Acorn Factor Acquires SCR-Tech for $9.6 Million
--Establishes CoaLogix™ Platform for Participating in Burgeoning Clean Coal Market
--Further Expands Holdings and Solidifies Leadership in Energy Intelligence Sector

Montchanin, DE (November 8, 2007) – Acorn Factor, Inc. (OTCBB: ACFN), a leader in the high-growth
energy intelligence sector, today announced that it has completed the purchase of SCR-Tech LLC from
Catalytica Energy Systems, Inc., a subsidiary of Renegy Holdings, Inc., for a purchase price of $9.6
million in cash. SCR-Tech is a leading provider of catalyst regeneration technologies and management
services for selective catalytic reduction (SCR) systems used by coal-fired power plants to reduce
nitrogen oxides (NOx) emissions and will operate as part of CoaLogix™, Acorn Factor’s newly
established platform for participating in the burgeoning clean coal market.

Based in Charlotte, North Carolina, SCR-Tech is the only company in North America offering a
commercial process capable of fully restoring catalyst activity and NOx reduction performance. SCRTech
also provides SCR catalyst management and consulting services including computer simulation,
inspection, testing and analysis to help utilities, independent power producers, and other SCR operators
optimize their NOx reduction performance and achieve regulatory compliance at lower costs.

Commenting on the establishment of the CoaLogix platform and the purchase of SCR-Tech, John
A. Moore, CEO of Acorn Factor stated: “We believe that one of the biggest opportunities in the energy
sector today is the improvement of efficiency and reduction of the environmental footprint of the coal
burning plants that currently provide over 50% of the US electricity supply. SCR-Tech is the cornerstone
of CoaLogix, our newly established intelligent clean coal platform, which seeks to bring specialized
resources and talent to this huge but underserved sector of the energy economy. Here, small gains in
efficiency and environmental impact could dwarf those of the other emerging technologies like solar and
wind power. Over the past several years, SCR-Tech has essentially created a new market in the US for
SCR catalyst regeneration. The field has massive growth potential, both organically as well as through
the possible acquisition or licensing of new technologies. ”

“We at SCR-Tech are thrilled to be part of Acorn Factor, with its strong balance sheet, knowledge
of and vision for the future of the energy industry, as reflected in its founding and nurturing of Comverge,
and track record of attracting premier partners and co-investors,” said William McMahon, CEO of
CoaLogix and SCR-Tech. “With the support of our new parent and partner and our existing management,
marketing and technical team we look forward to continuing to provide innovative solutions to support
clean coal generation.”

acquisition, with Eilenberg Krause & Paul LLP serving as legal advisor.
