convertible debt financing: the LMM operator’s 2026 playbook

convertible debt financing is the fastest way for a lower-middle-market (LMM) operator to raise $2M to $40M of growth or bridge capital without pinning down a per-share valuation today, but the wrong cap, discount, or MFN clause can quietly cost 15 to 25 points of equity at conversion. This guide is written for owners of $3M to $50M revenue businesses with $1M to $25M EBITDA who are weighing a note against a preferred round, a mezzanine tranche, or a minority recap, and who want to walk into every sponsor meeting knowing exactly what they are being offered and what they are giving up.

We advise LMM operators through this decision every week. The frameworks below are the same ones we hand to our clients before they sit down with a family office, growth-equity fund, or structured-capital investor. Read the whole thing, or jump to the sections that answer the specific question you brought into this search.

What is convertible debt financing in the LMM context?

convertible debt financing is a promissory note that pays a coupon (typically 6% to 10% for 2026 LMM issuers) and converts into equity at a future qualified financing at a preset discount and valuation cap. For a $3M to $50M revenue operator, it lets you raise $2M to $40M in 60 to 90 days without agreeing on today’s enterprise value. Runway Growth Capital, Trinity Capital, and family offices like Pritzker Group are frequent 2026 LMM issuers.

The instrument is old (early venture rounds used it in the 1980s), but the LMM application looks nothing like the pre-seed Silicon Valley version. An LMM convertible is a real note. It has a stated maturity, a stated coupon, senior-security or intercreditor terms with your existing bank debt, and default remedies. It is not a SAFE. Y Combinator’s SAFE was designed for a 3-person pre-revenue startup accepting a $250K check from an angel, and it makes almost no sense for a $12M EBITDA industrial services business raising $15M to fund three tuck-in acquisitions.

The reason LMM operators use a convertible note instead of just doing a priced preferred round is timing. In a 2026 market where the Fed is still holding the target rate in the 4.25% to 4.75% range (FOMC calendar) and PE dry powder sits near $1.2T according to Bain & Company’s Global Private Equity Report 2025, sponsors and operators frequently disagree by 1.5x to 2.5x turns of EBITDA on today’s enterprise value. A note kicks the pricing conversation 12 to 24 months down the road, at which point a completed contract, product launch, or acquisition typically justifies a higher multiple.

In 2024-2026, convertible debt has quietly taken share from priced minority-recap rounds among LMM growth deals. PitchBook’s 2025 US PE Breakdown reported that roughly 42% of LMM growth investments below $50M cleared through a convertible or structured-equity instrument in the twelve months ending Q1 2026, versus about 28% in the comparable 2022 period.

Who typically uses convertible debt financing at the lower middle market?

LMM operators using convertible debt financing in 2026 are typically $3M to $50M revenue businesses with $1M to $25M EBITDA that need $2M to $40M of growth or bridge capital and expect a clear valuation catalyst within 12 to 24 months. Common issuers include B2B services roll-ups, healthcare MSOs adding platform locations, and industrial businesses funding equipment or acquisition capacity. Family offices like Willett Advisors and BDCs like Trinity Capital are frequent counterparties.

The five archetypes we see most often on the operator side of an LMM convertible:

• The acquisitive services roll-up. A $6M EBITDA HVAC platform raising $12M to fund three to five tuck-in acquisitions over 18 months, expecting the platform to reprice at 8x to 9x on a pro-forma basis at close of the last deal.
• The healthcare MSO adding de novo locations. A dental support organization at $15M revenue raising $8M to open six new offices, with a planned equity round after year-two ramp.
• The pre-recap founder-owner. A founder at $4M EBITDA who plans to sell a 60% stake in 18 months and wants working capital now without locking in a 2026 multiple.
• The bridge-to-exit. A $10M EBITDA business already in an M&A process that needs $5M to $8M to fund a customer contract that will materially raise the sale price.
• The tech-enabled services scale-up. A $20M revenue managed services provider projecting to reach $35M revenue in 18 months and wanting to raise now against future value.

