Item 1. Business

General Development of Business

        We are a leading healthcare staffing company and the largest provider of per diem nurse staffing services (staffing assignments of less than 13 weeks in duration) in the United States as measured by revenues. Our per diem staffing assignments place our professionals, predominately nurses, at hospitals and other healthcare facilities to solve our clients' temporary staffing needs. We believe we are also a leading provider of specialized radiology and diagnostic imaging specialists and clinical laboratory technicians, or "allied health" professionals, as measured by revenues. We serve our clients through what we believe to be the largest temporary medical staffing network in the United States, which was comprised as of December 28, 2003 of over 140 per diem branches that provide nurse staffing on a per diem basis in 43 states. Our extensive client base includes over 7,000 healthcare facilities including leading for-profit and not-for-profit hospitals, leading teaching hospitals and regional healthcare providers. We do not receive a material portion of our revenues from Medicare or Medicaid reimbursements or similar state reimbursement programs.

        Our business has grown significantly since our founding in 1998. We call branches that we have opened since our inception "de novo" branches, as opposed to branches acquired from third parties. Approximately 75% of all existing branches as of December 28, 2003 were de novo branches.

        In the second quarter of 2003, we discontinued our physician staffing services. As such, the results of operations from these services are shown separately, as a total amount, in our consolidated statements of income for all years presented.

        In March 2003, we purchased substantially all of the assets and assumed certain of the liabilities of Saber-Salisbury Group (SSG), which operates a temporary healthcare staffing company. The transaction was consummated pursuant to the terms of an asset purchase agreement, dated March 22, 2003.

        On June 16, 2003, we completed our plan to restructure our operations by closing 29 branches. The restructuring was necessary to adjust the infrastructure we had put in place to support multiple growth initiatives and reflects the current contraction in demand for our services. As a result, in the second quarter of 2003, we recorded a pre-tax charge, of approximately $0.8 million, relating to employee severance costs, branch closing costs and lease termination costs.

        For the year ended December 28, 2003, we had revenues of $513.0 million and income from operations of $17.5 million. During this period, we earned 72% of our revenues from our per diem nurse staffing assignments, 17% from our specialized radiology and diagnostic imaging technicians and clinical laboratory technicians, or our "allied health" assignments, and 11% from our travel nurse staffing assignments.

        We believe the flexibility of our service offerings provides substantial value to our clients and professionals. We provide our clients with significant assistance in managing their profitability by giving them a high degree of control in managing their labor costs without sacrificing clinical expertise. In addition, working on a per diem basis allows our healthcare professionals substantial flexibility in balancing their careers with their lifestyle objectives.

        We were formed as a Delaware corporation in 1998. Our predecessor corporation, Southeast Staffing Partners, Inc., a Florida corporation, was founded in June 1997.

Industry Overview

        The temporary nurse staffing market has two major components: per diem nursing and travel nursing. Per diem nurse staffing is the largest sector of the temporary medical staffing industry, providing healthcare professionals for assignments of a single shift to 13 weeks, and is used to meet

1

local labor shortages and openings due to holidays, vacations, illness and staff turnover, as well as daily and seasonal fluctuations in hospital volume. The per diem market operates with many local operators and is highly fragmented. The per diem staffing model requires a local presence in every market served because these short-term staffing needs are typically filled on a local basis, and are dependant on the relationship that exists between local operators, local professionals and the healthcare facility.

        In the travel nurse market, healthcare facilities hire travel nurses on a contract, fixed-term basis to meet seasonal fluctuations in hospital census levels for time periods ranging from several weeks to one year, but are typically 13 weeks long. Travel nurse companies coordinate travel and housing arrangements for their professionals who typically relocate to the area in which they are placed. The travel staffing model utilizes a centralized approach to serving its clients.

        Allied staffing consists of highly specialized radiology and diagnostic imaging specialties, clinical laboratory specialties, pharmacists and respiratory therapists. These professionals are staffed on both a per diem and travel basis.

        Service revenues and gross profit margins have been under pressure as demand for temporary nurses is currently going through a period of contraction. Due to the current difficult economic times, the unemployment rate is near a nine-year high, which we believe has resulted in nurses in many households becoming a primary breadwinner, and which is causing such nurses to seek more traditional full-time employment. Additionally, hospitals are experiencing lower than projected census levels and are placing greater reliance on existing full-time staff, resulting in increased overtime and nurse-patient loads.

        We cannot predict when conditions will reverse, but we are confident in the long-term growth of the industry. In a January 13, 2000 report, the U.S. Census Bureau, Population Projections Bureau, projected that the number of Americans over 65 years of age is expected to grow from 34.5 million in 2000 to 53.7 million in 2020. In a July 2002 report, the U.S. Department of Health and Human Services stated that the national supply of full-time equivalent registered nurses was approximately 1.9 million while demand was approximately 2.0 million. This gap between supply and demand, for nurses, is expected to grow from 0.1 million in 2000 to 0.8 million by 2020. In conjunction with the two aforementioned factors, as the economy rebounds, the prospects for the healthcare staffing industry should improve as hospitals experience higher census levels and increasing shortages of healthcare workers.

Description of the Business

        We provide hospitals and other healthcare facilities with a wide range of staffing services, including per diem nurses, allied professionals and travel nurses. While we have a national presence, we operate on a local basis through an integrated network, which consisted of over 140 per diem branches in 43 states as of December 28, 2003, so that we may develop significant relationships with our clients and healthcare professionals and provide the highest level of service. We have provided services to over 7,000 healthcare facilities that have paid us directly for the services we provide.

