Company Overview Portfolio - Cont. • Investments: During the six months ended June 30, 2018, HTA invested $8.4 million to acquire an MOB of approximately 24,000 square feet of GLA in Raleigh, North Carolina, that was 100% leased as of the acquisition date to Duke Health System. In addition, HTA invested $3.9 million to consolidate its ownership interests in several other MOBs. • Dispositions: Subsequent to June 30, 2018, HTA entered into agreements to sell its Greenville, South Carolina MOB portfolio for a total of $294.3 million in two transactions, including the sale of a single MOB for $9.3 million that has closed subsequent to June 30, 2018 which was classified as held for sale as of June 30, 2018. The remaining properties are expected to close in August 2018. HTA has additional properties under contract to sell which would total up to an additional $60 million of gross proceeds. These properties are subject to customary closing conditions and no closings are assured. HTA intends to use the net proceeds to pay down debt, repurchase shares of its common stock, to invest in acquisitions and developments in markets where it believes it can utilize its property management and leasing platform to drive incremental returns, and for general corporate purposes. 2017 Investment Performance • Cash NOI: During the three months ended June 30, 2018, HTA generated $34.8 million of Cash NOI on its 2017 investments, including its investment in its unconsolidated joint venture. This Cash NOI includes over $2.2 million of income from property management and building engineering services provided to its tenants. As of June 30, 2018, HTA’s run rate yield on its 2017 investments was approximately 5.3%, which included the full year impact of new leases which have been executed, but which have not yet commenced. • Development: As of part the 2017 investments, HTA acquired seven development projects that were under construction and not stabilized at the date of acquisition. Prior to this quarter, HTA had completed five of the seven development projects. During the period ended June 30, 2018, HTA completed the development MOB of Memorial Hermann in Houston, Texas. This MOB was 100,000 square feet of GLA and 100% pre-leased to the hospital. The remaining development has been completed in July 2018. As of June 30, 2018, the six completed development properties were 87% leased and generated $1.9 million of Cash NOI. HTA believes it is currently in the late stages of lease negotiations for an additional 33,000 square feet of GLA that would bring the leased rate on these development properties to 88%, if completed. In total, the seven development properties are projected to generate between approximately $2.5 million and $2.8 million in quarterly Cash NOI upon completion and stabilization. Balance Sheet and Capital Markets • Balance Sheet: As of June 30, 2018, HTA had total leverage of 31.8% measured as debt less cash and cash equivalents to total capitalization, and 5.8x measured as debt less cash and cash equivalents to Adjusted Earnings before Interest, Taxes, Depreciation and Amortization for real estate (“Adjusted EBITDAre”). Total liquidity at the end of the quarter was $1.0 billion, including $994.5 million of availability under HTA’s unsecured revolving credit facility and $26.2 million of cash and cash equivalents. • Debt: During the three months ended June 30, 2018, HTA paid down $96.0 million on its $286.0 million promissory note to the seller, as lender, in the Duke acquisition. The interest rate on the promissory note is 4% per annum. • Equity: In June 2018, HTA settled its forward sale arrangement pursuant to its forward equity agreement, which included approximately 2.6 million shares of its common stock for net proceeds of approximately $73.8 million, adjusted for costs to borrow equating to a net price to HTA of $28.94 per share of common stock. • Share Repurchase Plan: On June 8, 2018, HTA’s Board of Directors approved a stock repurchase plan authorizing HTA to purchase up to $100 million of its common stock from time to time prior to the expiration thereof on June 7, 2020. During June 2018, pursuant to this plan, HTA repurchased 333,002 shares of its common stock, at an average price of $26.26 per share, for an aggregate amount of $8.7 million. In August 2018, HTA’s Board of Directors terminated the foregoing plan and adopted a new plan with an increased share repurchase authorization of up to $300 million. Subsequent Events • Debt: Subsequent to June 30, 2018, HTA’s operating partnership, HTALP, entered into a modification of its $200.0 million unsecured term loan due in 2023. This modification decreased pricing at HTA’s current credit rating by 65 bps from LIBOR plus 165 bps to LIBOR plus 100 bps. The maturity date was also extended by five months to January 2024. The other material terms of the unsecured term loan prior to the modification remained substantially unchanged. • Dividends: On August 2, 2018, HTA’s Board of Directors announced an increased quarterly dividend of $0.310 per share of common stock and per OP Unit. The quarterly dividend is to be paid on October 5, 2018 to stockholders of record of its common stock and holders of its OP Units on October 2, 2018. 2Q 2018 I Supplemental Information Healthcare Trust of America, Inc.

Reporting Definitions Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (“Adjusted EBITDAre”): 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 its acquisitions/dispositions; and (v) other normalizing items. HTA considers Adjusted EBITDAre an important measure because it provides additional information to allow management, investors, and its current and potential creditors to evaluate and compare its core operating results and its 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; (ii) amortization of below and above market leases/leasehold interests; (iii) notes receivable interest income; and (iv) other GAAP adjustments. 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 its financial performance. Cash NOI should be reviewed in connection with other GAAP measurements. Credit Ratings: Credit ratings of HTA’s tenants or their parent companies. Customary Health System Restrictions: Ground leases with a health system ground lessor that include restrictions on tenants that may be considered competitive with the hospital, including 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”): 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 its financial performance. NOI should be reviewed in connection with other GAAP measurements. 2Q 2018 I Supplemental Information Healthcare Trust of America, Inc. I 23

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 its 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 its 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 its 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 its 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 full 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 is 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 its 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 and operational properties referred to as “Same-Property”. Same-Property Cash NOI excludes (i) properties which have not been owned and operated by HTA during the entire span of all periods presented and disposed properties, (ii) HTA’s share of unconsolidated joint ventures, (iii) development, redevelopment and land parcels, (iv) properties intended for disposition in the near term which have (a) been approved by the Board of Directors, (b) is actively marketed for sale, and (c) an offer has been received at prices HTA would transact and the sales process is ongoing, and (v) 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 its financial performance. Same-Property Cash NOI should be reviewed in connection with other GAAP measurements. Tenant Recoveries: Tenant reimbursement revenue, which is comprised of additional amounts recoverable from tenants for real estate taxes, common area maintenance and other certain operating expenses are recognized as revenue on a gross basis in the period in which the related recoverable expenses are incurred.  HTA accrues revenue corresponding to these expenses on a quarterly basis to adjust recorded amounts to its best estimate of the final annual amounts to be billed. Subsequent to year-end, on a calendar year basis, HTA performs reconciliations on a lease-by-lease basis and bill or credit each tenant for any differences between the estimated expenses HTA billed and the actual expenses that were incurred. 2Q 2018 I Supplemental Information Healthcare Trust of America, Inc.
