1 serious warning sign in Kopin’s filings.

We look for five warning signs: doubt it can keep going, weak checks on its own accounts, a notice that its past accounts can't be relied on, a change of auditor, and one customer bringing in a big share of sales. We don't check lawsuits, investigations or debt yet.

We checked the auditor's report, internal controls, restatement notices, auditor changes and big customers in the 10-K filed 13 Apr 2026, plus the 10-Q filed 11 Aug 2026 and 6 later 8-Ks.

• Weak checks on its own accounts

  Serious

  The company said its checks on its own accounts did not work at the end of its latest quarter. Mistakes could slip into the numbers.

  “Based on that evaluation, our management concluded that, as of June 27, 2026, our disclosure controls and procedures were not effective as of June 27, 2026 due to the following material weaknesses which were disclosed in the Company’s Annual Report on Form 10-K for the year ended December 27, 2025, and continue to exist as of June 27, 2026:”

  As of June 27, 2026, the Company conducted an evaluation under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer (its principal executive officer and principal financial officer, respectively) regarding the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of June 27, 2026, as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The term “disclosure controls and procedures” means controls and other procedures that are designed to ensure that information required to be disclosed by the Company in reports that we file or submit under the Exchange Act are recorded, processed, summarized and reported within the requisite time periods and that such disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that we file or submit under the Exchange Act are accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation, our management concluded that, as of June 27, 2026, our disclosure controls and procedures were not effective as of June 27, 2026 due to the following material weaknesses which were disclosed in the Company’s Annual Report on Form 10-K for the year ended December 27, 2025, and continue to exist as of June 27, 2026:

• Changed auditor

  Worth knowing

  The company changed its auditor (the firm that checks its books) in the last two years.

  “On the same date the Board of Directors of the Company dismissed RSM US LLP (“RSM”) as the Company’s independent registered public accounting firm, effective immediately prior to the engagement of BDO.”

• One big customer

  Worth knowing

  One customer brings in a big share of sales: 63% last year. Losing that customer would hurt.

  “Key risks include dependence on major customers, such as DRS Network & Imaging Systems LLC comprising 63% of revenues in 2025 and therefore posing a concentration risk.”

• Sales have shrunk: 48.0% a year.

Whether the price already reflects the risks is what the deep dive is for.
