Sotheby’s is navigating a complex financial landscape marked by a major debt refinancing effort and the introduction of a controversial delayed-payment program. The auction house is seeking to raise $825 million through five-year bonds to address existing debt due in 2027, while simultaneously facing a $10.2 million lawsuit over real estate commissions. To manage liquidity, the firm has codified a scheme offering sellers a 7 percent interest rate if they agree to wait six months for their payout, a significant departure from the industry standard of 35 to 45 days.
