  We show that `Oumuamua's excited spin could be in a high energy LAM state,
which implies that its shape could be far from the highly elongated shape found
in previous studies. CLEAN and ANOVA algorithms are used to analyze `Oumuamua's
lightcurve using 818 observations over 29.3~days. Two fundamental periodicities
are found at frequencies (2.77$\pm$0.11) and (6.42$\pm$0.18)~cycles/day,
corresponding to (8.67$\pm$0.34)~h and (3.74$\pm$0.11)~h, respectively. The
phased data show that the lightcurve does not repeat in a simple manner, but
approximately shows a double minimum at 2.77~cycles/day and a single minimum at
6.42~cycles/day. This is characteristic of an excited spin state. `Oumuamua
could be spinning in either the long (LAM) or short (SAM) axis mode. For both,
the long axis precesses around the total angular momentum vector with an
average period of (8.67$\pm$0.34)~h. For the three LAMs we have found, the
possible rotation periods around the long axis are 6.58, 13.15, or 54.48~h,
with 54.48~h being the most likely. `Oumuamua may also be nutating with
respective periods of half of these values. We have also found two possible SAM
states where `Oumuamua oscillates around the long axis with possible periods at
13.15 and 54.48~h, the latter as the most likely. In this case any nutation
will occur with the same periods. Determination of the spin state, the
amplitude of the nutation, the direction of the TAMV, and the average total
spin period may be possible with a direct model fit to the lightcurve. We find
that `Oumuamua is "cigar-shaped"', if close to its lowest rotational energy,
and an extremely oblate spheroid if close to its highest energy state for its
total angular momentum.
