Exhibit 99.1

1 July 2021

ABCAM PLC

Result of General Meeting

Abcam plc (AIM: ABC; NASDAQ: ABCM), a global leader in the supply of life science research tools, announces that all resolutions put to its General Meeting (the “General Meeting”) held this afternoon were passed.

The Board is pleased that all resolutions have been approved by shareholders and notes that a minority of shareholders opposed Resolutions 1 and 2 (to approve a new Remuneration Policy and adopt a new Profitable Growth Incentive Plan (“PGIP”)).

Prior to today’s meeting, Abcam’s Remuneration Committee received positive indications of support for the final proposals following an extensive consultation process. The Committee recognises that a proportion of shareholders (including those who follow the guidance of their proxy advisors) were not able to support the new Remuneration Policy or the new PGIP.

The Remuneration Committee acknowledges concerns raised by shareholders in their voting but believes it is important to emphasise that throughout its discussions there was support from shareholders for the over-arching objectives of the plan to align long-term incentives with the delivery of the 2024 Strategy, and the plan itself. There was also broad recognition that, as an increasingly global business, to sustain its future success Abcam must be able to effectively compete for and retain talent in a global marketplace, in particular when competing against US listed life science and healthcare companies.

The approved PGIP is an important step forward towards aligning incentives to Abcam’s growth plans for over 80 senior leaders in the business.

Abcam has not applied for any Government funded wage subsidies or furlough arrangements related to the Covid pandemic. Rather, it has implemented two company-wide pay increases since March 2020.

The Board remains firmly committed to maintaining an open dialogue with its shareholders to ensure it fully understands their views and it will continue to constructively engage with those shareholders who were unable to support the proposals.
