Mattamy Homes announced Thursday that Keith Bass, who has led the company's U.S. operations since 2020, will retire effective Sept. 1, 2026. The company said Chris Lindhorst, currently chief operating officer of Mattamy Homes U.S., will assume the role of chief executive officer on the same date.
Transition timed as the company plans its next growth phase
The change at the top comes after a period the company described as one of significant expansion and volatility in the homebuilding sector. During Bass’s tenure, Mattamy Homes’ U.S. business achieved what the company called record results in revenue, earnings and community counts while navigating shifting market conditions.
"Keith has been an exceptional leader for Mattamy Homes U.S. during an important chapter in our company's history," said Larry Nicholson, vice chair of Mattamy Homes.
In the announcement, Nicholson praised Bass’s steady leadership, commitment to employees and operational focus, and he thanked Bass for his contributions while wishing him well in retirement.
New CEO brings extensive homebuilding operations experience
Lindhorst joined Mattamy earlier in 2026 as chief operating officer and has worked closely with Bass and the senior management team in preparing for the company’s next stage. The company noted he brings more than two decades of leadership experience in homebuilding.
Before joining Mattamy, Lindhorst spent over 16 years at D.R. Horton in a series of advancing leadership roles. His most recent position there was regional president, where he oversaw operations responsible for more than 13,000 annual home closings across 11 markets in Texas, Arizona and New Mexico, according to the company statement.
"Chris is a proven leader with deep operational expertise and an impressive track record of delivering results at scale," Nicholson said.
What the change means for stakeholders
The appointment of an internal senior executive who has worked closely with the outgoing CEO signals continuity in strategy and operations, the company suggested. Lindhorst's operational background—particularly his experience managing large-scale closing volumes—may be positioned to support Mattamy’s plans for growth in the competitive U.S. homebuilding market.
- Effective date: Sept. 1, 2026 — Bass retires; Lindhorst becomes CEO.
- Leadership background: Lindhorst joined Mattamy in February 2026 as COO; previously 16+ years at D.R. Horton.
- Scale reference: Oversaw operations accounting for more than 13,000 annual home closings in prior role.
Mattamy Homes did not release additional financial details or forward guidance tied explicitly to the leadership change in the PR distribution. The company emphasized that Bass had been instrumental in strengthening and expanding the U.S. arm during extraordinary market conditions.
Industry context
The homebuilding industry has experienced notable swings in demand, costs and regulatory pressures in recent years, factors Mattamy said it navigated under Bass’s leadership. Leadership transitions at major builders can influence investor sentiment, supplier and subcontractor relationships, and local market operations, particularly when the successor has a strong operations background and experience managing high-volume closings.
| Executive | Role | Effective |
|---|---|---|
| Keith Bass | Chief Executive Officer, Mattamy Homes U.S. (retiring) | Sept. 1, 2026 |
| Chris Lindhorst | Chief Executive Officer, Mattamy Homes U.S. (appointed) | Sept. 1, 2026 |
The company framed Lindhorst’s hire and promotion as part of preparing for a new chapter of expansion. Stakeholders will be watching how the new chief executive leverages his operational track record to sustain the company’s recent performance and address the ongoing challenges facing national and regional builders.
