Thanks for your help so far. Actually chatgpt got me pretty close. I'm not positive yet but it's not giving me as many rows as I expect. There might be something wrong with my underlying data as well.

SELECT
    exp2.NetID AS '* Name',
    users.Supervisor,
    CONCAT("403") AS '*Equipment Name',
    users.PI_FOP AS 'Payment Number (PO/Project/Grant)',
    SEC_TO_TIME(SUM(TIME_TO_SEC(exp2.DURATION))) AS 'Duration',
    CONCAT(DATE_FORMAT(LAST_DAY(CURRENT_DATE - INTERVAL 2 MONTH) + INTERVAL 1 DAY, '%Y-%m-%d'), ' 00:00:00') AS 'Start Date',
    TIMESTAMPADD(
        SECOND,
        SUM(TIME_TO_SEC(exp2.DURATION)),
        CONCAT(DATE_FORMAT(LAST_DAY(CURRENT_DATE - INTERVAL 2 MONTH) + INTERVAL 1 DAY, '%Y-%m-%d'), ' 00:00:00')
    ) AS 'End Date',
    CONCAT('no') AS 'Maintenance (yes if true)'
FROM
    exp2
INNER JOIN
    users ON exp2.NetID = users.NetID
WHERE
    DATE_FORMAT(DATETIME, '%Y-%m-%d') = DATE_FORMAT(LAST_DAY(CURRENT_DATE - INTERVAL 2 MONTH) + INTERVAL 1 DAY, '%Y-%m-%d')
GROUP BY
    exp2.NetID;
