Yaffe Kristine 4

What Happened
Kristine Yaffe, a director of Alector, Inc. (ALEC), was granted equity awards on June 17, 2026: 28,700 restricted stock units (RSUs) and 9,450 derivative units (reported as a derivative award). Both grants were reported at $0 per share (no cash paid). These are award-type grants rather than open-market purchases or sales, so they represent compensation/equity incentives rather than a bullish or bearish trading signal.

Key Details

• Vesting (Footnotes):
  • F1: RSUs vest the earlier of June 17, 2027 or the issuer’s next annual meeting of stockholders.
  • F2: The derivative/option-related shares vest in 12 equal monthly installments beginning July 17, 2026, but accelerate to full vesting on the earlier of the one-year anniversary of the grant or the next annual meeting.

• Timeliness: Filing date matches transaction date — appears to be filed on time.

Context
These are standard director compensation awards (RSUs and derivative/option-linked units). Because the grants were issued at $0, no cash changed hands. Such awards are common for board members to align incentives; they are not the same as open-market purchases or sales and do not by themselves indicate the director’s intent to buy or sell shares in the market.
