Business and Organization

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Note 1—Business and Organization Business The Company operates its business through one reportable segment by acquiring, managing and capitalizing ground leases. The Company also manages entities focused on ground leases (refer to Note 7) and a wholly-owned subsidiary of the Company serves as external manager to Star Holdings (“Star Holdings”), a Maryland statutory trust that holds the legacy non-ground lease assets previously held by iStar. Ground leases are long-term contracts between the landlord (the Company) and a tenant or leaseholder. Ground leases generally represent ownership of the land underlying commercial real estate projects that is net leased by the fee owner of the land to the owners/operators of the real estate projects built thereon (“Ground Leases”). Under a Ground Lease, the tenant is generally responsible for all property operating expenses, such as maintenance, real estate taxes and insurance and is also responsible for development costs and capital expenditures. Ground Leases are typically long-term (base terms ranging from 30 The Company intends to target investments in long-term Ground Leases in which: (i) the initial cost of its Ground Lease represents 30% to 45% of the combined value of the land and buildings and improvements thereon as if there was no Ground Lease on the land (“Combined Property Value”); (ii) the ratio of property net operating income to the Ground Lease payment due the Company (“Ground Rent Coverage”) is between 2.0x to 4.5x, and for this purpose the Company uses estimates of the stabilized property net operating income if it does not receive current tenant information and for properties under construction or in transition, in each case based on leasing activity at the property and available market information, including leasing activity at comparable properties in the relevant market; and (iii) the Ground Lease contains contractual rent escalation clauses or percentage rent that participates in gross revenues generated by the commercial real estate on the land. As Ground Lease lessor, the Company typically has the right to regain possession of its land and take ownership of the buildings and improvements thereon upon tenant default and the termination of the Ground Lease on account of such default. The Company believes that the Ground Lease structure provides an opportunity for potential value accretion through the reversion to the Company, as the Ground Lease owner, of the buildings and improvements on the land at the expiration or earlier termination of the lease, for no additional consideration from the Company. Prior to the Merger, Old SAFE was managed by SFTY Manager, LLC (the “Former Manager”), a wholly-owned subsidiary of iStar, pursuant to a management agreement. Old SAFE had no employees, as the Former Manager provided all services to it. Old SAFE relied on the extensive investment origination and sourcing platform of its Former Manager to actively promote the benefits of the Ground Lease structure to prospective Ground Lease tenants. Subsequent to the Merger, the Company is internally managed. Organization As part of a restructuring in connection with the Merger (the “Caret Restructuring”), Safehold Operating Partnership LP converted into a Delaware limited liability company and renamed itself “Safehold GL Holdings LLC” (“Portfolio Holdings”), with the Company as its managing member. The Company conducts all of its business and owns all of its properties through Portfolio Holdings. In addition, holders of Caret units in Old SAFE’s subsidiary, Caret Ventures LLC (“Caret Ventures”), contributed their interests in Caret Ventures to Portfolio Holdings in return for Caret units issued by Portfolio Holdings. Following the restructuring, 100% of the equity interests in Caret Ventures is held by Portfolio Holdings. The Company, management of the Company, employees and former employees of the Company, affiliates of MSD Partners (as defined below) and other outside investors own the issued and outstanding equity of Portfolio Holdings. ​ Merger Transaction The Company considered the following relevant facts for this determination: ● At the time of the Merger closing, Old SAFE shareholders, excluding the Old SAFE shares held directly by iStar, members of iStar management and Star Holdings, control a majority of the voting interests in the Company and the combined company operates under the name “Safehold Inc.;” ​ ● The composition of the combined company’s board of directors, which includes three directors from Old SAFE, two directors from iStar, and two management members of both Old SAFE and iStar; ​ ● Old SAFE was the larger entity by size when comparing the key metrics of total assets, total revenue and net income (loss) from continuing operations and allocable to common shareholders; and ​ ● Substantially all of the assets and liabilities of the Company consist of the historical assets and liabilities of Old SAFE, and the go-forward business plan of the Company is to conduct the Ground Lease business conducted by Old SAFE prior to the Merger. ​ As a result, the historical financial statements of Old SAFE become the historical financial statements of the Company. Immediately before the closing of the Merger, iStar separated its remaining legacy non-ground lease assets and businesses, approximately $50.0 million of cash, exclusive of working capital reserves and restricted cash, and approximately 13.5 million shares of Old SAFE common stock into Star Holdings by distributing to iStar’s stockholders, on a pro rata basis, the issued and outstanding equity interests of Star Holdings (the “Spin-Off”). ​ Other Merger related transactions ​ On August 10, 2022, iStar entered into an agreement (the “MSD Stock Purchase Agreement”) with MSD Partners, L.P. (“MSD Partners”) pursuant to which MSD Partners agreed to purchase 5,405,406 shares of Old SAFE’s common stock then owned by iStar (the “MSD Stock Purchase”) for an aggregate purchase price of approximately $200 million, or $37.00 per share, payable in cash. MSD Partners’ rights and obligations under the MSD Stock Purchase Agreement were subsequently assigned to certain of its affiliates. The MSD Stock Purchase closed on March 31, 2023, shortly before the closing of the Merger. MSD Partners has the right to designate an observer to the board of directors of the Company, a top-up right on future equity issuances (subject to certain exceptions) and registration rights. MSD Partners is subject to a customary standstill and certain restrictions on sales of its shares of the Company’s common stock. On August 10, 2022, MSD Partners also agreed to purchase 100,000 Caret units (refer to Note 12) from the Company for an aggregate purchase price of $20.0 million (the “MSD Caret Purchase”). MSD Partners received a credit against their purchase price for Caret units equal to the amount they would have received had they held Caret units at the time of a December 2022 distribution to other Caret unit holders, which was equal to $0.6 million. MSD Partners’ rights and obligations under the purchase agreement were subsequently assigned to certain of its affiliates. The closing of the MSD Caret Purchase took place in conjunction with the closing of the Merger on March 31, 2023. ​ Star Holdings was capitalized in part with an 8.0%, four-year term loan from the Company having an initial principal amount of $115.0 million, as well as SOFR plus 3.00% bank debt with an initial principal balance of $140.0 million from Morgan Stanley Bank, N.A. which is secured by approximately 13.5 million shares of the Company (refer to Note 6). In connection with the Spin-Off, Safehold Management Services Inc. (“SpinCo Manager”), a Delaware corporation and a subsidiary of the Company, entered into a management agreement with Star Holdings effective as of March 31, 2023, pursuant to which SpinCo Manager will continue to operate and pursue the orderly monetization of Star Holding’s assets. Star Holdings paid SpinCo Manager an annual management fee of $25.0 million for the term ended March 31, 2024, and will pay an annual fee of $15.0 million for the term ended March 31, 2025. The annual fee declines to $10.0 million and $5.0 million, respectively, for each of the following annual terms, and adjusts to 2.0% of the gross book value of Star Holdings’ assets, excluding shares of the Company’s common stock, thereafter. The Company and Star Holdings also entered into a governance agreement that places certain restrictions on the transfer and voting of the shares of the Company owned by Star Holdings, and a registration rights agreement under which the Company agreed to register such shares for resale in accordance with applicable securities laws. ​ Note 2—Basis of Presentation and Principles of Consolidation Basis of Presentation The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. In the opinion of management, the accompanying consolidated financial statements contain all adjustments consisting of normal recurring adjustments necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year. Principles of Consolidation Consolidated VIEs The classifications of these assets are primarily within “Net investment in sales-type leases,” “Real estate, net,” “Real estate-related intangible assets, net” and “Deferred operating lease income receivable” on the Company’s consolidated balance sheets. The classifications of liabilities are primarily within “Debt obligations, net” and “Accounts payable, accrued expenses and other liabilities” on the Company’s consolidated balance sheets. The liabilities of these VIEs are non-recourse to the Company and can only be satisfied from each VIE’s respective assets.