Significance 5

CFO Andrea J. Funk bought 108 ENS shares at $228.47; prior same-ticker buy showed +22.3% 90-day return.

CFO Andrea J. Funk purchased 108 shares of EnerSys at $228.47, increasing her holdings to 56,396 shares (+0.2% net change). Her prior buy at this ticker on 2025-05-23 delivered a +22.3% 90-day return, and her cross-ticker track record shows a 100.00% win rate with +22.3% average 90-day return across 1 prior buy. The stock has appreciated 39.2% over the past 90 days and 7.3% in the past 30 days, though it currently trades at $227.89 (-6.7% from its 52-week high of $244.30). The company reports $919.1M quarterly revenue, $90.4M net income, and a P/E of 34.32, indicating substantial but not stretched valuation relative to growth. The purchase comes within a pattern of successful prior timing at this ticker.

President Motive Power Global sells 6,702 shares for $1,015,084.92 on 2025-12-10, reducing holdings by 22.0%

Chad C Uplinger, President of Motive Power Global at EnerSys, executed two separate sales on 2025-12-10 totaling 6,702 shares (22.0% of prior holdings) at $151.46 per share, reducing his position from 30,415 shares to 23,713 shares. The transaction occurred near the 52-week high of $151.16, with the stock currently trading at $147.26. While his single prior open-market buy at ENS in May 2025 was followed by a 90-day gain of +22.2%, the current sale is positioned at an elevated valuation level relative to historical range. The scale of the reduction (over one-fifth of holdings) and proximity to the 52-week high merit monitoring for any accompanying commentary on business outlook or capital allocation plans.

CEO O'Connell buys 475 ENS shares at $83.76; cluster pattern with 2 other insiders in 14 days

O'Connell Shawn M., President & CEO, purchased 475 shares at $83.76 on 2025-05-30, bringing his holdings to 43,030 shares. This transaction occurs within a 14-day cluster in which 2 other insiders also bought, establishing a multi-party accumulation pattern. The purchase occurred at a price $1.68 above the current market price of $82.08, and the stock is down 25.5% from its 52-week high of $110.19 and down 9.6% over the prior 30 days. With a P/E of 7.61 and recent quarterly net income of $114.8M against revenue of $906.2M, the company trades at a low multiple, yet concurrent insider buying by multiple executives suggests internal confidence during a period of near-term weakness.

President of Motive Power Global buys 295 ENS shares at $83.65; stock down 25.5% from 52-week high amid cluster pattern

Chad C Uplinger, President of Motive Power Global, purchased 295 shares of EnerSys at $83.65 on 2025-05-30, bringing holdings to 17,545 shares post-transaction. The purchase occurred as ENS trades at $82.08, down -25.5% from its 52-week high of $110.19 and down -16.6% over the past 90 days, suggesting acquisition during a period of price weakness. Two other insiders also bought within the past 14 days, forming a cluster buy pattern that may reflect operational confidence amid revenue of $906.2M and net income of $114.8M in the latest quarter. This transaction alone is modest in size and value, and without additional context about the filer's investment rationale or prior trading history at this ticker, the cluster pattern provides the only observable signal worth noting.

Significance 4

CFO Funk buys 315 ENS shares at $80.20; stock down 18.6% in 90 days, trading -24.5% from 52-week high at $110.19.

Andrea J. Funk, EVP & Chief Financial Officer, purchased 315 shares of EnerSys at $80.20 on 2025-05-23, increasing her holdings from 50,330 shares to 50,645 shares. The transaction occurs within a notably weak price context: the stock is trading at $83.23, down 18.6% over the past 90 days and 24.5% below its 52-week high of $110.19. The company maintains solid fundamentals with $906.2M in quarterly revenue, $114.8M net income, and a P/E of 7.71, suggesting the stock trades at a relatively low multiple despite recent price weakness. This insider purchase by a senior finance executive during a period of significant stock decline provides a data point on capital allocation decisions at the executive level, though the modest size relative to her existing 50.6K-share position limits broader inference.

