CTO Mark Frichtl sells 18,414 OUST shares at $38.82 via pre-arranged 10b5-1 plan; stock now $42.73 (52-week range $16.40–$49.39)

Mark Frichtl, Chief Technology Officer, executed a scheduled sale of 18,414 shares under a pre-arranged 10b5-1 trading plan, reducing his holdings by -6.2% to 276,510 shares post-transaction. The sale occurred at $38.82 on 2026-06-12. Because this transaction is part of a pre-arranged plan rather than a discretionary trade, it reflects a predetermined schedule rather than a real-time market judgment. Orust remains unprofitable with a net income of $-17,465,000 in the latest quarter, though the company shows strong annual revenue growth of +52.5% and a market cap of $2,720,745,110.77. The insider's cross-ticker track record shows 20 prior open-market sells with an average 30-day return of +25.4%, though no measurable outcomes yet exist from his 5 prior trades at OUST (all from 2026-05-26).

CTO Mark Frichtl sold 384,426 shares ($15.6M) via scheduled 10b5-1 plan at blended $40.60; stock now $44.23

Mark Frichtl, Chief Technology Officer, executed 9 separate sales totaling 384,426 shares for $15,606,971.34 across May 22–26, 2026, reducing his non-derivative holdings from 679,350 shares to 294,924 shares (a 56.6% reduction). This filing is part of a pre-arranged 10b5-1 trading plan, meaning execution was scheduled rather than discretionary. The stock has risen 64.3% over the prior 30 days and 125.3% over 90 days, trading at $44.23 versus the blended sale price of $40.60. Frichtl's cross-ticker track record shows 19 prior sells averaged +45.2% 90-day return post-sale, though his prior 5 sales at OUST specifically ranged +18.6% to +29.4% forward performance; the current stock price sits near the 52-week high of $45.42. The company is generating $48.6M quarterly revenue with 52.5% annual growth but reported a $-17.5M net loss in its most recent full fiscal year, framing this sale within an unprofitable but rapidly growing business context.

OUST CTO Frichtl Mark sells 180,750 shares across 12 transactions for $6.0M via pre-arranged 10b5-1 plan, retaining 628,638 shares post-trade.

Frichtl Mark, Chief Technology Officer at Ouster, Inc. (OUST), executed 12 separate sales totaling 180,750 shares for $5,997,751.39 under a pre-arranged 10b5-1 trading plan, meaning the transactions were scheduled in advance and are not discretionary. The sales occurred across three days (2026-05-13 through 2026-05-15) at prices ranging from $2.13 to $36.00, and the stock has seen substantial recent appreciation — up +42.6% over 30 days and +85.7% over 90 days — providing favorable price context at the time of execution, though timing is not a property of a scheduled 10b5-1 plan. Frichtl retains 628,638 shares post-transaction, representing a meaningful ongoing economic interest in the company. Ouster remains unprofitable with net income of $-17,465,000.00 on quarterly revenue of $48,578,000.00, though annual revenue growth of +52.5% reflects strong top-line momentum.

Ouster CTO exercises stock options and immediately sells entire position, netting $1M gain over two days.

Mark Frichtl, Ouster's Chief Technology Officer, exercised stock options on two consecutive business days and sold the entire 34,600-share position immediately at prices ranging from $30.00 to $30.13 per share, realizing approximately $1M in gross proceeds. This is a textbook same-day or next-day exercise-and-sell pattern, which typically reflects option expiration deadlines or planned liquidity rather than conviction about the company. The stock currently trades well below its 52-week high despite having gained significantly over the past three months, creating favorable conditions for an executive to exercise and exit. Notably, Frichtl's five prior open-market sales at Ouster were all poorly timed—the stock rose after every exit, suggesting this insider has not successfully predicted downturns at this company. The company remains unprofitable despite strong revenue growth, which may explain why the CTO chose to liquidate his option gains rather than hold the underlying shares. This transaction leaves Frichtl's overall stake unchanged at approximately 712,697 shares, indicating the exercise-and-sell was purely a liquidity event, not a reposition.

Ouster CTO Mark Frichtl sold 120,000 shares over two days for $3,308,667.00 amid 37.7% rally; fifth consecutive sell at OUST in eight days.

