Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	The Company Sachem Capital Corp. (the “Company”), a New York corporation, specializes in originating, underwriting, funding, servicing and managing a portfolio of first mortgage loans. The Company operates its business as one segment. The Company offers short-term (i.e., one to three years), secured, non-bank loans to real estate owners and investors to fund their acquisition, renovation, development, rehabilitation or improvement of properties located primarily in the northeastern and southeastern sections of the United States. The properties securing the Company’s loans are generally classified as residential or commercial real estate and, typically, are held for resale or investment. Each loan is typically secured by a first mortgage lien on real estate and may also be secured with additional collateral, such as other real estate owned by the borrower or its principals, a pledge of the ownership interests in the borrower by the principals thereof, and/or personal guarantees by the principals of the borrower. The Company does not lend to owner occupants of residential real estate. The Company’s primary underwriting criterion is a conservative loan to value ratio. In addition, the Company may make opportunistic real estate purchases apart from its lending activities. Segment Reporting The Company uses the management approach to determine reportable operating segments. The Company operates through a single operating and reporting segment with an investment objective to generate both current income and capital appreciation through its investments in real estate mortgage loans and real estate. The management approach considers the internal organization and reporting used by the Company’s Chief Executive Officer, whom serves as the chief operating decision maker (“CODM”) for making decisions, allocating resources and assessing performance. The CODM assesses the performance and makes operating decisions of the Company on a consolidated basis primarily based on the Company’s net income. In addition to other factors and metrics, the CODM utilizes net income as a key determinant of the amount of dividends to be distributed to the Company's shareholders. As the Company’s operations comprise of a single reporting segment, the segment assets are reflected on the accompanying Consolidated Balance Sheets as “total assets” and the significant segment expenses are listed on the accompanying Consolidated Statements of Operations Contribution Agreement with Industrial Realty Group Global, LLC On May 17, 2026, the Company entered into a Contribution Agreement (the “Contribution Agreement”) with Industrial Realty Group Global, LLC, a Delaware limited liability company (“IRG Global”). The Contribution Agreement and the transactions contemplated thereby (the “Transaction”) were unanimously approved by the Board of Directors of the Company. Pursuant to the Contribution Agreement, IRG Global will contribute to IRG Realty Operating Partnership, L.P., a Delaware limited partnership to be formed as a subsidiary of the Company prior to the Closing (as defined below) (the “Operating Partnership”), 100% of the outstanding membership interests of IRG Master Holdings, LLC, a Delaware limited liability company (“IRG Master Holdings”), in exchange for (i) a number of common units of limited partnership interest in the Operating Partnership (“OP Units”) equal to the Transferee Consideration Units (as defined below) and (ii) a number of shares of Class B common stock of the Company (the “Class B Common Stock”) equal to the Transferee Consideration Units. IRG Master Holdings, together with its subsidiaries, owns and operates a portfolio of industrial real estate assets. Prior to the closing of the Transaction (the “Closing”), the Company will complete a series of pre-closing reorganization steps, including (i) forming the Operating Partnership and contributing all or substantially all of its assets thereto, (ii) redomesticating from the State of New York to the State of Delaware, (iii) effecting a 20-to-1 reverse stock split of all issued and outstanding Common Shares (as defined below), following which such shares will be redesignated as Class A common stock of the Company (the “Class A Shares”), (iv) authorizing a new class of Class B Common Stock (the “Class B Shares”), (v) adjusting the conversion and anti-dilution rights applicable to the issued and outstanding preferred stock of the Company in accordance with the applicable certificate of designations to reflect the reverse stock split, and (vi) changing its corporate name to “IRG Realty Trust, Inc.” The number of OP Units and Class B Shares to be issued to IRG Global at the Closing (the “Transferee Consideration Units”) will be calculated based on a formula set forth in the Contribution Agreement, subject to downward adjustment based on the aggregate shortfall in replacement value for any dispositions of IRG Master Holdings’ properties occurring during the Interim Period (as defined in the Contribution Agreement), other than dispositions with an aggregate shortfall of less than $3.0 million. The calculation of the Transferee Consideration Units was based on an assumed implied gross asset value of the IRG Global portfolio to be contributed of approximately $2.9 billion, with a net asset value of approximately $1.5 billion after approximately $1.4 billion of debt, and a deemed exchange value of the Company’s Common Shares at a price of $2.00 per share. Immediately following the Closing, IRG Global is expected to hold approximately 94.1% of the outstanding OP Units, with the Company retaining the remaining approximately 5.9% of the outstanding OP Units. Subject to certain restrictions, a holder of OP Units may require the Operating Partnership to exchange all or a portion of such holder’s OP Units for cash or, at the option of the Company, Class A Shares on a one-for-one basis, subject to the ownership, transfer, REIT qualification and other limitations set forth in the Operating Partnership Agreement (as defined below). The parties to the Contribution Agreement made representations and warranties customary for transactions of this type. The representations and warranties made under the Contribution Agreement do not survive the Closing. In addition, the parties made covenants customary for transactions of this type, including, among others, covenants providing for the conduct of each party’s business during the period between signing and Closing, including restrictions on specified actions without the other party’s consent, subject to customary exceptions. The Contribution Agreement may be terminated by either party under certain circumstances, including if the Closing has not occurred by April 30, 2027, subject to IRG Global’s one-time right to extend such date by up to 45 days in certain circumstances related to a pending arbitration matter, among other circumstances. At the Closing, the parties will execute and deliver or file, as applicable, among other things, the following (forms of which are included as exhibits to the Contribution Agreement): (i) a Tax Protection Agreement, pursuant to which the Company and the Operating Partnership will agree to certain restrictions on the disposition of the contributed properties and the maintenance of minimum liability allocations for the benefit of IRG Global and certain other protected unitholders; (ii) a Registration Rights Agreement, providing IRG Global with certain registration rights with respect to the Class A Shares issuable upon exchange of the OP Units, including shelf registration and underwritten demand rights, piggyback registration rights and block trade rights, in each case subject to a six-month lock-up period following the Closing; (iii) an Amended and Restated Limited Partnership Agreement of the Operating Partnership (the “Operating Partnership Agreement”); (iv) an Amended and Restated Certificate of Incorporation of the Company; (v) Amended and Restated Bylaws of the Company; and (vi) a Property Management Agreement related to the management of the properties contributed by IRG Global and its affiliates following the Closing. The Contribution Agreement also provides that, prior to the Closing, the parties will use commercially reasonable efforts to negotiate, finalize and, effective as of the Closing, execute a strategic services agreement with respect to the provision of certain services by IRG Global or one or more of its affiliates to the Company or one or more of its subsidiaries. Additional information regarding the Contribution Agreement and the Transaction is included in the Company’s Current Report on Form 8-K filed with the SEC on May 18, 2026.
