HAMILTON THORNE ANNOUNCES 2011 FIRST QUARTER FINANCIAL RESULTS

The Company Reports 22% Growth for the Quarter

BEVERLY, MA and TORONTO, Ontario – June 9, 2011 - Hamilton Thorne Ltd. (TSX-V: HTL), a leading provider of advanced laser systems for the regenerative medicine, fertility and stem cell research markets, today reported operational and financial results for the first quarter ended March 31, 2011.
“Hamilton Thorne achieved strong year-over-year growth for the first quarter of 2011, with the Company recording a 22% increase in sales over the same period last year. This growth was primarily driven by robust laser sales, especially in key markets such as cell biology, regenerative medicine and stem cell research,” said Meg Spencer, Chief Executive Officer of Hamilton Thorne Ltd. “Our R & D team continues to innovate on our sleek laser design and increase the efficiency and accuracy of our products, helping our customers unlock the therapeutic potential for treating life-threatening and debilitating diseases.”

Highlights

  • The Stiletto™ Laser System continues to perform well at several prestigious beta sites. The Stiletto successfully automates the process of splitting stem cell colonies into equal sections for easy removal of the sections to a new growing environment and the obliteration of thousands of unwanted cells in seconds to purify samples. Beta testers have shown that the non-contact capability of the laser prevents contamination, minimizes damage to the cells and avoids change in gene expression through multiple generations of colony growth.
  • Hamilton Thorne has also secured distribution or OEM deals for accessory products including the Tokai Hit stage warmers and the 20/20 stage coolers. As temperature control is very important for many cell procedures, these partnerships should provide Hamilton Thorne customers with better options for cell maintenance.
  • In Q1, Hamilton Thorne’s products were referenced in over 14 new peer-reviewed scientific articles by customers at world-leading research labs and academic institutions. Hamilton Thorne’s fertility products and advanced laser systems were published in several prestigious scientific journals such as Methods of Molecular Biology, Human Reproduction and Biology Reproduction.
  • The Company completed an offering of 10% convertible unsecured subordinate debentures (“Debentures”) for aggregate gross proceeds of approximately US $650,000. The net proceeds from the sale of the Debentures will be used for potential product line acquisitions and in-licensing, research and development expenses and for general working capital purposes.

Financial Results

All amounts are in US dollars, unless specified otherwise, and results expressed in accordance with the International Financial Reporting Standards ("IFRS"), which replaces Canadian Generally Accepted Accounting Policies ("GAAP") effective January 1, 2010 for all publicly accountable enterprises in Canada.

For the three months ended March 31, 2011, the Company recorded sales of $1,445,000 compared to $1,181,000 for the same period last year. The Company’s total sales increased 22% for the quarter over the previous year, and was attributable to increased demand for our existing products and improved budget availability for capital equipment purchases across all customer types and geographic regions.

Operating expenses were $1,500,000 for the quarter ended March 31, 2011, up from $1,211,000 during the previous year, an increase of $289,000, or 24%. This increase in operating expenses represents continued strategic investment in the growth of the Company.

Research and development (R&D) expenses increased 20% to $299,000 due to continued development of new products. Sales and marketing expenses increased 31% to $634,000 due to the expansion of our sales force, commission expense on higher sales volume, and increased variable costs of selling.

General and administrative (G&A) expenses increased 19% to $566,000 due primarily to increases in staffing and a foreign currency valuation adjustment related to the convertible debentures issued in August 2010 and March 2011, which were issued in Canadian dollars.

Net interest expense increased to $127,000 for the quarter ended March 31, 2011 from $70,000 for the prior year period. The increase was due to the interest expense, both coupon and accreted, on the Company’s convertible debentures.

The net loss for the quarter ended March 31, 2011 was $746,000, an increase of 31% over the net loss of $571,000 for the same period of the previous year. The increased loss was due primarily to the additional investments by the Company in research, product development, sales and marketing, additional general and administrative expenses, and additional interest expense, partially offset by increased gross profit resulting from increased sales.

As of March 31, 2011, the Company had 24,415,157 common shares, 6,134,441 warrants, 4,432,022 options, and 440,001 agent compensation options outstanding.
