Most business owners call an M&A advisor once they’ve decided to sell. By then, the multiple is largely set — built or broken by the three years that came before. Buyers in 2026 aren’t paying for what a business could become; they’re paying for what it has already proven. We call this the Three-Year Rule: the practical framework for building a premium multiple before you ever launch a sale process. Our latest Watermark Wire walks through how each year compounds into the next, and why the work you do before going to market can matter more than the process itself.
Key Takeaways
- Year One — Foundation: a documented long-term strategy with 5-year projections, 3–5 years of clean, GAAP-compliant historical financials (a third-party CPA data book makes this painless), reduced key-person risk through management hires, and get a true M&A valuation — not a pro bono one.
- Year Two — Proof: financial trajectory that matches the strategy (e.g., growing recurring revenue over transactional revenue), management given real P&L authority, and the business plan documented outside the owner’s head so the company can run without them.
- Year Three — Position: an M&A advisor engaged, a sell-side Quality of Earnings (QofE) report completed, internal due diligence finished before the buyer’s team arrives, and a competitive process spanning search funds, private equity, and strategic buyers.
- The bottom line: a premium multiple isn’t negotiated in the final six months. It’s built over three years — watch the video below to see how.
