BRIEF HISTORY
Zions Bancorporation originated as Keystone Insurance and Investment Co., a Utah Corporation, in
April 1955. In April 1960, Keystone, together with several individual investors, acquired a 57.5
percent interest in Zions First National Bank from the LDS Church. In 1965, the name of the
company was changed to Zions Bancorporation. (However, it operated as Zions Utah Bancorporation
from 1966 to 1987.) The first public offering of shares in Zions Bancorporation was made in
January 1966. There continued to be some minority shareholders until April 1972, when the
company exchanged the remaining minority shares for common shares. In 2018, Zions Bancorporation
merged into its bank subsidiary, ZB, N.A., which was then renamed Zions Bancorporation, N.A.
Zions Bancorporation now operates as a national bank doing business under eight local brands,
rather than as a holding company.
Zions Bancorporation's common stock is traded on NASDAQ under the symbol ZION. The company is a
member of the S&P 500 Index and the NASDAQ Financial 100 Index.
