Election of Three (3) Class I Directors
Mr. Arbuckle joined the board in January 2026, well within the 24-month new-director exemption from the TSR trigger, and brings over 30 years of highly relevant biopharmaceutical commercial and leadership experience; no overboarding, attendance, independence, or other policy concerns apply.
As CEO and director since 2021, Dr. Greenstreet is subject to the TSR trigger, but Alnylam's 3-year price return of +69.3% is strong positive and the gap versus the company-disclosed peer group median is +35.8 percentage points — well below the 65-percentage-point underperformance threshold required to fire the trigger — so no TSR concern applies; no other policy flags are present.
Dr. Sigal has served since 2022 and Alnylam's 3-year stock return of +69.3% outperforms the company-disclosed peer group median by +35.8 percentage points, far short of the 65-percentage-point threshold needed to trigger a negative vote; no overboarding, attendance, independence, or qualification concerns are present.
All three Class I nominees — Stuart Arbuckle (new director, exempt from TSR trigger), CEO Yvonne Greenstreet, and Elliott Sigal — receive a FOR vote. Alnylam's 3-year total shareholder return of +69.3% outperforms its company-disclosed compensation peer group median of +33.5% by approximately +35.8 percentage points, comfortably below the 65-percentage-point underperformance threshold required to trigger a negative director vote. No overboarding, attendance, independence, or qualification issues were identified for any nominee.

Total Comp

Prior Support
N/A
CEO total compensation of $14,867,600 is within a reasonable range for the chief executive of a $43.8 billion large-cap biotechnology company with multiple approved commercial products and strong revenue growth, and the pay mix is heavily weighted toward variable, performance-linked equity (stock options and performance stock awards together constitute a substantial majority of total pay), satisfying the policy's requirement that at least 50-60% of senior executive pay be at risk. The company's 3-year total shareholder return of +69.3% outperforms the XBI — SPDR S&P Biotech ETF (which returned +70.0% over the same period, a gap of only -0.7 percentage points) and substantially outperforms most compensation peers, indicating that above-benchmark incentive pay is supported by shareholder outcomes. The company maintains a meaningful clawback policy covering both cash and equity, and no prior-year say-on-pay vote below 70% was identified that would require a mandatory negative vote.
Auditor

Audit Fees
$4,455,027
Non-Audit Fees
$598,172
Non-audit fees (tax fees of $416,877 plus all other fees of $181,295, totaling $598,172) represent approximately 13.4% of audit fees ($4,455,027), well below the 50% threshold that would raise independence concerns; PwC is a Big 4 firm appropriate for a $43.8 billion market-cap company; no material restatements were disclosed; auditor tenure was not disclosed in the filing so the tenure trigger cannot fire and the default FOR vote applies.

The 2026 Alnylam annual meeting presents a clean ballot: all three Class I director nominees receive a FOR vote driven by strong 3-year total shareholder return that comfortably exceeds the peer-group and XBI benchmarks, the say-on-pay program earns a FOR vote reflecting a performance-linked pay structure aligned with substantial shareholder value creation, and PricewaterhouseCoopers' ratification is supported given a very low non-audit fee ratio of ~13% and no restatement or tenure concerns. No stockholder proposals were identified in the filing materials provided.
