ITEM 1: BUSINESS
  GENERAL
 
    OVERVIEW.  HBO & Company (HBOC or the Company), incorporated in 1974,
develops integrated patient care, clinical, financial, managed care and
strategic management software solutions for the healthcare industry. These open
systems applications facilitate the integration of clinical, financial and
administrative data from a wide range of customer systems and software. HBOC's
broad product portfolio can be implemented in a variety of combinations from
stand-alone to enterprisewide, enabling customers to add incremental
capabilities to existing information systems without making prior capital
investments obsolete. HBOC also provides a full complement of network
communications technologies, including wireless capabilities, as well as
outsourcing services that are offered under contract management agreements
whereby its staff manages and operates data centers, information systems,
organizations and business offices of healthcare institutions of various sizes
and structures. In addition, the Company offers a wide range of electronic
commerce services, including electronic medical claims and remittance advice
services as well as statement processing.
 
    HBOC markets its products and services to integrated health delivery
networks, hospitals, physicians' offices, home health providers, pharmacies,
reference laboratories, managed care providers and payers. HBOC also sells its
products and services internationally through subsidiaries and/or distribution
agreements in the United Kingdom, Canada, Ireland, Saudi Arabia, Kuwait,
Australia, Puerto Rico and New Zealand.
 
    As of December 31, 1996, HBOC had 4,404 employees worldwide.
 
    INDUSTRY.  The healthcare industry continues to undergo significant and
rapid change. Healthcare delivery costs have increased dramatically in recent
years compared to the overall rate of inflation, while the growing influence of
managed care has resulted in increased pressure on participants in healthcare
systems to contain costs. Accordingly, healthcare systems are migrating toward
more managed care reimbursement, including discounted fee-for-service and
capitation. Under capitation, providers are paid a predetermined fee per
individual to provide all healthcare services, thereby assuming the potential
financial risks of escalating healthcare costs.
 
    To deliver care in a more cost-effective manner, providers are forming
integrated health delivery networks that may include acute-care hospitals,
physicians' offices, outpatient clinics, homecare, long-term care facilities and
payer entities. The success of these comprehensive delivery networks is
dependent on effectively managing and delivering information to caregivers and
managers across multiple points of care.
 
    Traditionally, the acute-care hospital market has been the largest segment
of healthcare information services. According to industry analysts, the
healthcare industry spent approximately $12 billion in 1996 for products and
services to support automated information systems. Information systems
expenditures in healthcare are expected to grow to $18 billion by the year 2000
as hospitals and other providers spend a larger percentage of their operating
budgets on systems that will enable them to provide caregivers and managers with
access to the information needed to quantify and control costs, a key mandate of
managed care.
 
    In the 1996 Annual HIMSS/HP Leadership Survey, an industry survey conducted
by Hewlett-Packard at the Healthcare Information and Management Systems Society
conference, 63 percent of the respondents stated that their information system
investments will increase at a rate of 20 percent or more over the next two
years. In addition, 32 percent of the respondents noted that their most
important information system priority was upgrading information technology
infrastructure.
 
    With the increasing prevalence of managed care and capitation, healthcare
information systems are evolving to meet new and more complex information
requirements. Initially, these systems were financially
 
                                       1
<PAGE>
oriented, focusing on the ability to capture charges and generate patient bills.
However, as reimbursement has shifted more toward risk sharing and capitation,
providers and payers needed to better manage risk by controlling costs,
demonstrating quality, measuring outcomes and influencing utilization. Because
this requires integration of clinical and financial information, systems have
evolved from processing billing information to include enterprisewide systems
capable of capturing, storing and analyzing both clinical and financial data
across the continuum of care.
 
    While the availability of a complete, timely and cost-effective
patient-focused information system is essential to providing quality care and
controlling costs, the source of patient information usually covers a number of
different sites. Therefore, current and historical paper records must be made
available by computer at all points of care. All players in the delivery network
need information systems that can capture data at the point of care, communicate
data across the continuum of care and process and store large volumes of data
necessary for the development of a lifelong computer-based patient record.
 
STRATEGY
 
    HBOC's strategy is to provide a comprehensive range of computer-based
information systems and services designed to meet the evolving needs of health
enterprises thereby enabling customers to add incremental capabilities to
existing information systems without making prior capital investments obsolete.
The key elements of this strategy are as follows:
 
    LEVERAGE THE EXISTING CUSTOMER BASE.  With one or more of its products
installed in approximately 51 percent of the community hospitals (over 100 beds)
in the United States, HBOC is a leader in the healthcare information systems
marketplace. HBOC expands its customer base through sales and marketing efforts
and through strategic acquisitions such as IBAX Healthcare Systems and First
Data Health Systems Corporation, which had 475 and 500 hospital customers,
respectively (see "Recent Acquisitions" below). This expanded customer base
offers HBOC significant opportunities to sell both additional applications of
its established product lines and its Pathways 2000-Registered Trademark-
enterprise solutions. In addition, HBOC believes its relationships with
customers and its familiarity with their existing systems give HBOC an advantage
over many of its competitors in marketing applications to meet the evolving
needs of these customers. HBOC also seeks to further leverage its relationships
with existing customers to access additional healthcare organizations throughout
newly formed health delivery networks.
 
    PROVIDE ENTERPRISEWIDE SOLUTIONS TO THE EVOLVING HEALTHCARE MARKET.  HBOC
offers one of the broadest product lines in the healthcare information systems
industry to serve patient care, clinical, financial and strategic management
needs. Through its Pathways 2000-Registered Trademark- family of enterprisewide
information systems, HBOC facilitates the more efficient integration of delivery
networks. HBOC's Pathways 2000-Registered Trademark- client/ server applications
are designed to provide a common information infrastructure that enables
organizations to collect, manage and disseminate clinically oriented information
organized on the basis of a patient's entire history of care. The Pathways
2000-Registered Trademark- product line provides the capability to create
longitudinal computerized patient records as well as connectivity along the
entire continuum of care, enabling users to access patient data from any point
within an integrated delivery system.
 
    PROVIDE SUPERIOR INTEGRATION OF PRODUCTS AND DATA.  HBOC's products offer
healthcare organizations open system solutions with the flexibility to add
incremental capabilities, which enables them to protect their capital
investments. In addition, HBOC's client/server architecture facilitates the
integration of clinical data with financial and administrative data from both
HBOC and non-HBOC applications for efficient resource allocation, allowing
organizations to benefit from price/performance advances. HBOC believes that
these features will be of key significance to its customers as they face
industry consolidation and evolve as part of integrated care delivery systems.
 
