Stephenson Stellar Corporation (the “Company”), as an independent nonprofit organization, is exempt from income tax under Internal Revenue Code of 1986 (IRC) Section 501(c)(3) primarily because we are a nonprofit, scientific research organization.

The Company’s primary purpose and programs are to undertake applied scientific research and development activities in the public interest. As reflected in Treasury regulations, rulings and court opinions, the tax law sets out what is required to be and remain exempt under IRC 501(c)(3) as a scientific research organization.
