    Guidance / outlook

    we expect these factors to provide a meaningful benefit to PEM's margins through at least the summer of 2026. We expect HIP sales volume to be supported by continued infrastructure spending, including strong demand from new data centers, although interest rates and increased building costs are likely to keep home affordability as a headwind to sales volume growth.