Services Provided

        Per Diem Nursing.    The per diem nurse staffing portion of our business provides nurses for assignments with durations ranging from a single shift to a 13-week assignment and represented approximately 72% of our fiscal year 2003 revenues. We offer our clients all major classifications of nurses, including registered nurses and licensed practical nurses, across all specialties such as pediatric, geriatric, intensive care unit and cardiovascular. We provide per diem personnel to a variety of healthcare facilities including acute care hospitals, nursing homes, clinics and surgical and ambulatory care centers. We serve both for-profit and not-for-profit organizations that range in scope from one facility to national chains with over 100 facilities.

2

        Allied Staffing.    Our allied staffing division, which represented approximately 17% of our 2003 revenues, specializes in providing allied professionals to hospitals, nursing homes, clinics and surgical and ambulatory care centers, both on a per diem and a travel basis. We believe our allied healthcare business to be among the largest in the country as measured by revenues. Allied specialties that we staff include diagnostic imaging and radiology technicians, clinical laboratory technicians, pharmacists and respiratory therapists.

        Travel Nursing.    Comprising approximately 11% of our 2003 revenues, our travel nursing operations provide nurses and surgical technicians to hospitals across the country for assignments lasting over thirteen weeks.

        Physicians.    During the second quarter of 2003, we discontinued our physician staffing operation, and as such, the results of operations from these services are shown separately, as a total amount, in our consolidated statements of income for all years presented.

National Branch Network

        We currently operate an integrated network, which consisted of over 140 per diem branches located in 43 states as of December 28, 2003. Our branches are organized into several geographic regions, each of which is coordinated by a regional director. These branches serve as our direct contact with our healthcare professionals and clients and are active in recruiting, scheduling and sales and marketing. Each branch is responsible for covering a specific local geographic region. Our typical branch is staffed with four or five professionals who are responsible for the day-to-day operations of the business. These professionals include a branch manager, two to three staffing coordinators, and a payroll administrator.

        The cost structure of our typical branch is primarily fixed, consisting of limited personnel, office space rent, information systems infrastructure and supplies. We have been able to develop a highly efficient branch management model that is easily scaleable to meet increasing demand.

Recruitment and Retention

        Our ability to recruit and retain a pool of talented, motivated and highly credentialed healthcare professionals is critical to our success. Our active pool of professionals has grown 52% compounded annually from 7,000 in 1999 to 37,000 in 2003, with a significant number of new recruits generated via word of mouth. Over 80% of our senior operations management has nursing or other clinical backgrounds. We believe this depth of clinical experience helps us understand the needs of clinical personnel and has enhanced our reputation in the industry as an advocate for nurses and other healthcare professionals, improving our ability to recruit such personnel. In addition, we offer competitive benefits packages that differentiate us from the smaller, local per diem staffing companies with which we compete, and which are typically unable to offer the package of services and benefits that we offer. We believe our competitive advantages in recruiting skilled personnel include the ability to offer the following opportunities to our personnel:

•

Flexible Staffing Assignments. We provide our professionals with the flexibility to tailor their staffing schedules to accommodate lifestyle choices. There are many reasons why qualified nurses choose to work on a per diem basis, but most are motivated by the ability to balance their profession with their other responsibilities and interests. Our professionals are able to choose not only when they work but also where they work. Our scheduling systems are designed to place our professionals in facilities and shifts where they have had a productive and positive experience with our clients.



•

Competitive Benefits Package. We believe that we were the first per diem healthcare staffing company to offer a comprehensive benefits program for qualified per diem staff. Our program

3

includes a matching 401(k) plan and access to group discounted benefits such as health, dental, life, disability and general liability insurances for healthcare professionals who work for us for a specified minimum number of hours per month for more than one month.

•

Choice of Pay Frequency—Including Daily. Our ability to offer pay as frequently as daily provides our professionals with another key element of flexibility. Rather than waiting for the end of a traditional weekly or biweekly pay period, our professionals can be paid immediately after completing their shifts. This allows our branch staff to maintain an active dialogue with our professionals regarding future assignments. This consistent interaction fosters unique relationships that distinguish us from our competition.



•

Leading Continuing Educational Programs. We also offer continuing education courses as a means to improve our pool of nurses as well as to maintain proper compliance. We have a unique relationship with Florida Atlantic University's College of Nursing. The College of Nursing faculty develops continuing education courses that we offer online through our website. Our nurses can obtain continuing education units (CEUs) that many states require to educate our nurses regarding changing technology and clinical practices. Our courses are fully accredited by the American Nurses Credentialing Center of Excellence and the Florida Board of Nursing.

        We have several proven recruitment channels that consistently augment our pool of healthcare professionals at low marginal cost. In 2003, we spent approximately 1% of our revenues on recruitment activities. Our recruiting activities include print advertisements in local newspapers and in trade journals, mailings, Internet listings and solicitations at trade conventions.

