Item 2.02   Results of Operations and Financial Condition Today, November 20, 2025, ESCO Technologies Inc. (the Registrant, or the “Company”) is issuing a press release (furnished as Exhibit 99.1 to this report) announcing its financial and operating results for the fourth quarter and fiscal year ended September 30, 2025. See Item 7.01, Regulation FD Disclosure, below.

Item 5.02   Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers Executive Officers - Long-Term Equity Incentive Awards On November 17, 2025, the Human Resources and Compensation Committee of the Company’s Board of Directors approved the fiscal 2026 awards of time-based Restricted Share Units (RSUs) and Performance Share Units (PSUs) to the Company’s three executive officers and the other participants in the Company’s LTI program, effective November 17, 2025. Other than the share amounts, the terms of the fiscal 2026 RSUs (and future RSUs except to the extent hereafter amended by the HRCC) are substantially similar to those awarded for fiscal 2025, vesting over a period of approximately three years, in three equal portions approximately 12, 24 and 36 months after the grant date; for the fiscal 2026 awards, vesting will occur on the last NYSE trading days in November 2026, 2027 and 2028. The terms of the fiscal 2026 PSUs (and future PSUs except to the extent hereafter amended by the HRCC) are substantially similar to those awarded for fiscal 2025 other than the specific share amounts and performance goals. The fiscal 2026 PSUs will vest after a three-year performance period beginning October 1, 2025 and ending on September 30, 2028, on the last trading day of the month in which the HRCC approves and certifies the extent to which the applicable performance goals have been achieved. Upon vesting, the awards will be converted into a currently undeterminable number of shares of Company common stock, which may be less than or greater than the number of PSUs awarded, within certain specified threshold and maximum limits, depending on the degree to which the Company has achieved one or more specified performance goals. If the performance is less than the threshold goal for a particular performance measure, there will be no payout of that portion of the PSUs dependent on that measure. The performance goals for the fiscal 2026 PSUs are specified Committee-approved targets for EBITDA (60%) and Return on Invested Capital (40%), with the resulting number of shares potentially subject to increase or decrease based on the Company’s Total Shareholder Return (TSR) over the performance period compared to the TSR of the companies in a peer group based on the S&P Small-Cap 600 Industrials Index (rTSR). If the Company’s rTSR is below the 25th percentile or above the 75th percentile, the resulting number of shares will be decreased by 20% or increased by 20%, respectively; if the Company’s rTSR is from the 25th percentile to the 75th percentile, no adjustment will be made. The target number of shares in each RSU and PSU award equals the Committee-approved target values divided by the 15-day average trading price of the Company’s stock. The actual payout of the RSUs and PSUs will be in shares, whose value at the time of payout may be greater or less than the target values. For the executive officers, the numbers of RSUs granted and the PSU threshold, target and maximum numbers of shares payable according to the performance criteria, were as follows: PSU Payout Potential (Shares) Name and Title RSU Number PSU At Threshold At Target At Target Values of RSUs Target Values Performance Performance Maximum as of Granted as of (50% of Performance Grant Date Grant Date Target) (200% of Target) Bryan H.
