[424B3] Medicus Pharma Ltd. Prospectus Filed Pursuant to Rule 424(b)(3)

Rhea-AI Filing Summary

Medicus Pharma Ltd. (Nasdaq: MDCX) has entered into a warrant-inducement transaction designed to raise near-term cash and expand its future capital pool.

• Immediate cash: A single accredited holder agreed to exercise 1,340,000 existing $2.80 warrants, delivering approximately $3.75 million gross proceeds (closing expected 14 July 2025). Maxim Group will receive a 6 % cash fee.
• New leverage: In exchange, the holder will receive 2,680,000 five-year “New Warrants” at an exercise price of $3.75. Half the series includes a forced-exercise feature once the 10-day VWAP equals or exceeds $10.00.
• Protective terms: New Warrants contain customary anti-dilution adjustments and Black-Scholes value protection on fundamental transactions.
• Additional financing: Through two SEPA draws (9 & 14 July 2025) the company sold 490,000 shares to Yorkville at an average price of $3.10, raising $1.52 million earmarked partly for debenture pre-payment.
• Use of proceeds: funds will support ongoing clinical trials, working capital and the pending acquisition of Antev Limited.
• Listing/Capital structure: Common shares and $4.64 Public Warrants continue to trade under MDCX and MDCXW. The inducement and SEPA transactions add up to 4.51 million potential new shares, increasing prospective dilution.

Medicus remains an emerging growth company and intends to register New Warrant shares within 120 days.

Positive

• ~$5.3 million gross cash infusion strengthens near-term liquidity for trials and acquisition costs
• Forced-exercise clause could accelerate additional capital if share price exceeds $10, signalling management confidence
• Anti-dilution and Black-Scholes protections reduce warrant holder uncertainty, potentially facilitating future capital access

Negative

• Issuance of 2.68 million new warrants and 490 k SEPA shares materially increases potential dilution
• 6 % placement fee and other transaction costs reduce net proceeds
• Reliance on exempt, unregistered securities may widen bid-ask spreads and create resale pressure once shares are registered

Insights

Financial Analyst

TL;DR: Raises $5.3 M gross capital, but issues 2.68 M dilutive warrants; cash extends runway yet equity overhang persists.

Capital impact: The $3.75 M warrant exercise plus $1.52 M SEPA proceeds provide roughly $5.27 M gross liquidity, a meaningful boost for an R&D-stage company with continuous cash burn.
Dilution: New Warrants (+2.68 M) and SEPA shares (+0.49 M) enlarge the fully-diluted share count by up to 10 % versus the latest 32 M shares outstanding, creating an overhang that could cap near-term price appreciation.
Pricing: Setting the New Warrant strike at $3.75 (24 % above the $3.03 spot) balances investor upside with company cost of capital. The $10 forced-exercise trigger could accelerate cash inflow if clinical catalysts drive the stock materially higher.
Use of funds: Directing proceeds to clinical programs and the Antev acquisition aligns with stated strategy, potentially de-risking pipeline milestones.
Outlook: Net effect is neutral: liquidity improves, but dilution and dependence on warrant holders remain.

​Item 1.01. Entry into a Material Definitive Agreement.

Warrant Inducement Agreement

On July 14, 2025, Medicus Pharma Ltd. (the "Company") entered into an inducement offer (the "Agreement") with a certain accredited and institutional holder (the "Holder") to exercise existing warrants to purchase up to 1,340,000 of the Company's common shares ("Common Shares") issued on March 10, 2025 and with an exercise price of $2.80 per Common Share (the "Existing Warrants"). Pursuant to the Agreement, the Holder, upon exercise, will receive new unregistered warrants (the "New Warrants") to purchase up to 2,680,000 Common Shares upon the exercise of the New Warrants (the "New Warrant Shares"), pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended ("Securities Act").