    EXPAND INTO NEW MARKETS.  HBOC strives to provide premier business-critical
applications to every essential care setting as well as to the payer market.
HBOC believes that as healthcare organizations
 
                                       2
<PAGE>
expand and decentralize, management information requirements at the point of
care will increase. HBOC is developing or has acquired client/server
applications to meet these needs in the physician's office, home health market,
reference laboratory and the payer market. Applications for other components of
the care delivery network, such as long-term care, are under consideration.
 
    CONTINUE PRODUCT DEVELOPMENT.  HBOC believes that a key to its growth is an
ongoing focus on research and development to ensure its product offerings will
continue to strive to meet the evolving needs of its existing and potential
customer base. HBOC's research efforts focus on enhancements to existing product
offerings as well as new product development. In developing products, HBOC's
goal is to ensure its information systems are highly flexible and quickly
adaptable and can serve the information access needs of an increasingly broad
range of users. HBOC's product developers use state-of-the-art application
development tools such as program generators, artificial intelligence and expert
systems, which decrease development time and lower the cost of new products.
While HBOC's efforts focus primarily on the internal research and development of
new products, HBOC has made and continues to explore strategic acquisitions of
developers of niche product software to complement and diversify its product
portfolio.

PRODUCT SUMMARY
 
    HBOC's products and services are designed to serve the information needs of
all participants in the integrated health delivery system: the caregiver, in
whatever discipline or capacity; the institution or enterprise, in whatever
aspect of its business; and the patient (increasingly referred to by healthcare
organizations as the "customer" or "member"), in whatever setting of care.
Today, the health services delivery network through which these participants
relate can include acute-care hospitals, outpatient clinics, physicians'
offices, reference laboratories, commercial pharmacies, long-term care
facilities, patients' homes and wellness centers. In addition, employers, payers
and governmental agencies play a major role in directing how healthcare
resources are deployed, which impacts capital spending by healthcare
enterprises.
 
    To serve this wide-ranging and diverse network of health delivery, HBOC
bases its offerings on a strategic mix of applications and technologies backed
by implementation, support and other services. HBOC's product portfolio is
organized into six components: acute-care or HIS (hospital information system),
infrastructure, clinical management, practice management, access management and
enterprise management. In addition, HBOC offers a suite of services that allows
healthcare organizations the flexibility to select the level of resources that
most effectively serves their needs.
 
    HIS -- HIS applications automate the operation of individual departments and
their respective functions within the inpatient environment. These
hospital-based transaction and decision support systems form the core of systems
that, in conjunction with other tools designed to directly support clinical
decision-making, help streamline the care process over the continuum of care.
HBOC's HIS systems include applications for patient care, laboratory, pharmacy,
radiology, financials and management decision-making.
 
    INFRASTRUCTURE -- Infrastructure applications are not limited to a single
department or function; rather, they form the foundation of the emerging
information structures of health enterprises. HBOC's wide array of networking
and database applications provide the key elements for integrating and uniting
providers across the continuum of care. Components include local, wide area and
value-added networks, as well as wireless technology and electronic data
interchange (EDI) capabilities. An interface manager coordinates the flow of
information, often from disparate sources, throughout the entire system, and a
data repository stores patient information for access throughout the enterprise.
In bringing the enterprise together, these solutions establish the physical
basis for a lifelong patient record.
 
    CLINICAL MANAGEMENT -- Clinical applications facilitate and improve the
actual practice of medicine in a variety of care settings, whether hospital,
physician office, home or clinic. Drawing from a common database of patient
information, computer technology gives professionals immediate access to the
critical information necessary to provide better quality care wherever they are
in the delivery system. HBOC's point-of-care applications allow physicians and
other clinicians to document patient information, establish and manage
guidelines or standards of care, enter and manage orders, and view all results
and clinical information. These clinical solutions support the need for
collaboration among multiple disciplines and for integration with other
information systems in the health delivery network.
 
    PRACTICE MANAGEMENT -- Practice management applications provide a
comprehensive solution for medical groups and physician enterprises, whether
they are independent or part of an integrated health network. With business
office management as its cornerstone, HBOC's practice management solution gives
physician groups or enterprises the flexibility to manage their business under
many different organizational and reimbursement models. Also included are risk
management and managed care capabilities, clinical systems for managing patient
care, and scheduling that can handle multiple providers, facilities, and
equipment within the enterprise. Additional capabilities to help accelerate cash
flow, reduce costs, and increase productivity include decision support, data
quality analysis and EDI.
 
                                       4
<PAGE>
    ACCESS MANAGEMENT -- Access management solutions allow the healthcare
organization's "customers" to access health services more easily and
cost-effectively. Indexing applications organize the vast information collected
about a person throughout the enterprise, allowing patients to be tracked and
information about them to be accessed wherever they go for care. Scheduling
systems instantly register and schedule patients anywhere in the enterprise, as
well as the resources needed to serve them. Other system capabilities allow for
information tied to specific episodes of care to be collected and managed.
Besides increasing accuracy, these applications help alleviate patient
frustration with having to provide duplicate information from one setting of
care to another thereby enhancing "customer satisfaction."
 
    ENTERPRISE MANAGEMENT -- Enterprise management applications facilitate and
improve the management and operation of all aspects of the health enterprise --
for payers as well as provider. These applications focus on providing managers
with the clinical, financial and other information necessary to contain costs
while ensuring high-quality care. Examples include utilization management and
accounts receivable management, as well as managed care contracting and member
management applications.

Packard Co., and IBM Corp.

    Most of the Pathways 2000-Registered Trademark- and HIS products in HBOC's
product portfolio are offered internationally. In addition, products added to
the HBOC product line with the acquisition of Data-Med Computer Services Limited
in December 1993 are available in the United Kingdom. In most cases, the
applications offered internationally have been customized or developed to meet
the particular needs of the country in which they are implemented.
 
SERVICES
 
    Installation and implementation services are provided for purchasers of all
HBOC software products to assist with the smooth introduction of or transition
to those products. HBOC also provides software maintenance and enhancement
services, as well as custom programming and system modifications to meet special
customer requirements. Equipment maintenance services are provided by HBOC or

RESEARCH AND DEVELOPMENT
 
    The Company's product development effort applies advanced computer
technology and installation methodologies to specific information processing
needs of hospitals. The Company believes a substantial and sustained commitment
to such research and development (R&D) is important to the long-term success of
the business.
 
    Investment in software development, including both R&D expense as well as
capitalized software, has increased as the Company has addressed new software
applications and enhanced existing products for installed systems. The Company
expensed $90 million (11% of revenue) for R&D activities during 1996, as
compared to $79 million (13% of revenue) and $62 million (14% of revenue) during
1995 and 1994, respectively. The Company capitalized 29%, 31% and 31% of its R&D
expenditures in 1996, 1995 and 1994, respectively.
 
