on the first-half 
figures, Roche Chairman and CEO Franz B. Humer said, 'Roche can look back on a very successful first 
half-year, particularly in terms of its operating performance. Our core pharmaceuticals and diagnostics 
businesses grew faster than the market, and at the same time we significantly improved profitability. 
The integration of Chugai and the great success of new and established Roche products were both major 
contributors to the high rate of sales growth recorded for the half. Efforts to strategically reposition 
the Roche Group as a solidly financed healthcare leader with core businesses in pharmaceuticals and 
diagnostics are progressing as planned. We have made substantial progress in addressing problems from 
the past - the sale of the Vitamins Division, Igen and last year's financial results. Based on our results 
for the first six months, we expect to meet the full-year sales and earnings guidance we released early 
this year.'\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 \par}{\pard\f0\li0\ri0\sa360\sl360\fs22

The adjusted figures, which are used in the internal management of the Roche Group, represent the results 
of the Group's underlying on-going operations. They exclude special items and include only continuing 
businesses. See page 69 of the 2002 Annual Report for a full description of reported and adjusted results 
and page 27 of the Half-Year Report for a reconciliation. \line b) EBITDA: Earnings before 
interest and other financial income, tax, depreciation and amortisation, including impairment. This 
corresponds to operating profit before depreciation and amortisation, including impairment.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Roche 
Group} \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Sales and operating profit up significantly\line } In 
the first half of 2003 the Roche Group's two core businesses recorded sales totalling 13.9 billion Swiss 
francs. This is equivalent to a year-on-year growth rate of 17% in local currencies (+6% in CHF). Sales 
in the Pharmaceuticals Division advanced 21% in local currencies (+9% in CHF), and the Diagnostics Division 
posted a 7% increase in sales (-1% in CHF). Including revenues from the discontinuing Vitamins and Fine 
Chemicals Division, Group sales advanced 15% in local currencies (+4% in CHF).\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 The 
further marked increase in the Group's operating profitability is especially positive. Reported operating 
profit rose 44% in Swiss franc terms, to approximately 2.5 billion Swiss francs. This very strong increase 
was due partly to the substantial one-time costs reported during the same period last year in relation 
to a Genentech lawsuit. Even excluding special items and discontinuing operations, however, operating 
profits in Roche's core pharmaceuticals and diagnostics businesses increased in local currencies by 
a very substantial 27% and in Swiss franc terms by 15%, reaching a total of 2.8 billion Swiss francs. 
Sales growth, an improved gross profit margin and substantially lower net other operating expenses all 
contributed to this rise. Additional costs related to the integration of Chugai, the marketing of new 
products such as Pegasys and Fuzeon and the support of our development pipeline including activities 
connected with the development of compounds acquired through licensing transactions or research agreements 
were thus offset.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 The financial statements for the first 
half of 2003 show 
a net financial expense of roughly 370 million Swiss francs, compared with net financial income of about 
half a billion francs one year ago. The difference is explained by the one-time gain of 895 million 
Swiss francs recorded last year on the sale of LabCorp shares. Net income as reported in the half-year 
financial statements reached 1.3 billion Swiss francs, while adjusted net income totalled 1.6 billion, 
marking a return to a solid earnings performance compared with the second half of 2002. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Pharmaceuticals

On an adjusted basis.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Prescription medicines 
- sales grow ahead 
of the market} \line Sales in the Pharmaceuticals Division increased by an impressive 
21% in local currencies in the first half of 2003 (+9% in CHF), with Roche, Genentech and Chugai all 
contributing to growth. Sales of the Group's prescription medicines grew nearly three times as fast 
as the market. Even excluding Chugai, the division's prescription medicines business outpaced the global 
pharmaceuticals market. The operating profit margin on pharmaceuticals improved, despite the higher 
costs incurred for the launch of Pegasys and Fuzeon and despite continued generic erosion of Roaccutan/Accutane 
sales.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 The division posted solid sales results in all key 
regions. In North 
America, Japan and Europe prescription sales advanced ahead of the market. In Latin America sales declined 
significantly less than the market as a whole. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Oncology 
- strong 
sales and outstanding clinical results} \line Roche's cancer medicines generated sales 
of 2.9 billion Swiss francs in the first six months of the year, achieving a growth ratea) of 36%. Roche's 
leading oncology portfoliob) accounts for approximately one-third of total prescription drug sales. 
