**Stuart Jason Zimmer** is a seasoned investment professional with over 30 years of experience in the asset management industry, currently serving as the Founder, Chief Executive Officer, and Portfolio Manager of Zimmer Partners LP, a New York-based, research-driven investment firm specializing in the energy and infrastructure sectors. He also serves as Chief Executive Officer of ZFSG, an insurance and asset management entity. Zimmer began his career as a research analyst at Steinhardt Partners before co-founding and serving as a Partner at Zimmer Lucas Capital. He subsequently founded Zimmer Partners LP, where he has built a reputation as a specialist investor focused on the energy value chain. His portfolio investments, as tracked by CB Insights, span companies including CarGurus (NASDAQ: CARG), SparkCharge, Snowflake Computing (NYSE: SNOW), AOL, Talent Neuron, and Theta Labs, reflecting a broad technology and growth-oriented investment mandate alongside his core energy and infrastructure focus.
In the SPAC arena, Zimmer served as Chairman of the Board and Chief Executive Officer of Zimmer Energy Transition Acquisition Corp., a blank check company incorporated in 2021 and headquartered in New York. The SPAC was formed to target the energy transition and sustainability space in North America, with a primary focus on products, equipment, services, and technologies enabling the continued energy transition in the United States. The company priced its IPO on June 16, 2021, raising $345 million through the offering of 34,500,000 units at $10.00 per unit, with each unit consisting of one share of common stock and one-third of a warrant exercisable at $11.50. The deal was originally filed to raise $350 million before terms were lowered. Zimmer Partners intended to purchase $100 million worth of units in the offering, representing 33% of the deal, and the company had forward purchase agreements with Zimmer Partners and Bluescape Resources for an additional $200 million at the closing of an acquisition. Citi and Barclays acted as joint bookrunners, and the units traded on the Nasdaq under the symbol ZTAQU. Zimmer personally purchased 3,500,000 shares at $10.00 per share in June 2021, a $35 million commitment. The SPAC ultimately did not complete a business combination; it announced the redemption of public shares and subsequent dissolution, with trading suspended effective June 16, 2023, and a closing/liquidation date of June 16, 2023, exactly 24 months after its IPO.
Zimmer graduated from Harvard College with a degree in mathematics, a member of the class of 1991. He and his wife Jennifer conduct their philanthropy through the Zimmer Family Foundation, which awarded approximately $1.52 million in grants in 2018, with a strong focus on Jewish causes, education and youth, and health, primarily in the Northeast. Zimmer is the founding donor of Zimmer Preschool, a Chabad school in Basking Ridge, New Jersey, and the family supports organizations including Friends of IR David, Temple Israel, Congregation Beth Sholom, Solomon Schechter Day School of Bergen County, Columbia University, and the Overtown Youth Center in Miami. The couple is also involved with the Halachic Organ Donor Society, a cause with personal significance as Zimmer is a kidney transplant recipient. The Zimmer family resides in the New York area, and their children Zachary and Sabre have followed their father to Harvard.
This record is keyed to SEC CIK 0001858477 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 22 institutional-holder rows on these vehicles, under 17 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
