Dear Patrick,

On behalf of Howmet Aerospace, I am pleased to offer you the position of Executive Vice President and Chief Financial Officer reporting to John Plant, Chairman & CEO, based in Pittsburgh, PA. Our Pittsburgh office currently operates on a hybrid schedule, and you will be expected to work from the office on at least Mondays, Wednesdays, and Thursdays, and any other additional weekdays as may be required.

The total compensation package, subject to approval by the Compensation and Benefits Committee of the Board of Directors, includes annual base salary and substantial additional long-term compensation opportunities as summarized below.

Salary:

Your annual base salary will be $700,000 paid on a monthly basis in accordance with the Company’s normal payroll practices, and subject to all applicable taxes and withholdings. Salary reviews typically take place on an annual basis with increases effective March 1^st.

Incentive Compensation:

You will be eligible for target annual Incentive Compensation of 100% of your base salary, or $700,000 for a full year, if targets are met. Actual payouts could be higher or lower than target depending on individual and business performance.

Sign-On Cash Payments:

You will receive a sign-on cash bonus with a total value of $800,000 as soon as administratively feasible after your start date, less any applicable tax withholding. Should you voluntarily terminate your employment with the Howmet for any reason in the first 24 months after your start date, you agree to reimburse the company for your sign-on cash payment.

Annual Equity Awards:

Each year you will be eligible for an annual equity award, typically granted in February, based on the guidelines for executives at your level.

For your 2026 annual award, you will receive an equity award of $2,000,000 granted as 40% time-vested restricted stock units and 60% performance-based restricted stock units. The award will vest 3 years from the date of grant, subject to your continued employment through the vesting date.

However, if you are involuntarily terminated without cause within five years of your date of hire, any outstanding unvested annual equity awards will not be forfeited but will continue to vest on the original vesting schedule.

Equity Ownership Requirements:

Consistent with Company’s efforts to align the interests of its senior leadership with the interests of shareholders, the Company has adopted equity ownership requirements for senior executives. You will be subject to these requirements, currently 3.0 times base salary for executives at your level, during your employment with the Company. Until equity ownership requirements are met, you are required to retain 50% of shares acquired upon vesting of restricted stock units and performance-based restricted stock units or upon exercise of stock options, after deducting those used to pay for applicable taxes and/or the exercise price.
