Item 3.02 Unregistered Sales of Equity Securities.

As previously disclosed, on

October 24, 2025, MultiSensor AI Holdings, Inc. (the “Company”) entered into a securities purchase agreement with

certain investors (collectively, the “Investors”), pursuant to which the Company sold to the Investors shares of the Company’s

common stock, par value $0.0001 per share (the “Common Stock”), and warrants (the “Warrants”) to purchase up to

an aggregate of 68,459,652 shares of Common Stock at an exercise price of $0.409 per share. Pursuant to the Warrants, the exercise price

and number of shares of Common Stock issuable upon exercise of the Warrants proportionately adjust upon the occurrence of a share split,

reverse share split, share dividend, share combination recapitalization or other similar transaction involving the Company’s Common

Stock (each, a “Share Combination Event”), and if the lowest daily volume weighted average price of the Company’s Common

Stock during the five trading days immediately following such event (the “Share Combination Adjustment Period” and such price

the “Event Market Price”), is less than the current exercise price of the Warrants, the exercise price will be reduced (but

in no event increased) to the Event Market Price and the number of shares of Common Stock issuable upon exercise will be proportionately

increased such that the aggregate exercise price of the Warrants will be equal to the aggregate exercise price payable under the Warrants.

Notwithstanding the foregoing, the exercise price shall not be reduced below $0.14944 per share ($5.9776 following the Reverse Stock Split

(as defined below)).

On April 8, 2026, the

Company filed a Certificate of Amendment with the Secretary of State of the State of Delaware to effect the reverse stock split at a ratio

of 1-for-40 (the “Reverse Stock Split”). The Reverse Stock Split became effective at 12:01 a.m. Eastern Time on April 13,

2026, at which time every forty shares of the Company’s then issued and outstanding Common Stock automatically converted into one

share of Common Stock, without any change in the par value per share.

As a result of the Reverse

Stock Split and following the resulting Share Combination Adjustment Period, the exercise price of the Warrants was readjusted to $5.98

per share and the total number of shares of Common Stock issuable upon exercise of the Warrants was proportionately increased to 4,682,273.85

shares of the Company’s Common Stock, effective as of the close of trading on April 17, 2026.

SIGNATURE

Pursuant to the requirements of the Securities

Exchange Act of 1934, as amended, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly

authorized.
