Volatility continued into April as the closing of the Strait of Hormuz pushed oil above $126 per barrel, but markets rallied sharply after a June memorandum of understanding between the United States and Iran eased tensions, oil prices normalized, and the Information Technology sector led a broad-based recovery.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among holdings tied to semiconductor manufacturing, data center infrastructure, and defense. Leading contributors for the period included Vicor Corporation (VICR), PDF Solutions, Inc. (PDFS), FormFactor, Inc. (FORM), and Vishay Intertechnology, Inc. (VSH). The Fund's detractors were small relative to its contributors and included Super Micro Computer, Inc. (SMCI), Thermo Fisher Scientific, Inc. (TMO), and Huntington Ingalls Industries, Inc. (HII).</p><p style="text-align: left"><strong><span style="text-decoration: underline">Investment Themes</span></strong></p><p style="text-align: left">The Fund's major investment theme remains the importance of U.S. infrastructure. The Fund invests in lesser-known "pick and shovel" providers behind engineering, manufacturing, and technology development. Portfolio companies sell into data centers, life sciences laboratories, semiconductor and other manufacturing facilities, transportation infrastructure, energy systems, and defense-related markets. The U.S. has underinvested in many of these areas, which may create long-term opportunities.</p><p style="text-align: left">Four areas present throughout the portfolio are: Semiconductor manufacturing, data centers and artificial intelligence (AI) processing, U.S. manufacturing, and defense technology.</p><p style="text-align: left">Needham Investment Management LLC, the Fund's adviser, believes the AI buildout remains in an early stage. The Fund's strategy is to invest in companies developing new products and services and to hold those that execute successfully over time.</p></div> 100000 100000 100000 100000 100000 100000 100000 100000 101682 101882 103334 101677 103018 105671 106305 104344 101889 105743 106894 103940 102488 106864 108480 104809 104309 107958 111071 104299 104286 108932 111400 105988 108295 110986 113261 106922 107281 111200 114060 105281 111567 113912 117285 109403 111751 116397 120567 111878 112645 119932 124597 115991 108885 121131 125268 116244 113881 127515 132355 119585 108658 122815 128201 114285 107901 120350 127992 115346 105503 120807 126783 115047 111610 124218 131525 119794 112947 125030 132033 120298 115017 129179 134867 122421 116733 133716 142641 126332 114310 133937 142034 124947 104368 124075 127969 113020 108310 126560 131224 116549 98183 114781 119317 103360 107576 124633 133028 114172 111744 129017 140828 119012 112390 130900 142728 118335 119405 136128 149147 123093 114122 127318 140566 113281 123544 136261 150438 121938 125158 138286 153950 123388 122986 135467 151146 118213 126244 137845 149425 121833 131381 140812 152195 123210 136202 146165 159767 126876 140534 150385 161638 130440 140238 150221 163151 127034 132232 137922 151900 114976 114382 118955 129246 91698 133610 134710 149485 104703 143388 141914 164501 112362 149623 145158 168357 113774 163600 153401 181807 119020 165963 164514 186753 123202 163305 158524 184138 119202 162025 155102 184364 121793 189970 173971 209127 139180 199902 181797 219160 148257 210531 180989 218428 150487 215619 186646 222158 160723 214679 193336 217921 168228 216247 203302 230165 175802 215794 204230 226648 176147 230640 209266 242049 174343 236425 212805 244542 174945 242838 218874 252436 178353 239666 209053 240210 171272 252770 223191 257052 181353 258491 219793 246191 176026 256228 228449 247055 184966 223652 215008 215174 171630 218346 209592 212562 173542 220498 216390 215975 175945 189147 196971 191656 163440 193562 196707 184237 164663 171449 180250 170465 148822 194378 197161 191326 164969 187663 189803 185059 159852 164140 172203 169352 145155 170039 186325 182662 160424 181590 196050 192599 170240 170799 184571 181039 160808 185061 197282 196837 175648 183288 192671 194894 172465 186193 197823 197579 166929 173025 199931 194717 165622 197172 200709 194837 160339 211547 214414 209897 175027 227581 222100 216248 182248 206868 217813 209118 176977 194795 207438 198932 167674 174648 201939 188781 158724 196040 220769 211811 172227 217432 232479 227869 187240 229657 