PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Arboretum Silverleaf Income Fund, L.P. (the “Partnership”) is unable, without unreasonable effort or expense, to file its Quarterly Report on Form 10-Q for the period ended June 30, 2026 (the “Form 10-Q”) by its due date for the reasons discussed in this Form 12b-25.

As previously reported in its Notification of Late Filing on Form 12b-25 filed with the SEC on March 31, 2026, and as previously reported in its Notification of Late Filing on Form 12b-25 filed with the SEC on November 14, 2025, and as previously reported in its Notification of Late Filing on Form 12b-25 filed with the SEC on August 14, 2025, and as previously reported in its Notification of Late Filing on Form 12b-25 filed with the SEC on May 16, 2025, the Partnership was unable to file its Quarterly Report on Form 10-Q for the periods ended September 30, 2025, June 30, 2025 and March 31, 2025 and its Annual Report on Form 10-K (the “Form 10-K”) for the year ended December 31, 2025, within the prescribed time period due to the Partnership’s termination of its previous independent registered public accounting firm as the independent registered public accounting firm of the Partnership, effective April 1, 2026, as previously disclosed on Form 8-K filed on April 7, 2026. As a result of that resignation, the Partnership is unable to file its Form 10-Ks and its Form 10-Qs by its due date without unreasonable effort or expense. As previously disclosed on Form 8-K filed on April 7, 2026, the Partnership engaged Stephano Slack LLC (“Stephano Slack”) as the Partnership’s independent registered public accounting firm to perform the audit of the Partnership’s 2025 annual financial statements (Form 10-K) and reviews of the Partnership’s Form 10-Qs for the periods ended March 31, 2025, June 30, 2025 and September 30, 2025, March 31, 2026 and June 30, 2026, the Partnership requires additional time to complete the procedures necessary to file its annual report on Form 10-K and Form 10-Qs, and accordingly, the Form 10-Q for the period ended June 30, 2026 is delayed.

The Partnership is working diligently to complete and file the Form 10-Q as soon as practicable. However, given the time and focus dedicated to the Partnership’s completion of the audit of its 2025 annual financial statements (Form 10-K) and reviews of the Partnership’s Form 10-Qs for the periods ended March 31, 2025, June 30, 2025, September 30, 2025, March 31, 2026 and June 30, 2026, the Partnership is necessarily delayed in its reporting and review process for the period ended June 30, 2026. As a result, the Partnership does not expect to complete the preparation and filing of the Form 10-Q on or before the fifth calendar day following the prescribed due date. Additional time is needed for the new independent registered public accounting firm to complete the audit and interim reviews. The Partnership is currently working diligently to file the Form 10-K and 10-Qs as promptly as practicable, however, the Partnership is currently unable to estimate the timing for the filing of such forms.
