       	               3M Company and Subsidiaries
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                (Unaudited)

The interim consolidated financial statements are unaudited but, in the
opinion of management, reflect all adjustments necessary for a fair
presentation of the company's consolidated financial position, results of
operations and cash flows for the periods presented.  These adjustments
consist of normal, recurring items.  The results of operations for any
interim period are not necessarily indicative of results for the full
year. The interim consolidated financial statements and notes are
presented as permitted by the requirements for Quarterly Reports on Form
10-Q.  This Quarterly Report on Form 10-Q should be read in conjunction
with the company's consolidated financial statements and notes included in
its 2002 Annual Report on Form 10-K and its Current Report on Form 8-K
dated May 23, 2003 (which updated 3M's 2002 Annual Report on Form 10-K).
Part II, Item 1, Legal Proceedings, should also be read in conjunction
with the company's Quarterly Report on Form 10-Q for the period ended
March 31, 2003.

RECLASSIFICATIONS
Certain prior period Consolidated Statement of Cash Flows amounts within
the "Net cash provided by operating activities" section have been
reclassified to conform to the current year presentation.

ACCOUNTING PRONOUNCEMENTS
In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others." This interpretation elaborates on
the disclosures to be made by a guarantor in its interim and annual
financial statements concerning its obligations under certain guarantees
that it has issued.  It also clarifies (for guarantees issued after
January 1, 2003), that a guarantor is required to recognize, at the
inception of a guarantee, a liability for the fair value of the
obligations undertaken in issuing the guarantee.  For the six month period
ended June 30, 2003, 3M did not have any significant guarantees.

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-
Based Compensation-Transition and Disclosure.  An amendment of FASB
Statement No. 123."  The company is choosing to continue with its current
practice of applying the recognition and measurement principles of APB
No. 25, "Accounting for Stock Issued to Employees." The company has
adopted the disclosure requirements of SFAS No. 148. Pro forma amounts
based on the options' estimated fair value, net of tax, at the grant dates
for awards under the General Employees' Stock Purchase Plan and Management
Stock Ownership Program for the three and six month periods ended June 30,
2003 and 2002, follow.

Accounting Standards (SFAS) No. 143, "Accounting for Asset Retirement
Obligations," which was issued by the Financial Accounting Standards Board
(FASB). This statement establishes accounting standards for recognition
and measurement of a liability for an asset retirement obligation and the
associated asset retirement cost. The adoption of this standard did not
impact 3M's consolidated financial position or results of operations.

In January 2003, the FASB issued FASB Interpretation No. 46,
"Consolidation of Variable Interest Entities."  This interpretation
addresses the requirements for business enterprises to consolidate
related entities in which they are determined to be the primary economic
beneficiary as a result of their variable economic interests.  The
interpretation is intended to provide guidance in judging multiple
economic interests in an entity and in determining the primary
beneficiary.  The interpretation outlines disclosure requirements for
Variable Interest Entities (VIEs) in existence prior to January 31, 2003,
and outlines consolidation requirements for VIEs created after January
31, 2003.  The company has reviewed its major commercial relationships
and its overall economic interests with other companies consisting of
related parties, contracted manufacturing vendors, companies in which it
has an equity position, and other suppliers to determine the extent of
its variable economic interest in these parties.  As a result of this
review, 3M determined that no material entities are Variable Interest
Entities of 3M and it is not a primary economic beneficiary of any
Variable Interest Entity.

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities."  This statement amends
and clarifies financial accounting and reporting for derivative


 7

instruments, including certain derivative instruments embedded in other
contracts and for hedging activities under SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities."  SFAS No. 149 is
effective for certain contracts entered into or modified after June 30,
2003 and for hedging relationships designated after June 30, 2003.  This
standard is not expected to materially impact 3M's consolidated financial
position or results of operations.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
Financial Instruments with Characteristics of Both Liabilities and
Equity."  SFAS No. 150 requires that an issuer classify certain financial
instruments within its scope as a liability (or an asset in some
circumstances).  SFAS No. 150 is generally effective for financial
instruments entered into or modified after May 31, 2003, and otherwise is
effective for 3M at the beginning of the third quarter of 2003. This
standard is not expected to materially impact 3M's consolidated financial
position or results of operations.

In May 2003, Emerging Issues Task Force No. 00-21, "Accounting for
Revenue Arrangements with Multiple Deliverables" was finalized. This
addresses certain aspects of accounting by a vendor for arrangements
under which it will perform multiple revenue-generating activities.  The
guidance in the consensus is effective for revenue arrangements entered
into in fiscal periods beginning after June 15, 2003.  This standard is
not expected to materially impact 3M's consolidated financial position or
results of operations.

BUSINESS COMBINATIONS
In January 2003, 3M purchased an additional 25 percent interest of
Sumitomo 3M Limited from NEC Corporation for $377 million in cash.  As a
result of this acquisition, 3M now owns 75 percent of Sumitomo 3M
Limited.  Sumitomo Electric Industries, Ltd., a Japanese corporation,
owns the remaining 25 percent of Sumitomo 3M Limited.  Since all business
segments benefit from this combination, goodwill acquired in this
acquisition was allocated to 3M's seven business segments.  The purchase
price allocation at June 30, 2003, was preliminary.

During the first quarter of 2003, 3M (Display and Graphics Business)
finalized the purchase of Corning Precision Lens, Inc. (Precision
Optics), which was acquired in December 2002. The impacts of finalizing
the purchase price allocation, including a working capital adjustment and
payment of direct acquisition expenses, are displayed in the business
combination activity table that follows.

