PASADENA, Calif., Oct. 30 /PRNewswire-FirstCall/ -- Alexandria Real Estate Equities, Inc. (NYSE: ARE) today announced operating and financial results for the third quarter ended September 30, 2008.

For the third quarter of 2008, we reported total revenues of $115,280,000 and FFO available to common stockholders of $48,832,000, or $1.53 per share (diluted), compared to total revenues of $102,107,000 and FFO available to common stockholders of $42,723,000, or $1.45 per share (diluted), for the third quarter of 2007. Comparing the third quarter of 2008 to the third quarter of 2007, total revenues increased 13%, FFO available to common stockholders increased 14% and FFO per share (diluted) increased 6%. For the nine months ended September 30, 2008, we reported total revenues of $335,293,000 and FFO available to common stockholders of $143,862,000, or $4.51 per share (diluted), before non-cash impairment charges, compared to total revenues of $290,662,000 and FFO available to common stockholders of $124,675,000, or $4.24 per share (diluted), before a preferred stock redemption charge, for the nine months ended September 30, 2007. Comparing the nine months ended September 30, 2008 to the nine months ended September 30, 2007, total revenues increased 15%, FFO available to common stockholders and FFO per share (diluted) increased 15% and 6%, respectively, before non-cash impairment and preferred stock redemption charges. In the first quarter of 2008, we incurred non-cash impairment charges aggregating $6,635,000, or $0.21 per share (diluted), related to assets "held for sale" and certain investments, and in the first quarter of 2007 we recognized a preferred stock redemption charge of $2,799,000, or $0.10 per share (diluted).

FFO is a non-GAAP measure widely used by publicly traded real estate investment trusts. A reconciliation of GAAP net income available to common stockholders to FFO available to common stockholders and FFO available to common stockholders after supplemental adjustments on both an aggregate and per share (diluted) basis, is included in the financial information accompanying this press release. The primary reconciling item between GAAP net income available to common stockholders and FFO available to common stockholders is depreciation and amortization expense. Depreciation and amortization expense for the three months ended September 30, 2008 and 2007 was $27,447,000 and $24,194,000, respectively. Depreciation and amortization expense for the nine months ended September 30, 2008 and 2007 was $80,260,000 and $70,366,000, respectively. Net income available to common stockholders for the third quarter of 2008 was $21,510,000, or $0.67 per share (diluted), compared to net income available to common stockholders of $20,186,000, or $0.68 per share (diluted), for the third quarter of 2007. Net income available to common stockholders for the third quarter of 2007 included a gain of $1,614,000 on the sale of one property and four land parcels. Excluding gains on sales of properties, net income available to common stockholders for the third quarter of 2007 was $18,572,000, or $0.63 per share (diluted), for the third quarter of 2007. Net income available to common stockholders for the nine months ended September 30, 2008 was $77,573,000, or $2.43 per share (diluted), compared to net income available to common stockholders of $56,628,000, or $1.93 per share (diluted), for the nine months ended September 30, 2007. Net income available to common stockholders for the nine months ended September 30, 2008 included aggregate gains of $20,395,000 on sales of seven properties and non-cash impairment charges aggregating $6,635,000 related to assets "held for sale" and certain investments. Net income available to common stockholders for the nine months ended September 30, 2007 included a gain on sales of three properties and four land parcels of $5,075,000 and a preferred stock redemption charge of $2,799,000. Excluding gains on sales of properties and non-cash impairment and preferred stock redemption charges, net income available to common stockholders for the nine months ended September 30, 2008 was $63,813,000, or $2.00 per share (diluted), compared to net income available to common stockholders of $54,352,000, or $1.85 per share (diluted), for the nine months ended September 30, 2007.

For the third quarter of 2008, we executed a total of 41 leases for approximately 618,000 rentable square feet of space at 26 different properties (excluding month-to-month leases). Of this total, approximately 211,000 rentable square feet related to new or renewal leases of previously leased space and approximately 407,000 rentable square feet related to developed, redeveloped or previously vacant space. Of the 407,000 rentable square feet, approximately 310,000 rentable square feet were delivered from our development or redevelopment programs, with the remaining approximately 97,000 rentable square feet related to previously vacant space. Rental rates for these new or renewal leases were on average approximately 8.2% higher (on a GAAP basis) than rental rates for expiring leases.

