Buchholz Richard Buy
1,000 shares
$14,840
@ $14.84
Significance 4/10

Director Buchholz buys 1.0K shares of SI at $14.84; holds 13.7K post-transaction. Company unprofitable but revenue up 49.6% YoY.

Buchholz purchased 1,000 shares at $14.84 on 2026-03-13, increasing his holdings to 13.7K shares (a +7.9% increase). The company is currently unprofitable with net income of $-8.7M against revenue of $11.8M, though annual revenue growth was +49.6%. Buchholz's prior buy at this same ticker on 2025-08-01 returned -20.7% over 90 days, establishing a pattern of poorly-timed purchases at SI; this new buy occurs as the stock trades at -7.8% from its 52-week high despite a +15.8% 30-day gain. The presence of 2 other insider buys within 14 days suggests coordinated director-level interest, though Buchholz's prior trading history at this ticker does not support confidence in the timing.

Significance 4/10

CFO Jeffrey S. bought 2,000 shares of SI at $15.00; company unprofitable but shows +49.6% revenue growth and cluster buy pattern

Jeffrey S., Chief Financial Officer of Shoulder Innovations, purchased 2,000 shares at $15.00 on 2026-03-13, bringing his holdings to 70,785 shares. The company reported a net loss of $-8.7M on revenue of $11.8M in its latest quarter, though full-year revenue grew 49.6% year-over-year. Notably, 2 other insiders also bought within the past 14 days, creating a cluster purchase pattern. However, Jeffrey's own prior purchase history at SI is concerning: his 4 previous buys at this ticker generated no gains at the 90-day mark (0 of 4 were profitable), with individual 90-day returns ranging from -2.4% to -20.7%. The company's unprofitable status and his track record of unsuccessful timing at this ticker warrant careful review of whether this purchase reflects conviction or other factors.

Ball Robert Joseph Buy
CEO & Executive Chairman
2,200 shares
$33,392
@ $15.18
Significance 3/10

CEO Ball buys 2,200 SI shares at $15.18; unprofitable company, poor prior timing, but cluster pattern.

Ball Robert Joseph, CEO & Executive Chairman of SHOULDER INNOVATIONS, INC., purchased 2,200 shares at $15.18 on 2026-03-13, increasing holdings by 0.8% to 278.9K shares. The company is unprofitable with a net income of $-8.7M on $11.8M latest-quarter revenue, though annual revenue grew 49.6% year-over-year. Ball's prior trading at SI has shown poor timing outcomes: 0 of 4 prior buys at this ticker were well-timed at the 90-day mark, with three exhibiting 90-day losses (−3.6%, −5.5%, −0.6%). His cross-ticker track record is also weak, with an average 90d return of −2.9% and a 0.00% 90-day win rate across 4 prior buys. However, 2 other insiders also bought within the past 14 days, establishing a cluster buy pattern. Stock has appreciated 15.8% over 30 days but remains 7.8% below its 52-week high.

$107,009
@ $14.86
Significance 4/10

CEO Ball purchases 7,200 shares at blended $14.86 (2 transactions, $107.0K) amid -8.0% 90-day decline and negative profit

Ball Robert Joseph, CEO & Executive Chairman, executed 2 separate purchases totaling 7,200 shares for $107,009.34 on 2025-12-11 and 2025-12-12 at prices of $14.83 and $14.89, increasing his holdings from 111,257 to 118,457 shares. The purchases occurred while SI traded -8.0% over the prior 90 days and -10.1% from its 52-week high of $16.08, amid a challenging operating environment: the company reported revenue of $11,756,000.00 but net loss of $-8,729,000.00 in its latest quarter. Ball's prior trades at SI showed negative 90-day outcomes (-20.0% on 2025-09-12 and -16.9% on 2025-09-11), and his cross-ticker track record across 2 prior buys averaged -2.1% over 90 days with a 0.00% win rate, offering no historical validation of buy-side timing accuracy. The current trading price of $14.45 is now 2.8% below Ball's blended purchase price of $14.86, suggesting the market has not yet validated this accumulation within days of execution.

Significance 4/10

CFO Jeffrey S. purchased 2,000 shares of SI over 2 days at average $14.82; stock now $14.45, off 8.0% in 90 days.

Jeffrey S., CFO of Shoulder Innovations, executed 2 separate purchases totaling 2,000 shares ($29,631.65) on December 11–12, 2025 at an average price of $14.82, raising his holdings to 54,445 shares. The current price of $14.45 is below his transaction prices, and the stock has declined 8.0% over 90 days and is 10.1% below its 52-week high. Notably, his prior two open-market purchases at this ticker have both underperformed on a 90-day horizon (−20.9% and −4.7%), with a 0.00% well-timed rate, establishing a pattern of purchasing at inopportune moments. Set against the company's negative net income (−$8.7M in the latest quarter), this purchase adds context but does not override the historical timing pattern or current price weakness.

