Third Point launches proxy fight to overhaul CoStar's failing leadership

Hedge fund Third Point has launched a public challenge against CoStar, demanding leadership changes and operational reforms. In a letter sent to the company's board, the activist investor criticized poor governance, weak financial performance, and failed business strategies under current management.

The move signals the start of a proxy fight, with Third Point pushing for new directors and immediate improvements at the commercial real estate data firm.

On January 27, 2026, Third Point—led by billionaire investor Daniel Loeb—sent a strongly worded letter to CoStar's board. The fund accused CEO Andy Florance of mismanaging an online classifieds venture in residential real estate, calling it a costly failure. It also highlighted broader concerns, including weak board oversight, misaligned executive incentives, and poor capital allocation.

Third Point announced plans to nominate a slate of experienced directors to the board, though no names were disclosed. The letter urged immediate operational changes but did not outline specific measures. As of early Tuesday evening, CoStar had not issued a public response. The fund's intervention follows years of underperformance. CoStar's stock has fallen by 27% over the past five years, lagging the S&P 500 by 121% in the same period. Third Point argued that leadership failures have eroded shareholder value and called for urgent action to reverse the decline.

Third Point's campaign marks the first step in a potential boardroom battle for control of CoStar. The fund's proposed director nominations and operational demands will likely face resistance from existing leadership. Shareholders now await further developments as the proxy fight unfolds.