235056 226641 184036 267121 247779 243681 194966 280176 255772 249508 205877 260481 244518 235018 193484 275309 256071 237523 201976 278516 263998 241491 198784 273573 268905 242954 210324 268442 274759 248991 210159 268367 280443 257287 212588 251011 278383 261782 211087 260791 296902 296674 229684 250074 287827 278235 213320 255785 296914 295986 221532 236464 291224 279120 211903 209908 274236 258424 200308 202437 272397 267104 195796 214640 289663 292711 206364 237794 304378 305462 213750 246398 311082 311667 217212 240844 318281 314785 224584 260478 329265 313951 225612 286526 336322 313074 224557 271696 337245 306432 229157 274049 337177 302321 229322 314856 342408 299696 238611 336962 340779 302062 248442 317378 323833 283127 235060 373524 356873 301443 253540 415928 374955 315775 259760 454003 373848 324315 269079 <img alt="Ad2 Performance Graph" src="fp0099608-6_sa91.jpg" style="width: 348px;

Volatility continued into April as the closing of the Strait of Hormuz pushed oil above $126 per barrel, but markets rallied sharply after a June memorandum of understanding between the United States and Iran eased tensions, oil prices normalized, and the Information Technology sector led a broad-based recovery.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among holdings tied to semiconductor manufacturing, data center infrastructure, and defense. Leading contributors for the period included Vicor Corporation (VICR), PDF Solutions, Inc. (PDFS), FormFactor, Inc. (FORM), and Vishay Intertechnology, Inc. (VSH). The Fund's detractors were small relative to its contributors and included Super Micro Computer, Inc. (SMCI), Thermo Fisher Scientific, Inc. (TMO), and Huntington Ingalls Industries, Inc. (HII).</p><p style="text-align: left"><strong><span style="text-decoration: underline">Investment Themes</span></strong></p><p style="text-align: left">The Fund's major investment theme remains the importance of U.S. infrastructure. The Fund invests in lesser-known "pick and shovel" providers behind engineering, manufacturing, and technology development. Portfolio companies sell into data centers, life sciences laboratories, semiconductor and other manufacturing facilities, transportation infrastructure, energy systems, and defense-related markets. The U.S. has underinvested in many of these areas, which may create long-term opportunities.</p><p style="text-align: left">Four areas present throughout the portfolio are: Semiconductor manufacturing, data centers and artificial intelligence (AI) processing, U.S. manufacturing, and defense technology.</p><p style="text-align: left">Needham Investment Management LLC, the Fund's adviser, believes the AI buildout remains in an early stage. The Fund's strategy is to invest in companies developing new products and services and to hold those that execute successfully over time.</p></div> 10000 10000 10000 10000 10356 10397 10495 10429 10440 10423 10464 10481 10598 10440 10459 10414 10182 10214 10034 10136 11039 10671 10470 10947 10961 10879 10507 11187 11140 11084 10857 11374 11282 11496 11169 11673 11153 11504 11231 11628 11216 11626 11398 11725 11410 11745 11670 11668 11403 11851 11705 11857 11835 12074 11900 11961 11719 12098 11984 11778 12183 12393 12323 12239 12198 12663 12668 12516 12291 13048 13091 12976 11873 13178 13162 13004 12415 13873 13906 13378 11840 13361 13470 12785 11754 13093 13448 12904 11488 13143 13321 12870 12144 13514 13819 13401 12288 13602 13873 13458 12507 14054 14170 13695 12687 14547 14987 14133 12421 14571 14923 13978 11334 13498 13446 12643 11754 13769 13788 13038 10654 12487 12536 11563 11664 13559 13977 12772 12112 14036 14797 13314 12176 14241 14996 13238 12930 14810 15671 13770 12353 13851 14769 12673 13366 14824 15806 13641 13537 15044 16175 13803 13292 14738 15881 13224 13640 14996 15700 13629 14188 15319 15991 13783 14701 15902 16786 14193 15163 16361 16983 14592 15123 16343 17142 14211 14253 15005 15960 12862 12321 12941 13580 10258 14390 14655 15706 11713 15434 15439 17284 12570 16102 15792 17689 12728 17597 16689 19102 13315 17846 17898 19622 13782 17553 17246 19347 13335 17412 16874 19371 13625 20408 18927 21973 15570 21468 19778 23027 16585 22601 19690 22950 16835 23143 20306 23342 17980 23035 21033 22897 18819 23197 22118 24183 19667 23139 22219 23814 19705 24722 22767 25432 19503 25336 23152 25694 19571 26012 23812 26523 