Quality Management

        We have developed a substantial clinical quality improvement program to uphold our high standards in recruiting healthcare professionals. Our two-step internal process ensures that all of our temporary professionals have the proper credentials, skills and experience for their assignments. We have found that our adherence to high quality management standards is an integral component of satisfying both clients and professionals with our placements. Our two-step process for quality management includes the following:

        Pre-employment Qualifications.    All of our per diem healthcare professionals undergo a rigorous screening process which includes requirements such as a minimum of one year of related work experience and the successful completion of written tests specific to the area of specialty. Each applicant is then interviewed in person by a local branch manager. This sets us apart from our competitors who often do not conduct face-to-face interviews. We also check prior work references, confirm the validity of the applicant's professional license(s) and screen the applicant for any criminal activity and drug abuse. All of these standards comply with or exceed those required by OSHA (Occupational Safety & Health Administration) and JCAHO (Joint Commission on Accreditation of Healthcare Organizations).

        Placement and Ongoing Monitoring.    Once we have hired a healthcare professional, we enter all of the professional's data into our database, which tracks any "renewal dates" with respect to licenses and continuing education requirements. Our database also matches our clients' needs with our available pool of professionals. We strive to place our professionals in facilities where they have previously worked in order to enhance the continuity of our services to our clients. If this is not possible, we provide our professionals with pre-staffing orientation to the facility. By taking these steps, we ensure that the healthcare professional is comfortable with the facility's physical layout, permanent staff and clinical protocols. We also continually monitor the performance of our professionals through evaluations and client feedback, among other things. In addition, our database allows remote access (via the Internet) by our clients, providing them the ability to view the credentials of the professionals being staffed at their facilities.

4

Sales and Marketing

        We have developed a three-pronged approach to our sales and marketing activities in order to address the different levels of decision makers at our clients' facilities:

        Our first level of business development and relationship management is with the purchasing manager, administrator(s) or chief nursing officer at a group of facilities we service. Commonly-owned hospitals, nursing home chains and healthcare group alliances often purchase temporary staffing services for multiple facilities under a single contract, and a single person typically manages the selection process. A senior member of our staff, the regional director and, in certain circumstances, the Executive Vice President of Nurse Per Diem Operations, handle the negotiation of contractual terms and pricing with such groups of facilities.

        Our second level of business development and relationship management is with the director of nursing or a nurse/allied department manager who reviews our services from a clinical competency and quality hiring standards perspective. Our regional director and local branch manager establish, build and maintain relationships at this level.

        Our third level of relationship management is with the facility staffing coordinators and the after-hours and weekend supervisors who are the actual users of the services. Our branch managers and local staffing coordinators regularly contact these buyers to coordinate the daily staffing and scheduling of personnel.

Information Systems

        Our information system for our per diem staffing operation, for which we hold an exclusive twenty-five year license and which we refer to as MSN HealthWorks, is customized to our recruiting, regulatory credentialing, scheduling and billing needs. Not only is the database used as a management tool, but it is also used by our staffing coordinators in each branch to respond quickly to client questions and requests. MSN HealthWorks' applications and its supporting infrastructure house and organize all of our client and employee information. Electronic files are maintained on our client facilities, detailing historical and prospective requests for staffing. These files also contain facility-specific procedures and protocols so that we can ensure our healthcare professionals integrate quickly. Each employee's electronic file contains the employee's credentials, test scores, employment record and availability. This data enables our branch-office staff to automatically match open requests with qualified candidates.

        MSN HealthWorks also monitors billing records using time cards to generate invoices for our clients and paycheck information for our employees. MSN HealthWorks operates as a single entry system, meaning that the initial shift confirmation entry enables our payroll to be generated at the branch level on a daily basis and the invoicing to be generated at our corporate office. This system enables us not only to monitor costs and compliance, but also to ensure that we respond to client requests as quickly as possible. We typically fill a client staffing request in less than 15 minutes.

        We have adapted our MSN HealthWorks platform to provide our clients with functionality for budgeting and access to nurse and employee credentials via an Internet connection.

Competition

        The temporary medical staffing industry is highly competitive. We compete with both national firms and local and regional firms. We compete with these firms to attract nurses and other healthcare professionals as temporary healthcare professionals and to attract hospital and healthcare facility clients. We compete for temporary healthcare professionals on the basis of the quantity, diversity and quality of assignments available, compensation packages, and the benefits that we provide to temporary healthcare professionals while they are on assignment. We compete for hospital and healthcare facility clients on the basis of the quality of our temporary healthcare professionals, the timely availability of our professionals with the requisite skills, quality and scope, price and geographic reach of our services.

5

        The per diem market includes many local operators and is highly fragmented. The per diem staffing business requires a local presence in every market served since an important relationship exists between the local branch and the healthcare facility. We believe, however, that larger, nationally established firms enjoy distinct competitive advantages over smaller, local and regional competitors in the healthcare staffing industry. Larger and more established firms have a critical mass of available nursing candidates, substantial word-of-mouth referral networks and established brand names, enabling them to attract a consistent flow of new applicants. Larger firms can also more easily provide payroll services, which are cash flow intensive, to healthcare providers. As a result, sizable and established firms such as ours have had a significant advantage over small participants.

        Some of our large competitors in the temporary medical staffing industry include AMN Healthcare Services, Inc., Cross Country Healthcare, Inc. and InteliStaf Healthcare, Inc.

Liability Insurance

        We currently maintain a professional liability insurance policy, which we believe is sufficient for the risks associated with our business. Medical malpractice claims against us relating to our healthcare professionals are defended by our insurance carrier. We have indemnity agreements with approximately 80% of our clients which state that we will defend, indemnify and hold harmless those clients against any act of omission or willful or reckless acts, including negligence and misconduct. A majority of such agreements are reciprocal.

