Section 1 – Registrant’s Business and Operations

Item 1.01 Entry into a Material Definitive Agreement.

On October 22, 2025, Hexcel Corporation (the “Company”) entered into a master confirmation (each, a “Master Confirmation”) and supplemental confirmation (together with the related Master Confirmation, collectively, the “ASR Agreements”), with each of Bank of America, N.A. (“Bank of America”) and Goldman Sachs & Co. LLC (together with Bank of America, the “Counterparties”). Under the ASR Agreements, the Company will repurchase an aggregate of $350 million of the Company’s common stock, $0.01 par value per share (such stock, the “Common Stock,” and such transaction, the “ASR”) as part of a new share repurchase program (the “2025 Share Repurchase Program”) approved by the Company’s Board of Directors (the “Board”) on October 22, 2025. Pursuant to the ASR Agreements, the Company will make payments in an aggregate amount of $350 million to the Counterparties on October 24, 2025, and the Company will receive on October 24, 2025 the initial deliveries of approximately 80% of the total shares that are expected to be repurchased under the ASR. The final number of shares to be repurchased will be based on the average of the daily volume-weighted average prices of the Company’s common stock during the term of the ASR Agreements, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR Agreements. Upon final settlement of the ASR, under certain circumstances, each of the Counterparties may be required to deliver additional shares of common stock, or the Company may be required to deliver shares of common stock or to make a cash payment, at its election, to the Counterparties. The final settlement of each transaction under the ASR Agreements is scheduled to occur no later than the first quarter of 2026 and in each case may be accelerated at the option of the applicable Counterparty.

Each of the ASR Agreements contains customary terms for these types of transactions, including, among others, the mechanisms to determine the number of shares or the amount of cash that will be delivered at settlement, the required timing of delivery upon settlement, the specific circumstances under which adjustments may be made to the transactions, the specific circumstances under which the transactions may be cancelled prior to the scheduled maturity and various acknowledgments, representations and warranties made by the Company and the Counterparties, as applicable, to one another.

The form of the ASR Agreements is included herein as Exhibit 10.1 and is incorporated herein by reference. The foregoing description of the ASR Agreements is a summary and is qualified in its entirety by reference to the form of the ASR Agreements.

Section 2 – Financial information

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

As previously reported, on April 25, 2023, the Company entered into a senior unsecured revolving credit agreement (the “Credit Agreement”) providing for a $750 million revolving credit facility (the “Revolver”). On October 21, 2025, the Company provided notice to the lenders pursuant to the Credit Agreement to borrow $350 million under the Revolver to fund the initial settlement of the ASR. A full description of the Revolver and the Credit Agreement is set forth under Item 1.01 in the Company’s Current Report on Form 8-K filed on April 28, 2023 (the “Prior 8-K”), which description is incorporated herein by reference. In addition, the Credit Agreement was filed as Exhibit 10.1 to the Prior 8-K and is incorporated herein by reference.

Section 8 – Other Events

Item 8.01 Other Events.

On October 22, 2025, the Board approved an additional $600 million authorization to purchase shares of Common Stock under the 2025 Share Repurchase Program. This amount is in addition to the amount that currently remains available for repurchases under the prior share repurchase program approved by the Board in February 2024 (together with the 2025 Share Repurchase Program, the “Share Repurchase Programs”). The purchases of such shares under the 2025 Share Repurchase Program are anticipated to be made in open market transactions, block transactions, privately negotiated purchase transactions or other purchase techniques at the discretion of

management based upon consideration of market, business, legal, accounting, and other factors. In addition, the Company may establish one or more trading plans pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, or enter into arrangements with brokers or other third parties for accelerated purchases of Common Stock. After giving effect to the ASR, the aggregate remaining authorization under the Share Repurchase Programs is approximately $384 million. There is no guarantee as to the exact number of shares of Common Stock that the Company may repurchase under the Share Repurchase Programs.