19952 25663 22743 25239 19160 27061 24281 27008 20288 27664 23912 25867 19692 27410 24853 25958 20692 23915 23391 22608 19200 23346 22802 22334 19414 23563 23542 22692 19683 20203 21429 20137 18284 20666 21400 19358 18421 18298 19610 17911 16648 20736 21450 20102 18455 20011 20649 19444 17882 17491 18734 17794 16238 18118 20271 19192 17946 19340 21329 20236 19044 18185 20080 19022 17989 19703 21463 20681 19649 19507 20961 20477 19293 19807 21522 20759 18674 18402 21751 20459 18528 20962 21836 20471 17937 22479 23327 22054 19580 24176 24163 22721 20388 21971 23696 21972 19798 20683 22568 20901 18757 18535 21969 19835 17756 20803 24018 22255 19267 23067 25292 23942 20946 24355 25572 23813 20588 28324 26956 25603 21811 29700 27826 26216 23031 27607 26602 24693 21645 29171 27858 24956 22595 29496 28721 25373 22238 28962 29255 25527 23529 28408 29892 26161 23510 28387 30510 27033 23782 26544 30286 27505 23614 27562 32301 31171 25694 26415 31313 29234 23864 27012 32302 31099 24782 24956 31683 29327 23705 22147 29835 27152 22408 21346 29635 28064 21903 22623 31513 30755 23086 25051 33114 32094 23912 25947 33843 32746 24299 25354 34626 33074 25124 27410 35821 32986 25239 30142 36589 32894 25121 28569 36690 32196 25635 28808 36682 31765 25654 33080 37251 31489 26693 35392 37074 31737 27793 33323 35231 29748 26296 39207 38825 31672 28363 43643 40792 33178 29059 47627 40672 34075 30101 <img alt="Ad2 Performance Graph" src="fp0099608-5_sa91.jpg" style="width: 348px;

Volatility continued into April as the closing of the Strait of Hormuz pushed oil above $126 per barrel, but markets rallied sharply after a June memorandum of understanding between the United States and Iran eased tensions, oil prices normalized, and the Information Technology sector led a broad-based recovery.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among holdings tied to semiconductor manufacturing, data center infrastructure, and defense. Leading contributors included nLIGHT, Inc. (LASR), which continued to benefit from strength in its laser-based defense business; Vicor Corporation (VICR), which reported strong results tied to AI-related power delivery demand; Arteris, Inc. (AIP), which raised guidance following expanded hyperscaler adoption of its technology; and Vishay Intertechnology, Inc. (VSH), which advanced its capacity expansion plans and raised $750 million to fund growth and reduce debt. The Fund's detractors were small relative to its contributors and included Vital Farms, Inc. (VITL) and Huntington Ingalls Industries, Inc. (HII).</p><p style="text-align: left"><strong><span style="text-decoration: underline">Investment Themes</span></strong></p><p style="text-align: left">Needham Investment Management LLC (the "Adviser") looks to invest in companies when they are investing in something new that is supported by an established business. The Fund's major investment theme remains the importance of U.S. infrastructure. The Fund invests in lesser-known "pick and shovel" providers behind engineering, manufacturing, and technology development. Portfolio companies sell into data centers, life sciences laboratories, semiconductor and other manufacturing facilities, transportation infrastructure, energy systems, and defense-related markets. The U.S. has underinvested in many of these areas, which may create long-term opportunities.</p><p style="text-align: left">Four areas present throughout the portfolio are: Semiconductor manufacturing, data centers and artificial intelligence (AI) processing, U.S. manufacturing, and defense technology.</p><p style="text-align: left">The Adviser believes the AI buildout remains in an early stage. The Fund's strategy is to invest in companies developing new products and services and to hold those that are successful over time.