Trademarks and Service Marks

        The service mark "Medical Staffing Network, Inc." (Name and Logo), which was registered with the U.S. Patent and Trademark Office as of May 6, 2003, and the trade name "Medical Staffing Network" are each owned and licensed from Medical Staffing Network Assets, LLC, our indirectly wholly-owned subsidiary.

Government Regulation

        The healthcare industry is subject to extensive and complex federal and state laws and regulations relating to professional licensure, conduct of operations, payment for services and payment for referrals. The extensive and complex laws that apply to our hospital and healthcare facility clients, including laws related to Medicare, Medicaid and other federal and state healthcare programs, could indirectly affect the demand or the prices paid for our services. For example, our hospital and healthcare facility clients could suffer civil and/or criminal penalties and/or be excluded from participating in Medicare, Medicaid and other healthcare programs if they fail to comply with the laws and regulations applicable to their businesses.

        Our business, however, is not directly impacted by or subject to the laws and regulations that generally govern the healthcare industry, because we provide services on a contract basis and are paid directly by our hospital and other healthcare facility clients.

        Some states require state licensure for businesses that employ and/or assign healthcare personnel to provide healthcare services on-site at hospitals and other healthcare facilities. We hold a Nursing Pool License in those jurisdictions in which we do business that require such licenses, which are Connecticut, Delaware, the District of Columbia, Florida, Illinois, Iowa, Kentucky, Maine, Maryland, Massachusetts, Minnesota, New Jersey, Nevada, North Carolina, Rhode Island, Tennessee, Texas and Washington.

        Most of our temporary healthcare professionals are required to be individually licensed or certified under applicable state laws. We take reasonable steps to ensure that our professionals possess all necessary licenses and certifications in all material respects. These steps include: employee must present

6

original version of state issued license; we validate employee's identity through government issued photo identification; we call or verify online employee's license with the applicable state board prior to assignment; and, a copy of the license is maintained in the employee's personnel file and expiration dates are monitored through our MSN HealthWorks platform.

Seasonality

        Due to the regional and seasonal fluctuations in the hospital patient census of our hospital and healthcare facility clients and due to the seasonal preferences for destinations by our temporary healthcare professionals, the number of healthcare professionals on assignment, revenue and earnings are subject to moderate seasonal fluctuations. Many of our hospital and healthcare facility clients are located in areas, particularly Florida, that experience seasonal fluctuations in population, during the winter and summer months. These facilities adjust their staffing levels to accommodate the change in this seasonal demand and many of these facilities utilize temporary healthcare professionals to satisfy these seasonal staffing needs.

        Historically, the number of temporary healthcare professionals on assignment has increased from December through March followed by declines or minimal growth from April through November. This pattern may or may not continue in the future. As a result of all of these factors, results of any one quarter are not necessarily indicative of the results to be expected for any other quarter or for any year.

Employees

        As of December 28, 2003, we employed 1,338 people in the following areas: 1,170 in branch staff, 148 in corporate office staff and 20 in regional and de novo operations staff. In addition, during 2003 we employed over 37,000 temporary healthcare professionals. We do not have any organized labor unions. We believe we have excellent relationships with our employees.

        Generally, our allied health professionals, per diem nurses and travel nurses are our employees. However, our certified registered nurse anesthetists and anesthesiologists are, and before discontinuation of our physician staffing business our physicians were, independent contractors. We have not entered into any employment agreements with any of our healthcare professionals.

Available Information

        We file annual, quarterly and current reports and other information with the Securities and Exchange Commission. Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, are available free of charge in the "Investor Relations" section of our website at www.msnhealth.com. These reports, and any amendments to these reports, are made available on our website as soon as reasonably practicable after such reports are filed with or furnished to the Securities and Exchange Commission.

Risk Factors

        There are a number of factors, including those specified below, which may adversely affect our business, financial results or stock price. Additional risks that we do not know about or that we currently view as immaterial may also impair our business or adversely impact our financial results or stock price.

Risks Related to Our Business and Industry

        If we are unable to attract qualified nurses and allied healthcare professionals for our healthcare staffing business, our business could be negatively impacted.

        We rely significantly on our ability to attract and retain nurses and allied healthcare professionals who possess the skills, experience and licenses necessary to meet the requirements of our hospital and healthcare facility clients. We compete for healthcare staffing personnel with other temporary healthcare staffing companies and with hospitals and healthcare facilities. We must continually evaluate and expand our temporary healthcare professional network to keep pace with our hospital and healthcare facility clients' needs. Currently, there is a shortage of qualified nurses in most areas of the United States, competition for nursing personnel is increasing, and salaries and benefits have risen. We may be unable to continue to increase the number of temporary healthcare professionals that we recruit, decreasing the potential for growth of our business. Our ability to attract and retain temporary healthcare professionals depends on several factors, including our ability to provide temporary healthcare professionals with assignments that they view as attractive and to provide them with competitive benefits and wages. We cannot assure you that we will be successful in any of these areas. The cost of attracting temporary healthcare professionals and providing them with attractive benefits packages may be higher than we anticipate and, as a result, if we are unable to pass these costs on to our hospital and healthcare facility clients, our profitability could decline. Moreover, if we are unable to attract and retain temporary healthcare professionals, the quality of our services to our hospital and healthcare facility clients may decline and, as a result, we could lose clients.

