Trading Arrangements, by Individual
Material Terms of Trading Arrangement	Item 5. Other Information Rule 10b5-1 Trading Plans On September 13, 2023, Martin E. Stein Jr ., the Company’s Executive Chairman of the Board of the Company, took the following actions: (i) Mr. Stein terminated a trading arrangement he had previously adopted with respect to the sale of the Company’s common stock (a “Rule 10b5-1 Trading Plan”). Mr. Stein’s Rule 10b5-1 Trading Plan was adopted on February 23, 2023 and, prior to its termination by Mr. Stein, was to expire by its terms on March 31, 2024 . This Rule 10b5-1 Trading Plan provided for the sale of up to 100,000 shares of common stock pursuant to multiple limit orders. As of the date of termination of this plan, Mr. Stein had not sold any shares of common stock under its terms. (ii) Mr. Stein adopted a new Rule 10b5-1 Trading Plan that is intended to satisfy the affirmative defense conditions of Securities Exchange Act Rule 10b5-1(c). Mr. Stein’s Rule 10b5-1 Trading Plan, which expires on February 15, 2025 , provides for the sale of up to 50,000 shares of common stock pursuant to multiple limit orders. Since adoption of this plan, Mr. Stein has not sold any shares of common stock under its terms. Entry into Material Definitive Agreements Indemnification Agreements On November 2, 2023, the Company entered into an indemnification agreement (an “Indemnification Agreement”) with each current member of its Board of Directors and each of its executive officers (each being referred to as an “Indemnified Party” and collectively as the “Indemnified Parties”). These Indemnification Agreements require the Company, among other things, to indemnify and hold harmless its directors and executive officers against claims, lawsuits, proceedings and liabilities (collectively, “Claims”) that may arise by reason of their status or capacity with, or service to, the Company and its subsidiaries, to the fullest extent permitted by the Company’s Articles of Incorporation, Bylaws and the Florida Business Corporation Act. These Indemnification Agreements also require the Company to advance expenses incurred by the Indemnified Parties in investigating or defending any such Claims, and sets forth various procedures in respect of such advancement and indemnification. The Indemnification Agreements also require the Company to procure customary directors and officers liability insurance, subject to certain conditions. The Company believes that these agreements are appropriate and necessary to attract and retain qualified individuals to serve as directors and executive officers. The foregoing summary of the terms of the Indemnification Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the “form of” Indemnification Agreement, a copy of which is filed as Exhibit 10.1 to this Quarterly Report on Form 10-Q, and is incorporated herein by reference.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	1. O rganization and Significant Accounting Policies General Regency Centers Corporation (the "Parent Company") began its operations as a REIT in 1993 and is the general partner of Regency Centers, L.P. (the "Operating Partnership"). The Parent Company primarily engages in the ownership, management, leasing, acquisition, development, and redevelopment of shopping centers through the Operating Partnership, and has no other assets other than through its investment in the Operating Partnership, and its only liabilities are $ 200 million of unsecured private placement notes, which are co-issued and guaranteed by the Operating Partnership. The Parent Company guarantees all of the unsecured debt of the Operating Partnership. As of September 30, 2023, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis ow ned 379 properties and held partial interests in an additional 102 properties through unconsolidated Investments in real estate partnerships (also referred to as "joint ventures" or "investment partnerships"). The information included in this Report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2022, as certain disclosures in this Report that would duplicate those included in such Annual Report on Form 10-K are not included in these consolidated financial statements. The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to fairly state the results for the interim periods presented. These adjustments are considered to be of a normal recurring nature. Acquisition of Urstadt Biddle Properties Inc. On May 17, 2023 , the Parent Company entered into an Agreement and Plan of Merger (the “merger agreement”) by and among the Parent Company, Hercules Merger Sub, LLC, a wholly owned subsidiary of the Parent Company (“Merger Sub”), Urstadt Biddle Properties Inc. (“UBP” or “Urstadt Biddle”), UB Maryland I, Inc., a wholly owned subsidiary of Urstadt Biddle (“UB Sub I”), and UB Maryland II, Inc., a wholly owned subsidiary of UB Sub I (“UB Sub II”), pursuant to which, (a) UB Sub II merged with and into Urstadt Biddle (the “first merger”), with Urstadt Biddle surviving the first merger as a wholly owned subsidiary of UB Sub I, and (b) following the first merger, UB Sub I merged with and into Merger Sub (the “second merger” and together with the first merger, the “mergers”), with Merger Sub being the surviving entity in the second merger. The combined company continues to trade under the ticker symbol “REG” on the National Association of