Joint Brokerage Success Fees: Helping Secure Funding Does Not Require “But For” Causation

Case: Alphier Capital Two Llp v Blyvoor Gold Capital (Pty) Ltd [2026] EWCA Civ 1432

Court: England and Wales Court of Appeal (Civil Division)
Date: 9 November 2026
Judges: Miles LJ, Foxton LJ and Butcher LJ

1. Introduction

This decision concerns the causal connection required between a financial broker’s services and a completed financing before a contractual success fee becomes payable. Its particular significance lies in the transition from separate brokerage appointments to an expressly collaborative arrangement involving two brokers and an already identified investor.

Blyvoor Gold Capital (Pty) Ltd, a South African mining company, challenged an award of US$2.25 million to the respondent, described throughout the judgment as “Exotix”. Although another broker, Legacy Hill, introduced the eventual investor and led the negotiations, Exotix supplied financial modelling, analysis and advice that helped Blyvoor evaluate and accept the proposed financing.

The Court of Appeal unanimously dismissed the appeal. On the proper construction of the parties’ agreements, Exotix’s obligation to “help place” the investment required its individual services to have a “real world effect” on obtaining the financing. That effect could consist of helping Blyvoor become willing to accept the investor’s proposal. Exotix did not have to demonstrate that it changed the investor’s behaviour or that the transaction would have failed without its involvement.

The ruling is a contextual interpretation of particular contractual language, not a universal relaxation of the requirements governing brokerage commission.

2. Background and Contractual Structure

The financing project

Blyvoor acquired a disused South African gold mine in 2016 and sought funding to restore production. The Industrial Development Corporation of South Africa (“IDC”) was prepared to provide only part of the required finance. Blyvoor therefore engaged brokers to secure private investment.

Exotix was a regulated investment bank with substantial technical and back-office resources. Legacy Hill was essentially a two-person operation. Both were appointed non-exclusively, but Legacy Hill introduced Orion Resource Partners (UK) LLP (“Orion”), a major mining investor, which quickly became the principal funding prospect.

The original Exotix engagement

The engagement letter dated 1 March 2018 appointed Exotix as structuring agent, financial adviser and placement agent. Its services included project coordination, structural and valuation advice, preparation of offering materials and helping place investments with investors introduced by Exotix.

The original success fee was 5% of the relevant investments, payable at “Completion”. That definition was tied to investment by an “Exotix Investor”—an investor introduced by Exotix. By the end of the trial, the parties agreed that the original arrangement required Exotix to be an effective cause of the financing.

Because Legacy Hill had introduced Orion, Exotix could not earn commission on Orion’s investment under the engagement letter as originally drafted.

The Tripartite Agreement

Blyvoor nevertheless wanted access to Exotix’s analytical capabilities and other resources. In late March or early April 2018, Blyvoor, Exotix and Legacy Hill entered into a Tripartite Agreement to pursue approximately US$70 million, or part of that amount, from Orion jointly.

The agreement preserved the existing engagement terms unless modified, but replaced the relevant Exotix success-fee provision for Orion funding. The agreed fees were:

Broker Initial fee Subsequent fee Total
Exotix 3% 0.75% 3.75%
Legacy Hill 2% 0.5% 2.5%
Combined 5% 1.25% 6.25%

Exotix’s initial fee became payable upon receipt of Orion funding, with the subsequent fee payable on the eighteenth anniversary month of the initial payment. More precisely, the contractual wording specified the 18-month anniversary. The agreement covered the aggregate principal amount of both equity and debt funding from Orion.

This arrangement changed the commercial premise of remuneration: the parties now expressly contemplated that both brokers could receive commission on the same financing, notwithstanding that only Legacy Hill had introduced Orion.

Performance and dispute

Exotix analysed Orion’s financing proposals, advised on gold-offtake pricing, reviewed the term sheet and arranged financial modelling. Legacy Hill remained the principal intermediary and maintained the closer relationship with Orion.

