Understanding your High Grade Materials Co data breach notification letter

If a High Grade Materials Co letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.

Why you received this letter

High Grade Materials Co appears to be an industrial manufacturing or construction supply company that manages complex supply chains and large-scale procurement operations. In the course of their business, they typically collect and store sensitive information including employee payroll records, vendor tax documentation, and customer credit applications. This data breach was officially reported to the Indiana Attorney General in 2025, confirming that unauthorized parties may have accessed company systems. If you have received a data breach notification letter from the company, it indicates that your personal information was likely contained within the compromised files. We are currently analyzing the scope of this incident to determine how it impacts the privacy and security of those affected by this exposure.

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate High Grade Materials Co notice references the specific incident reported to the Indiana Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.

  2. Keep the letter — it is your proof of connection

    The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.

  3. Protect your accounts and credit
