CHANDLER, AZ – June 1, 2021 – Offerpad, Inc. (“Offerpad”) the tech-enabled Real Estate Solutions Center and a leading iBuyer today reported financial results for its first quarter ended March 31, 2021.

“Consumer expectations continue to evolve and transform the way we sell and buy homes, and we are seeking to meet and exceed those expectations with our range of digital real estate solutions. The real estate market is highly competitive, and buyers and sellers are turning to Offerpad because of the convenience, certainty and control our one-stop Real Estate Solutions Center provides,” said Brian Bair, CEO and founder of Offerpad. “Offerpad closed the first quarter of 2021 with strong momentum due to favorable market conditions, operational excellence across our company and the increasing willingness of consumers to adopt the digital real estate solutions we provide. Total company revenue increased 27.2% to $284 million from Q4 2020 and is expected to increase on a year over year basis for the remaining quarters of the year. Now it’s time to bring the power of Offerpad to more markets and homeowners this year and in 2022.”

First Quarter 2021 Operating Highlights

• Announced plans to become publicly traded via a merger with Supernova Partners Acquisition Company (“Supernova”). The transaction, which is expected to close early in the third quarter of 2021 (subject to satisfaction of customary closing conditions), is expected to result in Offerpad’s common stock being listed on the NYSE under the ticker “OPAD”

• Expanded market footprint to Denver, CO and Nashville, TN in March, and announced plans to further expand to Indianapolis, IN in the third quarter of 2021 bringing the total market count to 17

• Generated positive adjusted EBITDA for the second consecutive quarter

• Launched Offerpad’s Extended Stay service, allowing home sellers to remain in their home up to 60 days after closing

Despite the year over year decline in revenue due to the impact of the COVID-19 pandemic on the company’s home acquisitions in the second half of 2020, total company revenue increased 27.2% to $284 million sequentially from Q4 2020 and is expected to increase on a year over year basis for the remaining quarters of the year.

Gross profit of $33.5 million in the first quarter of 2021 increased 34.7%, or $8.6 million, over the first quarter of 2020. Gross margin increased 500 basis points to 11.8% as Offerpad generated more in absolute gross profit dollars in the current period on less reported revenue than in the first quarter of 2020.

Contribution profit increased 76% to $25.7 million, from $14.6 million in Q1 of 2020, and contribution margin percentage increased 500 basis points to 9.0%, from 4.0% in the prior year.

Overall unit economics improved significantly in the quarter as contribution profit after interest increased to $23.5 million, from $7.8 million in the first quarter of the prior year. Contribution profit after interest per home sold improved to $23,100 compared to $5,100 for the prior year period, reflecting continued disciplined operations and prudent cost containment within the backdrop of favorable market conditions.

Adjusted EBITDA increased $8.3 million to $3.0 million, compared to $(5.2) million in the first quarter of the prior year. This is the second consecutive quarter that Offerpad had generated positive Adjusted EBITDA, demonstrating its ability to operate in slower growth environments, even at its current scale.

Non-GAAP Financial Measures

In addition to Offerpad’s results of operations above, Offerpad’s management utilizes 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 Offerpad’s operating performance and should not be considered in isolation or as a substitute for GAAP measures, including gross profit and net income. Offerpad may calculate or present its non-GAAP financial measures differently than other companies who report measures with similar titles and, as a result, the non-GAAP financial measures Offerpad reports may not be comparable with those of companies in its industry or in other industries.

Adjusted gross profit, contribution profit, and contribution profit after interest (and related margins)

Offerpad believes that adjusted gross profit, contribution profit, and contribution profit after interest are useful financial measures for investors as they are used by management in evaluating unit level economics and operating performance across its markets. Each of these measures is intended to present the economics related to homes sold during a given period. Offerpad does so by including revenue generated from homes sold (and ancillary 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 presented. Contribution profit provides investors a measure to assess Offerpad’s ability to generate returns on homes sold during a reporting period after considering home acquisition costs, renovation and repair costs, and adjusting for holding costs and selling costs. Contribution profit after interest further impacts gross profit by including interest costs (including senior and mezzanine secured credit facilities) attributable to homes sold during a reporting period. Offerpad believes 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 presented period.

Adjusted gross profit, contribution profit and contribution profit after interest (and related margins) are supplemental measures of Offerpad’s 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. Accordingly, these measures should not be considered in isolation or as a substitute for analysis of Offerpad’s results as reported under GAAP. Offerpad includes a reconciliation of these measures to the most directly comparable GAAP financial measure, which is gross profit.

Adjusted gross profit / margin

Offerpad calculates adjusted gross profit as gross profit under GAAP adjusted for (1) net inventory impairment plus (2) interest expense associated with homes sold in the presented period and recorded in cost of sales. Net inventory impairment is calculated by adding back the inventory impairment charges recorded during the period on homes that remain in inventory at period end and subtracting the inventory impairment charges recorded in prior periods on homes sold in the current period. Offerpad defines adjusted gross margin as adjusted gross profit as a percentage of revenue.

