The Rise of Revenue-Based Financing in Biotech and Digital Therapeutics
Introduction
In biotech boardrooms from Boston to Basel, a new financing lexicon is taking hold. As equity markets falter and interest rates soar near 20-year highs, companies are seeking creative, revenue-based funding deals to fuel drug development and digital therapeutics platforms.
Instead of issuing shares or taking traditional loans, firms are raising capital by pledging slices of future revenues. This approach spans synthetic royalties, milestone-linked funding, and revenue-backed loans, offering non-dilutive cash today in exchange for a claim on tomorrow's sales.
The appeal is clear: biotech innovators retain control of their assets, while investors gain a contractual revenue stream decoupled from stock market swings. The result is a financing model that sits between equity, debt, and licensing—an increasingly popular middle ground in the 2023-2025 funding landscape.
Revenue-Based Funding Structures: Synthetic Royalties, Milestones, and More
Synthetic Royalty Financing
In a synthetic royalty deal, an investor provides an upfront sum (and often additional committed tranches) in return for a percentage of future product revenues, even when no traditional royalty stream exists yet.
Unlike selling an existing royalty (e.g., a university monetizing a patent royalty), a synthetic royalty creates a new obligation on future sales of a drug or digital therapeutic. The mechanism is straightforward but powerful: companies pre-sell revenue rights to assets they still fully control.
For example, in June 2025 Royalty Pharma struck a $1.25 billion synthetic royalty with Revolution Medicines, entitling it to tiered percentages of global net sales of a cancer therapy in development. The royalty rates were structured to start at 2.55% of sales up to $2 billion annually and step down to 0.6% beyond $4 billion in sales, aligning investor returns with the drug's success while capping the take from an eventual blockbuster.
This tiered structure demonstrates sophisticated financial engineering: it provides adequate returns to investors at moderate success levels while preventing excessive dilution of the company's economics at higher revenue thresholds. The step-down mechanism ensures that as the product proves itself commercially, an increasingly larger proportion of incremental revenue accrues to the company rather than the investor.
Synthetic royalties thus allow companies to raise large sums by pre-selling a slice of future revenue on a candidate product, without giving up ownership or control of the asset. Investors, for their part, price these deals based on projected cash flows and risk—often negotiating provisions to protect their downside if sales disappoint.
Milestone-Linked Funding
Many revenue-based financings are milestone-heavy, releasing funds in tranches when the company hits development or sales benchmarks. This performance-linked structure lets investors manage risk while offering companies capital at a lower overall cost.
The analytical rationale is compelling: by staging capital deployment around de-risking events, investors reduce their exposure to binary technical or regulatory failures, while companies avoid incurring obligations (or paying fees) on capital they don't yet need or haven't yet earned the right to receive.
In the Revolution Medicines deal, Royalty Pharma's $1.25 billion commitment was tranched into five draws: $250 million immediately, $250 million on positive Phase 3 data, $250 million at FDA approval, and optional tranches tied to sales milestones.
By staging funding, the investor avoids paying the full amount before critical de-risking events, and the biotech does not incur the obligation (or dilution) until it clears each hurdle. This creates an option-like payoff structure where each milestone achievement effectively exercises the next tranche option.
Smaller 2023 deals used a similar approach. Sutro Biopharma, for instance, received $140 million upfront from Blackstone and is eligible for up to $250 million more when return thresholds are met—effectively milestones based on the royalty's performance rather than development events.
In this case, Sutro sold Blackstone a 4% revenue interest in sales of a partner's vaccine; additional payments are unlocked as the product succeeds, sharing upside with Sutro.
Milestone-driven tranches have become a preferred design: they lower investors' risk profile and the issuer's cost of capital by only deploying cash as the asset proves itself. For digital therapeutics startups, one might imagine funding that arrives after hitting user or payer adoption targets—aligning cash infusion with validation of the product's revenue potential.
Revenue-Backed Loans and Royalty-Backed Debt
Not all revenue-based deals are structured as sales of a revenue stream; some take the form of loans or credit facilities secured and repaid by future revenues. These revenue-backed loans blend elements of traditional debt with revenue participation, creating hybrid instruments that adapt to product performance.
For example, in 2024 ImmunityBio secured a $300 million Revenue Interest Purchase Agreement (RIPA) from Oberland Capital, essentially a loan that will be repaid via tiered single-digit royalties on future sales of its immunotherapy, capped at a fixed multiple of the investment.