For the nine months ended September 30, 2008, we executed a total of 114 leases for approximately 1,696,000 square feet of space at 56 different properties (excluding month-to-month leases). Of this total, approximately 916,000 square feet were for new or renewal leases related to previously leased space and approximately 780,000 square feet were for developed, redeveloped, or previously vacant space. Of the 780,000 square feet, approximately 513,000 square feet were delivered from our redevelopment or development programs, with the remaining approximately 267,000 square feet for previously vacant space. Rental rates for new or renewal leases were on average approximately 14.9% higher (on a GAAP basis) than rental rates for expiring leases.

In August 2008, we announced that Pfizer Inc. entered into a long-term lease for approximately 100,000 square feet, with an option for an additional 50,000 square feet. Pfizer Inc. will locate its Biotherapeutics and Bioinnovation Center in The Alexandria Center for Science and Technology at Mission Bay, San Francisco, California.

In October 2008, we announced that Gilead Sciences, Inc. entered into a long-term lease for approximately 106,000 square feet in Seattle, Washington.

As of September 30, 2008, approximately 89% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes and insurance, common area and other operating expenses, including increases thereto. In addition, as of September 30, 2008, approximately 8% of our leases (on a rentable square footage basis) required the tenants to pay a majority of operating expenses. Additionally, as of September 30, 2008, approximately 92% of our leases (on a rentable square footage basis) provided for the recapture of certain capital expenditures and approximately 94% of our leases (on a rentable square footage basis) contained effective annual rent escalations that were either fixed or based on the consumer price index or another index.

Based on our current view of existing market conditions and certain current assumptions, our updated guidance for FFO per share (diluted) and earnings per share (diluted) is as follows:

                                                                 2008
                                                               ---------
              FFO per share (diluted) (1)                      $5.85 (1)
              Earnings per share (diluted) (2)                 $3.10 (2)
              Non-cash impairment charges recognized
              in the first quarter of 2008                     $0.21

              (1) Includes non-cash impairment charges
                  aggregating $6,635,000, or $0.21 per share
                  (diluted), related to assets "held for sale" as
                  of September 30, 2008 and certain investments.
                  Our guidance for 2008 FFO per share (diluted)
                  after supplemental adjustments for the non-cash
                  impairment charges is $6.06.

              (2) Includes non-cash impairment charges
                  aggregating $6,635,000 and gains on sales of
                  property aggregating $20,395,000.

Funds from Operations

Generally accepted accounting principles ("GAAP") basis accounting for real estate assets utilizes historical cost accounting and assumes real estate values diminish over time. In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Board of Governors of the National Association of Real Estate Investment Trusts ("NAREIT") established the measurement tool of Funds From Operations ("FFO"). Since its introduction, FFO has become a widely used non-GAAP financial measure among real estate investment trusts ("REITs"). We believe that FFO is helpful to investors as an additional measure of the performance of an equity REIT. We compute FFO in accordance with standards established by the Board of Governors of NAREIT in its April 2002 White Paper (the "White Paper") and related implementation guidance, which may differ from the methodology for calculating FFO utilized by other equity REITs, and, accordingly, may not be comparable to such other REITs. The White Paper defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales, plus real estate related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.

We also present FFO after supplemental adjustments which excludes non-cash impairment and preferred stock redemption charges. FFO after supplemental adjustments differs from FFO established by NAREIT and may not be comparable to that of other REITs. We believe FFO after supplemental adjustments provides a meaningful supplemental financial measure.

Neither FFO nor FFO after supplemental adjustments should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions.

The following tables present 1) a reconciliation of net income available to common stockholders, the most directly comparable GAAP financial measure to FFO, to funds from operations available to common stockholders after supplemental adjustments and 2) a reconciliation of earnings per share (diluted) to FFO per share (diluted) after supplemental adjustments, in each case, for the three and nine months ended September 30, 2008 and 2007 (in thousands, except per share data):