MabThera/Rituxan, Herceptin and Xeloda were the main growth drivers. MabThera/Rituxan, the world's first 
therapeutic monoclonal antibody for non-Hodgkin's lymphoma (NHL), continues to post strong double-digit 
sales growth. Sales of the product for both indolent and aggressive NHL are expected to benefit from 
recently published data from clinical trials. In addition, promising early data from phase II trials 
show MabThera/Rituxan to be both effective and well-tolerated in rheumatoid arthritis. Herceptin, a 
product prescribed for the targeted treatment of advanced breast cancer, likewise continued to experience 
strong double-digit sales growth in all key regions. Xeloda sales were also up significantly for the 
first six months of the year. This oral, tumour-activated medicine is used to treat breast and colorectal 
cancer. In May the National Institute for Clinical Excellence (NICE) in the United Kingdom endorsed 
the use of Xeloda in both these indications. Kytril, which is used to control nausea and vomiting, increased 
its share of the anti-emetics market, helped by a moderate rise in sales. These gains can be ascribed 
to the product's high efficacy, safety and convenience.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 a) 
All growth rates 
are based on local currencies.\line b) Oncology portfolio: MabThera/Rituxan, Herceptin, Xeloda, 
Bondronat, Kytril, Furtulon, Neupogen, NeoRecormon (25%), Roferon-A (60%), Neutrogin, Picibanil.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Anemia 
- patients benefit from new NeoRecormon dosing regimen} \line Sales of NeoRecormon, Roche's 
leading product for anemia, showed another strong increase in the first half of this year. NeoRecormon 
is now the European market leader for the treatment of anemia in patients with renal disease. In April 
the European authorities approved a new regimen of one dose every two weeks in stable dialysis patients. 
Safety concerns relating to a competitor's product had a positive impact on NeoRecormon sales. NeoRecormon 
is playing an increasingly important role in the management of anemia in cancer patients, a trend reflected 
by the 39% rise in sales of the product in this segment. In Japan Chugai's anti-anemia product Epogin 
generated 365 million Swiss francs in sales revenues.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Transplantation 
- outstanding efficacy and safety drive growth} \line Helped by a strong first-half performance, 
CellCept consolidated its position as the preferred agent for immunosuppressive therapy in transplant 
patients. Recent clinical data have reaffirmed the medicine's high efficacy and low toxicity. Treatment 
with CellCept has been shown to minimise the risk of patients developing post-transplant malignancies. 
Thanks to its convenience and high potency, Valcyte is on track to replace Cymevene as the standard 
of care for the treatment and prevention of cytomegalovirus eye infections (CMV retinitis) in immunocompromised 
patients. In May Valcyte was approved in Europe for use in solid organ transplant recipients, and US 
approval in this major indication is expected later this year.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Virology 
- Pegasys and Fuzeon successfully launched} \line Pegasys combined with Copegus, Roche's 
highly effective two-drug regimen for hepatitis C, is now approved in over 80 countries worldwide. Pegasys 
has already gained significant market share in many markets, including the United States. In the first 
half of this year, combined sales of Pegasys and Copegus had already reached 335 million Swiss francs, 
despite the fact that the products were not launched in France and Italy until April and June, respectively. 