The deal provided $200 million immediately and $100 million more upon FDA approval of the therapy, with Oberland earning royalties until it achieves the agreed return cap. This structure converts what would traditionally be fixed debt service into variable payments tied directly to commercial success.
Similarly, Cara Therapeutics in 2023 raised $40 million in non-dilutive funding from Healthcare Royalty Partners by selling rights to future ex-U.S. royalties from its Korsuva™ injection. The investor's payments to Cara were tranched ($17.5M upfront, $20M on a pricing milestone in Europe, $2.5M on a Japan sales milestone), and in exchange HCR received all royalties from the drug's overseas license partners until certain limits.
Notably, HCR's total payout is capped at 2.0× its investment if reached by 2029, or 2.8× if it takes longer.
This cap functions much like a loan maturity with a time-based pricing mechanism: it ensures the investor doesn't earn an unbounded windfall, and if the royalty trickles in slowly, the higher cap compensates for the delay and reduced time value of money. The structure effectively prices risk and time: faster payback rewards the company with lower total costs, while slower commercialization increases the cost but maintains flexibility.
In essence, revenue-backed loans tie repayment to product performance—if revenues surge, the loan can be paid off early (with the cap limiting the cost to the company), whereas if revenues underperform, the company may pay longer or up to a higher total amount to satisfy the agreement.
For digital health companies with subscription models, we also see fintech-style revenue-based financing: an investor might advance, say, $5 million to a telehealth firm to be repaid via 5–10% of monthly revenues until a set amount (principal plus interest) is returned. Such deals provide flexibility—payments shrink in lean months and grow when sales grow—acting as an adaptive loan well-suited for unpredictable early revenue streams.
Financial Modeling: IRR, WACC, and NPV of Revenue Deals
To a Chartered Financial Analyst, revenue-based financings are rich in modeling nuances. Both companies and investors must assess the deal in terms of Internal Rate of Return (IRR), Net Present Value (NPV), and relative cost of capital.
The internal rate of return is the discount rate that zeroes out the NPV of the investor's cash flows (the upfront outlay vs. the stream of royalties or repayments received). Investors often structure royalty deals to target an IRR commensurate with the risk—high teens or higher for a development-stage asset, perhaps low teens for a commercial product.
The challenge in these analyses lies in projecting highly uncertain revenue streams and appropriately risk-adjusting discount rates. Unlike traditional debt with fixed schedules or equity with market-based pricing, revenue-based instruments require detailed scenario modeling across multiple dimensions: clinical success probability, regulatory approval timing, market penetration rates, competitive dynamics, and pricing pressure.
For example, consider an investor who provides $50 million to a digital therapeutics firm in exchange for 8% of future revenues until 2× ($100M) is paid back, with a small 2% royalty thereafter. If the product's sales ramp quickly and the $100M cap is hit in about 5 years, the investor achieves roughly a 15% IRR (since doubling money in 5 years is ~15% annualized). If sales are slower and the 2× return only comes after 8–9 years, the IRR falls to ~10–12%.
Most deals include features to manage this IRR range: tiered revenue share rates, caps, and step-ups. The Cara Therapeutics deal above is illustrative—by stipulating a 2.0× cap if achieved by 2029 (within ~6 years) versus 2.8× if later, the contract rewards a timely payoff (lower multiple) but allows a higher multiple if the payback drags, thereby maintaining a reasonable IRR for HCR in either case.
This time-contingent pricing mechanism is analytically elegant: it creates a convex payoff structure that partially compensates investors for延期 risk while incentivizing companies to accelerate commercialization.
From the company's perspective, the effective cost of capital can be judged by comparing the NPV of expected outflows to the cash received. If the biotech's weighted average cost of capital (WACC) is, say, 10%, and the NPV of the promised royalties (at a 10% discount rate) is comfortably below the upfront sum, the deal may be NPV-positive—a cheaper source of funds than equity dilution which might implicitly cost much more in lost future earnings.
Indeed, companies often pursue these deals when equity markets undervalue their prospects. Depressed share prices in 2023 meant issuing stock would be painfully dilutive.
By contrast, a revenue-based deal that investors price at (for example) a 15% IRR might be a less dilutive way to bridge to a milestone, even if that 15% is higher than the company's theoretical WACC. The key analytical question becomes: what is the opportunity cost of capital for the specific asset being financed?
