As of Sep 14, 3:10 PM EDT, market action underlined growing divergence in the pet retail space. Chewy Inc (CHWY) climbed +6.29% to $21.73 while Petco (WOOF) inched up just +0.61% to $2.465. The two stocks have moved differently over multiple time frames, reflecting deeper contrasts in revenue trends, profitability and capital structure.
Price performance and what it signals
Year-to-date, Chewy is down 34.1% while Petco is down 12.3%. Over the last 12 months Chewy has fallen 37.3% versus Petco’s 28.8% decline. Those different magnitudes of drawdown help explain the pairs-trade tension between a digital-native operator and a leveraged legacy retailer.
Valuation scorecard
The relative valuation picture is mixed depending on the metric. Key figures are presented below.
| Petco (WOOF) | Chewy Inc (CHWY) | Edge | |
|---|---|---|---|
| Market Cap | $701.7M | $8.22B | - |
| P/E (LTM) | 23.3x | 31.9x | WOOF cheaper |
| EV/EBITDA | 9.7x | 21.5x | WOOF cheaper |
| Price/Book | 0.6x | 23.6x | WOOF cheaper |
| FCF Yield | 33.7% | 6.5% | WOOF higher |
| ROE | 2.6% | 72.0% | CHWY dominant |
| ROA | 0.6% | 8.0% | CHWY dominant |
| Rev Growth | -1.3% | +5.9% | CHWY growing |

Note: WOOF’s 33.7% free cash flow yield is a central caveat in interpreting these numbers - more on that below. Screener values are snapshots and may lag live prices slightly.
Revenue and operating momentum
The revenue paths tell much of the story. Petco peaked at $6.26B in FY2024 and has slid to $5.96B in FY2026. Chewy by contrast has compounded revenue from $8.97B to $12.60B over the same period, a cumulative gain of 41% driven in part by its autoship subscription model.
Operating profits show a similar divergence. Chewy’s EBITDA rose from a near-zero $55.9M to $341.9M in two fiscal years, an approximately $286M improvement that reflects operating leverage. In bull-case rhetoric its EBITDA trajectory is summarized as $55M -> $189M -> $342M across the fiscal steps cited.
The FCF trap - why WOOF’s headline yield misleads
Petco’s 33.7% free cash flow yield appears striking at face value but is misleading once the capital structure is considered. Petco carries $2.89B of total debt on a market capitalization of $701M, producing net debt roughly four times the equity value. That cash flow is largely pre-committed to servicing debt rather than available for distribution to shareholders.
Additional balance-sheet signals include a debt-to-equity ratio of 247.9% and a current ratio below 1.0x (0.9x), pointing to liquidity pressure. Petco’s net income margin has just turned positive to +0.2%, which is a marginal improvement but still narrowly positive. In short, the free-cash-flow metric is not a clean indicator of shareholder value for WOOF given the leverage profile.
Pairs trade mechanics and the current setup
The archetypal pairs trade is long Chewy and short Petco - a bet that the digital-native operator outcompetes the leveraged brick-and-mortar incumbent. That positioning has been painful year-to-date as Petco has outperformed Chewy by roughly 22 percentage points.
At current prices the CHWY/WOOF ratio is about 8.8x ($21.73 / $2.465), narrower than prior peaks because Chewy has fallen more on macro concerns.
Bull case for re-entering long CHWY / short WOOF
- Chewy’s EBITDA path (reported transitions from about $55M to $189M to $342M) represents clear earnings momentum in the sector.
- TD Cowen named Chewy its best small/mid-cap idea for 2026, assigning a $34 target (TD Cowen, Jun 23, 2026).
- Piper Sandler (Overweight, $30 PT) flagged web traffic acceleration and share gains in August (Aug 21, 2026).
- Fair value upside estimates favor Chewy: +35.6% to a $29.46 fair value versus Petco’s +25.9% to a $3.10 fair value.
- Today’s share move - Chewy +6.29% vs Petco +0.61% - may indicate the ratio is beginning to re-widen in favor of the long CHWY leg.
Bear case and key risks
- Petco’s micro-cap status at $701M makes a short position on WOOF vulnerable to structural short squeezes.
- If Petco can successfully reduce debt and expand gross margins - currently noted at 38.7% and described as best-in-class - the stock could re-rate higher.
- Macro pressures like softer pet ownership trends and channel migration to large omnichannel retailers are risks that affect both names, and the sector broadly.
Conclusion
On raw valuation multiples - P/B, EV/EBITDA and free cash flow yield - Petco appears cheaper. However that apparent cheapness is largely a function of leverage and liquidity stress rather than a clean value opportunity. When adjusting for quality attributes - fair value upside, return on equity, return on assets, revenue growth and analyst conviction - Chewy presents a stronger case.
The classic long CHWY / short WOOF trade looks attractive at current ratio levels given Chewy’s EBITDA inflection, but traders should size the short leg conservatively because of Petco’s volatility (beta 1.53) and the possibility of squeeze events.
