South San Francisco Earnout Agreements Lawyer
The ink dries on a letter of intent, hands are shaken, and then comes the part of an acquisition that most founders and sellers underestimate: the earnout. Within the first 24 to 48 hours after an earnout structure is proposed, buyers and sellers are often already talking past each other. The buyer’s team frames it as a reasonable way to bridge a valuation gap. The seller hears it as a bet that they will earn what was already promised. That tension, present from the very first draft, is exactly why having a skilled South San Francisco earnout agreements lawyer involved early in the process is not optional. It is the difference between an earnout that works as intended and one that becomes a dispute two years after closing.
What Earnouts Actually Do and Why They Go Wrong
An earnout is a contractual mechanism used in mergers and acquisitions that ties a portion of the purchase price to the future performance of the acquired business. In theory, it aligns incentives between buyer and seller. In practice, it creates one of the most contested areas of post-closing M&A litigation. Courts across the country, including those in California, regularly see disputes over whether a buyer deliberately managed an acquired company in ways that made hitting earnout milestones impossible. These cases are complex, expensive, and often avoidable with better drafting upfront.
The most common sources of earnout failure are not financial. They are definitional. Terms like “revenue,” “EBITDA,” “gross profit,” and “net sales” sound straightforward, but each can be interpreted dozens of ways when a buyer is controlling the post-closing books. Does revenue include deferred payments? Are intercompany allocations counted against EBITDA? What accounting standards apply, and who has the right to change them? Triumph Law advises clients to treat every financial metric in an earnout as a potential argument waiting to happen, and to draft the agreement accordingly.
The structure of earnout periods matters just as much as the metrics themselves. Short earnout periods of one to two years often leave sellers feeling squeezed. Longer periods of three to five years introduce more uncertainty about how the buyer will operate the business. In either case, sellers need clear operational covenants that require the buyer to run the acquired business in a way that gives the earnout a genuine opportunity to be achieved. Without those protections, an earnout can become a way for a buyer to acquire a company at a discount.
Recent Trends Shaping Earnout Disputes in Technology and Life Sciences
South San Francisco sits at the heart of one of the most deal-active biotech corridors in the world. The area, sometimes called “Biotech Bay,” is home to dozens of life sciences companies at various stages of development. In this environment, earnouts tied to regulatory milestones, clinical trial outcomes, or product approval timelines are common. These milestone-based earnouts carry a distinct set of legal risks compared to financial performance earnouts, and litigation trends over the past several years have revealed just how sharply those risks can cut.
Delaware courts, which govern a substantial portion of major M&A transactions regardless of where the parties are located, have increasingly scrutinized whether buyers comply with obligations to use “commercially reasonable efforts” or “best efforts” to achieve earnout milestones. In a series of decisions, Delaware’s Court of Chancery has found buyers liable for failing to pursue regulatory approvals or commercial strategies that would have triggered earnout payments. These rulings have created pressure on both sides to define effort standards with far greater specificity than was common even five years ago. California courts have developed their own line of analysis under implied covenant of good faith principles, adding another layer of consideration for deals involving California-based companies.
The technology sector around South San Francisco and the broader Peninsula has seen a parallel rise in earnout disputes tied to software performance benchmarks, user growth metrics, and recurring revenue targets. As SaaS and platform companies have become acquisition targets at premium valuations, buyers have used earnouts to manage downside risk. Sellers in these transactions need to think carefully about what the buyer controls post-closing that could affect those metrics, including pricing decisions, marketing spend, sales team integration, and product roadmaps. A well-drafted earnout agreement addresses all of these variables explicitly.
Structuring Earnout Agreements That Hold Up
At Triumph Law, the approach to earnout agreements starts with understanding the deal, not just the document. Before drafting a single definition, experienced counsel needs to understand how the acquired business generates revenue, what operational decisions most directly affect performance, who will be managing the business after closing, and what the seller’s realistic role will be during the earnout period. These facts shape every substantive provision in the agreement.
The most protective earnout agreements include several elements that less experienced counsel often overlook. First, they define financial metrics by reference to a specific accounting methodology that cannot be changed unilaterally by the buyer. Second, they include operational covenants that constrain the buyer from taking actions that would artificially suppress performance, such as redirecting customers to other product lines, cutting sales resources, or eliminating key personnel. Third, they establish clear dispute resolution mechanisms, including access to books and records, independent accountant review rights, and deadlines that prevent a buyer from stalling.
