Equity Residential Reports First Quarter 2010 Results

Company Release - 4/28/2010

Same Store Revenues Exceeding Company's Expectations

CHICAGO--(BUSINESS WIRE)-- Equity Residential (NYSE: EQR) today reported results for the quarter ended March 31, 2010. All per share results are reported on a fully-diluted basis.

"We are very pleased with our same store revenue results for the quarter and encouraged by the improving fundamentals we are seeing across all of our markets," said David J. Neithercut, Equity Residential's President and CEO. "If these trends continue, we expect sequential same store revenues to be positive as soon as the second quarter and we should achieve both same store revenue and FFO (funds from operations) results for the year at the upper end of our guidance ranges."

First Quarter 2010

For the first quarter of 2010, the company reported earnings of $0.18 per share compared to $0.28 per share in the first quarter of 2009.

FFO for the quarter ended March 31, 2010 was $0.51 per share excluding the negative impact of property acquisition costs previously budgeted to occur in the second quarter and unexpected storm related costs as a result of severe snow on the East Coast and heavy rains in California and Arizona. Reported FFO for the period including these items was $0.49 per share.

The difference between the company's first quarter 2010 FFO of $0.49 per share and the first quarter 2009 FFO of $0.57 per share is primarily due to:

    --  a negative impact of approximately $0.09 per share from lower total
        property net operating income (NOI) driven by lower same store NOI,
        inclusive of the impact of the unexpected storm related costs mentioned
        above, and dilution from the company's 2009 transaction activity
        partially offset by the positive impact of NOI from lease-up activity;
    --  a negative impact of approximately $0.02 per share from accelerated
        property acquisition and other miscellaneous costs; and
    --  a positive impact of approximately $0.03 per share from lower total
        interest expense as a result of the company's debt tenders in 2009.

Same Store Results

On a same store first quarter to first quarter comparison, which includes 117,512 apartment units, revenues decreased 2.9%, expenses increased 1.5% and NOI decreased 5.6%. Same store revenue results were impacted by the following, all of which were better than company expectations:

    --  a 100 basis point increase in occupancy to 94.7%;
    --  a 170 basis point decrease in turnover;
    --  the spread between expiring lease rates and net effective new lease
        rates was less than expected, in part, because some markets turned
        positive; and
    --  renewal lease rate increases across the company's portfolio.

Acquisitions/Dispositions

During the first quarter of 2010, the company acquired six properties, consisting of 1,467 apartment units, for an aggregate purchase price of $639.3 million at an average capitalization (cap) rate of 5.6% and one land parcel, located adjacent to one of the company's properties in Arlington, Virginia, for approximately $12.0 million.

Since the end of the first quarter, the company acquired one property, the previously announced acquisition of 425 Mass in Washington, D.C., for a purchase price of approximately $166.8 million.

During the first quarter of 2010, the company sold eight consolidated properties, consisting of 2,011 apartment units, for an aggregate sale price of $145.9 million at an average cap rate of 7.5% generating an unlevered internal rate of return (IRR) of 9.4%. The company has not sold any properties since the end of the first quarter.

At-The-Market (ATM) Share Offering Program

During the first quarter of 2010, the company issued approximately 1.1 million common shares at an average price of $33.87 per share for total consideration of approximately $35.8 million under its ATM Share Offering Program. The company has approximately 12.4 million shares available for issuance under this program and has not issued any such shares since January 14, 2010.

Second Quarter 2010 Guidance

The company has established an FFO guidance range of $0.53 to $0.57 per share for the second quarter of 2010. The primary drivers of the difference between the company's first quarter 2010 actual FFO of $0.49 per share and the midpoint of the second quarter 2010 guidance range of $0.55 per share are:

    --  a positive impact of approximately $0.03 per share from same store NOI;
    --  a positive impact of approximately $0.02 per share from 2010
        acquisitions and lease up activity; and
    --  a positive impact of approximately $0.01 per share from the timing of
        property acquisition costs.

Equity Residential expects to announce second quarter 2010 results on Wednesday, July 28, 2010 and host a conference call to discuss those results at 10:00 a.m. CT on Thursday, July 29, 2010.

     The National Association of Real Estate Investment Trusts ("NAREIT")
     defines funds from operations ("FFO") (April 2002 White Paper) as net
     income (computed in accordance with accounting principles generally
     accepted in the United States ("GAAP")), excluding gains (or losses) from
     sales of depreciable property, plus depreciation and amortization, and
     after adjustments for unconsolidated partnerships and joint ventures.
     Adjustments for unconsolidated partnerships and joint ventures will be
     calculated to reflect funds from operations on the same basis. The April
     2002 White Paper states that gain or loss on sales of property is excluded
     from FFO for previously depreciated operating properties only. Once the
(1)  Company commences the conversion of units to condominiums, it
     simultaneously discontinues depreciation of such property. FFO available to
     Common Shares and Units is calculated on a basis consistent with net income
     available to Common Shares and reflects adjustments to net income for
     preferred distributions and premiums on redemption of preferred shares in
     accordance with accounting principles generally accepted in the United
     States. The equity positions of various individuals and entities that
     contributed their properties to the Operating Partnership in exchange for
     OP Units are collectively referred to as the "Noncontrolling Interests -
     Operating Partnership". Subject to certain restrictions, the Noncontrolling
     Interests - Operating Partnership may exchange their OP Units for EQR
     Common Shares on a one-for-one basis.

