Transportation Equipment Manufacturing MARC (NAICS 336)

Why MARC Fits Transportation Equipment Manufacturing

Transportation equipment suppliers (auto Tier 1s and Tier 2s, aerospace suppliers, rail-car components, marine equipment) operate under multi-year program awards with predictable WIP cycles. MARC's $5M revolving format funds the program-cycle inventory + WIP positions + bridges customer AR clearance.

**Working capital cycle**: Component purchase + WIP build → ship + AR clearance. Auto programs: 30–60 day cycles. Aerospace programs: 90–180 day cycles. Rail / marine: 60–120 day cycles. Total cycle 60–270 days depending on end market.

**Raw materials lead time**: Steel + aluminum 30–60 days; specialty composites + electronics 60–180 days; semiconductor components highly variable.

The combination of inventory turnover, raw materials exposure, and AR aging makes transportation equipment manufacturing manufacturers structurally working-capital-intensive. MARC's 20-year revolving format eliminates the recurring renewal cycle that drains CFO time at conventional bank LOCs and ABL facilities.

MARC Sizing Math for NAICS 336

**Working capital cycle**: Component purchase + WIP build → ship + AR clearance. Auto programs: 30–60 day cycles. Aerospace programs: 90–180 day cycles. Rail / marine: 60–120 day cycles. Total cycle 60–270 days depending on end market.

**Typical company size**: $5M–$100M revenue transportation equipment manufacturer

**Collateral mix**: Production equipment + tooling (45–60%), inventory + WIP (20–30%), AR (15–25%), facility (10–15%). Tooling typically customer-owned (PPAP-driven) — affects collateral value.

Worked example using mid-band figures:

| Step | Calculation | |---|---| | Annual revenue | $20M (mid-band transportation equipment manufacturer) | | Working capital outstanding | Cycle days × revenue / 365 | | Equipment collateral | ~40–55% of total collateral pool | | Inventory + WIP collateral | ~25–35% of total | | AR collateral | ~15–25% of total | | Total collateral pool | Equipment + inventory + AR + facility | | MARC sizing | Smaller of $5M cap or borrowing-base advance rates |

MARC structures advance rates by collateral type: equipment 50–75%, inventory 50%, AR 75–85%. The total borrowing base typically exceeds $5M for $20M+ revenue manufacturers — meaning the $5M cap is the binding constraint, not collateral coverage.

Underwriting Nuance for NAICS 336

PPAP (Production Part Approval Process) sign-off documentation supports new-program ramp underwriting. IATF 16949 (auto) or AS9100 (aerospace) certification mandatory for OEM customers. Multi-year program contract value drives credit profile. Customer concentration on investment-grade OEMs is acceptable at higher levels (45–60%).

Sub-sector-specialist SBA-preferred lenders carry deeper underwriting expertise than generalist 7(a) lenders. A generalist lender underwriting a transportation equipment deal often misses the industry-specific certification requirements, customer concentration norms, or collateral nuances — leading to either a wide-rate offer or a decline late in the process.

PeerSense routes transportation equipment MARC deals to SBA-preferred lenders with delegated-authority status + manufacturing-vertical expertise — same Prime + 2.75% maximum, but materially higher hit rate and faster onboarding.

Common Transportation Equipment MARC Use Cases

Program-launch WIP funding on new platform awards, tooling capex (initial tooling + production-tooling refresh), capacity expansion on volume program awards, IATF 16949 / AS9100 certification renewal, EV-program transition capex (legacy ICE → EV component capability), automation + Industry 4.0 upgrades for Tier 1 OEM compliance.

MARC's 20-year revolving format makes it uniquely suited to recurring-cycle working-capital uses. Compare to conventional 7(a) term loan (10-year amortizing — wrong format for revolving needs) or SBA 504 (real estate only — not eligible for working capital). MARC fills the structural gap.

Transportation Equipment Disqualifiers — What Blocks MARC Approval

Single program with no diversification (program-cancellation risk), no PPAP documentation, no certification (IATF 16949 / AS9100), exposure to weakening OEM (legacy ICE-only with no EV transition path), litigation / quality-issue exposure on prior program.

In addition, all-MARC blockers apply: senior UCC-1 filings on collateral by an existing lender (subordination required), active IRS tax liens (Form 14134 subordination required), state tax liens, lawsuits with material-damages exposure, OFAC compliance issues.

PeerSense pre-screens all of these blockers before any SBA-lender submission. Late-stage MARC declines damage the company's reputation in the SBA-preferred-lender market — pre-screening avoids the decline pattern.

Top Transportation Equipment Customer Profile

Auto OEMs (Ford, GM, Stellantis, Toyota, Honda, Tesla, Rivian, Lucid + Tier 1 suppliers Bosch, Magna, ZF, Aptiv, Continental), aerospace primes (Boeing, Airbus, Lockheed Martin, Northrop Grumman, Raytheon), rail-car manufacturers (Wabtec, Alstom, Siemens), marine builders, defense contractors.

The stronger the customer mix, the easier MARC underwriting. A transportation equipment manufacturer with 50% revenue from publicly-traded Fortune 500 customers prices 25–75 bps tighter than the same manufacturer with 50% revenue from small-private customers. Customer concentration on investment-grade obligors is acceptable at higher levels (35–50%+) — NAICS 336 customer concentration tolerance higher than other industries.

PeerSense pulls customer credit references + Dun & Bradstreet reports + customer AP-department references before any SBA-lender submission. Customer strength data presented up-front is a force-multiplier on rate + term negotiation.

What PeerSense Does for This Deal

PeerSense routes transportation equipment manufacturing MARC deals to SBA-preferred lenders with NAICS 336 specialty + delegated-authority status. We coordinate three workstreams:

**(1) NAICS 336 eligibility verification + MARC sizing.** Pre-run working-capital math, verify SBA size standards, confirm customer concentration tolerance, certification status, collateral mix.

**(2) SBA-preferred lender placement by transportation equipment specialty.** PeerSense maintains direct relationships with SBA-preferred lenders deeply experienced in NAICS 336 underwriting. Sub-sector-specialist routing materially affects approval rate, close timeline, and pricing.

**(3) MARC term sheet negotiation + SBA application coordination.** PeerSense reviews + negotiates rate / advance rates / reporting on the borrower's behalf. Coordinates SBA application package (Form 1919 + 413 + 912, financials, AR aging + inventory, NAICS-specific certifications) for SBA E-Tran submission.

PeerSense earns a fee at closing — paid by the borrower out of MARC loan proceeds at standard SBA borrower-paid commission. No retainers, no application fees, no upfront cost. Standard SBA placement fee 0.5–1.0% of loan amount.

If you operate a transportation equipment manufacturing manufacturer in NAICS 336 with $5M–$100M transportation equipment in revenue and need $5M revolving credit at 20-year term, share the financials + AR aging + inventory listing in the form below. PeerSense will return a MARC structure recommendation + indicative pricing within one business day.