Securities Dealers Automated Quotations (the “NASDAQ”). The closing of the mergers completed on August 18, 2023 and each share of Urstadt Biddle’s common stock, par value $ 0.01 per share (“Urstadt Biddle common stock”), class A common stock, par value $ 0.01 per share (“Urstadt Biddle Class A common stock” and, together with Urstadt Biddle common stock, the “Urstadt Biddle common shares”), 6.25 % Series H Cumulative Redeemable Preferred Stock and 5.875 % Series K Cumulative Redeemable Preferred Stock converted into one equivalent share in UB Sub I, with respect to each class, subject to limited exceptions set forth in the merger agreement. Immediately thereafter, on August 18, 2023, each share of UB Sub I’s common stock, par value $ 0.01 per share, and class A common stock, par value $ 0.01 per share, converted into 0.347 of a share of common stock, par value $ 0.01 per share, of common stock of the Parent Company, without interest and subject to certain adjustments, subject to limited exceptions set forth in the merger agreement, and each share of UB Sub I’s 6.25 % Series H Cumulative Redeemable Preferred Stock and 5.875 % Series K Cumulative Redeemable Preferred Stock converted into one share of newly issued Parent Company 6.25 % Series A Cumulative Redeemable Preferred Stock (“Parent Company Series A preferred stock”) and 5.875 % Series B Cumulative Redeemable Preferred Stock (“Parent Company Series B preferred stock”), respectively ( collectively referred to as the “Preferred Stock”) . Risks and Uncertainties The success of the Company's tenants in operating their businesses and their corresponding ability to pay rent continue to be influenced by current economic challenges, which impact their cost of doing business, including but not limited to the impact of inflation, the cost and availability of labor, increasing energy prices and interest rates, and access to credit. Additionally, macroeconomic and geopolitical risks, including the current wars in Ukraine, and involving Israel and Gaza, create challenges that may exacerbate current market conditions in the United States of America ("U.S.", "USA" or "United States"). The policies implemented by the U.S. government to address these issues, including raising interest rates, could result in adverse impacts on the U.S. economy, including a slowing of growth and potentially a recession, thereby impacting consumer spending, tenants' businesses, and/or decreasing future demand for space in shopping centers. The potential impact of current economic challenges on the Company's financial condition, results of operations, and cash flows is subject to change and continues to depend on the extent and duration of these risks and uncertainties. Consolidation The Company consolidates properties that are wholly-owned, and properties where it owns less than 100% but has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Parent Company The Parent Company has a single class of common stock outstanding and two series of preferred stock outstanding. Ownership of the Operating Partnership The Operating Partnership's capital includes the Common Units and the Preferred Units. As of September 30, 2023, the Parent Company owned approximately 99.4 % of the outstanding Common Units, with the remaining limited Common Units held by third parties ("Exchangeable operating partnership units" or "EOP units"). The Parent Company currently owns all of the Preferred Units. Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or common stock (i.e., registered shares of the Parent). The Parent Company has evaluated the conditions as specified under Accounting Standards Codification ("ASC") Topic 480, Distinguishing Liabilities from Equity, as it relates to EOP units outstanding and concluded that the Parent Company has the right to satisfy the redemption requirements of the units by delivering shares of unregistered common stock. Accordingly, the Parent Company classifies EOP units as permanent equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity and Comprehensive Income. The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities that most significantly impact the Operating Partnership’s economic performance. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company's only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages. Real Estate Partnerships As of September 30, 2023, Regency held partial ownership interests in 120 properties through partnerships, of which 18 are consolidated. Regency's partners include institutional investors and real estate developers and/or operators (the "Partners" or "Limited Partners"). Regency has a variable interest in these entities through its equity interests, with Regency being the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships into its financial statements for which it is the primary beneficiary and reports the limited partners' interests as noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be reached by general creditors of the Company. Similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) September 30, 2023 December 31, 2022 Assets Net real estate investments $ 256,750 107,725 Cash, cash equivalents and restricted cash 7,240 2,420 Liabilities Notes payable 33,733 4,188 Equity Limited partners' interests in consolidated partnerships 89,594 24,364 Revenues and Other Receivables Other property income includes parking fees and other