Significance 6/10

Executive Chairman Platzer sold 204,248 shares ($1.9M) across 10 transactions; stock up 95.5% in 30 days and 105.7% in 90 days post-initial filing.

Platzer executed 10 separate sales totaling 204,248 shares for $1,884,577.44 across 13 months (May 2024–January 2026) at a blended average price of $9.23, reducing his holdings by 12.1%. The filing occurs during a dramatic recovery: the stock has surged 95.5% over the prior 30 days and 105.7% over the prior 90 days, now at $21.56—well above the $7.59–$12.45 prices at which Platzer executed most of his sales. At the same ticker, his prior 4 sells showed a 25% well-timed rate (1 of 4 resulted in declines within 90 days), while his cross-ticker track record shows a 25% well-timed rate with an average 90-day return of +1.6% after his sales—indicating his historical sells did not systematically precede declines. Fundamentally, the company is unprofitable ($-19.7M net income last quarter) with contracting revenue (-35.2% annual growth), yet the stock has recovered substantially, creating a temporal mismatch between when he sold (at prices reflecting distress) and when the stock rebounded.

Sell
130,191 shares

Significance 6/10

Platzer (CEO) sold 130,191 shares at $12.25; stock now $12.16, down 41.5% from 52-week high; SPIR unprofitable with $-20.7M net loss last period.

Platzer sold 130,191 shares (7.5% of pre-transaction holdings) at $12.25 on 2025-07-08, consistent with a pattern of recurring sales at SPIR—he has executed 5 prior trades at this ticker in the past 8 months. The current price of $12.16 sits well below the 52-week high of $20.78 (down 41.5%), and at the same-ticker level, his prior three measured sales showed decidedly negative 30-day outcomes (-13.1%, -24.0%, -29.6%), though longer-term 90-day outcomes have been mixed (+10.5%, +2.4%, -14.8%). SPIR remains fundamentally unprofitable with a net loss of $-20.7M in the latest period despite 13.2% annual revenue growth, creating structural pressure on the stock and a backdrop where recurring insider selling may reflect limited near-term upside visibility.

Significance 7/10

Executive Chairman Platzer sold 145,600 shares for $1,511,716.16 on 2025-03-04; stock down 45.5% in 30d, 29.9% in 90d

Peter Platzer, Executive Chairman of Spire Global (SPIR), executed 2 separate sales totaling 145,600 shares for $1,511,716.16 on 2025-03-04 at blended average price $10.38, reducing his holdings by 7.9% to 1,694,757 shares post-transaction. The stock is now trading at $10.35, down 45.5% over 30 days and 29.9% over 90 days from the transaction date, placing it 50.2% below its 52-week high of $20.78. Across his cross-ticker track record, Platzer's 2 prior open-market sells achieved a 90-day well-timed rate of 100.00%, and at SPIR specifically, both of his 2 prior sales (Nov 2024 and May 2024) were followed by 90-day declines of -14.8% and -19.1% respectively. The company remains unprofitable (net income of -$12,473,000.00 in the latest quarter) despite 31.7% annual revenue growth, and the ongoing sharp stock decline continues the established pattern of Platzer's sales preceding downward pressure.

Sell
50,238 shares
$741,865
Significance 6/10

CEO Platzer sells 50,238 shares of SPIR at $14.77; stock up 77.6% in 30d, but company unprofitable with $-25.3M net income last quarter.

Platzer, the CEO, sold 50,238 shares at $14.77 on 2024-11-21, reducing holdings by 2.6% to 1,891,703 shares. The sale occurred as SPIR stock gained 77.6% over the prior 30 days and 98.0% over 90 days, pricing near its 52-week high of $17.47 at the time of the sale. However, the underlying business remains unprofitable: the company reported a net loss of $-25.3M against revenue of $25.7M in its latest quarter, though it achieved annual revenue growth of 31.7%. The CEO's discretionary sale during a strong rally, despite the company's lack of profitability, presents a mixed signal that warrants scrutiny against the broader fundamentals.
