NEUTRAL

IIDDAACCOORRPP ((IIDDAA))
1Q10 Results and 2010 Outlook Reaffirmed - Maintaining NEUTRAL Rating
Highlights
• We are maintaining our NEUTRAL rating on IDA shares. Our price target of $35 per
share is based on a 2010/2011/2012 P/E of 12.9x/11.7x/11.4x our EPS estimates of
$2.72/$3.00/$3.08.
• On May 6, 2010, IDA reported 1Q10 financial results. 1Q10 net income totaled $16.1m or
$0.34 per share compared to a net income of $18.9m or $0.40 per share in 1Q09 and our estimate of $0.40 per share. Results were primarily attributable to rate and other regulatory
recovery (+$8.9m), lower income taxes (+$3.0m) and increased ITC amortization (+$4.5m), offset by lower sales volumes due to a weak economy (-$6.7m), decreased life insurance
gains (-$3.3m), lower earnings at Bridger Coal Company (-$3.0m), higher depreciation expense related to AMI (-$2.6m) and payroll increases (-$1.8m). IDA also reaffirmed its
2010 earnings guidance range of $2.65-$2.80 per share. Key drivers of 2010 guidance: O&M expense of approximately $295m-$305m, Capital expenditures of $355m-$365m,
hydroelectric generation of 6.5-8.5m MWh, Non-regulated earnings of $0-$3m, the use of investment tax credits to achieve 9.5% ROE floor.
• Our 2010 EPS estimate of $2.72 assumes Idaho Power can earn at least 9.5% ROE and is
in-line with guidance. Our 2011 EPS estimate of $3.00 assumes Idaho Power can earn at
least 9.5% ROE based on $1.5b of year-end equity balance (supported by $84m of deferred
energy recovery in 2010, modest 2010/2011 DRIP-related and sales agency agreement
equity issuances, retained earnings partially offset by dividends). Our preliminary 2012
EPS estimate of $3.08 assumes IDA will file a rate case in mid-2011 (with forward test year)
for new rates effective January 2012 to recover incremental costs over the 2010-2012 period including inclusion of Langley Gulch in rates.
• Brownlee and Hells Canyon, IDA’s largest hydroelectric generation facility, are forecasted to
have water supplies 51% and 50% of their 30-year averages (as of the April 7, 2010 NOAA official regression forecast for April-September 2010), respectively. IDA’s hydroelectric
facilities are primarily located on the Snake River along the Idaho/Oregon border. In terms of IDA, new rate structure (9.5% ROE floor) and more accurate forward looking hydro
supply methodology (filed in April) helps mitigate earnings/cash volatility. IDA generated 1.9m MWh of hydro capacity in 1Q10 compared with 1.6m MWh in 1Q09 and expects 6.5-
8.5m MWh for all of 2010 compared with 8.1m MWh in 2009.
• According to management, the Board continues review IDA dividend policy and while it
acknowledges the current below average yield of 3.5%, considering its aggressive capital
budget a material dividend increase is not in the near future. In terms of external capital
needs to support its capital budget, IDA believes that minimal financing is needed for the
balance of 2010, a debt refunding in necessary by early 2011 and the company has 2.1m
remaining on its DRIP program. We believe IDA can remain flexible in the near-term.
• Rate base growth and corresponding earnings growth is supported in the near-term by the pre-approved Langley Gulch power pant (COD 2012). Longer-term growth is supported by
the pending Boardman to Hemingway Line (COD 2015) which is needed for reliability and the Gateway West Line (230-500 kV, $500-$600m total cost, COD TBD).

APPENDIX A: IMPORTANT RESEARCH DISCLOSURES

ANALYST CERTIFICATION
I, Brian Russo, attest that the views expressed in this research report accurately reflect my personal views about the subject security
and issuer. Furthermore, no part of my compensation was, is, or will be directly or indirectly related to the specific recommendation or
views expressed in this research report.
The research analyst(s) primarily responsible for the preparation of this research report have received compensation based upon
various factors, including the firm’s total revenues, a portion of which is generated by investment banking activities.

COMPANY BACKGROUND
Headquartered in Boise, Idaho, IDACORP, Inc., (IDA) is a holding company formed in 1998 that is primarily engaged in the
generation, transmission, distribution, sale and purchase of energy. IDA serves over 466,000 retail customers across its 24,000sq
mile service territory in both Idaho and Oregon, and owns approximately 3,267MW of generating capacity. IDA’s principal operating
subsidiary is Idaho Power Company (IPC). The company’s unregulated utilities include IDACORP Financial (IFS) that invests in
affordable housing and real estate and Ida-West Energy Company (Ida-West) that operates small hydroelectric generation projects.
VALUATION METHODOLOGY
We value equities utilizing a multi-faceted approach which includes; sum-of-the-parts, net asset value, discounted cash flow, leading
P/E, EV/EBITDA.
RISKS
On top of normal economic and market risk factors that impact most all equities, Idacorp (IDA) is uniquely at risk to:
Because of IPC’s predominantly hydroelectric generating base and heavy reliance on hydroelectric generation, which can be
adversely affected by weather, reduced hydroelectric generation can reduce revenues and increase costs.
Continuing declines in stream flows and over-appropriation of water in Idaho may reduce hydroelectric generation and revenues and
increase costs.
Load growth in IPC’s service territory due to customer growth and demand for energy exposes it to greater market and operational risk
as increased reliance on purchased power to meet load requirements could increase costs and reduce earnings and cash flows.
IPC’s reliance on coal and natural gas to fuel its generating facilities exposes it to risk of increased market prices, which could
increase costs and reduced earnings.
Changes in temperature and precipitation can reduce power sales and revenues.
Climate change could affect customer demand and hydroelectric generation and lead to restrictions on generation resources.
If Idaho Public Utility Commission (IPUC), the Oregon Public Utility Commission (OPUC) or the Federal Energy Regulatory
Commission (FERC) grant less rate recovery in rate case filings than IPC needs to cover the costs of providing services, financial
results could be adversely impacted and economic expansion may be limited.
Conditions that may be imposed in connection with hydroelectric license renewals may require large capital expenditures and reduce
earnings and cash flows.
The cost of complying with environmental regulations related to air quality, water quality, natural resources and health and safety can
increase capital expenditures and operating costs and reduce earnings and cash flows.
IDACORP and its subsidiaries are subject to costs and other effects of legal and regulatory proceedings, settlements, investigations
and claims, including those that have arisen out of the western energy situation.
IPC’s business is subject to substantial governmental regulation and may be adversely affected by increased costs resulting from, or
liability under, existing or future regulations or requirements.
Increased capital expenditures can significantly affect liquidity.
As a holding company, IDACORP does not have its own operating income and must rely on the upstream cash flows from its
subsidiaries to pay dividends and make debt payments.
A downgrade in IDA’s credit ratings could negatively affect the company’s ability to access capital and increase their cost of
borrowing.
Adverse results of income tax audits could reduce earnings and cash flows.
Employee workforce factors, including the loss or retirement of key personnel, availability of qualified personnel and an aging
workforce, could increase costs and reduce earnings.
