When Wealth Moves Sideways: What Horizontal Transfers Mean for Martin Marietta Materials Households

Healthcare Provider Update: Healthcare Provider for Martin Marietta Materials The healthcare provider for Martin Marietta Materials is primarily UnitedHealthcare. They offer a range of health insurance plans to employees, which typically include various coverage options catering to both individual and family needs. Potential Healthcare Cost Increases in 2026 As we look toward 2026, Martin Marietta Materials anticipates significant challenges as healthcare costs are projected to rise substantially, driven by several factors. The expiration of enhanced ACA subsidies may lead to a surge in premiums, with some states witnessing increases of over 60%. Additionally, industry-wide medical costs are expected to rise by approximately 8.5%, spurred by ongoing inflation in healthcare services and the increasing costs of prescription drugs. This confluence of factors means that many employees could face a steep increase in their out-of-pocket expenses, compelling the company to consider strategic adjustments to its health benefits offerings.

'Martin Marietta Materials employees should treat the first spouse’s death as a bracket stress test—model RMDs early, pace Roth conversions, engage both partners, and coordinate with tax and legal professionals before surprises hit.' — Brent Wolf, a representative of The Retirement Group, a division of Wealth Enhancement.

'For Martin Marietta Materials employees, charting how assets shift to a surviving spouse can reduce unexpected surprises. Talking to qualified tax and estate advisors can help.' — Brent Wolf, a representative of The Retirement Group, a division of Wealth Enhancement.

In this article, we will discuss:

1. The horizontal transfer of wealth between spouses and its growing impact on estate planning for Martin Marietta Materials families.

2. The tax implications of Required Minimum Distributions (RMDs) and strategic Roth conversions to manage income brackets and help preserve assets.

3. The evolving role of charitable giving and spousal financial engagement in shaping effective multi-generational legacy plans.

Major wealth transfers are anticipated over the coming decades. By 2045, more than $84 trillion is expected to change hands—$11.9 trillion to charities and $72.6 trillion to heirs and family members ¹ —and many of those dollars will first move “across” to surviving spouses rather than straight “down” to children.

Because women often live longer than men, a sizable share of assets may shift laterally to widows before any vertical bequests occur, a point stressed by Wealth Enhancement senior wealth advisor Mike Corgiat. This is important for Martin Marietta Materials retirees with sizable IRAs to note. 

Pre-boomer generations are projected to pass $15.8 trillion in the next decade, while baby boomers may transfer nearly $53 trillion ¹ —frequently after the first spouse dies—illustrating how wealth rarely travels in a clean vertical line. 

This horizontal detour has real implications for required minimum distributions (RMDs), retirement savings, and estate tax exposure that can affect Martin Marietta Materials employees late in retirement.

Current rules require RMDs to begin at age 73 for those born 1951–1959 and at 75 for those born in 1960 or later, and a surviving spouse can often roll an inherited IRA into their own to delay distributions—sometimes compressing taxable income into fewer years.

Brent Wolf, a retirement income planner with Wealth Enhancement, notes that once RMDs start and the survivor files as single, identical withdrawals can land in higher brackets—an issue that can surprise a survivor when income sources are already shifting.

Strategic Roth conversions while both spouses are alive—often in the 60s or early 70s—may help trim future RMDs and give the survivor more control, a tactic many Martin Marietta Materials retirees may want to evaluate while they still benefit from joint tax brackets.

Corgiat emphasizes that conversions executed at comparatively lower rates can lessen the tax hit on both the survivor and heirs, while Wolf adds that thoughtful timing lowers the odds of large, forced taxable withdrawals later—key considerations for Martin Marietta Materials employees eyeing estate efficiency.

Philanthropy is shifting too, as more affluent families embrace “living legacy” giving so they can witness impact, but a sudden asset windfall can delay or confuse charitable intent if the less-involved spouse isn’t already engaged in the broader plan. 

Wolf recommends that spouses who haven’t driven the finances start participating early, since many women may ultimately steer multimillion-dollar portfolios and will benefit from hands-on experience before the transfer moment arrives. 

Coordinated planning across tax, investment, and estate disciplines can answer pivotal questions for Martin Marietta Materials retirees: How large might RMDs become with only one personal exemption? Would spreading Roth conversions over several years keep income in more favorable brackets? Are beneficiary designations current on retirement plans and insurance? Do charitable goals call for donor-advised funds, qualified charitable distributions (QCDs) from IRAs, or a family foundation? Has the estate been reviewed for credit shelter or portability strategies and potential federal or state estate taxes?

The death of the first spouse often triggers the most dramatic ownership and tax changes, so acting earlier—stress-testing single-life cash flows, harvesting gains or losses, accelerating withdrawals in low-income years, and reviewing insurance and titling—can materially influence outcomes for Martin Marietta Materials retirees.

Those headline numbers—$84.4 trillion overall, $72.6 trillion to heirs, $11.9 trillion to charities—signal the size of what’s coming, but the net amount that actually arrives depends on how transfers occur and which tax rules apply, especially for families with layered benefits and investments.

As this horizontal phase of wealth transfer approaches, Martin Marietta Materials employees may benefit by preparing actively to pass the baton to a suriving spouse.
