Exhibit 4.70

EXCLUSIVE RIGHT AND OPTION AGREEMENT

This Exclusive Right and Option Agreement (this “Agreement”) is made and entered into as of November 21, 2025, between Evangelos J. Pistiolis, (the “Seller”) and Top Ships Inc., a Marshall Islands corporation (the “Buyer”). The Seller and the Buyer may be referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, the Seller owns certain properties that have been completed or are under construction in Dubai, United Arab Emirates, details of which are set forth in Schedule A hereto (each, a “Property”, all together the Properties) with an aggregate estimated market value in excess of $200.0 million;

WHEREAS, the Buyer is considering investing in real estate and has identified the United Arab Emirates, Dubai in particular, as a market of interest for an initial investment in real estate, has reviewed the Properties, and would like to enter into due diligence and potential negotiations with the Seller for the acquisition of one or more assets from the Properties (the “Acquisition”); and

WHEREAS, the Parties intend for this Agreement to constitute a legally binding and enforceable contract between them.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

In consideration of the Option Fee (as defined in Section 2), the Seller hereby grants to the Buyer the exclusive right and irrevocable option (the “Option”) to acquire one or more Properties from the Seller at a discount of 10% of the fair market value as determined pursuant to Section 5 hereto. For any Properties under construction, this includes the right to step into the Seller’s position for the purpose of executing and performing any construction contracts, the issuance of one or more refund guarantees or bonds, if applicable, in favor of the Buyer, and to take assignment or novation of any related financing arrangements with respect to the Properties, at the Buyer’s further option.

Prior to (i) the expiration of the Option Period, if the Option is not exercised by the Buyer, or (ii) in the event the Option is exercised, the consummation of the Acquisition, the Seller covenants that it shall:

In consideration for the grant of the Option, the Buyer shall, pay to the Seller the sum of $23,500,000 (the “Option Fee”) by wire transfer to a bank account designated by the Seller prior to each instalment.

The Option Fee is payable as follows:

The date upon which the full Option Fee has been paid to the Seller shall be the “Effective Date.”

If the full Option Fee is not paid by December 31, 2025, this Agreement shall be terminated without any recourse by either party, provided that, any instalments of the Option Fee that have been paid to the Seller shall be returned to the Buyer by January 5, 2026.

Upon the Buyer’s exercise of the Option in accordance with Section 3, the Option Fee shall be non-refundable and shall be applied as a deposit toward the final Purchase Price (as defined in Section 5). For the avoidance of doubt, if the final Purchase Price is less than the Option Fee, any difference will be refunded to the Buyer within five (5) business days after closing.

If the Option expires without being exercised by the Buyer, the Seller shall refund the Option Fee in full to the Buyer within five (5) business days of the expiration of the Option Period.

The Option shall be exercisable by the Buyer at any time during the period from the Effective Date and ending on the earlier of (a) 90 days thereafter or (b) the exercise by the Buyer of the Option with respect to any Property (the “Option Period”). For the avoidance of doubt, the exercise of the Option shall only be permitted once and there shall be no further Option in respect of Properties for which the Option was not exercised.

To exercise the Option, the Buyer must deliver unconditional and irrevocable written notice of exercise to the Seller prior to the expiration of the Option Period.

Following the delivery of a notice, the Buyer must close the transaction within 60 business days unless otherwise agreed between the parties.

The Seller hereby agrees that during the Option Period, the Seller will not sell, transfer, assign, or otherwise encumber his rights relating to any Property or construction contract or similar agreement relating any Property under construction or the Buyer’s rights under this Option (or engage in any transaction substantially similar in effect to any of the foregoing) (each sale or disposition, an “Alternative Transactions”). During the Option Period, the Seller agrees to promptly advise the Buyer, in writing if it receives any proposal regarding an Alternative Transaction from a bona fide third party, including all material terms of such proposal.

The Buyer, at its option, may decide to waive its rights under Section 4.1 above, in relation to any of the Properties, provided that, upon the closing of any Alternative Transaction in respect of any such Property, the Seller agrees to pay to the Buyer a fee (a “Waiver Fee”) equal to the greater of (a) $200,000 or (b) 50% of the Net Sale Profit from such Alternative Transaction with respect to each such Property.

For the purposes of this Section 4.2, “Net Sale Profit” means the gross sale price and all other consideration paid for one or more of the Properties subject to such Alternative Transaction, less (a) (i) net prorations which reduce the cash due at closing from the purchaser, if there is such a reduction, (ii) customary closing costs, including legal or deed preparation fees paid by the Seller to third parties unaffiliated with the Seller, (iii) any governmental transfer taxes or similar taxes or fees paid by the Seller and (iv) brokerage commissions paid by the Seller to third party brokers unaffiliated with the Seller and (b) the Property Cost Basis. For the avoidance of doubt, for purposes of determining the portion of the Net Sale Profit, the gross sale price shall include the amount of any purchase money financing extended by the Seller to the purchaser as if paid in cash at closing.

“Property Cost Basis” shall mean the total capital invested by the Seller to acquire and improve each Property, calculated as the sum of the following documented costs:

(a) The full purchase price paid to the seller or builder for the Property plus any brokerage commissions paid by the Seller to third party brokers unaffiliated with the Seller;

(b) All direct and necessary costs incurred to acquire legal title to the Property, including but not limited to governmental transfer taxes, registration fees, title search and insurance costs, and legal fees directly attributable to the acquisition; and

(c) The cost of all capital improvements made to the Property after its acquisition. A “capital improvement” is an expenditure that materially increases the Property’s value, significantly extends its useful life, or adapts it to a new use, as distinguished from routine maintenance, repairs, or cosmetic updates.

The total purchase price for the Acquisition (the “Purchase Price”) shall be an amount equal to the

fair market value of any Properties upon which an Option has been exercised, discounted by 10%. Such fair market value shall be determined by calculating the average of two independent real estate appraiser valuations, both appraisers, to be mutually agreed upon by the Parties.

Upon the Buyer’s exercise of the Option, the Seller shall, at the Buyer’s expense, provide full and timely cooperation to effectuate the Acquisition. This shall include, without limitation:

The Parties expressly acknowledge and agree that this Agreement is not a mere expression of intent, but constitutes a legally binding and enforceable contract. Each Party has the full legal right, power, and authority to enter into and perform its obligations under this Agreement.

The existence and terms of this Agreement shall be kept strictly confidential by the Parties, except as may be required by law, regulations or rules of any stock exchange on which the Buyer’s equity is listed, or to obtain necessary consents from third parties.

This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior negotiations, understandings, and agreements.
