This Amendment No. 13 on Schedule 13D (the “Schedule 13D”) relating to shares of common stock, $0.01 par value per share (the “Shares”), of Safety, Income & Growth Inc., a Maryland corporation (the “Issuer”), is being filed by iStar Inc., a Maryland corporation (“iStar”), and supplements and amends the statement on Schedule 13D originally filed with the Commission on June 27, 2017 (as amended, the “Statement”).

Item 3.                                                         Source and Amount of Funds or Other Consideration.

The aggregate amount of funds used by iStar to acquire the Shares reported in Item 5(c) was $3,562,086.55.  The aggregate amount of funds used by iStar to acquire the Investor Units reported in Item 6 is $250.0 million.  iStar used its working capital to make such purchases.

Item 4.                                                         Purpose of Transaction.

iStar purchased additional Shares, as reported in Item 5(c) of this Statement, and the Investor Units reported in Item 6 of this Statement in order to increase its equity interest in the Issuer. See also Item 6.

Item 5.                                                         Interest in Securities of the Issuer.

(a)                                 As of December 31, 2018, iStar owns 7,647,317 Shares directly, or approximately 41.8% of the outstanding Shares.

As discussed in Item 6, on January 2, 2019, iStar purchased 12,500,000 newly issued limited partnership units designated as “Investor Units” of Safety Income and Growth Operating Partnership L.P. a subsidiary of the Issuer.  The Issuer has agreed to seek stockholder approval to exchange the Investor Units for Shares on a one-for-one basis.  On a pro forma basis, giving effect to the issuance of 12,500,000 Shares to iStar in such exchange, iStar will own 20,147,317 Shares representing 65.5% of the outstanding Shares.

(c)                                  Since filing Amendment No. 12 to the initial Statement, iStar purchased 210,042 Shares through open-market purchases conducted under a “written plan for trading securities” within the meaning of Rule 10b5-1 promulgated under the Securities and Exchange Act of 1934, as amended. Further details regarding these purchases are set forth below.

Item 6.                                                         Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

On January 2, 2019, iStar entered into an Investor Unit Purchase Agreement (the “Purchase Agreement”) with the Issuer and Safety Income and Growth Operating Partnership LP (“SAFE OP,” and together with the Issuer and its other subsidiaries, “SAFE”), pursuant to which iStar purchased from SAFE OP 12,500,000 newly designated limited partnership units (the “Investor Units”) at a purchase price of $20.00 per unit, for a total purchase price of $250.0 million.

SAFE intends to use the proceeds from the sale of the Investor Units to fund future investments in ground leases.  The Investor Units were issued in a transaction exempt from registration under the Securities Act of 1933, as amended.

Investor Units

The Investor Units are a newly-designated series of limited partnership interests in SAFE OP.  Each Investor Unit will receive distributions equivalent to distributions declared and paid on one Share.  The Investor Units have no voting rights.  They have limited protective consent rights over certain matters such as amendments to the terms of the Investor Units that would adversely affect the Investor Units.

The Investor Units may not be converted or exchanged for cash or other property; provided, however, that the Issuer has agreed to seek stockholder approval to exchange the Investor Units for Shares, on a one-for-one basis.  The Investor Units may not be transferred prior to such exchange.  They will be transferable if stockholder approval for the

5

exchange has not been obtained by June 30, 2019.  Prior to the stockholder meeting held to obtain approval for the exchange, SAFE will be restricted from issuing Shares or partnership units of SAFE OP at less than $20.00 per Share or unit other than grants pursuant to SAFE’s incentive plan; provided, however, that the Issuer may issue up to $100.0 million of Shares at a price less than $20.00 in an offering in which iStar is offered the opportunity to purchase shares to maintain its percentage ownership interest in SAFE.

The Investor Units represent an approximately 40.6% fully diluted economic interest in SAFE.  After giving effect to the issuance of the Investor Units, iStar’s aggregate fully diluted economic interest in SAFE (including the Shares and Investor Units owned by iStar) is approximately 65.5%; however, iStar’s voting power in SAFE remains approximately 41.9% both before and after giving effect to the purchase of the Investor Units, and will remain 41.9% after giving effect to the exchange of Investor Units for Shares, as a result of limitations on iStar’s voting power contained in the Stockholder’s Agreement described below.