        Contraction of demand for our temporary nurses may continue if unemployment rates remain high or increase and hospital census levels remain lower than projected.

        Demand for temporary nurses is currently experiencing a period of contraction. Due to the current difficult economic times, the unemployment rate is near a nine-year high, which we believe has resulted in nurses in many households becoming a primary breadwinner, and which is causing such nurses to seek more traditional full-time employment. Additionally, hospitals are experiencing lower than projected census levels and are placing greater reliance on existing full-time staff, resulting in increased overtime and nurse-patient loads. Consequently, our service revenues and gross profit margins have been under pressure. In June 2003, we completed a plan to restructure our operations by closing 29 branches. The restructuring was in response to the current contraction in demand for our services and was necessary to adjust the infrastructure we had put in place to support multiple growth initiatives. If these industry trends continue, our revenues and gross profit margins may decline.

        We operate in a highly competitive market and our success depends on our ability to remain competitive in obtaining and retaining hospital and healthcare facility clients and temporary healthcare professionals.

        The temporary medical staffing business is highly competitive. We compete in national, regional and local markets with full-service staffing companies and with specialized temporary staffing agencies. Some of our competitors in the temporary nurse staffing sector include AMN Healthcare Services, Inc., Cross Country Healthcare, Inc. and InteliStaf Healthcare, Inc. Some of these companies may have greater marketing and financial resources than we do. Competition for hospital and healthcare facility clients and temporary healthcare professionals may increase in the future and, as a result, we may not be able to remain competitive. To the extent competitors seek to gain or retain market share by reducing prices or increasing marketing expenditures, we could lose revenues or hospital and healthcare

8

facility clients and our margins could decline, which could seriously harm our operating results and cause the price of our stock to decline. In addition, the development of alternative recruitment channels could lead our hospital and healthcare facility clients to bypass our services, which would also cause our revenues and margins to decline.

        Our business depends upon our continued ability to secure and fill new orders from our hospital and healthcare facility clients, because we do not have long-term agreements or exclusive contracts with them.

        We do not have long-term agreements or exclusive guaranteed order contracts with our hospital and healthcare facility clients. The success of our business depends upon our ability to continually secure new orders from hospitals and other healthcare facilities and to fill those orders with our temporary healthcare professionals. Our hospital and healthcare facility clients are free to place orders with our competitors and may choose to use temporary healthcare professionals that our competitors offer them. Therefore, we must maintain positive relationships with our hospital and healthcare facility clients. If we fail to maintain positive relationships with our hospital and healthcare facility clients, we may be unable to generate new temporary healthcare professional orders and our business may be adversely affected.

        Reacting to concerns over agency utilization in prior years, hospitals and other healthcare facilities have devised strategies to reduce agency expenditure and limit overall agency utilization. If current pressures to control agency usage continue and escalate, we will have fewer business opportunities, which could harm our business.

        An important part of our long-term strategy is the expansion of market share of our business through the opening and development of de novo branches and the expansion of the service areas of our existing branches. The success of this expansion depends on our ability to continue to identify and retain local management and to secure good locations.

        Since our founding in 1998, we have opened many de novo branches. This expansion activity contributed substantially to our operating results and has been an important part of our business strategy. Our ability to open de novo branches depends on a number of factors, including identifying, attracting and retaining local management and securing good locations on acceptable terms. In 2003, we opened five de novo branches as compared to 40 for 2002. If our ability to open de novo branches or the ability to expand the service areas of our existing branches is impaired, our revenue growth may be adversely affected. In addition, if our existing de novo branches do not develop as quickly as we anticipate, or if we fail to integrate de novo branches effectively into our national network, our results of operations and cash flows may be adversely affected.

        Fluctuations in patient occupancy at our hospital and healthcare facility clients may adversely affect the demand for our services and therefore the profitability of our business.

        Demand for our temporary healthcare staffing services is significantly affected by the general level of patient occupancy at our hospital and healthcare facility clients. When occupancy increases, hospitals and other healthcare facilities often add temporary employees before full-time employees are hired. As occupancy decreases, hospitals and other healthcare facilities typically reduce their use of temporary employees before undertaking layoffs of their regular employees. In addition, we may experience more competitive pricing pressure during periods of occupancy downturn. Occupancy at our hospital and healthcare facility clients also fluctuates due to the seasonality of some elective procedures. We are unable to predict the level of patient occupancy at any particular time and its effect on our revenues and earnings.

        Healthcare reform could negatively impact our business opportunities, revenues and margins.

        The U.S. government has undertaken efforts to control increasing healthcare costs through legislation, regulation and voluntary agreements with medical care providers and drug companies. In

9

the recent past, the U.S. Congress has considered several comprehensive healthcare reform proposals. The proposals were generally intended to expand healthcare coverage for the uninsured and reduce the growth of total healthcare expenditures. While the U.S. Congress did not adopt any comprehensive reform proposals, members of Congress may raise similar proposals in the future. If any of these proposals are approved, hospitals and other healthcare facilities may react by spending less on healthcare staffing, including nurses. If this were to occur, we would have fewer business opportunities, which could seriously harm our business.

        State governments have also attempted to control increasing healthcare costs. For example, the state of Massachusetts has implemented a regulation that limits the hourly rate payable to temporary nursing agencies for registered nurses, licensed practical nurses and certified nurses' aides. The state of Minnesota has also implemented a statute that limits the amount that nursing agencies may charge nursing homes. Other states have also proposed legislation that would limit the amounts that temporary staffing companies may charge. Any such current or proposed laws could seriously harm our business, revenues and margins.

