VOTING MATTERS AND BOARD RECOMMENDATION

PROGRESSIVE AT A GLANCE

The Progressive insurance organization has been offering insurance to consumers since 1937. We are the second largest private passenger auto insurer in the U.S., the largest writer of motorcycle insurance, the eleventh largest homeowners insurance carrier, and the number one writer of commercial auto insurance, in each case based on 2023 premiums written.

As our name implies, we were founded on the principle of moving forward, taking new risks, and learning and growing together. As we look to the future, we are grounded in our four cornerstones.

OUR CORE VALUES: Who we are

Progressive’s Core Values—Integrity, Golden Rule, Objectives, Excellence, and Profit—serve as the foundation for our culture. They represent our values, guide our decisions, and define how we conduct our business and interact with others.

•Integrity: We revere honesty and adhere to high ethical standards to gain the trust and confidence of our customers. We value transparency, encourage disclosing bad news, and welcome disagreement.

•Golden Rule: We value and respect our differences, act with kindness and caring, and treat others as they want to be treated.

•Objectives: We set ambitious goals and evaluate our performance by measuring what we achieve and how we achieve it. We’re committed to an inclusive and equitable workplace where rewards and promotion are based on results and ability.

2024 BUSINESS PERFORMANCE HIGHLIGHTS

As a property-casualty insurance company offering products throughout the U.S., we have earnings streams from both underwriting activity and investment activity. During 2024, we wrote $74.4 billion of net premiums written, or $12.9 billion more than the prior year, and ended the year with 35 million policies in force, which was an increase of just over 5 million from year-end 2023. Our underwriting profit margin for 2024 was 11.2% (which exceeded our companywide profitability target of at least 4%), or $8.0 billion of pretax underwriting profit, compared to 5.1%, or $3.0 billion, for 2023. The increase in underwriting profit margin over the prior year was primarily driven by the rate increases we took throughout 2023, which increased average earned premiums per policy in 2024, lower loss frequency, and favorable prior-year development, partially offset by increased advertising spend.

Our investment portfolio generated $2.8 billion of recurring investment income earned during 2024, compared to $1.9 billion in 2023. The 50% increase reflected growth in invested assets and an increase in recurring investment book yield. At December 31, 2024, 94% of the total fair value of our portfolio was comprised of fixed-maturity securities. During 2024, the changes in the market value of our fixed-maturity securities, which are a component of comprehensive income, increased $0.2 billion, after tax, due to valuation increases across fixed-maturity sectors, excluding the U.S. Treasury portfolio. For the year ended December 31, 2024, our fully taxable equivalent total return on our investment portfolio was 4.6%.

During 2024, we declared aggregate common share dividends of $4.90 per share, which includes both our annual-variable and quarterly common share dividends of $4.50 per share and $0.10 per share, respectively; repurchased 0.7 million of our outstanding common shares, at an average cost of $201.32 per common share; redeemed all of our outstanding Serial Preferred Shares, Series B, for $500 million in aggregate; and declared and paid aggregate preferred share dividends of $8 million. We ended 2024 with $32.5 billion of total capital and a debt-to-total capital ratio of 21.2%.

Following are a few key performance metrics for 2024:

We encourage you to review our Annual Report to Shareholders for additional information on our 2024 performance and our financial results.

CORPORATE GOVERNANCE HIGHLIGHTS

Corporate Governance Practices

We are committed to meeting high standards of ethical behavior, corporate governance, and business conduct. Some of our corporate governance practices include:

Board Risk Oversight

The Board is ultimately responsible for overseeing our risk profile and risk management processes. To facilitate these responsibilities, the Board assigns certain risk oversight responsibilities to each of its main committees through each committee’s charter. The committees continue to undertake the increasingly detailed oversight work for which they are responsible, to interact with and oversee management, and to report back significant matters to the full Board. A more detailed discussion of this oversight function is contained in the “Board Risk Oversight” section of this Proxy Statement.

SUSTAINABILITY AND ESG HIGHLIGHTS

Sustainability and ESG initiatives have been an integral part of the company’s business. Our Core Values are a cornerstone of our business and, as such, are the tenets of these initiatives and have evolved naturally as we work to not only grow our business, but also to support our customers, community, and employees.

The Board’s Approach

The Board and its committees oversee the assessment and management of various sustainability and ESG matters. In their oversight role, our directors ask questions, probe our thinking, provide strategic input, and give guidance informed by their diverse skills and experiences. The following chart highlights some of our Board’s involvement with these matters.

