[SCHEDULE 13D/A] Mill City Ventures III, Ltd. SEC Filing

Rhea-AI Filing Summary

Amendment No. 5 to Schedule 13D reports that CEO Douglas M. Polinsky now beneficially owns 680,762 Mill City Ventures III (MCVT) common shares—0.8 % of the outstanding class—falling below the 5 % threshold and triggering this exit filing. His holdings comprise 301,847 directly owned shares and 250,000 currently exercisable options, plus 128,915 shares held through Lantern Advisers, LLC. An additional 622,694 warrant shares are excluded because they are not exercisable within 60 days.

The change stems not from a sale by Mr. Polinsky but from dilution created by the company’s private placement that closed on 31 Jul 2025. The issuer sold 75.88 m shares at $5.42 and issued 7.14 m pre-funded warrants at $5.4199, lifting total shares outstanding to 81.94 m. Polinsky effected no transactions in the past 60 days.

Because his ownership is now below 5 %, this amendment constitutes the final update and exit of his Schedule 13D reporting obligations.

Positive

• Successful private placement closed on 31 Jul 2025 at $5.42 per share, injecting cash and potentially strengthening MCVT’s balance sheet.

Negative

• Massive dilution to 81.94 m shares outstanding cut insider ownership to 0.8 %, pressuring existing shareholders’ stakes.
• Insider exit from 13D reporting reduces future transparency into CEO trading activities.

Insights

Securities Analyst

TL;DR: Insider stake drops to 0.8 % due to large share issuance, signaling dilution; no shares sold.

The filing is largely mechanical: Polinsky’s percentage fell because MCVT issued ~83 m new securities, expanding the float nearly nine-fold. His absolute stake is unchanged, and he still holds substantial warrants, but his governance influence is now minimal. For investors, the bigger takeaway is the magnitude of dilution implied by the private placement, which may pressure per-share metrics. However, the $5.42 raise could bolster liquidity. Impact is modestly negative given dilution but tempered by fresh capital.

Corporate Governance Expert

TL;DR: Exit filing reduces insider reporting; board oversight may weaken but free-float rises.

With Polinsky below 5 %, mandatory 13D amendments cease, reducing transparency into his future trades. Insider alignment with minority shareholders diminishes, though broader ownership dispersion can enhance share liquidity and governance checks. No change in control intent is stated. Overall governance impact is neutral to slightly negative.

Footnote for entries 7, 8, 9, 10, 11: The reported figures are accurate as of the date of the event requiring the filing of this document, and remain accurate as of the date on which this document is filed. Footnote for entries 8, 10, 11: Consists of 128,915 shares of common stock of the issuer held by Lantern Advisers, LLC ("Lantern"). Lantern is controlled by Mr. Polinsky and Joseph A. Geraci, II, who share voting and dispositive power over the securities held by Lantern and therefore may be deemed to beneficially own the securities held by Lantern. Each of Messrs. Polinsky and Geraci disclaims beneficial ownership of the securities held by Lantern except to the extent of his individual pecuniary interest therein. Footnote for entry 13: As of the date on which this document is filed, the percentage of common stock of the issuer beneficially owned by Mr. Polinsky is 0.8% based on 81,944,398 shares of common stock of the issuer issued and outstanding, as disclosed in the issuer's Current Report on Form 8-K filed on July 31, 2025.

SCHEDULE 13D

Item 1.	Security and Issuer
(a)	Title of Class of Securities: COMMON STOCK, $0.001 PAR VALUE PER SHARE
(b)	Name of Issuer: Mill City Ventures III, Ltd
(c)	Address of Issuer's Principal Executive Offices: 1907 WAYZATA BOULEVARD, SUITE 205, WAYZATA, MINNESOTA , 55391.
Item 1 Comment: Explanatory Note On July 27, 2025, Mill City Ventures III, Ltd., a Minnesota corporation (the "issuer") entered into securities purchase agreements (the "Securities Purchase Agreements") with certain investors (the "Purchasers") pursuant to which the issuer agreed to sell and issue to the Purchasers in a private placement offering (the "Offering") an aggregate of (i) 75,881,625 shares of common stock (the "Shares") at an offering price of $5.42 per Share, and (ii) pre-funded warrants (the "Pre-Funded Warrants") to purchase up to an aggregate of 7,144,205 shares of common stock (the "Pre-Funded Warrant Shares") at an offering price of $5.4199 per Pre-Funded Warrant. Each of the Pre-Funded Warrants is exercisable for one share of common stock at an exercise price of $0.0001 per Pre-Funded Warrant Share. The Pre-Funded Warrants are immediately exercisable upon issuance, and may be exercised at any time until all of the Pre-Funded Warrants issued in the Offering are exercised in full. Each Purchaser's ability to exercise its Pre-Funded Warrants is subject to certain beneficial ownership limitations set forth therein. The Offering closed on July 31, 2025 and there were 81,944,398 shares of the issuer's common stock issued and outstanding following the Offering. This Amendment No. 5 to Schedule 13D relates to shares of common stock, par value $0.001 per share, of the issuer, and amends the initial statement on Schedule 13D dated February 17, 2009, Amendment No. 1 to Schedule 13D dated February 16, 2010, Amendment No. 2 to Schedule 13D dated February 14, 2011, Amendment No. 3 to Schedule 13D dated February 17, 2012, and Amendment No. 4 to Schedule 13D dated November 30, 2023 filed by Douglas M. Polinsky (the "reporting person"). This Amendment No. 5, together with the above-noted initial statement and its earlier amendments, are collectively referred to as the "Schedule 13D." Except as specifically provided herein, this Amendment No. 5 does not modify any of the information previously reported in the Schedule 13D. This Amendment No.5 is being filed to update the number of shares of common stock of the issuer, and the aggregate percentage of the common stock of the issuer, beneficially owned by the reporting person due to changes in outstanding common stock figures of the issuer resulting from the Offering, prior acquisitions of common stock of the issuer by the reporting person (as previously reported on Form 4 filings made with the SEC under Section 16 of the Securities Exchange Act of 1934, together with other filings of the issuer made on Form 10-Q, Form 10-K, and a proxy statement) (and which acquisitions did not require any amendment to the Schedule 13D), and not in connection with a disposition of any common stock by the reporting person. This Amendment No. 5 is the final amendment to the Schedule 13D and constitutes an exit filing for the reporting person, as the reporting person beneficially owns less than five percent of the common stock of the issuer.