     The Company believes that FFO and FFO available to Common Shares and Units
     are helpful to investors as supplemental measures of the operating
     performance of a real estate company, because they are recognized measures
     of performance by the real estate industry and by excluding gains or losses
     related to dispositions of depreciable property and excluding real estate
     depreciation (which can vary among owners of identical assets in similar
     condition based on historical cost accounting and useful life estimates),
     FFO and FFO available to Common Shares and Units can help compare the
     operating performance of a company's real estate between periods or as
(2)  compared to different companies. FFO and FFO available to Common Shares and
     Units do not represent net income, net income available to Common Shares or
     net cash flows from operating activities in accordance with GAAP.
     Therefore, FFO and FFO available to Common Shares and Units should not be
     exclusively considered as alternatives to net income, net income available
     to Common Shares or net cash flows from operating activities as determined
     by GAAP or as a measure of liquidity. The Company's calculation of FFO and
     FFO available to Common Shares and Units may differ from other real estate
     companies due to, among other items, variations in cost capitalization
     policies for capital expenditures and, accordingly, may not be comparable
     to such other real estate companies.

    The Company's primary financial measure for evaluating each of its apartment
    communities is net operating income ("NOI"). NOI represents rental income less
    property and maintenance expense, real estate tax and insurance expense, and
(1) property management expense. The Company believes that NOI is helpful to
    investors as a supplemental measure of the operating performance of a real
    estate company because it is a direct measure of the actual operating results
    of the Company's apartment communities.

(2) Average rental rate is defined as total rental revenues divided by the
    weighted average occupied units for the period.

(1) Project and unit counts exclude all uncompleted development projects until those projects are
substantially completed. See the Consolidated Development Projects schedule for more detail.

(2) All debt is non-recourse to the Company with the exception of $42.2 million in mortgage debt on
various development projects. In addition, $66.0 million in mortgage debt on one development project
will become recourse to the Company upon completion of that project.

(3) Represents the Company's current economic ownership interest.

(4) Projects included here are substantially complete. However, they may still require additional
exterior and interior work for all units to be available for leasing.

(5) Unconsolidated debt maturities and rates are as follows: $70.0 million (net of $42.6 million in
cash collateral held by the lender), May 1, 2010, 8.33%; $121.0 million, December 1, 2010, 7.54%;
$143.8 million, March 1, 2011, 6.95%; and $11.9 million, July 1, 2019, 5.305%. On April 30, 2010, the
Company anticipates acquiring the 75% equity interest it does not currently own in seven of the
unconsolidated properties containing 1,811 units in exchange for an approximate $30.0 million payment
to its partner. In addition, the Company will repay the net $70.0 million mortgage loan, which
matures on May 1, 2010, concurrent with closing using proceeds drawn from the Company's line of
credit. The total consideration paid by the Company represents an implied 8.2% cap rate.

Definitions and Footnotes for Pages 22 and 23

     The National Association of Real Estate Investment Trusts ("NAREIT")
     defines funds from operations ("FFO") (April 2002 White Paper) as net
     income (computed in accordance with accounting principles generally
     accepted in the United States ("GAAP")), excluding gains (or losses) from
     sales of depreciable property, plus depreciation and amortization, and
     after adjustments for unconsolidated partnerships and joint ventures.
     Adjustments for unconsolidated partnerships and joint ventures will be
     calculated to reflect funds from operations on the same basis. The April
     2002 White Paper states that gain or loss on sales of property is excluded
     from FFO for previously depreciated operating properties only. Once the
(1)  Company commences the conversion of units to condominiums, it
     simultaneously discontinues depreciation of such property. FFO available to
     Common Shares and Units is calculated on a basis consistent with net income
     available to Common Shares and reflects adjustments to net income for
     preferred distributions and premiums on redemption of preferred shares in
     accordance with accounting principles generally accepted in the United
     States. The equity positions of various individuals and entities that
     contributed their properties to the Operating Partnership in exchange for
     OP Units are collectively referred to as the "Noncontrolling Interests -
     Operating Partnership". Subject to certain restrictions, the Noncontrolling
     Interests - Operating Partnership may exchange their OP Units for EQR
     Common Shares on a one-for-one basis.

     The Company believes that FFO and FFO available to Common Shares and Units
     are helpful to investors as supplemental measures of the operating
     performance of a real estate company, because they are recognized measures
     of performance by the real estate industry and by excluding gains or losses
     related to dispositions of depreciable property and excluding real estate
     depreciation (which can vary among owners of identical assets in similar
     condition based on historical cost accounting and useful life estimates),
     FFO and FFO available to Common Shares and Units can help compare the
     operating performance of a company's real estate between periods or as
(2)  compared to different companies. FFO and FFO available to Common Shares and
     Units do not represent net income, net income available to Common Shares or
     net cash flows from operating activities in accordance with GAAP.
     Therefore, FFO and FFO available to Common Shares and Units should not be
     exclusively considered as alternatives to net income, net income available
     to Common Shares or net cash flows from operating activities as determined
     by GAAP or as a measure of liquidity. The Company's calculation of FFO and
     FFO available to Common Shares and Units may differ from other real estate
     companies due to, among other items, variations in cost capitalization
     policies for capital expenditures and, accordingly, may not be comparable
     to such other real estate companies.

     Non-comparable items are those items included in FFO that by their nature
(3)  are not comparable from period to period, such as net incremental gain on
     sales of condominium units, impairment charges, debt extinguishment costs
     and redemption premiums on Preferred Shares/Preference Interests.

     Earnings represents net income per share calculated in accordance with
     accounting principles generally accepted in the United States. Expected
(4)  earnings is calculated on a basis consistent with actual earnings. Due to
     the uncertain timing and extent of property dispositions and the resulting
     gains/losses on sales, actual earnings could differ materially from
     expected earnings.
