	Policy or Best Practice				Description and Benefit to Our Stockholders
	Majority of Compensation Performance-Based				For FY 2024, 88% of our CEO’s target total direct compensation (TDC) (base salary + annual cash incentive opportunity + long-term equity incentive opportunity) and an average of 72% of our NEOs’ target TDC was at-risk (all compensation components other than base salary).
	Median Targeting				TDC and the components thereof are generally targeted to be within a competitive range of the median of companies similar in size, scope, and complexity, with variability based on various consideration such as responsibilities, individual performance, tenure, retention, succession, and market factors. Pay decisions are not formulaic and the Committee uses its judgement and consideration of various factors such as individual performance, succession planning, and industry expertise to further determine appropriate pay levels and market positioning.
	Capped Annual Incentive				Annual cash incentive compensation is based primarily on our achievement of performance objectives in the categories of revenue, operating income, cash flow from operating activities, and backlog, with consideration for individual performance, with awards ranging from 0% to a cap of 200% of target.
	Majority Long-Term Equity Incentive Compensation				The majority of our equity-based incentive awards emphasize our long-term performance, with PSUs cliff vesting at the end of three years, subject to achievement of the applicable performance goals. Equity compensation aligns NEO interests with stockholder interests by delivering compensation dependent on our long-term performance and stockholder value creation.
	Rigorous Goal Setting Process				Annual review and approval are completed by the Compensation Committee of the performance goals for the Company (Corporate) and for our business groups. The performance factor used to determine AIP awards is increased or decreased based upon the growth level of the targets from the prior fiscal year.
	No Employment Agreements				Our NEOs are employed at will, and they have no special severance benefits in the absence of a change in control.
	Stock Ownership Guidelines				Our NEOs are required to obtain and maintain shares having a value equal to at least 2x to 6x base salary (based on position). All our NEOs are in compliance with our stock ownership guidelines.
	No Hedging or Pledging				Our insider trading policy prohibits our directors and officers from hedging or pledging our common stock, and all our NEOs are in compliance with that policy.
	Clawback Policy				Our clawback policy provides that in the event we are required to prepare an accounting restatement, we will recover, in accordance with the terms of the policy, compensation received after its effective date by any current or former executive officer that is based wholly or in part upon the attainment of a financial reporting measure.
	No Excise Tax Gross Ups				We do not provide excise tax gross up payments in connection with a change in control.
	Double Trigger Equity Vesting				No equity awards will be accelerated in connection with a change in control unless the NEO’s employment is terminated without cause or the NEO terminates employment for good reason within two years thereof.
	No Repricing/Exchange of Underwater Stock Options				Our Equity Incentive Plan prohibits the repricing/exchange of underwater options without stockholder approval.
	Limited Perquisites				Our NEOs receive limited capped reimbursements for vehicle use, financial planning, tax planning, memberships, and annual physical examinations. These reimbursements are not subject to any tax gross up.
	Independent Oversight				The Compensation Committee is comprised solely of independent directors.
	Independent Expert Advice				Meridian, which has been determined by the Compensation Committee to be independent and free of conflicts of interest, provides the Committee with expert executive compensation advice. Meridian has served as the independent advisor since January 2016.