incidental income from the properties and is generally recognized at the point in time that the performance obligation is met. Income within Management, transaction, and other fees on the Consolidated Statements of Operations is primarily from contracts with the Company's real estate partnerships. The primary components of these revenue streams, the timing of satisfying the performance obligations, and amounts are as follows: Three months ended September 30, Nine months ended September 30, (in thousands) Timing of satisfaction of performance obligations 2023 2022 2023 2022 Management, transaction, and other fees: Property management services Over time $ 3,591 3,224 $ 10,536 10,152 Asset management services Over time 1,623 1,680 4,900 5,105 Leasing services Point in time 889 729 2,703 2,895 Other fees Point in time 976 134 2,084 798 Total management, transaction, and other fees $ 7,079 5,767 $ 20,223 18,950 The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $ 15.9 million and $ 16.4 million , as of September 30, 2023 and December 31, 2022 , respectively. Recent Accounting Pronouncements The following table provides a brief description of recently adopted accounting pronouncements and impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted : ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related to activities that impact debt, leases, derivatives, and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The amendments in this update provide exceptions to the guidance in Topic 815 related to changes to the critical terms of a hedging relationship due to reference rate reform, which if criteria are met, provide such changes should not result in the dedesignation and redesignation of the hedging relationship. March 2020 through March 31, 2023 The Company has elected to apply the hedge accounting expedients and exceptions related to changes to the reference rate from LIBOR to SOFR in the Company's interest rate swaps, which it completed during the three months ended March 31, 2023. Application of these exceptions preserves the hedge designation of interest rate swaps and the related accounting and presentation consistent with past presentation. ASU 2021-08 , Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The amendments in this update require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination rather than at fair value on the acquisition date required by Topic 805. January 1, 2023 The adoption of this ASU did no t have a material impact on the Company’s financial position and/or results of operations.

Real Estate Investments UBP Acquisition General With respect to the acquisition of UBP discussed in Note 1 - Acquisition of Urstadt Biddle Properties Inc, the following table provides the components that make up the total purchase price for the UBP acquisition: (in thousands, except stock price) Purchase Price Shares of common stock issued for acquisition 13,568 Closing stock price on August 17, 2023 $ 61.03 Value of common stock issued for acquisition $ 828,025 Other adjustments ( 9,495 ) Total value of common stock issued $ 818,530 Debt repaid 39,266 Preferred stock issuance 225,000 Transaction costs 57,197 Other cash payments 68 Total purchase price $ 1,140,061 Purchase Price Allocation The acquisition has been accounted for using the asset acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that the total cost or total consideration exchanged be allocated to the real estate properties and related lease intangibles on a relative fair value basis. All the other assets acquired, and liabilities assumed, including notes payable, are recorded at fair value. The total purchase price, including direct transaction costs capitalized, was allocated as follows: (in thousands) Purchase Price Allocation Real estate assets $ 1,379,835 Investments in unconsolidated real estate partnerships 35,942 Real estate assets 1,415,777 Cash, accounts receivable and other assets 51,902 Lease intangible assets 128,663 Total assets acquired 1,596,342 Notes payable 284,706 Accounts payable, accrued expenses, and other liabilities 37,500 Lease intangible liabilities 69,583 Total liabilities assumed 391,789 Non-controlling interest 64,492 Total purchase price $ 1,140,061 The acquired assets and assumed liabilities for an acquired operating property generally include, but are not limited to: land, buildings and improvements, identified tangible and intangible assets and liabilities associated with in-place leases, including tenant improvements, leasing costs, value of above-market and below-market leases, and value of acquired in-place leases. This methodology includes estimating an “as-if vacant” fair value of the physical property, which includes land, building, and improvements and also determines the estimated fair value of identifiable intangible assets and liabilities, considering the following categories: (i) value of in-place leases, and (ii) above and below-market value of in-place leases. The fair market value of the acquired operating properties is based on a valuation prepared by Regency with assistance of a third party valuation specialist. The third-party specialist utilized stabilized NOI and market specific capitalization rates as the primary valuation inputs in determining the fair value of the real estate assets. Management reviews the inputs used by the third-party specialist as well as the allocation of the