The story

Acacia was incorporated in California in January 1993 by Bruce Stewart and reincorporated in Delaware in December 1999. Stewart founded the business with the intention of using investment capital for innovation. In 2000, under the leadership of Paul Ryan and Chip Harris, it moved to concentrate on technology backed by strong patents. Acacia’s operations have since expanded into three verticals: Intellectual Property Operations, which includes patent licensing, enforcement and technologies business; Energy Operations; and Industrial Operations.

As of June 30, 2025, Acacia’s book value was $577.5 million and there were 96.4 million shares of common stock outstanding, for a book value per share of $5.99. In the second quarter of 2025, the company’s total revenues were $51.2 million, up 98% compared to $25.8 million in the same quarter of 2024. This was composed of $0.3 million generated by the company’s Intellectual Property business, $6.6 million by Printronix, $15.3 million by Benchmark Energy and $29.0 million by Deflecto.

The company’s principal executive office is in New York City.

On August 6, 2025 Acacia partnered with Unchained and Build Asset Management to purchase whole loans collateralized by Bitcoin.

Risk factors and legal proceedings

The risks Acacia Research names in Item 1A of its 10-K filed Mar 12, 2026: 66 risks under these headings, as written.17

  • Risks Related to Our Business and Business Strategy
  • We intend to grow our company by acquiring additional operating businesses, energy assets and intellectual property assets, which may not occur, and any acquisitions that we complete will be costly and could negatively affect our results of operations, and dilute our stockholders’ ownership, or cause us to incur significant expense, and we may not realize the expected benefits of our operating businesses because of difficulties related to integration.
  • Our success is dependent on our ability to attract and retain the employees and management teams of our operating businesses, the loss of whom could materially adversely affect our financial condition, business and results of operations.
  • The success of our Company and the integration of our operating businesses is dependent on our relationship with Starboard.
  • The due diligence process we undertake in connection with new acquisitions of operating businesses or intellectual property assets may not reveal all material facts.
  • Our acquisition strategy may include acquisitions of privately held companies, which provide more limited information, may be dependent on the talents and efforts of only a few key portfolio company personnel, and have greater vulnerability to economic downturns when compared to public company targets.
  • If, in the future, we cease to control and operate our operating businesses, we may be deemed to be an investment company under the Investment Company Act of 1940, as amended.
  • Both we and our operating businesses outsource a number of services to third-party service providers, which are subject to risk of disruptions, delays, and decrease in our control, which could adversely impact our operational results.
  • We may be limited in our ability to use our net operating losses and certain other tax attributes.
  • We identified a material weakness in our internal control over financial reporting at Benchmark.
  • Data security and integrity are critically important to our business, and cybersecurity incidents—including cyberattacks, breaches of security, unauthorized access to or disclosure of confidential information, business disruption, or the perception that confidential information is not secure—could result in a material loss of business, regulatory enforcement, substantial legal liability and/or significant harm to our reputation, which could have a material adverse effect on our business, financial condition and results of operations.
  • We have a history of losses, and we may not be consistently profitable in the future.
The other 55 risks
  • Public health threats, pandemics and outbreaks of communicable diseases could have a material adverse effect on our operations, the operations of our business partners, and the global economy as a whole.
  • We are a “controlled company” within the meaning of the Nasdaq listing standards and, as a result, qualify for, and may in the future decide to rely on, exemptions from certain corporate governance requirements. As a result, our stockholders will not have the same protections afforded to stockholders of companies that are subject to such requirements if in the future we determine to take advantage of any of the controlled company exemptions.
  • Our principal stockholder, Starboard, controls 63.4% of the voting power of our Common Stock, and its interests may conflict with our other stockholders in the future.
  • Changes in U.S. foreign trade policies, including the imposition of additional tariffs and other trade barriers, and efforts to withdraw from or materially modify international trade agreements, may materially and adversely affect our business, operations and financial condition.
  • Disruptions in the worldwide economy may adversely affect our business, results of operations, and financial condition.
  • For more information, refer to “—Risks Related to our Manufacturing Operations Business—Our Manufacturing Operations Business’s operating results can be adversely affected by inflation, changes in the cost or availability of raw materials, labor, energy, transportation and other necessary supplies and services, as well as the impact of tariffs and changes in a country’s or region’s political or economic conditions.”
  • Risks Related to our Intellectual Property Business and Industry
  • Our Intellectual Property Business is reliant on the strength of our patent portfolios and is subject to evolving legislation, regulations, and rules associated with patent law.
