Stem Board of Directors Appoints CEO Arun Narayanan to Board

Key Terms

adjusted EBITDA financial

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Class I Director regulatory

A class I director is a member of a company’s board who belongs to one of several groups whose terms expire in a specified year under a staggered election system; each class is elected on a different cycle so only a portion of the board faces re-election each year. This matters to investors because it affects how quickly control of the board can change, the company’s continuity and oversight, and the ease of mounting or defending against takeover efforts—think of a team where only some players are replaced each season rather than the whole roster at once.

shelf registration statement regulatory

A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.

Form S-3 regulatory

Form S-3 is a legal document companies use to register their stock sales with the government, making it easier and faster for them to raise money by selling shares to investors. It’s like having a pre-approved shopping list that lets a company quickly sell new shares when they need funds, without going through a lengthy approval process each time.