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Note 1—Business and Organization Business The Company operates its business through one reportable segment by acquiring, managing and capitalizing ground leases. The Company also manages entities focused on ground leases (refer to Note 7) and a wholly-owned subsidiary of the Company serves as external manager to Star Holdings (“Star Holdings”), a Maryland statutory trust that holds the legacy non-ground lease assets previously held by iStar. Ground leases are long-term contracts between the landlord (the Company) and a tenant or leaseholder. Ground leases generally represent ownership of the land underlying commercial real estate projects that is net leased by the fee owner of the land to the owners/operators of the real estate projects built thereon (“Ground Leases”). Under a Ground Lease, the tenant is generally responsible for all property operating expenses, such as maintenance, real estate taxes and insurance and is also responsible for development costs and capital expenditures. Ground Leases are typically long-term (base terms ranging from 30 The Company intends to target investments in long-term Ground Leases in which: (i) the initial cost of its Ground Lease represents 30% to 45% of the combined value of the land and buildings and improvements thereon as if there was no Ground Lease on the land (“Combined Property Value”); (ii) the ratio of property net operating income to the Ground Lease payment due the Company (“Ground Rent Coverage”) is between 2.0x to 4.5x, and for this purpose the Company uses estimates of the stabilized property net operating income if it does not receive current tenant information and for properties under construction or in transition, in each case based on leasing activity at the property and available market information, including leasing activity at comparable properties in the relevant market; and (iii) the Ground Lease contains contractual rent escalation clauses or percentage rent that participates in gross revenues generated by the commercial real estate on the land. As Ground Lease lessor, the Company typically has the right to regain possession of its land and take ownership of the buildings and improvements thereon upon tenant default and the termination of the Ground Lease on account of such default. The Company believes that the Ground Lease structure provides an opportunity for potential value accretion through the reversion to the Company, as the Ground Lease owner, of the buildings and improvements on the land at the expiration or earlier termination of the lease, for no additional consideration from the Company. Prior to the Merger, Old SAFE was managed by SFTY Manager, LLC (the “Former Manager”), a wholly-owned subsidiary of iStar, pursuant to a management agreement. Old SAFE had no employees, as the Former Manager provided all services to it. Old SAFE relied on the extensive investment origination and sourcing platform of its Former Manager to actively promote the benefits of the Ground Lease structure to prospective Ground Lease tenants. Subsequent to the Merger, the Company is internally managed. Organization As part of a restructuring in connection with the Merger (the “Caret Restructuring”), Safehold Operating Partnership LP converted into a Delaware limited liability company and renamed itself “Safehold GL Holdings LLC” (“Portfolio Holdings”), with the Company as its managing member. The Company conducts all of its business and owns all of its properties through Portfolio Holdings. In addition, holders of Caret units in Old SAFE’s subsidiary, Caret Ventures LLC (“Caret Ventures”), contributed their interests in Caret Ventures to Portfolio Holdings in return for Caret units issued by Portfolio Holdings. Following the restructuring, 100% of the equity interests in Caret Ventures is held by Portfolio Holdings. The Company, management of the Company, employees and former employees of the Company, affiliates of MSD Partners (as defined below) and other outside investors own the issued and outstanding equity of Portfolio Holdings. ​ Merger Transaction The Company considered the following relevant facts for this determination: ● At the time of the Merger closing, Old SAFE shareholders, excluding the Old SAFE shares held directly by iStar, members of iStar management and Star Holdings, control a majority of the voting interests in the Company and the combined company operates under the name “Safehold Inc.;” ​ ● The composition of the combined company’s board of directors, which includes three directors from Old SAFE, two directors from iStar, and two management members of both Old SAFE and iStar; ​ ● Old SAFE was the larger entity by size when comparing the key metrics of total assets, total revenue and net income (loss) from continuing operations and allocable to common shareholders; and ​ ● Substantially all of the assets and liabilities of the Company consist of the historical assets and liabilities of Old SAFE, and the go-forward business plan of the Company is to conduct the Ground Lease business conducted by Old SAFE prior to the Merger. ​ As a result, the historical financial statements of Old SAFE become the historical financial statements of the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3—Summary of Significant Accounting Policies Significant Accounting Policies ​ Allowance for credit losses on net investment in sales-type leases and Ground Lease receivables ​ Interest receivable is not included in the Company’s allowance for credit losses on net investment in sales-type leases and Ground Lease receivables as the Company performs timely write-offs, if any, of aged interest receivables. The Company has also made a policy election to write off aged interest receivables through interest income from sales-type leases as opposed to through the provision for credit losses. ​ Fair Values both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The Company determines the estimated fair values of financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the Company and the Company’s own assumptions about market participant assumptions. The following table presents the carrying value and fair value for the Company’s financial instruments ($ in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2024 ​ As of December 31, 2023 ​ ​ Carrying ​ Fair ​ Carrying ​ Fair ​ Value Value Value Value Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net investment in sales-type leases (1) ​ $ 3,440 ​ $ 3,818 ​ $ 3,255 ​ $ 3,118 Ground Lease receivables (1) ​ 1,779 ​ 2,069 ​ 1,622 ​ 1,603 Loans receivable, net - related party (1) ​ ​ 112 ​ ​ 115 ​ ​ 112 ​ ​ 114 Cash and cash equivalents (2) ​ 16 ​ 16 ​ 19 ​ 19 Restricted cash (2) ​ 9 ​ 9 ​ 28 ​ 28 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt obligations, net (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ 1,035 ​ ​ 972 ​ ​ 739 ​ ​ 617 Level 3 ​ ​ 3,261 ​ ​ 2,796 ​ ​ 3,315 ​ ​ 2,874 Total debt obligations, net ​ ​ 4,296 ​ 3,768 ​ 4,054 ​ 3,491 (1) The fair value of the Company’s net investment in sales-type leases, Ground Lease receivables and loans receivable, net – related party are classified as Level 3 within the fair value hierarchy . The fair value of the Company’s debt obligations traded in secondary markets are classified as Level 1 within the fair value hierarchy and the fair value of the Company’s debt obligations not traded in secondary markets are classified as Level 3 within the fair value hierarchy. (2) The Company determined the carrying values of its cash and cash equivalents and restricted cash approximated their fair values and are classified as Level 1 within the fair value hierarchy . ​ Redeemable Noncontrolling Interests the investors in the February 2022 transaction had the right to cause their Caret units purchased in February 2022 to be redeemed by Portfolio Holdings at their original purchase price less the amount of distributions previously made on such units. less the amount of distributions previously made on such units The Company classified these redeemable Caret units in accordance with Accounting Standards Codification (“ASC”) 480: Distinguishing Liabilities from Equity. ASC 480-10-S99-3A requires that equity securities redeemable at the option of the holder be classified outside of permanent stockholders’ equity. The Company classified redeemable Caret units as “Redeemable noncontrolling interests” in its consolidated balance sheets and consolidated statements of changes in equity. The redeemable noncontrolling interest’s carrying amount was equal to the higher of (i) the initial carrying amount, increased