Actual results may differ. See “Forward-Looking Statements.”

NYSE SAH Strategic Focus – Franchised Dealerships Segment (continued) 7 Fixed Operations And F&I • Target increasing technician headcount by 300 in FY 2024, projected to generate approximately $100M in incremental annualized fixed operations gross profit (headcount increased by 216 technicians year-to-date) • Fixed operations parts and labor cost inflation is generally passed along to customers, supporting stable fixed operations profit margins over time • Vehicle affordability challenges may drive consumers to choose to repair their current vehicle to extend its life rather than replace it with a newer vehicle, benefitting fixed operations revenues • F&I gross profit per unit increased nearly 50% from FY 2019 to FY 2023, driven primarily by higher warranty contract penetration rates • We believe F&I GPU will remain structurally higher than pre- pandemic • Even in an elevated interest rate environment, finance contract penetration rates remain robust and are supported by manufacturer financing or lease incentives only available at franchised dealerships $1,620 $1,846 $2,160 $2,453 $2,403 $2,403 $2,340 77.4% 77.9% 77.6% 72.9% 71.2% 72.2% 72.9% 38.4% 40.9% 44.4% 49.4% 48.9% 50.8% 48.2% FY 2019 FY 2020 FY 2021 FY 2022 FY 2023 Q3 2023 Q3 2024 F&I Gross Profit Per Unit and Product Penetration Rates F&I GPU Finance Contract Penetration Rate Warranty Penetration Rate $669 $595 $673 $787 $853 $215 $231 49.0% 49.8% 50.2% 49.5% 49.7% 49.8% 50.3% FY 2019 FY 2020 FY 2021 FY 2022 FY 2023 Q3 2023 Q3 2024 Fixed Operations Gross Profit and Gross Margin % Fixed Operations Gross Profit (Millions) Fixed Operations Gross Margin % Note: Technician headcount, fixed operations profit margin and F&I GPU are estimates of future results. Actual results may differ. See “Forward-Looking Statements.”

NYSE SAH Strategic Focus – Franchised Dealerships Segment (continued) Hybrid vs. Electric Vehicle Trends • Industry sales volume penetration rates for combined hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) are nearly double the penetration rates for battery electric vehicles (BEV) and are trending upward • We believe there is an easier path to consumer adoption of alternative power trains as more manufacturers expand their hybrid vehicle model offerings • Hybrid new vehicle GPU was higher than internal combustion engine (ICE) new vehicle GPU in our import and domestic brands, and marginally lower in our luxury brands • BEV new vehicle GPU lags both hybrid and ICE vehicles, resulting in BEV sales negatively impacting total new vehicle GPU by approximately $440 in Q3 2024 (compared to $170 negative impact in Q2 2024 and a $400 negative impact in Q1 2024) • Initial BEV repair and maintenance trends show lower frequency but higher gross profit per repair order vs. ICE vehicles, while hybrid vehicles create opportunity to service both types of power trains • Ongoing investment in BEV repair and maintenance capabilities (e.g. heavy-duty vehicle lifts, battery removal and storage needs, technician training) • Over 90% of Sonic’s franchised dealerships are equipped with electric vehicle charging capabilities 16.5% 8.6% 0% 4% 8% 12% 16% 20% Fe b- 19 M ay -1 9 Au g- 19 N ov -1 9 Fe b- 20 M ay -2 0 Au g- 20 N ov -2 0 Fe b- 21 M ay -2 1 Au g- 21 N ov -2 1 Fe b- 22 M ay -2 2 Au g- 22 N ov -2 2 Fe b- 23 M ay -2 3 Au g- 23 N ov -2 3 Fe b- 24 M ay -2 4 Au g- 24 Hybrid Vehicle vs. EV Industry Sales Volume Penetration Hybrid (HEV/PHEV) Penetration % BEV Penetration % So ur ce : M or ga n St an le y R es ea rc h 8 100% Luxury Import Domestic Total Sonic Q3 2024 Average New Vehicle Relative GPU by Power Train BEV Hybrid ICE Average New Vehicle GPU Note: Average new vehicle relative GPU by power train in the chart above is shown as a percentage of blended average GPU for each brand group and franchised dealerships segment total GPU, where 100% represents the blended average GPU for each brand group and the franchised dealerships segment total GPU.

