Exceeds prior expectations for fourth quarter and full year 2020 results
Doubling of markets expected for 2021

SAN FRANCISCO, March 04, 2021 (GLOBE NEWSWIRE) -- Opendoor Technologies Inc. (Nasdaq: OPEN), a leading digital platform for residential real estate, today reported financial results for its fourth quarter and fiscal year ended December 31, 2020. Management will host a conference call at 2:00 p.m. Pacific Time today to discuss its operating results, which can be accessed on its investor relations website at https://investor.opendoor.com.

“We are making it possible to buy and sell a home at the tap of a button and building the future of the real estate transaction,” said Eric Wu, Co-Founder and CEO of Opendoor. “While 2020 was an unprecedented year, I’m proud of our team’s relentless focus on digitizing the transaction and delighting customers. As we reflect on Q4 and enter 2021, this focus has resulted in increasing business momentum. More customers are coming to us and choosing Opendoor than ever before, we are seeing healthy margins, and we plan on doubling our footprint to 42 markets. Since creating the category seven years ago, we have generated over $10 billion in home sales, served over 80,000 customers and demonstrated our ability to scale efficiently. While we are pleased with the progress and foundation we've built, we are just getting started.”

Fourth Quarter and Full Year 2020 Financial Summary
Revenue and Homes Sold
Revenue for the full year and fourth quarter exceeded prior company forecasts as a result of strong home resale performance and an increased acquisition pace after pausing home purchases in March at the onset of the COVID-19 pandemic. The decision to temporarily pause home buying, and the subsequent sell down of homes in inventory over the second and third quarters, drove a significant decline in revenue in 2020. The Company began rebuilding inventory in the fourth quarter, and expects to return to sequential revenue growth in the first quarter of 2021.

• For the fourth quarter, Total Homes Sold was 849, as compared to 5,013 for the prior year period, and Total Revenue was $248.9 million, as compared to $1,255.7 million for the prior year period.
• For the full year 2020, Total Homes Sold was 9,913, compared to 18,799 for the prior year, and Total Revenue was $2,583.1 million, as compared to $4,740.6 million for 2019.

Margins
Opendoor realized increases in unit margins, particularly in the fourth quarter, largely driven by a combination of inventory weighted to recently acquired homes, coupled with home price appreciation in its markets. Contribution Margins are expected to moderate with the rebuilding of inventory over the course of the year.

• For the fourth quarter, GAAP Gross Profit was $38.4 million or 15.4% of total revenue, compared to $74.0 million or 5.9% of total revenue for the prior year period. Gross Profit per Home Sold was $45,188 compared to prior year Gross Profit per Home Sold of $14,754. Contribution Profit was $31.5 million and Contribution Margin was 12.6%, as compared to Contribution Profit of $18.2 million and Contribution Margin of 1.5%. Contribution Margin after Interest was 12.2% as compared to 0.2%. Contribution Profit per Home Sold was $37,052 compared to prior year period Contribution Profit per Home Sold of $3,635.
• For the full year, GAAP Gross Profit was $219.8 million or 8.5% of total revenue, compared to $301.3 million or 6.4% of total revenue for 2019. Gross Profit per Home Sold was $22,173 compared to 2019 Gross Profit per Home Sold of $16,025. Contribution Profit was $110.1 million and Contribution Margin was 4.3% as compared to Contribution Profit of $92.1 million and Contribution Margin of 1.9%. Contribution Margin after Interest was 3.2% as compared to 0.6%. Contribution Profit per Home Sold was $11,109 compared to prior year Contribution Profit per Home Sold of $4,897.

Net Income (Loss) and Adjusted EBITDA
Net Income (Loss) and Adjusted EBITDA improvement year-over-year was due to improved Contribution Margin performance and prudent operating expense controls put in place as the Company managed through the uncertainty of COVID-19.

