LBO Analysis for HarborTech Services (HTX)

1) Year-by-Year Table (FY2026–FY2030)

• Assumptions: Base case from provided data. All calculations use simplified model. Free cash flow after debt service is used for optional Term Loan paydown. Cash tax rate: 25% of (EBITDA - cash interest). Change in NWC: 0.5% of incremental revenue (cash outflow). Capex: 3.0% of revenue. Term Loan amortization: 1% of initial principal ($4.8m/year). Mezzanine PIK: 2% of beginning balance (added to principal).

Year	Revenue ($m)	EBITDA ($m)	Cash Interest - Term Loan ($m)	Cash Interest - Mezzanine ($m)	Cash Taxes ($m)	Capex ($m)	ΔNWC ($m)	Free Cash Flow after Debt Service ($m)	Term Loan Balance ($m)	Mezzanine Balance ($m)
FY2026	972.0	136.1	43.2	21.6	17.8	29.2	0.4	19.5	455.7	183.6
FY2027	1,039.6	155.9	41.0	22.0	23.2	31.2	0.3	33.7	417.2	187.3
FY2028	1,101.9	176.3	37.5	22.5	29.1	33.1	0.3	49.4	363.1	191.0
FY2029	1,157.0	190.9	32.7	22.9	33.8	34.7	0.3	62.0	296.3	194.8
FY2030	1,214.9	206.5	26.7	23.4	39.1	36.4	0.3	76.1	215.4	198.7

Key Calculations:

• EBITDA: Revenue × EBITDA margin.
• Cash Interest: Term Loan (9% of beginning balance), Mezzanine (12% of beginning balance).
• Cash Taxes: 25% × max(0, EBITDA - (Term Loan + Mezzanine cash interest)).
• Capex: 3% × Revenue.
• ΔNWC: 0.5% × (Current year revenue - Prior year revenue).
• Free Cash Flow after Debt Service: (EBITDA - Capex - Cash Taxes) - (Term Loan cash interest + Mezzanine cash interest + Term Loan amortization). If positive, used to pay down Term Loan.
• Term Loan Balance: Prior year balance - Amortization - Optional paydown (from FCF).
• Mezzanine Balance: Prior year balance + PIK (2% × prior year balance).

2) Equity IRR and MOIC

• Initial Equity Investment:
  • Enterprise Value (EV) = 12.0 × $120m = $1,440m.
  • Debt = 5.5 × $120m = $660m.
  • Equity = EV - Debt + Transaction Fees (2% of EV) = $1,440m - $660m + (0.02 × $1,440m) = $780m + $28.8m = $808.8m.
• Exit Value (FY2030):
  • Exit EV = 10.5 × $206.5m = $2,167.0m.
  • Exit Fees: 1% × $2,167.0m = $21.7m.
  • Proceeds after Fees = $2,167.0m - $21.7m = $2,145.4m.
  • Debt Repayment: Term Loan ($215.4m) + Mezzanine ($198.7m) = $414.1m.
  • Equity Value at Exit = $2,145.4m - $414.1m = $1,731.3m.
• MOIC (Multiple on Invested Capital) = Equity Value at Exit / Initial Equity = $1,731.3m / $808.8m = 2.14x.
• Equity IRR:
  • Solve: $808.8m × (1 + IRR)^5 = $1,731.3m → (1 + IRR) = (1,731.3 / 808.8)^(1/5) = 2.140^(0.2) = 1.164 → IRR = 16.4%.

3) Sensitivity of Equity IRR

• Vary Exit Multiple and Exit-Year EBITDA Margin:
  • Base Case: Exit Multiple = 10.5x, EBITDA Margin = 17.0% → IRR = 16.4%.
  • Sensitivity Table:

Exit Multiple	Exit-Year EBITDA Margin	Equity IRR
9.5x	16.0%	12.0%
9.5x	17.0%	13.8%
9.5x	18.0%	15.0%
10.5x	16.0%	14.3%
10.5x	17.0%	16.4%
10.5x	18.0%	18.8%
11.5x	16.0%	17.0%
11.5x	17.0%	19.6%
11.5x	18.0%	20.0%

4) Underwriting Risks and Downside Protection Levers

• 5 Underwriting Risks:

  1. Revenue Growth Decline: Lower demand from data center clients reduces growth (e.g., FY2028–2030 growth below 5%).
  2. Margin Compression: Competitive pressures or cost inflation prevents EBITDA margin expansion (e.g., exit margin < 17%).
  3. Higher Working Capital: Increased inventory or receivables tie up cash (e.g., ΔNWC > 0.5% of revenue).
  4. Interest Rate Hikes: If debt is floating (not fully captured here), rising rates increase interest expense.
  5. Customer Concentration: Loss of key clients (e.g., top 5 clients contribute >30% of revenue) impacts stability.

• 5 Concrete Downside Protection Levers:

  1. Cost Rationalization: Reduce SG&A expenses by 10–15% to boost EBITDA margins.
  2. Asset Sales: Monetize non-core equipment via sale-leasebacks to pay down Term Loan.
  3. Supply Chain Optimization: Renegotiate vendor contracts to lower capex (e.g., reduce to 2.5% of revenue).
  4. Working Capital Efficiency: Implement stricter invoicing/payment terms to cut NWC needs (e.g., reduce ΔNWC to 0.2%).
  5. Refinancing: Extend debt maturities or secure lower-cost financing pre-exit if market improves.

Summary: Base-case IRR of 16.4% and MOIC of 2.14x are achievable. Sensitivities show IRR ranges from 12.0% (low multiple, low margin) to 20.0% (high multiple, high margin). Risks are mitigated by operational levers to protect cash flow and reduce leverage.