    Information regarding R&D is included in the schedule "Five-Year Selected
Financial Information" on page 5 of the Annual Report and under the caption
"Capitalized Software" and under the caption "Nonrecurring Charges" in Note 1 of
"Notes to Consolidated Financial Statements" on pages 16 and 17 of the Annual
Report, a copy of which is included as an exhibit to this Form 10-K and is

COMPETITION
 
    HBOC experiences substantial competition from many firms, including other
computer services firms, consulting firms, shared service vendors, certain
hospitals and hospital groups, and hardware vendors. Competition varies in size
from small to large companies, in geographical coverage, and in scope and
breadth of products and services offered.
 
    Although some of the Company's competitors are comparable in size to the
Company, the Company believes that few, if any, competitors offer a comparable
range of healthcare information systems and services that compare favorably with
respect to all of the competitive criteria, mainly price and service.
 
FACTORS AFFECTING FORWARD-LOOKING STATEMENTS
 
    This report, and other reports, proxy statements and other communications to
stockholders, as well as oral statements made by representatives of the Company,
may contain forward-looking statements with respect to, among other things, the
Company's future revenues, operating income and earnings per share, as well as
plans and objectives of management. The following are some, but not necessarily
all, of the factors that may cause the Company's actual results to vary
materially from those which are the subject of any such forward-looking
statements.
 
    An important element of HBOC's business strategy has been and will continue
to be expansion through acquisitions, both to extend its customer base and to
acquire strategic technology. The Company's ability to expand successfully
through acquisitions depends on many factors including the identification of
appropriate acquisition opportunities, negotiation of suitable terms and
management's ability to effectively integrate and operate the acquired
businesses. The Company competes for acquisitions with other companies, certain
of which have significantly greater financial and management resources. HBOC's
financial performance will be subject to the risks of the performance of the
acquired businesses as well as the financial effects associated with integration
of such businesses.
 
    The healthcare industry is subject to changing political, economic and
regulatory influences, many of which relate to control of healthcare costs. Such
changes may affect operational aspects of the healthcare industry, including
procurement practices and the availability and/or allocation of capital funds,
which could result in greater selectivity, thus adversely impacting HBOC's
ability to sell its products. HBOC cannot predict with any certainty what
impact, if any, future regulation or healthcare reform might have on its results
of operations, financial condition or business.
 
    While HBOC maintains insurance protecting against certain asserted claims,
there can be no assurance that its insurance coverage would adequately cover any
such claims asserted against HBOC.
 
    Competition in the Company's industry is subject to continual change in not
only the products and services offered but also in the manner in which vendors
are selected by customers. Accordingly, HBOC's
 
                                       9
<PAGE>
continued success will be dependent on its ability to develop new products and
services on a timely basis and at competitive prices.
 
    The Company must anticipate and adapt to evolving industry standards and new
technological developments. The market for the Company's products is
characterized by continued and rapid technological advances. HBOC's future
success will depend in part on its ability to be responsive to these
technological developments and challenges, which could also lower the cost of
products and services or otherwise result in competitive pricing pressures.
 
    HBOC relies on a combination of trade secret, copyright and trademark laws,
together with nondisclosure, other contractual provisions and technical measures
to protect its proprietary rights in its products. There can be no assurance
that these protections will be adequate or that HBOC competitors will not
independently develop technologies that are equivalent or superior to HBOC's
technology. Although the Company believes that its products and other
proprietary rights do not infringe upon the proprietary rights of third parties,
there can be no assurance that third parties will not assert infringement claims
against the Company in the future.
 
    The stock market has, from time to time, experienced extreme price and
volume fluctuations, particularly in the high technology sector, which have
often been unrelated to the operating performance of particular companies. HBOC
experiences fluctuations in its stock price related to these general market
swings as well as announcements of technological innovations, new product
introductions by HBOC or its competitors, market conditions in the computer
software or hardware industries and healthcare reform measures. These
fluctuations may adversely effect the Company's ability to make acquisitions
utilizing its stock.

LETTER TO STOCKHOLDERS
- --------------------------------------------------------------------------------

BUILDING ON THE MOMENTUM OF THE PAST FEW YEARS, HBOC REACHED A NEW LEVEL OF
INDUSTRY LEADERSHIP IN 1996 -- NOT ONLY IN FINANCIAL PERFORMANCE BUT IN CUSTOMER
GROWTH AND LEADING-EDGE SOFTWARE SOLUTIONS TO ADDRESS THE BROAD CONTINUUM OF
HEALTHCARE DELIVERY.

Revenue grew by 31 percent last year to $797 million, and earnings per share 
increased 63 percent to $1.19 excluding acquisition-related nonrecurring 
charges.  HBOC more than doubled its customer base through expansion into 
three new markets -- physicians, homecare and payers.  We added 150 new 
Pathways 2000 -Registered Service Mark- enterprise solution customers.  We 
signed five new outsourcing contracts and extended three existing 
engagements.  We introduced Paragon -Registered Service Mark- a Windows NT 
- -Registered Trademark- product for the small-hospital market, and we rolled 
out CarePoint 2000 -Registered Service Mark-, HBOC's fourth-generation 
wireless technology product line.  The HBOC DeskTop gave product users single 
sign-on and easy access to applications.  And a 14-chapter HL7 standards 
document set the bar for internal product integration, a vital step in making 
integration Job No. 1 at HBOC.

Those are just a few of our accomplishments last year, and we expect 1997 to be
even better as the demand grows for new software solutions to address changing
information requirements.  Healthcare restructuring shows no signs of slowing
down, and the movement from fee-for-service to managed care is driving
consolidations, affiliations and alliances within and across market segments.

EXECUTIVE OFFICER

Care delivery is rapidly moving beyond the bounds of hospitals and physicians'
offices to settings such as community clinics and patients' homes.  The
traditional lines among payers, providers and physician practices have become
increasingly blurred as integrated deliver networks evolve to manage the health
of populations.  And the ability to capture clinical information at the point of
care has taken center stage as organizations of all kinds -- hospitals, health
enterprises, physician practices, home health agencies and payers -- seek to
manage outcomes and lower costs.

