MAKOWSKI TIM A 4

What Happened
Tim A. Makowski, Vice President, Controller and Chief Accounting Officer of Advanced Drainage Systems, received equity awards on May 26, 2026. The filing shows (a) 847 shares awarded at $0.00 (current allocation under the KSOP) and (b) 1,886 derivative shares/options granted at $0.00 (total 2,733). The awards were reported on Form 4 filed May 28, 2026. These are grants/awards (not open-market purchases or sales), so they reflect compensation rather than an investment purchase.

Key Details

• Transaction date(s): 2026-05-26; Form 4 filed: 2026-05-28 (appears timely).
• Awards: 847 shares (cash value reported $0.00); 1,886 derivative award units/options (reported $0.00). Total awards = 2,733 units/shares.
• Footnotes: F1 = represents current allocation under KSOP; F2 = options vest in three equal annual installments beginning May 26, 2027, subject to continued employment.
• Shares owned after transaction: not specified in the provided filing excerpt.
• Transaction type: A (award/grant) — neither a purchase nor a sale.

Context

• The 847-share item appears to be an allocation under the company’s KSOP (per footnote) and the 1,886-item is a derivative award with a multi-year vesting schedule — meaning value is tied to continued employment and future vesting, not an immediate sale.
• Awards at $0.00 are standard for compensation grants (they do not represent an open-market purchase at zero price). These filings report grants and vesting terms rather than signaling an immediate trading decision.
