Notes

• Term‑Loan amortisation = 1 % of the original $480 m ($4.8 m) each year + any optional pay‑down.
• Mezzanine cash interest = 12 % of the outstanding mezz balance; a 2 % PIK accrues to principal each year.
• Taxes are 25 % of EBITDA – cash interest (no tax shield on PIK).
• All free cash flow after the mandatory amortisation is used to optional pay‑down the term loan (no dividends).

1️⃣ Equity Returns – Base Case (Exit Multiple = 10.5×, EBITDA margin = 17 %)

Item	Amount
Equity invested (t0)	–$808.80 m (purchase price $1 440 m – debt $660 m + transaction fee $28.8 m)
Cash‑flow FY2026‑FY2029	$0 (all cash used for debt repayment)
Cash‑flow FY2030 (exit)	$1 732.95 m (see calculation below)
Equity IRR	≈ 16.4 %
Equity MOIC	2.14×

Exit cash‑flow calculation (base case)

• FY2030 EBITDA = $206.63 m
• Exit EV = 10.5 × EBITDA = $2 169.56 m
• Exit fees = 1 % × EV = $21.70 m
• Debt repaid = Term‑Loan $216.18 m + Mezzanine $198.73 m = $414.92 m
• Equity proceeds = EV – fees – debt = $1 732.95 m

IRR = ((1 732.95/808.80)^{1/5} - 1 = 16.4 %) ; MOIC = 1 732.95 / 808.80 = 2.14×.

3️⃣ Key Underwriting Risks

#	Risk	Why it matters
1	Revenue growth slower than 8‑5 %	A 2 % shortfall cuts EBITDA by >$10 m each year, reduces cash‑flow for debt pay‑down, and lowers exit proceeds.
2	EBITDA margin compression	If margins fall 2 % points (e.g., to 15 % in FY2028) EBITDA drops ≈$20 m, eroding cash‑flow and equity value.
3	Higher capex or NWC needs	Capex >3 % of revenue or ΔNWC >0.5 % of incremental revenue would consume cash that would otherwise pay down debt, increasing leverage at exit.
4	Interest‑rate / refinancing risk	The term‑loan is fixed at 9 % but may need refinancing after 5 yr; a rise in rates would increase cash‑interest and reduce cash‑flow.
5	Operational risk in data‑center HVAC	Service contracts are mission‑critical; a major service‑failure event could trigger penalties, loss of contracts, and reputational damage.

---

4️⃣ Down‑side Protection Levers

#	Lever	How it protects equity
1	Cash‑sweep covenant (mandatory use of excess cash to repay term‑loan)	Guarantees that any free cash flow beyond the planned optional pay‑down automatically reduces leverage, limiting downside equity exposure.
2	Senior‑first lien with 1 % annual amortisation	Provides a clear schedule for debt reduction and ensures senior lenders are paid before mezzanine at exit.
3	Mezzanine PIK accrual capped at 2 %	Limits the growth of mezzanine principal, keeping total debt at exit predictable.
4	Financial covenants – EBITDA‑coverage ≥ 3.0×	Forces the company to maintain sufficient earnings to cover interest, triggering remedial actions if breached.
5	Equity “reset” or earn‑out clause	Allows the PE sponsor to adjust the purchase price or receive additional equity if EBITDA margins fall below a pre‑agreed floor, sharing upside/downside with the seller.

---

Bottom line:

• Base‑case equity IRR ≈ 16.4 % with a 2.14× MOIC.
• The investment is most sensitive to the exit multiple and the FY2030 EBITDA margin; a 2 × spread in exit multiple (9.5‑11.5×) moves IRR from ~12 % to ~21 %.
• The key risks revolve around growth, margin, capex/NWC, interest‑rate exposure, and operational execution, while the listed covenants and cash‑sweep mechanisms provide solid downside protection.

5. KEY UNDERWRITING RISKS

#	Risk	Impact	Likelihood
1	Revenue growth underperformance – Macro slowdown, customer churn, or competitive pricing pressure reduces growth from 8% → 4%.	FY2030 EBITDA falls ~15–20%; leverage remains >3.5x; IRR → 22–24%.	Medium
2	EBITDA margin compression – Labor inflation, supply chain costs, or service delivery inefficiency erode margins; 17% target → 15%.	EBITDA ~$185m (vs. $206m); exit value falls 10%; IRR → 24–26%.	Medium
3	Exit multiple contraction – Buyer sentiment weakens (recession, sector rotation, or higher rates); 10.5x → 8.5x.	Enterprise value falls ~19%; IRR → 18–20%.	Medium-High
4	Customer concentration / contract renewal risk – Loss of 1–2 large data center customers or unfavorable contract renegotiations; revenue impact −5–10%.	Recurring revenue model mitigates, but 5% loss → $60m EBITDA impact; leverage spikes to 3.8–4.0x.	Medium
5	Interest rate / refinancing risk – TL rates spike at refinancing; 9% → 11–12% (100–300 bps). Mezz difficult to refinance.	Annual cash interest +$10–15m by FY2028; FCF reduced; deleveraging stalls.	Low-Medium

---

6. DOWNSIDE PROTECTION LEVERS

#	Lever	Mechanism	Impact
1	Accelerated deleveraging covenant	Tie optional prepayment to leverage threshold: if leverage > 4.0x, 50% of FCF → TL paydown (vs. 100% today).	Reduces refinancing risk; by FY2028, leverage <3.5x even in downside.
2	Margin maintenance / operational KPIs	Covenant EBITDA margin ≥ 15.0% annually. Triggers remedial plan if missed (cost actions, pricing increases).	Forces discipline; protects 15% floor; limits compression to 17% → 15% scenario.
3	Revenue/customer concentration limits	Covenant: no single customer >15% of revenue; top 3 customers <40%. Annual customer review.	Mitigates customer loss concentration; forces diversification.
4	Term Loan amortization step-up	Increase mandatory amortization from 1.0% to 1.5% if leverage > 4.0x for 2+ consecutive quarters.	Faster deleveraging in stress; TL paid to ~$380m by FY2030 (vs. $339m).
5	Equity rollover / sponsor reinvestment	Sponsor retains 10–15% equity; sponsor commits to $50–75m equity cure if leverage > 5.0x or covenant breach.	Alignment; backstop for refinancing or covenant waiver.

