Item 8.01 Other Events

As previously disclosed, on February 19, 2026, common stock purchase warrants previously issued by Wheeler Real Estate Investment Trust, Inc. (the "Company") to certain affiliates of Magnetar Financial LLC (together, the "Investors") were amended and restated (as so amended, the "A&R Warrants").

The A&R Warrants are exercisable, in whole or in part (and at any time), for an aggregate number of shares of the Company's common stock, $0.01 par value per share (the "Common Stock") representing 12% of the Common Stock outstanding on the date of any exercise (less the aggregate number of shares of Common Stock previously issued as a result of any partial exercise) at an exercise price of $0.01 per share.

The A&R Warrants expire on March 27, 2026.

The A&R Warrants were exercised in whole on March 24, 2026. Accordingly, the Company issued the Investors the number of shares of Common Stock opposite their names in the table below:

Investor			Percentage			Numbers of Shares of Common Stock Issued
Magnetar Structured Credit Fund LP			3.356		%	48,124
Magnetar Longhorn Fund LP			0.523		%	7,499
Magnetar Lake Credit Fund LLC			3.610		%	51,766
Purpose Alternative Credit Fund - F LLC			3.382		%	48,497
Purpose Alternative Credit Fund - T LLC			1.129		%	16,189
Total			12.000		%	172,075

The shares of Common Stock issued to the Investors are registered shares pursuant to the Company's registration statement on Form S-11 (File No. 333-294263), which was declared effective on March 20, 2026.

As a result of these exercises, there are no outstanding warrants in the Company's capital table.
