Subscription Rights financial
"received one subscription right (the "Rights") for each share of Common Stock"
Subscription rights are short-term privileges given to existing shareholders to buy additional new shares before the general public, typically at a set price and in proportion to their current holdings. Think of it as getting a coupon for first dibs on extra slices of a pizza so your share of the pie doesn’t shrink; exercising them can be a cheaper way to maintain your ownership and voting power, while ignoring them can reduce your stake and potential future earnings.
Over-Subscription Privilege financial
"additional shares of Common Stock at the subscription price if other Rightsholders did not fully exercise their Rights"
An over-subscription privilege is a feature of a share offering that lets existing investors request more shares than their initial entitlement, with any extra allocation given only if other investors do not take their full allotment. It matters because it gives shareholders a chance to increase their stake and avoid losing ownership percentage, much like ordering extra slices at a party in case others pass—however, receiving the extras is not guaranteed.