or decreased for the redeemable noncontrolling interest’s share of net income or loss and dividends; or (ii) the redemption value. Acquisitions ​ The Company’s acquisition of iStar in 2023 was accounted for as a business combination. For business combinations, the Company recognizes and measures identifiable assets acquired, liabilities assumed and any noncontrolling interest in the acquiree at their fair values on the Company’s consolidated balance sheets. I ​ Fair values are based on available information including discounted cash flow analysis or similar fair value models. Fair value estimates are also made using significant assumptions such as capitalization rates, discount rates, fair market lease rates and other market data. The fair value of the Company’s interests in equity investments acquired is calculated using the fair value of the investments held by the venture, which are valued using methods as described above, and considers the Company’s economics in the venture. The fair value of financial instruments, which could include loans receivable or net investment in sales-type leases, is based on current market conditions and loan or lease agreements in place. The fair value of tangible assets, which could include land, buildings, building improvements and tenant improvements is determined as if these assets are vacant. Intangible assets may include the value of right of use lease assets, above-market leases and in-place leases. As lessee, right of use lease assets and lease liabilities are As lessee, operating lease right of use assets are included in “Deferred expenses and other assets, net” and operating lease liabilities are recorded in “Accounts payable, accrued expenses and other liabilities” on the Company’s consolidated balance sheets. As lessee, above-market operating lease intangibles and below-market lease assets are each recorded at their fair values and included in “Deferred expenses and other assets, net” on the Company’s consolidated balance sheets. ​ The table below shows the Company’s purchase consideration for the acquisition of iStar ($ in thousands): ​ ​ ​ ​ Total Company shares as purchase price (1) ​ ​ 1,195,034 Stock price of the Company’s common stock (2) ​ $ 29.78 Fair value of the Company's stock transferred ​ ​ 35,588 Cash consideration paid by the Company to iStar ​ ​ 88,685 Purchase consideration ​ $ 124,273 (1) The total post-Merger shares of the Company to be held by iStar shareholders includes 12.7 million shares that were issued as consideration for the investment in Old SAFE previously held by iStar as of March 30, 2023 that were retired in connection with the Merger. Accordingly, these shares are excluded from the purchase consideration as they are reflected as a treasury stock repurchase and retirement by Old SAFE. (2) Based on the closing price of Old SAFE’s common stock as of March 30, 2023, representing the final closing price prior to the effective time of the Merger. ​ The Merger was accounted for as a business combination pursuant to ASC 805 and all Merger related costs were expensed as incurred. The Company recorded $0.1 million of Merger expenses during the three months ended September 30, 2023 in “Other expense” in the Company’s consolidated statements of operations. The Company recorded $18.9 million of Merger expenses during the nine months ended September 30, 2023, of which $14.1 million was recorded in “Other expense” and $4.8 million was recorded in “General and administrative” in the Company’s consolidated statements of operations. During the nine months ended September 30, 2023, the Company also recorded $0.9 million of related non-recurring charges in “Other expense” and a provision for credit losses of $2.3 million on the Secured Term Loan Facility (refer to Note 6) which was originated at the time of the Merger in conjunction with the Spin-Off. Excluding $3.0 million of related non-recurring charges and the $2.3 million provision for credit losses on the Secured Term Loan Facility, the Company has incurred $26.6 million of Merger expenses. The following table sets forth the preliminary allocation as of March 31, 2023 of the purchase consideration to the fair values of identifiable tangible and intangible assets acquired and liabilities assumed, recognized as a result of the acquisition described in Note 1 above, measurement period adjustments and a final allocation of the purchase consideration ($ in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Preliminary ​ Measurement ​ Final ​ ​ Purchase Price ​ Period ​ Purchase Price Cash and cash equivalents ​ $ 3,213 ​ $ — ​ $ 3,213 Real estate ​ ​ 1,508 ​ ​ — ​ ​ 1,508 Equity investments (1) ​ ​ 61,247 ​ ​ — ​ ​ 61,247 Deferred tax asset (2) ​ ​ — ​ ​ 6,292 ​ ​ 6,292 Deferred expenses and other assets (2)(3) ​ ​ 25,442 ​ ​ 6,480 ​ ​ 31,922 Total assets acquired ​ ​ 91,410 ​ ​ 12,772 ​ ​ 104,182 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accounts payable, accrued expenses and other liabilities (2)(4) ​ ​ (22,939) ​ ​ (2,340) ​ ​ (25,279) Debt obligations (5) ​ ​ (99,995) ​ ​ — ​ ​ (99,995) Total liabilities assumed ​ ​ (122,934) ​ ​ (2,340) ​ ​ (125,274) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net identifiable (liabilities assumed) assets acquired ​ ​ (31,524) ​ ​ 10,432 ​ ​ (21,092) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Purchase consideration ​ $ 124,273 ​ $ — ​ $ 124,273 Add: net identifiable liabilities assumed ​ ​ 31,524 ​ ​ (10,432) ​ ​ 21,092 Goodwill (6) ​ ​ 155,797 ​ ​ (10,432) ​ ​ 145,365 (1) Equity investments were valued using discount rates between 7.2% and 13.9% and are classified as Level 3 within the fair value hierarchy. (2) During the three months ended June 30, 2023, the Company recorded a deferred tax asset in the amount of $6.3 million, net of a valuation allowance in the amount of $2.8 million, and reduced goodwill by $6.3 million. The net deferred tax asset relates to net operating loss carryovers to which the Company’s taxable REIT subsidiary is a successor and were finalized upon filing tax returns subsequent to the Merger for periods prior to the Merger. During the three months ended September 30, 2023, the Company recognized $6.5 million of deferred expenses and other assets related to final state tax receivables and $2.3 million in accounts payable, accrued expenses and other liabilities as a result of finalizing its tax returns which produced additional information not available at the time of the Merger. The following table presents a rollforward of the Company’s goodwill: ​ ​ ​ ​ Balance at December 31, 2022 ​ $ — Goodwill recognized at Merger ​ ​ 155,797 Reduction to goodwill resulting from measurement period adjustments ​ ​ (10,432) Impairment ​ ​ (145,365) Balance at December 31, 2023 ​ $ — (3) Deferred expenses and other assets includes $11.0 million attributable to operating lease right of use assets , $4.7 million attributable to prepaid expenses resulting from the settlement of iStar’s compensation plans, $2.1 million attributable to in-place prepaid contracts, $1.3 million attributable to office furniture and equipment and $6.3 million attributable to other receivables. (4) Accounts payable, accrued expenses and other liabilities primarily includes a $14.2 million operating lease liability . In addition, under the Merger Agreement, iStar was required to fund its share of merger-related costs and to provide sufficient cash to fund any unresolved corporate obligations and accrued liabilities or costs yet-to-be incurred prior to the Merger. Accounts payable, accrued expenses and other liabilities includes approximately $8.7 million of obligations assumed from iStar, which are offset with corresponding amounts in cash and cash equivalents and amounts receivable in deferred expenses and other assets, net sufficient to settle such obligations. (5) Debt obligations were valued using a discount rate of 6.7% and are classified as Level 3 within the fair value hierarchy. (6) Goodwill is calculated as the excess of purchase consideration over the fair value of the net identifiable assets acquired and primarily relates to the acquisition of iStar’s workforce and future synergies expected to be realized after the completion of the Merger. ​ During the three months ended September 30, 2023, the Company experienced a precipitous and sustained decline in the price per share of its common stock, which it identified as an indicator of goodwill impairment. As a result, the Company performed an interim goodwill evaluation. At that time, the Company determined that its current operations are carried out through a single reporting unit with a carrying value of approximately $2.4 billion. The estimated fair value of the Company was determined to be the Company’s market capitalization adjusted for a control premium estimated by the Company representing an amount a market participant would pay to obtain a controlling interest in the Company. The Company determined that its carrying value exceeded its estimated fair value and therefore recorded an impairment of goodwill. The Company recorded a $145.4 million full impairment of the goodwill recognized as a result of the Merger, which is recorded