There has never been a more exciting time in healthcare or a greater
opportunity for HBOC.  Building on our presence in the hospital information
systems market, we've systematically extended our reach into the health
enterprise at large with strategic solution sets and "best-of-class" clinical
practice software tools for hospital, physician office and homecare settings.
Along the way, though internal growth and acquisitions, HBOC has assembled more
than 225

                                    -3-

LETTER TO STOCKHOLDERS

employee clinicians (including more than 40 physicians), more than 1,500
clinical customers and some 4,000 voting members in its clinical user groups.

Working together with customers, HBOC employees are drawing from firsthand
experience to develop new solutions that can help health enterprises make a
dramatic impact on cost and quality as they arrange for care, provide care and
account for care across the enterprise.  HBOC's access management solutions
enable organizations to re-engineer the way members access healthcare, providing
them with consistent, coordinated access to services through streamlined
registration and a universal identifier.  Our clinical practice tools are
specially designed for use at the point of care, increasing both the efficiency
of caregivers and the accuracy of the information they use to make decisions.
And HBOC's enterprise management solutions--from decision support to full-blown
managed care--enable enterprise managers to account for resources, determine how
effectively those resources have been used and set a course for the future.

HBOC further strengthened its product portfolio in 1996 by expanding its
presence in three market segments that offer great potential and that are
relatively new to us--physicians, homecare and payers.  The acquisition of
CyCare Systems, Inc., places HBOC squarely in the physician market with a proven
solution, while Management Software, Inc., gives HBOC market share leadership in
homecare.  The addition of GMIS Inc. provides HBOC with 280 payer customers--
including some of the largest and best-known insurance companies in the United
States--and greater resources to address not only the needs of payers but also
providers that are assuming risk for a population.

Each of these additions represents a twofold opportunity for HBOC--the addition
of new customers and new revenue streams, and the ability to offer new solutions
to existing customers.  With the increasing prevalence of managed care, a great
majority of our customers are ripe for enterprisewide solutions and look to HBOC
for not only broad range and rich functionality but full integration as well.

In that respect, HBOC has stepped up to a challenge that few others have the
ability or resources to tackle.  Integration continues to be Job No. 1 at HBOC--
not only among our products but among our people and processes as well.  We made
steady progress last year, publishing standards that all R&D groups follow to
ensure HBOC products share data at the level required for full integration.
Phase II of the HBOC DeskTop is now operational at development sites, and our
sales, development, service and support groups moved from a product-line,
business-unit organizational structure to one focused on providing integrated
solutions for the health enterprise as a whole.

HBOC faces many challenges in 1997--among them rapid change, competitive
pressures and the continued challenge of assimilating new products and employee
groups.  But we've set the bar high for ourselves and we intend to "take the
lead" as never before--with a solid customer base, talented employees, a healthy
balance sheet and the broadest range of products and services in the industry.

                              FINANCIAL REVIEW

GENERAL

Unless stated otherwise, all expense, income and per share amounts exclude 
the following nonrecurring charges and include the dilutive effect of stock 
options: $61.4 million related primarily to the acquisitions of CyCare 
Systems, Inc., Management Software, Inc., and GMIS Inc., in 1996; $136.5 
million related primarily to the 1995 acquisitions of First Data Health 
Systems Corporation (now known as the Charlotte Product Group or CPG) and 
CliniCom Incorporated.  Each of the above 1996 acquisitions and the 1995 
acquisition of CliniCom Incorporated was accounted for as a pooling of 
interests; therefore, all prior period financial information has been 
restated.  Unless otherwise noted, management's discussion of financial 
results is based on restated figures.

Once again in 1996, HBO & Company ("the Company" or "HBOC") achieved record 
revenue and earnings.  For 1996, the Company posted earnings per share of 
$1.19, a 63% increase over earnings per share of $.73 for 1995.  The 
significant increase in earnings per share resulted from strong revenue 
growth, $796.6 million in 1996 up from $607.2 million in 1995, an increase of 
31%, and an increase in operating income as a percent of revenue to 23% in 
1996 compared to 17% in 1995.  Including the nonrecurring charges and 
excluding the dilutive effect of stock options (for 1995), earnings per share 
for 1996 was $.79, compared to a loss per share of ($.21) in 1995 and 
earnings per share of $.44 in 1994.

The Company's operating expense continued to grow at a slower rate than 
revenue due to increased software sales, successful cost-control programs and 
productivity enhancements.  The Company continues to make progress in the 
area of employee productivity, with 1996 revenue per average number of 
employees of $184,000, an increase from $156,000 for 1995 and $144,000 for 
1994.

As the healthcare industry moves from a fee-for-service environment to 
managed care, HBOC has evolved the focus of its products beyond hospital and 
acute-care settings to encompass the full spectrum of care, including 
physician practices, homecare and payer entities.  The Company's strategic 
solutions sets are aimed at supporting the re-engineering of various 
healthcare-related activities to improve efficiencies, reduce costs and 
improve the quality of patient care.  Because HBOC realizes that most health 
enterprises and integrated delivery networks must integrate diverse 
technologies from disparate systems, the Company continues to focus on data 
and product integration.  The Company's revenue growth is the result of its 
ability to develop, implement and support patient care, clinical, financial, 
homecare, managed care, payer and strategic management software that 
facilitates the integration of data throughout the enterprise and across the 
continuum of care.

In 1996, the Company completed the acquisitions of CyCare Systems, Inc. 
(CyCare), Management Software, Inc. (MSI), and GMIS Inc. (GMIS).  These 
strategic acquisitions have expanded the Company's product and customer base 
into markets that had previously been largely untapped by the Company.  
Revenue and operating income for all three of the acquired business groups 
increased significantly in 1996 compared to 1995, demonstrating HBOC's 
ability to leverage its strong sales and distribution network and quickly 
introduce new products into its broad portfolio of product and service 
offerings.

The Company ended 1996 with a strong backlog.  At December 31, 1996, there 
were 172 units of system sales not yet delivered and installed totaling $57.9 
million in revenue along with $42.7 million of future recurring software 
revenue.  Future contracted outsourcing fees totaled $120.6 million, and 
future payments under monthly service fee agreements totaled $3.3 million.  
In addition, the Company derives significant revenue from maintenance and 
support contracts that are automatically renewable unless canceled, as well 
as recurring revenue from multiyear remote and electronic processing 
contracts.

The Company continues to maintain a strong liquidity position.  Cash and 
short-term investments grew to $183.6 million at December 31, 1996, from 
$91.8 million at December 31, 1995.  Cash flow from operations was $136.9 
million for 1996,  $73.8 million of cash was utilized in investing activities 
and $10.7 million of cash was provided by net financing activities.  HBOC 
financed all 1996 acquisitions through equity or with cash from operations 
and had no bank debt as of year-end.