• For the fourth quarter, GAAP Net Loss was $(87.8) million as compared to $(91.7) million for the prior year period. Non-GAAP Adjusted Net Loss was $(41.3) million as compared to $(86.6) million. Adjusted EBITDA was $(27.1) million or (10.9)% Adjusted EBITDA Margin, as compared to $(59.0) million or (4.7)%.
• For the full year, GAAP Net Loss was $(286.8) million as compared to $(339.2) million for 2019. Non-GAAP Adjusted Net Loss was $(175.1) million as compared to $(326.8) million. Adjusted EBITDA was $(98.0) million or (3.8)% Adjusted EBITDA Margin, as compared to $(217.9) million or (4.6)%.

First Quarter 2021 Outlook
For the first quarter of 2021, Total Revenue is expected to be between $600 million and $625 million, which represents 146% sequential growth over Q4 2020 at the midpoint of the expected range. This first fiscal quarter is expected to mark a return to sequential revenue growth across existing markets with strong and increasing demand for Opendoor’s service and an accelerating pace of home acquisitions. The Company expects to launch six new markets in Q1.

Adjusted EBITDA¹ is expected to be between $(33) million and $(28) million, which represents Adjusted EBITDA margins of (5)% at the midpoint of the expected range.

Use of Non-GAAP Financial Measures
To provide investors with additional information regarding the Company’s financial results, this press release includes references to certain non-GAAP financial measures that are used by management. The Company believes these non-GAAP financial measures including Adjusted Gross Profit, Contribution Profit, Contribution Profit After Interest, Adjusted Net Loss, Adjusted EBITDA, and any such non-GAAP financial measures expressed as a Margin, are useful to investors as supplemental operational measurements to evaluate the Company’s financial performance. The non-GAAP financial measures should not be considered in isolation or as a substitute for the Company’s reported GAAP results because they may include or exclude certain items as compared to similar GAAP-based measures, and such measures may not be comparable to similarly-titled measures reported by other companies. Management uses these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding the Company’s performance by excluding certain items that may not be indicative of the Company’s recurring operating results.

For more information on the Company’s non-GAAP financial measures, please see “Non-GAAP Financial Measures” and “Reconciliation of GAAP to Non-GAAP Measures” included at the end of this press release.

The absence of these words does not mean that a statement is not forward-looking. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many important factors could cause actual future events to differ materially from the forward-looking statements in this press release, including but not limited to our public securities’ potential liquidity and trading; our ability to raise financing in the future; our success in retaining or recruiting, or changes required in, our offices, key employees or directors; the impact of the regulatory environment and complexities with compliance related to such environment; our ability to remediate our material weakness; various factors relating to our business, operations and financial performance, including, but not limited to, the impact of the COVID-19 pandemic and our ability to grow market share; our ability to respond to general economic conditions and the health of the U.S. residential real estate industry. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described under the caption "Risk Factors" in our annual report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2021 and our other filings with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made.

_____________________________
¹ Opendoor has not provided a quantitative reconciliation of forecasted Adjusted EBITDA to forecasted GAAP net income (loss) within this press release because the Company is unable, without making unreasonable efforts, to calculate certain reconciling items with confidence. These items include, but are not limited to, inventory impairment and stock-based compensation with respect to future grants and forfeitures. These items, which could materially affect the computation of forward-looking GAAP net income (loss), are inherently uncertain and depend on various factors, some of which are outside of the Company’s control.

Non-GAAP Financial Measures

In addition to our results of operations below, we report certain financial measures that are not required by, or presented in accordance with, U.S. generally accepted accounting principles (“GAAP”).

These measures have limitations as analytical tools when assessing our operating performance and should not be considered in isolation or as a substitute for GAAP measures, including gross profit and net income. We may calculate or present our non-GAAP financial measures differently than other companies who report measures with similar titles and, as a result, the non-GAAP financial measures we report may not be comparable with those of companies in our industry or in other industries.