7. SUMMARY & RECOMMENDATION

Metric	Value	Assessment
Entry Leverage	5.5x	Moderate; in line with cash-generative, recurring-revenue model.
Exit Leverage	2.72x	Conservative; strong deleveraging trajectory.
Base Case IRR	30.1%	Strong; exceeds typical 25%+ PE hurdle.
Downside IRR (9.5x / 16%)	23.8%	Acceptable; above 20% floor in stress.
MOIC	1.96x	Solid 5-year return; ~14% CAGR on equity.

Recommendation: APPROVE

Strengths:

• Mission-critical, recurring revenue model (data center HVAC) with high switching costs.
• Strong EBITDA growth (14% → 17% margin expansion) supported by operational leverage.
• Robust deleveraging: 5.5x → 2.7x over 5 years.
• Downside protection: even at 9.5x exit / 16% margin, IRR >23%.

Conditions:

• Embed leverage maintenance, margin, and customer concentration covenants.
• Secure sponsor equity rollover (10–15%) for alignment.
• Conduct deep customer/contract diligence; validate 8% revenue growth assumptions.
• Stress test for 200 bps margin compression and 100 bps rate increase.

4) KEY RISKS & DOWNSIDE PROTECTIONS

5 Underwriting Risks

#	Risk	Impact
1	Customer concentration – Top hyperscalers (AWS, MSFT, GOOG) likely 50%+ of revenue; loss of 1 contract = material EBITDA hit	Revenue/margin miss
2	Margin expansion failure – 13.3% → 17.0% assumes operational improvements that may not materialize (labor inflation, parts costs)	FCF compression, leverage stays elevated
3	Technology disruption – Liquid cooling / AI-driven predictive maintenance could commoditize traditional HVAC services	Multiple compression at exit
4	Labor scarcity – Specialized data center techs in short supply; wage inflation above plan	Margin squeeze
5	Multiple compression – Entered at 12x; exiting at 10.5x already assumes 1.5 turn compression; could be worse in risk-off market	Equity value destruction

5 Downside Protection Levers

#	Lever	Mechanism
1	Contracted revenue floor – Negotiate 3-5 year MSAs with 80%+ of revenue locked; include CPI escalators	Protects top-line in downside
2	Management rollover + earnout – Require 15-20% rollover; tie earnout to EBITDA margin milestones	Alignment on margin expansion
3	Covenant package – Springing leverage covenant at 5.0x; excess cash flow sweep at 75% above 3.0x leverage	Forces deleveraging discipline
4	Tuck-in M&A pipeline – Identified 3-4 regional players at 6-7x; accretive consolidation provides margin/multiple upside	Creates value even if organic growth slows
5	Capex flexibility – 3% capex is largely maintenance; can defer growth capex in downside to preserve ~$20M+ FCF annually	Liquidity buffer in stress case

---

INVESTMENT RECOMMENDATION

Base case returns (18.2% IRR / 2.3x MOIC) meet hurdle, but the deal is tight on downside:

• At 9.5x exit / 16% margin: 13.6% IRR / 1.9x – below typical 15%/2.0x thresholds
• Entry multiple (12x) leaves limited margin of safety

Proceed with caution – recommend negotiating price to 11x or securing contracted revenue visibility before final commitment.

Debt Balances & Interest – Detailed Walkthrough

Term Loan (TL): 9.0% cash interest, 1.0% annual mandatory amortization on original principal ($4.8m/yr), plus optional paydown from excess FCF.

Mezzanine: 12.0% cash interest on BoP balance, 2.0% PIK accrues to principal. No amortization; repaid at exit.

I'll compute each year sequentially since TL balance depends on prior-year optional paydown, and Mezz balance compounds with PIK.

---

FY2026

Debt balances (BoP): TL = $480.0m, Mezz = $180.0m

Cash Interest:

• TL: $480.0m × 9.0% = $43.20m
• Mezz: $180.0m × 12.0% = $21.60m
• Total Cash Interest = $64.80m

PIK accrual on Mezz: $180.0m × 2.0% = $3.60m

Cash Taxes: 25% × max(0, EBITDA − Total Cash Interest) = 25% × ($136.08 − $64.80) = 25% × $71.28 = $17.82m

Capex: 3.0% × $972.0 = $29.16m

ΔNWC: 0.5% × ($972.0 − $900.0) = 0.5% × $72.0 = $0.36m

Free Cash Flow (before debt paydown): $$FCF = EBITDA - Cash\ Interest - Cash\ Taxes - Capex - \Delta NWC$$ $$= 136.08 - 64.80 - 17.82 - 29.16 - 0.36 = $23.94m$$

Mandatory TL Amortization: $480.0 × 1.0% = $4.80m

FCF after mandatory amort (available for optional paydown): $23.94 − $4.80 = $19.14m → all applied to TL

EoP Balances:

• TL: $480.0 − $4.80 − $19.14 = $456.06m
• Mezz: $180.0 + $3.60 = $183.60m

3) SENSITIVITY TABLE: EQUITY IRR

To build the sensitivity, I vary exit EBITDA margin in FY2030 (holding FY2030 revenue at $1,215.5m constant, and holding all prior years and debt balances unchanged — the margin change only affects exit-year EBITDA for valuation purposes).

FY2030 EBITDA at each margin:

• 16.0%: $1,215.5 × 16.0% = $194.5m
• 17.0%: $1,215.5 × 17.0% = $206.6m (base)
• 18.0%: $1,215.5 × 18.0% = $218.8m

Debt at exit (constant): TL $217.0m + Mezz $198.7m = $415.7m

Note: 16.0% margin = $194M EBITDA; 17.0% = $207M; 18.0% = $219M

5. Key Underwriting Risks

1. Customer Concentration Risk - Loss of major data center clients could severely impact recurring revenue base
2. Technology Disruption - Shift to cloud/edge computing or automated monitoring could reduce service demand
3. Margin Compression - Labor inflation and technician shortage could pressure 300bps margin expansion assumption
4. Economic Downturn - Recession could delay data center expansion and reduce maintenance spending
5. Refinancing Risk - High leverage (5.5x) requires successful refinancing in potentially adverse credit markets

6. Downside Protection Levers

1. Recurring Revenue Model - 85%+ recurring contracts provide cash flow stability and visibility
2. Mission-Critical Service - HVAC failure = data center shutdown, making service non-discretionary
3. Fragmented Market - Opportunity for bolt-on acquisitions to accelerate growth and gain scale
4. Working Capital Management - Optimize payment terms and inventory levels to improve cash conversion
5. Cost Structure Flexibility - Variable technician workforce and scalable overhead provide operational leverage in downturns

Investment Recommendation: PROCEED - Attractive 16.5% base case IRR with strong downside protection from recurring revenue model and mission-critical service positioning.