as a non-cash charge in “Impairment of goodwill” in the Company’s consolidated statements of operations. Goodwill did not have any tax impact on the Company’s financial statements. ​ The following table summarizes the Company's pro forma revenues and net income (loss) for the three and nine months ended September 30, 2023 as if the Merger described in Note 1 was completed on January 1, 2022 ($ in thousands): (1) ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, 2023 ​ September 30, 2023 Pro forma revenues ​ ​ $ 85,561 ​ $ 268,478 Pro forma net income (loss) ​ ​ (122,846) ​ ​ (66,412) (1) The pro forma revenues and net income (loss) are presented for informational purposes only and may not be indicative of what the actual results of operations of the Company would have been assuming the transaction occurred on January 1, 2022, nor do they purport to represent the Company’s results of operations for future periods. From the date of the Merger closing through September 30, 2023, $0.1 million of total revenues and $6.0 million of net income of the acquiree are included in the Company’s consolidated statements of operations. ​ New accounting pronouncements In August 2023, the FASB issued ASU 2023-05, Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement (“ASU 2023-05”). ASU 2023-05 requires a joint venture to initially measure all contributions received upon its formation at fair value and is effective for all joint venture entities with a formation date on or after January 1, 2025. ASU 2023-05 is to be applied on a prospective basis, while retrospective application can be elected for joint ventures formed before the effective date. The Company is currently evaluating ASU 2023-05 but does not expect this standard to have a material impact on its consolidated financial statements. ​ In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 improves disclosures for reportable segments primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating ASU 2023-07 but ​ In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires greater disaggregation of information in the rate reconciliation, income taxes paid disaggregated by jurisdiction and certain other amendments to improve income tax disclosures. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating ASU 2023-09 but does not expect this standard to have a material impact on its consolidated financial statements.

Leases [Abstract]
Net Investment in Sales-type Leases and Ground Lease Receivables	Note 4—Net Investment in Sales-type Leases and Ground Lease Receivables The Company classifies certain of its Ground Leases as sales-type leases and records the leases within “Net investment in sales-type leases” on the Company’s consolidated balance sheets and records interest income in “Interest income from sales-type leases” in the Company’s consolidated statements of operations. In addition, the Company may enter into transactions whereby it acquires land and enters into Ground Leases directly with the seller. These Ground Leases qualify as sales-type leases and, as such, do not qualify for sale leaseback accounting and are accounted for as financing receivables in accordance with ASC 310 - Receivables and are included in “Ground Lease receivables” on the Company’s consolidated balance sheets. The Company records interest income from Ground Lease receivables in “Interest income from sales-type leases” in the Company’s consolidated statements of operations. In May 2023, the Company entered into a joint venture with a sovereign wealth fund, which is also an existing shareholder, focused on new acquisitions for certain Ground Lease investments. The Company committed approximately $275 million for a 55% controlling interest in the joint venture and the sovereign wealth fund committed approximately $225 million for a 45% noncontrolling interest in the joint venture. Each party’s commitment is discretionary. The joint venture is a voting interest entity and the Company consolidates the joint venture in its financial statements due to its controlling interest. The Company’s joint venture partners’ interest was recorded in “Noncontrolling interests” on the Company’s consolidated balance sheet as of December 31, 2023.

The Company is obligated to pay the owner of the property $0.5 million, subject to adjustment for changes in the CPI, per year through 2044; however, the Company’s Ground Lease tenant at the property pays this expense directly under the terms of a master lease. Operating lease right-of-use asset is amortized on a straight-line basis over the term of the lease and is recorded in “Real estate expense” in the Company’s consolidated statements of operations. During both the three months ended September 30, 2024 and 2023, the Company recognized $0.1 million in “Real estate expense” and $0.1 million in “Other income” from its operating lease right-of-use asset.

The difference between the 5.15% stated rate and the cash interest rate will accrue in each semi-annual payment period and be paid in kind by adding such accrued interest to the outstanding principal balance, to be repaid at maturity in May 2052. The Company may, at its option, prepay at any time all, or from time to time any part of, the 5.15% Notes, in an amount not less than 5% of the aggregate principal amount of the 5.15% Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, and the applicable make-whole amount calculated in accordance with the indenture; provided, that, so long as no default or event of default shall then exist, at any time on or after February 13, 2052, the Company may, at its option, prepay all or any part of the 5.15% Notes at 100% of the principal amount so prepaid, together with, in each case, accrued interest to the prepayment date, without any make-whole amount. ​ In February 2024, Portfolio Holdings (as issuer) and the Company (as guarantor) issued $300.0 million aggregate principal amount of 6.10% senior notes due April 2034 (the “6.10% Notes”).

Commercial Paper Program Under the Commercial Paper Program, the Company may issue the Notes from time to time and will use the proceeds for general corporate purposes. The Commercial Paper Program is backed by the Company’s 2024 Unsecured Revolver. The Notes will be sold under customary terms in the commercial paper market and will rank pari passu with all of Portfolio Holding’s other unsecured senior indebtedness. The interest rates will vary based on the ratings assigned to the Notes by credit rating agencies and market conditions at the time of issuance. As of September 30, 2024, the Company had no outstanding balance under the Commercial Paper Program. Borrowings reduce amounts otherwise available under the 2024 Unsecured Revolver. The documents governing the Commercial Paper Program contain customary representations, warranties, covenants, defaults and indemnification provisions, and provide the terms under which the Notes will be sold pursuant to an exemption from the federal and state securities laws. Debt Covenants other things, these covenants may restrict the Company or certain of its subsidiaries’ ability to incur additional debt or liens, engage in certain mergers, consolidations and other fundamental changes, make other investments or pay dividends.

(2) The lease liability equals the present value of the minimum rental payments due under the lease discounted at the rate implicit in the lease or the Company’s incremental secured borrowing rate for similar collateral. For operating leases, lease liabilities were discounted at the Company’s weighted average incremental secured borrowing rate for similar collateral estimated to be 5.7% and the weighted average remaining lease term is 9.6 years. The Company assumed its operating leases from iStar in connection with the Merger and therefore did not directly make any payments under its operating leases for the three months ended March 31, 2023. During the three and six months ended September 30, 2023, the Company made payments of $1.4 million and $2.9 million, respectively, related to its operating leases. During the three and nine months ended September 30, 2024, the Company made payments of $1.4 million and $4.3 million, respectively, related to its operating leases. ​ Unfunded Commitments The Company also has unfunded forward commitments related to agreements that it entered into for the acquisition of new Ground Leases or additions to existing Ground Leases if certain conditions are met (refer to Note 14). These commitments may also include leasehold improvement allowances that will be funded to the Ground Lease tenants when certain conditions are met. As of September 30, 2024, the Company had an aggregate $150.3 million of such commitments. There can be no assurance that the conditions to closing for these transactions will be satisfied and that the Company will acquire the Ground Leases or fund the leasehold improvement allowances Other Commitments Through the Leasehold Loan Fund, the Company will generally fund construction and development loans and build-outs of space in real estate assets over a period of time if and when the borrowers and tenants meet established milestones and other performance criteria.

