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

Dear Shareholders,

We at The Needham Funds, Inc. focus on buying growth stocks at reasonable
prices. In the volatile six-month period we have just experienced, we are
pleased that each of the funds was in positive territory for our investors.
During the six months ended June 30, 2004, the Growth Fund appreciated 3.10%,
the Aggressive Growth Fund appreciated 2.69% and the Small Cap Growth Fund
appreciated 7.01%. By comparison, the S&P 500 Index appreciated 3.44%, the
NASDAQ Composite Index appreciated 2.43% and the Russell 2000 Index appreciated
6.80%. Since June 30, the S&P 500 Index is down 6.61%, the NASDAQ Composite
Index is down 14.38% and the Russell 2000 Index is down 12.47% through August
12. The Funds' performance has suffered accordingly.

The Needham Growth Fund (the "Growth Fund") seeks to create long-term,
tax-efficient capital appreciation for its investors. To this end, the Growth
Fund targets companies with products or services that are selling or marketing
into growth markets. These companies normally have earnings growth of at least
15-20%, product and market dominance, and the ability to consolidate their
market positions. They may also have a competitive advantage by acquiring and
retaining more customers or driving costs down and profits up. The Growth Fund
also looks for seasoned and motivated managements with records of building
shareholder value. Companies with these characteristics sometimes find
themselves in a temporary earnings downturn or shortfall or may be in a product
transition. This often causes aggressive growth or dynamic growth investors to
sell. At this point, the Growth Fund may deem the stock to be reasonably priced
and purchase it for long-term capital appreciation. Hence, the discipline called
"Growth At a Reasonable Price," or "GARP."

The Growth Fund's performance for the six-month period was in line with the rest
of the markets. However, we are not satisfied with a 3.10% return. Our cash
(3.52%) and short positions (7.91%) were not enough to offset the pressure on
our long portfolio. One of our key sectors, technology, was not treated well in
these markets. Our concentration in technology at 42.79% is high, and we are
continuing to reduce this sector throughout 2004 but only on a targeted basis.
Our best performing stocks were Ceradyne, Inc., Motorola, Inc., Harris Corp. and
Scientific-Atlanta, Inc.

The Needham Aggressive Growth Fund (the "Aggressive Growth Fund") seeks to
create long-term, tax-efficient capital appreciation for its investors. To this
end, the Aggressive Growth Fund targets the equities of companies with strong,
above-average prospective growth rates. The Aggressive Growth Fund invests, in
general, in markets and industries with strong growth rates, focusing on the
market leaders in these areas. These market leaders, especially as they break
away from their competitors, tend to garner a disproportionate share of the
positive financial returns. Also important is the long-term sustainability of
the companies' leadership positions. Thus, the Aggressive Growth Fund looks for
companies with strong management teams, superior balance sheets, above-average
margins that can generate excess cash, and strong R&D and brand spending in
industries with high barriers to entry.

The Aggressive Growth Fund's performance was affected by our hedging and
shorting, which was a negative factor. The healthcare, consumer and business
services segments were the strongest for the Aggressive Growth Fund over the
past six months. The technology sector produced mixed results, and the media
sector had a small negative contribution. The Aggressive Growth Fund
particularly benefited from Biogen Idec, Inc., Rogers Corp., Autodesk, Inc. and
Hyperion Solutions Corp.

                                                                               1


Needham Funds
- --------------------------------------------------------------------------------

The Needham Small Cap Growth Fund (the "Small Cap Growth Fund") seeks long-term,
tax-efficient capital appreciation by investing primarily in equity securities
of smaller growth companies that the Small Cap Growth Fund believes are trading
at a discount to their underlying value yet have the potential for superior
long-term growth. Under normal conditions, the Small Cap Growth Fund invests at
least 80% of its total assets in equity securities of domestic issuers that have
market capitalizations of $2 billion or less and that are listed on a nationally
recognized securities exchange or traded on the NASDAQ system. Central to the
Small Cap Growth Fund's investment strategy is a sound valuation discipline that
seeks to acquire growth companies at reasonable prices. The Small Cap Growth
Fund seeks tax efficiency by holding securities for a period of 12 months or
more to obtain long-term capital gain treatment and by offsetting capital gains
on the sale of securities with capital losses.

We were able to do better in the second quarter than the first, mainly due to a
rally at the end of June. We had reduced the short position down to 1.25% and
cash ended at 13.36%. The long positions of the Small Cap Growth Fund are
balanced appropriately in four sectors of our expertise. The Small Cap Growth
Fund benefited from several good performers: Eon Labs, Inc., First Horizon
Pharmaceutical, Bright Horizons Family Solutions and Ceradyne, Inc.

The portfolio turnover rate was 17.79% for the Growth Fund, 60.64% for the
Aggressive Growth Fund and 63.45% for the Small Cap Growth Fund for the six
months ended June 30, 2004. The expense ratios for the three funds were 1.74%
for the Growth Fund, 2.50% for the Aggressive Growth Fund and 2.50% for the
Small Cap Growth Fund for the six months ended June 30, 2004.