Debt Schedule

Key mechanics:

• Term Loan: 1% annual amortization on original principal ($480m × 1% = $4.8m/yr mandatory); excess FCF sweeps optionally
• Mezzanine: PIK accrues to principal; no cash amortization until exit
• Cash interest = rate × beginning-of-year balance

Mezzanine PIK Accrual (no optional paydown):

	BOP Balance	Cash Int (12%)	PIK (2%)	EOP Balance
FY2026	180.0	21.6	3.6	183.6
FY2027	183.6	22.0	3.7	187.3
FY2028	187.3	22.5	3.7	191.0
FY2029	191.0	22.9	3.8	194.8
FY2030	194.8	23.4	3.9	198.7

PIK = 2% × BOP balance; EOP = BOP + PIK (cash interest paid, not added)

SECTION 2: EXIT & RETURNS

Exit Proceeds

Exit Enterprise Value:

EV = 10.5x × $206.6m = $2,169.3m

Exit Fees:

1.0% × $2,169.3m = $21.7m

Net Proceeds to Equity:

Item	$m
Exit EV	2,169.3
Less: Exit Fees	(21.7)
Less: Mezz Repayment (incl. PIK)	(198.7)
Less: Term Loan Repayment	(0)
Plus: Residual Cash	1.6
Equity Proceeds	1,950.5

MOIC

MOIC = Equity Proceeds / Equity Invested = $1,950.5m / $808.8m = 2.41x

IRR (5-year)

Using: IRR = (MOIC)^(1/n) − 1

IRR = (2.41)^(0.20) − 1

(2.41)^(0.20): ln(2.41) = 0.8796; 0.8796 × 0.20 = 0.1759; e^0.1759 = 1.1923

Equity IRR ≈ 19.2%

---

SECTION 3: SENSITIVITY TABLE — EQUITY IRR

Methodology

For each scenario, I recalculate FY2030 EBITDA using the sensitivity margin (holding revenue constant at $1,215.4m), compute exit EV, then derive equity proceeds and IRR. Debt at exit is held constant at base case ($198.7m Mezz + $0 TL + $1.6m cash) since operating cash flows change modestly with margin — for a clean sensitivity I hold debt paydown schedule constant and only vary exit valuation and EBITDA.

FY2030 EBITDA by margin scenario:

• 16%: $1,215.4m × 16% = $194.5m
• 17%: $1,215.4m × 17% = $206.6m ← base
• 18%: $1,215.4m × 18% = $218.8m

Exit EV, Net Equity Proceeds, MOIC, IRR:

Formula: Net Equity = EV×(1−1%) − 198.7 + 1.6; IRR = (Net Equity / 808.8)^0.2 − 1

	9.5x Exit	10.5x Exit	11.5x Exit
16% Margin
Exit EV	$1,847.8m	$2,042.8m	$2,237.3m
Net Equity	$1,630.1m	$1,823.2m	$2,015.9m
MOIC	2.01x	2.25x	2.49x
IRR	15.0%	17.6%	20.0%
17% Margin (Base)
Exit EV	$1,962.7m	$2,169.3m	$2,375.9m
Net Equity	$1,743.1m	$1,950.5m	$2,157.4m
MOIC	2.15x	2.41x	2.67x
IRR	16.5%	19.2%	21.7%
18% Margin
Exit EV	$2,077.6m	$2,295.9m	$2,514.2m
Net Equity	$1,856.1m	$2,073.0m	$2,289.4m
MOIC	2.29x	2.56x	2.83x
IRR	18.0%	20.7%	23.1%

IRR calculations use (MOIC)^(1/5) − 1. Exit fees = 1% of EV deducted.

Key Takeaway: The base case clears a 2.0x / 15% IRR hurdle in all but the worst scenario (9.5x / 16% margin = 15.0% IRR / 2.01x). The investment is most sensitive to exit multiple — a 1.0x turn swing moves IRR ~2.2 points, while a 1% margin swing moves IRR ~1.5 points.

SECTION 4: UNDERWRITING RISKS

5 Key Risks

1. Customer Concentration / Contract Non-Renewal HTS serves data centers under recurring contracts. If hyperscaler clients (likely top 3–5 = >40% revenue) in-source HVAC maintenance or switch vendors at renewal, revenue could cliff. The recurring revenue story is the core underwriting thesis — any disruption is existential to returns.

2. Labor Cost Inflation & Technician Scarcity HVAC maintenance is labor-intensive (field technicians). Wage inflation, union activity, or a structural shortage of certified technicians (HVAC + data center clearance) could compress margins significantly, directly threatening the 14%→17% margin expansion thesis (~370bps over 5 years).

3. Interest Rate / Refinancing Risk The deal is levered 5.5x at close with 9% TL / 14% all-in Mezz cost. While the FCF sweep deleverages aggressively, a credit market dislocation at exit could force a sale at depressed multiples or impair refinancing. The Mezz PIK accrual ($18.7m over 5 years) also quietly increases exit debt obligations.

4. Technology Disruption / Predictive Maintenance Displacement IoT-enabled remote monitoring and AI-driven predictive maintenance platforms could allow data centers to reduce on-site service frequency or shift to lower-cost providers. HTS's monitoring business could be commoditized, compressing both revenue growth and margins.

5. Data Center End-Market Cyclicality / Capex Freeze Data center construction and expansion drives new contract wins. A hyperscaler capex pullback (as seen periodically), cloud consolidation, or macro-driven IT spending freeze could reduce new contract flow, limiting the 5–8% revenue growth assumptions and the ability to cross-sell monitoring services.

---

SECTION 5: DOWNSIDE PROTECTION LEVERS

5 Concrete Mechanisms

1. Covenant Package with Springing Cash Sweep Negotiate a net leverage maintenance covenant (e.g., <5.0x) with a springing cash sweep that accelerates Term Loan paydown if leverage exceeds threshold. This protects against EBITDA deterioration by forcing deleveraging before the situation becomes distressed — the model already shows $340m of optional TL paydown over 5 years.

2. Contracted Revenue Lock-In (Multi-Year MSAs with Escalators) At close, prioritize renegotiating customer contracts to 3–5 year Master Service Agreements with CPI-linked price escalators (e.g., CPI + 1–2%). This converts lumpy renewal risk into a predictable revenue base and directly supports the margin expansion thesis by passing through labor cost inflation.

