EXHIBIT 99.1 FOR IMMEDIATE RELEASE Contact: Fred Pilon, Investor Relations StockerYale, Inc. 603-870-8229 fpilon@stkr.com STOCKERYALE RECEIVES CONTRACT FOR THE DEVELOPMENT OF CUSTOM SPECIALTY OPTICAL FIBER Company Also Announces Installation of MCVD Equipment, And Completion of Equity Private Placement SALEM, N.H., JUNE 4, 2000: StockerYale, Inc. (Nasdaq: STKR), a leading provider of phase masks, specialty optical fiber, and specialized illumination products, today announced that it has received its first contract to develop a custom specialty optical fiber from one of the top-three optical equipment suppliers in the world. Dr. Danny Wong, president of iSOFC, a majority owned subsidiary of StockerYale, will head the research and development team assigned to design this custom specialty optical fiber. It is expected that the research and engineering efforts will be completed by the end of September 2001, and that the production of this specialty optical fiber is projected to begin in the fourth quarter. "One of the key advantages that StockerYale possesses is its ability to focus a portion of its R&D resources on custom optical fiber applications," said Alain Beauregard, StockerYale's president & chief technology officer. "This competence positions StockerYale as an independent developer and manufacturer of high-quality custom and specialty optical fiber, differentiating us from many of our competitors," added Beauregard. MORE NEWS SPECIALTY OPTICAL FIBER (SOF) MANUFACTURING FACILITY OPERATIONAL StockerYale announces that Phase I of the company's SOF facility has been completed with the installation of state-of-the-art modified chemical vapor deposition (MCVD) equipment. This facility will be used for both the production and drawing of specialty fiber optic preforms which in turn, produce specialty optical fiber. The company expects additional MCVD and drawing equipment to become fully operational during the second half of 2001. "With the completion of this facility and Phase I now behind us, we will immediately begin the task of producing the preforms that will be used to manufacture our recently announced specialty optical fiber, as well as other custom-designed specialty optical fibers," said Paul Jortberg, senior vice president of Optical Components. "I believe we are right on target with our commitments for specialty optical fiber and it is likely that first customer shipments will begin by the end of June 2001," continued Jortberg. EQUITY PRIVATE PLACEMENT StockerYale has completed an equity private placement of 1.7 million shares of common stock at a price of $10.25 per share with net proceeds totaling approximately $16 million. In connection with the sale, the company has agreed to provide customary registration rights to the purchasers who were predominantly institutional investors. William Blair & Company acted as exclusive placement agent for the offering. "To secure our place in the fast-moving optical components market, we are continuing to invest heavily in the development of our optical sub-components business by expanding our R&D and manufacturing facilities," said Mark W. Blodgett, StockerYale's chairman & chief executive officer. "More specifically, these proceeds are being targeted at Phase II of our SOF facility, the completion of our new preform production and fiber drawing facility, and the further development of a tunable optical filter prototype which the company expects to demonstrate at the European Conference on Optical Communications, (ECOC), in Amsterdam, Netherlands on October 1-3, 2001. Because of our continued efforts and focus in these areas of development, we can look forward to new optical component product announcements in the next three to six months," Blodgett added. Blodgett continued, "Looking ahead, we expect our optical sub-components business to show strong growth throughout the remainder of the year with sales of our illumination products improving after experiencing some weakness because of a slowdown in the semiconductor, electronic assembly, and disk drive markets."
