FOR IMMEDIATE RELEASE

TAT Technologies Expands Strategic Relationship with Honeywell Aerospace,

Strengthening its Position in the APU Aftermarket

Agreement Designates TAT as Sole* Authorized Distributor of GTCP 331-200/250 APU Spare Parts and

extends MRO licenses period for this platform until 2036

Charlotte, NC, July 14, 2026 - TAT Technologies Ltd. (Nasdaq: TATT) (TASE: TATT) (“TAT” or the “Company”), today announced an expansion of its relationship with Honeywell Aerospace (Nasdaq: HONA), under which TAT will become the sole global authorized distributor of spare parts for the 331-200/250 auxiliary power unit (APU) platform. As part of this agreement, the company also signed an extension for its MRO licenses for this platform until 2036 and acquired three Honeywell Aerospace 131-9A APUs to expand its trading and leasing business. This agreement positions TAT as the leading global provider of MRO services and aftermarket parts support for the platform.

For operators, lessors, and MRO providers maintaining aircraft on this platform, the result is a single, trusted source for both service and parts — reducing the coordination typically required across multiple vendors and supporting faster turnarounds when aircraft need a reliable and accurate return to service commitment. This agreement deepens TAT's relationship with its global customer base and positions the Company to build new relationships across the broader operator community on this platform.

Mr. Igal Zamir, TAT's CEO and President, commented, "Our relationship with Honeywell Aerospace has been one of the most important partnerships in TAT's history, and this agreement reflects the continued strength and trust we've built together over the past several years. Honeywell Aerospace has been an outstanding partner to TAT, and this expansion is a meaningful vote of confidence in our team and the track record we've built together."

"This agreement makes TAT the sole parts distributor of the APU 200 and APU 250 platforms, adding a distribution capability to our business that complements the MRO services we've long provided — allowing us to support these platforms across their full lifecycle, from parts supply through repair and return. Bringing parts and service together under one roof means faster turnaround and the kind of responsive support our customers have come to expect from TAT. We're proud of what this relationship has built so far, and even more excited about where it's headed."

“Honeywell Aerospace remains committed to strengthening the global ecosystem that supports our APU customers,” said Brandie Maxwell, VP Sales Americas Aftermarket of Honeywell Aerospace. “TAT has consistently demonstrated the technical excellence, and responsiveness operators expect, and expanding their role as our sole authorized distributor reinforces our focus on long‑term fleet support, reliability, and customer value.”

* Excluding Africa prior to 2030 and excluding direct distribution to non-aftermarket original equipment manufacturers (OEMs).
