SAN CLEMENTE, CA – August 2, 2006 – Sunstone Hotel Investors, Inc. (the “Company”) (NYSE: SHO) today announced results of operations for the second quarter ended June 30, 2006.

SECOND QUARTER 2006 HIGHLIGHTS

• Adjusted EBITDA of $71.8 million (80.9% increase over second quarter 2005);

Robert A. Alter, Chief Executive Officer, stated “We are extremely pleased with our second quarter results, especially from the Renaissance acquisition we made in 2005. It strengthens our belief that we are in the midst of a broad recovery in the hotel industry. Further, we were very pleased with our California hotels which have produced RevPAR increases of 10.6% for the second quarter and 11.5% year to date. We continued our strategy of acquiring high quality assets in high barrier to entry markets by acquiring the La Jolla Embassy Suites in San Diego and the W San Diego. In addition, we completed the extensive renovation of the Fairmont Newport Beach. Finally, we continue to be encouraged about 2006 as hotel market fundamentals remain strong and our portfolio continues to post outstanding results from operations.”

Performance Relative to Guidance

The following table reflects our guidance for the second quarter 2006 compared to our actual results.

	Guidance	Actual Second Quarter 2006
RevPAR Growth	7.0% to 9.0%	10.0% excluding two hotels under rebranding and renovation programs and 9.2% overall
Adjusted EBITDA	$69.0 million to $72.0 million	$71.8 million
Adjusted FFO available to common stockholders	$43.1 million to $46.1 million	$46.4 million
Adjusted FFO available to common stockholders per diluted share	$0.69 to $0.74	$0.75

Comparable RevPAR for 59 hotels owned for the entire quarter, excluding 2 hotels undergoing rebranding and renovation programs (Fairmont Newport Beach and Hyatt Regency Century Plaza) increased 10.0% as compared to the second quarter of 2005, driven by an increase of 6.8% in average daily room rate and 2.2 occupancy points. RevPAR performance for the entire portfolio, while strong, was negatively impacted by rebranding and renovation programs at the Fairmont Newport Beach and the Hyatt Regency Century Plaza. Including these hotels, RevPAR increased 9.2%, driven by an increase of 7.4% in average daily rate and 1.2 occupancy points.

Comparable hotel operating profit margins for the second quarter increased 210 basis points (from 30.8% to 28.7%) (see page 11 for a reconciliation of hotel operating income to the comparable GAAP measure).

In addition to the Fairmont Newport Beach and Hyatt Regency Century Plaza, significant renovation work was in process or completed at a number of our hotels which resulted in disruption to second quarter operations. Please see “Capital Expenditures” on page 5 for more detail.

Outlook

The Company is providing guidance at this time but does not undertake to update it for any developments in its business. Achievement of the anticipated results is subject to risks and uncertainties, including those disclosed in the Company’s filings with the Securities and Exchange Commission. The Company has provided guidance for the third quarter of 2006 as well as full year 2006. The Company’s guidance does not include the impact of any possible future asset purchases or sales.

Third Quarter 2006 Outlook

The Company expects comparable hotel RevPAR for the third quarter of 2006 to increase approximately 7% to 9% over the third quarter of 2005. As a result, the Company estimates that for the third quarter of 2006:

• Income available to common stockholders should be approximately $9.9 million to $12.4 million;

• Income available to common stockholders per diluted share should be approximately $0.16 to $0.20;

• EBITDA and Adjusted EBITDA should be approximately $67.5 million to $70.0 million;

• Adjusted FFO available to common stockholders should be approximately $39.8 million to $42.3 million;

• Adjusted FFO available to common stockholders per diluted share should be approximately $0.64 to $0.68;

• Hotel operating profit margins should increase approximately 150 basis points to 200 basis points over the second quarter of 2005; and

• Total capital expenditures for the portfolio should be approximately $35 million to $45 million.