3. Mezz Conversion / PIK Toggle Option Negotiate a PIK toggle on the Mezzanine (ability to switch between cash pay and PIK) to preserve liquidity in a stress scenario. If EBITDA underperforms, toggling to full PIK saves $23–24m/year in cash interest, protecting the FCF sweep and avoiding a liquidity trap.

4. Operational Margin Levers: Route Density & Pricing Power Identify $15–20m of cost takeout through technician route optimization (geographic clustering of contracts) and procurement consolidation (parts/equipment buying power). This creates a "self-help" margin bridge that is partially independent of revenue growth, providing a floor against the margin expansion assumptions.

5. Strategic Buyer / Dual-Track Exit Optionality Given HTS's mission-critical positioning in the data center supply chain, identify 3–5 strategic acquirers (large facility management firms, HVAC OEMs with service ambitions, infrastructure-focused corporates) as exit alternatives to a sponsor-to-sponsor deal. Strategic buyers would likely pay 11–13x, providing a meaningful premium to the 10.5x base case and protecting against PE multiple compression at exit.

SUMMARY SCORECARD

Metric	Value
Entry EV	$1,440m
Entry Leverage	5.5x / $660m
Equity Invested	$808.8m
Exit EV (base)	$2,169.3m
Exit Debt	$198.7m
Equity Proceeds	$1,950.5m
MOIC	2.41x
IRR	~19.2%
Minimum IRR (stress)	~15.0% (9.5x / 16% margin)
Maximum IRR (upside)	~23.1% (11.5x / 18% margin)

IC Recommendation (Base Case): The investment clears a 2.0x / 15% hurdle in all but the most stressed scenario. The thesis is predicated on (1) mission-critical contract stickiness, (2) labor/route efficiency driving margin expansion, and (3) data center secular tailwinds supporting growth. Primary risks are contract concentration and technician cost inflation. Recommend proceeding subject to confirmatory diligence on top-10 customer contract terms and workforce cost structure.

Alright — let’s go step by step.

1) Entry Calculations (FY2025)

EBITDA = $120m
Purchase price = 12.0 × EBITDA = $1,440m
Enterprise Value (EV) = $1,440m (assumed purchase price = EV here)

Transaction fees = 2.0% × EV = $28.8m (funded by equity).

Total debt at close = 5.5 × EBITDA = $660m
Term Loan: 4.0 × EBITDA = $480m
Mezzanine: 1.5 × EBITDA = $180m

Equity contribution = Purchase price + fees − total debt
= $1,440m + $28.8m − $660m = $808.8m initial equity.

3) Exit and Returns

Exit FY2030 EBITDA = $206.62m
Exit multiple = 10.5× → EV = $2,169.51m
Exit fees = 1% × EV = $21.70m

Net debt at exit:
Term Loan = $189.51m
Mezz = $198.74m
Cash = $0 (FCF used to pay debt)
Total debt = $388.25m

Equity value at exit = EV − net debt − exit fees
= $2,169.51m − $388.25m − $21.70m = $1,759.56m

Initial equity = $808.8m

MOIC = $1,759.56m / $808.8m = 2.176x

IRR: Solve ( 808.8 = 1759.56 / (1+IRR)^5 ) → IRR ≈ 17.0% (annualized).

4) Sensitivity Table

Exit multiple vs Exit-year EBITDA margin (IRR %):

EBITDA margin →	16.0%	17.0% (base)	18.0%
9.5×	11.5%	13.7%	15.8%
10.5×	13.9%	16.0%	18.1%
11.5×	16.2%	18.3%	20.3%

Note: Calculated by adjusting FY2030 EBITDA (margin × revenue $1,215.44m), recomputing debt paydown from FY2029 end balances through FY2030 (interest/tax changes slightly), then exit EV, net debt, equity value, and IRR.

5) Underwriting Risks & Downside Protection Levers

Risks:

1. Margin pressure – labor cost inflation or contract re-pricing risk.
2. Customer concentration – data center market cyclicality.
3. Revenue growth slowdown – lower incremental revenue → less FCF for deleveraging.
4. Interest rate risk – floating Term Loan rate could rise.
5. PIK toggle mezzanine – compounding debt if FCF underperforms.

Protection levers:

1. Capex flexibility – can defer growth capex if needed.
2. Contract structure – inflation pass-throughs in service agreements.
3. Refinancing option – term out debt if rates decline.
4. Equity cure – sponsor can inject equity to avoid covenant breach.
5. Cost reduction program – opex levers to defend margins.

---

Final answer:
Base case IRR ≈ 17.0%, MOIC ≈ 2.18x, with sensitivities as above.

4. Underwriting Risks & Downside Protection

Underwriting Risks:

1. Multiple Compression: Entry at 12.0x is high; a return to historical service multiples (e.g., 9x) significantly erodes IRR.
2. Margin Expansion Aggression: Assuming nearly 400bps of margin expansion requires significant operating leverage or pricing power.
3. Interest Rate Volatility: With a 9% cash interest rate on the TL, any floating rate increases could choke FCF and prevent debt paydown.
4. Customer Concentration: Data center cooling is a niche; loss of a major hyperscale client would derail growth.
5. Labor Inflation: HVAC technicians are skilled labor; wage spikes could negate the projected EBITDA margin improvements.

Downside Protection Levers:

1. Contractual Escalators: Ensure multi-year contracts include CPI-linked pricing adjustments to protect margins from labor inflation.
2. Capex Deferral: Capex is 3% of revenue; in a cash crunch, "growth" capex can be scaled back to preserve liquidity for debt service.
3. Mezzanine PIK Toggle: Negotiate the ability to flip Mezzanine cash interest to PIK if DSCR falls below a certain threshold.
4. Operational Synergies: Conservative underwriting currently assumes organic growth; M&A of smaller regional HVAC players could provide "multiple arbitrage" and cost synergies.
5. Monitoring Revenue Mix: Focus on increasing the "monitoring" (software/recurring) revenue vs. "break-fix" to justify a higher exit multiple.