NYSE SAH Strategic Focus – EchoPark Segment • Returned to positive segment adjusted EBITDA* beginning in Q1 2024 after 3 years of industry-driven headwinds • Focus on leveraging retail sales volume momentum and improving used market backdrop to maintain positive adjusted EBITDA* and drive significant year-over- year adjusted EBITDA* growth in FY 2024 • Expect to resume disciplined expansion of EchoPark footprint once used vehicle market conditions are supportive • Long-term goal to reach 90% of the U.S. population • Below-market pricing and no-haggle, transparent guest experience expected to drive market share gains EchoPark Strategy * Refer to appendix for calculation and reconciliation of Adjusted EBITDA (a non-GAAP measure). Note: Adjusted EBITDA and footprint expansion projections are estimates of future results. Actual results may differ. See “Forward-Looking Statements.” Financial data may also include certain forward-looking information that is not presented in accordance with GAAP. We believe that a quantitative reconciliation of such forward-looking information to the most directly comparable GAAP financial measure cannot be made available without unreasonable efforts, because a reconciliation of these non-GAAP financial measures would require an estimate of future non-operating items such as impairment charges or gain/loss on property dispositions. Neither the timing nor likelihood of these events, nor their probable significance, can be quantified with a reasonable degree of accuracy. Accordingly, a reconciliation of such forward-looking information to the most directly comparable GAAP financial measure is not provided.

NYSE SAH Strategic Focus – EchoPark Segment (continued) 10 • Anticipate positive retail used vehicle GPU throughout FY 2024 due to faster inventory turns and stability in wholesale and retail prices and used car supply • Maintain focus on optimizing F&I product offerings and pricing to drive F&I GPU growth in FY 2024 • Expect used vehicle wholesale and retail prices to continue to gradually decline throughout FY 2024, reducing inventory acquisition costs and potentially driving incremental industry sales volume as consumer affordability improves • Used vehicle supply is projected to reach its lowest point in 2025, due to lower levels of off-lease inventory as a result of declines in new vehicle industry sales volume since 2020 and fewer lease originations, however, off-rental supply is improving which may provide an alternate source of inventory to mitigate the impact of fewer lease maturities • Beyond 2025, gradual expansion of used vehicle supply and further normalization of used vehicle pricing should drive consumer demand and higher retail sales volume for EchoPark EchoPark Strategy $20.7 $10.7 $(47.8) $(105.4) $(83.0) $(5.2) $8.9 $2,296 $2,013 $1,762 $2,657 $2,183 $2,767 $3,111 FY 2019 FY 2020 FY 2021 FY 2022 FY 2023 Q3 2023 Q3 2024 EchoPark Segment Adjusted EBITDA* and Total GPU (Used GPU + F&I GPU) Adjusted EBITDA* (Millions) Total GPU Source: J.D.

NYSE SAH Sonic Automotive FY 2024 Outlook • Expect low single digit percentage growth in revenues and mid single digit percentage decline in gross profit, driven by: • Continued normalization of new vehicle GPU, potentially exiting 2024 in the $3,000 per unit range, with >60 days’ supply by Q4 2024 • Low single digit percentage growth in new and used retail sales volume, consistent with industry SAAR • Mid single digit percentage growth in fixed operations gross profit • Low single digit percentage F&I gross profit growth, driven by higher retail unit volume and F&I GPU near $2,400 per unit • Expect adjusted SG&A expenses as a % of gross profit* in low 70% range Consolidated • Expect lower Franchised Dealerships Segment earnings to be partially offset by higher earnings in our EchoPark and Powersports Segments • Expect $15-20 million increase in annual floor plan interest expense due to higher new inventory levels and higher average interest rates vs. FY 2023 • Earnings per share results for FY 2024 are primarily dependent upon rate of normalization of new vehicle GPU and rate of EchoPark profitability improvement Franchised Dealerships Segment EchoPark Segment • Achieved positive adjusted EBITDA* of $7.3 million in Q1 2024, $7.2 million in Q2 2024, and $8.9 million in Q3 2024, and expect Q4 2024 adjusted EBITDA* between $7-$8 million, driven by: • Organic volume growth opportunities at existing store footprint, driven by higher unit volume throughput per store and positive used vehicle GPU • Expect low double digit percentage F&I GPU growth year-over-year • Expect SG&A expenses as a % of gross profit in the high 70% range (target below 70% at maturity) Powersports Segment • Expect FY 2024 adjusted EBITDA* between $6-$7 million, with majority coming in Q3 (Q1 & Q4 near breakeven due to seasonality) * Refer to appendix for calculation and reconciliation of Adjusted EBITDA (a non-GAAP measure).