  • We expect patent-related legal expenses to continue to fluctuate.
  • Patent litigation is inherently risky because courts may find our patents invalid, not infringed, or unenforceable, and the USPTO, or other relevant patent office, may either invalidate our patents or materially narrow the scope of their claims during a reexamination, opposition or other such proceeding.
  • The enforcement of our intellectual property depends in part upon our ability to retain the best legal counsel in order to achieve favorable outcomes from litigation, and they may become conflicted out of representing us.
  • We may experience delays in successful prosecution, enforcement, and licensing of our patent portfolio.
  • Risks Related to our Energy Operations Business and Industry
  • If oil and natural gas prices decline from current levels, or if there is an increase in the differential between the NYMEX-WTI and NYMEX-Henry Hub or other benchmark prices of oil and the wellhead price we receive for our production, our cash flows from our Energy Operations Business will decline.
  • If commodity prices decline from current levels, production from some of Benchmark’s assets may become uneconomic and cause write downs of the value of its properties, which may adversely affect its ability to borrow, its financial condition and its ability to make distributions.
  • The oil and natural gas industry and the broader U.S. economy have experienced higher than expected inflationary pressures in recent years related to increases in oil and natural gas prices, continued supply chain disruptions, labor shortages and geopolitical instability, among other pressures. Should these conditions persist, it may impact our Energy Operations Business’ ability to procure services, materials and equipment on a cost-effective basis, or at all, and, as a result, our business, financial condition, results of operations and cash flows could be materially and adversely affected.
  • Our Energy Operations Business’s hedging strategy may be ineffective in mitigating the impact of commodity price volatility on cash flows, which could adversely affect its financial condition.
  • Our Energy Operations Business’s hedging activities could result in cash losses and may limit the prices it would otherwise realize for production, which could reduce cash flows from operations.
  • Our Energy Operations Business’s hedging transactions expose it to counterparty credit risk and involve other risks.
  • Unless Benchmark replaces the oil and natural gas reserves it produces, its revenues and production will decline, which would adversely affect its cash flows from operations.
  • Producing oil and natural gas is a costly and high-risk activity with many uncertainties that could adversely affect our Energy Operations Business’s activities, financial condition or results of operations.
  • Estimated proved reserves and future production rates are based on many assumptions that may prove to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of the estimated reserves of our Energy Operations Business.
  • Any acquisitions completed by our Energy Operations Business are subject to substantial risks that could adversely affect financial conditions and operational results.
  • Currently, our producing properties are concentrated in the Anadarko Basin, making us vulnerable to risks associated with operating in a limited number of geographic areas.
  • Our Energy Operations Business is primarily dependent upon a small number of customers for production sales and may experience a temporary decline in revenues and production if it loses any of those customers.
  • Our Energy Operations Business might be unable to effectively compete with larger companies, which might adversely affect its business activities, financial condition and operational results.
  • Many of our Energy Operations Business’s leases are in areas that have been partially depleted or drained by offset wells.
  • Our Energy Operations Business’s revolving credit facility has restrictions and financial covenants that may restrict its business and financing activities.
  • The operations of our Energy Operations Business are subject to operational hazards and unforeseen interruptions for which it may not be adequately insured.
  • Benchmark is not the operator of all of our oil and natural gas properties and therefore we are not in a position to control the timing of development efforts, the associated costs or the rate of production of the reserves on such properties.
  • Oil and natural gas production operations, especially those using hydraulic fracturing, are substantially dependent on the availability of water. Our ability to produce natural gas, oil and NGL economically and in commercial quantities could be impaired if we are unable to acquire adequate supplies of water for our operations or are unable to dispose of or recycle the water resulting from our operations economically and in an environmentally safe manner.
  • Our Energy Operations Business depends in part on transportation, pipelines and refining facilities owned by others. Any limitation in the availability of those facilities could interfere with an ability to market production and could harm its business.
  • Climate change legislation, regulatory initiatives and litigation could result in increased operating costs and reduced demand for the oil and natural gas that our Energy Operations Business produces.
  • Regulation in response to seismic activity could increase our operating and compliance costs.
  • Rules regulating air emissions from oil and natural gas operations could result in increased capital expenditures and operating costs for our Energy Operations Business.
