CoStar Group Full Year and Fourth Quarter 2020 Revenues Increased 19% Year-over-Year

Traffic to CoStar Group’s Marketplaces Grew 29% in the Fourth Quarter

WASHINGTON – February 23, 2021 - CoStar Group, Inc. (NASDAQ: CSGP), the leading provider of commercial real estate information, analytics and online marketplaces, announced today that revenue for the year ended December 31, 2020, was $1.66 billion, an increase of 19% over revenue of $1.4 billion for the full year of 2019. Revenue for the fourth quarter ended December 31, 2020, was $444 million, an increase of 19% over revenue of $375 million for the fourth quarter of 2019.

Net income for the year ended December 31, 2020, was $227 million, or $5.93 per diluted share. EBITDA for the full year of 2020 was $406 million and includes one-time charges of $59.5 million related to the now terminated RentPath acquisition. Excluding these one-time charges, EBITDA for the full year of 2020 was $466 million, an increase of 5% compared to EBITDA of $445 million for the full year of 2019. Net Income, excluding the one-time charges, was approximately $271 million, or $7.08 per diluted share.

Adjusted EBITDA (which excludes stock-based compensation, acquisition and integration related costs and other items as described below) for the fourth quarter ended December 31, 2020, was $167 million, an increase of 18% compared to adjusted EBITDA of $142 million for the fourth quarter of 2019. Adjusted EBITDA for the year ended December 31, 2020 was $553 million, an increase of 9% compared to adjusted EBITDA of $507 million for the full year of 2019.

“2020 was an exceptional year for CoStar Group in many ways,” said Andrew C. Florance, Founder and Chief Executive Officer of CoStar Group. “Following the initial pandemic disruption early in the year, we demonstrated that our business is strongly countercyclical as our sales rebounded strongly in the second half of the year. In the fourth quarter, we delivered annualized net new sales of $49 million, bringing our total sales bookings to over $100 million in the second half of 2020. Revenue increased by over a quarter of a billion dollars in 2020. I am particularly pleased that CoStar Suite had its best sales quarter of 2020 in the fourth quarter, more than doubling the third quarter sales level. Unique visitors to our marketplaces increased by over 20% for the year and by 29% in the fourth quarter as the pandemic led more people to shop for real estate online. We raised $2.7 billion in the debt and equity markets and completed the acquisitions of Ten-X, Emporis, and Homesnap, and are well into developing additional important acquisition opportunities – all while working remotely.”

“Apartments.com turned in its strongest performance since we first launched the platform in 2015,” continued Florance, “with revenues growing 22% to almost $600 million. Apartments.com net new sales increased 35% for the year, network visits grew 20% to over 1 billion in 2020, and quality leads to our customers increased over 20%. We believe that our increased investment in marketing for Apartments.com in 2020 was a key driver in our performance and produced outstanding results.”

The LoopNet marketplace network also had a record year, with revenue growth of 20% in 2020 and average monthly unique visitors of approximately 9.4 million in the fourth quarter of 2020, an increase of 37% over the fourth quarter of 2019. Our highest ad levels — gold, diamond, and platinum — are proving to be strongly countercyclical, with revenue growing almost 50% in 2020 and net new sales increasing 100% during the year. In 2020, we invested in marketing and successfully accelerated Apartments.com growth. In 2021, we plan to significantly accelerate our investment in LoopNet’s marketing and sales force and believe we will similarly accelerate LoopNet’s growth.

Non-GAAP net income for the fourth quarter of 2020 was $112 million or $2.85 per diluted share.

2021 Outlook

The Company expects revenue in the range of $1.925 billion to $1.945 billion for the full year of 2021, representing growth of approximately 17% year-over-year at the midpoint of the range. This guidance includes an estimated 2021 revenue contribution from Homesnap of approximately $50 million. We expect revenue for the first quarter of 2021 in the range of $450 million to $455 million, representing revenue growth of 15% year-over-year at the midpoint of the range.

The Company expects adjusted EBITDA in a range of $640 million to $650 million for the full year of 2021, an increase of 17% at the midpoint of the range compared to 2020. Homesnap is expected to have negative adjusted EBITDA of approximately $5 million for the year. For the first quarter of 2021, the Company expects adjusted EBITDA in a range of $140 million to $145 million.

We expect full year 2021 non-GAAP net income per diluted share in a range of $10.83 to $11.03 based on 39.7 million shares. For the first quarter of 2021, we expect non-GAAP net income per diluted share in a range of $2.33 to $2.43 based on 39.5 million shares. These ranges include an estimated non-GAAP tax rate of 25% for the full year and the first quarter 2021.

The preceding forward-looking statements reflect CoStar Group’s expectations as of February 23, 2021, including forward-looking non-GAAP financial measures on a consolidated basis, based on current estimates, expectations, observations and trends. Given the risk factors, rapidly evolving economic environment, and uncertainties and assumptions discussed in this release and in our quarterly reports on Form 10-Q and annual reports on Form 10-K, including uncertainties as a result of the COVID-19 pandemic and responses to it by, and the impact on, global economies, actual results may differ materially. Other than in publicly available statements, the Company does not intend to update its forward-looking statements until its next quarterly results announcement.

Reconciliation of EBITDA, adjusted EBITDA, non-GAAP net income and non-GAAP net income per diluted share to their GAAP basis results are shown in detail below, along with definitions for those terms. A reconciliation of forward-looking non-GAAP guidance to the most directly comparable GAAP measure, net income, can be found within the tables included in this release.

Non-GAAP Financial Measures

For information regarding the purpose for which management uses the non-GAAP financial measures disclosed in this release and why management believes they provide useful information to investors regarding the Company’s financial condition and results of operations, please refer to the Company’s latest periodic report.

EBITDA is a non-GAAP financial measure that represents GAAP net income attributable to CoStar Group before interest (expense) income and other (expense) income, loss on debt extinguishment, income taxes, depreciation and amortization.

Adjusted EBITDA is a non-GAAP financial measure that represents EBITDA before stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, and settlements and impairments incurred outside the Company’s normal course of business.

Non-GAAP net income is a non-GAAP financial measure determined by adjusting GAAP net income attributable to CoStar Group for stock-based compensation expense, acquisition- and integration-related costs, restructuring costs, settlement and impairment costs incurred outside the Company's normal course of business and loss on debt extinguishment, as well as amortization of acquired intangible assets and other related costs, and then subtracting an assumed provision for income taxes. In 2020, the Company is assuming a 25% tax rate in order to approximate our statutory corporate tax rate excluding the impact of discrete items.

Non-GAAP net income per diluted share is a non-GAAP financial measure that represents non-GAAP net income divided by the number of diluted shares outstanding for the period used in the calculation of GAAP net income per diluted share. For periods with GAAP net losses and non-GAAP net income, the weighted average outstanding shares used to calculate non-GAAP net income per share includes potentially dilutive securities that were excluded from the calculation of GAAP net income per share as the effect was anti-dilutive.

Earnings Conference Call

Management will conduct a conference call at 5:00 PM EST on Tuesday, February 23, 2021 to discuss earnings results for the fourth quarter and year ended 2020 and the Company’s outlook.
