ENERGIZER HOLDINGS, INC. ANNOUNCES PRICING OF COMMON STOCK AND

MANDATORY CONVERTIBLE PREFERRED STOCK

St. Louis, Missouri, January 15, 2019 — Energizer Holdings, Inc. (NYSE: ENR) (the “Company”), today announced that the Company has priced concurrent offerings of 4,076,086 shares of common stock at a price to the public of $46.00 per share (the “Common Stock Offering”) and 1,875,000 shares of 7.50% Series A Mandatory Convertible Preferred Stock at a price to the public of $100.00 per share (the “Mandatory Preferred Offering,” and together with the Common Stock Offering, the “Offerings”). The Company is conducting the Offerings pursuant to an effective registration statement under the Securities Act of 1933. The underwriters have a 30-day option to purchase up to an additional 611,412 shares of its common stock and up to an additional 281,250 shares of its mandatory convertible preferred stock. The Offerings are scheduled to be completed on January 18, 2019, subject to customary closing conditions.

The net proceeds from the Common Stock Offering and the Preferred Stock Offering will approximately be $178.7 million and $181.3 million, respectively (or approximately $205.6 million and $208.6 million, respectively, if the underwriters exercise their option in full), in each case after deducting issuance costs and discounts.

The Company intends to use a portion of the net proceeds from the Offerings to pay the cost of the capped call transactions described below. The Company intends to use the remainder of the net proceeds from the Offerings to fund the acquisition of the global auto care business of Spectrum Brands Holdings, Inc. (“Spectrum”) pursuant to the terms and conditions of the Acquisition Agreement, dated as of November 15, 2018, by and between the Company and Spectrum (the “Auto Care Acquisition”) and pay related fees and expenses. The Offerings are not contingent upon each other, nor are they contingent upon the closing of the Auto Care Acquisition. If for any reason the proposed Auto Care Acquisition has not closed or if certain acquisition termination events occur, the Company expects to use the net proceeds from the Offerings for general corporate purposes, which may include, in the Company’s sole discretion, exercising the option to redeem mandatory convertible preferred stock for cash, debt repayment, capital expenditures, investments and repurchases of the Company’s common stock at the discretion of its board of directors.

J.P. Morgan, Barclays and Citigroup are acting as lead book-runners, and BofA Merrill Lynch, Evercore ISI and MUFG are acting as joint book-running managers for the Offerings.

Unless earlier converted, each share of mandatory convertible preferred stock will automatically convert on January 15, 2022 (subject to postponement for certain market disruption events) into between 1.7892 and 2.1739 shares of the Company’s common stock, subject to certain customary anti-dilution adjustments.

Dividends on the mandatory convertible preferred stock will be payable on a cumulative basis when, as and if declared by the Company’s board of directors, at an annual rate of 7.50% on the liquidation preference of $100.00 per share. If declared, these dividends will be paid in cash, in shares of the Company’s common stock or, in a combination of cash and shares of the Company’s common stock, at the Company’s election, on January 15, April 15, July 15 and October 15 of each year, commencing on April 15, 2019, and continuing to, and including, January 15, 2022.

In connection with the Mandatory Preferred Offering, the Company entered into capped call transactions with one or more financial institutions, including certain of the underwriters or their affiliates (the “Option Counterparties”). The capped call transactions are expected generally to reduce or offset the potential dilution upon conversion of the mandatory convertible preferred stock, with such reduction subject to a cap. The cap price of the capped call transactions will initially be $64.40 per share of the Company’s common stock, representing a premium of 40% above the public offering price of the Company’s common stock in the Common Stock Offering, and is subject to certain adjustments under the terms of the capped call transactions. If the underwriters exercise their option to purchase additional shares of mandatory convertible preferred stock, the Company expects to enter into additional capped call transactions with the Option Counterparties.

The Company expects that, in connection with establishing their initial hedge of the capped call transactions, the Option Counterparties or their affiliates may enter into various derivative transactions with respect to the Company’s common stock concurrently with or shortly after the pricing of the Mandatory Preferred Offering. These activities could increase (or reduce the size of any decrease in) the market price of the Company’s common stock at that time.

In addition, the Company expects that the Option Counterparties or their affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to the Company’s common stock and/or by purchasing or selling the Company’s common stock or other securities of the Company in secondary market transactions following the pricing of the Mandatory Preferred Offering and prior to the mandatory conversion date of the mandatory convertible preferred stock (and are likely to do so during the final averaging period relating to the mandatory conversion of the mandatory convertible preferred stock). This activity could also cause or avoid an increase or a decrease in the market price of the Company’s common stock, which could affect the value of the shares of the Company’s common stock that will be received upon conversion of the mandatory convertible preferred stock and, to the extent the activity occurs during the final averaging period relating to the mandatory conversion of the mandatory convertible preferred stock, it could also affect the number of shares of the Company’s common stock that will be received upon conversion.
