The teachers use the results to help them make their assessments. They report their own assessments at the end of the year based on level criteria. The teacher will have been tracking levels and progress throughout the year.
Parents rarely (if ever) see the results of the tests. Many schools have tested already without parents even knowing about it. It's no big deal.

By law schools MUST give parents their child's KS1 SATs results (as reported to the LEA) - www.education.gov.uk/sta/keystage1/a00222273/ks1-templates
The timing for reporting this data gathered on your child at taxpayer's expense is flexible - but basically has to occur by the time of the end of year report.
ipadquietly is correct - schools can have children sit KS1 SATs papaers at any point (I believe results are entirely teacher assessed - so not externally marked, although they may be moderated by the LEA, and can also take into account child's overall performance not just the formal sit down test).
------
More generally the point of KS1 SATs is at present this is the first formal assessment of your child's ability and these results and is used as a predictor of expected performance at end KS2 (Y6).
Schools are expected to make two full NC Levels improvement on the score in KS1 SATs. So scoring NC L2 (expected progress) at end KS1 would have your child expected to achieve NC L4 at end of KS2 SATs exams. A school who supports a child to make more than expected progress over KS2 would mean the child would have to achieve NC L5 at KS2 SATs.
For the uninitiated: MN has a discussion of what NC Levels mean here: www.mumsnet.com/learning/assessment/what-national-curriculum-levels-mean and how your child should progress through NC Levels here: www.mumsnet.com/learning/assessment/progress-through-national-curriculum-levels
However NC Levels are soon to be abandoned (one of Gove's new initiatives) and how schools assess progress will be devolved down to individual schools. So be prepared for your child is 3 unicorns + a golden starburst dear parent - you should be very pleased! ... with absolutely no indication of what that might mean against National curriculum targets.
I suspect NC Levels weren't meaningless - the issue was the parents were finally getting the hang of them. However, it is interesting to track KS2 SATs performance over time (www.theguardian.com/news/datablog/2013/sep/19/sats-results-key-stage-two - see tables at the bottom and look at increase % of L5 results over time) - there clearly is a sharp increase in NC L5 performance - yet I can assure you Universities are finding pupils less prepared for rigours of academic writing/ research.