We think that the current economic trends still favor an up stock market in 2004
but the road is looking increasingly bumpy, given high equity valuations, the
presidential race, ballooning trade and fiscal budget deficits, and continued
political and military uncertainty in Iraq. One improving trend in the last four
months has been U.S. job growth, but the market appears to be focused on the
negatives and the summer doldrums have not helped. With that said, we are
hopeful that there will be a bounce either before or right after the elections
when investors realize that we have survived far worse market conditions and,
whether the press accepts it or not, corporate America is continuing to grow at
a modest but sustainable rate, which should bode well for the rest of 2004 and
beyond.

Sincerely,

    The table above does not reflect the deduction of taxes that a shareholder
would have paid on Fund distributions or on the redemption of Fund shares.
Investment results and the principal value of an investment will vary. Past
performance noted above does not guarantee future results. When shares are
redeemed, they may be worth more or less than their original cost. Since
inception, the Fund's Adviser has absorbed certain expenses of the Fund, without
which returns would have been lower.

                                                                               5

Notes to Financial Statements (Unaudited)

1. ORGANIZATION

Needham Growth Fund ("NGF"), Needham Aggressive Growth Fund ("NAGF") and Needham
Small Cap Growth Fund ("NSCGF") or (the "Portfolios"), are portfolios of The
Needham Funds, Inc. (the "Fund"), which is registered under the Investment
Company Act of 1940 as a non-diversified, open-end management investment
company. The Fund was organized as a Maryland corporation on October 12, 1995.

2. SIGNIFICANT ACCOUNTING POLICIES

Security Valuation: Investments in securities (including options) listed or
traded on a nationally recognized securities exchange are valued at the last
quoted sales price on the date the valuations are made. Portfolio securities and
options positions for which market quotations are readily available are stated
at the Nasdaq Official Closing Price or the last sale price reported by the
principal exchange for each such security as of the exchange's close of
business, as applicable. Securities and options for which no sale has taken
place during the day and securities which are not listed on an exchange are
valued at the mean of the current closing bid and asked prices. All other
securities and assets for which market quotations are not readily available are
valued at their fair value as determined in good faith by the Board of
Directors, although the actual calculations may be made by persons acting
pursuant to the direction of the Board of Directors. The assets of each
Portfolio may also be valued on the basis of valuations provided by a pricing
service approved by, or on behalf of, the Board of Directors.

Other: Security transactions are accounted for on the date the securities are
purchased or sold. The cost (proceeds) of investments sold (bought to cover) is
determined on a specific identification basis for the purpose of determining
gains or losses on sales and buys to cover short positions. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. Interest
income is recorded on an accrual basis.

Use of Estimates: The preparation of financial statements in accordance with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates and those differences could be material.

3. INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES

The Fund has engaged Needham Investment Management L.L.C. (the "Adviser") to
manage its investments. The Fund pays the Adviser a fee at the annual rate of
1.25% of the average daily net asset value of each Portfolio.

The Adviser has voluntarily agreed to waive its fee for, and to reimburse
expenses of, each Portfolio in an amount that limits annual operating expenses
for each Portfolio for the six months ended June 30, 2004 to not more than 2.50%
of average daily net assets of each Portfolio. For the six months ended June 30,
2004, the Adviser waived advisory fees in the amount of $39,747 and $7,255 for
NAGF and NSCGF, respectively. The Adviser waived none of its fees for NGF during
the six months ended June 30, 2004.

PFPC Inc. ("PFPC") acts as the Fund's Administrator. The Fund pays PFPC a fee at
the annual rate of 0.10% of the average daily net asset value of each Portfolio,
subject to certain minimums. PFPC also acts as the Fund's shareholder servicing
agent and transfer agent.

Certain officers and directors of the Fund are also officers and directors of
the Adviser.

4. FEDERAL INCOME TAXES

No provision for federal income taxes is required since the Fund intends to
continue to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute substantially all of its taxable income and
capital gains to shareholders. Because income tax regulations differ from
generally accepted accounting principles, the timing and character of income and
capital gain distributions determined in accordance with tax regulations can
differ from income and capital gains recognized for financial reporting
purposes. Accordingly, the character of distributions and the composition of net
assets for tax purposes can differ from those reflected in the financial
statements. These book/tax differences may be temporary or permanent in nature.
To the extent these differences are permanent, they are charged or credited to
paid-in capital, accumulated net realized gain (loss) or accumulated net
investment income (loss), as appropriate, in the period the differences arise.
These reclassifications have no effect on net assets or net asset value per
share of each Portfolio.