During the six-month period ended June 30, 2003, 3M entered into four
additional business combinations for $34 million, net of cash acquired.
1) 3M (Industrial Business) purchased 100 percent of the outstanding
shares of Solvay Fluoropolymers, Inc. (SFI), a previously wholly owned
subsidiary of Solvay America, Inc.  SFI is a manufacturer of
fluoroplastic products.
2) 3M (Display and Graphics Business) purchased Corning Shanghai
Logistics Company Limited, a previously wholly owned subsidiary of
Corning Incorporated. This business is involved in the distribution of
lens systems for projection televisions.

3) 3M (Safety, Security and Protection Services Business) purchased 100
percent of the outstanding shares of GuardiaNet Systems, Inc., a software
company.
4)  3M (Electro and Communications Business) purchased the outstanding
minority interest of Pouyet Communications, Inc. (PCI), an Indian
company.  PCI is a telecommunications supplier.

The business combination activity for the six-month period ending June
30, 2003, is summarized in the following table. Pro forma information
related to these acquisitions is not included because the impact of these
acquisitions, either individually or in the aggregate, on the company's
consolidated results of operations is not considered to be significant.

GOODWILL
As discussed in the "Business Segments" note, 3M realigned its business
segments and began reporting under this new structure effective January
1, 2003. The business segment realignment resulted in certain changes in
reporting units for 3M. Effective January 1, 2003, 3M has 18 reporting
units under the criteria set forth by Statement of Financial Accounting
Standards (SFAS) No. 142. SFAS No. 142 requires that goodwill be tested
for impairment when reporting units are changed.  During the first
quarter of 2003, the company completed its assessment of any potential
goodwill impairments under this new structure and determined that no
impairments existed.

The goodwill balance by business segment as of December 31, 2002 and June
30, 2003 follows.  Goodwill acquired in the first six months of 2003
totaled $304 million, with $8 million expected to be fully deductible for
tax purposes.  The increase in the goodwill balance during the six month
period ended June 30, 2003, primarily relates to 2003 business combination
activity and changes in foreign currency exchange rates.  The increase in
the goodwill balance in the second quarter of 2003 (when compared to the
first quarter of 2003) primarily relates to purchase accounting
refinements for the aforementioned acquisition of an additional 25 percent
of Sumitomo 3M Limited.

ACCOUNTING FOR DERIVATIVE INSTRUMENTS
The company uses interest rate swaps, currency swaps, and forward and
option contracts to manage risks generally associated with foreign
exchange rate, interest rate and commodity market volatility.

The table that follows provides the amounts recorded in cumulative
translation related to net investment hedging, and also provides cash flow
hedging instrument disclosures. Reclassification adjustments are made to
avoid double counting in comprehensive income items that are also included
as part of net income. The amount of the reclassification adjustment
recognized in other comprehensive income is equal to, but opposite in sign
from, the amount of the realized gain or loss in net income.

** Based on exchange rates at June 30, 2003, the company expects to
reclassify to earnings over the next 12 months a majority of the cash flow
hedging instruments after-tax loss of $43 million (with the impact largely
offset by foreign currency cash flows from underlying hedged items).

BUSINESS SEGMENTS
3M announced in September 2002 a strategic realignment of its
organization, designed to achieve faster growth and a closer focus on
its markets and customers.  This realignment resulted in seven
reportable business segments compared to the previous structure of six
reportable business segments.  Internal management reporting for the
new reportable business segments commenced on January 1, 2003.  Results
under the new structure for the three and six month periods ended June
30, 2003 and 2002, follow.

Corporate and Unallocated operating income principally includes corporate
investment gains and losses, certain derivative gains and losses,
insurance-related gains and losses, certain litigation expenses,
restructuring charges, and other miscellaneous items.  Because this
category includes a variety of miscellaneous items, it is subject to
fluctuation on a quarterly and annual basis. Significant items included
in Corporate and Unallocated for the periods presented follow.

Corporate and Unallocated for 2003 includes a pre-tax charge of $93
million recorded during the first quarter related to an adverse ruling
associated with a lawsuit filed against 3M in 1997 by LePage's Inc.


 13

Corporate and Unallocated in the first quarter of 2003 also includes
certain acquisition-related costs and respirator mask/asbestos litigation
expenses.

Corporate and Unallocated for 2002 includes charges related to employee
separation costs, accelerated depreciation and other business exit costs,
under the Company's previously announced restructuring plan. During the
first six months of 2002, 3M incurred pre-tax charges of $202 million
($148 million in the second quarter and $54 million in the first
quarter), related to this restructuring plan.

EARNINGS PER SHARE
The computations for basic and diluted earnings per share for each period
presented follow.

--------------------------------------------------------------------------


Certain stock options outstanding were not included in the computation of
diluted earnings per share because they would not have had a dilutive
effect (6.4 million average options for the three and six month period
ended June 30, 2003 and 3.2 million and 4.8 million for the three and six
month period ended June 30, 2002, respectively).  The conditions for
conversion related to the company's $639 million in aggregate face amount
of convertible notes were not met for the second quarter of 2003;
accordingly, there was no impact on 3M's second quarter or year to date
diluted earnings per share. If the conditions for conversion are met, 3M
may choose to pay in cash and/or common stock.

hedging instruments discussed in the "Accounting for Derivative
Instruments" section) were not material.

