Earnings Release 4 NETSTREIT REPORTS THIRD QUARTER 2021 FINANCIAL AND OPERATING RESULTS – Completed $94.3 Million of Gross Investment Activity – – $18.8 Million of Dispositions Further Strengthens Portfolio Foundation – – $90.9 Million of Net Acquisitions Completed Subsequent to Quarter End, Resulting in Increased 2021 Net Acquisition Guidance – Dallas TX – October 28, 2021 – NETSTREIT (NYSE: NTST) (the “Company”), today announced financial and operating results for the third quarter ended September 30, 2021. THIRD QUARTER 2021 HIGHLIGHTS • Reported net income per share of $0.07, Core Funds from Operations (“Core FFO”) per share of $0.221 and AFFO per share of $0.241 (see non-GAAP reconciliation attached) PORTFOLIO UPDATE As of September 30, 2021, the NETSTREIT portfolio was comprised of 290 leases2, contributing $59.8 million of annualized base rent3, with a weighted-average remaining lease term of 10.0 years, of which 70.5% were with investment grade rated tenants and 14.5% were with tenants with investment grade profiles4. The portfolio was 100.0% occupied as of September 30, 2021. INVESTMENT ACTIVITY During the quarter ended September 30, 2021, the Company acquired 26 properties for approximately $90.1 million at an initial cash capitalization rate of 6.2%, inclusive of closing costs. A majority of these acquisitions closed late in the third quarter, resulting in the Company owning the assets for an average of approximately seven days during the quarter. Acquisitions completed during the quarter had a weighted-average remaining lease term of 12.4 years, and 74.8% of the properties were occupied by investment grade rated tenants with an additional 15.0% occupied by tenants with investment grade profiles. During the third quarter, the Company also provided $4.2 million of development funding, including funding to support a new development for an investment grade profile tenant and a future build-to-suit development. The Company completed four strategic dispositions in the third quarter for $18.8 million in total contractual sales proceeds, which equated to a 6.3% cash capitalization rate. The dispositions provided diversification benefits, reducing the Company's exposure to casual dining and banking, to 0.9% and 0.7%, respectively, and also allowed the Company to capitalize on the improved outlook for a cyclical RV sales tenant category. The Company's net investment activity for the third quarter was $75.5 million. The transaction activity increased total tenant count from 59 to 60 tenants, adding Five Below (investment grade profile), OSF Urgent Care (A / A3), and DaVita (BB / Ba2) to the tenant roster. Additionally, the transaction activity increased the portfolio's geographic diversity to 40 states.

Earnings Release 5 Subsequent to quarter end, the Company completed twelve acquisitions for $90.9 million, including closing costs. “We are pleased with our performance this quarter and for the month of October, as we executed on $181.0 million of acquisitions to grow our ABR with high quality tenants and further diversify our tenant roster and industry mix. While the timing of transaction closings and higher than anticipated dispositions negatively impacted earnings for the quarter, leading to revised AFFO per share guidance, our primary focus remains on purposely improving the size and quality of our portfolio to generate sustainable growth in earnings and dividends, as demonstrated by our high quality credit metrics and increased investment guidance," said Mark Manheimer, Chief Executive Officer of NETSTREIT. BALANCE SHEET AND LIQUIDITY In September, the Company filed an automatically effective shelf registration with the Securities Exchange Commission and implemented an at-the-market ("ATM") offering program allowing the Company to issue and sell shares of its common stock in an aggregate amount of up to $250 million. The Company sold no shares through the ATM offering during the third quarter. At quarter end, total debt outstanding was $192 million, with a weighted average term of 3.1 years and a quarter end contractual interest rate, including the impact of the fixed rate swap, of 1.35% (excluding the impact of deferred fee amortization). The Company’s net debt to annualized adjusted EBITDA ratio was 3.5x, and the ending cash balance was $28 million. DIVIDEND On October 26, 2021, the Company’s Board of Directors declared a quarterly cash dividend of $0.20 per share for the fourth quarter of 2021, which will be paid on December 15, 2021 to shareholders of record on December 1, 2021. 2021 OUTLOOK The Company is revising its full year 2021 AFFO per share guidance in the range of $0.93 to $0.95 per share, primarily as a result of higher than anticipated disposition activity, as well as acquisition timing, in the third quarter. This AFFO guidance is based on the following assumptions: • For full year 2021, the Company is increasing its net acquisition activity, inclusive of dispositions, to be at least $400 million • The Company expects cash G&A to be at the top end of the previously provided range of $11.0 to $12.0 million, which includes recurring transaction costs, and expects non-cash compensation expense to be at the midpoint of the previously provided range of $3.0 to $4.0 million • The Company expects cash interest expense, including unused line of credit facility fees, to be at the lower end of the previously provided range of $3.0 to $3.5 million, with no change to the previously provided $0.6 million of additional non-cash deferred financing fee amortization