        Furthermore, third party payors, such as health maintenance organizations, increasingly challenge the prices charged for medical care. Failure by hospitals and other healthcare facilities to obtain full reimbursement from those third party payors could reduce the demand or the price paid for our staffing services.

        There is a growing trend to restrict mandatory healthcare worker overtime requirements by employers and to establish nurse-patient ratios. The state of California has already enacted such legislation and several other states have similar legislation pending. This legislation could ultimately have a potential positive or negative impact on our business.

        We operate in a regulated industry and changes in regulations or violations of regulations may result in increased costs or sanctions that could reduce our revenues and profitability.

        The healthcare industry is subject to extensive and complex federal and state laws and regulations related to professional licensure, conduct of operations, payment for services and payment for referrals. If we fail to comply with the laws and regulations that are directly applicable to our business, we could suffer civil and/or criminal penalties or be subject to injunctions or cease and desist orders.

        The extensive and complex laws that apply to our hospital and healthcare facility clients, including laws related to Medicare, Medicaid and other federal and state healthcare programs, could indirectly affect the demand or the prices paid for our services. For example, our hospital and healthcare facility clients could suffer civil and/or criminal penalties and/or be excluded from participating in Medicare, Medicaid and other healthcare programs if they fail to comply with the laws and regulations applicable to their businesses. In addition, our hospital and healthcare facility clients could receive reduced reimbursements, or be excluded from coverage, because of a change in the rates or conditions set by federal or state governments. In turn, violations of or changes to these laws and regulations that adversely affect our hospital and healthcare facility clients could also adversely affect the prices that these clients are willing or able to pay for our services.

We are dependent on the proper functioning of our information systems.

        Our company is dependent on the proper functioning of our information systems in operating our business. Critical information systems used in daily operations identify and match staffing resources and client assignments and regulatory credentialing scheduling and perform billing and accounts receivable functions. Our information systems are vulnerable to fire, storm, flood, power loss, telecommunications failures, physical or software break-ins and similar events. If our information systems fail or are otherwise unavailable, these functions would have to be accomplished manually, which could impact

10

our ability to identify business opportunities quickly, maintain billing and clinical records reliably, pay our staff in a timely fashion and bill for services efficiently.

        Competition for acquisition opportunities may restrict our future growth by limiting our ability to make acquisitions at reasonable valuations.

        Since our founding in 1998, we have completed 26 acquisitions. Our business strategy includes increasing our market share and presence in the temporary healthcare staffing industry through strategic acquisitions of companies that complement or enhance our business. We have historically faced competition for acquisitions. In the future, this could limit our ability to grow by acquisitions or could raise the prices of acquisitions and make them less accretive to us. In addition, restrictive covenants in our credit facility, including a covenant that requires us to obtain the approval of our lenders for any acquisition with a purchase price over $3 million, may limit our ability to complete desirable acquisitions. If we are unable to secure necessary financing under our credit facility or otherwise, we may be unable to complete desirable acquisitions.

        We may face difficulties integrating our acquisitions into our operations and our acquisitions may be unsuccessful, involve significant cash expenditures or expose us to unforeseen liabilities.

        We continually evaluate opportunities to acquire healthcare staffing companies that complement or enhance our business and frequently have preliminary acquisition discussions with some of these companies.

        These acquisitions involve numerous risks, including:

•

potential loss of key employees or clients of acquired companies;



•

difficulties integrating acquired personnel and distinct cultures into our business;



•

difficulties integrating acquired companies into our operating, financial planning and financial reporting systems;



•

diversion of management attention from existing operations; and



•

assumption of liabilities and exposure to unforeseen liabilities of acquired companies, including liabilities for their failure to comply with healthcare regulations.

        These acquisitions may also involve significant cash expenditures, debt incurrence and integration expenses that could seriously harm our financial condition and results of operations. Any acquisition may ultimately have a negative impact on our business and financial condition.

Our ability to borrow under our new credit facility may be limited.

        On December 22, 2003, we entered into a new credit facility, consisting of a three-year $65 million asset-based revolving credit facility and a two-year $17 million term note. Our ability to borrow under the new credit facility is based upon, and thereby limited by, the amount of our accounts receivable. Any material deterioration in our service revenues could reduce our borrowing base, which could cause us to lose our ability to borrow additional amounts under the new credit facility. In such a circumstance, the borrowing availability under the new credit facility may not be sufficient for our capital needs.

11

        Significant legal actions could subject us to substantial uninsured liabilities.

        In recent years, healthcare providers have become subject to an increasing number of legal actions alleging malpractice, product liability or related legal theories. Many of these actions involve large claims and significant defense costs. In addition, we may be subject to claims related to torts or crimes committed by our employees or temporary healthcare professionals. In some instances, we are required to indemnify our clients against some or all of these risks. A failure of any of our employees or healthcare professionals to observe our policies and guidelines intended to reduce these risks, relevant client policies and guidelines or applicable federal, state or local laws, rules and regulations could result in negative publicity, payment of fines or other damages. Our professional malpractice liability insurance and general liability insurance coverage may not cover all claims against us or continue to be available to us at a reasonable cost. If we are unable to maintain adequate insurance coverage or if our insurers deny coverage we may be exposed to substantial liabilities.

        We may be legally liable for damages resulting from our hospital and healthcare facility clients' mistreatment of our healthcare personnel.