COMMITMENTS AND CONTINGENCIES
Discussion of legal matters is cross-referenced to this Quarterly Report
on Form 10-Q, Part II, Item 1, Legal Proceedings, and should be considered
an integral part of the interim consolidated financial statements.


SUBSEQUENT EVENT
On August 11, 2003, 3M's Board of Directors declared a two-for-one split
of the company's common stock.  The stock split will be in the form of a
stock dividend of one additional share for each share owned by stockholders
of record and each share held in treasury as of the close of business on
September 22, 2003 and will be distributed to such holders on
September 29, 2003.

Information (such as per share amounts, weighted average shares and
shares outstanding) has not been restated in the accompanying financial
statements and related notes to reflect this split.  This information
will be presented on a post split basis effective with third quarter 2003
reporting.  Information on a pro forma basis, showing the impact of this
split on all periods presented in this Form 10-Q, follows.

               REVIEW REPORT OF INDEPENDENT AUDITORS


To the Stockholders and Board of Directors of 3M Company:

We have reviewed the accompanying consolidated balance sheet of 3M Company
and its subsidiaries as of June 30, 2003, and the related consolidated
statements of income for each of the three-month and six-month periods
ended June 30, 2003 and 2002, and of cash flows for the six-month periods
ended June 30, 2003 and 2002. These interim financial statements are the
responsibility of the Company's management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical
procedures to financial data and making inquiries of persons responsible
for financial and accounting matters.  It is substantially less in scope
than an audit conducted in accordance with auditing standards generally
accepted in the United States of America, the objective of which is the
expression of an opinion regarding the financial statements taken as a
whole.  Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that
should be made to the accompanying interim consolidated financial
statements for them to be in conformity with accounting principles
generally accepted in the United States of America.

We previously audited, in accordance with auditing standards generally
accepted in the United States of America, the consolidated balance sheet
as of December 31, 2002, and the related consolidated statements of
income, of changes in stockholders' equity and comprehensive income, and
of cash flows for the year then ended (not presented herein); and in our
report dated February 10, 2003, except as to Note 12, for which the date
is May 22, 2003, relating to the consolidated financial statements in the
Current Report on Form 8-K, we expressed an unqualified opinion on those
consolidated financial statements. In our opinion, the information set
forth in the accompanying consolidated balance sheet as of December 31,
2002, is fairly stated in all material respects in relation to the
consolidated balance sheet from which it has been derived.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
         FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of
1995.  These statements may be identified by the use of words like
"plan," "expect," "aim," "believe," "project," "anticipate," "intend,"
"estimate," "will," "should," "could" and other expressions that indicate
future events and trends. All statements that address expectations or
projections about the future, including statements about the company's
strategy for growth, product development, market position, expenditures
and financial results, are forward-looking statements.

Forward-looking statements are based on certain assumptions and
expectations of future events that are subject to risks and
uncertainties. Actual future results and trends may differ materially
from historical results or those projected in any such forward-looking
statements depending on a variety of factors, including, but not limited
to, the following:

* The effects of, and changes in, worldwide economic conditions. The
company operates in more than 60 countries and derives more than half of
its revenues from outside the United States.  The company's business may
be affected by factors in the United States and other countries that are
beyond its control, such as downturns in economic activity in a specific
country or region; social, political or labor conditions in a specific
country or region; or potential adverse foreign tax consequences.

* Foreign currency exchange rates and fluctuations in those rates may
affect the company's ability to realize projected growth rates in its
sales and net earnings and its results of operations. Because the company
derives more than half its revenues from outside the United States, its
ability to realize projected growth rates in sales and net earnings and
results of operations could be adversely affected if the United States
dollar strengthens significantly against foreign currencies.

* The company's growth objectives are largely dependent on the timing and
market acceptance of its new product offerings, including its ability to
renew its pipeline of new products and to bring those products to market.
This ability may be adversely affected by difficulties or delays in
product development, such as the inability to: identify viable new
products; obtain adequate intellectual property protection; gain market
acceptance of new products, or successfully complete clinical trials and
obtain regulatory approvals. For example, new 3M pharmaceutical products,
like any pharmaceutical under development, face substantial risks and
uncertainties in the process of development and regulatory review.  There
are no guarantees that products will receive regulatory approvals or
prove to be commercially successful.


 20

* The company's future results are subject to fluctuations in the costs
of purchased components and materials due to market demand, currency
exchange risks, shortages and other factors. The company depends on
various components and materials for the manufacturing of its products.
Although the company has not experienced any difficulty in obtaining
components and materials, it is possible that any of its supplier
relationships could be terminated in the future. Any sustained
interruption in the company's receipt of adequate supplies could have a
material adverse effect on the company.  In addition, while the company
has a process to minimize volatility in component and material pricing,
no assurance can be given that the company will be able to successfully
manage price fluctuations due to market demand, currency risks, or
shortages, or that future price fluctuations will not have a material
adverse effect on the company.

* The possibility that acquisitions, divestitures and strategic alliances
may not meet sales and/or profit expectations. As part of the company's
strategy for growth, the company has made and may continue to make
acquisitions, divestitures and strategic alliances. However, there can be
no absolute assurance that these will be completed or beneficial to the
company.

* The company is the subject of various legal proceedings. The current
estimates of the potential impact on the company's consolidated financial
position, results of operations and cash flows for its legal proceedings
and claims are predictions made by the company about the future and
should be considered forward-looking statements. These estimates could
change in the future. For a more detailed discussion of the legal
proceedings involving the company, see the discussion of "Legal
Proceedings" in Part II, Item 1 of this Quarterly Report on Form 10-Q.