A Japanese filing is currently receiving fast-track review, with approval expected by the end of this 
year. Fuzeon, the first HIV fusion inhibitor, was approved by the US and EU authorities in March and 
May, respectively, and was rolled out very quickly in both regions. Fuzeon prevents HIV from entering 
and infecting human cells. Production capacity for Fuzeon is being steadily expanded to meet the anticipated 
demand. Good progress is also being made in negotiations for reimbursement approval. Switzerland approved 
the product for marketing and reimbursement in May. Sales of the protease inhibitors Viracept, Invirase 
and Fortovase were down approximately 6% from the first half of 2002 as a result of further price reductions 
granted to developing countries and competitive pressure from new HIV medicines. Invirase and Fortovase 
have returned to growth (+15%) in the important US market, however, thanks to positive new data from 
clinical trials. Sales of Tamiflu rose 120% for the half as Japan experienced its worst flu outbreak 
in ten years. The product became available for the first time in Europe during the 2002-2003 flu season.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Other 
key products - Dilatrend continues to post strong growth} \line Rocephin sales declined 
as a result of growing pressure from generics in Europe and a modest first-quarter performance in the 
United States. However, the product still remains the world's number one parenteral antibiotic. As expected, 
sales of Roaccutan/Accutane fell significantly. Generic competition in the United States and Europe 
and a general downturn in the anti-acne segment both contributed to the decline. However, the product 
continues to command a 50% market share in both these regions. While Xenical sales were down for the 
period, they showed less of a decline than the market for prescription weight-loss medicines as a whole. 
One of the main reasons for the general downturn in this segment is the hesitancy of regulatory authorities 
to approve reimbursement. In the first half of this year Roche made further progress on this front, 
obtaining reimbursement approval for Xenical in Sweden and Switzerland. Data from an ongoing trial have 
shown that Xenical can reduce the risk of type 2 diabetes. Sales of Dilatrend, now the top-selling beta-blocking 
agent for chronic heart failure, hypertension and coronary artery disease, continue to grow by double-digits. 
The product has benefited from a wealth of positive clinical data, including the recently released results 
of a study in which Dilatrend was shown to save significantly more lives than a conventional beta-blocker. 
Roche and GlaxoSmithKline are co-developing Boniva (ibandronate), a potent new medicine for the treatment 
and prevention of osteoporosis. A once-daily oral formulation was recently approved in the United States 
and is now under review by the European regulatory authorities. Development work on additional formulations 
is progressing well. In June Genentech received FDA clearance to market Xolair, a monoclonal antibody 
for allergic asthma. It is the first of a new class of agents for the treatment of allergic diseases. 
A US launch is expected within the next few weeks.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Development 
projects on track - very good results seen in clinical trials} \line The first half of 
2003 was highlighted by impressive progress in Roche's development portfolio and the publication of 
convincing data on numerous projects. A number of Roche-managed projects advanced to the next phase 
of development. In addition, the company announced agreements to collaborate on a range of products, 
including an agreement to jointly develop and promote Chugai's highly promising new rheumatoid arthritis 
medicine, MRA. This is the first collaboration of its kind between Roche and Chugai. Under an agreement 
between Roche and Genentech, the two companies will jointly develop and commercialise Avastin, an extremely 
promising medicine for cancer. Data published recently by Genentech from a phase III study exceeded 
expectations, providing an impressive validation of Avastin's novel mechanism of action in colorectal 
cancer and possibly in other types of cancer. The FDA has included Avastin in its fast-track programme, 
designed to facilitate the development and expedite the approval of promising new medicines for life-threatening 
diseases. Work on other important projects in key therapeutic areas is moving ahead as planned. These 
include Tarceva and pemtumomab in oncology; Pegasys for hepatitis B and the second-generation HIV fusion 
inhibitor T-1249 in virology; ISA247 in transplantation medicine; and CERA for anemia.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Consumer 
health products - steady progress} \line Sales of Roche's non-prescription (OTC) medicines 
rose 18% in local currencies (+10% in CHF) to 868 million Swiss francs as a result of the integration 
of Chugai. After suffering from the effects of the economic crisis in Latin America, Roche Consumer 
Health returned to growth in the first half-year, with sales increasing 3% in local currencies in a 
flat market. Strong sales performances were reported in Asia and Eastern Europe. Roche's major OTC brands, 
particularly Redoxon and Bepanthen, posted above-average growth. Chugai's OTC sales in Japan were in 
line with expectations. The operating profit margin on OTC sales declined to 16.2%. Apart from negative 
foreign currency impacts, the lower profitability of Chugai's OTC business and investments to develop 
orlistat (Xenical) as an OTC product were the main factors for the decrease. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Diagnostics

the first half of 2003 sales by the Diagnostics Division increased 7% in local currencies (-1% in CHF), 
once again advancing well ahead of the in-vitro diagnostics market as a whole. The division was thus 
able to further expand its global market lead. Sales growth remained strongest in the division's two 
most profitable segments, Diabetes Care and Molecular Diagnostics' in-vitro diagnostics business. The 
division's operating profit margin again increased significantly, from 15.6% at the end of 2002 to 18.2%. 