</p></div> 100000 100000 100000 100000 100000 100000 99507 101882 101624 100897 105671 104116 101750 105743 105349 102692 106864 107289 102512 107958 106313 101480 108932 109972 105967 110986 110908 104756 111200 110779 112562 113912 116811 113504 116397 118621 113792 119932 122026 109363 121131 122167 109975 127515 126929 107996 122815 123315 108703 120350 124976 106253 120807 125098 115771 124218 132974 116619 125030 134015 116007 129179 136319 119399 133716 144806 113462 133937 141417 101777 124075 123522 101621 126560 125455 92570 114781 110795 103464 124633 123590 107637 129017 131572 108287 130900 129791 114466 136128 133744 104602 127318 123821 113544 136261 133358 117447 138286 134661 112515 135467 128850 117718 137845 127793 123625 140812 131429 127456 146165 139165 134028 150385 142354 134571 150221 140786 129808 137922 130622 112082 118955 105676 130833 134710 121416 141142 141914 132890 151392 145158 137997 169600 153401 142739 172434 164514 151112 166947 158524 147875 165078 155102 148998 191506 173971 175272 204202 181797 191654 213567 180989 200895 220418 186646 207528 218972 193336 200998 222806 203302 205380 226263 204230 199515 242164 209266 208872 243044 212805 201264 248763 218874 204922 247066 209053 197065 265859 223191 206293 280937 219793 196218 282683 228449 197087 245694 215008 170672 239451 209592 171417 241532 216390 172200 214076 196971 151073 211995 196707 148220 194139 180250 139044 220856 197161 154612 217500 189803 153159 197159 172203 139381 206289 186325 152611 216694 196050 155096 206289 184571 145140 226831 197282 159577 228979 192671 157849 225287 197823 153954 209981 199931 152165 240055 200709 152193 263215 214414 164812 282347 222100 172517 267310 217813 163537 258382 207438 152750 240525 201939 140969 261335 220769 153803 285435 232479 172221 292685 235056 166698 325914 247779 180238 338937 255772 185278 318463 244518 171012 341555 256071 180170 332761 263998 179870 339273 268905 194594 328465 274759 192440 330613 280443 194997 311548 278383 192410 341958 296902 216002 327861 287827 198320 338467 296914 204590 317120 291224 190740 287247 274236 176275 289865 272397 175147 331284 289663 186391 364581 304378 197367 374851 311082 200729 386196 318281 212601 403717 329265 221434 429092 336322 228598 402983 337245 227034 416694 337177 224127 461120 342408 233039 494233 340779 232475 466810 323833 217834 566699 356873 249835 638205 374955 264431 692708 373848 273831 <img alt="Ad2 Performance Graph" src="fp0099608-8_sa91.jpg" style="width: 348px;

Volatility continued into April as the closing of the Strait of Hormuz pushed oil above $126 per barrel, but markets rallied sharply after a June memorandum of understanding between the United States and Iran eased tensions, oil prices normalized, and the Information Technology sector led a broad-based recovery.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among holdings tied to semiconductor manufacturing, data center infrastructure, and defense. Leading contributors included nLIGHT, Inc. (LASR), which continued to benefit from strength in its laser-based defense business; Vicor Corporation (VICR), which reported strong results tied to AI-related power delivery demand; Arteris, Inc. (AIP), which raised guidance following expanded hyperscaler adoption of its technology; and Vishay Intertechnology, Inc. (VSH), which advanced its capacity expansion plans and raised $750 million to fund growth and reduce debt. The Fund's detractors were small relative to its contributors and included Vital Farms, Inc. (VITL) and Huntington Ingalls Industries, Inc. (HII).</p><p style="text-align: left"><strong><span style="text-decoration: underline">Investment Themes</span></strong></p><p style="text-align: left">Needham Investment Management LLC (the "Adviser") looks to invest in companies when they are investing in something new that is supported by an established business. The Fund's major investment theme remains the importance of U.S. infrastructure. The Fund invests in lesser-known "pick and shovel" providers behind engineering, manufacturing, and technology development. Portfolio companies sell into data centers, life sciences laboratories, semiconductor and other manufacturing facilities, transportation infrastructure, energy systems, and defense-related markets. The U.S. has underinvested in many of these areas, which may create long-term opportunities.</p><p style="text-align: left">Four areas present throughout the portfolio are: Semiconductor manufacturing, data centers and artificial intelligence (AI) processing, U.S. manufacturing, and defense technology.</p><p style="text-align: left">The Adviser believes the AI buildout remains in an early stage. The Fund's strategy is to invest in companies developing new products and services and to hold those that are successful over time.