Miller & Long Employees Combined Retirement Plan
John M. McMahon oversees a $68.9M retirement plan for Miller & Long employees, administered by Principal Financial Group.
Miller & Long Employees Combined Retirement Plan
The Miller & Long Employees Combined Retirement Plan was established in 1989 to serve the workforce of Miller & Long Co., Inc., the Bethesda-based concrete subcontractor founded by Jack Miller and Jimmy Long in 1947. The plan is a defined-contribution vehicle administered by Principal Financial Group. Its fortunes are intertwined with the parent company, which has poured over 20 million cubic yards of concrete and completed more than $8 billion in construction projects across the Washington D.C. metro area. The plan's investment posture mirrors the operational tempo of a self-performing construction firm. Asset allocation details are not publicly disclosed, but the capital base is modest at $68.9 million (Altss estimate). The parent company generates cash flow from long-standing relationships with developers such as Boston Properties, Brookfield Properties, and JBG Smith, and general contractors including Clark Construction and Whiting-Turner. Major project engagements in the Mid-Atlantic and broader United States landscape provide the economic activity underpinning plan contributions. The plan is administered externally by Principal Financial Group, with oversight from Miller & Long's leadership, including Chairman John M. McMahon and CEO Brett McMahon. John M. McMahon also serves as a director of United Bankshares, Inc., linking the plan's governance to regional banking networks. The parent firm operates additional commercial properties and a construction equipment fleet in the Mid-Atlantic. In December 2022, Miller & Long launched a new website marking 75 years of concrete construction operations, signaling sustained corporate continuity. The plan's structural differentiator is its captive employee base inside a single, multi-generational operating company. There is no marketing apparatus, no third-party capital solicitation, and no independent fund structure. This makes the plan a pure-play reflection of one trade contractor's employment ecosystem, distinct from pooled multi-employer funds in the construction trades.

Frequently asked questions
Who is responsible for overseeing the Miller & Long Employees Combined Retirement Plan?
Oversight falls under the leadership of Miller & Long Co., Inc., including Chairman John M. McMahon and Chairman/CEO Brett McMahon. Day-to-day administration is handled by an external provider, Principal Financial Group, as disclosed in public filings.
How is this plan related to Miller & Long's construction operations?
The plan exclusively serves employees of Miller & Long Co., Inc., the structural concrete subcontractor headquartered in Bethesda, MD. Its asset base and contribution levels are directly supported by the parent firm's construction revenue, drawn from decades-long relationships with developers like Boston Properties and Clark Construction in the Mid-Atlantic.
Is the plan structure a single-employer plan or a multi-employer construction-trades plan?
It is a single-employer defined-contribution retirement plan for Miller & Long's own workforce. The plan is administered by Principal Financial Group. It does not pool contributions across multiple unrelated construction employers, which distinguishes it from typical Taft-Hartley multi-employer plans prevalent in the building trades.
What are the plan's investment strategy and asset allocation?
Miller & Long does not publicly disclose the specific investment policy, asset allocation, or manager lineup for its 401(k) plan. As a corporate retirement plan, it likely offers a menu of mutual funds or collective investment trusts selected by the plan sponsor and its administrator, Principal Financial Group, rather than making direct private-market investments.
How has the plan's asset size changed over time?
The Altss record indicates an asset size of approximately $68.9 million as of 2019. More recent public data on the plan's total asset size is not available. Changes would correlate with participant contributions, market performance, and headcount variations at the parent company.
