                                     PART I
 
ITEM 1. BUSINESS
 
(A) GENERAL DEVELOPMENT OF BUSINESS.
 
    In July 1997, the Registrant, Rollins, Inc., completed the sale of the
Plantscaping and Lawn Care divisions of its subsidiary, Orkin Exterminating
Company, Inc. (Orkin). The gross proceeds related to the sale of Orkin's
Plantscaping and Lawn Care divisions were approximately $37 million. The gain on
the sale was $15,300,000 ($9,486,000 after tax or $0.28 per share). In October
1997, the Registrant completed the sale of its Rollins Protective Services (RPS)
business segment. The gross proceeds related to the sale of RPS were
approximately $200 million. The gain on the sale was $161,000,000 ($96,600,000
after tax or $2.84 per share). Although both of these divestitures provided an
excellent return to the Company, the most significant benefit provided is the
greater focus on the core business operations of Orkin.
 
(B) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS.
 
    As a result of the divestiture of the RPS business segment as detailed in
Item 1. (a) above, the Registrant no longer has the Rollins Protective industry
segment. Therefore, this section is no longer applicable.
 
(C) NARRATIVE DESCRIPTION OF BUSINESS.
 
    (1)(i) The Registrant is a national company with headquarters located in
Atlanta, Georgia, providing services to both residential and commercial
customers. The two primary services provided are termite and pest control.
 
    Orkin Exterminating Company, Inc., a wholly owned subsidiary (Orkin),
founded in 1901, is one of the world's largest termite and pest control
companies. It provides customized services to approximately 1.6 million
customers through a network of 422 company-owned and franchised branch locations
serving customers in the United States, the District of Columbia, the Bahamas,
Canada, Mexico, and Puerto Rico. It provides customized pest control services to
homes and businesses, including hotels, food service establishments, dairy farms
and transportation companies. Orkin's continuous regular service provides
protection against household pests, rodents and termites.
 
    (ii) The Registrant has made no announcement of, nor did any information
become public about, a new line of business or product requiring the investment
of a material amount of the Registrant's total assets.
 
    (iii) Sources and availability of raw materials present no particular
problem to the Registrant, since its businesses are primarily in service-related
industries.
 
    (iv) Other than the Orkin-Registered Trademark- trademark, which is material
to the company, governmental licenses, patents, trademarks and franchises are of
minor importance to the Registrant's service operations. Local licenses and
permits are required in order for the Registrant to conduct its termite and pest
control services in certain localities. In view of the widespread operations of
the Registrant's service operations, the failure of a few local governments to
license a facility would not have a material adverse effect on the results of
operations of the Registrant.
 
    (v) The business of the Registrant is affected by the seasonal nature of the
Registrant's termite and pest control services. The metamorphosis of termites in
the spring and summer (the occurrence of which is determined by the timing of
the change in seasons) has historically resulted in an increase in the revenue
and income of the Registrant's termite and pest control operations during such
period.
 
    (vi) Inapplicable.
 
                                       2

    (vii) The Registrant and its subsidiaries do not have a material part of
their business that is dependent upon a single customer or a few customers, the
loss of which would have a material effect on the business of the Registrant.
 
    (viii) The dollar amount of service contracts and backlog orders as of the
end of the Registrant's 1997 and 1996 calendar years was approximately
$12,457,000 and $12,727,000, respectively. Backlog services and orders are
usually provided within the month following the month of receipt, except in the
area of prepaid pest control where services are usually provided within twelve
months of receipt. (Backlog orders for 1996 have been restated to exclude
backlog of the Registrant's RPS business segment and Orkin's Plantscaping and
Lawn Care divisions which were divested in 1997).
 
    (ix) Inapplicable.
 
    (x) The Registrant believes that Orkin competes favorably with competitors
as one of the world's largest termite and pest control companies.
 
    The principal methods of competition in the Registrant's termite and pest
control business are service and guarantees, including the money-back guarantee
on termite and pest control, and the termite retreatment and damage repair
guarantee to qualified homeowners.
 
    (xi) Expenditures by the Registrant on research activities relating to the
development of new products or services are not significant. Some of the new and
improved service methods and products are researched, developed and produced by
unaffiliated universities and companies. Also a portion of these methods and
products are produced to the specifications provided by the Registrant.
 
    (xii) Other than the impact on the Registrant of the 1997 Provision for
Termite Contracts which was established to address the abnormal occurrence of
termite claims, and the related cost to more frequently reapply materials, the
capital expenditures, earnings and competitive position of the Registrant and
its subsidiaries are not materially affected by compliance with Federal, state
and local provisions which have been enacted or adopted regulating the discharge
of materials into the environment, or otherwise relating to the protection of
the environment.
 
    (xiii) The number of persons employed by the Registrant and its subsidiaries
as of the end of 1997 was 8,934.
 
(D) FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT
SALES.
 
    Inapplicable.
 
ITEM 2. PROPERTIES.
 
    The Registrant's administrative headquarters and central warehouse, both of
which are owned by the Registrant, are located at 2170 Piedmont Road, N.E.,
Atlanta, Georgia 30324. The Registrant owns or leases several hundred branch
offices and operating facilities used in its businesses. None of the branch
offices, individually considered, represents a materially important physical
property of the Registrant. The facilities are suitable and adequate to meet the
current and reasonably anticipated future needs of the Registrant.
 
ITEM 3. LEGAL PROCEEDINGS.
 
    In the normal course of business, the Company is a defendant in a number of
lawsuits which allege that plaintiffs have been damaged as a result of the
rendering of services by Company personnel and equipment. The Company is
actively contesting these actions. It is the opinion of Management that the
outcome of these actions will not have a material adverse effect on the
Company's financial position, results of operations, or liquidity.
 
                                       3

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
    Inapplicable.

         REPORT OF INDEPENDENT AUDITORS ON FINANCIAL STATEMENT SCHEDULE
 
To the Directors and the Stockholders of Rollins, Inc.:
 
    We have audited, in accordance with generally accepted auditing standards,
the financial statements included in Rollins, Inc.'s annual report to
stockholders incorporated by reference in this Form 10-K, and have issued our
report thereon dated February 16, 1998. Our audits were made for the purpose of
forming an opinion on those statements taken as a whole. The schedule listed in
Item 14 of this Form 10-K is the responsibility of the Company's management and
is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.
