                               TO THE STOCKHOLDERS

For the six months  ended June 30,  2007,  the net asset value per common  share
increased by 11.3%, while the investment return to our stockholders was 9.2%. By
comparison,  the  rate of  return  (including  income)  for our  benchmark,  the
Standard & Poor's 500 Stock Index,  was 7.0%.  For the twelve  months ended June
30, 2007, the return on the net asset value per Common Share was 23.0%,  and the
return to our stockholders  was 21.6%;  these compare with a return of 20.5% for
the S&P 500.  During  each  period,  the  discount  at which our  shares  traded
continued to fluctuate and on June 30, 2007, it was 10.2%.

As set forth in the accompanying  financial statements  (unaudited),  as of June
30,  2007,  the  net  assets  applicable  to the  Company's  Common  Stock  were
$1,319,084,730 equal to $45.14 per Common Share.

The increase in net assets  resulting  from  operations for the six months ended
June 30, 2007 was  $133,915,605.  During this period,  the net realized  gain on
securities   sold  was   $128,919,725,   and  the  increase  in  net  unrealized
appreciation  was  $3,755,733.  Net  investment  income  for the six  months was
$7,190,147, and distributions to Preferred Stockholders amounted to $5,950,000.

During  the six  months,  364,300  shares of the  Company's  Common  Stock  were
repurchased  for  $14,343,113  at an average  discount  from net asset  value of
10.3%.

The  year to date  has  produced  meaningful  capital  gains,  though  it may be
difficult to sustain this  performance  over the balance of the year. One of the
main concerns is rising interest rates,  which reflect the impact of higher fuel
and food costs, among other factors, on inflation.  Higher borrowing costs could
dampen  the flow of  deals,  which is  thought  to be an  important  part of the
foundation currently supporting equities.

Although it's  difficult to argue that stocks are now  undervalued,  if interest
rates  are  trending  up,  sufficient  liquidity  appears  to be  available,  at
compelling  prices, to generally  support financial assets.  Despite the housing
slump and its attendant  subprime loan  problems,  the U.S.  economy seems to be
expanding  again.  Jobless claims and  unemployment  remain  relatively low, the
trade deficit appears to have stabilized, the dollar's decline has been orderly,
and global growth remains robust.

We are pleased to report that,  on July 11, 2007,  Messrs.  Rodney B. Berens and
Daniel M.  Neidich  were  appointed  to the Board of  Directors.  Mr.  Berens is
founding partner of Berens Capital  Management LLC and previously served as Head
of Global Equities at Salomon  Brothers and as a member of the firm's  Operating
Committee.  Mr. Neidich is founding  partner and Co-Chief  Executive  Officer of
Dune Capital  Management LP. and previously served as a member of Goldman Sachs'
Management Committee,  co-head of its Merchant Banking Division, and Chairman of
the Whitehall  Investment  Committee.  Messrs.  Berens and Neidich each serve as
directors  or  trustees  of  numerous  business,   community,  and  eleemosynary
organizations.  Their familiarity with investment  management and the securities
industries should be of great value to the Company in the future.

We are also pleased to report that Joseph T. Stewart, Jr., a member of the Board
of  Directors  of the  Company  since  1987,  has been  appointed  by his fellow
independent  directors to serve as the Company's  Lead  Independent  Director in
order to maintain good governance  practices in view of combining the offices of
the Chairman and Chief Executive Officer at the Company's recent annual meeting.

Information about the Company,  including our investment  objectives,  operating
policies and procedures, investment results, record of dividend and distribution
payments,  financial reports and press releases,  is on our website and has been
updated  through  June  30,  2007.  It  can  be  accessed  on  the  internet  at

reported on that day and other securities traded in the over-the-counter  market
are  valued  at the last bid price  (asked  price for  options  written)  on the
valuation  date.  Securities  traded  primarily in foreign markets are generally
valued at the  preceding  closing price of such  securities on their  respective
exchanges  or markets.  If,  after the close of the foreign  market,  conditions
change significantly, the price of certain foreign securities may be adjusted to
reflect fair value as of the time of the valuation of the portfolio. Investments
in money  market  funds are  valued at their net  asset  value.  The  restricted
security is valued at par value (cost), divided by the conversion price of $6.00
multiplied by the last reported sales price of the publicly  traded common stock
of the corporation.

b. OPTIONS The Company may purchase and write (sell) put and call  options.  The
risk  associated  with  purchasing  an option is that the Company pays a premium
whether or not the option is exercised. Additionally, the Company bears the risk
of loss of the premium and a change in market value should the  counterparty not
perform under the contract.  Put and call options purchased are accounted for in
the same manner as portfolio securities.  Premiums received from writing options
that expire  unexercised  are treated by the Company on the  expiration  date as
realized gains from investments. The difference between the premium received and
the amount paid on effecting a closing purchase transaction, including brokerage
commissions, is also treated as a realized gain, or, if the premium is less than
the amount paid for the closing purchase  transaction,  as a realized loss. If a
call option is exercised,  the premium is added to the proceeds from the sale of
the underlying  security in determining  whether the Company has realized a gain
or loss.  If a put option is exercised,  the premium  reduces the cost basis for
the  securities  purchased  by the  Company.  The Company as writer of an option
bears the  market  risk of an  unfavorable  change in the price of the  security
underlying the written option.