Significance 4/10

CFO Points buys 1,600 shares at $15.67; now holds 52.4K shares amid -19.2M net loss

Points Jeffrey S., the Chief Financial Officer of Shoulder Innovations, purchased 1,600 shares at $15.67 on 2025-09-12 for $25,072.00, increasing his holdings to 52.4K shares. The transaction occurs while the company reported a net income of $-19.2M against revenue of $11.0M in the latest quarter, indicating significant operational losses. At a current price of $14.94, the shares are down 6.7% from the 52-week high of $16.02, though they have appreciated 6.0% over the past 30 days. This CFO-level buy adds to existing holdings, but his cross-ticker track record shows limited buy activity (1 prior buy, -1.2% average 30-day return), and his same-ticker activity at SI (1 prior trade on 2025-08-01) also showed a 30-day return of -1.2%, limiting the signal clarity of incremental accumulation.

$122,755
@ $15.34
Significance 4/10

CEO Ball Robert Joseph bought 8,000 shares at $15.34 blended average amid $-19.2M net loss.

CEO Ball Robert Joseph executed two separate purchases totaling 8,000 shares for $122,755.00 on consecutive days (September 11–12, 2025) at prices between $14.90 and $15.49, bringing his holdings from 103.3K to 111.3K shares. The company reported a quarterly net income of $-19.2M against revenue of $11.0M, indicating significant operational losses. The stock currently trades at $14.94, down 6.7% from its 52-week high of $16.02, while the 30-day trend is positive at +6.0%. This executive acquisition occurs within a negative earnings context and near the lower end of the recent trading range, adding to the observable facts but warranting review of broader company performance trends.

Pardo Geoffrey B Buy

$1,500,000
@ $15.00
Significance 7/10

Director Geoffrey B Pardo bought 100,000 shares of SI at $15.00 ($1.5M); cluster pattern: 6 other insiders also bought in 14 days.

Director Geoffrey B Pardo purchased 100,000 shares of Shoulder Innovations, Inc. at $15.00 on 2025-08-01, investing $1,500,000.00 in a recently listed company (4 trading days old). This transaction is part of a cluster buy pattern in which 6 other insiders also bought within the past 14 days, suggesting coordinated or synchronized confidence across the leadership group during the immediate post-IPO window. The company's current price of $14.16 (as of 2025-08-05) represents a modest decline from the transaction price, typical volatility for a fresh listing. The presence of derivative securities indicated in Table II (not yet populated in our database) suggests Pardo's full equity position extends beyond the 7,666 shares shown in Table I, warranting attention to the complete ownership picture once derivative holdings are disclosed.

Significance 6/10

CFO Jeffrey S. Points buys 50 shares of SI at $15.00; 6 other insiders also bought within 14 days

Jeffrey S. Points, the Chief Financial Officer of Shoulder Innovations, Inc., purchased 50 shares at $15.00 on 2025-08-01, establishing an initial position in the company just 4 trading days after the stock's recent listing. The transaction occurred in a pattern of coordinated insider activity: 6 other insiders also bought within the same 14-day window, which is notable for a newly public company. The CFO's entry-level purchase into his own company during a synchronized buying window by multiple executives suggests organized confidence at the leadership level at the moment of IPO, though the minimal time elapsed and early stage of public trading limit the ability to draw conclusions about longer-term valuation signals or performance expectations.

Gilde Healthcare Holding B.V. Buy
100,000 shares
$1,500,000
@ $15.00
Significance 6/10

Gilde Healthcare (10% owner) purchased 100,000 shares of SHOULDER INNOVATIONS for $1.5M; 6 other insiders buying in same 14-day window

Gilde Healthcare Holding B.V., a 10% shareholder, acquired 100,000 shares at $15.00 on 2025-08-01 for $1,500,000.00, increasing holdings from 2,280,482 to 2,380,482 shares (+4.4%). The purchase occurs within a cluster pattern in which 6 other insiders also bought within the past 14 days, suggesting coordinated or independently validated appetite for shares shortly after SHOULDER INNOVATIONS' recent listing. At the current price of $14.16 as of 2025-08-05 (4 trading days later), the stock has declined from the transaction price, though meaningful trend assessment is constrained by the company's very recent public listing. This filing contains a derivative conversion that places the insider's full economic position partially in Table II (not yet populated in the database), so the 2,380,482 post-transaction shares represent only the Form 4 Table I position and do not capture the complete holding profile. The cluster buy activity in an early-stage public market context warrants attention to whether this reflects underlying confidence in fundamentals or simply normal institutional positioning during the IPO window.
