Invista Acquires Ashburn Hill, TECGEN® FR Apparel Brands

Wichita, Kan.-based polymer and fiber producer Invista has acquired Greenville-based Ashburn Hill
Corp. including its TECGEN® brands of flame-resistant (FR) apparel and its Angleton, Texas-based
manufacturing operation.

“Invista has an aggressive growth strategy that includes identifying new business
opportunities to allow us to continue building a product portfolio that delivers value to
customers,” said Jeff Brown, executive vice president, Invista Performance Materials. “The TECGEN®
flame resistant brands have quickly gained trust in the marketplace, and by coupling that expertise
with Invista’s existing global workwear capabilities, we have high expectations for the specialized
garment segment.”

Tecgen fiber is produced using a patented carbon technology process that offers advanced
protection against heat and flame. Blends of Tecgen with other inherently FR fibers can be used to
make lightweight, breathable garments that provide a high level of both flame protection and
comfort, according to Invista. The Tecgen brands include: Tecgen Select®, an arc-rated, flame- and
flash-fire-resistant line of garments for manufacturing, transportation, mining, oil and gas, and
energy utility applications; and Tecgen Xtreme®, a National Fire Protection Association
(NFPA)/UL-certified line of lightweight, moisture-repellent clothing for firefighters involved in
wildland and technical rescue operations.

The Tecgen brands will join Invista brands such as CORDURA® in the company’s Performance
Materials business segment, which will provide global resources to enable the brands to expand
their offerings.

Ashburn Hill was incorporated in 2006, and Invista first took an interest in the company in
2008, when Jon Heard left Invista to become its CEO. In the following years, Invista made
investments in Ashburn Hill to help it scale up production.

Heard will continue to head the business under Invista ownership, and Ashburn Hill’s 20
employees at the Greenville administration office and the Angleton manufacturing facility have now
transitioned into Invista.
