Q1 2026

  1. 01 · Upper band

    Plumbing service business, 48% service agreement revenue, three master licenses on staff

    Observed: Service agreements at 48% of trailing revenue with documented renewal rates. Three master plumber licenses across two jurisdictions — none held by owner. Fleet 4.8-year average age with full service records. Emergency revenue normalized to 3-year average.

    Outcome: Signed at 4.2× SDE. Lender DSCR 1.26× on normalized earnings. Closed without repricing.

    Composite
  2. 02 · Mid-band

    Residential plumbing contractor, owner performs 35 hours/week, single master license

    Observed: Owner is the sole master plumber on staff and performs 35 billable hours per week. Service agreements at 31% of revenue. Emergency call revenue 28% of total — presented as recurring. Fleet 6.5-year average with one van past 9 years.

    Outcome: Initial ask 3.8× stated SDE. After owner-labor normalization and emergency revenue restatement to run-rate, adjusted SDE reduced 44%. Repriced to 2.9× adjusted SDE. License continuity plan (hire journeyman, 9-month master exam path) required before credit approval. Closed at 2.9×.

    Composite
  3. 03 · Lower band

    Single-plumber shop, no service agreements, fleet over 9 years, owner runs all jobs

    Observed: Owner is sole master plumber and sole licensed operator. No service agreements — 100% of revenue from emergency calls and project work. Fleet 9.2-year average. Owner performs all high-value jobs personally with no plan for replacement.

    Outcome: Buyer submitted LOI at 2.7× stated SDE. After owner-labor normalization, adjusted SDE was negative. Deal terminated — no fundable structure exists for a business requiring owner-operator labor to generate positive SDE.

  • Outcome

    What happened — closed, repriced, financing fell through, walked. We report. We do not claim the score "told you to" do anything.