Exit Margin \ Exit Multiple	9.5x	10.5x	11.5x
16.0%	11.7%	14.6%	17.2%
17.0% (Base)	13.6%	16.5%	19.1%
18.0%	15.3%	18.2%	20.8%

5. Underwriting Risks & Downside Protection Levers

5 Underwriting Risks:

1. Customer Concentration: The data center market is dominated by a few hyperscalers (AWS, MSFT, Google); losing a single top-tier tenant contract could severely impact revenue.
2. Skilled Labor Shortage & Wage Inflation: HVAC technicians are in high demand. Wage inflation could outpace service contract price escalators, compressing margins.
3. High Entry Leverage: 5.5x starting leverage with expensive mezzanine debt leaves the business vulnerable to cash flow crunches if top-line growth stalls early in the hold period.
4. Data Center Capex Slowdown: A macro cooling of AI/cloud infrastructure build-outs would limit new greenfield service contract opportunities, risking the 5–8% growth projections.
5. Multiple Contraction: Entering at 12.0x leaves limited room for error. A shift in interest rates or market sentiment could compress exit multiples well below the modeled 10.5x (e.g., historical 8-9x HVAC averages).

5 Downside Protection Levers:

1. Mission-Critical Recurring Revenue: Data center cooling is non-discretionary (downtime costs millions). High switching costs and multi-year contracts provide a highly visible, sticky revenue floor.
2. Aggressive De-leveraging Sweep: By sweeping 100% of excess cash flow to the Term Loan, HTS rapidly de-risks the balance sheet, dropping senior leverage from 4.0x to ~1.0x by exit.
3. Asset-Light Capex Flexibility: With maintenance capex at only 3% of revenue, management can easily defer non-essential tech/fleet upgrades to preserve cash in a recessionary scenario.
4. Pass-Through Pricing Mechanisms: Service contracts can be structured with CPI-linked or wage-linked automatic escalators, shifting the burden of inflation directly to the end customer to protect EBITDA margins.
5. SG&A & Route Optimization: In a downside scenario, HTS can pause hiring, consolidate technician routing (improving utilization), and cut back-office overhead to defend the 14-17% margin profile.

Calculations:

• Cash Interest (TL): 4.0x EBITDA * 9.0% = 0.36x EBITDA
• Cash Interest (Mez): 1.5x EBITDA * 12.0% = 0.18x EBITDA
• Cash Taxes: max(0, EBITDA - Cash Interest) * 25%
• Capex: 3.0% of Revenue
• ΔNWC: 0.5% of Incremental Revenue (calculated as Annual Revenue Growth * Previous Year Revenue)
• Free Cash Flow (FCF): EBITDA - Capex - ΔNWC - Cash Interest
• Ending Debt: Beginning Debt + Cash Flow - Amortization (TL) - PIK (Mez)

Note: The table assumes the $120m EBITDA in FY2025 is the starting point for projecting subsequent years.

---

2) Equity IRR and MOIC

Initial Equity Investment:

• Purchase Price: 12.0x $120m EBITDA = $1,440m
• Transaction Fees: 2.0% of $1,440m = $28.8m
• Total Equity Invested: $1,440m + $28.8m = $1,468.8m

Exit Value:

• FY2030 EBITDA: $184.7m
• Exit Multiple: 10.5x EBITDA = $1,949.05m
• Exit Fees: 1.0% of $1,949.05m = $19.49m
• Net Exit Value: $1,949.05m - $19.49m = $1,929.56m

Equity IRR:

• Total Cash Flow: $1,929.56m - $1,468.8m = $460.76m
• IRR = (Ending Value / Initial Investment)^(1/Number of Years) - 1
• IRR = ($460.76m / $1,468.8m)^(1/5) - 1 = 13.65%

Equity MOIC:

• MOIC = (Net Exit Value / Initial Investment)
• MOIC = ($1,929.56m / $1,468.8m) = 1.31x

3) Sensitivity Analysis

Exit Multiple	Exit-Year EBITDA Margin	Equity IRR
9.5x	16%	12.5%
10.5x	17%	13.65%
11.5x	18%	14.8%

Note: These are approximate calculations based on the provided data and assumptions.

---

4) Underwriting Risks and Downside Protection Levers

Underwriting Risks:

1. Revenue Growth Slowdown: The base case assumes consistent growth. A significant downturn in data center demand or increased competition could impact revenue.
2. Higher Interest Rates: Unexpected increases in interest rates could significantly increase debt service costs, impacting FCF.
3. Increased Capex: Unforeseen capital expenditures (e.g., major infrastructure upgrades) could strain cash flow.
4. Working Capital Deterioration: Faster increases in NWC than projected could reduce free cash flow.
5. Data Center Consolidation/Churn: Loss of key data center clients or increased churn could negatively impact recurring revenue.

Downside Protection Levers:

1. Conservative Revenue Projections: Using lower revenue growth rates in sensitivity analysis.
2. Strong Contractual Base: The reliance on recurring service contracts provides a degree of revenue predictability.
3. Amortization of Debt: The annual amortization of the Term Loan reduces the principal balance over time, lowering interest expense.
4. Optional Term Loan Paydown: The ability to prioritize debt repayment provides flexibility in managing cash flow.
5. Operational Improvements: Focus on cost efficiencies and service enhancements to maintain or improve EBITDA margins.

5. Underwriting Risks & Downside Protection

Top 5 Risks:

1. Multiple Contraction: Entry at 12.0x vs Exit at 10.5x creates a significant valuation headwind; the investment relies heavily on EBITDA growth to offset the multiple decline.
2. Execution Risk: The plan requires expanding EBITDA margin from 13.3% to 17.0% in 5 years; failure to achieve operational efficiencies (scale, routing, purchasing) will crush returns.
3. Interest Rate Volatility: The Term Loan is floating rate; a sustained 200bps rate increase would significantly reduce free cash flow available for deleveraging.
4. Customer Concentration: "Data centers" implies a concentrated customer base (hyperscalers); loss of a single major contract could materially impact revenue.
5. Refinancing Risk: Mezzanine debt is expensive (14%+ all-in); if the credit markets are closed in Years 3–4, the company cannot refinance to lower interest costs, dampening equity value.

Top 5 Downside Protection Levers:

1. Recurring Revenue Base: Mission-critical maintenance contracts for data centers are non-discretionary and highly sticky, providing downside revenue protection.
2. Aggressive Deleveraging: The model generates ~$230m of cumulative FCF for debt paydown, reducing Net Debt from $660m to ~$446m, significantly lowering the equity breakeven point.
3. Margin Floor: Even if margin expansion fails, the business generates strong cash flow; at a constant 13.3% margin, the company still pays down debt, providing a cushion.
4. Asset Liquidity: HVAC service platforms are attractive to strategic buyers (e.g., HVAC manufacturers, facility management firms), providing an alternative exit path if financial sponsors are absent.
5. NWC Efficiency: The minimal NWC requirements (0.5% of incremental revenue) ensure cash flow conversion is high, preventing cash from being trapped in working capital during growth.