Risks and Uncertainties [Abstract]
Risk Management and Derivatives	Note 11—Risk Management and Derivatives In the normal course of its ongoing business operations, the Company encounters credit risk. Credit risk is the risk of default on the Company’s leases that result from a tenant’s inability or unwillingness to make contractually required payments. Risk concentrations Although the Company’s Ground Leases are geographically diverse and the tenants operate in a variety of industries and property types, to the extent the Company has a significant concentration of interest income from sales-type leases or operating lease income from any tenant, the inability of that tenant to make its payment could have a material adverse effect on the Company. The Company did not have a significant concentration of interest income from sales-type leases or operating lease income from any tenant for the periods presented. Derivative instruments and hedging activity The Company recognizes derivatives, if any, as either assets or liabilities on the Company’s consolidated balance sheets at fair value. Interest rate hedge assets are recorded in “Deferred expenses and other assets, net” and interest rate hedge liabilities are recorded in “Accounts payable, accrued expenses and other liabilities” on the Company’s consolidated balance sheets. If certain conditions are met, a derivative may be specifically designated as a hedge of the exposure to changes in the fair value of a recognized asset or liability, a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For the Company’s derivatives designated and qualifying as cash flow hedges, changes in the fair value of the derivatives are reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified into interest expense in the same periods during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s debt. If an interest rate hedge is terminated prior to maturity it could result in a net derivative instrument gain or loss that continues to be reported in accumulated other comprehensive (loss) and is reclassified into earnings over the period of the original forecasted hedged transaction. However, if it is probable that the original forecasted hedged transaction will not occur by the end of the original specified time period, the derivative instrument gain or loss reported in accumulated other comprehensive income (loss) will be reclassified into earnings immediately. If a derivative includes an other-than-insignificant financing element at inception, when the Company is deemed to be the lender all cash inflows and outflows of the derivative are considered cash flows from investing activities in the Company’s consolidated statements of cash flows and when the Company is deemed to be the borrower all cash inflows and outflows of the derivative are considered cash flows from financing activities in the Company’s consolidated statements of cash flows. ​ For the Company’s derivatives not designated as hedges, the changes in the fair value of the derivatives are reported in “Interest expense” in the Company’s consolidated statements of operations. Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements. ​ The table below presents the Company’s derivatives as well as their classification on the consolidated balance sheets as of September 30, 2024 and December 31, 2023 ($ in thousands): (1)(2)(3) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2024 December 31, 2023 ​ ​ ​ Fair ​ Fair ​ Balance Sheet Derivative Type Value ​ Value Location Assets ​ ​ Interest rate swaps ​ $ 27,692 ​ $ 34,864 Deferred expenses and other assets, net Total ​ $ 27,692 ​ $ 34,864 ​ ​ Liabilities ​ ​ Interest rate swaps ​ $ — ​ $ 2,546 Accounts payable, accrued expenses and other liabilities Total ​ $ — ​ $ 2,546 ​ ​ (1) As of September 30, 2024, the Company has two interest rate swap derivatives outstanding that mature in April 2028 and have an aggregate $500.0 million notional amount, which hedge in-place floating-rate debt. The Company also has three designated derivatives outstanding that protect the Company against interest rate volatility with respect to long-term debt to be placed in the future, which have an aggregate $350.0 million notional amount, one of which matures in December 2024 and two that mature in December 2025.

Equity [Abstract]
Equity	Note 12—Equity Common Stock In April 2023, the Company filed with the U.S. Securities and Exchange Commission (the “SEC”) an automatic shelf registration statement on Form S-3ASR. In addition, the Company and Portfolio Holdings entered into an ATM Equity Offering Sales Agreement (the “Primary Sales Agreement”) with the sales agents named therein pursuant to which the Company may sell, from time to time, shares of its common stock, $0.01 par value per share (“Common Stock”), having an aggregate gross sales price of up to $300.0 million (the “Primary Shares”) through or to the sales agents. The Company may sell the Primary Shares in amounts and at times to be determined by the Company from time to time but has no obligation to sell any of the Primary Shares. Actual sales, if any, will depend on a variety of factors to be determined by the Company from time to time, including, among other things, market conditions, the trading price of the Common Stock, capital needs and determinations by the Company of the appropriate sources of its funding. Through September 30, 2024, the Company has not sold any shares of its common stock through the Primary Sales Agreement. ​ In August 2023, the Company sold 6,500,000 shares of its common stock in an underwritten public offering for gross proceeds of $139.1 million. The Company’s Chief Executive Officer purchased $1.4 million in shares, or 65,420 shares, from the underwriters in the offering. The underwriters received the same underwriting discount with respect to these shares as they did from other shares of common stock sold to the public in the underwritten offering. Concurrently with the public offering, the Company sold $12.8 million in shares, or 599,983 shares, of its common stock to affiliates of MSD Partners in a private placement. The Company incurred a total of approximately $6.6 million of offering costs in connection with these transactions which were recorded as a reduction to additional paid-in capital. ​ Equity Plans iStar’s amended and restated 2009 Long-Term Incentive Program (the “LTIP”) was approved by stockholders in 2021 and remained in effect after the closing of the Merger. The LTIP is designed to provide incentive compensation for officers, key employees, directors and advisors of the Company. The LTIP provides for awards of stock options, shares of restricted stock, phantom shares, restricted stock units, dividend equivalent rights and other share-based performance awards. All awards under the LTIP are made at the discretion of the Company’s Board of Directors. consideration for their annual service as directors. On June 20, 2023, the LTIP was further amended to, among other things, increase the aggregate number of shares of common stock available for issuance. In May 2024, the Company issued an aggregate 32,300 shares of its common stock with a grant date fair value of $20.78 per share to its directors that vest after one year in consideration for their annual service as directors. In addition, in May 2024, the Company’s shareholders approved an increase to the LTIP of 1,000,000 shares. As of September 30, 2024, an aggregate of 1,054,098 shares of the Company’s common stock remains available for awards under the LTIP. As of September 30, 2024, there was $8.6 million of total unrecognized compensation cost related to all unvested restricted stock units that is expected to be recognized over a weighted average remaining vesting/service period of 1.8 years . Caret Performance Incentive Plan During the third quarter of 2018, Old SAFE adopted, and in the second quarter of 2019, its stockholders approved, the Caret Performance Incentive Plan (the “Original Caret Performance Incentive Plan”). Under the Original Caret Performance Incentive Plan, 1,500,000 Caret units were reserved for grants of performance-based awards to Original Caret Performance Incentive Plan participants, including certain of executives of iStar, and Old SAFE’s directors and service providers. Grants under the Original Caret Performance Incentive Plan were subject to vesting based on time-based service conditions and hurdles relating to Old SAFE’s common stock price, all of which have been satisfied. In connection with the Merger, certain of Old SAFE’s former executive officers, entered into re-vesting agreements pursuant to which the executives agreed to subject 25% of their previously vested Caret units to additional vesting conditions which will be satisfied on the second anniversary of the Merger, subject to the applicable executive’s continued employment through such date. In the event of a termination of the executive’s employment by the Company without “cause”, or due to the executive’s death, disability or retirement, the unvested Caret units shall continue to vest as and when the vesting conditions described above are satisfied. In connection with the consummation of the Merger and the Caret Restructuring, Old SAFE, Caret Ventures and CARET Management