Visual Numerics® Moves Headquarters to Houston

35 Year-old Numerical Analysis Leader Returns to Texas Roots
with Plans to Pursue Emerging Business Intelligence Markets

SAN RAMON, Calif. – May 2, 2006 – Visual Numerics, Inc., celebrating 35 years of producing advanced numerical analysis and visualization software, announced that effective today it has moved its headquarters and executive team from San Ramon, California back to Houston, Texas, one of the company’s two principle R&D centers. In Houston, which has the second highest number of Fortune 500 companies after New York City, Visual Numerics will be in a better position to maximize the efficiency of its R&D efforts and take advantage of the favorable cost of living as the company grows its employee base. In the next five years, Visual Numerics will also pursue emerging markets such as business analytics, as well as traditional market segments such as oil and gas and high-performance computing.

Visual Numerics also plans to work more closely with the University of Houston, Rice University and other academic institutions. In 2002, Visual Numerics launched the Knowledge in Motion™ program, an attractive pricing program for professors and students aimed at encouraging exploration of the practical side of mathematics and statistics.

“It is more critical than ever to excite students about math and science,” says Phil Fraher, president and CEO of Visual Numerics. “It’s incumbent on companies like us who have the right mathematics tools and expertise to make them available to this next generation of scientists and quantitative experts.”

Fraher foresees a greater need for sophisticated visual data analysis solutions for the state’s oil market. As a software engineer at Exxon earlier in his career, Fraher worked on the first generation of visualization software for oil exploration, which is similar to what Visual Numerics now sells to worldwide oil companies and other industry companies with large data sets.

“Building proprietary analytics applications to handle massive data sets will not only become a business imperative for companies, but it will be a key competitive differentiator as well,” said Fraher. “I’m excited about returning to Houston because we’re bringing our seasoned executive management and tenured R&D teams closer together to build even better data analysis and visualization software for our customers so they can solve real world business problems. We’re in this for the long haul.”

In 1970 when founder Chuck Johnson launched the company in Houston, then known as International Mathematical and Statistical Libraries (IMSL™), it sold its advanced libraries of mathematical and statistical routines to R&D laboratories and corporate testing facilities. The company moved its headquarters to Silicon Valley, CA in 2001 to be closer to its reseller partners and immerse itself in the Valley’s energetic start-up climate. Now, Visual Numerics’ IMSL Family of Libraries are used by over 500,000 people worldwide for important research from analyzing cancer treatment data to forecasting mobile phone traffic, and hundreds of other critical applications that require math and statistics. The company has nine other offices around the world, and long-term OEM and reseller relationships with global partners such as Intel, IBM and Microsoft.
