Portsmouth Square is a holding company whose sole operating asset is the Hilton San Francisco Financial District, a 558-room full-service hotel located in San Francisco, California. The company generates revenue primarily through room rentals to business, convention, group, and leisure travelers, complemented by food and beverage sales and a multi-level parking garage. Portsmouth Square also holds investments in marketable securities. Under its operating model, Portsmouth Square owns the hotel real estate and retains the full economic risk and operational returns, but contracts day-to-day property operations to a third-party manager, Aimbridge Hospitality. The hotel operates as a franchise under the Hilton brand, providing access to Hilton's global reservation network and customer loyalty program. The business is subject to seasonal demand fluctuations, with lower activity during the winter holiday period, and maintains a largely unionized hotel staff. Portsmouth Square is majority-owned and controlled by InterGroup.
