IES Renewable Energy, LLC (“IES Renewable”), a residential solar energy
integrator and installer and indirect wholly-owned subsidiary of Integrated
Electrical Services, Inc. (or “IES”) (NASDAQ: IESC), announced that it has
entered into a new partnership with Sunrun, one of the nation’s leading home
solar companies. Through this partnership, IES Renewable will design, engineer

alternative,” said Dwayne Collier, President of IES Renewable and IES

quality service to more homeowners in California,” said Sunrun co-CEO Edward
Fenster. “We remove high costs and hassle to make the switch an easy choice
for more homeowners.”

in such statements. Such risks and uncertainties include, but are not limited
to, fluctuations in operating activity due to downturns in levels of
construction, seasonality and differing regional economic conditions;
competition in our respective industries, both from third parties and former
employees, which could result in the loss of one or more customers or lead to
lower margins on new projects; a general reduction in the demand for our
services; a change in the mix of our customers, contracts and business; our
ability to successfully manage projects; possibility of errors when estimating
revenue and progress to date on percentage-of-completion contracts; inaccurate
estimates used when entering into fixed-priced contracts; challenges
integrating new businesses into the Company or new types of work or new
processes into our divisions; the cost and availability of qualified labor;
accidents resulting from the physical hazards associated with our work and the
potential for accidents; success in transferring, renewing and obtaining
electrical and construction licenses; our ability to pass along increases in
the cost of commodities used in our business, in particular, copper, aluminum,
steel, fuel and certain plastics; potential supply chain disruptions due to
credit or liquidity problems faced by our suppliers; loss of key personnel and
effective transition of new management; warranty losses, damages or other
latent defect claims in excess of our existing reserves and accruals; warranty
losses or other unexpected liabilities stemming from former divisions which we
have sold or closed; growth in latent defect litigation in states where we
provide residential electrical work for home builders not otherwise covered by
insurance; limitations on the availability of sufficient credit or cash flow
to fund our working capital needs; difficulty in fulfilling the covenant terms
of our credit facilities; increased cost of surety bonds affecting margins on
work and the potential for our surety providers to refuse bonding or require
additional collateral at their discretion; increases in bad debt expense and
days sales outstanding due to liquidity problems faced by our customers;
changes in the assumptions made regarding future events used to value our
stock options and performance-based stock awards; the recognition of potential
goodwill, long-lived assets and other investment impairments; uncertainties
inherent in estimating future operating results, including revenues, operating
income or cash flow; disagreements with taxing authorities with regard to tax
positions we have adopted; the recognition of tax benefits related to
uncertain tax positions; complications associated with the incorporation of
new accounting, control and operating procedures; the financial impact of new
or proposed accounting regulations; the ability of our controlling shareholder
to take action not aligned with other shareholders; the possibility that
certain tax benefits of our net operating losses may be restricted or reduced
in a change in ownership; credit and capital market conditions, including
changes in interest rates that affect the cost of construction financing and
mortgages, and the inability for some of our customers to retain sufficient
financing which could lead to project delays or cancellations; the sale or
disposition of the shares of our common stock held by our majority
shareholder, which, under certain circumstances, would trigger change of
control provisions in contracts such as employment agreements and financing
and surety arrangements; and additional closures or sales of facilities could
result in significant future charges and a significant disruption of our
operations. You should understand that the foregoing, as well as other risk
factors discussed in this document and in the Company’s annual report on Form
