A conversation between neighbors helped set Mueller Industries on the road to a new headquarters. Kevin Hyneman knew Greg Christopher from Southwind, knew the company’s office lease was approaching its end, and had a suggestion: a site in Collierville’s Schilling Farms. Mueller examined other possibilities. Eventually, it chose the first lot Hyneman had shown Christopher in early 2016. Even an industrial company with international operations can find its next address through a familiar conversation.
The proposed building was substantial: 55,000 square feet, with a reported price of $14.5 million. The beginning of the story was pleasingly ordinary. Someone knew someone. Someone had a piece of land. Then came the longer work of considering alternatives. It is a useful opening to Christopher’s career because it puts a recognizable human exchange beside the machinery of a public company.
Christopher’s professional story has that same combination of continuity and change. He has spent more than three decades at Mueller, a business whose products tend to disappear into the buildings and equipment they serve. Copper tubing rarely gets the architectural photograph. It does, however, get a great deal of the work.
Fifteen years before the corner office
Christopher joined Mueller in 1992. Before becoming chief executive, his responsibilities included sales, manufacturing, distribution and supply chain management. That range matters in a company where making something and getting it to the customer are inseparable problems. A factory can run efficiently and still disappoint a buyer if the right product arrives at the wrong time.
In October 2007, Mueller appointed him chief operating officer. He had previously led its Standard Products Division. The promotion placed an experienced internal executive over the daily operation of a business built around physical goods, production schedules and customers with their own deadlines. By then, he had already spent roughly fifteen years learning the organization from within.
He became CEO on October 30, 2008. Consider the calendar. The financial crisis was unfolding, and building activity was under pressure. Mueller’s operating income for that year fell to about $126.1 million from $191.6 million in 2007. Its annual report recorded U.S. housing starts falling from 1.4 million to 0.9 million. These were the conditions surrounding his arrival in the top job.
For a manufacturer tied to construction, fewer starts mean fewer opportunities for products to find a home. The immediate challenge was concrete, in both senses: what could the business produce, sell and support while demand contracted? Christopher inherited responsibility for an established enterprise at a moment when experience with its moving parts had particular value.
A longer appointment
In July 2015, Mueller announced another step: Christopher would become chairman on January 1, 2016. Gary Gladstein, then chairman, would become lead independent director. Christopher’s authority now extended across executive leadership and the board chair, with an independent director occupying a separate leadership role. The arrangement made the relationship between management and oversight part of his job as well.
There is a temptation to tell a corporate career entirely through promotions. The dates are tidy; the work between them is less cooperative. Christopher’s progression suggests something slower than a succession of new business cards. He stayed with a company whose opportunities and constraints he had encountered through several different functions. Becoming chairman added another responsibility to that accumulated familiarity.
Seven words kept behind the factory gate
One revealing exchange came in a 2023 interview. Asked to give examples of Mueller’s approach to reaching customers, Christopher answered: “Please allow us to skip examples.” He regarded the approach as commercially valuable and preferred to keep its particulars private. The sentence has the economy of someone closing a gate without making a scene.
It is an amusing moment in a conversation about business strategy. Interviewers reasonably want detail. Competitors reasonably enjoy reading it. Christopher found a courteous way to disappoint both audiences at once. The exchange illustrates his handling of that particular question: clear about the importance of customer relationships, guarded about the mechanics.
“Please allow us to skip examples.”

A different emphasis appears in his observation about joining the company: “What was evident from the start was the spirit of the people.” The two remarks sit comfortably together. One concerns the people who make an organization work. The other concerns information an organization has reason to protect. Warmth and commercial discretion can share an office.
What a larger sales number can hide
The financial record needs some of the same care with detail. In 2025, Mueller reported $4.18 billion in net sales and $958.5 million in operating income. Sales rose 10.5 percent; operating income rose 24.4 percent. Net income reached $765.2 million. These were company results achieved under Christopher’s leadership, with the work distributed across its businesses and employees.
The fourth quarter supplied a useful complication. Sales increased even as unit volumes in core copper and brass products declined. Rising raw material costs had pushed selling prices higher. A larger revenue figure can therefore describe more expensive metal passing through the business, rather than more pieces leaving its factories. The distinction keeps a growth story honest.
The year also included a $41.1 million gain on insurance proceeds and a $25.9 million gain on asset disposals within operating results. Those items belong in the picture alongside factory performance. Reading the numbers carefully gives Christopher’s record a firmer footing than treating every additional dollar of reported profit as an identical achievement.
Three measures, three different speeds
Reported company results. Bar lengths use a common scale; operating income includes gains on insurance proceeds and asset disposals.
The next decision was in Oklahoma
On March 30, 2026, Mueller acquired Bison Metals Technologies, a copper tube manufacturer with a single manufacturing location in Shawnee, Oklahoma. Christopher described benefits that were specific to the production system: more domestic tube capacity, broader industrial tube capabilities and more feedstock for Mueller’s value-added products. Feedstock is the material that becomes the input for another manufacturing operation.
He also identified an immediate economic purpose. Producing more of that material domestically could mitigate tariffs being incurred on feedstock made by foreign subsidiaries for use in American operations. Geography, in this explanation, enters the factory accounts. Where a tube is made can affect the cost of the next product in the chain.
The acquisition is a useful example of an executive decision that can sound abstract until followed through the plants. A purchase changes capacity. Capacity changes sourcing choices. Sourcing choices change costs. Whether the expected benefits arrive depends on what happens after the transaction, when the equipment, people and orders have to work together.
The colleagues who span the decades
Christopher’s tenure overlaps with other long careers at Mueller. Chief financial officer Jeffrey Martin joined in 1996 and has held his current executive finance role since February 2013. General counsel Christopher Miritello arrived in 2015 and became executive vice president, general counsel and secretary in January 2017. The leadership group brings different functions to decisions that touch production, capital and corporate obligations.
In August 2026, Mueller announced that Gladstein would retire from the board at year-end after a combined thirty years of service. Christopher’s acknowledgment reached back to the company’s emergence from bankruptcy in the early 1990s. His own arrival in 1992 belongs near that starting point. The connection gives the board transition the weight of a shared institutional history.
Long tenure can be measured as elapsed time. It can also be understood as repeated encounters with the consequences of earlier decisions. A leader who remains through successive investment cycles gets to see whether a promising acquisition integrates, whether a plant improvement pays back, and whether customers return. Christopher’s career provides a particularly long interval over which to ask those questions.
Still following the demand
By October 20, 2026, the next set of results had arrived. Mueller reported third-quarter net sales of $1.42 billion and net income of $221.2 million. Christopher pointed to U.S. data center expansion and other commercial construction as contributors to demand, while residential construction remained weak. The company’s product mix was responding to buildings being commissioned for different purposes.
The accompanying quarterly filing made the revenue movement more precise: higher selling prices contributed $198.6 million, higher core unit sales volumes added $83.5 million, and Bison contributed $52.2 million. Those separate components show why the headline number deserves a second look. Price, existing operations and an acquisition each had a part.
Christopher’s stated priorities included investment in North American manufacturing, lower costs, reshoring production, additional products and broader distribution. These are plans whose progress will be visible in operating results over time. They also bring his career back to familiar ground: how goods are made, where they are made, and how they reach the next customer.
The headquarters conversation began with a suggestion and continued through a search. His larger professional story follows a comparable rhythm: familiarity, a decision, then the work of seeing it through. From the office in Collierville to the production floor in Shawnee, there is plenty left to do before any pipe disappears neatly behind a wall.
