Interim CFOs: what an interim appointment means in a filing

How an interim or acting CFO appears in a Form 8-K, what the filing must disclose about that officer, and how often interim appointments show up on the record.

By Editorial Desk · Published October 23, 2026 · 5 min read

An interim CFO is an officer a company names to perform the principal financial officer's job while it decides who will hold the seat. In SEC filings, the word "interim" is the company's own label. The rules do not define an interim officer and do not treat one differently from a permanent appointee. What changes in a filing is the wording, not the obligation.

On CFO Tribune, 94 of the 418 verified moves are interim appointments, or 22%. In the year before this page was built, the share was 22%. This guide explains what those records rest on.

The rule makes no distinction

Item 5.02(c) of Form 8-K applies when a company "appoints a new principal executive officer, president, principal financial officer, principal accounting officer, principal operating officer, or person performing similar functions." The phrase "person performing similar functions" matters here. An officer named "interim chief financial officer" or "acting principal financial officer" performs the functions of the principal financial officer, so the appointment falls inside Item 5.02(c) like any other.

That means an interim appointment filing is supposed to carry the same disclosures as a permanent one:

  • "the name and position of the newly appointed officer and the date of the appointment";
  • the information required by Items 401(b), (d) and (e) of Regulation S-K: age and positions held, any family relationship with a director or executive officer, and "the business experience during the past five years";
  • the related-person transactions Item 404(a) calls for;
  • "a brief description of any material plan, contract or arrangement" entered into or materially amended in connection with the appointment.

The deadline is the same too. General Instruction B.1 gives "four business days after occurrence of the event," and the Instruction to paragraph (c) lets the company file on the day it otherwise announces the appointment.

What an interim filing usually looks like

Interim appointments tend to arrive in one of three shapes:

  • Inside a departure filing. The same 8-K reports under Item 5.02(b) that the CFO "retires, resigns or is terminated from that position," and under Item 5.02(c) that another officer will serve in the interim. CFO Tribune records this as an interim move with both names.
  • On their own. A company that reported a departure earlier files again when it names someone to act in the role.
  • As a designation. A company says an existing officer, often the chief accounting officer, controller or chief executive officer, will "serve as" or "assume the duties of" principal financial officer. The filing may never use the word interim.

The last shape is why CFO Tribune reads the designation, not the job title. If the filing makes someone the principal financial officer "on an interim basis," the move is interim. If it says the person is appointed chief financial officer with no qualifier, it is not, even if a search is under way.

What the filing tells you about the interim officer

Because Item 401(e) applies, an interim filing normally says what the person did over the past five years, and that usually shows whether the officer already worked at the company. Of the interim officers on the record whose origin the filing establishes, 80% were already at the company. See internal promotion or outside hire for how origin is read.

Two things an interim filing commonly includes, though no rule requires them:

  • A search. Many companies say they have begun, or will begin, a search for a permanent CFO. That sentence describes the company's plan as of the filing date and nothing more.
  • Extra pay. A stipend or award for the interim period is a compensatory arrangement, so if it is material, Item 5.02(c)(3) or Item 5.02(e) brings it into the filing. If the terms are not settled on filing day, Instruction 2 to Item 5.02 calls for an amendment within four business days after they are.

What an interim title does not change

The interim officer is the principal financial officer for every other purpose. Two consequences show up in later filings:

  • Certifications. Rule 13a-14(a) says each principal executive and principal financial officer "at the time of filing of the report must sign a certification." An interim CFO in office when a 10-Q or 10-K is filed signs the certifications for that report. See who signs the 10-K.
  • Named executive officer status. Item 402(a)(3)(ii) of Regulation S-K includes "all individuals serving as the registrant's principal financial officer or acting in a similar capacity during the last completed fiscal year," "regardless of compensation level." A company that had an interim CFO and then a permanent one during a fiscal year names both in its next Item 402 disclosure.

How the interim period ends

An interim appointment ends in one of a few ways, and each produces its own filing:

  • The interim officer is appointed permanently. The person is the same, but the appointment is new. When a company reports it, CFO Tribune records it as a separate move.
  • Someone else is appointed. The new CFO's filing usually says the interim officer will return to a prior role or leave.
  • The interim officer leaves. That is a departure under Item 5.02(b).

None of these has a deadline measured from the interim appointment. Neither the rules nor the record give a typical length for an interim period, and CFO Tribune does not estimate one.

Reading the interim share

The interim share is a count of filings, not a judgment about companies. A high share in a period means more companies reported an officer acting in the role, for whatever reasons their filings give. It does not show that those companies had trouble finding a CFO, and the record does not say so.

Three limits apply:

  • The record starts with filings from June 1, 2026, so the share describes that window, not the market's long-run history.
  • A company that skips the interim step and names a permanent successor in the same filing appears as a transition, not an interim. On the record, 168 moves are transitions.
  • A designation buried in a filing filed under another item, without Item 5.02, can be missed. Corrections are welcome through the corrections page.

Every interim record on the moves page quotes the filing's own words, so you can see exactly how the company described the appointment.