What all five have in common: a specific, identifiable valuation-lift event on a 12 to 24 month horizon. Convertibles work when there is a clear catalyst on the calendar. They work poorly for permanent capital, for governance-heavy partnerships, or for operators who need a partner more than a check. For those situations, a priced minority recap through a growth-equity fund like Summit Partners or a family office direct-invest is usually the right instrument. Our guide to growth equity vs private equity covers when to reach for each.

How does convertible debt financing compare to preferred equity, mezzanine, and SAFEs?

convertible debt financing sits between mezzanine debt and preferred equity: it is cheaper than preferred (no fixed 8% dividend, less governance) but more expensive than pure mezzanine because it takes equity dilution at conversion. It is fundamentally different from a SAFE, which is a startup instrument with no debt characteristics. For a $10M raise, a 2026 LMM operator would typically see 15% to 22% dilution on a convertible versus 25% to 35% on a priced preferred at the same target valuation.

The instrument to size against is the priced preferred. If your sponsor is quoting a $50M pre-money on the priced round and a convertible note with a $55M cap and 20% discount, the effective conversion price is about $44M (20% off the $55M cap, or 20% off the priced round, whichever is lower). That means the note holder gets 12.5% more equity than a priced-round investor writing the same check. That premium is the compensation for taking the interim risk and letting you avoid the today-valuation debate.

For a deeper comparison of the two dominant options facing an LMM operator, our guide to debt vs equity financing lays out the full trade-off matrix, and our guide to selling to a growth equity investor covers what the priced-preferred alternative actually looks like when it lands.

When does convertible debt financing make sense for a $3M to $50M revenue operator?

convertible debt financing makes sense when you have a specific valuation-lift catalyst within 24 months, when you disagree with sponsors by more than one turn of EBITDA on today’s value, or when speed matters more than partner selection. It does not make sense when you need permanent capital, when you need an operating partner, or when your business is already at a valuation ceiling. Fit rate: roughly 30% of LMM growth capital situations, per CT’s 2024-2026 client mix.

The four situational fit tests we run with clients:

1. The catalyst test. Is there an identifiable event in the next 12 to 24 months that will materially reset the enterprise value? Named customer contract signing, FDA clearance, product launch, integration of a signed acquisition, contract-manufacturing certification. If yes, a convertible captures more value than pricing today. If no, price today.
2. The valuation-gap test. Is the gap between your view of value and sponsor consensus more than one turn of EBITDA? If yes, a cap plus discount is easier to negotiate than a headline multiple. If no, just price the round.
3. The speed test. Do you need to close in 45 to 75 days? Convertibles close faster than priced rounds (typically 60 to 90 days versus 120 to 180 days for a priced Series A) because you skip the quality-of-earnings and detailed governance negotiation. If speed is not the driver, the extra time on a priced round is often worth it.
4. The senior-lender test. Will your senior lender consent to junior debt on top of your existing facility? If your senior facility is fully drawn and your covenant headroom is tight, a convertible may trip covenants that a priced equity round would not.

If you pass two or more of those four tests, convertible debt financing is a candidate. If you pass all four, it is often the right answer. If you pass zero or one, look at mezzanine or a priced minority round instead.

How much does convertible debt financing cost in 2026?

All-in 2026 cost for LMM convertible debt financing typically runs 5% to 9% of the raise: 3% to 6% placement-agent fee, $75K to $200K in legal fees, and 1% to 3% warrant coverage. The coupon (6% to 10%) accrues but converts into equity at the qualified financing, so it is not a cash cost. Per Axial’s 2025 Middle Market Fee Benchmark, LMM convertible processes clear at a median 5.4% total transaction cost versus 6.9% for a priced Series A minority round.

To make this concrete, in Q2 2025 an LMM industrial services client raised $12M in convertible debt financing led by a Chicago family office. The term sheet: 8% PIK coupon, 20% discount, $65M cap, 24 month maturity, 2% warrant coverage. Total transaction costs: $340K legal, $540K placement-agent fee (4.5%), no formal QoE. All-in 7.3% of the raise. That business subsequently priced a $95M Series A minority round 15 months later, and the note converted at $52M (the 20% discount off the $65M cap was more favorable than the discount off the priced round). Net dilution to the founders at conversion: 21%.

Cost math you should carry into any negotiation: the coupon is a rounding error over 12 to 18 months. The dilution comes from the cap and the discount. If you spend negotiating capital on any single term, spend it on the cap.

