Claire McAdams brings over three decades of capital formation experience, with a focus on the semiconductor, capital equipment, and advanced manufacturing sectors. Acting as an embedded deal execution specialist within executive leadership teams or as an investment banker, Claire has led, executed or supported over 40 successfully completed financings across the full spectrum of capital formation options – from private equity placements for mid- to later-stage private companies, to IPOs (both in the U.S. and Asia), to follow-on offerings of primary/secondary shares (including confidentially marketed overnights, ATMs, ADRs, and other structures), as well as experience with a multitude of debt alternatives.
Claire’s financing expertise also spans the complete capital formation life cycle, from accretion/dilution scenario modeling for the board of directors – to deal origination, strategy, and execution (including assembling the deal team and setting deal economics) – to strategic financial communications (IR messaging and shareholder engagement).
Headgate Partners understands the operational, financial, and governance complexities that underpin successful financing outcomes. As a former investment banker herself, Claire is a seasoned consumer of investment banking services, enabling her to add significant value for her companies by orchestrating the most cost-effective and optimized execution teams for her companies. Claire’s work on financings is defined by sector expertise, strategic clarity, executional discipline, and long-term value creation — made all the more effective by removing the incentive of a “success fee” … now having completed the majority of her financings as an integral member of company management teams.