<PAGE>

YEARS ENDED DECEMBER 31, 1996 AND 1995
Revenue increased 31% to $796.6 million in 1996 from $607.2 million in 1995. 
This growth was mainly due to significant increases in sales of enterprise 
client/server systems, HIS (hospital information systems), hardware and 
services.

One-time software license fee revenue grew 51% to $204.8 million in 1996, 
compared to $135.3 million in 1995.  One-time software revenue as a percent 
of total revenue increased to 26% in 1996 compared to 22% in 1995.  These 
increases were primarily due to the continuing strong demand for the Pathways 
2000-Registered Trademark- line of enterprise solutions.  In addition, the 
Company recognized strong sales of STAR 2000 and decision support products.  
GMIS recurring software revenue increased due to strong sales of data quality 
products to the payer market.

Hardware revenue increased 46% to $126.0 million for 1996 compared to $86.2 
million for 1995.  As a percent of total revenue, hardware revenue increased 
to 15% in 1996 compared to 14% in 1995.  These increases were primarily from 
the strong sales of RISC-based processors sold in conjunction with 
software, sales of network equipment through the Connect Technology Group, 
demand for the Company's CarePoint 2000-SM- wireless solution and a continuing 
effort to increase add-on hardware sales to existing customers through an 
expanded sales center.  The Company continues to support an open systems 
approach with the ability to support multiple networking options as well as 
the leading hardware platforms.

Implementation and other services revenue increased 24% in 1996 over 1995 and 
represented 15% of total revenue in 1996 compared to 16% in 1995.  The 
revenue increase primarily reflects the increase in implementations resulting 
from strong system sales and the full-year results of CPG, which was acquired 
by purchase in June of 1995.  The Company continues to invest in programs 
designed to streamline the implementation process by giving customer 
organizations more control over their implementations and the extent of HBOC 
involvement.  As a result, the productivity of the Company's implementation 
personnel has continued to improve.

Maintenance and support revenue increased 19% in 1996 over 1995 and 
represented 23% of total revenue in 1996 compared to 25% in 1995.  The 
increase for 1996 was primarily due to growth in existing product lines, 
expansion of the customer base and the inclusion of CPG maintenance for a 
full year in 1996.  To manage this growth, the Company introduced a 
companywide support system, SAGE, in the second quarter of 1996 and is in the 
process of implementing it for the entire employee and customer base.

Remote and electronic processing revenue increased 31% in 1996 compared to 
1995 due to the full-year impact of CPG.  In addition, outsourcing services 
revenue increased 16% in 1996, due to the addition of new outsourcing sites.

Cost of operations as a percent of revenue decreased to 44% in 1996 from 47% 
in 1995.  This percentage decrease was mostly in the area of personnel 
expense resulting from employee productivity enhancements.  Total hardware 
cost as a percent of revenue increased to 12% in 1996 from 11% in 1995.  In 
conjunction with decreases in cost of operations as a percent of revenue, the 
gross margin for 1996 grew to 56% from 53% in 1995.  Cost of operations 
expense increased 23% in 1996 primarily due to increased hardware costs 
associated with the growth in hardware sales, increased software royalties 
expense due to increases in software sales and increased personnel expense 
due to the overall growth of the Company.  In addition, cost of operations 
expense increased due to 1995 acquisitions, including costs associated with 
the CPG remote processing data center, software and hardware maintenance 
expense and amortization of intangibles.

Marketing expense as a percent of revenue decreased slightly to 14% for 1996 
from 15% for 1995.  Marketing expense increased 27% in 1996 over 1995, 
primarily due to higher personnel and commission expense directly related to 
the growth in size and revenue of the Company.

Research and development (R&D) expense as a percent of revenue decreased 
slightly to 8% in 1996 compared to 9% in 1995.  The R&D capitalization rate 
decreased to 29% in 1996 from 31% in 1995.  The R&D capitalization rate 
decreased due to a reduction in the use of consultants and efforts to 
capitalize projects acquired with CyCare, MSI, and GMIS under more 
conservative HBOC policies.  Actual R&D expense increased 19%, mainly due to 
R&D related to 1995 acquisitions and additional personnel for new product 
development.

General and administrative (G&A) expense as a percent of revenue decreased to 
11% for 1996 compared to 12% for 1995, as the Company continued to leverage 
its fixed costs against its growing revenue.  Actual G&A expense increased in 
1996 primarily due to increased facilities costs and increased personnel 
expense due to acquisitions and growth of the Company.  

                                -7-
<PAGE>

Total operating income as a percent of revenue increased significantly to 23% 
in 1996 from 17% in 1995.  This is the result of increased sales of 
high-margin software and services, and a continuing effort to increase the 
efficiency of operations and personnel.

YEARS ENDED DECEMBER 31, 1995 AND 1994
Revenue in 1995 increased 34% over 1994 due to increases in revenue from 
maintenance contracts, software license fees and the addition of remote 
processing revenue from the purchase of CPG.  For 1995, cost of operations 
expense as a percent of revenue decreased to 47% from 50% in 1994.  This 
decrease was mainly due to the shift in revenue mix from lower-margin 
hardware revenue to higher-margin software and services revenue.  Total cost 
of operations expense increased over 1994 primarily due to higher personnel 
expense, higher hardware costs and software royalty fees, and increased 
facilities expense.  Cost of operations expense also increased due to costs 
associated with acquisitions such as increased amortization and the costs of 
the CPG remote data processing center.

Marketing expense as a percent of revenue increased to 15% for 1995 from 14% 
for 1994.  Marketing expense increased in 1995 over 1994, primarily due to 
higher personnel and commission expense directly related to the growth in 
size and revenue of the Company.

R&D expense as a percent of revenue remained constant at 9% for 1995 and 
1994.  The R&D capitalization rate remained stable at 31% for 1995 and 1994.  
Actual R&D expense increased in 1995 mainly due to higher personnel expense 
related to acquisitions.

G&A expense as a percent of revenue decreased to 12% for 1995 compared to 14% 
for 1994, as the Company continued to realize synergies from acquisitions.  
Actual G&A expense increased in 1995 primarily due to increased facilities 
costs and increased personnel expense due to acquisitions and growth of the 
Company.

Total operating income as a percent of revenue increased significantly to 17% 
in 1995 from 13% in 1994.  This is the result of increased sales of 
high-margin software and a continuing effort to increase efficiency of 
operations and personnel.

