A bit of over a yr in the past, CoStar CEO Andrew Florance sat in a field overlooking Tremendous Bowl LIX, beaming at his creation.
Florance, holding his telephone out in entrance of his face for these round him to see, performed the second of two Properties.com Tremendous Bowl advertisements airing that evening, each directed by Oscar-nominated director Taika Waititi and that includes cameos from Oscar-winning actor Morgan Freeman.
The advertisements have been a part of CoStar’s multi-year, billion-dollar push into the residential market after years of minting cash on its extremely worthwhile industrial actual property platform.
Florance appeared to absorb the publicity that got here with the advertisements. It didn’t harm that the inventory was buying and selling at a decent $76, and was on its means as much as a 12-month excessive of over $97 {dollars} by August 2025.
Simply 9 months later, the inventory is down 65 % and Florance has been heading off broadsides from institutional buyers that declare his spending course has waylaid a as soon as promising firm.
Activist investor Third Level, which had been pressuring CoStar to chop its losses on Properties.com, estimated that the corporate has spent north of $3 billion on the platform over 5 years. However in 2025, the platform generated simply $100 million in income.
The funding has weighed on CoStar’s backside line as effectively. In 2024, CoStar generated a $361 million loss when it comes to adjusted earnings on its residential enterprise, which incorporates Properties.com and a U.Okay.-based market it acquired in 2023, OnTheMarket.com. The next yr, it misplaced one other $230 million.
“Traders in public corporations don’t usually give board of administrators, corporations and administration leeway to construct an organization from scratch and spend billions of {dollars} to do it,” stated Craig Huber, an analyst protecting CoStar and the founding father of Huber Analysis Companions.
CoStar will report its first-quarter efficiency on Tuesday. In January, the corporate stated it expects to hit an adjusted EBITDA vary of $95 million to $115 million for the quarter.
Florance stated in a press release posted to LinkedIn that the agency is “working with conviction and confidence.”
“We’ve engaged with our stockholders around the globe and obtained sturdy assist for our technique,” stated Florance. “We’ve enhanced our Board, launched our transformative Properties Ai and expertise initiatives, deepened our dedication to returning capital to stockholders, and aligned government compensation extra carefully with long-term worth creation.”
“Whereas a small variety of activist buyers have been vocal, no stockholder nominations have been submitted, permitting us to maneuver ahead with out distractions,” Florance added.
An enormous wager
CoStar made its preliminary foray within the residential market when it purchased Homesnap for $250 million in money. The subsequent yr, it added Properties.com for $156 million in one other all-cash deal and later built-in the 2 platforms underneath the Properties.com model.
Midway by 2023, CoStar claimed it had hit 84 million common month-to-month distinctive guests throughout its residential platform, pushing it forward of Realtor.com when it comes to site visitors, however nonetheless effectively behind Zillow’s 226 million common month-to-month distinctive guests. (Realtor.com has additionally disputed customer numbers reported by Properties.com, claiming the positioning depends on deceptive inside site visitors knowledge.)
In contrast to Zillow, which makes cash by directing purchaser site visitors towards paying “Premier Brokers” or charging referral charges on closed transactions, Properties.com has billed itself as a list agent-friendly vacation spot, as a substitute charging itemizing brokers a flat membership price for the chance to spice up itemizing visibility.
The corporate has pushed its “Your Itemizing, Your Lead” mannequin because the trade has confronted an upheaval over how listings are marketed, which resulted in Zillow threatening to ban listings not uploaded to its web site inside 24 hours of public advertising and marketing in Could 2025. Compass responded by suing Zillow, claiming the follow was anticompetitive.
Florance seized on the chance, calling Zillow’s lead-diversion “anti-consumer and anti-agent” in an open letter to brokers, and providing to “increase” listings banned on Zillow without cost.
In July, CoStar additionally sued Zillow, claiming that Zillow’s use of greater than 46,000 CoStar Group photographs on its itemizing web site quantities to “mass infringement.” The lawsuit follows an extended historical past of CoStar suing its opponents within the industrial house over its proprietary picture database, leading to sizable wins, together with a $500 million judgment granted in 2019 towards Xceligent, which had filed for chapter.
However regardless of its aggressive entry into the residential sector, CoStar has not turned its rising public profile into vital income. In 2023, when it counted a whole lot of tens of millions of website visits, Properties.com recorded simply $50 million in annual income.
However Properties.com’s rising customer depend was not essentially taking any site visitors away from its competitors, as customers seem like joyful to browse completely different web sites on their residence search course of, in accordance with a 2024 evaluation by strategist Mike DelPrete.
“In contrast to web site visits, there’s a finite quantity of transactions, fee {dollars}, and brokers prepared to spend cash on-line; that’s a zero-sum recreation,” he wrote.
The investor battle
By 2025, buyers in CoStar started to publicly air their considerations with what they noticed as the corporate’s wayward enterprise.
In an April investor letter, Third Level CEO Daniel Loeb wrote that “Increasing losses at Properties.com have obscured fast progress within the core enterprise.”
Earlier that month, CoStar had introduced the appointment of three new members to the board, an unbiased board chair and the institution of a capital allocation committee to evaluation CoStar’s funding in Properties.com and its timeline for profitability.
“We imagine it’s time for CoStar to start the journey of significant self-help,” Loeb wrote.
CoStar responded in January of this yr by saying it will start slashing its funding in Properties.com by 35 % in 2026 to $550 million, and proceed slicing $100 million yearly till 2030. In February, the corporate additionally laid off 200 employees from Properties.com.
That was not sufficient for Loeb, who issued a scathing letter to CoStar’s board on Jan. 27 during which he known as for a board overhaul and an exit from Properties.com. He additionally took difficulty with Florance’s $37 million pay package deal in 2024, regardless of the corporate’s “terribly poor inventory efficiency over the past 5 years.”
“The Firm’s anemic efficiency may be ascribed solely to the misallocation of billions of {dollars} into Properties.com, overseen by a feckless board of administrators that has failed to guard shareholders from Mr. Florance’s quixotic quest whereas rewarding him with exorbitant pay packages,” Loeb wrote.
CoStar responded with an open letter claiming Third Level’s claims have been “indifferent from actuality” and pointing to the adjustments instituted over the past yr. “Sad with the conclusions of the unbiased Board they helped decide, Third Level, like a toddler with a board recreation, needs to throw the items off the board,” the letter said.
In March, D.E. Shaw, which has aligned with Third Level on an activism marketing campaign, criticized a monetary reporting change made by CoStar for its fourth quarter earnings, during which CoStar mixed its reporting for Properties.com and Residences.com underneath a “Residential” section.
“In our view, CoStar’s ‘cover the ball’ train all however ensures that the Board and administration can’t be held accountable for Properties.com’s future efficiency by the homeowners of the Firm and additional demonstrates the Board’s disregard for shareholder pursuits,” the letter said.
CoStar once more responded by claiming it is going to nonetheless present disaggregated income disclosures, and that it has included extra transparency by reporting income, EBITDA, Adjusted EBITDA and margin disclosures for its “Residential” section.
The next month, Third Level introduced it was ending its activist marketing campaign and liquidating its place in CoStar.
“We now not imagine that our authentic thesis holds true immediately and have disposed of our place in its entirety,” Loeb wrote in an investor letter.