Offerpad views 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 performance across the key phases of processing a home (acquisitions, renovations, and resale) for a specific resale cohort.

Contribution profit / margin

Offerpad calculates contribution profit as adjusted gross profit, minus (1) direct selling costs incurred on homes sold during the presented period, minus (2) holding costs incurred in the current period on homes sold during the period recorded in sales, marketing, and operating, minus (3) holding costs incurred in prior periods on homes sold in the current period recorded in sales, marketing, and operating, plus (4) other income which historically is primarily comprised of net income to us from the investment related to Offerpad’s OPHL operations. The composition of Offerpad’s holding costs is described in the footnotes to the reconciliation table below. Offerpad defines contribution margin as contribution profit as a percentage of revenue.

Offerpad views 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 outflow directly associated with a specific resale cohort.

Contribution profit / margin after interest

Offerpad defines contribution profit after interest as contribution profit, minus (1) interest expense associated with homes sold in the presented period and recorded in cost of sales, minus (2) interest expense associated with homes sold in the presented period, recorded in costs of sales, and previously excluded from adjusted gross profit, and minus (3) interest expense under Offerpad’s senior and mezzanine secured credit facilities incurred on homes sold during the period. This includes interest expense recorded in prior periods in which the sale occurred. Offerpad’s senior and mezzanine secured credit facilities are secured by its 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. Offerpad defines contribution margin after interest as contribution profit after interest as a percentage of revenue.

Offerpad views 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 costs of financing.

(1) Inventory impairment – current period is the inventory valuation adjustments recorded during the period presented associated with homes that remain in inventory at period end.

(2) Inventory impairment – prior period is the inventory valuation adjustments recorded in prior periods associated with homes that sold in the period presented.

(3) Interest expense capitalized represents all interest related costs, including senior and mezzanine secured credit facilities, incurred on homes sold in the period presented that were capitalized and expensed in cost of sales at the time of sale.

(4) Direct selling costs represents selling costs incurred related to homes sold in the period presented. This primarily includes broker commissions and title and escrow closing fees.

(5) Holding costs primarily include property taxes, insurance, utilities, homeowners association dues, cleaning and maintenance costs.

(6) Represents holding costs incurred on homes sold in the period presented and expensed to Sales, marketing, and operating on the Consolidated Statements of Operations.

(7) Represents holding costs incurred in prior periods on homes sold in the period presented and expensed to Sales, marketing, and operating on the Consolidated Statements of Operations.

(8) Other income primarily consists of net income to Offerpad from our investment in Offerpad Home Loans, except in the presentation of the first quarter of 2021, which represents income from a bulk sale of residential properties.

(9) Represents both senior and mezzanine interest expense incurred on homes sold in the period presented and expensed to interest expense on the Consolidated Statements of Operations.

(10) Represents both senior and mezzanine secured credit facilities interest expense incurred in prior periods on homes sold in the period presented and expensed to Interest expense on the Consolidated Statements of Operations.

Adjusted EBITDA

Offerpad also presents adjusted EBITDA and its related margin, which is a non-GAAP financial measure, which its management team uses to assess its underlying financial performance. Offerpad believes this provides insight into period over period performance, adjusted for non-recurring or non-cash items. Offerpad calculates adjusted EBITDA as GAAP net loss adjusted for interest expense, taxes, amortization of capitalized interest, depreciation and amortization and stock-based compensation expense. Offerpad defines adjusted EBITDA Margin as adjusted EBITDA as a percentage of revenue.

Adjusted EBITDA is supplemental to Offerpad’s operating performance measures calculated in accordance with GAAP and has important limitations. For example, adjusted EBITDA excludes the impact of certain costs required to be recorded under GAAP and could differ substantially from similarly titled measures presented by other companies in its industry or companies in other industries. Accordingly, this measure should not be considered in isolation or as a substitute for analysis of Offerpad’s results as reported under GAAP.

The following table presents a reconciliation of Offerpad’s adjusted EBITDA to its GAAP net loss, which is the most directly comparable GAAP measure, for the periods indicated:

	Three Months Ended March 31,
	2021			2020
Net loss (GAAP)	$	(233	)	$	(11,465	)
Interest expense		1,918			4,674

Depreciation and amortization		130			102
Amortization of share-based compensation		613			249
Adjusted EBITDA		3,034			(5,221	)
Adjusted EBITDA margin		1.1	%		(1.4	%)

(1) Amortization of capitalized interest represents all interest related costs, including senior and mezzanine interest related costs, incurred on homes sold in the period presented that were capitalized and expensed in cost of sales at the time of sale.