     (1) Includes depreciation and amortization for assets "held for sale"
         reflected as discontinued operations (for the periods prior to when
         such assets were classified as "held for sale").
     (2) Gain on sales of property relates to the disposition of one property
         during the second quarter 2008, six properties during the first
         quarter 2008, four land parcels and one property during the third
         quarter 2007, one property during the second quarter 2007, and one
         property during the first quarter 2007. Gain on sales of property is
         included in the income statement in income from discontinued
         operations, net.
     (3) During the first quarter of 2007, we redeemed our 9.10% series B
         cumulative redeemable preferred stock.  Accordingly, in compliance
         with FASB Emerging Issues Task Force D-42 ("EITF Topic D-42"), we
         recorded a charge of $2,799,000, or $0.10 per share (diluted), in the
         first quarter of 2007 for costs related to the redemption of our
         series B preferred stock.
     (4) In March 2008, we recognized aggregate non-cash impairment charges of
         approximately $1,985,000 for other-than-temporary declines in the
         fair value of certain investments and non-cash impairment charges of
         approximately $4,650,000 on two properties "held for sale". One
         property was an industrial building located in a suburban submarket
         south of Boston and the other property was an office building located
         in the San Diego market. The non-cash impairment charges recognized
         in March 2008 on these two properties are classified in income from
         discontinued operations, net.

    (a) The historical results above exclude the results of assets "held for
        sale" which have been classified as discontinued operations.
    (b) See page 5 for a reconciliation of earnings per share (diluted) to FFO
        per share (diluted) and FFO per share (diluted) after supplemental
        adjustments.
    (c) Dividend payout ratio (common stock) is the ratio of the absolute
        dollar amount of dividends on our common stock (common stock shares
        outstanding on the respective record date multiplied by the related
        dividend per share) to funds from operations after supplemental
        adjustments for the respective quarter.
    (d) As of September 30, 2008, properties undergoing development and
        redevelopment and land held for development for which capitalization
        of interest is required pursuant to Statement of Financial Accounting
        Standards No. 34, "Capitalization of Interest Cost" ("SFAS 34"),
        approximated $1.4 billion.  This amount is classified as properties
        undergoing development and redevelopment and land held for development
        on our balance sheet.  As of September 30, 2008, the weighted average
        interest rate used in the calculation of capitalized interest required
        pursuant to SFAS 34 was approximately 5.50%. SFAS 34 requires the
        interest rate for capitalization to be based on applicable interest
        costs related to borrowings outstanding during the period, including
        the impact of interest rate swap agreements, debt premiums/discounts
        and amortization of loan fees.
    (e) Includes properties "held for sale" during the applicable periods such
        assets were "held for sale." As of September 30, 2008, one property
        with approximately 24,867 rentable square feet was classified as "held
        for sale."
    (f) During the second quarter of 2008, we sold one asset located in the
        San Diego market. During the first quarter of 2008, we sold six
        properties and transferred one property from operating assets to
        embedded future development opportunities. During the fourth quarter
        of 2007, we sold one property and transferred two properties from
        operating assets to embedded future development opportunities. During
        the third quarter of 2007, we sold one property located in the New
        Jersey/Suburban Philadelphia market and four land parcels to the
        Massachusetts Institute of Technology.
    (g) Debt to total market capitalization is the ratio of our share of total
        debt (secured notes payable, unsecured line of credit and unsecured
        term loan and unsecured convertible notes) to total market
        capitalization. Total market capitalization is equal to outstanding
        shares of series C preferred stock and common stock multiplied by the
        related closing price at the end of each period presented, plus series
        D convertible preferred stock at liquidation value, plus our share of
        total debt.