purchase price to ensure reasonableness and that the procedures are performed in accordance with management's policy. Management and the third-party valuation specialist prepared their fair value estimates for each of the operating properties acquired. The allocation of the purchase price described above requires a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date. The following table details the weighted average amortization and net accretion periods, in years, of the major classes of intangible assets and intangible liabilities arising from the UBP acquisition: (in years) Weighted Average Amortization Period Assets: In-place leases 8.0 Above-market leases 7.0 Liabilities: Below-market leases 18.5 Other Acquisitions The following tables detail the other properties acquired for the periods set forth below: (in thousands) Nine months ended September 30, 2023 Date Purchased Property Name City/State Property Regency Ownership Purchase (1) Debt (1) Intangible (1) Intangible (1) Consolidated 5/1/2023 Sienna Phase 1 Houston, TX Development 75 % $ 2,695 — — — 5/18/2023 SunVet Holbrook, NY Development 99 % 24,140 — — — Total consolidated $ 26,835 — — — Unconsolidated 9/19/2023 Old Town Square Chicago, IL Operating 20 % 27,510 — 3,625 503 Total unconsolidated $ 27,510 — 3,625 503 Total property acquisitions $ 54,345 — 3,625 503 (in thousands) Nine months ended September 30, 2022 Date Purchased Property Name City/State Property Regency Ownership Purchase (1) Debt (1) Intangible (1) Intangible (1) Consolidated 3/1/2022 Glenwood Green Old Bridge, NJ Development 70 % $ 11,000 — — — 3/31/2022 Island Village Bainbridge Island, WA Operating 100 % 30,650 — 2,900 6,839 4/1/2022 Apple Valley (2) Apple Valley, MN Operating 100 % 34,070 — 4,773 490 4/1/2022 Cedar Commons (2) Minneapolis, MN Operating 100 % 29,330 — 4,369 58 4/1/2022 Corral Hollow (2) Tracy, CA Operating 100 % 40,600 — 3,410 74 4/1/2022 Shops at the Columbia (2) Washington, DC Operating 100 % 14,000 — 889 181 5/6/2022 Baederwood Shoppes Jenkintown, PA Operating 80 % 51,603 22,779 5,796 1,062 Total consolidated $ 211,253 22,779 22,137 8,704 Unconsolidated 3/25/2022 Naperville Plaza Naperville, IL Operating 20 % 52,380 22,074 4,336 814 6/24/2022 Baybrook East 1B Houston, TX Development 50 % 5,540 — — — Total unconsolidated $ 57,920 22,074 4,336 814 Total property acquisitions $ 269,173 44,853 26,473 9,518 (1) Amounts for purchase price and allocation are reflected at 100 %.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	6. Derivative Financial Instruments The Company may use derivative financial instruments, including interest rate swaps, caps, options, floors, and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with its borrowings. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company's operating and financial structure as well as to hedge specific anticipated transactions. The Company does not intend to utilize derivatives for speculative transactions or purposes other than mitigation of interest rate risk. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, the Company only enters into derivative financial instruments with counterparties with quality credit ratings. The Company does not anticipate that any of the counterparties will fail to meet their obligations. The Company's objectives in using interest rate derivatives are to attempt to stabilize interest expense where possible and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Leases [Abstract]
Leases	7. Leases Substantially all of the Company's leases are classified as operating leases. The Company's Lease income is comprised of both fixed and variable income. Fixed and in-substance fixed lease income includes stated amounts per the lease contract, which are primarily related to base rent, and in some cases stated amounts for common area maintenance ("CAM"), real estate taxes, and insurance (collectively, "Recoverable Costs"). Income for these amounts is recognized on a straight-line basis. Variable lease income includes the following two main items in the lease contracts: • Recoveries from tenants represents the tenants' contractual obligations to reimburse the Company for their portion of Recoverable Costs incurred. Generally, the Company's leases provide for the tenants to reimburse the Company based on the tenants' share of the actual costs incurred in proportion to the tenants' share of leased space in the property. • Percentage rent represents amounts billable to tenants based on the tenants' actual sales volume in excess of levels specified in the lease contract. The following table provides a disaggregation of lease income recognized as either fixed or variable lease income based on the criteria specified in ASC Topic 842: (in thousands) Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 Operating lease income Fixed and in-substance fixed lease income $ 235,489 215,077 $ 675,320 634,416 Variable lease income 77,901 70,473 233,019 210,390 Other lease related income, net: Above/below market rent and tenant rent inducement amortization, net 8,118 5,484 22,734 16,786 Uncollectible straight-line rent (1) 49 3,612 2,149 8,517 Uncollectible amounts billable in lease income ( 636 ) 1,110 958 12,156 Total lease income $ 320,921 295,756 $ 934,180 882,265 (1) The amounts include straight-line rent adjustments associated with converting cash basis to accrual basis accounting for certain leases.