Let's proceed step by step. All calculations are built from the data provided above.

Step 2: Operating Forecasts

Revenue and EBITDA

Year	Growth	Revenue	Margin	EBITDA
FY2025	—	$900.0m	13.3%	$120.0m
FY2026	8%	$972.0m	14.0%	$136.1m
FY2027	7%	$1,039.0m	15.0%	$155.8m
FY2028	6%	$1,101.3m	16.0%	$176.2m
FY2029	5%	$1,156.4m	16.5%	$190.8m
FY2030	5%	$1,214.2m	17.0%	$206.4m

Capex

Capex = 3.0% of Revenue

Change in NWC

ΔNWC = 0.5% × (Current Yr Revenue – Prior Yr Revenue)

EBITDA – Cash Interest

We'll need to track debt balances for Term Loan and Mezzanine, as both amortize/accrete.

---

Step 3: Debt Schedules

Term Loan

• Starting: $480m
• Interest: 9.0% cash
• Amortization: 1.0% per year
• All excess FCF (after required payments) sweeps to paydown

Mezzanine

• Starting: $180m
• Interest: 12.0% cash + 2.0% PIK (PIK accrues to principal)
• Paid at exit (no principal paydown until exit)

B. Calculations Breakdown

• Capex: 3% × Revenue
• ΔNWC: 0.5% × (Revenue_this_year – Revenue_last_year)
• Term Loan Amortization: 1% × Beg Bal
• Term Loan Cash Interest: 9% × Beg Bal
• Mezzanine Cash Interest: 12% × Beg Bal
• Mezzanine PIK: 2% × Beg Bal
• Taxes: 25% × max(0, EBITDA – Total Cash Interest)
• FCF after Debt Service:
  • FCF = EBITDA – Capex – ΔNWC – Cash Interest (TL + Mezz) – Taxes – TL Amort
  • All FCF after required payments (above) goes to optional TL paydown

C. Debt Balances

• Term Loan End Bal: Prior year end – required amortization – optional paydown (from FCF)
• Mezz End Bal: Prior year + PIK

Optional Term Loan Paydown Calculation

• Any FCF after required payments is used to pay down the Term Loan (after required amortization).

Detailed Calculations (First Year Example: FY2026)

• Revenue: $972.0m
• EBITDA: $972.0m × 14% = $136.1m
• Capex: $972.0m × 3% = $29.2m
• ΔNWC: 0.5% × ($972.0m – $900.0m) = 0.5% × $72.0m = $0.36m (should be $0.36m, but above table uses $3.6m; let's double-check: 0.5% × $72m = $0.36m, but above is $3.6m, so let's use $0.36m as the correct value)
• Term Loan Beg Bal: $480.0m
  • Interest: 9% × $480m = $43.2m
  • Amortization: 1% × $480m = $4.8m
• Mezz Beg Bal: $180.0m
  • Cash Interest: 12% × $180m = $21.6m
  • PIK: 2% × $180m = $3.6m
• Taxes: 25% × ($136.1m – $43.2m – $21.6m) = 25% × $71.3m = $17.8m
• FCF after Debt Service:
  • $136.1m – $29.2m – $0.36m – $43.2m – $21.6m – $17.8m – $4.8m = $19.14m
• Optional Paydown: $19.14m goes to Term Loan paydown

Term Loan End Bal: $480m – $4.8m – $19.14m = $456.1m

Mezz End Bal: $180m + $3.6m = $183.6m

(I will correct the NWC to $0.36m per year, not $3.6m as previously)

Let me recalculate the table with this fix.

2. Equity IRR and MOIC Calculation

A. Exit Calculation (End of FY2030)

• Exit EBITDA: $206.4m
• Exit Multiple: 10.5x
• Enterprise Value: $206.4m × 10.5 = $2,166.7m
• Exit Fees: 1% × $2,166.7m = $21.7m
• Net Proceeds: $2,166.7m – $21.7m = $2,145.0m
• Less Debt Repayment:
  • Term Loan: $228.0m
  • Mezzanine: $198.7m
  • Total Debt: $426.7m
• Equity Value at Exit: $2,145.0m – $426.7m = $1,718.3m

B. Entry Equity

• Entry Equity: $808.8m

C. MOIC

• MOIC = $1,718.3m / $808.8m = 2.13x

D. IRR

• Entry: –$808.8m at end 2025 (t=0)
• Exit: +$1,718.3m at end 2030 (t=5)

[ IRR = \left(\frac{$1,718.3}{$808.8}\right)^{1/5} - 1 = (2.126)^{0.2} - 1 \approx 16.0% ]

3. Sensitivity Table: IRR vs Exit Multiple and EBITDA Margin

Assume:

• Exit Year EBITDA = Revenue × Margin
• FY2030 Revenue: $1,214.2m
• Debt at exit: As above (approx $228.0m TL, $198.7m Mezz)
• Entry equity: $808.8m

4. Underwriting Risks & Downside Protection Levers

Key Risks

1. Contract Concentration: Loss of a major data center client materially impacts revenue.
2. Tech Disruption: Shift in cooling technology (e.g., liquid cooling) could reduce demand for traditional HVAC services.
3. Labor Shortage/Inflation: Tight labor market or wage increases could compress margins.
4. Slower End-market Growth: Slower data center buildout or macro downturn reduces recurring revenue growth.
5. Execution Risk: Failure to improve margins (e.g., via cost initiatives or upsell) limits deleveraging and value creation.

Downside Protection Levers

1. Strong Recurring Contracts: Focus on high-renewal, long-term customer agreements for base cash flow.
2. Cost Flexibility: Variable cost structure allows for expense reduction in downturns.
3. Covenant-lite Structure: Negotiate flexible covenants to avoid default in a downturn, preserving optionality.
4. Diversification: Expand customer base and service lines to reduce concentration risk.
5. Capex Deferral: Ability to defer non-critical capex to preserve cash in tough periods.

Summary Table (FY2026–FY2030)

FY	Revenue	EBITDA	Capex	ΔNWC	Taxes	FCF after Debt Service	TL End Bal	Mezz End Bal
2026	972.0	136.1	29.2	0.36	17.8	19.14	456.1	183.6
2027	1,039.0	155.8	31.2	0.34	22.1	32.14	419.4	187.3

Let's proceed step-by-step. I'll summarize the key calculations and create the simplified table, then move to IRR/MOIC, sensitivity, and risks.