For pre-commercial assets, traditional WACC calculations may understate true costs since they reflect the blended risk of the entire company rather than the standalone risk of an unproven drug. In such cases, revenue-based financing may actually represent a more appropriately risk-matched source of capital than either traditional debt (which requires fixed payments regardless of product success) or equity (which dilutes across all company assets, not just the one being financed).
In short, management must weigh the guaranteed obligation of sharing revenue (and its upper cap) against the uncertain upside of keeping 100% of future revenues by financing elsewhere. Rigorous scenario analysis is key: teams model low, base, and high sales projections, discount those cash flows, and compute IRRs to ensure the arrangement is palatable across outcomes.
Illustrative Cash Flow Waterfall
It's useful to visualize how cash flows split between a company and a revenue-based investor. Consider a hypothetical biotech that secures $30 million from an investor, agreeing to pay 10% of a therapy's quarterly net sales until the investor receives 1.5× ($45M). After that, the royalty rate drops to 2% for the deal's remaining life (a small ongoing "tail").
In early years when sales are modest, the 10% cut might barely cover accrued interest-equivalent—but as sales grow post-approval, the payments accelerate. For instance:

Company Revenue Distribution Over Time
Year 3-5 (Pre-Cap Phase):
├─ 10% to Investor ████
└─ 90% to Company ████████████████████████████████████
Year 6-7 (Post-Cap Transition):
├─ 2% to Investor █
└─ 98% to Company █████████████████████████████████████████████████
Year 8+ (Post-Obligation):
└─ 100% to Company ██████████████████████████████████████████████████This waterfall demonstrates several key analytical insights:
Front-Loading of Investor Returns: The investor's share is highest when the company's revenue is lower and their need for capital is greatest, and then diminishes once the investor achieves a sufficient return. This creates a natural alignment where the investor bears development risk but captures meaningful upside in early commercial years.
Asymmetric Payoff Structure: The company retains unlimited upside after the cap is reached, while the investor's returns are bounded. This is fundamentally different from equity, where dilution is permanent regardless of ultimate success.
Time Value Considerations: The investor's effective IRR is highly sensitive to the revenue ramp trajectory. Faster commercialization dramatically improves investor returns while reducing the company's total cost of capital—creating strong mutual incentives for execution excellence.
Such structures can be designed with more complex hurdles—for example, a two-tier IRR hurdle where the investor receives, say, 100% of a particular revenue stream until an 8% IRR is met, then 50% of that stream until a 15% IRR is achieved, after which the obligation ends.
This is analogous to private equity fund waterfalls, but in a biotech context ensures the investor gets a minimum preferred return before the company's coffers keep any surplus revenue. These tiered structures allow for sophisticated risk-sharing arrangements that can be calibrated to match the specific risk-return profiles of both parties.
Tiers, Caps and Downside Protection
Revenue-based financings are meticulously negotiated to balance upside and downside between the parties. Revenue Tiers and Return Caps are standard tools to calibrate this balance.
As seen in the Revolution Medicines deal, royalty rates often step down at higher sales levels, which prevents the investor from over-participating if the product becomes a runaway success. The logic: the investor is made whole (and then some) at moderate sales levels, after which the company should retain more profit from incremental sales.
From a financial theory perspective, this step-down structure resembles a call option spread: the investor has full participation up to a certain level, partial participation in a middle range, and minimal or no participation beyond an upper threshold. This limits the investor's convexity while preserving it for the company.
Deals frequently hard-cap the total return to the investor at a fixed multiple of the investment (often in the range of 1.5× to 4× the principal). Once that cap is hit, the royalty stops or reverts back to the company.
Caps protect the company's long-term upside—for example, if a digital therapeutic unexpectedly captures a huge market, it won't be forever sharing 10% of revenue; the obligation might end once the investor has, say, tripled their money.
Investors accept caps because their expected IRR can be achieved well before infinite upside—they price the deal to get, for instance, a 20% IRR if the product does merely "okay," and a windfall scenario isn't required for their thesis. Indeed, most investors would rather redeploy capital into the next deal after a certain point, rather than keep clipping coupons from an outsized winner indefinitely. This creates a natural recycling mechanism where capital flows from mature successes to new opportunities.
Downside Protection Mechanisms
On the flip side, downside protection provisions are built in to ensure investors aren't left high and dry if revenues disappoint. One common feature is a minimum return or "make-whole" mechanism: if the royalty payments are too low by a certain date, the company must compensate by making gross-up payments to reach an agreed return level.
