Re-leasing spreads increased to 4.7% and tenant retention for the Same-Property portfolio was 85% by GLA year-to-date. Balance Sheet and Capital Markets • Balance Sheet: HTA ended Q2 2019 with total liquidity of $1.0 billion, inclusive of $23.2 million of cash and cash equivalents, and a $52.1 million forward equity agreement, resulting in total leverage of (i) 30.7%, measured as debt less cash and cash equivalents to total capitalization, and (ii) 5.7x, measured as debt less cash and cash equivalents to Adjusted Earnings before Interest, Taxes, Depreciation and Amortization for real estate (“Adjusted EBITDAre”). • Equity: In June 2019, under its at-the-market (“ATM”) offering program, HTA entered into a forward sale arrangement in which it would issue approximately 1.8 million shares of common stock to receive anticipated net proceeds of approximately $52.1 million prior to June 2020, subject to adjustments as provided in the forward equity agreement. Noteworthy 2019 Activities • Investments: To date, HTA has closed on approximately $111 million of investments totaling approximately 320,000 square feet of GLA with $74.1 million closed during Q2 2019 and $18.0 million closed subsequent to Q2 2019. These investments are primarily located in HTA’s existing key markets and acquired at average capitalization rates of 5.5%. The key acquisitions are highlighted by the following: ◦ Streeterville Center: An on-campus MOB located adjacent to Northwestern Memorial Hospital, in downtown Chicago, IL. We acquired the 72,000 square foot MOB for $40.0 million. It is approximately 98% leased and will be operated by HTA’s internal asset management platform. ◦ Charlotte MOBs: Two MOBs located in affluent Charlotte, NC suburbs for $20.3 million totaling 73,000 square feet of GLA. These include an MOB adjacent to Novant Huntersville hospital campus and a core community MOB in close proximity to Davidson College. With these acquisitions, HTA’s Charlotte, NC presence will increase to over 400,000 square feet of GLA, allowing HTA to bring its assets onto its internal asset management platform allowing HTA to expand its key health system relationships. ◦ Fairfax MOB: An MOB investment of $18.0 million closed subsequent to Q2 2019, totaling approximately 57,000 square feet of GLA and approximately 98% leased. 2Q 2019 I Supplemental Information Healthcare Trust of America, Inc.

Company Overview Noteworthy 2019 Activities - Continued • Dividends: On July 23, 2019, HTA’s Board of Directors announced an increased quarterly cash dividend of $0.315 per share of common stock and per OP Unit. The quarterly dividend is to be paid on October 10, 2019 to stockholders of record of its common stock and holders of its OP Units on October 3, 2019. Impact of Topic 842 Leases • The Financial Accounting Standards Board issued Topic 842, which was effective for HTA as of January 1, 2019. Topic 842 modifies the treatment of initial direct costs, which historically under Topic 840 were capitalized in accordance with certain criteria provided for in the applicable guidance. Topic 842 also eliminates the accounting recognition of expenses paid directly by tenants and moves certain bad debt costs from expense to revenue. During the three and six months ended Q2 2018, HTA capitalized $0.9 million and $2.2 million, respectively, of initial direct costs that would now be expensed under Topic 842. In addition, for the three and six months ended Q2 2018, HTA recognized $3.4 million and $7.0 million, respectively, of tenant paid property taxes in both revenues and expenses and a nominal amount of bad debt costs recognized as expenses. 2019 Guidance For 2019, HTA updated its earnings guidance as follows: Annual Expectations Low to High Net income attributable to common stockholders per share $0.33 $0.36 Same-Property Cash NOI 2.0% 3.0% FFO per share, as defined by NAREIT $1.62 $1.64 Normalized FFO per share $1.63 $1.65 2Q 2019 I Supplemental Information Healthcare Trust of America, Inc.

Reporting Definitions Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (“Adjusted EBITDAre”): 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 and other GAAP adjustments; and (iii) notes receivable interest income. 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 parent tenants and their subsidiaries. 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”): As defined by NAREIT, EBITDAre is computed as net income or loss (computed in accordance with GAAP) plus: (i) interest expense; (ii) income tax expense (not applicable to HTA); (iii) depreciation and amortization; (iv) impairment; (v) gain or loss on the sale of real estate; and (vi) and the proportionate share of joint venture depreciation and amortization. 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 HTA’s financial performance. NOI should be reviewed in connection with other GAAP measurements. 2Q 2019 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) non-cash compensation expense; (ii) straight-line rent adjustments; (iii) amortization of below and above market leases/leasehold interests and corporate assets; (iv) deferred revenue - tenant improvement related and other income; (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 extinguishment of debt; (iii) noncontrolling income or loss from partnership units included in diluted shares; and (iv) 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) are 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 2019 I Supplemental Information Healthcare Trust of America, Inc.