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. Fair Value Measurements (a) Disclosure of Fair Value of Financial Instruments All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management's estimation, reasonably approximate their fair values, except for the following: September 30, 2023 December 31, 2022 (in thousands) Carrying Fair Value Carrying Fair Value Financial liabilities: Notes payable, net $ 3,992,093 3,588,977 3,726,754 3,333,378 Unsecured credit facilities $ 77,000 77,000 — — The above fair values represent management's estimate of the amounts that would be received from selling those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants as of September 30, 2023, and December 31, 2022, respectively. These fair value measurements maximize the use of observable inputs which are classified within Level 2 of the fair value hierarchy. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company's own judgments about the assumptions that market participants would use in pricing the asset or liability. The Company develops its judgments based on the best information available at the measurement date, including expected cash flows, appropriate risk-adjusted discount rates, and available observable and unobservable inputs. Service providers involved in fair value measurements are evaluated for competency and qualifications on an ongoing basis. As considerable judgment is often necessary to estimate the fair value of these financial instruments, the fair values presented above are not necessarily indicative of amounts that will be realized upon disposition of the financial instruments. (b) Fair Value Measurements The following financial instruments are measured at fair value on a recurring basis: Securities The Company has investments in marketable securities that are included within Other assets on the accompanying Consolidated Balance Sheets. The fair value of the securities was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of securities are recorded within Net investment loss (income) in the accompanying Consolidated Statements of Operations, and include unrealized losses of $ 1.0 million during the three months ended September 30, 2023 and 2022, and unrealized gains of $ 2.4 million and unrealized losses of $ 9.5 million during the nine months ended September 30, 2023 and 2022, respectively. Available-for-Sale Debt Securities Available-for-sale debt securities consist of investments in certificates of deposit and corporate bonds, and are recorded at fair value using either recent trade prices for the identical debt instrument or comparable instruments by issuers of similar industry sector, issuer rating, and size, to estimate fair value, which are considered Level 2 inputs of the fair value hierarchy. Unrealized gains or losses on these debt securities are recognized through Other comprehensive income. Interest Rate Derivatives The fair value of the Company's interest rate derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy. The following tables present the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis: Fair Value Measurements as of September 30, 2023 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 33,881 33,881 — — Available-for-sale debt securities 14,423 — 14,423 — Interest rate derivatives 21,328 — 21,328 — Total $ 69,632 33,881 35,751 — Fair Value Measurements as of December 31, 2022 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 40,089 40,089 — — Available-for-sale debt securities 14,492 — 14,492 — Interest rate derivatives 6,575 — 6,575 — Total $ 61,156 40,089 21,067 —

Stock Repurchase Program The Board has authorized a common stock repurchase program under which the Company may purchase, from time to time, up to a maximum of $ 250 million of its outstanding common stock through open market purchases, and/or in privately negotiated transactions (referred to as the "Repurchase Program"). The timing and price of stock repurchases, if any will be dependent upon market conditions and other factors. The stock repurchased, if not retired, would be treated as treasury stock. The Board's authorization for this repurchase program will expire on February 7, 2025 , unless modified, extended or earlier terminated by the Board. During the nine months ended September 30, 2023 , the Company executed multiple trades to repurchase 349,519 common shares under the Repurchase Program for a total of $ 20.0 million at a weighted average price of $ 57.22 per share.