Significance 7/10

Director Donal L Mulligan bought 15,000 ENR shares at $17.40; holdings now 25,000 shares. Stock -52.9% from 52-week high; cluster of 3 insider buys in 14 days.

Mulligan purchased 15,000 shares at $17.40, tripling his prior 10,000-share stake to 25,000 shares post-transaction. The purchase price of $17.40 sits near the 52-week low of $17.02, and the stock is currently trading 35.2% below its 90-day starting point and 52.9% below its 52-week high of $39.39. His prior ENR purchase on 2025-05-19 posted a +17.9% 90-day return, and across his cross-ticker buying history, his 90-day win rate is 100.00% with an average 90-day return of +17.1%. A cluster pattern is present: 2 other insiders also bought ENR within the past 14 days. The company's fundamentals show a P/E of 2.81 on revenue of $725.3M and net income of $153.5M, suggesting a discounted valuation at current levels. This convergence of a director's material purchase at historically low levels, combined with coordinated buying activity by other insiders, warrants investor attention as a potential reversal signal after sustained price deterioration.

Significance 6/10

Director Mulligan bought 10,000 ENR shares at $23.66; stock down 39.6% from $39.39 high, cluster of 5 insiders bought in past 14 days

Director Donal L Mulligan purchased 10,000 shares of Energizer at $23.66, establishing a new position with a total value of $236,600.00. The purchase occurs amid significant recent weakness: the stock is trading 39.6% below its 52-week high of $39.39 and down 24.1% over the 90-day period. Notably, this is part of a cluster pattern—5 other insiders also made purchases within the past 14 days—suggesting multiple company insiders are transacting at lower price levels. Mulligan's cross-ticker track record shows positive outcomes (avg 90d return +16.4%, 100% win rate) across his prior open-market activity, though this represents his initial position in Energizer and does not establish his accuracy specific to this ticker.