The transaction proved easier to complete than anticipated. A term sheet was signed in April 2018 and final funding agreements in August 2018. Exotix learned of completion in January 2019. Proceedings concerning its fee began in March 2023.

3. The High Court Decision and the Issues on Appeal

Richards J held that the surviving obligation to “help place the Investments”, read in light of the Tripartite Agreement, required Exotix’s own actions to have a real-world effect on securing Orion funding. He found that its services satisfied that requirement and awarded US$2.25 million.

Two boundaries to the appeal are important:

  • No revived implied-term argument: Blyvoor did not appeal the rejection of its alternative argument that an effective-cause requirement should be implied.
  • No renewed claim to effect-free remuneration: Exotix did not challenge the rejection of its contention that performing services, without showing any particular effect, was sufficient.

The appeal therefore concerned the interpretation and application of the express agreements. Blyvoor advanced three grounds:

  1. The judge adopted an insufficiently demanding causal test, particularly by accepting work that influenced Blyvoor rather than Orion.
  2. The judge applied his own test inconsistently and wrongly reasoned that an uncomplicated transaction required only a limited contribution.
  3. The conclusion that Exotix’s work satisfied the test was unsustainable, especially given the size of its fee and Legacy Hill’s greater role.

Foxton LJ rejected all three grounds. Butcher LJ and Miles LJ agreed.

4. Legal Reasoning

A. The revised agreement changed the causal inquiry

The original effective-cause requirement arose principally from provisions linking commission to an investor introduced by Exotix. Those provisions could not operate unchanged in an agreement exclusively concerned with Orion, an investor already introduced by Legacy Hill.

The court identified two fundamental changes:

  • Exotix could no longer perform the introductory function that ordinarily established the relevant causal connection.
  • The usual concern about competing agents claiming commission was displaced by an express arrangement for joint work and payment to both brokers.

Consequently, recognising an effective-cause requirement under the original engagement did not require an equivalent obligation under the Tripartite Agreement. Any continuing effective-cause requirement was necessarily attenuated by the revised structure.

B. “Help place” required an actual contribution, not indispensability

The court upheld the requirement that Exotix’s individual services have a real-world effect on obtaining finance. Merely performing contractual tasks while a successful transaction happened independently would not suffice.

However, “help place” did not require Exotix to establish that:

  • the transaction would not have occurred without its services;
  • its work changed Orion’s financing terms;
  • it persuaded Orion to invest; or
  • its contribution exceeded Legacy Hill’s contribution.

A strict “but for” test would have fitted poorly with the joint appointment. If both brokers had to prove that their respective contributions were indispensable, they would have incentives to duplicate work or compete for tasks rather than cooperate.

The court did not replace causation with participation. Its distinction was between services that actually assisted completion and services whose performance had no demonstrated effect.

C. Assistance to the borrower could help secure the investment

Blyvoor argued that qualifying work had to influence Orion’s willingness to provide funding, rather than Blyvoor’s willingness to accept it. The court rejected that distinction.

A financing agreement requires acceptance on both sides. Helping the borrower understand pricing, compare alternatives and become comfortable with an offer can contribute to the transaction just as genuinely as persuading the investor to alter its proposal.

This conclusion followed both the ordinary meaning of “help place” and the known reason for Exotix’s appointment. Blyvoor expected to need financial modelling to compare Orion’s proposed options, and regarded Exotix as having expertise that Legacy Hill lacked.

It would therefore have been artificial to reward analysis that prompted an accepted counter-offer while excluding analysis showing that the existing offer was acceptable. Neither the contractual wording nor the commercial context supported that distinction.

D. Advice and placement assistance were not mutually exclusive

The original engagement listed advisory services separately from helping place investments. Blyvoor argued that the judge had rejected advice alone as sufficient, only to award a fee for advice.

The court explained that the provisions were not “watertight compartments”. Advice could also constitute placement assistance if it actually helped bring about agreement. The judge had rejected entitlement based on the mere provision of advice, not the possibility that effective advice could satisfy the placement obligation.

This distinction reconciled the judge’s reasoning: Exotix’s work qualified because of what it contributed to the particular transaction, not simply because it fell within a listed service category.

