The Kuskokwim Corporation's 2,903 shareholders (as of May 2007), with 1,827 class B and over 1,200 class A shareholders (some shareholders hold class B and class A stock through inheritance) whom are bound together by a tradition rich in culture and history.

These shareholders consist primarily of Yupik Eskimos and Athabaskan Indians that are residents of, or descendants of residents, of ten villages along the Kuskokwim River.

Original shareholders that were born later than December 18, 1971 were included in the Alaska Native Claims Settlement Act enrollment. Later, TKC shareholders voted to include their children and began enrolling eligible children born after December 18, 1971 as Class B shareholders.

TKC was among the first native corporations to take this step and enroll shareholder children born post-ANCSA.
