Pay vs Performance Disclosure

Pay vs Performance Disclosure, Table

Pay Versus Performance. The SEC requires us to present the following disclosures of our “pay versus performance”. These disclosures are intended to show the relationship of the compensation we paid to certain of our executives compared to our financial performance over the past four years. Below you will find: (1) a table with four years of information on compensation “actually paid” to the Principal Executive Officer (“PEO”), which is our CEO, and our other NEOs for the applicable years on average as a group, as well as Total Shareholder Return (“TSR”), net income and EBITDA as adjusted if applicable, as described below; (2) disclosures explaining the relationship between compensation “actually paid” and the performance measures disclosed in the Pay versus Performance Table; and (3) a tabular list of financial performance measures we use to link compensation “actually paid” to NEOs for the last fiscal year to our performance. Our Company produced record earnings in the past four years which resulted in a substantial increase in our stock price. The SEC’s definition of compensation “actually paid” includes the increase in value of unvested restricted stock held by our NEOs which vest over four years with 70% of any award vesting in the third and fourth years. As a result, compensation “actually paid” pursuant to the SEC’s definition of that term has increased significantly over that time as a result of appreciation in the value of unvested restricted stock. Our NEOs may or may not receive the full economic benefit of the compensation showed as “actually paid” depending on the stock price at the time of vest of the restricted stock despite the characterization of such compensation being “actually paid” pursuant to SEC rules.

By SEC rules, these amounts reflect the amount disclosed in our Summary Compensation Table (SCT) for the applicable year (a) minus the grant date fair value of equity compensation in the SCT, (b) plus year-end fair value of stock awards granted in the year that were outstanding and unvested as of the end of year, (c) plus the change as of year-end in fair value of prior year awards that were outstanding and unvested as of the end of year or, for awards vesting in that year, the change in fair value of those awards as of the vesting date. The other elements required to be disclosed pursuant to SEC rules in the definition of compensation “actually paid” are inapplicable to our NEO compensation. The calculations for (b) and (c) are as follows:

The PEO whose compensation is represented in each year is Mr. Penske. Messrs. Denker, Kurnick and Spradlin are included in the NEO averages for each year. Also included in the NEO average in 2020 was J.D. Carlson, our former CFO, in 2021 both Mr. Carlson and Ms. Hulgrave, and, for 2022 and 2023, Ms. Hulgrave.

Total shareholder return measures the change in value of our common stock, adjusted to include dividends received by our shareholders over the period. Our peer group for purposes of the peer group total shareholder return disclosure is the same as the one identified in Item 5 of our annual report on Form 10-K and consists of the following companies, each of which principally conducts automotive retail operations: Asbury Automotive Group, Inc., AutoNation, Inc., Group 1 Automotive, Inc., Lithia Motors, Inc., and Sonic Automotive, Inc. (the “Peer Group”).

Compensation Actually Paid vs. Total Shareholder Return

The following tables show the relationship between (1) compensation “actually paid” to our CEO and the other NEOs to (2) each of total shareholder return, net income and EBITDA as adjusted if applicable. We produced record earnings for our Company in the past four years as net income and Adjusted EBITDA have increased 143% and 105%, respectively over the four year period. Compensation “actually paid” has increased over that time as well, most significantly due to the increase in value of the NEOs’ restricted stock holdings, which vest over four years with 70% of any award vesting in the third and fourth years. Our stock price has increased from $50.22 on December 31, 2019 to $160.51 on December 29, 2023, representing an increase in shareholder value based on our December 29, 2023 outstanding shares of over $7 billion. Excluding the increase in the value of unvested restricted stock, compensation “actually paid” for our CEO, and the other NEOs (consisting of salary, bonus, other compensation and the vesting of restricted stock) increased 214%, and 100%, respectively, over the four year period, as compared to an increase of total shareholder return of 244%.

As noted in the table above, our total shareholder return over the four years increased 244% as compared to a 153% increase by our Peer Group.

As noted in the table above, our total shareholder return over the four years increased 244% as compared to a 153% increase by our Peer Group.

Tabular List, Table

We are required under SEC rules to also disclose the most important financial performance measures that link compensation “actually paid” to our NEOs (which amounts are shown in the table above using the SEC’s methodology) to Company performance. We believe those metrics are as follows:

	Financial Performance Measures
	Net Income
	Adjusted EBITDA
	Earnings Per Share
	Stock Price Performance

We selected these measures because we believe our compensation “actually paid” is most influenced by two factors: (1) the amount of restricted stock granted to our NEOs under the annual performance plans over the relevant period and (2) the change in our stock price over time (see footnote 1 to the Pay Verses Performance Table above). Our 2023 performance plans include metrics for EBITDA, EPS, and stock price performance, which collectively could represent more than 50% of the total amount available under the plans. We believe the change in our stock price over time is correlated most closely to the financial performance measures EBITDA (as adjusted if applicable), EPS (as adjusted if applicable) and net income.
