INTRODUCTION & VISION• Gemma Power Systems (GPS) is an

Engineering – Procurement – Construction Company

• GPS has been in business since 1997, Acquired by Argan, Inc. (NSYE: AGX) in 2007

• Focus on combustion turbine-based projects

• Look for opportunities with developers with a track record of closing deals, that value our core values, and with multiple projects in development

• We believe natural gas combined cycle plants will continue to replace coal plants in PJM, but at a slower pace
