PASADENA, CA. – October 25, 2011 – Alexandria Real Estate Equities, Inc. (NYSE: ARE) today announced financial and operating results for the third quarter ended September 30, 2011.

Financial Results

Revenue Trend – Past

For the three months ended September 30, 2011, we reported an increase in total revenues to $143,427,000 from $142,918,000 for the three months ended June 30, 2011.  During the three months ended September 30, 2011, total rental revenue declined approximately $3 million. The decline in rental revenue was primarily due to the transition of three properties. Approximately $2 million of the decline in rental revenue related to 5200 Research Place, a property transitioning from a short term sale lease back with Biogen Idec Inc. to a 20 year triple net lease with Illumina, Inc. The original short-term lease with Biogen Idec Inc. was for an original term of 15 months. Upon execution of a lease with Illumina, Inc., we amended the short term lease with Biogen Idec Inc. in order to deliver space to Illumina, Inc. at an earlier date. The primary reason for the $2 million decline in rental revenue at this property was due to a $1.7 million decline in amortization of below market lease revenue. Annualized base rent per square foot at 5200 Research Place is expected to be approximately $38.26 per rentable square foot in the three months ended December 31, 2011, pursuant to a 20 year lease with Illumina, Inc. An additional $1 million decline in rental revenue from the three months ended June 30, 2011, to the three months ended September 30, 2011, was primarily due to 1) a decline in rental revenue for an office property located in Cambridge that will undergo a conversion into a laboratory building through redevelopment beginning in October 2011, and 2) another property located in the suburbs of Boston, in transition during the quarter from a prior tenant to a new tenant, resulting in a temporary decline in rental revenue. As of October 2011, the new tenant was in full occupancy of this property.

Revenue Trend – Future

Rental revenue and net operating income are projected to increase significantly quarter to quarter from the three months ended December 31, 2011, to the three months ended December 31, 2012.  Annualized three months ended December 31, 2012, net operating income, when compared to annualized three months ended December 31, 2011, net operating income, is expected to increase by approximately $42 to $47 million primarily related to current and future redevelopment and development projects, a significant amount which is pre-leased.  Additionally, the increase in net operating income is also due to annual contractual steps in cash rents, recent and anticipated leasing, and lease-up of vacant space.

Funds from Operations and Net Income Attributable to Alexandria Real Estate Equities, Inc.’s Common Stockholders

For the three months ended September 30, 2011, we reported FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $67,972,000, or $1.11 per share (diluted), before loss on early extinguishment of debt and non-cash impairment charge, compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $55,151,000, or $1.11 per share (diluted), before loss on early extinguishment of debt, for the three months ended September 30, 2010.  For the nine months ended September 30, 2011, we reported FFO attributed to Alexandria Real Estate Equities, Inc.’s common stockholders of $198,237,000, or $3.40 per share (diluted), before loss on early extinguishment of debt and non-cash impairment charge, compared to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $163,686,000, or $3.29 per share (diluted), before loss on early extinguishment of debt, for the nine months ended September 30, 2010.  During the nine months ended September 30, 2011, we recognized an aggregate loss on early extinguishment of debt of approximately $6.5 million related to the repurchases, in privately negotiated transactions, of approximately $217.1 million of certain of our 3.70% unsecured convertible notes and the partial and early repayment of our unsecured term loan.  In addition, we recognized a non-cash impairment charge of approximately $1.0 million related to one property during the nine months ended September 30, 2011.  We sold this property to a user in October 2011 for approximately $2.9 million.  Including the aggregate loss on early extinguishment of debt and non-cash impairment charge, FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the three and nine months ended September 30, 2011, was $64,274,000, or $1.05 per share (diluted), and 190,826,000, or $3.27 per share (diluted), respectively.

Financial Results (continued)

FFO is a non-GAAP measure widely used by real estate investment trusts.  We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”) in its April 2002 White Paper and related implementation guidance.  A reconciliation of net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders in accordance with United States generally accepted accounting principles (“GAAP”) to FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders is included in the financial information accompanying this press release.  The primary reconciling items between GAAP net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders and FFO attributable to Alexandria Real Estate Equities, Inc.’s common stockholders are depreciation and amortization expense and gain on sales of property. Depreciation and amortization expense for the three months ended September 30, 2011 and 2010, was $39,990,000 and $32,009,000, respectively.  Depreciation and amortization expense for the nine months ended September 30, 2011 and 2010, was $117,060,000 and $92,089,000, respectively.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the three months ended September 30, 2011, was $24,662,000 or $0.40 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $22,235,000, or $0.45 per share (diluted), for the three months ended September 30, 2010.  Net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders for the nine months ended September 30, 2011, was $75,013,000, or $1.29 per share (diluted), compared to net income attributable to Alexandria Real Estate Equities, Inc.’s common stockholders of $22,467,000, or $0.49 per share (diluted), for the nine months ended September 30, 2010.