Our Sustainability Efforts

At Progressive, we aim to take a forward-looking approach to everything we do, from the products we offer to the way we interact with the world around us. We work to drive sustainable change for our shareholders, employees, independent agents, communities, and the millions of customers who trust us to protect what is important to them. As our efforts evolve with the world around us, we expect to adapt our sustainability reporting.

Our most recent Corporate Sustainability Report was prepared with guidance from the Nominating and Governance Committee, our executive leadership, and various subject matter experts. The report was informed by elements from various reporting frameworks, namely the Sustainability Accounting Standards Board (SASB) and the Task Force on Climate-Related Financial Disclosure (TCFD), and includes indices to each of these reporting frameworks. The report provides information regarding our philosophy and practices on a number of topics, including:

To review our most recent Corporate Sustainability Report, including the limited assurance report by an independent third party of our Scope 1 and Scope 2 location-based and market-based greenhouse gas emissions reporting, please visit our sustainability site atprogressive.com/sustainability. The report and any other information on the sustainability site are not incorporated by reference in, and do not form part of, this Proxy Statement or any other SEC filing.

HUMAN CAPITAL MANAGEMENT

We believe that our people and our culture remain our most significant competitive advantage, and that having the right people working together in the right way is critical to driving our results, building our enduring business, and creating long-term shareholder value. Our culture is deeply rooted in our Core Values and is the foundation for our human capital management strategies to attract, hire, engage, and retain highly qualified employees.

Our People

We believe that our culture and continued success has enabled us to create a workplace composed of highly talented people across diverse markets and with a broad range of backgrounds and experiences.

Attract and Hire We employ extensive recruiting practices with a goal of developing qualified and deep candidate pools and attracting candidates from both established and new sources. We believe that our recruitment efforts generally have enabled us to present high-potential pools of job candidates to our hiring managers. In turn, we train our hiring managers to identify and avoid unconscious biases they may have during the interview and selection process and the importance of employing individuals with different kinds of experiences and backgrounds. We believe these strategies collectively enhance our applicant pools and contribute to our continued success.

Engage and Retain We understand that engaged employees are more productive, provide better service to our customers, and are more likely to stay with Progressive. Each year, we survey our people to measure their engagement. We use the results, along with other information, to evaluate our human capital strategies and the health of our culture.

Employee retention is an important part of our strategy. Promoting from within is also a key part of our strategy. Many of our leaders, including most executive team members, joined Progressive in a more junior position and advanced to significant leadership positions within the organization. As of December 31, 2024, we had about 66,300 employees. We disclose our consolidated EEO-1 data on our website.

Supporting our People and Culture

We strive to support our employees by providing challenging work experiences, career opportunities, and a culture of learning. We are focused on coaching and development, which we believe promotes greater engagement in our business and improved individual performance.

Training and Development We actively foster a learning culture and offer several leadership development programs, including a program open to employees of all backgrounds with a focus on leading inclusively. Moreover, our career development resource, “Career Central,” encourages employees to take control of their careers through career exploration guides, recorded career journeys, discovery questionnaires to guide employees to roles that match their skills, and more. Available to new and tenured employees, our learning solutions are tailored to both individual contributors and leaders and cover a broad swath of skills and competencies.

ERGs Over a decade ago, our first Employee Resource Groups (ERG) were created to help build communities for our employees. We believe our ERGs, which are each open to all employees at the company, provide spaces for networking, understanding differences, and sharing experiences. Our first ERGs launched in 2007, and 44% of Progressive people belong to at least one of the following ERGs as of December 31, 2024:

•Asian American Network

•Disabilities Awareness Network

•LGBTQ+ Network

•Military Network

•Network for Empowering Women

•Parent Connection

•Progressive African American Network

•Progressive Latin American Networking Association

•Young Professionals Network

Compensation and Benefits As part of employee compensation, nearly all Progressive people participate in our annual cash incentive program, named Gainshare, which rewards the growth and profitability of our insurance businesses. We believe Gainshare contributes to the cooperative and collaborative way we work together and, in part, defines our culture. We also monitor overall pay equity among employees with similar performance, experience, and job responsibilities, and publish the results annually on our website.

Additionally, our employee benefits are intended to be competitive and to support the needs of our people and their families. We invest in physical, emotional, and financial health of Progressive people by providing a broad range of benefits.