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	12. Commitments and Contingencies Litigation The Company is a party to litigation and is subject to other disputes, in each case that arise in the ordinary course of business. While the outcome of any particular lawsuit or dispute cannot be predicted with certainty, in the opinion of management, the Company's currently pending litigation and disputes are not expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. Legal fees are expensed as incurred. On May 17, 2023, the Company announced its entry into an agreement to acquire UBP and shortly thereafter filed a registration statement (the “Registration Statement”) with the SEC containing a proxy statement/prospectus in connection with obtaining approval of the proposed acquisition by UBP stockholders. As previously disclosed in the Company's Form 10-Q for the second quarter of 2023, a complaint was filed in Connecticut state court in connection with the proposed acquisition by a purported UBP stockholder, which alleged that, in connection with the proposed acquisition, the UBP board of directors breached its fiduciary duties under applicable law and that the Registration Statement failed to disclose allegedly material information. The Complaint also alleged that Regency aided and abetted the alleged breaches of fiduciary duty, and that all defendants engaged in negligent misrepresentation and concealment in connection with the Registration Statement. The complaint sought various remedies, including, among other things, injunctive relief, damages and attorneys’ fees. In addition to the Complaint, certain other purported stockholders of UBP sent demand letters (the “Demands,” and together with the Complaint, the “Matters”) alleging deficiencies and/or omissions regarding the disclosures made in the Registration Statement. The Matters were resolved during the quarter to avoid additional litigation and associated costs. The resolution involved the claimants’ acknowledgment that their claims were mooted by additional information disclosed in a Form 8-K filed by UBP with the SEC on August 8, 2023. In exchange for appropriate releases and the dismissal of the Complaint, we also made payments to the claimants and their attorneys, in the aggregate, totaling an immaterial amount. Environmental The Company is subject to numerous environmental laws and regulations. With respect to impact on the Company, these pertain primarily to chemicals historically used by certain current and former dry cleaning tenants, the existence of asbestos in older shopping centers, older underground petroleum storage tanks and other historic land uses. The Company believes that the ultimate disposition of currently known environmental matters will not have a material effect on its financial position, liquidity, or operations. The Company can give no assurance that existing environmental studies with respect to its shopping centers have revealed all potential environmental contaminants; that its estimate of liabilities will not change as more information becomes available; that any previous owner, occupant or tenant did not create any material environmental condition not known to the Company; that the current environmental condition of the shopping centers will not be affected by tenants and occupants, by the condition of nearby properties, or by unrelated third parties; and that changes in applicable environmental laws and regulations or their interpretation will not result in additional environmental liability to the Company. Letters of Credit The Company has the right to issue letters of credit under the Line up to an aggregate amount not to exceed $ 50.0 million, which reduces the credit availability under the Line. These letters of credit are primarily issued as collateral on behalf of its captive insurance subsidiary and to facilitate the construction of development projects. The Comp any had $ 9.1 million and $ 9.4 million in letters of credit outstanding as of September 30, 2023 and December 31, 2022 , respectively.

Acquisition of Urstadt Biddle Properties Inc.	Acquisition of Urstadt Biddle Properties Inc. On May 17, 2023 , the Parent Company entered into an Agreement and Plan of Merger (the “merger agreement”) by and among the Parent Company, Hercules Merger Sub, LLC, a wholly owned subsidiary of the Parent Company (“Merger Sub”), Urstadt Biddle Properties Inc. (“UBP” or “Urstadt Biddle”), UB Maryland I, Inc., a wholly owned subsidiary of Urstadt Biddle (“UB Sub I”), and UB Maryland II, Inc., a wholly owned subsidiary of UB Sub I (“UB Sub II”), pursuant to which, (a) UB Sub II merged with and into Urstadt Biddle (the “first merger”), with Urstadt Biddle surviving the first merger as a wholly owned subsidiary of UB Sub I, and (b) following the first merger, UB Sub I merged with and into Merger Sub (the “second merger” and together with the first merger, the “mergers”), with Merger Sub being the surviving entity in the second merger. The combined company continues to trade under the ticker symbol “REG” on the National Association of Securities Dealers Automated Quotations (the “NASDAQ”). The closing of the mergers completed on August 18, 2023 and each share of Urstadt Biddle’s common stock, par value $ 0.01 per share (“Urstadt Biddle common stock”), class A common stock, par value $ 0.01 per share (“Urstadt Biddle Class A common stock” and, together with Urstadt Biddle common stock, the “Urstadt Biddle common shares”), 6.25 % Series H Cumulative Redeemable Preferred Stock and 5.875 % Series K Cumulative Redeemable Preferred Stock converted into one equivalent share in UB Sub I, with respect to each class, subject to limited exceptions set forth in the merger agreement.