Holdings LLC assigned each Award Agreement (as defined in the Original Caret Performance Incentive Plan) relating to outstanding Caret unit awards to Portfolio Holdings pursuant to the Omnibus Assignment, Assumption and Amendment Agreement, dated as of March 31, 2023 (the “Caret Assignment Agreement”). Following the effectiveness of the Caret Assignment Agreement, Old SAFE amended and restated the Original Caret Performance Incentive Plan (the “Amended Caret Performance Incentive Plan”). Prior to the Merger, the Old SAFE compensation committee, and following the Merger, the Company’s compensation committee, approved the award of 76,801 new Caret units with an estimated grant date fair value of $8.1 million to executive officers and other employees, other than the Company’s Chief Executive Officer and the Company’s President and Chief Investment Officer, including 15,000 Caret units to the Company’s Chief Financial Officer. The new Caret unit awards were granted immediately following the Merger and the effectiveness of the Amended Caret Performance Incentive Plan, and cliff vest on the fourth anniversary of their grant date if the Company’s common stock has traded at an average per share price of $60.00 or more for at least 30 consecutive trading days during that four-year period. As of September 30, 2024, there was $3.5 million of total unrecognized compensation cost related to all unvested Caret units that is expected to be recognized over a remaining vesting/service period of 2.5 years. As of September 30, 2024, and after giving effect to the Caret Restructuring and the post-Merger Caret unit awards, Amended Caret Performance Incentive Plan participants held 1,371,254 Caret units, representing 14.4% of the then-outstanding Caret units and 11.4% of the then-authorized Caret units. During the three and nine months ended September 30, 2024, the Company recognized $0.3 million and $0.6 million, respectively, of expense from Caret units, which is recorded in “General and administrative” in the Company’s consolidated statements of operations and “Noncontrolling interests” on the Company’s consolidated balance sheets. During the three and nine months ended September 30, 2023, the Company recognized $0.5 million and $1.0 million, respectively, in expense from Caret units, which is recorded in “General and administrative” in the Company’s consolidated statements of operations and “Noncontrolling interests” on the Company’s consolidated balance sheets. 401(K) Plan ​ Accumulated Other Comprehensive Income (Loss) Noncontrolling Interests Redeemable Noncontrolling Interests” Dividends

Related Party Transactions [Abstract]
Related Party Transactions	Note 14—Related Party Transactions Prior to the Merger, the Company was externally managed by an affiliate of iStar. iStar was an active real estate investor for over 20 years and had an extensive network for sourcing investments, which included relationships with brokers, corporate tenants and developers that it has established over its long operating history. Management Agreement A summary of the terms of the management agreement with iStar prior to the Merger is below: ​ ​ ​ Manager SFTY Manager, LLC, a wholly-owned subsidiary of iStar Inc. Management Fee ​ Annual fee of 1.00% of total equity (up to $1.5 billion) Annual fee of 1.25% of total equity (for incremental equity of $1.5 billion to $3.0 billion) Annual fee of 1.375% of total equity (for incremental equity of $3.0 billion to $5.0 billion) and Annual fee of 1.5% of total equity (for incremental equity over $5.0 billion) Management Fee Consideration ​ At the discretion of the Company’s independent directors, payment will be made in cash or in shares of the Company’s common stock (valued at the greater of: (i) the volume weighted average market price during a specified pricing period; or (ii) the initial public offering price of $20.00 per share) Lock-up ​ Restriction from selling common stock received for management fees for two years from the date of such issuance (restriction will terminate in the event of and effective with the termination of the management agreement) Incentive Fee ​ None Term ​ Non-terminable through June 30, 2023, except for cause. Automatic annual renewals thereafter, subject to non-renewal upon certain findings by the Company’s independent directors and payment of termination fee. Termination Fee ​ 3x prior year’s management fee ​ The Company did not incur management fees to the Former Manager for the three months ended September 30, 2023. Expense Reimbursements The Company paid, or reimbursed iStar for, certain of the Company’s operating expenses as well as the costs of personnel performing certain legal, accounting, finance, due diligence tasks and other services, in each case except those specifically required to be borne or elected not to be charged by the iStar under the management agreement. The Company was not allocated any expenses from iStar for the three months ended September 30, 2023. During the nine months ended September 30, 2023, the Company was allocated $3.1 million in expenses from iStar. Acquisitions and Commitments Prior to the Merger, iStar participated in certain of the Company’s investment transactions, as the Company’s tenant or either as a seller of land or by providing financing to the Company’s Ground Lease tenants. Following is a list of transactions in which the Company and iStar or other persons deemed to be related parties have participated for the periods presented. These transactions were approved by the Company’s independent directors in accordance with the Company’s policy with respect to related party transactions. The Company entered into a discretionary commitment to fund up to $9.0 million of preferred equity in an entity that owns the leasehold interest under one of the Company’s office Ground Leases located in Washington, DC. This preferred equity position is intended to fund any operating cash flow deficits and leasing capital necessary at the property as our tenant explores potential re-leasing or a leasehold sale. In-place cash flows at the property covered ground rent through September 30, 2024, though a semi-annual property tax payment made in September 2024 produced a shortfall, which resulted in a $1.5 million funding. During the three and nine months ended September 30, 2024, the Company funded $1.5 million of the commitment which is included in “Deferred expenses and other assets” on the Company’s consolidated balance sheet as of September 30, 2024. In addition, the Company has recognized $1.7 million and $2.7 million, respectively, of interest income from sales-type leases from the Ground Lease in its consolidated statements of operations for the three and nine months ended September 30, 2024. In November 2021, the Company entered into an agreement pursuant to which it agreed to acquire land and a related Ground Lease originated by iStar when certain construction related conditions are met by a specified time period. The purchase price to be paid is $33.3 million, plus an amount necessary for iStar to achieve the greater of a 1.25x multiple or a 12% return on its investment. In December 2021, iStar contributed the Ground Lease to the Ground Lease Plus Fund (refer to Note 7). The Company has a noncontrolling interest in the Ground Lease Plus Fund and an affiliate of an existing shareholder (which is affiliated with one of the Company’s independent directors) has a noncontrolling interest in the Ground Lease Plus Fund. The terms of the Company’s commitment under the agreement did not change upon iStar’s contribution of the Ground Lease to the Ground Lease Plus Fund. In January 2024, the Company acquired the Ground Lease from the Ground Lease Plus Fund for $38.3 million. In addition, the Ground Lease documents contain future funding obligations to the Ground Lease tenant of approximately $51.8 million of leasehold improvement allowance upon achievement of certain milestones. In May 2023, certain milestones were met by the tenant as it exited the pre-development stage and the tenant began accessing the leasehold improvement allowance. As of September 30, 2024, the $51.8 million leasehold improvement allowance has been fully funded. In June 2021, the Company acquired from iStar a purchase option agreement for $1.2 million, which amount was equal to the deposit previously made by iStar under such option agreement plus assumption of iStar’s out of pocket costs and expenses in connection with entering into such option agreement. Under the option agreement, the Company had the right to acquire for $215.0 million a property that is under a separate option for the benefit of a third party, whereby such third party has the right to enter into a Ground Lease and develop approximately 1.1 million square feet of office space. In September 2023, the Company terminated its acquisition right under the option agreement for $0.3 million and recognized a loss of $1.9 million, inclusive of the derecognition of previously-capitalized deal structuring costs. The loss is recorded in “Other expense” in the Company’s consolidated statements of operations. In June 2021, the Company entered into two agreements pursuant to each of which it agreed to acquire land and a related Ground Lease originated