Diversity, Equity, and Inclusion

We believe that in order to be consumers’, agents’, and business owners’ number one destination for insurance and other financial needs, we need to anticipate and understand the needs of our customers. Therefore, we aspire to take full advantage of the rich diversity of our employees’ unique backgrounds, experiences, skills, talents, and perspectives. Our diversity, equity, and inclusion efforts are overseen by our Compensation and Talent Committee on behalf of the entire Board.

For Progressive, our inclusive workplace philosophy is not represented by just a program, initiative, or singular goal. We take a holistic approach guided by four primary objectives, which have been in place for several years:

•to maintain a fair and inclusive work environment;

•to reflect the customers we serve;

•for our leaders to reflect the people they lead; and

•to contribute to our communities.

We challenge ourselves to reach far and wide to attract highly qualified and deep applicant pools when recruiting opportunities arise, and to invest broadly in developing our internal talent.

We’re committed to creating an environment where all our people feel welcomed, valued, and respected, and we integrate this commitment into our workplace. This includes hosting regular IQ Inclusion Quarterly SM events which feature a series of speakers, discussion groups, and storytelling focused on themes such as embracing vulnerability and increasing collaboration.

Moreover, we support efforts to contribute to our communities, through our Keys to Progress® programs (which provide vehicles to veterans and veteran-focused organizations), and by supporting programs which furnish homes for individuals emerging from homelessness, our various education and engagement efforts, and our financial contributions to various community organizations.

For over 20 years, we also have contributed to The Progressive Insurance Foundation (Foundation). Through the Name Your Cause® program, each employee can recommend an eligible charity to receive a fixed

amount of the Foundation’s charitable giving without requiring the employee to make an out-of-pocket donation. This is the Foundation’s way of supporting causes and reaching communities across the country where our people, and our customers, live and work. Since 2020, Progressive has also contributed, either directly or through the Foundation, to national charitable organizations identified by our ERGs.

See “Compensation Discussion and Analysis – Elements of Compensation – The Role of Diversity, Equity, and Inclusion” for more information.

EXECUTIVE COMPENSATION HIGHLIGHTS

We believe that our executive compensation program has been a critical component of our strong operating results and, in turn, shareholder returns in recent years. We generally provide base salary to our executives near or below the market median and provide a significant percentage of total compensation in the form of performance-based equity awards that provide upside potential when we perform well against pre-established and objective measures that we believe correlate to shareholder value. In furtherance of our long-standing goal to grow as fast as we can at a 96 or better combined ratio while continuing to deliver high-quality customer service, we use the combined ratio as a performance measure in several compensation elements.

We believe that the overall structure of our executive compensation program supports a strong pay-for-performance linkage and aligns the interests of our executives with those of our shareholders. For example, during the past five years:

•We grew faster than the markets for the insurance business lines we measure, resulting in the related vesting of the performance-based restricted stock unit awards above target;

•We achieved long-term fixed-income portfolio returns in line with our benchmark group, resulting in the vesting of the performance-based restricted stock unit awards that reflect our investment results near target; and

•Our annual Gainshare program payout has ranged from 86% to 192% of target, with an average of 159% of target, based on the growth in average policies in force and profitability of our insurance businesses (for 2024, it paid out at 178% of target).

Our executive compensation program is overseen by the Compensation and Talent Committee of the Board. The Committee’s decisions are made after considering third-party compensation data for comparable companies, internal analyses, and recommendations presented by management. The executive compensation decisions for executive officers generally represent the culmination of

extensive analysis and discussion, which typically take place over the course of multiple committee meetings and in meetings between the committee and management, including our CEO, our Chief Human Resources Officer, members of our compensation and law departments, and sometimes compensation consultants.

Our executive compensation program has a number of important structural features and guiding policies. Below are the executive compensation practices we follow:

STAKEHOLDER ENGAGEMENT

We seek to provide transparency into our business, our performance, our strategic priorities, our governance practices, and how our Core Values guide our decisions and support our culture. We share information with our stakeholders in a variety of ways, including monthly earnings releases, quarterly investor calls, annual shareholder meetings, quarterly letters from our CEO, and annual letters from our Chairperson of the Board.

We recognize the value in maintaining open lines of communication with our stakeholders and engage with our stakeholders throughout the year to:

•provide visibility and transparency into our business, our performance, and our corporate governance, ESG, and compensation practices;

•discuss with our investors the issues that are important to them, hear their expectations for us, and share our views; and

•assess emerging issues that may affect our business, inform our decision making, and enhance our corporate disclosures.
