Executive Compensation Highlights

The Company’s executive compensation program is designed to provide a competitive compensation package that will attract, retain and motivate our executives to drive the Company’s success through high performance and innovation, to link our executives’ compensation to short- and long-term performance of the Company and to align our executives’ compensation with the interests of our stockholders. To do this, we:

•Provide our NEOs with a fixed level of cash compensation in the form of base salary that is consistent with their skill level, experience, knowledge, length of service with the Company and the level of responsibility and complexity of their position, and is generally targeted at the competitive market median of our peer group;

•Provide an annual short-term incentive (“STI”) program cash incentive award with the objective of providing a competitive level of performance-based annual compensation at the target achievement level, with the opportunity for incentive compensation above target if stretch performance is achieved, and with metrics that focus on key measures of success that the executive team is able to impact over an annual timeframe; and

•Provide a long-term incentive (“LTI”) plan award that is the largest component of our NEOs’ target direct total compensation and is designed to align management’s performance incentives and pay outcomes with the interests of our stockholders by linking executive pay to stockholder value creation as the award consists of a combination of time-based restricted stock units (“RSUs”) that vest ratably over a three-year period and performance-based RSUs (“PSUs”) that use (i) organic sales growth as the performance metric and (ii) relative total stockholder return (“rTSR”) versus our peer group as the performance metric, each representing one-third of the award.

Below are several of actions that the Compensation and Organization Committee (the “Compensation Committee”) took in 2025 to ensure alignment to market-based best practices and policies:

•Approved short-term incentive payouts based on achievement against adjusted targets established early in April 2025 to anticipate the impact of tariffs on the business, and used negative discretion to reduce the payout factor in recognition that the tariffs had not materially impacted the company.

•Extended the post-vest holding period from six to twelve months for the rTSR PSUs granted in 2025.

•Recommended to the independent members of the Board the compensation arrangements for our new President and Chief Executive Officer (the “CEO”) and related retirement transition arrangements for our outgoing CEO.

•Awarded a special recognition cash bonus to one of our NEOs for his exemplary work in completing one of our acquisitions.

•Granted special stock-based incentive awards and cash sign-on bonus to one of our NEOs in connection with her hiring.

Below are some highlights of our executive compensation program:

Last year’s “say-on-pay” proposal regarding the compensation awarded to NEOs received the support of approximately 98% of votes cast by our stockholders (excluding abstentions and broker non-votes). The Compensation Committee and the Board take into account results of the “say-on-pay” vote as they consider the design of the executive compensation program and policies. Based on the voting results, we believe our overall executive compensation program is aligned with the interests of our stockholders and no changes were made to the executive compensation program in director response to the “say-on-pay” voting results in 2025.