Stockholder’s Agreement

In connection with iStar’s purchase of the Investor Units, iStar and the Issuer entered into a Stockholder’s Agreement on January 2, 2019, which sets forth certain rights and obligations of iStar and SAFE, respectively, relating to iStar’s ownership of the Investor Units and Shares.

The Stockholder’s Agreement provides that with respect to any matter presented for a vote or written consent of the holders of Shares after the date on which the Investor Units are exchanged for Shares (the “Exchange Date”), iStar will vote all “Excess Shares” in the same proportions as the votes cast or consents delivered by holders of Shares other than iStar.  “Excess Shares” means the number of Shares, including, without limitation, Shares issued in exchange for Investor Units (“Exchange Shares”) owned by iStar from time to time that exceed 41.9% of the outstanding Shares at such time, including the Exchange Shares.  These voting limitations will remain in effect until the first date on which iStar’s aggregate ownership of Shares is less than 41.9% of the outstanding Shares.

The Stockholder’s Agreement also provides that, notwithstanding the voting limitations described above, for three years, iStar will cast all of its voting power in favor of three individuals who are independent of each of iStar and SAFE within the meaning of the listing rules of the New York Stock Exchange to serve as directors of SAFE REIT.  iStar has also agreed to certain standstill provisions for a term of two years.

The Stockholder’s Agreement restricts iStar’s ability to transfer Exchange Shares for one year after the Exchange Date.  In addition, for a period of two years, iStar will not transfer Shares representing more than 20% of the outstanding Shares in one transaction or a series of related transactions to any person or group, other than transfers of Shares pursuant to a widely distributed public offering, unless the non-iStar holders of Shares are afforded the opportunity to participate in the transaction at the same price per security and in the same proportion as their Shares represents of the outstanding fully diluted equity of SAFE.

The Stockholder’s Agreement provides that iStar will have certain rights (but not the obligation) to maintain its percentage ownership interest of Shares by purchasing additional Shares when SAFE issues additional Shares from time to time, subject to certain exceptions.  Any Shares purchased by iStar pursuant to such rights will be subject to the voting power limitations set forth in the agreement.

Additional Agreements

In connection with iStar’s purchase of the Investor Units, SFTY Manager LLC (a wholly-owned subsidiary of iStar), iStar, the Issuer and SAFE OP entered into an Amendment and Restated Management Agreement, dated January 2, 2019.

In connection with iStar’s purchase of the Investor Units, iStar and the Issuer also entered into an Amended and Restated Registration Rights Agreement, dated January 2, 2019, which requires SAFE to, among other things, use commercially reasonable efforts to file with the Securities and Exchange Commission within six months after the purchase of the Investor Units a shelf registration statement providing for resale of all Shares held by iStar.  The agreement

6

also provides iStar with certain demand registration rights.  The agreement amends and restates the Registration Rights Agreement, dated as of June 27, 2017, between iStar and the Issuer.

The Issuer has entered into voting agreements with each of SFTY Venture LLC, an affiliate of GIC (Realty) Private Limited, and SFTY VII-B, LLC, an affiliate of Lubert-Adler, L.P., pursuant to which they have agreed to vote their Shares to approve the issuance of Shares upon the exchange of Investor Units and the grant of the preemptive rights described above to iStar at the stockholder meeting called for such purpose.  The voting agreements expire on June 30, 2019.  Dean Adler, a principal of Lubert-Adler, L.P., is a director of the Issuer.  SFTY Venture LLC owns 2,125,000 Shares and SFTY VII-B, LLC owns 750,000 Shares at the date of this Report.

The preceding descriptions of certain transaction documents are qualified in their entirety by reference to the full text of the Investor Unit Purchase Agreement, the Partnership Unit Designation of Investor Units, the Stockholder’s Agreement, the Amended and Restated Management Agreement, the Amended and Restated Registration Rights Agreement and the Voting Agreements, copies of which are incorporated by reference as exhibits to this Statement.
