As announced in the press release issued by Lantheus Holdings, Inc. (the “Company”) on April 9, 2020, the COVID-19 pandemic has impacted demand for the Company’s products, as hospitals are focusing on life threatening situations rather than some of the elective procedures in which the Company’s products are used. As a result, the Company is implementing certain proactive cost cutting measures. As part of those measures, effective April 13, 2020 through June 30, 2020, the Company is implementing a four day work week to better align manufacturing, supply, distribution and other activities with reduced product demand, and the Company is implementing a corresponding reduction in pay to its personnel. In particular, the Company’s President and Chief Executive Officer, Mary Anne Heino, has agreed to reduce her base salary by 75% during that period, and each of the Company’s other named executive officers has agreed to reduce his base salary by 35% during that period. The Company has also made across-the-board reductions of 20% to 35% (depending on level of position) of salaries for other salaried employees and a reduction of 20% of hours for hourly employees, in each case, to reflect the reduced workload expected during that period. These measures will be reevaluated at the end of that period.

In addition, the Company’s Board of Directors has also reduced director and committee member compensation by 35% during this period and has elected to receive all remaining compensation payable in 2020 in the form of time-based restricted stock units that will vest on the first anniversary of the grant date, rather than in cash. These restricted stock units will be granted quarterly as compensation is earned.
