What Gross & Partner does

Groß & Partner is a privately held German real estate development company founded in 1992 and headquartered in Frankfurt am Main. It operates across the full real estate value chain via three wholly-owned subsidiaries: GP Con (structural construction, including on-site precast element production), GP Log (construction logistics), and GP Sales (residential and commercial leasing/brokerage). At the parent level the business spans project development, project management, financial accounting/controlling/legal, acquisition/financing/marketing, ECO-Consulting for ESG compliance, and real estate fund offerings. The company develops landmark mixed-use urban quarters, office towers, residential buildings, hotels, and retail, with flagship project FOUR Frankfurt — a ~213,000 m² four-tower (T1-T4, 105-233 m) development — alongside the NION office tower in Europaviertel (45,000 m², DGNB Platinum-design) and the KAIA office at Untermainkai (25,830 m², Manage-to-Green revitalization saving ~70% emissions versus new build).

The company monetizes via one-off property sales to institutional investors (e.g., the T1 disposition to PIMCO/Allianz/Universal-Investment/BVK for at least €55M in April 2025, T4 to Union Investment in November 2023), recurring rental income and pre-leasing of office, hotel, residential, and retail space, construction and logistics services billed by subsidiaries to internal and third-party projects (Samson AG, ABG Frankfurt, BLB NRW), and capital-markets activity via corporate bond issuances (€50M at 10% coupon maturing May 2028, refinancing a 2020/2025 bond at 5%). Distribution is relationship-driven B2B, relying on direct negotiation with corporate tenants (DekaBank, Boston Consulting Group, Allen & Overy, Freshfields, Sanofi, Baker McKenzie, Invesco, Lazard, Peak One, KLIEMT, Compass Group/Food Affairs, Radisson Collection, Kimpton Main Frankfurt) and brokers such as Avison Young, JLL, and blackolive advisers.

The technology stack is anchored in sustainable construction IP rather than software: DGNB Platinum certification on FOUR Frankfurt (first "sustainable vertical city" globally for full deconstruction), ECARF allergy-friendly quality seal, Cradle-to-Cradle design principles, CRREM-aligned decarbonization pathways, grey-energy reduction targets below 500 kg CO2e/m², and a 400-hectare reforestation initiative in the Rothaar Mountains partnered with Cara Investment and Colliers Land & Forst. After a high-double-digit-million EUR negative IFRS result in FY2024 driven by project valuation adjustments, management guides to a mid-double-digit-million EUR positive IFRS result in FY2025 anchored on the T1 closing; liquidity and bond-market access were maintained. The company is also the indirect beneficiary of AI-driven data-center demand via GP Con's 2024 contract with Green Mountain KMW Data Center in Mainz.

Revenue model

1. Property Development & Sales: Groß & Partner acquires land, develops large-scale real estate projects (mixed-use quarters, office towers, residential buildings, hotels), and generates revenue through sales of completed properties or units to investors, owner-occupiers, or joint ventures. Revenue recognition occurs upon delivery/transfer. Example: sale of T1 FOUR to PIMCO Prime Real Estate for approx. €55M.
2. Property Rental & Lease Income: Commercial and residential properties developed by the company generate recurring rental income from tenants before or after sale to investors. GP Sales handles leasing of residential and commercial units across the portfolio.
3. Construction & Realization Services (via Subsidiaries): Three 100% subsidiaries — GP Con (construction/structural work), GP Log (construction logistics), and GP Sales (brokerage/marketing) — provide services across the real estate value chain. Revenue is generated through construction contracts, logistics fees, and brokerage commissions, both for internal Groß & Partner projects and external clients.
4. Corporate Bond Issuance: Groß & Partner raises capital through corporate bond issuances (e.g., €50M, 10% coupon 2024/2028; previously €12.69M, 5% coupon 2020/2025 repaid in 2025). Bonds are offered to institutional investors via the investor relations website.
