Executive Incentive Plans	Executive Incentive Plans Executive Bonus Plan The incentive compensation, including cash payments, election to receive shares of fully vested Class B common stock, and deferred compensation to plan participants, recognized under the amended and restated Bentley Systems, Incorporated Bonus Pool Plan (the “Bonus Plan”) (net of all applicable holdbacks) was $2,393 and $6,367 for the three months ended June 30, 2025 and 2024, respectively, and $4,828 and $13,398 for the six months ended June 30, 2025 and 2024, respectively. Career Stock Program In June 2024, the Sustainability Committee of the Company’s Board of Directors (the “Committee”) established an equity‑based incentive program to compensate a limited set of executives (the “Career Stock Program”) pursuant to which the Company may grant restricted stock units (“RSUs”) awards under the Bentley Systems, Incorporated 2020 Omnibus Incentive Plan (the “2020 Plan”). Under the Career Stock Program, the Committee may from time to time grant RSU awards to program participants, the amount of which is to be determined based upon the Company’s Adjusted operating income less stock-based compensation expense (“AOI less SBC”) (previously titled Adjusted operating income inclusive of stock-based compensation expense (“Adjusted OI w/SBC”)) growth in the year preceding the date of grant (the “Performance Year”) as a percentage of the difference between realized AOI less SBC growth during the Performance Year and an inflation-adjusted target growth level for such Performance Year. Any such awards, if made, would thereafter cliff vest five years following the end of the Performance Year and would otherwise be subject to the terms and conditions of the 2020 Plan. During the three months ended March 31, 2025, the Company granted 28,913 RSUs with a fair value of $1,160 under the Career Stock Program based on the achievement of the performance goals for the year ended December 31, 2024. As of June 30, 2025, there was $1,087 of unrecognized compensation expense related to unvested RSUs under the Career Stock Program, which is expected to be recognized over a weighted average period of approximately 4.5 years.