RESULTS OF OPERATIONS

Second Quarter
---------------
Overview:
3M had strong sales and earnings in the second quarter of 2003.  Sales in
the second quarter were a record $4.580 billion, with six of seven
business segments achieving worldwide volume growth.  The company reported
net income of $619 million, or $1.56 per diluted share, in the second
quarter of 2003, versus $466 million, or $1.18 per diluted share, in the
second quarter of 2002.  The second quarter of 2002 results include
special items (discussed later) that reduced earnings by 18 cents per
diluted share.

3M's five corporate initiatives, aimed at improving organic growth,
productivity and cash flow, continue to contribute to improved results.
While the company is on track to achieve its objective of at least $300
million in cost savings from these initiatives in 2003, 3M also faces many
challenges.  These challenges include continued economic uncertainty in
many parts of the world, possible downstream impacts from the SARS (Severe
Acute Respiratory Syndrome) outbreak, as well as an uncertain currency
environment.


 21

Special items:
The company did not have any significant special items during the second
quarter of 2003.  During the second quarter of 2002, under its previously
announced restructuring plan, 3M incurred pre-tax charges of $148 million
($73 million after-tax and minority interest, or $.18 per diluted share)
related to employee separation costs, accelerated depreciation charges and
other exit activities.  These charges have been classified as a component
of cost of sales ($91 million); selling, general and administrative
expenses ($56 million); and research, development and related expenses ($1
million).

Worldwide net sales for the second quarter of 2003 totaled $4.580 billion,
up 10.1 percent from the same period last year.  Volumes increased 5.6
percent, with 1.8 percentage points of this growth due to acquisitions.
The weaker U.S dollar increased worldwide sales by 4.6 percent, while
selling prices decreased sales by one-tenth of one percent.

In the United States, net sales totaled $1.925 billion, up 1.9 percent
from the same period last year.  Volumes increased 2.1 percent, benefiting
from 1.7 points of growth from acquisitions.  Display and Graphics,
Consumer and Office, Health Care, Safety, Security and Protection
Services, and Transportation all posted volume growth.  Selling prices
were down two-tenths of one percent.

International net sales totaled $2.655 billion, an increase of 16.9
percent in U.S. dollars.  Volumes increased 8.5 percent, which included
1.9 points of growth from acquisitions.  In the Asia Pacific area, volumes
increased almost 18 percent. Volume increased 7 percent in Japan and 28
percent in the rest of the Asia Pacific area. All business segments
experienced positive growth in Asia Pacific, with five of seven segments
posting double-digit sales growth.  In Latin America, volumes increased
9.7 percent, benefiting from the acquisition of Corning Precision Lens,
Inc.  In Europe, volumes increased six-tenths of one percent.  Selling
prices decreased international sales by one-tenth of one percent.
Currency effects increased international sales by 8.5 percent, driven by
positive currency translation of 16.4 percent in Europe and 3.5 percent in
the Asia Pacific area.  Currency translation negatively impacted sales in
Latin America by 8.9 percent.

Costs:
Cost of sales was 50.7 percent of sales, down about 3 percentage points
from the same quarter last year. Gross margins were positively impacted by
Six Sigma and other projects aimed at improving throughput, yield and
productivity.   Raw material costs were flat in the second quarter of
2003, despite significant cost pressures in certain commodities.
Corporate restructuring charges (totaling $91 million) negatively impacted
second quarter 2002 cost of sales.  Cost of sales includes manufacturing,
engineering and freight costs.

Selling, general and administrative (SG&A) expenses were 22.3 percent of
sales, down 1.1 percentage points from the second quarter of 2002. SG&A
expenses were $46 million higher than the same period last year, an
increase of 4.7 percent. This increase in SG&A dollar spending reflects
the impacts of currency translation, as well as 3M's continued investments
in advertising and merchandising.  Second quarter 2002 SG&A expenses
include corporate restructuring charges of $56 million.

Operating income:
Operating income was 21.0 percent of sales, compared with 16.5 percent in
the same period last year. This margin improvement was driven by higher
sales and increased productivity.  Second quarter 2003 results included
costs associated with additional employment reduction actions in the
United States and Europe, primarily in the Industrial and Electro and
Communications businesses. The second quarter of 2002 included $148
million of charges related to the corporate restructuring plan.

Interest expense and income:
Second quarter interest expense was $24 million, $4 million higher than in
the same period last year, with the increase primarily due to higher
average debt levels.  Interest income was $5 million, compared with $9
million in the same period last year, impacted by lower interest rates.

Provision for income taxes:
The worldwide effective income tax rate for the quarter was 33.0 percent,
up from 31.2 percent in the second quarter last year and 32.1 percent for
total year 2002. The company expects a rate in the 33 percent range for
the rest of 2003 due to taxes associated with repatriating cash from
outside the United States.

Minority interest:
Minority interest expense for the quarter was $12 million, compared with
income of $1 million in the same period last year. The increase primarily
related to higher profitability of Sumitomo 3M Limited (a Japanese
company), partially offset by a decrease in minority interest ownership
related to the purchase of an additional 25 percent of the shares of
Sumitomo 3M Limited in January 2003, and the purchase of the minority
interest shares of 3M Inter-Unitek GmbH in December 2002. In the second
quarter of 2002, Sumitomo 3M Limited profitability was negatively impacted
by the corporate restructuring plan.

