Long‑Term Incentives (LTI) and Grants

ElementTarget/Structure2024 Grants2025 UpdatesVesting/Performance
LTI target as % base (CEO)500% of base for 2025; program split equally in value among options, RSUs, PSUs No regular 2024 LTI; sign‑on RSUs only CEO LTI target set at 500% of base starting 2025 Options: 10‑yr term, 3‑yr ratable vest; RSUs: typically 100% cliff at 3 years; PSUs: 3‑yr performance
Sign‑on RSU (appointment)$3,000,000 grant date fair value on 7/15/2024 Vests 100% on 7/15/2027; no dividend equivalents
Special RSU (Feb 2025)$1,000,000 grant date fair value approved 2/28/2025 Vests 100% on 2/28/2028, continuous employment required
PSU design (2024 cycle)Relative TSR vs peer group or EVA bonus multiple, whichever yields higher payout Targets established for other NEOs in Feb 2024; CEO had no 2024 PSU grant 2025 LTI expected to include PSUs per equal‑split design Threshold 25% (TSR ≥33rd percentile or EVA multiple ≥0.5x); Target 100% (TSR ≥50th percentile or EVA multiple ≥1.0x); Max 200% (TSR ≥75th percentile or EVA multiple ≥2.0x)

Compensation structure calibration:

  • Committee targets generally 80–110% of market 50th percentile for LTI to ensure competitiveness (with Willis Towers Watson input) .

Equity Ownership & Alignment

ItemDetail
Total beneficial ownership (as of Mar 10, 2025)0 shares; “less than 1%” of class
Unvested RSUs at 12/31/202420,401 RSUs; FMV $2,338,975
2025 special RSU grant$1,000,000 grant; share count set by avg. high/low on 2/28/2025
Options/PSUs outstandingNone reported for CEO in 2024 SCT tables
Pledging/hedgingProhibited; none of directors/executives currently pledge shares; pre‑notice required before any pledging
ClawbackEquity awards, shares issued, and profits on sale subject to clawback per policy
Stock ownership guidelinesMust retain 100% of net‑after‑tax vested shares until value reaches 6x annual base salary (PEO); 3x for certain other officers; 5x for directors

Implications for selling pressure and alignment:

  • CEO currently holds no vested shares and must retain future vested shares toward a 6x‑salary threshold, limiting discretionary selling until guideline is met .
  • Sign‑on RSUs vest in 2027 and special RSUs in 2028, concentrating value in unvested equity and supporting retention .

Employment Terms

TopicKey Terms
Employment agreementsNo separate employment agreements; executives receive offer letters outlining principal terms
AIP/QIP upon terminationAIP/QIP Final Award payable upon death, disability, Normal Retirement; certain “reduction‑in‑force” cases pay banked amounts only
Equity upon terminationDeath: unvested options/RSUs/PSUs vest (PSUs at target). Normal Retirement: prorated vesting and PSU eligibility based on actual results. Without Cause: limited prorated vesting of next tranche of options
Change‑in‑control (CIC) frameworkIf awards not assumed/replaced: full vest at CIC (performance awards at level achieved). If assumed/replaced: no acceleration except pro‑rated double‑trigger vesting on termination without Cause/for Good Reason within 24 months post‑CIC; AIP similarly pro‑rated and fixed based on performance to CIC
CIC / Cause / Good Reason definitionsCIC includes sale of substantially all assets, ≥50% equity change, reorganization/merger, liquidation, board turnover; “Cause” and “Good Reason” defined with specificity (e.g., felony, material duty change, salary/bonus reduction, >50‑mile relocation)
280G parachute capAwards limited as necessary to avoid excise tax under IRC §§280G/4999; no gross‑ups disclosed

Compensation Structure Analysis

  • Shift/mix: 2024 compensation was cash plus a large sign‑on RSU ($3.0M) with no regular LTI, transitioning to a 2025 LTI target of 500% of salary split equally among options, RSUs, and PSUs—raising equity‑at‑risk exposure from 2025 onward .
  • Performance metrics: AIP requires at least one gating metric (TSR, EVA, or SG&A) to be met; PSUs pay on Relative TSR or EVA multiple, reinforcing return and capital discipline; 2022–2024 PSU payout at 185.6% underscores emphasis on TSR .
  • Cash vs equity: 2024 non‑equity incentive (AIP+QIP) totaled $716,114; equity was dominated by the 3‑year cliff sign‑on RSU; 2025 plan re‑balances toward a standard three‑part LTI with multi‑year horizons .
  • Governance: Strong policies on ownership (6x salary), no hedging/pledging, and clawbacks limit misalignment and near‑term selling .

Say‑On‑Pay, Peer Group, and Committee Practices

  • Market calibration and independence: Committee targets LTI competitiveness at 80–110% of market 50th percentile, with Willis Towers Watson as independent advisor .
  • Clawback/insider policy: Enhanced clawback and anti‑hedging/pledging policies are in place .
  • (Proxy does not disclose say‑on‑pay outcomes in cited sections; omitted.)

Investment Implications

  • Alignment and retention: Zero current ownership but stringent 6x‑salary ownership guideline plus large unvested RSUs (vesting 2027 and 2028) create strong retention incentives and constrain near‑term selling, reducing insider‑selling overhang risk beyond tax withholds .
  • Pay‑for‑performance: AIP gating metrics and PSU design focused on Relative TSR/EVA should keep incentives tied to value creation; historical PSU over‑target payout (185.6% for 2022–2024) signals that TSR outperformance does translate into realized comp .
  • Change‑in‑control economics: Double‑trigger, pro‑rated vesting when awards are assumed and parachute caps (no gross‑ups) reduce windfall risk; CEO’s modeled CIC scenarios show equity‑driven payouts with limited cash components (AIP), consistent with best practices .
  • Execution risk: CEO brings global chemicals leadership experience (Mitsubishi Chemical Group, Roquette, Dow Corning, Avantor); the 2025 LTI target (500% of salary) heightens performance exposure and alignment as he executes strategy under Westlake’s capital‑discipline framework .