Leasing Activity

For the three months ended September 30, 2011, we executed a total of 56 leases for approximately 985,000 rentable square feet at 40 different properties (excluding month-to-month leases).  Of this total, approximately 402,000 rentable square feet related to new or renewal leases of previously leased space (renewed/re-leased space) and approximately 583,000 rentable square feet related to developed, redeveloped, or previously vacant space.  Of the 583,000 rentable square feet, approximately 458,000 rentable square feet were related to our development or redevelopment programs, with the remaining approximately 125,000 rentable square feet related to previously vacant space.  Rental rates for these new or renewal leases (renewed/re-leased space) were on average approximately 2.8% higher on a GAAP basis than rental rates for the respective expiring leases.

For the nine months ended September 30, 2011, we executed a total of 143 leases for approximately 2,265,000 rentable square feet at 60 different properties (excluding month-to-month leases).  Of this total, approximately 1,171,000 rentable square feet related to new or renewal leases of previously leased space (renewed/re-leased space) and approximately 1,094,000 rentable square feet related to developed, redeveloped, or previously vacant space.  Of the 1,094,000 rentable square feet, approximately 634,000 rentable square feet were related to our development or redevelopment programs, and the remaining approximately 460,000 rentable square feet were related to previously vacant space.  Rental rates for these new or renewal leases (renewed/re-leased space) were on average approximately 2.5% higher on a GAAP basis than rental rates for the respective expiring leases.

As of September 30, 2011, approximately 95% of our leases (on a rentable square footage basis) were triple net leases, requiring tenants to pay substantially all real estate taxes, insurance, utilities, common area, and other operating expenses (including increases thereto) in addition to base rent.  Additionally, 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 indexed based on the consumer price index or another index.

Investment Grade Rating

In July 2011, we received a Baa2 (stable outlook) and a BBB- (stable outlook) investment grade rating from two major rating agencies.  Key strengths of our balance sheet and business which highlight our investment grade credit profile include, among others, solid liquidity on balance sheet, diverse and credit worthy tenant base, well located properties proximate to leading research institutions, favorable lease terms, solid and stable occupancy and cash flows, and proven life science and real estate expertise.  This significant milestone broadens our access to another key source of capital and allows us to continue to pursue our long-term capital, investment, and operating strategies.  Issuance of unsecured bonds will allow us to transition bank related debt financing to unsecured bonds, variable rate debt to fixed rate debt, and short tenured debt to long tenured debt.

Unsecured Credit Facility

In January 2011, we entered into a third amendment (the “Third Amendment”) to our second amended and restated credit agreement dated October 31, 2006, as further amended on December 1, 2006 and May 2, 2007 (the “Prior Credit Agreement,” and as amended by the Third Amendment, the “Amended Credit Agreement”), with Bank of America, N.A., as administrative agent, and certain lenders. The Third Amendment amended the Prior Credit Agreement to, among other things, increase the maximum permitted borrowings under the unsecured line of credit from $1.15 billion to $1.5 billion, plus a $750 million unsecured term loan (the “2012 Unsecured Term Loan” and together with the unsecured line of credit, the “Unsecured Credit Facility”) and provided an accordion option to increase commitments under the Unsecured Credit Facility by up to an additional $300 million.  Borrowings under the Unsecured Credit Facility bear interest at LIBOR or the specified base rate, plus in either case a margin specified in the Amended Credit Agreement (the “Applicable Margin”).  The Applicable Margin for LIBOR borrowings outstanding under the revolving credit facility was 2.3% as of September 30, 2011.  The Applicable Margin for the LIBOR borrowings under the 2012 Unsecured Term Loan was not amended in the Third Amendment.

Unsecured Credit Facility (continued)

Under the Third Amendment, the maturity date for the unsecured line of credit is January 2015, assuming we exercise our sole right under the amendment to extend this maturity date twice by an additional six months after each exercise.  The maturity date of the 2012 Unsecured Term Loan is October 2012.  The Third Amendment modified certain financial covenants with respect to the Unsecured Credit Facility, including the fixed charge coverage ratio, secured debt ratio, leverage ratio, and minimum book value, and added covenants relating to an unsecured leverage ratio and unsecured debt yield.

