advanced design maturity, and affordable within available funding. We achieved the goal of a strong LLP package in less than a year after IRA funding became available, a major accomplishment benefiting the entire project.</span><span style="color:#212121"><o:p></o:p></span></p>

<span style="font-size:12.0pt;color:#212121">Funding Uncertainties – The annual funding profile for the EIC project will remain uncertain until we secure CD-2. Our job is to continue to make the maximum technical progress with the funding available and to
prepare the EIC performance baseline for DOE approval. The IRA funding was a game changer, providing a needed boost, but in general, we can expect our progress will be funding-limited until we secure an approved baseline. There is important progress on securing
the $100M in New York State funding committed to the construction of EIC buildings. The agreement was recently submitted to DOE for approval.</span><span style="color:#212121"><o:p></o:p></span></p>