Risks and Uncertainties	Risks and Uncertainties The success of the Company's tenants in operating their businesses and their corresponding ability to pay rent continue to be influenced by current economic challenges, which impact their cost of doing business, including but not limited to the impact of inflation, the cost and availability of labor, increasing energy prices and interest rates, and access to credit. Additionally, macroeconomic and geopolitical risks, including the current wars in Ukraine, and involving Israel and Gaza, create challenges that may exacerbate current market conditions in the United States of America ("U.S.", "USA" or "United States"). The policies implemented by the U.S. government to address these issues, including raising interest rates, could result in adverse impacts on the U.S. economy, including a slowing of growth and potentially a recession, thereby impacting consumer spending, tenants' businesses, and/or decreasing future demand for space in shopping centers. The potential impact of current economic challenges on the Company's financial condition, results of operations, and cash flows is subject to change and continues to depend on the extent and duration of these risks and uncertainties.
Consolidation	Consolidation The Company consolidates properties that are wholly-owned, and properties where it owns less than 100% but has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Parent Company The Parent Company has a single class of common stock outstanding and two series of preferred stock outstanding. Ownership of the Operating Partnership The Operating Partnership's capital includes the Common Units and the Preferred Units. As of September 30, 2023, the Parent Company owned approximately 99.4 % of the outstanding Common Units, with the remaining limited Common Units held by third parties ("Exchangeable operating partnership units" or "EOP units"). The Parent Company currently owns all of the Preferred Units. Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or common stock (i.e., registered shares of the Parent). The Parent Company has evaluated the conditions as specified under Accounting Standards Codification ("ASC") Topic 480, Distinguishing Liabilities from Equity, as it relates to EOP units outstanding and concluded that the Parent Company has the right to satisfy the redemption requirements of the units by delivering shares of unregistered common stock. Accordingly, the Parent Company classifies EOP units as permanent equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity and Comprehensive Income. The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities that most significantly impact the Operating Partnership’s economic performance. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company's only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages.
Real Estate Partnerships	Real Estate Partnerships As of September 30, 2023, Regency held partial ownership interests in 120 properties through partnerships, of which 18 are consolidated. Regency's partners include institutional investors and real estate developers and/or operators (the "Partners" or "Limited Partners"). Regency has a variable interest in these entities through its equity interests, with Regency being the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships into its financial statements for which it is the primary beneficiary and reports the limited partners' interests as noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be reached by general creditors of the Company. Similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) September 30, 2023 December 31, 2022 Assets Net real estate investments $ 256,750 107,725 Cash, cash equivalents and restricted cash 7,240 2,420 Liabilities Notes payable 33,733 4,188 Equity Limited partners' interests in consolidated partnerships 89,594 24,364
Revenues and Other Receivables	Revenues and Other Receivables Other property income includes parking fees and other incidental income from the properties and is generally recognized at the point in time that the performance obligation is met. Income within Management, transaction, and other fees on the Consolidated Statements of Operations is primarily from contracts with the Company's real estate partnerships.

Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of recently adopted accounting pronouncements and impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted : ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related to activities that impact debt, leases, derivatives, and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The amendments in this update provide exceptions to the guidance in Topic 815 related to changes to the critical terms of a hedging relationship due to reference rate reform, which if criteria are met, provide such changes should not result in the dedesignation and redesignation of the hedging relationship. March 2020 through March 31, 2023 The Company has elected to apply the hedge accounting expedients and exceptions related to changes to the reference rate from LIBOR to SOFR in the Company's interest rate swaps, which it completed during the three months ended March 31, 2023. Application of these exceptions preserves the hedge designation of interest rate swaps and the related accounting and presentation consistent with past presentation. ASU 2021-08 , Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The amendments in this update require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination rather than at fair value on the acquisition date required by Topic 805. January 1, 2023 The adoption of this ASU did no t have a material impact on the Company’s financial position and/or results of operations.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles	The following table provides a brief description of recently adopted accounting pronouncements and impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted : ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related to activities that impact debt, leases, derivatives, and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The amendments in this update provide exceptions to the guidance in Topic 815 related to changes to the critical terms of a hedging relationship due to reference rate reform, which if criteria are met, provide such changes should not result in the dedesignation and redesignation of the hedging relationship. March 2020 through March 31, 2023 The Company has elected to apply the hedge accounting expedients and exceptions related to changes to the reference rate from LIBOR to SOFR in the Company's interest rate swaps, which it completed during the three months ended March 31, 2023. Application of these exceptions preserves the hedge designation of interest rate swaps and the related accounting and presentation consistent with past presentation. ASU 2021-08 , Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The amendments in this update require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination rather than at fair value on the acquisition date required by Topic 805. January 1, 2023 The adoption of this ASU did no t have a material impact on the Company’s financial position and/or results of operations.
