Howard Justyn Russell

Justyn Russell Howard's Form 4 record at Sprout Social is a single-issuer history — 384 transactions since February 2020, all tied to SPT, with 2,512,394 shares sold and zero bought on the open market. The recent filings follow a fixed, recurring structure: a block of shares is converted from a derivative security under code C, then sold the same day under code S, then a matching code-C entry closes the filing — a pattern that repeats on a roughly monthly cadence regardless of price. What changes across those repetitions is the price itself: $16.378 on 2025-08-05, $14.937 on 2025-09-05, $11.81 on 2025-10-07, $10.218 on 2025-11-04, $11.115 on 2025-12-11, $5.033 on 2026-04-10, and $8.284 on 2026-07-10 — an eight-month span in which the same 20,000-to-40,000-share block size sold at less than a third of its August price by April, before partially recovering by July.

The block size itself doubled partway through: 20,000 shares per conversion-and-sale cycle from August through November 2025, stepping up to 40,000 shares from December 2025 onward, a size that held steady even as the per-share price fell from $11.115 to $5.033 between those two ends. A handful of smaller, irregular sales — 10,566 shares on 2025-09-03, 10,291 on 2025-12-04, and 23,855 on 2026-03-03 — sit outside the main monthly cycle.