Significance 8

EnerSys CEO Shaffer David M sold entire remaining 11,378 shares (100% of holdings) for $1,150,604.41 on 2025-02-25

On February 25, 2025, Shaffer David M (CEO of EnerSys) executed 6 separate sales totaling 11,378 shares for $1,150,604.41 at prices ranging from $100.42 to $102.03 (blended average $101.13), completely liquidating his equity position to zero shares. This represents the elimination of 100% of his prior shareholdings, which is a material departure from typical CEO holdings and represents a definitive exit of direct equity stake in the company. The sale occurred at prices near the current market price of $102.19 and during a period when the stock is trading -7.3% from its 52-week high of $110.19, though up 6.3% over the past 30 days. The CEO's complete equity exit merits investor scrutiny given the fundamental context: EnerSys generated $906.2M in quarterly revenue and $114.8M in net income, but is facing -3.4% annual revenue growth with a valuation of 12.28x P/E at a $4.0B market cap.

Significance 7

CEO Shaffer sold 74,156 shares for $7,540,707.76 over two days, reducing stake 92.9%.

Shaffer David M, the CEO of EnerSys, executed 12 separate sales totaling 74,156 shares for $7,540,707.76 on February 21 and 24, 2025, at prices ranging from $100.74 to $103.56 per share (blended average $101.69). This represents a 92.9% reduction in his holdings, from 79,845 shares pre-transaction to 5,689 shares post-transaction. The magnitude and rapidity of this near-complete liquidation by the company's top executive warrants investor attention, particularly given that EnerSys reported annual revenue growth of -3.4% and carries a relatively modest P/E of 12.25 in a $4.0B market-cap business. The sales occurred near the 52-week high ($110.19), though currently 7.5% below that peak. Investors should monitor whether this level of insider divestment reflects broader capital allocation choices or shifts in management's stance toward the company.

Significance 7

CEO Shaffer sells 44,300 shares (50.9% of holdings) in 14 transactions for $4.5M at $101.63 avg.

CEO David M Shaffer conducted 14 separate sales on February 19–20, 2025, reducing his stake in EnerSys from 87,067 shares to 42,767 shares—a 50.9% reduction. The transactions totaled 44,300 shares for $4,502,128.68, executed across a narrow price band ($100.62–$103.01), suggesting orderly liquidation rather than panic selling. Notably, this large single-event reduction is material relative to his pre-transaction holdings, though the stock's current price of $102.10 sits only 7.3% below the 52-week high and has gained 2.2% over the past 30 days and 4.7% over 90 days, indicating the stock was not under distress at execution. The company's fundamentals show a P/E of 12.27 with revenue of $906,152,000.00 and net income of $114,812,000.00, though annual revenue growth stands at -3.4%, suggesting modest headwinds. Without FLAGS indicating a 10b5-1 plan or other scheduled mechanism, the scale of the liquidation—trimming his position by half in a two-day window—warrants attention to whether this reflects a shift in the insider's capital allocation strategy or confidence posture at the current valuation.

Significance 5

CEO David M Shaffer sold 15,662 shares of ENS at $100.18 on 2025-02-12 for $1,568,981.57

CEO David M Shaffer sold 15,662 shares at $100.18, reducing holdings by 16.9% to 77,086 shares. The stock has since declined to $99.33 and remains 9.9% below its 52-week high of $110.19, suggesting the transaction occurred near an intermediate peak. Across his cross-ticker open-market history, Shaffer has executed 2 prior sells with a 100.00% well-timed rate at the 90-day mark (average 90d return -3.8%), though at ENS specifically, only 1 of 1 measurable prior sales was well-timed (2024-08-29 sell showed 90d return of -3.8%). The company's revenue declined 3.4% year-over-year despite $906.2M in latest quarterly revenue and a modest P/E of 11.94, leaving baseline operational context mixed. This sale merits standard monitoring as a material equity transaction by the chief executive.

Significance 6

CEO David M Shaffer sold 20,000 shares of ENS at $100.01 on 2024-11-25 for $2.0M; retains 129.8K shares

CEO David M Shaffer sold 20,000 shares at $100.01, reducing his holdings by -13.3% from 149.8K shares. His cross-ticker track record shows 1 prior sell with a 90d well-timed rate of 100.00%, indicating that prior sale occurred before a subsequent decline. At EnerSys specifically, his prior sell on 2024-08-29 delivered -3.8% over 90 days, consistent with his overall pattern. The current price of $96.26 is -12.6% below the 52-week high of $110.19, and the stock has declined -4.5% in the past 30 days. Fundamentals show the company with $883.7M quarterly revenue and net income of $82.3M, though annual revenue growth stands at -3.4%. The timing of this sale within a declining price environment aligns with the historical pattern observed in his prior transactions.
