SL Green Names Sitomer President in Bet on Homegrown Leadership

NEW YORK, NY – March 02, 2026 – SL Green Realty Corp., Manhattan’s largest office landlord, announced a significant leadership move today, promoting Harrison Sitomer to the dual role of President and Chief Investment Officer. The promotion solidifies a long-planned leadership trajectory for Sitomer and is coupled with contract extensions for two other key executives, underscoring the company's strategy of cultivating stability amidst a dynamic commercial real estate landscape.

In a concurrent move to reinforce its senior ranks, the real estate investment trust (REIT) extended the contracts of Chief Financial Officer Matthew DiLiberto and Chief Operating Officer Edward Piccinich through the end of 2028. Together, the announcements signal a deep commitment to an executive team that boasts an average tenure of over two decades, a rarity in the fast-paced world of New York real estate.

An Intern's Ascent to the Presidency

Harrison Sitomer's promotion is the culmination of a career spent entirely within SL Green. His journey from a company intern to the firm’s number two executive, behind Chairman and CEO Marc Holliday, serves as a powerful testament to the company's stated focus on nurturing internal talent. The role of President had been vacant since Andrew Mathias stepped down at the end of 2023, making Sitomer's appointment a pivotal moment in the company's succession planning.

After steadily rising through the organization in various investment-focused roles, Sitomer was appointed Chief Investment Officer in January 2022. In that capacity, he was tasked with sourcing and executing the company's acquisitions, dispositions, financings, and joint ventures.

“Harry exemplifies the dedication, tenacity and strength that define SL Green. This promotion reflects his achievements and our continued commitment to growing talent from within,” said Marc Holliday in a statement. “On behalf the leadership team and the Board of Directors, it has been a pleasure to see Harry grow from an intern into a leader. His entire career has been shaped here, and his commitment to our culture, our stakeholders and our city is unwavering.”

A Strategic Architect of Capital and Growth

Sitomer's impact as CIO has been substantial, particularly in fortifying SL Green’s financial and strategic positioning. He has been a central figure in developing and executing the company's strategy, playing a critical role in strengthening its capital platform by identifying and securing new domestic and international capital sources.

One of his most notable achievements was spearheading the launch and successful fundraising for the SLG Opportunistic Debt Fund. Kicked off in 2024 with a $1.0 billion target, the fund capitalized on market dislocations and quickly gained momentum, securing over $500 million in new commitments in a single week in mid-2025. By its final closing in December 2025, the fund had surpassed its initial goal, raising over $1.3 billion from institutional investors worldwide. This initiative positioned SL Green to strategically deploy capital into high-quality New York City assets at a time of evolving debt markets.

Beyond the debt fund, Sitomer is credited with expanding the nation's leading commercial mortgage servicing platform and advancing the company's growing asset management business. His portfolio of responsibilities also includes managing the Food1st Foundation, a 501(c)(3) nonprofit established by SL Green that has provided over one million free meals to New Yorkers since the COVID-19 pandemic began.

Betting on Stability in a Bifurcated Market

The decision to lock in its senior leadership team comes as SL Green navigates a Manhattan office market characterized by a distinct “flight to quality.” While 2025 saw a surge in leasing activity—with some reports pegging it as the strongest year since 2014—the demand has been highly concentrated. Newly constructed, modernized, and Class A trophy buildings are commanding strong interest and higher rents, while older, less-amenitized Class B and C properties face significant headwinds.

Data from late 2025 illustrates this divide. While the overall Manhattan availability rate fell to 15.5%, trophy space boasted a much lower vacancy rate of just 6.4%. This bifurcation requires a nuanced strategy, balancing the management of a vast portfolio that includes interests in 56 buildings totaling 31.4 million square feet with the need to invest in and capitalize on top-tier assets. The continued trend of office-to-residential conversions is also reshaping the landscape, absorbing obsolete inventory and structurally rebalancing supply.

By extending the contracts of CFO Matthew DiLiberto and COO Edward Piccinich, SL Green ensures that the operational and financial helms are manned by seasoned executives with deep institutional knowledge. This stability is viewed as a critical asset for steering the company through a market that, despite a robust 2025, showed signs of moderation in early 2026. Experts predict the year ahead will be defined by selectivity and differentiation, favoring landlords with the experience and strategic clarity to adapt.

Navigating Investor Scrutiny and Financial Headwinds

While the leadership announcements project confidence, they arrive at a time of mixed sentiment among investors and analysts. On the same day as the promotion, CEO Marc Holliday, speaking at Citi's 31st Annual Global Property CEO Conference, cited “leadership” as the primary reason to own SL Green stock, directly referencing the day’s executive news.

However, some market watchers remain cautious. Financial analysis from firms like GuruFocus points to a “hold” recommendation and flags the company’s high debt levels as a primary concern, contributing to a poor financial health rating despite high institutional ownership of nearly 98%. The company's stock, while showing some resilience, has reflected the broader uncertainties facing the office sector.

The newly solidified leadership team, led by Holliday and Sitomer, is therefore tasked not only with navigating the property market but also with convincing the financial markets that its strategy of focusing on premium assets and leveraging its deep leadership experience can overcome these financial headwinds. Their ability to execute on capital deployment through vehicles like the new debt fund while managing a massive existing portfolio will be under intense scrutiny as they chart the company's course through 2026 and beyond.