</p></div> 10000 10000 10000 10393 10397 10654 10580 10423 10767 10932 10440 10922 10917 10214 10243 11938 10671 11160 12046 10879 11312 11976 11084 11496 12138 11496 11778 12240 11504 11917 12343 11626 12137 12316 11745 12026 12186 11851 12440 12721 12074 12546 12570 12098 12531 13500 12393 13214 13602 12663 13418 13631 13048 13804 13097 13178 13820 13160 13873 14358 12921 13361 13950 13001 13093 14137 12700 13143 14151 13836 13514 15042 13926 13602 15160 13847 14054 15421 14244 14547 16381 13529 14571 15997 12132 13498 13973 12107 13769 14192 11028 12487 12533 12317 13559 13981 12807 14036 14884 12879 14241 14682 13605 14810 15129 12428 13851 14007 13487 14824 15086 13945 15044 15233 13350 14738 14576 13965 14996 14456 14658 15319 14867 15100 15902 15742 15873 16361 16103 15931 16343 15926 15355 15005 14776 13263 12941 11954 15465 14655 13735 16675 15439 15033 17885 15792 15610 20022 16689 16147 20335 17898 17094 19686 17246 16728 19453 16874 16855 22546 18927 19827 24030 19778 21680 25118 19690 22725 25917 20306 23476 25727 21033 22737 26161 22118 23233 26556 22219 22569 28405 22767 23628 28489 23152 22767 29151 23812 23181 28930 22743 22292 31114 24281 23336 32863 23912 22196 33051 24853 22295 28701 23391 19307 27959 22802 19391 28179 23542 19479 24969 21429 17089 24717 21400 16767 22623 19610 15729 25711 21450 17490 25312 20649 17325 22933 18734 15767 23984 20271 17263 25173 21329 17545 23951 20080 16418 26330 21463 18052 26558 20961 17856 26118 21522 17415 24326 21751 17213 27796 21836 17216 30493 23327 18644 32700 24163 19515 30941 23696 18499 29898 22568 17279 27813 21969 15947 30199 24018 17398 32969 25292 19482 33792 25572 18857 37613 26956 20389 39096 27826 20959 36717 26602 19345 39373 27858 20381 38338 28721 20347 39071 29255 22013 37817 29892 21769 38053 30510 22058 35837 30286 21766 39324 32301 24434 37686 31313 22434 38884 32302 23143 36423 31683 21577 32977 29835 19940 33254 29635 19813 38004 31513 21085 41800 33114 22326 42965 33843 22707 44244 34626 24050 46240 35821 25049 49124 36589 25859 46126 36690 25682 47676 36682 25353 52741 37251 26362 56515 37074 26298 53357 35231 24642 64754 38825 28262 72901 40792 29913 79107 40672 30976 <img alt="Ad2 Performance Graph" src="fp0099608-7_sa91.jpg" style="width: 348px;

Volatility continued into April with the closing of the Strait of Hormuz, which pushed oil to a peak of $126 per barrel, before a June memorandum of understanding between the United States and Iran eased tensions. Small-cap stocks staged a significant recovery in the second quarter as investor interest in the asset class accelerated, merger and acquisition activity picked up, and Information Technology led market gains.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among semiconductor, communications infrastructure, and specialty materials holdings. Leading contributors for the period included Arteris, Inc. (AIP), which reported strong bookings and raised guidance; Vishay Intertechnology, Inc. (VSH), which advanced its capacity expansion strategy; and TTM Technologies, Inc. (TTMI) and nLIGHT, Inc. (LASR), which benefited from improving fundamentals and renewed investor confidence earlier in the period. The Fund's detractors were small relative to its contributors and included CoStar Group, Inc. (CSGP), Harmonic, Inc. (HLIT), and Lantronix, Inc.

Volatility continued into April with the closing of the Strait of Hormuz, which pushed oil to a peak of $126 per barrel, before a June memorandum of understanding between the United States and Iran eased tensions. Small-cap stocks staged a significant recovery in the second quarter as investor interest in the asset class accelerated, merger and acquisition activity picked up, and Information Technology led market gains.</p><p style="text-align: left">The key factor affecting the Fund's performance was stock selection, particularly among semiconductor, communications infrastructure, and specialty materials holdings. Leading contributors for the period included Arteris, Inc. (AIP), which reported strong bookings and raised guidance; Vishay Intertechnology, Inc. (VSH), which advanced its capacity expansion strategy; and TTM Technologies, Inc. (TTMI) and nLIGHT, Inc. (LASR), which benefited from improving fundamentals and renewed investor confidence earlier in the period. The Fund's detractors were small relative to its contributors and included CoStar Group, Inc. (CSGP), Harmonic, Inc. (HLIT), and Lantronix, Inc.