    (1) The weighted average interest rate is calculated based on outstanding
        debt as of September 30, 2008.
    (2) Includes minority interests' share of scheduled principal maturities
        of approximately $42.4 million, of which approximately $20.4 million
        and $21.1 million mature in 2009 and thereafter, respectively.
    (3) The weighted average interest rate is calculated based on outstanding
        debt as of December 31st of the year immediately preceding the year
        presented.
    (4) Our borrowing capacity and financial covenants under our unsecured
        line of credit and unsecured term loan are not directly dependent or
        variable based upon our stock price.  Interest on outstanding
        borrowings under our unsecured credit facility is based upon LIBOR
        plus 1.00% to 1.45% depending on our leverage or the higher of the
        Federal Funds rate plus 0.50% or Bank of America's ("BofA") prime rate
        plus 0.0% to 0.25% depending on our leverage.  As of September 30,
        2008, one-month LIBOR was 3.93%, the Federal Funds rate was 2.00%, and
        BofA's prime rate was 5.00%.  The Federal Funds Rate and BofA's
        prime rate decreased to 1.50% and 4.50%, respectively, effective
        October 8, 2008.  In October 2008, we elected prime based rates for a
        portion of our unhedged variable rate debt when the prime based rate
        was lower than the LIBOR based rate.
    (5) The unsecured line of credit matures in October 2010 and may be
        extended at our sole option for an additional one year period to
        October 2011. The unsecured term loan matures in October 2011 and may
        be extended at our sole option for an additional one year period to
        October 2012.
    (6) On or after January 15, 2012, we have the right to redeem our 3.70%
        unsecured convertible notes, in whole or in part, at any time from
        time to time, for cash equal to 100% of the principal amounts of the
        notes to be redeemed plus any accrued and unpaid interest to, but
        excluding, the redemption date.  Holders of the notes may require us
        to repurchase their notes, in whole or in part, on January 15, 2012,
        2017 and 2022 for cash equal to 100% of the principal amount of the
        notes to be purchased plus any accrued and unpaid interest to, but
        excluding, the repurchase date.  Additional information regarding our
        unsecured convertible notes is contained in our Form 10-K filed with
        the Securities and Exchange Commission.
    (7) Represents the weighted average contractual interest rate plus the
        impact of debt premiums/discounts and our interest rate swap
        agreements. The weighted average interest rate excludes bank fees and
        amortization of loan fees. See page 9 for further details of our
        interest rate swap agreements.

    (1) The interest pay rates represent the interest rate we will pay for one
        month LIBOR under the respective interest rate swap agreement. These
        rates do not include any spread in addition to one month LIBOR that is
        due monthly as interest expense.

    In October 2008, we entered into three additional interest rate swap
    agreements with notional amounts totaling $275 million at fixed interest
    pay rates ranging from 2.750% to 3.119%.  The swap agreements are
    effective in October 2008 and September 2009 and have termination dates
    ranging from December 2009 to January 2011.

    NOTE:  This summary represents operating data for all properties that were
    fully operating for the entire periods presented for the quarter periods
    (the "Third Quarter Same Properties") and for the Nine Month periods (the
    "Nine Months Same Properties").  Same property occupancy for the quarters
    ended September 30, 2008 and 2007 was 96.0% and 95.1%, respectively.  Same
    Property Occupancy for the nine months ended September 30, 2008 and 2007
    was 95.9% and 95.7%, respectively. Properties undergoing redevelopment are
    excluded from same property results.


    (1) Revenue less operating expenses computed in accordance with GAAP is
        total revenue associated with the Third Quarter Same Properties and
        Nine Months Same Properties, as applicable (excluding lease
        termination fees, if any), less property operating expenses.  Under
        GAAP, rental revenue is recognized on a straight-line basis over the
        respective lease terms.  Revenue less operating expenses on a cash
        basis is total revenue associated with the Third Quarter Same
        Properties and Nine Months Same Properties (excluding lease
        termination fees, if any), less property operating expenses, adjusted
        to exclude the effect of straight-line rent adjustments required by
        GAAP.  Straight-line rent adjustments for the quarters ended September
        30, 2008 and 2007 for the Third Quarter Same Properties were
        $1,467,000 and $3,204,000, respectively. Straight-line rent
        adjustments for the nine months ended September 30, 2008 and 2007 for
        the Nine Months Same Properties were $4,166,000 and $10,190,000,
        respectively.  We believe that revenue less operating expenses on a
        cash basis is helpful to investors as an additional measure of
        operating performance because it eliminates straight-line rent
        adjustments to rental revenue.

    (2) Fees received from tenants in connection with termination of their
        leases, if any, are excluded from revenue in the Summary of Same
        Property Comparisons. As of September 30, 2008, approximately 89% of
        our leases (on a square footage basis) were triple net leases,
        requiring tenants to pay substantially all real estate taxes and
        insurance, common area and other operating expenses, including
        increases thereto. In addition, as of September 30, 2008,
        approximately 8% of our leases (on a square footage basis) required
        the tenants to pay a majority of operating expenses.