E. The size of the fee did not determine the required volume of work

Blyvoor emphasised that Exotix’s agreed remuneration was 50% greater than Legacy Hill’s. The court accepted that this reflected the potential value of Exotix’s capabilities. It did not follow that Exotix’s entitlement depended on those capabilities being required to the anticipated extent.

The parties had purchased access to expertise against uncertain future demands. The fact that the financing proved relatively straightforward did not retrospectively introduce a requirement that Exotix perform work commensurate with the fee.

That conclusion reflected the economics of success fees. Brokers may undertake substantial unpaid work on unsuccessful projects, while receiving fees exceeding the objective value of their work when a transaction succeeds. Such asymmetry is part of the contingent bargain, not itself evidence of commercial absurdity.

F. The evidence supported the judge’s evaluation

Three areas of work supported the finding of a real-world effect:

  1. Gold-offtake pricing: Exotix helped Blyvoor understand a proposal allowing gold purchases by reference to the lowest market price within an eight-day quotation period, compared with an alternative market-price discount.
  2. Term-sheet review: Exotix supplied written comments reflected in the marked-up term sheet returned to Orion.
  3. Financial modelling: Its modelling evaluated Orion’s offer against future gold-price expectations and alternative quotation periods.

These activities addressed specific proposals and contributed to the process by which the parties agreed a deal. Conversely, the judge did not treat Exotix’s IDC interactions as qualifying assistance: they had not materially influenced IDC’s decision or helped secure Orion funding. This demonstrated that the test involved discriminating evaluation rather than automatic credit for every service performed.

5. Precedents Cited and Their Influence

Arnold v Britton [2015] AC 1619

This supplied the agreed framework for contractual interpretation. Both parties accepted that the necessary principles appeared in Lord Neuberger’s judgment at paragraphs 14–22, and the Court of Appeal adopted the same approach as Richards J.

The agreement’s language had to be read in its contractual and commercial setting. Commercial considerations helped explain the joint appointment, but did not justify adding a requirement that Exotix’s fee correspond to the amount of work ultimately needed. The court interpreted the bargain rather than revising it in hindsight.

Doyle v Mount Kidston Mining and Exploration Pty Ltd [1984] 2 Qd R 386

The court considered McPherson J’s observation that merely finding someone who later purchases independently of further agency involvement does not necessarily establish entitlement to commission.

The authority helped explain why “introduction” can carry a causal requirement. Its importance here was contextual: the original Exotix arrangement linked remuneration to introducing the investor, while the Tripartite Agreement deliberately addressed an investor introduced by someone else.

Rasmussen & Russo Pty Ltd v Gaviglio (1982) Qd Rep 571

In this case, an introduced purchaser could not obtain finance and withdrew. The first agent’s instructions ended. A second agent subsequently arranged finance and completed the transaction.

The first introduction did not earn commission because the later transaction followed a substantial interruption and another agent’s effective intervention. The case illustrates a “spent” introduction: historical contact alone does not necessarily remain causally operative.

The Court of Appeal used it to explain the limits of introduction-based entitlement, not as a direct factual analogy to the expressly cooperative arrangement before it.

LJ Hooker Ltd v W J Adams Estates Pty Ltd (1977) 138 CLR 52

Barwick CJ’s reasoning, discussed through the other agency authorities, explained that an agent who introduces someone who becomes the purchaser ordinarily acts as an effective cause. That conclusion is not necessarily defeated because the purchaser might have bought anyway or because the principal’s own efforts also contributed.

This supported the distinction between effective causation and exclusive or indispensable causation. The agency authorities did not support treating every commission claim as requiring proof that the transaction would otherwise have failed.

Nahum v Royal Holloway and Bedford New College [1999] EMLR 252

Waller LJ explained that, absent contractual language requiring another interpretation, introducing a buyer carries an effective causal element: the agent’s actions must really bring about the buyer–seller relationship.

The case also questioned whether much ordinarily turns on describing the agent as “an” rather than “the” effective cause, while recognising possible significance where competing agents claim introductory commission.

