Protect Your Sale: CA Stock Purchase Agreements Explained

What Is a Stock Purchase Agreement (SPA)?

A stock purchase agreement is a contract for buying or selling shares of a corporation. Unlike an asset purchase, a stock purchase transfers ownership through shares, typically leaving the corporation’s contracts, employees, permits, and liabilities in place. In California, SPAs are governed by contract and corporate law and often incorporate securities-law steps when the deal involves an offer or sale of securities. See the California Corporations Code and DFPI’s overview of securities regulation.

Why California Law Matters

California’s Blue Sky laws regulate offers and sales of securities in the state and generally require qualification unless an exemption applies (Corp. Code § 25110; § 25102 (exemptions)). Corporate governance is usually governed by the state of incorporation (the internal affairs doctrine), but limited California overlays may apply to certain foreign corporations with substantial California ties (§ 2115). California also provides shareholder rights (e.g., inspection rights: § 1601) and prescribes mechanics for board and shareholder actions that can affect deal timing.

Key Deal Terms to Protect Your Sale

• Parties and capitalization: Identify sellers, buyers, classes of stock, options, warrants, SAFEs/convertibles. Attach a cap table and option ledger.
• Purchase price and adjustments: Define price, escrow/holdback, and any working capital, indebtedness, or cash adjustments measured at closing.
• Representations and warranties: Company reps (organization, capitalization, financials, contracts, IP, employees, taxes, compliance); seller authority and title; buyer authority and, if applicable, financing. Use materiality qualifiers and disclosure schedules.
• Covenants: Pre-closing operations, access to information, efforts to obtain consents, interim restrictions on dividends or issuances, and any non-solicitation or other restrictions as permitted by California law (see Bus. & Prof. Code § 16600).
• Conditions to closing: Required approvals, accuracy of reps at closing, no material adverse change, delivery of ancillary documents, third-party consents, and compliance with applicable California corporate and securities requirements.
• Indemnification: Survival periods, baskets, caps (overall and for fundamental reps like organization, capitalization, authority, and title), escrows/holdbacks, special indemnities, and claim procedures. Define fraud, knowledge, and any materiality scrape carefully.
• Post-closing matters: Transition services, employee matters, option/RSU treatment, IP assignments, and restrictive covenants consistent with California law.
• Dispute resolution: Specify governing law and venue; consider arbitration vs. courts; fee-shifting clauses.

California Corporate Approvals and Shareholder Consents

Whether corporate action is required for a stock sale depends on the transaction structure and the governing documents. Many private corporations impose transfer restrictions (e.g., rights of first refusal or consent rights) in their articles, bylaws, or investor agreements; these may require company or investor approvals before shares can be transferred (Corp. Code § 204(a)(2)). If the company itself is a party to the SPA, board action is commonly needed, and shareholder action may be required by the governing documents or agreements. California prescribes mechanics for shareholder meetings and written consents (§ 603). Confirm that all required approvals and notices are properly obtained and documented.

Securities Law Compliance in California

Stock is a security. In California, offers or sales generally must be qualified unless an exemption applies (§ 25110). Private deals commonly rely on exemptions that depend on investor type/number, offering method, and whether commissions are paid (§ 25102). In some cases, California notice filings or fees are required to perfect an exemption; DFPI provides guidance and forms (DFPI Securities). Federal securities laws may also apply, so parties typically confirm compliance with both regimes.

Employee Equity and Option Exercises

Address how outstanding options and other awards will be handled at closing (exercise, cash-out, assumption, or cancellation). California provides a compensatory plan exemption with conditions (§ 25102(o)). Ensure any exercises, cancellations, or issuances comply with the plan, grant agreements, and available exemptions.

IP, Data, and Regulated Assets

Because a stock sale preserves the corporate entity, licenses, data, and regulatory approvals generally remain with the company. However, many contracts include change-of-control or assignment-by-law provisions that can treat a stock sale as a transfer requiring consent. The SPA should identify these contracts and make obtaining any required consents a closing condition. For regulated businesses (e.g., healthcare, cannabis, finance, insurance), additional California agency approvals may be needed.

Indemnification and Risk Allocation

Indemnification allocates risk for breaches of representations, covenants, and specified liabilities. Common tools include survival periods (by claim type), baskets (deductible or first-dollar), caps (overall and for fundamental reps), special escrows/holdbacks, and set-off rights. Define fraud, knowledge, and materiality scrapes carefully. Be mindful that restrictive covenants (e.g., non-competes) are generally void in California except in limited statutory contexts (Bus. & Prof. Code § 16600).

Common Pitfalls

• Overlooking investor contractual rights (e.g., ROFRs, co-sale, consent rights)
• Assuming an exemption applies without confirming California notice/filing or fee requirements
• Missing change-of-control consents in key customer or vendor contracts
• Unreconciled cap table discrepancies before signing
• Inadequate tax planning for sellers and the corporation
• Overreliance on broad as-is language instead of tailored reps and schedules

FAQs

Do I need California approval to sell existing shares privately?

Not usually, but an exemption from qualification must apply and related notices or fees may be required under California law.

Does a stock sale trigger assignment clauses?

Often yes. Many contracts treat a change of control as an assignment, requiring consent before closing.

Can I include a non-compete in an SPA under California law?

Generally no, except for narrow statutory exceptions. Consider confidentiality, non-solicit, and trade secret protections instead.

Which state’s law should govern my SPA?

Many parties choose Delaware or California. Consider incorporation state, nexus, enforcement, and investor expectations.