The New Warrants, which will be issued in two series, each containing 50% of the New Warrants, will have an exercise price of $3.75 per Common Share, will be exercisable following the date of issuance and will expire on the five-year anniversary of such date. In addition, one of the series of New Warrants will contain a right for the Company to force the Holder to exercise such New Warrants, subject to certain conditions described in the New Warrants, in the event that the average VWAP of the Common Shares during any ten (10) Trading Day period shall equal or exceed $10.00. The exercise price and the number of New Warrant Shares issuable upon exercise of each New Warrant are subject to appropriate adjustments in the event of certain share dividends and distributions, share splits, share consolidations, reclassifications or similar events affecting the Common Shares. In addition, in certain circumstances, upon a fundamental transaction (as defined in the New Warrants), a holder of New Warrants will be entitled to receive, upon exercise of the New Warrants, the kind and amount of securities, cash or other property that such holder would have received had they exercised the New Warrants immediately prior to the fundamental transaction. Additionally, as more fully described in the New Warrants, in the event of certain fundamental transactions, the holders of the New Warrants will be entitled to receive consideration in an amount equal to the Black Scholes value of the New Warrants on the date of consummation of the transaction.

The closing is expected to take place on or about July 14, 2025, subject to satisfaction of customary closing conditions. Gross proceeds to the Company from the exercise of the Existing Warrants is expected to be approximately $3.75 million, prior to deducting placement agent fees as further described below. The Company intends to use the net proceeds from the offering for ongoing clinical trials, working capital and general corporate purposes, which includes costs associated with the Company's agreement to acquire Antev Limited.

The issuance of the Common Shares underlying the Existing Warrants will be qualified pursuant to the Company's Offering Statement on Form 1-A (File No. 024-12573).

The Company agreed in the Agreement to file a registration statement on Form S-1 with the Securities and Exchange Commission (the "SEC") providing for the resale of the New Warrant Shares as soon as practicable, and in any event within one-hundred and twenty (120) calendar days of the date of the Agreement (the "Initial Filing Date), and to use commercially reasonable efforts to have such registration statement declared effective by the SEC on or prior to the thirtieth (30) calendar day after the Initial Filing Date. Pursuant to the Agreement, the Company shall use commercially reasonable efforts to keep such registration statement effective at all times until the original holder of the New Warrants may sell its New Warrant Shares without volume or manner of sale limitation under Rule 144.

In connection with the transactions contemplated in the Agreement, the Company agreed to pay its inducement agent, Maxim Group, LLC, a cash fee equal to 6.0% of the gross proceeds received by the Company in the transactions contemplated by the Agreement.

The foregoing descriptions of the New Warrants and Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the New Warrants and the Agreement, forms of which are attached to this Current Report on Form 8-K as Exhibits 4.1 and 10.1, respectively.

Item 3.02 Unregistered Sales of Equity Securities.

The disclosure regarding the Existing Warrants, New Warrants and the New Warrant Shares set forth under Item 1.01 is incorporated by reference into this Item 3.02. The Company expects to issue the New Warrants in reliance on the exemption from the registration requirements of the Securities Act, provided by Section 4(a)(2) under the Securities Act in a transaction not involving a public offering. Neither the New Warrants nor the New Warrant Shares have been registered under the Securities Act, and such securities may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws.

In addition, on July 9, 2025 and July 14, 2025, pursuant to the previously disclosed Standby Equity Purchase Agreement (the "SEPA") dated February 10, 2025 between Medicus Pharma Ltd. (the "Company") and YA II PN, Ltd. ("Yorkville"), the Company sold 155,000 Common Shares to Yorkville for approximately $3.2841 per share, or approximately $509,000 in consideration and 335,000 Common Shares to Yorkville for approximately $3.0216 per share, or approximately $1,012,000 in consideration, respectively (together, the "SEPA Advances"). The Company sold, in the aggregate, 490,000 Common Shares to Yorkville through the SEPA Advances and received aggregate net proceeds of approximately $1,521,000. The Company may cause Yorkville to purchase additional Common Shares under the SEPA from time to time, subject to the satisfaction or waiver of the conditions and limitations set forth in the SEPA. The Company intends to use part of the net proceeds from the SEPA Advances to prepay a portion of the debentures the Company has outstanding with Yorkville, as described in that certain Current Report on Form 8-K dated June 20, 2025. The Common Shares were issued and sold to Yorkville in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act") afforded by Section 4(a)(2) of the Securities Act. The Company is relying on this exemption from registration based in part on representations made by Yorkville in the SEPA. Yorkville may resell the Common Shares it has purchased from the Company under the SEPA from time to time pursuant to that certain effective registration statement on form S-1 (File No. 333-287582), which has been filed by the Company in accordance with its requirements under the SEPA.

This report shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
