Equity Ownership & Alignment

Date (Reference)Beneficial Ownership (Shares)Ownership % of OutstandingComponents/Notes

Additional alignment:

  • Pledging/Hedging: Policy prohibits short-selling, options/speculative trading, hedging/monetizations, and pledging company stock as collateral; margin accounts disallowed .
  • Trading Controls: Strict trading windows, preclearance for access insiders, and 10b5-1 cooling-off (90–120 days) for executives/directors .
  • Ownership Guidelines: Not disclosed.
  • Stock Ownership Guidelines compliance: Not disclosed.

Employment Terms

  • Employment Agreements: Post-Closing, SLXN “has entered or will enter into employment agreements” with NEOs; detailed severance/change-of-control terms for Dr. Shirvan not disclosed .
  • Insider Trading Policy: Enforced trading windows, preclearance, and restrictions; includes prohibition on speculative trades, hedging, and pledging; outlines post-termination trading blackout related to material non-public information .
  • Clawback: Company-wide clawback under SEC/Nasdaq rules, non-indemnifiable and additive to other recoupment rights .

Performance & Track Record

  • Program data: Phase 2 trial of first-generation siRNA (LODER) in LAPC showed a 9.3-month numerical median OS advantage (22.7 vs 13.4 months) in KRAS G12D/V subset; not powered for statistical significance (HR=0.59; p=0.39), safety acceptable, and intratumoral delivery showed no systemic exposure in plasma .
  • Platform advancement: SIL204 preclinical data show broad KRAS silencing, tumor growth inhibition, and reduced metastatic burden; improved stability and potential systemic viability in models .
  • Regulatory path: BfArM (Germany) agreed in principle to Phase 2/3 design; SLXN plans CTA in Q1/H1 2026 and Phase 2/3 initiation in H1 2026 .
  • Company context: SLXN is pre-revenue and requires ongoing financing; equity pool increase and authorized capital actions support talent incentives and listing compliance .

Investment Implications

  • Pay mix and retention: 2024 compensation is heavily equity-based (>$1.0M stock awards) versus 2023, indicating alignment with value creation and retention via RSUs/options; accelerated vesting at the Business Combination could create periodic liquidity but trading is constrained by windows and 10b5-1 plans .
  • Alignment safeguards: Prohibitions on hedging/pledging and a robust clawback reduce misalignment and reputational risk around compensation .
  • Execution risk: SLXN’s pre-revenue status and financing needs increase reliance on clinical/regulatory milestones; performance compensation is implicitly tied to program progress rather than near-term financial metrics .
  • Insider selling pressure: No Form 4 transaction data was found in company filings; preclearance, windows, and cooling-off rules restrict opportunistic sales, moderating short-term selling pressure; monitor future Form 4s for any 10b5-1 activity .