  • Our Energy Operations Business’s operations are subject to environmental and operational safety laws and regulations that may expose it to significant costs and liabilities.
  • Risks Related to our Industrial Operations Business
  • Our Industrial Operations Business relies, or may rely in the future, on its intellectual property and licenses to use others’ intellectual property for competitive advantage. If our Industrial Operations Business is unable to protect its intellectual property or obtain or retain licenses to use other’s intellectual property, or if it infringes upon or are alleged to have infringed upon others’ intellectual property, it could have a material adverse effect on our Industrial Operations Business’s financial condition, business and results of operations.
  • Our Industrial Operations Business’s inability to develop new products and enhance existing products to meet customer product requirements on a cost competitive basis may negatively impact operational results.
  • Our Industrial Operations Business is dependent on a limited number of customers to derive a large portion of its revenue, and the loss of one of these customers may adversely affect its financial condition, business and operational results.
  • Our Industrial Operations Business has limited suppliers for key product components and services and any interruption in supply could impair its ability to make and deliver its signature products, adversely affecting its business, financial condition, and operational results.
  • Failure of our Industrial Operations Business to manage inventory levels or production capacity may negatively impact its operational results.
  • Decreased consumption of supplies could negatively impact operational results of certain of our Industrial Operations Business.
  • Due to the international nature of our Industrial Operations Business, changes in a country’s or region’s political or economic conditions or other factors could negatively impact operational results.
  • Risks Related to our Manufacturing Operations Business
  • Our Manufacturing Operations Business is subject to intense competition.
  • Our Manufacturing Operations Business’s sales are dependent on purchases by large customers and any significant decline in these purchases or pressure from these customers to reduce prices could have a negative effect on future financial performance.
  • Our Manufacturing Operations Business’s operating results can be adversely affected by inflation, changes in the cost or availability of raw materials, labor, energy, transportation and other necessary supplies and services, as well as the impact of tariffs and changes in a country’s or region’s political or economic conditions.
  • Unfavorable shifts in industry-wide demand for our Manufacturing Operations Business’s products could result in inventory valuation risk.
  • Damage to our Manufacturing Operations Business’s reputation or loss of consumer confidence could have an adverse effect on our Manufacturing Operations Business.
  • Circumstances associated with divestitures and brand or product line exits could adversely affect our Manufacturing Operations Business’s results of operations and financial condition.
  • Our Manufacturing Operations Business could be subject to product liability claims and involved in product recalls.
  • Our Manufacturing Operations Business’s indebtedness may limit its financial and operating flexibility, and our Manufacturing Operations Business may incur additional debt, which could increase the associated risks.
  • Risks Related to our Common Stock
  • Our quarterly performance may be volatile, which in turn may adversely affect the trading price of our common stock.
  • Future sales of our common stock could reduce the market price of our common stock.
  • Delaware law and our charter documents contain provisions that could discourage or prevent a potential takeover of our company that might otherwise result in our stockholders receiving a premium over the market price of their shares.
  • We do not currently intend to pay dividends on our common stock in the foreseeable future, and consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.
  • Starboard’s sale of Company securities may adversely affect the market price of our common stock.
  • We agreed to certain Governance Provisions with Starboard.

Legal proceedings

In the ordinary course of business, we or our various businesses and operations are the subject of, or party to, various pending or threatened legal actions, including various counterclaims in connection with patent enforcement activities. We believe that any liability arising from these actions will not have a material adverse effect on our consolidated financial position, operational results or cash flow. For information regarding certain pending litigation, see Note 16 to our consolidated financial statements.

Our Intellectual Property Operations Business is often required to engage in litigation to enforce its patents and patent rights. Certain of its operating subsidiaries are parties to ongoing patent enforcement related litigation, alleging infringement by third parties of certain of the patented technologies owned or controlled by its operating subsidiaries.

In connection with any of its patent enforcement actions, it is possible that a defendant may claim and/or a court may rule that our Intellectual Property Operations Business has violated statutory authority, regulatory authority, federal rules, local court rules, or governing standards relating to the substantive or procedural aspects of such enforcement actions. In such event, a court may issue monetary sanctions against it or its operating subsidiaries or award attorney’s fees and/or expenses to a defendant(s), which could be material, and if required to be paid by it or its operating subsidiaries, could materially harm its operating results and its financial position.
