D1 Capital's $358 Million Kilroy Realty Bet Signals Major Investor Confidence in Beaten-Down Coastal Office Market

The Big Picture: Institutional Conviction in a Contrarian Play

In a striking move that challenges prevailing sentiment about West Coast office REITs, New York-based D1 Capital Partners has dramatically increased its exposure to Kilroy Realty Corporation (NYSE:KRC), signaling that sophisticated capital still identifies compelling value despite years of headwinds in the commercial real estate sector. According to SEC filings released on November 14, the hedge fund amplified its Kilroy position by approximately 6.6 million shares during Q3 2024.

Inside the Trade: How D1 Built Its $358M Position

The fund’s overall Kilroy stake has grown to roughly 8.5 million shares, now valued at $358.4 million — a quarter-over-quarter value increase of $293.7 million. This holding represents 4.1% of D1 Capital Partners’ total U.S. equity portfolio, a meaningful allocation for a multi-billion dollar fund whose typical focus gravitates toward high-growth technology and industrial equities.

What makes this accumulation particularly noteworthy is timing. Kilroy shares closed Friday at $40.78, having gained merely 1% over the past twelve months, while the broader S&P 500 has advanced 13% in the same window. For a fund with alternative alpha aspirations, backing an underperformer signals either exceptional conviction or a calculated thesis about mean reversion.

Kilroy’s Operational Snapshot

Key Metrics:

• Current Share Price: $40.78
• Market Cap: $4.9 billion
• TTM Revenue: $1.1 billion
• TTM Net Income: $322.1 million
• Portfolio Size: ~17 million square feet
• Focus: Office and life science real estate across West Coast markets

Why D1 Might Be Right: Emerging Positive Signals

The contrarian narrative gains traction when examining Kilroy’s recent operational trajectory. The company’s most recent quarterly results revealed several encouraging data points often overlooked by a market fixated on occupancy rate concerns:

Financial Momentum: Despite revenues declining slightly to $279.7 million from $289.9 million year-over-year, net income surged dramatically to $156.2 million from $52.4 million — a near tripling that reflects improved property-level economics and disposition gains.

Leasing Activity Accelerating: Early-quarter reporting highlighted meaningful leasing spreads, with GAAP rent commencement accelerating. In a REIT market where new lease volume often signifies stabilization, these metrics provide evidence of fundamental healing.

Portfolio Quality Defense: Kilroy maintains a stabilized base of premium office and life science assets in liquidity-constrained coastal markets. Technology, entertainment, life science, and enterprise services companies continue seeking modern, sustainability-focused workspace — a demographic Kilroy serves.

Where Kilroy Ranks in D1’s Portfolio

D1 Capital’s top five holdings as of the SEC filing reveal the fund’s growth-oriented tilt:

• NASDAQ: CART — $829.2 million (9.5% of AUM)
• NASDAQ: APP — $601.3 million (6.9% of AUM)
• NYSE: CLH — $567.9 million (6.5% of AUM)
• NYSE: RDDT — $465.6 million (5.4% of AUM)
• NYSE: FLS — $397.5 million (4.6% of AUM)

Against this backdrop, Kilroy emerges as a tactical departure: a “barbell” holding combining real asset backing with multi-year recovery potential.

The Unresolved Risks: What Could Derail the Thesis

Optimism must be tempered. West Coast office markets face structural headwinds: elevated remote work adoption, flight to suburbs, and cap rate expansion have pressured valuations for years. Kilroy’s occupancy rates remain below pre-pandemic highs, and further weakness could necessitate aggressive writedowns or capital raises.

Additionally, interest rate persistence or a recession could compress cash flows before the occupancy recovery takes hold, potentially invalidating the fund’s timing.

The Takeaway

D1 Capital Partners’ aggressive $358.4 million accumulation of Kilroy Realty shares represents a high-conviction bet that patient capital can exploit dislocations in real estate markets. The fund’s decision to make Kilroy a material 4.1% portfolio position suggests confidence that leasing momentum, improving cash generation, and deeply discounted valuations will compound into meaningful shareholder returns.

For risk-tolerant investors with a multi-year time horizon, the fund’s contrarian positioning warrants serious consideration — particularly if near-term operational improvements prove sustainable.
