GSE Systems, Inc. (“GSE” or “the Company”) (NYSE Amex: GVP), a global energy services solutions provider, today announced that it has entered into a new, two-year, $7.5 million revolving line of credit with Susquehanna Bank. The new credit facility, which replaces a facility scheduled to expire in May 2012, will be used by GSE to issue stand-by letters of credit (LC) and for working capital purposes, subject to specified terms and conditions. The interest rate of the new facility is The Wall Street Journal Prime Rate, floating with a floor of 4.5%. GSE is in the process of transferring LCs in the amount of $4.5 million from its prior credit facility to the Susquehanna facility, which will reduce the availability on the facility on a dollar-for dollar basis. Jim Eberle, Chief Executive Officer of GSE, commented, “We are very pleased to enter into a relationship with Susquehanna Bank. Their support will assist us in pursuing our growth initiatives and enhancing our liquidity.” At September 30, 2011, GSE’s balance sheet reflected $0 long-term debt, $17.7 million of cash and cash equivalents, and $5.0 million of restricted cash related to cash collateralization requirements required under the Company’s prior credit facility. This new facility will, over time and subject to specified terms and conditions, enable GSE to reduce its restricted cash position. Additional details regarding the new facility are available in a Form 8-K, which GSE will file with the Securities and Exchange Commission on or about November 28, 2011. ABOUT GSE SYSTEMS, INC.
