The Iron Triangle is MAI's proprietary signal convergence framework. In an internal backtest against 340+ completed M&A samples, the strongest signal combinations reached 93.3% precision in identifying active M&A processes — a 17.5x lift over the base rate — with a 44-day median lead time.
Each component of the Iron Triangle represents a distinct stage in a company's path toward a transaction. Individually, each signal has moderate predictive value. When all three converge on the same company within their decay windows, it indicates a company that has acknowledged, prepared for, and formalized a potential sale.
Natural language processing detects merger-related terminology in SEC filings (10-K, 10-Q, 8-K) — phrases like "strategic review," "exploring alternatives," "potential transaction," and "change of control." MAI scans for 20 distinct textual patterns.
A public statement that the company is "exploring strategic alternatives" — corporate language for considering a sale, merger, or significant restructuring. Typically disclosed in 8-K filings or press releases. One of the strongest standalone sell signals.
Hiring of an investment bank or financial advisor for strategic purposes. When a company retains a bank like Goldman Sachs, Lazard, or Houlihan Lokey for a "strategic review," it signals a formal process is underway or imminent.
A single sell-intent signal can be a false positive. A company might announce strategic alternatives and then decide to stay independent. An advisor might be engaged for debt restructuring rather than a sale. M&A language in a filing might be boilerplate.
But when all three converge on the same company, it tells a coherent story:
The company has acknowledged the possibility of a sale (strategic alternatives), hired professional help to run a formal process (advisor engagement), and embedded M&A-related language in official regulatory filings (M&A language NLP). In MAI's internal backtests, this triple confirmation materially reduced false positives.
MAI backtested the Iron Triangle methodology against 340+ completed M&A samples across its monitored public-company universe. The results below are internal backtest metrics and are not presented as an independently audited benchmark.
Precision: 93.3% — In the internal backtest sample, the highest-conviction signal combinations identified active M&A processes with 93.3% precision.
Lift: 17.5x — Against the internal base rate, signal convergence produced a 17.5x improvement over random selection.
Recall: 45% — The Iron Triangle captures 45% of all acquisitions that occurred. The remaining 55% were acquired through processes that didn't generate all three signal types (e.g., unsolicited bids, private negotiations).
Lead time: 44 days — Signals fired a median 44 days before deal completion or public announcement in the internal sample, giving teams time to evaluate opportunities.
Coverage: 99.4% — In the completed-deal sample, nearly all deals had at least one prior sell-intent signal before announcement.
The LOI (Letter of Intent) + Strategic Alternatives combination offers a different precision/recall tradeoff:
43.4% precision 8.1x lift 55% recall 57-day lead time
This combination captures more deals (55% vs. 45%) at the cost of lower precision, which may be preferable for buyers who want broader coverage and can tolerate more false positives.
The Iron Triangle operates within MAI's broader decay-weighted, role-aware scoring engine that processes 25+ proprietary signal dimensions into a company-level review score.
Companies are classified by their role in M&A activity. Targets receive a weight of 60, acquirers receive 0 (since buyer activity doesn't indicate sell intent), and unknown companies receive 15. This prevents acquirer signals from contaminating target identification.
Signals lose weight over time at type-specific rates, reflecting how long each signal remains predictive:
Strategic alternatives: 180 days Advisor engagement: 180 days Sale of company: 180 days Going private: 120 days Unsolicited proposal: 120 days LOI: 90 days Executive departure: 60 days Tender offer: 45 days
When all three Iron Triangle signals converge on a single company within their active decay windows, a +50 point bonus is applied to the company's score. This bonus, combined with the individual signal scores, typically pushes the company well above the "hot" threshold.
Companies scoring ≥120 points with at least 2 distinct signal types are classified as "hot" — the highest probability acquisition targets. A single signal is capped at 30 points to prevent isolated events from triggering false alerts.
MAI tracks 40,000+ M&A-related signals, 6,000+ actively monitored US public companies, and 10M+ private company profiles across its research and approved partner workflows.