In other words, if sales are slow or a milestone is missed, the deal morphs closer to a traditional loan—the company might owe fixed payments or a lump sum such that the investor realizes, say, at least an 8% IRR even in a downside case.
For instance, a biotech might agree that if cumulative royalties by 2028 are below a threshold, it will pay the difference in cash to ensure the investor has received the equivalent of 1.2× by that time (thereby partially guaranteeing the return). These "true-up" clauses protect the investor's floor, but they introduce more risk to the company (it must find cash independent of product revenue if the product flops).
The analytical implication is significant: what appears to be non-dilutive, revenue-contingent financing may actually carry hidden balance sheet obligations if downside scenarios materialize. Companies must model their liquidity under stress scenarios where both product revenues disappoint AND make-whole payments come due.
Some deals avoid explicit guarantees but include rate escalators: in the Revolution deal, if annual sales fall below an agreed floor in later years, the royalty rate on the lowest tier increases to compensate. This dynamic ratchet nudges the company to prioritize the product (or find other means to bolster payments) because a weak revenue year will make the next year's payments heavier.
Collateral and Security Interests
Another layer of protection is the use of liens and collateral. Many revenue-based fundings, especially development financings, secure the investor's interest with specific assets or IP. The investor might take a lien on the product's intellectual property or a priority claim on the royalty stream.
In practical terms, if the company defaults on promised payments, the investor can seize the drug's royalty rights or even force a sale of the asset to recover what's owed. This is akin to a mortgage on a house—non-payment can lead to foreclosure on the drug.
However, many such arrangements are non-recourse beyond the specified asset. Non-recourse means the investor's only remedy is against the product's revenues or IP, not the company's other assets. For example, a royalty monetization might be structured as a sale to a separate special-purpose vehicle: the investor's cash goes into the SPV which pays the company, and the SPV in turn is entitled to the product royalties; if the product fails, the investor cannot claim other corporate assets.
Non-recourse structures align with the high-risk nature of drug development—the investor knowingly bets on a molecule and may lose their investment if it fails clinically. This creates a more equity-like risk profile despite the debt-like payment structure.
In contrast, some hybrid deals (especially those more debt-like) do add recourse or corporate guarantees, blurring the line with traditional loans. These often come with covenants restricting additional debt or even further partnering of the product without consent.
Companies must tread carefully: while non-dilutive, revenue-based financings can encumber assets and limit future financing flexibility if not negotiated with an eye to the long term.
A biotech that pledges its crown-jewel drug for a synthetic royalty may find it harder to obtain bank debt or even to license that drug later, because the revenue stream is already spoken for (or any new lender would rank behind the royalty investor). The priority structure of claims becomes crucial in complex capital structures with multiple financing layers.
Thus, CFOs must map out scenarios: if a trial fails, how will the lien be handled? If a strategic acquirer comes along, can the royalty be bought out? Savvy companies often include buyout options or prepayment rights in the contract, giving them the ability to terminate the royalty by paying a negotiated amount (often the remaining cap plus a premium) should they want to clear the encumbrance—much like refinancing a loan.
Such flexibility can prove crucial if the landscape changes (for example, if equity markets improve, the company might refinance the revenue interest with a cheaper source of capital). The option value of these buyout provisions can be substantial and should be incorporated into the initial pricing and negotiation.
Recent Examples (2023–2025): Global Deals Across Sizes
What began as an exotic financing niche has become almost commonplace in biotech, with deals spanning from small startups to big pharma, across the U.S., Europe, and beyond. Below are several notable revenue-based financings from 2023 to 2025, illustrating the diversity of structures:
Sutro Biopharma & Blackstone (2023, USA)
Upfront $140M + up to $250M milestones – 4% revenue interest.
Sutro monetized a royalty it held on partner Vaxcyte's vaccine sales, securing immediate capital for its pipeline. Blackstone will receive 4% of Vaxcyte's future product sales; however, the deal is milestone-linked—Blackstone's additional $250M outlay is contingent on various return thresholds.
Analytical Insight: This structure effectively shares upside: if Vaxcyte's vaccine succeeds, Sutro gets more cash (up to $390M total) but gives up 4% of a high-selling product; if the vaccine flounders, Sutro at least keeps the upfront funds. The conditional milestone structure creates an interesting dynamic where Sutro's incremental capital access is correlated with the asset's derisking, but the company has already secured meaningful non-dilutive funding even if the product underperforms.
