### Deep Research Update: Avis Budget Group (CAR) **Status:** Thesis Validation & Risk Assessment **Date:** May 20, 2024 --- #### 1. Validation of Thesis **Thesis:** *Heavy insider buying via synthetic longs and high short interest suggest a short squeeze/capital cycle turn.* * **Status:** **Partially Valid / Weakened.** * **Insider Activity:** While historically significant (notably the heavy accumulation by SRS Investment Management, which controls ~30%+ of the company), recent filings show a stabilization rather than an aggressive new wave of buying. The "synthetic long" narrative (equity swaps/derivatives) remains a structural feature of their capital allocation, but it is now well-understood by the market rather than a hidden catalyst. * **Short Interest:** CAR remains one of the most heavily shorted stocks in the mid-cap space (Short Interest as % of Float consistently stays in the 25–35% range). While this provides the "fuel" for a squeeze, the high borrow cost has led to a persistent "grind down" rather than a volatility-driven squeeze, as the market increasingly focuses on fundamentals over technicals. #### 2. Counter-Thesis (Risks) * **Depreciation Headwinds:** The primary risk is the normalization of vehicle residual values. CAR’s profitability in 2021–2023 was driven by an unprecedented bubble in used car prices. As used car prices decline, per-unit depreciation costs are rising, compressing EBITDA margins significantly. * **High Interest Rate Environment:** CAR is a capital-intensive business reliant on Asset-Backed Securities (ABS) and corporate debt to fund its fleet. The "higher for longer" interest rate environment increases interest expense, cannibalizing free cash flow (FCF). * **Fleet Utilization vs. Travel Demand:** Recent industry data indicates a plateauing of leisure travel pricing power. If the "revenge travel" tailwind fades, CAR’s fleet utilization rates face downward pressure, forcing them to hold idle assets that depreciate rapidly. #### 3. Recent SEC Filings & Significant Events * **Q1 2024 Earnings (May 2024):** Reported revenue of $2.6 billion, a slight decline year-over-year. The key takeaway was the **increased per-unit fleet cost**, confirming that the normalization of vehicle values is impacting the bottom line faster than anticipated. * **Share Repurchase Program:** CAR continues to be a massive repurchaser of its own shares. SEC filings confirm they are aggressively utilizing their liquidity to retire float. This supports the thesis that management (and major holders) believe the stock is undervalued, providing a "soft floor" for the share price. * **Debt Refinancing:** Recent 8-K filings highlight continued activity in the ABS market. Investors should monitor the *yield* on these notes; any significant spike in the cost of debt will be a leading indicator of margin contraction. --- ### Analytical Conclusion The **Short Squeeze thesis is currently dormant**. The market is currently valuing CAR based on its **transition from a "hyper-growth/windfall" post-pandemic company to a "cyclical utility."** * **Bull Case:** Continued aggressive share buybacks, combined with an unexpected uptick in business travel demand, could force a short covering rally. * **Bear Case:** The structural increase in fleet depreciation costs continues to outpace pricing gains, leading to a downward revision of earnings expectations. **Research Note:** The "Capital Cycle" turn is currently working against the company, not for it. Unless there is a catalyst for higher rental rates, the stock will likely remain range-bound, tethered to the rate of fleet depreciation.

Detailed Deep Dive

Recently, Pentwater has been aggressively buying Avis (CAR). But it’s not the buying itself that’s interesting; it’s how they’re doing it. Consider this form 4.

CAR’s stock has been trading for ~$95/share for most of this month. For some reason, Pentwater has decided a synthetic long (buying a call and selling a put at the same strike) is a better way to increase exposure than simply buying the stock. I’m sure Pentwater is a lot smarter than me and there’s a reason they chose that specific structure to increase their exposure to the stock…. but I’d be remiss if I didn’t note that CAR is a very tightly held stock as SRS and Pentwater now hold >60% of the stock between them.

Bloomberg tells me almost 50% of CAR’s free float is sold short; could Pentwater’s synthetic long create some fireworks (read: short squeeze) once they take delivery? And, on a fundamental level, it’s been a rough few years for rental cars…. is Pentwater seeing something in the data that suggests the capital cycle is about to turn? The combo of tightly held + lots of short interest + trough-ish cycle + a history of aggressive capital return from CAR could cause things to get spicy very quickly….