NONRECURRING CHARGES

HBOC recorded nonrecurring charges of $61.4 million in 1996 related to the 
pooling acquisitions of CyCare, MSI and GMIS, and the purchase acquisition of 
Gemini Ltd., in the United Kingdom.  In the third quarter, a $26.2 million 
charge was taken for CyCare and MSI, and in the fourth quarter, a $34.4 
million charge was taken for GMIS.  These charges consisted mainly of the 
write-down of long-lived assets of $30.0 million, transaction costs of $11.4 
million, severance and employee-related costs of $6.3 million and other 
product-related costs of $12.9 million.

In 1995, the Company recorded nonrecurring charges totaling $136.5 million 
primarily related to the purchase acquisition of CPG and the pooling 
acquisition of CliniCom Incorporated.  These charges consisted mainly of 
purchased research and development costs related to the purchase of CPG, 
severance and other acquisition costs.

TAXES
Including the nonrecurring charges, the effective tax rate for 1996 was 40% 
compared to 45% for 1995 and 37% for 1994.  A comparison of the 1995 and 1994 
effective rates is affected by the pooling acquisition of MSI, which was a 
Subchapter S corporation and therefore did not provide for corporate taxes on 
a historical basis.

SHARES

Fully diluted weighted average shares outstanding increased in 1996 from 
1995 due to shares issued under employee stock option and purchase programs 
and the dilutive effect of stock options.  Weighted average shares 
outstanding increased in 1995 from 1994 due to the issuance of shares in 
connection with the purchase of CPG and shares issued under employee stock 
option and purchase programs.

INFLATION
HBOC is affected by inflation through increased salaries, benefits and other 
operating and administrative expenses.  To the extent permitted by the 
marketplace, the Company attempts to pass on increasing costs by periodically 
increasing prices of products and services.  Standard software maintenance 
and support agreements contain clauses allowing the Company to increase fees 
annually to reflect changes in costs.  Other products and services are 
generally contracted for short periods and are therefore not exposed to 
inflationary pressure.

LIQUIDITY AND CAPITAL RESOURCES
The Company continues to improve the strength and quality of its balance 
sheet.  At December 31, 1996, HBOC had $183.6 million in cash and short-term 
investments compared to $91.8 million at December 31, 1995.  With strong cash 
and liquid assets, no bank debt and an improving current ratio, the Company 
remains well-positioned for continued growth.

                                      -8-
<PAGE>


During 1996, the Company generated $136.9 million in cash flow from 
operations, used $73.8 million in investing activities and provided $10.7 
million from net financing activities.  As a result of this cash activity, 
the Company's cash balance increased 85% to $160.4 million at December 31, 
1996, from $86.6 million at December 31, 1995.  During 1996, the Company paid 
off all pre-acquisition, long-term debt of CyCare and MSI.

The Company's current ratio increased to 1.64:1 at December 31, 1996, from 
1.37:1 at December 31, 1995.  Current assets increased $209.3 million, mainly 
reflecting increases in receivables and cash.  The Company's management 
places a high priority on the area of receivables, and the Company continues 
to maintain a low delinquency rate.  Current liabilities increased $89.5 
million due to an increase in customer deposits, deferred revenue, income 
taxes payable and acquisition accruals related to the nonrecurring charges.

The Company has access to several financing sources, including a $5 million 
line of credit and a $30 million revolving credit agreement.  As of December 
31, 1996, there were no outstanding balances on either.  Management believes 
that the Company's cash flow from operations and amounts available under 
existing credit arrangements are sufficient to meet ongoing operational and 
capital expenditure requirements, as well as to fund costs associated with 
future equity acquisitions and small acquisitions for cash.

All prior period amounts have been restated to reflect the 1996 acquisitions

transactions.

(1) The total of the four quarterly amounts for earnings (loss) per share for 
    the year may not equal the earnings (loss) per share amount for the year 
    in total. Differences can result from the use of a weighted average to
    compute the weighted average shares outstanding for each quarter and the
    year. Differences are also caused by the exclusion of common stock 
    equivalents from the calculation of primary and fully diluted weighted 
    average shares outstanding in periods in which there is a loss. In the case
    of 1995, the common stock equivalents are anti-dilutive.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION
The consolidated financial statements include the accounts of HBO & Company 
and its wholly owned subsidiaries, collectively referred to as "the Company" 
or "HBOC."  All significant intercompany transactions and balances have been 
eliminated in consolidation.  Certain previously reported amounts have been 
reclassified to conform to current presentation.

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amounts of revenue and expense during the reporting period.  
Actual results could differ from those estimates.

REVENUE RECOGNITION
HBO & Company delivers enterprisewide patient care, clinical, financial, 
managed care, payer and strategic management software solutions, as well as 
networking technologies, electronic data interchange, outsourcing and other 
services to healthcare organizations throughout the world.

Systems -- Information systems are marketed under equipment purchase and 
software license agreements, as well as service agreements.  One-time 
software and hardware revenue is generally recognized at the time of 
delivery.  The Company also licenses software under multiyear agreements for 
which revenue is recognized on an annual basis.  There are no significant 
vendor obligations remaining, and collection is probable when revenue is 
recognized.

Services -- Implementation fees are recognized as the work is performed or on 
a percentage-of-completion basis.  Maintenance and support agreements are 
marketed under annual and multiyear agreements and are recognized ratably 
over the period covered by the agreements.  Electronic data interchange and 
remote processing services are recognized monthly as the work is performed.  
Outsourcing services are recognized as the work is performed or on a 
percentage-of-completion basis.

The American Institute of Certified Public Accountants has issued an exposure 
draft concerning revenue recognition in the software industry that seeks to 
clarify certain issues under Statement of Position (SOP) 91-1.  The draft SOP 
is expected to become effective during 1998.  The Company has reviewed the 
exposure draft and, as it is currently written, does not anticipate any 
change to its revenue recognition policy as a result of the adoption of the 
new SOP.

NONRECURRING CHARGES
During the third quarter of 1996, the Company recorded nonrecurring charges 
of $26.2 million related to the acquisitions of CyCare Systems, Inc. (CyCare) 
and Management Software, Inc. (MSI).  The charges consisted of transaction 
costs of $5.2 million, a write-down of long-lived assets of $7.4 million, 
severance and employee-related costs of $3.7 million and other 
product-related costs of $9.9 million.  During the fourth quarter of 1996, 
the Company recorded nonrecurring charges of $35.2 million primarily related 
to the acquisition of GMIS Inc. (GMIS).  These charges consisted of 
transaction costs of $6.2 million, a write-down of long-lived assets of $22.6 
million, severance and employee-related costs of $3.4 million and other 
product-related costs of $3.0 million.