Adjusted Gross Profit, Contribution Profit and Contribution Profit After Interest

To provide investors with additional information regarding our margins and return on inventory acquired, we have included Adjusted Gross Profit, Contribution Profit and Contribution Profit After Interest, which are non-GAAP financial measures. We believe that Adjusted Gross Profit, Contribution Profit and Contribution Profit After Interest are useful financial measures for investors as they are supplemental measures used by management in evaluating unit level economics and our operating performance in our key markets. Each of these measures is intended to present the economics related to homes sold during a given period. We do so by including revenue generated from homes sold (and adjacent services) in the period and only the expenses that are directly attributable to such home sales, even if such expenses were recognized in prior periods, and excluding expenses related to homes that remain in inventory as of the end of the period. Contribution Profit provides investors a measure to assess Opendoor’s ability to generate returns on homes sold during a reporting period after considering home purchase costs, renovation and repair costs, holding costs and selling costs. Contribution Profit After Interest further impacts gross profit by including interest costs attributable to homes sold during a reporting period. We believe these measures facilitate meaningful period over period comparisons and illustrate our ability to generate returns on assets sold after considering the costs directly related to the assets sold in a given period.

Adjusted Gross Profit, Contribution Profit and Contribution Profit After Interest are supplemental measures of our operating performance and have limitations as analytical tools. For example, these measures include costs that were recorded in prior periods under GAAP and exclude, in connection with homes held in inventory at the end of the period, costs required to be recorded under GAAP in the same period. These measures also exclude the impact of certain restructuring costs that are required under GAAP. Accordingly, these measures should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. We include a reconciliation of these measures to the most directly comparable GAAP financial measure, which is gross profit.

Adjusted Gross Profit / Margin

We calculate Adjusted Gross Profit as gross profit under GAAP adjusted for (1) inventory impairment in the current period, (2) inventory impairment in prior periods, plus (3) restructuring in cost of revenue. Restructuring in cost of revenue reflects the costs associated with the reduction in our workforce in 2020, a portion of which were related to personnel included in cost of revenue. Inventory impairment in the current period is calculated by adding back the inventory impairment charges recorded during the period on homes that remain in inventory at period end. Inventory impairment in prior periods is calculated by subtracting the inventory impairment charges recorded in prior periods on homes sold in the current period. We define Adjusted Gross Margin as Adjusted Gross Profit as a percentage of revenue.

We view this metric as an important measure of business performance as it captures gross margin performance isolated to homes sold in a given period and provides comparability across reporting periods. Adjusted Gross Profit helps management assess home pricing, service fees and renovation performance for a specific resale cohort.

Contribution Profit / Margin

We calculate Contribution Profit as Adjusted Gross Profit, minus (1) holding costs incurred in the current period on homes sold during the period, minus (2) holding costs incurred in prior periods on homes sold in the current period, and (3) direct selling costs incurred on homes sold during the current period. The composition of our holding costs is described in the footnotes to the reconciliation table below. Contribution Margin is Contribution Profit as a percentage of revenue.

We view this metric as an important measure of business performance as it captures the unit level performance isolated to homes sold in a given period and provides comparability across reporting periods. Contribution Profit helps management assess inflows and outflows directly associated with a specific resale cohort.

Contribution Profit / Margin After Interest

We define Contribution Profit After Interest as Contribution Profit, minus interest expense under our senior revolving credit facilities incurred on the homes sold during the period. This may include interest expense recorded in periods prior to the period in which the sale occurred. Our senior revolving credit facilities are secured by our homes in inventory and drawdowns are made on a per-home basis at the time of purchase and are required to be repaid at the time the homes are sold. We do not include interest expense associated with our mezzanine term debt facilities in this calculation as we do not view such facilities as reflective of our expected long term capital structure and cost of financing. Contribution Margin After Interest is Contribution Profit After Interest as a percentage of revenue.

We view this metric as an important measure of business performance. Contribution Profit After Interest helps management assess Contribution Margin performance, per above, when fully burdened with expected long-term costs of financing.