Sellers should also consider whether an earnout is the right structure at all. In some transactions, a better outcome can be achieved through an adjusted purchase price, escrow arrangements, or representations and warranties insurance rather than tying value to post-closing performance. Part of the value that a transactional attorney brings to these discussions is helping clients evaluate the full range of deal structures and understand the risk profile of each. Triumph Law’s attorneys bring that kind of transactional judgment to every deal, regardless of which side of the table they are representing.
Representing Both Buyers and Sellers in Earnout Transactions
One of the factors that distinguishes Triumph Law’s counsel on earnout matters is the firm’s experience representing both acquirers and targets. Having negotiated from both sides, the attorneys at Triumph Law understand what buyers are trying to protect when they propose an earnout and what leverage sellers have in pushing back. That dual perspective informs the strategy in any given transaction, allowing clients to understand not just what a provision means, but why the other side wants it and what they are likely willing to concede.
For buyers, earnout agreements must be structured to avoid creating implied obligations that could expose them to liability for operating decisions they make in good faith after closing. Buyers need flexibility to integrate the acquired business, respond to market conditions, and make strategic pivots without triggering breach of contract claims. Achieving that flexibility while still offering an earnout that a seller will accept requires careful drafting and a clear understanding of the post-closing operating plan.
For sellers, the primary concern is ensuring that the earnout is achievable under realistic assumptions and that the buyer cannot engineer a miss. This means reviewing not just the earnout provisions themselves, but the broader acquisition agreement for provisions that could affect performance, including non-compete clauses, transition services agreements, and representations about the buyer’s post-closing intentions. Triumph Law reviews all of these documents as part of a comprehensive approach to earnout representation.
South San Francisco Earnout Agreements FAQs
How common are earnouts in South San Francisco M&A transactions?
Earnouts are especially common in the life sciences, biotech, and technology sectors that define the South San Francisco business community. In deals where there is a gap between a buyer’s valuation and a seller’s expectations, or where the acquired company’s future performance is uncertain, earnouts provide a way to bridge that gap. Industry data consistently shows that earnouts appear in a significant share of life sciences acquisitions nationally, and the concentration of biotech companies in this region makes earnout literacy particularly important for local founders and investors.
What is the most common reason earnout payments are disputed after closing?
The most frequent source of dispute is disagreement over how financial metrics are calculated. When an earnout is tied to revenue or EBITDA, buyers and sellers often have different assumptions about what costs or revenue streams are included. Disputes also arise when sellers believe the buyer managed the business in ways designed to suppress earnout performance. Clearly defined metrics and operational covenants are the primary tools for preventing these disputes before they arise.
Can a seller negotiate protections against a buyer undermining earnout performance?
Yes, and doing so is one of the most important aspects of earnout negotiation. Sellers can negotiate covenants requiring the buyer to maintain adequate resources for the acquired business, prohibiting diversion of customers or revenue to other entities, and requiring the buyer to operate the business in a manner consistent with past practice or an agreed business plan. The strength of these protections depends significantly on how they are drafted and what remedies are available if they are violated.
What happens if the buyer and seller disagree about whether an earnout milestone was met?
Most earnout agreements include a dispute resolution process, typically involving an independent accountant or expert who reviews the calculations and renders a binding decision. If the agreement does not include a clear dispute resolution mechanism, the parties may end up in litigation. California courts and Delaware courts both have developed substantial case law governing earnout disputes, and outcomes depend heavily on the specific language of the agreement and the conduct of the parties after closing.
Does Triumph Law represent clients outside of Washington D.C. in earnout matters?
Yes. While Triumph Law is headquartered in Washington D.C., the firm’s transactional practice regularly supports deals involving companies throughout the country, including technology and life sciences companies in California. Earnout structuring and negotiation is a document-intensive, judgment-driven practice that does not depend on physical proximity to the client’s location.
How early in a transaction should an earnout lawyer be involved?
As early as the term sheet stage. Many of the most important earnout terms, including the performance metric, the measurement period, and the effort standard, are first established in the term sheet or letter of intent. If those terms are poorly defined at the outset, it becomes significantly harder to correct them during full agreement negotiations. Involving counsel before signing a term sheet gives clients the best opportunity to shape the structure from the beginning.