c. FEDERAL INCOME TAXES The Company's  policy is to fulfill the  requirements of
the Internal  Revenue Code applicable to regulated  investment  companies and to
distribute substantially all taxable income to its stockholders. Accordingly, no
provision for Federal income taxes is required.

d. INDEMNIFICATIONS In the ordinary course of business,  the Company enters into
contracts  that contain a variety of  indemnifications.  The  Company's  maximum
exposure under these arrangements is unknown.  However,  the Company has not had
prior claims or losses pursuant to these indemnification  provisions and expects
the  risk  of loss  thereunder  to be  remote.

e.  OTHER  As  customary  in  the  investment   company   industry,   securities
transactions   are  recorded  as  of  the  trade  date.   Dividend   income  and
distributions to stockholders are recorded as of the ex-dividend dates. Interest
income,  adjusted for  amortization of discount and premium on  investments,  is
earned from  settlement  date and is  recognized on the accrual  basis.  Cost of
short-term investments represents amortized cost.

2. CAPITAL STOCK AND DIVIDEND  DISTRIBUTIONS  - The authorized  capital stock of
the Company consists of 50,000,000 shares of Common Stock,  $1.00 par value, and
10,000,000  shares of  Preferred  Stock,  $1.00 par value,  of which  29,224,898
shares and 8,000,000 shares, respectively, were outstanding at June 30, 2007.

On September 24, 2003, the Company issued and sold 8,000,000 shares of its 5.95%
Cumulative Preferred Stock, Series B in an underwritten  offering. The Preferred
Shares are noncallable  for 5 years and have a liquidation  preference of $25.00
per share plus an amount equal to accumulated  and unpaid  dividends to the date
of redemption.  The underwriting discount and other expenses associated with the
Preferred  Stock  offering  amounted to  $6,700,000  and were charged to paid-in
capital.

The Company is required to allocate  distributions  from long-term capital gains
and other  types of income  proportionately  among  holders  of shares of Common
Stock and  Preferred  Stock.  To the  extent  that  dividends  on the  shares of
Preferred  Stock are not paid from long-term  capital  gains,  they will be paid
from ordinary income or net short-term  capital gains or will represent a return
of capital.

     Under the  Investment  Company  Act of 1940,  the  Company is  required  to
maintain  an  asset  coverage  of at  least  200% for the  Preferred  Stock.  In
addition,  pursuant to the Rating Agency Guidelines,  the Company is required to
maintain a certain  discounted  asset  coverage for its portfolio that equals or
exceeds the Basic Maintenance Amount under the guidelines established by Moody's
Investors  Service,  Inc.  The  Company  has met  these  requirements  since the
issuance of the Preferred Stock. If the Company fails to meet these requirements
in the future and does not cure such  failure,  the  Company  may be required to
redeem,  in whole or in part, shares of Preferred Stock at a redemption price of
$25.00 per share plus accumulated and unpaid dividends (whether or not earned or
declared).  In  addition,  the  Company's  failure to meet the  foregoing  asset
coverage  requirements  could restrict its ability to pay dividends on shares of
Common  Stock and could lead to sales of  portfolio  securities  at  inopportune
times.

The holders of Preferred  Stock have voting  rights  equivalent  to those of the
holders of Common Stock (one vote per share) and, generally,  vote together with
the holders of Common Stock as a single class.

At all times, holders of Preferred Stock will elect two members of the Company's
Board of Directors and the holders of Preferred  and Common  Stock,  voting as a
single class,  will elect the remaining  directors.  If the Company fails to pay
dividends  on  the  Preferred  Stock  in an  amount  equal  to two  full  years'
dividends,  the  holders  of  Preferred  Stock  will  have the  right to elect a
majority of the  directors.  In  addition,  the  Investment  Company Act of 1940
requires that approval of the holders of a majority of any outstanding Preferred
Shares, voting separately as a class, would be required to (a) adopt any plan of
reorganization  that would adversely affect the Preferred Stock and (b) take any
action  requiring a vote of security  holders,  including,  among other  things,
changes in the Company's subclassification as a closed-end investment company or
changes in its fundamental investment policies.

The Company  classifies its Preferred Stock pursuant to the requirements of EITF
D-98,  Classification  and Measurement of Redeemable  Securities,  which require
that  preferred  stock for which its  redemption  is  outside  of the  company's
control should be presented outside of net assets in the statement of assets and
liabilities.

and book purposes are substantially the same.