Net income:
Net income for the second quarter of 2003 totaled $619 million, or $1.56
per diluted share, compared with $466 million, or $1.18 per diluted share,
in the same period last year.  The company estimates that currency effects


 23

increased net income for the quarter by about $31 million. This estimate
includes the effect of translating profits from local currencies into U.S.
dollars; the impact of currency fluctuations on the transfer of goods
between 3M entities and with third parties; and transaction gains and
losses, including derivative instruments designed to reduce exchange rate
risks.  These derivative instruments and other transaction impacts
decreased net income by an estimated $14 million in the second quarter of
2003.

First Six Months
----------------
Overview:
The company reported net income of $1.121 billion, or $2.83 per diluted
share, in the first six months of 2003, versus $918 million, or $2.32 per
diluted share, in the same period last year. Aided by an increase in
volumes and a weaker U.S. dollar, sales in the first six months of 2003
were $8.898 billion, up 10.5 percent from the same period last year, with
six of seven business segments achieving worldwide volume growth. 3M's
five corporate initiatives, aimed at improving organic growth,
productivity and cash flow, continue to contribute to improved results.

Special items:
As announced by 3M on March 26, 2003, a court issued an adverse ruling
associated with a lawsuit filed against 3M in 1997 by LePage's Inc.
During the first quarter of 2003, 3M recorded pre-tax charges of $93
million ($58 million after-tax, or $.15 per diluted share) related to
this proceeding.  The pre-tax charge of $93 million has been classified
as "Other expense" within operating income.

During the first six months of 2002, under its previously announced
restructuring plan, 3M incurred pre-tax charges of $202 million ($108
million after-tax and minority interest, or $0.27 per diluted share)
related to employee separation costs, accelerated depreciation charges and
other exit activities.  These charges have been classified as a component of
cost of sales ($121 million), selling, general and administrative expenses
($77 million) and research and development expenses ($4 million).

Worldwide sales for the first six months of 2003 totaled $8.898 billion,
up 10.5 percent from the same period last year.  Core volume increased 3.6
percent from the same period last year, with acquisitions contributing an


 24

additional 1.9 percent to growth.  Currency translation increased sales by
5.1 percent.

In the United States, sales for the first six months of 2003 totaled
$3.725 billion, an increase of 1.4 percent from the same period last year.
This growth was driven by acquisitions, which increased sales by 1.7
percent.  Pricing decreased sales in the United States by three-tenths of
one percent.  International sales for the first six months of 2003 totaled
$5.173 billion.  This increase in international sales was driven by core
volume growth of 6.7 percent.  Acquisitions increased international sales
by 2.0 percent. In the Asia Pacific area, volumes increased 18.6 percent.
All business segments experienced positive growth in Asia Pacific, with
six of seven segments posting double-digit sales growth.  In Latin
America, volumes increased 13.6 percent, benefiting from the acquisition
of Corning Precision Lens, Inc.  In Europe, volumes decreased two-tenths
of one percent.  Selling prices increased international sales by one-tenth
of one percent.  Currency effects increased international sales by 9.4
percent, driven by positive currency translation of 17.8 percent in Europe
and 6.1 percent in the Asia Pacific area.  Currency translation negatively
impacted sales in Latin America by 15.4 percent.

Costs:
Cost of sales was 51.0 percent of sales in the first six months of 2003,
down from 53.0 percent in the same period last year. Gross margins were
positively impacted by Six Sigma and other projects aimed at improving
throughput, yield and productivity.   Raw material costs were flat for the
first six months of 2003.  Corporate restructuring charges in the first
six months of 2002 (totaling $121 million) negatively impacted cost of
sales.  Cost of sales includes manufacturing, engineering and freight
costs.

Selling, general and administrative (SG&A) expenses were 22.3 percent of
sales, down from 23.0 percent in the same period last year. SG&A expenses
were $132 million higher than the same period last year, an increase of
7.1 percent. This increase in SG&A dollar spending reflects the impacts of
currency translation, as well as increased advertising and merchandising
spending. SG&A expenses for the first six months of 2002 include a charge
of $77 million relating to the corporate restructuring plan.

Operating income:
Operating income was 19.6 percent of sales, compared with 17.4 percent in
the same period last year.  This margin improvement was driven by higher
sales and increased productivity.  The first six months of 2003 included a
$93 million loss related to an adverse ruling associated with a lawsuit
filed by LePage's Inc.  The first six months of 2002 included $202 million
of charges related to the corporate restructuring plan.

Interest expense and income:
Interest expense in the first six months of 2003 was $47 million, $8
million higher than in the same period last year.  The increase was
primarily due to higher average debt levels compared with the same period
last year. Interest income was $11 million, compared with $18 million in
the same period last year, impacted by lower interest rates.


 25

Provision for income taxes:
The worldwide effective income tax rate for the six-month period ended
June 30, 2003 was 32.8 percent, up from 31.7 percent in the same period
last year and 32.1 percent for total year 2002.

Minority interest:
Minority interest expense was $26 million, compared with $23 million in
the same period last year. The increase primarily related to higher
profitability of Sumitomo 3M Limited (a Japanese company), partially
offset by a decrease in minority interest ownership related to the
purchase of an additional 25 percent of the shares of Sumitomo 3M Limited
in January 2003, and the purchase of the minority interest shares of 3M
Inter-Unitek GmbH in December 2002. In the first six months of 2002,
primarily in the second quarter, Sumitomo 3M Limited profitability was
negatively impacted by the corporate restructuring plan.