Annual 2006 Outlook

The Company reiterates the previously provided guidance that it expects comparable hotel RevPAR for the full year 2006 to increase approximately 7.5% to 9% over the full year 2005. As a result, the Company estimates that for the full year 2006:

• Income available to common stockholders should be approximately $53.9 million to $58.4 million;

• Income available to common stockholders per diluted share should be approximately $0.87 to $0.95;

• EBITDA and Adjusted EBITDA should be approximately $260.5 million to $265.0 million;

• Adjusted FFO available to common stockholders should be approximately $157.1 million to $161.6 million;

4

• Adjusted FFO available to common stockholders per diluted share should be approximately $2.54 to $2.62;

• Hotel operating profit margins should increase approximately 150 basis points to 200 basis points over the full year 2005; and

• Total capital expenditures should be approximately $130 million to $145 million.

Full year guidance has been negatively impacted by the slow ramp-up of the Fairmont Newport Beach, increased property insurance premiums and an increase in anticipated displacement at the Orlando Renaissance.

Balance Sheet/Liquidity Update

As of June 30, 2006, the Company had approximately $79.2 million of cash and cash equivalents (including restricted cash). The Company also had 14 unencumbered assets. The Company currently has $36 million drawn under its recently closed $200 million unsecured credit facility. Total assets at June 30, 2006 were $2.8 billion, including $2.6 billion of net investments in hotel properties, total debt of $1.5 billion and stockholders’ equity of $1.1 billion.

In April 2006, the Company sold 2.2 million shares of 8.0% Series A Cumulative Redeemable Preferred Stock with a liquidation preference of $25.00 per share for gross proceeds of $55.0 million.

In April 2006, the Company repaid in full the $75.0 million term loan with the proceeds from the Series A Cumulative Redeemable Preferred offering and cash on hand from the refinancing described below.

In April 2006, the Company refinanced the existing mortgage loan secured by the Renaissance Washington D.C. that would have matured in 2008. The Company incurred a loss on the early extinguishment of debt of approximately $2.6 million. The prior loan had a principal balance of $52.9 million, a fixed interest rate of 7.5% and a maturity date of 2008. The new loan is for $135.0 million, has a fixed interest rate of 5.95% and matures in 2021.

In May 2006, the Company completed the acquisition of the 335-room La Jolla Embassy Suites located in San Diego, California, for approximately $100.7 million. The acquisition was primarily financed with a fixed-rate loan totaling $70.0 million at a rate of 6.60%. The loan is interest only for five years and matures in 2019.

In June 2006, the Company completed the acquisition of the 259-room W San Diego located in the heart of downtown San Diego, California, for approximately $96.0 million.

Recent Developments

In July 2006, the Company closed a four-year, $200 million unsecured revolving credit facility. This facility replaces the Company’s $150 million secured revolving credit facility. The interest rate for the new unsecured facility is based on grid pricing with spreads over LIBOR and is 25 basis points lower than the $150 million facility. In addition, the unused fee is 30 basis points lower than the previous facility. Subject to certain conditions, the $200 million facility may be extended for one-year and increased to $300 million.

In July 2006, the Company agreed to sell 4.0 million shares of common stock pursuant to a forward sale agreement with an affiliate of Citigroup Global Markets, Inc. The forward sale agreement fixes the net proceeds to the Company at $27.75 per share, subject to certain adjustments, and gives the Company the right to settle in multiple draws at any time within one year. The net proceeds to the Company assuming physical settlement of the forward sale agreement are expected to be approximately $111 million.

“We are pleased to have taken advantage of the strong financing environment to lock in another $325.0 million of long-term, attractively priced debt and preferred capital in the second quarter”, said Jon Kline, Chief Financial Officer. “In addition, subsequent to quarter-end, we put in place a new four-year $200.0 million credit facility and executed a forward stock sale agreement that provides us with increased financial capacity and flexibility.”

Appointment of Board Committee to Review Management Succession

The Company also announced that its Board of Directors has formed a special committee to identify potential successors to Robert A. Alter, the Company’s President and Chief Executive Officer, who is expected to become Chairman when his employment contract expires in October 2007. The committee has been directed by the Board to consider candidates and has begun this process. While a formal timetable has not been established, the Board’s goal is to name a successor by the end of the year.

