Brian Biros's questions to HNI (HNI) leadership

Question · Q3 2025

Brian Biros, on behalf of Steven Ramsey, asked for details on the residential building products segment, specifically why orders grew 2% and what drove the acceleration towards the end of the quarter, given flat sales. He also sought to understand the opportunity set in the workplace segment, differentiating between return-to-office trends and non-office verticals.

Answer

Vincent Paul, EVP and CFO, clarified that residential orders were up 2% for the segment, with remodel retrofit orders accelerating to 7% growth and driving a 13% backlog increase, supported by a strong retail season. He noted expectations for unit volume growth in Q4 and for the full year. Jeff Lorenger, Chairman, President and CEO, stated it's difficult to parse the exact split but observed that non-office verticals like education and healthcare have been consistently strong, while return-to-office trends are still in their earlier stages of development.

Question · Q3 2025

Brian Biros of Thompson Research Group asked for details on the 2% growth in residential building products orders, specifically what factors drove this increase and the acceleration observed towards the end of the quarter. He also inquired about the opportunity set within the workplace segment, seeking to understand the relative contributions of return-to-office trends versus non-office verticals.

Answer

Vincent Paul, Executive Vice President and CFO, explained that residential orders were up 2% overall, with remodel retrofit orders increasing by 7% and accelerating, resulting in a 13% backlog growth. This performance, supported by strong retail and other initiatives, is expected to drive high single-digit revenue growth for the quarter and unit volume growth for the full year. Jeff Lorenger, Chairman, President and CEO, noted that while it's difficult to precisely separate, both return-to-office and non-office verticals contribute to the workplace segment's opportunities. He highlighted that verticals like education and healthcare have been robust, while return-to-office trends are still in their early stages but showing increasing momentum.

Brian Biros's questions to ARMSTRONG WORLD INDUSTRIES (AWI) leadership

Question · Q3 2025

Brian Biros asked for a comparison of the current market outlook (stabilizing conditions) to the expectations three months prior (slightly softer second half due to uncertainty and discretionary commercial work slowdown), and what factors are driving this positive shift. He also requested more context on the strong Mineral Fiber margins, specifically the 44% in Q3 and 43% full-year outlook, considering current volume levels and historical comparisons.

Answer

CEO Vic Grizzle explained that the anticipated slowdown in discretionary renovation activity did not materialize as economic activity was revised upward. He noted that growth initiatives significantly contributed to volume, and the company now expects stabilized, flattish market conditions to continue. Mr. Grizzle highlighted the strong Mineral Fiber EBITDA margin (44% in Q3, 43% full-year outlook) as a return to pre-pandemic highs, driven by effective price realization, a richer product mix, and consistent productivity gains. CFO Chris Calzaretta added that contributions from the WAVE joint venture also supported the strong EBITDA margin.

Question · Q3 2025

Brian Biros asked for a comparison of the current outlook of "stabilizing markets" to the previous expectation of a "slightly softer second half," seeking clarification on what is driving this positive shift from uncertainty to stability. He also requested more context on the strong Mineral Fiber EBITDA margins, comparing them to historical performance given current volume levels.

Answer

CEO Vic Grizzle explained that the anticipated slowdown in discretionary renovation activity did not occur due to upward revisions in economic activity, allowing growth initiatives to shine in a flattish market. He highlighted the strong 44% Mineral Fiber EBITDA margin, noting the full-year expectation of 43% would be the highest since 2019, driven by price realization, richer mix, and productivity. CFO Chris Calzaretta added the contribution from WAVE equity earnings.

Question · Q2 2025

Brian Biros sought to confirm that the raised full-year guidance was primarily driven by strong Q2 performance and company-specific initiatives rather than an improved market outlook. He also asked for a more detailed breakdown of the drivers behind the strong Mineral Fiber margins and their sustainability.

Answer

CEO Vic Grizzle confirmed the guidance rationale was correct. CFO Chris Calzaretta detailed that Mineral Fiber margin strength came from strong execution, disciplined cost control, favorable volume, and strong equity earnings from the WAVE joint venture. He noted that for the full year, AUV is expected to grow over 6%, offsetting a flat to low-single-digit decline in volume.

