The buy-and-build model survived the bank retreat because its financing migrated to collateral. The platform buys, the add-on borrows, and the lender prices against the acquired assets instead of the sponsor's covenant. The result is a consolidation machine that runs on asset coverage, not bank relationships.
The Basel Endgame accelerated the migration. Regional banks that once funded mid-market leveraged transactions stepped back, and the capital that replaced them prices differently. Asset-based lenders underwrite inventory, receivables, and equipment. They do not underwrite the story.
The regulatory cycle did not end bank lending. It ended leveraged mid-market bank lending. Several large regional banks have exited middle market leveraged lending entirely since 2024, per ABF Journal, redirecting balance sheet capacity toward investment-grade relationships and fee-based advisory work.
The final Basel package softened parts of the original proposal. PwC's Capital Reform 2026 analysis concludes the package lowers capital requirements overall, reduces duplication across the framework, and improves the economics of traditional lending in certain segments. The distinction matters: plain vanilla corporate lending became cheaper, while leveraged, sponsor-backed, and asset-heavy exposures stayed capital-intensive.
The consequence is structural. Banks re-price the balance sheet toward the segments where their cost of capital beats the competition, and leveraged mid-market credit falls outside that zone. The funding gap does not disappear. It moves to lenders whose capital stack was built for it.
Asset-based lending prices the collateral, not the covenant. The lender takes a first lien on receivables, inventory, equipment, and real estate, applies advance rates, and monitors the borrowing base monthly. The borrower's equity story matters for the residual, not for the facility.
BlackRock's 2026 Private Markets Outlook identifies asset-based financing as an area of private credit where a profound increase in opportunities is expected. The driver is mechanical: as banks compress leveraged exposure, the collateral pools they once financed become available to non-bank lenders with matching underwriting infrastructure.
The underwriting difference changes deal design. A sponsor that borrows against EBITDA accepts covenant testing and enterprise risk. A sponsor that borrows against assets accepts borrowing-base discipline and reporting obligations. The second structure is less elegant and more durable, which is exactly why it survives a credit cycle intact.
The buy-and-build model consumes equity at every add-on unless the add-on borrows. Fund III capital that funds a platform purchase price cannot simultaneously fund the next four acquisitions. Asset-based financing resolves the tension.
The structure runs in sequence. The platform closes with a mix of equity and senior debt. Each add-on is acquired by a holdco that pledges the target's assets, and the acquisition facility is sized against the combined borrowing base. The fund's equity contribution per add-on drops toward the equity cushion the lender requires.
The effect compounds. Every completed add-on adds collateral to the pool, which expands the facility, which funds the next add-on. The fund preserves dry powder, the portfolio grows faster, and the returns concentrate in the equity that was never deployed.
The arbitrage is a spread between two valuations. The lender values the acquired assets at advance rates, and the market values the consolidated enterprise on earnings. The buyer captures the difference by converting asset value into earning capacity.
A distributor with owned warehouses, vehicles, and receivables trades at a multiple of EBITDA. Its assets support a borrowing base that funds the acquisition of a smaller competitor with the same collateral profile. The competitor's EBITDA consolidates into the platform, the combined borrowing base expands, and the next acquisition funds itself.
The arbitrage widens in exactly the segments banks abandoned: distribution, industrial services, healthcare services, and asset-heavy niche manufacturing. These are the mid-market segments where asset intensity is highest and bank appetite is lowest, per the ABF Journal analysis of the leveraged lending exit.
The structure fails without discipline. The borrowing base must be audited, the collateral must be controlled, and the reporting must be monthly. A sponsor that treats the facility as covenant-lite discovers the difference in the first collateral audit.
The operational requirements are the actual barrier to entry. The platform needs clean receivables aging, serialized inventory systems, and equipment registers that reconcile to the balance sheet. The lenders require it, and the add-on targets rarely have it, which is precisely why the model rewards operators who build the infrastructure.
The reporting burden becomes a moat. A target whose books cannot support a borrowing base cannot be financed this way, and a sponsor without the operating team cannot build the base. The arbitrage belongs to sponsors who combine consolidation skill with asset-level operational control.
Roials Capital structures asset-backed facilities for mid-market consolidation mandates, and this is its commercial model, not an industry statistic. The firm arranges non-dilutive capital against operating assets and balance sheet security for sponsors executing buy-and-build programs.
The model fits the market's structure. Fund III sponsors with deployment pressure, asset-heavy add-on pipelines, and equity conservation targets are the natural counterparties. The financing is a tool for industrial consolidation, never an end in itself.
The institutional read is simple. The Basel Endgame did not kill leveraged consolidation. It re-priced it, and the collateral-based version of the model now carries the economics. Sponsors who adapt the structure capture the arbitrage, and sponsors who wait for the old bank market to return wait for a market that no longer exists.
The buy-and-build arbitrage lives in the gap between asset value and enterprise value. Banks exited leveraged mid-market lending, asset-based lenders filled the gap, and the consolidation model re-priced itself around collateral. The Fund III arithmetic works because add-ons borrow against assets instead of consuming equity. The execution requirements are real, and the sponsors who meet them own the model.