Earnings Release 6 • The Company expects taxes to be at the top end of the previously provided range of $0.2 to $0.3 million • Full year 2021 diluted weighted average shares outstanding, which includes the impact of OP units, are expected to be in the range of 38 to 39 million shares The Company does not provide guidance for net income (loss) per share, the most directly comparable GAAP measure to AFFO per share, and similarly cannot provide a reconciliation between its forecasted AFFO per share and the comparable GAAP measure without unreasonable effort due to the unavailability of reliable estimates for certain items. These items are not within the Company's control and may vary greatly between periods and could significantly impact future financial results.

Non-GAAP Measures and Definitions 21 FFO, Core FFO, and AFFO FFO means funds from operations. It is a non-GAAP measure defined by NAREIT as net income (computed in accordance with GAAP), excluding real estate-related expenses including, but not limited to, gains (losses) from sales, impairment adjustments, and depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Our calculation of FFO is consistent with FFO as defined by NAREIT. Core FFO means core funds from operations. It is a non-GAAP financial measure defined as FFO adjusted for gains from forfeited earnest money deposits and non-recurring 144A and IPO transaction costs. We believe the presentation of Core FFO provides investors with a metric to assist in their evaluation of our operating performance across multiple periods because it removes the effect of unusual and non-recurring items that are not expected to impact our operating performance on an ongoing basis. AFFO means adjusted funds from operations. It is a non-GAAP financial measure defined as Core FFO adjusted for GAAP net income related to non-cash revenues and expenses, such as straight-line rental revenue, amortization of above and below-market lease-related intangibles, amortization of lease incentives, capitalized interest expense, non-cash compensation expense, and amortization of deferred financing costs. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. In fact, real estate values historically have risen or fallen with market conditions. FFO is intended to be a standard supplemental measure of operating performance that excludes historical cost depreciation and valuation adjustments from net income. We consider FFO to be useful in evaluating potential property acquisitions and measuring operating performance. We further consider FFO, Core FFO and AFFO to be useful in determining funds available for payment of distributions. FFO, Core FFO and AFFO do not represent net income or cash flows from operations as defined by GAAP. You should not consider FFO, Core FFO and AFFO to be alternatives to net income as a reliable measure of our operating performance; nor should you consider FFO, Core FFO and AFFO to be alternatives to cash flows from operating, investing or financing activities (as defined by GAAP) as measures of liquidity. FFO, Core FFO and AFFO do not measure whether cash flow is sufficient to fund our cash needs, including principal amortization, capital improvements and distributions to stockholders. FFO, Core FFO and AFFO do not represent cash flows from operating, investing or financing activities as defined by GAAP. Further, FFO, Core FFO and AFFO as disclosed by other REITs might not be comparable to our calculations of FFO, Core FFO and AFFO.

