What happened
Schrodinger, Inc. (NASDAQ: SDGR) executive Yvonne Tran sold 32,000 shares on Nov. 9 for about $1.05 million. All of the shares came from options exercised the same day. The Form 4 says the trades followed a Rule 10b5-1 plan that Tran, the company's EVP, CLO and CPO, adopted on Aug. 10.
The options had a $17 exercise price. They were granted on Feb. 5, 2020, are fully vested and expire on Feb. 5, 2030. Tran sold the shares in four blocks of 400, 2,100, 7,901 and 21,599 shares. Weighted average prices rose from $29.97 in the smallest block to $33.11 in the largest. Individual sales ranged from $29.74 to $33.66.
After the sales, Tran held 52,683 shares, including 42,191 unvested restricted stock units. Tran also holds 156,619 stock options.

Why it matters
The sale is large against what Tran held. By OptimistFi's calculation, the shares sold were 37.8% of the 84,683 shares Tran held after exercising the options and before selling.
The sale matched the exercise share for share, so Tran's share count ended where it stood before the exercise. The filing also checks the box showing the plan is meant to meet the conditions of Rule 10b5-1(c), so the sale was arranged in advance.
The size of the trade stands out. But the filing ties it to a preset plan and a same-day option exercise, so the sale says little about the business. The plan was adopted on Aug. 10 and the sales were reported for Nov. 9, so the trades followed a schedule set earlier.
OptimistFi has argued that Schrodinger's value rests on platform adoption and new product launches scaling while restructuring cost discipline holds. One officer's planned sale leaves that case unchanged.

What's next
The next test is Schrodinger's next quarterly report. Growth in platform adoption and product launches with steady costs would support the case. Slippage in either would weaken it.