Net income:
Net income for the first six months of 2003 totaled $1.121 billion, or
$2.83 per diluted share, compared with $918 million, or $2.32 per diluted
share, in the same period last year.  The company estimates that currency
effects increased net income for the first six months by about $35
million. This estimate includes the effect of translating profits from
local currencies into U.S. dollars; the impact of currency fluctuations on
the transfer of goods between 3M entities and with third parties; and
transaction gains and losses, including derivative instruments designed to
reduce exchange rate risks.  These derivative instruments and other
transaction impacts decreased net income by an estimated $48 million in
the first six months of 2003.

Accounting pronouncements:
Information regarding accounting pronouncements is included in the Notes
to Consolidated Financial Statements.

RESTRUCTURING
The restructuring program actions were substantially completed by June
30, 2002.  The company estimates incremental savings under this plan of
approximately $100 million on a pre-tax basis in 2003, primarily in the
first half.  The majority of the savings will be from reduced employee
costs.  Selected information related to the restructuring follows.

PERFORMANCE BY BUSINESS SEGMENT
Following is a discussion of the global operating results of the company's
seven business segments in the second quarter and first six months of 2003
compared with the same periods last year.  As discussed in the "Business
Segments" note, 3M realigned its business segments and began reporting
under this new structure effective January 1, 2003.  With the exception of
the Electro and Communications business segment, all of the segments
showed sales growth in both the second quarter and the first six months of
2003.  All businesses benefited from the corporate initiatives, which are
designed to drive improvement in sales growth, productivity and cash flow.

In the Health Care business segment, volumes grew 5.6 percent in the
second quarter of 2003 and 5.2 percent in the first six months of 2003
when compared to the same periods last year.  Virtually all of the
businesses in the Health Care segment posted volume growth in the second
quarter and the six-month period ended June 30, 2003, with the largest
dollar growth in the medical and drug delivery systems businesses.
Operating income in Health Care increased by 23.4 percent to $263 million
in the second quarter of 2003 and by 15.8 percent to $501 million in the
first six months of 2003.

In September 2001, 3M signed an agreement with Eli Lilly and Company to
collaborate on resiquimod, a potential treatment for genital herpes.  In
the first quarter of 2003, Eli Lilly and 3M announced the suspension of
Phase III studies for resiquimod.  Lilly continues to evaluate its
strategic options with respect to this potential treatment.

3M is encouraged by the Phase III results for Aldara brand (Imiquimod)
Cream, 5%, in treating superficial basal cell carcinoma and actinic
keratosis.  In 2003, 3M submitted a supplemental new drug application
(sNDA) for Aldara cream for the treatment of actinic keratosis and has
also submitted an sNDA for Aldara cream for the treatment of superficial
basal cell carcinoma.

IVAX Corporation has agreed to assume exclusive rights to 3M's branded
health care respiratory products, together with related marketing and
sales personnel, in nine European countries.  The agreement covers a
"maintenance" medication (QVAR) used to prevent asthma attacks and a
"rescue" medication (Airomir) used to relieve acute asthma symptoms. 3M
will continue to manufacture and supply these products to IVAX and provide
transitional services for 12 months.  The transaction is pending
regulatory and other approvals.

In the Industrial business segment, volumes were basically flat in the
second quarter of 2003 and increased 1.9 percent in the first six months
of 2003.  Core volumes remain sluggish, especially in the United States
and Europe, with Asia Pacific continuing to grow.  Operating income in
Industrial decreased 22.3 percent to $102 million in the second quarter of
2003.  This decrease in profitability was driven by lower production in
factories and additional employee reduction costs incurred in the second
quarter of 2003.  Operating income in the first six months of 2003
decreased 3.3 percent from the same period last year.

In the Consumer and Office business segment, volumes increased
approximately 3 percent in both the second quarter and first six months of


 28

2003.  3M's construction and home improvement, stationery products and
home care businesses more than offset weakness in other product
categories.  Operating income in Consumer and Office was essentially
unchanged in the second quarter of 2003.  Increased advertising and
merchandising spending negatively impacted operating income in the second
quarter of 2003.  Operating income increased by 2.2 percent to $218
million during the first six months of 2003.

In the Display and Graphics business segment, volumes increased 21.9
percent in the second quarter of 2003 and 23.0 percent in the first six
months of 2003, with the December 2002 Corning Precision Lens acquisition
adding 9 percentage points of growth in the second quarter of 2003 and
nearly 10.5 percentage points of growth in the first six months of 2003.
Core volume growth in both the second quarter and first six months of 2003
was led by the Optical Systems business.  Operating income in Display and
Graphics increased 43.1 percent in the second quarter of 2003 and 48.2
percent in the first six months of 2003.

In the Electro and Communications business segment, volumes declined 6.8
percent in the second quarter of 2003 and 6.0 percent in the first six
months of 2003.  This volume decrease reflects continuing weakness in the
global telecommunications industry.  Operating income of the Electro and
Communications business segment declined about 10 percent in both the
second quarter and first six months of 2003, largely due to lower sales.

In the Safety, Security and Protection Services business segment, volumes
increased 11.0 percent in the second quarter of 2003 and 8.1 percent in
the first six months of 2003.  This volume increase was fueled by strong
demand for 3M's respiratory protection products, as well as increased
global demand for safety products and solutions.  Operating income in this
business segment increased by 42.4 percent to $131 million in the second
quarter of 2003 and by 32.3 percent to $236 million for the first six
months of 2003.

