Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On February 18, 2020, the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market (“Nasdaq”) provided written notice to Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) that it is not in compliance with the continued listing standard set forth in Nasdaq Listing Rule 5705(b)(9)(B)(i)(c) with respect to a series of the Trust. Listing Rule 5705(b)(9)(B)(i)(c) requires that, in order to comply with Nasdaq continued listing standards, a listed company (such as a series of the Trust) must maintain a minimum of 50 beneficial shareholders following the initial twelve-month period after commencement of trading on Nasdaq of a series of Index Fund Shares. Invesco RAFI^TM Strategic Developed ex-US Small Company ETF (Nasdaq Symbol: ISDS) (the “Fund”), a series of the Trust, was reported to have less than 50 beneficial shareholders as of February 11, 2020.

In accordance with Nasdaq procedures, the Trust may submit a written response to the Staff outlining the Trust’s plan to regain compliance with Listing Rule 5705(b)(9)(B)(i)(c). The Trust intends to submit such a response in a timely manner. If the Staff accepts the Trust’s plan to regain compliance, the Staff will grant an extension of up to 180 calendar days from the date of the Staff’s letter (February 18, 2020) for the Trust to evidence compliance (the “Extension Date”). In order for the Fund to regain compliance, the Trust will be required to demonstrate that it has at least 50 beneficial shareholders as of the Extension Date. If the Trust is unable to demonstrate that the Fund has at least 50 beneficial shareholders as of the Extension Date, the Staff may de-list the Fund. Alternatively, if the Trust does not submit the written response outlining its plan to regain compliance, or if the Staff does not accept the Trust’s plan to regain compliance, the Staff may de-list the Fund.