Adjusted Net Loss and Adjusted EBITDA

We also present Adjusted Net Loss and Adjusted EBITDA, which are non-GAAP financial measures that management uses to assess our underlying financial performance. These measures are also commonly used by investors and analysts to compare the underlying performance of companies in our industry. We believe these measures provide investors with meaningful period over period comparisons of our underlying performance, adjusted for certain charges that are non-recurring, non-cash, not directly related to our revenue-generating operations or not aligned to related revenue.

Adjusted Net Loss and Adjusted EBITDA are supplemental measures of our operating performance and have important limitations. For example, these measures exclude the impact of certain costs required to be recorded under GAAP. These measures also include impairment costs that were recorded in prior periods under GAAP and exclude, in connection with homes held in inventory at the end of the period, impairment costs required to be recorded under GAAP in the same period. These measures could differ substantially from similarly titled measures presented by other companies in our industry or companies in other industries. Accordingly, these measures should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. We include a reconciliation of these measures to the most directly comparable GAAP financial measure, which is net loss.

Adjusted Net Loss

We calculate Adjusted Net Loss as GAAP net loss adjusted to exclude non-cash expenses of stock-based compensation, derivative and warrant fair value adjustment and intangible amortization. It also excludes non-recurring restructuring charges, loss on extinguishment of debt, and convertible note payment-in-kind (“PIK”) interest and issuance discount amortization. Adjusted Net Loss also aligns the timing of impairment charges recorded under GAAP to the period in which the related revenue is recorded in order to improve the comparability of this measure to our non-GAAP financial measures of unit economics, as described above. Our calculation of Adjusted Net Loss does not currently include the tax effects of the non-GAAP adjustments because our taxes and such tax effects have not been material to date.

Adjusted EBITDA

We calculated Adjusted EBITDA as Adjusted Net Loss adjusted for depreciation and amortization, property financing and other interest expense, interest income, and income tax expense. Adjusted EBITDA is a supplemental performance measure that our management uses to assess our operating performance and the operating leverage in our business.

The following table presents a reconciliation of our Adjusted Net Loss and Adjusted EBITDA to our net loss, which is the most directly comparable GAAP measure, for the periods indicated:

________________

(1)		Represents the gains and losses on our derivative and warrant liabilities, which are marked to fair value at the end of each period.
(2)		Represents amortization of intangibles acquired in the OS National LLC and Open Listings Co acquisitions which contribute to revenue generation and are recorded as part of purchase accounting. The acquired intangible assets have useful lives ranging from 2 to 5 years and amortization is expected until the intangible assets are fully amortized.
(3)		Inventory impairment — Current Period is the inventory impairment charge recorded during the period presented associated with homes that remain in inventory at period end.
(4)		​Inventory impairment — Prior Periods is the inventory valuation adjustments recorded in prior periods associated with homes that sold in the period presented.
(5)		Restructuring costs consist mainly of employee termination benefits, relocation packages and retention bonuses as well as costs related to the exiting of certain non-cancelable leases. In 2020, these costs related mainly to a reduction in workforce implemented in April 2020 as well as our exercise of the early termination option related to our San Francisco headquarters. In 2019, these costs related mainly to the centralization of our administrative and selling functions, including the relocation of local teams to Phoenix.
(6)		​Includes non-cash payment-in-kind (“PIK”) interest and amortization of the discount on the convertible notes issued from July through November 2019. We exclude convertible note PIK interest and amortization from Adjusted Net Loss since these are non-cash in nature and were converted into equity in September 2020 when the Company entered into a Convertible Notes Exchange Agreement with the convertible note holders.
(7)		Includes primarily gain or loss on disposal of fixed assets, gain or loss on interest rate lock commitments, gain or loss on the sale of marketable securities, accrued legal matters and sublease income.
(8)		Includes interest expense on our senior revolving credit facilities and our asset-backed mezzanine term debt facilities.
(9)		Includes amortization of debt issuance costs and loan origination fees, commitment fees, unused fees, and other interest related costs on our senior revolving credit facilities and our mezzanine term debt facilities.
(10)		Consists mainly of interest earned on cash, cash equivalents and marketable securities.
