Non-GAAP Net Income (Loss) per Share
Our presentation of non-GAAP net income (loss) per share excludes the impact of share-based compensation expense, impairment costs, the gain (loss) on extinguishment of the 2021 Notes and income taxes. This measure is not a key metric used by our management and board of directors to measure operating performance or otherwise manage the business. However, we provide non-GAAP net income (loss) per share as supplemental information to investors, as we believe the exclusion of share-based compensation expense, impairment costs, the gain (loss) on extinguishment of the 2021 Notes and income taxes facilitates investors’ operating performance comparisons on a period-to-period basis. You should not consider non-GAAP net income (loss) per share in isolation or as a substitute for analysis of our results as reported under GAAP.

The following table sets forth a reconciliation of non-GAAP net income (loss), adjusted, to net income (loss), as reported on a GAAP basis, and the calculation of non-GAAP net income (loss) per share - basic and diluted, for each of the periods presented (in thousands, except per share data, unaudited):

Non-GAAP Average Return on Homes Sold After Interest Expense

To provide investors with additional information regarding our Zillow Offers financial results, this Exhibit includes a calculation of Average Return on Homes Sold After Interest Expense, which is a non-GAAP financial measure. We have provided a reconciliation of Average Return on Homes Sold After Interest Expense to the most directly comparable GAAP financial measure, which is average gross profit per home for the Zillow Offers business.
We believe that Average Return on Homes Sold After Interest Expense is a useful financial measure to investors as it is one of the primary measures used by management in making investment decisions, measuring unit level economics and evaluating operating performance for the Zillow Offers business. The measure is intended to convey the unit level economics of homes sold during the period by presenting the average revenue and associated expenses directly attributed to the homes sold. We believe this average per unit measure facilitates meaningful period over period comparisons notwithstanding variability in the number of homes sold during a period and indicates ability to generate average returns on assets sold after considering home purchase costs, renovation costs, holding costs and selling costs.

We calculate the Average Return on Homes Sold After Interest Expense as revenue associated with homes sold during the period less direct costs attributable to those homes divided by the number of homes sold during the period. Specifically, direct costs include, with respect to each home sold during the period (1) home acquisition and renovation costs, which in turn include certain labor costs directly associated with these activities; (2) holding and selling costs; and (3) interest costs incurred.

Included in direct holding and interest expense amounts for the periods presented are holding and interest costs recorded as period expenses in prior periods associated with homes sold in the presented period, which are not calculated in accordance with, or as an alternative for, GAAP and should not be considered in isolation or as a substitute for results reported under GAAP. Excluded from certain of these direct cost amounts are costs recorded in the presented period related to homes that remain in inventory at the end of the period, as shown in the tables below. We make these period adjustments because we believe presenting Average Return on Homes Sold After Interest Expense in this manner provides a focused view on a subset of our assets - homes sold during the period - and reflecting costs associated with those homes sold from the time we acquire to the time we sell the home, which may be useful to investors.

Average Return on Homes Sold After Interest Expense is intended to illustrate the performance of homes sold during the period and is not intended to be a segment or company performance metric. Average Return on Homes Sold After Interest Expense is a supplemental measure of operating performance for a subset of assets and has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Average Return on Homes Sold After Interest Expense does not reflect capital expenditure requirements for such replacements or for new capital expenditure requirements;
Average Return on Homes Sold After Interest Expense does not consider the potentially dilutive impact of share-based compensation;
Average Return on Homes Sold After Interest Expense does not include period costs that were not eligible for inventory capitalization associated with homes held in inventory at the end of the period;



Average Return on Homes Sold After Interest Expense does not reflect indirect expenses included in cost of revenue, sales and marketing, technology and development, or general and administrative expenses, some of which are recurring cash expenditures necessary to operate the business; and
Average Return on Homes Sold After Interest Expense does not reflect income taxes.

On a GAAP basis, Zillow Offers average gross profit per home was $29,547 and $11,477, respectively, for the three months ended December 31, 2020 and 2019.

The following table presents the total return on homes sold after interest expense and the Average Return on Homes Sold After Interest Expense for the periods presented (unaudited):

(1) Amount excludes expenses incurred during the period that are not related to homes sold during the period.
(2) Holding costs and interest expense include $1.4 million and $0.6 million, respectively, of costs incurred in prior periods associated with homes sold in the fourth quarter of 2020 and $4.4 million and $5.1 million, respectively, of costs incurred in prior periods associated with homes sold in the fourth quarter of 2019.




The calculation of Average Return on Homes Sold After Interest Expense includes only those expenses directly attributed to the homes sold during the period. To arrive at return on homes sold after interest expense, the Company deducts from Zillow Offers gross profit (1) holding costs incurred in the presented period and prior periods for homes sold during the presented period that are included in sales and marketing expense, (2) selling costs incurred in the presented period for homes sold during the presented period that are included in sales and marketing expense and (3) interest expense incurred in the presented period and prior periods for homes sold during the presented period. The Company adds to Zillow Offers gross profit (1) inventory valuation adjustments recorded during the presented period associated with homes that remain in inventory at period end, net of inventory valuation adjustments recorded in prior periods related to homes sold in the presented period, and indirect expenses included in cost of revenue and (2) share-based compensation expense and depreciation and amortization expense included in cost of revenue.