Notably, this was a non-dilutive raise for Sutro's own cancer drug development, demonstrating how even platform biotechs can leverage royalties on partnered programs to fund in-house assets. This represents a form of portfolio optimization where companies monetize lower-risk, partnered assets to fund higher-risk, wholly-owned programs.
Cara Therapeutics & HealthCare Royalty (2023, USA/Europe)
$40M for ex-U.S. royalties – capped 2.0× by 2029 (2.8× after).
Cara, a commercial-stage biotech, sold all its rights to royalties from its drug (Korsuva™ injection) in Europe and Japan to HCR, bolstering its cash runway. The deal included $17.5M now and $22.5M tied to near-term pricing and sales milestones.
HCR will collect the ex-U.S. royalties until it has received double its investment by 2029, or up to 2.8× if payments stretch beyond 2029. After that, the royalty stream reverts to Cara.
Analytical Insight: This cap and reversion illustrate a capped royalty monetization: the investor's return is substantial but finite, and the company preserves long-term upside (after the cap) as well as all U.S. revenues. For HCR, a specialized pharma investor, the appeal was a late-stage asset with existing approvals—relatively lower risk, hence the moderate 2× cap within 6 years (roughly equating to a low-teens IRR).
The geographic segmentation is particularly clever: Cara retains all U.S. revenue (typically the largest market) while monetizing ex-U.S. rights that might otherwise have generated smaller, later cash flows. This allows the company to optimize its capital structure by selectively monetizing the pieces of its asset portfolio with the best risk-adjusted pricing in the capital markets.
ImmunityBio & Oberland Capital (2024, USA)
$300M revenue interest + $20M equity – tiered royalties with a cap.
Facing the expensive task of commercializing a cancer immunotherapy, ImmunityBio raised up to $320M in a combined royalty + equity deal. Oberland provided $200M upfront and $100M more contingent on FDA approval (non-dilutive), and also invested $10M in equity (with an option for another $10M).
In return, Oberland gets a single-digit royalty on net sales of ImmunityBio's products, with tiered rates that are initially higher and then step down, and critically the payments are capped at a multiple of the investment.
While exact cap numbers weren't publicly disclosed in the press release, ImmunityBio's CEO emphasized the "cap on total payments" as a key benefit, limiting the cost of capital while avoiding equity dilution.
Analytical Insight: This deal also shows the flexibility of structures—blending a revenue interest with a small equity kicker (to sweeten upside) and even renegotiating terms with insiders (the company's founder aligned by extending and subordinating his loans to sit behind the new investor).
It's a complex but instructive case of late-stage biotech financing: rather than partner the drug with Big Pharma (which might bring in more money but at the price of handing over control and royalties), the company raised a largely non-dilutive war chest to go it alone on commercialization, with the revenue-based investor effectively betting alongside the company on the product's success.
The small equity component is analytically interesting: it provides the investor with uncapped upside participation (addressing the limitation of capped royalties) while keeping dilution minimal. This hybrid structure may become increasingly common as investors seek to optimize risk-adjusted returns across multiple instruments.
Revolution Medicines & Royalty Pharma (2025, USA)
Up to $2B total – $1.25B synthetic royalty + $750M loan.
In one of the largest deals of its kind, Revolution Medicines secured a massive funding package to develop and (if approved) market its RAS-inhibitor cancer therapy. The deal combined a synthetic royalty and a traditional loan: Royalty Pharma committed up to $1.25B for a royalty on future net sales of the therapy (with rates ranging ~0.5–2.5% on various sales tiers) and up to $750M in a six-year term loan.
Both components were contingent on milestones—e.g., $250M of the royalty was drawn immediately, but further tranches require positive Phase 3 data and FDA approval, and the term loan tranches depend on sales milestones.
Analytical Insight: The royalty portion is synthetic because Revolution has not out-licensed the drug; it's essentially selling a percent of its own future revenues. Royalty Pharma, known for purchasing existing drug royalties, here crafted a bespoke funding solution allowing Revolution to retain full control of development and commercialization while still accessing Big Pharma-scale capital.
The royalty has an interesting step-up clause: if annual sales are below a threshold by 2030, the royalty rate on the first $2B sales tier can increase in later years—a safeguard for Royalty Pharma to earn a suitable return even if the drug's uptake is slower than hoped.
This dynamic adjustment mechanism is analytically sophisticated: it effectively creates a floor on the investor's IRR by increasing the revenue share if commercialization lags, while still capping total participation if the product succeeds. The dual structure (royalty + loan) is also notable—it allows Revolution to access traditional debt markets (with fixed repayment obligations) while using the royalty structure for the riskier, success-contingent portion of the financing.