Non-GAAP Measures and Definitions (cont’d) 22 EBITDA, EBITDAre and Adjusted EBITDAre EBITDA is computed by us as earnings before interest, income taxes and depreciation and amortization. EBITDAre is the NAREIT definition of EBITDA (as defined above), but it is further adjusted to follow the definition included in a white paper issued in 2017 by NAREIT, which recommended that companies that report EBITDA also report EBITDAre. We compute EBITDAre in accordance with the definition adopted by NAREIT. NAREIT defines EBITDAre as EBITDA (as defined above) excluding gains (or losses) from the sales of depreciable property and real estate impairment losses. Adjusted EBITDAre, as computed by us, is EBITDAre adjusted to exclude straight-line rental revenue, gains from forfeited earnest money deposits, non-recurring 144A and IPO transaction costs, and non-cash compensation expense. Annualized Adjusted EBITDAre is Adjusted EBITDAre multiplied by four. We present EBITDA, EBITDAre and Adjusted EBITDAre as they are measures commonly used in our industry. We believe that these measures are useful to investors and analysts because they provide supplemental information concerning our operating performance, exclusive of certain non-cash items and other costs. We use EBITDA and EBITDAre as measures of our operating performance and not as measures of liquidity. EBITDA, EBITDAre and Adjusted EBITDAre do not include all items of revenue and expense included in net income, they do not represent cash generated from operating activities and they are not necessarily indicative of cash available to fund cash requirements; accordingly, they should not be considered alternatives to net income as a performance measure or cash flows from operations as a liquidity measure and should be considered in addition to, and not in lieu of, GAAP financial measures. Additionally, our computation of EBITDA and EBITDAre may differ from the methodology for calculating these metrics used by other equity REITs and, therefore, may not be comparable to similarly titled measures reported by other equity REITs. NOI, Cash NOI, and Normalized Cash NOI NOI means net operating income, and it is computed in accordance with GAAP. It is calculated by subtracting property operating expenses from rental revenue including reimbursements (as presented on the Statement of Operations). Cash NOI is computed by us as GAAP NOI excluding straight-line rental revenue and amortization of above/below-market leases intangibles and lease incentives. Normalized Cash NOI is computed by us as Cash NOI adjusted to remove Cash NOI for properties acquired during the period shown, and then replace the removed amount with an estimated equivalent ABR for the full period. It is further adjusted to remove Cash NOI for properties disposed of during the period shown.

Non-GAAP Measures and Definitions (cont’d) 23 Other Definitions ABR means annualized base rent. ABR is calculated by multiplying (i) cash rental payments (a) for the month ended September 30, 2021 (or, if applicable, the next full month’s cash rent contractually due in the case of rent abatements, rent deferrals, recently acquired properties and properties with contractual rent increases, other than properties under development) for leases in place as of September 30, 2021, plus (b) for properties under development, the first full month’s permanent cash rent contractually due after the development period by (ii) 12. Defensive Category is considered by us to represent tenants that focus on necessity goods and essential services in the retail sector, including discount stores, grocers, drug stores and pharmacies, home improvement, automotive service and quick-service restaurants, which we refer to as defensive retail industries. The defensive sub-categories as we define them are as follows: (1) Necessity, which are retailers that are considered essential by consumers and include sectors such as drug stores, grocers and home improvement, (2) Discount, which are retailers that offer a low price point and consist of off-price and dollar stores, (3) Service, which consist of retailers that provide services rather than goods, including, tire and auto services and quick service restaurants, and (4) Other, which are retailers that are not considered defensive in terms of being considered necessity, discount or service, as defined by us. Leases are individual properties with a distinct lease agreement in place, development activities where a lease is expected at a future date, or in the case of master lease arrangements each property under the master lease is counted as a separate lease. Net Debt is computed by us as the principal amount of total debt outstanding less cash, cash equivalents, and restricted cash. Occupancy is expressed as a percentage, and it is the number of economically occupied properties divided by the total number of properties owned. Properties under development are excluded from the calculation. OP units means operating partnership units not held by NETSTREIT.
