GFL Environmental heads into its third-quarter report with an unusual combination working in its favor: a guidance outlook that has climbed on every call this year, and a board fielding unsolicited take-private approaches at prices said to be well above where the stock traded. That pairing raises the stakes. Management has told the market its business has never been in better shape, and outside buyers appear to agree. Now the quarter has to show that pricing and margin gains can keep outrunning soft volumes, high diesel costs and a weak Canadian dollar.

Wall Street is looking for earnings of $0.20 a share on revenue of about $1.49 billion when results arrive after the close on October 28. That implies roughly 18% growth in earnings and 21% growth in revenue from a year ago, a strong pace for a waste hauler, though a large slice of the revenue gain reflects acquisitions rather than organic expansion. GFL closed seven deals in the second quarter alone, including the Frontier business in Texas, so this is the first full quarter in which those purchases should flow through. Sequentially, the Street expects a solid step up from the second quarter's $0.14 and $1.41 billion, consistent with the seasonal strength of summer collection and disposal activity.

The full-year framework gives the consensus some cover. After two raises, management is guiding to about $7.52 billion in revenue, $2.29 billion in adjusted EBITDA, $900 million in free cash flow and a 30.5% EBITDA margin, all backed by pricing now running just above 6%, roughly half a point better than the original plan. The key is the margin story. Underlying margin expansion has been tracking at about twice the initial target, Canada posted a record 34% margin, and cost intensity has fallen for six straight quarters. A third-quarter margin that holds near or above 30%, while absorbing the fuel surcharge lag tied to a roughly 60% jump in diesel prices, would confirm that the improvement is structural rather than a lucky stretch.

Volume is the soft spot to scrutinize. Management cut its full-year volume outlook to about a half-point decline after construction and demolition and special waste landfill tons fell around 10% to 11% in the second quarter. If those streams stabilize, the reduced volume assumption starts to look conservative. If they weaken further, it would raise questions about how much longer price alone can carry organic growth. Leverage matters too. Net leverage rose to 3.9 times on acquisitions and currency translation, and management expects it back in the mid-3s by year-end, so investors should look for visible progress toward that goal.

The forward catalysts may overshadow the quarter itself. The Secure acquisition was expected to close at the start of the fourth quarter and could add roughly 6% to 2026 EBITDA, pushing growth above 20%, yet none of it sits in current guidance. Any update on the timing, the folding of Secure into the outlook, and the status of the special committee's review of buyout interest could move the stock as much as the reported numbers.

Sentiment has warmed but remains cautious, with the bearish reading easing to about 22% from 35% ahead of the last report. The shares have gained 6.5% since then, edging past the S&P 500, and at $44.68 sit right at their post-earnings high, well above the 200-day average near $40.70 and above the prior quarter's ceiling of $42. That puts the stock on the verge of a breakout, which raises the bar. The narrative stays intact if GFL keeps its margin trajectory on track and at least reaffirms its raised outlook despite fuel and volume drag. A slip in margins or a softer free cash flow view would suggest the cyclical headwinds are finally catching up with the pricing engine.
