(e) On December 16, 2025, the Personnel and Compensation Committee and the Board of Directors of Teledyne Technologies Incorporated ("Teledyne"), with input from Exequity LLP, the Personnel and Compensation Committee's independent compensation consultant, took the following actions with respect to the compensation of Dr. Robert Mehrabian, Executive Chairman of Teledyne, and George C. Bobb III, President and Chief Executive Officer of Teledyne:

(i) The Personnel and Compensation Committee and the Board of Directors approved a Ninth Amended and Restated Employment Agreement with Dr. Mehrabian (the "Ninth Employment Agreement") and, on December 16, 2025, Teledyne and Dr. Mehrabian entered into the Ninth Employment Agreement, which amends and restates Dr. Mehrabian's Eighth Amended and Restated Employment Agreement, dated as of October 24, 2023, as amended on October 22, 2025 (the "Eighth Employment Agreement").

The Ninth Employment Agreement provides that Teledyne shall continue to employ Dr. Mehrabian as Executive Chairman, with primary responsibility to manage the affairs of the Board and to manage and direct mergers and acquisition activities, strategic planning, technology and margin expansion initiatives of Teledyne. The term of the Ninth Employment Agreement continues through December 31, 2028.

The Mehrabian Employment Agreement further provides for the following, among other things: • Base Salary: Dr. Mehrabian's base salary shall be $1,300,000 effective as of January 1, 2026, subject to future annual increases at the discretion of the Committee. • AIP: As was also provided in the Eighth Employment Agreement, Dr. Mehrabian shall participate in Teledyne's Annual Incentive Plan (AIP) with a target opportunity of 150% of base salary.

• Performance Plan: Starting in 2026, Dr. Mehrabian will participate at a target opportunity of 110% of base salary.

• Restricted Stock: Starting in 2026, Dr. Mehrabian shall participate in the performance-based restricted stock award program with annual grants equal to at least 110% of base salary as of the date of the grant subject to meeting targets set forth in the restricted stock award.

In addition, Dr. Mehrabian will receive a one-time special retention performance-based restricted stock award grant of $3.3 million at the same time as annual grants of restricted stock are made in 2026. This additional, one-time grant is subject to meeting targets set forth in the restricted stock award. • Stock Options: With respect to options granted to Dr. Mehrabian beginning in 2026 and thereafter, if any, the Ninth Employment Agreement provides that Dr. Mehrabian's stock option grants will have a fair value as of the grant date equal to 110% of base salary. As was also provided in the Eighth Employment Agreement, the Ninth Employment Agreement provides that (i) in the event of Dr. Mehrabian's separation of service for any reason other than death, outstanding stock options shall continue to vest and the right of Dr. Mehrabian to exercise vested stock options, when and as vested, shall continue and (ii) in the event of the death of Dr.

Mehrabian, all outstanding options shall vest in full and the right of Dr. Mehrabian's beneficiary to exercise the stock options shall terminate upon the expiration of twelve months from the date of Dr. Mehrabian's death; provided that in no event may such stock options be exercised after the expiration of any applicable option period.

• Employee Benefits: Dr. Mehrabian is entitled to participate in each qualified, non-qualified and supplemental employee benefit, executive benefit, fringe benefit and perquisite plan, policy or arrangement of Teledyne applicable to executive level employees. This includes the provision of risk-based, business related and personal security services, as determined to be appropriate by Teledyne's security team, based on Dr. Mehrabian's executive position and profile.

• Supplemental Pension Benefit: As was also provided in the Eighth Employment Agreement, with respect to Dr. Mehrabian's Non-Qualified Pension Benefit, which provides for payments supplemental to any accrued pension under Teledyne's qualified pension plan equal to 50% of his base salary for ten years following Dr. Mehrabian's retirement, the Mehrabian Employment Agreement provides that the base salary rates to be used for calculating the payments shall be the rates in effect for 2018 (which was $995,000). As was also provided in the Eighth Employment Agreement, the Ninth Employment Agreement further provides that Teledyne will pay to Dr. Mehrabian (or his designee in the event of death) any unpaid amounts under the Non-Qualified Pension Benefit in a single lump sum payment within sixty (60) days following the date of Dr. Mehrabian's death or disability. In addition, Dr. Mehrabian may request a payment under the Non-Qualified Pension Benefit in the event of an unforeseeable emergency as such term is defined under Section 409A of the Internal Revenue Code.

• Post-Retirement Medical Coverage: As was also provided in the Eighth Employment Agreement, commencing on Dr. Mehrabian's separation from service (for any reason) and continuing for the longer to live of Dr. Mehrabian and his spouse, Dr. Mehrabian and his spouse shall be deemed participants in Teledyne's medical benefit plan offered to all employees of Teledyne and be deemed to be eligible to receive the benefits under the medical plan. Dr. Mehrabian shall be charged for such deemed participation at a rate equal to the monthly rate the medical plan charges former participants and spouses eligible for continuation coverage under COBRA, plus the rate payable by the employer, as each such COBRA rate is adjusted from time to time.

On December 16, 2025, the Board of Directors of Teledyne, upon the recommendation of the Nominating and Governance Committee of the Board of Directors, approved a revised Sixth Amended and Restated Bylaws (the "Restated Bylaws") in connection with permitting stockholders who hold, in the aggregate, at least 25% of the combined voting power of all outstanding voting securities of Teledyne to call a special meeting of stockholders.
