## About

Miramar Holdings was formed in 2012 by John W. Carpenter III and his wife Cele Briscoe Carpenter to unify the investment activities of two distinct Texas family enterprises. The Briscoe lineage traces to South Texas ranching and oil-and-gas holdings concentrated in Uvalde, Webb, and Dimmit Counties, while the Carpenter side built the 12,000-acre Las Colinas master-planned community in Irving — one of the largest private real estate developments in the United States. Their son Benjamin H. Carpenter II is the second-generation lead on the investment team, having previously served as an analyst at Blackstone. The firm operates as a multi-strategy allocator with a heavy tilt toward direct real assets and operating-company control. In real estate, Miramar owns the Las Colinas mixed-use holdings, a Lewisville multifamily project, an industrial portfolio in the Midwest, the Sinclair Market commercial center in Winnsboro, and a landmark retail outlet in Valletta, Malta. On the private equity side, the firm targets buyout-stage companies across Enterprise Software, EdTech, Healthcare Services, Industrial Tech, Supply Chain & Logistics, Marketing & Sales, and Workflow Automation. The family also retains direct ownership of oil-and-gas mineral rights under the Briscoe Ranch lands and manages active ranching operations. Miramar co-invests regularly; disclosed partners include TRT Holdings (the Robert Rowling family office) and Roofstock in the Vacasa going-private transaction. Benjamin Carpenter runs the investment function alongside a team of roughly 16 professionals operating from Freedom Place at Old Parkland in Dallas. The firm has not disclosed total deployment, but its footprint spans direct real estate equity, private credit, natural resources, and public securities — all held without outside LP pressure. The family directs philanthropic efforts through the Briscoe Carpenter Livestock Center and the Briscoe Western Art Museum, while Cele Briscoe Carpenter participates in the Dallas Women's Club and Benjamin Carpenter serves on multiple advisory councils for the McCombs School of Business at UT Austin. Miramar's architecture as a permanent-capital vehicle backing operating ranch assets alongside institutional co-investments gives it a distinct posture: it can hold land and minerals indefinitely while simultaneously partnering with firms like Blackstone on energy assets — a capital base that faces no redemption risk and no arbitrary fund-life limits.

## Questions

### Who runs investment decisions at Miramar Holdings?

John W. Carpenter III is the founding principal, but his son Benjamin H. Carpenter II leads the investment team day-to-day. Benjamin trained at Blackstone before joining the family office, and the broader investment team includes at least 16 professionals operating from the firm's Dallas headquarters.

### What investment stages does Miramar Holdings typically target?

The firm targets buyout-stage opportunities. Its sector focus spans Enterprise Software, EdTech, Healthcare Services, Industrial Tech, Supply Chain & Logistics, Marketing & Sales, and Workflow Automation. Miramar seeks control or significant minority positions in companies where it can align with management teams over extended holding periods.

### Which sectors does Miramar Holdings explicitly avoid?

Miramar explicitly does not invest in distressed or turnaround situations. The firm describes itself as a growth-oriented investor seeking high-quality management teams and durable business models — a posture inconsistent with the complexity and balance-sheet risk typical of distress investing.

### How is the Briscoe-Carpenter family wealth structured across generations?

Wealth originates from two sources: the Briscoe family's South Texas ranching and oil-and-gas holdings, and the Carpenter family's development of Las Colinas, a 12,000-acre master-planned community in Irving, Texas. John W. Carpenter III and Cele Briscoe Carpenter consolidated these assets under Miramar Holdings in 2012, with their son Benjamin now leading the investment team and other children — Austin and Bonner — also affiliated with the family office.

### Does Miramar Holdings maintain philanthropic structures, and how are they separated?

Yes. The family directs philanthropy through the Briscoe Carpenter Livestock Center and the Briscoe Western Art Museum in San Antonio. Cele Briscoe Carpenter is active in the Dallas Women's Club, and Benjamin Carpenter serves on advisory councils for the McCombs School of Business at UT Austin. Philanthropic activities are distinct from the investment portfolio, though both are coordinated from the family office.

### What is Miramar Holdings' known posture on co-investments alongside external GPs?

Miramar actively co-invests. Its most visible partnership is with TRT Holdings, the family office of Robert Rowling, with whom it co-invested in Vacasa and Patriot Family Homes. The firm also partnered with Roofstock on the Vacasa going-private deal and with Blackstone on Sanchez Energy assets — reflecting a model where Miramar contributes permanent capital to sponsor-led transactions.
