We offer various software platforms (“Platform” or “Platforms”) that are typically sold to corporate, academic, government and individual researchers as cloud-based SaaS via auto-renewing license agreements. Corporate, academic, and government customers typically sign up under annual or multi-year agreements paid annually in advance. Individual researchers can sign up under an annual or a month-to-month agreement and are typically billed monthly. Our Platforms also facilitate the sale of published scientific, technical, and medical (“STM”) content sold as individual articles (“Transactions”) either stand alone or via one or more of the research Platform solutions we provide. When one or more of the Platform solutions are used to purchase Transactions, customers pay for those transactions through monthly billing or via credit card for individual researchers.
They also typically deliver a return on investment to the customer by reducing the amount of time it takes a research organization to find, acquire and manage content, in addition to also driving down the ultimate cost per article and overall research costs over time. Platforms Our cloud-based SaaS Platforms consist of proprietary software and Internet-based interfaces sold to customers through an annual or monthly subscription fee. Legacy functionality falls into three areas. Discovery Tools – Our Scite.ai and Resolute.ai solutions facilitate search (discovery) across virtually all STM articles available. These solutions include basic search solutions and advanced search tools. These tools allow for searching and identifying relevant research and then purchasing that research through one of our other solutions.

ADP Indemnity provides workers’ compensation and employer's liability deductible reimbursement insurance protection for PEO Services’ worksite employees up to $1 million per occurrence. PEO Services has secured a workers’ compensation and employer’s liability insurance policy that caps the exposure for each claim at $1 million per occurrence and has also secured aggregate stop loss insurance that caps aggregate losses at a certain level in fiscal years 2012 and prior from an admitted and licensed insurance company of AIG. We utilize historical loss experience and actuarial judgment to determine the estimated claim liability, and changes in estimated ultimate incurred losses are included in the PEO segment.
Additionally, starting in fiscal year 2013, ADP Indemnity paid premiums to enter into reinsurance arrangements with ACE American Insurance Company, a wholly-owned subsidiary of Chubb Limited (“Chubb”), to cover substantially all losses incurred by the Company up to the $1 million per occurrence related to the workers’ compensation and employer's liability deductible reimbursement insurance protection for PEO Services' worksite employees. Each of these reinsurance arrangements limits our overall exposure incurred up to a certain limit. The Company believes the likelihood of ultimate losses exceeding this limit is remote. During fiscal 2025, ADP Indemnity paid a premium of $276 million to enter into a reinsurance arrangement with Chubb to cover substantially all losses incurred by ADP Indemnity for the fiscal 2025 policy year up to $1 million per occurrence.

By integrating organization tools with instant access to millions of scholarly articles, our References solution streamlines the research workflow and enhances productivity for scientific professionals. AI models are integral to powering the unique insights our platforms provide as well as the user experience customers enjoy. Natural language processing (“NLP”) and AI models are used to enhance metadata, define connections between topics and content items as well as to generate data and metrics employed to enable users to rapidly identify and understand the value of content they need for their research. We also use state of the art AI models, such as Large Language Models to include Generative AI “assistants” in several parts of the research workflow today and will continually add capability as we move forward.
Today we employ Generative AI technologies as a basis for our recommendation engine in our Discovery Tools, Access, and Manage Platform solutions. In addition, Generative AI based “assistants” in some of our solutions allow the researcher to ask questions about articles, groups of articles (folders), and more. We also have the capability to provide near full text search on STM content in the Scite.ai solution where the publisher gives us the rights to do so. The ability to not only mine an article’s full text but also show snippets of full text is unique to our Company and allows our Generative AI assistants to provide highly accurate results with a very low incidence of hallucinations as part of a Retrieval Augmented Generation framework focused just on STM content.

We leverage our Platforms efficiencies in scalability, stability and development costs to fuel rapid innovation and to gain a competitive advantage. Transactions We provide our researchers with a single source to the universe of published STM content that includes over 200 million existing STM journal articles for instant download, 50 million journal articles for rent, 10 million online book chapters, and 45 million only in print journal articles. In addition, we add between 2 to 4 million newly published STM articles each year. STM content is rented or sold to our customers on a per transaction basis. Researchers and knowledge workers in life science and other research-intensive organizations generally require single copies of published STM journal articles for use in their research activities.
These individuals are our primary users and while they typically purchase the articles via one of our Platform solutions, we do have some customers that just order articles from us on behalf of end-users in their organizations. Core to many of our Platform solutions is providing our customers with ways to find and download digital versions of STM articles that are critical to their research. Customers submit orders for the articles they need which we source and electronically deliver to them generally in under an hour, in most cases in seconds. This service is generally known in the industry as single article delivery or document delivery.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-11-11. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