It helped establish the introduction-based background against which the Tripartite Agreement operated. The agreement’s express provision for collaborative work and payment to both brokers materially changed that background.

MSM Consulting Ltd v United Republic of Tanzania [2009] EWHC 121 (QB)

The court cited this decision for the proposition that a principal reason for implying an effective-cause requirement is to minimise the risk of a client paying two commissions.

That concern had limited relevance here because the parties expressly agreed to pay both brokers. The citation explained the commercial function of conventional effective-cause requirements; it did not revive the implied-term issue abandoned on appeal.

Henderson v Foxworth Investments Ltd [2014] UKSC 41

This authority governed the challenge to the trial judge’s evaluative conclusion. Blyvoor had to show that the conclusion could not reasonably be explained or justified, rather than merely persuade the appellate court that another evaluation was possible.

Richards J had identified particular services and explained their contribution to agreement. Those reasons provided a sufficient foundation for his conclusion, so the appellate challenge failed.

The accompanying agency commentary

The court also referred to Bowstead & Reynolds on Agency, 23rd edition. The quoted discussion explained that an agent who causes a person to negotiate and contract, without a substantial break, will ordinarily earn commission without necessarily conducting negotiations or persuading either party to contract. This reinforced the rejection of an unnecessarily demanding conception of effective cause.

6. Complex Concepts Simplified

Effective cause
A legally sufficient connection between an agent’s work and the completed transaction. Its precise content depends on the contract; it does not invariably mean the sole or indispensable cause.
“But for” causation
The question whether the transaction would have happened without the broker’s work. The court declined to impose that requirement on each participant in this joint brokerage arrangement.
Real-world effect
An actual contribution to obtaining the financing. Transaction-specific analysis that helps the borrower accept an offer can qualify; activity without demonstrated effect does not.
Factual matrix
The commercial circumstances surrounding the agreement, including the brokers’ different capabilities, Orion’s existing involvement and the intended division of work.
Express interpretation and implied terms
Interpreting express terms determines what the parties’ words mean. Implying a term adds an obligation not expressly stated. Only the former issue remained live on appeal.
Evaluative conclusion
A judgment applying a legal standard to the evidence as a whole. An appeal does not succeed simply because another judge might have assessed the contribution differently.

7. Impact and Limits

Collaborative financial mandates

The decision is particularly relevant where an introducer and a technical adviser work together under a revised fee arrangement. Analytical or borrower-facing work can satisfy an obligation to help secure financing even where another intermediary leads investor communications.

Drafting consequences

Parties should specify whether remuneration depends on introduction, completion, material contribution, investor-facing activity or identified deliverables. A revised mandate should also state clearly which original conditions survive. If payment is intended to depend on a minimum level of work or particular results, that requirement should be expressed rather than inferred from the fee’s size.

Evidence of contribution

Advisers relying on assistance rather than introduction should retain evidence connecting their work to the transaction: analyses of actual offers, incorporated drafting comments and records showing how advice assisted decision-making. The relevant question is contribution, not simply hours recorded.

No automatic entitlement

The ruling does not establish that every useful service earns a success fee, or that effective-cause requirements disappear whenever several advisers participate. Express wording remains decisive. Nor did the court determine whether Exotix could recover without any causal contribution: that broader position was not pursued on appeal.

Its central significance is narrower: a requirement to “help place” investment, within this expressly joint arrangement, was satisfied by actual assistance to completion without proof of indispensability or investor persuasion.

8. Conclusion

The Court of Appeal upheld the US$2.25 million award because Exotix’s transaction-specific analysis and advice genuinely helped Blyvoor reach agreement with Orion. Legacy Hill’s leading role, the relative ease of completion and the size of Exotix’s fee did not negate that contribution.

The key lesson is that commission conditions must be interpreted within the commercial structure actually agreed. Where brokers are appointed to cooperate and both may be paid, “helping” secure financing need not mean introducing the investor, changing its position or proving that the deal depended on one broker alone.
