One page per director: the seat, the committees and the fee table, read for one person at a time.

Every insider equity transaction reported on Form 4 after the 2025 proxy statement — acquisitions, dispositions, exercises, and withholdings — and therefore not reflected in any table in that document.

Transaction codes per Form 4: A acquisition · S open-market sale · F tax withholding · M option exercise · G gift. Value = shares × price as reported. Dividend-equivalent and fractional-share accrual rows (derivative Class A, under $10,000 and under 2,000 shares) are aggregated per date; every row appears in full below.

% performance-vested = PSU grant-date fair value ÷ (RSU + PSU + Options), a computed value with the derivation shown in the register.

Alnylam's executive compensation philosophy is designed to align executive interests with the drivers of growth and stockholder returns, incentivize the execution of company strategy, and attract and retain talented executives with market-competitive pay. The program ensures that the substantial majority of NEO compensation is performance-based and at-risk, driving the growth of sustainable long-term stockholder value.

Rows are labeled by annual-meeting year, with the meeting date beside each; the vote held in a given year acts on the prior fiscal year's compensation.

Say-on-pay — history, company's computation

a. Approved under the standard stated in the filing — “Abstentions and broker non-votes will have no effect on the outcome of Proposal 2.”.

b. Approved under the standard stated in the filing — “Abstentions and broker non-votes will not be counted as shares voting on this matter and accordingly will have no effect on the approval of this Proposal 3.”.

c. Approved under the standard stated in the filing — “Accordingly, abstentions and broker non-votes, if any, would have no effect on the vote for any of the Proposals to be considered at the annual meeting, because these Proposals are based on a percentage of the votes that are actually cast at the annual meeting.”.

Approval percentages are the company's own reported computations under its own stated standard, not recomputed by Velarion. Where a company does not state a standard, none is assumed.

Computed as the sum of the director compensation table rows above; inputs and formula shown in the register.

The compensation peer group as the company disclosed it in its own proxy — the reference set behind the percentile above.

Of the companies ALNYLAM PHARMACEUTICALS, INC. names as compensation peers, which name it back in their own disclosed peer groups. A peer set the market reciprocates reads differently from one selected in a single direction.

Reciprocity shown where the peer's own current proxy has been read — each mark is cited in the register to that peer's filing. A dash means the peer's current proxy was read and names no reciprocal group including ALNYLAM PHARMACEUTICALS, INC..

Most recent fiscal-year chief executive compensation at each disclosed peer, taken from that company's own proxy statement.

Each peer's compensation is from its most recently filed proxy; fiscal years differ by company. Each peer's figures come from its own filings; the subject company is highlighted. Peers whose chief executive compensation is outside our coverage universe are stated as such, never left blank.

Read from each company's Compensation Discussion and Analysis: annual incentive payout as a percentage of target, the disclosed long-term vehicle mix, whether performance-share measures include a total shareholder return component, and the retained compensation consultant. “Not disclosed” appears only where the company's filing does not state the item.

Answers are drawn only from the figures disclosed in this brief and cited to their location in the source filing. Where a figure required for an answer is not disclosed, that is stated rather than estimated.

Each figure's location is given both for the eye (section · page · table · row · column) and for a script (table/row/column index and exact character span in the filed document). Any figure can be independently confirmed against the source.