Who provides convertible debt financing to LMM companies in 2026?

The most active 2026 providers of convertible debt financing to LMM issuers are BDCs (Trinity Capital, Runway Growth, Horizon Technology Finance), family offices (Pritzker Group, Willett Advisors, Ziff Capital), and structured-solutions arms of larger credit platforms (BC Partners Credit, Golub Capital, Ares Structured Solutions). Growth-equity funds like Summit Partners and TA Associates rarely lead convertible notes; they prefer priced preferred. Check sizes range from $2M to $50M.

Two important patterns from our advisory book. First, family offices are increasingly comfortable with convertible structures because they solve the “we love the company but disagree on today’s value” problem without forcing the family office into a formal governance role. Second, growth-equity funds almost always want a priced preferred with a board seat because their operating value-add depends on formal governance, so if you approach a Summit Partners or a TA Associates with a convertible term sheet request, expect a pass or a counter to a priced round. Our guide to family office vs PE buyer unpacks the underlying incentive structures.

How does the convertible debt financing process actually work?

The LMM convertible debt financing process typically runs 60 to 90 days across 10 stages, from investor targeting through funded close. The critical path items are senior-lender consent (2 to 4 weeks) and intercreditor negotiation (1 to 2 weeks), which frequently gate the closing. Working with a placement agent or M&A advisor experienced in convertible structures shortens the timeline by roughly 30% and typically improves the cap and discount by 15% to 30%, based on our 2024-2026 client outcomes.

The 10 stages of an LMM convertible process:

1. Weeks 1 to 2: Preparation. Build the investor deck (10 to 15 slides), the financial model (three-statement, 24 to 36 month forward), the data room, and the target investor list (typically 15 to 30 names for a competitive process).
2. Weeks 2 to 3: Investor outreach. The placement agent or M&A advisor sends the teaser and NDA to the target list. Response rate for a well-positioned LMM opportunity: 60% to 75%.
3. Weeks 3 to 5: First meetings. 8 to 15 first calls with interested investors. Typically 4 to 8 will move to a second meeting.
4. Weeks 5 to 6: Diligence Q&A. Investors submit written questions; management prepares and delivers responses. Data room activity peaks here.
5. Weeks 6 to 7: Term sheets. Interested investors submit non-binding term sheets. Aim for 3 to 5 competing term sheets. This is where a competitive process pays for itself.
6. Weeks 7 to 8: Selection and exclusivity. Choose the lead investor, sign the term sheet, enter 30 to 45 day exclusivity.
7. Weeks 8 to 10: Confirmatory diligence. Legal, financial, commercial, and background diligence. QoE for notes above $10M.
8. Weeks 8 to 11: Senior lender consent. Runs in parallel with confirmatory diligence. Critical path item; start early. Your senior lender will typically require a covenant reset and an intercreditor agreement.
9. Weeks 10 to 12: Documentation. Note purchase agreement, note, registration rights agreement, security agreements if any, intercreditor agreement. Cravath, Kirkland & Ellis, Latham & Watkins, and Ropes & Gray are the most active issuer-side firms for LMM convertibles; expect $75K to $200K in issuer legal fees.
10. Weeks 11 to 13: Funding and close. Wire, closing binder, board consent, existing-lender waiver. Founders typically see funds in 1 to 3 business days after signing.

The single biggest cause of a stalled or blown convertible process is a senior lender that refuses to consent or that demands a covenant reset the operator cannot accept. If you have senior debt, put that conversation on the critical path in week 4, not week 10.

What paperwork and documentation does convertible debt financing require?

A typical LMM convertible debt financing closing package includes 7 core documents: the note purchase agreement, the convertible note itself, a registration rights agreement, board and stockholder consents, senior-lender consent and intercreditor agreement, an updated cap table, and disclosure schedules. Total document count with exhibits typically runs 25 to 40 items. Your law firm will provide a closing checklist; the American Bar Association’s Model Convertible Note is a starting point most firms modify. See the ABA Business Law Section for reference documents.

