and to fund our growth strategy of tuckunder acquisitions.

Operating Results for Continuing Operations - Apparatus and Instrumentation and Corporate

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

Apparatus and Instrumentation revenues increased $0.7 million, or 4.2%, to $16.3 million for the three months ended June 30, 2005 from $15.6 million for the three months ended June 30, 2004. The increase in sales at Harvard Apparatus of approximately $0.2 million was primarily due to the increase in sales across various domestic product lines. Revenues increased approximately $0.4 million at our Biochrom subsidiary primarily due to the establishment of additional European distribution channels, increased sales to G.E. Healthcare, and an increase in sales at our Asys subsidiary. Also contributing to the increase in revenues for the second quarter of 2005 was a positive impact on sales denominated in foreign currencies of approximately $0.1 million.

Apparatus and Instrumentation cost of product revenues increased $0.3 million, or 4.2%, to $8.3 million for the three months ended June 30, 2005 from $8.0 million for the three months ended June 30, 2004. The increase in cost of product revenue is directly attributed to the increase in revenues described above.

Apparatus and Instrumentation sales and marketing expenses increased $0.2 million, or 11.0%, to $2.0 million for the three months ended June 30, 2005 from $1.8 million for the three months ended June 30, 2004. The increase in sales and marketing expenses of $0.2 million is primarily due to increased investment in direct marketing at Harvard Apparatus.

Apparatus and Instrumentation general and administrative expenses increased $0.1 million, or 6.9%, to $1.7 million for the three months ended June 30, 2005 from $1.6 million for the three months ended June 30, 2004. The increase in general and administrative expense is primarily due to the increased investment noted above at Harvard Apparatus.

Corporate general and administrative expenses increased $0.3 million, or 29.2%, to $1.3 million for the three months ended June 30, 2005 from $1.0 million for the three months ended June 30, 2004. The increases in general and administrative expenses are primarily due to costs associated with Sarbanes-Oxley compliance.

Apparatus and Instrumentation research and development expenses of $0.7 million for the three months ended June 30, 2005, were relatively consistent with the same period of 2004.

Six months ended June 30, 2005 compared to six months ended June 30, 2004:

Apparatus and Instrumentation revenues increased $1.6 million, or 5.2% to $32.4 million for the six months ended June 30, 2005 from $30.8 million for the six months ended June 30, 2004. The increase in revenues of approximately $1.6 million was primarily due to an increase of approximately $0.7 million in sales of syringe pumps in our recently acquired KD Scientific business and of approximately $0.7 million in our Biochrom reporting unit due to the establishment of additional European distribution channels and an increase in sales at our Asys subsidiary. Also contributing to the increase in revenues for the first six months of 2005 was a positive impact on sales denominated in foreign currencies of approximately $0.3 million.

Apparatus and Instrumentation cost of product revenues increased $1.0 million, or 6.5%, to $16.8 million for the six months ended June 30, 2005 from $15.7 million for the six months ended June 30, 2004. The increase in cost of product sales is directly attributed to the increase in revenues described above and an increase in sales of products with lower gross margins at our Biochrom subsidiary.

Apparatus and Instrumentation sales and marketing expenses increased $0.4 million, or 10.8%, to $4.1 million for the six months ended June 30, 2005 from $3.7 million for the six months ended June 30, 2004. The increase in sales and marketing expenses is primarily due to increased investment in direct marketing at Harvard Apparatus and expanding distribution channels at Hoefer.

Apparatus and Instrumentation general and administrative expenses increased $0.2 million, or 6.2%, to $3.5 million for the six months ended June 30, 2005 from $3.3 million for the six months ended June 30, 2004. The increase in general and administrative expense is primarily due to our acquisition of KD Scientific and to an increase in salary and related expenses.

Corporate general and administrative expenses increased $0.6 million, or 28.8%, to $2.4 million for the six months ended June 30, 2005 from $1.8 million for the six months ended June 30, 2004. The increases in general and administrative expenses are primarily due to costs associated with Sarbanes-Oxley compliance.

Apparatus and Instrumentation research and development expenses increased $0.3 million, or 19.2%, to $1.6 million for the six months ended June 30, 2005 from $1.3 million for the six months ended June 30, 2004. The increase was primarily due to investment to launch our new BTX 2001 electrofusion system.

Balance Sheet

The Company ended the quarter with cash and cash equivalents of $13.2 million, a decrease of approximately $0.7 million since December 31, 2004. The Company ended the quarter with approximately $15.2 million drawn against its $20 million credit facility.

Use of Non-GAAP Financial Information

In this press release, we have included non-GAAP financial information including adjusted statements of income before income taxes for our Apparatus and Instrumentation and Capital Equipment Business Segments, adjusted operating income, adjusted operating margin, 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(4) 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. In this quarter, due to our decision to divest the Capital Equipment Business Segment, we believe that the presentation of non-GAAP adjusted consolidated statements of income on a segment by segment basis is useful to provide investors with a clearer understanding of our business as we intend to operate it following the divestiture. Tabular reconciliations of our non-GAAP income (loss) before taxes for our Apparatus and Instrumentation and Capital Equipment Business Segments for the three and six months ended June 30, 2005 and 2004 and our non-GAAP adjusted operating income for our Company as a whole, our Apparatus and Instrumentation and Capital Equipment Business Segments and our Corporate expenses for the years ended December 31, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 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.

(1)Organic growth includes revenue growth under Harvard Bioscience's ownership. For example, revenues under Harvard Bioscience ownership compared to revenues during the preceding 12 month period under the previous ownership.
