Tim Mattke joined MGIC in 2006. For someone whose business would be mortgage insurance, the calendar had a rather dark sense of humor. The housing market was approaching a crisis that would turn the ability to judge a loan, absorb a loss and keep a promise into questions of survival. Mattke arrived from auditing. He would spend the next thirteen years moving through the accounts before taking responsibility for the company.
His path offers a different sort of executive story: an accountant learning a business from inside its financial machinery, then becoming its public voice. Today he leads MGIC and its parent, MGIC Investment Corporation, from Milwaukee. In June 2026, he also became chairman of U.S. Mortgage Insurers, the trade association for private mortgage insurers. His subject is a familiar American ambition with some decidedly unromantic arithmetic attached: buying a home.
A long memory for a short boom
Before MGIC, Mattke was an audit manager at PricewaterhouseCoopers. His Wisconsin education preceded that work. He earned his BBA at the University of Wisconsin-Madison in 1998 and his Master of Accountancy there in 1999. The training matters to the shape of his career. Accounting supplies a language for testing claims, following obligations and noticing when a pleasing number is concealing an unpleasant one.
At MGIC, he worked in accounting and finance before becoming controller in 2009. He held that position until 2014, then served as executive vice president and chief financial officer until 2019. The dates put his apprenticeship squarely inside the company's encounter with the housing collapse and its aftermath. MGIC continued writing new insurance throughout the financial crisis, including the years from 2008 to 2013.
By March 2018, Mattke was speaking alongside finance executives from Arch Mortgage Insurance and Radian at an RBC conference. He described favorable credit conditions, then immediately returned to the experience of the crisis. He emphasized the industry’s memory of the downturn. It is a revealing qualification. A pleasant market can be enjoyed without being mistaken for a permanent climate.
“Long memories about what happened during that.”

That conference appearance gives his later language about discipline some history. He was already discussing underwriting standards and the lessons of a downturn while serving as CFO. The caution came before the chief executive's title. In insurance, remembering the last unpleasant surprise is part of preparing for the next one.
The promotion came with company
On July 25, 2019, Mattke succeeded Patrick Sinks as CEO and joined the board. The announcement also promoted Salvatore Miosi to president and chief operating officer and Nathaniel Colson to executive vice president and CFO. Mattke's advancement belonged to a broader internal succession. Sinks pointed to MGIC's tradition of developing its own leadership; Mattke emphasized the experience of the team around him.
There is something useful in that ensemble cast. A CEO biography tends to arrange everyone else as scenery. This transition explicitly distributed responsibility among executives who already knew the company. Mattke had spent thirteen years there. Miosi had joined in 1988. Colson had worked at MGIC since 2014. Institutional memory was present in several chairs around the table.
Mattke inherited a company with a much longer story. Max Karl founded MGIC in Milwaukee in 1957. The business helped establish the modern private mortgage insurance industry, giving lenders another means of supporting buyers with smaller down payments. Mattke entered that history as a financial employee and became its custodian. The founder's problem remained recognizable decades later: a household can have the capacity to pay a mortgage before it has accumulated a large pile of cash.
The number that stops a conversation
Twenty percent has an extraordinary grip on the American homebuying imagination. In a 2021 interview, Mattke argued that renters sometimes rule themselves out before exploring their options. The assumption that they must first save a 20 percent down payment can postpone the conversation entirely. His concern was that a familiar rule of thumb had become an entrance requirement in people's minds.
He described MGIC's efforts to make the process easier to understand through homebuyer education and Readynest, its consumer website. His emphasis was on information: helping prospective buyers understand the process before deciding when to purchase. That argument also serves MGIC's business. More awareness of low down payment mortgages can mean more demand for the insurance the company sells. The commercial incentive belongs in the picture.

over time
His public position links access to protection against mortgage credit losses. The insurer has to remain able to meet its obligations as conditions change. The appeal of an earlier purchase therefore sits alongside the less photogenic work of maintaining capital and assessing risk. A key can make a fine advertisement. An insurance balance sheet needs rather more explanation.