Dividend Update

In April 2006, the Company paid a dividend of $0.30 per share to its common stockholders, a dividend of $0.50 per share to its Series A cumulative redeemable preferred stockholders and a dividend of $0.393 per share to its Series C cumulative convertible redeemable preferred stockholders.

During the second quarter of 2006, the Board of Directors of the Company declared a dividend of $0.30 per share payable to its common stockholders. The Company also declared a dividend of $0.50 per share payable to its Series A cumulative redeemable preferred stockholders and a dividend of $0.393 per share payable to its Series C cumulative convertible redeemable preferred stockholders. The dividends were paid on July 17, 2006 to stockholders of record on June 30, 2006. The level of future dividends will be determined by the Company’s quarterly operating results and expected capital requirements.

Non-GAAP Financial Measures

We present the following non-GAAP financial measures that we believe are useful to investors as key measures of our operating performance: (1) Earnings Before Interest Expense, Taxes, Depreciation and Amortization, or EBITDA; (2) Adjusted EBITDA (as defined below); (3) Funds From Operations, or FFO; (4) Adjusted FFO (as defined below); and (5) Hotel Operating Income and Hotel Operating Profit Margin for the purpose of our operating margins.

EBITDA represents income (loss) available to common stockholders before minority interest excluding: (1) preferred stock dividends; (2) interest expense (including prepayment penalties, if any); (3) provision for income taxes, including income taxes applicable to sale of assets; and (4) depreciation and amortization. In addition, we have presented Adjusted EBITDA, which excludes: (1) the impact of any gain or loss from asset sales; (2) impairment charges; and (3) other adjustments we have identified in this release. We believe EBITDA and Adjusted EBITDA are useful to an investor in evaluating our operating performance because they help investors evaluate and compare the results of our operations from period to period by removing the impact of our capital structure (primarily interest expense and preferred stock dividends) and our asset base (primarily depreciation and amortization) from our operating results. We also use EBITDA and Adjusted EBITDA as measures in determining the value of hotel acquisitions and dispositions. A reconciliation and the components of Hotel Operating Income and Hotel Operating Profit Margin are set forth on page 13. We believe Hotel Operating Income and Hotel Operating Profit Margin are also useful to investors in evaluating our property level operating performance.

We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, an industry trade group. The Board of Governors of NAREIT in its March 1995 White Paper (as clarified in November 1999 and April 2002) defines FFO to mean net income (loss) (computed in accordance with GAAP), excluding gains and losses from sales of property, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), and after adjustment for unconsolidated partnerships and joint ventures. We also present Adjusted FFO which excludes prepayment penalties, written-off deferred financing costs, impairment losses and other adjustments we have identified in this release. We believe that the presentation of FFO and Adjusted FFO provide useful information to investors regarding our operating performance because they are a measure of our operations without regard to specified non-cash items such as real estate depreciation and amortization, gain or loss on sale of assets and certain other items which we believe are not indicative of the performance of our underlying hotel properties. We believe that these items are more representative of our asset base and our acquisition and disposition activities than our ongoing operations. We also use FFO as one measure in determining our results after taking into account the impact of our capital structure. A reconciliation of net income (loss) to FFO and Adjusted FFO is set forth on page 10.

We caution investors that amounts presented in accordance with our definitions of EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income may not be comparable to similar measures disclosed by other companies, since not all companies calculate these non-GAAP measures in the same manner. EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income should not be considered as an alternative measure of our net income (loss), operating performance, cash flow or liquidity. EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income may include funds that may not be available for our discretionary use due to functional requirements to conserve funds for capital expenditures and property acquisitions and other commitments and uncertainties. Although we believe that EBITDA, Adjusted EBITDA, FFO, Adjusted FFO and hotel operating income can enhance an investor’s understanding of our results of operations, these non-GAAP financial measures, when viewed individually, are not necessarily a better indicator of any trend as compared to GAAP measures such as net income (loss) or cash flow from operations. In addition, you should be aware that adverse economic and market conditions may harm our cash flow.
