The following pages discuss the nature of AWM Investment Company’s investment advisory
business and introduce its principal owners and other pertinent personnel.
General Description of Advisory Firm
AWM Investment Company, Inc. (“AWM”) is a registered investment adviser with the SEC
under the Investment Adviser Act of 1940. AWM has been in business since 1992 and is a
Delaware corporation. AWM has 15 employees, and is headquartered in New York, NY.
Assets Under Management
As of January 1, 2024, AWM’s assets under management totaled $867,554,097. We have
complete discretionary authority over AWM Fund assets, and we do not serve as investment
advisor to any other accounts, discretionary or otherwise.
Description of Advisory Services
Our firm offers investment advice primarily in equity securities and securities with equity
features of publicly traded companies that possess a technological, market, or product niche,
which may be for various reasons, undervalued, or with prospects of going private or being
acquired. The Funds consider such types of investments to be “special situation investments.”
We tailor our investment advice to eight private investment funds (collectively, the “Funds”) for
which we serve as investment adviser. These Funds are: Special Situations Fund III QP, L.P.
(“SSFQP”), Special Situations Cayman Fund, L.P. and its feeder fund, Special Situations
International, Ltd. (collectively, the “Cayman Fund”), Special Situations Private Equity Fund,
L.P. (“Private Equity Fund”), Special Situations Technology Fund, L.P. (“Tech Fund”), Special
Situations Technology Fund II, L.P. (“Tech Fund II”), (together referred to as the “Tech Funds”),
Special Situations Life Sciences Fund, L.P. (“Life Sciences Fund”), Life Sciences Innovation
Fund, L.P. (“Innovation Fund”), and Life Sciences Innovation Fund II, L.P. (“Innovation Fund
II”) (together referred to as the “Innovation Funds”). Additionally, AWM serves as the general
partner of MGP Advisers Limited Partnership (“MGP”), the general partner of SSFQP.
When making investment decisions on behalf of any one Fund we consider that Fund’s unique
investment objective. Two of the Funds, SSFQP and the Cayman Fund, seek to maximize
capital appreciation through general analysis of equity and equity-related securities, while the
Tech Funds focus primarily on publicly traded companies that provide products and services in
the communications, information, and other technology-related fields. The Life Sciences Fund
invests primarily in publicly traded equity of companies that provide products and services in
health care, life sciences, and related fields. The Private Equity Fund invests primarily in
privately negotiated and privately placed equity and equity-related securities of publicly traded
companies which possess a technological, market or product niche. The Innovation Fund invests
in various seed, early and developmental stage private companies in the assisted reproductive
technology sector. The Innovation Fund II was formed as a follow-on Fund of the Innovation
Fund to make follow-on investments in the portfolio companies of the Innovation Fund.
AWM also provides certain administrative duties to each of the Funds discussed above. As such,
we provide the office space, facilities and personnel that are necessary to provide these
administrative services required for the operation of the business and affairs of the Funds.
