WETYR works alongside primary sources, regulators, and industry data providers when advising owners and operators. The references below are the same sources our advisory team uses when modeling deals, benchmarking multiples, and stress-testing assumptions. We encourage every owner, buyer, and operator to verify any data point that materially affects their decision against the underlying primary source.

- SEC EDGAR for public-company comparables, 10-K disclosures, and recent strategic acquirer filings.
- IRS — Sale of a Business on Section 1060 asset-allocation reporting and tax treatment of asset vs stock sales.
- U.S. Bureau of Labor Statistics — Industries at a Glance for wage, employment, and growth data by NAICS code.
- U.S. Census Economic Census for industry size, firm counts, and revenue distributions.

For deeper transaction-specific data, the GF Data and PitchBook private-company transaction databases publish quarterly multiple ranges by industry size band that we cross-reference against our own pipeline benchmarks. Owners considering a sale should also review the Pepperdine Private Capital Markets Report (free, annual) for current cost-of-capital and lender appetite data across the lower middle market. Buyers underwriting search-fund or holdco theses commonly pair Stanford GSB's Search Fund Study with the IBBA Market Pulse report, which tracks multiples for sub-$50M transactions quarterly. None of these sources replace deal-specific advisory, but they give owners and operators the same reference points professional acquirers are using on the other side of the table.