Sales growth in the Asia-Pacific and Iberia regions was well into the double digits. Here, as in Europe 
and North America, revenues expanded far faster than the market. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Diabetes 
Care - acquisition of Disetronic strengthens strategic position } \line The acquisition 
of Disetronic - the world's second biggest manufacturer of insulin pumps - was a major strategic move 
towards strengthening the market leadership of Roche's Diabetes Care unit. The addition of this new 
business enables Roche to develop comprehensive solutions for the diagnosis, treatment and management 
of diabetes. Roche has initiated all necessary steps in response to complaints by the FDA regarding 
production processes and documentation at Disetronic. These issues were known to Roche at the time of 
the acquisition, and the Group is working closely with the FDA to resolve them. The planned launch of 
a new generation of insulin pumps in the second half of 2004 will not be affected. Owing in particular 
to the Accu-Chek systems Compact, Advantage and Active, Roche consolidated its lead in the blood glucose 
monitoring segment. Diabetes Care expects additional growth to be generated by the roll-out of new versions 
of its well-established Accu-Chek blood glucose meters and the launch of an improved test strip for 
Accu-Chek Compact. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Near Patient Testing - 
market leadership 
maintained} \line Roche Near Patient Testing maintained its market lead in coagulation 
monitoring and primary care (compact systems for doctors' offices). The upcoming roll-out of a new generation 
of urinalysis systems is expected to spur additional growth. Cardiac assays and the OMNI C blood gas 
analyser were once again among the unit's best-selling rapid diagnostic products for use in emergency 
rooms and intensive care units. Roche anticipates similarly strong demand for its newly introduced multifunctional 
OMNI S analyser. The non-clinical drugs-of-abuse testing and OPTI systems businesses were sold in the 
first quarter. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Centralized Diagnostics - above-average 
growth} \line Centralized 
Diagnostics outperformed the market by a substantial margin, with the Elecsys and Integra product lines 
once again delivering double-digit sales growth. The Modular Analytics SWA system also continues to 
be very well received in the marketplace. Sales of the highly innovative Elecsys proBNP, the first fully 
automated commercial test for diagnosing heart failure, are exceeding expectations. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Molecular 
Diagnostics - developing genetic tests for a wide range of diseases} \line Roche Molecular 
Diagnostics posted another double-digit (20%) rise in sales of in-vitro diagnostic tests. As expected, 
however, sales to industrial customers, which account for a relatively small percentage of revenues, 
declined further. Blood-screening tests and PCR-based tests for sexually transmitted diseases, HIV/AIDS 
and hepatitis C were the growth drivers in this business area. In May the FDA authorised the use in 
clinical trials of the first fully automated blood-screening test for West Nile virus, and in mid-July 
Roche launched a reliable test for the causative virus of severe acute respiratory syndrome (SARS) for 
use in research laboratories. The short development times for these two tests are further examples of 
the division's high capacity for innovation. Cobas TaqMan 48, which is now available in the United States, 
is the first PCR analyser tailored to small and medium-sized laboratories. The system can perform tests 
developed by customers as well as standard PCR-based assays. The GeneChip technology licensed-in from 
Affymetrix enables Roche to develop DNA microarrays for a wide range of diseases and establish new standards 
for genetic testing in routine clinical settings. AmpliChip CYP450 is the first product to result from 
this licensing agreement. It was launched in the United States in June, initially for use by certain 
specialist diagnostic laboratories. Five additional microarray-based products are slated for launch 
