TriMas Corporation ("TriMas" or the "Company"), and its consolidated subsidiaries, is a diversified industrial manufacturer of products for customers primarily in the consumer products, aerospace and industrial end markets.

In the first quarter of 2019, TriMas began reporting its Stanton, California and Tolleson, Arizona machined components operations in its Specialty Products reportable segment. They were previously included in the Company's Aerospace reportable segment. This modification was made in connection with an organizational change of leadership responsibilities, allowing the Company to better leverage the machining competencies and resources of these operations with the other businesses within the Specialty Products reportable segment.

On December 20, 2019, the Company completed the previously announced sale of its Lamons business (“Lamons”), a transaction entered into with an investment fund sponsored by First Reserve on November 1, 2019. Lamons was sold for approximately $135 million in cash, subject to customary post-closing adjustments. The financial results of Lamons were previously reported within the Company's Specialty Products reportable segment, and are presented as discontinued operations for all periods presented in the financial statements attached hereto.

See Note 19, "Segment Information," for further information on each of the Company's reportable segments.