        Because we are in the business of placing our temporary healthcare professionals in the workplaces of other companies, we are subject to possible claims by our temporary healthcare professionals alleging discrimination, sexual harassment, negligence and other similar activities by our hospital and healthcare facility clients. The cost of defending such claims, even if groundless, could be substantial and the associated negative publicity could adversely affect our ability to attract and retain qualified healthcare professionals in the future.

        If we become subject to material liabilities under our self-insured programs, our financial results may be adversely affected.

        We provide workers compensation coverage through a program that is partially self-insured. In addition, we provide medical coverage to our employees through a partially self-insured preferred provider organization. If we become subject to substantial uninsured workers compensation or medical coverage liabilities, our financial results may be adversely affected.

        Our operations may deteriorate if we are unable to continue to attract, develop and retain our sales personnel.

        Our success depends upon the performance of our sales personnel, especially regional directors, branch managers and staffing coordinators. The number of individuals who meet our qualifications for these positions is limited and we may experience difficulty in attracting qualified candidates. In addition, we commit substantial resources to the training, development and support of these individuals. Competition for qualified sales personnel in the line of business in which we operate is strong and there is a risk that we may not be able to retain our sales personnel after we have expended the time and expense to recruit and train them.

        The loss of key senior management personnel could adversely affect our ability to remain competitive.

        We believe that the success of our business strategy and our ability to operate profitably depends on the continued employment of our senior management team, consisting of Robert J. Adamson, Kevin S. Little, Greg Guckes, Patricia G. Donohoe, Lynne Stacy, Judy Johnson, Jan Casford and Pat Layton. If any members of our senior management team become unable or unwilling to continue in their present positions, our business and financial results could be materially adversely affected.

        We have a substantial amount of goodwill on our balance sheet. Our level of goodwill may have the effect of decreasing our earnings or increasing our losses.

        As of December 28, 2003, we had $125 million of goodwill, net on our balance sheet, which represents the excess of the total purchase price of our acquisitions over the fair value of the net assets acquired. At December 28, 2003, goodwill represented approximately 55% of our total assets.

        Historically, we amortized goodwill on a straight-line basis over the estimated period of future benefit of 20 years. In July 2001, the Financial Accounting Standards Board issued SFAS No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001, as well as all purchase method business combinations completed after June 30, 2001. SFAS No. 142 requires that, subsequent to January 1, 2002, goodwill not be amortized but rather that it be reviewed annually for impairment. In the event impairment is identified, a charge to earnings would be recorded. We have adopted the provisions of SFAS No. 141 and SFAS No. 142 as of December 31, 2001. Although it does not affect our cash flow, amortization of goodwill or an impairment charge to earnings has the effect of decreasing our earnings or increasing our losses, as the case may be. If we are required to amortize a substantial amount of goodwill or take a charge to earnings, our stock price could be adversely affected.

        Our costs of providing housing for nurses and other healthcare personnel in our travel business may be higher than we anticipate and, as a result, our margins could decline.

        We currently have approximately 200 apartments on lease throughout the United States. If the costs of renting apartments and furniture for our nurses and other healthcare personnel increase more than we anticipate and we are unable to pass such increases on to our clients, our margins may decline. To the extent the length of a nurse's or other professional's housing lease exceeds the term of the nurse's or other professional's staffing contract, we bear the risk that we will be obligated to pay rent for housing we do not use. To limit the costs of unutilized housing, we try to secure leases with term lengths that match the term lengths of our staffing contracts, which typically last 13 weeks. In some housing markets we have had, and believe we will continue to have, difficulty identifying short-term leases. If we cannot identify a sufficient number of appropriate short-term leases in regional markets, or if, for any reason, we are unable to efficiently utilize the apartments we do lease, we may be required to pay rent for unutilized housing or, to avoid such risk, we may forego otherwise profitable opportunities.

        Demand for medical staffing services is significantly affected by the general level of economic activity and unemployment in the United States.

        When economic activity increases, temporary employees are often added before full-time employees are hired. However, as economic activity slows, many companies, including our hospital and healthcare facility clients, reduce their use of temporary employees before laying off full-time employees. In addition, we may experience more competitive pricing pressure during periods of economic downturn. Therefore, any significant economic downturn could have a material adverse impact on our condition and results of operations.

        Our executive officers, directors and significant stockholders will be able to influence matters requiring stockholder approval and could discourage the purchase of our outstanding shares at a premium.

        Our executive officers and directors (including stockholders with which directors are affiliated) control approximately 62% of our outstanding common stock. Warburg Pincus Private Equity Fund VIII, L.P., a Delaware limited partnership (Warburg Pincus), owns approximately 46% of our common stock. This concentration of ownership may have the effect of delaying, preventing or deterring a change in control of our company, could deprive our stockholders of an opportunity to receive a

13

premium for their common stock as part of a sale or merger of our company and may negatively affect the market price of our common stock. These transactions might include proxy contests, tender offers, mergers or other purchases of common stock that could give our stockholders the opportunity to realize a premium over the then-prevailing market price for shares of our common stock.

        Warburg Pincus has the right under our stockholders agreement to designate two persons to our Board of Directors. As a result of this share ownership and minority representation on our Board of Directors, our current stockholders, in particular Warburg Pincus, will be able to influence all affairs and actions of our company, including matters requiring stockholder approval such as the election of directors and approval of significant corporate transactions. The interests of our executive officers, directors and principal stockholders may differ from the interests of the other stockholders.

