Siebert Williams Shank Hires Allan Katz as Chief Financial Officer




New York, NY — Siebert Williams Shank & Co. (SWS) announces a key new hire in Allan M. Katz, most recently Chief Financial Officer of Guggenheim Securities. Katz has been named CFO at SWS, further positioning the firm for a new phase of growth in 2024.


Katz is a transformational CFO known for guiding operational improvement and expense control in the financial services sector. As CFO of Guggenheim Securities, a FINRA-regulated broker-dealer, Katz spent the last 10 years elevating the finance function in a period of significant growth in revenue, EBITDA, and overall headcount.


Katz will be tasked with managing and contributing to Siebert Williams Shank’s strong financial reporting and control environment. Based in the firm’s Wall Street office, he expects to be a strategic partner to the executive management team focused on business strategy and growth, and to positively contribute to the strong partnerships and client service for which the firm is known.


A Series 27 Operating Principal, Katz has skillfully leveraged technology to automate manually intensive processes and provide immediate access to trading desk-level financial results. He led Guggenheim Securities’ strategic planning and business review processes and was part of the decision-making team that acquired a European-based broker-dealer to obtain licensing for business expansion.


Katz joined Guggenheim from Citigroup, where, as Managing Director, Expense Management and Services, he facilitated efficiencies across the firm’s infrastructure and corporate functions. Earlier, he spearheaded the global planning process for Nomura Holding America, with significant travel to Japan, London, and Mumbai. He also led the transition services team responsible for negotiating infrastructure services and guiding the disposition of assets after the collapse of Lehman Brothers.


Katz, who earned an MBA in Finance and International Business from the Stern School of Business at New York University and a BS in Accounting from Binghamton University, began his career in the Middle Markets Practice at Coopers & Lybrand before moving on to accounting and finance roles at J.P. Morgan & Co. and Mercer Management Consulting. He also held Planning & Analysis roles at Merrill Lynch for 10 years.


A longtime participant and advocate for nonprofit groups, he has been involved with the Pancreatic Cancer Action Network, PENCIL (New York City Principal for a Day program), and Junior Achievement. He was a member of Guggenheim’s Corporate Social Responsibility Committee and participated in several Guggenheim-sponsored mentoring programs.
