TAT Technologies Reports First Quarter 2026 Results

Backlog and Long-Term Agreements Increase to ~$580 Million on Strong Demand

Charlotte, N.C, May 20, 2026 - TAT Technologies Ltd. (NASDAQ and TASE: “TATT”) (“TAT” or the “Company”) a leading provider of products and services to the commercial and military aerospace and ground defense industries, today reported its unaudited results for the three-month period ended March 31, 2026.

Financial highlights for the first quarter of 2026:

•	Revenues were $41.1 million; a slight decrease of 2.4% compared to $42.1 million in the first quarter of 2025, driven primarily by component part shortages and delayed deliveries from certain OEM suppliers.

•	Gross profit remained stable at $10.0 million. Gross margin improved by 80 basis points to 24.4% of revenues, compared to 23.6% of revenues in the first quarter of 2025.

•	Operating income was $3.0 million, a decrease from $4.2 million in the first quarter of 2025, reflecting a margin of 7.3% versus 9.9% in the first quarter of 2025.

•	Net income totaled $3.4 million, a slight decrease compared to $3.8 million in the first quarter of 2025.

•	Adjusted EBITDA was $4.9 million, representing 11.8% of revenues, a decrease from $5.7 million representing 13.6% of revenues in the first quarter of 2025.

•	Operating cash flow for the quarter was positive $1.9 million compared to negative $(5.0) million used in operating activities in the first quarter of 2025, reflecting a significant improvement in cash generation.

Mr. Igal Zamir, TAT's CEO and President, commented: "TAT Technologies entered 2026 with a robust operational foundation, and the record customer demand in the first quarter reinforced our confidence in the trajectory we are on. Demand for our services has never been stronger, and the value of our long-term agreements and backlog reached an all-time high, growing to approximately $580 million at the end of Q1, reflecting new contract wins and exceptionally strong customer intake across all four of our service lines."

As opposed to this strong momentum entering the year, and as previously communicated, we experienced some supply chain disruptions that affected the results of the first quarter. These distruptions were triggered by certain OEM suppliers, leading to delays in finish goods and deliveries. Primarily as a result of these delays, our revenue slightly declined YoY, not fully utilizing our growing backlog. We expect this obstacle to be resolved in the next few months, allowing TAT the continued growth trajectory we started last year.

"As we look ahead through the rest of 2026, we are confident in the fundamentals of the business. Demand is at an all-time high and our record backlog provides strong revenue expectations. Subject to the anticipated resolution of our recent supply chain disruptions, we expect our growth trajectory will resume in the second quarter and the second half of the year, driven primarily by stronger demand and record backlog. We remain well-positioned to deliver growth and long-term value for our shareholders," concluded Mr. Zamir.

Non-GAAP Financial Measures

To supplement the consolidated financial statements presented in accordance with GAAP, the Company also presents Adjusted EBITDA. The adjustments to the Company’s GAAP results are made with the intent of providing both management and investors with a more complete understanding of the Company’s underlying operational results, trends and performance. Adjusted EBITDA is calculated as net income excluding the impact of: the Company's share in results of affiliated companies, share-based compensation, taxes on income, financial (expenses) income, net, and depreciation and amortization. Adjusted EBITDA, however, should not be considered as an alternative to net income and operating income for the period and may not be indicative of the historic operating results of the Company; nor is it meant to be predictive of potential future results. Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles and may not be comparable to other similarly titled measures for other companies. See reconciliation of Adjusted EBITDA below.

Investor Call Information

TAT Technologies will host an earnings webcast and conference call today, May 20, 2026, at 8:00 a.m. Eastern Time to discuss first quarter results. Investors may register using the link below or by visiting the Company's website.