This deal underscores how revenue-based funding has evolved into a "new funding paradigm" for highly innovative biotech, as Royalty Pharma's CEO put it. It rivaled the size of a partnership deal, yet allowed the biotech to sidestep the typical trade-off of licensing (which often cedes commercial rights). The $2 billion scale demonstrates that revenue-based structures can now compete with traditional pharma partnerships for financing even the most capital-intensive development programs.
Sidekick Health & European Investment Bank (2025, EU/Iceland)
€35M venture debt for a digital therapeutics firm.
It's not just drug developers embracing alternative financing. Sidekick Health, a digital therapeutics and health platform operating in Europe and the U.S., signed a €35M venture debt facility with the EIB in April 2025.
While structured as a loan, this facility is a form of revenue-backed funding: it was provided under a program to support innovative life science companies and is likely repayable over time as Sidekick's revenues from digital therapy programs grow. The financing, backed by an EU guarantee, gives Sidekick capital to expand R&D and global reach without diluting founders or other investors.
Analytical Insight: Venture debt often carries warrants or covenants, but importantly it usually expects the company to have steady revenue or contracts that give lenders confidence in eventual repayment. Sidekick also raised a €7M equity injection alongside the loan, exemplifying a blended approach.
This highlights a trend in digital health globally: as venture capital became harder to obtain in 2023, companies turned to non-dilutive sources like loans, grants, and revenue-based instruments. In the U.S., specialized funds and platforms (e.g., firms like Lighter Capital or Novel Capital) have begun extending revenue-based financing to healthtech startups with predictable SaaS-like income.
These typically involve the startup paying a fixed percentage of monthly revenues until a set total is repaid. The Sidekick deal shows that even in Europe—historically more reliant on grants—new models are emerging, supported by public investment banks to catalyze the digital therapeutics sector. The involvement of a public institution like the EIB also suggests that policymakers recognize the strategic value of non-dilutive financing in supporting innovation while preserving entrepreneurial ownership and control.
Conclusion
In an era of expensive equity and scarce traditional funding, revenue-based financing has moved from the fringes to the mainstream of biotech and digital health finance. These deals are complex, bespoke agreements, often blending features of royalties, loans, and venture capital all at once.
They require financial sophistication to negotiate—mapping out revenue scenarios, IRR hurdles, and legal covenants is as vital as the science itself. But when structured well, they offer a compelling value proposition: companies secure crucial cash to advance therapies (while keeping control and avoiding brutal dilution), and investors earn attractive, steady returns linked to real economic output rather than paper valuations.
It's a model rooted in the old idea of sharing revenue with backers, now updated with modern financial engineering to include tiered royalties, milestone gating, and downside safeguards.
Globally, we can expect these financing paradigms to continue growing. Industry surveys show an annual growth rate of over 30% in synthetic royalty financings in recent years, and roughly $14 billion per year in royalty/revenue monetization deal flow.
As more funds—from specialist pharma investors in New York to sovereign wealth funds in the Middle East—hunt for yield uncorrelated with public markets, the appetite to invest in drugs' future revenues will remain strong. The asset class offers attractive characteristics: relatively predictable cash flows once products are approved, downside protection through structured terms, and returns that are insulated from general equity market volatility.
For companies, the calculus will evolve with the market: when biotech stocks rebound or interest rates shift, the relative cost of revenue-based capital will be remeasured. Yet, the strategic advantages of these deals (flexibility and non-dilution for the issuer, customized risk/return for the investor) mean they are here to stay as a financing tool.
The analytical framework for evaluating these structures is becoming more sophisticated, with both companies and investors developing better models for pricing uncertainty, structuring protections, and optimizing the trade-offs between flexibility and cost.
One might say that revenue-based funding deals let biotech firms "have their cake and eat it"—they get to bake a larger pie (by funding growth) without giving away the bakery. Of course, a slice of future revenues is promised to the financiers, but unlike equity, those financiers won't stay around for the entire feast—once they've eaten their fill (hitting their return cap), the rest of the pie reverts to the company and its shareholders.
For today's biotech CFOs, the task at hand is to slice the pie just right: offer a compelling portion to attract capital, while preserving enough future value to make the gamble worthwhile. It's a delicate balance of science and finance—one that will continue to evolve as the industry writes the next chapter in funding innovation.