As of June 30, 2004, the components of distributable earnings (loss) on a tax
basis were as follows:

5. TEMPORARY BORROWINGS

The Fund has entered into an agreement with the Custodial Trust Company for
temporary borrowing purposes, including the meeting of redemption requests that
otherwise might require the untimely disposition of securities. Interest is
calculated daily based on the Federal Funds Rate plus one percent. The Fund may
borrow from banks up to 25% of its total assets and may pledge its assets in
connection with these borrowings, provided that no additional investments shall
be made while borrowings exceed 5% of total assets. During the six months ended
June 30, 2004, borrowings were as follows:

6. DISTRIBUTION PLAN

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plan, each Portfolio pays Needham &
Company, Inc. and any other distributor or financial institution with which the
Fund has an agreement with respect to each Portfolio, a fee at an annual rate of
0.25 of 1% of each Portfolio's daily average net assets. For the six months

8. OPTION TRANSACTIONS

The Fund may invest in options contracts to reduce the Portfolios' exposure to
fluctuations in the prices of portfolio securities and to prevent losses if the
prices of such securities decline. Similarly, such investments may protect the
Portfolios against fluctuations in the value of securities in which the
Portfolios are about to invest.

The Portfolios may write call and put options on securities they own or have the
right to acquire, and may purchase put and call options on individual securities
and indices written by others. Put and call options give the holder the right to
sell or purchase, respectively, a specified amount of a security at a specified
price on a certain date.

The Portfolios are subject to market risk associated with changes in the value
of the underlying financial instrument, as well as the risk of loss of
appreciation if a counterparty fails to perform. For exchange-traded contracts,
the exchange acts as the counterparty to specific transactions, and there-

                                                                              23

fore, bears the risk of delivery to and from counterparties of specific
positions.

Put and call options purchased are accounted for in the same manner as portfolio
securities. The cost of securities acquired through the exercise of call options
is increased by the premium paid. The proceeds from securities sold through the
exercise of put options are decreased by the premiums paid. Options on stock
indices differ from options on securities in that the exercise of an option on a
stock index does not involve delivery of the actual underlying security and is
settled in cash only.

When a Portfolio writes an option, the premium received by the Portfolio is
recorded as a liability and is subsequently adjusted to the current market value
of the option written. Premiums received from writing options which have expired
are recorded by the Portfolio on the expiration date as realized gains from
option transactions. When a Portfolio enters into a closing purchase
transaction, the Portfolio realizes a gain or loss equal to the difference
between the cost of a closing purchase transaction and the premium received when
the option was written. If a written call option is exercised, the premium
received is added to the proceeds from the sale of the underlying security in
determining whether the Portfolio has a realized gain or loss. If a written put
option is exercised, the premium received reduces the cost basis of the
securities purchased. In writing an option, the Portfolio bears the market risk
of an unfavorable change in the price of the security underlying the written
option.

A summary of options written by NGF for the six months ended June 30, 2004 is as
follows:

</Table>

In the normal course of business, certain of the Portfolios will trade and hold
certain fair-valued derivative contracts which constitute guarantees under
Financial Accounting Standards Board Interpretation 45. Such contracts include
written options where the Portfolios would be obligated to purchase or sell a
specified security at a specified price if the option is exercised by the
counterparty. The maximum payouts for these contracts are limited to the number
of contracts written and the related strike price. The maximum payout amount
could be offset by the subsequent sale of assets obtained via the execution of a
payout event.

Neither NAGF nor NSCGF had purchased or written options during the six months
ended June 30, 2004.

9. SHORT SALE TRANSACTIONS

During the six months ended June 30, 2004, the Portfolios sold securities short.
Upon selling a security short, the Portfolios record a receivable for the
settlement amount and a corresponding liability, which is marked-to-market to
reflect current value. Securities owned by the Portfolios are segregated as
collateral while the short sales are outstanding. At June 30, 2004, the market
value of securities separately segregated to cover short positions was
approximately $64,978,000, $4,354,000 and $776,000 for NGF, NAGF and NSCGF,
respectively. Securities sold short at June 30, 2004 and their related market
values and proceeds are set forth in the accompanying Schedules of Securities
Sold Short.

10. FINANCIAL INSTRUMENTS

The Fund has always maintained a policy of valuing its securities positions and
derivative instruments at market values or estimated fair values and of
including any realized or unrealized gains or losses in income.

In the normal course of its business, the Portfolios may trade various financial
instruments with off-balance sheet risk. These financial instruments include
securities sold short and exchange traded options. Generally, these financial
instruments represent future commitments to purchase or sell other financial
instruments at specific terms at specified future dates. Each of these financial
instruments contains varying degrees of off-balance sheet risk whereby changes
in the market values of the securities underlying the financial instruments may
be in excess of the amounts recognized in the financial statements.

Securities sold short represent obligations of the Portfolios to make future
delivery of specific securities and, correspondingly, create an obligation to
purchase the securities at market prices prevailing at a later delivery date (or
to deliver the securities if already owned by the Portfolios). As a result,
short sales create the risk that the Portfolios' ultimate obligation to satisfy
the delivery requirements may exceed the amount of the proceeds initially
received on the liability recorded in the financial statements.