Question · Q1 2025

Brian Biros from Thomson Research Group questioned the rationale for raising the Architectural Specialties sales guidance amid market uncertainty. He also asked if the anticipated pullback in Mineral Fiber volume would be broad-based or concentrated in specific verticals.

Answer

CFO Christopher Calzaretta cited better visibility from project backlogs and longer lead times as the reason for the AS guidance raise. CEO Victor Grizzle added that AS growth is also driven by market penetration, which can continue even if the overall market softens. Regarding Mineral Fiber, Grizzle stated the expected softness is in discretionary renovation work, which he described as 'vertical agnostic' and not tied to any specific end market.

Question · Q4 2024

Brian Biros asked about the future M&A strategy for the exterior building products space following the Zahner acquisition. He also inquired about the key variables that would drive results to the high or low end of the 2025 guidance range.

Answer

CEO Vic Grizzle stated that with less than 10% share in the new $1 billion exterior TAM, there is significant room for organic growth, but the company will remain 'open for business' for further bolt-on acquisitions. CFO Chris Calzaretta identified overall macroeconomic conditions and the degree of market 'chop' as the primary variables influencing performance within the guidance range.

Brian Biros's questions to Core & Main (CNM) leadership

Question · Q2 2026

Brian Biros asked about the drivers behind the revised guidance, specifically how the significant adjustment to the residential outlook was partially offset by positive factors like municipal market strength or recent M&A, and inquired about the biggest growth opportunities in the evolving water market, considering AI infrastructure and reindustrialization trends.

Answer

Robyn Bradbury (CFO) explained that the residential decline was the primary driver for the sales guide reduction, but bright spots like treatment plants, fusible High-density polyethylene, and a strong municipal market provided offsets. Mark Witkowski (CEO) highlighted the favorable water market, increased demand from data centers, improved value of water, healthy municipalities, and the multi-year tailwinds from aging infrastructure, noting these help offset temporary residential headwinds.

Question · Q1 2025

Brian Biros asked about the specific drivers behind the outperformance of the storm drainage product category and questioned the company's path to achieving its long-term 15% EBITDA margin target set at its Investor Day.

Answer

CFO Robyn Bradbury attributed strong storm drainage growth to M&A, organic growth in road and bridge projects fueled by infrastructure funding, and a product shift toward materials sold through distribution. CEO Mark Witkowski expressed confidence in reaching the 15% EBITDA margin target, noting that the initial forecast accounted for some margin normalization and that M&A has provided more opportunities for synergies.

Question · Q4 2024

Brian Biros asked if the company's market outperformance expectations differ by end market, particularly between the slower residential and stronger municipal sectors. He also questioned if the new administration was having any effect on the ease or speed of project permitting.

Answer

CFO Mark Witkowski stated that while outperformance was generally similar across end markets, it was likely weighted slightly more toward the municipal side in 2024 due to strength in smart meters and treatment plant projects. CEO Steve LeClair commented that while there is encouraging talk about easing regulatory requirements for permits, he has not yet seen specific examples of this accelerating projects.

Question · Q4 2024

Requested more detail on non-residential demand, specifically the dynamic between new construction and repair/reroof (R&R), and whether the R&R demand is accelerating.

Answer

Executives explained that past supply chain issues prioritized new construction, delaying R&R projects. Now, with supply normalized and new construction slowing (indicated by the Architectural Billing Index), there is a remixing toward the steady, non-discretionary R&R cycle. They described it as more of a catch-up and mix shift rather than a bullish acceleration in R&R demand. The company is also deliberately focused on gaining share in commercial markets.

Question · Q3 2024

Inquired about the non-residential market, asking for details on the performance of specific verticals, the shift from new construction to R&R, and the overall outlook for the non-residential sector heading into 2025.

Answer

Executives stated that delayed commercial repair and replace (R&R) activity has picked up as new construction has faded, with warehouses, data centers, hospitals, and schools being strong verticals. The shift to R&R involves a different product mix but has held up better than expected. They remain 'cautiously optimistic' about the commercial outlook, though new construction is expected to remain muted due to high interest rates.
