Item 1.01 Entry into a Material Definitive Agreement

On September 19, 2025, Whitestone REIT (the “Company”), through its operating partnership, Whitestone REIT Operating Partnership, L.P. (the “Operating Partnership”), entered into an unsecured credit facility (the “2025 Facility”) pursuant to that certain Fourth Amended and Restated Credit Agreement (the “A&R Credit Agreement”), dated September 19, 2025, by and among the Operating Partnership, the Guarantors from time to time parties thereto, the several financial institutions from time to time party thereto and Bank of Montreal, as administrative agent (the “Administrative Agent”). The A&R Credit Agreement amends and restates that certain Third Amended and Restated Credit Agreement, dated September 16, 2022 with the Administrative Agent, and the other agents and lenders named therein (as amended, restated, supplemented or otherwise modified prior to September 19, 2025, the “Existing Credit Agreement”).

The 2025 Facility is comprised of the following two tranches:

●

$375.0 million unsecured revolving credit facility with a maturity date of September 19, 2029, with two six-month options to extend the maturity date to September 19, 2030 (the “Revolver”); and

●

$375.0 million unsecured term loan with a maturity date of January 31, 2031 (“Term Loan”).

Borrowings under the 2025 Facility accrue interest (at the Operating Partnership’s option) at a Base Rate or Term SOFR plus an applicable margin based upon the Company’s then existing leverage. Based on the Company’s current leverage ratio, the Revolver has an initial interest rate of Term SOFR plus 1.40%. In addition, the Company entered into interest rate swaps to fix the Term SOFR rates on the Term Loan. The Term Loan has the following interest rates:

●

3.40% (Term SOFR) plus 1.35% (current applicable margin) through September 30, 2026

●

3.36% (Term SOFR) plus 1.35% (current applicable margin) from October 1, 2026 through January 31, 2028

●

3.42% (Term SOFR) plus 1.35% (current applicable margin) from February 1, 2028 through January 31, 2031

Base Rate means, for any day, the highest of: (a) the Administrative Agent’s prime commercial rate, (b) the sum of (i) the rate per annum equal to the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System, as published by the Federal Reserve Bank of New York for such day, plus (ii) 0.50%, or (c) the sum of (i) Term SOFR for a one-month tenor in effect on such day plus (ii) 1.10%. Term SOFR means, for any such day, the SOFR-based term rate for the day two (2) business days prior.

The A&R Credit Agreement contains substantially similar terms to the Existing Credit Agreement. Other material terms, including financial covenants, were not changed by the A&R Credit Agreement, except as follows:

●

a 10 basis point credit spread adjustment previously applied to SOFR-based loans was eliminated;

●

the maturity date for both the Revolver and the Term Loan were extended to the maturity dates described above;

●

the interest rates were adjusted as described above; and

●

the unused fee applicable to the Revolver was reduced by 5 basis points in instances where the average daily unused commitments are less than 50% of the total revolving commitments.

At closing, the Company used (i) approximately $83.2 million of proceeds from the Term Loan to repay amounts outstanding under its previous unsecured revolving credit facility, (ii) $285 million of proceeds from the Term Loan to refinance in full the Company’s Term Loan and (iii) approximately $6.8 million from the Term Loan towards fees and expenses related to the A&R Credit Agreement.

The foregoing description of the 2025 Facility does not purport to be complete and is qualified in its entirety by the terms of the 2025 Facility, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
