Nelnet, Inc

A borrower sees a monthly student-loan bill, but the amount on that bill depends on a policy regime, a servicing platform, a call center, payment rails, identity controls and years of political change all working at once. Nelnet, Inc. sits in the middle of that operating chain: valuable when it can turn public-program volatility into reliable borrower administration, exposed when policy shocks turn into queues, complaints, contract penalties or trust loss.