During the second quarter of 1995, the Company recorded $126 million of 
nonrecurring charges including $115 million of purchased research and 
development related to the acquisition of First Data Health Systems 
Corporation (now known as CPG), $8 million of severance and other 
acquisition-related costs and a $3 million mainframe capitalized research and 
development net book value adjustment.  During the third quarter of 1995, the 
Company recorded a nonrecurring charge of $11 million related to the 
acquisition of CliniCom Incorporated, primarily consisting of severance and 
acquisition costs.

OTHER INCOME, NET
Other income, net, consists primarily of interest income on cash, cash 
equivalents, investments, notes receivable and financed customer receivables; 
interest expense on long-term debt, short-term line of credit borrowings and 
the sale of customer receivables; and miscellaneous expense related primarily 
to foreign exchange transaction gains and losses.

EARNINGS PER SHARE
Earnings per share is based upon the weighted average number of shares and 
the dilutive effect of stock options outstanding.  Loss per share is based 
only upon the weighted average number of shares outstanding, since the effect 
of stock options is anti-dilutive.

                                     -16-

<PAGE>

CASH AND CASH EQUIVALENTS
The Company considers all highly liquid investments purchased with an 
original maturity of three months or less from the date of purchase to be 
cash equivalents.

INVESTMENTS
Investments at December 31, 1996, and 1995 consist of debt securities and 
marketable equity securities.  Pursuant to the provisions of Statement of 
Financial Accounting Standards No. 115, "Accounting for Certain Investments 
in Debt and Equity Securities," the Company has classified its investment 
portfolio as available-for-sale.  Such securities are recorded at fair value, 
and unrealized gains and losses, net of the related tax effect, are recorded 
as a component of retained earnings until realized.  Realized gains and 
losses are determined on the specific identification method and are reflected 
in the income statement.

INVENTORIES
Inventories are valued at lower of cost or market.  Cost is determined either 
by the specific identification or first-in, first-out valuation methods.

INTANGIBLES
Intangibles consist of certain items related to the Company's acquisitions as 
follows:

</TABLE>

The Series and CPG customer lists are being amortized over 15 years beginning 
in June 1994 and June 1995, respectively.  Goodwill relates to 10 
acquisitions and is being amortized over periods ranging from five to 15 
years from the various acquisition dates.

CAPITALIZED SOFTWARE
The Company capitalizes costs to develop software products once the project 
has reached the point of technological feasibility.  Management monitors the 
net realizable value of all software development investments to ensure that 
the investment will be recovered through future sales.  Completed projects 
are amortized after reaching the point of general availability using the 
straight-line method based on an estimated useful life of three years.

HBOC capitalized software development costs of $26.0 million, $24.7 million 
and $19.4 million in 1996, 1995 and 1994, respectively.  Acquisitions 
completed in 1996 increased capitalized software $8.8 million in 1996, $10.1 
million in 1995 and $9.0 million in 1994.  The Company's nonrecurring charges 
include capitalized software net realizable value adjustments of $13.8 
million in 1996 and $4.7 million in 1995.  Amortization of capitalized 
software costs totaled $13.2 million, $15.9 million and $12.3 million in 
1996, 1995 and 1994, respectively.  

Royalty fees of $21.5 million, $13.5 million and $9.1 million were expensed 
in 1996, 1995 and 1994, respectively for third-party business partners and 
customers that assisted in the Company's development efforts.

PROPERTY AND EQUIPMENT
Property and equipment is stated at cost.  Computer equipment is depreciated 
over useful lives of two to five years using the straight-line method.  
Office furniture and equipment is depreciated over useful lives of two to 10 
years using the straight-line method.  Real property is depreciated using the 
straight-line method over various lives of up to 39 years.  Leasehold 
improvements are amortized on a straight-line basis over the shorter of the 
useful life or remaining lease term.

OTHER NONCURRENT ASSETS
Other noncurrent assets consist primarily of the long-term portion of notes 
receivable, the long-term balance in a compensation trust and accumulated 
amounts for long-term capital projects.

FAIR VALUE OF FINANCIAL INSTRUMENTS
The fair value of financial instruments classified as current assets or 
liabilities, including cash and cash equivalents, receivables and accounts 
payable, approximate carrying value due to the short-term maturity of the 
instruments.  The fair value of short-term and long-term debt approximate 
carrying value based on their effective interest rates compared to current 
market rates.

LONG-LIVED ASSETS
The Company periodically reviews the values assigned to long-lived assets, 
such as intangibles, capitalized software, and property and equipment, to 
determine if any impairments are other than temporary.  Management believes 
long-lived assets in the accompanying balance sheets are appropriately valued.

2.  INDEBTEDNESS AND COMMITMENTS:

The Company entered into a long-term revolving credit agreement in June 1994. 
The amount available under this agreement was increased to $30 million in 
1996.  As of December 31, 1996, there was no outstanding balance.  Interest 
is payable at the Company's option of prime or LIBOR plus a margin determined 
by certain of the Company's financial ratios (6.3125% as of December 31, 
1996).  A variable commitment fee on the revolving credit agreement is 
payable quarterly on the unused portion of the commitment (0.1875% for 1996). 
The agreement, which expires June 30, 1997, contains certain financial 
covenants.  The Company was in compliance with these covenants at December 
31, 1996.

During 1996, the Company canceled its $5 million committed, unsecured line of 
credit.  The Company still has a $5 million uncommitted, unsecured line of 
credit available.  No facility fees or compensating balances are associated 
with this line.

The Company has extended until June 30, 1997, its agreement with a financial 
institution whereby the Company can sell on an ongoing basis, with partial 
recourse, an undivided interest in a pool of customer receivables.  As of 
December 31, 1996, the amount available to be sold was $30 million and the 
amount sold was $10 million.  Interest is payable at the Company's option of 
prime or LIBOR plus a margin determined by certain of the Company's financial 
ratios (6.3125% as of December 31, 1996).  The Company, as agent for the 
purchaser, retains collection and administrative responsibilities for the 
receivables sold.

The Company occupies leased facilities and leases customer and other 
equipment under noncancelable leases that expire through 2011.  Most of the 
leases contain certain options to renew.  The future minimum lease 
commitments under the terms of the Company's noncancelable leases with terms 
in excess of one year, as of December 31, 1996, were as follows:

3.  CAPITAL STOCK:

In May 1996, the Company declared a two-for-one stock split of all common 
stock outstanding and in the treasury, effected in the form of a stock 
dividend that was paid on June 10, 1996, to all stockholders of record on May 
27, 1996.  All per share and share amounts (except for stockholders' equity) 
have been restated for this stock split.  In addition, stockholders approved 
an increase in the number of shares of authorized common stock from 60 
million to 250 million, effective May 15, 1996.