In the Transportation business segment, volumes increased 7.1 percent in
the second quarter of 2003 and 4.4 percent in the first six months of
2003.  This growth was driven by both the automotive aftermarket and the
automotive OEM businesses.  Operating income in Transportation increased
more than 18 percent in both the second quarter of 2003 and the first six
months of 2003.

FINANCIAL CONDITION AND LIQUIDITY
The company's financial condition and liquidity remain strong. Various
assets and liabilities, including cash and short-term debt, can fluctuate
significantly from month to month depending on short-term liquidity needs.
Working capital (defined as current assets minus current liabilities)
totaled $2.210 billion at June 30, 2003, increasing $608 million from
December 31, 2002.  This increase was largely related to an increase in
current assets, primarily due to the reclassification of certain insurance
receivables from long-term to current and an increase in various prepaid
items, as well as an increase in cash as of June 30, 2003.

The accounts receivable turnover index (defined as quarterly net sales
divided by ending accounts receivable, multiplied by 4) totaled 6.61 at
June 30, 2003, compared with 6.55 at December 31, 2002, and an improvement


 29

from 5.95 at June 30, 2002.  The inventory turnover index (defined as
quarterly factory cost divided by ending inventory, multiplied by 4)
continues to improve.  The inventory turnover index was 4.47 at June 30,
2003, an improvement from 4.17 at December 31, 2002, and 4.27 at June 30,
2002.

Net cash provided by operating activities totaled $1.890 billion in the
first six months of 2003, an increase of $294 million from the same period
last year, driven by higher net income along with certain tax timing
benefits.  Restructuring-related cash payments made by 3M totaled $36
million in the first six months of 2003, compared with $239 million in the
same period last year.  Restructuring-related cash payments made by 3M
related to the 2001 corporate restructuring plan are not expected to be
significant in the future.  Pension funding decisions, additional tax
timing differences, and other items could significantly impact cash flows
in the second half of 2003.

There were several legal proceeding developments during the first six
months of 2003.  As discussed earlier, in the first quarter of 2003, the
company recorded a $93 million pre-tax charge related to an adverse
ruling associated with a lawsuit filed against 3M in 1997 by LePage's
Inc.  At the end of the first quarter of 2003, the company also increased
its respirator mask/asbestos liabilities by $100 million and its related
insurance receivables by $94 million, resulting in $6 million of pre-tax
expense being recorded.  For a more detailed discussion of these and other
legal proceedings, refer to Part II, Item 1, Legal Proceedings, of this
Quarterly Report on Form 10-Q and 3M's first quarter 2003 Form 10-Q. 3M's
insurance recoveries, net of claims paid, related to the mammary implant
matter, resulted in $10 million of net cash inflows in the first half of
2003, compared with $27 million of net cash inflows in the first half of
2002.  Because most of the company's implant liabilities have been paid,
receipt of related insurance recoveries will increase future cash flows.

Cash used in investing activities totaled $614 million in the first six
months of 2003, compared with $328 million in the same period last year.
Capital expenditures for the first six months of 2003 were $264 million, a
decrease of $99 million from the same period last year. Capital
expenditures are expected to total approximately $750 million to $800
million during 2003, as the company anticipates capital spending to ramp
up later in the year. Cash used for acquisitions of businesses totaled
$424 million in the first six months of 2003, with $377 million related to
the purchase of an additional 25 percent ownership in Sumitomo 3M Limited.
The company is actively considering additional acquisitions.

Financing activities in the first six months of 2003 for both short-term
and long-term debt included net cash outflows of $349 million, compared
with net cash outflows of $285 million in the same period last year.  The
cash flow decrease in net short-term debt of $328 million includes the
portion of short-term debt with original maturities of 90 days or less.
Repayment of other debt of $328 million includes $220 million of
commercial paper having original maturities greater than 90 days and the
repayment of a $100 million medium term note.  Proceeds from other debt of
$307 million primarily related to commercial paper having original
maturities greater than 90 days.


 30

Total debt decreased $356 million from December 31, 2002. As of June 30,
2003, total debt was 30 percent of total capital, down from 36 percent as
of December 31, 2002.  The company believes its strong credit rating
provides ready and ample access to funds in the global capital markets.
The company's available short-term lines of credit facilities have not
materially changed since December 31, 2002. In March 2003, the company
completed its annual renewal of $565 million of certain short-term lines
of credit.  While the previous agreement would require repayment of debt
based on ratings triggers, the new agreement has a covenant that indicates
that 3M is not to exceed a funded debt to capital limit of 60 percent
(capital defined as funded debt plus stockholders' equity).

Treasury stock repurchases for the first six months of 2003 were $280
million, compared with $705 million in the same period last year. The
company repurchased about 2.2 million shares of common stock in the first
six months of 2003, compared with about 6.0 million shares in the same
period last year.  In November 2001, the Board of Directors authorized the
repurchase of up to $2.5 billion of the company's stock between January 1,
2002 and December 31, 2003.   As of June 30, 2003, about $1.3 billion
remained authorized for repurchase.  Stock repurchases are made to support
the company's stock-based compensation plans and for other corporate
purposes.

Cash dividends paid to shareholders totaled $515 million in the first six
months of 2003, compared with $483 million in the same period last year.
In February 2003, the quarterly dividend was increased by 6.5 percent to
66 cents per share, marking the 45th consecutive annual dividend increase
for 3M.