---

Initial Deal Assumptions Recap

• Entry EBITDA FY2025: $120m
• Entry EV: 12.0x EBITDA = 12.0 * 120 = $1,440m
• Transaction fees: 2.0% * $1,440m = $28.8m (paid from equity)
• Leverage at close:
  • Term Loan: 4.0x EBITDA = 4.0 * 120 = $480m
  • Mezzanine: 1.5x EBITDA = 1.5 * 120 = $180m
  • Equity: EV - debt - fees = 1,440 - 480 - 180 - 28.8 ≈ $751.2m

---

Step 1: Year-by-Year Financials (FY2026–FY2030)

Key assumptions:

• Revenue grows as per schedule
• EBITDA margin improves as per schedule
• Capex: 3% of revenue
• ΔNWC: 0.5% of incremental revenue
• Interest:
  • Term Loan: 9% cash interest, amortizing 1% annually
  • Mezzanine: 12% cash interest + 2% PIK
• Taxes: 25% on (EBITDA - cash interest)

---

Calculations for FY2026 (example, then summarized)

FY2025 (base):

• Revenue = $900m
• EBITDA = $120m
• EBITDA margin = 13.3%

---

Projected Revenue & EBITDA:

Year	Revenue	EBITDA Margin	EBITDA
FY2026	900 * 1.08 = $972m	14.0%	972 * 14% = $136m
FY2027	972 * 1.07 = $1,039m	15.0%	1,039 * 15% = $156m
FY2028	1,039 * 1.06 = $1,101m	16.0%	1,101 * 16% = $176m
FY2029	1,101 * 1.05 = $1,155m	16.5%	1,155 * 16.5% = $190.7m
FY2030	1,155 * 1.05 = $1,213m	17.0%	1,213 * 17% = $206m

---

Interest & Taxes (simplified):

• Term Loan interest: 9% * outstanding debt (initially $480m, amortizing 1% annually)
• Mezzanine interest: 12% cash + 2% PIK (accrues to principal, paid at exit)

---

Debt Amortization & Balance:

Year	Term Loan	Mezzanine	Total Debt	Interest (Term)	Interest (Mezz)
FY2026	480 - 4.8 = 475.2	180	655.2	9% * 480 = $43.2m	12% * 180 = $21.6m + PIK (adds to principal)
FY2027	475.2 - 4.75 = 470.45	180	650.45	9% * 475.2 ≈ $42.8m	12% * 180 = $21.6m + PIK
FY2028	470.45 - 4.70 = 465.75	180	645.75	9% * 470.45 ≈ $42.3m	same
FY2029	465.75 - 4.66 = 461.09	180	641.09	9% * 465.75 ≈ $41.9m	same
FY2030	461.09 - 4.61 = 456.48	180	636.48	9% * 461.09 ≈ $41.5m	same

Note: PIK accumulates, so principal increases by 2% PIK each year. For simplification, assume the mezzanine principal remains at $180m (or slightly increases due to PIK), but for simplicity, we'll assume full repayment at exit.

---

Tax Calculation:

EBITDA - cash interest:

• FY2026: $136m - $43.2m ≈ $92.8m
• Taxes: 25% * max(0, EBITDA - interest)
• FY2026 taxes: 25% * $92.8m ≈ $23.2m

Similarly for subsequent years.

---

Free Cash Flow (FCF):

[ \text{FCF} = EBITDA - Taxes - Capex - ΔNWC - Interest ]

• Capex: 3% of revenue
• ΔNWC: 0.5% of revenue increase from prior year

---

Summary of Year-End Debt & FCF:

Year	Revenue	EBITDA	Interest (Term)	Taxes	Capex	ΔNWC	FCF	End of Year Debt
FY2026	$972m	$136m	$43.2m	~$23m	$29.2m	~$4.86m	calculate	~$470m (after debt paydown)
FY2027	$1,039m	$156m	~$42.8m	~$25m	$31.2m	~$4.35m	...	...

And so forth, reducing debt with excess FCF.

---

Exit at FY2030:

• EBITDA = $206m
• Exit multiple: 10.5x → EV = 10.5 * 206 ≈ $2,163m
• Exit fees: 1% * EV = $21.6m
• Repay mezzanine principal + PIK (assumed fully repaid)
• Remaining debt paid off from sale proceeds
• Equity proceeds = EV - remaining debt - exit fees

---

Step 2: IRR and MOIC

• Initial equity invested: ~$751.2m + $28.8m fees = ~$780m
• Exit proceeds: Approximate based on remaining debt + equity value
• Estimate equity IRR: Assuming debt amortization and cash flows, approximate IRR ~ 18-22%
• MOIC: (Exit Equity Value / Initial Equity) ≈ 2.0x–2.2x depending on debt repayment and valuation.

---

Step 3: Sensitivity Table

Exit Multiple / EBITDA Margin	16%	17%	18%
9.5x	IRR ~ 15%	16%	17%
10.5x	IRR ~ 18%	19%	20%
11.5x	IRR ~ 21%	22%	23%

(Approximate, based on valuation and cash flow sensitivity)

---

Step 4: Risks & Downside Protection

Risks:

1. Revenue decline or margin compression.
2. Increased interest rates or refinancing risk.
3. Customer concentration or loss of large contracts.
4. Disruption in data center HVAC demand.
5. Rising operating costs or Capex overruns.

Protection levers:

1. Rigid customer contracts with renewal clauses.
2. Hedging interest rate exposure.
3. Diversification of customer base.
4. Cost control initiatives.
5. Strong management oversight and operational improvements.

---

Summary:
This simplified model indicates a strong potential IRR (~18–22%) driven by EBITDA growth and multiple expansion, with mitigants in place for key risks. Actual detailed modeling would refine debt amortization, tax impacts, and cash flows, but this framework provides a solid foundation for the investment committee review.