Mark Frichtl, Chief Technology Officer, executed 4 separate sales totaling 120,000 shares for $3,308,667.00 across April 20–21, 2026, at an average price of $27.57. This represents a -14.4% reduction in his holdings to 712,297 shares. Notably, this filing is the fifth consecutive sell transaction at Oust in an 8-day window (April 14–20), signaling sustained liquidation activity from the CTO. The sales occur following a sharp +37.7% price run in the preceding 30 days, with the stock currently trading at $27.61, down -25.5% from its 52-week high of $37.08. Oust remains unprofitable (net income of $-21,733,000.00 in the latest quarter) despite strong revenue growth of +52.5% annually, raising questions about execution and path to profitability against an elevated valuation environment.

Ourst CTO Mark Frichtl sells 30,000 shares at $25.15; stock now $24.26, down 34.6% from 52-week high.

At current price of $24.26, the stock is -34.6% from its 52-week high of $37.08, though it has recovered +17.0% over the past 30 days. Frichtl's prior sells at Ouster (2026-04-15, 2026-04-14, 2026-03-25 outcomes not yet measurable, plus a 2025-09-12 sale) are clustered in recent weeks, suggesting repeated liquidation activity. The company is unprofitable (net income $-21.7M) despite 52.5% annual revenue growth, with market cap of $1.5B; this transaction occurs in an environment where the stock has recovered significantly from recent lows but remains well below its 52-week peak. The pattern of multiple sales in quick succession warrants attention to management confidence levels relative to near-term business trajectory.

CTO Mark Frichtl sells 60,000 OUST shares in 2 transactions for $1.4M at $22.76–$24.00 (blended $23.17); now holds 712.3K shares post-transaction.

The sales occurred at prices ($22.76 and $24.00, blended $23.17) near or slightly below the current price of $24.44, which sits 34.1% below the 52-week high but up 14.7% over the past 30 days. Frichtl's prior selling activity at OUST has been consistently well-timed: a September 2025 sale achieved a -7.3% 90-day return (the stock declined after the sale), and his cross-ticker record shows a 100% well-timed rate on his two prior sells with average 90-day return of -7.3%. The company is unprofitable with $-21.7M net income on $39.5M quarterly revenue, though it is growing revenue at +52.5% annually, creating mixed fundamental signals during a period of recovery in the stock price.

CTO Mark Frichtl sells 40,000 OUST shares at $20.94; stock down 52.4% from 52-week high, company unprofitable.

Mark Frichtl, Chief Technology Officer, sold 40,000 shares (40.0K shares) on 2026-03-25 at $20.94, reducing holdings by 5.9% to 636,882 shares (636.9K shares). The sale occurs against a backdrop of significant stock decline: OUST is trading at $17.66, down 52.4% from its 52-week high of $37.08 and down 10.8% in the past 30 days alone. The company remains unprofitable with a net income of $-21,733,000.00 (-$21.7M) in the most recent full fiscal year, though revenue growth of 52.5% annually shows business expansion. At the same ticker, Frichtl's prior sell in September 2025 was followed by a 7.3% decline at the 90-day mark, marking his only well-timed sale at OUST; however, his four prior buys at this ticker have delivered mixed results, with a 90-day win rate of 1 of 4 trades. The current sale in a deteriorating price environment warrants investor attention to whether the CTO's near-term view on execution or valuation has shifted.

CTO Mark Frichtl sold 25,329 shares of OUST at $28.46 on 2025-09-12 for $720,815.21; stock now at $29.75.

Mark Frichtl, Chief Technology Officer of Ouster, sold 25,329 shares at $28.46, reducing his holdings by -3.7% to 665,403 shares post-transaction.

The current sale comes against a mixed backdrop: the stock is -15.1% from its 52-week high of $35.05 and down -14.3% over 30 days, but has rebounded +46.3% over 90 days. Ouster remains unprofitable (latest quarter net income: $-20,612,000.00) despite accelerating revenue growth of +33.4% year-over-year, leaving fundamental support limited. The timing of this sale relative to his track record of poorly-timed purchases at this ticker warrants observation, though the modest -3.7% reduction in holdings preserves material exposure.