Included in the financing section of the Consolidated Statement of Cash
Flows is $23 million classified as "Other - net".  This category
represents changes in cash overdraft balances and principal payments for
capital leases.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the context of Item 3, market risk refers to the risk of loss arising
from adverse changes in financial and derivative instrument market rates
and prices, such as fluctuations in interest rates and foreign-currency
exchange rates.  For a discussion of sensitivity analysis related to
these types of market risks, refer to Part II, Item 7A, Quantitative and
Qualitative Disclosures About Market Risk, in 3M's Annual Report on Form
10-K for the year ended December 31, 2002 and its Current Report on Form
8-K dated May 23, 2003 (which updated 3M's 2002 Annual Report on Form
10-K). The company believes that there have been no material changes in
these market risks since year-end 2002.

ITEM 4.  CONTROLS AND PROCEDURES

a.  The company carried out an evaluation, under the supervision and with
the participation of the company's management, including the company's
Chief Executive Officer and Chief Financial Officer, of the effectiveness
of the design and operation of the company's "disclosure controls and
procedures" (as defined in the Exchange Act Rule 13a-15(e)) as of the end
of the period covered by this report.  Based upon that evaluation, the
Chief Executive Officer and Chief Financial Officer concluded that the
company's disclosure controls and procedures are effective in timely
alerting them to material information relating to the company (including
its consolidated subsidiaries) required to be included in the company's
periodic SEC filings.

b.  There was no significant change in the company's internal controls
over financial reporting, that occurred during the company's most
recently completed fiscal quarter, that has materially affected, or is
reasonably likely to materially affect, the company's internal control
over financial reporting.

                      PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

A description of the significant legal proceedings in which the company is
involved, both in general and with respect to specific matters, is
contained in the company's Annual Report on Form 10-K for the period
ending December 31, 2002, the company's Current Report on Form 8-K dated
May 23, 2003 (which updated the company's 2002 Annual Report on Form 10-
K), and the company's Quarterly Report on Form 10-Q for the period ending
March 31, 2003 (collectively the "Reports"). This section describes
significant developments since the preparation of the Reports and should
be read with reference to them. Unless specifically indicated, all
previously reported matters remain pending.

Breast Implant Insurance Recovery Litigation
--------------------------------------------
As previously reported, the Minnesota Supreme Court granted the company's
petition for review permitting the company to appeal the Court of
Appeal's decision in the breast implant insurance coverage litigation.
Oral arguments were held on June 3, 2003.  The company expects a decision
from the Minnesota Supreme Court later in 2003.

Antitrust Litigation
---------------------
The company filed its petition requesting the United States Supreme Court
to review the Third Circuit's ruling in the LePage's case on June 20,
2003.  The Supreme Court is not expected to act upon the company's
petition until the fall of this year at the earliest. During the second
quarter and in August of 2003, certain tape purchasers filed four additional
purported class actions against the company. Of the seven class actions filed
after the LePage's verdict (the four mentioned above and three previously
reported), the plaintiff appealed summary judgment in the company's favor
in one; the company moved to dismiss three others, in one of which the
court denied the company's motion while pre-trial proceedings related to
the plaintiff's request for class certification are occurring; and the
court stayed another one pending the outcome of the company's petition
for Supreme Court review of the LePage's case; and the company is reviewing
the complaints in two of the most recently filed cases.

Respirator Mask/Asbestos/Litigation
-----------------------------------
As of June 30, 2003, the company is a named defendant, with multiple co-
defendants, in numerous lawsuits in various courts that purport to
represent approximately 82,700 individual claimants. The company continued
to experience an increase in the number of claims and an increase in the
proportion of silica-related claims in the second quarter of 2003. The
company believes that the increased number of claims filed over the past
three quarters is due to claimants filing claims before recent and
anticipated tort reform legislation becomes effective and that many of
these newer claims are asserted on behalf of asymptomatic claimants. As of
June 30, 2003, the company has accrued liabilities of $211 million and


 33

receivables for the probable amount of insurance recoveries of $357
million related to this litigation.  Such accruals are subject to the
various factors previously disclosed.

Environmental Matters
----------------------
As previously reported, the company has been voluntarily cooperating with
ongoing reviews by the U.S. Environmental Protection Agency (EPA) and
international agencies of possible environmental and health effects of
perfluorooctanyl chemistry. The previously disclosed EPA consent order
negotiating process concerning one perfluorooctanyl compound is in
progress.

The company moved to dismiss the complaint and the class action
allegations in a purported class action previously reported that was
filed against the company by a former employee in the Circuit Court of
Morgan County, Alabama.

As previously reported, the company entered into a voluntary agreement
with the EPA under both an "Agreement for TSCA Compliance" and the EPA's
Incentives for Self Policing Policy. The company voluntarily conducted
auditing under the Toxic Substances Control Act (TSCA) of its facilities
and business units. As part of that auditing, the company identified
studies relating to perfluorooctanyl and other chemistries that
potentially could be subject to notification under TSCA section 8(e)
under current EPA guidelines. An agreement in principle governing the
first two phases of that section 8(e) audit involving a penalty of
approximately $222,000 was previously reported. The company has now
reached an agreement in principle encompassing all three phases of the
section 8(e) auditing under which the company would pay a total of
approximately $380,000 in penalties. The proposed agreement also
contemplates approximately $75,000 in additional penalties related to
other TSCA notification requirements and economic benefit related thereto
and limited additional section 8(e) auditing the results of which will be
subject to the same stipulated penalty schedule if reported to the EPA
within nine months of execution of the consent agreement.
