                               TO THE STOCKHOLDERS

For the nine months ended  September  30,  2006,  the  investment  return to our
stockholders   was   9.5%   (assuming   reinvestment   of  all   dividends   and
distributions).  The net asset  value per Common  Share  increased  by 5.1%.  By
comparison,  the  rate of  return  (including  income)  for our  benchmark,  the
Standard  & Poor's  500 Stock  Index,  was 8.5%.  For the  twelve  months  ended
September 30, 2006, the return to our  stockholders was 14.5%, and the return on
the net asset value per Common  Share was 7.9%;  these  compare with a return of
10.7% for the S&P 500.  During  each  period,  the  discount at which our shares
traded continued to fluctuate and at September 30, 2006, it was 7.8%.

As set  forth  in  the  accompanying  financial  statements  (unaudited),  as of
September 30, 2006, the net assets applicable to the Company's Common Stock were
$1,163,557,535, equal to $40.86 per Common Share.

The increase in net assets  resulting from  operations for the nine months ended
September 30, 2006 was $55,739,257. During this period, the net realized gain on
securities sold was $75,265,381, and the decrease in net unrealized appreciation
was $18,062,829.  Net investment income for the nine months was $7,461,705,  and
distributions to Preferred Stockholders amounted to $8,925,000.

During  the nine  months,  573,900  shares of the  Company's  Common  Stock were
repurchased for $21,122,590 at an average discount from net asset value of 9.2%.

The market resumed its advance in the quarter just ended, led by  pharmaceutical
manufacturers  and companies that produce consumer  non-durable  goods like soft
drinks,  tobacco and  alcoholic  beverages.  On a more  selective  basis,  other
gainers included retailers and technology providers. Our portfolio lagged behind
the major  market  indices  owing to weakness in  commodity-based  securities  -
notably those related to the oil and natural gas industries.  It should be noted
that our exposure to this sector was markedly  reduced  earlier in the year,  as
reflected in the aforementioned net realized gains on securities sold.

It appears  that the economy is slowing and that the rate of earnings  growth is
likely to be tempered in the period immediately ahead. Personal spending,  which
has exceeded  income gains for some time, may falter as its enabler,  the rising
value of housing,  moderates or even reverses course.  Fiscal policy has been no
less generous, with government expenditure continuing to exceed tax receipts and
widening trade deficits conveying more and more wealth to foreigners. Stocks may
continue to perform well over the balance of the year, however, energized by the
tax-cut-like result of falling gasoline prices. Furthermore,  declining interest
rates could have a salubrious effect on price-to-earnings ratios, and facilitate
the refinancing of some mortgages that would otherwise burden consumer spending.

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  September  30,  2006.  It can be accessed  on the  internet at

9                  NOTES TO FINANCIAL STATEMENTS (Unaudited)
--------------------------------------------------------------------------------
                           General American Investors

1. SIGNIFICANT  ACCOUNTING  POLICIES - General American Investors Company,  Inc.
(the "Company"), established in 1927, is registered under the Investment Company
Act of 1940 as a closed-end,  diversified  management  investment company. It is
internally  managed  by  its  officers  under  the  direction  of the  Board  of
Directors.

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States  requires  management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

a. SECURITY VALUATION  Securities traded on a national  securities  exchange are
valued at the last reported  sales price on the last business day of the period.
Securities  reported on the NASDAQ  national  market are valued at the  official
closing price on that  day. Listed and NASDAQ  securities for which no sales are
reported on that day and other securities traded in the over-the-counter  market
are valued at the last bid price (asked price for open short  positions)  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.  Corporate
discount notes are valued at amortized cost,  which  approximates  market value.
Investments  in money market funds are valued at their net asset value.  Special
holdings  (restricted  securities) and other securities for which quotations are
not readily available are valued at fair value determined in good faith pursuant
to procedures  established by and under the general  supervision of the Board of
Directors.

b.  SHORT  SALES The  Company  may make  short  sales of  securities  for either
speculative or hedging purposes. When the Company makes a short sale, it borrows
the securities  sold short from a broker;  in addition,  the Company places cash
with that broker and securities in a segregated account with the custodian, both
as collateral for the short  position.  The Company may be required to pay a fee
to borrow the securities and may also be obligated to pay any dividends declared
on the  borrowed  securities.  The Company  will  realize a gain if the security
price decreases and a loss if the security price  increases  between the date of
the  short  sale  and the  date on  which  the  Company  replaces  the  borrowed
securities.

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  28,476,499
shares and 8,000,000  shares,  respectively,  were  outstanding at September 30,
2006.

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.
