KEMPER TO ACQUIRE INFINITY IN $1.4 BILLION TRANSACTION

Establishes Leading Provider of Nonstandard Auto Insurance with Scale and Focus to Deliver Differentiated Product Offerings

Transaction Creates Attractive Returns for Shareholders Through Meaningful EPS, ROACE and ROATCE Accretion

CHICAGO, IL and BIRMINGHAM, AL., Feb. 13, 2018 – Kemper Corporation (NYSE: KMPR) and Infinity Property and Casualty Corporation (NASDAQ: IPCC) today announced that they have entered into a definitive merger agreement under which Kemper will acquire Infinity in a cash and stock transaction valued at approximately $1.4 billion, or $129.00 per share; the exchange ratio for stock consideration to be issued in the merger is fixed and was determined based on Kemper’s 20-trading day volume weighted average price as of February 12, 2018 of $64.40. Based on Kemper’s February 12, 2018 closing stock price of $57.75, the implied total consideration is approximately $1.3 billion, or $121.01 per Infinity share. The transaction creates a company with increased scale in nonstandard auto insurance and enhanced ability to serve policyholders.

Infinity is a provider of auto insurance focused on serving the specialty, nonstandard segment. With approximately 2,300 employees, 10,600 independent agents and $1.4 billion in 2017 direct written premiums, Infinity is one of the largest nonstandard auto insurers in the country.

“This compelling transaction combines two well-known brands with complementary strengths and cultures to form a leader in nonstandard auto insurance, and enhances Kemper’s overall growth opportunities, diversification, financial strength, and ability to serve policyholders,” said Joseph P. Lacher, Jr., Kemper’s President and Chief Executive Officer. “We look forward to welcoming the Infinity team to the Kemper family and working together to deliver greater choice to our policyholders through an expanded product offering and deeper relationships with our agent networks, while generating strong returns for our shareholders.”

Glen N. Godwin, Infinity Chief Executive Officer, added, “Together, our two companies have a terrific strategic and cultural fit. As part of a larger company, Infinity will have access to the capabilities and resources necessary to drive accelerated growth and better serve our policyholders and partner agents. In addition, Infinity shareholders will benefit from immediate and certain value for their shares as well as the opportunity to participate in the significant upside potential of the combined company.”

Compelling Strategic and Financial Benefits

Increased Scale:

• Combined company will have a more diversified portfolio with approximately $2.2 billion in nonstandard auto insurance premiums, an expanded customer reach through deeper agency relationships and greater efficiencies.

Broader Product Offering and Capabilities:

• Ability to leverage unique operational strengths, platforms, analytical capabilities and demographic insights to provide a unique set of products to our policyholders, while promoting growth of our business.

• More diversified suite of products across auto, home, life, and health insurance provides customers with greater choice at more competitive prices.

Enhanced Financial Position:

• The transaction is expected to be accretive to Kemper’s EPS in the first year, excluding Value of Business Acquired (“VOBA”) and one-time items, and is expected to be accretive to year two EPS by more than 10%, excluding restructuring and one-time items. Additionally, we expect the transaction to be accretive to return on average common equity (“ROACE”) by more than 30bps and accretive to return on average tangible common equity (“ROATCE”) by more than 400bps in year two following close.

• More balanced revenue mix and enhanced cash flow increases financial stability and provides additional resources to accelerate investments in growth.

• Expected to result in annual cost savings of approximately $55 million and $5 to $10 million of after-tax earnings resulting from the repositioning of Infinity’s investment portfolio to be fully phased in by the end of the second year following close. These cost savings are expected to be achieved through the consolidation of redundant corporate functions and the optimization of the combined company’s systems, business processes and reinsurance programs.

Transaction Details

Under the terms of the definitive merger agreement, Infinity shareholders will receive $51.60 in cash and 1.2019 Kemper common shares for each share of Infinity common stock. The transaction was valued at approximately $1.4 billion, or $129.00 per Infinity share; the exchange ratio for stock consideration to be issued in the merger is fixed and was determined based on Kemper’s 20-trading day volume weighted average price as of February 12, 2018 of $64.40. This represents an approximately 33% premium to Infinity’s closing price of $97.05 as of February 12, 2018. Based on Kemper’s February 12, 2018 closing stock price of $57.75, the implied total consideration is approximately $1.3 billion, or $121.01 per Infinity share, an approximately 25% premium to Infinity’s closing price of $97.05 as of February 12, 2018. The agreement also contains an election procedure allowing each Infinity shareholder to seek all cash or all stock, subject to proration and adjustment. Following the close of the transaction, Infinity shareholders are expected to own approximately 20% of the combined company on a pro forma basis.

Kemper expects to fund the cash portion of the consideration with a combination of cash on hand from the combined companies and other internal resources. No additional financing resources are needed to consummate the transaction, although Kemper may explore issuing an institutional term loan prior to close of the transaction in order to optimize its liquidity position.

The transaction is expected to close in the third quarter of 2018, subject to the satisfaction or waiver of applicable closing conditions, including the approval of shareholders of both companies and receipt of required regulatory clearances and approvals.

Organizational Structure

Upon completion of the transaction, Infinity’s senior management team will be integrated into the newly-combined organization. Additionally, at closing, Kemper will increase its current Board of Directors by one seat and select a Director from Infinity to join the Kemper Board of Directors.