        Warburg Pincus and certain significant stockholders have demand registration rights to cause us to file, at any time and at our expense, a registration statement under the Securities Act covering resales of their shares. These shares represent approximately 46% of our outstanding common stock, or approximately 14.0 million shares. These shares may also be sold under Rule 144 of the Securities Act, depending on their holding period and subject to significant restrictions in the case of shares held by persons deemed to be our affiliates.

        If provisions in our corporate documents and Delaware law delay or prevent a change in control of our company, we may be unable to consummate a transaction that our stockholders consider favorable.

        Provisions in our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition involving us that our stockholders may consider favorable. For example, our certificate of incorporation authorizes our Board of Directors to issue up to 15 million shares of "blank check" preferred stock. Without stockholder approval, the Board of Directors has the authority to attach special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third party to acquire us. Applicable Delaware law may also discourage, delay or prevent someone from acquiring or merging with us.

        Our stock price may be volatile and your investment in our common stock could suffer a decline in value.

        With the current uncertainty about healthcare policy, reimbursement and coverage in the United States, there has been significant volatility in the market price and trading volume of securities of healthcare and other companies, which is unrelated to the financial performance of these companies. These broad market fluctuations may negatively affect the market price of our common stock.

        Some specific factors that may have a significant effect on our common stock market price include:

•

actual or anticipated fluctuations in our operating results;



•

actual or anticipated changes in our growth rates or our competitors' growth rates;



•

actual or anticipated changes in healthcare policy in the United States and internationally;



•

conditions in the financial markets in general or changes in general economic conditions;



•

our inability to raise additional capital;



•

conditions of other medical staffing companies or the medical staffing industry generally; and



•

changes in stock market analyst recommendations regarding our common stock, other comparable companies or the medical staffing industry generally.

Item 2. Properties

        Our U.S. corporate headquarters is located in Boca Raton, Florida and has an aggregate of 50,000 square feet. We operate on a national basis with a presence in 43 states and over 140 locations as of December 28, 2003. The facilities at our headquarters and at each of our locations are leased. The lease to our headquarters expires in 2013. We believe that our properties are adequate for our current needs. In addition, we believe that adequate space can be obtained to meet our foreseeable business needs. With the exception of our corporate headquarters, we have no material operating leases.

Item 3. Legal Proceedings

        On February 20, 2004, Joseph and Patricia Marrari filed a class action lawsuit against Medical Staffing Network in the United States District Court of the Southern District of Florida, on behalf of themselves and purchasers of our common stock pursuant to or traceable to our initial public offering in April 2002. The lawsuit also named as defendants certain of our directors and executive officers. The complaint alleges that certain disclosures in the Registration Statement/Prospectus filed in connection with our initial public offering on April 17, 2002 were materially false and misleading in violation of Sections 11 and 15 of the Securities Act of 1933. The complaint seeks compensatory damages as well as costs and attorney fees.

        On March 3, 2004, another class action complaint was filed by Jerome Gould against Medical Staffing Network and certain of our directors and executive officers in the United States District Court for the Southern District of Florida, individually and on behalf of a class of Medical Staffing Network's stockholders who purchased stock during the period from April 18, 2002 through June 16, 2003. The complaint alleges that certain of our public disclosures during the class period were materially false and misleading in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder. The complaint also seeks compensatory damages, costs and attorney fees.

        We believe that these two class action lawsuits are without merit and intend to vigorously defend this litigation.

        From time to time, we are subject to lawsuits and claims that arise out of our operations in the normal course of business. We are plaintiffs or defendants in various litigation matters in the ordinary course of business, some of which involve claims for damages that are substantial in amount. We believe that the disposition of claims currently pending will not have a material adverse effect on our financial position or results of operations.

Item 4. Submission of Matters to a Vote of Security Holders

        There were no matters submitted to a vote of security holders during the fourth quarter of the fiscal year ended December 28, 2003.

PART II

Item 5.    Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

        The following table sets forth, for the fiscal quarters indicated, the high and low sales prices per share of our common stock, as reported by the New York Stock Exchange (NYSE).

        Our common stock has traded on the NYSE under the symbol "MRN" since our initial public offering on April 17, 2002. Prior to that time, there was no public trading market for our common stock.

        As of December 28, 2003, there were approximately 24 holders of record of our common stock, which numbers do not reflect stockholders who beneficially own common stock held in nominee or street name.

        We have never declared or paid cash dividends on our common stock. We currently intend to retain all future earnings for the operation and expansion of our business and, therefore, do not anticipate declaring or paying cash dividends on our common stock in the foreseeable future. Except as otherwise restricted by our current senior credit facility, any payment of cash dividends on our common stock will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, contractual restrictions and other factors deemed relevant by our Board of Directors. Our current senior credit facility prohibits us and our subsidiaries from declaring or paying any dividends or any other distributions without the consent of lenders holding more than 50% of the loans under the facility (or if a single lender holds more then 50% of the loans under the facility, the consent of that lender and at least one other lender is required), except that we and our subsidiaries may pay dividends or make other distributions to each other, except further that our operating subsidiary may pay dividends or make other distributions to us to be used to pay our operating expenses in an amount up to $500,000 in the aggregate in any fiscal year.

        We did not repurchase any shares of our common stock during the fourth quarter of the fiscal year ended December 28, 2003.
