Search Fund Acquisition Underwriting: How ETA Principals Differ From PE Buyers on Deal Math

Search fund principals apply different underwriting math because their capital structure, operating role, and return timeline differ from PE fund buyers. The differences are not adjustments to PE methodology. They are different methodology.

The structural differences include:

• Capital structure. PE funds acquire with committed LP capital and syndicated senior debt at 4.5 to 5.5x EBITDA leverage. Search funds acquire with SBA financing (up to $5M per loan), search fund lender financing (typically 3.0 to 4.0x EBITDA), and equity from search fund investors. The lower leverage ceiling caps the multiple search funds can pay at a given EBITDA level.
• Operating role. PE funds install management or retain existing management. Search fund principals operate the business themselves. Management dependency assessment shifts from "can the business run without the seller" to "can the business run under the principal's leadership."
• Return timeline. PE funds target 3 to 5 year holds with exit as the primary return event. Search funds may hold 7 to 15 years with returns generated through operating cash flow, principal compensation, and eventual exit.
• Investor governance. PE funds report to LP investors quarterly with institutional cadence. Search fund investors receive different reporting reflecting the principal's dual role and longer hold horizon.
• Follow-on capital. PE funds have fund reserves for follow-on capital. Search fund principals may lack follow-on capital access, making initial capital structure discipline more critical.

Search fund leverage ceilings reflect the financing sources available and the DSCR requirements including principal compensation. The math produces materially different leverage capacity than PE-backed LBOs.

• SBA 7(a) financing. SBA loans for acquisitions cap at $5M principal amount at approximately SBA reference rate plus 2.5 to 3 percent. For acquisitions above $5M enterprise value, SBA loans cover only a portion of the acquisition debt.
• Search fund lender financing. Specialized lenders (Live Oak, Pinnacle, others) provide search fund acquisition financing typically at 3.0 to 4.0x EBITDA. Rates run higher than PE-backed senior debt reflecting the smaller deal size and non-fund borrower profile.
• Seller notes. Search fund transactions frequently include seller notes at 15 to 25 percent of purchase price to bridge the gap between acquirer equity, SBA/search fund debt, and purchase price.
• Equity from search fund investors. Search fund investors typically fund 40 to 60 percent of the acquisition equity in exchange for preferred returns and equity participation.

Consider an illustrative search fund acquisition at $18M EBITDA and $130M purchase price (7.2x multiple):

Attempted PE-style structure:

• Senior debt at 5.0x EBITDA: $90M, not available in search fund market.
• Actual maximum debt available: 3.5 to 4.0x EBITDA equals $63M to $72M.
• Equity requirement: $58M to $67M.
• Search fund investor capital may only support $30M to $40M.

The structure does not close at $130M purchase price. The transaction either restructures at lower purchase price (typically $100M to $110M) or does not close.

Realistic search fund structure at $110M:

• Search fund debt at 3.5x EBITDA: $63M.
• Seller note at 12 percent PIK: $22M (20 percent of purchase price).
• Search fund investor equity: $25M.
• Principal equity: $0 (typical) or minimal from personal capital.

Total capital structure: $110M. Actual free cash flow available for debt service: EBITDA of $18M less principal compensation of $300K to $500K less capex less working capital equals approximately $14M. DSCR against total debt service ~1.4x, meeting typical search fund lender requirements.

Search fund operating plans differ from PE value creation plans because the search fund principal is the CEO. The plan is not a value creation thesis delivered by installed management. It is the principal's own operating agenda.

The operating plan components include:

• Personal compensation embedded. The principal's compensation is a specific line item reducing free cash flow available for debt service. PE funds do not have this reduction because the operating CEO is separate from the capital structure. Search fund lenders specifically model principal compensation as a fixed obligation.
• Extended time horizon. Search fund operating plans typically extend 5 to 10 years reflecting the longer hold horizon. PE value creation plans typically target 3 to 5 years to exit.
• Growth funded from operating cash flow. Search fund principals typically lack follow-on capital access. Growth investment must come from operating cash flow, requiring the plan to balance growth investment against debt service and principal compensation.
• Institutional infrastructure buildout. The plan typically includes finance function buildout, management team development, and system infrastructure that PE-owned businesses may have inherited or installed at acquisition.
• Exit timing flexibility. Search fund principals have more flexibility on exit timing than PE funds. Exit typically occurs when institutional value is maximized, which may be 5 to 15 years post-acquisition.

Search fund principals face specific financial diligence gaps that differ from PE buyer gaps. The pattern reflects the search fund principal's typical background (business school MBA, limited prior transaction experience) and resource constraints.

The specific errors include:

• Seller EBITDA acceptance. Search fund principals frequently accept seller-adjusted EBITDA without independent normalization. The pattern reflects diligence budget constraints and inexperience with the eight-category examination. Post-close discovery of the EBITDA overstatement produces covenant compliance issues.
• Working capital acceptance at closing balance. Search fund principals frequently accept the seller's closing balance sheet working capital rather than commissioning 24-month normalized analysis. Post-close seasonal working capital requirements typically produce $2M to $8M in unmodeled cash consumption.
• Owner compensation treated as full add-back. Search fund principals frequently model full owner compensation as add-back without accounting for their own compensation post-close. The principal's compensation is an ongoing obligation that reduces free cash flow.
• Insufficient management assessment. Search fund principals assessing management (which they will manage as CEO) frequently apply insufficient rigor. Post-close discovery of management gaps typically requires urgent hiring at higher cost than diligence would have identified.

Four financial diligence gaps producing first-year lender compliance problems:

1. Undefended EBITDA add-backs. Lender's covenant EBITDA lower than principal's modeled EBITDA, producing covenant compression.
2. Working capital normalization absence. Working capital consumption exceeds modeled levels, drawing on revolver and increasing leverage.
3. Principal compensation modeled inconsistently. Modeled below actual paid compensation, understating debt service requirements.
4. Capex requirements underestimated. Insufficient capex allocation for maintenance and growth, producing operational stress.

Search fund return math incorporates three return components that PE fund IRR calculations do not: principal compensation over the hold period, carried interest through equity appreciation, and exit proceeds.

• Principal compensation. Salary and bonus over 5 to 15 year hold represents a substantial cash return. A principal earning $400K annually over 10 years generates $4M in compensation return separate from equity outcomes.
• Equity appreciation. The principal's equity stake (typically 15 to 25 percent after search fund investor economics) appreciates with business value. On a business acquired at $110M growing to $250M value over 10 years, principal equity at 20 percent share appreciates from base to $50M.
• Exit proceeds. At eventual exit, the principal's equity generates proceeds. Depending on structure and preferred returns to search fund investors, the principal may receive $15M to $40M on exit of a successful platform.

Combined return profile: $4M compensation plus $15M to $40M exit proceeds on typical successful search fund outcome. The return calculation differs materially from PE fund LP IRR calculations that focus solely on invested capital return.

Search fund investor returns are structured differently: preferred returns of 6 to 8 percent on invested capital plus equity participation that provides carry-like economics. Successful search fund investments typically produce 3 to 8x multiples on invested capital to search fund investors over 5 to 10 year holds.
