Investing.com -- Cassandra Seier, the New York Stock Exchange’s head of international capital markets, died over the weekend, a company spokesperson confirmed on Monday. The cause of death was not disclosed.

"We are devastated by the news that our colleague Cassanda Seier passed away over the weekend," an NYSE spokesperson said in an email statement.

Seier had spent over 23 years at Goldman Sachs. At NYSE, Seier played a crucial role in attracting new foreign issuers from outside the United States, a position vital to revenue generation as the exchange navigates competition in an increasingly crowded market.

NYSE President Lynn Martin paid tribute to Seier on Monday in a LinkedIn post, writing: "She was someone who was laser focused on getting a job done but always found time to offer anyone support and to mentor the next generation of leaders."
