Fixed Compensation
- No specific base salary, target bonus %, or actual bonus amounts for Holly Kordasiewicz were disclosed in Ionis’ most recent proxy; Ionis generally reports detailed compensation for named executive officers, and the filing indicates executive officers participate in the Severance Benefit Plan rather than individual employment contracts .
Executive officers “do not have employment contracts with us; however, they are entitled to participate in our Severance Benefit Plan” .
Performance Compensation
- Company policy for executive officers’ long‑term incentives (relevant to the EVP role Holly will assume):
- Performance RSUs (PRSUs) have a single vesting at the end of 3 years; maximum payout requires a higher relative TSR percentile rank increased from 75th to 90th percentile starting with 2023 grants .
- For “other executive officers,” PRSUs account for 20% of annual total equity awards; options and PRSUs are treated as performance‑based compensation .
- Minimum vesting period for equity awards is 12 months .
| Metric | Weighting | Target | Actual/Payout | Vesting |
|---|---|---|---|---|
| Relative TSR vs peer group (PRSUs) | 20% of annual total equity awards for other executive officers | Target level set by Compensation Committee (not publicly quantified) | Maximum payout threshold increased to 90th percentile (from 75th) in 2023+ grants | Single vest at end of three‑year performance period . |
Note: No Holly‑specific annual grant counts or payouts were disclosed in filings; the table reflects Ionis’ framework applicable to executive officers .
Equity Ownership & Alignment

- Clawback: Executive clawback policy aligned with SEC and Nasdaq 2023 rules; applies to Section 16 officers .
| Alignment Mechanism | Policy | Status/Notes |
|---|---|---|
| Ownership guideline | 2x base salary for other executive officers | Company disclosed compliance by executive officers with named exceptions (not listing Holly) . |
| Rule 10b5‑1 trading program | Required for executive officers and vice presidents (modified to comply with 2022 SEC rules) | Limits discretionary trading; helps manage selling pressure . |
| Hedging/pledging | Prohibited for directors and employees | Reduces misalignment/credit risk from pledging . |

Performance & Track Record
- Positive pivotal study: Led Ionis’ Alexander disease program, with zilganersen showing unprecedented disease‑modifying impact; NDA submission targeted for Q1 2026 .
- Portfolio leadership: Oversees Ionis’ neurology pipeline including Angelman syndrome (ION582 phase 3 REVEAL ongoing), Alzheimer’s (BIIB080), prion disease, and MSA; pediatric neurology focus with upcoming readouts and first independent neurology launch planned in 2026 .
- Partnered program contributions: Integral role in Biogen‑partnered QALSODY (tofersen) and IONIS‑MAPTRx .
- Publications: Co‑authored 2025 eLife article on ASO strategy in 22q11.2 deletion syndrome (Ionis affiliation) .
Investment Implications
- Compensation alignment: Ionis’ framework (3‑year PRSUs with elevated TSR thresholds, clawback, ownership guidelines, no hedging/pledging) suggests high alignment of executive incentives with long‑term TSR, which will apply to Kordasiewicz as EVP/CDO .
- Retention and change‑in‑control economics: Robust severance benefits with double‑trigger equity acceleration and meaningful health coverage reduce retention risk during strategic transitions; lack of gross‑ups is shareholder‑friendly .
- Insider selling pressure: Mandatory 10b5‑1 plan usage for executive officers/VPs, combined with anti‑hedging/pledging policies, limits opportunistic selling pressure and alignment dilution .
- Execution signal: Track record of advancing first‑in‑class neurology programs (zilganersen pivotal success; Angelman phase 3) and partnered assets indicates strong execution capabilities as she steps into the CDO role—an incremental positive for pipeline value creation .