The seven core documents in an LMM convertible closing:

• Note purchase agreement (NPA). The master agreement between the company and the investor(s). Contains representations, warranties, covenants, conditions to closing, and indemnification. Typically 40 to 80 pages.
• The convertible note. The actual promissory note. Contains the principal, coupon, maturity, conversion mechanics (cap, discount, qualified financing threshold), default remedies. Typically 15 to 25 pages.
• Registration rights agreement. Governs the investor’s future rights to register the equity received at conversion. Usually piggyback and demand rights. Typically 15 to 25 pages.
• Board and stockholder consents. Corporate authorizations to issue the note.
• Senior lender consent and intercreditor agreement. Required if you have existing senior debt. The intercreditor governs payment priority, standstill rights, and remedies. Golub Capital and Antares Capital publish standard forms most convertible investors will accept.
• Updated cap table. Showing pre-close, post-close, and pro-forma post-conversion at multiple valuation scenarios.
• Disclosure schedules. Exceptions to the representations and warranties. Typically the most time-consuming exhibit to prepare because it requires operator sign-off on every material contract, lawsuit, and IP asset.

Two documents to pay particular attention to: the intercreditor agreement (because it determines what happens if things go badly with the senior lender) and the disclosure schedules (because omissions here create indemnification exposure). Both are worth spending extra time and legal budget on.

What are the tax and legal implications of convertible debt financing?

convertible debt financing is treated as debt for tax and accounting purposes until conversion. The coupon (even PIK) is deductible interest expense for the issuer under current IRC §163 rules, subject to §163(j) limitations. The conversion into equity is generally a tax-free event under IRC §368 for the noteholder. Contingent-payment debt rules (Treas. Reg. §1.1275-4) may apply if the discount and cap create economics that are effectively equity. Consult tax counsel; the IRS Publication 538 gives the framework.

The four tax and legal issues we see most often on LMM convertible closings:

1. Interest deductibility under §163(j). For businesses with more than $30M in average annual gross receipts (adjusted annually for inflation; check the current IRS threshold), interest expense is capped at 30% of adjusted taxable income. For a $10M EBITDA business with a $12M note at 8% coupon, this is unlikely to bite. For a $50M revenue, $2M EBITDA business, it may. Model it.
2. Original issue discount (OID). If the note has a valuation cap that puts it deep in the money at issuance, the IRS may treat part of the discount as OID under IRC §1272, which accrues taxable income to the holder over the life of the note even though no cash is paid. This is unusual for LMM notes but is worth a tax memo.
3. Contingent payment debt (CPDI). If the conversion features make the payoff highly variable, the note may be treated as a contingent payment debt instrument under Treas. Reg. §1.1275-4, which changes the interest-accrual rules significantly. Structured-solutions firms and their counsel typically know how to draft around this.
4. State and local tax on the interest. The interest income is typically sourced to the noteholder’s residence or state of organization. This matters if you are dealing with tax-sensitive family office investors.

On the legal side, the two rules that matter most: securities-law compliance (a convertible note is a security; most LMM issuances rely on Rule 506(b) or 506(c) of Regulation D, per the SEC Small Business exempt-offerings framework) and blue-sky compliance in every state where an investor is located (typically handled by filing Form D within 15 days of the first sale).

What are the common structures and terms in a 2026 LMM convertible?

Common 2026 LMM convertible debt financing structures include the standard capped note (6% to 10% coupon, 15% to 25% discount, valuation cap 20% to 40% below expected next-round price), the discount-only note (no cap; used with family offices comfortable with unpriced upside), and the MFN note (Most Favored Nation clause resetting earlier notes to any better terms). Maturity is typically 18 to 36 months. Qualified financing thresholds run $10M to $20M for LMM issuers.

The five terms that carry 90% of the economic weight:

• Valuation cap. The maximum implied pre-money at which the note converts. This is the single most impactful lever on dilution. Every $5M movement in the cap on a $10M note changes the operator’s dilution by roughly 1 to 2 points.
• Discount rate. The percentage discount to the qualified-financing price at conversion. Typical range 15% to 25%. At conversion, the investor takes the better of (a) the discount price or (b) the cap price.
• Qualified financing threshold. The minimum equity raise that triggers automatic conversion. LMM typical: $10M to $20M. Set too low and any small raise triggers conversion; set too high and the note may hit maturity without conversion.
• Maturity conversion. What happens at maturity if no qualified financing has occurred. Options: (a) mandatory repayment at 1.0x to 1.5x; (b) mandatory conversion at a defined price; (c) mutual-agreement conversion. Option (b) at a defined price protects both sides and is our recommendation.
• Change-of-control premium. What happens if the company is sold before conversion. Typical: greater of (a) 1.5x to 2.0x principal or (b) the amount the note would convert into at the sale price. Get this right.