by iStar when certain construction related conditions are met by a specified time period. The purchase price to be paid for each is $42.0 million, plus an amount necessary for iStar to achieve the greater of a 1.25x multiple and a 9% return on its investment. In addition, each Ground Lease provides for a leasehold improvement allowance up to a maximum of $83.0 million, which obligation would be assumed by the Company upon acquisition. In January 2022, iStar sold the Ground Leases to the Ground Lease Plus Fund in which the Company owns a noncontrolling interest and an existing shareholder (which is affiliated with one of the Company’s independent directors) owns a noncontrolling interest. One of the agreements expired in June 2024. There can be no assurance that the conditions to closing will be satisfied and that the Company will acquire the other property and Ground Lease from the Ground Lease Plus Fund. Caret units In February 2022, Old SAFE sold an aggregate of 108,571 Caret units, 1.08% of the then-authorized Caret units, to a group of investors (refer to Note 3). In addition, an affiliate of an existing shareholder (which is affiliated with one of the Company’s independent directors) made a commitment to purchase 28,571 Caret units, or 0.29% of the then-authorized Caret units, for a purchase price of $5.0 million. As part of the sale, Old SAFE agreed to use commercially reasonable efforts to provide public market liquidity for such Caret units by seeking to provide a listing of the Caret units (or securities into which they may be exchanged) on a public exchange within two years of the sale. Because public market liquidity was not achieved by February 2024, the investors in the February 2022 transaction had the right to cause their Caret units purchased in February 2022 to be redeemed by Portfolio Holdings at such purchase price less the amount of distributions previously made on such units. In April 2024, all of the investors in the February 2022 transaction exercised this right and elected to have their Caret units redeemed. On March 31, 2023, shortly before the closing of the Merger, iStar sold and affiliates of MSD Partners bought 5,405,406 shares of Old SAFE’s common stock then owned by iStar. On March 31, 2023, in conjunction with the closing of the Merger, affiliates of MSD Partners also purchased 100,000 Caret units (refer to Note 12) from the Company for an aggregate purchase price of $20.0 million. Additionally, on March 31, 2023, existing third-party Caret unit holders purchased an aggregate of 22,500 Caret units from the Company for an aggregate $4.5 million. ​ Star Holdings ​ On March 31, 2023, immediately prior to the closing of the Merger, the Company (then known as iStar Inc.) completed the Spin-Off, resulting in the spin-off of its remaining legacy assets and certain other assets pursuant to a separation and distribution agreement (the “Separation and Distribution Agreement”), dated as of March 31, 2023, by and between the Company and Star Holdings. The Separation and Distribution Agreement sets forth, among other things, Star Holdings’ agreements with the Company regarding the principal transactions necessary to separate Star Holdings from the Company. It also sets forth other agreements that govern certain aspects of Star Holdings’ relationship with the Company after the Spin-Off relating to the transfer of assets and assumption of liabilities, cash assets, release of claims, insurance, non-solicitation, segregation of accounts and other matters. The Separation and Distribution Agreement also includes a mutual release by Star Holdings, on the one hand, and the Company, on the other hand, of the other party from certain specified liabilities, as well as mutual indemnification covenants pursuant to which Star Holdings and the Company have agreed to indemnify each other from certain specified liabilities. ​ SpinCo Manager has entered into a management agreement with Star Holdings, pursuant to which it will operate and pursue the orderly monetization of Star Holding’s assets. Pursuant to the management agreement, Star Holdings paid to SpinCo Manager an annual management fee of $25.0 million for the term ended March 31, 2024. The annual fee declines to $15.0 million, $10.0 million and $5.0 million, respectively, in each of the following annual terms, and adjusts to 2.0% of the gross book value of Star Holding's assets, excluding shares of the Company’s common stock, thereafter. The management agreement had an initial one-year term and automatically renews for successive one-year terms each anniversary date thereafter unless previously terminated. The management agreement may be terminated by Star Holdings without cause by not less than one hundred eighty days’ written notice to SpinCo Manager upon the affirmative vote of at least two-thirds ​ In the event of a termination without cause by Star Holdings prior to the fourth anniversary of the Spin-Off, Star Holdings will pay SpinCo Manager a termination fee of $50.0 million minus the aggregate amount of management fees actually paid to SpinCo Manager prior to the termination date. However, if Star Holdings has completed the liquidation of its assets on or before the termination date, the termination fee will consist of any portion of the annual management fee that remained unpaid for the remainder of the then current annual term plus, if the termination date occurs on or before the third anniversary of the Spin-Off, the amount of the management fee that would have been payable for the next succeeding annual term, or if the termination date occurs after the third anniversary of the Spin-Off, zero. In the event of a termination by the Company based on a reduction in the amount of Star Holdings’ consolidated assets below designated thresholds, Star Holdings will pay SpinCo Manager a termination fee of $30.0 million if the termination occurs in the first year, $15.0 million if the termination occurs in the second year and $5.0 million if the termination occurs in the third year, in each case, plus the balance of any unpaid portion of the annual management fee for the applicable year. ​ During the three and nine months ended September 30, 2024, the Company recorded $3.7 million and $13.6 million, respectively, in management fees from Star Holdings. During the three and nine months ended September 30, 2023, the Company recorded $6.0 million and $13.2 million, respectively, in management fees from Star Holdings. The management fees are included in “Other income” in the Company’s consolidated statements of operations. ​ The Company and Star Holdings also entered into a governance agreement that places certain restrictions on the transfer and voting of the shares of the Company owned by Star Holdings, and a registration rights agreement under which the Company agreed to register such shares for resale in accordance with applicable securities laws. As of September 30, 2024, Star Holdings owned approximately 18.9% of the Company’s common stock outstanding through a wholly-owned subsidiary. ​ In April 2023, the Company, Portfolio Holdings and Star Investment Holdings SPV LLC (“Star Investment Holdings”), a subsidiary of Star Holdings, entered into an ATM Equity Offering Sales Agreement (the “Selling Stockholder Sales Agreement”) with the sales agents named therein pursuant to which Star Investment Holdings may sell, from time to time, subject to receiving the Company’s consent, up to 1,000,000 shares of the Company’s common stock (the “Selling Stockholder Shares”) through or to the sales agents. Star Investment Holdings may sell the Selling Stockholder Shares in amounts and at times to be determined by the Star Investment Holdings, subject to receiving the Company’s consent, from time to time but has no obligation to sell any of the Selling Stockholder Shares. Actual sales, if any, will depend on a variety of factors to be determined by Star Investment Holdings from time to time, including, among other things, market conditions, the trading price of the Company’s common stock, capital needs and determinations by Star Investment Holdings of the appropriate sources of its funding.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. In the opinion of management, the accompanying consolidated financial statements contain all adjustments consisting of normal recurring adjustments necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year.
Principles of Consolidation	Principles of Consolidation Consolidated VIEs The classifications of these assets are primarily within “Net investment in sales-type leases,” “Real estate, net,” “Real estate-related intangible assets, net” and “Deferred operating lease income receivable” on the Company’s consolidated balance sheets. The classifications of liabilities are primarily within “Debt obligations, net” and “Accounts payable, accrued expenses and other liabilities” on the Company’s consolidated balance sheets. The liabilities of these VIEs are non-recourse to the Company and can only be satisfied from each VIE’s respective assets. The Company has provided no financial support to VIEs that it was not previously contractually required to provide and did not have any unfunded commitments related to consolidated VIEs as of September 30, 2024.