3.  OFFICERS'  COMPENSATION  - The  aggregate  compensation  paid by the Company

cover) amounted to $3,636,250.

than  short-term  securities and options) for the six months ended June 30, 2007
amounted to $334,626,356 and $345,148,409.

5.   BENEFIT   PLANS  -  The  Company  has  funded   (Qualified)   and  unfunded
(Supplemental)  noncontributory  defined  benefit  pension  plans that cover its
employees.  The plans  provide  defined  benefits  based on years of service and
final  average  salary with an offset for a portion of social  security  covered
compensation.  The components of the net periodic  benefit cost of the plans for
the six months ended June 30, 2007 were:

                     Service cost                        $150,780
                     Interest cost                        360,149

                     Net periodic benefit cost (income)  ($56,608)
                                                          =======

The Company also has funded and unfunded defined  contribution thrift plans that
are available to its  employees.  The  aggregate  cost of such plans for the six
months ended June 30, 2007 was $449,881. The unfunded liability at June 30, 2007
was $3,306,942.

Effective  December 31, 2006, the Company adopted the recognition  provisions of
Financial  Accounting Standards Board ("FASB") Statement of Financial Accounting
Standards No. 158  "Employers'  Accounting for Defined Benefit Pension and Other
Postretirement  Plans"  ("FAS158") which was released on September 2006. FAS 158
improves financial  reporting by requiring employers to recognize the overfunded
or underfunded  status of a defined benefit  postretirement  plan as an asset or
liability in the statement of assets and liabilities and to recognize changes in
funded status in the year in which the changes occur through other comprehensive
income.

6.  OPERATING  LEASE  COMMITMENTS  - In July 1992,  the Company  entered into an
operating  lease  agreement  for office space which expires on December 31, 2007
and provided for future rental payments in the aggregate amount of approximately
$5.6 million. The lease agreement contains a clause whereby the Company received
a  specified  number  of  months of free rent  beginning  in  December  1992 and
escalation clauses relating to rent charges,  operating costs, and real property
taxes.

In January 2003, the Company extended a sublease agreement  (originally  entered
into in March 1996) which  expires on December  31, 2007 and provides for future
rental  receipts.  Minimum rental receipts under the sublease are  approximately
$254,000 in 2007.  The Company will also be charged its  proportionate  share of
operating expenses and real property taxes under the sublease.

Net rental expense approximated $156,000 for the six months ended June 30, 2007.
On a gross basis,  minimum  rental  commitments  under the  operating  lease are
approximately $505,000 in 2007.

In June 2007,  the Company  entered into an operating  lease  agreement  for new
office  space which  expires in February  2018 and  provides  for future  rental
payments in the  aggregate  amount of  approximately  $10.8  million.  The lease
agreement  contains  clauses  whereby  the  Company  receives  free  rent  for a
specified   number  of  months  and  credit  towards   construction   of  office
improvements,  and incurs  escalations  annually relating to operating costs and
real property  taxes and to annual rent charges  beginning in February 2013. The
Company has the option to renew the lease after  February 2018 for five years at
market rates.

Minimum rental  commitments  under the operating  lease are  approximately  $0.9
million in 2008 and $1.0 million per annum in 2009 through 2012, $1.1 million in
2013 through 2017 and $0.1 million in 2018.

7. RECENT  ACCOUNTING  PRONOUNCEMENTS - On September 20, 2006, the FASB released
Statement of Financial  Accounting  Standards No. 157 "Fair Value  Measurements"
("FAS 157"). FAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value,  and requires  additional  disclosures
about fair-value measurements. The application of FAS 157 is required for fiscal
years  beginning after November 15, 2007 and interim periods within those fiscal
years.  Management  does not believe that the  application of this standard will
have a material impact on the financial statements of the Company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

To the Board of Directors and Stockholders of
GENERAL AMERICAN INVESTORS COMPANY, INC.
     We have reviewed the  accompanying  statement of assets and  liabilities of
General  American   Investors   Company,   Inc.,   including  the  statement  of
investments,  as of June 30, 2007, and the related  statements of operations and
changes in net assets and financial  highlights  for the six-month  period ended
June 30, 2007.  These  financial  statements  and financial  highlights  are the
responsibility of the Company's management.
     We  conducted  our review in  accordance  with the  standards of the Public
Company  Accounting  Oversight  Board  (United  States).  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  in
accordance with the standards of the Public Company Accounting  Oversight Board,
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 review,  we are not aware of any material  modifications  that
should be made to the interim financial statements referred to above for them to
be in conformity with  accounting  principles  generally  accepted in the United
States.
     We have previously  audited, in accordance with the standards of the Public
Company  Accounting  Oversight Board, the statement of changes in net assets for
the year ended  December 31, 2006 and financial  highlights for each of the five
years in the period then ended and in our report,  dated  January 17,  2007,  we
expressed an  unqualified  opinion on such  financial  statements  and financial
highlights.
