American Tower (AMT) Director Grace Lieblein Receives RSU Award

What Happened
Grace Lieblein, a director of American Tower Corporation (AMT), was granted 1,209 restricted stock units (RSUs) on March 10, 2026. The grant is reported at an acquisition price of $0.00 (transaction code A — award/grant). Each RSU is a contingent right to receive one share of AMT common stock upon vesting; the filing does not report an immediate cash value because payout depends on AMT’s share price at vesting.

Key Details

  • Transaction date: March 10, 2026; Form 4 filed March 12, 2026. This appears to be within the typical two-business-day reporting window for insiders.
  • Security/amount: 1,209 RSUs granted, reported at $0.00 acquisition price.
  • Vesting: According to the footnote, RSUs vest on March 10, 2027. Each RSU converts to one share upon vesting.
  • Shares owned after transaction: Not specified in the filing summary provided.
  • Footnote: RSUs granted under the 2007 Equity Incentive Plan (as amended); each RSU represents a contingent right to one share.
  • Transaction code: A = Award/Grant (compensation-related).

Context
This is a standard equity compensation award to a board member, not a purchase or sale. RSU grants are routine director compensation and do not by themselves signal a buy or sell decision — value is realized only if and when the RSUs vest (and potentially upon subsequent sale).