    Our redevelopment program involves ongoing activities necessary
    for the permanent change of use of applicable redevelopment
    space to office/laboratory space. Spaces currently built out
    with laboratory improvements are generally not placed into our
    value-add redevelopment program. As required under GAAP,
    interest and other costs directly related and essential to the
    project are capitalized on redevelopment properties on the basis
    allocable only to that portion of space undergoing
    redevelopment. In addition to properties undergoing
    redevelopment, as of September 30, 2008, our asset base
    contained embedded opportunities for future permanent change of
    use to office/laboratory space through redevelopment aggregating
    approximately 1,588,000 rentable square feet. See Summary of
    Embedded Future Development and Redevelopment Square Footage on
    page 18.

        (1) This project also includes site work and a multi-story
            below and above ground parking structure to support both
            the existing building undergoing redevelopment and an
            additional building targeted for development in the
            future.  The entitlement process for this project was
            completed in 2007.

    In accordance with Statement of Financial Accounting Standards No. 34,
    "Capitalization of Interest Cost" ("SFAS 34") and Statement of Financial
    Accounting Standards No. 67, "Accounting for Costs and Initial Rental
    Operations of Real Estate Projects" ("SFAS 67"), we are required to
    capitalize direct construction, including pre-construction costs,
    interest, property taxes, insurance and other costs directly related and
    essential to the construction of a project while activities are ongoing to
    prepare an asset for its intended use.  Pre-construction costs include
    costs related to the development of plans and the process of obtaining
    entitlements and permits from government authorities. Costs incurred after
    a project is substantially complete and ready for its intended use are
    expensed as incurred. Should development, redevelopment or construction
    activity cease, construction costs, including interest, would no longer be
    eligible for capitalization, under SFAS 34 and SFAS 67, and would be
    expensed as incurred.

    (1) Our aggregate construction costs to date approximate $195 per rentable
        square foot.  Amount excludes our investment per square foot in land.
    (2) The joint venture has decided to reposition the project for lease to a
        single technology and/or manufacturing tenant.
    (3) Marketing; First lease for 5% awaiting tenant Board action and hiring

    The embedded future development and redevelopment square footage shown
    above represents future ground-up development projects and future
    redevelopment (permanent change in use of applicable space to
    office/laboratory space) projects. A significant portion of our embedded
    future development square footage is in the development/pre-construction
    phase (entitlement, permitting, design, etc.). See discussion on SFAS 34
    and SFAS 67 on page 17. Commencement of construction will depend on
    numerous factors, including the successful completion of development/pre-
    construction activities and management's assessment of overall economic,
    credit, and market conditions. As required under GAAP, direct
    construction, interest, property taxes, insurance and other costs directly
    related and essential to the development/pre-construction, or construction
    of a project, is mandated to be capitalized during pre-construction when
    activities are ongoing to bring these assets to their intended use.


    (1) Development/pre-construction square footage is included in Total
        Embedded Development Square Footage shown above.
    (2) In addition, we have the right to develop an additional parcel in New
        York City with approximately 442,000 rentable square feet. This square
        footage is not included in the embedded development square footage
        shown above.

                             Summary of Capital Costs
                     For the Nine Months Ended September 30, 2008

                                (In thousands)

             Property-related capital expenditures (1)       $    1,145

             Leasing costs (2)                               $    1,058

             Property-related costs (3)                      $  306,111


    (1) Property-related capital expenditures include all major capital and
        recurring capital expenditures except capital expenditures that are
        recoverable from tenants, revenue-enhancing capital expenditures, or
        costs related to the redevelopment of a property.  Major capital
        expenditures consist of roof replacements and HVAC systems which are
        typically identified and considered at the time the property is
        acquired.  Capital expenditures fluctuate in any given period due to
        the nature, extent or timing of improvements required and the extent
        to which they are recoverable from tenants.  Approximately 92% of our
        leases (based on rentable square feet) provide for the recapture of
        certain capital expenditures (such as HVAC systems maintenance and/or
        replacement, roof replacement and parking lot resurfacing).  In
        addition, we implement an active preventative maintenance program at
        each of our properties to minimize capital expenditures.

    (2) Leasing costs consist of tenant improvements and leasing commissions
        related to leasing of acquired vacant space and second generation
        space.

    (3) Amount includes leasing costs related to development and redevelopment
        projects.