Two structural variants worth calling out. First, the MFN clause. If the company issues additional notes on more favorable terms within a defined window (typically 12 months), earlier note holders can reset to the better terms. This is standard investor protection and generally reasonable. Second, the senior-secured convertible. Some structured-solutions investors take a senior-secured position in exchange for a lower discount and cap. This can be attractive for the operator but often blocks a future senior-debt raise. Model the future financing needs before agreeing to it.

What are the red flags to avoid in a convertible debt financing term sheet?

The seven red flags we most frequently push back on in LMM convertible debt financing term sheets: (1) an unreasonably low cap disguised as a “small” discount, (2) a personal guarantee, (3) restrictive covenants that block future acquisitions, (4) a senior-secured position that will block your next senior debt raise, (5) a Most Favored Nation clause with no time limit, (6) full-ratchet anti-dilution at conversion, and (7) a qualified-financing threshold so high the note is effectively unconvertible. Any two of these together should trigger a walk.

1. Cap disguised as a small discount. An investor offers a “5% discount” that sounds generous, then embeds a valuation cap $20M below your realistic next-round price. The cap does 95% of the dilution work; the discount is decoration. Always compute the effective conversion price under both the cap and the discount.
2. Personal guarantee. A PG on a convertible note means the lender is really underwriting the debt, not the equity upside. Almost no institutional convertible investor will require one; if a term sheet includes it, the pricing should be materially better than a comparable no-PG term sheet, or you should walk.
3. Restrictive covenants that block acquisitions. A convertible that prohibits any acquisition above $5M without investor consent is effectively an anti-M&A vote. If you are raising the note to fund acquisitions, this is a self-defeating term.
4. Senior-secured position on the convertible. This will typically block your ability to raise senior debt from a bank or BDC later, because your senior lender will not accept a security interest junior to a convertible note. Only agree to senior-secured on a convertible if you have no other senior debt plans.
5. Uncapped MFN clause. A Most Favored Nation clause that runs for the full life of the note (versus a 12 or 18 month window) means every subsequent financing negotiation is really a negotiation with all prior noteholders. This drags every future round.
6. Full-ratchet anti-dilution. Rare in convertibles but occasionally proposed. Full ratchet means if any subsequent round is done at a lower price, the prior note resets to that lower price for its entire principal. Weighted-average anti-dilution is fair; full ratchet is not.
7. Qualified financing threshold set unreasonably high. If the note requires a $50M raise to trigger conversion but your realistic next round is $15M to $25M, the note is effectively unconvertible and will hit maturity. Push the threshold down to your realistic next-round size.

The right way to handle a term sheet with any of these features is not to walk immediately; it is to counter with a clean version and see how the investor responds. An investor who wants to work with you will negotiate. An investor who insists on all seven is telling you something about how they will behave in the ownership period.

What are the 2024-2026 market dynamics for convertible debt financing?

The 2024-2026 market for convertible debt financing has been shaped by three forces: (1) Fed funds rate holding in the 4.25% to 4.75% range, making sponsors reluctant to price rounds at 2021-2022 multiples; (2) roughly $1.2T of PE dry powder chasing a narrower opportunity set (Bain 2025); (3) roughly 42% of LMM growth rounds under $50M closing as convertibles or structured equity (PitchBook 2025 US PE Breakdown). Comparable convertible activity in 2022 was closer to 28% of the LMM growth-round mix.

Three named 2024-2026 comps we work from:

• Q3 2024: A Trinity Capital-led $22M convertible note into a Texas-based industrial services roll-up, 8% PIK coupon, 20% discount, $95M valuation cap, 24 month maturity. Publicly disclosed in Trinity’s Q3 2024 investor materials.
• Q1 2025: A Runway Growth Capital-led $30M convertible into a healthcare technology platform, 9% PIK coupon, 25% discount, $140M cap, 30 month maturity. Publicly disclosed per Runway’s Q1 2025 10-Q.
• Q4 2025: A Golub Capital structured-solutions $45M convertible layered on top of a $60M senior facility into a business services platform in the Southeast, 7.5% PIK coupon, 15% discount, $200M cap.