2016 Unsecured Term Loan

In February 2011, we entered into a $250 million unsecured term loan.  In June 2011, we amended this $250 million unsecured term loan (as amended, the “2016 Unsecured Term Loan”) to, among other things, increase the borrowings from $250 million to $750 million and to extend the maturity from January 2015 to June 2016, assuming we exercise our sole right to extend the maturity date by one year.  Borrowings under the 2016 Unsecured Term Loan bear interest at LIBOR or the specified base rate, plus in either case a margin specified in the amended unsecured term loan agreement.  The applicable margin for the LIBOR borrowings under the 2016 Unsecured Term Loan as of September 30, 2011, was 1.65%.  Under the 2016 Unsecured Term Loan agreement, the financial covenants were not amended and are identical to the financial covenants required under our existing Unsecured Credit Facility.  The 2016 Unsecured Term Loan may be repaid at any date prior to maturity without a prepayment penalty.  The net proceeds from this 2016 Unsecured Term Loan were used to reduce outstanding borrowings on the 2012 Unsecured Term Loan from $750 million to $250 million.  As a result of this early repayment, in the three and six months ended June 30, 2011, we recognized a loss on early extinguishment of debt of approximately $1.2 million related to the write-off of unamortized loan fees.

3.70% Unsecured Convertible Notes

During the three months ended September 30, 2011, we repurchased, in privately negotiated transactions, approximately $121.1 million of certain of our 3.70% unsecured convertible notes at an aggregate cash price of approximately $122.8 million.  As a result of these repurchases, we recognized an aggregate loss on early extinguishment of debt of approximately $2.7 million.  As of September 30, 2011, approximately $84.3 million of our 3.70% unsecured convertible notes was outstanding, net of approximately $0.5 million of unamortized discount.

During the three months ended March 31, 2011, we repurchased, in privately negotiated transactions, approximately $96.1 million of certain of our 3.70% unsecured convertible notes at an aggregate cash price of approximately $98.6 million.  As a result of these repurchases, we recognized an aggregate loss on early extinguishment of debt of approximately $2.5 million during the three months ended March 31, 2011.

Acquisitions

In June 2011, we acquired 285 Bear Hill Road, a 26,270 rentable square foot office property located in the Greater Boston market, for approximately $3.9 million.  We plan to begin the redevelopment of this property into life science laboratory space in the three months ended December 31, 2011.  Based on our view of existing market conditions and certain assumptions at the time of the acquisition, we expect to achieve a stabilized yield on a GAAP and cash basis for this property of approximately 8.6% and 8.0%, respectively.  Stabilized yield on cost is calculated as the quotient of net operating income and our investment in the property at stabilization (“Stabilized Yield”).

In April 2011, we acquired 409 and 499 Illinois Street, a newly and partially completed world-class 453,256 rentable square foot laboratory/office development project located on a highly desirable waterfront location in Mission Bay, San Francisco, for approximately $293 million.  409 Illinois Street is a 241,659 rentable square foot tower that is 97% leased to a life science company through November 2023.  499 Illinois Street is a vacant 211,597 rentable square foot tower in shell condition for which we plan to complete the development.  Based on our view of existing market conditions and certain assumptions at the time of the acquisition, we expect to achieve a Stabilized Yield on a GAAP and cash basis for this property in the range of 7.2% to 7.6% and 6.5% to 7.0%, respectively.

Dispositions

In August 2011, we sold a parcel of land located in San Diego, California for approximately $17.3 million at a gain of $46,000.  The buyer is expected to construct a building with approximately 249,000 rentable square feet, representing a sale price of approximately $70 per rentable square foot.

During the three months ended September 30, 2011, 13-15 DeAngelo Drive, a vacant 30,000 rentable square foot property, located in the suburbs of Boston, Massachusetts, met the criteria for classification as “held for sale.”  This property was occupied by a credit life science tenant through June 30, 2011.  Upon move out, a user for the building presented an offer for the purchase of the building in the three months ended September 30, 2011.  As a result, we recognized an impairment charge of approximately $1.0 million in the three months ended September 30, 2011, to adjust the carrying value to the estimated fair value less costs to sell.  In October 2011, we sold 13-15 DeAngelo Drive to that user, for approximately $2.9 million, representing a sale price of approximately $97 per rentable square foot.

Development

In August 2011, we completed the ground-up development of 7 Triangle Drive, a 97,000 rentable square foot single-tenant building located in the Research Triangle Park market, which is currently 100% leased as of September 30, 2011.  Our Stabilized Yield on a GAAP and cash basis for this property was approximately 9.3% and 8.3%, respectively.

In July 2011, we executed a new lease for a 307,000 rentable square feet ground-up development with Biogen Idec, Inc. at Alexandria CenterTM at Kendall Square.  The ground breaking for this project will occur in late October 2011, and we will add the project to our disclosure of active ground-up development for the three months ended December 31, 2011.

Note Regarding Funds from Operations

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 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.  FFO should not 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.
