Except as set forth below, there are no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2023. See Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023, entitled “Risk Factors.”

RISKS RELATING TO THE SALE OF OUR CONSUMER PRODUCTS DIVISION (OUR TISSUE BUSINESS)

The completed divestiture may disrupt our remaining business or not achieve its intended benefits.

On July 21, 2024, we entered into a Membership Interest Purchase Agreement and an Asset Purchase Agreement with Sofidel America Corp. (“Sofidel”), a wholly owned subsidiary of Sofidel S.p.A., pursuant to which, among other things, we agreed to sell our consumer products division to Sofidel. The transaction closed on November 1, 2024. A number of risks and challenges may arise from the divestiture, including, among others:

•there may be unexpected costs, charges or expenses resulting from the divestiture; and

•there may be stockholder litigation in connection with the divestiture or other settlements or investigations may affect the timing or occurrence of the Tissue Divestiture or result in significant costs of defense, indemnification and liability.

In addition, the Tissue Divestiture could cause disruption in our remaining business, including potential adverse changes to relationships with customers, employees, suppliers or other parties resulting from the divestiture process. The Tissue Divestiture may also be disruptive to our regular operations, diverting the attention of our workforce and management team from the day-to-day operation of our business, making the execution of business and other potential strategies more difficult, and could result in increased undesired workforce turnover, including of key leaders or other personnel.

Even if we are successful at separating and divesting our Tissue Business, we may not realize some or all of the anticipated benefits from the Tissue Divestiture with respect to the anticipated performance of our remaining business. The Tissue Divestiture may result in continued financial exposure to the Tissue Business through the retention of certain liabilities, including, for example, with respect to certain environmental claims. The Tissue Divestiture may not enhance long-term stockholder value as anticipated and/or the efforts required to complete the divestiture process may be more costly or time-consuming than expected. Any of the foregoing could result in the imposition of obligations that could have a material adverse effect on our remaining business, operating results or financial condition.

On December 15, 2015, we announced that our Board of Directors had approved a stock repurchase program authorizing the repurchase of up to $100 million of our common stock. The repurchase program authorizes purchases of our common stock from time to time through open market purchases, negotiated transactions or other means, including accelerated stock repurchases and 10b5-1 trading plans in accordance with applicable securities laws and other restrictions. We have no obligation to repurchase stock under this program and may suspend or terminate the program at any time.

Shares of common stock withheld as payment of withholding taxes and exercise prices in connection with the vesting or exercise of equity awards are not required to be disclosed under Item 703 of Regulation S-K and accordingly are excluded from the amounts in the table above.
