How to read a U.S. public company’s Form 8-K material event report

If the company determines that previously issued financial statements are no longer reliable due to errors disclosed in the report, such disclosure is required under this item. Disclosure is also required if the auditor determines that its previously issued audit report or interim review of the financial statements is no longer reliable. In both cases, the company must also disclose whether its audit committee, board of directors as a whole, or authorized executive officers have discussed these matters with the auditor. Investors should pay attention to these disclosures, as they may affect the company’s previously reported earnings. Following the filing of an 8-K, companies typically restate their financial statements—though such restatements generally occur later. Item 5.01 — Change in Control If there is a change in control of the company, the company must identify the new controlling person and the percentage of voting securities held beneficially by that person, as well as any agreements between the former and new controlling persons regarding the election of directors or other matters. Item 5.02 — Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers If a director resigns, declines to stand for re-election, or is removed from office due to disagreements with the company concerning operations, policies, or practices, the company must briefly describe the nature of those disagreements. If the director provides a letter regarding the resignation, refusal to stand for re-election, or removal, the company must file that letter as an exhibit to the 8-K. If a senior officer (e.g., CEO, president, CFO, chief accounting officer, or COO) retires, resigns, or is terminated, the company must disclose that fact. The company must also disclose the appointment of any new director or senior officer and briefly describe any related compensation arrangements. Additionally, it must disclose any changes in the compensation of current senior officers. Item 5.03 — Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year If the company amends its articles of incorporation or bylaws, or changes its fiscal year, disclosure under this item is generally required—unless the proposed amendment or fiscal-year change has already been disclosed in a proxy statement or information statement. Companies issuing only debt securities are generally exempt from this requirement. Item 5.05 — Amendments to Registrant’s Code of Ethics, or Waiver of a Provision of the Code of Ethics Companies are generally required to report amendments to their code of ethics applicable to the principal executive officer, principal financial officer, principal accounting officer, or other senior officers. Companies must also disclose any waivers granted to such individuals. Many investors view ethical waivers as red flags. Note that companies may elect to post these disclosures on their corporate websites instead of filing an 8-K. Item 5.07 — Submission of Matters to a Vote of Security Holders Within four business days after the conclusion of an annual or special meeting, the company must report the results of shareholder votes on director elections and all other matters requiring a vote. If only preliminary results are available at that time, the company must file an amended 8-K within four business days after final results are announced. Item 7.01 — Regulation FD Disclosure Regulation FD (“Fair Disclosure”) aims to prevent selective disclosure of material nonpublic information. Its purpose is to level the playing field: companies must generally make material information publicly available at the same time they provide it to others—such as securities market professionals. A company may use an 8-K filed under this item or Item 8.01 to satisfy Regulation FD’s public disclosure requirements.
