New York Stock Exchange Dedicates Hall in Memory of Muriel F. Siebert, Its First Woman Member

NEW YORK & LOS ANGELES–(BUSINESS WIRE)–Siebert Financial Corp. (Nasdaq:SIEB) and Kennedy Cabot Acquisition, LLC
today announced the dedication of Siebert Hall at the New York Stock
Exchange (NYSE) in honor of the late Muriel F. “Mickie” Siebert, who
became the first woman to both own a seat on the NYSE and head one of
its member firms, Muriel Siebert & Co., Inc., on December 28, 1967.

Jane Macon, Chair of Siebert Financial Corp. said, “Mickie liked to say
that she came to New York City ‘with $500 and a used Studebaker.’ She
overcame tremendous challenges to become a legendary Wall Street
trailblazer, recognized as the ‘First Woman of Finance.’ We are
delighted Mickie’s contributions have been acknowledged by the NYSE in
such a historic way.”

The dedication of Siebert Hall is the first time a room at the NYSE,
designated a National Historic Landmark in 1978, has been named after an
individual.

Hosted by Tom Farley, NYSE Group President, the room features
memorabilia from Mickie Siebert’s career gifted to the NYSE by the
Estate of Muriel F. Siebert.

“When Mickie became the first female member of the NYSE in 1967, she
shattered a glass ceiling on Wall Street,” said Farley. “So, when it
came time to dedicate our newly-renovated meeting hall – a contemporary
counterpart to our more traditional Boardroom – the progressive and
ground-breaking Mickie was the obvious choice.” Gloria E. Gebbia, owner
and managing member of Kennedy Cabot Acquisition said, “Mickie Siebert
was courageous, savvy and pioneering, both as a woman and as a business
person. My family and I are proud and humbled to continue her
professional and charitable legacy. We believe she would be very pleased
that the Gebbia family shares her passion for worthwhile causes.”

Muriel Siebert, who died in 2013, was also a pioneer in the discount
brokerage field, transforming her firm into a discount brokerage in 1975
on the first day NYSE members were allowed to negotiate commissions. In
1977, she put her firm in a blind trust to serve as New York State’s
first woman Superintendent of Banking for five years, and under her
watch, not a single banking institution failed.

Throughout her career, Muriel Siebert was actively involved with a wide
range of non-profit, civic and women’s organizations. In keeping with
her personal vision, she worked tirelessly throughout her career to
promote financial literacy.

Among Muriel Siebert’s many achievements, through the Muriel F. Siebert
Foundation she focused on the development of the “Siebert
Personal Finance Program: Taking Control of Your Financial Future,”
a financial literacy program which has improved the lives of innumerable
middle and high school students and adults by teaching them essential
financial skills.

Muriel Siebert, who attended, but did not graduate from what is now
known as Case Western Reserve University in her home town of Cleveland,
Ohio, was awarded approximately twenty honorary doctorates and received
multiple other awards and honors throughout her life.

She was described by the Encyclopedia Britannica as an “American
business executive whose successful ventures in the realm of high
finance helped expand opportunities for women in that field.” Muriel
Siebert was chosen by Scholastic Inc., for its compendium, “100
People Who Changed America.” Other honors include the National
Association of Women Business Owners First Signature Award for Lifetime
Achievement as a pioneering women’s business owner; the National Museum
of Women in the Arts which saluted her as a pioneer who has broken
ground for women in civil society; and, acknowledgement from the Center
for Educational Innovation-Public Education Association (CEI-PEA) for
promoting financial literacy. Muriel Siebert was inducted into Junior
Achievement’s U.S. Business Hall of Fame in 2009 and is featured in the
“Women and Wall Street” permanent collection exhibit at the Museum of
American Finance.

As the first woman selected as “one who has made a difference” for the
Working Women’s Hall of Fame, she was inducted into the National Women’s
Hall of Fame and The International Women’s Forum International Hall of
Fame. Muriel Siebert received The Athena Foundation’s highest award
given to those “who open the doors of leadership opportunity for women.”
Among other honors, she received the Pride of New York Award, and, for
championing financial literacy, both the First Lifetime Achievement
Award from the New Jersey Coalition for Financial Education and the
Eleanor Roosevelt Val-Kill Medal Award.

Muriel Siebert was widely interviewed on subjects pertaining to the
financial system and markets. She testified on behalf of individual
investors before Congress and her opinion was requested by the White
House and policymakers at the highest levels of the US government on
many substantive issues related to the financial services system and
economy.

In November 2002, Simon and Schuster published her autobiography, Changing
the Rules – Adventures of a Wall Street Maverick.
