SBA MARC Loan Program: $5M Revolving Credit for Manufacturers (2026)

MARC is a revolving credit facility within the SBA 7(a) program, created specifically for manufacturers. It is not a term loan. It is not a one-time disbursement. It is a revolving line of credit — up to $5 million — where you draw funds as needed, repay them, and draw again, for the duration of the revolving period. Think of it as a corporate revolver, but purpose-built for small and mid-size manufacturers and backstopped by an SBA guarantee.

The distinction matters because most SBA 7(a) loans are term loans: you receive a lump sum, you make fixed monthly payments, and the balance declines over time. MARC operates differently. During the revolving period (typically 5 years, extendable in some structures), you can draw up to your approved credit limit, repay, and re-borrow. After the revolving period ends, the outstanding balance converts to a term loan with a fixed amortization schedule.

The program was designed to address a structural problem in manufacturing finance: manufacturers have lumpy capital needs. Raw material purchases spike before production runs. Inventory builds before shipping seasons. Equipment maintenance creates unplanned cash demands. A standard term loan forces you to borrow for peak needs and pay interest on idle capital. A revolving structure lets you match borrowing to actual cash flow cycles.

MARC eligibility is restricted to businesses classified under NAICS codes 31, 32, and 33 — the manufacturing sector. This is not a suggestion or a preference; it is a hard gate. If your primary NAICS code does not fall within these ranges, you cannot access MARC regardless of how manufacturing-adjacent your business may be.

This creates confusion for businesses that straddle manufacturing and other sectors. A company that designs products but outsources fabrication is not a manufacturer under NAICS. A company that assembles components but does not transform raw materials may or may not qualify, depending on the specific 6-digit NAICS code. The SBA uses the NAICS code registered with your business, which should match the code on your tax returns and the code your lender verifies during underwriting.

In practice, NAICS 332 (fabricated metals) and NAICS 333 (machinery) are the heaviest users of MARC because these businesses have the most volatile working capital cycles. A machine shop that bids on a $2M contract needs to purchase raw steel, aluminum, or specialty alloys upfront — sometimes 60-90 days before the customer pays. MARC was designed for exactly this cash conversion cycle.

Beyond the NAICS code, standard SBA eligibility requirements apply: the business must be for-profit, operate in the United States, meet SBA size standards for its specific NAICS code (which vary — manufacturing size standards are typically based on number of employees, not revenue, and range from 500 to 1,500 employees depending on the subsector), and the owner must have explored other financing options before seeking SBA-guaranteed credit.

The revolving mechanics of MARC are what make it genuinely different from a standard SBA term loan. Understanding how the draw, repayment, and conversion cycle works is essential before you apply.

MARC is designed for working capital and short-cycle manufacturing needs. It is not designed for long-lived assets like real estate or major equipment purchases — those are better served by SBA 504 or standard 7(a) term loans. Understanding what MARC covers (and what it does not) prevents deal structuring mistakes that can delay or kill your application.

The line between "short-term equipment" and "major capital equipment" is where underwriters exercise judgment. Tooling and fixtures that support a specific production run are typically MARC-eligible. A $500K CNC machine with a 15-year useful life is not — that belongs in an SBA 504 or conventional equipment financing structure. The general rule: if the asset has a useful life under 5 years and directly supports production cycles, it is likely MARC-eligible. If it is a long-lived capital asset, use a different program.

This is actually one of MARC's strengths: it does one thing well rather than trying to be everything. When you combine MARC with the right complementary programs — 504 for your building, equipment financing for your CNC machines, and MARC for your working capital cycles — you create a capital structure that matches each funding need to the optimal vehicle.

The SBA has implemented significant fee waivers for manufacturers in FY2026. These waivers reduce the upfront cost of SBA financing and make MARC (alongside 504 and standard 7(a)) materially cheaper for NAICS 31-33 borrowers this fiscal year. Here is what is actually waived and what is not.

Let us put real numbers on this. On a $900K MARC facility, the standard SBA guarantee fee would be approximately 2.0-3.5% of the guaranteed portion ($675K at 75% guarantee), which translates to $13,500-$23,625 in upfront fees. Under the FY2026 manufacturing waiver, that fee is eliminated entirely. On a $2M MARC facility, the guaranteed portion exceeds $950K, so the fee waiver applies to the first $950K of the guaranteed portion and standard fees apply to the remainder.

