Director Elections
Election of Directors
CEO and director since 2017; WMS 3-year TSR of +36.0% outperforms the peer group median of +34.6% by +1.4pp, well below the 65pp underperformance threshold required to trigger a vote against, and no other policy flags apply.
Independent director since 2020 with strong executive and industrial leadership credentials; TSR underperformance trigger does not apply (3-year gap vs. peer median is only -1.4pp against WMS, which outperforms), and no overboarding, attendance, or independence concerns are identified.
Independent director since 2018 with legal and public policy expertise; WMS 3-year TSR does not breach the peer-group underperformance threshold, and all board meeting attendance and independence requirements are met.
Independent Board Chair since 2008 with deep private equity and banking background; despite long tenure, WMS 3-year TSR of +36.0% versus peer median of +34.6% shows only +1.4pp outperformance, and the TSR underperformance trigger is not met, so no vote-against flag applies.
Independent director since 2014 serving on Audit and Governance committees; WMS stock performance relative to peers does not breach the underperformance threshold, attendance is satisfactory, and no independence or overboarding concerns are present.
Independent director since 2013 with extensive CEO and engineering background; TSR trigger is not met, all meetings were attended at or above the 75% threshold, and no other policy flags apply.
Independent director since 2022 with CFO and CPA credentials qualifying her as an audit committee financial expert; joined within the past four years and the TSR trigger does not apply given WMS's peer-relative performance, with no other concerns identified.
Independent director since 2019 serving as Audit Committee Chair with CPA and CEO background; WMS 3-year TSR does not breach the peer-group underperformance threshold, and no overboarding, attendance, or independence concerns are identified.
Independent director since 2021 with public and private equity investment expertise; joined within four years and the TSR trigger is not met given WMS's performance relative to peers, with no other policy flags triggered.
All nine director nominees receive a FOR vote. WMS's 3-year total shareholder return of +36.0% outperforms the company-disclosed compensation peer group median of +34.6% by +1.4 percentage points, well below the 65-percentage-point underperformance threshold required to trigger a vote against any director under the strong-positive-TSR band. No directors are overboarded, no attendance issues were disclosed, all independent directors serve only on committees appropriate to their independence status, and no familial relationships with senior management were identified.
Say on Pay
✓ FORCEO
D. Scott Barbour
Total Comp
$7,398,322
Prior Support
88%%
CEO D. Scott Barbour received total compensation of $9,780,935 in fiscal year 2026, which reflects a strong pay-for-performance year: the annual cash bonus paid out at 169% of target driven by Adjusted EBITDA of $963 million (above target) and net sales growth of 5%, while the completed three-year performance stock award cycle paid out at 200% of target based on cash flow from operations and return on invested capital that both exceeded maximum thresholds. The compensation program structure is sound — roughly 86% of the CEO's total pay is variable (equity awards plus performance-linked bonus), well above the 50-60% minimum the policy requires for senior executives, with fixed base salary of $1,050,000 representing only about 10.7% of total compensation. Prior-year Say on Pay received 88% shareholder support (above the 70% threshold that would require corrective action), a meaningful clawback policy is in place, and stock ownership guidelines with retention requirements are enforced, so no policy triggers for a vote against are present.
Auditor Ratification
✓ FORAuditor
Deloitte & Touche LLP
Tenure
23 yrs
Audit Fees
$3,544,000
Non-Audit Fees
$146,000
Deloitte has served as WMS's auditor since 2003, giving it approximately 23 years of tenure — below the 25-year threshold that would trigger a concern. Non-audit fees (audit-related fees of $125,000 plus tax fees of $17,000 plus other fees of $4,000, totaling $146,000) represent only about 4.1% of audit fees of $3,544,000, well within the 50% limit. Deloitte is a Big Four firm appropriate for WMS's roughly $10 billion market cap, and no material financial restatements were identified.
Overall Assessment
The 2026 Advanced Drainage Systems annual meeting presents three standard proposals: election of nine directors, ratification of Deloitte & Touche LLP as auditor, and an advisory vote on executive compensation. All three proposals receive a FOR vote — the director slate shows no TSR underperformance, overboarding, or independence concerns; the auditor's non-audit fees are well within policy limits and tenure is below the 25-year threshold; and the executive pay program is heavily performance-linked with strong prior-year shareholder support and above-target payouts that were earned through genuine financial outperformance.
