      Explanation:

      Set forth below is preliminary  consolidated  results of operations data
for Acorn Factor,  Inc.  (the  "Company")  for the quarter and six months ended
June 30, 2007 and comparative data for the same periods in 2006.

      The Company had net income of $13.6 and $11.9 million for the quarter and
six months ended June 30, 2007, as compared to a net loss of $0.8 and $3.6
million for the quarter and six months ended June 30, 2006.

      Net income for both the quarter and six months ended June 30, 2007
included a non-cash gain of $16.2 million with respect to the public offering of
Comverge and a non-cash finance expense of $1.1 million ($1.9 million in the
six-months ended June 30, 2007) recorded with respect to the Company's recent
private placement of Debentures.

      Sales in the first six months of 2007 decreased by $243,000, or 12%, from
$2.0 million in the first six months of 2006 to $1.7 million in the first six
months of 2007. Sales in the second quarter of 2007 reflected a decrease of
$309,000, or 31%, from $1.0 million in the first quarter of 2007 to $0.7 million
in the second quarter of 2007. The decreases for both periods were attributable
to decreases in both RT Solutions and OncoProTM segment sales due to reduced
project backlogs, as well as an allocation of resources to adapt our OncoProTM
software product to the US market.

      Gross profit in the first six months of 2007 decreased by $232,000 from
$573,000 to $341,000, compared to the first six months of 2006. The decrease was
primarily attributable to decreased gross profits in the RT Solutions segment
due to both lower sales and lower margins due to the inclusion in 2006 periods
of certain project sales with relatively high gross profit margins. Gross profit
in the second quarter of 2007 decreased by $289,000 from $345,000 to $56,000, in
comparison to the second quarter of 2006, primarily due to the decrease in RT
Solutions sales and margins.

        Selling, marketing, general and administrative expenses ("SMG&A") in the
first six months of 2007 decreased slightly ($107,000) from $2.0 million to $1.9
million compared to the first six months of 2006, and was stable at $1.0 million
for both the second quarters of 2007 and 2006. SMG&A expenses have decreased in
the Company's dsIT subsidiary, however this decrease has been partially offset
by increases in corporate SMG&A expense.


      In April 2007, Comverge completed its initial public offering. As a result
of the Comverge offering, the Company recorded an increase in its investment in
Comverge and recorded a non-cash gain of $16.2 million in "Gain on public
offering of Comverge". Subsequent to the offering, the Company no longer
accounts for its investment in Comverge under the equity method and accounts for
its Comverge investment under the cost method.

      Due to certain restrictions relating to the Comverge shares held by the
Company, not all the Company's 2,786,021 Comverge shares were considered
"available-for-sale" at June 30, 2007 under applicable accounting standards. The
Company's management has determined that at June 30, 2007, approximately 543,000
shares of Comverge's common stock can be considered unrestricted under the
provisions of the applicable accounting standards, and accordingly recorded an
increase in its investment balance and an increase in accumulated other
comprehensive income in the shareholders' equity section of the balance sheet by
$14.0 million with respect to the recording those shares at fair market value.

      The Company expects that at the end of the third quarter of 2007, the
Company's entire investment in Comverge's common stock will be considered
"available-for-sale" under applicable accounting standards and will be reflected
on the Company's balance sheet at its fair market value on September 30, 2007.

      Finance expense, net, increased in the first six months of 2007 as
compared to the first six months of 2006 from $6,000 to $2.1 million. Finance
expense, net, also increased in the second quarter of 2007 as compared to the
second quarter of 2006 from $20,000 to $1.3 million. The increases are entirely
attributable to the finance costs associated with our private placement of
convertible debt in the first and second quarters of 2007.

      In the first six months of 2007, the Company recognized losses of $356,000
representing its approximately 33% share of Paketeria's losses for the period
and amortization expense associated with acquired non-compete and franchise
agreements and the change in value of a put option. In addition, the Company
also recognized additional losses totaling $32,000 with respect to stock
compensation expense associated with an option grant.

      Certain  statements made above are  forward-looking  in nature.  Whether
such  statements  ultimately  prove to be accurate  depends  upon a variety of
factors that may affect the Company's  business and operations.  Many of these
factors are described in the Company's  most recent Annual Report on Form 10-K
as filed with Securities and Exchange Commission.
