LP's Two-Speed Engine: Siding Pulls While OSB Sinks to Negative EBITDA
Unanticipated floods, a bitter OSB trough, and a CFO handoff frame a quarter where LP doubled down on Siding growth and cut $70M of commodity-flavored capex.

The Two-Speed Quarter
Louisiana-Pacific's Q2 2026 report laid out a deliberately split picture: a Siding franchise that keeps compounding share, and an OSB commodity leg priced into a cyclical trough. Net sales of $664M were down $90M year-over-year, and EBITDA fell to $79M from $142M, but the decline was almost entirely a commodity story—Siding sales actually grew 4% with 7% higher prices, even as volumes lapped last year's all-time record quarter. CEO Jason Ringblom set the tone early: “Despite a housing market that feels like it's stuck in neutral, our Siding business delivered revenue above the midpoint of our guided range and achieved year-over-year volume growth in ExpertFinish.” — Jason Ringblom, Chief Executive Officer · 2026-08-05 The most distinctive part of the quarter wasn't the guidance—it was two unanticipated operational events that hit late in the quarter and that management framed as pure timing rather than a break in trend. Alan Haughie, in one of his final calls as CFO, walked through the double impact: “unusually severe flooding ... in Manitoba impacted our team at Swan Valley” — Alan J. Haughie, Chief Financial Officer · 2026-08-05, alongside equipment failures at the Dawson Creek mill and freight-capacity constraints tied to the Iran conflict. His math was explicit: the planned Q1 inventory build that was supposed to cushion Q3's Sagola press outage instead got consumed early, pulling forward absorption effects. Absent these events, LP would have been at or above the top of its guided EBITDA range. Total revenue of $574M in the latest 10-Q (Q1 2026) was down 21% YoY, and the quarter-to-quarter swing in operating income is governed more by Siding mix and OSB prices than any structural change in end demand.OSB at the Cyclical Floor
The OSB guidance is the clearest tell of LP's strategic trajectory. Incoming CFO Aaron Howald put it bluntly:Q3 EBITDA is guided near negative $45M and the full year near negative $120M, with prices down another ~6% since the May call even as input costs rose. LP is managing utilization in the mid-to-high 70s, leaning on the redundancy built into its network so that Structural Solutions isn't sacrificed. The price realization problem is a commodity-wide phenomenon—one that fits a global moment where IEEPA tariff refund mechanics and supply-chain reshuffling are reshaping margins across building products—but LP's answer is decisively to redeploy capital toward the franchise that has pricing power. Capital expenditure of $61M in Q1 was down 5% YoY, and the full-year plan is now $320M, a $70M cut, with roughly three-quarters directed to Siding and essentially all growth capex going to the Specialty side.Unfortunately, the outlook for OSB is moving the opposite direction. The OSB demand environment remains very challenging.
Siding's Long Runway, Distribution's Pivot
The Siding share story remains the centerpiece of the bull case. Ringblom's slide chart is compelling: “Any way you look at it, SmartSide is gaining share and we remain confident that we have a long runway for continued growth ahead of us.” — Jason Ringblom, Chief Executive Officer · 2026-08-05 Over 15 years, SmartSide volume has compounded at nearly 10% annually versus a 6% CAGR for single-family starts; versus the mid-COVID housing peak, starts are down 18% while SmartSide volume is up 10% and revenue up over 50%. The share gains are coming largely from vinyl conversion—a theme Jason flagged even in the prior call: “we are hearing from our customers that there are some manufacturers going up on the vinyl side; that just makes SmartSide more attractive” — Jason Ringblom, Executive/Management · 2026-05-06—and, per the current call, from brick and stucco as builders hunt for affordability. Order intake in Q2 exceeded four of the previous five quarters, and management expects Siding to return to year-over-year volume and revenue growth in Q3. The inventory build and drawdown timing is the connective tissue of the quarter: Q1's planned build supported margins, Q2's unplanned consumption pulled forward the mechanics, and Q3's drawdown should be smaller than expected. Meanwhile, a notable new wrinkle is the distribution transition. Jason Ringblom addressed the Boise Cascade news directly:, targeting committed new partners by October 1 and recalling a 2017 transition at roughly double the scale. This resilience is part of a broader theme—LP's flooding-related freight disruption this quarter was a one-off, but the constrained freight capacity itself is a recurring cost headwind tied to crude and the Iran conflict.For LP, we don't anticipate any lapse in coverage... we have 2 or more distributors that service all of our markets
