Significance 5/10

Director Amron bought 4,500 shares at $3.25 avg at TUSK; stock down 5.0% in 30d but up 45.7% in 90d; weak cross-ticker timing history (37.5% win rate)

Arthur H Amron purchased 2 separate quantities (2,500 shares at $3.22 on 2026-06-11 and 2,000 shares at $3.28 on 2026-06-12) totaling 4,500 shares for $14,609.75 at a blended average of $3.25. The current price of $3.03 sits 22.7% below the 52-week high and has declined 5.0% over the past 30 days, though it is up 45.7% over 90 days. At TUSK specifically, Amron's prior measurable trades show mixed results: a December 2025 buy returned +11.6% in 30 days and +16.4% in 90 days, while a May 2024 buy returned -10.1% in 30 days and +3.6% in 90 days. Across his broader cross-ticker trading history, Amron's 10 prior open-market buys have averaged -4.3% return after 30 days and -6.4% after 90 days, with a 37.50% win rate at the 90-day mark. The company faces significant revenue headwinds (annual revenue contracted 76.4% year-over-year), which investors should weigh against the director's recent accumulation and his mixed historical timing record.

Significance 5/10

Director Arthur H Amron bought 5,500 shares over 2 days at avg $3.25, raising stake to 62.6K shares (+9.6%)

Arthur H Amron executed two separate purchases totaling 5,500 shares for $17,849.75 at an average price of $3.25 on May 26–28, 2026, increasing his holdings from 57.1K shares to 62.6K shares. The current price of $3.21 sits -10.8% below the 52-week high of $3.60, though recent momentum is positive: the stock is up 13.8% over 30 days and 39.0% over 90 days. Amron's same-ticker history shows mixed results—3 of his 5 prior buys at TUSK were well-timed at the 90-day mark, but his cross-ticker track record across all stocks averages a 90-day return of -6.4% with only a 37.50% win rate. The company's fundamentals are stressed: annual revenue growth contracted -76.4% year-over-year, though the latest quarter still posted $22.0M in revenue and $5.2M in net income, supporting a P/E of 15.29 and market cap of $154.6M. This purchase occurs in an environment of recent stock strength but deteriorating top-line performance, warranting examination of whether the insider's timing reflects genuine operational recovery or the recent price appreciation itself.

10,000 shares
$18,900
Significance 3/10

Director Amron Arthur H bought 10,000 TUSK shares at $1.89; stock now $1.73, down 49.4% from 52-week high amid -39.3% annual revenue decline.

Amron Arthur H purchased 10,000 shares at $1.89 on 2025-12-11, increasing his holdings by 21.2% to 57,135 shares post-transaction. The stock has since declined to $1.73, trading 49.4% below its 52-week high of $3.42, with negative 30-day and 90-day returns of -11.3% and -26.7% respectively. His cross-ticker track record shows 7 prior buys with an average 90-day return of -9.7% and a 28.57% win rate, while his prior 4 trades at TUSK specifically show mixed timing: 2 of 4 prior buys were well-timed at the 90-day mark. Against this backdrop, MAMMOTH ENERGY SERVICES is materially deteriorating financially—annual revenue declined 39.3% year-over-year, the most recent quarter generated only $14.8M in revenue, and the company posted a $-12.6M net loss, reflecting sustained unprofitability. The combination of weak historical trade timing, significant stock decline post-purchase, and deteriorating fundamentals suggests this is not a high-conviction signal.

Buy
1,000 shares
$2,971
Significance 4/10

Director Amron Arthur H bought 1,000 shares of TUSK at $2.97 on 2024-12-12; stock down 8.2% in 30 days, 21.7% in 90 days.

Director Amron Arthur H purchased 1,000 shares at $2.97, increasing holdings to 47.1K shares. The company is unprofitable with net income of $-24.0M against quarterly revenue of $40.0M, and revenue declined 14.5% year-over-year. The stock has fallen 8.2% over 30 days and 21.7% over 90 days, trading at $2.92 (38.7% below the 52-week high of $4.76). His prior three purchases at TUSK show a mixed timing record at the 90-day mark—two proved well-timed with positive returns (+3.6% and +5.8%) but one was poorly timed (-3.5%)—making it unclear whether this purchase represents a contrarian entry point or continued exposure to a deteriorating position. The recent 30- and 90-day declines suggest structural headwinds rather than a near-term recovery setup.