Allowance for credit losses on net investment in sales-type leases and Ground Lease receivables	Allowance for credit losses on net investment in sales-type leases and Ground Lease receivables ​ Interest receivable is not included in the Company’s allowance for credit losses on net investment in sales-type leases and Ground Lease receivables as the Company performs timely write-offs, if any, of aged interest receivables. The Company has also made a policy election to write off aged interest receivables through interest income from sales-type leases as opposed to through the provision for credit losses.
Fair values	Fair Values both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The Company determines the estimated fair values of financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the Company and the Company’s own assumptions about market participant assumptions. The following table presents the carrying value and fair value for the Company’s financial instruments ($ in millions): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2024 ​ As of December 31, 2023 ​ ​ Carrying ​ Fair ​ Carrying ​ Fair ​ Value Value Value Value Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net investment in sales-type leases (1) ​ $ 3,440 ​ $ 3,818 ​ $ 3,255 ​ $ 3,118 Ground Lease receivables (1) ​ 1,779 ​ 2,069 ​ 1,622 ​ 1,603 Loans receivable, net - related party (1) ​ ​ 112 ​ ​ 115 ​ ​ 112 ​ ​ 114 Cash and cash equivalents (2) ​ 16 ​ 16 ​ 19 ​ 19 Restricted cash (2) ​ 9 ​ 9 ​ 28 ​ 28 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt obligations, net (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ 1,035 ​ ​ 972 ​ ​ 739 ​ ​ 617 Level 3 ​ ​ 3,261 ​ ​ 2,796 ​ ​ 3,315 ​ ​ 2,874 Total debt obligations, net ​ ​ 4,296 ​ 3,768 ​ 4,054 ​ 3,491 (1) The fair value of the Company’s net investment in sales-type leases, Ground Lease receivables and loans receivable, net – related party are classified as Level 3 within the fair value hierarchy . The fair value of the Company’s debt obligations traded in secondary markets are classified as Level 1 within the fair value hierarchy and the fair value of the Company’s debt obligations not traded in secondary markets are classified as Level 3 within the fair value hierarchy. (2) The Company determined the carrying values of its cash and cash equivalents and restricted cash approximated their fair values and are classified as Level 1 within the fair value hierarchy . ​
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests the investors in the February 2022 transaction had the right to cause their Caret units purchased in February 2022 to be redeemed by Portfolio Holdings at their original purchase price less the amount of distributions previously made on such units. less the amount of distributions previously made on such units The Company classified these redeemable Caret units in accordance with Accounting Standards Codification (“ASC”) 480: Distinguishing Liabilities from Equity. ASC 480-10-S99-3A requires that equity securities redeemable at the option of the holder be classified outside of permanent stockholders’ equity. The Company classified redeemable Caret units as “Redeemable noncontrolling interests” in its consolidated balance sheets and consolidated statements of changes in equity. The redeemable noncontrolling interest’s carrying amount was equal to the higher of (i) the initial carrying amount, increased or decreased for the redeemable noncontrolling interest’s share of net income or loss and dividends; or (ii) the redemption value.
Acquisitions	Acquisitions ​ The Company’s acquisition of iStar in 2023 was accounted for as a business combination. For business combinations, the Company recognizes and measures identifiable assets acquired, liabilities assumed and any noncontrolling interest in the acquiree at their fair values on the Company’s consolidated balance sheets. I ​ Fair values are based on available information including discounted cash flow analysis or similar fair value models. Fair value estimates are also made using significant assumptions such as capitalization rates, discount rates, fair market lease rates and other market data. The fair value of the Company’s interests in equity investments acquired is calculated using the fair value of the investments held by the venture, which are valued using methods as described above, and considers the Company’s economics in the venture.

The net deferred tax asset relates to net operating loss carryovers to which the Company’s taxable REIT subsidiary is a successor and were finalized upon filing tax returns subsequent to the Merger for periods prior to the Merger. During the three months ended September 30, 2023, the Company recognized $6.5 million of deferred expenses and other assets related to final state tax receivables and $2.3 million in accounts payable, accrued expenses and other liabilities as a result of finalizing its tax returns which produced additional information not available at the time of the Merger.

(4) Accounts payable, accrued expenses and other liabilities primarily includes a $14.2 million operating lease liability . In addition, under the Merger Agreement, iStar was required to fund its share of merger-related costs and to provide sufficient cash to fund any unresolved corporate obligations and accrued liabilities or costs yet-to-be incurred prior to the Merger. Accounts payable, accrued expenses and other liabilities includes approximately $8.7 million of obligations assumed from iStar, which are offset with corresponding amounts in cash and cash equivalents and amounts receivable in deferred expenses and other assets, net sufficient to settle such obligations. (5) Debt obligations were valued using a discount rate of 6.7% and are classified as Level 3 within the fair value hierarchy. (6) Goodwill is calculated as the excess of purchase consideration over the fair value of the net identifiable assets acquired and primarily relates to the acquisition of iStar’s workforce and future synergies expected to be realized after the completion of the Merger. ​ During the three months ended September 30, 2023, the Company experienced a precipitous and sustained decline in the price per share of its common stock, which it identified as an indicator of goodwill impairment. As a result, the Company performed an interim goodwill evaluation. At that time, the Company determined that its current operations are carried out through a single reporting unit with a carrying value of approximately $2.4 billion. The estimated fair value of the Company was determined to be the Company’s market capitalization adjusted for a control premium estimated by the Company representing an amount a market participant would pay to obtain a controlling interest in the Company. The Company determined that its carrying value exceeded its estimated fair value and therefore recorded an impairment of goodwill. The Company recorded a $145.4 million full impairment of the goodwill recognized as a result of the Merger, which is recorded as a non-cash charge in “Impairment of goodwill” in the Company’s consolidated statements of operations. Goodwill did not have any tax impact on the Company’s financial statements. ​ The following table summarizes the Company's pro forma revenues and net income (loss) for the three and nine months ended September 30, 2023 as if the Merger described in Note 1 was completed on January 1, 2022 ($ in thousands): (1) ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, 2023 ​ September 30, 2023 Pro forma revenues ​ ​ $ 85,561 ​ $ 268,478 Pro forma net income (loss) ​ ​ (122,846) ​ ​ (66,412) (1) The pro forma revenues and net income (loss) are presented for informational purposes only and may not be indicative of what the actual results of operations of the Company would have been assuming the transaction occurred on January 1, 2022, nor do they purport to represent the Company’s results of operations for future periods.

The Company also has three designated derivatives outstanding that protect the Company against interest rate volatility with respect to long-term debt to be placed in the future, which have an aggregate $350.0 million notional amount, one of which matures in December 2024 and two that mature in December 2025. These designated hedges protect the Company against interest rate volatility with respect to future debt with a tenor of approximately 30 years . (2) Over the next 12 months, the Company expects that $1.1 million related to cash flow hedges will be reclassified from “Accumulated other comprehensive income (loss)” as an increase to interest expense. (3) The fair value of the Company’s derivatives is estimated using valuation techniques utilized by a third-party specialist using observable inputs such as interest rates and contractual cash flow and are classified as Level 2 within the fair value hierarchy.
