Sykesville, MD – March 19, 2015 - GSE Systems, Inc. ("GSE" or "the Company") (NYSE MKT: GVP), a global energy industry performance improvement company, today announced financial results for the fourth quarter ("Q4") and year ended December 31, 2014.   Results for Q4 2014 and full year 2014 include the results of Hyperspring, LLC ("Hyperspring") from the date of its acquisition on November 14, 2014.

With the acquisition of Hyperspring, the Company has commenced reporting selected financial results for two business segments: Staff Augmentation, which provides personnel to fulfill staff positions on a short-term basis to energy industry customers; and Performance Improvement Solutions, which provides simulation, engineering and training solutions and services to the nuclear and fossil fuel power industry and to the chemical and petrochemical industries.  Hyperspring's results are included in the Staff Augmentation segment.

Jim Eberle, Chief Executive Officer of GSE, said, "In Q4 2014, we made significant strides in positioning GSE for the future with our acquisition of Hyperspring, our investment in IntelliQlik, LLC, and the restructuring of our U.S. and Swedish operations.  Hyperspring's staff augmentation business contributed $2.3 million to our consolidated Q4 revenue and in 2015 we will be focusing on expanding Hyperspring's U.S. nuclear customer base and diversifying into the fossil power industry.  IntelliQlik continues its development of a next generation, cloud-based software platform for online learning and learning management for all energy sectors and remains on target for a launch in late 2015.  We have restructured our Swedish operations due to a reduced level of simulation business in Japan post-Fukushima and in Europe with the continent's overall economic slowdown.  In 2015 our Performance Improvement Solutions business will be investing in additional business development and operations personnel for solutions aimed specifically at the chemical and petrochemical industries.   Our balance sheet remains strong, with approximately $13.6 million of cash and equivalents at quarter-end and no long-term debt, providing us with flexibility to selectively pursue additional growth opportunities as they arise."

Q4 2014 revenue increased 6.9% to $13.1 million from $12.3 million in Q4 2013, driven by $2.3 million of incremental Staff Augmentation revenue for services provided by Hyperspring, which more than offsets a $1.4 million decline in Performance Improvement Solutions revenue.  The decline in Performance Improvement Solutions revenue primarily was attributable to a $2.5 million decrease in revenue from the $36.6 million Slovakia simulator project, which was completed and entered warranty in April 2014.  Revenue generated from domestic fossil fuel simulation projects increased by $1.4 million in Q4 2014 as compared to Q4 2013 mainly due to a large contract received from a U.S. utility for new high-fidelity operator training simulators for four power plants.

Gross profit in Q4 2014 increased to $4.1 million, or 30.9% of revenue, from $3.6 million, or 29.5% of revenue, in Q4 2013.  Staff Augmentation gross profit was $0.2 million, or 9.8% of Staff Augmentation revenue, in Q4 2014.  Performance Improvement Solutions gross profit was $3.9 million, or 35.3% of Performance Improvement Solutions revenue, in Q4 2014.  The increase in Performance Improvement Solutions gross profit as compared to 4Q 2013 is mainly attributable to an increase in the Company's Swedish gross profit due to the restructuring activities that occurred earlier in 2014 and an increase in EnVision^TM product gross profit offset by a reduction in nuclear simulation gross profit due to the completion of the Slovakia project in April 2014.

Selling, general & administrative expenses in Q4 2014 rose 21.2% to $4.7 million from $3.9 million in Q4 2013. This increase was primarily due to higher software product development expenses ($0.5 million), severance costs related to our U.S. operations ($0.4 million) and Hyperspring acquisition expenses ($0.1 million).

Operating loss for Q4 2014 was $0.9 million compared to an operating loss of $0.5 million in Q4 2013.  Excluding the severance and acquisition expenses, Q4 2014 operating loss was $0.4 million.

Net loss for Q4 2014 was $0.8 million, or $0.05 per basic and diluted share, compared to a net loss of $0.2 million, or $0.01 per basic and diluted share, in Q4 2013.

The EBITDA (Earnings before interest, taxes, depreciation and amortization) loss for Q4 2014 was $0.7 million compared to EBITDA of $0.2 million in Q4 2013.

Backlog at December 31, 2014 rose to $48.4 million from $45.7 million at September 30, 2014, and included approximately $6.7 million of Hyperspring backlog.

GSE's cash position at December 31, 2014 was $13.6 million, excluding $4.2 million of restricted cash, as compared to $16.0 million, excluding $4.2 million of restricted cash, at September 30, 2014.  The decline in cash at December 31, 2014 from September 30, 2014 primarily reflects the $3.0 million payment made by the Company to purchase Hyperspring in Q4 2014.

Management will host a conference call today at 4:30 pm Eastern Time to discuss Q4 results and other matters.

EBITDA Reconciliation

EBITDA is not a measure of financial performance under generally accepted accounting principles ("GAAP").  Management believes EBITDA, in addition to operating profit, net income and other GAAP measures, is useful to investors to evaluate the Company's results because it excludes certain items that are not directly related to the Company's core operating performance. Investors should recognize that EBITDA might not be comparable to similarly-titled measures of other companies.  This measure should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP.  A reconciliation of EBITDA to the most directly comparable GAAP measure in accordance with SEC Regulation G follows:
