These investments included the properties in the final closing associated with the Duke Realty healthcare business (“Duke Assets”) and completion of the portfolio acquisition from a Tampa developer, which were announced in Q2 2017. HTA’s investments for the quarter consisted of the following:

◦ Duke Assets: HTA acquired three additional properties in July for an aggregate purchase price of $131.7 million. These properties total approximately 245,000 square feet of GLA and were 100% leased as of the date of acquisition.

2017 Investments - Q3 Performance

• Investments: During 2017, HTA completed and closed $2.7 billion of investments, totaling approximately 6.6 million square feet of GLA, including projects under development.

Approximately 89% of the GLA for these investments are located in HTA’s existing key markets, allowing HTA to manage and service these properties with its existing property management, building services, and leasing platform, thereby generating additional cash flow opportunities.

• Cash NOI: During the quarter, HTA generated $32.9 million of Cash NOI on its 2017 investments, including a partial period impact for acquisitions that closed and developments that were completed during the period. As of September 30, 2017, HTA’s run rate yield on its 2017 investments was approximately 5.1%, which included the full quarter impact of acquisitions and developments closed and completed in the period, and new leases that were signed but not yet occupied.

• Leasing: HTA entered into new leases on approximately 26,000 square feet of GLA for its 2017 investments, or 0.4% of the total acquired GLA.HTA also entered into renewal leases totaling approximately 108,000 square feet of GLA. HTA executed these leases utilizing its existing in-house leasing representatives which would have resulted in capitalized leasing commissions totaling $0.5 million, or 1.5% of third quarter Cash NOI, if third party brokers had been used by HTA.

• Property Management & Building Services: As of the end of the period, HTA provided property management services to 91% of its 2017 investments as measured by GLA. During the quarter, HTA earned over $1.0 million of property management fees related to these properties which were included in total Cash NOI. On an annual basis, these properties generated a total of over $5.0 million in property management fees. As of the end of the period, HTA provided building engineering services to

approximately 64% of the multi-tenanted properties included in its 2017 investments. In addition, during the quarter, HTA earned over $250,000 in expense recoveries from building services which were included in total Cash NOI.

• Development: During the third quarter, HTA-Development completed two development projects located in Oxford, Mississippi and Dallas, TX, with a total construction cost of $33.8 million. As such, four of the seven development properties acquired by HTA as a part of the Duke acquisition have been completed, but are not all fully leased at this time. As of the end of the quarter, these four properties were 77% leased and generated $0.6 million of Cash NOI. HTA is currently in the late stages of lease negotiations for an additional 38,000 square feet of GLA that would bring the leased rate on these properties to 90% if completed. The remaining three properties under development are 100% pre-leased and are projected to be completed by Q2 2018. In total, the seven development properties are projected to generate between $2.50 million and $2.75 million in quarterly Cash NOI upon completion and stabilization.

(1) For the three and nine months ended September 30, 2017, transaction costs have been adjusted to reflect the prospective presentation of the early adoption of ASU 2017-01 as of January 1, 2017. For the nine months ended September 30, 2017, transactions costs included $4.6 million of compensation and severance payments to Duke employees pursuant to the Duke purchase agreements in connection with the Duke acquisition.
(2) Same-Property includes 338 and 296 buildings for the three and nine months ended September 30, 2017 and 2016, respectively.

NOI is a non-GAAP financial measure that is defined as net income or loss (computed in accordance with GAAP) before: (i) general and administrative expenses; (ii) transaction expenses; (iii) depreciation and amortization expense; (iv) impairment; (v) interest expense and net change in fair value of derivative financial instruments; (vi) gain or loss on sales of real estate; (vii) gain or loss on extinguishment of debt; (viii) income or loss from unconsolidated joint venture; and (ix) other income or expense. HTA believes that NOI provides an accurate measure of the operating performance of its operating assets because NOI excludes certain items that are not associated with the management of its properties. Additionally, HTA believes that NOI is a widely accepted measure of comparative operating performance of real estate investment trusts (“REITs”). However, HTA’s use of the term NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. NOI should be reviewed in connection with other GAAP measurements.

Cash NOI is a non-GAAP financial measure which excludes from NOI: (i) straight-line rent adjustments and (ii) amortization of below and above market leases/leasehold interests. Contractual base rent, contractual rent increases, contractual rent concessions and changes in occupancy or lease rates upon commencement and expiration of leases are a primary driver of HTA’s revenue performance. HTA believes that Cash NOI, which removes the impact of straight-line rent adjustments, provides another measurement of the operating performance of its operating assets. Additionally, HTA believes that Cash NOI is a widely accepted measure of comparative operating performance of REITs. However, HTA’s use of the term Cash NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Cash NOI should be reviewed in connection with other GAAP measurements.

To facilitate the comparison of Cash NOI between periods, HTA calculates comparable amounts for a subset of its owned properties referred to as “Same-Property”. Same-Property Cash NOI excludes properties which have not been owned and operated by HTA during the entire span of all periods presented, excluding properties intended for disposition in the near term, notes receivable interest income and certain non-routine items. Same-Property Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Same-Property Cash NOI should be reviewed in connection with other GAAP measurements.

(2) For the nine months ended September 30, 2017, other normalizing items include $4.6 million of compensation and severance payments to Duke employees pursuant to the Duke purchase agreements in connection with the Duke acquisition that were included in transaction expenses on HTA’s condensed consolidated statements of operations. In addition, other normalizing items excludes lease termination fees as they are deemed to be generated in the ordinary course of business.

HTA computes FFO in accordance with the current standards established by NAREIT. NAREIT defines FFO as net income or loss attributable to common stockholders (computed in accordance with GAAP), excluding gains or losses from sales of real estate property and impairment write-downs of depreciable assets, plus depreciation and amortization related to investments in real estate, and after adjustments for unconsolidated partnerships and joint ventures. HTA presents this non-GAAP financial measure because it considers it an important supplemental measure of its operating performance and believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Historical cost accounting assumes that the value of real estate assets diminishes ratably over time. Since real estate values have historically risen or fallen based on market conditions, many industry investors have considered the presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Because FFO excludes depreciation and amortization unique to real estate, among other items, it provides a perspective not immediately apparent from net income or loss attributable to common stockholders.

HTA computes Normalized FFO, which excludes from FFO: (i) transaction expenses; (ii) gain or loss on change in fair value of derivative financial instruments; (iii) gain or loss on extinguishment of debt; (iv) noncontrolling income or loss from partnership units included in diluted shares; and (v) other normalizing items, which include items that are unusual and infrequent in nature. HTA presents this non-GAAP financial measure because it allows for the comparison of our operating performance to other REITs and between periods on a consistent basis. HTA’s methodology for calculating Normalized FFO may be different from the methods utilized by other REITs and, accordingly, may not be comparable to other REITs. Normalized FFO should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FFO should be reviewed in connection with other GAAP measurements.

HTA also computes Normalized FAD, which excludes from Normalized FFO: (i) other income or expense; (ii) non-cash compensation expense; (iii) straight-line rent adjustments; (iv) amortization of below and above market leases/leasehold interests and corporate assets; (v) amortization of deferred financing costs and debt premium/discount; and (vi) recurring capital expenditures, tenant improvements and leasing commissions. HTA believes this non-GAAP financial measure provides a meaningful supplemental measure of our operating performance. Normalized FAD should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FAD should be reviewed in connection with other GAAP measurements.

Portfolio • Investments: During the quarter, HTA had investments of $160.7 million, totaling approximately 314,000 square feet of GLA and which were 99% leased as of the date of acquisition, bringing year-to-date investments to $2.7 billion, net of development credits received at the closing of the Duke acquisition. These investments included the properties in the final closing associated with the Duke Realty healthcare business (“Duke Assets”) and completion of the portfolio acquisition from a Tampa developer, which were announced in Q2 2017. HTA’s investments for the quarter consisted of the following: ◦ Duke Assets: HTA acquired three additional properties in July for an aggregate purchase price of $131.7 million. These properties total approximately 245,000 square feet of GLA and were 100% leased as of the date of acquisition. ◦ Tampa Developer: HTA acquired two additional properties in July and August for an aggregate purchase price of $29.0 million.

As of September 30, 2017, HTA’s run rate yield on its 2017 investments was approximately 5.1%, which included the full quarter impact of acquisitions and developments closed and completed in the period, and new leases that were signed but not yet occupied. • Leasing: HTA entered into new leases on approximately 26,000 square feet of GLA for its 2017 investments, or 0.4% of the total acquired GLA. HTA also entered into renewal leases totaling approximately 108,000 square feet of GLA. HTA executed these leases utilizing its existing in-house leasing representatives which would have resulted in capitalized leasing commissions totaling $0.5 million, or 1.5% of third quarter Cash NOI, if third party brokers had been used by HTA. • Property Management & Building Services: As of the end of the period, HTA provided property management services to 91% of its 2017 investments as measured by GLA. During the quarter, HTA earned over $1.0 million of property management fees related to these properties which were included in total Cash NOI. On an annual basis, these properties generated a total of over $5.0 million in property management fees. As of the end of the period, HTA provided building engineering services to approximately 64% of the multi-tenanted properties included in its 2017 investments. In addition, during the quarter, HTA earned over $250,000 in expense recoveries from building services which were included in total Cash NOI. • Development: During the third quarter, HTA-Development completed two development projects located in Oxford, Mississippi and Dallas, TX, with a total construction cost of $33.8 million. As such, four of the seven development properties acquired by HTA as a part of the Duke acquisition have been completed, but are not all fully leased at this time. As of the end of the quarter, these four properties were 77% leased and generated $0.6 million of Cash NOI. HTA is currently in the late stages of lease negotiations for an additional 38,000 square feet of GLA that would bring the leased rate on these properties to 90% if completed. The remaining three properties under development are 100% pre-leased and are projected to be completed by Q2 2018. In total, the seven development properties are projected to generate between $2.50 million and $2.75 million in quarterly Cash NOI upon completion and stabilization. Capital Markets • Equity: In September 2017, HTA entered into new equity distribution agreements with its various sales agents with respect to its at-the- market (“ATM”) offering program of common stock with an aggregate sales amount of up to $500.0 million. • Debt: In July 2017, HTA, as guarantor, and Healthcare Trust of America Holdings, LP (“HTALP”), as borrower, entered into an amended and restated $1.3 billion unsecured credit agreement which increased the amount available under the unsecured revolving credit facility to $1.0 billion and extended the maturities of the unsecured revolving credit facility to June 30, 2022 and for the $300.0 million unsecured term loan until February 1, 2023. The interest rate on the unsecured revolving credit facility is adjusted LIBOR plus a margin ranging from 0.83% to 1.55% per annum based on HTA’s credit rating.

Year-to-Date 2017 Highlights Operating • Net Income Attributable to Common Stockholders: Decreased 27.1% to $21.4 million, compared to year-to-date 2016. Earnings per diluted share decreased 42.9% to $0.12 per diluted share, compared to year-to-date 2016. Total revenues increased $101.3 million due to the continued growth in HTA’s operations, however, the increase in revenues was primarily offset as a result of the Duke acquisition by the increase in transaction expenses and loss on extinguishment of debt related to bridge facility fees paid. • FFO: As defined by NAREIT, increased 28.5%, to $198.7 million, compared to year-to-date 2016. FFO per diluted share remained stable at $1.12 per diluted share, compared to year-to-date 2016. • Normalized FFO: Increased 29.9%, to $215.2 million, compared to year-to-date 2016.

HTA’s only remaining obligations related to the Duke acquisition are the potential acquisition of a land parcel in Miami, FL and a single property in Texas that are each currently excluded from HTA’s purchase obligations due to current outstanding physical condition issues. ◦ In addition, HTA completed investments of $458.3 million, totaling approximately 1.5 million square feet of GLA that were 93% leased as of the date of acquisition and which were located substantially in certain of HTA’s 20 to 25 key markets. • Development Platform Acquisition: During the nine months ended September 30, 2017, HTA completed its acquisition of Duke’s development and construction platform as part of the Duke acquisition. Prior to HTA’s acquisition, this best-in-class development platform, renamed HTA-Development by HTA, had developed over $1.0 billion in medical real estate assets over the last 10 years. • Dispositions: HTA completed the disposition of a medical office building located in Texas for a gross sales price of $5.0 million and which totaled approximately 48,000 square feet of GLA. • Leasing: HTA entered into new and renewal leases on approximately 2.0 million square feet of GLA, or 8.4%, of its portfolio. Tenant retention for the Same-Property portfolio was 78% by GLA year-to-date, which included approximately 1.3 million square feet of expiring leases. Renewal leases included tenant improvements of $1.51 per square foot of GLA per year of the lease term and less than five days of free rent per year of the lease term. • Leased Rate: As of September 30, 2017, HTA had a leased rate for its portfolio of 91.7% by GLA and 91.4% for its Same-Property portfolio. Balance Sheet and Capital Markets • Balance Sheet: As of September 30, 2017, HTA had total leverage of 31.9% measured as debt to total capitalization, and 6.2x measured as debt to Adjusted Earnings before Interest, Taxes, Depreciation and Amortization for real estate (“Adjusted EBITDAre”).

HTA also executed, as borrower, a $286.0 million promissory note with a 4.0% per annum interest rate with the seller in the Duke acquisition. Additionally, in July 2017, HTA, as guarantor, and HTALP, as borrower, entered into an amended and restated $1.3 billion unsecured credit agreement which increased the amount available under the unsecured revolving credit facility to $1.0 billion and extended the maturity date to June 30, 2022, and extended the maturity date until February 1, 2023 under the $300.0 million unsecured term loan. These transactions were used to substantially finance HTA’s 2017 investments and position its investment grade balance sheet for future growth. Subsequent Events • Investments: In October 2017, HTA completed an investment with a purchase price of $8.3 million. As part of the acquisition, HTA issued to the seller as a part of the acquisition consideration a total of 16,972 operating partnership units in HTALP with a market value at the time of issuance of $0.5 million. • Equity: Subsequent to September 30, 2017, HTA issued approximately $200.0 million of common stock under the ATM, including $75.0 million on a forward basis which will be issued over the next six months. • Dividends: On October 24, 2017, HTA’s Board of Directors announced a quarterly dividend of $0.305 per share of common stock.

3Q 2017 I Supplemental Information Healthcare Trust of America, Inc. I 23 Reporting Definitions Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (“Adjusted EBITDAre”): As previously defined as Adjusted EBITDA, Adjusted EBITDAre is presented on an assumed annualized basis. HTA defines Adjusted EBITDAre as EBITDAre (computed in accordance with NAREIT as defined below) plus: (i) transaction expenses; (ii) gain or loss on extinguishment of debt; (iii) non-cash compensation expense; (iv) pro forma impact of our acquisitions/dispositions; and (v) other normalizing items. HTA consider Adjusted EBITDAre an important measure because it provides additional information to allow management, investors, and our current and potential creditors to evaluate and compare our core operating results and our ability to service debt. Annualized Base Rent: Annualized base rent is calculated by multiplying contractual base rent for the end of the period by 12 (excluding the impact of abatements, concessions, and straight-line rent).  Cash Net Operating Income (“Cash NOI”): Cash NOI is a non-GAAP financial measure which excludes from NOI: (i) straight-line rent adjustments and (ii) amortization of below and above market leases/leasehold interests. Contractual base rent, contractual rent increases, contractual rent concessions and changes in occupancy or lease rates upon commencement and expiration of leases are a primary driver of HTA’s revenue performance. HTA believes that Cash NOI, which removes the impact of straight-line rent adjustments, provides another measurement of the operating performance of its operating assets. Additionally, HTA believes that Cash NOI is a widely accepted measure of comparative operating performance of real estate investment trusts (“REITs”). However, HTA’s use of the term Cash NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Cash NOI should be reviewed in connection with other GAAP measurements. Credit Ratings: Credit ratings of our tenants or their parent companies. Customary Health System Restrictions: Ground leases with a health system lessor that include restrictions on tenants that may be considered competitive with the hospital, which may include provisions that tenants must have hospital privileges. Economic with Limited Restrictions: Ground leases that are primarily economic in nature and contain no material restrictions on tenancy. Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (“EBITDAre”): In September 2017, NAREIT issued a white paper defining EBITDA for real estate which HTA effectively adopted as of September 30, 2017. NAREIT defines EBITDAre as net income or loss (computed in accordance with GAAP) plus: (i) interest expense and net change in the fair value of derivative financial instruments; (ii) income tax expense (not applicable to HTA); (iii) depreciation and amortization; (iv) impairment; (v) gain or loss from sale of real estate; and (vi) and proportionate share of joint venture depreciation, amortization and other adjustments. Funds from Operations (“FFO”): HTA computes FFO in accordance with the current standards established by NAREIT. NAREIT defines FFO as net income or loss attributable to common stockholders (computed in accordance with GAAP), excluding gains or losses from sales of real estate property and impairment write-downs of depreciable assets, plus depreciation and amortization related to investments in real estate, and after adjustments for unconsolidated partnerships and joint ventures. HTA presents this non-GAAP financial measure because it considers it an important supplemental measure of its operating performance and believes it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Historical cost accounting assumes that the value of real estate assets diminishes ratably over time. Since real estate values have historically risen or fallen based on market conditions, many industry investors have considered the presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Because FFO excludes depreciation and amortization unique to real estate, among other items, it provides a perspective not immediately apparent from net income or loss attributable to common stockholders. Gross Leasable Area (“GLA”): Gross leasable area (in square feet). Investments in Real Estate: Based on acquisition price. Leased Rate: Leased rate represents the percentage of total GLA that is leased (excluding GLA for properties under development), including month-to-month leases and leases which have been executed, but which have not yet commenced, as of the date reported. Metropolitan Statistical Area (“MSA”): Is a geographical region with a relatively high population density at its core and close economic ties throughout the area. MSAs are defined by the Office of Management and Budget. Net Operating Income (“NOI”): NOI is a non-GAAP financial measure that is defined as net income or loss (computed in accordance with GAAP) before: (i) general and administrative expenses; (ii) transaction expenses; (iii) depreciation and amortization expense; (iv) impairment; (v) interest expense and net change in fair value of derivative financial instruments; (vi) gain or loss on sales of real estate; (vii) gain or loss on extinguishment of debt; (viii) income or loss from unconsolidated joint venture; and (ix) other income or expense. HTA believes that NOI provides an accurate measure of the operating performance of its operating assets because NOI excludes certain items that are not associated with the management of its properties. Additionally, HTA believes that NOI is a widely accepted measure of comparative operating performance of REITs. However, HTA’s use of the term NOI may not be comparable to that of other REITs as they may have different methodologies for computing this amount. NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. NOI should be reviewed in connection with other GAAP measurements.

3Q 2017 I Supplemental Information Healthcare Trust of America, Inc. I 24 Reporting Definitions - Continued Normalized Funds Available for Distribution (“Normalized FAD”): HTA computes Normalized FAD, which excludes from Normalized FFO: (i) other income or expense; (ii) non-cash compensation expense; (iii) straight-line rent adjustments; (iv) amortization of below and above market leases/leasehold interests and corporate assets; (v) amortization of deferred financing costs and debt premium/discount; and (vi) recurring capital expenditures, tenant improvements and leasing commissions. HTA believes this non-GAAP financial measure provides a meaningful supplemental measure of our operating performance. Normalized FAD should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FAD should be reviewed in connection with other GAAP measurements. Normalized Funds From Operations (“Normalized FFO”): HTA computes Normalized FFO, which excludes from FFO: (i) transaction expenses; (ii) gain or loss on change in fair value of derivative financial instruments; (iii) gain or loss on extinguishment of debt; (iv) noncontrolling income or loss from partnership units included in diluted shares; and (v) other normalizing items, which include items that are unusual and infrequent in nature. HTA presents this non-GAAP financial measure because it allows for the comparison of our operating performance to other REITs and between periods on a consistent basis. HTA’s methodology for calculating Normalized FFO may be different from the methods utilized by other REITs and, accordingly, may not be comparable to other REITs. Normalized FFO should not be considered as an alternative to net income or loss attributable to common stockholders (computed in accordance with GAAP) as an indicator of our financial performance, nor is it indicative of cash available to fund cash needs. Normalized FFO should be reviewed in connection with other GAAP measurements. Occupancy Health System Restrictions: Ground leases with customary health system restrictions whereby the restrictions cease if occupancy in the buildings/on-campus fall below stabilized occupancy, which is generally between 85% and 90%. Off-Campus/Non-Aligned: A building or portfolio that is not located on or adjacent to a healthcare or hospital campus or does not have a majority alignment with a recognized healthcare system. On-Campus/Aligned: On-campus refers to a property that is located on or adjacent to a healthcare or hospital campus. Aligned refers to a property that is not on a healthcare or hospital campus, but anchored by a healthcare system. Recurring Capital Expenditures, Tenant Improvements and Leasing Commissions: Represents amounts paid for: (i) recurring capital expenditures required to maintain and re-tenant our properties; (ii) second generation tenant improvements; and (iii) leasing commissions paid to secure new tenants. Excludes capital expenditures and tenant improvements for recent acquisitions that were contemplated in the purchase price or closing agreements. Retention:  Represents the sum of the total leased GLA of tenants that renewed a lease during the period over the total GLA of leases that renewed or expired during the period. Same-Property Cash Net Operating Income (“Same-Property Cash NOI”): To facilitate the comparison of Cash NOI between periods, HTA calculates comparable amounts for a subset of its owned properties referred to as “Same-Property”. Same-Property Cash NOI excludes properties which have not been owned and operated by HTA during the entire span of all periods presented, excluding properties intended for disposition in the near term, notes receivable interest income and certain non-routine items. Same-Property Cash NOI should not be considered as an alternative to net income or loss (computed in accordance with GAAP) as an indicator of our financial performance. Same-Property Cash NOI should be reviewed in connection with other GAAP measurements.