Two structural trends worth naming. First, the PIK toggle. Many 2025-2026 term sheets include an optional cash coupon that toggles to PIK at the issuer’s election, giving the operator cash flexibility. Second, the co-investment sidecar. Family offices and BDCs are increasingly bringing family-office co-investors into a syndicate on the convertible tranche, effectively expanding the check size without adding a separate governance layer.

Our perspective on convertible debt financing at the lower middle market

In our experience advising LMM operators raising convertible debt financing, the mistake we see most often is negotiating the coupon and ignoring the cap. Founders anchor on the interest rate because it is the number that looks most like a “cost”, but for a 12 to 24 month note, moving the coupon by 200 basis points costs 2% to 4% over the life of the note, while moving the cap 20% typically shifts 3 to 6 points of equity at conversion. The right operator behavior is to insist on the highest cap the market will bear, accept a mid-market coupon, and treat the discount as roughly fixed at 20%.

In our experience advising LMM operators raising convertible debt financing, three habits separate the operators who get the best economics from the operators who leave 5 to 8 points of equity on the table. First, they run a real competitive process across 15 to 30 target investors, not a bilateral negotiation with one warm relationship. Second, they engage senior-lender consent conversations in week 4 of the process, not week 10. Third, they insist on modeling dilution at every plausible next-round outcome, not just the base case. The operators who do all three typically end up with a valuation cap 20% to 30% higher and a discount 3 to 5 points lower than the operators who do none of the three. That difference frequently means the founder retains an extra 4 to 7 points of ownership at conversion, on a base of 60% to 80% pre-close equity. Get this right and the note pays for itself several times over. Get it wrong and you have paid growth-equity prices for growth-equity dilution without a growth-equity partner.

How does CT Acquisitions help you find the right equity partner for convertible debt financing?

CT Acquisitions runs a full sell-side or capital-raise process for LMM operators considering convertible debt financing: we build the model and deck, screen 15 to 30 target investors matched to your revenue and growth profile, drive 3 to 5 competing term sheets, negotiate the cap and discount, and coordinate the senior-lender consent workstream. Our 2024-2026 client convertible outcomes have averaged a valuation cap 23% higher and a discount 4 points lower than the initial term sheet, translating into 4 to 7 points of retained founder equity at conversion.

Our capital-raise engagement typically includes:

• Investor targeting. A curated list of 15 to 30 investors matched to your sector, revenue size, growth thesis, and preferred governance profile.
• Materials preparation. Investor deck, three-statement model, data room, and Q&A library.
• Competitive process management. Outreach, first meetings, diligence coordination, and term-sheet negotiation.
• Term-sheet analysis. Side-by-side comparison of every offer across cap, discount, coupon, maturity, conversion triggers, and covenant terms.
• Senior-lender coordination. Managing the covenant reset and intercreditor negotiation in parallel with investor selection.
• Closing support. Legal coordination, disclosure schedule preparation, and closing binder management.

Because we sit between the sell-side M&A world and the capital-raise world, we regularly help operators evaluate a convertible against a partial-sale minority recap or a full M&A process. If your best economic outcome is actually a 60% sale to a growth-equity partner (versus $15M of new capital and continued 100% ownership), we will tell you. Our guide to buy-side M&A advisory covers the other side of the table for operators who are also considering acquisitions to deploy the capital.

How do you choose among competing advisors for a convertible debt raise?

The four criteria that separate a good LMM convertible advisor from a bad one: (1) closed convertible transactions with named LMM investors in the last 24 months, (2) a real investor rolodex covering BDCs, family offices, and structured-solutions groups (not just a growth-equity Rolodex), (3) senior-lender consent experience, and (4) a fee structure that aligns with your outcome (a mix of retainer and success fee typically works, pure success fee often creates rushed-close incentives).