One of the most powerful — and least understood — aspects of SBA lending is that a manufacturer can use MARC, SBA 504, and standard SBA 7(a) simultaneously. There is no rule that limits you to one SBA program. The total combined SBA exposure is capped at $5M in guaranteed amounts across all programs, but within that ceiling, you can layer programs strategically.

In this example, the manufacturer uses three different financing programs for three different needs. The 504 provides fixed-rate, long-term financing for the building (with FY2026 fee waivers reducing closing costs by $30K-$50K). MARC provides revolving working capital that flexes with production cycles. Equipment financing covers long-lived production assets with terms matched to the equipment's useful life.

The key constraint is the combined SBA guarantee exposure. The 504 debenture is guaranteed by the SBA (the CDC portion), and the MARC facility carries a 75% SBA guarantee. Lenders and the SBA calculate total guaranteed exposure across all programs. If you are approaching the $5M combined guarantee ceiling, your structuring needs to be precise — which is where working with advisors who understand multi-program stacking becomes essential.

Another stacking strategy: use MARC for working capital and a standard 7(a) term loan for a business acquisition. A manufacturer buying a competitor can finance the acquisition with a $5M 7(a) term loan and simultaneously maintain a $3M MARC facility for ongoing working capital. The total SBA exposure exceeds $5M in loan amounts, but the guaranteed amounts stay within the combined ceiling if structured correctly.

MARC follows standard SBA 7(a) collateral policies, but the revolving nature of the facility creates additional underwriting considerations that borrowers need to understand.

For loans over $350,000, the SBA requires lenders to collateralize to the extent possible. This does not mean you need dollar-for-dollar collateral coverage — it means the lender must take a security interest in available business and personal assets. For manufacturers, this typically includes:

The borrowing base requirement is the piece that surprises many manufacturers. Unlike a term loan where you receive funds and make payments, a revolving facility requires ongoing reporting. Your available draw amount may be limited to a percentage of eligible receivables (typically 80%) plus a percentage of eligible inventory (typically 50% of finished goods, less for raw materials and work-in-progress). If your borrowing base shrinks — say, during a slow quarter — your available draw amount shrinks with it.

Lenders also look closely at inventory composition. Raw material inventory is generally valued at cost. Work-in-progress inventory is often discounted heavily (or excluded entirely) because its liquidation value is uncertain. Finished goods inventory is valued at the lower of cost or net realizable value. A manufacturer with $5M in total inventory might have an eligible borrowing base of only $2-3M after these adjustments.

MARC is originated through SBA-authorized lenders — you cannot apply directly with the SBA. However, not all SBA lenders are active MARC originators. The program requires specific underwriting expertise in manufacturing revolving credit, and many community banks and smaller SBA lenders do not have that capability. You want a lender who has originated MARC facilities before, understands borrowing base mechanics, and has the portfolio capacity for a $1-5M revolving commitment.

One practical tip: prepare your borrowing base certificate before you apply. A well-organized borrowing base that clearly categorizes receivables by aging bucket, inventory by type (raw, WIP, finished), and excludes ineligible items demonstrates that you understand revolving credit mechanics. Lenders underwrite borrowers, not just businesses — showing financial sophistication reduces perceived risk.

MARC usage is not evenly distributed across manufacturing. Certain subsectors have cash flow characteristics that make revolving credit essential, while others operate with less working capital volatility.

Industries with shorter cash conversion cycles — such as commercial printing (NAICS 323) or simple assembly operations — may find that a standard bank line of credit or SBA Express line serves their needs at lower cost. MARC is most valuable when the cash conversion cycle exceeds 60 days and working capital needs fluctuate by more than 30-40% between peak and trough periods.

The biggest practical obstacle to getting a MARC facility is not qualification — it is finding a lender who actively originates them. Many SBA lenders are aware of MARC in theory but have never processed one. Some banks have internal policies that limit revolving SBA exposure. Others lack the manufacturing underwriting expertise needed to evaluate borrowing bases, inventory composition, and production cycle cash flows.

PeerSense maintains a database of 899+ SBA lenders with detailed lending pattern data. We track which banks originate SBA loans across different program types, which ones have manufacturing sector concentrations, and which ones have the portfolio capacity for $1-5M revolving commitments. When a manufacturer comes to us with a MARC need, we do not send them to a lender who has never done one — we match them with banks that have active MARC programs and manufacturing underwriting teams.

We also help structure the full capital stack. A manufacturer who needs MARC for working capital might also benefit from equipment financing for production assets and SBA 504 for a facility purchase. We coordinate across all three programs to ensure the total structure makes sense — and that SBA guarantee exposure stays within limits.