• Customer concentration in hyperscalers
• High leverage sensitivity to interest rate shifts
• Technology shifts reducing HVAC requirements per MW

Downside protection levers

• Accelerated cost takeout program within first 12 months
• Renegotiation of long‑term service contracts with escalators
• Add‑on acquisitions for cross‑sell and scale efficiencies
• Capex prioritization and deferral
• Early refinancing to reduce cash interest burden

1) Projected cash flows & debt (FY2026–FY2030, $m)
(“FCF after debt service” = after interest, taxes, capex, ΔNWC, mandatory amort; applied to optional TL paydown)

Year	Revenue	EBITDA	TL Cash Int.	Mezz Cash Int.	Cash Taxes	Capex	ΔNWC	FCF after debt service	End TL Bal.	End Mezz Bal. (incl. PIK)

2028	1,102.4	176.4	37.6	22.5	29.1	33.1	0.31	49.0	364.1	191.0
2029	1,157.5	190.0	32.8	22.9	33.6	34.7	0.28	60.9	298.3	194.8
2030	1,215.4	206.6	26.8	23.4	39.1	36.5	0.29	75.7	217.8	198.7

• Mandatory TL amort: $4.8m/yr (included in FCF calc).
• Optional TL paydown each year uses FCF after debt service.
• Mezz PIK 2%/yr accrues to principal (balances shown above).

Exit (end FY2030, base case)

• FY2030 EBITDA: $206.6m; Exit @ 10.5x = EV $2,169.5m
• Exit fee 1% EV: $21.7m
• Net debt repaid: TL $217.8m + Mezz $198.7m = $416.5m
• Equity proceeds: $2,169.5 – $21.7 – $416.5 ≈ $1,731.3m
• Equity invested (incl. fees): $808.8m
• MOIC ≈ 2.14x; 5-yr IRR ≈ 16.4%

2) Equity IRR/MOIC (base): MOIC 2.14x; IRR ~16.4%.

**3) Sensitivity:

1) Simplified FY2026–FY2030 Operating & Debt Table

(Figures in $m; ΔNWC is outflow; “FCF after debt service” = EBITDA – cash interest – cash taxes – capex – ΔNWC. Optional Term Loan paydown uses remaining FCF after required 1% amortization.)

FY	Revenue	EBITDA	Term Interest	Mezz Interest	Cash Taxes	Capex	ΔNWC	FCF after debt service	Term Loan amortized (1%)	Optional Term paydown	Ending Term Debt	Ending Mezz Debt (incl. PIK)
2026	972.0	136.1	43.2	21.6	22.0	29.2	3.6	16.6	4.8	11.8	463.4	192.5
2027	1,040.0	156.0	41.7	23.1	27.3	31.2	3.4	29.3	4.8	24.5	434.1	204.4
2028	1,102.4	176.4	39.1	24.5	32.2	33.1	3.1	44.5	4.8	39.7	389.6	217.9
2029	1,157.5	191.0	35.1	26.1	35.7	34.7	2.7	52.4	4.8	47.6	337.2	232.8
2030	1,215.3	206.6	30.3	29.7	37.7	36.5	2.9	66.6	4.8	61.8	270.6	249.9

Key notes on the table:

• EBITDA derived from revenue × margin.
• Taxes = 25% × max(0, EBITDA – total cash interest).
• Optional Term Loan paydown equals remaining FCF after deducting the 1% mandatory amortization (4.8) and is applied entirely to Term Loan.
• Mezzanine balance grows by 2% PIK each year.

2) Exit & Investment Returns

• FY2030 EBITDA: $206.6m.
• Exit EV = 10.5 × 206.6 = $2,167m.
• Exit fees = 1% × 2,167 = $21.7m paid at exit.
• Net proceeds before debt repay = $2,167 – 21.7 = $2,145.3m.
• Debt repay at exit: Term = $270.6m; Mezz = $249.9m → total $520.5m.
• Equity proceeds = $2,145.3 – $520.5 = $1,624.8m.
• Initial Equity Invested (includes transaction fees): $808.8m.
• Holding period ~5 years.

Equity Returns

• MOIC = $1,624.8 / $808.8 ≈ 2.01x
• IRR: solve (1.0 + IRR)^5 = MOIC ⇒ IRR ≈ 15.1%

3) Sensitivity: Equity IRR vs Exit Multiple & FY2030 EBITDA Margin

	Exit Multiple 9.5x	10.5x (Base)	11.5x
FY2030 EBITDA 16.0%	12.5%	13.8%	15.2%
FY2030 EBITDA 17.0%	13.5%	14.9%	16.3%
FY2030 EBITDA 18.0%	14.5%	15.9%	17.3%

(Exit EBITDA margin tweaks revenue and EBITDA accordingly, keeping other assumptions constant; exit value scales with margin and multiple.)

4) Risks

1. Customer concentration – data-center clients may renegotiate or switch due to single-supplier dependency.
2. Inflation in labor costs – recurring service model sensitive to technician wage pressure, squeezing margins.
3. Technology obsolescence – monitoring solutions may fall behind newer automation tools, reducing renewal rates.
4. High leverage – 5.5x total leverage leaves limited cushion for revenue/margin dips before debt covenants strain cash taxes & capex coverage.
5. Interest rate volatility – floating-term rates (if repriced) would increase cash interest, further burdening FCF.

5) Downside Protection Levers

1. Dense cash conversion – aggressive working capital management to minimize ΔNWC beyond the 0.5% assumption.
2. Capex discipline – maintaining capex at or below 3% of revenue to preserve FCF for debt paydown.
3. Accelerated paydown – optional prepayments deployed whenever FCF allows to reduce term balance faster.
4. Pricing adjustments – annual escalators or CPI indexation in contracts to protect margins.
5. Service-level diversification – expanding into complementary predictive-maintenance offerings to offset base-service risks.

Rows = Exit EBITDA Margin (FY2030)
Columns = Exit Multiple

Exit Margin	9.5x	10.5x	11.5x
16%	~12.8%	~14.6%	~16.3%
17% (Base)	~14.6%	16.5%	~18.3%
18%	~16.3%	~18.4%	~20.5%

(Assumes same leverage path; EBITDA flexed via margin only.)

---

4) Key Underwriting Risks

1. Customer concentration among hyperscale data center operators.
2. Margin execution risk from labor inflation and technician availability.
3. Technology displacement (AI-based predictive monitoring in-house by customers).
4. Leverage sensitivity with meaningful mezz + PIK compounding.
5. Exit multiple compression in infrastructure / services valuations.

---

5) Downside Protection Levers

1. Tighter covenants & excess cash sweep to accelerate de-levering.
2. Pricing escalators and CPI-linked clauses in service contracts.
3. OpEx flexibility via subcontracting and variable labor mix.
4. Capex deferral in non-critical monitoring upgrades.
5. Early mezz refinance once leverage <4.0x to reduce cash + PIK drag.

---

Bottom line:
A defensible, cash-generative LBO with mid‑teens base‑case IRR, strong de‑levering, and meaningful upside from margin expansion and multiple stability.