On February 12, 1991, the Company designated 20,000 shares of its 1,000,000 
shares of authorized preferred stock with no par value as Series A Junior 
Participating Preferred Stock with no par value and declared a dividend 
distribution of one Preferred Share Purchase Right on each outstanding share 
of the Company's common stock.  Due to the 1994 and 1996 stock splits, each 
such outstanding share is entitled to one-fourth of a Right.  Each Right, 
when exercisable, entitles its holder to buy one-thousandth of a share of the 
newly authorized preferred stock at an exercise price of $35, subject to 
adjustment.  The Rights initially will trade together with the Company's 
common stock and will not be exercisable unless certain triggering events 
occur.  Until exercisable, the Rights will not have a dilutive effect on 
earnings per share.  Following certain events, including the acquisition of 
15% of the Company's common stock, the Board of Directors may elect to 
exchange each outstanding whole Right for four shares of the Company's common 
stock, subject to adjustment.  In certain other circumstances, including the 
acquisition of 20% or more of the Company's common stock, the Rights may 
become exercisable for common stock of the Company having a market value of 
two times the Right's exercise price.  The Company will be entitled to redeem 
the Rights at one cent per Right at any time prior to the time the Rights 
become exercisable.  If the Company is acquired in a merger or other business 
combination transaction and the Rights have not been redeemed, each Right 
will entitle its holder to purchase, at the Right's then current exercise 
price, a number of the acquiring company's common shares having a market 
value at the time of two times the Right's exercise price.  The Rights will 
expire on February 22, 2001.

4.  EMPLOYEE BENEFIT PLANS:

STOCK PURCHASE PLAN
The Company has an employee discount stock purchase plan for all eligible 
employees of HBO & Company and designated subsidiaries.  Participants may use 
up to 10% of their compensation to purchase through payroll deductions the 
Company's common stock at the end of each plan year for 85% of the lower of 
the beginning or ending stock price in the plan year.  The weighted average 
fair value of shares sold under the plan in 1996 was $16.42.  At December 31, 
1996, there were 1,235,056 shares of stock reserved for issuance under this 
plan.

                                     -18-

STOCK OPTION PLANS
The Company has nonqualified and incentive stock option plans to provide key 
employees and directors with an increased incentive to work for the success 
of the Company.  The option price for all stock options is the market value 
at the date of grant and thus, the plans are non-compensatory.  The options 
expire 10 years after the dates of their respective grants.

The Company accounts for the stock purchase and stock option plans under APB 
Opinion No. 25, which requires compensation costs to be recognized only when 
the option price differs from the market price at the grant date.  FASB 
Statement No. 123 allows a company to follow APB Opinion No. 25 with the 
following additional disclosure that shows what the Company's net income 
(loss) and earnings (loss) per share would have been using the compensation 
model under FASB Statement No. 123:

Because the Statement 123 method of accounting has not been applied to 
options granted prior to January 1, 1995, the resulting pro forma 
compensation cost may not be representative of that to be expected in future 
years.

The fair value of each option grant is estimated on the date of grant using 
the Black-Scholes option pricing model with the following weighted-average 
assumptions used for grants in 1996 and 1995, respectively: risk-free 
interest rate of 6.25% and 6.65%; expected dividend yield of 0.18% and 0.36%; 
expected term of 8.8 years and 7.3 years; expected forfeiture of 4.5% and 
7.8%; and volatility of 36% for both years.

A summary of the status of the Company's stock options plans at December 31, 
1996, 1995 and 1994 and changes during the years then ended is presented in

NOTE: MSI qualified as an S Corporation prior to acquisition, and the tax 
impact was borne by the former stockholders of MSI.  Due to the taxable 
nature of the acquisition, deferred tax assets of $16.7 million were recorded 
reflecting the excess of acquired tax basis over book basis.

8.  ACQUISITIONS:

On August 21, 1996, the Company completed the acquisition of CyCare Systems, 
Inc. (CyCare), a provider of physician practice management software systems 
and electronic data interchange services for medical group practices, faculty 
practice plans and medical enterprises.  CyCare stockholders received 0.86 of 
a share of HBOC Common Stock for each share of outstanding CyCare Common 
Stock, or an aggregate of approximately 4.4 million shares.  Because the 
acquisition was accounted for as a pooling of interests, all prior period 
amounts have been restated.  

On September 19, 1996, the Company completed the acquisition of Management 
Software, Inc. (MSI), a privately held provider of software solutions for the 
homecare industry.  MSI stockholders received approximately 895,000 shares of 
HBOC Common Stock in the transaction.  Because the acquisition was accounted 
for as a pooling of interests, all prior period amounts have been restated.

On December 9, 1996, the Company completed the acquisition of GMIS Inc. 
(GMIS), a developer of data quality and decision support software for the 
payer marketplace.  GMIS stockholders received 0.42 of a share of HBOC Common 
Stock for each share of GMIS Common Stock, or an aggregate of approximately 
3.7 million shares.  Because the acquisition was accounted for as a pooling 
of interests, all prior period amounts have been restated.

9.  LEGAL PROCEEDINGS:

The Company is subject to legal proceedings and claims that arise in the 
ordinary course of business.  In the opinion of management, the amount of 
potential liability with respect to these actions will not materially affect 
the Company's financial position or results of operations.

10.  SUBSEQUENT EVENT: (UNAUDITED)

On February 11, 1997, the Company announced it had signed a definitive 
agreement to acquire AMISYS Managed Care Systems, Inc. (AMISYS), a leading 
provider of information systems for managed care entities and other parties 
that assume financial risk for healthcare populations.  The acquisition, 
which is subject to regulatory and AMISYS stockholder approval, will be 
accounted for as a pooling of interest and is scheduled to close during the 
second quarter of 1997.  Terms of the acquisition call for AMISYS 
stockholders to receive 0.35 of a share of HBOC Common Stock for each of the 
approximately 8.8 milion shares and rights to acquire shares of AMISYS Common 
Stock.

                REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Stockholders and Board of Directors of HBO & Company:

We have audited the accompanying consolidated balance sheets of HBO & Company 
(a Delaware Corporation) and subsidiaries as of December 31, 1996 and 1995, 
and the related consolidated statements of income, stockholders' equity and 
cash flows for each of the three years in the period ended December 31, 1996. 
These financial statements are the responsibility of the Company's 
management.  Our responsibility is to express an opinion on these financial 
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation.  We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of HBO & Company and 
subsidiaries as of December 31, 1996 and 1995, and the results of their 
operations and their cash flows for each of the three years in the period 
ended December 31, 1996, in conformity with generally accepted accounting 
principles.