by the end of 2004. In addition, Roche has signed a cooperation agreement with Epigenomics to develop 
a range of tests for the early detection of cancers. The DNA methylation technology used by these tests 
marks a significant advance in diagnostic accuracy over earlier methods and complements the Group's 
PCR- and microarray-based technologies. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Applied 
Science - establishing 
itself despite weak market} \line Roche Applied Science experienced an overall decline 
in sales as a result of the still sluggish economic climate and the weakness of the biotech market, 
especially in the United States. This business unit has established itself globally as a partner in 
life science research and is focusing on the high-potential genomics and proteomics markets. Applied 
Science expects further growth to result from European approval of a new BSE test and from the launch 
at the end of 2003 of MagNA Pure Compact, a nucleic acid purification system that enables isolation 
and analysis of individual samples.\line \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Vitamins 
and Fine Chemicals Division - global downturn leads to modification of agreement; closing expected in 
third quarter} \line Progress has been made towards finalising the sale of the Vitamins 
and Fine Chemicals Division to DSM. The purchase price has been reduced by 200 million euros because 
of the continued global downturn in the market for vitamins. Accordingly, Roche has recorded an additional 
impairment charge of 375 million Swiss francs against net assets in its half-year financial statements. 
Until the transaction is closed, the division's results will continue to be included in the Group's 
consolidated financial statements, but will be excluded from the adjusted figures. Roche expects to 
complete the sale in the third quarter of 2003. No additional provisions have had to be recorded for 
the vitamin case.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Outlook} \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Roche 
Group - guidance reaffirmed} \line Barring unforeseen events, the Roche Group reaffirms 
the full-year sales and earnings guidance communicated early this year. Roche expects both sales and 
operating profit to increase by double-digits in local currencies. The operating profit margin is expected 
to at least remain stable compared with 2002. \par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Pharmaceuticals 
- innovative new medicines boost sales further} \line As already announced, the Pharmaceuticals 
Division expects to see a double-digit increase in full-year sales and operating profit in local currencies. 
The division remains committed to raising its operating profit margin towards 25% by the end of 2004. 
Its oncology portfolio, led by MabThera/Rituxan, Herceptin and Xeloda, will continue to be a key growth 
driver. The very good clinical data on Avastin suggest that Roche may soon have another major medicine 
in this important therapeutic area. In addition, the division anticipates strong growth from its newly 
launched products Pegasys and Fuzeon and from the established products NeoRecormon, Epogin and CellCept. 
\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 {\b Diagnostics - double-digit growth for full-year 
2003} \line Following 
its latest strategic moves - with Disetronic and Affymetrix - the Diagnostics Division is now more broadly 
positioned for continued growth and expansion into new markets. As a result, it is also ideally equipped 
to play an active role in shaping the diagnostics market and developing the emerging market for health 
information. The division plans to launch more than ten new products in the second half of the year. 
Helped by new product roll-outs and the inclusion of Disetronic in the consolidated results from May 
on, full-year sales and operating profit in the division are expected to rise by double-digits in local 
currencies. Roche Diagnostics also reaffirms its goal of achieving an operating profit margin of slightly 
over 20% in 2006.\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 Annex ( http://www.roche.com/mrhy03ane.pdf)\par}{\pard\f0\li0\ri0\sa360\sl360\fs22 The
