Frequently Asked Questions About the NPKI Investigation

Q: Which statements are being investigated as potentially misleading? A: The investigation concerns whether NPK International made materially false or misleading statements regarding its business outlook and 2026 financial expectations. The stock price declined after the Company disclosed its third-quarter 2026 results and a reduced full-year 2026 revenue range on October 29, 2026.

Q: When did NPK International allegedly mislead investors? A: The investigation concerns statements made before the Company's October 29, 2026 disclosure. These statements allegedly caused investors to purchase securities at inflated prices.

Q: Who is eligible to participate in the NPKI investigation? A: Investors who purchased NPKI stock or securities and suffered financial losses may be eligible. Eligibility is based on purchase date and documented losses -- not on whether you still hold the shares.

Q: What do NPKI investors need to do right now? A: Investors may gather brokerage records showing purchase dates, share quantities, and prices paid. Submit your information for a no-cost, no-obligation evaluation of your potential recovery. No immediate Action is required to remain eligible to participate in the investigation.

Q: What documents do I need to participate? A: You will need brokerage statements or trade confirmations showing purchase dates, share quantities, prices paid, and any subsequent sale dates and prices.

Q: What if my NPKI losses are small -- is it still worth contacting a lawyer? A: Yes. There is no minimum loss amount required to participate in the investigation.

Q: What does it cost me to participate? A: There is no upfront cost to submit your information and review whether you may be eligible to recover. Should you choose to participate in any resulting Action , these matters are generally handled on a contingency basis. Any attorneys' fees and expenses are subject to court approval.

Q: Do I need to go to court or give testimony? A: No. Participating in the investigation does not require court appearances or depositions. If legal Action is later pursued, the overwhelming majority of affected investors never appear in court either.