Inside the office, Tim talks
One of the more personal details of Mattke's management is also among the plainest: a monthly employee video series called “Tim Talks.” During 2024, its subjects included market developments, company strategy, sustainability and early talent. The format gave employees a regular way to hear from the CEO about what the company was doing and why.
MGIC also used CEO listening sessions, employee surveys and an annual company meeting. Those practices do not establish a personality type, but they show how communication was organized during his tenure. The chief executive's job included explaining decisions to colleagues, as well as discussing performance with investors. For a business full of specialized terms, regular explanation is practical work.
His message introducing MGIC's code of conduct supplies another piece of the management picture: “We care about doing things the right way”. The document connects business decisions to responsibilities involving information, colleagues and the company's reputation. It gives the claim some actual subjects. Integrity becomes easier to assess when it reaches the handling of data and the treatment of people.
The balance sheet gets a vote
The numbers provide a separate test. In August 2025, Moody's upgraded MGIC Investment Corporation's senior unsecured debt rating from Baa3 to Baa2 and MGIC's insurance financial strength rating from A3 to A2. The rationale included consistent performance, capital generation, profitability and capital adequacy. These were company outcomes under Mattke's leadership, produced by an organization rather than a single executive.
For the full year 2025, MGIC Investment Corporation reported net income of $738.3 million. It ended the year with $303.1 billion of primary insurance in force, covering 1.1 million mortgages. The company also returned $915 million to shareholders through dividends and share repurchases. Each measure describes a different part of the enterprise: earnings, the mortgage book and decisions about capital.
By the second quarter of 2026, the company reported net income of $182.1 million and an annualized return on equity of 14.5 percent. The scale brings Mattke's work back to its central tension. Shareholders expect returns; customers require a counterparty that can pay claims. Managing a mortgage insurer means giving both demands room in the same business.
Milwaukee has a part in the accounts
Mattke's civic commitments make the story more geographically specific. In 2025 he co-chaired the United Performing Arts Fund's community campaign with Peggy Williams-Smith, president and CEO of Visit Milwaukee. His case for supporting the arts included their contribution to the workforce and their ability to attract talent. Culture, in this telling, belongs in a business discussion about the city.
That campaign raised $9,101,255. Its Funding Day celebration took place at the Milwaukee Youth Arts Center on October 9, 2025, recognizing the co-chairs and the donors and organizations involved. The money supported performing arts organizations and community programs. It was a collective result, with Mattke taking a public fundraising role alongside people whose work was onstage, in classrooms and behind the scenes.
His support also became a matter of neighborhood policy. In September 2025, Mattke wrote to the Milwaukee County Board in favor of a proposed five-year operating agreement for the Marcus Performing Arts Center. He described MGIC's financial and practical support for the center and nearby Red Arrow Park. An employer's interest in its surroundings becomes quite concrete when the park and performance venue are neighbors.
Housing provides another local connection. Mattke serves on the board of Acts Housing, which announced in October 2024 that it would move into furnished space at MGIC's downtown headquarters. The relationship included technical assistance, board service and financial and in-kind support. Here, the national business of helping finance homeownership met a Milwaukee organization working directly with families.
A wider room, the same argument
Mattke's appointment as USMI chairman in June 2026 extended his responsibilities beyond MGIC. He succeeded Enact CEO Rohit Gupta, taking a role that involves speaking for an industry of competitors. He described private mortgage insurance as a means of helping households buy with smaller down payments while limiting mortgage credit exposure for lenders, investors and taxpayers.
His advocacy now includes asking bank regulators to give mortgage insurance greater recognition in capital requirements. In a public post discussing his American Banker opinion piece, he argued that the rules should reflect the protection the product provides. It is a policy position with direct consequences for his industry, and a continuation of the questions he encountered in finance: who bears a loss, and how should that protection be counted?
The career that began in audit has arrived at that larger argument. Mattke's responsibilities run from the employee video to the investor call, from a Milwaukee nonprofit board to national housing policy. The through line is the promise beneath the paperwork. A company offering protection has to explain its value, maintain the means to provide it and keep showing up when the market becomes less agreeable.
