Waste Connections 1Q26: Structural Expansion Thesis Behind Revenue Beat and Pricing Upside

Core Conclusions

Waste Connections reported 1Q26 revenue growth of 6.4% to $2.371 billion, beating consensus by 88bps. Core pricing came in at 6.0%, exceeding management's guidance by 20bps. Adjusted EBITDA margin expanded 50bps year-over-year to 32.5%. More critically, full-year core pricing guidance was raised to ~5.5%, the upper end of the range. Current valuation relative to WM and RSG sits at a historical premium discount exceeding two standard deviations, presenting a rare mean-reversion opportunity. Maintain Overweight rating with $205 target price, implying ~10% upside.

What the Market May Be Underestimating

Investors broadly focus on negative volume growth (internal solid waste volumes -1.5% YoY) and the M&A-driven nature of the E&P segment, but overlook three key points: First, core pricing momentum exceeded expectations (6.0% vs. 5.8% expected), with full-year guidance raised to the upper end, and ~75% of price increases already implemented by end-1Q26. Second, margin expansion is accelerating despite 40bps of commodity headwinds and 20bps of fuel cost pressure, with adjusted EBITDA margins still expanding 50bps. Third, the current valuation premium over WM and RSG is at historical extremes (1.1x vs. WM vs. historical average 3.2x; 0.8x vs. RSG vs. historical average 3.4x), offering substantial mean-reversion potential for valuation recovery.

Evidence Chain: Four Structural Drivers

1. Revenue Beat Driven by Dual Engine of Pricing and E&P

Total revenue grew 6.4% YoY. Internal revenue growth of 4.4% exceeded expectations by 90bps. Core pricing of 6.0% beat MSe by 20bps, representing the primary driver of the beat. E&P revenue grew 24% YoY to $179.6 million, exceeding MSe by 20%, but organic growth was only 4%, indicating this segment is M&A-dependent.

Investment Implication: Pricing power persists through a volume downcycle, demonstrating WCN's irreplaceable sticky customer base in the solid waste market.

2. Margin Expansion Achieved Despite Headwinds

Adjusted EBITDA margin expanded 50bps YoY to 32.5%. Positive factors include: 90bps price/cost spread, improved turnover rates, and third-party landfill utilization. Negative factors were 40bps of commodity headwinds and 20bps of fuel costs.

Investment Implication: Margin expansion was achieved amidst four headwinds (commodity prices, fuel costs, declining C&D volumes). If the commodity environment improves or fuel surcharge recovery accelerates, margin upside elasticity is significant.

3. Full-Year Core Pricing Guidance Raised

Core pricing came in at ~6.0%, 20bps above expectations. Management raised full-year pricing guidance to the upper end of ~5.5%. Approximately 75% of price increases were implemented by end-1Q26, with the remainder to be reflected gradually.

Investment Implication: Pricing upside directly enhances internal revenue growth with high visibility. Based on 2026E EBITDA of ~$3.3 billion, every additional 10bps in core pricing corresponds to ~$33 million in EBITDA incremental benefit.

4. Valuation at Extreme Historical Lows

Current valuation is ~15x 2026E EBITDA. Premium over WM is only 1.1x, well below the historical average of 3.2x; premium over RSG is 0.8x, below the historical average of 3.4x. Both metrics are more than two standard deviations below historical averages.

Investment Implication: The valuation discount provides a safety margin for long-term mean reversion. Assuming premium reverts to half the historical average (~2x), the implied EV/EBITDA would be ~16x, with an implied stock price around $220.

Key Disagreements and Risks

1. Persistent Volume Weakness

C&D volumes declined 5% for the tenth consecutive quarter. If macroeconomic weakness deepens, internal solid waste volumes could remain negative in 2026E (model forecasts -1.3%), dragging total revenue growth to 5.2%.

2. Asymmetric Commodity and Fuel Cost Risks

Recycling revenue prices improved to $89/ton in 1Q26 ($94/ton at quarter-end), but historical volatility is high. Diesel is only 45% hedged, with the remainder dependent on surcharge recovery. If oil prices continue rising while surcharges lag, cost pressures may expand in the near term.

3. E&P Segment Growth Dependent on M&A

E&P revenue grew 24% total, but only 4% organically. 2026E segment growth is expected to decelerate to 11.1%. If shale oil activity or waste fluid treatment demand contracts rapidly, growth could fall short.

4. Financial Model Risk

DCF valuation is based on WACC of 6.3% and terminal growth rate of 2.8%. Every 25bps change in terminal growth rate implies a ~$25 stock price swing. If the current assumption of 34.0% 3Q26E EBITDA margin is not realized, margin expansion will slow.

Valuation or Trading Implications

Current stock price implies 15x 2026E EBITDA, with a $205 target price corresponding to ~16x. Upside pathway driven by: pricing upside driving internal revenue outperformance (+$2/share), valuation reverting to half the historical average premium (+$15/share), and commodity recycling improvement or E&P revenue upside (+$5/share). Key catalysts: fuel surcharges beginning to reflect oil price increases in Q2, and Q2 pricing data validating full-year guidance realization. Downside risks primarily from macroeconomic deterioration impacting volumes and acquisition performance.