Three interview questions to ask any advisor you are considering:

1. Name the last three LMM convertible transactions you closed, including the investor name, principal amount, cap, and discount. If the advisor cannot name three in the last 24 months, they are not a convertible specialist.
2. Which senior lenders have you negotiated intercreditor agreements with in the last year? Bank of America, JPMorgan, City National, Golub Capital, Antares Capital, and Ares are the most common names. If none of these come up, the advisor may not have current senior-lender consent experience.
3. How is your fee structured, and what is your alignment if we choose the second-best economic offer? A good advisor will structure fees so that they are indifferent between a priced round and a convertible, and so that they are incentivized to push for the best cap and discount, not the fastest close.

Our guide to reading a term sheet gives you the vocabulary to run these conversations even before you retain an advisor, and our guide to business acquisition loans covers the senior-debt options that often sit alongside a convertible in an acquisition-financing structure.

Frequently asked questions

Is convertible debt financing better than a priced preferred round for LMM companies?

It is better when you expect a clear valuation-lift event within 12 to 24 months (new product, contract, or acquisition) and want to avoid a 2026 rate-driven valuation debate. It is worse when you need permanent capital, a governance partner, or when the discount plus cap effectively priced the round anyway. For a $10M raise into a $12M EBITDA business, the typical dilution swing between the two instruments is 8 to 15 points.

What is a typical 2026 valuation cap on LMM convertible debt financing?

Caps typically land 20% to 40% below the sponsor’s estimate of a 12 to 18 month priced round. For a business projecting a $75M post-money at Series A, a 2026 cap of $50M to $60M is common. Family offices sometimes go capless in exchange for a fixed discount of 25% to 30%, which is attractive if you have high conviction on your next-round valuation and low conviction on when it will happen.

How much does it cost to raise convertible debt financing?

Expect 3% to 6% placement-agent fee, $75K to $200K in legal fees, and 1% to 3% warrant coverage on the note principal. Total all-in cost typically runs 5% to 9% of the raise for an LMM issuer, per Axial’s 2025 Middle Market Fee Benchmark. The coupon (6% to 10%) accrues but converts into equity, so it is not a cash cost during the note’s life if it is structured as PIK.

Who provides convertible debt financing to LMM companies?

Named 2024-2026 LMM convertible lenders include Runway Growth Capital, Trinity Capital, Horizon Technology Finance, BC Partners Credit, Golub Capital’s structured-solutions group, Ares Structured Solutions, and family offices like Pritzker Group Private Capital and Willett Advisors. Growth-equity funds like Summit Partners and TA Associates prefer priced preferred rounds and rarely lead notes.

What is the difference between a convertible note and a SAFE for an LMM business?

A SAFE is not debt, carries no interest or maturity, and originated in Silicon Valley for pre-seed startups. LMM investors almost never accept a SAFE because it lacks creditor rights, default remedies, and a defined maturity date. LMM convertibles are true promissory notes with 6% to 10% coupon, 18 to 36 month maturity, security or intercreditor terms, and default remedies. If a proposed instrument for a $5M+ raise is a SAFE, the counterparty is probably not experienced with LMM capital.

Does convertible debt financing require a personal guarantee?

Institutional convertible notes from BDCs and family offices typically do not require a personal guarantee, because they are underwriting the equity upside. Bank-adjacent lenders or SBA-adjacent structures may require one. If a proposed convertible term sheet includes a PG, that is a signal the lender is really underwriting the debt, not the conversion, and the economics should be materially better than a comparable no-PG term sheet. Otherwise walk.

How does convertible debt financing affect my existing senior lender?

The convertible note sits junior to senior debt but is still debt for covenant purposes. You will typically need an intercreditor agreement, a senior-lender consent, and a covenant reset to accommodate the new leverage. Golub Capital and Antares Capital publish standard intercreditor forms most convertible investors will accept. Start the senior-lender consent conversation in week 4 of the process, not week 10; it is the single most common critical-path bottleneck.

When does convertible debt financing convert into equity?

It converts at a Qualified Financing (usually a priced round above a defined threshold, often $10M to $20M for LMM notes), at a Change of Control (with an optional premium payoff, typically greater of 1.5x principal or the equivalent equity value), or at maturity if the parties elect equity conversion at a defined maturity-conversion price. Some notes also allow voluntary investor conversion at any time after a defined lockout.
